Description
Technical field
The present invention relates to ore deposit hydraulic support maintenance parts, and shaft device is pulled out more particularly, to a kind of hydraulic support hinge.
Background technology
Hydraulic support is the works for controlling coal-face mine pressure, is that whether safe influence coal mining activity is
One of key factor.Therefore, need that periodically hydraulic support is overhauled and safeguarded in actual coal mining activity, so as to ensure well
The normal use in lower synthetic operation face.When hydraulic support overhauls, the first procedure for disassembling hydraulic support is exactly by structural member
The hinge of junction is extracted out of hinge hole.Traditional shaft device that pulls out is hydraulic jack, and hinge is welded or is threaded in
The outer end of piston rod, pulled by the recovery of jack piston rod and pull out axle, tensions constant.But as Design of Powered Supports is held
The increase of power is carried, hinge diameter is also increasing, and to ensure bracket stable, the gap of hinge hole and hinge is less and less；Secondly,
Subsurface environment is severe, and hinge surface corrosion is serious and the finely ground particle substance such as downhole powder dust is easily accessible in fit clearance and forms resistance
Plug, and because support uses in long-time, there is compressive deformation phenomenon in hinge.Therefore, shaft device is pulled out very using above-mentioned
Hardly possible extracts hinge.Therefore, there is mechanism to have studied a kind of detaching device for pin shaft, the provision for disengagement includes cylinder, pneumatic vibrator
And ball-screw, realization is gradually loosened by vibration shock hinge and pulls out axle；But above-mentioned provision for disengagement only provides vibration punching
Power is hit, it is necessary to which axle extraction could will repeatedly be pulled out by hitting, operating efficiency is low.
The content of the invention
Present invention aims at propose it is a kind of pull out axle is simple to operate, pull out axle smoothly and pull out shaft efficiency it is high hydraulic support hinge

Connector is fixed with knocking gear；The right-hand member of cylinder barrel is fixed with fixed seat, is offered in the fixed seat along cylinder barrel length direction
The through hole of extension, extend the piston rod outer end on the right side of cylinder barrel and be fixed with mounting structure, the mounting structure is located in described logical
In hole；Mounting structure includes connecting rod and installed part, and the installed part is connected by lug-mounted and threaded rod and formed, the installation
Auricle is connected as a single entity by bearing pin and the connecting rod.
The connector includes baffle plate, and right connector, the right connector and the work are fixed with the right side of the baffle plate
Stopper rod is threadedly coupled, and left connector is fixed with the left of baffle plate, the left connector is fixedly connected with the knocking gear.
The knocking gear includes being connected in guide rod on the left connector, the guide rod from left to right successively by
Optical axis section and spiro rod section are formed, and block is threaded with the spiro rod section, is slided in the optical axis section and is equipped with impact block, institute
State and draw ring is symmetrically arranged with impact block.
The block is double nut.
Fixes sleeve is fixed with the fixed seat right-hand member, the fixes sleeve is fastened by upper and lower two halves circular slab and formed.
The invention has the advantages that constant tension can be not only provided by piston rod to hinge, while knocking gear
Also hinge can be made to be loosened with hinge hole junction, i.e. tension by piston rod to transmission vibratory impulse power at hinge
Hinge is acted on simultaneously with vibratory impulse power, and guarantee is pulled out axle and smoothly extracted out of hinge hole, improves operating efficiency.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the structural representation of fixes sleeve of the present invention.
Embodiment
As shown in figure 1, hydraulic support hinge of the present invention pulls out shaft device, including hydraulic jack, hydraulic jack includes
Cylinder barrel 1 and piston rod 2, the left and right ends of piston rod 2 extend outward cylinder barrel 1 respectively, extend the piston rod 2 in the left side of cylinder barrel 1
Outer end is fixed with knocking gear by connector, and connector includes baffle plate 8.1, and right connector is fixed with the right side of baffle plate 8.1
8.2, right connector 8.2 is threadedly coupled with piston rod 2, and left connector 8.3, the left spiral shell of connector 8.3 are fixed with the left side of baffle plate 8.1
Line is connected with knocking gear, and left connector 8.3 and right connector 8.2 are thread head, are easily installed, and baffle plate 8.1 also has limit
Position effect, prevents impact block 11 from sliding into the right on piston rod 2；Knocking gear includes being threaded on left connector 8.3
Guide rod, guide rod are made up of optical axis section 9.1 and spiro rod section 9.2 from left to right, and block 10 is threaded with spiro rod section 9.2,
Block 10 is double nut, has locking effect, prevents from loosening during vibration, is slided in optical axis section 9.1 and is equipped with impact block 11, hit
Draw ring 12 is symmetrically arranged with block 11, drawstring is provided with draw ring 12, pulls impact block 11 to hit block 10 by drawstring, makes to hit
Vibratory impulse power caused by hitting the shock block 10 of block 11 is transferred to hinge to be pulled out by piston rod 2；The right-hand member of cylinder barrel 1 is fixed with
Reservation 3, through hole 4 is offered along the length direction of cylinder barrel 1 in fixed seat 3, the right-hand member of piston rod 2 for extending the right-hand member of cylinder barrel 1 is fixed with
The mounting structure being connected with hinge to be pulled out, mounting structure are located in through hole 4；Mounting structure includes being connected in the right side of piston rod 2
The connecting rod 5 at end and the installed part formed that is connected by lug-mounted 6.1 and threaded rod 6.2, it is blind to offer installation in connecting rod 5
Hole, lug-mounted 6.1 are plugged in installing blind and are connected as a single entity by bearing pin 7 and connecting rod 5, and threaded rod 6.2 is with waiting to pull out hinge
Axle phase spiral shell connects, i.e., piston rod 2 is connected by mounting structure and hinge to be pulled out, and constant force is provided to pull out axle operation.
As shown in Figure 1 and Figure 2, fixes sleeve 13 is fixed with the right-hand member of fixed seat 3, fixes sleeve 13 is circular by upper and lower two halves
