Technical scheme by above-mentioned the utility model provides can be found out; The described rapping formula of the utility model pin pulling out device is rational in infrastructure, easy to use, safe and reliable; Can realize automatic tension, the function that tightening force is big; Solved that the artificial hammering of original workman is bothersome, time-consuming, effort, unsafe problem, reduced post workman's workload, reduced investment.
The specific embodiment
The rapping formula pin pulling out device of the utility model; The specific embodiment that it is preferable such as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4; Rapping formula pin pulling out device comprises rapping apparatus 1, vibrating rod 2, cylinder body 3, piston rod 4, separation pad 5, connecting axle 6, positioning sleeve 7, adjustment packing ring 8 and connecting bolt 9.
Rapping apparatus 1 provides periodic rapping power.
Vibrating rod 2 is connected with positioning sleeve 7 through connecting axle 6, and positioning sleeve 7 contacts with pin roll end face, and the periodicity rapping power of rapping apparatus is pressed on positioning sleeve on the pin roll end face.
Piston rod 4 hollow design, vibrating rod 2 is located in the piston rod, and piston rod 4 connects bearing pin through connecting bolt 8, and the end face of piston rod 4 and the spacing of bearing pin are through 8 adjustment of adjustment packing ring.
Rapping formula pin pulling out device is installed on the support fixation seat 12, and rapping formula pin pulling out device is connected with Hydraulic Station 13.
The rapping formula pin pulling out device of the utility model is mainly used a kind of device that mine hydraulic bracket and main equipment alignment pin are extracted, and it has following innovative point:
The piston rod of rapping formula pin pulling out device adopts hollow design, vibrating rod and piston rod concentric fits.
Rapping formula pin pulling out device vibrating rod combines with positioning sleeve, makes the bearing pin axial float in the rapping process, prevents that axle is stuck.
Rapping formula pin pulling out device and equipment gap location add separation pad, have strengthened the effective travel of pin pulling out device.
Rapping formula pin pulling out device adopts rapping and hydraulic pressure to pull pin and combines, and the process of pulling pin is steady.
Further specify below in conjunction with the operation principle of accompanying drawing the utility model:
When rapping formula pin pulling out device uses; Earlier with rapping formula pin pulling out device its centre-height of position adjustment according to the equipment bearing pin of dismantling; Hydraulic Station gets into oil cylinder at hydraulic control system effect downforce oil from hydraulic fluid port 10; Effect lower piston rod 4 at control oil stretches out, and reaches range and stops, and then the piston rod top is linked up through connecting bolt 9 and bearing pin; The top of piston rod and the distance of bearing pin can be adjusted through adjustment packing ring 8, guarantee piston rod 4 during in range positioning sleeve 7 contact with pin roll end face, rapping apparatus 1 is positioned over the top of vibrating rod; Energized, under rapping apparatus 1 periodicity active force effect, bearing pin and institute's connection device produce axial float; Remove rapping apparatus 1 then, Hydraulic Station gets into oil cylinder at hydraulic control system effect downforce oil from hydraulic fluid port 11, in effect lower piston rod 4 contractions of control oil; Under the effect of connecting bolt 9, bearing pin moves with bolt, if the stroke of piston rod is not enough; Can between rapping formula pin pulling out device and equipment, install separation pad 5 additional, increase the effective travel of rapping formula pin pulling out device, can bearing pin be extracted; Then bearing pin is removed, this moment, the whole process of pulling pin was accomplished.
The beneficial effect of the utility model is:
Rational in infrastructure, easy to use, safe and reliable, can realize automatic tension, the function that tightening force is big.
Solved that the artificial hammering of original workman is bothersome, time-consuming, effort, unsafe problem.
Reduce post workman's workload, reduced investment.
The equipment simple installation, easy to operate.
The above; Be merely the preferable specific embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technical staff who is familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.
