Abstract
The utility model relates to a maintenance device is dismantled to the wheel, specifically is a heavy wheel puller with adjustable. The technical problem that the existing wheel puller cannot be suitable for coupling wheels with different outer diameters is solved. An adjustable heavy duty wheel puller comprises a U-shaped bracket with a horizontal opening, wherein a hydraulic jack is horizontally arranged in the bracket; the top and bottom open ends of the bracket are respectively and horizontally connected with an upper mounting plate and a lower mounting plate which are vertical to the plane of the bracket; the height of the first adjusting plate is larger than the distance between the upper mounting plate and the lower mounting plate; one side of the adjusting plate protrudes outwards to form a limiting block with the height being the same as the distance between the upper mounting plate and the lower mounting plate. After transformation, one wheel puller replaces all the pullers, and decompression is carried out on the storage space of the storehouse; the field maintenance does not need to consider the size of the wheel puller of the equipment, and the phenomenon that the wheel puller is taken wrongly is avoided.
Description
Technical Field
The utility model relates to a maintenance device is dismantled to the wheel, specifically is a heavy wheel puller with adjustable.
Background
Coal preparation plant's use equipment is many, and the connected mode adopts the wheel pair to connect more, dismantles in the maintenance of equipment, and the difficulty is dismantled to the wheel pair, and the approximate 50% that accounts for whole maintenance time, the wheel pair of all kinds of equipment is not of uniform size moreover, and required wheel puller also differs, and is required in order to satisfy equipment, leads to pulling out the wheel ware numerous, and storehouse occupation space is big.
In order to unify the use of the wheel puller, improve the wheel pulling efficiency and reduce the cost, it is very necessary to design a wheel pulling device suitable for the pair wheels with different diameters.
Disclosure of Invention
The utility model discloses a solve present wheel puller and can not be applicable to the technical problem of different external diameter coupling wheels, provide a heavy wheel puller with adjustable.
The utility model discloses an adopt following technical scheme to realize: an adjustable heavy duty wheel puller comprises a U-shaped bracket with a horizontal opening, wherein a hydraulic jack is horizontally arranged in the bracket; the top and bottom open ends of the bracket are respectively and horizontally connected with an upper mounting plate and a lower mounting plate which are vertical to the plane of the bracket; the height of the first adjusting plate is larger than the distance between the upper mounting plate and the lower mounting plate; one side of the adjusting plate protrudes outwards to form a limiting block with the height being the same as the distance between the upper mounting plate and the lower mounting plate.
When the utility model is used, the whole device can be placed and fixed on a trolley, the pair wheel is arranged in the bracket, and then the distance between the two adjusting plates is adjusted from the left direction and the right direction of the pair wheel close to the equipment side, so as to adapt to the pulling-out operation of the pair wheels with different outer diameters; the limiting block of the adjusting plate is just clamped between the upper mounting plate and the lower mounting plate to realize limiting; two regulating plates are clamped on the surface of one side of the wheel equipment, the ejector rod of the regulating hydraulic cylinder abuts against the shaft of the equipment (the shaft penetrates through the center of the wheel), the regulating plates are tightly abutted and tightly clamped on the surface of one side of the wheel equipment, the ejector rod of the operating hydraulic cylinder extends outwards at the moment, the ejector rod acts on the shaft of the equipment, the equipment and the shaft are integrally immobile, the ejector rod drives the whole wheel puller and the trolley to backwards move through the two regulating plates in the outwards ejecting process, the wheel is pulled out from the shaft, and wheel pulling operation is completed.
Furthermore, universal wheels are installed at the bottom of the support, and the whole device can be directly used for pulling out the coupled wheels without additionally using a trolley.
The utility model has the advantages that: 1. after transformation, one wheel puller (puller) replaces all the pullers, and decompression is carried out on the storage space of the storehouse.
2. After transformation, field maintenance is carried out, the size of the wheel puller of the equipment is not needed to be considered, and the phenomenon that the wheel puller is taken wrongly is avoided.

Detailed Description
As shown in fig. 1, an adjustable heavy duty wheel extractor comprises a bracket with a U-shaped opening and a horizontal opening, wherein a hydraulic jack 7 is horizontally arranged in the bracket; the top and bottom open ends of the bracket are respectively and horizontally connected with an upper mounting plate 1 and a lower mounting plate 2 which are vertical to the plane of the bracket; the height of the first adjusting plate 3 is larger than the distance between the upper mounting plate and the lower mounting plate, and the second adjusting plate 4 is arranged on the upper mounting plate; one side of the adjusting plate protrudes outwards to form a limiting block 5 with the height same as the distance between the upper mounting plate and the lower mounting plate. The middle parts of the upper and lower mounting plates are respectively mounted at the top and the bottom of the bracket.
The two adjusting plates play a role in the traditional puller claw in the past, are convenient for size adjustment and can adapt to the pulling-out operation of the pair wheels with different outer diameters.
The thickness of the adjusting plate and the limiting block is 50 mm.
As shown in fig. 1, a hoisting and transporting ring is fixed at the top of the bracket; the support is formed by welding I-beams.
As shown in fig. 2, the top rod of the hydraulic jack supports against the shaft of the equipment from left to right, and the pair of adjusting plates cling to the right side surfaces of the pair of wheels (the upper and lower parts of the adjusting plates are clamped on the left side of the mounting plate); the jack rod of the hydraulic jack extends rightwards to jack the shaft, and the jack drives the paired wheel and the whole wheel puller to move leftwards through the mounting plate and the adjusting plate to pull out the paired wheel because the shaft and the equipment are kept still.
Universal wheels are arranged at the bottom of the bracket and on the lower mounting plate; the hoisting and transporting ring is convenient for hoisting and transporting a travelling crane, the universal wheels are convenient for moving on the ground quickly and flexibly, and the wheel pulling operation is completed by matching with the motion of the wheel puller. The longitudinal section of the adjusting plate is in a convex shape, and the protruding part is used for limiting the adjusting plate.
