Abstract
The utility model discloses a push-pull hammer. The push-pull hammer comprises a slide bar made of round bar steel with the diameter of 50mm and the length of 500mm. A slide hammer is sleeved on the slide bar, a round stop iron with the diameter of 70mm is welded on the back end of the slide bar, a threaded hole with the diameter of 20mm and the depth of 75mm is machined on the front end of the slide bar, and a threaded rod is arranged on the threaded hole in a matching mode. When the push-pull hammer is used, the threaded hole with the diameter of 20mm is drilled on a hinge pin of an integrated excavator through an arch awl, one end of the threaded rod is connected with the hinge pin, the other end of the threaded rod is connected with the threaded hole of the push-pull hammer; and then a construction worker pulls the slide hammer to strike the stop iron on the slide bar back and forth, and therefore acceleration acting force is generated, and the hinge pin can be pulled out easily.
Description
Technical field
The utility model relates to the specific purpose tool for the withdrawing bearing pin.
Background technology
Fully-mechanized digging machine is a kind of comprehensive heading equipment, the driving of the preparatory working that is mainly used in mining.Because fully-mechanized digging machine moves use for a long time in the down-hole, these connect abrasion deformation, corrosion of bearing pin; Bearing pin be difficult to be extracted out when fully-mechanized digging machine was removed, and caused difficulty that fully-mechanized digging machine removes and the prolongation of construction period.When the push-and-pull hammer is removed for fully-mechanized digging machine exactly, a kind of novel practical instrument of the position bearing pin withdrawings such as cutting units, shovel board section.
The utility model content
Be difficult to the problem of extraction for solving the fully-mechanized digging machine bearing pin, the utility model has designed the specific purpose tool that is used for the withdrawing bearing pin--the push-and-pull hammer.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of push-and-pull hammer, it comprises that a diameter is that 50mm, length are the slide bar of the round steel making of 500mm, put a sliding hammer on the slide bar, being welded with diameter in the slide bar rear end is the circular buting iron of 70mm, be processed with the screwed hole of diameter 20mm, degree of depth 75mm at the slide bar front end, a supporting threaded rod on the screwed hole.
The utility model has the advantages that: during use, go out first the screwed hole of diameter 20mm with the arch bradawl at the bearing pin of fully-mechanized digging machine, threaded rod one end is connected bearing pin, the other end is connected with the screwed hole of push-and-pull hammer, then the workmen spurs sliding hammer clash into back and forth buting iron on slide bar, produce an acceleration active force, be easy to bearing pin is extracted.
Description of drawings
Fig. 1 is the front view of the utility model embodiment.
Marginal data, 1-slide bar, 2-sliding hammer, 3-buting iron, 4-screwed hole, 5-threaded rod, 6-bearing pin.
The specific embodiment
Specify the present embodiment below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of push-and-pull hammer, it comprises that a diameter is that 50mm, length are the slide bar 1 of the round steel making of 500mm, put a sliding hammer 2 on the slide bar 1, be welded with the circular buting iron 3 that diameter is 70mm in slide bar 1 rear end, be processed with the screwed hole 4 of diameter 20mm, degree of depth 75mm at the slide bar front end, a supporting threaded rod 5 on the screwed hole 4.
During use, go out first the screwed hole of diameter 20mm at the bearing pin 6 usefulness arch bradawls of fully-mechanized digging machine, threaded rod 5 one ends are connected bearing pin 6, the other end is connected with the screwed hole 4 of push-and-pull hammer, then the workmen spurs sliding hammer 2 clash into back and forth buting iron 3 on slide bar 1, produce an acceleration active force, be easy to bearing pin 6 is extracted.
