The utility model has been obtained following technique effect:
The utility model impactor convenient disassembly, the efficient height just can be dismantled the impactor outer tube automatically by equipment of a people.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of top board;
Fig. 3 is the structural representation of lower platen.
The specific embodiment
A kind of down-the-hole air hammer provision for disengagement as Figure 1-3, it comprises workbench 1, workbench is provided with disconnect assembly, clamp assemblies and hydraulic system, described disconnect assembly comprises the spanner 6 that connects successively, upper bracket 8, first jack 9, undersetting 10 and base 11, base is arranged on the workbench, does not sell 7 hinged by first between spanner and the upper bracket, and undersetting does not sell 12 hinged by second between base; Described clamp assemblies comprises portal frame 2, is provided with upper holder block 3 and lower lock block 4 in the portal frame, and the lower lock block bottom is provided with second jack 5, is used for holding the outer shell that is disassembled down-the-hole air hammer between top board and the lower platen; Described hydraulic system comprises hydraulic pump 13, hydraulic hand-pump gets final product, hydraulic pump is provided with reversal valve 17, and hydraulic pump connects first jack and second jack respectively by hydraulic oil pipe 14, and the oil circuit that connects second jack is provided with Pressure gauge 15 and stop valve 16.Described top board is fixed on the portal frame upper inner, and described lower platen is in the portal frame lower inside, and lower platen can slide up and down setting along portal frame.
Workbench 1 is to be welded by steel plate, channel-section steel, angle bar, is the pedestal of whole stripping attachment, and other parts all are to be connected on the workbench; Portal frame 2 is connectors of upper holder block 3 and lower lock block 4, upper holder block is fastened on the portal frame by screw, lower lock block is upwards slided on portal frame on the top by second jack 5, upper and lower briquetting is to compress and the fixing critical piece of down-the-hole air hammer, second jack 5 provides chucking power, lock impactor, avoid the part of its rotation; Spanner 6 is not connected upper bracket 8 by selling 7, and upper bracket connects first jack, 9, the first jack 9 provides thrust, drives spanner 6 rotations.Undersetting 10 is connected by not selling 12 with base 11, is that first jack 9 provides support; Hydraulic pump 13 by hydraulic oil pipe 14, to second jack 5 and first jack, 9 delivery hydraulic pressure oil, is provided with Pressure gauge 15 in the oil circuit; Stop valve 16, its effect are to prevent 5 pressure releases of second jack; Manual pump 13 is provided with reversal valve 17, comes respectively to second jack 5 and first jack, 9 fuel feeding by the reversal valve gear.
The main implementation step of the utility model is that hydraulic pressure compresses cylinder body and the rotation of hydraulic drive joint
One, hydraulic pressure compresses cylinder body.Second jack 5 ejects lower lock block, make upper and lower briquetting and the interlock of cylinder body circumference, the concave surface of upper and lower briquetting (as Fig. 2,3) becomes circular arc type, arc surface when second jack is worked, can make the cylinder body of down-the-hole air hammer contact the square flank of tooth fully through being processed into the square dentation, and the gap of square between cog can make the post tooth tightly bite cylinder body, in order to compress, when (back) joint rotated before first jack drive spanner reaches, cylinder body did not rotate because of the rotation of preceding (back) joint.
Two, hydraulic drive joint rotation.Upper bracket connects first jack 9 and spanner 6, and upper bracket and spanner are by not being connected, and when first jack piston rod was extrapolated, the drive spanner moved, thereby forced joint to rotate.
Below for this reason the device concrete using method:
1, impactor is put into provision for disengagement the inside;
2, regulate the position of impactor and spanner, make spanner block joint square opening place and be in the same plane with first jack;
3, the manual pump reversal valve is pulled to horizontal level, slowly shaken the manual pump handle then, at this moment, clamp second jack and begin to clamp outer shell, the hydralic pressure gauge pointer begins to rotate, and when hydralic pressure gauge pointed 63Mpa, stops to shake;
4, stop valve is tightened, prevent from compressing the second jack pressure release;
5, the manual pump reversal valve is pulled to vertical position, slowly shaken the manual pump handle then, first jack 9 begins to push, and by spanner impactor is slowly dismantled;
6, after joint disassembly finishes, the manual pump reversal valve is pulled to horizontal level 9 oil returns of first jack;
7, stop valve is unclamped;
8, the manual pump reversal valve is pulled to vertical position, 5 oil returns of second jack, last lower lock block no longer compresses outer shell;
9, after joint disassembly finishes, repeat above-mentioned steps, carry out next one dismounting.
