Description

Technical Field

[0001] This utility model relates to the field of mining equipment disassembly and assembly technology, specifically to a disassembly and assembly machine lifting mechanism. Background Technology

[0002] In the maintenance and repair of hydraulic equipment, hydraulic cylinder disassembly and assembly machines play a crucial role. Their clamping components, as key parts, directly affect the efficiency and safety of the disassembly and assembly work. Existing hydraulic cylinder disassembly and assembly machines mostly employ a two-section structure with upper and lower sections, fixing the hydraulic cylinder by clamping it in the middle. To accommodate hydraulic cylinders of different lengths, they are typically designed with a movable structure that can move up and down.

[0003] Currently, this movable structure is mainly driven by multiple telescopic cylinders for vertical movement. While this method enables the clamping assembly to move up and down, it has significant drawbacks. Firstly, using two telescopic cylinders undoubtedly increases manufacturing costs and space requirements, resulting in a complex and bulky structure. Secondly, coordinating the control of multiple telescopic cylinders is challenging, requiring a more complex control system and precise adjustments. This not only increases maintenance costs but may also affect the clamping assembly's compatibility with hydraulic cylinders of different lengths due to insufficient control precision, reducing the equipment's practicality and efficiency. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model provides a lifting mechanism for a disassembly and assembly machine.

[0005] The technical solution of this utility model is as follows:

[0006] A lifting mechanism for a disassembly and assembly machine includes multiple columns, with a first clamping assembly fixedly mounted on the upper end of each column, and a second clamping assembly capable of vertical movement disposed between the multiple columns.

[0007] The bottom of each column is equipped with a base plate, and the base plate is equipped with a telescopic cylinder, the output end of which can move in the horizontal direction.

[0008] A fixing plate is provided on the bottom edge opposite to the output end of the telescopic cylinder, and multiple steel wire ropes are fixed at the fixing plate. The multiple steel wire ropes pass around the pulley assembly and extend along the column to the upper end of the second clamping assembly and are fixed. The output end of the telescopic cylinder is fixed to the pulley assembly, which can drive the steel wire ropes to move.

[0009] The pulley assembly is specifically designed as follows: the pulley assembly includes a movable pulley group and a stationary pulley group, and the movable pulley group is fixed to the output end of the telescopic cylinder. The stationary pulley group is fixed to the base plate, the column and the first clamping assembly, and the wire rope passes through the movable pulley group and the stationary pulley group in sequence and is fixed to the second clamping assembly.

[0010] The specific design of the movable pulley block is that the movable pulley block includes a U-shaped plate with its opening facing the fixed plate, and the U-shaped plate is fixed to the output end of the telescopic cylinder;

[0011] The steel wire rope is provided with four ropes, and two first double pulleys are installed inside the U-shaped plate. The four steel wire ropes are respectively arranged to pass around the two first double pulleys.

[0012] The static pulley assembly is specifically designed as follows: the static pulley assembly includes a second double pulley located on both sides of the fixed plate, and a first single pulley is provided on the bottom edge of the base plate relative to the second double pulley; the bottom of the first clamping assembly is provided with four second single pulleys.

[0013] Two of the steel wire ropes pass over the second double pulley, the first single pulley, and the second single pulley above it, and are connected to one side of the second clamping assembly. The other two steel wire ropes pass over the second single pulley and the second single pulley above it, and are connected to the other side of the second clamping assembly.

[0014] In order to guide the wire rope and ensure that it extends in a direction parallel to the column, the second double pulley and the first single pulley are provided with guide wheels for the wire rope to pass around on the side near the column, and their axes are perpendicular to the axis of the first single pulley.

[0015] To facilitate the connection and fixation of the wire rope to the second clamping assembly, the second clamping assembly is equipped with multiple lifting rings, and the end of the wire rope is connected to a hook that connects to the lifting ring.

[0016] To facilitate adjustment of the hook position and connection with the lifting ring, the hook adopts an OC-type basket hook.

[0017] In order to protect the output end of the telescopic cylinder from oil dripping onto it, a protective plate is connected to the side of the U-shaped plate near the telescopic cylinder, and the protective plate extends toward the body of the telescopic cylinder.

[0018] To facilitate the installation of the telescopic cylinder, an installation plate extends outward from the base plate, and the telescopic cylinder is installed on the installation plate. The base plate is provided with a base for supporting the main body of the telescopic cylinder.

