Description
Technical field
The present invention relates to elevator, specifically cage type elevator brake unit.
Background technology
nullNow skyscraper be unable to do without cage type elevator，Although cage type elevator can provide great convenience to people，But safety is most important，Cage type elevator is played braking action by the brake unit of cage type elevator exactly，What the brake unit of existing cage type elevator used more is electromagnetic brake formula brake structure，This electromagnetic brake formula brake structure，It is exactly to utilize magnet control electromagnetic core action，Thus drive brake arm to carry out holding tightly or the action of take-off the brake wheel，But in use，The brake rubber block being contained on brake shoe is easy to wear，Must change when brake rubber block may wear to a certain degree，In order to change brake rubber block in time，The brake rubber block degree of wear need to be had gained some understanding grasp，The method used at present is to pass through manually to carry out scene check when repair and maintenance and estimate，Decide whether to change brake rubber block，Check due to scene and estimate and there is bigger error，And it is likely to be due to the carelessness of reviewer，Change the most in time when causing changing brake rubber block，So，It is possible to have an accident because of ineffective can not the braking in time of band-type brake.
Summary of the invention
It is an object of the invention to provide a kind of novel structure, control is accurate, can point out warning, convenient for installation and maintenance, safe and reliable, the cage type elevator brake unit of length in service life in time.
nullFor reaching above-mentioned purpose，The present invention includes frame、Electric magnet、Electromagnetic core、Two band-type brake assemblies being symmetrically set in two ends about electromagnetic core、Lower dolly bar and braked wheel，Also include negative loop electric wire、Electric bell、Alarm lamp、Positive wire and cathode conductor，Described band-type brake assembly includes brake arm、Brake shoe、Brake rubber block and brake rubber block abrasion detection assembly，Described brake rubber block is provided with blind hole，Described brake rubber block abrasion detection assembly includes compression spring、Plastic screw、Plastic sheath and conducting metal stepped stem，The centre of described plastic screw is provided with stairstepping through hole，The right-hand member of described conducting metal stepped stem is provided with tip，The upper end of the brake arm of described two band-type brake assemblies is loaded on left and right two end of the electromagnetic core of electric magnet respectively，The lower end of the brake arm of described two band-type brake assemblies is connected by lower dolly bar，Near the side of braked wheel equipped with brake shoe on the brake arm of described each band-type brake assembly，And equipped with brake rubber block on brake shoe，Described plastic sheathed is in the hole of brake arm，Described compression spring is threaded onto the left part of conducting metal stepped stem，And be loaded in the stairstepping through hole of plastic screw，Described plastic screw is connected with plastic sheath by screw thread，The tip of described conducting metal stepped stem right-hand member inserts in the blind hole of brake rubber block，The left end of described conducting metal stepped stem is connected with negative loop electric wire，Described cathode conductor is connected with braked wheel，One end of described electric bell and alarm lamp is all connected with positive wire，The other end of described electric bell and alarm lamp is connected with negative loop electric wire；The degree of depth of the blind hole of described brake rubber block is equal to the difference corresponding to the original thickness at blind hole and the safe wear-thickness of brake rubber block on brake rubber block.
Due to the fact that and have employed by compression spring, plastic screw, plastic sheath and the brake rubber block abrasion detection assembly of conducting metal stepped stem composition, and have employed by negative loop electric wire, electric bell, alarm lamp, positive wire and the reminding alarm device of cathode conductor composition, so, when brake rubber block wears up to the blind hole of brake rubber block, conducting metal stepped stem connects with braked wheel, owing to cathode conductor is connected with braked wheel, just cathode conductor can be made to connect with negative loop electric wire, now, the circuit of electric bell and alarm lamp is all switched on, electric bell sends warning the tinkle of bells, alarm lamp then luminous alarm.Present configuration is novel, controls precisely, can point out warning in time, and convenient for installation and maintenance, safe and reliable, service life is long.
