Description

Technical Field

[0001] This utility model relates to the technical field of idler roller disassembly tools, and in particular to a disassembly tool for a straight idler roller on the underside of a conveyor belt. Background Technology

[0002] Conveyor belts are very common in daily life. They are made of flexible material and can deform to facilitate the transport of materials such as coal. When using a conveyor belt, idlers are needed to support it. As the use of idlers increases over time, they need to be maintained regularly.

[0003] The idler roller consists of two rollers, an upper one and an lower one. When disassembling and maintaining the upper middle idler roller and the lower middle idler roller, two workers are required to work together and the tool slot steel needs to be disassembled. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model solves the following technical problem: Since the idler roller includes two rollers (upper and lower), disassembling and maintaining the upper and lower intermediate idlers requires the cooperation of two workers and the disassembly of the tool slot steel. Therefore, this utility model provides a tool for disassembling the lower straight idler roller of a conveyor belt.

[0005] To achieve the above objectives, this utility model provides: A tool for disassembling a straight idler roller on the underside of a conveyor belt includes two threaded rods, each end of which is fixedly fitted with a support ring. The outer sides of both threaded rods are threaded with a manual mechanism, and the outer sides of both threaded rods are movably fitted with a support structure.

[0006] Preferably, the same crossbar is movably installed within the two support rings on the same side.

[0007] Preferably, the manual structure includes a threaded sleeve, which is threaded to the outside of the externally threaded rod, and a handle is welded to the outside of the threaded sleeve.

[0008] Preferably, a sleeve is movably installed on the outer side of the external threaded rod, and an "F"-shaped bracket is fixedly installed on the outer side of the sleeve, with an anti-slip pad provided on the inner side of the "F"-shaped bracket.

[0009] Compared with the prior art, the advantages of this utility model are: 1. Bidirectional universal design No need to adjust the clamping position: By flexibly inserting the crossbar above and below the belt (below the upper belt or below the lower belt), the same tool can adapt to the disassembly requirements of the upper and lower intermediate idlers, and the contact position between the tool and the frame slot remains unchanged.

[0010] Uniform force direction: Regardless of whether the upper or lower roller is disassembled, the tool always bears a downward thrust, simplifying the operation logic and reducing the risk of misoperation.

[0011] 2. Threaded mechanical force amplification structure Manual thread drive: By rotating the handle, the threaded sleeve moves along the external thread rod, converting human power into a stable linear thrust. It has the advantage of saving mechanical labor and is especially suitable for lifting heavy conveyor belts.

[0012] Precise control: The threaded drive provides progressive displacement adjustment, avoiding instantaneous overload deformation of the belt and protecting the integrity of the equipment.

[0013] 3. Modular support system "F" type bracket and anti-slip pad: The irregular structure of the "F" type bracket can tightly lock into the channel steel of the conveyor belt frame. Combined with the inner anti-slip pad design, it enhances the fixation of the tool and prevents it from sliding or dislodging during operation.

[0014] Sleeve linkage structure: The movable connection between the external threaded rod and the sleeve ensures that the thrust is evenly transmitted to the support, improving the overall structural stability.

[0015] 4. Dynamic support technology for crossbars Belt lifting protection: The crossbar passes through the support ring to form a rigid fulcrum. During disassembly, the lifting belt disperses local pressure, avoiding belt scratches or deformation that may be caused by traditional pry bars.

[0016] Adaptive load: The symmetrical layout of the crossbar length and the double external threaded bar achieves force balance and reduces the risk of stress concentration on one side.

[0017] 5. Ergonomic optimization Feasibility of single-handed operation: The welded position of the handle rod and the threaded sleeve form a lever structure, allowing a single person to complete the lifting and disassembly actions, reducing the need for manpower.

[0018] Compact and portable: The split threaded rod and detachable crossbar design make it easy to store and carry, adapting to narrow working environments.

[0019] 6. Safety Redundancy Design Double protection against slippage and detachment: The interlocking mechanism of the anti-slip mat and the "F"-shaped bracket forms a double insurance, preventing tools from accidentally detaching from the frame under high pressure and reducing the risk of workplace injury.

[0020] No power dependence: The purely mechanical structure avoids the potential for electro-hydraulic system failures and is suitable for complex working environments such as mines and factories.

[0021] This utility model tool, through its integrated functionality and user-friendly design, solves the problems of poor tool compatibility, low efficiency, and numerous safety hazards in traditional idler roller disassembly, significantly improving the reliability and economy of maintenance operations.

[0024] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0025] See Figure 1-2 As shown, a tool for disassembling a straight idler roller on the lower side of a conveyor belt includes two external threaded rods 1. Both ends of the two external threaded rods 1 are fixedly installed with support rings 11. The outer sides of the two external threaded rods 1 are threaded with a manual structure, and the outer sides of the two external threaded rods 1 are movably installed with a support structure.

[0026] In this embodiment, the same crossbar 2 is movably installed inside the two support rings 11 located on the same side.

[0027] In this embodiment, the manual structure includes a threaded sleeve 3, which is threaded to the outside of the external threaded rod 1, and a handle rod 31 is welded to the outside of the threaded sleeve 3.

[0028] In this embodiment, a sleeve 4 is movably installed on the outer side of the external threaded rod 1, and an "F"-shaped bracket 41 is fixedly installed on the outer side of the sleeve 4. An anti-slip pad is provided on the inner side of the "F"-shaped bracket 41.

[0029] Operating principle: This tool is used for disassembling and assembling the upper and lower intermediate idlers. When disassembling the upper intermediate idler, the crossbar 2 passes under the upper belt. The crossbar 2 pushes the belt upwards. The two "F"-shaped brackets 41 are positioned relative to the tool slot steel of the conveyor belt frame. The handle rod 31 drives the threaded sleeve 3 to rotate along the external threaded rod 1. The external threaded rod 1 pushes the 41 downwards, causing the upper belt to move upwards, facilitating the disassembly of the upper intermediate idler. When disassembling the lower intermediate idler, the crossbar 2 passes under the lower belt, pulling the lower belt upwards. Essentially, regardless of whether the upper or lower intermediate idler is being disassembled, the tool receives a downward force, and the position of the tool slot steel does not need to be changed.

[0030] This utility model is not limited to the above-described preferred embodiment. Anyone can derive other products in various forms under the guidance of this utility model. However, regardless of any changes made in its shape or structure, any technical solution that is the same as or similar to this utility model is within its protection scope.
