Description

Technical Field

[0001] This utility model patent belongs to the technical field of belt conveyor equipment, specifically relating to a mobile conveyor belt vulcanization platform. Background Technology

[0002] During operation, multiple conveyor belts are typically connected in a loop to achieve continuous transport. The quality of the conveyor belt splice directly affects the belt's efficiency and lifespan. This is especially true for long-distance, high-strength conveyor belts. With increasing service life, conveyor belts may experience problems such as wear and aging, which can impact their performance and safety. Therefore, to ensure the safe and efficient operation of the production line, while improving production efficiency and material discharge quality, regular or timely replacement of conveyor belts is essential. The entire conveyor belt maintenance process includes four main steps: belt replacement, setting up the vulcanization platform, splice fabrication, and vulcanization bonding. Strictly adhering to professional vulcanization standards takes approximately 90-100 hours. Currently, online belt maintenance time is often constrained by production schedules, sometimes sacrificing vulcanization quality to save time. Furthermore, the time required for belt replacement, splice fabrication, and vulcanization bonding is subject to strict process requirements and cannot be shortened.

[0003] The problem is that the replacement efficiency of conveyor belts in mining conveyors is low, the replacement time is long, and the vulcanization process has strict requirements that cannot be shortened.

[0004] The current situation of conveyor belts, which consume a lot of manpower and resources, restricts the improvement of conveyor operating time and transportation efficiency. The conveyor belt maintenance and replacement process includes four main steps: belt replacement, setting up a vulcanization platform, joint fabrication, and vulcanization bonding. While the vulcanization process requirements for belt replacement, joint fabrication, and vulcanization bonding are standardized and their durations cannot be changed, the process time can be shortened by directly fabricating a mobile conveyor belt vulcanization platform in the vulcanization platform setup step. Therefore, the technical problem solved by this utility model is: 1. Design and manufacture a mobile conveyor belt vulcanization platform, which can be used multiple times after a single investment. It facilitates rapid installation before vulcanization and rapid dismantling after vulcanization, enabling the quick commencement of hot vulcanization work on the conveyor belt, saving manpower and resources, shortening conveyor belt inspection and maintenance time, and improving the conveyor's transport efficiency. 2. Using a mobile conveyor belt vulcanization platform eliminates safety hazards. Normally, when vulcanizing conveyor belt joints, maintenance personnel need to stand on a 1.8-meter-high frame, posing a safety risk and increasing the risk of falls from height. Now, workers can operate from a mobile conveyor belt vulcanization platform, ensuring their safety. 3. Using a mobile conveyor belt vulcanization platform can ensure the quality of the vulcanization joint and facilitate the alignment of the conveyor belt joint. All six points at both ends of the joint are on the same straight line. After alignment, there are belt clamps at both ends of the vulcanization platform to prevent displacement of the central axis at both ends of the conveyor belt. After vulcanization, the conveyor belt will not run off-center and can operate normally.

[0005] To address the aforementioned problems, this utility model proposes a mobile conveyor belt vulcanization platform. Utility Model Content

[0006] To address the aforementioned issues, this invention provides a mobile conveyor belt vulcanization platform. This platform allows for rapid installation before and removal after vulcanization, facilitating the quick commencement of hot vulcanization of the conveyor belt and achieving rapid completion of the conveyor belt joint vulcanization process.

[0007] To achieve the above-mentioned technical effects, this utility model is implemented through the following technical solution: a mobile conveyor belt vulcanization platform, including a base frame, a workbench, safety railings, lifting lugs, a belt clamping and centering mechanism, a ladder, and vulcanization equipment. The base frame is installed on the frame of the conveyor belt. Workbenches are installed on the front and rear sides above the base frame. Removable safety railings are installed around the workbench. The lifting lugs for hoisting are welded to the left and right sides of the crossbeam in the base frame or to the left and right sides of the workbench. The belt clamping and centering mechanism is installed in the middle of the workbench. The ladder is welded to the side of the workbench. The vulcanization equipment is detachably installed in the middle of the base frame.

