Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The first embodiment is as follows:

fig. 1 is a schematic structural diagram of a transformer operation safety facility according to an embodiment of the present application. As shown in fig. 1, the transformer operation safety facility comprises a protection device single body, wherein the protection device single body comprises a mounting part 10 which is used for being mounted at the top of a transformer body; a longitudinal connection part 20, the bottom of the longitudinal connection part 20 being connected to the mounting part 10; and a through hole portion connected to an upper portion of the longitudinal connection portion 20, and a through hole of the through hole portion is formed by a continuous annular inner wall for passing the safety belt and/or the protection cord therethrough.

The transformer operation safety facility that this embodiment provided can install protector monomer at the top of transformer body through setting up installation department 10, utilizes the through-hole portion that is located the top of longitudinal joint portion 20 to be passed by safety belt or protection rope, can rise the position of the link of protection rope or safety belt, prevents that prior art, staff hang the technical problem of low usefulness with protection rope or safety belt system in the rings of transformer and the height that produces. Even if the staff slips or falls from the top of the transformer body, the falling height of the staff is obviously reduced, so that the safety of the staff in the operation of the top of the transformer is improved.

In a possible realization, the through hole portion is formed by a suspension loop 30, the suspension loop 30 being mounted on top of the longitudinal connection portion 20.

Forming the through hole portion in the form of the hanging ring 30 can reduce the processing of the longitudinal connecting portion 20. Moreover, the hanging ring 30 forms the through hole part, the chamfers at the two ends of the through hole part are soft and not as sharp as the end part of the through hole part processed on the longitudinal connecting part 20, and the safety belt is prevented from being worn by the through hole part, so that the safety of workers is improved.

In one possible implementation, the suspension loops 30 are rotatably mounted on top of the longitudinal connection 20.

The hanging ring 30 is rotatably installed on the top of the longitudinal connecting portion 20, so that the hanging ring 30 can be driven by a safety belt or a protective rope tied on the hanging ring 30 to rotate relative to the top of the longitudinal connecting portion 20. In this way, when the worker is at different positions relative to the longitudinal connecting portion 20, the hanging ring 30 can swing to different positions, so that the safety belt or the protection rope can be prevented from being wound on the longitudinal connecting portion 20 to affect the moving range of the worker.

In a possible realization, the suspension loops 30 are arranged rotating with the top of the longitudinal connection 20 along a horizontal axis.

Arranged to rotate with the longitudinal connecting portion 20 along a horizontal axis, when a worker moves to opposite sides of the longitudinal connecting portion 20, the suspension loop 30 can be caused to rotate along the horizontal axis with respect to the longitudinal connecting portion 20, thereby preventing a safety belt or a protection rope from being wound around the longitudinal connecting portion 20.

Fig. 3 is a schematic sectional view of the top of a possible implementation of the transformer operation safety facility according to an embodiment of the present application. As shown in fig. 3, in one possible implementation, the suspension loop 30 comprises a C-shaped portion 31; and a pivot shaft portion 32, the pivot shaft portion 32 being rotatably connected to the top of the longitudinal connecting portion 20 and fixedly connected to both ends of the C-shaped portion 31.

The form that sets up pivot axial region 32 and C shape portion 31 and constitute link 30 jointly can utilize pivot axial region 32 and longitudinal connecting portion 20 relative rotation to take place the friction to when having avoided the ring shape to pass longitudinal connecting portion 20, the tip in the hole on the longitudinal connecting portion 20 and the local contained angle that the ring passed this hole are great, to the comparatively serious problem of link 30 wearing and tearing, have improved the life of link 30.

In a possible implementation manner, the longitudinal connecting portion 20 is tubular, the longitudinal connecting portion 20 includes connecting holes 21, the connecting holes 21 are penetrated by the hanging ring 30, and the number of the connecting holes 21 is one or two.

