Abstract
The invention relates to a mining chain cutter for a big chain of a coal mine underground scrapper, an anchor rod, reinforcements and steel cables in the field of anchor cables and the like. The mining chain cutter comprises a supercharger, a high pressure oil pipe and a cutter, wherein one end head of the high pressure oil pipe is connected with the supercharger; the other end head of the high pressure oil pipe is connected with the cutter; the cutter comprises a cutter body with a shearing port, an oil cylinder, a fixed tool body and a movable tool body; the fixed tool body is arranged on one side of an upper cutting port of the cutter body; the movable tool body is arranged on a piston rod of the oil cylinder and is arranged on the other side of the upper cutting port of the cutter body; the oil cylinder of the cutter is fixedly arranged on one side of the cutter body; a pair of shearing tool bodies is formed by the fixed tool body and the movable tool body at the shearing port of the cutter body; a protective cover is arranged above the fixed tool body and the movable tool body; and the protective cover is hinged on the cutter body on one side of the shearing port. The mining chain cutter has the advantages of saving resources, improving the cutting efficiency, reducing the labor intensity, resisting to the corrosion and the like.
Description
Technical field
The invention belongs to and shear the utensil class, be specifically related to employed mining chain cutting devices such as a kind of reinforcing bar that is used in the big chain of coal mine lower scraping plate machine, anchor pole, anchor cable class and cable wire.
Background technology
At present, the colliery mining face under mine has been realized mechanical coal mining, and wearing and tearing or unexpected fracture often appear in the big chain of down-hole scraper plate machine, and often the big chain length of scraper plate machine is improper during install machinery in the down-hole, needs intercepting.At present; Be that sawed-off by hand mode is sawed-off with big chain basically under coal mine, and general bar cutting equipment is inapplicable under coal mine, does not also meet mining safety standard requirement; Like various bar croppers; Manual so sawed-off labour intensity is big, and elapsed time is long, has seriously influenced the progress of Coal Production.
Summary of the invention
The objective of the invention is deficiency to above-mentioned prior art; Provide a kind of in light weight, volume is little, it is light to move, easy to operate, cut-off velocity is fast, safe and reliable, can effectively improve cutting efficiency and alleviate the mining chain cutting device of staff's labour intensity.
The present invention for realizing the technical scheme that above-mentioned purpose adopted is:
A kind of mining chain cutting device comprises booster and high-pressure oil pipe, and it also includes cutter, and a termination of said high-pressure oil pipe connects booster, and another termination connects cutter; Described cutter contains cutter body, oil cylinder, fixed cutter body and the movable cutter hub that has sheared edge; Described fixed cutter body is contained in the one side that cuts off mouth on the cutter body; Described movable cutter hub is contained on the piston rod of oil cylinder; And being contained in the another side that cuts off mouth on the cutter body, its cutter oil cylinder fixedly is loaded on cutter body one side; Constitute the pair of shear cutter hub by fixed cutter body and movable cutter hub at the sheared edge place of cutter body.Above on described fixed cutter body and the movable cutter hub, be provided with protective cover, on the hinged sheared edge of the protective cover place cutter body on one side.
The present invention compared with prior art has the following advantages:
1, because this chain cut is to utilize the existing emulsion power pack in down-hole to be pressure source, do not need to be equipped with in addition Hydraulic Station; Effectively saved resource;
2, otch of the big chain of every cut-out only needs 5 minutes time, raises the efficiency 24 times than manual sawed-off, has saved the time of changing chain widely; Improve cutting efficiency, alleviated labour intensity;
3, above cutter two cutter hub positions, protective cover has been installed, can has effectively been prevented and avoid cutter hub to occur unexpectedly bursting apart or cutting off the danger that thing moment ruptures and upspring and caused.
4, seal of the present invention adopts corrosion-resistant sealing, has avoided the corrosion of emulsion, has guaranteed service life, and the critical piece in booster and the cutter has all been selected high strength, material such as corrosion-resistant for use.
The present invention is mainly used in the fast shut-off of the big chain of coal mine scraper machine Φ 52 following high strength, also can be used for the cut-out of section bar, anchor pole, steel wire rope, bolt etc.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the cutaway view of booster among Fig. 1.
The specific embodiment
Like Fig. 1, shown in Figure 2, a kind of mining chain cutting device.A kind of mining chain cutting device comprises booster 1 and high-pressure oil pipe 2, and described booster mainly is made up of a large tank 10, small oil tank 11, control valve plate 12, flow direction control valve 13, one group of high pressure (stainless steel) oil pipe 14.This mining chain cutting device also includes cutter 3, and a termination of said high-pressure oil pipe connects booster, and another termination connects cutter; Described cutter contains cutter body 4, cutter oil cylinder 5, the fixed cutter body 6 and movable cutter hub 7 that has sheared edge; Described fixed cutter body is contained in the one side that cuts off mouth on the cutter body; Described movable cutter hub is contained on the piston rod 8 of cutter oil cylinder; And being contained in the another side that cuts off mouth on the cutter body, its cutter oil cylinder fixedly is loaded on cutter body one side; Constitute the pair of shear cutter hub by fixed cutter body and movable cutter hub at the sheared edge place of cutter body.Above on described fixed cutter body and the movable cutter hub, be provided with protective cover 9, on the hinged sheared edge of the protective cover place cutter body on one side.Described cutter oil cylinder is a kind of oil cylinder that back-moving spring is housed in oil cylinder.
The operation principle of the present invention and the course of work:
The operation principle of the used booster of this mining chain cutting device is to utilize the original emulsion power pack in down-hole as pressure source; Utilize the pressure of pumping plant that small oil tank is filled with liquid; Then through control valve plate switching stream to; The force large tank of pumping plant pushes the large tank piston rod in the small oil tank, makes the volume in the small oil tank reduce the pressure increase.Under the effect of flow direction control valve, it is flexible constantly to the small oil tank supercharging that large tank is come and gone.The termination of small oil tank connects cutter by high-pressure oil pipe, and oil after the supercharging is defeated by the cutter oil cylinder of cutter.Wherein, a cutoff tool is a fixed cutter body, and another is movable cutter hub, and movable cutter hub is installed on the cutter oil cylinder piston bar, and movable cutter hub also is used as the extrusion shearing cutter hub.When the oil pressure of booster supply promoted cutter oil cylinder piston forward action, two cutter hubs formed squeezed state naturally, under the situation of constantly supercharging, made the continuous extruding of extrusion shearing cutter hub and will cut off the thing cut-out.After cutting off, open relief valve, the spring of dress is return original position with piston in the oil cylinder, and two cutter hubs open naturally.
