[0036] There are two groups of auxiliary support components 6 , and the two groups of auxiliary support components 6 are symmetrically installed at the two ends of the bottom of the base plate 1 .

[0037] A controller 7 is embedded on the base plate 1. The controller 7 is electrically connected to the hydraulic cylinder 35 and the hydraulic rod 3826. The controller 7 is also connected to a remote controller 8 via wireless communication.

[0038] Among them, there are four first transmission chains 36, and the four first transmission chains 36 are symmetrically installed on the gantry 2 32 and the gantry 3 33 in a group of two.

[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, and then the lifting command is transmitted to the controller 7 through the remote control 8 to control the hydraulic cylinder 35 to drive the gantry frame 2 32 to be lifted and lowered along the gantry frame 1 31. During lifting, the steering wheel 1 361 is synchronously driven to be lifted and lowered, and then the gantry frame 33 is driven to be lifted and lowered along the gantry frame 2 32 through the chain 1 362. During lifting, the steering wheel 2 371 is driven to be lifted and lowered, and then the gantry frame 4 34 is driven to be lifted and lowered synchronously through the chain 2 372, so as to realize the lifting and lowering 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 and lowering self-locking protection, and the lifting and lowering 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 installed at the four inner corners of the gantry 1 31, the gantry 2 32 and the gantry 3 33 in sequence, and a locking member 382 installed at the four inner corners of the gantry 2 32, the gantry 3 33 and the gantry 4 34 in sequence;

[0042] The locking member 382 includes a vertical plate 3821 which is sequentially installed at the bottom ends of the four inner corners of the gantry frame 2 32, the gantry frame 33 and the 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 meshed with the rack plate 381 on the same side, and a ratchet 3824 is fixedly sleeved on the other end of the transmission shaft 3822, an arc-shaped stopper 3825 which is limited by the ratchet 3824 is rotatably installed on the vertical plate 3821, a hydraulic rod 3826 is fixedly installed on the top end of the vertical plate 3821, and 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 in use, 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 during 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 Without restricting the ratchet 3824, when 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 and the rack plate 381 to engage 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 is slidably matched with a slide groove 501 provided on the insulating base 51, and an insulating ladder body 522 is fixedly installed on the slide bar 521. A handrail 523 is installed on the upper surface of the end of the insulating ladder body 522 that is away from the slide bar 521, and a card 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 card slot 502 are installed at both ends of the base plate 1 through brackets;

[0045] The length of the handrail 523 is half of 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 make the slot 502 engage with the blocking rod 9, so as to facilitate the use of the insulating ladder main body 522 to climb onto the insulating base 51 for operation. The entire platform is made of insulating material, which is convenient for live work. After climbing, the insulating ladder main body 522 is inserted into the insulating base 51. After insertion, it can be locked using the locking bolts 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 includes a rectangular tube 61, which is fixedly mounted on the bottom of the base plate 1, and a rectangular rod 62 is symmetrically inserted in the rectangular tube 61, and a screw 63 is threadedly mounted on one end of the rectangular rod 62 away from the rectangular tube 61, a support plate 64 is fixedly mounted on the bottom end of the screw 63, and a hand wheel 65 is fixedly mounted on the top end of the screw 63. A plurality of limiting holes 601 are evenly opened on the rectangular rod 62, and limiting screws 611 cooperating with the pins of the limiting holes 601 are threadedly mounted on the outer sides of both ends of the rectangular tube 61;

[0048] It should be noted that when the auxiliary support assembly 6 is in use, when the lifting platform is dragged to the construction position, the restriction of the limit screw 611 is released, the rectangular rod 62 is pulled outward to a suitable position, and then the limit screw 611 is re-screwed into the limit hole 601, and then the handwheel 65 is turned to drive the screw 63 to drive the support plate 64 to move downward along the rectangular rod 62 until it touches the ground, thereby propping up the entire lifting platform and enhancing the stability of the support.

[0049] The working principle of the self-lifting insulating telescopic platform provided by the present invention is as follows:

[0050] When in use, the lifting platform is arranged to the construction site by driving the trolley 2, the restriction of the limit screw 611 is released, the rectangular rod 62 is pulled outward to a suitable position, and then the limit screw 611 is screwed back into the limit hole 601, and then the hand wheel 65 is turned to drive the screw rod 63 to drive the support plate 64 to move downward along the rectangular rod 62 until it touches the ground, so as to prop up the entire lifting platform and enhance the stability of the support;

[0051] Then, the insulating ladder body 522 can slide and unfold along the slide groove 501 by using the slide rod 521, and then rotate to make the slot 502 engage with the blocking rod 9, so that the insulating ladder body 522 can be used to climb onto the insulating base 51 for operation. The entire platform is made of insulating material, which is convenient for live work. After climbing, the insulating ladder body 522 is inserted into the insulating base 51. After insertion, it can be locked by using the locking bolts 511 provided on the outer side of the insulating base 51. After locking, the insulating ladder body 522 exposed outside can be used as an extension platform to expand the range of the platform;

[0052] Finally, the remote controller 8 transmits the lifting command to the controller 7, controls the hydraulic cylinder 35 to drive the gantry frame 2 32 to lift along the gantry frame 1 31, and drives the steering wheel 1 361 to lift synchronously during the lifting, and then drives the gantry frame 3 33 to lift along the gantry frame 2 32 through the chain 1 362, and drives the steering wheel 2 371 to lift during the lifting, and then drives the gantry frame 4 34 to lift synchronously through the chain 2 372, so as to realize 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 rotating, 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 does not need to release the self-locking and can rise freely. The entire lifting and climbing process is convenient, and it has lifting and climbing self-locking protection, and the lifting and climbing is very safe.