[0008] Preferably, the base frame also includes crossbeams, vertical beams, and supports. Several longitudinal vertical beams are welded onto the several transverse crossbeams, and the supports are divided into two groups, front and rear, and welded to the junctions of the crossbeams and vertical beams respectively.

[0009] Preferably, the height of the upper surface of the workbench to the bottom of the frame does not exceed the combined height of the lower vulcanizing beam, the water pressure plate, and the heat-insulating wooden board in the vulcanizing equipment.

[0010] Preferably, the side of the workbench facing the vulcanizing equipment is provided with a 70° angled side according to the angle of the heating plate of the vulcanizing machine, and the upper surface of the workbench is marked with a center line extending forward and backward on both sides.

[0011] Preferably, the safety railing also includes a base, support rods, a safety rope (not shown in the figure), and a triangular warning tape (not shown in the figure). The base is welded to the four diagonal corners of the workbench, the support rods are inserted into the base, and the support rods are connected to each other by the safety rope. A triangular warning tape is provided on the safety rope.

[0012] Preferably, the tape clamping and centering mechanism further includes a semi-circular clamp, screw holes, bolts (not shown in the figure), and tape clamps. The semi-circular clamp is welded to the left and right sides of the middle of the workbench. A screw hole is provided in the center of the semi-circular clamp. The tape clamps are provided with screw holes at both ends and are installed on the semi-circular clamp by bolts for clamping the tape joint on the workbench. In this mechanism, the two tape clamps can be clamped by tightening the bolts.

[0013] The beneficial effects of this utility model are: 1. A mobile conveyor belt vulcanization platform that simplifies the operation process, shortens the vulcanization time, reduces the difficulty of work, improves work efficiency and comfort, is easy to assemble and disassemble, and is quick and flexible to move and transport. 2. Design and manufacture a mobile vulcanizing platform that can be used multiple times in subsequent vulcanization processes. This allows for a one-time investment and multiple uses, reducing labor costs and improving production efficiency. Compared to temporarily erected vulcanizing platforms, a mobile vulcanizing platform offers greater flexibility and superior performance, while also saving time on setting up temporary platforms. 3. Without this portable vulcanizing platform, temporarily welding and fabricating a vulcanizing platform would significantly increase the amount of welding and welding time. Dismantling would require cutting, making the maintenance process cumbersome and increasing the workload of equipment maintenance personnel. 4. Using a mobile conveyor belt vulcanization platform eliminates safety hazards. Previously, when vulcanizing conveyor belt joints, maintenance personnel had to stand on a 1.8-meter-high frame, posing a safety risk and increasing the risk of falls. Now, workers can operate from a mobile conveyor belt vulcanization platform equipped with safety railings, ensuring personnel safety and preventing falls. 5. Using a mobile conveyor belt vulcanization platform can ensure the quality of the vulcanization joint, facilitate the alignment of the conveyor belt joint, and ensure that all six points at both ends of the joint are on the same straight line. After alignment, there are belt clamps at both ends of the vulcanization platform to prevent displacement of the central axis at both ends of the conveyor belt. After vulcanization, it can ensure that the conveyor belt does not run off track and can operate normally. 6. The workbench can be used by maintenance personnel to make joints, strip steel wire ropes, and remove rubber. Although the maintenance site for the conveyor is limited, the workbench maximizes the use of the limited space. The workbench also has a joint alignment and centering function, which makes it easy to align the conveyor belt joints and ensure that they are in the centerline position. 7. Safety guardrails can be used to protect operators from accidental falls when working or engaging in activities at heights. Furthermore, the fact that they are made into detachable safety guardrails makes them easy to install, dismantle, and transport. 8. Lifting lugs are used during the installation and dismantling of the vulcanizing platform. By connecting the crane hook to the lifting lugs, the equipment can be lifted and installed in the designated position, shortening the conveyor belt replacement and maintenance time and improving production efficiency. 9. The tape clamps are designed and fabricated in the middle of the workbench, with tape clamps welded onto both workbenches. Two semi-circular steel plates are welded to both sides of the central axis of the workbench, with bolt holes drilled in the center of each semi-circle. Two 15# channel steels are also used, with bolt holes drilled at both ends, to create the movable parts of the clamps. After the tape is aligned, the two tape clamps are used to clamp and fix the tape, ensuring that the tape does not shift, thus guaranteeing the normal and defect-free completion of the vulcanization process.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. Example 1

