Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to a speed governor assembly for elevators. Background Technology

[0002] The elevator speed governor is a key safety control component in the elevator safety protection system. Its main function is to monitor and control the speed of the elevator car during operation to ensure the safe operation of the elevator.

[0003] Currently, some existing elevator speed governors rely on a braking component to compress the rope pulley on the speed governor, increasing frictional resistance to achieve braking. In this type of speed governor, the braking component is a consumable; as the usage time increases, the wear of the braking component gradually increases, weakening or even losing its braking effect. Therefore, it needs to be replaced regularly to ensure the effectiveness of the elevator speed governor. However, due to the high integration and limited internal space of modern elevator speed governors, replacing the braking component is quite complex, increasing the difficulty for users to replace the braking component and reducing the convenience and efficiency of the replacement operation, making it difficult to meet the needs of convenient use. Therefore, this paper proposes a speed governor component for elevators with an easily replaceable braking component. Utility Model Content

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] This utility model provides, for example Figures 1-4The speed governor assembly for an elevator shown includes a speed governor housing 100, a speed governor pulley 101 rotatably mounted inside the housing 100, a circular slot 102 formed on the end face of the pulley 101, a brake assembly positioned near the inner wall of the circular slot 102, a drive assembly mounted on the housing 100, and a tilting assembly positioned between the brake assembly and the drive assembly, with the brake assembly rotatably connected to the drive assembly via the tilting assembly. The horizontal driving action of the drive assembly moves the brake assembly towards the inner wall of the circular slot 102, causing the brake assembly to press against the inner wall of the slot 102, thereby achieving… The braking purpose is to control the pressure between the brake assembly and the inner wall of the circular slot 102, thereby adjusting the braking degree and reducing the speed limiter pulley 101 rotation. The flipping assembly not only connects the brake assembly to the drive end of the drive assembly, allowing the drive assembly to stably move the brake assembly, but also flips the brake assembly from the inner side of the circular slot 102 to the outer side of the speed limiter housing 100. This increases the space available for disassembling and replacing the brake assembly, allowing users to perform the disassembly and replacement in a larger space, thus improving the convenience and efficiency of the operation.

[0034] The brake assembly includes a brake element 108 and a connecting block 107. One side of the brake element 108 faces the sidewall of the circular slot 102. The connecting block 107 is located on the brake element 108 away from the sidewall of the circular slot 102. One end of the connecting block 107 is fixedly connected to the outer wall of the connecting seat 111. The connecting assembly is located between the brake element 108 and the connecting block 107. The brake element 108 is detachably connected to the connecting block 107 through the connecting assembly. The connecting assembly includes a brake seat. One end of the brake seat is fixedly connected to the brake element 108. The rod of the brake seat is stepped, and the end of the brake seat away from the brake element 108 passes through the sidewall of the connecting block 107 and is threaded with an assembly nut 109. The brake element 108... The brake element 108 is generally an integral part of the brake seat, but it can also be configured as a separate structure, allowing the brake element 108 to be detached from the brake seat. Then, in conjunction with the stepped shape of the rod on the brake seat, it can be inserted into the through hole at the end of the connecting block 107 to achieve a blocking and limiting effect. Finally, in conjunction with the mounting nut 109, the end position of the brake seat rod is connected and locked, so that the brake element 108 can be relatively fixed to the connecting block 107, while realizing the detachability of the brake element 108 from the connecting block 107. The brake element 108 moves and is squeezed into the inner wall of the circular slot 102 by the power provided by the drive assembly, increasing the frictional resistance between the two, thereby achieving the purpose of decelerating the speed limiter pulley 101.

[0035] The drive assembly includes a threaded rod 104, a servo motor 105, and a nut seat 106. A mounting notch 103 is provided at the top of the speed limiter housing 100 near the brake assembly. The threaded rod 104 is rotatably connected to the mounting notch 103. The servo motor 105 is fixedly connected to the outer wall of the speed limiter housing 100 and is drively connected to the threaded rod 104. The nut seat 106 is threaded onto the outer wall of the threaded rod 104, and its bottom is slidably connected to the bottom of the mounting notch 103. An annular groove 110 is provided in the middle of the outer wall of the nut seat 106, and a connecting seat 111 is rotatably fitted onto the nut seat 106. The annular slot 110 on the speed limiter housing 100 at the position of the speed limiter is convex outward on both sides of the mounting notch 103, increasing the mounting area of ​​the inner wall of the mounting notch 103. At the same time, the transmission connection between the servo motor 105 and the threaded rod 104 can be transmitted through two meshing gears. Since the bottom end of the nut seat 106 is flat and slides with the bottom of the inner wall of the mounting notch 103, it can achieve the limiting and guiding effect of the movement of the nut seat 106. When the threaded rod 104 rotates clockwise or counterclockwise, it can drive the nut seat 106 to translate along the axial direction of the threaded rod 104, thereby achieving the translational drive of the brake assembly.

[0036] The flipping assembly includes a connecting seat 111 and a locking structure. The side wall of the connecting seat 111 is fixedly installed with the brake assembly. The connecting seat 111 is rotatably sleeved on the moving end of the drive assembly. The locking structure is installed on the connecting seat 111 and the drive assembly, and is used to limit and lock the radial rotation of the connecting seat 111 on the drive assembly. An annular slot 110 is provided in the middle of the outer wall of the nut seat 106 to allow the connecting seat 111 to be rotated on the nut seat 106. To facilitate the installation of the connecting seat 111 at the position of the annular slot 110, the connecting seat 111 can be set as a split clamp structure. By rotating the connecting seat 111 at the position of the annular slot 110 on the nut seat 106, the connecting block 107 can drive the brake component 108 to flip, thereby flipping it to the outside of the speed limiter housing 100 for the installation and removal of the brake component 108 on the connecting block 107.

[0037] In a preferred embodiment, the locking structure includes a positioning protrusion 112, which is vertically fixed to the top of the side wall of the connecting seat 111. A threaded pin 113 is movably inserted into the middle of the positioning protrusion 112, and a positioning screw hole 114 is opened on the top of the nut seat 106 near the annular slot 110. The outer wall of the threaded pin 113 is threadedly connected to the inner wall of the positioning screw hole 114. When the brake component 108 is in the working position, the positioning protrusion 112 is located at the positioning screw hole 114 at the top of the outer wall of the nut seat 106. At this time, it is only necessary to insert the threaded pin 113 from the through hole on the positioning protrusion 112 into the positioning screw hole 114 and tighten it to lock and fix the position between the annular slot 110 and the nut seat 106, ensuring the stability of the connection between the brake component and the drive component.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
