[0035] The lifting assembly 3 includes multiple groups of upper brackets 311 and lower brackets 312. The upper brackets 311 are all rotatably connected to the lifting connection shafts 305, and the axis center is close to the second end of the upper bracket 311. The first end of the upper bracket 311 is movably connected to the first end of the lower bracket 312, and the first end of the lower bracket 312 is fixedly connected to the base plate 503. The lower bracket 312 is also rotatably connected to the lifting connection shafts 305, and the axis center of the lifting connection shafts 305 is close to the first end of the lower bracket 312; the lifting connection shafts 305 on the upper bracket 311 close to the base plate 503 are fixedly connected to the first lifting gear 306, and the lifting connection shafts 305 on the lower bracket 312 close to the platform plate 502 are fixedly connected to the second lifting gear 307.

[0037] The adjustment assembly 1 also includes a handle 101, which is rotatably connected to the adjustment bracket 102. The first end of the sliding rod 109 is fixedly connected to the adjustment bracket 102, and the second end of the sliding rod 109 is slidably connected to the adjustment support block 110. The handle 101 is also fixedly connected to the bevel gear 103, and the adjustment bracket 102 is also rotatably connected to the upper gear 104. The threaded rod 106 is also fixedly connected to the lower gear 105, the lower gear 105 is meshed with the upper gear 104, and the upper gear 104 is also meshed with the bevel gear 103. The threaded rod 106 is frictionally connected with a chain 107, and the threaded rods 106 on both sides are connected by the chain 107 to transmit power and jointly control the movement of the adjustment support blocks 110 on both sides.

[0038] like Figure 4 and Figure 7 As shown, when in use, the handle 101 is manually rotated to drive the bevel gear 103 to rotate, the bevel gear 103 drives the upper gear 104, the upper gear 104 drives the lower gear 105 to rotate, and then drives the threaded rod 106 to rotate. There is no thread on the threaded rod 106 where it contacts the adjustment bracket 102. The threaded rod 106 controls the adjustment support blocks 110 on both sides to move toward the adjustment bracket 102 through the thread. At the same time, the sliding rod 109 fixes the position of the adjustment bracket 102 to prevent the adjustment bracket 102 from rotating.

[0039] The second end of the first upper push rod 304 is fixedly connected to the lifting connecting shaft 305 on another upper bracket 311, the first end of the first upper push rod 304 is rotatably connected to the first end of the second lower push rod 313, the second end of the second lower push rod 313 is fixedly connected to the lifting connecting shaft 305 on another lower bracket 312, the first end of the second lower push rod 313 is also rotatably connected to the first end of the first short link 303, the second end of the first short link 303 is slidably connected to the first end of the lifting push rod 302, the first end of the lifting push rod 302 is fixedly connected to the output rod of the lifting motor 301, and the lifting motor 301 is also fixedly connected to the base plate 503.

[0040] like Figure 11 and Figure 12As shown, two lower brackets 312 and two upper brackets 311 are provided on each side, and are rotatably connected to the lifting connecting shaft 305, and the lifting connecting shafts 305 on the middle upper bracket 311 and the lower bracket 312 are fixedly connected to the first lifting gear 306 and the second lifting gear 307 respectively. The axis center position of the lifting connecting shaft 305 on the upper bracket 311 is biased upward, and the axis center position of the lifting connecting shaft 305 on the lower bracket 312 is biased downward. A sliding groove is provided at the first end of the lifting push rod 302. Its purpose is to ensure that after the platform is lowered, each connecting rod can fall completely, and there will be no supporting force due to the obstruction of the lifting push rod 302, or the lifting push rod 302 moves too much to the right and falls too much, exceeding the limit of each connecting rod and damaging parts. That is, the axis of the second end of the first short connecting rod 303 is in the sliding groove of the first end of the lifting push rod 302, and does not contact the two ends of the sliding groove. At this time, each connecting rod is only subjected to gravity and the pressure of the upper parts, and can be stacked freely without external pulling or pushing.

