Description

Technical Field

[0001] The invention belongs to the technical field of disassembly tooling, and in particular relates to a disassembly device for a reducer. Background Art

[0002] In industrial production, reducers are key transmission equipment, and their maintenance and inspection are particularly important.

[0017] The disassembly device for the reducer provided by the present invention realizes the safety, efficiency and convenience of the reducer disassembly operation through the coordinated cooperation of the supporting components and the disassembly components; among them, the adjustable bracket 6 of the supporting component and the adjustable connection with the column 4, the horizontal adjustment of the adjustable plate 14 and the distance adjustment of the front / rear vertical plates 9 can flexibly adapt to the disassembly requirements of different types of reducers; the rigid clamping structure formed by the front vertical plate 8 and the rear vertical plate 9 through the stud bolts 10, combined with the bottom support of the pressure block 15, constitutes a stable force system, which effectively prevents the reducer from tilting or falling during the disassembly process; the design of the hydraulic puller 12 directly acting on the driven shaft, combined with the movable characteristics of the caster group, realizes the continuous disassembly action of "pushing-moving", which greatly improves the working efficiency; at the same time, the precise fit adjustment of the adjustable plate 14 and the bottom surface of the reducer provides a reliable alignment reference for subsequent installation and resetting, solving the technical problems of traditional reducer disassembly methods such as high labor intensity, many safety hazards and low work efficiency.

[0018] In a specific embodiment, horizontal adjustment holes and vertical height adjustment holes are respectively provided on the column 4 of the support component and the adjustable bracket 6, which can adapt to the disassembly of reducers of different models and different elevation positions. The adjusting bolts 13 on the support component can accurately control the height and horizontal inclination of the adjustable plate 14, so that the adjustable plate 14 is completely in contact with the bottom surface of the reducer to be removed. When the hydraulic puller 12 ejects the reducer, the bottom casters can drive the entire device and the reducer to be removed to gradually separate from the driven shaft, and the disassembly process is very smooth. At the same time, it can facilitate accurate alignment during installation and resetting operations. When the entire device is in operation, the pressure blocks 15 composed of shims of different thicknesses support the adjustable plate 14 and the bottom surface of the reducer to be removed. The front vertical plate 8 and the rear vertical plate 9 are connected and fixed to the side of the reducer to be removed, and are connected to the support plate 3 through the adjustable bracket 6 and the column 4, so that the disassembly and subsequent relocation process are safe and stable, preventing the reducer from falling and injuring people, ensuring the personal equipment safety and work quality of disassembling this type of reducer, and at the same time reducing the labor intensity of the operators and improving work efficiency.

[0020] The adjustable bracket 6 adopts a T-shaped structure, with a sliding hole on one side of the front vertical plate 8 and a round hole on one side of the rear vertical plate 9. It is connected to the threaded holes on the sides of the front vertical plate 8 and the rear vertical plate 9 through a second fastener 7, so that the front and rear positions of the front vertical plate 8 can be adjusted, and the distance between the front vertical plate 8 and the rear vertical plate 9 can be changed to adapt to different models and sizes of the reducer to be disassembled.

A circular hole is provided in the middle position of the front vertical plate 8 to allow the hydraulic rod of the hydraulic puller 12 to extend and pass through the circular hole to the end face of the driven shaft. With the center of the circular hole as the base point, 12 threaded holes are evenly distributed to install the hydraulic puller 12 through the connecting bolts 11, which can realize multi-angle installation of multiple types of pullers. The double-headed stud holes at the four corner positions of the front vertical plate 8 are horizontal long holes, which are used to fine-tune the horizontal position of the front vertical plate 8 and the rear vertical plate 9.

[0022] The rear vertical plate 9 is vertically mounted on the adjustable bracket 6 and fits in with the rear end face of the reducer to be disassembled. An open long hole is provided in the middle position of the rear vertical plate 9 to facilitate the radial passage of the rear vertical plate 9 through the driven shaft into the correct position. The stud holes at the four corner positions of the rear vertical plate 9 are vertical long holes, which are used to fine-tune the vertical position of the front vertical plate 8 and the rear vertical plate 9.

[0023] The studs connect the front vertical plate 8 and the rear vertical plate 9 to the reducer to be disassembled. The long holes of the front vertical plate 8 and the rear vertical plate 9 can realize micro-adjustment of the hydraulic puller 12 in the horizontal and vertical directions.

[0024] The support plate 3 on the support component is provided with a threaded hole, which is connected to the adjustment bolt 13. The adjustable plate 14 is provided with adjustment nuts on the upper and lower sides to achieve arbitrary adjustment of the position of the adjustable plate 14 in a large range in the horizontal direction.

[0025] Two universal casters 1 are provided at the front end of the bottom of the support plate 3 on the support component (on the side of the front vertical plate 8), and two fixed casters 2 are provided at the rear end (on the side of the rear vertical plate 9).

[0026] When in use, measure the elevation of the reducer to be disassembled, adjust the height of the adjustable plate 14 and the adjustable bracket 6, move the device to the position below the reducer to be disassembled, and fix the rear vertical plate 9 to the adjustable bracket 6 with bolts. The front vertical plate 8 and the rear vertical plate 9 are connected to the reducer to be disassembled with stud bolts 10. The front vertical plate 8 and the adjustable bracket 6 are fixed with bolts. The hydraulic puller 12 is fixed to the front vertical plate 8 with connecting bolts 11. By adjusting the bolts 13, the adjustable plate 14 is completely fitted with the bottom surface of the reducer to be disassembled, the pressure block 15 is placed, and the hydraulic puller 12 is operated to separate the reducer to be disassembled from the driven shaft. Only one person is required to operate, and the other person assists and monitors to complete the disassembly operation, which ensures safety and improves disassembly efficiency.

[0027] The disassembly device for the reducer provided by the present invention is provided with long holes in the horizontal and vertical directions on the supporting component, which can adapt to the disassembly work of reducers of different models and different positions. The adjusting bolts 13 on the supporting component can accurately control the height and horizontal inclination of the adjustable plate 14, so that the adjustable plate 14 is completely fitted with the bottom surface of the reducer to be disassembled. When the hydraulic puller 12 is pushed out, the bottom casters drive the entire device and the reducer to be disassembled to gradually separate from the driven shaft. The disassembly process is very smooth and can also facilitate accurate alignment during installation and resetting operations. When the entire device is in operation, the pressure-bearing fastener supports the bottom surface of the reducer to be disassembled, and the front and rear vertical plates 9 are connected and fixed to the sides of the reducer to be disassembled, and are connected to the support plate 3 through the adjustable bracket 6 and the column 4, which ensures the safety and quality of disassembling this type of reducer, while reducing labor intensity and improving work efficiency. It is especially suitable for reducers with output hole types and no disassembly internal threads.
