Abstract
The utility model discloses a manual control valve of a hydraulic support for a fully-mechanized coal mining face. The manual control valve comprises a left support plate, a right support plate and a plurality of control valves, wherein the control valves are arranged between the left support plate and the right support plate; operating handles are connected to the control valves; a limit plate capable of moving leftwards and rightwards along the array direction of the operating handles is arranged on the control valves; a horizontal guide slot is formed in the limit plate along the array direction of the operating handles; a plurality of longitudinal guide slots are formed in the positions, corresponding to the operating handles, of the limit plate along the moving direction of the operating handles at intervals. The manual control valve of the hydraulic support for the fully-mechanized coal mining face has the advantages that the structure is simple, the use is convenient, the limit plate capable of leftwards and rightwards moving is arranged on the control valves, the limit function of the operating handles is realized by adjusting the position of the limit plate, the control valves are prevented from being touched accidentally, the malfunction of the support is prevented, and the whole operation process action is flexible and simple.
Description
Technical field
The utility model relates to the hydraulic support that fully mechanized coal mining face is used, and especially relates to a kind of fully mechanized coal mining face hydraulic support manual operation valve.
Background technology
The mostly direct knocking of the manual operation valve handle of China's coal-face hydraulic support used outside at present, and hydralic hose in coal face hydraulic support is encountered sometimes control valve handle when action, when walking between support, the personnel of work plane sometimes also can casually touch handle, these all may make support produce misoperation, have increased working face equipment and personnel's potential safety hazard.In order to stop the generation of this type of accident, be necessary control valve handle to take certain spacing measure.
Summary of the invention
The utility model object is to provide a kind of use safety, can carry out effectively spacing fully mechanized coal mining face hydraulic support manual operation valve to control valve handle.
For achieving the above object, the utility model can be taked following technical proposals:
Fully mechanized coal mining face described in the utility model hydraulic support manual operation valve, comprise left and right support plate and be arranged on the multi-disc control valve between described left and right support plate, on described control valve, be connected with control crank, on described control valve, be provided with along the limiting plate of control crank orientation side-to-side movement, on described limiting plate, along control crank orientation, offer horizontal guide groove, spaced apartly along corresponding each control crank position of the control crank direction of motion on described limiting plate be provided with a plurality of longitudinal guide grooves.
On described left support abutment plate top, be bolted junction plate, offered respectively the slot corresponding with limiting plate two ends on described junction plate and right support abutment plate, described limiting plate is movably arranged on control valve by slot.
The utility model advantage is simple in structure, easy to use, by on control valve, arrange can side-to-side movement limiting plate, utilize the adjustment of limiting plate position to realize the position-limiting action to control valve handle, thereby reach, prevent that control valve from being touched by mistake and causing support misoperation, whole operating process flexible movements, simple.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model normal operating conditions.
Fig. 2 is the structural representation of the utility model in spacing state.
The specific embodiment
As Fig. 1, shown in 2, fully mechanized coal mining face described in the utility model hydraulic support manual operation valve, comprise by left support abutment plate 1 and right support abutment plate 2 and be arranged on described left support abutment plate 1 and the multi-disc control valve 3 of 2 of right support abutment plates, on described control valve 3, be connected with control crank 4, on described control valve 3, be provided with along the limiting plate 5 of control crank 4 orientation side-to-side movements, installation for convenience of limiting plate 5, on described left support abutment plate 1 top, by bolt 6, be fixed with junction plate 7, on described junction plate 7 and right support abutment plate 2, offer respectively the slot corresponding with limiting plate 5 two ends, described limiting plate 5 is movably arranged on control valve 3 by slot, on described limiting plate 5, along control crank 4 orientations, offer horizontal guide groove, spaced apartly along control crank 4 corresponding each control crank 4 positions of the directions of motion on described limiting plate 5 be provided with a plurality of longitudinal guide grooves.During use, the position-limiting action to control crank 4 is realized in the position that changes limiting plate 5 by left and right, thereby reach, prevents that control valve 3 from being touched by mistake and cause support misoperation, whole operating process flexible movements, simple.