By adopting the mode that the hanging ring 30 is directly penetrated in the connecting hole 21, the processing is simple and convenient, and the manufacturing cost of the transformer operation safety facility is favorably reduced.

Fig. 2 is a schematic sectional view of the top of the transformer operation safety facility of the embodiment shown in fig. 1. As shown in fig. 2, in this embodiment, specifically, the number of the connecting holes 21 may be one, the hanging ring 30 may be a circular ring with an opening before passing through the connecting holes 21, and after the hanging ring 30 passes through the connecting holes 21, the opening of the hanging ring 30 may be closed or the opening of the hanging ring 30 may be welded.

Fig. 4 is a schematic sectional view of the top of a possible implementation of the transformer operation safety facility according to an embodiment of the present application. As shown in fig. 4, in another possible implementation manner, there may be two connection holes 21 on the longitudinal connection portion 20, and the hanging ring 30 may pass through the two connection holes 21, where the connection line direction of the two connection holes 21 is the rotation direction of the hanging ring 30 relative to the longitudinal connection portion 20. After the hanging ring 30 passes through the two connecting holes 21, the opening of the hanging ring 30 can be folded or the opening of the hanging ring 30 can be welded.

Fig. 5 is a schematic sectional view of the top of a possible implementation of the transformer operation safety facility according to an embodiment of the present application. As shown in fig. 5, in a possible implementation manner, a vertical rotating shaft 33 is further included, and the vertical rotating shaft 33 is fixedly connected with the hanging ring 30 and is connected with the top of the longitudinal connecting portion 20 in an axially fixed and circumferentially rotating manner.

The hanging ring 30 is mounted on the top of the longitudinal connecting portion 20 by means of the vertical rotating shaft 33, so that the hanging ring 30 can rotate 360 degrees along the plumb line relative to the top of the longitudinal connecting portion 20. No matter the operator moves to any direction relative to the protecting device unit connected with the safety belt on the transformer body, the hanging ring 30 is driven by the safety belt, and after the protecting device unit rotates relative to the protecting device unit, the protecting device unit cannot be wound by the safety belt.

Specifically, the hanging ring 30 can be vertically arranged, the lower end of the hanging ring 30 is fixedly connected with the vertical rotating shaft 33, and the shape of the combination of the hanging ring and the vertical rotating shaft is similar to that of a lifting bolt. The specific implementation manner of the connection between the vertical rotating shaft 33 and the top of the longitudinal connecting portion 20 through axial fixation and circumferential rotation may be that a hollow pipe portion 34 is disposed on the outer peripheral surface of the longitudinal connecting portion 20, the hollow pipe portion 34 extends in the vertical direction, and the vertical rotating shaft 33 is rotatably connected with the hollow pipe portion 34.

More specifically, a possible implementation manner is that an external thread may be provided at a lower portion of the vertical rotating shaft 33, and after the vertical rotating shaft 33 is inserted into the hollow tube portion 34, two nuts 10 are screwed at the lower portion of the vertical rotating shaft 33, wherein the lower nut 10 serves as a locking nut of the upper nut 10, so as to prevent the vertical rotating shaft 33 from rotating relative to the hollow tube portion 34 and driving the nut 10 and the vertical rotating shaft 33 to rotate. Referring specifically to fig. 5, fig. 5 is a partial cross-sectional view illustrating an implementation manner of connecting the suspension loop 30 and the longitudinal connection portion 20 in the transformer operation safety facility according to an embodiment of the present application.