[0016] like Figures 1 to 4 As shown, the existing technology in this embodiment has the following problems: Based on the defects of the conveyor belt vulcanization process in the current technology, the inventor wants to manufacture a mobile conveyor belt vulcanization platform that can be used multiple times, shortens the conveyor belt inspection and maintenance time, improves the conveyor's transportation efficiency, eliminates safety hazards, and facilitates the alignment of the conveyor belt joint. Therefore, the inventor provides a mobile conveyor belt vulcanization platform, including a base frame 1, a workbench 2, a safety railing 3, lifting lugs 4, a belt clamping and centering mechanism, a ladder 5, and vulcanization equipment 6. The base frame 1 is installed on the frame 7 of the conveyor belt. The workbench 2 is installed on the front and rear sides above the base frame 1. The workbench 2 is equipped with detachable safety railings 3 around its perimeter. The lifting lugs 4 for hoisting are welded to the left and right sides of the crossbeam 8 in the base frame 1 or to the left and right sides of the workbench 2. The belt clamping and centering mechanism is installed in the middle of the workbench 2. The ladder 5 is welded to the side of the workbench 2. The vulcanization equipment 6 is detachably installed in the middle of the base frame 1.

[0017] Furthermore, the base frame 1 also includes crossbeams 8, vertical beams 9, and supports 10. Several longitudinal vertical beams 9 are welded onto the several transverse crossbeams 8, and the supports 10 are divided into two groups, front and rear, and are welded to the junction of the crossbeams 8 and the vertical beams 9 respectively.

[0018] Furthermore, the height of the upper surface of the workbench 2 to the bottom of the frame 1 shall not exceed the combined height of the lower vulcanizing beam 11, the water pressure plate, and the heat insulation board in the vulcanizing equipment 6.

[0019] Furthermore, the side of the workbench 2 facing the vulcanizing equipment 6 is provided with a 70° angled bevel according to the angle of the heating plate of the vulcanizing machine, and the upper surface of the workbench 2 is marked with a center line 16 extending to the front and rear sides.

[0020] Furthermore, the safety railing 3 also includes a base (not shown in the figure), support rods (not shown in the figure), safety ropes (not shown in the figure), and triangular warning tapes (not shown in the figure). The base is welded to the four diagonal corners of the workbench 2, the support rods are inserted into the base, and the support rods are connected to each other by safety ropes. Triangular warning tapes are provided on the safety ropes.

[0021] Furthermore, the tape clamping and centering mechanism also includes a semi-circular clamp 12, a screw hole 13, a bolt (not shown in the figure), and a tape clamp 14. The semi-circular clamp 12 is welded to the left and right sides of the middle part of the workbench 2. The semi-circular clamp 12 has a screw hole 13 in the center. The tape clamp 14 has screw holes 13 at both ends and is installed on the semi-circular clamp 12 by bolts for clamping the tape on the workbench 2. In this mechanism, the two tape clamps 14 can be clamped to the tape joint 15 by tightening the bolts. Example 2

[0022] Based on the above embodiments, the inventors have applied them in practice, and the specific applications are as follows: A movable vulcanizing platform is constructed by welding together a crossbeam 8 made of 14# channel steel, vertical beams 9 made of 12# channel steel, support columns 10, and a workbench 2. In use, it is assembled with the upper and lower beams of the vulcanizing machine or other vulcanizing equipment 6. The type of channel steel is determined according to the vulcanizing machine and the number of joint overlaps. The workbench 2 is made of 5mm sheet metal, and the angle of its inclined side is determined according to the angle of the heating plate of the vulcanizing machine. When assembled with the vulcanizing machine, the height of the workbench 2 must not be less than 67mm. Multiple layers and multiple passes of welding are used, and the crossbeams 8 and vertical beams 9 are welded together to form a mesh structure that enhances strength and prevents deformation under stress during use.

