The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Referring to Fig. 1 to Fig. 7; The described a kind of hydraulic pin remover that is used for the hydraulic support dismounting of the utility model; The screw connector 1, the end that comprise connector 1-1 and cylinder seat 1-2 composition are takeed on nut 6 and the passing cylinder 2 that cylinder seat 1-2 is connected through bolt 5 and band, and it is characterized in that: the other end of said passing cylinder 2 is connected through the centre bore of three lobe dish 3-7 of a nut 7 and a support sleeve assembly 3; Also comprise a hydraulic package 4; This hydraulic package is made up of with the high-pressure rubber pipe 4-3 that is connected with the cauda valve triangle riser 4-1, the cauda valve 4-2 that is located on the triangle riser, and its triangle riser 4-1 is connected with the middle part of support sleeve assembly 3, cauda valve 4-2 joins with the pressure source that pumping plant provides, high-pressure rubber pipe 4-3 is connected with the rod chamber of passing cylinder 2, the rodless cavity connection.
The extension bar tube 3-4 that said support sleeve assembly 3 is connected with three lobe dishes by three lobe dish 3-7, three ends, three screw rod 3-5 that cooperate with three extension bar tube 3-4 inwalls respectively, three long nut 3-3 that cooperate with part that three screw rods stretch out the extension bar tube respectively, three expansion bearing pawl 3-1 that are connected with three screw rod 3-5 respectively through pin 3-2, three end a screw 3-8 and twice that are located at respectively on three extension bar tube 3-4 are enclosed within the outer hoop 3-6 of three extension bar tube 3-4 and form.
The screwed hole that the end of said connector 1-1 passes the through hole of cylinder seat 1-2 bottom centre and the shaft end of being pulled pin is connected.
The end face of the bearing claw 3-1 of said support sleeve assembly 3 is provided with reticulate pattern; Its effect is when this hydraulic pin remover is pulled pin, and three bearing claws are close to the hydraulic support side plate under the effect of long nut pretightning force, and it can not skidded.
The utility model mainly contains following innovation part:
Support sleeve 3 Front-end Design have three expansion bearing pawl 3-1, and bearing claw 3-1 end face does that reticulate pattern is arranged, and makes pin removal when pulling pin, and three bearing claw 3-1 are close to rack side plate under the effect of long nut 3-3 pretightning force.Like this, when pulling pin, pin removal can not skid on the rack side plate face.
Is the bearing pin length of desiring to extract L=750, and pin removal passing cylinder 2 strokes have only 460, how bearing pin are all pulled out the place? Here adopted the mode that distributes and pull pin.
Extract for solving the random length bearing pin of length in 800 scopes, adopted long nut 3-3 in the support sleeve 3, screw rod 3-5 mechanism can stretch out expansion bearing pawl 3-1 arbitrarily.And the manufacturability of considering 3-4 making screw thread is poor, thus made long nut 3-3, and 3-4 only uses a steel pipe, endoporus need not be processed, and has avoided the trouble of processing slim screw like this.
This pin removal operation principle, step is following:
(1) selects nipple 1-1 according to product bearing pin screw size;
(2) nipple 1-1 is contained on the cylinder seat 1-2, again screw connector 1 is contained on the pin removal;
(3) will drive a vehicle or other boom hoistings are sling pin removal, and guarantee pin removal axis and product bearing pin axis coaxle;
(4) threaded connector 1-1 is connected with product bearing pin screw, and screws up with a wrench;
(5) the pressure source flexible pipe that the interface on the cauda valve 4-2 and pumping plant is provided joins;
(6) move cauda valve 4-2, make and pass cylinder 2 rodless cavity feed liquors, rod chamber returns liquid, and support sleeve 3 is moved to right.
(7) move cauda valve 4-2 to meta, three screw rod 3-5 in the support sleeve 3 are pulled out, and make claw 3-1 end face be close to product bearing pin side plate on every side, and tighten long nut 3-3, make claw 3-1 apply a pretightning force side plate.
(8) court moves direction in the opposite direction with step (6); Move cauda valve 4-2, make and pass cylinder 2 rod chamber feed liquors, rodless cavity returns liquid; At this moment support sleeve 3 is motionless; The piston rod of passing cylinder 2 is motionless, and cylinder body and the screw connector 1 of passing cylinder 2 move towards the direction away from bearing pin, thereby bearing pin is pulled out under nipple 1-1 pulling.
Extract length L greater than 460 bearing pin, repeating step (6), (7), (8) step are extracted bearing pin step by step.
The protection domain of the utility model is not limited to the above embodiments, and obviously, those skilled in the art can carry out various changes and distortion and not break away from the scope and the spirit of the utility model the utility model.If these changes and distortion belong in the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and is out of shape interior.
