Description
Technical Field
The utility model relates to an oil gas field borehole operation technical field, in particular to openly hang lift cylinder end cover and dismantle specialized tool.
Background
The end cover of the front-hung lifting oil cylinder is large in size, the diameter of the end cover is 300mm, and the oil cylinder barrel and the end cover are rusted due to long-time use between the mutually matched thread glue and the thread, so that the defect that the matching force between the oil cylinder end cover and the oil cylinder barrel is overlarge during disassembly is caused, and the opening is difficult.
At present, two methods are mainly adopted for disassembling an end cover of a front-face lifting oil cylinder. The method comprises the following steps: when tools such as a hook wrench, a T-shaped tool and the like are used for disassembling the lifting oil cylinder end cover, two persons are needed to be matched, but once the method is adopted, the large hammer cannot be disassembled enough, personal injury accidents are easy to happen, and the oil cylinder end cover is damaged. The second method comprises the following steps: two No. 1 gas cutting moments are used for heating the oil cylinder end cover to the surface to be red and then the oil cylinder end cover is detached, but the oil cylinder barrel and the end cover deform and the material annealing can be caused by the adoption of the method due to overhigh temperature and uneven heating.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a simple structure, convenient and safe in utilization's front hangs and lifts hydro-cylinder end cover and dismantles specialized tool.
Therefore, the utility model discloses technical scheme as follows:
a special tool for disassembling an end cover of a front-lift oil cylinder comprises a fixing ring and two strip-shaped handles which are arranged and fixed on the outer wall of the opposite side of the fixing ring; the side wall of the fixing ring is provided with a plurality of radial screw holes which are uniformly distributed along the circumferential direction, and a bolt which is matched with the internal thread of each screw hole is inserted in each screw hole.
Preferably, the number of the radial screw holes formed in the fixing ring is four.
More preferably, four every two of screw are a set of and are located the offside, and the axis mutually perpendicular of two sets of screws makes solid fixed ring pass through when the bolt fastening is followed at the end cover, and when two handles were dismantled the end cover, the atress all around was even.
Preferably, the inner diameter of the fixing ring is 10mm larger than the outer diameter of the end cover.
Preferably, the length of the strip-shaped handle is 360 mm.
The special tool for disassembling the end cover of the front-lift oil cylinder is firmly fixed with the end cover through the fixing ring and the mutually matched bolts, the end cover is stressed uniformly and is not easy to slip, gas welding cutting torch heating and manual support are not needed in the disassembling process, a large hammer is directly adopted for striking, the load requirement can be met, and the end cover can be disassembled conveniently and safely; and the oil cylinder barrel and the end cover are not easy to deform in the dismounting process.
Drawings
FIG. 1 is a schematic structural view of a special tool for disassembling an end cover of a front-lift cylinder according to the present invention;
FIG. 2 is a schematic structural view of the special tool for disassembling the end cover of the front-lift cylinder of the present invention without bolts;
fig. 3 is a schematic view of the special tool for disassembling the end cap of the front-lift cylinder of the present invention cooperating with the front-lift cylinder.
Detailed Description
The present invention will be further described with reference to the following drawings and specific examples, but the following examples are by no means limiting the present invention.
As shown in fig. 1-2, the tool special for disassembling the end cover of the front-lift oil cylinder applied to the end cover with the diameter of 300mm comprises a fixing ring 1 and two strip-shaped handles 2 respectively arranged on the outer walls of the opposite sides of the fixing ring 1; wherein,
the fixing ring 1 is an annular body with the inner diameter of 310mm, the outer diameter of 360mm and the axial height of 40mm, and the side wall of the fixing ring 1 is provided with four radial screw holes 3 uniformly distributed along the circumferential direction; specifically, the inner diameter of each radial screw hole 3 is 18 mm;
in four screw holes 3 arranged on the fixing ring 1, every two screw holes are formed in a group and positioned on the opposite side, and the central axes of the two groups of screw holes 3 are vertical to each other, so that the subsequent fixing ring is fixed on the end cover to ensure that the force is uniformly distributed;
a bolt 4 matched with the internal thread of the screw hole 3 is inserted in each screw hole 3; specifically, the model number of the bolt 4 is M18 × 50;
the two strip-shaped handles 2 are respectively fixed on the outer walls of the opposite sides of the fixing ring 1 in a welding mode; specifically, the length of each handle 2 is 360mm, so that the large hammer has enough torque when knocking the end of the wrench, and the corresponding load requirement is met.
As shown in fig. 3, when the special tool for detaching the end cover of the front-lift cylinder is used, the fixing ring 1 is penetrated on the end cover of the front-lift cylinder, and then the screws 4 arranged in the four radial screw holes 3 are screwed down, so that the end parts of the screws 4 are tightly pressed on the side edge of the end cover, and meanwhile, when the screws 4 are screwed down, the length of each screw 4 extending into the fixing ring 1 is basically consistent, so that the stress is uniform; then, a big hammer is adopted to beat the end part of the handle 2 to loosen the threads which are matched with the edge of the oil cylinder, until the end cover is detached from the oil cylinder.
The special tool for disassembling the front-lift oil cylinder end cover can be widely applied to disassembling and assembling oil cylinder end covers of other various mechanical equipment by changing the inner diameter size of the fixing ring.
The above-mentioned embodiments are only for describing the preferred embodiments of the present invention, but not for limiting the concept and scope of the present invention, and without departing from the design concept of the present invention, ordinary engineers in the art can be widely applied to the disassembling and assembling operations of oil cylinder end caps of other various mechanical devices by changing the inner diameter of the fixing ring; also can be right the utility model discloses a various deformation and improvements that technical scheme made all should belong to the utility model discloses a protection scope.
