Abstract
The utility model belongs to hydraulic control systems of coal mine ore drilling equipment, and particularly relates to a trip linkage control hydraulic control system. The trip linkage control hydraulic control system comprises a linkage conversion valve, wherein oil pumps are connected with a linkage conversion valve to drive a feeding oil cylinder. According to the trip linkage control in a hydraulic system, through the addition of the linkage conversion valve, the linkage manner of a hydraulic clamping plate and a feeding rising oil cylinder, as well as the linkage manner of a clamp holder and the feeding rising oil cylinder can be changed; when a linkage conversion valve handle is arranged at the trip position, the feeding oil cylinder feeds, accordingly, the clamping plate can automatically tighten, and the clamp holder can automatically loose; when the linkage conversion valve handle is arranged at the trip-out position, the feeding oil cylinder feeds, accordingly, the clamping plate can automatically loose, and the clamp holder can automatically tighten; one operation of the feeding rising oil cylinder can finish the coordination of three actions, so that the work efficiency is greatly improved; the possibility of misoperation is avoided.
Description
Technical field
The utility model belongs to the hydraulic control system of colliery boring the ground equipment, is specifically related to the hydraulic control system that a kind of interlock that makes a trip is controlled.
Background technique
Coal mine drilling machine adopts revolution and feeds the double pump open-circuit hydraulic system of fuel feeding respectively, and after motor start-up, main oil pump is through oil purifier, stop valve oil suction, and auxiliary oil pump is through oil purifier oil suction, and output high pressure oil enters the action of operating table driving arrangement.In prior art, unclamping and clamping action of chuck, clamp holder need to separately be controlled by different handles, and working efficiency is lower, and easily occurs the phenomenon of misoperation.
Summary of the invention
It is high that the purpose of this utility model is to provide a kind of efficiency, the hydraulic control system that the interlock that makes a trip in the high hydraulic system of operational reliability is controlled.
In order to solve the problems of the technologies described above, the technological scheme that the utility model is taked is as follows:
The hydraulic control system that the interlock that makes a trip is controlled, is characterized in that: comprise an interlock changing valve, oil pump is connected driving with interlock changing valve and feeds oil cylinder; Described oil pump comprises main oil pump and auxiliary oil pump; Described interlock changing valve is three-position four-way valve, and wherein, one is the interlock of lower brill, and interlock changing valve handle is placed in lower brills, makes to feed oil cylinder and feeds that corresponding chuck will step up automatically, clamp holder unclamps automatically;
One is the interlock that pulls out of hole, and interlock changing valve handle is placed in the position that pulls out of hole, and now makes to feed oil cylinder and feeds that corresponding chuck will unclamp automatically, clamp holder steps up automatically;
Control interlock for one and lost efficacy, main oil pump and auxiliary oil pump are driven and are fed oil cylinder by multi-position reversing valve, interlock changing valve.
Beneficial effect:
The interlock that makes a trip in the hydraulic system that the utility model provides is controlled, by the increase changing valve that links, can change hydraulic disk and clamp holder and feed the oil cylinder interlock mode of pulling out, interlock changing valve handle is placed in lower brill position, feeding oil cylinder feeds corresponding chuck and will automatically step up, clamp holder unclamps automatically, interlock changing valve handle is placed in the position that pulls out of hole, now making to feed oil cylinder feeds corresponding chuck and will automatically unclamp, clamp holder steps up automatically, fed an operation of pulling out oil cylinder, just can complete the cooperation of 3 actions, greatly improved working efficiency, avoided the possibility of misoperation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, summary of the invention is done to detailed explanation.
With reference to Fig. 1, the utility model comprises an interlock changing valve, described interlock changing valve is three-position four-way valve, under one, bore interlock, interlock changing valve handle is placed in lower brill position, now making to feed oil cylinder feeds corresponding chuck 12 and will automatically step up, clamp holder 14 unclamps automatically, if make, feeding oil cylinder rises and pulls out corresponding chuck 12 and will automatically unclamp, clamp holder 14 steps up automatically, the interlock that pulls out of hole, interlock changing valve handle is placed in the position that pulls out of hole, now making to feed oil cylinder feeds corresponding chuck 12 and will automatically unclamp, clamp holder 14 steps up automatically, if make, feeding oil cylinder rises and pulls out corresponding chuck 12 and will automatically step up, clamp holder 14 unclamps automatically, controlling interlock for one lost efficacy, main oil pump 2 and auxiliary oil pump 9 are by multi-position reversing valve 8, interlock changing valve drives and feeds oil cylinder.
Interlock changing valve is three-position four-way valve, by this valve, can change chuck 12 and clamp holder 14 and oil cylinder 15 interlock modes, its interlock mode is: while making a trip, first interlock changing valve handle is placed in to relevant position (pulling out of hole or lower brill position), then only needs to operate the handgrip that makes a trip and can complete the action that makes a trip.When this valve is during in meta, its linkage function lost efficacy.
The stop valve 20 of connecting in clamp holder oil circuit, closes clamp holder oil circuit when creeping into or weighing, and clamp holder is stayed open, and is not subject to the impact of other actions.Fed and pulled out a loop pressure regulating overflow valve 16 in parallel, the throttle valve 18 of connecting, regulates pressure regulating overflow valve, can control feed pressure, and throttle valve 18 is connected in parallel with the Pilot operated check valve of pair of series.Can utilize if desired the back pressure that throttle valve produces that system pressure is improved, guarantee that clamp holder can open completely, avoid, lower brill is too low because of system pressure, clamp holder can not be opened completely, causes drilling rod to abrade.When gyrator does not drive drilling rod to move, two Pilot operated check valves are opened by controlling oil, so just have part fluid to flow through from one-way valve, have reduced the pressure loss.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