[0019] The beneficial effects of this utility model are as follows: This utility model is a lifting mechanism for a disassembly and assembly machine. Firstly, by adopting a single telescopic cylinder combined with a wire rope and pulley assembly, the original multi-telescopic cylinder drive is simplified to a single-cylinder drive, significantly reducing the manufacturing cost of the equipment. Simultaneously, it reduces the internal space occupied by the equipment, making the overall structure more compact and simple, effectively solving the problem of the large size and complexity of traditional structures. The single telescopic cylinder drive eliminates the need for multi-cylinder coordinated control, simplifying the control system and reducing debugging difficulty and maintenance costs. Users no longer need to spend a lot of effort on complex multi-cylinder coordination debugging, improving the stability of equipment operation and effectively avoiding the problem of poor compatibility with hydraulic cylinders of different lengths due to insufficient control precision, significantly improving the practicality and work efficiency of the equipment. The combined use of the moving pulley group and the stationary pulley group utilizes the labor-saving characteristics of the pulley group, allowing the single telescopic cylinder to drive the second clamping assembly to move smoothly up and down with a smaller driving force, further improving the economy and reliability of the drive system.

[0029] Example

[0030] As mentioned in the background art, existing disassembly and assembly machines usually require a lifting assembly to drive the clamping assembly to move up and down to accommodate the fixing of hydraulic cylinders of different lengths. However, existing lifting assemblies usually adopt the form of multiple sets of telescopic cylinders arranged vertically, which is costly and difficult to coordinate and control, and occupies installation space. Therefore, the inventors have improved existing components and designed a new type of lifting assembly, which will be explained in detail below with reference to the figures.

[0031] This embodiment provides a lifting mechanism for a disassembly / assembly machine; see [link / reference]. Figure 1 The system includes multiple columns 1, with a first clamping component 2 fixedly installed at the upper end of each column 1. A second clamping component 3, which can move up and down, is installed between the multiple columns 1. In this solution, four columns 1 are provided, vertically distributed in a rectangular array. The first clamping component 2 is used to initially position the upper end of the hydraulic cylinder, and the second clamping component 3 can move up and down along the column 1 to clamp the lower end of the hydraulic cylinder, so as to achieve all-round fixation of hydraulic cylinders of different lengths. The first clamping component 2 and the second clamping component 3 can both adopt existing solutions, such as the clamping component disclosed in the applicant's earlier patent application, CN221389687U, "A Balancing Fixing Component for a Disassembly and Assembly Machine". No further details are provided.

[0032] In this embodiment, combined with Figure 2 At the bottom of the column 1, the column 1 is fixedly connected to a base plate 4 made of high-strength steel plate by welding. The upper surface of the base plate 4 is precision machined to ensure installation accuracy. A telescopic cylinder 5 is installed in the middle of the base plate 4. The output end of the telescopic cylinder 5 can make linear reciprocating motion in the horizontal direction. A fixing plate 6 is vertically welded to the edge of the base plate 4 opposite to the output end of the telescopic cylinder 5. The fixing plate 6 is made of high-strength alloy material. Multiple steel wire ropes 7 are fixed at the fixing plate 6. In order to realize the transmission and guidance of the steel wire ropes 7, the mechanism is equipped with a pulley assembly. The multiple steel wire ropes 7 pass around the pulley assembly and extend along the column 1 to the upper end of the second clamping assembly 3 and are fixed. The output end of the telescopic cylinder 5 is fixed to the pulley assembly and can drive the steel wire ropes 7 to move. By retracting the output end of the telescopic cylinder 5, the pulley assembly 8 can be moved, which in turn drives the steel wire ropes 7 to move, and finally drives the second clamping assembly 3 to rise.

[0033] Specifically, the pulley assembly includes a movable pulley block 8 and a stationary pulley block 9. The wire rope 7 passes sequentially through the movable pulley block 8 and the stationary pulley block 9 and connects to the second clamping assembly 3. Figure 3The movable pulley system 8 consists of a U-shaped plate 81 with an opening facing the fixed plate 6. The U-shaped plate 81 is made using a forging process, giving it high strength and rigidity. The output end of the telescopic cylinder 5 is connected to the back plate of the U-shaped plate 81. Two first double pulleys 82 are installed inside the U-shaped plate 81. The first double pulleys 82 are made of high-strength nylon. A double pulley refers to two pulleys with a coaxial design, and their surfaces are specially treated to reduce wear on the wire ropes 7. Four wire ropes 7 pass around the two first double pulleys 82 respectively. Utilizing the force-saving principle of the movable pulley system 8, the load on the telescopic cylinder 5 is effectively reduced.

