Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic motor auxiliary tools, and more specifically, particularly belongs to a disassembly tool for a hydraulic motor of a bucket wheel stacker reclaimer. Background Art

[0002] The bucket wheel driving mechanism of the bucket wheel stacker reclaimer is driven by a hydraulic motor. If the hydraulic motor is used for a long time, it will leak oil, the internal part of the motor will wear out, and the motor leakage will increase and the speed will slow down. The motor needs to be disassembled, replaced and maintained.

[0003] Hydraulic motors often use spline connections. Because the spline part is close to the shaft end, the thickness of the hydraulic motor is more than 1 meter, and the depth of the spline and the optical axis is less than 0.5 meters. A set of positioning components with a diameter of Φ95*50mm is set at the oil port end, which is fixed on the bucket wheel shaft by an M30*500 high-strength screw to play the role of coaxial positioning and axial fixing. Therefore, when disassembling the hydraulic motor, you need to remove the fixing screws first, and then remove the positioning component. Because the positioning component and the inner hole of the cylinder body at the oil port end are tightly matched, and it is embedded in the cylinder body, the positioning component is difficult to remove. It can only be pulled and disassembled using the bolt hole in the middle of the positioning component that matches the fixing screw as the fulcrum. However, due to the tight fit, it is time-consuming and laborious to remove the positioning component, and the next step cannot be carried out without removing the component, which seriously affects the maintenance progress of the motor. Summary of the invention

[0004] The utility model aims to overcome the shortcomings of the above-mentioned traditional technology and provide a disassembly tool for the hydraulic motor of a bucket wheel stacker reclaimer, so as to facilitate the disassembly of the hydraulic motor positioning assembly.

[0005] The utility model provides a disassembly tool for a hydraulic motor of a bucket wheel stacker and reclaimer, comprising a pressure plate, a waist-shaped stud, a rotating nut and a disc; a semi-waist-shaped hole matching the cross-sectional shape of the waist-shaped stud is provided at the center of the pressure plate, the major diameter of the semi-waist-shaped hole is larger than the major diameter of the cross-sectional shape of the waist-shaped stud; the semi-waist-shaped hole is asymmetrically arranged at the center of the pressure plate; the waist-shaped stud passes through the pressure plate through the semi-waist-shaped hole; a disc is arranged at one end of the waist-shaped stud; a rotating nut is threadedly matched on the waist-shaped stud, and the rotating nut is located on a side of the pressure plate away from the disc.

[0006] The utility model provides a disassembly tool for the hydraulic motor of a bucket wheel stacker and reclaimer, which is designed with a pressure plate, a waist-shaped stud, a rotating nut and a disc; wherein the size of the disc is designed to match the size of the bolt hole in the middle of a positioning component; the pressure plate matches the waist-shaped stud through the semi-waist-shaped hole, and the waist-shaped stud matches the rotating nut; when disassembling the positioning component, one end of the disc is passed through the positioning component through the bolt hole in the middle of the positioning component, and then the waist-shaped stud is translated in the semi-waist-shaped hole to make the disc plane close to the inner wall of the positioning component, and then the rotating nut is rotated to push the pressure plate to move toward the end of the hydraulic motor until the pressure plate and the end of the hydraulic motor fit together, and finally the rotating nut is rotated to move toward the pressure plate. Due to the shape limitation of the semi-waist-shaped hole, the waist-shaped stud cannot rotate in the semi-waist-shaped hole and can only move in parallel. Therefore, under the drive of the rotating nut, the waist-shaped stud moves outward of the hydraulic motor, the waist-shaped stud drives the disc to move, and the disc drives the positioning component to move outward of the hydraulic motor, so that the disassembly of the positioning component can be achieved.

[0007] It can be seen that, compared with the prior art, the utility model is simple to operate and has high disassembly efficiency, and can conveniently and quickly disassemble the positioning assembly on the hydraulic motor. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0015] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0016] The utility model provides a disassembly tool for a hydraulic motor of a bucket wheel stacker reclaimer, comprising a pressure plate 1, a waist-shaped stud 2, a rotating nut 3 and a disc 4. A semi-waist-shaped hole 101 matching the cross-sectional shape of the waist-shaped stud 2 is provided at the center of the pressure plate 1, and the long diameter of the semi-waist-shaped hole 101 is larger than the long diameter of the cross-sectional shape of the waist-shaped stud 2; the semi-waist-shaped hole 101 is asymmetrically arranged at the center of the pressure plate 1. The waist-shaped stud 2 passes through the pressure plate 1 through the semi-waist-shaped hole 101. A disc 4 is provided at one end of the waist-shaped stud 2, and the diameter of the disc 4 matches the diameter of the bolt hole for installing the fixing screw in the middle of the positioning assembly 5. The waist-shaped stud 2 is threadedly matched with a rotating nut 3, and the rotating nut 3 is located on the side of the pressure plate 1 away from the disc 4.

[0017] The specific usage and function of this embodiment are as follows:

[0018] When disassembling the hydraulic motor 6, first remove the fixing screws, then pass the disc 4 and the waist-shaped stud 2 of the utility model through the bolt hole in the middle of the positioning assembly 5 and pass through the positioning assembly 5; then operate the waist-shaped stud 2 to move horizontally in the semi-waist-shaped hole 101, and make the disc 4 passing through the positioning assembly 5 close to the inner wall of the positioning assembly 5; then rotate the rotating nut 3 to push the pressure plate 1 to move toward the end of the hydraulic motor 6 until the pressure plate 1 and the ends of the hydraulic motor 6 are fitted together; finally, rotate the rotating nut 3 to move in the direction of the pressure plate 1. Due to the shape limitation of the semi-waist-shaped hole 101, the waist-shaped stud 2 cannot rotate in the semi-waist-shaped hole 101 and can only move in parallel. Therefore, driven by the rotating nut 3, the waist-shaped stud 2 moves outside the hydraulic motor 6, the waist-shaped stud 2 drives the disc 4 to move, and the disc 4 drives the positioning assembly 5 to move outside the hydraulic motor 6. In this way, the positioning assembly 5 can be disassembled.

[0019] In summary, the utility model is easy to operate and can conveniently and quickly remove the positioning assembly on the hydraulic motor compared to the prior art, which greatly shortens the disassembly time of the positioning assembly and shortens the motor disassembly and replacement cycle.
