The cross brace 112 is disposed between the two support arms 111 at intervals along the length direction of the support arms 111, and a plurality of through holes 1121 are disposed at intervals along the length direction of the cross brace 112.
Referring to fig. 1 and 2, the cable pulling and releasing auxiliary device 12 is detachably mounted between the two cross braces 112 of the cable tray 11, and the cable pulling and releasing auxiliary device 12 of the present embodiment includes a bracket 121 and two rollers 122, and the two rollers 122 are detachably mounted on the bracket 121 at intervals along the length direction of the bracket 121. In other preferred embodiments, the cable pull/pay-off aid 12 may include a plurality of rollers 122, and the number of the rollers 122 may be determined according to the length of the cable to be pulled and paid off and the amount of the pulling and paying off work. Meanwhile, in the actual cable pulling and releasing operation, the roller 122 with a proper size can be selected according to the width of the cable bracket 11 and the diameter of the pulled and released cable.
The bracket 121 includes a pair of support members 124 arranged in parallel, and the space between the support members 124 is smaller than the width of the cable tray 11. The supporting member 124 includes a supporting plate 1241, a bottom plate 1242 vertically connected to the supporting plate 1241, and two connecting plates 1243 formed by bending two ends of the bottom plate 1242 upward respectively. The three can integrated into one piece, also can welded connection, and backup pad 1241 is connected with bottom plate 1242 is perpendicular, for support piece 124 provides great support strength, has guaranteed that the cable is drawn and has been put auxiliary device 12 and when drawing and put the cable thick and the great cable of bundling weight non-deformable, can normally work, reduces the risk of wearing and tearing cable.
In order to detachably mount the supporting member 124 on the cross brace 112, the two connecting plates 1243 are respectively provided with a mounting portion 1244, the mounting portion 1244 of this embodiment is a screw hole, and a bolt passes through the mounting portion 1244 and the through hole 1121 of the cross brace 112, so as to mount the bracket 121 on the cross brace 112. The bolt fastening connection mode not only enables the support 121 to be stably connected to the cross brace 112, but also facilitates the installation and the disassembly of the cable pulling and releasing auxiliary device 12, and reduces the labor consumption. Preferably, the mounting portion 1244 is an oblong screw hole, the length direction of the oblong screw hole is perpendicular to the length direction of the support 124, so that the mounting portion 1244 corresponds to the through hole 1121 of the cross-brace 112, and the connecting plate 1243 and the cross-brace 112 are easily connected and fixed by the penetration of a bolt.
