Description
Technical field
The invention belongs to underground coal mine custodial care facility field, especially relate to a kind of mining hand selector valve control gear.
Background technique
The application of hydraulic support, solves the difficulty that traditional coal cutting roadway needs to place back timber and guard beam.By hydraulic support stand, ensure coal winning machine mechanical mining, substantially increase coal mining efficiency.Along with the extensive application of hydraulic support, the action that moves forward into of normally following coal winning machine for guarantee hydraulic support is done, and needs to be controlled by the jack of hydrovalve to hydraulic support.The hydrovalve of current hydraulic control supporting position action divides two kinds, and one is hand-operated direction valve, and another kind is electric-hydraulic control reversing valve.The former needs the hand-operated direction valve of operator to every platform hydraulic support to carry out Non-follow control, and the latter can be controlled automatically by electrohydraulic control system.Because the latter's electric-hydraulic control reversing valve is emerging product, and structural principle and hand-operated direction valve inconsistent, what current most of colliery adopted is hand-operated direction valve.The shared in use cost of labor of hand-operated direction valve is very large, and the rugged environment simultaneously residing for coal mining, also have very large hidden danger for personal safety.So change hand-operated direction valve into automatic diverter valve, be the most effective way realizing coal mine work area high-yield and high-efficiency,
No matter current hydraulic support hydrovalve is hand-operated direction valve or electric-hydraulic control reversing valve, its structure is divided into valve body and driving mechanism composition, by conducting and the shutoff of driving mechanisms control valve body, makes flow of fluid, realize Jack of Hydraulic Powered Supports action, thus make hydraulic support action.Because hand-operated direction valve is all different with driving mechanism structure principle from the valve body of electric-hydraulic control reversing valve, if causing changing hand-operated direction valve is that valve body and driving mechanism must all be changed by electric-hydraulic control reversing valve.So it is very large hand-operated direction valve to be replaced with the cost that automatic diverter valve produces, be unfavorable for the renewal of hand-operated direction valve, so that cause the automation control system because of hydraulic support to promote to be obstructed and the present situation that mine automation exploitation realizes cannot be reached.
Therefore, how to design a kind of cost low, and hand-operated direction valve can be changed just directly can be installed on hand-operated direction valve the problem that the automatic controller automatically controlling hand-operated direction valve commutation becomes those skilled in the art's research.
Summary of the invention
In view of this, the present invention is intended to the mining hand selector valve control gear proposing a kind of low cost, need not change hand-operated direction valve, is directly installed on hand-operated direction valve and can realizes the automatic object controlled of hand-operated direction valve commutation.
For achieving the above object, technological scheme of the present invention is achieved in that
A kind of mining hand selector valve control gear, comprise electric signal interface, electromagnet, control valve, pressure cylinder and drive link, described electric signal interface connects externally fed power supply, described electromagnet is by receiving the break-make of electrical signal, carry out adhesive or disconnect described control valve, the displacement that described control valve is produced by adhesive and the disconnection of described electromagnet controls certain medium and passes in and out described pressure cylinder, described pressure cylinder by the turnover of described medium produce pressure difference drive described drive link to carry out action, described drive link controls hand-operated direction valve commutation.
Described medium is liquid.
Described medium is gas.The selection and comparison of medium of the present invention is various.
Described drive link controls the contact of hand-operated direction valve.Because the pressure ratio of liquid is comparatively large, contact is controlled than being easier to.
Described drive link controls the handle of hand-operated direction valve.Because the pressure of gas is smaller, handle is controlled than being easier to.
Described electric signal interface meets IP54 and above security level requirement.Improve the Security of underground work.
Described medium is introduced by the hydraulic system of hydraulic support.Directly utilize the original hydraulic system in colliery, save a set of hydraulic system, cost-saving further.
When described control gear does not carry out work, original driving mechanism still can control manual reverse of direction valve events.
Be provided with the hand-operated direction valve of above-mentioned control gear.
Relative to prior art, mining hand selector valve control gear of the present invention has following advantage:
(1) mining hand selector valve control gear of the present invention is directly installed to the automatic control that hand-operated direction valve can realize hand-operated direction valve, and need not change hand-operated direction valve, cost is low; Automatically control to save labour cost simultaneously, improve personal safety; Effectively can also improve coal mine work area coal mining efficiency.
(2) sensor device of the present invention comprises the parts such as electric signal interface, electromagnet, control valve, pressure cylinder and drive link, and structure is simple, and cost is low.
