Speed limiter fixing seat

Abstract

According to the speed limiter fixing base, the bearing plate is used for bearing the speed limiter, the distance between the first connecting table and the second connecting table is adjusted according to the size of the speed limiter, and therefore the length, located between the first connecting table and the second connecting table, of the bearing plate is adjusted. And after the position of the second connecting table is adjusted, one end of the bearing plate is in threaded connection with the first bearing table through a plurality of bolts, and the other end of the bearing plate is in threaded connection with the second bearing table through a plurality of bolts. And in the process of adjusting the position of the second connecting table, the second connecting table is pushed to move in the sliding groove, so that the corresponding part of each ball is inserted into one sliding way and is in sliding connection with the bearing table. And the friction force between the second connecting table and the bearing table can be reduced through the balls arranged in all the semi-spherical cavities of the second connecting table, and the second connecting table can be conveniently moved. The speed limiter fixing seat can be adapted to speed limiters with different sizes, and the high heat dissipation requirement of the speed limiter can be met.

Description

Technical Field

[0001] The utility model relates to the field of speed limiter installation, in particular to a speed limiter fixing seat. Background Art

[0002] The elevator speed limiter is one of the safety control components in the elevator safety protection system. When the elevator car is overspeeding or even in danger of falling during operation for any reason, and all other safety protection devices do not work, the speed limiter and the safety clamp will work in conjunction to stop the elevator car. The elevator speed limiter is a safety protection device for the elevator. It monitors and controls the speed of the car at any time. When an overspeed occurs, it can send a signal in time, and then produce a mechanical action to cut off the power supply circuit and brake the traction mechanism. If the elevator still cannot brake, the safety clamp installed at the bottom of the car will act to force the car to stop. The speed limiter is the command issuer, and the safety clamp is the executor. The joint action of the two has led to the saying of safe elevators. The speed limiter safety clamp system is an indispensable safety device for elevators. When the elevator is overspeeding, out of control or the suspension device is broken, the speed limiter safety clamp device quickly stops the elevator car on the guide rail and keeps it stationary, thereby avoiding casualties and equipment damage.
