Abstract

A tie-rod type detacher capable of detaching water pump turbine impellers and tight accessories such as couplings, gears, bearings and belt pulleys of various large-sized equipment consists of a push device, an annular retainer disc, a tie rod, a semi-ring clamping block and a collar clamp. The push device consists of a pull disc, an oil cylinder, a rid plate, wheels and the like, the push device is positioned with the annular pull disc by utilizing the collar clamp to be engaged with the semi-ring clamping block and then is assembled with the tie rod to form a rigid structure, a detached water pump is hoisted in place, four raised square ribs on an outer casing of the middle segment of the water pump penetrate through four corresponding square slots at the inner bore of the annular retainer disc and rotate a certain angle, the oil cylinder is started to push a water pump shaft, and then the water pump impeller with relatively tight engagement is detached through relative motion of the outer casing of the water pump middle segment and the water pump shaft. The detacher has the advantages that the detacher has large detaching power capable of being up to 100 tons, is convenient for adjusting detaching distance, can set the effective working length of the rigid structure according to site requirements only by dismounting or mounting the semi-ring clamping block and the collar clamp, has wide applicable range and can not only detach wheel pairs but also bearings, gears and the like.

Description

The rod-pulling type stripping attachment

Affiliated technical field

The utility model relates to the rod-pulling type stripping attachment than interference fit such as a kind of detachable water pump water wheels, various main equipment shaft coupling, gear, bearing, belt pulley, can be widely used in water pump repair workshop and each large-scale, heavy-duty machinery repair shop of every profession and trade, all departments.

Background technology

At present, also more at various water pump water wheels, equipment to the disconnecting apparatus and disengaging gear of counterparts such as wheel, bearing, include screw type and pull out the hydraulic pressure that thick stick, hydraulic jack apply active force and pull out thick stick and various special equipment thereof, these training equipments when using for the dismounting resistance during at the water wheels below 30 tons, to wheel effect relatively good.The problem that exists is: 1. removal force is little.After the dismounting resistance of split counterpart reached more than 80 tons, the hydraulic pressure that applies active force pulls out thick stick and various special equipment thereof catching problem such as be out of shape, fracture will occur, and can't pull down counterpart.2. adaptability is not strong.Because the length of pulling out the thick stick catching is certain, when split counterpart is assemblied in apart from spindle nose than distant positions, catching just overlap not on, can't organize the water pump water wheels of middle part, gear etc. and dismantle being assemblied in axle.

Summary of the invention

Little and do not accommodate the deficiency of dismounting water pump water wheels for solving the existing class disconnecting apparatus and disengaging gear removal force of taking turns, the utility model provides a kind of rod-pulling type stripping attachment.This rod-pulling type stripping attachment can not only effectively pull down various be assemblied in spindle nose to wheel, bearing, and, can split out the water pump water wheels that are assemblied in axle group middle part, gear etc. easily than the tight fit member.

The technical scheme that its technical problem that solves the utility model adopts is: in dividing equally in the hole by pressing device that draws dish, jack, gusset and wheel etc. to constitute and corresponding annular block plate, five equilibrium is parallel is equipped with 3 or 6 fluted pull bars of processing, and cooperates the semi-ring fixture block that it is blocked by required distance by clip.Constitute one and can bear the braced frame of thrust more than hundred tons, when dismounting be positioned at spindle nose to wheel or during bearing, support plate is placed on annular block plate and by between the separation of copulating moth wheel, utilize the piston rod pushing of the thrust more than hundred tons that oil cylinder has to be disassembled spindle nose, both can cooperate resistance reach hundred tons wheel is pulled down.When dismounting is positioned at the water pump water wheels of an interlude, 4 projection side's muscle of water pump stage casing shell are passed 4 corresponding square groove retrotorsion one angles at annular block plate endoporus place, it is contacted with the end face of belt block plate, open oil pump, make oil cylinder promote pump shaft, to cooperate tighter water pump water wheels to pull down by the water pump stage casing, reach dismounting is positioned at the counterparts such as water pump water wheels of an interlude than tight fit member and dismounting purpose.

The beneficial effects of the utility model are, by drawing dish, jack, what the pressing device of formation such as gusset and wheel adopted is integral structure, corresponding making draws dish can bear very big pulling force, and the distance of the stressed offset pull bar of annular block plate is closer, correspondingly can bear very big thrust, the two matches with pull bar and semi-ring fixture block, just constituted a braced frame that can bear hundred tons of thrusts, powerful thrust in conjunction with jack just can be pulled down very tight shaft coupling of cooperation and bearing thereof etc. smoothly, in addition, owing to be assemblied in clip and semi-ring fixture block fast demountable in the pull bar groove, be convenient to the effective working distance of adjusting yoke, like this, just can dismantle the water pump water wheels or other structural member that are assemblied in a stage casing easily.
