Description
Technical field
The present invention relates to be applied to a kind of rapping formula pin pulling out device that mine hydraulic bracket and main equipment alignment pin are extracted, use this device easily bearing pin to be extracted.
Background technology
The coal-face hydraulic support relies on highly pressurised liquid, column and corresponding power jack to realize crane, pushing and sliding and move four elemental motions of frame, and the connection of each moving-member adopts bearing pin to connect more.Because large hydraulic support volume weight is bigger, can't go into the well on the whole, therefore must go into the well on the split ability.So just relate to the various connecting link pin work on the dismounting hydraulic support, some bearing pins are bigger, and remove relatively effort through long-term use.Cause the maintenance work task of support to increase the weight of thus, this has brought very big labour intensity certainly will for the maintenance work of hydraulic pressure support and maintenance, and operating safety factor is not high yet.
Summary of the invention
The purpose of this invention is to provide a kind of convenient and reliable rapping formula pin pulling out device.
The objective of the invention is to realize through following technical scheme:
Rapping formula pin pulling out device of the present invention comprises rapping apparatus, vibrating rod, cylinder body, piston rod, separation pad, connecting axle, positioning sleeve, adjustment packing ring and connecting bolt; Rapping apparatus is located at the vibrating rod top, and vibrating rod is connected with positioning sleeve through connecting axle, and positioning sleeve contacts with pin roll end face; The periodicity rapping power of rapping apparatus is pressed on pin roll end face with positioning sleeve; Piston rod hollow design, vibrating rod are located in the piston rod, and piston rod connects bearing pin through connecting bolt; The end face of piston rod and the spacing of bearing pin are through the adjustment of adjustment packing ring, and rapping formula pin pulling out device is installed on the support fixation seat and with Hydraulic Station and is connected.
Technical scheme by the invention described above provides can be found out; Rapping formula pin pulling out device of the present invention 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.
Description of drawings
Fig. 1 is a rapping formula pin pulling out device structural representation;
Fig. 2 is piston rod, connecting axle, positioning sleeve, connecting bolt assembling sketch map;
Fig. 3 is the piston rod construction sketch map;
Fig. 4 is connected sketch map for rapping formula pin pulling out device with supporting holder, Hydraulic Station.
The specific embodiment
Rapping formula pin pulling out device of the present invention; 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.
Rapping formula pin pulling out device of the present invention is mainly used a kind of device that mine hydraulic bracket and main equipment alignment pin are extracted, and it has following inventive 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.
Below in conjunction with accompanying drawing operation principle of the present invention is further specified:
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 invention has the beneficial effects as follows:
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 present invention, but protection scope of the present invention is not limited thereto, any technical staff who is familiar with the present technique field is in the technical scope that the present invention discloses; The variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.
