Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. As long as the effect of the utility model can be exerted, various changes can be made to the implementation scheme.

[0039] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0040] Reference Figure 1-8 A working platform for an aerial work vehicle according to this implementation scheme is described.

[0041] The existing working platform comprises a base plate 1 and a left guardrail 2, a rear guardrail 3, a right guardrail 4 and a front guardrail 5 which are arranged around the top of the base plate 1.

[0042] The difference between this embodiment and the prior art is that:

[0043] A vertical railing 9 is fixed in the middle of the left guardrail 2, and the vertical railing 9 divides the left guardrail 2 into a fixed closed area and a movable opening and closing area; a guardrail net 8 is fixedly arranged in the fixed closed area. A movable door 10 and a movable guardrail net 13 are arranged on the left guardrail 2, and the movable door 10 and the movable guardrail net 13 are arranged in the movable opening and closing area. The movable door 10 and the movable guardrail net 13 are adjustable in the movable opening and closing area, and a space for human body to pass through is formed after the movable door 10 and the movable guardrail net 13 are opened.

[0044] The movable door 10 includes a sleeve 100, an opening slot 101 and a crossbeam 103. There are two sleeves 100, which are respectively sleeved on the vertical railing 9 and the left guardrail 2. The opening slot 101 is opened on the opposite side of the two sleeves 100. End rods 104 are provided at both ends of the crossbeam 103, and the two end rods 104 are respectively inserted into the opening slots 101 of the two sleeves 100, and the end rods 104 at both ends of the crossbeam 103 can slide up and down in the opening slot 101. The top of the sleeve 100 is close to the top position of the left guardrail 2, and the length of the opening slot 101 is the formation space of the crossbeam 103. When the crossbeam 103 moves from the bottom to the top position in the opening slot 101, the crossbeam 103 moves from the middle of the left guardrail 2 to the top.

[0045] Furthermore, one side inner wall of the opening slot 101 is a plane, and the other side inner wall is provided with a plurality of positioning holes 102, and the end rods 104 can be engaged in the positioning holes 102. When the crossbeam 103 moves, the end rods 104 are close to the inner wall of the plane, and when it needs to be fixed, the end rods 104 are engaged in the positioning holes 102, so that the crossbeam 103 can be fixed at any position in the opening slot 101.

[0046] A movable guardrail net 13 is also provided in the movable opening and closing area, and the movable guardrail net 13 is provided below the movable door 10; the bottom of the movable guardrail net 13 is rotatably connected to the left guardrail 2, and a lock 14 is provided between one side of the movable guardrail net 13 and the left guardrail 2. After the lock 14 is opened, the movable guardrail net 13 rotates with the bottom as the axis. At this time, the crossbeam 103 moves to the top position, and the movable guardrail net 13 flips outward, so that the movable opening and closing area is completely exposed for the staff to enter and exit. On the contrary, after the crossbeam 103 moves to the bottom position and the movable guardrail net 13 is fixed to the left guardrail 2 by the lock 14, the crossbeam 103 and the movable guardrail net 13 form a barrier for the movable opening and closing area, thereby improving the safety of the movable opening and closing area.

[0047] The rear guardrail 3 is provided with a safety assembly 11 for fixing a safety rope; the safety assembly 11 comprises a back plate 118, a light rod 110, a C-shaped gusset plate 113, a sliding member 111, a stop plate 116 and a positioning ring 114. The back plate 118 is fixed to the rear guardrail 3; the light rod 110 is provided at the front side of the back plate 118, and an intermediate body 117 is connected between the light rod 110 and the back plate 118; the length of the light rod 110 is the stroke length of the C-shaped gusset plate 11.

[0048] An opening 112 is formed at the front side of the C-shaped buckle plate 113 . The C-shaped buckle plate 113 is buckled onto the polished rod 110 . The opening width of the opening 112 is greater than the width of the intermediate body 117 .

[0049] The sliding member 111 is fixed to the inner side of the C-shaped buckle plate 113, so that the C-shaped buckle plate 113 can slide on the light rod 110 through the sliding member 111; in one embodiment, the sliding member 111 is a C-shaped steel with a U-shaped groove formed therein, and a ball or roller is arranged in the U-shaped groove.

[0050] There are two limit plates 116 fixed on the polished rod 110, and the two limit plates 116 are used to limit the sliding distance of the C-shaped buckle plate 113 on the polished rod 110. The positioning ring 114 is fixed on the outer wall of the C-shaped buckle plate 113, and the inner side of the positioning ring 114 has a cavity 115 for inserting a safety rope.

