[0003] The purpose of this utility model is to provide a maintenance platform for platform ladders, which aims to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: The platform elevator maintenance platform includes support components installed on both sides of the inner wall of the elevator shaft. The support components include a fixing plate, which is bolted to the inner wall of the elevator shaft. One end of the fixing plate is rotatably connected to a pressure plate. Both the fixing plate and the pressure plate have through grooves, and each through groove has a limiting groove. One end of the pressure plate is rotatably connected to a support plate. Two flexible clamping plates are provided on the inner wall of the elevator shaft. The support plate can be restricted to the inner wall of the elevator shaft by the two clamping plates. A protrusion is provided at the end of the support plate away from the pressure plate. The protrusion can be placed in the limiting groove. The platform also includes a support part placed on the two sets of support components. The support part includes a horizontal plate. Hanging plates are provided at both ends of the horizontal plate. One end of the hanging plate has a hook groove that cooperates with the limiting groove. The other end of the hanging plate has several round rods. Through holes for accommodating the round rods are provided on the horizontal plate. The hanging plate and the horizontal plate are connected by an elastic element.
[0005] Preferably, when the protruding end of the support plate enters the limiting groove on the fixing plate, the upper surface of the pressure plate is in a horizontal state.
[0006] Preferably, baffles are provided at both ends of the horizontal plate.
[0007] Preferably, reinforcing plates are provided on both sides of the horizontal plate.
[0008] Preferably, the horizontal plate, hanging plate, and round rod are all made of aluminum alloy.
[0009] The beneficial effects of this utility model are:

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0018] like Figure 1-5As shown, a maintenance platform for a platform elevator includes support components installed on both sides of the inner wall of an elevator shaft 1. The support components include a fixing plate 2, which is bolted to the inner wall of the elevator shaft 1. A pressure plate 3 is rotatably connected to one end of the fixing plate 2. Both the fixing plate 2 and the pressure plate 3 have through grooves, and each through groove has a limit groove 4 inside. A support plate 5 is rotatably connected to one end of the pressure plate 3. Two flexible clamping plates 6 are provided on the inner wall of the elevator shaft 1, and the support plate 5 can be restricted by the two clamping plates 6. On the inner wall of the elevator shaft 1, a protrusion 7 is provided at the end of the support plate 5 away from the pressure plate 3. The protrusion 7 can be placed in the limiting groove 4. It also includes a support part placed on two sets of support components. The support part includes a horizontal plate 8. Hanging plates 9 are provided at both ends of the horizontal plate 8. One end of the hanging plate 9 is provided with a hook groove 10 that cooperates with the limiting groove 4. The other end of the hanging plate 9 is provided with several round rods 11. The horizontal plate 8 is provided with through holes for accommodating the round rods 11. The hanging plate 9 and the horizontal plate 8 are connected by an elastic member 12.
[0019] When the support assembly is not in use, the fixing plate 2, the pressure plate 3 and the support plate 5 are attached to the inner wall of the elevator shaft 1 by two clamping plates 6. At this time, the thickness of the part of the support assembly protruding from the inner wall of the elevator shaft 1 is low, and no component of the elevator system will directly contact the support assembly.
[0020] Furthermore, when the support components are not in use, the support needs to be hung in one of the support components. Specifically, by placing the hook groove 10 on one of the hanging plates 9 into the limiting groove 4 on the fixed plate 2, the connection stability between the hanging plate 9 and the fixed plate 2 can be improved through the cooperation of the hook groove 10 and the limiting groove 4. After the hanging plate 9 and the fixed plate 2 are connected, the horizontal plate 8 can maintain a vertical posture, thereby keeping the horizontal plate 8 and the inner wall of the elevator shaft 1 at a relatively close distance. At the same time, no component in the elevator system will directly contact the components in the support.
[0021] When it is necessary to repair the host at a higher position, a repair platform needs to be set up. Specifically, firstly, the horizontal plate 8 is moved upward to separate the hook groove 10 from the limiting groove 4 on the fixed plate 2. The support part is then removed from the support assembly. Then, the support plate 5 is moved out between the two clamping plates 6 through the protrusion 7 on the support plate 5. Then, by rotating the support plate 5 and the pressure plate 3, the protrusion 7 on the support plate 5 enters into the limiting groove 4 on the fixed plate 2. At this time, the support plate 5 can support the pressure plate 3. Then, the hanging plates 9 at both ends of the horizontal plate 8 are pulled out so that the hook groove 10 on both hanging plates 9 can enter into the limiting groove 4 on the pressure plate 3. Through the elastic element 12, the hanging plates 9 can maintain a tight connection with the pressure plate 3, thereby improving the stability of the horizontal plate 8 after placement and making it convenient for staff to stand on the horizontal plate 8 to repair the host.
[0022] Furthermore, when the end of the support plate 5 with the protrusion 7 enters the limiting groove 4 on the fixed plate 2, the upper surface of the pressure plate 3 is in a horizontal state, increasing the contact area between the hanging plate 9 and the pressure plate 3 and improving the stability of the horizontal plate 8.
[0023] Furthermore, baffles 13 are provided at both ends of the horizontal plate 8. When the lower end of the through groove on the fixed plate 2 is clamped by the baffles 13 and the hanging plate 9, the elastic element 12 is in a stretched state, so the support part can be hung on the fixed plate 2 more stably.
[0024] Furthermore, reinforcing plates 14 are provided on both sides of the horizontal plate 8, which can improve the bending resistance of the horizontal plate 8.
[0025] The width of the horizontal plate 8 shall not be less than 35cm to facilitate use by maintenance personnel.
[0026] Furthermore, the horizontal plate 8, hanging plate 9, and round rod 11 are all made of aluminum alloy, which makes them lightweight and facilitates the disassembly and installation of the horizontal plate 8. Meanwhile, the fixing plate 2, pressure plate 3, and support plate 5 can be made of stainless steel, iron, or aluminum alloy.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
