Description

A speed limiter bracket for machine-room-less elevators Technical Field

[0001] This utility model belongs to the field of elevator accessories technology, and relates to a speed limiter bracket for machine room-less elevators. Background Technology

[0002] The elevator speed governor is one of the safety control components in the elevator safety protection system. When the elevator car overspeeds or even falls due to any reason during operation, and all other safety protection devices fail, the speed governor and safety brakes will activate in conjunction, stopping the elevator car. In machine-room-less elevators, the speed governor needs to be fixed to the top of the shaft using a mounting bracket.

[0003] Because the governor's wire rope forms a closed loop around the governor's pulley and the tension pulley in the pit, with its head secured to the elevator car and connected to the safety gear via a mechanical linkage, it forms a safety protection system. The governor's wire rope moves up and down with the elevator car within the shaft, one end connected to the elevator car and moving in the same direction, while the other end moves in the opposite direction. Currently, in commercially available designs, both ends of the governor's wire rope are parallel and close to the elevator car. During elevator operation, considering the factor of wire rope swaying, there is a risk of interference between the reverse-moving end of the governor's wire rope and elevator car components, potentially causing the governor to malfunction and resulting in safety issues.

[0004] To address this issue, a speed governor bracket for machine-room-less elevators was designed to overcome the aforementioned problems. Summary of the Invention

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a speed limiter bracket for machine room-less elevators that is simple and reasonable in structure, practical and convenient, safe, efficient and stable.

[0006] This utility model is achieved through the following technical solution: a speed governor bracket for a machine room-less elevator, comprising a speed governor bracket body. One end of the speed governor bracket body is fixed to a vertically arranged shaft guide rail by a pressure guide plate and bolts. A speed governor is fixedly installed at the upper end of the speed governor bracket body by bolts. One end of the steel wire rope in the speed governor runs in the same direction as the elevator car, while the other end of the steel wire rope runs in the opposite direction to the elevator car, with a gap between them. This is to prevent the reverse-running end of the speed governor steel wire rope from interfering with the elevator car components during elevator operation, thus preventing the speed governor from malfunctioning.

[0007] Preferably, the speed limiter bracket body consists of a first bent plate, a second bent plate, and two reinforcing ribs. Each of the first and second bent plates has a corresponding mounting through hole. Bolts are used to sequentially pass through the mounting through holes of the first and second bent plates to connect and fix the first and second bent plates. Two reinforcing ribs with the same cross-section as the second bent plate are welded to the opposite sides of the second bent plate.

[0008] Preferably, the first bending plate has its upper and lower ends bent outward at 90 degrees, forming a straight section in the middle and bent sections on both sides, with the bent sections on both sides having the same shape, making the first bending plate have an overall C-shaped structure. The second bending plate has its upper and lower ends bent outward at 90 degrees, forming a straight section in the middle and bent sections on both sides, with the upper bent section being longer than the lower bent section, making the first bending plate have an overall inverted L-shaped structure. One corresponding mounting through hole is provided on the straight section of the first and second bending plates. After the straight sections of the first and second bending plates are tightly attached to each other, bolts are sequentially passed through the mounting through holes of the first and second bending plates to achieve the connection and fixation between the first and second bending plates. Multiple threaded through holes are provided on the upper bent section of the first bending plate, and bolts are inserted into the threaded through holes to achieve the connection and fixation between the speed limiter bracket body and the speed limiter.

[0009] Preferably, one end of the wire rope in the speed limiter is located on the outer side of the first bending plate, near the shaft guide rail, and is fixed to the elevator car to run in the same direction. The other end of the wire rope is located on the outer side of the second bending plate, away from the shaft guide rail, and runs in the opposite direction to the elevator car. This is to ensure that the speed limiter wire rope at the reverse running end does not interfere with the elevator car components.

[0010] Preferably, the first bending plate, the reinforcing rib plate, and the second bending plate are all made of stainless steel.

