Therefore, the maintenance space in front of the counterweight speed governor is relatively small, with the machine room floor space not exceeding 500×600mm. National regulations require that the machine room floor space must meet the 500×600mm requirement. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art. This utility model provides an elevator and its maintenance platform installation structure, which is simple in structure and can provide maintenance personnel with maintenance space that meets national requirements.

[0004] To address the aforementioned problems, this utility model proposes an elevator maintenance platform installation structure, characterized by comprising an elevator machine room, a main load-bearing beam, a secondary load-bearing beam, and a counterweight speed limiter.

[0005] The main load-bearing beam is fixed inside the elevator machine room. The angle between the main load-bearing beam and the front of the elevator machine room is 20-45°. The main load-bearing beam is equipped with a main frame and the counterweight speed limiter. The auxiliary load-bearing beam is fixed between the back of the elevator machine room and the main load-bearing beam.

[0006] A maintenance platform is installed between the main load-bearing beam and the front of the elevator machine room. The maintenance platform includes a first platform frame, a second platform frame, and a platform surface. The second platform frame is located at the end of the first platform frame facing the counterweight speed limiter. The platform surface is located on the top of the second platform frame and is situated above the main load-bearing beam.

[0007] As an improvement to the above technical solution, the height of the first platform frame is smaller than that of the second platform frame.

[0008] As an improvement to the above technical solution, the height of the first platform frame is 30-45% of the height of the second platform frame.

[0009] As an improvement to the above technical solution, the width of the platform surface is W, which is 500mm, and the length of the platform surface is L, which is 600mm.

[0010] As an improvement to the above technical solution, the platform surface includes a platform mounting frame and multiple support plates disposed on the platform mounting frame;

[0011] The platform mounting frame is a rectangular structure, and multiple support crossbars are provided inside the platform mounting frame. The support plate is laid on the support crossbars and is fixedly connected to the support crossbars.

[0012] As an improvement to the above technical solution, a gravity sensor switch is provided on the support crossbar, and the support plate is provided on the gravity sensor switch. The gravity sensor switch is electrically connected to the elevator's safety circuit and is used to disconnect the elevator circuit during maintenance.

[0013] As an improvement to the above technical solution, the gravity sensor switch is connected to a first indicator light, which is located on the second platform frame and is used to indicate that the gravity sensor switch is triggered; the safety circuit is connected to a second indicator light, which is located on the second platform frame and is used to indicate that the safety circuit is triggered.

[0015] The following are the beneficial effects of implementing this utility model:

[0016] Compared to existing technologies, this utility model provides a maintenance platform between the main load-bearing beam and the front of the elevator machine room. The maintenance platform includes a first platform frame, a second platform frame, and a platform surface. The second platform frame is located at the end of the first platform frame facing the counterweight speed limiter, and the platform surface is located on top of the second platform frame, situated above the main load-bearing beam. The platform surface avoids the space between the main load-bearing beam and the front of the elevator machine room, allowing for a platform surface area sufficient according to national standards. This utility model has a simple structure and provides sufficient maintenance platform space for main load-bearing beams installed at an angle in a small machine room, meeting national standards.