[0023] The crossbeam 8 is constructed from five 7800mm long No. 14 channel steel sections welded together. Other components are joined to the crossbeam 8 with 45° bevels and welded. The crossbeam 8 is also welded to the vertical beams 9 and the support columns 10. The crossbeam 8, by connecting the vertical beams 9 and the support columns 10, enhances the overall stability and load-bearing capacity of the platform structure. The crossbeam 8 is directly assembled to the conveyor frame 7. The crossbeam 8 serves as a support, particularly for the pallet vulcanizing machine, and can withstand the longitudinal loads generated during the vulcanizing platform's operation, ensuring the stability and safety of the vulcanizing platform during vulcanizing operations. The vertical beam 9 is made of six 2000mm long No. 12 channel steels welded together and welded to the horizontal beam 8 to form a mesh structure base. It serves as a supporting element of the vulcanizing platform structure, bearing vertical loads and static and dynamic loads to ensure the safety of the vulcanizing platform. The vertical beam 9 can provide lateral connection by connecting other horizontal beams 8 or frames to increase the overall rigidity and stability of the vulcanizing platform structure. The support column 10 is constructed from eight 670mm long No. 12 channel steels welded together. Connected to components such as the crossbeam 8 and the worktable 2, the support column 10 forms a stable support system, effectively distributing the load on the upper part of the vulcanizing platform. In the vulcanizing platform structure, the support column 10 plays a crucial supporting role. Its main task is to transfer the weight of the upper part of the worktable 2 to the frame 7, supporting the entire weight of the worktable 2 and providing a stable frame.

[0024] Workbench 2 is 2600mm long and 1900mm wide. Since workbench 2 bears a small load and does not support equipment, a grid-like frame can be formed by welding #5 angle steel. Then, an 8mm patterned iron plate is welded and laid on top of the grid frame. After workbench 2 is completed, it is welded to the top of support column 10. Workbench 2 is welded symmetrically to both ends of the vulcanizing platform. This facilitates joint fabrication and centerline alignment for operators. The safety railing is made of galvanized pipes. The welding positions are at the four diagonal corners of the vulcanizing platform. First, weld 10 cm DN25 galvanized pipes to the four corners at the bottom. Then, insert 1.5 m DN20 galvanized pipes into the DN25 galvanized pipes one by one. Install and tie hemp ropes and triangular warning tapes between the galvanized pipes to make a detachable safety railing for easy installation, dismantling and transportation. Lifting lugs 4 are welded to the crossbeam 8, two on each side, for a total of four. Lifting lugs 4 provide connection points for cranes or other lifting equipment to facilitate the lifting and movement of the vulcanizing platform. During the installation and dismantling of the vulcanizing platform, the lifting lugs 4 are installed on the vulcanizing platform, and the crane hook is connected to the lifting lugs 4 to lift the equipment and install it in the designated position.

[0025] The tape clamping and centering mechanism is designed and fabricated in the middle of workbench 2. Tape clamping plates 14 are welded onto both workbench 2. Two semi-circular steel plates are welded to both sides of the central axis of workbench 2, with bolt holes drilled in the center of each semi-circle. Two 15# channel steels are also used, with bolt holes drilled at both ends, to create the movable parts of the clamping plates. After the tape is aligned, the two tape clamping plates 14 are used to clamp and fix the tape, ensuring that the tape does not shift, thus guaranteeing the normal and defect-free completion of the vulcanization process. Then, a ladder is welded and made on the outside of the vulcanizing platform to facilitate personnel going to and from get off work and maintenance, and to eliminate the risk of falling from heights and injuring people.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0027] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
