[0040] It should be noted that when in use, the lifting platform is arranged at the construction site by driving the trolley 2, and then the auxiliary support assembly 6 is unfolded to firmly support the lifting platform at the construction site. Then, the remote control 8 is used to send a lifting instruction to the controller 7 to control the hydraulic cylinder 35 to drive the gantry frame 2 32 to lift along the gantry frame 1 31. During lifting, the steering wheel 1 361 is synchronously driven to lift and lower, and then the gantry frame 33 is driven to lift and lower along the gantry frame 2 32 through the chain 1 362. During lifting, the steering wheel 2 371 is driven to lift and lower, and then the gantry frame 4 34 is driven to lift and lower synchronously through the chain 2 372, thereby realizing the lifting of the entire lifting platform. After lifting, the self-locking assembly 38 is used for self-locking. Before lifting, the insulating ladders 52 at both ends are unfolded so that the staff can climb onto the insulating base 51. After climbing, the insulating ladders 52 are retracted and cooperated with the insulating guardrail 53 to realize high-altitude live work. The entire lifting and climbing is convenient, has lifting self-locking protection, and the lifting is very safe.

[0041] In the embodiments of the present invention, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The self-locking assembly 38 includes a rack plate 381 sequentially mounted on the four inner corners of the gantry 1 31, the gantry 2 32 and the gantry 3 33, and a locking member 382 sequentially mounted on the four inner corners of the gantry 2 32, the gantry 3 33 and the gantry 4 34;

[0042] The locking member 382 includes a vertical plate 3821 which is sequentially installed at the bottom ends of the four inner corners of gantry frame 2 32, gantry frame 33 and gantry frame 4 34. A transmission shaft 3822 is rotatably installed on the vertical plate 3821. A transmission gear 3823 is fixedly installed on the end of the transmission shaft 3822 facing outward. The transmission gear 3823 is engaged with the rack plate 381 on the same side. The other end of the transmission shaft 3822 is fixedly sleeved with a ratchet 3824. The vertical plate 3821 is rotatably installed with an arc-shaped stopper 3825 that cooperates with the ratchet 3824 to limit the position. A hydraulic rod 3826 is fixedly installed on the top of the vertical plate 3821. The telescopic end of the hydraulic rod 3826 faces downward and is fixedly installed with a limit plate 3827.

[0043] It should be noted that when the self-locking assembly 38 is used, the hydraulic rod 3826 is controlled to drive the limit plate 3827 away from the top of the arc-shaped stopper 3825 during lifting and lowering, so that the vertical plate 3821 drives the transmission gear 3823 to roll synchronously along the rack plate 381 when following the synchronous lifting and lowering. When rolling, the ratchet 3824 can also follow the rotation. Here, the arc-shaped stopper 3825 will not be automatically stuck due to the set arc and the teeth on both sides of the ratchet groove of the ratchet 3824, and can be toggled away from the ratchet groove to It will not restrict the ratchet 3824. After the lifting platform is adjusted, the hydraulic rod 3826 is controlled to extend, and the limit plate 3827 is blocked above the arc-shaped block 3825, limiting its upward rotation away from the ratchet groove, thereby achieving one-way locking of the ratchet 3824, thereby controlling the transmission shaft 3822 to stop rotation, and utilizing the transmission gear 3823 to engage with the rack plate 381 for self-locking. The one-way locking here is to limit its downward fall. When it is necessary to control the descent, the self-locking needs to be released. When it is necessary to rise, it can rise freely without releasing the self-locking.

[0044] In the embodiments of the present invention, please refer to Figure 1 and Figure 4 The insulating ladder 52 includes a slide bar 521 that slides with the slide groove 501 provided on the insulating base 51. An insulating ladder body 522 is fixedly mounted on the slide bar 521. A handrail 523 is mounted on the upper surface of the end of the insulating ladder body 522 that is away from the slide bar 521. A slot 502 is provided at the bottom of the end of the insulating ladder body 522 that is away from the slide bar 521. Stop rods 9 that are engaged with the slot 502 are mounted on both ends of the base plate 1 through brackets.

[0045] The length of the handrail 523 is half the length of the insulating ladder body 522 , and the insulating base 51 , the insulating ladder 52 and the insulating guardrail 53 are all made of epoxy resin material.

