Abstract
The utility model relates to a block-type electromagnetic brake, which comprises an armature plate, a coil, a spring, a sucking disc, a brake shoe, a brake bush and a hand-operated switching-off device, wherein the hand-operated switching-off device has the structure as follows: a big steel ball is arranged in a hole formed on the armature plate; a cam locks the big steel ball and fixes the big steel ball to the armature plate; a shaft stopping sleeve is arranged on the cam; small steel balls are arranged between the shaft stopping sleeve and the cam; a pull rod penetrates the brake shoe, the sucking disc, the armature plate and the cam; the spring is arranged at the top of the pull rod; a pull rod locking piece positioned at the bottom of the pull rod is locked on the shaft stopping sleeve through an inner hexagon screw; a shock pad is arranged on the sucking disc; a gasket is arranged at the upper part of the shock pad; and the gasket and the shock pad are fixed on the sucking disc through a bolt and a nut. The structure of a locking mechanism of the block-type electromagnetic brake is compact, and the operation of the brake is reliable; a damping system comprising the shock pad, the gasket, the bolt and the nut is installed on the brake so as to effectively reduce noise, and the gasket can be used in a circulating manner; moreover, the service life of the brake is prolonged, and the maintenance cost is lowered.
Description
Technical field
The utility model relates to a kind of towing machine direct solenoid control setup that is used for elevator, weight-lifting equipment, is a kind of magnet stopper specifically.
Background technology
Elevator is in operation and cuts off the power supply suddenly, and car can stop, and utilization at this moment can make car fall with the hands off system.Traditional hands off device adopts nut or screw lock, after opening a sluice gate test 1000 times, often takes place to exceed the stroke range of drg itself because block nut or screw loosening cause the cam stroke scope to increase, and loses and opens a sluice gate to act on.Be controlling noise in running process of elevator in addition, must take various glissandoes.Common hub type brake is owing to have a series of mechanical hatching gate structures such as brake control lever, and noise is subjected to structural limitations to be difficult to develop to high-precision end about 68dB.The tradition block brake generally adopts nonadjustable shock mitigation system, and generally about 68dB, after the wearing and tearing that work long hours, gap increase, noise also increase noise thereupon, and terms of settlement can only be to change drg.
Summary of the invention
In order to solve the problem of above-mentioned existence, the utility model provide a kind of locking effect good, can effectively avoid cam to become flexible phenomenon, reliable, and have the scalable shock absorption device, prolong the drg block type electromagnetic brake in service life.
The purpose of this utility model is achieved through the following technical solutions: block type electromagnetic brake, armature disc is connected by adjusting cover with sucker, on armature disc, be provided with the hands off device, the lock boots are installed on sucker, be provided with brake bush above the lock boots, be embedded with coil at armature disc, several springs are installed in armature disc, above armature disc, be provided with micro-switch operating mechanism, it is characterized in that: described hands off apparatus structure is: be placed with big steel ball in the hole of armature disc, cam blocks and is fixed on big steel ball on the armature disc, on cam, be provided with the gear shaft cover, be provided with little steel ball between gear shaft cover and the cam, pull bar passes the lock boots, sucker, armature disc, cam is provided with spring at the pull bar top, the pull bar lock dog of pull bar bottom is by socket head cap screw and gear shaft cover locking, be provided with cushion blocking on sucker, the cushion blocking top is provided with pad, by interior hexagonal flush end holding screw, nut is fixed on pad and cushion blocking on the sucker.
The beneficial effects of the utility model: the utility model adopts said structure, when the drg band-type brake, to open a sluice gate that spanner is enclosed within on the cam and firmly when pressing down, because the mutual locked constraint between pull bar lock dog and the gear shaft cover, the two can not be rotated, can avoid like this behind frequent hands off, because the loosening cam stroke scope increase that occurs that is threaded between gear shaft cover and the pull bar, the phenomenon that causes big steel ball to skid off in the pit of cam.The effect of socket head cap screw is to prevent coming off of pull bar lock dog, thereby guarantees that working of brakes is reliable; This locking mechanism structure compactness, hands off apparatus structure compactness, employing be locked mode, the mutual restriction between the parts makes it locked, even repeatedly open a sluice gate also can not occur the loosening phenomenon of cam.Constitute shock mitigation system by cushion blocking, pad, screw, nut, the cushion blocking height can be adjusted with interior hexagonal flush end holding screw, adjust the height of cushion blocking after.Be screwed into nut at the interior hexagonal flush end holding screw other end, lock whole shock mitigation system.This structural damping system is installed on drg, can effectively reduces noise, noise control (the actual measurement noise is at 48dB) below 50dB, drg acts directly on and reduces the intermediate mechanical structure on the brake wheel, effectively reduces noise.Shock mitigation system has adjustability simultaneously, the long-time use after the cushion blocking wearing and tearing, squeaking of the brakes increases, can unclamp nut, regulate interior hexagonal flush end holding screw, readjust the height of cushion blocking, adjust back damping scope, noise is the same with new product, cushion blocking can recycle, and increases drg service life, reduces maintenance cost.
