Description

Technical Field

[0001] The patent of this invention belongs to the technical field of belt conveyor equipment, and specifically relates to a movable conveyor belt vulcanizing platform. Background Art

[0002] Conveyor belts often require multiple belts to be connected in a loop for continuous conveying. The quality of conveyor belt joints directly impacts the belt's effectiveness and service life. This is especially true for long-distance, high-strength conveyor belts. Over time, conveyor belts may develop issues such as wear and aging, which can affect their performance and safety. Therefore, to ensure safe and efficient production line operation while improving productivity and material quality, regular or timely conveyor belt replacement is essential. The entire conveyor belt maintenance process involves four key steps: belt replacement, vulcanization platform construction, joint fabrication, and vulcanization bonding. Strictly following professional vulcanization standards takes approximately 90-100 hours. Currently, online belt maintenance time is often constrained by production schedules, sometimes sacrificing vulcanization quality. The time required for belt replacement, joint fabrication, and vulcanization bonding is strictly controlled by the process and cannot be shortened.

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

[0004] The current situation of common belt conveyors that occupy a lot of manpower and material resources restricts the improvement of conveyor operation time and transportation efficiency. The process of belt maintenance and replacement includes four main links: belt replacement, construction of vulcanization platform, joint production and vulcanization bonding. Among them, the vulcanization process requirements of the three links of belt replacement, joint production and vulcanization bonding cannot be changed. However, the process time can be shortened in the construction of vulcanization platform to directly produce a movable conveyor belt vulcanization platform. To this end, the technical problems solved by the present invention are: 1. Design and manufacture a movable conveyor belt vulcanization platform that can be put into use once and used multiple times. It can be quickly installed before vulcanization and quickly removed after vulcanization to facilitate the rapid hot vulcanization of the conveyor belt, thereby saving manpower and material resources, shortening the inspection and maintenance time of the conveyor belt, and improving the transportation efficiency of the conveyor; 2. The use of a movable conveyor belt vulcanization platform can eliminate safety hazards. Normally, the conveyor belt joint vulcanization work surface requires maintenance personnel to stand on a 1.8-meter-high rack to operate, which poses a safety hazard and can easily cause falls from heights. Now, operators can stand on the movable conveyor belt vulcanization platform to perform operations, which can ensure the safety of personnel; 3. The use of a movable conveyor belt vulcanizing platform can ensure the quality of the vulcanized joint and facilitate the centering and alignment of the conveyor belt joint. The six points at both ends of the joint are on the same straight line. After centering, there are belt clamps at both ends of the vulcanizing platform to prevent the central axis of the conveyor belt from shifting. After vulcanization, the conveyor belt will not deviate and can operate normally.

[0005] In order to solve the above problems, the present invention proposes a movable conveyor belt vulcanizing platform. Summary of the Invention

[0006] In order to solve the above problems, the present invention provides a movable conveyor belt vulcanizing platform. Through the movable conveyor belt vulcanizing platform, the vulcanizing platform can be quickly installed before vulcanization and quickly removed after vulcanization, which facilitates the rapid implementation of the hot vulcanization work of the conveyor belt and achieves the purpose of rapid vulcanization of the conveyor belt joints.

[0007] In order to achieve the above technical effects, the present invention is implemented through the following technical solutions: a movable conveyor belt vulcanization platform, including a chassis, a workbench, a safety guardrail, a lifting lug, a tape clamping and centering mechanism, an escalator, and a vulcanizing equipment. The chassis is installed on the frame of the conveyor belt, and a workbench is installed on the front and rear sides above the chassis. A detachable safety guardrail is installed around the workbench. The lifting lugs for lifting are welded to the left and right sides of the beam in the chassis or welded to the left and right sides of the workbench. The tape clamping and centering mechanism is installed in the middle of the workbench. The escalator is welded to the side of the workbench. The vulcanizing equipment is detachably installed in the middle of the chassis.

[0008] Preferably, the chassis further comprises horizontal beams, vertical beams and pillars, a plurality of longitudinal vertical beams are welded to the plurality of horizontal horizontal beams, and the pillars are divided into two groups, front and rear, which are respectively welded at the junction of the horizontal beams and the vertical beams.

[0009] Preferably, the height from the upper surface of the workbench to the bottom of the base frame does not exceed the combined height of the lower vulcanizing beam, the hydraulic 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° bevel according to the angle of the vulcanizer heating plate, and the upper surface of the workbench is marked with a center line extending to the front and rear sides.

[0011] Preferably, the safety guardrail 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 by a safety rope. A triangular warning tape is provided on the safety rope.

[0012] Preferably, the tape clamping and centering mechanism also includes a semicircular clamping seat, screw holes, bolts (not shown in the figure), and tape splints. The semicircular clamping seat is welded to the left and right sides of the middle of the workbench. A screw hole is provided in the center of the semicircular clamping seat. Screw holes are provided at both ends of the tape splint and are installed on the semicircular clamping seat by bolts to clamp the tape joint on the workbench. In this mechanism, the two tape splints can be used to clamp the tape by tightening the bolts.

