It has the advantages of being convenient for winding up cables and cleaning and protecting cables. When a worker takes a tool, the servo motor is turned on according to the direction, and the electric telescopic column 401 is repeatedly turned on. The electric telescopic column 401 drives the fixed disk 402 to move left and right, and then drives the winding roller 404 to move left and right, and the cable is gradually wound around the arc base 405 and the outside of the winding roller 404.

[0040] The fan is turned on regularly, and the wind in the fan moves to the outside of the annular groove 411 through the vents to supply air to the cable and assist in heat dissipation.

It has the advantages of being easy to control the position of the user and providing safety reminders. Before using the equipment, the electric push rod 601 is turned on, and the electric push rod 601 drives the top plate 602 above to move upward, and at the same time, the telescopic plate 603 can be stretched upward to protect the worker outside. The worker manually puts the safety helmet on his head. After starting work, the worker starts to move inside the equipment, driving the triangular plate 6063 on the top of the safety helmet to move, and then driving the spring 6062 and the sliding plate 6061 above the triangular plate 6063 to move. The sliding plate 6061 slides inside the slide 605. When the triangular plate 6063 hits the soft rod 6065 at the bottom of the inclined plate 607 outward, it cannot move outward, prompting the worker that the movement is about to exceed the range, so as to protect the worker's safety.

[0045] The transport mechanism 8 includes a horizontal column 801, three horizontal columns 801 are provided, the bottom of the horizontal column 801 is fixedly connected with a connecting vertical plate 802, two connecting vertical plates 802 are provided, the outside of the connecting vertical plate 802 is fixedly connected with an electric telescopic rod 803, and the horizontal column 801 is fixedly connected to the outside of the fixed platform 2.

After the worker enters the equipment, the second electric telescopic rod 805 is turned on until the second electric telescopic rod 805 is clamped and connected to the inside of the clamping circular hole 9 to protect the worker. Then the tools used for work can be placed inside the transport box 804, the cables can be placed outside the transport box 804 through the arc groove, and the tools are manually pressed until the back side of the tool fits on the outside of the suction disk 807. After the worker starts working, he can open the corresponding electric telescopic rod 803 according to the tools he needs to use. The electric telescopic rod 803 drives the transport box 804 to move forward. After the movement stops, the worker manually pulls the second clamping plate 810 outward, and the second clamping plate 810 drives the second spring 809 to move outward. At this time, the tools inside the transport box 804 can be manually pulled outward.

[0048] Working principle: Before using the equipment, the transport mechanism 8 is turned on, and the worker stands on the top of the bottom plate 1 and inside the enclosure 10, and turns on the second electric telescopic rod 805 until the second electric telescopic rod 805 is engaged and connected inside the locking circular hole 9 to protect the worker. Then the tools used for work can be placed inside the transport box 804, and the cables can be placed outside the transport box 804 through the arc groove, and the tools are manually pressed until the back side of the tools is attached to the outside of the suction plate 807. After the worker starts working, he can turn on the corresponding electric telescopic rod 803 according to the tools he needs to use, and the electric telescopic rod 803 drives the transport box 804 to move forward. After the movement stops, the worker manually pulls the second locking plate 810 outward, and the second locking plate 810 drives the second spring 809 to move outward. At this time, the tools inside the transport box 804 can be manually pulled outward.

[0049] Then, the protection mechanism 6 and the winding mechanism 4 are manually adjusted to wind up the cable and protect the worker. When the worker takes the tool, the servo motor is turned on according to the direction, and the electric telescopic column 401 is repeatedly turned on. The electric telescopic column 401 drives the fixed plate 402 to move left and right, and then drives the winding roller 404 to move left and right. The cable is gradually wound around the arc base 405 and the outside of the winding roller 404.

[0050] The fan is turned on regularly, and the wind in the fan moves to the outside of the annular groove 411 through the vents to supply air to the cable and assist in heat dissipation. The second electric telescopic column 408 is turned on regularly and repeatedly, and the second electric telescopic column 408 drives the external fixed rod 409 to move back and forth repeatedly, thereby driving the brush head 410 at the bottom of the fixed rod 409 to move back and forth, cleaning the outer surface of the cable to prevent impurities from accumulating on the outer surface of the cable.

[0051] When the equipment is not in use, the second electric telescopic column 408 is turned on and the electric lifting plate 406 is turned off. The second electric telescopic column 408 drives the fixing rod 409 to move outward, and the electric lifting plate 406 drives the fixing rod 409 to move downward. The fixing rod 409 and the second electric telescopic column 408 fix the cable outside the winding roller 404 to prevent the cable from folding and curling at the bottom, or even tripping the workers.

[0052] Before using the equipment, turn on the electric push rod 601, which drives the top plate 602 to move upward, and at the same time can stretch the telescopic plate 603 upward to protect the worker from the outside. The worker manually puts the safety helmet on his head, and after starting work, the worker starts to move inside the equipment, driving the triangular plate 6063 on the top of the safety helmet to move, and then drives the spring 6062 and the sliding plate 6061 above the triangular plate 6063 to move. The sliding plate 6061 slides inside the slide 605. When the triangular plate 6063 hits the soft rod 6065 at the bottom of the inclined plate 607 outward, it cannot move outward, prompting the worker that the movement is about to exceed the range, so as to protect the worker's safety. At this time, the height control device can be turned on to transport the bottom plate 1 upward, so that the worker can move upward.
