The manual hydraulic pump is connected with the left end of the sleeve by threads; the lower and middle left part of the sleeve is provided with a groove, and the right end is provided with a through hole at a plane on which the right end and the groove are coaxial; the left set square is connected with the U-shaped right set square by the gemel; the upper end of the left soleplate integrated with the lower part of the left set square is provided with the short pin which is inserted into the groove of the sleeve; the lower end of the left soleplate is provided with the left pivot which is connected with the screw protector by threads; the upper end of the right soleplate integrated with the lower part of the right set square is provided with the long pin; the long pin is inserted into the through hole of the sleeve and is positioned by the upper stop pin and the lower stop pin; and the lower end of the right soleplate is provided with the right pivot. With the convenient, safe and quick operation, the utility model reduces the labor intensity of the workers, improves the work efficiency and saves the material expenses.
Description
Technical field
The utility model relates to pump apparatus coupling bolt extracting tools such as water flooding pump station, multi-purpose station, the poly-station of notes, particularly is a kind of coupling bolt extractor.
Background technology
In water flooding pump station, multi-purpose station, the poly-station of notes production process, the maintenance of pump is regular work, in real work in the past, the dismounting coupling bolt is the screw thread position of directly knocking bolt head artificially with hand hammer, treat that it just can unload after loosening, because the wretched insufficiency that this method for dismounting self exists, phenomenons such as regular appearance bent screws, screw thread damage, cause this bolt normally to use, waste time and energy, increase operator's labour intensity, increased the input of production cost.In the maintenance statistics to water injecting pump, the spoilage of its coupling bolt is on average more than 35%.Thereby prior art can not address the above problem preferably.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned weak point, designs a kind of coupling bolt extractor, the problem of coupling bolt dismounting difficulty and bolt failure when solving the pump maintenance.
Above-mentioned purpose is realized by following technical proposals:
The utility model comprises: hydraulic hand-pump, sleeve, left bottom plate, dump bolt, thread protector, left fulcrum, left set square, hinge, long pin, last alignment pin, right set square, following alignment pin, right base plate, right fulcrum; Its hydraulic hand-pump is threaded with the left end of sleeve, and left part has groove in sleeve following, right-hand member with the plane of the same axis of groove on be provided with through hole; Hinge links together the right set square of left set square and " U " shape, be provided with dump bolt with the left bottom plate upper end of left set square bottom one, dump bolt inserts in the groove of sleeve, dump bolt can slide along groove, the left bottom plate lower end is provided with left fulcrum, the left side fulcrum thread protector that is being threaded, thread protector play the effect of protection and transferring power to coupling bolt; Be provided with long pin with the right base plate upper end of right set square bottom one, long pin is inserted the through hole of sleeve by last alignment pin and following alignment pin location, and right base plate lower end is provided with right fulcrum.
According to the coupling bolt extractor that such scheme is made, easy to operate, safe, quick, keep in repair pump taking-up shaft coupling 12 bolts and dropped to 15 minutes by original average 40 minutes, alleviated working strength of workers, improved operating efficiency, the economical with materials expense
Description of drawings
