Abstract
The utility model relates to a bolt hydraulic dismounting device used for reaming, in particular to a bolt hydraulic dismounting device for reaming on the rigidity flange shaft coupler. The prior bolt hydraulic dismounting device for reaming is a hydraulic cylinder with a solid cylinder rod, and has the shortcoming that the device is not able to use without a support outside the shaft coupler flange. The utility model is characterized in that a frame body is provided with a supporting board at both ends, a hydraulic cylinder is arranged at one end of the supporting board, an axial blind hole is arranged on the cylinder rod of the hydraulic cylinder, an ejector rod opposite to the cylinder rod of the hydraulic cylinder is arranged on the other end, thus the dismounting device is able to use without the support outside the shaft coupler flange.
Description
The utility model relates to a kind of articulation hole bolt hydraulic detachment handler, the particularly articulation hole of rigid flanges shaft coupling bolt hydraulic detachment handler.
On the flange end face of rigid flanges shaft coupling, circumference be distributed with the articulation hole bolt that is used to connect drive flange half a coupler and passive flange half a coupler, separate two half a couplers and must dismantle the articulation hole bolt, existing articulation hole is a hydraulic cylinder that a piston rod that can protrudingly inwardly take in is arranged with bolt hydraulic detachment handler, piston rod is solid, must be during use with the cylinder body base of hydraulic cylinder, be resisted against with the shaft coupling flange end face on articulation hole with on other relative parts of bolt thread head, to bear the reaction force of hydraulic cylinder, then with pressure oil input hydraulic cylinder rodless cavity, the just protruding pushing tow articulation hole of piston rod bolt, so just, can be with articulation hole with ejecting the articulation hole of bolt on the shaft coupling flange end face, the deficiencies in the prior art part often is because articulation hole on the shaft coupling flange end face with bolt thread head opposite, does not have other parts that position suitable can bear reaction force again can not use as the reaction force support of hydraulic cylinder.
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and provides a kind of shaft coupling flange other parts in addition that do not need as the articulation hole of reaction force support bolt hydraulic detachment handler.
The purpose of this utility model can reach by following measure: there is the support body of support plate at two ends, one end support plate is equipped with a hydraulic cylinder, the piston rod of hydraulic cylinder has can hold the axial blind hole of articulation hole with bolt, and other end support plate is equipped with a push rod relative with the piston rod of hydraulic cylinder.
The utility model has following advantage compared to existing technology: support body is cross-placed on the shaft coupling flange, hydraulic cylinder is positioned at articulation hole with the big first end of bolt, there is the piston rod of axial blind hole to cover articulation hole and withstands the shaft coupling flange end face with the bolt major part, the push rod of the support body other end then withstands articulation hole bolt thread head, behind pressure oil input hydraulic cylinder rodless cavity, owing to withstanding flange end face, piston rod makes the opposite direction motion of cylinder body to piston rod, drive push rod pushing tow articulation hole bolt by support body, the reaction force of hydraulic cylinder acts on the shaft coupling flange end face by piston rod like this, also can not use so have other parts to make support beyond the shaft coupling flange.
Accompanying drawing is a front view of describing an embodiment of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing: there is support body＜1 of support plate at two ends 〉, there is a hole to be fitted with hydraulic cylinder＜2 on the one end support plate 〉, hydraulic cylinder＜2〉the piston rod that can protrudingly inwardly take in axial blind hole is arranged, the blind hole internal diameter is greater than articulation hole bolt large head external diameter, support body＜1〉have on the other end support plate one with hydraulic cylinder＜2 the relative screw of piston rod screw be equipped with one and relative with piston rod externally threaded push rod＜3 arranged, support body during use＜1〉be cross-placed on the shaft coupling flange, at this moment hydraulic cylinder＜2〉be positioned at articulation hole with the big first end of bolt, push rod＜3〉be positioned at articulation hole with bolt thread first end, with hydraulic cylinder＜2〉the piston rod blind hole cover articulation hole and withstand the shaft coupling flange end face with the bolt major part, rotate push rod＜3 then〉withstand articulation hole bolt thread head, then with pressure oil input hydraulic cylinder＜2〉rodless cavity, make hydraulic cylinder＜2 owing to piston rod withstands the shaft coupling flange end face〉cylinder body to the motion of the opposite direction of piston rod, hydraulic cylinder＜2〉cylinder body and support body＜1 so be support body＜1 that is combined as a whole in company with movement of cylinder block, thereby drive push rod＜3 the pushing tow articulation hole falls into the blind hole of piston rod with bolt until ejecting articulation hole on the shaft coupling flange end face.As long as with pressure oil input hydraulic cylinder＜2〉rod chamber inwardly takes in piston rod, with support body＜1〉take off from the shaft coupling flange, just the articulation hole that is disassembled can be taken out from the blind hole of piston rod with bolt.
Claims (1)
- A kind of articulation hole bolt hydraulic detachment handler, particularly the articulation hole of rigid flanges shaft coupling is with bolt hydraulic detachment handler, its hydraulic cylinder has a piston rod that can protrudingly inwardly take in, feature of the present utility model is the support body that there is support plate at two ends, one end support plate is equipped with a hydraulic cylinder, the piston rod of hydraulic cylinder has axial blind hole, and other end support plate is equipped with a push rod relative with the piston rod of hydraulic cylinder.
