Abstract

The utility model provides a seam device is made in rock drilling constitutes by making seam hammer, hinge, expanding stopper, adduction stopper, pipe, rectangular hole, expansion jump bit outward. Seam device is made in rock drilling fixed mounting is on the electric hammer, and the electric hammer drill changes the expansion jump bit into can. The device is a stress concentration phenomenon of utilizing brittle material, and the people makes expansionary force focus on drilling and makes the seam position for making the seam, and the rock divides more easily, uses same division power can reduce drilling quantity, and the equipment of less power can be used to same drilling quantity. The the device design is ingenious, simple structure, and convenient operation can improve work efficiency effectively, reduces the operating cost.

Description

Seam device is made in rock-boring

Technical field

This utility model belongs to field of civil engineering, and seam device is made in specifically a kind of rock-boring.

Background technology

In civil engineering construction, it usually needs dismantling concrete, the broken cubic meter of stone, cutting stone material, carry out tunnel, culvert work Journey explosion, the Mechanical Crushing method of routine, such as pneumatic pick, Hydraulic pick, quartering hammer etc., are to act on destroying object by external impacts Structure.The comprcssive strength as concrete, rock being broken is very high, and tensile strength only has the 10% of its comprcssive strength;Work Journey technical staff utilizes this low characteristic of tensile strength of fragile material, completes above-mentioned work using rock splitter;First, exist The hole of one row's special diameter and depth is bored on the rock being split off, the voussoir group of splitter is inserted in the hole, using dynamic impact problem Driving the center chock in splitter voussoir group to roll away from forward, reverse voussoir being strutted to both sides, thus producing huge division Power, by the object structures being split off internal sabotage and divide and come;It is frequently necessary to even thousands of using producing hundreds of ton in engineering The splitter of the huge thrust of ton, promotes contract piece to expand to both sides;Inefficiency, high cost, speed of application is slow.

Utility model content

In order to solve above-mentioned technical problem present in prior art, this utility model provides a kind of rock-boring and makes seam Device, by make seam hammer, hinge, extend out limited block, interior receipts limited block, conduit, rectangular opening, extension shock hammer form, described The dynamic impact problem that seam device use is made in rock-boring is identical with electric hammer, and this device is fixedly mounted on electric hammer, and electric hammer drill changes into Extension shock is hammered into shape;Make seam hammer about two be symmetrical arranged, lower end is hinged by hinge, arranges at an acute angle, in the two outside upper end When holding together, slightly larger than bore diameter, ensuring equipment is stuck in boring outer distance always.

Further, the described limited block that extends out is fixedly installed on conduit bottom, and conduit diameter is less than bore diameter;Interior receipts limits Position block is fixedly installed on makes seam hammer bottom, ensures that rock-boring is made seam device and can not be slipped in boring;

Rectangular opening is opened up above conduit.

According to Elasticity knowledge, in body form place jumpy, at wedge angle, breach, groove, stress occurs Concentration phenomenon.Stress concentration can make fragile material produce fatigue crack, once producing, through crack moment is formed localized crackses. This characteristic that seam device exactly utilizes fragile material is made in rock-boring, artificially makes seam, makes expansionary force focus on boring and makes seam position Put, rock easily divides;Same division tension force can reduce drilling hole amount, and same drilling hole amount can use smaller power Equipment.This device is skillfully constructed, and structure is simple, easy to operate, can effectively improve work efficiency, reduces operating cost.

Specific embodiment

The utility model is described in further detail below in conjunction with the accompanying drawings.

As shown in figs. 1-7, rock-boring of the present utility model make seam device by make seam hammer 1, hinge 2, extend out limited block 3rd, interior receipts limited block 4, conduit 5, rectangular opening 51, extension shock hammer 6 composition;The impact that seam device uses is made in described rock-boring Power is identical with electric hammer, and this device is fixedly mounted on electric hammer, and electric hammer drill changes extension shock hammer 6 into;Make seam hammer 1 about two Individual be symmetrical arranged, lower end is hinged by hinge 2, arranges at an acute angle outside upper end, and when holding together in the two, outer distance is straight slightly larger than boring Footpath, ensuring equipment is stuck in boring always.

The described limited block 3 that extends out is fixedly installed on conduit 5 bottom, and conduit 5 diameter is less than bore diameter;Interior receipts are spacing Block 4 is fixedly installed on makes seam hammer 1 bottom, ensures that rock-boring is made seam device and can not be slipped in boring;

Conduit 5 opens up rectangular opening 51 above.

When seam device use is made in rock-boring of the present utility model, make about electric hammer, to make what seam hammer needed parallel to rock Divisural line, puts into boring catheter proximal end, makes seam hammer and is stuck in the upper edge of boring, turns on the power, extension shock hammers undershoot into shape, impact is made Seam hammer, makes seam hammer and extends out chisel and cut boring side rock；Extension shock hammer is up, and conduit is descending under electric hammer Gravitative Loads, compels Make to make in seam hammer.Extension shock is hammered into shape up and down reciprocatingly, and boring radially opposite sides dig into two vertical slits.Then proper splitting rock Stone.
