Abstract
The utility model discloses a rapid installing device of a drill rod lining of a drill rod seat assembly of a hydraulic hammer. The rapid installing device comprises a cross beam, a left stand column, a pressing sleeve, a cylinder seat of a hydraulic oil cylinder, a piston, a press rod, a right stand column, a high-pressure oil feeding loop, a low-pressure oil returning loop and a hydraulic station; the left stand column, the right stand column and the hydraulic station are fixedly arranged on a base face; the left stand column, the right stand column and the cross beam are connected together via fastening pieces, so a rack whole is formed; the cylinder seat of the high-pressure oil cylinder is fixedly arranged right under the cross beam; the head of the piston in the cylinder seat is connected with the press rod; and the cylinder seat of the high-pressure oil cylinder is communicated with the hydraulic station via the high-pressure oil feeding loop and the low-pressure oil returning loop. According to the utility model, it can be achieved that the drill rod lining is quickly installed on a drill rod seat; assembly efficiency is increased; and assembly quality is ensured.
Description
Technical field
The utility model 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.
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, in the time that 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 bending, 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, matching relationship between condition of work and kinematic pair based on drill steel seat, 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, and therefore the utility model provides the rapid installation device of hydraulic crushing hammar drill rod seat assembly drill rod bush of drill rod.
For realizing above-mentioned technical purpose, the rapid installation device of the utility model 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, connect into frame entirety by securing member, 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.
Like this in the time of mounting bush, first be placed on backing plate vertical drill steel seat, then lining put into the aperture of drill steel seat upper end, starting drive, the piston of high-voltage oil cylinder is stretched by depression bar and is promoted gland downwards, and lining is slowly pressed into correct position in drill steel seat hole.
The rapid installation device of the utility model hydraulic crushing hammar drill rod seat assembly drill rod bush of drill rod can be realized the Fast Installation of drill rod bush of drill rod and drill steel seat, has improved efficiency of assembling, has ensured assembly quality.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model hydraulic crushing hammar drill rod seat assembly drill rod bush of drill rod rapid installation device.
Detailed description of the invention
As shown in Figure 1, the rapid installation device of the utility model hydraulic crushing hammar drill rod seat assembly drill rod bush of drill rod, comprise crossbeam 1, left column 3, gland 4, the cylinder seat 6 of high-voltage oil cylinder, piston 7, depression bar 8, right column 9, high pressure oil-feed loop 10, low pressure oil return circuit 11, Hydraulic Station 12, left and right pillar 3, 9 and Hydraulic Station 12 be fixedly installed on basal plane, left and right pillar 3, 9 and crossbeam 1 between connect into frame entirety by securing member, the cylinder seat 6 of high-voltage oil cylinder be fixedly installed on crossbeam 1 under, its inner piston 7 heads are connected with depression bar 8, the cylinder seat 6 of high-voltage oil cylinder is connected with Hydraulic Station 12 by high pressure oil-feed loop 10 and low pressure oil return circuit 11, gland 4 is arranged on the drill steel seat 2 of required assembling.Wherein, high-voltage oil cylinder is realized its oil-feed and oil return by high pressure oil-feed loop and low pressure oil return line, and piston pumps by reversal valve.
This novel quick-installation device also comprises backing plate 5, and backing plate 5 is arranged on the bottom of the drill steel seat 2 of required assembling, avoids drill steel seat 2 in the time of assembling drill rod bush of drill rod directly to contact with basal plane.Meanwhile, can realize the assembling of the drill steel seat pad cover to different size and requirement by adjusting the height of backing plate 5.
By the rapid installation device of this Novel hydraulic crushing hammer drill steel seat assembly drill rod bush of drill rod, replace artificial installation, realize the Fast Installation of drill rod bush of drill rod and drill steel seat, improve efficiency of assembling; Meanwhile, rapid installation device can ensure that the axial line of lining and drill steel seat coincides, and can not cause scratch between lining and drill steel seat, thereby ensure assembly quality.The drill steel seat assembly being obtained by the rapid installation device of hydraulic crushing hammar drill rod seat assembly drill rod bush of drill rod of the present invention, play and the frictional resistance of kinematic pair are reduced or have eliminated, improve the matching requirements of lining and drill steel, make its motion steadily, reliably, improve energy transfer efficiency, saved cost.
