Abstract
The utility model relates to a dissembler for a piston clamp spring of a slush pump, which belongs to the technical field of oil drilling equipment, and relates to a device for assembling and dissembling a piston clamp spring of an oil-drilling slush pump. The dissembler comprises a hydraulic cylinder, a clamp spring pressing mold, a clamp spring guiding mold and a clamp spring dissembling mold. The utility model has the benefits that the piston clamp spring of the slush pump can be conveniently assembled and dissembled at a well site by utilizing the hydraulic principle, the operation is simple, the time and the labor are saved, and the safe production is ensured as well.
Description
Technical field
The utility model relates to a kind of dismounting mud piston jump ring device, belongs to the oil-well drilling equipment technical field.
Background technique
In Process of Oil Well Drilling, after mud piston rubber wearing and tearing, need to change piston, the integral replacing piston assembly, expense is higher, causes waste again, for addressing the above problem, on-the-spot on bench vice dismounting piston rubber, not only time-consuming took a lot of work but also very dangerous.
The model utility content
The purpose of this utility model is to provide a kind of dismounting mud piston jump ring replacer, can make things convenient at the scene, rapidly, dismounting mud piston jump ring effortlessly.
The purpose of this utility model is achieved in that a kind of mud piston jump ring replacer, comprise oil hydraulic cylinder, pressure jump ring mould, jump ring guiding mould and tear the jump ring mould open, the upper end of the vertical fixedly connected base assembly of described oil hydraulic cylinder, described pressure jump ring mould is arranged on the lower end of oil hydraulic cylinder, described pressure jump ring mould connects the piston rod of described oil hydraulic cylinder, and described pressure jump ring mould bottom is provided with circular cylindrical cavity; The top of described jump ring guiding mould is cylindrical body, described cylindrical external diameter is less than the internal diameter of described circular cylindrical cavity, the exterior edge face at the middle part of described jump ring guiding mould is the conical surface, the footpath, the end of the described conical surface is identical with the internal diameter of described circular cylindrical cavity, and the bottom of described jump ring guiding mould is second cylindrical body; Described top of tearing the jump ring mould open is the three cylindrical body, the external diameter of described three cylindrical body is identical with the internal diameter of described circular cylindrical cavity, described middle part of tearing the jump ring mould open is four cylindrical body of external diameter greater than described three cylindrical body, and described bottom of tearing the jump ring mould open is provided with paw.
In the time need tearing jump ring open at the scene, mud piston is placed on the base assembly, tearing the jump ring mould open is placed on above the mud piston, after suppressing, it is descending that cylinder pushes is torn the jump ring mould open, the rubber of compression mud piston makes jump ring withdraw from the jump ring groove of mud piston steel core, just can take out jump ring easily; When being installed spring, jump ring guiding mould is placed on the mud piston steel core, puts jump ring again, after suppressing, cylinder pushes presses the jump ring mould descending, guides mold pressing to the jump ring groove of mud piston steel core by jump ring jump ring.
The beneficial effects of the utility model are: utilize hydraulic principle can be in the well site dismounting mud piston jump ring easily, easy to operate, laborsaving saving time guarantees safety in production again.
For oil hydraulic cylinder after making release automatically resets, described oil hydraulic cylinder is the single-acting formula oil hydraulic cylinder that automatically resets.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Wherein, 1-joint, 2-oil hydraulic cylinder, 3-press jump ring mould, 4-connecting pin, 5-circular cylindrical cavity, 6-jump ring guiding mould, 601-cylindrical body, 602-second cylindrical body, 7-base assembly, 8-to tear jump ring mould, 801-three cylindrical body, 802-the 4th cylindrical body, 803-paw open.
Embodiment
As figure, a kind of mud piston jump ring replacer, comprise the formula oil hydraulic cylinder 2 that automatically resets, jump ring guiding mould 6 and tear jump ring mould 8 open, oil hydraulic cylinder 2 tops are provided with the joint 1 that links to each other with hydraulic power, oil hydraulic cylinder 2 bottoms are by the top of connecting pin 4 fixedly connected base assemblies 7, the piston rod of oil hydraulic cylinder 2 connects presses jump ring mould 3, presses jump ring mould 3 bottoms that circular cylindrical cavity 5 is set; The top of jump ring guiding mould 6 is cylindrical body 601, the external diameter of cylindrical body 601 is less than the internal diameter of circular cylindrical cavity 5, the exterior edge face at the middle part of jump ring guiding mould 6 is the conical surface, and the footpath, the end of the conical surface is identical with the internal diameter of circular cylindrical cavity 5, and the bottom of jump ring guiding mould 6 is second cylindrical body 602; The top of tearing jump ring mould 8 open is that the external diameter of three cylindrical body 801, the three cylindrical bodies 801 is identical with the internal diameter of circular cylindrical cavity 5, and the middle part of tearing jump ring mould 8 open is four cylindrical body 802 of external diameter greater than three cylindrical body 801, and the bottom of tearing jump ring mould 8 open is provided with paw 803.
In the time need tearing jump ring open at the scene, the mud piston assembly is placed on the base assembly 7, tear open above jump ring mould 8 is placed on, after suppressing, it is descending that oil hydraulic cylinder 2 promotes to tear jump ring mould 8 open, compression piston rubber, make jump ring eject the jump ring groove, just can take out jump ring easily, the formula that automatically resets after release oil hydraulic cylinder 2 automatically resets, when being installed spring, jump ring guiding mould 6 is placed on the mud piston steel core, puts jump ring again, after suppressing, oil hydraulic cylinder 2 promotes to press jump ring mould 3 descending, and jump ring is depressed in the jump ring groove of mud piston steel core by jump ring guiding mould 6.
