[0021] The utility model provides an embodiment:

[0022] like Figures 1 to 3 As shown, an automatic wire-laying vehicle for electrified construction includes a flatbed vehicle 1, a lifting mechanism, a rotating mechanism and a cable loop 4;

[0023] The lifting mechanism includes a threaded rod 2.1, a threaded sleeve 2.2, a lifting motor 2.3, a bevel gear set 2.4, a transmission shaft 2.5, and a turntable 2.6. The turntable 2.6 is rotatably connected to the top of the threaded sleeve 2.2 through a bearing 2.7. The threaded rod 2.1 is threadedly connected in the threaded sleeve 2.2 and the lower end is fixedly connected to the transmission shaft 2.5. The lifting motor 2.3 arranged at the upper end of the flatbed truck 1 transmits power to the vertical transmission shaft 2.5 through the bevel gear set 2.4; the lifting motor 2.3, the bevel gear set 2.4 and the transmission shaft 2.5 are arranged at the upper end of the flatbed truck 1 through a bridge frame 2.12.

[0024] The rotating mechanism includes a support platform 3.1, a rotating motor 3.2, a transmission belt 3.3, a pulley I3.4, a pulley II3.5 and a telescopic rod 3.6. The support platform 3.1 is rotatably connected to the outer wall of the transmission shaft 2.5, and the outer wall of the transmission shaft 2.5 has a groove structure that is rotatably matched with the support platform 3.1; the pulley II3.5 is rotatably connected to the outer wall of the support platform 3.1, and the support platform 3.1 has a groove structure that is rotatably matched with the pulley II3.5; a plurality of telescopic rods 3.6 are arranged in a circular array and the two ends are respectively connected to the pulley II3.5 and the turntable 2.6; the output shaft of the rotating motor 3.2 arranged at the upper end of the flatbed vehicle 1 is fixedly connected to the pulley I3.4, and the pulley I3.4 and the pulley II3.5 are transmitted through the transmission belt 3.3; the pulley I3.4 and the pulley II3.5 are located on the same horizontal line to ensure the stability of the transmission;

[0025] A sleeve rod 2.8 is arranged at the upper end of the turntable 2.6, and the cable loop 4 is movably sleeved on the sleeve rod 2.8; a threaded block 2.11 is threadedly connected to the upper end of the sleeve rod 2.8, and the threaded block 2.11 is located above the cable loop 4.

[0026] In this embodiment, a wheel body 1.1 is provided at the bottom center position of the flatbed cart 1, a traction frame 1.2 is provided at the end of the flatbed cart 1, a support rod 1.3 is fixed through the front end of the flatbed cart 1, and a shock-absorbing spring 1.4 is provided on the outer side of the support rod 1.3; a shock-absorbing plate 1.5 is fixed to the lower end of the shock-absorbing spring 1.4, and the upper end is fixedly connected to the lower end of the flatbed cart 1.

[0027] The outer wall of the threaded sleeve 2.2 is slidably connected with a guide sleeve 2.9, which is fixedly connected to the upper end of the support platform 3.1 via a limit rod 2.10. When the threaded sleeve 2.2 is always in a vertical state, it prevents the threaded sleeve 2.2 from shifting when moving up and down, causing the lifting mechanism to tilt and affecting the subsequent wire laying work.

[0028] Specific working principle:

[0029] Before using the wire-laying vehicle, the operator needs to place the cable loop 4. The lifting mechanism can be used to conveniently and labor-savingly place the cable loop 4 on the flatbed vehicle 1:

[0030] Start the lifting motor 2.3, the bevel gear set 2.4 drives the transmission shaft 2.5 to rotate, and then the threaded rod 2.1 rotates relative to the threaded sleeve 2.2, and the threaded sleeve 2.2 moves up and down along the threaded rod 2.1. When the threaded sleeve 2.2 moves downward, it drives the turntable 2.6 connected to the top of the turntable 2.6 by the bearing to descend, and compresses the telescopic rod 3.6, at this time, the cable ring 4 can be easily placed on the top of the turntable 2.6;

[0031] Before placing the cable loop 4, remove the thread block 2.11, and place the cable loop 4 on the top of the turntable 2.6 through the sleeve rod 2.8. At this time, install the thread block 2.11 so that the cable loop 4 will not deviate when moving, affecting the wire release effect.

[0032] The rotating motor 3.2 is started, and the pulley II3.5 is driven to rotate through the belt transmission mechanism, and the turntable 2.6 rotates accordingly. The rotation of the turntable 2.6 makes the cable ring 4 rotate more flexibly, the wire-releasing resistance becomes smaller, the wire-releasing progress is accelerated, and the wire-releasing efficiency is improved.

[0033] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model shall be based on the protection scope of the claims.
