Description
Technical field
The utility model relates to a kind of double card iron blind hole bush drawing device, belongs to repair of machine specific purpose tool technical field.
Background technology
At present, in actual production, the dismounting of blind hole lining is a difficult problem for equipment repair always.Lining in blind hole can comprise: lining, bearing, valve seat etc., for example: when oil drilling and extracting equipment is repaired, the dismounting of the slush pump valve seat that becomes rusty dead, because equipment moves for a long time, lining and body corrosion are serious, and the dismounting of lining must be used specific purpose tool to complete.Need the dismounting of the specific purpose tool of larger pulling capacity compared with the blind hole lining of deep hole.
Summary of the invention
In order to overcome above-mentioned technical deficiency, the utility model provides double card iron blind hole bush drawing device, and this double card iron blind hole bush drawing device can easily take out blind hole lining, is more suitable for the taking-up of the darker blind hole lining in position.
The utility model solves the technical scheme that its technical problem adopts: screw rod lower end is provided with the collet that is greater than screw diameter, screw rod both sides, collet upper end are respectively equipped with gib, gib is distinguished hinged gib connecting rod up and down, two each relative gib connecting rods are hinged on screw rod by connecting rod steady pin, the center hinge of connecting rod torsion spring is connected on connecting rod steady pin, and the two ends of connecting rod torsion spring are stuck on gib connecting rod; Screw rod side is provided with side channel, is equipped with gib bracing wire in side channel, and gib bracing wire upper end is connected with annulus, and gib bracing wire lower end connects the upper end of gib; Screw rod upper end is provided with screw thread, and nut thread is connected on screw rod, and nut lower end is equipped with packing ring, and packing ring lower end is equipped with hydraulic jack.
The beneficial effects of the utility model are: this apparatus structure is simple and practical, and each component processing is simple, and volume is little lightweight, and practical function is good.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
Fig. 1 is the utility model double card iron blind hole bush drawing device work structuring figure.
