Description

A kind of rock hydraulic splitting machine

Technical field

The present invention relates to a kind of rock hydraulic splitting machine, a kind of hydraulic splitting machine being applicable to granite and the twice decomposition of other rocks and stone mining.

Background technology

Main method explosion and quartering hammer that current domestic rock decomposes decompose.The acceleration built along with national basis, both approaches is the most greatly limited and cannot be used.It is thus desirable to a kind of efficient quarrying method meets use demand when they can not use.

Rock hydraulic splitting machine is because its volume is little, equipment simple, and conveniently moving, place to use is unrestricted;During work, static pressure slowly discharges, safe and reliable, does not has noise, does not pollutes the environment, and the decomposition rock time is short, and efficiency is high, aligns mutually after rock mining.Can be widely used for the dismounting operation of stone mining, urban tunnel construction and building.

There are some problems in domestic existing rock hydraulic splitting machine, the mounting design of such as split block is unreasonable, cause the contact surface of split block and voussoir in split block motor process to change, make the frictional force on some surface and extruding force become big, exacerbate parts depreciation and deformation;Piston rod is when voussoir power transmission, and the transmission of power is uniform not, causes voussoir to deform;Split block return when recoil movement is not accurate enough so that the preliminary preparation of broken rock becomes big, reduces production efficiency.

Summary of the invention

The technical problem to be solved is: designs the most rational machinery and hydraulic structure, makes the laminating plane of splitting machine operationally split block and voussoir to change, reduces the device damage caused because of friction and extruding;Design force transferring structure makes power transmission uniform, Reducing distortion;The effect of split block backhaul is provided with spring, makes backward position accurate.

Its technical scheme is: a kind of rock hydraulic splitting machine, including hydraulic cylinder, piston rod, sealing block, connector, split block, voussoir, spring, handle, it is characterised in that: described hydraulic cylinder is made up of hydraulic cylinder and connector;Described splitting machine load transfer device is made up of with voussoir piston rod;The sealing guider of described piston rod is made up of sealing block, piston rod guide sleeve, O RunddichtringO and ASW type dust ring;Described split block motion parts is made up of connector, voussoir, spring and split block;Described spring is installed and is made up of handle and split block;Sealing of hydraulic cylinder relies on the cooperation of hydraulic cylinder and connector to realize;Splitting machine power transmission load transfer device is rigidly connected by piston rod and voussoir and realizes;The sealing guider of described piston rod relies on piston rod guide sleeve, O RunddichtringO and ASW type dust ring to be arranged in sealing block endoporus and realize;Split block motion parts is realized by connector, split block and spring;Spring 10 is arranged on the pin of handle and split block setting.

The method have the advantages that the good seal performance of hydraulic cylinder and piston rod, oil liquid leakage reduces, dust ring is installed additional to adapt to the environment that when splitting machine works, dust is many in sealing, connector simultaneously works as sealed hydraulic cylinder body and installs the effect of split block, the rigidity of splitting machine is more preferable, piston rod and voussoir are rigidly connected, power transmission is effective, during splitting machine work, split block and voussoir binding face will not change, and part stress is uniform, and abrasion deformation is little, split block backhaul relies on spring to provide power, and return is accurate.
