Description

Technical Field

[0001] The utility model relates to the technical field of tensioning, in particular to a high-temperature zone heavy-load tensioning device. Background Art

[0002] The high temperature area heavy load tensioning device is a device used to maintain or adjust the tension of mechanical parts in a high temperature environment, thereby maintaining or adjusting the tension of chains, belt drives, cables, etc. Under high temperature and heavy load conditions, it maintains appropriate tension to prevent the material from expanding or contracting due to temperature changes, prevent the belt from slipping, or prevent the synchronous belt from jumping teeth or falling off and being dragged out.

[0003] Currently, most overload tensioning devices wind a chain or belt around a spring-loaded rotating wheel and perform the tightening operation through the swing of the spring. Due to the heavy weight of the sprocket, a large loss of electrical energy will be caused during the movement of the chain, and jamming may occur. Utility Model Content

[0006] Workbench; and

[0007] The tensioning structure includes a rotating wheel assembly and a chain assembly. The rotating wheel assembly is drivingly connected to the end surface of the workbench, the chain assembly is connected to the outer edge of the rotating wheel assembly, and the chain assembly is slidably connected to the workbench.

[0008] In one embodiment of the present application, the rotating wheel assembly comprises:

[0013] A guide wheel is located between the transmission chain and the workbench, and the guide wheel is threadedly connected to the bottom wall of the transmission chain.

[0014] In one embodiment of the present application, a slide rail is provided at the connection between the rotating wheel assembly and the workbench, and the rotating wheel assembly is slidably connected to the slide rail.

[0015] In one embodiment of the present application, a guide rail is provided on the side of the support platform facing the guide wheel.

[0016] In one embodiment of the present application, a tension block is threadedly connected to the side of the workbench facing away from the sprocket, and the tension block is elastically connected to the wall surface of the support platform.

[0017] The technical solution of the utility model is to arrange a tensioning structure on the end face of the workbench, wherein a rotating wheel assembly in the tensioning structure is driven to rotate to drive the movement of the chain, and the chain is slidably connected to the workbench, thereby ensuring that the tensioning process of the heavy-load tensioning device is carried out smoothly, avoiding the accumulation of the chain resulting in a low tensioning degree due to the excessive weight of the chain causing the movement of the chain to be not smooth enough.

[0028] To solve the problems in the background technology, such as Figure 1 to Figure 2 As shown, the utility model proposes a high-temperature zone heavy-load tensioning device, including a workbench 1 and a tensioning structure 2, the tensioning structure 2 includes a rotating wheel assembly 21 and a chain assembly 22, the rotating wheel assembly 21 is drivingly connected to the end face of the workbench 1, the chain assembly 22 is connected to the outer edge of the rotating wheel assembly 21, and the chain assembly 22 is slidably connected to the workbench 1.

[0029] It can be understood that the workbench 1 is the basic part of the device, which is used to support and install the tensioning structure 2. The workbench 1 is made of strong materials to withstand stress under high temperature and heavy load conditions; the tensioning structure 2 is the core part of the device, which is used to adjust and maintain the tension of the chain or mechanical parts; the wheel assembly 21 is connected to the end face of the workbench 1 and is responsible for transmitting power or motion. The wheel assembly 21 ensures reliable operation under high temperature and heavy load conditions, and the chain can be driven to rotate through the wheel assembly 21; the chain assembly 22 is connected to the outer edge of the wheel assembly 21 and is slidably connected to the workbench 1. The function of the chain assembly 22 is to transmit power and maintain tension. The chain assembly 22 is heavy, and the chain can pass through the hub on the end face of the workbench 1, thereby reducing the friction of the chain assembly 22 on the workbench 1, thereby ensuring the normal working process of the tensioning structure 2, making the tension adjustment of the chain smoother.

[0030] like Figure 2 As shown, in one embodiment of the present application, the rotating wheel 213 assembly includes a sprocket 211 and a driving member 212. A rotating wheel 213 is provided between the sprocket 211 and the workbench 1. The rotating wheel 213 is threadedly connected to the workbench 1. The driving member 212 is located on the side of the workbench 1 facing away from the sprocket 211. The sprocket 211 is drivingly connected to the driving member 212.

[0031] It can be understood that the sprocket 211 is a part of the rotating wheel 213 assembly. The sprocket 211 is located in the device and is used to cooperate with the chain assembly 22 to transmit power and control the tension of the chain. The rotating wheel 213 is located between the sprocket 211 and the workbench 1, and plays a role in supporting and guiding the sprocket 211. The rotating wheel 213 is connected to the workbench 1 through a thread. This connection method can assist the rotating wheel 213 in rotating and adjusting to adapt to different working requirements and tensioning conditions.

