During installation, a probe of the displacement sensor keeps appropriate distance from the other side of the braking support; the displacement sensor is correctly connected with an input interface of a programmable controller; an output interface of the programmable controller is correctly connected with the electromagnetic valve and an intermediate relay respectively; and the intermediate relay is correctly connected with the motor.
Description
Technical field
The present invention relates to the control mechanism of a kind of hydraulic mechanical band-type brake mechanism, particularly a kind of hydraulic mechanical band-type brake.Belong to the mechanical ﹠ electrical technology field.
Background technology
At present, on large-scale transportation weight-lifting equipments such as mine, construction trade, generally all adopt the hydraulic pressure block brake that equipment is carried out brake snub and stop after stable car.This class drg is to make push rod overcome compression spring by the direct motor drive hydraulic efficiency pressure system when declutching, the take-off the brake wheel.And during the brake wheel band-type brake, cut off the power supply of electrical motor, and hydraulic efficiency pressure system quits work, the hydraulic coupling disappearance push rod under, and brake shoe is brake sticking brake under action of the spring.Because equipment all is to be in the long-play operating mode, therefore, the work that the oil pump of hydraulic efficiency pressure system need not stop, not only waste certain energy, the more important thing is the major failures such as to cause damage in impeller that works long hours, thereby cause the mechanical braking lock to lose efficacy cisco unity malfunction.In the equipment normal course of operation, if occur hydraulic system fault suddenly, will make the unexpected band-type brake of wheel machine lock, brake for equipment just at high-speed cruising, may cause occurring grave accident.
Summary of the invention
The objective of the invention is to provide a kind of: stable performance, can guarantee device security braking and the stable control mechanism that stops, realizes a kind of hydraulic mechanical band-type brake of automation control.
Solving the technical scheme that its technical matters adopts is: a kind of control mechanism of hydraulic mechanical band-type brake includes brake bracket, cylinder component, Hydraulic Station and control setup; Cylinder component includes single acting oil cylinder, piston rod, orienting lug; Hydraulic Station includes electrical motor, Hydraulic Pump, by pass valve, electromagnetic valve, fuel tank, check valve; Control setup comprises displacement pickup, programmable controller, displacement pickup is installed in a side of brake bracket by support, the probe of displacement pickup and the opposite side of brake holder keep suitable distance, and displacement pickup links to each other with the corresponding interface of programmable controller.The mouth of programmable controller links to each other with electromagnetic valve, intermediate relay respectively, and motor links to each other with programmable controller by intermediate relay.
Electrical motor links to each other with Hydraulic Pump by drive coupling, and the Hydraulic Pump oil suction links to each other with fuel tank, and the Hydraulic Pump oil discharge outlet links to each other with by pass valve, check valve; The by pass valve liquid return hole links to each other with fuel tank, and the check valve liquid outlet links to each other with the electromagnetic valve inlet with single acting oil cylinder respectively.The electromagnetic valve liquid return hole links to each other with fuel tank.
The present invention adopts the drive force source of single acting oil cylinder as mechanical brake, before device start, displacement pickup sends signal all the time, expression brake bracket brake shoe and brake wheel band-type brake, when device start, electromagnetic valve gets, the motor drives oil pump, moves on the cylinder body to the single acting oil cylinder oiling by check valve, progressively the both sides brake bracket is outwards strutted, after the both sides brake holder struts to a certain degree, displacement pickup stops to send signal, send the lock process to finish, and the electrical motor outage also is used for keeping the state that declutches of mechanical brake by the pressurize of check valve, make the transportation device normal operation, when the needs ramp to stop, the electromagnetic valve dead electricity, the fluid in the oil cylinder flows back to fuel tank by electromagnetic valve, under the effect of brake bracket upper spring power, the cylinder body of oil cylinder progressively moves down, reach certain stroke after, displacement pickup sends signal, brake shoe and brake wheel band-type brake, the equipment stopping-down.Under the sudden power situation, fluid flows back to fuel tank by electromagnetic valve, and the braking procedure during with orderly shutdown is just the same, and only after cylinder body moved down into specific stroke, displacement pickup did not send signal.
Beneficial effect: among the present invention owing to adopt displacement pickup that braking mode is monitored, can control in real time braking mode, the validity and the reliability of braking have been guaranteed, especially can avoid because brake equipment does not separate, or the harm of working parts are caused under the halfway situation.
