Description
Technical field
This practicality relates to a kind of non-explosion stone-splitter, particularly relates to a kind of splitting rod of stone-splitter.
Background technology
In traditional rock and mining, no matter be strip mining transformation or underground mining, great majority all adopt the method for drilling and blasting at present.Along with China's expanding economy, the consideration of environmental protection and constructor's safety, very strict to the control of explosion medicine, not only need the professional explosion company that please have explosion qualification to carry out bursting work.The costs such as explosion medicine also skyrocket day by day, and add examination & approval explosion formality and also bother very much, this just causes and constantly promotes with traditional blasting method cost.
At present, patent publication No. is the hydraulic dislodging machine with wedge of CN2253775Y, and hydraulic dislodging machine with wedge is by cylinder body, the elastic dilatation device of piston, piston rod, thread bush, connecting ring, splitting wedge, band slip wing plate, and fixed operating sleeve, fairlead and limited block are formed.Highly pressurised liquid in cylinder body promotes piston movement, makes piston rod simultaneously, splitting wedge moves down, by wedge stone expander separately, thus by rock cleavage.But because this hydraulic dislodging machine with wedge needs manpower to fix this hydraulic dislodging machine with wedge in operation, but move downward in the process of splitting stone comparatively large to the reaction force of people due to splitting wedge, the requirement of operating personnel's strength is larger.
Another section of patent publication No. is non-blasting mining and the driving rock splitter of CN201297173Y, the present invention is a kind of non-blasting mining and driving rock splitter, belong to mining and heading equipment, it is characterized in that in body, uniformly along its length offer vertical blind hole, piston bush is fixedly mounted in each blind hole, hypomere diameter is all offered large in each piston bush, the step through hole that epimere diameter is little, equipped band bar plug in each step through hole, between body and piston bush and piston, between piston rod and piston bush, all fluting installs ultra-high voltage sealing ring, the oil suction chamber on piston two sides and oil back chamber, by entering, drainback passage connects with peripheral hardware oil sources.Sealing described is in the publication all adopt sealing ring sealing, and piston bush is abradable seal circle in motion process, then hydraulic oil can be caused to leak from the sealing ring of piston bush.
The method of rock cleavage is realize processing the cylindrical cavity of pre-buried splitting machine by rig with drilling on the rock of splitting by existing employing non-blasting mining and driving rock splitter, hydraulic oil is supplied again in splitting rod, by the end face of piston rod, cavity curved inner wall is exerted a force, reach the effect of splitting rock.
Utility model content
The utility model is the sealing problem solving current Hydraulic Explosion breaking device.
The utility model proposes a kind of splitting rod of stone-splitter, comprise excellent shell, the radial direction of described excellent shell offers the cavity of some accommodation pistons movement, cavity is divided into oil back chamber and oil suction chamber by described piston, some described oil back chambers are communicated with by back oil road, some described oil suction chambers are communicated with by oil input channel, one end of described back oil road and described oil input channel passes excellent shell axial end, described back oil road is fixedly connected with high pressure connection respectively with the port of described oil input channel, the end of described oil back chamber is provided with end cover, the piston rod that described piston is fixedly connected with passes described end cover and protrudes from outside end cover, described some end covers are threaded with some oil back chambers.
The beneficial effects of the utility model are: the cavity offering the movement of some accommodation pistons in the radial direction of excellent shell, some cavitys that can hold piston movement, can realize in a use procedure, to dug elongated hole inwall axial many places inwall force, the central axis upright of force direction and excellent shell; Cavity is divided into oil back chamber and oil suction chamber by piston, by injection liquid force feed in oil back chamber and oil suction chamber, can promote piston and move along the central axis of piston; Some oil back chambers are communicated with by back oil road, can effectively ensure when to oil back chamber injection liquid force feed, can realize some pistons and move to oil suction chamber simultaneously; Some oil suction chambers are communicated with by oil input channel, when can effectively ensure to oil suction chamber injection liquid force feed, can realize some pistons and move to oil back chamber simultaneously; One end of back oil road and oil input channel passes excellent shell axial end, back oil road is fixedly connected with high pressure connection respectively with the port of oil input channel, high pressure connection is arranged, and the splitting rod that can realize stone-splitter is connected with the dismounting between hydraulic pump, is convenient to receive the splitting rod arranging stone-splitter; The end of oil back chamber is provided with end cover, makes oil back chamber be a space sealed; Comparatively end cap is slidably connected in oil back chamber, adopt sealing ring end cover outer wall, gap is had between end cover and oil back chamber inwall, and can move under the drive of piston due to end cap, cause the ring wear of end cap outer ring, cause sealing effectiveness poor, excesssive gap after long-time use between end cover and oil back chamber inwall, there is the leakage of hydraulic oil, but end cover is threaded with oil back chamber, be threaded between end cap and oil back chamber and there is no Relative friction, then can effectively avoid hydraulic oil from the leakage between end cover and oil back chamber contact surface.End cover is threaded with oil back chamber simultaneously and can provides the condition of a pressurize for piston moves to oil suction chamber.
Further optimization, back oil road is positioned at oil back chamber near end cover side through excellent shell, piston is provided with annular stop boss by end cover side, circular orientation block can position in end cover lateral movement piston, prevent from piston from blocking to have, ensure back oil road conducting all the time, oil suction chamber inwall is provided with limited block, avoid blocking and block back oil road in oil back chamber motion process, in oil suction chamber, wall circular is provided with limited block, and limited block can prevent piston from oil suction chamber moving process, blocking oil input channel.
Further optimization, excellent shell axial end is fixedly connected with handle, and the splitting rod of hand-held stone-splitter is convenient in the setting of handle, is arranged on excellent shell axial end simultaneously, effectively can utilizes excellent shell axial length.
Further optimization, the outer face of end cover offers bearing pin blind hole, and offering of bearing pin blind hole can be convenient to apply with piston to be that axle center torque provides stress point to end cover, realizes end cover and screws in oil back chamber port.
Further optimization, manufacture integrated with piston of piston rod forms, and can effectively avoid piston rod to be fixedly connected on piston, because external force is excessive, cause the local stress of piston rod and Piston connecting portion excessive, cause piston rod and piston breakage, affect the life-span of the splitting rod of stone-splitter.
Further optimization, there is the curved surface of fitting with the cylindrical cavity inwall of pre-buried splitting machine the end of piston rod, curved surface and cylindrical cavity are fitted, the contact area of piston rod end face is caused to increase, reduce the local stress of piston rod end face, thus reduce the local distortion of piston rod, improve the life-span of piston rod.
