[0020] The following is combined with Figure 1-4 This application is described in further detail.

[0021] The embodiment of the present application discloses a cable laying auxiliary device for a bridge in a narrow passage.

[0022] The cable laying auxiliary device for the bridge in the narrow passage of the present application is installed on multiple bridge steels on the same layer.

[0023] Reference Figure 1 and Figure 2 The cable laying auxiliary device for the bridge in a narrow channel includes a slide rail 1, two vertical rods 2, a slide roller 3, a cable traction machine and a lead wire 4. The slide rail 1 is horizontally arranged and fixedly arranged along the length direction of the bridge steel. The two vertical rods 2 are vertically arranged and are provided with rollers 21 through bearing rotation sleeves, and the upper ends of the vertical rods 2 are connected to slide along the length direction of the slide rail 1. The slide roller 3 is arranged parallel between the lower ends of the two vertical rods 2. The outer surface of the slide roller 3 is provided with a soft rubber protective sleeve. One end of the slide roller 3 is hinged to the lower end of one of the vertical rods 2, and the other end of the slide roller 3 is detachably connected to the lower end of the other vertical rod 2, so that the rotation axis of the slide roller 3 is vertically arranged. A clamping block 31 is welded at one end of the slide roller 3, and a clamping groove 32 for clamping the clamping block 31 is opened at the lower end of one of the vertical rods 2. One end of the lead wire 4 passes through each slide roller 3 and is connected to the end of the steel wire rope 6 of the cable traction machine, so that the plurality of slide rollers 3 can be driven by the lead wire 4 to move along the length direction of the slide rail 1 to the position where the cable needs to be laid.

[0024] Reference Figure 3 and Figure 4 In order to facilitate the installation and disassembly of the slide rail 1 in each auxiliary device on each bridge steel, a connecting component 5 is welded on the upper surface of the slide rail 1. The connecting component 5 includes a cross bar 51, a bracket 52, and a connecting rod 53. The bracket 52 is L-shaped, and one end of the bracket 52 is welded to one end of the cross bar 51, and the connecting rod 53 is hinged to the other end of the cross bar 51, so that the connecting rod 53, the cross bar 51 and the bracket 52 can form a rectangular frame. At the same time, the cross bar 51 is welded to the upper surface of the slide rail 1, and the bracket 52 can be erected on the bridge steel. A through groove 54 is opened at one end of the bracket 52 close to the connecting rod 53, and the through groove 54 is open. By rotating the connecting rod 53 upward, the upper end of the connecting rod 53 is penetrated into the through groove 54 and is threadedly connected with a nut 55, and the nut 55 is pressed against the upper surface of the bracket 52, so that the bracket 52 together with the slide rail 1 and the bridge steel are fixed.

[0025] Therefore, when laying the cable, the cable bracket can be placed at the head end of the bridge, and the cable traction machine can be placed at the end of the bridge. After that, a cable is placed on each sliding roller 3, and the lead wire 4 is passed through each sliding roller 3. At the same time, the end of the lead wire 4 is fixed to the end of the steel wire rope 6 of the cable traction machine, and the end of the steel wire rope 6 of the cable traction machine is fixed with a mesh sleeve 7 for connecting with the cable end. The mesh sleeve 7 is set on the cable end, so that the steel wire rope 6 of the cable traction machine can pull the cable, and the cable is moved to the laying position through the sliding roller 3. When the cable is pulled into place , so that the block 31 at one end of the sliding roller 3 can be separated from the slot 32 of the vertical rod 2 by rotating the sliding roller 3, so that the sliding roller 3 can rotate along the horizontal plane, so that the cable applied on the sliding roller 3 can slide down to the predetermined application position section by section, and at the same time, the cable traction machine is kept working continuously to ensure that the cable has a certain tension, thereby eliminating the cable slack margin, and repeating the above operation for the laying of the remaining cables, thereby improving the construction efficiency of the cable in the narrow channel by using the cable laying auxiliary device, reducing the cable collision and the occurrence of cable breakage and the like, which leads to a reduction in the service life of the cable.
