Abstract
The utility model provides a disc type internal contracting brake for a tractor, which is characterized by comprising an internal contracting brake base, a brake disc 1 and a brake disc 2, wherein the internal contracting brake base is fixed on a shell support of the tractor by a positioning shaft, the brake disc 1 and the brake disc 2 are arranged on the internal contracting brake base by the positioning shaft, the brake disc 1 and the brake disc 2 can slide on the positioning shaft and are arranged opposite to each other, a brake flange of the tractor is arranged between the two brake discs, and the brake flange of the tractor is fixed on a driving spindle of the tractor. The disc type internal contracting brake adopts the disc type design instead of drum type design, overcomes the deficiencies of heavy weight and high material consumption, and also overcomes the deficiencies of high noise and slow motion simultaneously.
Description
Technical field:
The utility model relates to a kind of safety device that elevator traction machine starts and braking is special-purpose that is used for, and specifically relates to a kind of towing machine dish formula band-type brake.
Background technology:
The utility model is used for the device that elevator traction machine starts and braking is special-purpose, and original startup and brake equipment generally adopt the drum-type band-type brake, has that consumptive material is many, volume is big, noise is heavy, a defective more than the heavy, fault; Along with development of modern science and technology, new requirement has been proposed the elevator band-type brake: safety factor height, highly sensitive, requirement such as noise is low, fault is low.
The utility model content:
The utility model patent is finished at above requirement design and the shortcoming that overcome original drum-type band-type brake.
The utility model solves the scheme that its technical matters adopts:
A kind of towing machine dish formula band-type brake, it is characterized in that, comprise the band-type brake pedestal, brake disc 1 and brake disc 2, the band-type brake pedestal is fixed on by fix shaft on the support of casing of towing machine, and brake disc 1 and brake disc 2 are installed on the band-type brake pedestal by fix shaft, and brake disc 1 and brake disc 2 can slide on fix shaft and be oppositely arranged, be provided with the brake disc of towing machine between two brake discs, the towing machine brake disc is fixed on the drive shaft of towing machine.
Preferably, brake disc 1 and brake disc 2 are fixed with some friction linings respectively towards the direction of brake disc.
Preferably, be provided with some stressed springs and magnet coil between band-type brake pedestal and the brake disc 1.
Preferably, friction lining is connected with brake disc 2 with brake disc 1 respectively by plus-minus screw.
Preferably, the band-type brake pedestal is provided with the spanner that declutches.
Preferably, stressed spring is totally 8.
Concrete working process:
Band-type brake: the fluid pressure type disc brake of principle of work of the present utility model and automobile is basic identical, but used power and structure and inequality.Startup that the utility model is created and closed power are the elastic force of stressed spring and the electromagnetic force of magnet coil.Under the normal circumstances, elastic force by stressed spring pushes brake disc 1 powerfully, make the friction lining of braking 1 and brake disc 2 be close to the towing machine brake disc, the brake disc locking, during design, lock torque is much larger than drive torque, be fixed on the drive shaft of towing machine because of brake disc again, therefore, towing machine is braked, and makes elevator safety ground out of service;
Open a sluice gate: when elevator need move, microcomputer sent to magnet coil and opens a sluice gate signal, and magnet coil gets electric, and electromagnetic force compresses stressed spring makes friction lining break away from brake disc, and elevator then brings into operation according to instruction; Plus-minus screw makes it to be tending towards best normality in order to adjust gap and the parallelism between friction lining and the brake disc; When the spanner that declutches has a power failure in order to elevator, manually declutch.Friction lining is in order to increase the friction moment and the service life of brake disc.
For solving the problem that original elevator band-type brake exists, the utility model changes drum-type and is designed to the design of dish formula, has overcome the defective that weight is big, consumptive material is many, has also solved big, the heavy-footed shortcoming of noise simultaneously; To less than 1.75m/s, the elevator of 1000kg is as long as a towing machine gets final product the locking towing machine with dish formula band-type brake, in order to improve the safety factor of elevator operation, every towing machine adopts plural towing machine with dish formula band-type brake at least, and safety factor is enhanced about more than once; Therefore the utlity model has the safety factor height, highly sensitive, noise is low, fault is low, the good effect of good reliability.
Description of drawings:
Fig. 1 is an integral structure scheme drawing of the present utility model;
Fig. 2 is declutch spanner and the position view of fix shaft in the utility model.
Among the figure: 1-band-type brake pedestal, the stressed spring of 2-, 3-magnet coil, 4-friction lining, 5-plus-minus screw, 6-brake disc, the 7-spanner that declutches, 8-brake disc 1,9-brake disc 2,10-fix shaft.
The specific embodiment:
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
A kind of towing machine dish formula band-type brake, it is characterized in that, comprise band-type brake pedestal, brake disc 1, brake disc 2 and brake disc, brake disc 1 and brake disc 2 are installed on the band-type brake pedestal, brake disc 1 is oppositely arranged with brake disc 2, is provided with brake disc between two brake discs, and brake disc is fixed on the drive shaft of towing machine, two brake discs are fixed with some friction linings respectively towards the direction of brake disc, are provided with some stressed springs and magnet coil between band-type brake pedestal and the brake disc 1.Friction lining is connected with brake disc by plus-minus screw.Also be provided with the spanner that declutches on the band-type brake pedestal.Totally 8 on stressed spring is to guarantee enough elastic force.
Specific embodiment described herein only is that the utility model is made casehistory.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
