Abstract
The utility model discloses a special tool for dismounting a pin shaft in a mine, which is characterized in that a support shaft is fixedly welded at the center of the bottom of the base and forms a T shape with a base; the bottom end of the support shaft is fixedly connected with a bolt which is fixedly connected with the pin shaft by screw threads; and manual screw jacks for jacking the base are arranged on two sides of the support shaft respectively. The special tool for dismounting the pin shaft is provided to meet the requirement of mechanical equipment in the mine on quick dismounting of the pin shaft, and can be used for dismounting the mechanical equipment in the mine efficiently and quickly.
Description
Technical field
The utility model relates to a kind of specific purpose tool that is used to remove bearing pin.
Background technology
Bearing pin is the connector that transmits motion and torque, supports rotary part, and is abominable, moist because of the colliery subsurface environment, makes a large amount of bearing pin corrosions serious, is difficult to directly remove.Also little because of the underground work space, large-scale instrument can't use, and causes some plant equipment bearing pins to be difficult to remove.
Summary of the invention
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of specific purpose tool of mine dismounting bearing pin is provided, removing difficult problem to solve mine machinery equipment bearing pin.
The utility model adopts following technical scheme for the technical solution problem:
The design feature that the utility model mine is removed the bearing pin specific purpose tool is: in the bottom centre of base; Be the fixing welding of T-shape one back shaft with said base; Be fixedly connected a bolt in the bottom of said back shaft, said bolt is fixedly connected with bearing pin through screw thread; Be respectively arranged with in the both sides of said back shaft and be used for base is formed the manual screw jack of shoring.
Compared with present technology, the utility model beneficial effect is embodied in.
1, the utility model is simple in structure, easy to use, especially is suitable for the little occasion in mine operation space.
2, use the utility model can greatly increase work efficiency, alleviate staff's working strength to the dismounting of mine machinery equipment bearing pin.
Description of drawings
Fig. 1 is the utility model structural representation;
Label among the figure: 1 base; 2 back shafts; 3 bolts; 4 manual screw jack; 5 bearing pins; 6 element of installation.
The specific embodiment
Referring to Fig. 1; The version of the specific purpose tool of mine pin removal axle is in the present embodiment: in the bottom centre of base 1; Be the fixing welding of T-shape one back shaft 2 with base 1, be fixedly connected a bolt 3 in the bottom of back shaft 2, bolt 3 is fixedly connected with the screwed hole at bearing pin 5 centers through screw thread; Be respectively arranged with in the both sides of back shaft 2 and be used for base 1 is formed the manual screw jack 4 of shoring.
Practical implementation, the specifications and models of bolt 3 be with the bearing pin 5 that will remove match, and form firm being threaded between the bearing pin 5.
During use,, be connected bolt 3 in the screwed hole of centre of bearing pin 5 with its external screw thread to the element of installation that is provided with bearing pin 56; Hand screw jack 4 is shored between base 1 and element of installation 6, shakes hand screw jack 4 through manual work and makes its piston rod elongation, until bearing pin 5 is transferred to.
