Description

Technical Field

[0001] The utility model relates to the technical field of maintenance tooling, and particularly relates to a tooling for maintaining an eccentric assembly. Background Art

[0002] Refer to Figure 1 , in the tobacco industry's silk-making production line operation, the vibrating conveyor equipment is a common and very important conveying equipment, and its transmission assembly is an eccentric assembly 100. Due to the influence of long-term operation and the working environment, the wear and faults of the eccentric assembly occur frequently, so it needs to be repaired and replaced regularly. However, due to the generally large self-weight of the eccentric assembly mechanism and the narrow operation space, and the installation position is mostly above 2M height, the existing maintenance methods are often inefficient, complex in operation, and prone to secondary damage, which not only increases the maintenance cost but also may affect the normal operation of the equipment.

[0003] In view of the above problems, the creator of the utility model finally obtained the present utility model through long-term research and practice. Content of the Utility Model

[0025] As Figures 2 - 5 shown, in this embodiment, the tooling for repairing the eccentric assembly includes a fixing frame 1, and the fixing frame 1 includes a body 11. One end of the body 11 has a hook portion 12, and the opposite end has a connecting portion 13. A positioning member 3 is detachably fixed on the connecting portion 13, an adjusting member 4 is hinged on the positioning member 3, and a rotating shaft sleeve 5 is rotatably connected to the adjusting member 4. The fixing frame is used to carry the eccentric assembly 100, the positioning member 3 is used to accurately fix the position of the eccentric assembly, and the adjusting member 4 is used to adjust the angle and position of the eccentric assembly.

[0026] In a specific embodiment, the tooling for repairing the eccentric assembly further includes a rope 6. One end of the rope 6 is fixed with a hook 61, and the other end is a free end. The hook portion 12 is used to be clamped on one side of the frame of the vibrating conveyor, and the rotating shaft sleeve 5 is located on the other side of the frame. When in use, the fixing frame 1 is installed at the frame 300 of the vibrating conveyor, then the hook 61 is hooked on the positioning member 3, and the rope 6 is passed around the frame 300 as Figure 5 , Figure 1 shown, passed through between the eccentric part 102 and the transmission bearing seat 101, then passed around the rotating shaft sleeve 5 and kept the rope taut, and the eccentric assembly 100 is driven to lift and lower by the rope 6.

[0027] The locking structure is provided on the hook portion 12 for locking the hook portion 12 on the frame 300 of the vibrating conveyor. Preferably, the locking structure includes a locking bolt 2, and the hook portion 12 is fixed on the frame of the vibrating conveyor by the locking bolt 2. This locking structure can quickly lock the eccentric assembly after adjustment is completed to prevent it from moving during the maintenance process.

[0028] During use, the fixing frame 1 is installed at the frame 300 of the vibrating conveyor, and the locking bolt 2 is initially pre-tightened. Then, the hook 61 is hooked on the positioning member 3, and the rope 6 is passed around the frame 300 as shown in Figure 5 、 Figure 1 , passed through the space between the eccentric portion 102 and the transmission bearing seat 101, then passed around the rotating bushing 5 and kept the rope taut, and the locking bolt 2 was fully fixed. The eccentric assembly 100 is driven to lift and lower by the rope 6.

[0029] When disassembling the eccentric assembly 100: After removing the fixing bolts of the eccentric connecting rod 200 and the transmission bearing seat 101, manually gradually reduce the pulling force, or slowly lower it electrically to ensure that the eccentric assembly 100 slowly descends to the ground or the operating platform for maintenance. When installing the eccentric assembly 100: Manually gradually increase the pulling force, or slowly raise it electrically to lift the eccentric assembly 100 to the installation position and maintain the pulling force, and then install the fixing bolts of the transmission bearing seat 101 and the eccentric connecting rod 200, etc.

[0030] Preferably, the fixing frame 1 is made of high-strength steel, has sufficient rigidity and stability, can bear the weight of the eccentric assembly, and provides a stable working platform. The main body 11 is integrally in a trapezoidal structure with an open upper end. The hook portion 12 is located at the bottom of the trapezoid. The fixing frame 1 is used to be fixed on the frame 300 of the vibrating conveyor. The structure of the main body 11 has sufficient rigidity and stability.

[0031] On the basis of the above embodiments, the adjusting member 4 includes two connecting rods 41. One end of the connecting rod 41 is connected to the positioning member 3, and the other end is connected to the rotating bushing 5. The length of the connecting rod 41 is adjustable. By manually adjusting the length of each connecting rod 41, the vertical and horizontal positions of the eccentric assembly can be accurately adjusted to facilitate disassembly and installation.

[0032] Based on the above embodiments, the positioning member 3 can be adjusted according to different models of eccentric assemblies through cooperation with the rope, ensuring that the axis of the eccentric assembly is perpendicular to the center line of the tooling. The positioning member 3 is detachable, that is, different positioning members 3 can be replaced according to different models of eccentric assemblies, so as to ensure that the axis of the eccentric assembly is perpendicular to the center line of the tooling. Exemplarily, the positioning member 3 can have different structures such as straight rod shape, arc rod shape, concave rod shape, etc., and is designed according to the eccentric assembly. Therefore, the adjustable design of the tooling enables it to adapt to various models of eccentric assemblies, with good versatility and flexibility.

[0033] Taking the ZGC09 type vibrating conveyor as an example, the original maintenance mode was a multi-person collaboration and relied on experienced technicians. The operation process was cumbersome and had a certain risk of mechanical injury to people. Moreover, the general maintenance time in the market was usually more than 3 hours. This tooling integrates functions of positioning, adjustment and locking, greatly simplifies the maintenance process, improves work efficiency, reduces the possibility of human errors and eliminates the risks existing in the maintenance process. At the same time, it also reduces the maintenance cost. Due to the improvement of maintenance efficiency, the service life of the eccentric assembly is extended, achieving the purpose of cost reduction and efficiency increase and saving spare parts cost.

[0034] The above are only the preferred embodiments of the present utility model, which are illustrative rather than restrictive to the present utility model. The structures and connection methods of various components in the present utility model can all be changed. Any equivalent transformation and improvement made on the basis of the technical solution of the present utility model should not be excluded from the protection scope of the present utility model.
