Abstract
The utility model discloses a reversing device of a manual braking electromagnetic device, which is used for realizing the reversing during power failure and comprises an electromagnetic coil (4) and an iron core (5), wherein the iron core (5) is internally provided with an ejector rod (3); one end of the iron core (5) is arranged on a valve body; the reversing device is characterized in that the other end of the iron core (5) is provided with a reversing screw support (7); a reversing screw hole corresponding to the ejector rod (4) is arranged on the reversing screw support (7) and is provided with a reversing screw (8); the reversing device has simple structure, realizes reliable movement, is low in cost and conveniently and effectively solves the problem that the fault dragging is difficult to realize when a vehicle with the electromagnetic valve as a manual braking control valve lacks of electricity.
Description
Technical field
The utility model relates to a kind of down-hole trackless mining vehicle breaking operation system, specifically a kind of hand braking electromagnetic valve reversing arrangement.
Background technology
Trackless mining vehicle in down-hole such as scoper, underground car has hand braking and foot brake two cover brake-operating systems more.Wherein, old-fashioned hand braking employing hand valve control, can pull handle when not having electricity makes it to declutch or brake, but when motor or driving engine have a power failure (stopping working) suddenly, can not implement the brake system automatic band-type brake, safety is affected, in addition, owing to need M/C, be difficult on intelligent scoper and underground car, use.Therefore, present general hand braking employing solenoid control, in case system's dead electricity, control system can be implemented brake sticking brake automatically, safety is good, and owing to be electric control operation, is specially adapted to the novel intelligent equipment of computer control.But, when vehicle breaks down, in the time of need dragging, if do not have electricity (failed vehicle does not generally have), then hand braking can't unclamping, vehicle can't be towed, if will tow, can only dismantle drg, or use other interim power supply, and work capacity is big, is difficult to realize.Therefore,, control new-type easily brake system, must solve how electromagnetic valve realizes reliable commutation when not having electricity problem for safe and reliable.
Summary of the invention
The purpose of this utility model provides a kind of electromagnetic valve is realized commutation when not having electricity hand braking electromagnetic valve reversing arrangement.
The utility model is to adopt following technical scheme to realize its goal of the invention, a kind of hand braking electromagnetic valve reversing arrangement, it comprises magnet coil, iron core, be provided with push rod in the iron core, one end is installed on the valve body, the iron core other end is provided with commutation screw bearing, and commutation screw bearing is provided with and the cooresponding commutation screw of push rod, and the commutation screw is provided with the commutation screw.
Owing to adopt technique scheme, the utility model has been realized goal of the invention preferably, it is simple in structure, reliable in action, with low cost, and is convenient, solved with electromagnetic valve and be difficult to realize that as the vehicle of hand braking control cock fault draws a difficult problem that tows when the short of electricity effectively.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of hand braking electromagnetic valve reversing arrangement, it comprises magnet coil 4, iron core 5, be provided with push rod 3 in the iron core 5, one end is installed on the valve body, iron core 5 other ends are provided with commutation screw bearing 7, and commutation screw bearing 7 is provided with and push rod 3 cooresponding commutation screws, and the commutation screw is provided with commutation screw 8.
When the utility model was not switched on when magnet coil 4, spool 2 was in right positions under the promotion of spring 1, and this moment, drg was in braking mode, and vehicle can not be walked.Break down need tow the time at vehicle, the screw 8 that will commutate screws in, and promotes spools 2 by push rod 3 and overcomes the spring force left lateral, makes electromagnetic valve realize not having the electricity commutation, removes hand braking.
Vehicle just often, commutation screw 8 screws out and does not contact with push rod 3, when magnet coil 4 must be electric, electromagnetic force made push rod 3 overcome spring force, makes spool 2 be in leftward position, (drg is in the state of declutching, vehicle can cruising or fault tow.
