Description

Technical Field

[0001] The invention relates to the technical field of mechanical maintenance tools, and in particular to a portable belt roller bearing removal tool. Background Art

[0002] In today's grand scene of industrial production, belt conveyors are like flowing lifelines, continuously transporting various materials to various production links. However, during the long-term operation of belt conveyors, various problems will inevitably occur in the bearings on the belt rollers, requiring regular maintenance and replacement.

[0003] At present, when replacing belt roller bearings, the traditional disassembly method is mainly to use hammers, crowbars and other tools for knocking and prying. This method has many disadvantages. First of all, low efficiency is one of its most obvious disadvantages. Using hammers and crowbars for disassembly requires operators to have certain strength and skills, and the operation process is relatively cumbersome and takes a lot of time and energy. In industrial production, time is money, and inefficient maintenance methods will seriously affect production progress and bring huge economic losses to enterprises.

[0004] Secondly, traditional disassembly methods are prone to damage to the belt rollers and bearings. The hammering and prying force of hammers and crowbars is difficult to control, and it is easy to cause scratches, deformation and other damage to the surface of the belt roller and bearings during the disassembly process. Once the belt roller or bearing is damaged, additional repair or replacement is required, which will undoubtedly increase the maintenance cost. Moreover, damaged belt rollers and bearings may affect the running stability and accuracy of the belt conveyor, and may even cause equipment failure, further affecting the normal production.

[0005] In addition, the traditional disassembly method requires a large operating space. In some industrial production sites, the space is often limited, especially in some old factories or narrow working areas, it is difficult to provide enough operating space for the traditional disassembly method. This makes it very difficult or even impossible to replace the belt roller bearing in these occasions.

[0006] Finally, traditional disassembly methods also have certain safety risks. When operators use hammers and crowbars to dismantle, they need to knock and pry hard, which can easily cause the tools to slip out of their hands or rebound, causing harm to the operators. Moreover, during the operation, the operators may sprain their waists, arms and other parts due to improper force, posing a threat to their own health.

[0007] In summary, the traditional belt roller bearing removal method has problems such as low efficiency, easy damage to equipment, large operating space and safety risks, which can no longer meet the needs of modern industrial production. Therefore, a convenient, efficient and safe belt roller bearing removal device is urgently needed to solve these problems. Summary of the invention

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0029] Example 1

[0030] Reference Figure 1-2 , which is the first embodiment of the present invention, provides a portable belt roller bearing removal tool, the device includes a support unit 100, including a support frame 101, a movable slide rail 102 arranged on the support frame 101, and a support part 103 arranged on the support frame 101. The support frame 101 serves as the basic structure of the entire tool, and is used to stably place and support the entire bearing removal tool to ensure stability and safety during operation. It is arranged on the support frame 101 and can be adjusted to adapt to bearings of different sizes and positions, thereby increasing the flexibility and adaptability of the tool.

[0031] The pulling unit 200 includes a sliding fixture 201 disposed on the movable slide rail 102 for clamping the bearing. The sliding fixture 201 can move along the slide rail to adapt to bearings of different positions and sizes, ensuring that the bearing can be firmly grasped during the disassembly process, and a pulling part 202 disposed on the support part 103, which is a component that actually performs the pulling operation. The pulling part 202 is connected to the sliding fixture 201 to transmit the pulling force to the bearing, thereby pulling the bearing out of the belt roller.

[0032] Among them, the support part 103 includes a support component 103a arranged on the support frame 101, and a fixing component 103b arranged on the support component 103a. The support component 103a is the core of the support part 103, which is directly connected to the support frame 101. During the process of drawing the bearing, the support component 103a must be strong enough to ensure that it will not be deformed or damaged when force is applied. The function of the fixing component 103b is to fix the drawing part 202 or related operating parts on the support component 103a to ensure that the position of these parts is stable during the drawing process and will not be displaced or rotated, thereby ensuring the accuracy and safety of the drawing operation, and resisting the vibration and impact that may be generated during the drawing process.

[0033] During use, the staff turns off the power supply of the belt conveyor and hangs a warning sign at the power switch. To loosen the belt, adjust the conveyor tensioning device. Slowly turn the belt to confirm that it is in a completely relaxed state and will not interfere with subsequent operations. Place the belt roller on the support frame 101, and place it stably on the support frame 101 through the support component 103a and the fixing component 103b. Clamp it with the sliding clamp 201 to prevent it from detaching from the support frame 101, and then remove the bearing through the pulling part 202.

