Problems solved by technology

[0003] When laying cables on the tunnel cable bridge, at the initial stage of construction, due to the uneven ground and top of the tunnel, and in the prior art, only support frames are laid at both ends of the tunnel, due to the heavy weight of the longer cables, the supporting effect of the cables Poor, the cable in some areas hangs down to the middle of the tunnel, occupying the working space of the tunnel, and the motor tractor cannot be used. Manual traction is completely used, the laying speed is slow, the labor intensity is high, and the cable is easy to wear and tear. During the traction process of the cable In the process, due to the incorrect direction of force, it is easy to cause the collapse of the cable bridge and cause major damage accidents

Embodiment 1

[0029] Attached Figure 1-3 As shown, the cable tray laying device provided by the present application includes several support units distributed at intervals, and the distance between adjacent support units is 5-12 meters. Each support unit includes an upper support frame 1, a lower support frame 2, Fixed pulley 3 and motor, the motor is installed on the lower support frame 2, and the motor plays the role of traction cable, figure 1 The middle motor is not shown. The fixed pulley 3 is installed on the top of the upper support frame 1, and the fixed pulley is connected with the upper support frame in rotation. There is a hole between the fixed pulley and the upper support frame, and the cable passes through the hole. At the same time, the fixed pulley plays a role in positioning the cable. The support unit supports the cable, and can prevent the cable from falling due to gravity. The upper support frame 1 is installed on the lower support frame 2, and the height between the...

Embodiment 2

[0037] In order to realize the height adjustment between the upper support frame and the lower support frame, the inventor made the following improvements on the basis of Embodiment 1, as attached Figure 4 As shown, in this embodiment, the upper support frame 1 includes a first support sleeve 8, the lower support frame 2 includes a first support rod 9, and the first support sleeve 8 is provided with internal threads, so The first support rod 9 is provided with an external thread compatible with the internal thread. Turn one of the upper support frame and the lower support frame to adjust the distance between the two.

Embodiment 3

[0039] In order to realize the height adjustment between the upper support frame and the lower support frame, the inventor made the following improvements on the basis of Embodiment 1, as attached Figure 5 As shown, the upper support frame 1 includes a second support sleeve 10, the lower support frame 2 includes a second support rod 11, the second support sleeve 10 is provided with locking bolts, and the second support The rod 11 is provided with several threaded holes adapted to the locking bolts, and the threaded holes are distributed at intervals along the height direction of the upper support frame or the lower support frame. The distance between the upper support frame and the lower support frame can be adjusted by inserting locking bolts into threaded holes at different positions.

[0040] The cable tray laying device provided by this application is suitable for the laying of cables in tunnels. The laying efficiency is high. The upper support frame and the lower support...

Abstract

The invention provides a cable bridge laying device, which relates to the technical field of cable laying. The device comprises a plurality of supporting units which are distributed at intervals; eachsupporting unit comprises an upper supporting frame, a lower supporting frame, a fixed pulley and a motor; the motor is mounted on the lower supporting frame; the fixed pulley is mounted at the top of the upper supporting frame; the upper supporting frame is mounted on the lower supporting frame; the height between the upper supporting frame and the lower supporting frame is adjustable; every twoadjacent supporting units are connected through a guide rod, a plurality of guide units are arranged on each guide rod, each guide unit comprises a base and a guide wheel assembly, the bases are fixed to the guide rods, the guide wheel assemblies are hung on the bases, and the two ends of the guide rods are connected with the two adjacent upper supporting frames respectively. The problems of lowcable laying efficiency and poor cable supporting effect in the prior art are solved, and the cable laying speed and laying safety in the tunnel are improved.

Description

technical field [0001] The present application relates to the technical field of cable laying, in particular to a cable bridge laying device. Background technique [0002] Cable trays are used for cable laying, which are divided into trough type, tray type, ladder frame type, grid type and other structures, and are composed of brackets, supporting arms and installation accessories. The bridge frame in the building can be erected independently, or it can be attached to various buildings and pipe gallery supports. [0003] When laying cables on the tunnel cable bridge, at the initial stage of construction, due to the uneven ground and top of the tunnel, and in the prior art, only support frames are laid at both ends of the tunnel, due to the heavy weight of the longer cables, the supporting effect of the cables Poor, the cable in some areas hangs down to the middle of the tunnel, occupying the working space of the tunnel, and the motor tractor cannot be used. Manual traction ...
