Abstract
The invention discloses a hydraulic shaft detaching device with a simple structure and convenient to use. The hydraulic shaft detaching device comprises a screw, wherein a first-level sleeve is sleeved on the right part of the screw; a lock nut is arranged on the left side of the first-level sleeve and is in threaded connection with the screw; a second-level sleeve is arranged on the left side of the lock nut and sleeved on the screw; a working hole is formed on the second-level sleeve and corresponds to the lock nut; and a hydraulic nut with an oil injection hole and a detaching hole is arranged on the left side of the second-level sleeve, and is in threaded connection with the screw.
Description
Technical field
The present invention relates to a kind of digging plant equipment, relate in particular to a kind of hydraulic pressure and take off axial organ.
Background technology
In the long-term production practice process, because the equipment service firing cycle is longer, cause pin, the beam warp of plant machinery structure often to occur damaging, need utilize the dismounting of manpower thick stick hammer at present, the dismounting difficulty was bigger when mode was changed at the scene, down-hole, the assembling difficulty, and the time is long, simultaneously easy damage equipment is so that influence is produced.
Summary of the invention
The purpose of this invention is to provide a kind of hydraulic pressure simple in structure, easy to use and take off axial organ.
For achieving the above object, the technical solution used in the present invention is: a kind of hydraulic pressure takes off axial organ, comprise screw rod, it is characterized in that: the right part of screw rod is with the one-level cover, the left design of one-level cover has locking nut, locking nut is connected with screw flight, the design of locking nut left has the secondary cover, the secondary cover is socketed on the screw rod, secondary puts and has working hole, working hole is corresponding with locking nut, and the left design of secondary cover has the hydraulic nut that has oil filler point and removal hole, and hydraulic nut is connected with screw flight.
Advantageous effect of the present invention is: because the right part of screw rod is with the one-level cover among the present invention, the left design of one-level cover has locking nut, locking nut is connected with screw flight, the design of locking nut left has the secondary cover, the secondary cover is socketed on the screw rod, secondary puts and has working hole, working hole is corresponding with locking nut, the left design of secondary cover has the hydraulic nut that has oil filler point and removal hole, hydraulic nut is connected with screw flight, utilized the oil cylinder Telescopic of hydraulic nut, pin to equipment, the axle part is stretched and is drawn, dismounting, so use the pin that the present invention can disassemble easily and fast needs dismounting, axle is very easy to dismounting and assembling in the equipment dimension inspection process, has changed traditional manpower thick stick hammer dismounting mode, shortened the take-down time, reduced personnel labor, improved on-the-spot efficiency and equipment operation rate, economic benefit is obvious.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a view of the present invention.
In the accompanying drawing: 1, screw rod; 2, hydraulic nut; 3, secondary cover; 4, locking nut; 5, one-level cover; 6, working hole; 7, oil filler point; 8, removal hole.
The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments:
The present invention as shown in Figure 1, 2, a kind of hydraulic pressure takes off axial organ, comprise screw rod 1, it is characterized in that: the right part of screw rod 1 is with one-level cover 5, the left design of one-level cover 5 has locking nut 4, locking nut 4 is threaded with screw rod 1, the design of locking nut 4 lefts has secondary cover 3, secondary cover 3 is socketed on the screw rod 1, have working hole 6 on the secondary cover 3, working hole 6 is corresponding with locking nut 4, and the left design of secondary cover 3 has the hydraulic nut 2 that has oil filler point 7 and removal hole 8, and hydraulic nut 2 is connected with screw flight.
In the present embodiment, locking nut 4 is a hydraulic nut.
Use when of the present invention, earlier screw rod is connected with pin that needs dismounting or axle, the one-level cover is installed successively, locking nut, secondary cover and hydraulic nut, utilize instrument to be equipped with tight locking nut and hydraulic nut simultaneously, connect the high pressure manual pump on the oil filler point with hydraulic nut then, utilize the high pressure manual pump to hydraulic nut oiling liquid, hydraulic nut is stretched out, the pulling screw rod, screw rod drives pin or the axially outer 3-5mm that pulls out, pin or axle disassemble and get final product, if do not disassemble, then locking nut are equipped with tight by working hole once more, with the hydraulic nut pressure release, the hydraulic nut stroke resets and is equipped with tightly again with secondary cover, repeats above step, up to sell or spool deviating to get final product.
Claims (2)
1. a hydraulic pressure takes off axial organ, comprise screw rod (1), it is characterized in that: the right part of screw rod (1) is with one-level cover (5), the left design of one-level cover (5) has locking nut (4), locking nut (4) is threaded with screw rod (1), the design of locking nut (4) left has secondary cover (3), secondary cover (3) is socketed on the screw rod (1), have working hole (6) on the secondary cover (3), working hole (6) is corresponding with locking nut (4), the left design of secondary cover (3) has the hydraulic nut (2) that has oil filler point (7) and removal hole (8), and hydraulic nut (2) is connected with screw flight.