[0034] Example 2

[0035] Reference Figure 1-2 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the support assembly 103a includes a buffer gasket 103a-1 arranged on the support frame 101, and two groups of square baffles 103a-2 arranged on the edge of the support frame 101. The buffer gasket 103a-1 can reduce the impact and vibration of the support frame 101 and the belt roller during the pulling process, and can also reduce noise. The square baffles can provide additional stability and limiting force to prevent the belt roller from lateral movement or rolling during the pulling process, thereby ensuring that the roller remains in the correct position during the pulling process.

[0036] Compared with Example 1, further, the fixing assembly 103b includes a fixing block 103b-1 arranged between two groups of square baffles 103a-2, and an elastic gasket 103b-2 arranged on the fixing block 103b-1. The fixing block 103b-1 can ensure the stability and accuracy of the drawing part 202 during the drawing process. The material of the fixing block 103b-1 is steel or aluminum alloy to ensure its strength and durability. It can be connected to the support frame 101 and the square baffle by bolts, welding or other fastening methods to ensure the stability of the entire fixing assembly 103b. The elastic gasket 103b-2 provides buffering when fixing the drawing part 202, reduces the vibration and impact caused by the pulling force, and protects the drawing part 202 and the pulled bearing from damage. The material of the elastic gasket 103b-2 is rubber or plastic to absorb the impact force and vibration during the drawing process, reduce noise, and extend the service life of tools and equipment.

[0037] Compared with Example 1, the drawing part 202 further includes a power component 202a arranged on the support frame 101, and an adjustment component 202b connected to the power component 202a. The power component 202a makes the drawing operation more labor-saving and efficient, and the adjustment component 202b facilitates the staff to adjust the size or direction of the drawing force as needed to adapt to bearings of different sizes and types, thereby ensuring the accuracy and safety of the drawing operation.

[0038] Compared with Example 1, further, the power component 202a includes a tensioning piston 202a-1 arranged between two groups of square baffles 103a-2, and also includes a pulling rod 202a-2 arranged on the side of the tensioning piston 202a-1 away from the square baffle 103a-2. The tensioning piston 202a-1 is pushed by fluid pressure (hydraulic oil or compressed air) to achieve the pulling of the bearing, and can directly transmit the pulling force to achieve the pulling of the bearing. The pulling rod 202a-2 transfers the force generated by the tensioning piston 202a-1 to the bearing to achieve the pulling of the bearing. The pulling rod 202a-2 can be designed to be telescopic to meet the pulling requirements of different depths.

[0039] Compared with Example 1, further, the adjustment assembly 202b includes a pressure relief valve 202b-1 arranged on the side of the pulling rod 202a-2 away from the tensioning piston 202a-1, and an operating handle 202b-2 arranged on the side of the pressure relief valve 202b-1 away from the pulling rod 202a-2. The pressure relief valve 202b-1 controls the pulling force applied by the pulling rod 202a-2, so that the staff can release the pressure in the tensioning piston 202a-1 when needed, thereby reducing or stopping the application of the pulling force, ensuring that the bearing will not be over-pulled or the pressure is safely released after the pulling operation is completed.

[0040] The remaining structures are the same as those of Example 1.

[0041] Example 3

[0042] Reference Figure 1-2 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that an adjustment gasket adapted to the belt roller is attached to the surface of the sliding clamp 201 close to the support frame 101. The adjustment gasket can adapt to belt rollers of different diameters or widths to ensure that the contact between the sliding clamp 201 and the roller is uniform and stable. At the same time, the gasket can reduce the direct contact between the sliding clamp 201 and the belt roller, thereby reducing wear and damage.

[0043] Compared with Example 2, further, fixed claws corresponding to the two ends of the belt roller are provided on both sides of the sliding clamp 201. The fixed claws can provide additional stability and fixing force to ensure that the belt roller does not move axially or radially during the bearing pulling process. The fixed claws correspond to the two ends of the belt roller and can tightly grasp the roller to prevent it from sliding or rotating during operation.

[0044] Compared with Example 2, further, a pressure gauge for monitoring the internal pressure of the tensioning piston 202a-1 is provided on the tensioning piston 202a-1 to ensure that the drawing operation is performed within a safe and controllable parameter range, so as to facilitate the staff to make corresponding adjustments.

[0045] The remaining structure is the same as that of Example 2.
