[0023] Please see Figure 1-3A working platform for assembling elevator cars includes a base 1, a support device 2 on the upper surface of the base 1, a lifting device 3 on the upper surface of the base 1 for adjusting the height during operation, a connecting device 4 on the movable end of the lifting device 3, a limiting device 5 inside the support device 2 for stabilizing and maintaining the horizontal position of the movable end of the lifting device 3 during lifting, and a buffer device 6 on the upper surface of the base 1 for cushioning the movable end of the lifting device 3 during descent.

[0024] Specifically, the process is as follows: First, the base 1 is fixed to the working position inside the elevator shaft. Then, the supporting device 2, the movable end of the lifting device 3, the connecting device 4, and the limiting device 5 are placed on the upper surface of the base 1 through multiple hoisting operations. Next, the supporting device 2 is fixedly installed on the upper surface of the base 1. Then, the limiting device 5 is installed inside the supporting device 2 and cooperates with the movable end of the lifting device 3 for installation. This avoids the high-risk problem of traditional ground assembly followed by overall hoisting. During use, the lifting device 3 drives its movable end to rise and fall. The connecting device 4 limits and fixes the movable end and transmission end of the lifting device 3, and the limiting device 5 limits the movable end of the lifting device 3, thereby improving the stability of the lifting device 3 during use and thus improving the safety of elevator operation.

[0025] The support device 2 includes a channel steel 201 and a fixing plate 202. The channel steel 201 is fixedly installed on the upper end face of the base 1, and the fixing plate 202 is fixedly installed on the upper end face of the channel steel 201.

[0026] Specifically, the channel steel 201 and the fixing plate 202 provide stable support, thereby improving the safety of workers during operation.

[0027] The lifting device 3 includes a motor 301, a sliding groove 302, a double-threaded rod 303, a stop block 304, a sliding seat 305, a lifting rod 306, and a lifting plate 307.

The sliding seat 305 is slidably installed in the sliding groove 302 and is threadedly connected to the double-threaded rod 303. The lifting rod 306 is rotatably installed on the outer surface of the sliding seat 305, and the lifting plate 307 is fixedly installed on the upper end face of the lifting rod 306.

[0028] Specifically, the threads at both ends of the double-threaded rod 303 are arranged in opposite directions. The double-threaded rod 303 is driven to rotate by the motor 301, which in turn drives the sliding seat 305 to rotate within the sliding groove 302. The movement of the sliding seat 305 is limited by the stop block 304, thereby enabling the sliding seat 305 to drive the lifting rod 306 to move up and down, which in turn drives the lifting plate 307 to move up and down, thus allowing the working height to be adjusted during operation.

[0029] The connecting device 4 includes a connecting plate 401 and a connecting seat 402. The connecting plate 401 is fixedly installed on the left and right side walls of the lifting rod 306, and the connecting seat 402 is fixedly installed on the upper end face of the lifting plate 307. The connecting plate 401 and the connecting seat 402 are fixedly connected.

[0030] Specifically, the stability of the connection between the lifting plate 307 and the lifting rod 306 is improved by connecting plate 401 and connecting seat 402, thereby improving the stability of the lifting plate 307 during use.

[0031] The limiting device 5 includes a fixed base 501, a fixed rod 502, a limiting rod 503, and a limiting seat 504.

The limiting seat 504 is fixedly installed on the front and rear side walls and the left and right side walls of the lifting plate 307, and the limiting seat 504 is slidably connected to the limiting rod 503.

[0032] Specifically, the sliding connection between the limiting rod 503 and the limiting seat 504 limits the up and down movement of the lifting plate 307, thereby improving the stability of the lifting plate 307 during movement.

[0033] The buffer device 6 includes a buffer seat 601 and a buffer pad 602. The buffer seat 601 is fixedly installed on the upper end face of the base 1, and the buffer pad 602 is fixedly installed on the upper end face of the buffer seat 601.

[0034] Specifically, the buffer pad 602 provides buffer protection for the lifting plate 307 during descent.

[0035] In summary:

[0036] First, the base 1 is fixed to the working position inside the elevator shaft. Then, the supporting device 2, the movable end of the lifting device 3, the connecting device 4, and the limiting device 5 are placed on the upper surface of the base 1 through multiple hoisting operations. Next, the supporting device 2 is fixedly installed on the upper surface of the base 1, and the limiting device 5 is installed inside the supporting device 2, cooperating with the movable end of the lifting device 3. This avoids the high-risk problem of traditional ground assembly followed by overall hoisting. During use, the lifting device 3 drives its movable end to rise and fall. The connecting device 4 limits and fixes the movable end and transmission end of the lifting device 3, and the limiting device 5 limits the movable end of the lifting device 3, thereby improving the stability of the lifting device 3 during use and thus enhancing the safety of elevator operation. The channel steel 201 and the fixing plate 202 provide stable support, thereby improving the safety of operators during operation. (Double-ended thread) The two ends of the rod 303 have opposite threads. The motor 301 drives the double-threaded rod 303 to rotate, which in turn drives the sliding seat 305 to rotate within the sliding groove 302. The stop block 304 limits the movement of the sliding seat 305, allowing the sliding seat 305 to drive the lifting rod 306 to move up and down, thereby driving the lifting plate 307 to move up and down. This allows for adjustment of the working height during operation. The connecting plate 401 and the connecting seat 402 enhance the stability of the connection between the lifting plate 307 and the lifting rod 306, thus improving the stability of the lifting plate 307 during use. The sliding connection between the limiting rod 503 and the limiting seat 504 limits the up and down movement of the lifting plate 307, thus improving the stability of the lifting plate 307 during movement. The buffer pad 602 provides cushioning protection for the lifting plate 307 during descent.