[0051] When in use, the safety rope is passed through the cavity 115 and fixed on the positioning ring 114. The safety rope is fixed on the worker, and a drag force is generated when the worker moves. The safety rope pulls the C-shaped buckle plate 113 when dragging, and the C-shaped buckle plate 113 slides horizontally on the light rod 110 through the sliding member 111. When sliding, the two ends of the opening 112 of the C-shaped buckle plate 113 will be engaged with the two sides of the intermediate body 117, so that it is fixed on the light rod 110 during the sliding process, so that the safety rope can follow the movement at any time when the worker moves on the work platform, thereby improving safety.

[0052] The front guardrail 5 and the front side surface of the bottom plate 1 form a curved surface structure. The curved surface structure enables the working platform to fit on the building surface with a curved surface. At the same time, the curved surface structure on both sides of the front guardrail 5 and the front side surface of the bottom plate 1 is a flat structure, and the flat structure enables the working platform to fit on the flat building surface. When the curved surface of the building surface is larger than the curved surface structure of the working platform, the curved surface structure on both sides is a flat structure that fits on the building surface and performs normal operations. When the curved surface of the building surface is smaller than the curved surface structure of the working platform, the curved surface structure can fit on the building surface as much as possible to facilitate work.

[0053] Specifically, the front guardrail 5 includes a curved guardrail 52 and a planar end guardrail 51 arranged on both sides of the curved guardrail 52; the front side surface of the base plate 1 forms a curved surface 6, and both sides of the curved surface 6 are planes; wherein, the curved surface 6 overlaps with the curved guardrail 52 under the top view projection; the curved guardrail 52 and the curved surface 6 constitute a curved surface structure.

[0054] The front side of the base plate 1 is provided with anti-collision components 7 , and there are three anti-collision components 7 , two of which are arranged at both ends of the base plate 1 , specifically on the planes on both sides of the arc surface 6 , and one is arranged in the middle of the arc surface 6 .

[0055] The anti-collision component 7 includes a base plate 70 fixed on the bottom plate 1, a connecting beam 71 is fixed on the base plate 70, a sleeve 72 is fixed on the connecting beam 71, a spring 75 is fixed in the sleeve 72, the spring 75 extends out of the sleeve 72, and a disc 76 is fixed to one end of the spring 75 extending out of the sleeve 72.

[0056] The anti-collision component 7 also includes an inner center rod 73, which is fixed in the sleeve 72 and penetrates the inner side of the spring 75. A contact sensor 74 is fixed to the end of the inner center rod 73. When the spring 75 is compressed by collision, the disc 76 contacts the contact sensor 74.

[0057] When in use, when the working platform touches the building surface, it will first touch the anti-collision component 7. There are two situations when the collision occurs. First, when the working platform is close to the flat building surface, the two anti-collision components 7 on the plane will touch the building surface; second, when the working platform is close to the curved building surface, the anti-collision component 7 on the curved surface 6 will touch the building surface. When in contact, the building surface first touches the disc 76. When the working platform continues to advance, it will compress the spring 75, causing the spring 75 to retract. During the retraction process, the disc 76 touches the contact sensor 74, and the contact sensor 74 transmits an electrical signal to the aerial work vehicle, and the aerial work vehicle stops the work platform from continuing to advance.

[0058] A tool plate 12 is provided on the right guardrail 4 , and a plurality of hooks are provided on the tool plate 12 , on which tools can be hooked.

[0059] Working principle: When in use, the staff opens the lock 14, the movable guardrail net 13 is turned outward, and the crossbeam 103 is moved to the top position, so that the movable opening and closing area is fully exposed, and the staff enters the working platform. The movable guardrail net 13 is turned back and fixed by the lock 14, and the crossbeam 103 is moved to the bottom position. The safety rope on the staff's body is passed through and fixed in the cavity 115 in the positioning ring 114.

[0060] When the working platform moves, when it touches a flat or curved building surface, it will touch the anti-collision component 7; when touching, the building surface first touches the disc 76, and when the working platform continues to advance, it will compress the spring 75, causing the spring 75 to retract. During the retraction process, the disc 76 touches the contact sensor 74, and the contact sensor 74 transmits an electrical signal to the aerial work vehicle, and the aerial work vehicle stops the continued advancement of the working platform.

[0061] When the workers are working on the work platform, the workers move to generate a drag force, and the safety rope pulls the C-shaped buckle plate 113 when dragging. The C-shaped buckle plate 113 slides horizontally on the light rod 110 through the sliding member 111, so that the safety rope can follow the workers when they move on the work platform, thereby improving safety.

[0062] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
