Description
Technical field
The utility model belongs to plant equipment manufacturing technology field, relates in particular to a kind of rock drill.
Background technology
Hammer drill be a kind of on rock the machine in Drilling hole, its groundwork principle is with calming the anger as power, by passive valve control piston, move back and forth, piston impact drilling tool cutter crushed rocks during stroke, during backhaul, piston driving drilling tool turns round certain angle, and continuous impact, revolution make drilling tool on rock, dig out circular big gun hole.At present, at engineering fields such as coal, mining industry, be widely used hammer drill, utilize this equipment to carry out bore operation to different rock mass, for follow-up explosive, install and lay the first stone, the service behaviour of equipment is directly connected to the position that later stage explosive is installed, and directly affects secondary explosion effect.
Existing hammer drill lacks a horizontal plane, so affect the adjustment direction of drill steel while tunneling, cannot be close to country rock and become horizontal drilling depth.Therefore between each boring circulation, there are a large amount of faulting of slab ends, increased construction cost, strengthened construction safety risk.Only having the hammer drill of working as to be close to country rock becomes horizon to push ahead; a upper cyclic advance just can become horizon to extend with next cyclic advance; operating personnel strictly control when jewel hole; make jewel hole achievement reach highest standard; vault and both sides country rock after driving cavitation reach smooth, reduce concrete work amount, could reduce preliminary bracing cost; strengthen the protection to country rock in tunnel excavating process, reduce every drilling depth circulation faulting of slab ends excessive and the potential safety hazard brought and the waste of material.
Summary of the invention
The purpose of this utility model is to provide a kind of rock drill, thereby solves the problem in above-mentioned background technology.
The utility model content is achieved through the following technical solutions:
A kind of rock drill, comprise bit shank sleeve, turning set, head, spline is female, lining, fairlead, piston, rifle bar, rifle nut, valve, cylinder body, ratchet, handle, long bolt, nut, described cylinder body upper end is connected with respectively handle and head through long bolt and nut, on the left end inwall of described cylinder body, be provided with fairlead, on described fairlead inwall, be provided with lining, in described cylinder body, be provided with piston, on the right-hand member inwall of described piston, be provided with rifle nut, in described rifle nut, be connected with the rifle bar of horizontally set, the upper right side of described rifle bar is connected with ratchet, described ratchet connects cylinder body and handle, the middle upper end of described rifle bar is provided with the valve that is positioned at cylinder body, on described head inwall, be provided with turning set, on described turning set left end inwall, be provided with bit shank sleeve, on described turning set right-hand member inwall, be provided with spline mother.
As a kind of improvement, described cylinder body below is provided with sound proof housing.
As a kind of improvement, the horizontal rise that described cylinder body and head form is controlled at 1.8cm-2cm.
The utlity model has following beneficial effect:
Sound proof housing of the present utility model is arranged on inferior part of the cylinder block, the horizontal rise that cylinder body and head form is controlled at 1.8cm-2cm, during boring, rock drilling function is close to the upper surface operation of big gun hole as much as possible, reduced to greatest extent the gradient error producing in rock drilling progradation, operating personnel have clear and definite sense of direction, only need be close to the propelling of country rock surface by the upper plane of hammer drill and just reach its optimum efficiency, expand job area.This hammer drill is owing to there being a horizontal plane, in work progress, rig being close to country rock advances, increased the adjusting range of controlling excavation, improve in digging process backbreaking, effective control of owing to dig, the impact of reduction on country rock slackness, the precision of jewel hole directly affects the precision of excavated section, the precision of jewel hole controlled well is key one ring of current mountain tunnel drill bursting construction, controlling out break and reducing faulting of slab ends is the core of construction of explosion, therefore use this hammer drill in conjunction with smooth blasting method, can greatly improve efficiency of construction, reduce constructing tunnel support cost, strengthen construction safety guarantee.The utility model device structure is simple, and operating efficiency is high, and work quality is good, and safeguard convenient, long service life.