[0046] It should be noted that: in this way, the insulating ladder main body 522 can be slid and unfolded along the slide groove 501 using the sliding rod 521, and then rotated to engage the slot 502 with the blocking rod 9, so that it is convenient to use the insulating ladder main body 522 to climb to the insulating base 51 for operation. The entire platform is made of insulating material, which is convenient for live operations. After climbing, the insulating ladder main body 522 is inserted into the insulating base 51. After insertion, it can be locked using the locking bolt 511 set on the outside of the insulating base 51. After locking, the insulating ladder main body 522 exposed outside can be used as an extension platform to expand the range of the platform.

[0047] In the embodiments of the present invention, please refer to Figure 1 and Figure 4The auxiliary support assembly 6 comprises a rectangular tube 61 fixedly installed at the bottom of the base plate 1, and a rectangular rod 62 symmetrically inserted into the rectangular tube 61, wherein one end of the rectangular rod 62 away from the rectangular tube 61 is threadedly installed with a screw rod 63, the bottom end of the screw rod 63 is fixedly installed with a support disc 64, the top end of the screw rod 63 is fixedly installed with a hand wheel 65, a plurality of limiting holes 601 are uniformly formed in the rectangular rod 62, and the outer sides of the two ends of the rectangular tube 61 are threadedly installed with limiting screws 611 matched with the limiting holes 601;

[0048] It should be noted that: when the auxiliary support assembly 6 is used, when the lifting platform is dragged and placed to the construction position, the limiting of the limiting screw 611 is released, the rectangular rod 62 is pulled outwards to a suitable position, then the limiting screw 611 is screwed into the limiting hole 601 again, then the hand wheel 65 is rotated to drive the screw rod 63 to drive the support disc 64 to move downwards along the rectangular rod 62 until contacting the ground, and the whole lifting platform is supported to enhance the stability of the support.

[0049] The working principle of the self-lifting and insulating telescopic platform is as follows:

[0050] When used, the lifting platform is arranged to the construction position by driving the trolley 2, the limiting of the limiting screw 611 is released, the rectangular rod 62 is pulled outwards to a suitable position, then the limiting screw 611 is screwed into the limiting hole 601 again, then the hand wheel 65 is rotated to drive the screw rod 63 to drive the support disc 64 to move downwards along the rectangular rod 62 until contacting the ground, and the whole lifting platform is supported to enhance the stability of the support.

[0051] Then the insulating ladder body 522 can slide and expand along the sliding groove 501 by using the slide rod 521, then the clamping groove 502 is clamped with the blocking rod 9 by rotating, so as to facilitate climbing to the insulating base 51 by using the insulating ladder body 522, and operation is carried out, the whole platform is made of insulating material, so as to facilitate live working, after climbing, the insulating ladder body 522 is inserted into the insulating base 51, after insertion, locking is carried out by using the locking bolt 511 arranged on the outer side of the insulating base 51, and the insulating ladder body 522 exposed outside can be used as an extension platform to expand the range of the platform after locking;

[0052] Finally, the remote controller 8 sends a lifting instruction to the controller 7, which controls the hydraulic cylinder 35 to drive the gantry 2 32 to move up and down along the gantry 1 31. When moving up and down, the steering wheel 1 361 is synchronously driven to move up and down, and then the gantry 3 33 is driven to move up and down along the gantry 2 32 through the chain 1 362. When moving up and down, the steering wheel 2 371 is driven to move up and down, and then the gantry 4 34 is driven to move up and down synchronously through the chain 2 372, thereby realizing the lifting of the entire lifting platform. After lifting, the hydraulic rod 3826 is controlled to extend. , the limit plate 3827 is blocked above the arc-shaped stopper 3825, limiting its upward rotation away from the ratchet groove, thereby achieving one-way locking of the ratchet 3824, thereby controlling the transmission shaft 3822 to stop rotation, and utilizing the transmission gear 3823 to engage with the rack plate 381 for self-locking. The one-way locking here is to limit its downward fall. When it is necessary to control the descent, the self-locking needs to be released. When it is necessary to rise, it can rise freely without releasing the self-locking. The entire lifting and climbing process is convenient, and it has lifting self-locking protection, and the lifting is very safe.

[0053] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.
