Description
Technical field
The present invention relates to be applied to a kind of vibration type pin pulling device that mine hydraulic bracket and main equipment alignment pin are extracted, use this device easily bearing pin to be extracted.
Background technology
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 larger, cannot go into the well on the whole, therefore must in split ability, go into the well.So just relate to the various connecting link pin work on dismounting hydraulic support, some bearing pins are larger, and remove relatively effort through long-term use.Cause thus the maintenance work task of support to increase the weight of, this certainly will bring very large labour intensity to maintenance work and the maintenance of hydraulic support, and operating safety factor is not high yet.
Summary of the invention
The object of this invention is to provide a kind of convenient and reliable vibration type pin pulling device.
The object of the invention is to be achieved through the following technical solutions:
Vibration type pin pulling 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 vibrating rod top, vibrating rod is connected with positioning sleeve by connecting axle, positioning sleeve contacts with pin roll end face, the periodicity rapping power of rapping apparatus is pressed on pin roll end face by positioning sleeve, piston rod hollow design, vibrating rod is located in piston rod, and piston rod connects bearing pin by connecting bolt, the end face of piston rod and the spacing of bearing pin are adjusted by adjusting packing ring, and vibration type pin pulling device is installed on and supports on holder and be connected with Hydraulic Station.
As seen from the above technical solution provided by the invention, vibration type pin pulling device of the present invention is rational in infrastructure, easy to use, safe and reliable, can realize automatic tension, function that tightening force is large, solved that the artificial hammering of original workman is bothersome, time-consuming, effort, unsafe problem, reduced post workman's workload, reduced investment.

Fig. 2 is piston rod, connecting axle, positioning sleeve, connecting bolt assembling schematic diagram;
Fig. 3 is piston rod construction schematic diagram;
Fig. 4 is vibration type pin pulling device and supporting holder, Hydraulic Station connection diagram.
The specific embodiment
Vibration type pin pulling device of the present invention, preferably the specific embodiment is as shown in Figure 1, Figure 2, Figure 3, Figure 4 for it, vibration type pin pulling device, comprises rapping apparatus 1, vibrating rod 2, cylinder body 3, piston rod 4, separation pad 5, connecting axle 6, positioning sleeve 7, adjusts packing ring 8 and connecting bolt 9.
Rapping apparatus 1 provides periodic rapping power.
Vibrating rod 2 is connected with positioning sleeve 7 by 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 pin roll end face.
Piston rod 4 hollow design, vibrating rod 2 is located in piston rod, and piston rod 4 connects bearing pin by connecting bolt 8, and the end face of piston rod 4 and the spacing of bearing pin are adjusted by adjusting packing ring 8.
Vibration type pin pulling device is installed on and supports on holder 12, and vibration type pin pulling device is connected with Hydraulic Station 13.
Vibration type pin pulling device of the present invention, mainly applies 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 vibration type pin pulling device adopts hollow design, vibrating rod and piston rod concentric fits.
Vibration type pin pulling device vibrating rod is combined with positioning sleeve, makes bearing pin axial float in rapping process, prevents that axle is stuck.
Vibration type pin pulling device and equipment gap location add separation pad, have strengthened the effective travel of pin pulling out device.
Vibration type pin pulling 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 illustrated:
When vibration type pin pulling device is used, first vibration type pin pulling device is adjusted to its centre-height according to the position of institute's detaching equipment bearing pin, Hydraulic Station enters oil cylinder at hydraulic control system effect downforce oil from hydraulic fluid port 10, at the oily effect lower piston rod 4 of control, stretch out, reach range and stop, then piston rod top being linked up by connecting bolt 9 and bearing pin, the top of piston rod and the distance of bearing pin can be adjusted by adjusting 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 to the top of vibrating rod, switch on power, under rapping apparatus 1 periodicity active force effect, bearing pin and connected device produce axial float, then remove rapping apparatus 1, Hydraulic Station enters oil cylinder at hydraulic control system effect downforce oil from hydraulic fluid port 11, controlling 4 contractions of oily effect lower piston rod, under the effect of connecting bolt 9, bearing pin moves with bolt, if the stroke of piston rod is inadequate, can between vibration type pin pulling device and equipment, install separation pad 5 additional, increase the effective travel of vibration type pin pulling device, bearing pin can be extracted, then bearing pin is removed, now the whole process of pulling pin completes.
The invention has the beneficial effects as follows:
Rational in infrastructure, easy to use, safe and reliable, can realize automatic tension, function that tightening force is large.
Solved that the artificial hammering of original workman is bothersome, time-consuming, effort, unsafe problem.
The workload that has reduced post workman, has reduced investment.
Equipment simple installation, easy to operate.
The above; be only the present invention's specific embodiment preferably, but protection scope of the present invention is not limited to this, is anyly familiar with in technical scope that those skilled in the art disclose in the present invention; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.
