Abstract
The utility model relates to an improved hydraulic puller, which belongs to the technical field of machine maintenance tools and aims to solve the technical problem of providing a hydraulic puller which still can normally work when a coupling is overlong. The utility model has the technical scheme that the improved hydraulic puller comprises a support, a propelling rod and a claw. The improved hydraulic puller is improved in such a manner that the front end of the propelling rod is connected with a detachable extension rod; the detachable extension rod comprises a connecting nut and a bolt; the connecting nut is welded at the front end of the propelling rod, and the bolt is screwed in the connecting nut; the detachable extension rod can also be a loop bar; the loop bar is a cylindrical rod; the rear end of the loop bar is provided with a cylindrical groove; the diameter of the groove is matched with the front end of the propelling rod; and the groove is sleeved at the front end of the propelling rod. By adopting the hydraulic puller with the structure, when the coupling is pulled, if the propelling rod is not enough in length when being jacking to the end, the bolt with proper length is screwed on the connecting nut, or the loop bar is sleeved at the front end of the propelling rod. The improved hydraulic puller saves time and labor and saves the maintenance cost.
Description
Technical field
The utility model relates to a kind of yard apparatus that draws that pulls out the shaft coupling use, belongs to the mechanical maintenance tool in use technical field.
Background technology
Big-and-middle-sized chemical enterprise all is continuous production generally, and after equipment broke down, maintenance in time recovered extremely important, and the maintenance tool handy important step that guarantees overhaul efficiency and quality especially easy to use.In chemical enterprise, adopted a large amount of centrifugal pumps, various pump apparatus such as magnetic drive pump when motor in the equipment breaks down when keeping in repair, usually need to draw a yard device to rise with hydraulic pressure and pull out shaft coupling and bearing.But when practical operation, can run into because of shaft coupling long, the propelling masthead that draws yard device long not enough problem to the end the time, need to change and bigger to draw yard device shaft coupling could be risen fully to pull out, cause the shaft coupling deformed damaged easily if adopt hammer to pound, both increased maintenance cost, time-consuming again, effort, very inconvenient, be necessary drawing a yard device to improve.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of improved hydraulic pressure that still can normally use and draws a yard device when shaft coupling is long.
The technical scheme that solves the problems of the technologies described above is:
A kind of improved hydraulic pressure draws a yard device, and it is made up of support, pushing ram, hook, and its improvements are, is connected with dismountable extension bar at the front end of pushing ram.
Above-mentioned improved hydraulic pressure draws a yard device, and described dismountable extension bar is attaching nut and bolt, and the attaching nut is welded on the front end of pushing ram, and bolt is spun among the attaching nut.
Above-mentioned improved hydraulic pressure draws a yard device, and described dismountable extension bar is a loop bar, and loop bar is a cylindrical bar, and there is cylinder shape groove the rear end of loop bar, and the diameter of groove and the front end of pushing ram are complementary, the pushing ram front end that groove is enclosed within.
Adopt the hydraulic pressure of this structure to draw a yard device, rising when pulling out shaft coupling, length is not enough to the end if advance masthead, the bolt of screwing on the attaching nut and being of convenient length, perhaps loop bar is just passable on the front end sleeve of pushing ram, save time, laborsaving, saved maintenance cost again.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an another kind of structural representation of the present utility model.
Mark is as follows among the figure: support 1, pushing ram 2, hook 3, attaching nut 4, bolt 5, loop bar 6.
The specific embodiment
The utility model is that a kind of improved hydraulic pressure draws a yard device, and it is made up of support 1, pushing ram 2, hook 3, and its improvements are, is connected with dismountable extension bar at the front end of pushing ram 2.
Fig. 1 shows, dismountable extension bar is the attaching nut 4 with the identical size of pushing ram diameter of front end welding who draws yard device pushing ram 2 at existing hydraulic pressure, rising when pulling out shaft coupling, if length is not enough to the end to advance masthead, the bolt 5 that is of convenient length screwed on attaching nut 4 is just passable, very simple and convenient.
Fig. 2 shows that dismountable extension bar is a loop bar 6, and loop bar 6 is a cylindrical bar, and there is cylinder shape groove the rear end of loop bar 6, and the front end of the diameter of groove and pushing ram 2 is complementary.During use, pushing ram 2 front ends that loop bar 6 is enclosed within.In order to prevent that loop bar 6 from coming off, can also bore a hole in the side of loop bar groove, put screw thread, be screwed into jackscrew and get final product.
Adopt the hydraulic pressure of this structure to draw a yard device, rising when pulling out long shaft coupling, save time, laborsaving, saved maintenance cost again.
