Abstract

The utility model discloses a coupler dismounting device which has less possibility of damaging the assembling surface of a shaft and is high in dismounting efficiency. Two groups of units with the same structure are screwed as a whole back to back, wherein each unit comprises a splint, a cross beam and two stand columns; the upper ends of the two stand columns are respectively and correspondingly welded to both ends of the cross beam as a whole; the splint is welded to the lower ends of the two stand columns as a whole; the stand columns are provided screw holes; the splint is provided with semicircular notches; and the notches on the splint are spliced into a circular hole after two groups of units are combined. By utilizing the coupler dismounting device, the notches on the splints are spliced into circular holes, the shaft in the coupler passes through the circular hole, the device mounted on the shaft is arranged on the inner side of the splint, the front end of a hydraulic jack supports on the shaft, and the rear end of the hydraulic jack is arranged on the cross beam; as the movement of the device is restricted by the splint, the shaft and the device are forced to move relative to each other, and finally the shaft is dismounted from the device.

Description

Detaching device for coupling

Technical field

The utility model relates to a kind of instrument, particularly a kind of device of dismounting couplers spare.

Background technology

At mechanical field, a large amount of parts that cooperate with axle are arranged, when axle or the parts that cooperate with axle go wrong, need the parts changing axle or cooperate with axle, at this moment, axle need to be unloaded from the parts that cooperate with axle.Now the instrument of dismantling vertically parts commonly used draws horse by what three claws or two claws formed, mainly is made of swing handle, threaded rod and pulling claw.This instrument is usually used in dismantling assemble under bearing and the normal temperature little wheel etc. is cooperated the parts that are not very tight with axle.And for adopting hot assembly technology to be installed in large aperture shaft coupling device on the axle, owing to adopt interference fit, and outside dimension is also larger, and above-mentioned instrument is subjected to the impact of pulling claw intensity, length and claw rigidity, can not be used for the dismounting of this base part.Also do not have at present special-purpose extracting tool, can only adopt destructive method for dismounting, not only easily damage the fitting surface of axle, and removal efficiency is not high yet.

Summary of the invention

The purpose of this utility model provides a kind of fitting surface and higher detaching device for coupling of removal efficiency of not easy damaged axle.

The technical solution of the utility model is: being spirally connected back-to-back by the unit of two groups of same structures is integrated; Each unit comprises clamping plate, crossbeam and two columns, and the upper end of two columns is welded as a whole correspondingly with the two ends of crossbeam respectively, and the lower end of clamping plate and two columns is welded as a whole, and column is provided with screw, has semicircle breach on the clamping plate; Breach after two groups of unit combination on its clamping plate is combined into and is circular hole.

Because the structure that adopts crossbeam, column and clamping plate to be welded as a whole in the utility model, and the breach of two clamping plate is combined into circular hole, can be easily the axle of shaft coupling device be passed circular hole, and make the device that is contained on the axle place clamping plate inboard, front end with hydraulic jack withstands on the axle, and the rear end of hydraulic jack is sitting on the crossbeam, because clamping plate have limited the motion of device, force axle and device generation relative motion, axle is disassembled from device.Adopt this mode to dismantle, firmly evenly, application of force direction with axially overlap, be difficult for making the installed surface of axle impaired, and, the frictional force less of axle and device, removal efficiency is higher.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the STRUCTURE DECOMPOSITION schematic diagram of Fig. 1;

Fig. 3 is the structural representation at another visual angle of the utility model;

Fig. 4 is the utility model working state schematic representation.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail, but does not consist of any restriction of the present utility model.Fig. 1 is to shown in Figure 3, and the utility model is spirally connected back-to-back by the unit of two groups of same structures and is integrated.Each unit comprises clamping plate 1, crossbeam 3 and two columns 2, the upper end of two columns 2 is welded as a whole correspondingly with the two ends of crossbeam 3 respectively, and the lower end of clamping plate 1 and two columns 2 is welded as a whole, and column 2 is provided with screw, have semicircle breach on the clamping plate 1, crossbeam 3 bottom surfaces are provided with semicircle centring ring.Breach on its clamping plate 1 after two groups of unit combination just in time is combined into circular hole, and the semicircle centring ring on its crossbeam 3 bottom surfaces just in time is combined into circle.Shown in Figure 4, during operation, the column 2 of two groups of unit is leaned on mutually, simultaneously the axle of shaft coupling device 5 is put into the breach of two clamping plate 1, make the device that is contained on the axle place clamping plate 1 inboard, then be fastened as a whole with the column 2 of bolt with two groups of unit, at this moment, the breach of two clamping plate 1 forms circular hole, makes axle be arranged in this circular hole.Front end with hydraulic jack 4 withstands on the axial end, and the rear end of hydraulic jack 4 is sitting in the centring ring on the crossbeam 3, to prevent the jack slippage.Because clamping plate 1 have limited the motion of device, jack forces axle and device generation relative motion, and axle ejects from device the most at last.Adopt this mode to dismantle, firmly evenly, application of force direction with axially overlap, be difficult for making the installed surface of axle impaired.Since axle eject direction basically be with axis in the same way, be not prone to the component of other directions, so the frictional force less of axle and device, removal efficiency is higher.
