Abstract
The utility model discloses a wire-unrolling tackle wheel puller which comprises a disk which is provided with a central through hole and at least three pulling claws with inward hood heads, and the pulling claws are evenly distributed on the disk. Pulling rods of the pulling claws pass through the disk and are arranged on the circumference of the disk through pin shafts which are inserted in the pulling rods, and a lead screw is arranged in the central through hole of the disk in a threaded matching mode. The wire-unrolling tackle wheel puller is capable of effectively reducing damage to pulleys, and guaranteeing that a wire-unrolling tackle can be used normally after being assembled.
Description
Technical field
The utility model relates to field of power, particularly a kind of pulley extractor be used to dismantling large-scale releasing pulley.
Background technology
The power system application is very extensive, the every aspect that relates to people's life, the construction of the transmission line of electricity various places that spread all over the country, because the difference of the aspects such as area, landform, traffic, custom, make the technique of Poling Construction have very large difference, each unit in charge of construction is bound to adopt different stringing construction methods according to the condition of the characteristics of separately construction and existing equipment.Generally to adopt wire gauge be the LGJ-900/75 large-section lead to extra high voltage line in the power system, and employed releasing pulley is nine to take turns coaster.Coaster diameter 1.3m, heavy 630kg, can't whole Transporting to the mountain, after needing will supratrochlear large-scale drive to dismantle, be transported on the mountain and assemble again.The old way of dismounting releasing pulley is knocked with sledgehammer exactly at present, wastes time and energy, and is easy to make the wheel sheet impaired in unloading process, causes damage.
The utility model content
It is time saving and energy saving that technical problem to be solved in the utility model provides a kind of operation, avoids the releasing pulley pulley extractor of the damage that in the unloading process coaster caused.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
The releasing pulley pulley extractor, comprise that the disk that is provided with central through hole and even cloth are at least three inside pulling claws of disk upper hookhead, the pull bar of described pulling claw passes disk and is arranged on the periphery of disk by the bearing pin that is through on the pull bar, and threaded engagement has leading screw in the central through hole of disk.
Improvement of the present utility model is: be provided with the adjustment hole that several are used for regulating pulling claw eave tile and disk distance on the pull bar of described pulling claw.
Improvement of the present utility model also is: the top of described leading screw is provided with the handle that rotates for auxiliary leading screw.
Improvement of the present utility model also is: described disk below arranges a nut that is connected with threads of lead screw.
Because the technological progress of having adopted technique scheme, the utility model to obtain is:
The utility model provides a kind of pulley extractor, is used for substituting knocking the mode of dismantling large-scale wheel disc with sledgehammer at present, can effectively reduce the damage to pulley, guarantees can normally use after the releasing pulley assembling is finished.The utility model is equally applicable to dismantle the Wheel-type parts of other specifications and size.
The utility model catches on wheel conveniently to pull out wheel with the eave tile on the pulling claw, and pulling claw is arranged on by bearing pin on the periphery of disk, and the time spent can not extract bearing pin, can easily finish the dismounting of pulley extractor.The convenient distance according to wheel sheet and bearing of the adjustment hole that arranges on the pull bar of pulling claw is come the distance of pulling claw eave tile and disk, to have adapted to the wheel disc that pulls out different model.The auxiliary leading screw that is used for that the leading screw top arranges rotates.The disk below arranges a nut, and nut is connected with threads of lead screw, rotates the drive leading screw by handle and moves in nut.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein: 1. disk, 2. leading screw, 3. pulling claw, 4. nut, 5. adjustment hole, 6. bearing pin, 7. handle, 8. eave tile.
The specific embodiment
With specific embodiment the utility model is described in further details by reference to the accompanying drawings:
A kind of releasing pulley pulley extractor comprises pulling claw 3, leading screw 2 and disk 1 as shown in Figure 1.
The center of disk 1 is provided with centre bore, annular even three installing holes that are furnished with on the card of disk.Disk 1 below arranges a nut that is connected with threads of lead screw 4.
Leading screw 2 passes the centre bore of disk, and with the centre bore threaded engagement, the top of leading screw 2 is provided with the handle 7 that rotates for auxiliary leading screw 2.
Be provided with three adjustment holes 5 on the pull bar of every pulling claw 3, adjustment hole 5 is used for regulating pulling claw eave tile 8 and disk 1 distance, after installing hole is passed on the top of pulling claw 3, passes the adjustment hole of pulling claw by bearing pin 6, with the pulling claw movable hanging on the upper surface of disk 1.Pulling claw 3 bottoms are provided with eave tile 8, are used for hooking being operated part.
When the utility model is used for the dismounting releasing pulley, the eave tile 8 of pulley extractor pulling claw 3 is caught on nine lower surfaces of taking turns coaster monolithic wheel, live nine with the leading screw 2 lower end crowns and take turns coaster middle part bearing, the handle 7 by auxiliary leading screw 2 rotations reverses, rely on the strength of leading screw 2, pulley sheet is withdrawed from.When using pulley extractor, can also at nut 4 place's apply oils, guarantee to be in normal operating conditions between pulley extractor adjusting screw 2 and the nut 4.
When the releasing pulley pulley extractor does not use, pulling claw 3 is disassembled from disk 1, offer convenience for work and transportation.
