Description
Technical field
The utility model relates to detaching device for pin shaft technical field, in particular to a kind of pin pulling device.
Background technology
In plant equipment maintenance, repair procedures, often to dismantle bearing pin, dismantle the device of bearing pin at present or rely on manpower, cause labor strength large, and this method for dismounting efficiency be lower; Versatility is bad, needs to change whole provision for disengagement, not only cost of idleness when dismantling the bearing pin of different size, and unclear be disassembled bearing pin specification time, need the provision for disengagement of carrying Multiple Type, it is very inconvenient to carry.
Utility model content
For above-mentioned problems of the prior art, the utility model provides a kind of easy to use, can extract bearing pin, the good pin pulling device of versatility fast.
For achieving the above object, the utility model provides following technical scheme:
The utility model pin pulling device comprises super-pressure pump, hydraulic nut, support set and removal rod, removal rod comprises the body of rod and pulls out shaft member, body of rod one end is provided with the first screw thread matched with hydraulic nut, the other end is provided with and the second screw thread pulling out shaft member one end and match, pull out the shaft member other end and be provided with the 3rd screw thread matched with split bearing pin, support set is provided with through hole, and removal rod is through through hole, support set is between hydraulic nut and split bearing pin, and super-pressure pump is connected with hydraulic nut.The utility model pin pulling device is easy to use, can be extracted by bearing pin fast; And, the removal rod of pin pulling device comprises can two parts of disassembled and assembled freely combination, can according to the difference being disassembled bearing pin aperture, select to pull out shaft member accordingly and the body of rod is combined into removal rod, versatility is fine, it also avoid the cost waste changed whole removal rod and bring.
Further: the body of rod comprises nut segment, interlude and linkage section, above-mentioned first screw thread is arranged on nut segment, and the second screw thread is arranged on linkage section, interlude longitudinal section is trapezoidal, be preferably isosceles trapezoid, middle segment length limit is connected with nut segment, and interlude minor face is connected with linkage section.What be connected with linkage section pulls out the bolt that shaft member can select fine thread, is conducive to cost-saving.
Further: pin pulling device also comprises distance pad, distance cushion cover is contained on removal rod, and distance pad is between hydraulic nut and support set.When removal rod can not meet the stroke needed for dismounting bearing pin, by the distance pad increasing right quantity, bearing pin can be pulled down.Distance pad is located between hydraulic nut and support set, instead of be located between support set and split bearing pin, the distance pad of minor diameter is set like this, both can be cost-saving, distance pad can be avoided again to be arranged between support set and split bearing pin to the inconvenience that dismantlement work is brought.
Further: super-pressure pump is super-pressure handlance.

Detailed description of the invention
The technical solution of the utility model is understood better in order to make those skilled in the art; below in conjunction with accompanying drawing of the present utility model; clear, complete description is carried out to the technical solution of the utility model; based on the embodiment in the application; other roughly the same embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all should belong to the scope of the application's protection.
As Figure 1-3, a kind of pin pulling device, comprise super-pressure handlance (not shown), hydraulic nut 1, support set 2 and removal rod 3, described removal rod 3 comprises the body of rod and pulls out shaft member 4, the described body of rod comprises nut segment 5, interlude 6 and linkage section 7, described nut segment 5 is provided with the first screw thread 9 matched with hydraulic nut 1, described interlude 6 is arranged between nut segment 5 and linkage section 7, interlude 6 longitudinal section is isosceles trapezoid, the long limit of interlude 6 is connected with nut segment 5, and interlude 6 minor face is connected with linkage section 7.So, what be connected with linkage section 7 pulls out the bolt that shaft member 4 can select fine thread, is conducive to cost-saving.Described linkage section 7 is provided with and the second screw thread (not shown) of pulling out shaft member 4 one end and matching, described shaft member 4 other end that pulls out is provided with the 3rd screw thread 12 matched with split bearing pin 11, described support set 2 is provided with through hole 8, removal rod 3 is through through hole 8, support set 2 is between hydraulic nut 1 and split bearing pin 11, and super-pressure handlance is connected with hydraulic nut 1.Pin pulling device can also comprise distance pad 10, and described distance pad 10 is sleeved on removal rod 3, and described distance pad 10 is between hydraulic nut 1 and support set 2.When removal rod 3 can not meet dismounting demand, dismounting can be completed by the distance pad 10 increasing right quantity.The utility model pin pulling device is easy to use, can be extracted by bearing pin fast; And, the removal rod 3 of pin pulling device comprises can two parts of disassembled and assembled freely combination, can according to the difference being disassembled bearing pin 11 aperture, select to pull out shaft member 4 accordingly and be combined into removal rod 3 with the body of rod, versatility is fine, it also avoid the cost waste changed whole removal rod 3 and bring.
During use, first determine split bearing pin 11 fabrication hole size Selection supporting pull out shaft member 4, shaft member 4 will be pulled out and be assembled into removal rod 3 with the body of rod; Then, shaft member 4 other end will be pulled out and be disassembled bearing pin 11 and be connected, support set 2 will be sleeved on removal rod 3, now, owing to cannot determine to suppress stroke needed for dismounting hinge pin, temporarily not mounting distance pad 10.Finally, hydraulic nut 1 is connected with the nut segment 5 of removal rod 3, super-pressure handlance is connected with hydraulic nut 1, carries out and suppress preparation.Repeatedly pull the handle of super-pressure handlance, to the inner oil cylinder pressurization of hydraulic nut 1, make piston increase, drive removal rod 3 to rise.The tension travel once extracting a hydraulic nut 1 by bearing pin 11 often suppressed by super-pressure handlance to hydraulic nut 1, repeatedly suppress and bearing pin 11 can be extracted several times.But, suppress the restriction of stroke owing to being subject to removal rod 3 design, when suppress needed for dismounting hinge pin stroke be greater than removal rod 3 design suppress stroke time, complete whole process of suppressing and still bearing pin 11 cannot be extracted.At this moment then need the distance pad 10 installing right quantity to increase and suppress stroke.Such as, it is 84mm that stroke is suppressed in removal rod 3 design, and suppressing stroke needed for dismounting bearing pin is 108mm, then needing increases the stroke that distance pad 10 neutralizes the 24mm had more, and namely needs to superpose and installs the distance pad 10 that two pieces thickness is 12mm.Distance pad 10 is located between hydraulic nut 1 and support set 2, instead of be located between support set 2 and split bearing pin 11, the distance pad of minor diameter is set like this, both can be cost-saving, distance pad 10 can be avoided again to be arranged between support set and split bearing pin 11 to the inconvenience that dismantlement work is brought.
In addition, be to be understood that, although this description is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should by description integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
