Description
Technical Field
The utility model relates to a wheel puller, concretely relates to vehicle wheel puller suitable for trackless rubber-tyred car.
Background
In the coal mine production operation, various trackless rubber-tyred vehicles such as an explosion-proof command vehicle, an explosion-proof material vehicle, an explosion-proof man car and the like are frequently used, but the failure rate of tires is high due to poor flatness of the roadway surface of an underground roadway; the wheel bearing of the explosion-proof vehicle is easy to lock, so that the disassembly is difficult.
The conventional method for disassembling the tire is used at present, a jack is used for supporting a wheel, two operators are matched with each other to pry the tire from inside to outside by using a pry bar, and the condition that the tire is not inclined due to uniform stress of the pry bar in the disassembling process is ensured; sometimes, the bearing is seriously locked, and even the heavy hammer is required to apply force to remove the tire, so that the removal efficiency is lower during daily tire maintenance, and certain potential safety hazards also exist when a crow bar and the heavy hammer are used.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a vehicle wheel puller suitable for trackless rubber-tyred car to it is lower not only to solve the conventional method of dismantling the tire, also has the problem of certain potential safety hazard in addition.
In order to achieve the above object, the technical solution of the present invention is:
the utility model provides a vehicle wheel puller suitable for trackless rubber-tyred car which characterized in that: comprises a fixed plate, a lead screw and a pressing block;
the fixing plate is provided with a fixing hole; the fixing hole comprises at least three long holes, or at least two long holes and a round hole; the size and distribution of the fixing holes are matched with bolts for mounting the tire;
the fixed plate center be equipped with the screw hole of lead screw looks adaptation, the lead screw passes the screw hole, and the one end of lead screw is equipped with the detachable briquetting, as the position with vehicle steering spindle butt, and the other end of lead screw is equipped with the dop, as the torsional position of application of force.
Furthermore, the fixed plate is provided with three fixed holes, including two strip holes and a round hole, and is distributed in a triangular manner on the whole.
Further, one end of the long hole is provided with an opening.
Furthermore, the end of the pressing block is provided with a flexible block, and the flexible block is made of rubber.
Further, the briquetting passes through the bolt and realizes being connected with dismantling of lead screw.
Furthermore, the threaded hole is formed by welding a nut and a hole in the center of the fixing plate.
Further, the threaded hole is tapped by a hole in the center of the fixing plate.
Further, the dop is the setting of hexagonal square head.
The utility model has the advantages that:
1. the fixing plate is fixed on the wheel through the fixing hole, the wheel and the wheel hub are ejected out through displacement generated by rotating the lead screw, the wheel is uniformly stressed in the process and is ejected out of the steering shaft of the vehicle along the axial direction, and inconvenience caused by the fact that a prying bar is needed to keep the tire uniformly stressed at any time is avoided; compared with the conventional method for disassembling the tire, the wheel puller skillfully converts larger pulling force into smaller circumferential force, so that the tire can be disassembled by one person. The vehicle wheel puller not only improves the efficiency of tire dismounting, but also avoids the potential safety hazard caused by the use of crow bars and hammers.
2. The dop is the setting of hexagonal square head, and the operator of being convenient for uses spanner or wind big gun to twist the screw hole at fixed plate center with the lead screw.
3. The fixing holes on the fixing plate are arranged, so that the fixing plate can be directly fixed on the tire by using bolts arranged on the wheel hub.
4. The distribution of the strip holes is matched with bolts for mounting tires, and the bolts can move according to the positions of the strip holes when tires with different diameters are assembled, so that the fixing plate can be mounted on the tires with different sizes, and the corresponding wheel puller is prevented from being manufactured for each type of tire; when the tire is difficult to dismantle, can select the fixed plate that has four or five rectangular holes, avoided leading to the not enough problem of fixed plate intensity because of fixed plate thickness is limited and rectangular hole number is few.
5. The fixed orifices are distributed in a triangular shape on the whole, so that the shape of the fixed plate can be selected to be in a triangular shape, the area of the fixed plate is reduced while the fixed action of the fixed plate is ensured, and the portable fixed plate is convenient to carry.
6. The end of the pressing block is provided with a flexible block, the flexible block is made of rubber, and the pressing block can be prevented from damaging a steering shaft of the vehicle when the wheel puller is used.
