Detailed Description

Embodiments of the invention are described in further detail below with reference to the accompanying drawings, it being noted that the examples are merely illustrative of the invention and should not be considered as limiting, and that all features disclosed in the examples of the invention, or steps in all methods or processes disclosed, may be combined in any way, except for mutually exclusive features and/or steps.

The invention provides a dovetail type hoop for fixing equipment on an angle steel tower body, which is used for stably fixing the equipment on the angle steel tower and comprises a first hoop part 10 and a second hoop part 20, wherein the first hoop part 10 and the second hoop part 20 clamp an angle steel tower body 30 in the middle, and the first hoop part 10 and the second hoop part 20 are connected through a locking part 40, and referring to the attached drawings 1 and 4. The angle tower body 30 is generally a long steel strip with two perpendicular sides and an angle shape, and the lengths of the two sides of the long steel strip selected on the angle tower are generally the same. Specifically, the first hoop member 10 is installed on the inner side of the angle tower body 30, the second hoop member 20 is installed on the outer side of the angle tower body 30, the first hoop member 10 and the second hoop member 20 are of a double-layer structure, and the double-layer structure can enable the first hoop member 10 and the second hoop member 20 to be stably installed on the angle tower body 30. If the first and second clip members 10 and 20 have a single-layer structure, the first and second clip members 10 and 20 need to have a sufficient thickness in order to ensure stability after installation. Referring to fig. 5, the first collar member 10 having a single-layer structure is shown in the drawing, and compared to the first collar member 10 having a double-layer structure shown in fig. 2, the first collar member 10 having a single-layer structure requires more materials for manufacturing, has high manufacturing cost, heavy parts, and is inconvenient to carry, and in an actual installation test, the effect of the first collar member 10 having a single-layer structure after being installed on the body 30 of the angle iron tower is substantially the same as that of the first collar member 10 having a double-layer structure, so the first collar member 10 and the second collar member 20 preferably have a double-layer structure.

The first clip member 10 includes a first mounting plate 11, a second mounting plate 12, and a first connecting plate 13, the first connecting plate 13 connecting the first mounting plate 11 and the second mounting plate 12; the second clip member 20 includes a third mounting plate 21, a fourth mounting plate 22, and a second connecting plate 23, and the second connecting plate 23 connects the third mounting plate 21 and the fourth mounting plate 22. The locking member 40 connects the first connecting plate 13 and the second connecting plate 23, so that the first hoop member 10 and the second hoop member 20 sandwich the angle-steel tower body 30. As a further preferred scheme, the first mounting plate 11 and the second mounting plate 12 are the same in shape, the third mounting plate 21 and the fourth mounting plate 22 are the same in shape, the first connecting plate 13 is perpendicular to the plane of the first mounting plate 11 and the second mounting plate 12, and the second connecting plate 23 is perpendicular to the plane of the third mounting plate 21 and the fourth mounting plate 22. When the clamp is installed on the angle steel tower body 30, the first installation plate 11 and the second installation plate 12 on the first clamp 10 are abutted against the inner side of the angle steel tower body 30, and the third installation plate 21 and the fourth installation plate 22 on the second clamp 20 are abutted against the outer side of the angle steel tower body 30. When the locking member 40 connects the first connecting plate 13 and the second connecting plate 23, the force provided by the locking member 40 to the first collar member 10 and the second collar member 20 is always perpendicular to the length direction of the angle tower body 30, and the force along the length direction of the angle tower body 30 is not resolved. Furthest's the clamp force of having remain between clamp and angle steel tower body 30 to promote the maximum frictional force of clamp when sliding on angle steel tower body 30, make the clamp be difficult for sliding behind the angle steel tower body 30.

In some other embodiments, the first and second clip members 10 and 20 can also be a multi-layer structure, for example, three or more layers. The first and second ferrule members 10 and 20 having the three-layer structure can achieve similar effects to the first and second ferrule members 10 and 20 having the two-layer structure when they are mounted. However, in the factory processing process, the first clamp member 10 and the second clamp member 20 with the double-layer structure can be formed (sheet metal parts) by sheet metal stamping and bending, and the processing is easy and the processing cost is low; however, in general, the three-layer structure cannot be directly processed by a sheet metal process, and a casting mold mode is selected, so that the processing is complicated, and the processing cost is high. Therefore, the first clip member 10 having a two-layer structure is preferable in the case where the difference in performance is not large, and cost saving can be achieved.

Preferably, the first mounting plate 11 is connected to the second mounting plate 12 through two first connecting plates 13, and the third mounting plate 21 is connected to the fourth mounting plate 22 through two second connecting plates 23. Correspondingly, at least two or more than three locking members 40 are arranged for connecting the first connecting plate 13 and the second connecting plate 23, and at least one locking member 40 is arranged between each first connecting plate 13 and the second connecting plate 23. The locking member 40 can enable the first hoop member 10 and the second hoop member 20 to be fixed on the angle steel tower body 30 in a balanced mode, and the situation that one side of the first hoop member is fixed tightly and one side of the second hoop member is fixed loosely cannot occur.

