Description
Technical field
The present invention relates to the installation of hydraulic breaking hammer critical component, especially the rapid installation device of hydraulic crushing hammar drill rod seat assembly drill rod bush of drill rod and installation method.
Background technology
Drill steel seat assembly in the hydraulic breaking hammer circulating on present stage market, mainly comprises drill steel seat, drill steel, drill steel front lining, drill steel back bush, limiting bush; The cylindrical of drill steel front lining, drill steel back bush, limiting bush and the endoporus of drill steel seat are to pack into by matched in clearance, conventional design fit clearance amount is: φ is below 140+and 0.012 ~+0.069, φ is more than 160+and 0.014 ~+0.081, due to machining accuracy reason, the gap value working control of making is in+0.05 left and right.
Gap value exists more greatly following problem: one, lining is put into drill steel seat by manually beaing when mounted, easily causes scratch between lining and drill steel seat; Two, when the reversal valve of hydraulic breaking hammer carries out commutation work, the hydraulic energy transfer of 2-5 kilojoules is that mechanical energy passes to drill steel and does work to external world, outer bound pair drill steel has also produced a strong large reaction force such as approximate grade, commutation makes drill steel be subject to back and forth serious impact and vibrations frequently, produce on the one hand a large amount of energy losses, drill steel and lining heavy wear on the other hand, has shortened product service life; Have again, when drill steel is impacted by complicated alternating force, due to the existence in larger gap, drill steel is rocked in lining, cause drill steel crooked, make the core component piston rod of main frame pull cylinder body, cause occurring serious quality accident.
Summary of the invention
The problem of mentioning in order to solve background technology, condition of work based on drill steel seat and the matching relationship between kinematic pair, again provide the fit tolerance of the critical size of drill steel seat assembly, make to there is the rational magnitude of interference between drill steel seat endoporus and drill rod bush of drill rod cylindrical, design load is-0.01 ~-0.04, thereby reduces or eliminates play and the frictional resistance of kinematic pair, has improved the matching requirements of lining and drill steel, make its motion steadily, reliably, energy transfer efficiency improves.But the in the situation that of interference fit, artificial being difficult to packs lining in drill steel seat into, therefore the invention provides rapid installation device and the installation method of hydraulic crushing hammar drill rod seat assembly drill rod bush of drill rod.
For realizing above-mentioned technical purpose, the invention provides the rapid installation device of hydraulic crushing hammar drill rod seat assembly drill rod bush of drill rod, comprise crossbeam, left column, gland, the cylinder seat of high-voltage oil cylinder, piston, depression bar, right column, high pressure oil-feed loop, low pressure oil return circuit, Hydraulic Station, left and right pillar and Hydraulic Station are fixedly installed on basal plane, between left and right pillar and crossbeam, by securing member, connect into frame integral body, the cylinder seat of high-voltage oil cylinder be fixedly installed on crossbeam under, its inner piston crown is connected with depression bar, the cylinder seat of high-voltage oil cylinder is connected with Hydraulic Station by high pressure oil-feed loop and low pressure oil return circuit, gland is arranged on the drill steel seat of required assembling.
The present invention also provides the installation method of hydraulic crushing hammar drill rod seat assembly drill rod bush of drill rod, and its concrete operation step is:
The first step: be placed on backing plate drill steel seat is vertical;
Second step: limiting bush is put into the aperture (cylindrical of limiting bush is contacted with the endoporus of drill steel seat, and both axial lines coinciding) of drill steel seat upper end, the end face at limiting bush macropore place upward;
The 3rd step: install gland, adjust the position of drill steel seat, guarantee that gland is under high-voltage oil cylinder;
The 4th step: start rapid installation device, the piston of high-voltage oil cylinder is stretched by depression bar and promoted gland downwards, and limiting bush is slowly pressed into II place, position correct in drill steel seat hole, then the piston return of high-voltage oil cylinder;
The 5th step: in like manner, then pack drill steel back bush into drill steel seat, it is pressed on the upper surface of limiting bush, finally packs drill steel front lining into the correspondence position I place in drill steel seat.
In the process of mounting limit lining, drill steel back bush and drill steel front lining, drill steel seat, because the deformation that is squeezed produces larger tension force, is firmly held the lining having packed into tightly.Therefore, in the course of work of drill steel, no matter how drill steel is impacted, can not cause drill rod bush of drill rod in drill steel seat the inside play back and forth, so just reduce energy loss and the destruction to drill steel, also avoided security incident, also saved job costs.
By rapid installation device and the installation method of hydraulic crushing hammar drill rod seat assembly drill rod bush of drill rod of the present invention, drill steel seat assembly key position size is optimized to design, thereby improve matching requirements, reduce quality accident, can also realize the Fast Installation of drill rod bush of drill rod and drill steel seat, improve efficiency of assembling, guaranteed assembly quality.