[0013] The beneficial effects of the present invention are: 1. A movable conveyor belt vulcanization platform can simplify the operation process, shorten the vulcanization time, reduce the difficulty of work, improve work efficiency and comfort, facilitate disassembly and assembly, and move and transport quickly and flexibly; 2. Design and manufacture a movable vulcanization platform that can be used in multiple vulcanizations in the future. It can be invested once and used multiple times, reducing labor costs and improving production efficiency. Compared with temporary vulcanization platforms, a movable vulcanization platform is more flexible and superior, and it also saves time in setting up temporary platforms. 3. If there is no movable vulcanization platform, temporary welding to make the vulcanization platform will greatly increase the amount of welding and the welding time. When dismantling, cutting is required, and the maintenance process is cumbersome. It also increases the workload of equipment maintenance personnel. 4. Using a movable conveyor belt vulcanization platform can eliminate safety hazards. When vulcanizing the conveyor belt joints, maintenance workers need to stand on a 1.8-meter-high rack to operate, which poses a safety hazard and can easily cause falls from heights. Now, workers can stand on a movable conveyor belt vulcanization platform to operate, and this platform is also equipped with a safety guardrail device to ensure the safety of personnel and prevent falls from heights; 5. The use of a movable conveyor belt vulcanizing platform can ensure the quality of the vulcanized joint and facilitate the centering and alignment of the conveyor belt joint. The six points at both ends of the joint are on the same straight line. After centering, there are belt clamps at both ends of the vulcanizing platform to prevent the center axis of the conveyor belt from shifting. After vulcanization, it can ensure that the conveyor belt will not deviate and can operate normally. 6. The workbench can be used by maintenance personnel to make joints, strip wire ropes, and remove rubber. Although the conveyor maintenance site is limited, the workbench maximizes the use of limited space. The workbench also has the function of aligning and centering the joints at both ends, which facilitates the alignment of the conveyor belt joints and ensures that they are in the central axis position. 7. The safety guardrail device can be used to protect operators from falling accidentally when working or moving at heights. After it is made into a detachable safety guardrail device, it is convenient for installation, removal and transportation; 8. The lifting lugs are used during the installation and removal of the vulcanizing platform. The crane hook is connected to the lifting lugs to lift the equipment and install it in the designated location, shortening the replacement and maintenance time of the conveyor belt and improving production efficiency. 9. The tape splint is designed and fabricated in the center of the workbench. Both workbenches are welded with the tape splint. Two semicircular steel plates are welded to either side of the workbench's central axis, with bolt holes drilled in the center. Two 15# channel steels are also used, with bolt holes drilled at each end, to create the movable portion of the splint. Once the tape is centered, the two tape splints are used to clamp it securely, ensuring it does not shift, ensuring the vulcanization process is completed properly and without defects.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention. Example 1

[0016] like Figures 1 to 4 As shown, the prior art in this embodiment has the following problems: Based on the defects of the conveyor belt vulcanization process in the current technology, the inventors want to manufacture a movable conveyor belt vulcanization platform that can be used multiple times, shorten the inspection and maintenance time of the conveyor belt, improve the transportation efficiency of the conveyor, eliminate safety hazards, and facilitate the centering and alignment of the conveyor belt joints; Therefore, the inventor provides a movable conveyor belt vulcanizing platform, including a base frame 1, a workbench 2, a safety guardrail 3, a lifting lug 4, a tape clamping and centering mechanism, an escalator 5, and a vulcanizing equipment 6. The base frame 1 is installed on the frame 7 of the conveyor belt, and the workbench 2 is installed on the front and rear sides above the base frame 1. Removable safety guardrails 3 are installed around the workbench 2. The lifting lugs 4 for lifting are welded to the left and right sides of the crossbeam 8 in the base frame 1 or welded to the left and right sides of the workbench 2. The tape clamping and centering mechanism is installed in the middle of the workbench 2. The escalator 5 is welded to the side of the workbench 2. The vulcanizing equipment 6 is detachably installed in the middle of the base frame 1.

[0017] Furthermore, the chassis 1 also includes horizontal beams 8, vertical beams 9, and pillars 10. Several longitudinal vertical beams 9 are welded to the several horizontal horizontal beams 8, and the pillars 10 are divided into two groups, front and rear, which are respectively welded at the intersection of the horizontal beams 8 and the vertical beams 9.

[0018] Furthermore, the height from the upper surface of the workbench 2 to the bottom of the base frame 1 does not exceed the combined height of the lower vulcanizing beam 11 , the hydraulic plate, and the heat-insulating wooden board in the vulcanizing equipment 6 .

