Problems solved by technology

[0002] The elevator speed limiter is one of the safety control components in the elevator safety protection system. When the elevator is running for any reason, the car may overspeed or even fall, and all other safety protection devices do not work. If the overspeed limiter and the safety gear are linked, the elevator car will be stopped. However, the current elevator cannot remotely realize the functions of manual trigger braking, manual reset braking and manual remote reset of the electrical switch during running detection. Close operation is required, which will cause many safety hazards

Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] Such as Figure 1 to Figure 3 The machine-room-less elevator speed limiter shown includes a bracket 1, and a speed limiter switch 2 is installed on the upper part of the bracket 1. The speed limiter switch is provided with a reset screw 41 that drives the speed limiter switch to reset. The support 1 includes a bottom plate and the side wall, the bracket 1 is provided with a sheave assembly, the sheave assembly includes a sheave mechanism 3 and a ratchet mechanism 4 for winding the wire rope, a brake assembly is provided on one side of the sheave assembly, and includes The block assembly 15 hinged on the side wall is used to trigger the brake assembly to work. The sheave mechanism 3 is also provided with a pituitary assembly that drives the block assembly 15 to rotate. One side of the block assembly is provided with The drive rod 21 prot...

Abstract

The invention discloses a non-machine-room elevator speed limiter which comprises a support. A speed limiter switch is installed at the upper portion of the support. A reset screw driving the speed limiter switch to reset is arranged on the speed limiter switch. A rope sheave assembly is arranged in the support. A braking assembly is arranged on one side of the rope sheave assembly. The non-machine-room elevator speed limiter further comprises a stop block assembly which is hinged to the side wall and is used for triggering the braking assembly to work. A pendency body assembly is further arranged in the rope sheave assembly. A driving rod stretching out of a side plate is arranged on one side of the stop block assembly. The non-machine-room elevator speed limiter further comprises a mechanical triggering resetting mechanism driving the driving rod to move and an electrical resetting mechanism driving the reset screw to move so that a speed limiting switch can to reset operation. Whenthe non-machine-room elevator speed limiter conducts braking detection, even if the speed limiter does not exceed the limiting speed, remote triggering, resetting and other operation can also be conducted by manually pulling a brake cable, people do not need to get close to the speed limiter for operation, and therefore safety of braking detection is increased.

Description

technical field [0001] The invention relates to a speed governor for an elevator, in particular to a speed governor for an elevator without a machine room. Background technique [0002] The elevator speed limiter is one of the safety control components in the elevator safety protection system. When the elevator is running for any reason, the car may overspeed or even fall, and all other safety protection devices do not work. If the overspeed limiter and the safety gear are linked, the elevator car will be stopped. However, the current elevator cannot remotely realize the functions of manual trigger braking, manual reset braking and manual remote reset of the electrical switch during running detection. Close operation is required, which can cause many safety hazards. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a machine room-less elevator overspeed governor that can realize remote triggering and reset. [0004] The ...