Preferably, referring to fig. 2, the first connecting plate 13 is provided with a first connecting hole 14, the second connecting plate 23 is provided with a second connecting hole 24, and the first collar member 10 and the second collar member 20 can be connected by passing bolts and nuts through the first connecting hole 14 and the second connecting hole 24. This connection has an advantage that the bolt and the nut can be tightened easily, and the first clip member 10 and the second clip member 20 can be fixed firmly by tightening the bolt and the nut. In some other embodiments, the first clamp member 10 and the second clamp member 20 can be connected by passing the cable tie through the first connecting hole 14 and the second connecting hole 24, the cable tie can be made of steel cable tie, the connection method has the advantages of quick fixation, but has the defects of difficult tightening, and therefore the fixation is weaker than bolt and nut. The clamp is fixed on the angle steel tower body 30, the primary purpose is to fix firmly, therefore, the bolt and nut which can be tightened is the preferable connection mode in the invention, and the locking piece 40 comprises a bolt 41, a flat gasket 42, a spring gasket 43 and a nut 44. Of course, the locking member 40 can be selected from other conventional connection methods according to different application scenarios, and the selection of the connection method is not limited in this invention.

Preferably, referring to fig. 2 and 3, the first mounting plate 11 is provided with a first mounting surface 15 and a second mounting surface 16 which contact the angle steel tower body 30, the third mounting plate 21 is provided with a third mounting surface 25 and a fourth mounting surface 26 which contact the angle steel tower body 30, (the first mounting plate 11 and the second mounting plate 12 have the same shape, the second mounting plate 12 is also provided with the first mounting surface 15 and the second mounting surface 16 which contact the angle steel tower body 30, the third mounting plate 21 and the fourth mounting plate 22 have the same shape, the fourth mounting plate 22 is also provided with the third mounting surface 25 and the fourth mounting surface 26 which contact the angle steel tower body 30), the first mounting surface 15 and the second mounting surface 16 contact the inner side of the angle steel tower body 30, and the third mounting surface 25 and the fourth mounting surface 26 contact the outer side of the angle steel tower body 30. Because two sides of the angle steel tower body 30 are perpendicular to each other, in order to enable the first clamp member 10 and the second clamp member 20 to be well mounted on the angle steel tower body 30, the first mounting surface 15 and the second mounting surface 16 form an angle of 90 degrees, and the third mounting surface 25 and the fourth mounting surface 26 also form an angle of 90 degrees, so that the first clamp member 10 and the second clamp member 20 can be just attached to the angle steel tower body 30.

Further, when the angle between the first mounting surface 15 and the second mounting surface 16 and the angle between the third mounting surface 25 and the fourth mounting surface 26 are 90 degrees, respectively. After being fixed in angle steel tower body 30 with the clamp, the clamp force between first clamp 10 and the second clamp 20 is controlled by retaining member 40, because first clamp 10, second clamp 20 can laminate with angle steel tower body 30 just, after first clamp 10, the laminating of second clamp 20, because the laminating is inseparable, does not have the space of moving, installer just can't or hardly spin nut 44 again. At this time, the nut 44 is fixed to the bolt 41 by the repulsive force generated by the spring washer 43 when tightened, but such connection is not firm. Because conventional spring washers 43 will accommodate the deformation in the tightened state over time, resulting in less spring back force, nuts 44 will loosen, indirectly resulting in first and second clamp members 10, 20 not being able to clamp angle tower body 30 tightly, which may slip down along angle tower body 30 with the equipment if the equipment mounted thereon is heavy.

