[0024] In this embodiment, the cable tray is quickly positioned on the installation center line of the top plate beam through the positioning component 1, and then the wire-releasing component 2 releases the center line according to the midpoint located by the positioning component 1. After the wire-releasing component 2 is at the installation end point of the cable tray, the released wire group is also fixed to further ensure that the wire group can be on the center line of the top plate beam, thereby ensuring that the installation of the cable tray will not be offset. The equipment is simple and effective, and workers can quickly get started using it, which greatly increases the efficiency of construction.

[0025] like Figure 1-5 As shown, based on Example 1, the utility model provides a technical solution: preferably, a slide groove 12 is opened on the inner top of the fixed frame 11, the inner wall of the slide groove 12 is fixedly connected with a slide rail 13, the surface of the slide rail 13 is slidably connected with a slider 14, and the top of the slider 14 is fixedly connected to the bottom of the connecting plate 17.

[0029] The following is a detailed description of the working principle of the cable tray positioning line laying auxiliary device.

[0030] like Figure 1-5As shown, the top of the fixing frame 11 is facing upwards and stuck on both sides of the top plate beam, and then the fixing screws 15 on both sides are synchronously rotated so that the pads at its ends fix the fixing frame 11 to the bottom of the top plate beam. According to the specific size of the cable tray and the width of the top plate beam, the spring rod 19 is pulled to make the positioning block 18 slide on the surface of the scale rod 16, so that the positioning block 18 can drive the bottom connecting plate 17 to be in the middle position of the top plate beam. During the displacement of the positioning block 18, the connecting plate 17 is assisted by the bottom slider 14 on the surface of the slide rail 13 to ensure that the movement of the positioning block 18 can maintain horizontal movement. After the positioning block 18 moves to the middle of the top plate beam on the scale rod 16, the spring rod 19 is released to prevent the positioning block 18 from moving further, thereby positioning the midpoint of the cable tray installation, thereby ensuring that the center point of the cable tray can always be installed in the middle of the top plate beam.
