Detailed Description

To make the objects, technical solutions and advantages of the present disclosure more apparent, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

In the disclosed embodiment, power cables are used in the power system backbone to transmit and distribute high power electrical energy, and control cables transmit electrical energy from distribution points of the power system directly to power connections of various consumer appliances. The rated voltage of the power cable is generally 0.6/1kV or more, and the rated voltage of the control cable is mainly 450/750V.

In the cable laying construction, for example, when laying cables in a raceway, since the raceway has a limited space and a long length, there are the following requirements for laying a large number of cables.

Firstly, the cables need to be placed in the wire grooves neatly.

And secondly, when the power cable and the control cable are laid in the same wire slot, the power cable and the control cable need to be separated.

And thirdly, the power cables are relatively fixed.

Based on the above requirements, the disclosed embodiments provide a cable trough.

Fig. 1 is a schematic structural diagram of a cable duct provided in an embodiment of the present disclosure. Referring to fig. 1, the cable duct includes: the device comprises a tank body 1, a suspension bracket 2 and a fixing block 3.

The suspension bracket 2 is transversely arranged on the notch 11 of the tank body 1.

The fixing block 3 is located in the tank body 1 and has a gap with the tank wall of the tank body 1, the fixing block 3 comprises an upper clamping groove 31 and a lower clamping groove 32 matched with the upper clamping groove 31, the upper clamping groove 31 and the lower clamping groove 32 are detachably connected, an installation channel used for accommodating a first cable is formed between the upper clamping groove 31 and the lower clamping groove 32, a suspension arm 311 is arranged on the upper clamping groove 31, and the suspension arm 311 is movably connected with the suspension frame 2.

In the embodiment of the disclosure, the cable trough comprises a trough body 1, a suspension bracket 2 and a fixing block 3, the suspension bracket 2 is transversely arranged on a notch 11 of the trough body 1, the fixing block 3 is positioned in the trough body 1, the fixing block 3 comprises an upper clamping groove 31 and a lower clamping groove 32 matched with the upper clamping groove 31, the upper clamping groove 31 and the lower clamping groove 32 are detachably connected, and an installation channel for accommodating a first cable is formed between the upper clamping groove 31 and the lower clamping groove 32; the first cable can be a power cable, and because the power cable is bound between the upper clamping groove 31 and the lower clamping groove 32, compared with a plastic binding belt, the contact area between the clamping groove (the upper clamping groove 31 and the lower clamping groove 32) type fixing block 3 and the power cable is larger, so that the binding is firmer, and the power cable is not easy to be separated from the binding of the clamping groove type fixing block 3 during jumping and drives the clamping groove type fixing block 3 to move together; because the upper clamping groove 31 is provided with the suspension arm 311, the suspension arm 311 is movably connected with the suspension frame 2, and a gap exists between the fixed block 3 and the groove wall of the groove body 1, in this way, when the power cable jumps and drives the clamping groove type fixed block 3 to move together, the suspension arm 311 can drive the clamping groove type fixed block 3 to move (such as swing) relative to the suspension frame 2, so that the movement caused by jumping is released until the clamping groove type fixed block 3 is static for the suspension frame 2, thereby avoiding the phenomenon that the cable is abraded by a binding belt due to strong binding for inhibiting shaking, and protecting the cable.

The first cable may be a power cable.

Wherein the hanger 2 is parallel to the width direction (W in fig. 1) of the tank 1.

Fig. 2 is a schematic structural diagram of a suspension bracket provided in the embodiment of the present disclosure. Illustratively, referring to fig. 2, the suspension bracket 2 is provided with a mounting hole 21.

Correspondingly, the suspension arm 311 is movably inserted into the mounting hole 21, a ball 312 matched with the mounting hole 21 is arranged at one end of the suspension arm 311, and the suspension arm 311 is located between the upper clamping groove 31 and the ball 312.

The ball 312 is designed such that the suspension arm 311 can rotate relative to the mounting hole 21. When the power cable jumps and drives the slot-type fixing block 3 to move together, the movement in the direction perpendicular to the suspension bracket 2 will cause the suspension arm 311 to move in the direction perpendicular to the suspension bracket 2 through the mounting hole 21; since the ball 312 can rotate with the mounting hole 21 as a ball seat, the movement in the direction parallel to the suspension bracket 2 causes the suspension arm 311 to move in the direction parallel to the suspension bracket 2 via the ball 312, thereby completely releasing the movement caused by the bounce.

Illustratively, referring to fig. 2, the suspension bracket 2 is further provided with a mounting groove 22, the mounting groove 22 is communicated with the mounting hole 21, the groove width of the mounting groove 22 is smaller than the bore diameter of the mounting hole 21, the groove width of the mounting groove 22 is the same as the outer diameter of the suspension arm 311, and the length direction of the mounting groove 22 is perpendicular to the length direction of the suspension bracket 2.