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

[0020] Furthermore, the safety guardrail 3 also includes a base (not shown in the figure), a support rod (not shown in the figure), 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 2, the support rod is inserted into the base, and the support rods are connected by a safety rope, and a triangular warning tape is provided on the safety rope.

[0021] Furthermore, the tape clamping and centering mechanism also includes a semicircular clamping seat 12, a screw hole 13, a bolt (not shown in the figure), and a tape splint 14. The semicircular clamping seat 12 is welded to the left and right sides of the middle of the workbench 2. The center of the semicircular clamping seat 12 is provided with a screw hole 13. The two ends of the tape splint 14 are provided with screw holes 13 and are installed on the semicircular clamping seat 12 by bolts for clamping the tape on the workbench 2. In this mechanism, the two tape splints 14 can be used to clamp the tape joint 15 by tightening the bolts. Example 2

[0022] According to the above embodiment, the inventors have carried out practical application, and the specific application is as follows: A movable vulcanizing platform is constructed by welding a horizontal beam 8 made of 14# channel steel, vertical beams 9 made of 12# channel steel, and supporting columns 10 to a workbench 2. During use, it is assembled with the upper and lower beams of a vulcanizer or other vulcanizing equipment 6. The channel steel type is determined by the vulcanizer and the number of overlaps between the joints. The workbench 2 is made of 5mm iron sheet, and the bevel angle of the workbench 2 is determined by the angle of the vulcanizer heating plate. When assembled with the vulcanizer equipment, the workbench 2 must be at least 67mm high. Multi-layer, multi-pass welding is used, with the horizontal beams 8 and vertical beams 9 welded together, creating a mesh structure that enhances strength and prevents deformation during use.

[0023] Crossbeam 8 is welded from five 7800mm long 14# channel steels. Other components are welded at 45° grooves where they meet crossbeam 8. Crossbeam 8 is then joined to vertical beams 9 and struts 10. By connecting vertical beams 9 and struts 10, crossbeam 8 enhances the overall stability and load-bearing capacity of the platform structure. Directly assembled with the conveyor frame 7, crossbeam 8 can be used to support, particularly the pallet vulcanizer, and withstand the longitudinal loads generated during operation, ensuring the platform's stability and safety during vulcanization operations. The vertical beams 9 are made of six 2000mm long 12# channel steels welded together and welded to the cross beams 8 to form a mesh structure base. As the supporting element of the vulcanization platform structure, the vertical beams 9 bear vertical loads and static and dynamic loads to ensure the safety of the vulcanization platform. The vertical beams 9 can provide lateral connections by connecting to other cross beams 8 or frames, thereby increasing the overall rigidity and stability of the vulcanization platform structure. The pillars 10 are welded from eight 670mm long 12# channel steel bars. Connected to the crossbeam 8, the work platform 2, and other components, they form a stable support system, effectively distributing the load above the vulcanization platform. Within the vulcanization platform structure, the pillars 10 play a crucial supporting role. They primarily transfer the weight of the work platform 2 to the frame 7, supporting the entire work platform 2 and providing a stable framework.

[0024] Workbench 2 is 2600mm long and 1900mm wide. Since it bears little load and doesn't carry any equipment, it can be welded using 5# angle steel to form a grid-like framework. 8mm patterned iron plates are then welded on top of the grid-like framework. Once the workbench 2 is complete, it's welded to the top of the support 10. Workbench 2 is then welded to both symmetrical ends of the vulcanization platform. This facilitates joint fabrication and centerline alignment for operators. Safety guardrails are made of galvanized pipes and welded at the four diagonal corners of the vulcanization platform. First, 10 cm DN25 galvanized pipes are welded to the four corners of the bottom. Then, 1.5 m DN20 galvanized pipes are inserted into the DN25 galvanized pipes in sequence. Binding hemp ropes and triangular warning tapes are installed between the galvanized pipes to make a detachable safety guardrail, which is convenient for installation, removal and transportation. Lifting lugs 4 are welded to crossbeam 8, two on each side, for a total of four. These lugs 4 provide attachment points for a crane or other lifting equipment, facilitating the smooth lifting and movement of the vulcanizing platform. During installation and removal, the platform is hoisted and installed in its designated location by attaching the lifting lugs 4 to the crane's hook.

[0025] The tape clamping and centering mechanism is designed and fabricated in the center of workbench 2. Tape clamps 14 are welded to both workbench 2. Two semicircular steel plates are welded to either side of the workbench 2's central axis, with bolt holes centered. Two 15# channel steels are also used, with bolt holes drilled at each end, to create the movable portion of the clamps. Once the tape is centered, the two tape clamps 14 securely clamp the tape, preventing it from shifting and ensuring proper, defect-free vulcanization. Then a ladder is welded on the outside of the vulcanization platform to facilitate personnel to go to and from get off work and for maintenance, eliminating the risk of injuries from falling from heights.

[0026] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0027] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution.
