Abstract
The utility model provides a device is pulled out on belt pulley top, pull out disc, the hot candied pole in top and " T " type hook including rotatory gasket, top, the even interval of circumference that " T " type hook pulled out the disc along the top sets up, pushes up the center screw hole looks spiro union that hot candied pole and top pulls out the disc, and rotatory gasket is equipped with the bellied massive structure of toper for the top center is equipped with tapered groove bottom center, and tapered groove matches bottom the toper of pushing up hot candied pole and puts. The utility model discloses simple structure, convenient to use has improved round efficiency of pulling out of big belt pulley.
Description
Technical field
The utility model belongs to the technical field of pulley extractor, is related to a kind of belt pulley and pulls device.
Background technology
The belt pulley pulling device for using at present, generally forges Three-claw pull-horse and hydraulic wheel puller.Their three hooks
To axle center, hook must be ridden in the outer rim of wheel, therefore is not applied for the belt pulley of large-size.In real work,
Maintenance personal is used cooperatively using homemade fixture and with screw jack, and also useful flame heating wheel hub is outwards struck again with hammer
The method for ejecting belt pulley with jackscrew is beaten, but effect is bad, and maintenance difficulty is big.
The content of the invention
The technical problems to be solved in the utility model is to propose that a kind of belt pulley pulls device, is applicable to large-scale belt pulley
Wheel operation is pulled out, maintenance load is reduced, operating efficiency is lifted.
The utility model solves the technical scheme that its technical problem adopted：A kind of belt pulley pulls device, its feature
It is：Including rotation pad, pull disk, pull screw mandrel and T-shape hook, the T-shape hook is along the disk that pulls
Circumferential uniform intervals are arranged, the center screw bolt for pulling screw mandrel and pulling disk, and the rotation pad is in top
The heart is provided with the block structure that conical socket bottom centre is provided with tapered protrusion, the conical socket and the conical lower portion for pulling screw mandrel
Phase configuration.
By above-mentioned technical proposal, the T-shape hook is made up of screw rod and cross bar, in the screw rod bottom and the cross bar
The heart is connected, and screw tip is connected through the connecting hole for pulling disk and by nut positioning.
The beneficial effects of the utility model are：Propose that a kind of belt pulley pulls device, improve it is traditional pull out wheel mode,
T-shape hook can ride over the centre of wheel hub spoke and use, it is not necessary to be fixed in the outer rim of belt pulley so that pull strength and be more easy to
Concentrate, pull out wheel effect more preferably, the problem that effectively solving plunger displacement pump big belt pulley is not drawn out easily, it is ensured that the maintenance of equipment,
The workload of maintenance personal is reduced, operating efficiency is lifted.
Description of the drawings
Fig. 1 is the structural representation of one embodiment of the present utility model.
Wherein：Rotation pad 1, pulls disk 2, pulls screw mandrel 3, conical socket 4, tapered protrusion 5, screw rod 6, cross bar 7, spiral shell
Female 8.
Specific embodiment
To more fully understand the utility model, the utility model is further retouched with reference to the accompanying drawings and examples
State.
As shown in figure 1, a kind of belt pulley pulls device, including pad 1 is rotated, disk 2 is pulled, is pulled screw mandrel 3 and T-shape
Hook, T-shape hook arranges 3 along the circumferential uniform intervals for pulling disk, pulls screw mandrel and pulls the center screw phase of disk
It is spirally connected, rotation pad is provided with the block structure that the bottom centre of conical socket 4 is provided with tapered protrusion 5, conical socket for top center
With the conical lower portion phase configuration for pulling screw mandrel.
T-shape hook is made up of screw rod 6 and cross bar 7, and screw rod bottom is connected with cross bar center, and screw tip is passed through and pulls circle
The connecting hole of disk is simultaneously connected by the positioning of nut 8, and T-shape hook can be with 360 ° of rotations and arbitrarily dismounting, adjustment, and it can ride over
The centre of wheel hub spoke uses, without in the outer rim going to ride over belt pulley as traditional operation.
When carrying out pulling out wheel using this device：The screw rod of three T-shape hooks is each passed through three connecting holes for pulling disk,
It is located by connecting using nut, while the cross bar for making three T-shape hooks all rides over the centre of belt wheel spoke, rotation pulls disk
Middle pulls screw mandrel, and lays a rotation pad in the conical lower portion for pulling screw mandrel, makes its tapered protrusion be directed at belt
The axle center of wheel, plays a part of righting, centering and protection and pulls screw mandrel to reduce friction resistance, continues rotation and pulls screw mandrel, treats three
After individual T-shape hook is all adjacent to belt wheel spoke, reexamine, adjust the riding position of three T-shape hooks, make belt pulley,
Rotation pad with the axle center for pulling screw mandrel point-blank, finally pulls screw mandrel with wrench or pipe wrench rotation, makes to pull disk
Along screw mandrel reach is pulled, belt pulley is pulled out.
Claims (2)
1. a kind of belt pulley pulls device, it is characterised in that：Including rotation pad, pull disk, pull screw mandrel and T-shape hook
Pawl, the T-shape hook is arranged along the circumferential uniform intervals for pulling disk, the center for pulling screw mandrel and pulling disk
Screw bolt, the rotation pad is provided with the block structure that conical socket bottom centre is provided with tapered protrusion for top center,
