Abstract
The invention discloses a pulse brake applicable to ascending and descending drive devices, and relates to a brake. The brake is provided with a reduction box and a controller, the reduction box is connected with a motor through a coupling, a disc brake, a piston and a spring are sequentially mounted on a shaft between the reduction box and the coupling, the piston is connected with an electromagnetic brake valve, a speed sensor and a current detecting element are mounted on the motor, the controller is respectively connected with the speed sensor, the current detecting element and the electromagnetic brake valve. The pulse brake has the advantages that the descending speed of the devices can be stably controlled, faults such as overturn of the devices are avoided, and instant slip of the devices in the ascending process is prevented.
Description
Technical field
The present invention relates to a kind of break; It specifically is a kind of pulse break that is applicable to the uplink and downlink drive unit; Can be used for safety brake and break safety when up of drive units such as mine excavation machinery, enterprise's lifting appliance and mountain area cableway when descending and open, guarantee the brake safe of these equipment when descending and the clean boot when up.
Background technique
Many fields such as Modern Production and life; Need to adopt electric motor drive apparatus to carry out up (going up a hill) and descending (going down the hill); Like the mining machinery in mine, the lifting appliance of enterprise and the cableway in scenic spot mountain area or the like,, generally adopt hydraulic brake or electromagnetic brake to come equipment is braked for the safety of assurance equipment when the uplink and downlink; Hydraulic brake only works when equipment downtime, and break is opened when normally moving.And motor can produce tach signal and electric current (moment) signal when operation.
But there is following shortcoming when adopting break to brake,
1, equipment is when descending, because the sliding force that the deadweight of equipment produces, the downstream rate of equipment can be more and more faster, surpassed controlled speed, finally causes hauling speed uncontrollable;
2, equipment by static make progress in a flash up; If, can cause motor " vexed car ", if break is opened in advance because break is not opened in advance; Can cause the moment of equipment to glide so, thereby may bring beyond thought equipment and life injury.
Summary of the invention
In order to overcome the shortcoming of above-mentioned existing technology, the present invention provides a kind of pulse break that is applicable to the uplink and downlink drive unit, can realize that the speed safety of motor in the uplink and downlink process is controlled.
The present invention realizes with following technological scheme: a kind of pulse break that is applicable to the uplink and downlink drive unit; Comprise speed reducer; Speed reducer is connected with motor through coupling; On the axle between speed reducer and the coupling, disk type braker, piston and spring are installed successively, piston connects the brake solenoid valve; Velocity transducer and current measuring element are installed on motor; The controller that is connected with current measuring element with velocity transducer respectively, controller is connected with the brake solenoid valve.
It further is: described spring adopts butterfly spring.
Described brake solenoid valve adopts two-position four-way solenoid valve.
The invention has the beneficial effects as follows: can use fairly simple pulse braking method to realize; Controller can be through the sensor acquisition motor tach signal and electric current (moment) signal and utilize these signals to control the rotating speed of motor; When speed and torque reach certain numerical value; Controlling hydraulic brake declutches, brakes equipment: 1) the equipment downstream rate is steadily controlled, faults such as equipment topples can not occur; 2) prevent moment downslide phenomenon in the up process of equipment.

6, motor, 7, terminal box, 8, A.C. contactor, 9, velocity transducer, 10, current measuring element, 11, controller, 12, oil sump, 13, the brake solenoid valve.
Embodiment
As depicted in figs. 1 and 2; A kind of pulse break of uplink and downlink drive unit that is applicable to has a speed reducer 1; Speed reducer 1 links to each other with motor 6 through coupling 5, on the axle between speed reducer 1 and the coupling 5, disk type braker 2, piston 3 and spring 4 is installed successively; Motor 6 is through terminal box 7 and the A.C. contactor 8 external 380V power supplys that exchange; At motor 6 tail ends velocity transducer 9 and current measuring element 10 are housed also; Velocity transducer 9 and current measuring element 10 feed back to controller 11 with the rate signal and the current signal of motor 6, and controller 11 is compared feedback signal with predefined signal.The oil back chamber of brake solenoid valve 13 connects oil sump 12.
Wherein, spring 4 adopts butterfly spring, and brake solenoid valve 13 adopts two-position four-way solenoid valve.
Working procedure: disk type braker 2 is housed on speed reducer 1, and the coil of brake solenoid valve 13 gets electricly when proper functioning, gets into oil pockets from the high pressure oil of hydraulic system through two-position four-way brake solenoid valve 13; High pressure oil compression belleville spring; The axle of speed reducer 1 can rotate freely, when the needs skidding, and the coil losing electricity of brake solenoid valve 13; Belleville spring is braked through piston 3 and disk type braker hydraulic oil pressure oil return pond simultaneously with speed reducer.
Thereby solenoid valve 13 outages of will braking when reaching certain speed are braked in that equipment is descending, can make numerical control steadily controlled; When starting starting torque and reach certain numerical value, the solenoid valve 13 that will brake electric, can be placed on the in a flash downslide of equipment in startup.Thereby can support equipment safety and life safety.
