Description

Universal wheel puller

Technical Field

The utility model discloses a universal wheel puller, and belongs to the technical field of universal wheel pullers.

Background

When equipment is maintained, parts such as a bearing, a gear, a rotor and the like are required to be temporarily detached; when the bearing, gear, rotor, etc. are damaged, it is more necessary to remove the damaged parts. The safe and quick disassembly method can accelerate the maintenance progress and improve the maintenance efficiency. At present, the parts are frequently detached by a knocking method, knocking force is generally applied to an inner ring of a mechanical part, and the method is simple and easy to implement, but is easy to damage the parts. If the bearing, gear, rotor, etc. are removed and then reused, then the removal by destruction is never allowed. The utility model provides a universal wheel puller, aiming at solving the problem of time and labor waste in disassembly.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects in the prior art, the utility model aims to solve the technical problems that: provides an improvement of a structure of a universal wheel puller.

In order to solve the technical problems, the utility model adopts the technical scheme that: a universal wheel puller comprises two adjusting beams, a clamping wheel assembly and a fastening screw, wherein the adjusting beams are arranged in parallel, a nut is fixed between the two adjusting beams, a screw rod is screwed on the nut, and the fastening screw is welded at the upper end of the screw rod;

wherein press from both sides the wheel subassembly and include the relative U template of opening that the symmetry set up, every U template is formed by diaphragm, vertical edition and wheel splint welding, and wherein the upper end of diaphragm is fixed with two perforation, and each is adjusted the crossbeam and is passed through perforation swing joint on two diaphragms respectively and press from both sides the wheel subassembly.

The outer side of the wheel clamping plate is provided with a semicircular hook claw, and the component to be disassembled is clamped through the two symmetrical hook claws.

The nut is fixedly connected between the two adjusting cross beams in a welding mode.

Compared with the prior art, the utility model has the beneficial effects that: the universal wheel puller provided by the utility model is simple to manufacture and low in cost; the portable bearing box is convenient to carry and simple to operate, can be used for disassembling bearings, gears, rotors and other parts of various types, and is large in disassembling range and wide in application scene; compared with the traditional knocking method, the working efficiency is improved, time and labor are saved, and the safety risk is reduced.

Drawings

The utility model is further described below with reference to the accompanying drawings:

FIG. 1 is a front view of the present invention;

FIG. 2 is a side view of the present invention;

FIG. 3 is a top view of the present invention;

in the figure: 1 is an adjusting beam, 2 is a clamping wheel assembly, 3 is a fastening screw, 4 is a nut, 5 is a screw rod, 21 is a transverse plate, 22 is a vertical plate, 23 is a clamping wheel plate, 24 is a through hole, and 25 is a claw.

Detailed Description

As shown in fig. 1 to 3, the universal wheel extractor of the utility model comprises two adjusting beams 1 arranged in parallel, a clamping wheel assembly 2 and a fastening screw 3, wherein a nut 4 is fixed between the two adjusting beams 1, a screw rod 5 is screwed on the nut 4, and the fastening screw 3 is welded at the upper end of the screw rod;

wherein press from both sides the U template that the opening is relative that wheel assembly 2 set up including the symmetry, every U template is formed by diaphragm 21, vertical edition 22 and wheel splint 23 welding, and wherein the upper end of diaphragm 21 is fixed with two perforation 24, and each is adjusted crossbeam 1 and is passed through perforation 24 swing joint on two diaphragms 21 respectively on pressing from both sides wheel assembly 2.

The outer side of the wheel clamping plate 23 is provided with a semicircular hook claw 25, and the component to be disassembled is clamped through the two symmetrical hook claws 25.

The nut 4 is fixedly connected between the two adjusting cross beams 1 in a welding mode.

The working principle of the utility model is as follows: the hook claw 25 is used for sliding adjustment along the adjusting beam 1 to grasp various size parts, the detachable parts such as the bearing, the gear, the rotor and the like are sleeved by the hook claw 25, the screw rod 5 is enabled to prop against the axis, the fastening screw 3 is rotated by a wrench, the hook claw 25 drives the parts such as the bearing, the gear, the rotor and the like to move outwards, and the parts such as the bearing, the gear, the rotor and the like can be detached easily.

After the utility model is put into use, the time and the labor are saved; the original dismounting method wastes time and labor, wastes manpower, and takes 2 persons for dismounting 1 bearing, and the time is about 2 hours. The use of the universal wheel extractor for dismantling only needs 1 person, and the time is about 6 minutes. The bearing, the gear and the rotor are required to be dismounted by 100 in a whole mine every month, and a maintainer carries out manual calculation by 32 yuan per hour, so that the benefits brought by labor hour are saved: Δ S = (G0-G1) × C × D-R = (4-0.1) × 100 × 12 × 32-300 (cost) ≈ 14.9 (ten thousand yuan).

It should be noted that, regarding the specific structure of the present invention, the connection relationship between the modules adopted in the present invention is determined and can be realized, except for the specific description in the embodiment, the specific connection relationship can bring the corresponding technical effect, and the technical problem proposed by the present invention is solved on the premise of not depending on the execution of the corresponding software program.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the utility model has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