More specifically, other possible implementations are: a split pin is provided at a lower portion of the vertical rotation shaft 33, and the split pin passes through the vertical rotation shaft 33 in a radial direction after the vertical rotation shaft 33 is inserted into the hollow tube part 34; alternatively, when the vertical rotation shaft 33 does not need to be detached from the hollow tubular portion 34, the nut 10 may be screwed onto the vertical rotation shaft 33 in such a manner that the nut 10 is disposed at a lower portion of the vertical rotation shaft 33, and then the nut 10 and/or the external thread portion of the vertical rotation shaft 33 may be broken, thereby preventing the nut 10 from rotating; or, when the vertical rotating shaft 33 does not need to be detached from the hollow tube part 34, the vertical rotating shaft 33 may be bent outward, so that the vertical rotating shaft 33 cannot move relative to the hollow tube part 34 in the axial direction, and the rotating angle of the vertical rotating shaft 33 may not reach 360 ° in this case; or, the part of the vertical rotating shaft 33 protruding downwards from the bottom of the hollow pipe can be hammered, so that the diameter of the part is larger than the inner diameter of the hollow pipe, the vertical rotating shaft 33 cannot be pulled out from bottom to top, the hanging ring 30 is fixedly mounted at the top of the hollow pipe, and the vertical rotating shaft 33 cannot be pulled out from top to bottom, so that axial fixation is realized.

As shown in fig. 1, in one possible implementation, the mounting portion 10 includes a mounting hole penetrating through the mounting portion 1 in a height direction of the mounting portion 10 for passing through a threaded fastener 11 connected with a suspension hole of the transformer body. Specifically, in the present embodiment, the mounting portion 10 may be a rectangular flat iron, or may actually be a disk-shaped discus or a rectangular block. As long as the mounting portion 10 can protrude laterally from the side surface of the longitudinal connecting portion 20, and can form a mounting hole penetrating in the height direction, and through which the threaded fastener 11 can pass.

The threaded fastener 11 penetrates through the mounting hole of the mounting part 10 and is directly connected with the hanging ring hole of the transformer body, the transformer can be conveniently mounted on the transformer body by utilizing the existing structural elements on the transformer body, additional drilling on the transformer body is not needed, the influence on the transformer body is reduced, and meanwhile, the operation efficiency of mounting the protection device monomer on the transformer body is improved.

In another possible implementation manner, the mounting portion 10 may not protrude from the side wall of the bottom of the longitudinal connecting portion 20, the mounting portion 10 may be a bottom plate of a steel pipe used as the longitudinal connecting portion 20, the bottom plate may block the bottom of the steel pipe and be fixedly connected with the steel pipe, and a length of stud is welded on the bottom surface of the bottom plate. During operation, the worker rotates the longitudinal connecting portion 20 to enable the stud to be screwed into the eye of the lifting ring, and installation of the single protection device can be completed.

As shown in fig. 1, in one possible implementation, a reinforcing rib is further included, and the reinforcing rib is connected between the top surface of the mounting portion 10 and the lower portion of the longitudinal connecting portion 20. Specifically, in the present embodiment, the reinforcing ribs may be triangular or right-angled trapezoidal.

The reinforcing rib plates are connected between the top surface of the mounting part 10 and the lower part of the longitudinal connecting part 20, so that the connecting strength between the longitudinal connecting part 20 and the mounting part 10 can be improved, the mounting part 10 such as flat iron is prevented from being broken after multiple uses, and the mounting part is difficult to play an effective protection role when a worker slides down.

In one possible implementation, the transformer work safety facility may include a plurality of guard cells. For example, four suspension ring holes are arranged on the top of the transformer, so that one set of transformer operation safety equipment can comprise four protection device single bodies.

A set of transformer operation safety facility includes a plurality of protector monomers, can all install on the transformer body a plurality of protector monomers once only. After the staff climbs the top of transformer body, need remove the operating position on the transformer body, only need with safety belt or protection rope be connected to the through-hole portion at different protector monomer tops can. The position of the working personnel can be conveniently switched, and the labor efficiency of the working personnel is improved.

The application provides a transformer, includes the transformer operation safety device in any kind of above-mentioned implementation. Wherein, the top of transformer body is equipped with the screw hole that is used for connecting the lug, and the free threaded connection spare of protector is connected in this screw hole.