[0041] When in use, start the lifting motor 301, the output rod pulls the second end of the lifting push rod 302, and the first end of the lifting push rod 302 pushes the shaft on the first lower push rod 308, driving the second end of the first lower push rod 308 to rotate counterclockwise around the first end of the first lower push rod 308, and also drives the second end of the first short link 303 to move upward, and the first end of the first short link 303 pulls the first end of the second lower push rod 313 to rotate around the second end of the second lower push rod 313, thereby driving the two upper brackets 311 close to the bottom plate 503 to move upward through the first upper push rod 304 and the second upper push rod 310, and at the same time driving the lifting connecting shaft 305 and the first lifting gear 306 on the two upper brackets 311 to rotate, and through gear meshing, drive the second lower push rod 313 and the first lower push rod 308 and other parts close to the side of the platform plate 502, thereby pushing the platform plate 502 to move upward.

[0042] The support assembly 2 includes a support motor 201, which is fixedly connected to the base plate 503. The first end of the support connecting rod 202 is rotatably connected to the output rod of the support motor 201, and the second end of the support connecting rod 202 is rotatably connected to the support upper connecting plate 203. The support upper connecting plate 203 is rotatably connected to multiple moving wheels 204, and each moving wheel 204 is provided with a support spring 205. The first end of the support spring 205 is fixedly connected to the support upper connecting plate 203, and the second end of the support spring 205 is fixedly connected to the base plate 503.

[0043] like Figure 6As shown, when in use, the support motor 201 is started, the output rod pushes the support connecting rod 202 to move, and the support connecting rod 202 pushes the support upper connecting plate 203 to move upward, thereby causing the wheels of the moving wheel 204 to move toward the platform plate 502, so that the support block on the platform plate 502 contacts the ground, fixing the position of the lifting platform and increasing the stability of the platform.

[0044] The protection component 4 includes a control rod 401, and multiple groups of protection blocks 402 are fixedly connected to the control rod 401. The first end of the protection block 402 is provided with an inclined surface, and the second end of the protection block 402 is fixedly connected to the first end of the protection spring 403, and the second end of the protection spring 403 is fixedly connected to the protrusion on the platform plate 502.

[0045] The protective assembly 4 also includes an upper connecting plate 406, to which the first ends of multiple groups of protective connecting shafts 404 are fixedly connected, and the second ends of the protective connecting shafts 404 are fixedly connected to another upper connecting plate 406. The protective connecting shafts 404 are provided with inclined grooves that match the inclined surfaces on the protective block 402. The upper connecting plate 406 is also slidably connected to a side plate 405.

[0046] like Figure 8 、 Figure 9 and Figure 10 As shown, before using, the protective connecting shaft 404 is manually lifted, and the inclined groove on the protective connecting shaft 404 cooperates with the inclined surface of the platform plate 502, so that when the protective connecting shaft 404 moves upward, it pushes the protective stopper 402 to move to the right, squeezing the protective spring 403. When the protective connecting shaft 404 stops moving, the protective connecting shaft 404 falls naturally until the nearest slide groove contacts the protective stopper 402, and the protective stopper 402 clamps the protective connecting shaft 404, thereby fixing the position of the protective connecting shaft 404, completing the lifting of the platform guardrail, and manually pushing the two side panels 405 toward each other to complete the movement of the side guardrail. During work, if the guardrail on the side close to the wall affects work, the guardrail on one side can be controlled to fall, and the control lever 401 is manually pulled on the platform, and the control lever 401 is pushed outside the platform to drive the protective stopper 402 to squeeze the protective spring 403, and the protective connecting shaft 404 is no longer supported by the protective stopper 402 and falls freely.

[0047] The platform assembly 5 further includes a sliding plate 501 , which is slidably connected to a platform plate 502 , to which a first end of a cross-connecting frame 108 is fixedly connected, and a second end of the cross-connecting frame 108 is slidably connected to another platform plate 502 .

[0048] The platform assembly 5 also includes a connecting cross plate 504, which is fixedly connected to the two upper brackets 311 close to the base plate 503. The first end of the cross connecting frame 108 is also fixedly connected to the connecting cross plate 504, and the second end of the cross connecting frame 108 is slidably connected to another connecting cross plate 504.

[0049] When adjusting the width of the platform, the sliding plate 501 on the platform can be manually controlled to slide on the platform plate 502, and when adjusted to a suitable position, it is fixed by a clamping block.

[0050] like Figure 7 As shown, there are multiple groups of cross-connecting frames 108, which are used to ensure the stability of the left and right sides after the platform is raised.
