Abstract
A kind of hydraulic swelling method and device thereof that is applicable to work stones such as quarry marble, granite, expander is placed in the round of preboring, with high-voltage tube expander is connected with hydraulic power unit, the high pressure that produces by hydraulic power unit makes expander produce expansion force, makes the rock spalling.The present invention is simple in structure, and is easy to operate, and power is little, can adopt manual, electronic or diesel engine drives, and in quarrying stone, alleviates labor strength greatly, raises labour productivity and operational security.In addition, this device does not have leakage, and use in the area that is specially adapted to lack of water.
Description
The present invention relates to a kind of breaking method and device thereof of rock, more specifically say so a kind of hydraulic swelling method and device thereof.
At present, the nothing of known quarry marble, granite and coal mine roadway is shaken several modes below main employing the such as driving:
(1) with artificial wedge quarry marble, granite etc.On rock, bore good orifice part and load onto bquster, knock with hammer then.This exploitation method labor strength is big, and production efficiency is low, and strength is little, need sometimes by gunpowder explosion operation simultaneously, and power only acts on orifice part, and lumber recovery is low.
(2) exploit by the hydraulic pressure splitting machine.Its broken rock principle is the same with artificial wedge, at first the wedge head part of hydraulic pressure splitting machine is inserted on the aperture of rock, start oil pump then, the hydraulic cylinder that drives on the hydraulic pressure splitting machine comes to the wedge head application of force, this rock breaking method also exists following problem, and the wedge head acts on power on the rock only at orifice part, and lumber recovery is low, and this machine price is expensive, and the life-span is short.
(3) exploit with the Static crushing agent, the Static crushing agent that will be furnished with water is packed in the pre-drilled rock pore, and with cement or stemming the hole is sealed, along with water and cracking agent react and produce expansion, by expanding the rock spalling.The shortcoming of the broken rock of this method is: the usage charges height, long action time, the holding breaking agent process is slow, and the time have the hurt sb.'s feelings accident of face of cracking agent ejection to take place, the cracking agent keeping also requires strict.
(4) utilize water under high pressure to break rock:
19 pages of " high-pressure water jet " sponsored by Jiangsu Inst. of Coal Mine 1988 the 1st phases have been introduced a kind of " water under high pressure breaks rock ", adopt high-pressure hydraulic pump, swivel coupling, turning motor and hole sealing device etc., hole sealing device is contained in the rock pore oral area, seal the water under high pressure that injects petrosal foramen, thereby water under high pressure is constantly raise, and utilization makes catalase with the water under high pressure that rock pore directly contacts.
Japan Patent: clear 60-203798, name is called: the breaking method of rock and device thereof, it is to utilize hammer drill to get out a hole in advance, adds hole packer in the aperture again, utilizes water under high pressure and the drill bit rock of coming together brokenly.
The deficiency of the broken rock of above-mentioned two kinds of water under high pressures is: the equipment manufacturing cost costliness, and heaviness and power are big, the hole packer troublesome poeration, and be difficult for sealing, hole packer is short application life, and location, the plateau olighydria that has, and this equipment just is difficult for using.In addition,, original crack is arranged, just more be difficult for sealing as rock because of water under high pressure directly contacts with rock, and the growth of easier initiation original crack, and making rock not along the direction cracking of needs, lumber recovery is low.
The objective of the invention is to have designed hydraulic swelling method and the device thereof that a kind of power is little, in light weight, active force is big, lumber recovery is high in order to overcome above-mentioned the deficiencies in the prior art part.
Purpose of the present invention can realize in the following manner:
A kind of hydraulic swelling device mainly is made up of hydraulic power unit, high-voltage tube and expander, expander is placed in the pre-drilled round of rock mass, with high-voltage tube expander and hydraulic power unit are communicated with, the high pressure that utilizes hydraulic power unit to get makes expander produce expansion force, makes the rock spalling thereby produce enormous function power.
A kind of hydraulic swelling method is placed in expander in the round of rock mass, and the high pressure that utilizes hydraulic power unit to get expands expander, acts on the rock mass thereby produce huge expansion force, makes the rock spalling.
The present invention has following advantage:
(1) adopted expander, do not had and leak, required hydraulic flow is little, and the contact area of expander and rock pore is bigger, and required pressure is not high yet, generally at 30MP
aAbout.Required power is little, and the time spent is done in tens holes simultaneously, only needs a manual pump just enough.
(2) the expander active force is big.Action time is fast, and is just inflatable in a few minutes, both alleviated working strength of workers, improved productivity ratio again.
(3) weight of equipment is light, has only tens kilograms, very easy on-the-spot use the, easily carrying in the mine.
(4) easy and simple to handle, as long as expander is put into the hole, open hydraulic power unit and get final product, and safe and reliable.
(5) lumber recovery height can be controlled the rock crack direction, is difficult for causing in rock mass crackle.
(6) this device long service life, each expander can be with more than 2000 times.
Description of drawings:
Accompanying drawing 1 is work structuring figure of the present invention.
Accompanying drawing 2 is structural representations of expander of the present invention.
The invention will be further described with reference to the accompanying drawings:
Shown in accompanying drawing 1: Fig. 1 has showed work system figure of the present invention.Mainly comprise by hydraulic power unit 1, high-voltage tube 2 and expander 3 and forming.Drivings such as artificial, the electronic or diesel engine of said hydraulic power unit 1 optional usefulness are placed in expander 3 in the round of preboring, with high-voltage tube 2 expander 3 are connected with hydraulic power unit 1, and expander 3 produces expansion under hydraulic action.Act on the petrosal foramen wall thereby produce huge expansion force, make the rock spalling.Can exploit out required big lumpiness work stone according to the boring of quarrying needs.
Shown in accompanying drawing 2: Fig. 2 has showed the structure of expander 3.Expander 3 mainly is made up of expansion tube 4, joint core 5, fitting sleeve 6, vent cover 7.The sebific duct of winding steel wire in expansion tube 4 is selected for use, its two ends are all withheld the top connection heart 5 and fitting sleeve 6, the one ends vent cover 7 of also screwing on.When in the expander 3 air being arranged, can unscrew vent cover 7 and air is released, the other end links to each other with hydraulic power unit by high-voltage tube.
During use, earlier expander 3 is placed in the round of preboring, closes the switch valve on the hydraulic power unit 1, open pump.Give expander 3 by high-voltage tube 2 with hydraulic pressure transfer, the fluid pressure in the expander 3 constantly raises, and makes expander 3 produce the diametric plane expansion force, and acts on the hole wall, and when pressure reached certain value, rock can be along the round aspect by spalling.Open switch valve, the liquid in the expander 3 is got back in the hydraulic fluid tank under the elastic reaction of expansion tube 4, just can take out each expander 3, reinstalls use.