[0034] Based on the above structure, the stationary pulley block 9 includes second double pulleys 91 located on both sides of the fixed plate 6. The second double pulleys 91 are also made of high-strength nylon, and their groove design perfectly matches the diameter of the wire rope 7, ensuring that the wire rope 7 will not come off during operation. A first single pulley 92 is provided on the edge of the base plate 4 opposite to the second double pulleys 91. Four second single pulleys 93 are provided at the bottom of the first clamping assembly, located at the angle to the column 1, and can rotate flexibly. Two of the wire ropes 7 pass over the second double pulleys 91, the first single pulley 92, and the second single pulley 93 above them and connect to one side of the second clamping assembly 3. That is, two wire ropes 7 extend towards the second double pulleys 91 and the first single pulley 92 on both sides. The other two wire ropes 7 pass over the second single pulley 93 and the second single pulley 93 above them and connect to the other side of the second clamping assembly 3. This staggered winding method makes the force on the second clamping component 3 more even during the lifting process, effectively avoiding tilting or jamming. It also allows the four steel wire ropes 7 to be connected to the edge of the second clamping mechanism respectively, making the lifting of the second clamping mechanism more stable.

[0035] To further optimize the running trajectory of the wire rope 7, guide wheels 94 are provided on the side of the second double pulley 91 and the first single pulley 92 near the column 1. The axis of the guide wheel 94 is perpendicular to the axis of the first single pulley 92, which allows the wire rope 7 to extend upward in a direction parallel to the column 1, preventing the wire rope 7 from shifting laterally during operation.

[0036] In addition, combined Figure 4 Four lifting rings 10 are distributed and installed on the upper surface of the second clamping assembly. The lifting rings 10 are forged from high-strength alloy steel and have high tensile strength. The end of the wire rope 7 is connected to an OC-type basket hook, which is made of high-quality stainless steel. Through the cooperation between the hook body and the lifting rings 10, it not only facilitates the quick connection and disassembly of the wire rope 7 and the second clamping assembly, but also allows for fine adjustment of the tension of the wire rope 7 by adjusting the thread structure of the basket hook, ensuring the stability of the entire transmission system.

[0037] Based on the above structure, a protective plate 12 is connected to the side of the U-shaped plate 81 near the telescopic cylinder 5. The protective plate 12 adopts an arc design and extends towards the main body of the telescopic cylinder 5, which can effectively protect the output end of the telescopic cylinder 5 and reduce the dripping of impurities such as oil stains onto the output end.

[0038] In this embodiment, a mounting plate 13 extends outward from the base plate 4. The mounting plate 13 has multiple mounting holes, and the telescopic cylinder 5 is fixedly mounted on the mounting plate 13 by bolts. At the same time, a base 14 is provided on the base plate 4 at the position corresponding to the main body of the telescopic cylinder 5. The base 14 is made of high-strength cast iron, and its top has a groove that matches the shape of the main body of the telescopic cylinder 5, which can support and position the main body of the telescopic cylinder 5, enhance the stability of the installation of the telescopic cylinder 5, and ensure the reliability of the entire drive system during operation.

[0039] When the height of the second clamping assembly 3 needs to be adjusted to accommodate hydraulic cylinders of different lengths, the telescopic cylinder 5 is activated. The output end of the telescopic cylinder 5 moves horizontally, causing the movable pulley block 8 to move synchronously. Due to the interaction between the movable pulley block 8 and the wire rope 7, the telescopic end drives the movable pulley block 8 to move, and then, through its cooperation with the wire rope 7, generates traction force on the wire rope 7, thereby driving the second clamping assembly 3 to move smoothly up and down along the column 1. By precisely controlling the telescopic stroke of the telescopic cylinder 5, the height of the second clamping assembly 3 can be adjusted arbitrarily within a certain range, thus meeting the clamping requirements of hydraulic cylinders of different lengths.
