[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] like Figure 1-3As shown, a cable tray wiring device includes a cable tray 7. The top of the cable tray 7 is adjustablely connected to a lower support 6 via a second screw 502. The top of the lower support 6 is fixedly connected to an upper support 2. A driven clamping roller 302 is rotatably provided on the top side of the upper support 2. An active clamping roller 301 is rotatably provided on the bottom side of the upper support 2 in match with the driven clamping roller 302. The adjusting shaft 201 of the driven clamping roller 302 extends out of the outer side of the upper support 2 and is vertically connected to a spring 402. The spring 402 and the top of the lower support 6 are abutted together.

[0021] The second screw 502 is inserted through the end of the lower bracket 6. A second adjusting nut 501 is rotatably provided on one side of the second screw 502. A clamping plate 503 is fixedly connected to the other side of the second screw 502, and the clamping plate 503 and the cable tray 7 are abutted together.

[0022] The bottom side of the upper support 2 is connected to the rotating shaft 303 via the bearing seat 304. The active clamping roller 301 is sleeved on the outside of the rotating shaft 303. The rotating shaft 303 is also connected to the drive motor 1 via the coupling 101.

[0023] The top side of the upper bracket 2 has a first elongated hole 203 and the other side of the top of the upper bracket 2 has a second elongated hole 204. One end of the adjusting shaft 201 is fixedly installed in the first elongated hole 203, and the other end of the adjusting shaft 201 passes through the second elongated hole 204. The adjusting shaft 201 extends out of the outside of the second elongated hole 204 and is vertically threaded to a first screw 403. A first adjusting nut 401 is rotatably installed on the first screw 403, and a spring 402 is also fixedly connected to the bottom of the first screw 403.

[0024] The inner side of the upper bracket 2 is configured as a cable outlet groove 202.

[0025] Both the driven clamping roller 302 and the driving clamping roller 301 are provided with rubber conveying grooves 305 on their outer walls.

[0026] In practical application, this utility model serves as a practical small power tool. Driven by a drive motor 1, the active clamping roller 301 rotates, dragging the cable forward to the next cable tray wiring device. Simultaneously, rotating the first adjusting nut 401 adjusts the clamping of the driven clamping roller 302 and the active clamping roller 301, ensuring the cable is clamped securely without being too tight and damaging, or too loose and slipping. The cable end passes through suitable rubber grooves 305 on the driven and active clamping rollers 302 and 301, transporting the cable end to the next cable tray wiring device while the equipment is running. After the cable is laid, the cable tray wiring device is released. The first adjusting nut 401 is used to remove the cable from the cable outlet gap opened on the side of the upper bracket 2. Finally, the cable is placed on the cable tray, and then the device is removed. This structure can be arranged in multiple places along the cable tray 7 in the cable laying of new or expanded projects, realizing the dragging and laying of the auxiliary cable of the drive motor 1. It effectively saves labor costs and greatly improves the convenience and efficiency of the wiring operation. It solves the problem that in electrical engineering wiring operations, large-diameter cables are generally laid by dragging them manually, which usually leads to time-consuming and laborious wiring operations and ultimately affects the overall efficiency of the wiring operation. Therefore, this device has good practicality.