[0032] The rotating wheel 213 is connected to the workbench 1 by threads. This design allows fine-tuning of the position of the rotating wheel 213 to ensure the accuracy and stability of the tensioning system. The driving member 212 is arranged on the side of the workbench 1 facing away from the sprocket 211. The function of the driving member 212 is to provide power to drive the sprocket 211 to rotate. This layout enables the driving member 212 and the sprocket 211 to be connected through gears to transmit power. The sprocket 211 is driven to be connected to the driving member 212, and the operation of the sprocket 211 is directly controlled by the driving member 212. This ensures that the tensioning device can work reliably in a high temperature environment, while allowing the operator to accurately adjust the tension of the chain.

[0033] like Figure 2As shown, in one embodiment of the present application, the chain assembly 22 includes a transmission chain 221 and a guide wheel 222 , the transmission chain 221 is meshed with the sprocket 211 , the guide wheel 222 is located between the transmission chain 221 and the workbench 1 , and the guide wheel 222 is threadedly connected to the bottom wall of the transmission chain 221 .

[0034] It can be understood that the transmission chain 221 is meshed with the sprocket 211 and driven by the sprocket 211 to rotate the guide wheel 222, which is made of hard materials such as metal to ensure stable operation and long-term use under high temperature and heavy load environments; the angle, speed and tension of the transmission chain 221 are also precisely controlled by the driving member 212 and the sprocket 211; the guide wheel 222 is located between the transmission chain 221 and the workbench 1, and plays a role in assisting the movement of the chain. The material and design of the guide wheel 222 need to be suitable for long-term work in a high temperature environment, and the guide wheel 222 can be connected by threading. Fixed on the bottom wall of the transmission chain 221, this is conducive to adjusting the exact position of the guide wheel 222 to meet the needs of different working conditions; the guide wheel 222 and the bottom wall of the transmission chain 221 are connected by threads, and the height of the guide wheel 222 is adjusted by rotation, so as to finely modify the path or tension of the transmission chain 221, which is an effective way to accurately control the working performance of the sprocket 211 system; it ensures the smooth, precise and reliable operation of the entire system, can maintain stability in high temperature and heavy load applications, and through threaded connection, it can be fine-tuned according to different actual conditions.

[0035] like Figure 2 As shown, in one embodiment of the present application, a slide rail 11 is provided at the connection between the rotating wheel assembly 21 and the workbench 1 , and the rotating wheel assembly 21 is slidably connected to the slide rail 11 .

[0036] It can be understood that the slide rail 11 is configured as a long strip of metal or hard synthetic material track, and its main function is to guide and support the movement of the wheel assembly 21. The slide rail 11 is designed to be a straight or curved structure to adjust the wheel assembly 21. The sliding connection between the wheel assembly 21 and the slide rail 11 means that the wheel assembly 21 can move freely on the slide rail 11; this connection method can reduce friction, making the movement of the wheel assembly 21 smoother and more precise. The materials of these wheels are selected from wear-resistant and low-friction materials to reduce wear and improve efficiency. The connection between the guide rail 12 and the workbench 1 usually needs to be both stable and flexible so as to allow necessary movement and adjustment while maintaining overall stability. The cooperation between the slide rail 11 and the wheel assembly 21 makes the movement of the equipment smoother and more precise, while also simplifying structural design and maintenance work.

[0037] like Figure 2 As shown, in one embodiment of the present application, a guide rail 12 is provided on one side of the guide wheel 222 of the support table.

[0038] It can be understood that the guide wheel 222 is a wheel-shaped component used to guide or support the moving chain; the guide rail 12 is located on one side of the support table, adjacent to the guide wheel 222, which can limit the structure of the guide wheel 222 moving along a specific path, and can adjust the tension by moving. The existence of the guide rail 12 ensures that the guide wheel 222 can move smoothly and accurately along the set trajectory, thereby improving the efficiency and accuracy of the overall system; when the guide wheel 222 moves along the guide rail 12, the chain can be tensioned and adjusted laterally forward and backward, thereby ensuring the adjustability of the overall equipment.

[0039] like Figure 2 As shown, in one embodiment of the present application, a tension block 13 is threadedly connected to the side of the workbench 1 facing away from the sprocket 211, and the tension block 13 is elastically connected to the wall surface of the support platform.

[0040] It can be understood that the tensioning block 13 is arranged on the back of the workbench 1 and is fixed to the sprocket 211. The tensioning block 13 is attached to the wall of the workbench 1, and the tensioning block 13 is elastically connected to the workbench 1 through a spring. When the sprocket 211 moves, auxiliary tensioning can be performed by the gravity of the tensioning block 13, thereby ensuring the overall adjustability of the equipment.

[0041] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