The mounting groove 22 is designed to remove and mount the suspension arm 311 into the mounting hole 21. Since the groove width of the mounting groove 22 is smaller than the bore diameter of the mounting hole 21 and the groove width of the mounting groove 22 is the same as the outer diameter of the suspension arm 311, the length direction of the mounting groove 22 is perpendicular to the length direction of the suspension bracket 2, that is, the length direction of the mounting groove 22 is the same as the length direction of the tank body 1 (the length direction is perpendicular to the width direction W), the suspension arm 311 is not easily moved from the mounting hole 21 into the mounting groove 22 and falls off from the suspension bracket 2.

Alternatively, the hanger 2 may be of channel-like construction and overlie the channel 11.

Wherein, the fixed block 3 is hung on the hanging bracket 2 through the hanging arm 311.

Alternatively, the upper card slot 31 and the lower card slot 32 may be connected by screws.

Fig. 3 is a schematic structural diagram of a fixing block provided in the embodiment of the present disclosure, and fig. 4 is a schematic structural diagram of an upper card slot provided in the embodiment of the present disclosure. Illustratively, referring to fig. 3 and 4, the upper card slot 31 is provided with a first connection boss 313, and the suspension arm 311 and the first connection boss 313 are located on opposite sides of the upper card slot 31.

Fig. 5 and 6 are schematic structural diagrams of a lower card slot provided in an embodiment of the present disclosure. For example, referring to fig. 3, 5 and 6, the lower card slot 32 is provided with a first connection groove 321 which is matched with the first connection boss 313.

The first connection boss 313 is disposed in the first connection groove 321 to detachably connect the upper and lower clamping grooves 31 and 32, and a boss-groove connection is more convenient to install than a plastic band and a screw, and also prevents a connection effect from being different for constructors.

Illustratively, the number of the fixed blocks 3 is three or more, and each fixed block 3 is arranged on the suspension bracket 2 at regular intervals.

Correspondingly, a second connecting boss 314 is arranged on one side wall of the upper clamping groove 31 in each fixing block 3, the length direction of the second connecting boss 314 is parallel to the length direction of the suspension frame 2, a second connecting groove 315 is arranged on the other side wall of the upper clamping groove 31, the second connecting boss 314 is opposite to the second connecting groove 315, and the second connecting boss 314 of one fixing block 3 in two adjacent fixing blocks 3 is matched with the second connecting groove 315 of the other fixing block 3.

Correspondingly, the suspension bracket 2 is provided with three or more mounting holes 21 and mounting grooves 22, and the mounting holes 21 and the mounting grooves 22 are respectively in one-to-one correspondence with the fixing blocks 3. Thus, three or more fixing blocks 3 are suspended below the suspension bracket 2 at regular intervals.

Illustratively, the groove bottom of the second connection groove 315 is provided with a spring 316, and when the second connection groove 315 is provided with a second connection boss 314 disposed therein, the spring 316 is sandwiched between the groove bottom of the second connection groove 315 and the second connection boss 314.

When a certain first cable has electrical stress jitter, the jitter in the left-right direction is transmitted to the second connecting groove 315 of the adjacent fixed block 3 through the second connecting boss 314, and the kinetic energy is absorbed by the spring 316 in the groove. And the shaking in the up-and-down direction is realized, firstly, due to the existence of the second connecting boss 314, the adjacent fixing blocks 3 are integrated, so that the shaking amplitude can be inhibited, in addition, because the ball head 312 at one end of the suspension arm 311 does not restrict the cable in the up-and-down direction, the cable is allowed to shake up and down, after the shaking disappears, due to the shape characteristics of the ball head 312, the fixing blocks 3 can automatically fall back into the mounting hole 21 of the suspension groove, and thus, the phenomenon that the cable is worn by a binding belt due to the strong binding for inhibiting the shaking is avoided.

In assembly, the hanger 2 is placed on top of the body 1 of the raceway. The hanger 2 is provided with a plurality of parallel mounting slots 22. The suspension arm 311 of the upper card slot 31 is inserted into the suspension bracket 2 from the opening of the mounting groove 22, because the mounting groove 22 is a straight groove with a smaller opening, the end of the mounting groove is a mounting hole 21, and the mounting hole 21 is a round hole with a larger diameter (but smaller than the diameter of the top ball 312 of the suspension arm 311), the suspension arm 311 of the upper card slot 31 falls after being completely inserted into the mounting hole 21 and is clamped on the mounting hole 21. The upper card slot 31 and the lower card slot 32 are then connected and the power cable is disposed between the upper card slot 31 and the lower card slot 32. After each fixing block 3 is hung in the mounting hole 21, the second connecting boss 314 arranged on the left or right of each fixing block 3 is inserted into the second connecting groove 315 of the adjacent fixing block 3, so that the connection of the adjacent fixing blocks 3 is completed.

It should be noted that, because the length of the trunking can be long, a plurality of suspension brackets 2 can be arranged on the trunking body 1 at intervals, the number of the fixing blocks 3 on each suspension bracket 2 is the same, the same first cable can be bound through the plurality of fixing blocks 3, and the fixing blocks 3 binding the same first cable are positioned on the same straight line.

Exemplarily, a mounting channel for accommodating a second cable is formed between the fixing block 3 and the groove bottom of the groove body 1 (fig. 1, a horizontal filling area).

