Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to an aerial work elevator. Background Art

[0002] Scissor lift is a widely used special equipment for aerial work. Its scissor mechanical structure makes the lifting platform have higher stability, a wide working platform and a higher load-bearing capacity, making the aerial work range larger and suitable for multiple people to work at the same time. It makes work more efficient and safer.

[0003] However, in actual use, when the area where the operation is required is close to the wall, the elevator cannot easily approach the wall. At the same time, some walls are usually provided with protruding tiles and other structures at the bottom, which further affects the proximity of the device to the wall. As a result, when the top platform is raised, it cannot be well close to the wall surface, which leads to inconvenience in operation. Moreover, when the operator leans out to operate, it is easy to encounter safety hazards. Therefore, a structure is needed that can facilitate personnel to approach when the elevator cannot approach. Utility Model Content

[0006] The extension plate used for adjustment is fixedly connected with sliding blocks on both sides of one end close to the inside of the lifting plate, and the inside of the lifting plate is rotatably connected with a screw rod, and the outer wall of the screw rod is rotatably connected with the sliding block;

[0007] The transmission assembly for transmission includes a driving motor and a pulley, one end of the screw rod passes through the interior of the lifting plate and is fixedly connected to the outer wall of the power output end of the driving motor with a pulley, and the multiple pulleys are connected through a transmission toothed belt;

[0008] The inner extended end of the electric push rod used for pushing is rotatably connected to the bottom of the extended plate, and the end of the outer wall of the electric push rod away from the extended plate is rotatably connected to a connecting block, and the electric push rod is rotatably connected to the bottom of the lifting plate through the connecting block.

[0009] Preferably, mounting plates are fixedly connected to the bottoms of both ends of the lifting plate. Scissor brace modules are staggeredly arranged at the bottom of the lifting plate, and a driving module is installed at the bottom of the scissor brace modules.

[0010] Preferably, the extending plate is slidably connected to the inside of the lifting plate. A groove corresponding to the extending plate is formed inside the lifting plate, and the outer wall of the lead screw rotates with the sliding block through a thread.

[0011] Preferably, a sliding frame is arranged at the top of one side of the extending plate away from the lifting plate. Both the blocking frame and the sliding frame are in a U shape, and both sides of the blocking frame are slidably connected to both sides of the sliding frame.

[0016] 2. When the extending plate moves, the sliding frame is driven to move through the fixing rod, so that the sliding frame and the blocking frame slide relative to each other to keep blocking the operator.

[0027] like Figure 1 , Figure 2As shown in the figure, mounting plates 101 are fixedly connected to the bottoms of both ends of the lifting plate 1. Scissor brace modules 102 are staggeredly arranged at the bottom of the lifting plate 1, and a drive module 103 is installed at the bottom of the scissor brace modules 102. The drive module 103 at the bottom drives the scissor brace modules 102 to rise, causing the lifting plate 1 to be driven, thus facilitating high-altitude operations.

[0028] As Figure 3 、 Figure 5 shown in the figure, the extension plate 2 is slidably connected to the inside of the lifting plate 1. A groove corresponding to the extension plate 2 is formed inside the lifting plate 1. The outer wall of the lead screw 201 rotates with the sliding block 202 through a thread. The drive motor 401 is fixedly connected to the center of the bottom of the lifting plate 1. The outer wall of the lead screw 201 is rotatably connected to the side wall of the lifting plate 1 through a bearing. By starting the transmission assembly 4, the drive motor 401 rotates to drive the pulley 402 to rotate, then the transmission belt 403 rotates to drive the pulley 402 at one end of the lead screw 201 to rotate, then the two lead screws 201 rotate accordingly, and then the movement of the sliding block 202 is driven, causing the extension plate 2 to be pushed out, enabling the extension plate 2 to approach the area where the operation is required.

[0029] As Figure 1 、 Figure 4 shown in the figure, a sliding frame 501 is provided at the top of the side of the extension plate 2 away from the lifting plate 1, and both the blocking frame 5 and the sliding frame 501 are in a U shape. The two sides of the blocking frame 5 are slidably connected to the two sides of the sliding frame 501. A plurality of fixing rods 502 are fixedly connected to the bottoms of both the blocking frame 5 and the sliding frame 501.

The bottom of the outer wall of the blocking frame 5 is fixedly connected to the top of the lifting plate 1 through the fixing rods 502. When the extension plate 2 moves, the sliding frame 501 is driven to move through the fixing rods 502, and then the sliding frame 501 and the blocking frame 5 slide relative to each other to keep blocking the operator.

[0030] Working principle: When in use, it can conveniently drive the scissor brace modules 102 to rise through the drive module 103 at the bottom. The scissor brace modules 102 drive the lifting plate 1 through the mounting plates 101, thus facilitating high-altitude operations. When the device cannot approach the position where the operation is required, the transmission assembly 4 can be conveniently started, then the drive motor 401 rotates to drive the pulley 402 to rotate, then the transmission belt 403 rotates to drive the pulley 402 at one end of the lead screw 201 to rotate, then the two lead screws 201 rotate accordingly, and then the movement of the sliding block 202 is driven, causing the extension plate 2 to be pushed out, enabling the extension plate 2 to approach the area where the operation is required, thus expanding the operation area of the operator and facilitating the operation.

[0031] When the extension plate 2 moves, the sliding frame 501 is driven to move by the fixed rod 502, so that the sliding frame 501 and the blocking frame 5 slide against each other to keep the operator blocked. At the same time, the electric push rod 3 can be started, so that the electric push rod 3 extends and moves with the extension plate 2. When the person moves to the top of the extension plate 2, the support of the bottom electric push rod 3 can effectively prevent the extension plate 2 from tilting to the bottom, thereby ensuring the safety of the operator.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
