Description

Technical Field

[0001] This utility model relates to the field of cableway technology, and in particular to a tensioning device for the belt of a detachable cableway acceleration and deceleration device. Background Technology

[0002] In actual operation, the precise disengagement and engagement of the grip and cable in a detachable cableway relies heavily on the acceleration and deceleration device to accurately control the speed during these stages. This precise speed matching ensures synchronization between the grip and cable, guaranteeing a smooth and accurate disengagement and engagement. Because the acceleration and deceleration device is a crucial component for successful detachment, its actual operating condition directly determines the overall stability, safety, and smoothness of the detachable cableway, playing a vital role in its normal operation. Furthermore, the efficiency of the acceleration and deceleration device is highly correlated with the belt's working condition. Therefore, whether the belt tension meets operating standards and whether the actual wear is within a reasonable range are critical factors affecting the normal operation of the acceleration and deceleration device and the entire cableway detachment system, possessing equally important technical significance.

[0003] However, in the current equipment design and on-site operation and maintenance conditions, the belt of the acceleration and deceleration device has the practical problem of inconvenient replacement operation. Moreover, when the belt wears out naturally during long-term operation, the existing equipment structure cannot effectively adjust its tension, making it difficult to restore the working state of the belt to the standard requirements. This directly affects the speed control accuracy of the acceleration and deceleration device, and consequently has an adverse effect on the disengagement action of the cable clamp.

[0004] This maintenance challenge is particularly pronounced at the pulley of the detachable gripper. The pulley in this area is installed at an angle, which, due to the dual constraints of equipment installation space and overall structural layout, further compresses the working space for belt disassembly and replacement. This also significantly increases the complexity of the operation process, making belt replacement much more difficult than with conventional vertically arranged pulley structures. This causes great inconvenience to daily maintenance and troubleshooting on site.

[0034] This patent provides multiple parallel solutions; the different descriptions represent improved or parallel solutions based on a basic solution. Each solution has its own unique characteristics. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other. Fixing methods not described herein can be any type of fixing, such as threaded fixing, bolt fixing, or adhesive bonding.

[0035] Example 1: Referring to all the attached drawings; a tensioning device for the belt of a detachable cableway acceleration / deceleration device, characterized in that,

[0036] The tensioning device includes a bracket as a support structure 2, the support structure 2 includes a bottom wall 3, and head walls 4 on both sides of the bottom wall 3. The head walls 4 and the bottom wall 3 are connected to the side wall 11.

[0037] One or more movable holes 7 are arranged on the bottom wall 3;

[0038] The axle 8 passes through the movable hole 7, and a threaded slider 6 is arranged on the axle 8;

[0039] Bolt 5, which passes through head wall 4, passes through threaded hole of threaded slider 6;

[0040] When bolt 5 is rotated, the threaded slider 6 can move, thereby driving the axle 8 and the pulley to move as a whole. The substantial technical effect and its implementation process, i.e., the basic function and non-obvious aspects, are as follows:

[0041] In operation, detachable grip cableways mainly rely on acceleration and deceleration devices to achieve the speed of detachment and engagement of the grip, thereby achieving perfect detachment and engagement. Therefore, the operating status of the acceleration and deceleration devices is crucial to the operation of the detachable grip. Consequently, the tension and wear of the belts on the acceleration and deceleration devices are also critical.

[0042] However, the belt is currently inconvenient to replace, and it cannot be tensioned after it wears out.

[0043] In particular, the pulleys corresponding to the release grappling hooks are arranged at an angle, making it even more difficult to replace the belts once they wear out.

[0044] In contrast to the shortcomings of existing technologies, such as the inconvenience of replacing belts in acceleration and deceleration devices, and the oblique installation of pulleys in this area, which further compresses the working space for belt disassembly and replacement due to the dual limitations of equipment installation space and overall structural layout, the complexity of the operation process is also greatly increased. This makes belt replacement much more difficult than with conventional straight-lined pulley structures, causing great inconvenience to daily maintenance and troubleshooting. This patent innovatively and non-obviously designs the support structure 2 as an integral structure with a curved arc, and arranges the two pulleys symmetrically around the central axis of the support structure 2. Combined with the movable connection structure between the wheel axle 8 and the movable hole 7 on the bottom wall 3, it breaks the limitation of the working space imposed by the obliquely arranged pulleys. Furthermore, the guide movement design of the square threaded slider 6 against the bottom wall 3 simplifies the component adjustment process during belt disassembly. Sufficient working space can be freed up without additional disassembly of the main equipment, greatly reducing the operational complexity caused by the compression of working space and significantly improving the convenience of belt replacement, daily maintenance, and troubleshooting.

[0045] In contrast to the shortcomings of existing technologies, such as the inability of existing equipment structures to effectively adjust the tension of belts after natural wear during long-term operation, which makes it difficult to restore the belt's working state to the standard requirements and directly affects the speed control accuracy of the acceleration and deceleration device, thus adversely affecting the disengagement action of the belt clamp, this patent innovatively and non-obviously constructs a linkage adjustment structure with bolt 5, threaded slider 6, wheel axle 8, and moving hole 7. By rotating bolt 5, which passes through the threaded hole of threaded slider 6 through head wall 4, threaded slider 6 is driven to move directionally along bottom wall 3, thereby driving wheel axle 8 and its pulley to move along moving hole 7, achieving precise adjustment of belt tension. At the same time, locking nuts on both sides of threaded slider 6 are used to fix the adjusted position, ensuring the stability of belt tension and enabling the worn belt to quickly return to the standard working state, effectively ensuring the speed control accuracy of the acceleration and deceleration device and avoiding adverse effects on the disengagement action of the belt clamp.

[0046] Example 2: As a further improvement, parallel, or optional independent solution, the support structure 2 is an overall curved structure. The substantial technical effect and its implementation process, i.e., its basic function and non-obvious aspects, are as follows: the curved structure makes the wheel guide smoother.

[0047] Example 3: As a further improvement, parallel, or optional independent solution, the movable hole 7, the axle 8, and the corresponding pulley comprise two. The substantial technical effect and its implementation process, i.e., the basic function and non-obviousness, are as follows: to achieve the function of supporting the belt.

[0048] Example 4: As a further improvement, parallel, or optional independent solution, the two pulleys are pulley 9 and pulley 10.

[0049] Example 5: As a further improvement, parallel, or optional independent solution, the two pulleys are arranged symmetrically around the central axis of the support structure 2. The substantial technical effect and its implementation process, i.e., the basic function and non-obviousness, are as follows: symmetry makes the overall structure more stable under stress.

[0050] Example 6: As a further improvement, parallel, or optional independent solution, the threaded slider 6 has a cylindrical or square block structure. The substantial technical effect and its implementation process, i.e., its basic function and non-obviousness, are as follows: This structure prevents the threaded slider 6 from sliding.

[0051] Example 7: As a further improvement, parallel solution, or optional independent solution, the threaded slider 6 can be locked on both sides by locking nuts. The substantial technical effect and its implementation process, i.e., the basic function and non-obviousness, are as follows: to avoid the impact of shaking on the overall structure.

[0052] Innovatively, each of the above effects exists independently, yet a single structure can be used to combine the results.

[0053] It should be noted that the multiple modules in this patent are an integration of existing technology modules and do not involve any new modules. Even if some modules use programs, those programs are undoubtedly known programs.

[0054] It should be noted that the multiple solutions provided in this patent include their own basic solutions, which are independent of each other and do not restrict each other. However, they can also be combined with each other without conflict to achieve multiple effects.

[0055] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
