Abstract
The utility model provides a switching -over valve operating mechanism, includes handle and handle cover, round pin axle, lid and briquetting, places the spring in the handle, and the spring withstands the steel ball, and the camshaft embolias the handle, and in the steel ball part was in the pit of camshaft, two briquettings were set up in the camshaft both sides with circlip by round pin axle and axle respectively. The switching -over valve is used for the comprehensive face hydraulic bracket that adopts in colliery.
Description
Technical field
This utility model is related to a kind of commutation valve operating mechanism, refers in particular to one kind and props up for coal mine fully-mechanized mining working hydraulic pressure
The operating mechanism of the reversal valve on frame.
Background technology
Chinese patent once disclosed a kind of operating mechanism of reversal valve (201310268710.8), including pedestal, Handleset
And control assembly, control assembly is arranged in pedestal, and Handleset includes handle, overcoat and hold-down mechanism, and overcoat is from handle
Lower end is inserted in, and the lower end of overcoat is installed with connector, and overcoat is flexibly connected with control assembly by connector, hold-down mechanism
It is arranged in overcoat, the lower end of handle is provided with insertion rod, pedestal is arranged fluted, in the presence of hold-down mechanism, insertion
Bar passes through connector and extend in the middle of groove, and when handle is raised, and insertion rod leaves groove, handle can be pulled by left and right
Dynamic；Advantage is to need to carry handle upwards, after making insertion rod depart from groove, just can pull handle and be operated, it is to avoid because not
Carefully encounter generation maloperation, simultaneously because groove is deeper, the chute that handle stays on pedestal does not interfere with operating mechanism
Normal use, extends the service life of operating mechanism.
The reversal valve that Chinese patent once disclosed a kind of valve operating mechanism and included this valve operating mechanism
201220482543.8), wherein, described valve operating mechanism includes shifting component, bearing pin and handle, described shifting component and described
Bearing pin is located in the valve body of described valve, and described bearing pin is rotatably installed on described valve body, and one end of described bearing pin is located at institute
State the outside of valve body, described shifting component is connected with the valve element of described valve and described bearing pin respectively, and one end of described handle can
On described one end that multiple diverse locations of the circumference of described bearing pin are removably sleeved on described bearing pin.Grasped by above-mentioned valve
Vertical mechanism, can easily manipulate valve element, realize commutation；And the operational requirements of the person that disclosure satisfy that different operating, meet man-machine
Function assessment requires.
Chinese patent once disclosed a kind of operating mechanism of reversal valve (201320382914.X), including pedestal, Handleset
And control assembly, control assembly is arranged in pedestal, and Handleset includes handle, overcoat and hold-down mechanism, and overcoat is from handle
Lower end is inserted in, and the lower end of overcoat is installed with connector, and overcoat is flexibly connected with control assembly by connector, hold-down mechanism
It is arranged in overcoat, the lower end of handle is provided with insertion rod, pedestal is arranged fluted, in the presence of hold-down mechanism, insertion
Bar passes through connector and extend in the middle of groove, and when handle is raised, and insertion rod leaves groove, handle can be pulled by left and right
Dynamic；Advantage is to need to carry handle upwards, after making insertion rod depart from groove, just can pull handle and be operated, it is to avoid because not
Carefully encounter generation maloperation, simultaneously because groove is deeper, the chute that handle stays on pedestal does not interfere with operating mechanism
Normal use, extends the service life of operating mechanism.
But the operating mechanism being used at present is fished because leading to its life-span not reach wanting of new nation's standard due to its structure etc.
Ask.
Utility model content
The purpose of this utility model is to provide a kind of commutation valve operating mechanism, improves service life, reaches new nation's mark
Accurate requirement.
For reaching above-mentioned purpose, the solution that this utility model is taken is：A kind of commutation valve operating mechanism, including handle
And its taper knob, bearing pin, lid and briquetting, place spring in handle, spring withstands steel ball, and cam sleeve enters handle, steel ball part
It is in the pit of camshaft, two pieces of briquettings are arranged on camshaft both sides by bearing pin and its circlip for shaft respectively.
The contact angle of described briquetting does circular arc and processes.
Described cam sleeve enters handle, is provided with pad between handle and camshaft.
Described lid is by resilient key pin on handle.
This kind of commutation valve operating mechanism compared with prior art, has the advantages that：Through to cam and rotating shaft
Disjunctor designs, and increases the intensity of part, and the contact angle of briquetting is done circular arc process, makes briquetting and cam when relatively rotating
Can smooth transition, reduce impact, improve service life, reach the requirement of new nation's standard；Cam is become one with pivot design
Individual entirety, eliminates the rigging error originally producing because threaded, improves positioning precision；Situation in proof strength
Under, the overall dimensions of lid are relatively small, can reduce foundry goods materials.
