Description

One splits rock device

Technical field

The utility model relates to mining mechanical field, particularly relates to a kind ofly to split rock device for what exploit rock.

Background technology

Along with development, the progress of society, after the invention of the Iron Age and gunpowder, people just adopt and punching on rock, and then explosive in hole, after ignition blows basement rock.Adopt this scheme, mine worker labour intensity is large, and produce dangerous, extraction operation is unordered, and disorderly dig disorderly fried, non-renewable precious resources is wasted very large.And when using automated machine equipment to carry out mining, cost is too high, require also very high to the operating technology of workman.

Hubei Research-Design Inst. of Building Material Ind. has applied for the patent of invention of " a kind of tool for grooving in hole " by name on March 12nd, 89, adopt this instrument on basement rock, dig out several deep holes of φ 40, a pair trough is mechanically carved equably in each hole, trough is directive, in hole, fill up flame detonator, aperture is by the good yellow mud compression of caking property, compacting.After electric signal igniting, basement rock squeezes by the gases at high pressure producing stress concentrated along the direction of trough in hole wall.The program drops into seldom, and effect is fine, is the preferred version of the waste material of cutting on basement rock.But the program still can use the dangerous material such as gunpowder, so safety in production aspect need to improve.

The normal scheme adopted also has static expanding agent method at present, first being holed by explosion material object, installing water, being then poured into water by medicament, then stir into a paste with bucket.Slowly pour in hole, till filling, need not cover, need not mouth be filled in.After powder charge, get final product natural cracking through 8 hours explosion things.This scheme utilizes the chemical reaction of medicament to produce the huge bulbs of pressure and is pushed open by basement rock, because chemical reaction needs certain action time, so can not apply in time, and expansion agent is in the process of shipping storage and use, if misoperation, also there is certain danger.

Utility model content

The utility model is solve the technical problem that such scheme exists, and provides one not adopt chemical method just can realize Rock cutting, and can split rock device according to requirement of engineering orientation cutting of fixed quantity rock.

For achieving the above object, the utility model adopts following technical scheme: one splits rock device, comprises cylindrical body, multiple piston, the first oil nozzle; Described cylindrical body is provided with multiple cell body, and described piston is arranged in cell body, and the piston top of piston and the inwall of cell body are slidably matched, and with cell body bottom form the first cavity volume; The bottom of described cell body by the first oil circuit with for being communicated with to the first oil nozzle of delivering oil in the first cavity volume.

As preferably, the opening part of the cell body that described cylindrical body is arranged also is provided with the fairlead for limiting piston scope of activities, and described fairlead is placed on the piston head of described piston, and forms the second cavity volume with the piston top of piston.

As preferably, described cylindrical body is also provided with the second oil nozzle of delivering oil in the second cavity volume, described second oil nozzle is communicated with multiple second cavity volume by the second oil circuit.

As preferably, the connected mode of described fairlead and the opening part of cell body is for being threaded or welding.

As preferably, described first oil nozzle and the second oil nozzle are by the external hydraulic pump of oil pipe.

The beneficial effects of the utility model are:

1, do not need to use the dangerous material such as gunpowder, construction risk can not be caused because operation is excessive.

2, adopt hydraulic way to apply active force to rock, mechanism is comparatively light and slow, there will not be violence blasting broken stone disorderly to fly phenomenon.

3, arranging of fairlead can the scope of activities of effective limited piston, can also ensure the direction of motion of piston, realize the directional cutting to rock thus except the telescopic movable interval of limited piston

4, fairlead is threaded with the opening part of cell body, for convenience detach, maintenance.

5, the first oil nozzle and the second oil nozzle can carry out two-way delivering oil, and during the first oil nozzle input, the second oil nozzle exports, and during the second oil nozzle input, the second oil nozzle exports, and so ensure that the flexible controlled of piston.

6, the utility model can more than one piece device co-operation, realizes cutting of fixed quantity as required.

Detailed description of the invention

Below in conjunction with exemplary embodiment, embodiment of the present utility model is described:

The utility model provides one to split rock device, as shown in Fig. 1 Fig. 2, comprises cylindrical body 1, multiple piston 2, first oil nozzle 4; Cylindrical body 1 is provided with multiple cell body, and piston 2 is arranged in cell body, and the piston top of piston 2 and the inwall of cell body are slidably matched, and with cell body bottom form the first cavity volume; The bottom of cell body is communicated with for the first oil nozzle 4 to delivering oil in the first cavity volume by the first oil circuit 6.The opening part of the cell body that cylindrical body 1 is arranged also is provided with the fairlead 3 for limiting piston 2 scope of activities, and fairlead 3 is placed on the piston head of described piston 2, and forms the second cavity volume with the piston top of piston 2.The second oil nozzle 5, second oil nozzle 5 cylindrical body 1 being also provided with delivering oil in the second cavity volume is communicated with multiple second cavity volume by the second oil circuit 7.The connected mode of fairlead 3 and the opening part of cell body is for being threaded.First oil nozzle 4 and the second oil nozzle 5 are by the external hydraulic pump of oil pipe.

Operating process as shown in Figure 4, in use, operating personnel first utilize drilling machine to punch on foundation stone, then will split in rock device load hole, open the first oil nozzle connect the first hydraulic pump, by the first oil circuit to delivering oil in the first cavity volume, foundation stone squeezes by piston under the effect of the first hydraulic pump.After squeezing foundation stone, first hydraulic pump quits work, the second hydraulic pump that second oil nozzle connects is started working, by the second oil circuit to delivering oil in the second cavity volume, promote piston retraction, and the fluid in the first cavity volume is squeezed back the first hydraulic pump, operating personnel can take out smoothly splits rock device.In actual applications, often use and multiplely split rock device co-operation, split rock Be very effective.

The part do not set forth in manual is prior art or common practise.The present embodiment only for illustration of this utility model, and is not used in restriction scope of the present utility model, and the amendment such as the equivalent replacement that those skilled in the art make for the utility model is all thought to fall in this utility model right claim institute protection domain.
