Description

Technical Field

[0001] The utility model relates to the technical field of cable construction auxiliary devices, in particular to a bridge frame embedded cable laying auxiliary device. Background Art

[0002] In the construction of 10kV power distribution network, it is a common construction content to lay 10kV high-voltage cables in power pipe corridors or trenches. During the construction process, the new cable first enters the cable pipe through the cable well. In the current low-voltage industry expansion construction process, cable-free pulleys and other devices are often used for construction. During the construction process, iron rods are used to fix the bridge openings and corners to isolate the contact between the cable and the bridge and prevent the sharp surface of the bridge from easily scratching the cable. However, this method of fixing with iron rods will lead to problems such as insufficient cable stability, insufficient lateral movement protection, lack of flexibility in height adjustment, and may cause cable damage. Utility Model Content

[0003] The utility model aims to provide a bridge embedded cable laying auxiliary device to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bridge embedded cable laying device, comprising an embedded cylinder, the embedded cylinder is provided with an embedded groove along the length direction, the embedded cylinder is embedded on the groove side of the overhead cable duct through the embedded groove, and the embedded cylinder is provided with two fixing rods for fixing the embedded cylinder.

[0005] Preferably, the fixing rod is a telescopic fixing rod.

[0006] Preferably, a protective cover is provided on the fixing rod.

[0007] Preferably, a pulley bracket is provided between the two fixing rods, and a pulley is provided on the pulley bracket.

[0008] Preferably, the opening of the embedded groove gradually expands, and an elastic clamping device is provided inside one end of the embedded groove with a large opening, and the elastic clamping device includes a telescopic plate assembly and a spring plate assembly, and the telescopic plate assembly and the spring plate assembly are distributed on both sides of the center line of the embedded groove, and the spring plate assembly includes a first clamping plate and a spring connected to the spring plate, and the other end of the spring is fixed to the inner wall of the embedded tube; the telescopic plate assembly includes a second clamping plate, a fixing plate and a bolt, and a through hole is provided on the corresponding side of the embedded tube, and the fixing plate is provided with a screw hole, and the free end of the bolt is fixedly connected to the fixing plate through the corresponding through hole and screw hole.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] When the utility model needs to pass through the top surface of the trough side of the overhead cable trough and change direction during the overhead cable trough laying process, since the trough side is relatively thin and the contact area with the cable is small, when the cable moves from the top, it may cause resistance and damage to the surface of the cable. However, when the bridge frame embedded cable releasing device provided by the utility model is arranged on the trough side, the cable will move from the surface of the embedded cylinder. Since the surface of the embedded cylinder is arc-shaped and the contact area between the cable and the surface of the embedded cylinder is increased, when the cable is pulled, not only labor is saved, but also the surface of the cable will not be damaged.

DETAILED DESCRIPTION

[0018] The technical solution in one embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] See also Figure 1-6 :

[0020] Embodiment 1:

[0021] A bridge embedded cable laying device 1 comprises an embedding cylinder 11, wherein the embedding cylinder 11 is provided with an embedding groove 111 along the length direction, and the embedding cylinder 11 is embedded in the slot side of the overhead cable trough 2 through the embedding groove 111, and the embedding cylinder 11 is provided with two fixing rods 12 for fixing the embedding cylinder 11. In the process of laying the cable overhead, when the cable needs to pass through the top surface of the slot side of the overhead cable trough 2 and needs to change direction, since the slot side is relatively thin and the contact area with the cable is small, when the cable moves from the top, it may cause resistance and damage to the surface of the cable. However, when the bridge embedded cable laying device 1 provided by the utility model is arranged on the slot side, the cable will move from the surface of the embedding cylinder 11. Since the surface of the embedding cylinder 11 is arc-shaped, and the contact area between the cable and the surface of the embedding cylinder 11 is increased, when pulling the cable, it is not only labor-saving, but also does not cause damage to the surface of the cable.

[0022] In order to facilitate the installation of the embedding tube 11 , the fixing rod 12 is configured as a retractable fixing rod 12 .

[0023] When the cable moves and changes direction, it is possible that the cable contacts the surface of the fixing rod 12 , and therefore, a protective cover 13 is provided on the fixing rod 12 to protect the surface of the cable.

[0024] Embodiment 2:

[0025] Based on the first embodiment, in order to save more effort when pulling the cable to change direction (such as bending), a pulley 132 bracket 131 is provided between the two fixing rods 12, and a pulley 132 is provided on the pulley 132 bracket 131.

[0026] Embodiment 3:

[0027] This embodiment is based on the second embodiment. Since the position of the overhead cable trough 2 and the initial direction of the cable passing through the overhead cable trough 2 are not fixed, in order to adapt to the position of the overhead cable trough 2 and the initial direction of the cable passing through the overhead cable trough 2, it is convenient to adjust the direction of the pulley 132 to be closer to the initial direction of the cable passing through the overhead cable trough 2, so as to facilitate the guidance through the pulley 132 and save effort. The opening of the embedded groove 111 is gradually expanded, and an elastic clamping device is provided inside one end of the embedded groove with a large opening. The elastic clamping device includes a telescopic plate assembly and a spring plate assembly. The telescopic plate assembly and the spring plate assembly are distributed on both sides of the center line of the embedded groove 111, and the spring 1422 plate assembly includes a first clamping plate 1421 and a spring 1422 connected to the spring 1422 plate, and the other end of the spring 1422 is fixed to the inner wall of the embedded cylinder 11; the telescopic plate assembly includes a second clamping plate 1411, a fixing plate 1412 and a bolt 1413, and a through hole is provided on the corresponding side of the embedded cylinder 11, and the fixing plate 1412 is provided with a screw hole, and the free end of the bolt 1413 is fixedly connected to the fixing plate 1412 through the corresponding through hole and screw hole. When in use, the embedding groove 111 of the embedding tube 11 is used, and the groove side is clamped between the first clamping plate 1421 and the second clamping plate 1411 by retreating the bolt 1413. The initial direction of the cable passing through the overhead cable duct 2 is estimated, and the position of the second clamping plate 1411 is adjusted by the bolt 1413 to offset the embedding tube 11 to adjust the direction of the pulley 132 to be closer to the initial direction of the cable passing through the overhead cable duct 2, so as to facilitate the guidance through the pulley 132 and save effort.
