Abstract
The utility model relates to a hydraulic screw extractor, it includes pneumatic cylinder (1), pneumatic cylinder (1) front end is provided with plunger (2), plunger (2) are gone up the cover and are equipped with solid fixed ring (3), plunger (2) are connected through the screw thread with solid fixed ring (3), gu going up to connect, fixed ring (3) are provided with a plurality of jack catchs (4), pneumatic cylinder (1) rear end is provided with external joint (5), external joint (4) are gone up to connect through flexible rubber hose (6) and are provided with hydraulic hand pump (7). The utility model relates to a hydraulic screw extractor, it is connected with hydraulic hand pump through external joint for powered hydraulic pressure oil does not pass through the oily bag of hydraulic screw extractor itself, and pressure oil direct action is on hydraulic screw extractor work plunger, and the pulling force is big, has accelerated shaft coupling dismounting speed, has effectively promoted work efficiency.
Description
Technical field
This utility model is related to a kind of hydraulic screw extractor, belongs to and builds ship technical field.
Background technology
The existing hydraulic screw extractor in workshop（5T、10T）Totally six, usage frequency is high after purchase, in Ship's Repair operation process
For dismantling all kinds of Kao Bilin shaft couplings, because hydraulic screw extractor oil sac itself and hydraulic part have leakage problem, in independent oil sac
Will air inlet cause emptying phenomenon, often there is oil pressure and sets up difficult in Jing, the pulling force phenomenon such as not enough, general use requirement
Can not meet, multiple, costly, DeGrain is repaired in external coordination, repairing in original structure cannot thorough solve problem.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of hydraulic screw extractor for above-mentioned prior art, and it passes through
External connector is connected with hydraulic hand pump so that power fluid force feed is not by hydraulic screw extractor oil sac itself, pressure oil direct effect
On hydraulic screw extractor duty plunger, pulling force is big, accelerates shaft coupling dismounting speed, effectively improves work efficiency.
The technical scheme in the invention for solving the above technical problem is：A kind of hydraulic screw extractor, it includes hydraulic cylinder, institute
State hydraulic cylinder front end and be provided with plunger, retainer ring is set with the plunger, the plunger is connected with retainer ring by screw thread,
Multiple claws are connected with the retainer ring, the hydraulic cylinder rear end is provided with external connector, are led on the external connector
Cross rubber hose and be connected with hydraulic hand pump.
Compared with prior art, the utility model has the advantage of：
A kind of hydraulic screw extractor of this utility model, it is connected by external connector with hydraulic hand pump so that power fluid force feed
Not by hydraulic screw extractor oil sac itself, pressure oil is directly acted on hydraulic screw extractor duty plunger, and pulling force is big, accelerates shaft coupling
Dismounting speed, effectively improves work efficiency.
