Abstract
The utility model provides a disk brake for monitoring the brake positive pressure in the state of brake, comprising a braking disc, a shoe plate, a scaleboard, a belleville spring, a connecting bolt, a brake seat, an oil hydraulic cylinder, an adjusting screw and a piston, wherein, a fastening body on the upper part of the scaleboard is a big groove, the bottom inside the groove is provided with a blind hole; the connecting bolt is of a shape like a Chinese character 'tu' and is provided with two lug bosses, the bottom of the lug boss is welded inside the blind hole on the bottom of the scaleboard, the middle part of the lug boss is provided with a tension sleeve with the bottom supporting the belleville spring, a sensor is arranged between the connecting bolt and the tension sleeve; the upper part of the connecting bolt is provided with a nut component. Because the brake is inside provided with the tension sleeve and the sensor, the positive pressure can be directly measured in the state of brake. The positive pressure multiplied by the friction coefficient and brake radius is equal to the brake torque; the size of the brake torque is monitored in real time, and whether the total brake torque is greater than three times of the maximum static torque is checked when a hoisting machine brake is completely braked. The utility model has a compact structure, high measuring accuracy and wide practicability.
Description
Technical field
The utility model relates to the disk type braker of monitoring braking positive pressure under braking state, is particularly useful for mine hoist and directly measures positive pressure under braking state, also is applicable to belt conveyor direct positive pressure of measuring under braking state.
Background technique
The mine hoist disk type braker produces brake positive pressure by butterfly spring, declutches by oil pressure.The Winder Disk Brake that at present domestic and international mine hoist generally uses all is to produce braking force by butterfly spring, declutches by oil pressure.Break oil pressure when braking is zero, relies on the precompressed active force of belleville spring, and brake shoe, liner plate, piston and attachment screw are pressed to brake disc together, as clamping brake disc, realizes braking.Be that pressure oil is fed piston cavity when declutching, belleville spring is compressed, brake shoe, liner plate, piston and attachment screw are moved to left leave brake disc and keep certain brake clearance.Regulation in " safe coal rules ", when lift braking device is braked fully, the total braking force square is greater than 3 times of maximum dead load moments, brake positive pressure is multiplied by friction factor and the stopping brake radius can obtain braking moment, and the Winder Disk Brake of using is measured brake positive pressure indirectly by oil pressure at present.According to break open a sluice gate with making process in oil pressure curve and brake clearance change curve, measure and to open, to paste the lock oil pressure, be converted into positive pressure again.Open a sluice gate oil pressure and be brake shoe and just left this oil pressure value in a flash of brake disc, the same lock oil pressure that pastes is that brake shoe rigidly connects and contacts this oil pressure value in a flash of brake disc, because oil pressure and brake clearance sensor measurement speed of response are different and oil pressure curve and brake clearance change curve that measure have irreqularity, so catch opening of being measured to, paste in lock oil pressure and the technology mensuration and differ bigger with what the clearance gauge and the scraps of paper were measured, be difficult to reach requirement on the precision, claim that this method is a kind of indirect method of measurement, also, can not directly measure brake positive pressure by oil pressure because oil pressure is residual voltage or zero under braking state.If can be under braking state directly measure brake positive pressure, in the time of can checking lift braking device on the one hand and brake fully the total braking force square whether greater than 3 times of maximum dead load moments, can monitor in real time on the other hand belleville spring tired with situation such as fracture.
The model utility content
The purpose of this utility model is the deficiency that exists according to prior art, and a kind of compact structure is provided, the measuring accuracy height, can be directly at the disk type braker of monitoring braking positive pressure under braking state.
Disk type braker of the present utility model comprises brake disc, brake shoe, and liner plate, butterfly spring, attachment bolt, the break seat, oil hydraulic cylinder, adjusting screw rod and piston, described liner plate top buckling body is a big groove, the groove inner bottom part has a blind hole; The described attachment bolt body of rod is native font, two boss are arranged, the bottom boss is welded in the blind hole of liner plate bottom, concordant with liner plate big groove bottom surface, the middle part boss is provided with the sleeve that bears that butterfly spring is held in the bottom, bears between the boss of sleeve bottom end face and attachment bolt bottom and leaves gap △; Attachment bolt and bear and be provided with sensor between the sleeve; Screw thread one end of attachment bolt passes piston, which is provided with the nut assembly that is fixed.
The described gap △ that bears between sleeve bottom end face and the attachment bolt bottom boss is 2mm; Described sensor is made of tension strain sheet and pressure-strain sheet, and the tension strain sheet is attached to and bears on the sleeve lining, and the pressure-strain sheet is attached on the attachment bolt; Described nut assembly is made of coupling nut, lock washer and retainer nut.
The beneficial effects of the utility model: owing to changed the brake inside structure, and be provided with in inside and bear sleeve and sensor, can under braking state, directly measure positive pressure, be multiplied by friction factor by gained positive pressure data and can obtain braking moment with the braking radius, whether the total braking force square was greater than 3 times of maximum static moments when the lift of the size of brake monitoring moment, and checking computations in real time braking device was braked fully.Brake positive pressure is that belleville spring applies, and therefore can monitor the situation that belleville spring is tired and rupture by sensor, also is used to test time lag simultaneously.Its compact structure, rationally distributed, easy to implement, the measuring accuracy height has practicability widely.