[0011] The beneficial effects of this utility model are as follows:

[0012] By adding the speed governor bracket for machine-room-less elevators designed in this utility model, one end of the speed governor wire rope is fixed to the elevator car to maintain the same direction of operation; the other end runs in the opposite direction to the elevator car, maintaining sufficient running clearance and avoiding interference risks. This utility model is not only structurally reasonable, but also safer and more reliable, and is suitable for widespread promotion. Attached Figure Description

[0016] To enable those skilled in the art to more clearly understand the purpose, technical solution and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "horizontal", and "vertical" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0018] The present invention will now be described in detail with reference to the accompanying drawings: As shown in Figures 1-2, a speed governor bracket for a machine room-less elevator includes a speed governor bracket body. One end of the speed governor bracket body 1 is fixed to a vertically arranged shaft guide rail 4 by a pressure guide plate 2 and bolts 3. A speed governor 5 is fixedly installed at the upper end of the speed governor bracket body 1 by bolts. One end of the steel wire rope 6 in the speed governor 5 is fixed and runs in the same direction as the elevator car, while the other end of the steel wire rope 6 runs in the opposite direction to the elevator car, and a gap 7 is left between the steel wire rope 6 and the elevator car to prevent interference between the reverse-running end of the speed governor steel wire rope 6 and the elevator car components during elevator operation, which could cause the speed governor to malfunction.

[0019] As shown in Figure 3, the speed limiter bracket body 1 is composed of a first bent plate 8, a second bent plate 9, and two reinforcing ribs 14. Each of the first bent plate 8 and the second bent plate 9 has a corresponding mounting through hole 10. The first bent plate 8 and the second bent plate 9 are connected and fixed by bolts passing through the mounting through holes 10 of the first bent plate 8 and the second bent plate 9 in sequence. Two reinforcing ribs 14 with the same cross-section as the second bent plate are welded and fixed on opposite sides of the second bent plate 9.

[0020] The first bending plate 8 is bent outward at 90 degrees at both ends, forming a straight section 11 in the middle and bent sections 12 on both sides. The bent sections 12 on both sides have the same shape, making the first bending plate 8 have a C-shaped structure. The second bending plate 9 is bent outward at 90 degrees at both ends, forming a straight section in the middle and bent sections on both sides. The length of the upper bent section after bending is greater than that of the lower bent section, making the first bending plate have an inverted L-shaped structure. One corresponding mounting through hole 10 is opened on the straight section of the first bending plate 8 and the second bending plate 9. After the straight sections of the first bending plate 8 and the second bending plate 9 are tightly attached to each other, bolts are used to pass through the mounting through holes 10 of the first bending plate 8 and the second bending plate 9 in sequence to achieve the connection and fixation between the first bending plate 8 and the second bending plate 9. Multiple threaded through holes 13 are opened on the upper bent section of the first bending plate 8. Bolts are inserted into the threaded through holes 13 to achieve the connection and fixation between the speed limiter bracket body 1 and the speed limiter 5.

[0021] In the speed governor 5, one end of the steel wire rope 6 is located on the outer side of the first bending plate 8, near the shaft guide rail 4, and is fixed to the elevator car, running in the same direction. The other end of the steel wire rope 6 is located on the outer side of the second bending plate 9, away from the shaft guide rail 4, and runs in the opposite direction to the elevator car. This is to ensure that the speed governor steel wire rope 6 at the reverse running end does not interfere with the elevator car components. The first bending plate 8, the reinforcing rib plate 14, and the second bending plate 9 are all made of stainless steel.

[0022] For ease of understanding, a and b are marked in Figure 2. The speed governor wire rope on side a is close to the car and is connected to the car lifting mechanism. Its running direction is the same as that of the elevator car. The speed governor wire rope on side b is farther away from the car, thus increasing the safe operating space.

[0023] The speed governor wire rope of this utility model has a larger running gap with the end that runs in the opposite direction to the elevator car, which avoids interference and reduces safety risks; and through the design of this utility model, the speed governor can occupy less space and increase the product coverage.

[0024] The specific embodiments described herein are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