Optionally, the second cable is a control cable.

Like this, the power cable hangs in the top of control cable to keep apart through fixed block 3, realized the isolation in space between power cable and the control cable, adaptation power cable and control cable can install in same wire casing.

Alternatively, the tank body 1 and the suspension bracket 2 may be made of metal (e.g., steel), and the fixing block 3 may be made of nylon.

Fig. 7 is a schematic structural diagram of a cable duct after a fixing block and a suspension bracket are removed according to an embodiment of the disclosure. Exemplarily, referring to fig. 7, the cable raceway further comprises a stranding rod 4.

The stranded cable rod 4 is detachably transversely inserted into the groove wall of the groove body 1 in a penetrating mode, the stranded cable rod 4 is rotatably connected with the groove wall of the groove body 1, a mooring bollard 42 is arranged on the stranded cable rod 4, and the mooring bollard 42 is located in the groove body 1.

Because the cable has certain gravity, the manual work is dragged and is more laborious and time-consuming when laying. The purpose of the wire rod 4 is to accelerate the speed of laying the cable. Can be through haulage rope (lighter than the cable) with the one end system of cable on bollard 42, rotatory stranded cable pole 4, stranded cable pole 4 will drag the cable through the haulage rope, improves the speed of laying of cable.

The structure of the stranded cable rod 4 and the connection mode of the stranded cable rod 4 and the tank body 1 are described below.

Referring to fig. 12, the other end of the swing arm 13 is provided with a first positioning hole 14, and the wall of the groove is provided with a second positioning hole 15 matching with the first positioning hole 14. The swing arm 13 is provided with a semicircular notch, and the semicircular notch and the bottom of the guide groove 12 form a hole K for the twisted cable rod 4 to penetrate through.

The swing arm 13 is hinged with the groove wall, and one end of the swing arm 13 can rotate freely. When the swing arm 13 rotates to the horizontal position, the first positioning hole 14 on the swing arm 13 is overlapped with the second positioning hole 15 on the groove wall, and then the pin is inserted into the first positioning hole 14 and the second positioning hole 15, so that the swing arm 13 can be fixed at the angle. At this time, the semicircular notch on the swing arm 13 and the semicircle at the bottom of the guide slot 12 together form a hole (circular hole) for the insertion of the twisted cable rod 4.

The rod body 41 of the mooring rod 4 may be in the shape of a round rod, the diameter of which is slightly smaller than the inner diameter of the hole through which the mooring rod 4 is inserted. In this way, the cable bar 4 can be moved from the slot 11 of the guide slot 12 into the hole through which the cable bar 4 is inserted.

The suspension bracket 2 and the fixed block 3 can be arranged in the spliced wire casing to suspend and install the power cable. Before installing the power cables and the control cables, the corresponding cables are drawn into the trunking and arranged in order by the bollards 42.

FIG. 16 is a schematic illustration of cable drag provided by embodiments of the present disclosure. The following briefly describes the cable dragging process with reference to fig. 16.

The first step is as follows: firstly, the stranded cable rod is put into the bottom of the guide groove from the tail end of the wire groove.

Two stop arms of the cable twisting rod are positioned outside the wire slot, the swing arm is operated to the horizontal position until a first positioning hole on the swing arm is superposed with a second positioning hole on the side wall of the wire slot, and then the pin is inserted, at the moment, the cable twisting rod is limited in a circular hole formed by the swing arm and the tail end of the guide slot together, and only can rotate. And because the two ends of the stranded cable rod are provided with the stop arms, the stranded cable rod cannot be axially separated.

The second step is that: one end of the input shaft is inserted into the blind hole at the end of the stranded cable rod.

The third step: referring to fig. 16, a cable D or cable bundle to be hauled is placed at the beginning of a raceway arrangement, the end of the cable D is tied with one end of a pull rope (thin wire rope or nylon rope) Q, the other end of the pull rope Q is attached to a bollard 41 of the mooring rod 4.

And fourthly, connecting the clamping part of the electric hand drill (or other tools such as a wind drill) with the hexagonal end of the input shaft, then operating the input shaft to rotate, enabling the stranded cable rod to rotate, and enabling the cable to rapidly move through the rotating stranded cable rod, so that the cable or the cable bundle can be dragged to the terminal point from the starting point of the wire groove.

The design of the stranded cable rod has the following advantages:

1. the stranded cable rod has simple structure and convenient use;

2. the cable is towed by using the self-carried stranded cable rod, manual construction is not needed, meanwhile, a special towing machine is not needed, and cost is effectively saved.

3. The groove body can be designed in a modular structure, the length can be cut at will according to actual use working conditions, and the working efficiency is effectively improved.

4. The external power input end of the input shaft is in a hexagonal shape, and the universal interface is applicable to various conventional rotary power sources such as electric hand drills, wind power drills and the like, and is wide in application scene.

The above description is intended to be exemplary only and not to limit the present disclosure, and any modification, equivalent replacement, or improvement made without departing from the spirit and scope of the present disclosure is to be considered as the same as the present disclosure.
