Abstract
The utility model discloses a round pin axle rises tightly to overlap and demolishs specialized tool, including the tight cover that rises, the flange through bolted connection on the outer terminal surface of the tight cover that rises, the flange center has the screw, and the flange outside is setting up one and is supporting the cover, supports the cover outside and is setting up a cavity hydraulic jack, has worn a rhizoid pole in the centre bore of jack, and lead screw outside end is setting up the end nut, and the medial extremity of lead screw passes and supports the cover and pass through the screw with the flange and link to each other, and high -pressure oil pump in the business turn over liquid jogged joint of jack. The utility model discloses can conveniently dismantle the round pin axle tight cover that rises, improve the operating efficiency, use manpower sparingly.
Description
Technical field
The utility model relates to a kind of bearing pin expansion sleeve and removes specific purpose tool.
Background technology
The bearing pin of band expansion sleeve form during equipment of hot rolling maintenance, the dismounting of expansion sleeve uses jackscrew, or uses hammer chisel to knock.Equipment of hot rolling is under hot and humid environment, and corrosion is serious, and dismounting difficulty is large.Apparatus arrangement closeness is high, and working space is narrow and small, and use hammer to brandish apart from little, operating personnel easily collides with.Iron oxide powder is many, easily enters in expansion sleeve gap and causes expansion sleeve to be difficult to remove.Jackscrew is used to remove because a lot of tensioning sleeve of corrosion is not torn open not get off.
Summary of the invention
The purpose of this utility model is to provide a kind of bearing pin expansion sleeve to remove specific purpose tool, can dismantle bearing pin expansion sleeve easily, improve operating efficiency, save manpower.
The purpose of this utility model realizes like this, a kind of bearing pin expansion sleeve removes specific purpose tool, comprise expansion sleeve, the outer face of expansion sleeve is bolted flange, flange center has screw, flange outer setting a support set, support set arranged outside a hollow hydraulic jack, a rhizoid bar is installed with in the centre bore of jack, screw mandrel outboard end arranges end nut, the medial extremity of screw mandrel is connected by screw with flange through support set, and the liquid inlet/outlet of jack is connected to high-pressure oil pump.
When needs dismounting expansion sleeve, first by expansion sleeve disassembling bolts, flange is fixed by bolts on expansion sleeve end face, screw mandrel is tightened in the screw in the middle part of drawing flange; Support set is inserted in from screw mandrel head and puts in place; After hollow hydraulic jack is inserted in screw mandrel, use side head nut compresses hollow hydraulic jack.Connect high-pressure oil pump, suppress jack, support set is withstood in jack emersion, pull-out screw mandrel and expansion sleeve.The utility model can dismantle bearing pin expansion sleeve easily, improves operating efficiency, saves manpower.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is main TV structure schematic diagram of the present utility model.
Detailed description of the invention
A kind of bearing pin expansion sleeve removes specific purpose tool, as shown in Figure 1, comprise bearing pin 7, expansion sleeve 1, the outer face of expansion sleeve 1 is connected to flange 2 by bolt 8, flange 2 center has screw, flange 2 outer setting a support set 3, support set 3 arranged outside a hollow hydraulic jack 4, a rhizoid bar 5 is installed with in the centre bore of jack 4, screw mandrel 5 outboard end arranges end nut 6, the medial extremity of screw mandrel 5 is connected by screw with flange 2 through support set 3, and the liquid inlet/outlet of jack 4 is connected to high-pressure oil pump.