In order to ensure that the clamp and the equipment thereon are not loosened after being mounted on the angle steel tower body 30 for a long time, the clamp can still be firmly fixed on the angle steel tower body 30 and cannot slide downwards. The adopted technical scheme is as follows: when the clamp is completely fixed to the turret body 30, the locking member 40 elastically deforms the first clamp member 10 or the second clamp member 20. Specifically, in this embodiment, referring to fig. 3, mainly, the first clamp member 10 is elastically deformed, a notch 17 is disposed on one side of the first mounting plate 11, which is in contact with the angle-steel tower body 30, the notch 17 is in an angle shape, the notch 17 divides the first clamp member 10 into a left part and a right part, so that the first clamp member 10 has a capability of deforming in a direction of the notch 17, meanwhile, a first hole 18 is disposed at a corner position of the notch 17, the first hole 18 makes the corner position of the notch 17 of the first clamp member 10 not easily break in a deformation process, and the first hole 18 is preferably a circular hole. Meanwhile, an arc 19 is arranged on one side, far away from the angle steel tower body 30, of the first mounting plate 11, the opening back of the arc 19 is opposite to the position of the angle steel tower body 30 (the opening direction of the arc 19 is opposite to the opening direction of the notch 17), the length of one side, far away from the angle steel tower body 30, of the first mounting plate 11 is prolonged by the arc 19, and one side, far away from the angle steel tower body 30, of the first clamping hoop part 10 on the first mounting plate 11 in the deformation process cannot be broken due to stretching. As a further preferred solution, the angle between the first mounting surface 15 and the second mounting surface 16 is in the interval of 80 ° to 90 °, preferably 85 °; the third mounting surface 25 and the fourth mounting surface 26 form an angle of 90 °, and the notch 17 forms an angle in the interval of 60 ° to 120 °, preferably 90 °. Although the first collar member 10 cannot be completely attached to the angle tower body 30 in an undeformed state, the first collar member 10 is elastically deformed after the first collar member 10 and the second collar member 20 are completely attached to the angle tower body 30 by tightening the locking member 40, and at this time, the included angle formed between the first mounting surface 15 and the second mounting surface 16 is 90 degrees, and the first mounting surface 15 and the second mounting surface 16 are completely attached to the inner side of the angle tower body 30. In this state, since the first clip member 10 is elastically deformed, the first clip member 10 transmits an elastic force to the nut 44 in the locking member 40, and the elastic force generated by the first clip member 10 is much greater than the resilient force generated by the spring washer 43, so that the nut 44 is firmly fixed to the bolt 41 and is difficult to be loosened after being fixed for a long time. In addition, the clamping force transmitted to the angle steel tower body 30 by the first clamp member 10 and the second clamp member 20 in the deformation state is also larger than the clamping force when the first clamp member 10 is not deformed, so that the maximum friction force of the clamp when the clamp slides on the angle steel tower body 30 can be improved, and the bearing capacity of the clamp is increased. During the deformation of the first hoop member 10, the first hoop member 10 will transmit a part of the force to the second hoop member 20 through the locking member 40, and the second hoop member 20 may also be deformed, so as to avoid the fracture of the second hoop member 20 at the boundary position between the third mounting surface 25 and the fourth mounting surface 26, a second hole 27 is provided at the corner position of the third mounting plate 21 contacting the angle tower body 30, and the second hole 27 is preferably a circular hole. It should be noted that even if the second clip member 20 is deformed, the deformation degree is slight because the included angle formed by the third mounting surface 25 and the fourth mounting surface 26 is 90 °, the second clip member 20 is already attached to the angle-steel tower body 30, and the deformation space is insufficient.

Preferably, in some other embodiments, the second clip member 20 can be deformed to fix the clip firmly. The angle formed between the first mounting surface 15 and the second mounting surface 16 is 90 °, and the angle formed between the third mounting surface 25 and the fourth mounting surface 26 is in the interval of 90 ° to 100 °, preferably 95 °. In some other embodiments, the first clip member 10 and the second clip member 20 are deformed together to fix the clips firmly. The included angle formed between the first mounting surface 15 and the second mounting surface 16 is in the range of 80-90 degrees, and preferably 85 degrees; the third mounting surface 25 and the fourth mounting surface 26 form an angle in the interval of 90-100 degrees, preferably 95 degrees.

Preferably, the second clamp member 20 is used for connecting equipment, and the third mounting plate 21 and the fourth mounting plate 22 are provided with mounting holes 28, and the third mounting plate 21 and the fourth mounting plate 22 are provided with at least two mounting holes 28, respectively, and the mounting holes 28 are used in pairs, because the single mounting hole 28 cannot limit the rotation of the equipment when the equipment is fixed. In addition, because the second hoop member 20 has a double-layer structure, when the second hoop member 20 is connected to a device through the mounting hole 28, the third mounting plate 21 and the fourth mounting plate 22 may be bent, so that the support member 50 is disposed between the third mounting plate 21 and the fourth mounting plate 22, the support member 50 can support the third mounting plate 21 and the fourth mounting plate 22, and the support member 50 is provided with the bevel 51, so that the support member 50 can be conveniently installed between the third mounting plate 21 and the fourth mounting plate 22. As a further preferred option, since the mounting holes 28 are used in pairs, referring to fig. 2, the supporting member 50 can be two cylindrical sleeves, or two through holes are provided in one supporting member 50, and the size of the through holes is the same as that of the mounting holes 28.

Preferably, the first clamp member 10, the second clamp member 20, and the assembled dovetail clamp are symmetrical. Due to the design, the hoop is not distinguished in the direction during installation, and the installation is convenient.

Preferably, the first and second clip members 10 and 20 are made of a high-strength steel material, which is not easily deformed and does not rust. The clamp adopts the equipment mode of part formula, and the clamp need not the welding in the installation, and the installation is simple swift, and the installation is accomplished the back product surface and does not have the welding point, has better corrosion resisting ability, work load when can reducing the later maintenance. The bolt 41 and the nut 44 in the locker 40 are surface-treated to increase the hardness thereof and make it less prone to rust.

The above description is only an embodiment of the invention, but the scope of the invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be included in the scope of the invention, and therefore, the scope of the invention should be subject to the scope defined by the claims.
