Abstract
The utility model discloses a pump shaft sleeve expander and solves the problem that the existing shaft sleeve removal method easily causes damage to a shaft sleeve. The pump shaft sleeve expander comprises a round retainer disc, a jackscrew, a round clamp, a plurality of tension bars, and tension claws as many as the tension bars. The jackscrew is fixed at the center of the round retainer disc. The tension bars are evenly fixed on the periphery of the round retainer disc. Each tension claw comprises an arc side attaching to the outer wall of the shaft sleeve and upper and lower planes perpendicular to the side. The tension bars penetrate the upper and lower planes of the tension claws. The bottoms of the tension bars are fixed through screws. The round clamp penetrates gaps between the tension bars and the tension claws. The butt parts of the round clamp are fixedly connected through a screw. The pump shaft sleeve expander can be operated by one operator; the faces of the arc tension claws, in contact with the outer periphery of the shaft sleeve, are provided with wear-resistant rubber, so that damage of the pump shaft sleeve is avoided effectively, and repairing cost for damages caused by the use of the traditional removal methods during the removal process of the pump shaft sleeve is saved.
Description
Technical field
The servicing unit using when the utility model relates to a kind of maintenance of equipment, when concrete is maintenance or maintenance pump apparatus, assists the device while getting axle sleeve.
Background technology
When centrifugal pump is keeped in repair and maintained, getting axle sleeve is a difficult problem.Common way is to coordinate with hand hammer and bottle opener, the outer rim of directly pounding axle sleeve, and a result of doing is like this often to make axle sleeve outer rim occur scar, overexertion can directly be smashed axle sleeve.Also have plenty of, because the outer rim of axle sleeve directly contacts with the filler in stuffing-box, if there is the belt polishing scratch that the depth is different in the outer rim of axle sleeve, will affect the rear axial sealing of equipment, thus the increase of leaking while causing centrifugal pump running and the reduction of outlet pressure.
Summary of the invention
The purpose of this utility model is to provide a kind of pump shaft cover chest expander, while using this pump shaft cover chest expander to get axle sleeve, can effectively avoid scratching axle sleeve outer rim, has further saved because pump shaft overlaps damage and has weighed fresh processed expense.
For achieving the above object, the technical solution adopted in the utility model is: a kind of pump shaft cover chest expander, comprise circular block plate, jackscrew, circular clamp, some stayed masts and with the pulling force pawl of stayed mast equal number, wherein, jackscrew is fixed on the center of circular block plate, and stayed mast is circumferentially evenly fixing along circular block plate; Described pulling force pawl, comprise one with the circular arc side of axle sleeve outer wall laminating and with the upper and lower plane of this lateral vertical, stayed mast is through the upper lower plane of pulling force pawl, bottom is screwed; Described circular clamp, successively through the space between stayed mast and pulling force pawl side, the joint of circular clamp adopts screw to be fixedly connected with.
Beneficial effect: when centrifugal pump is keeped in repair and maintained, use pump shaft cover device chest expander, one people can operate, utilize circular clamp by three arc pulling force pawls, be fastened on axle sleeve outer rim, on three arc pulling force pawls and axle sleeve outer rim contact-making surface, wear-resisting rubber is housed, has effectively avoided the damage of pump shaft cover, saved the expense that need repair because of the improper damage causing of method for dismounting in the past in pump shaft cover unloading process.
Accompanying drawing explanation
Fig. 1 is the structural representation of pump shaft cover chest expander of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1: a kind of pump shaft cover chest expander, comprise circular block plate 2, jackscrew 1, circular clamp 5, some stayed masts 3 and with the pulling force pawl 4 of stayed mast with quantity, jackscrew 1 is fixed on the center of circular block plate 1, stayed mast 3 is fixed along the even circumferential of circular block plate 2; Described pulling force pawl 3, comprises a circular arc side 41 of fitting with axle sleeve outer wall and the upper and lower plane vertical with this side 41, and stayed mast 3 is through upper plane and the lower plane of pulling force pawl 4, and bottom is fixing with screw 7; Described circular clamp 5, through the space between stayed mast 3 and pulling force pawl side 41, the joint of circular clamp is fixedly connected with by screw rod 6 successively.
During use, unclamp the joint of circular clamp; pulling force pawl is fitted in to axle sleeve outer wall along axle sleeve circumference; and between axle sleeve outer wall and pulling force pawl side, wear-resisting rubber is set; lock circular clamp; then rotate jackscrew, and by stayed mast, apply the active force of drawing axle sleeve, axle sleeve takes off the most at last; because there is the protection of wear-resisting rubber, axle sleeve outer rim can not come to harm.
Claims (1)
1. a pump shaft cover chest expander, comprise circular block plate, jackscrew, circular clamp, some stayed masts and with the pulling force pawl of stayed mast equal number, it is characterized in that: described jackscrew is fixed on the center of circular block plate, stayed mast is fixed along the even circumferential of circular block plate; Described pulling force pawl, comprise one with the circular arc side of axle sleeve outer wall laminating and with the upper and lower plane of this lateral vertical, stayed mast is through the upper lower plane of pulling force pawl, bottom is screwed; Described circular clamp, successively through the space between stayed mast and pulling force pawl side, the joint of circular clamp adopts screw to be fixedly connected with.
