Abstract
The built-in double-arm braking structure of the tractor belongs to the technical field of manufacturing of the tractor in an elevator system, and mainly comprises a machine body (4) with a brake (1) at the upper part, a middle notch (5) arranged in the middle of the two sides of the machine body (4), a hoop rod (7) embedded in the middle notch (5), a brake pad seat (6) with a brake pad (10) arranged in the middle of the hoop rod (7), a spring guide rod (3) with a spring (8) arranged at the upper part of the machine body (4), and the like. The middle notches of the built-in hoop rods are formed in the middle of the two sides of the machine body, so that the structural design of a braking system of the traction machine is more reasonable, the brake pads on the hoop rods brake at the middle notches of the machine body, unilateral braking is avoided, lateral deformation which is possibly caused by unilateral braking in the prior art is prevented, and the safety of an elevator is ensured.
Description
Technical field
The utility model relates to a kind of built-in type double-arm brake structure of tractor, belongs to the manufacturing technology field of towing machine in the elevator device.
Background technology
The towing machine that uses in the existing elevator device all is positioned over the anchor ear bar front of body.When extraordinary circumstances such as elevator generation emergency brake, the anchor ear bar is subjected to very big impulsive force, and instantaneous deformation takes place easily, and also gross distortion of brake facing this moment causes phenomenon influence brakes such as the not enough or one side brake of braking force.Impulsive force is big, and brake facing also might come off, and the easy driving of elevator, rushes to summit, squats at the end etc., and this structure has brought hidden danger for the safety of elevator.
Summary of the invention
The purpose of this utility model provides a kind of reasonable in design, can effectively improve the steady reliability of braking, guarantees the built-in type double-arm brake structure of tractor of elevator safety.
The utility model is a built-in type double-arm brake structure of tractor, the body that comprises the top band brake, the middle part, two sides that it is characterized in that body offers median slot, be embedded with the anchor ear bar in the median slot, the middle part of anchor ear bar is provided with the brake bar of belt brake sheet, the bottom of body is fixed in by the bar locating dowel pin in the bottom of anchor ear bar, and top is connected with drg by push rod.
Described brake bar can be connected with bolt by the seat locating dowel pin with the anchor ear bar.
The top of described body also can be provided with the spring guide of band spring, and an end of spring places outside the anchor ear bar.
The utility model is by offering the median slot of built-in anchor ear bar at the middle part, two sides of body, make the brake system structure design of towing machine more become reasonable, brake facing on the anchor ear bar is braked in the body median slot, stop one side brake, prevented the contingent lateral deformation of prior art one side brake; Brake bar and captiveing joint of anchor ear bar guarantee that braking is steadily reliable, can also prevent that brake facing from rupturing or when coming off, braking function still can not lose efficacy, and guarantees the safety of elevator.
Description of drawings
Fig. 1 is a construction profile scheme drawing of the present utility model;
Fig. 2 is Facad structure of the present utility model and part sectional view.
The specific embodiment
The utility model is mainly by the body 4 of top band brake 1, be opened in the median slot 5 at middle part, body 4 two sides, be embedded at the anchor ear bar 7 in the median slot 5, place the brake bar 6 of anchor ear bar 7 middle part belt brake sheets 10, place spring guide 3 formations such as grade of body 4 top band springs 8.The bottom of body 4 is fixed in by bar locating dowel pin 13 in the bottom of anchor ear bar 7, and top is connected with drg 1 by push rod 2; Brake bar 6 is captiveed joint with bolt 12 by seat locating dowel pin 11 with anchor ear bar 7; One end of spring 8 places outside the anchor ear bar 7.
During installation, earlier brake facing 10 usefulness glue are bonded on the brake bar 6, then brake bar 6 usefulness seat locating dowel pin 11 and bolt 12 are fixed on the anchor ear bar 7, make the position of brake bar and anchor ear bar certain.Again body 4 bottoms that install rotor core 9 are fixed in anchor ear bar 7 bottoms that have the bar 6 that brakes with bar locating dowel pin 13.Adjust brake facing 10 with special tooling, the brake facing 10 and the break-in face of rotor core 9 cylindricals are reached more than 75%.Brake facing directly acts on the rotor core 9, and its effect is that friction bowl iron core cylindrical is embraced towing machine, makes it stall.Again the push rod 2 that is with anchor ear bar 7, spring guide 3 and spring 8, drg 1 etc. are loaded onto.The effect of drg 1 is according to instruction unpack or closed brake equipment, makes towing machine according to instruction operation.
During use, give the order of drg 1 energising or outage by instruction.The thrust of drg 1 is on push rod 2 during energising, makes push rod 2 drive anchor ear bars 7 outer moving, make simultaneously on the spring guide 3 spring 8 by compression; The moving brake of the outer shipper pole of anchor ear bar 7 bar 6 grades are moved outward, make brake facing 10 leave rotor core 9 surfaces, and elevator normally moves.Drg 1 no thrust during outage, the screen resilience on the spring 8 make the state before anchor ear bar 7 recovers energising, and the towing machine rotating speed drops near zero-speed, brake facing 10 and rotor core 9 cylindrical friction brakinges, and elevator stops.Above process is the state of elevator when normally moving.But also may run into the various emergencies that can not preset in that elevator is in service.Such as emergency brake, promptly in the running process of elevator, anchor ear bar 7 is directly embraced on rotor core 9, and the sassafras that rubs by brake facing 10 and rotor core 9 cylindricals makes elevator out of service fully.At this moment anchor ear bar 7 is stressed very big, if anchor ear bar 7 can cause lateral deformation in body 4 fronts, causes phenomenons such as one side brake, makes brake not firm.Star-crossed words, brake facing also can rupture or come off, the forfeiture braking function.
