[0029] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0031] In the present invention, unless otherwise specified, directional words such as "up, down, top, bottom" are usually used with reference to the directions shown in the drawings, or with reference to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0032] like Figures 1 to 9 As shown, an embodiment of the present invention provides a chain inspection device for detecting a chain, comprising: a bracket 1, a top of which is provided with a support platform 11 set at a distance from the ground; a driving wheel 2, rotatably provided on the support platform 11, for contacting the chain 4 to drive the chain to move; a locking mechanism 3, movably provided on the bracket 1, having an avoidance position and a locking position, when the locking mechanism 3 is in the locking position, it engages with the chain 4 to fix the chain 4 relative to the bracket 1, and when the locking mechanism 3 is in the avoidance position, it is spaced apart from the chain 4 to avoid the chain.

[0033] The support platform of the chain inspection device provided by the embodiment of the utility model lifts the chain, avoids direct contact with the ground. The cooperation of the driving wheel and the locking mechanism ensures the stability of the chain during inspection and the accuracy of positioning. Effectively solve the technical problem that the chain is easily worn by the ground during inspection.

[0034] In the above embodiment, the support provides a stable structural foundation for the entire device, and the support platform at the top is kept a certain distance from the ground, avoiding direct contact of the chain with the ground and reducing wear and tear and scratches caused by dragging or turning during inspection. The driving wheel is rotatably arranged on the support platform and contacts and drives the chain. The arrangement of the driving wheel ensures that the chain can be smoothly driven without additional wear caused by friction with the ground, and the rotation of the driving wheel also ensures that each part of the chain can be evenly inspected. The locking mechanism is movably arranged on the support and has a avoiding position and a locking position. When in the locking position, the locking mechanism is engaged with the chain to ensure that the chain is fixed relative to the support, facilitating detailed inspection or polishing operation of a single chain link. When in the avoiding position, the locking mechanism is spaced apart from the chain to avoid hindering the smooth movement of the chain. This feature of the locking mechanism allows the chain to move smoothly when driven by the driving wheel without increasing friction due to the interference of the locking mechanism, thereby reducing wear and tear of the chain.

[0035] With this design, the chain inspection device can stably fix the chain and release it when needed, facilitating the installation and removal of the chain and improving detection efficiency. This device is particularly suitable for rapid chain detection on factory production lines and chain performance evaluation in repair workshops. In practical applications, this design can significantly reduce the preparation time before and after detection, improving production efficiency. For example, on the production line of textile machinery, rapid chain detection can timely detect chain wear and tear and looseness, avoid downtime and failure caused by chain problems, and ensure stable operation of the production line.

[0036] As Figure 4 , Figure 5As shown, specifically, there are multiple driving wheels 2, including a first driving wheel 21 and a second driving wheel 22, and the first driving wheel 21 and the second driving wheel 22 are respectively arranged at the two ends of the support platform 11 near the side of the bracket 1. By providing multiple driving wheels, the chain can move forward or backward during use, and at the same time, the load of the chain can be more evenly distributed, reducing the wear of the chain during the detection process and extending the service life of the chain. In the chain detection of large-scale mechanical equipment, this multi-wheel design is particularly critical and can ensure the accuracy and reliability of chain detection. In actual applications, this multi-wheel design can effectively reduce the wear rate of a single driving wheel, extend the service life of the driving wheel, and reduce the maintenance cost of the equipment. For example, in port loading and unloading equipment, the chain can be detected more smoothly through the joint action of multiple driving wheels, avoiding detection interruptions caused by damage to a single driving wheel, and ensuring the continuous operation of the equipment.

[0037] Specifically, the chain inspection device also includes a first drive device 51 and a second drive device 52. The first drive device 51 is connected to the first driving wheel 21 to drive the first driving wheel 21 to rotate, and the second drive device 52 is connected to the second driving wheel 22 to drive the second driving wheel 22 to rotate. The independent drive device can accurately control the rotational speed and torque of each driving wheel, which is suitable for detecting chains of different specifications and materials, thereby improving the versatility and adaptability of the device. In the chain detection of precision instruments and aerospace equipment, this independent drive design can meet the detection requirements of various chains. In practical applications, this independent drive design can more flexibly adjust the detection parameters of the chain, adapt to the detection of chains of different materials and specifications, and improve the accuracy and reliability of the detection. For example, in the chain detection of aerospace equipment, by accurately controlling the rotational speed and torque of the driving wheel, the fatigue and strength of the chain can be more accurately assessed, thereby ensuring the safe operation of the equipment.

[0038] like Figures 6 to 9As shown, specifically, the first drive device 51 and the second drive device 52 each include a drive motor 53, a main gear 54, a transmission chain 55, and a slave gear 56. The output shaft of the drive motor 53 is connected to the main gear 54, the transmission chain 55 is mounted on the main gear 54 and the slave gear 56, and the slave gear 56 is mounted on the driving wheel 2. The first drive device 51 and the second drive device 52 are both mounted on the support platform 11 of the bracket 1. The drive motor drives the main gear, which drives the transmission chain to rotate the slave gear, thereby driving the driving wheel to rotate. This gear transmission structure not only has high transmission efficiency, but also can achieve precise speed and torque control, ensuring the accuracy of chain detection. This high-precision transmission system is indispensable for chain detection of precision instruments and aerospace equipment. In practical applications, this gear transmission design can effectively improve the transmission efficiency of chain detection, while achieving more precise speed and torque control, improving the accuracy and reliability of detection. For example, in the chain detection of precision instruments, through the precise control of gear transmission, small changes in the chain, such as slight slack and wear of the chain, can be detected more accurately, providing an important basis for the maintenance of precision instruments.

[0039] Specifically, the chain inspection device also includes at least one driven wheel 6, which is positioned on the side of the bracket 1 and adjacent to the support platform 11. The chain 4 is mounted on at least a portion of the driven wheel 6 to drive the driven wheel 6 to rotate when the chain 4 moves. The arrangement of the driven wheel assists the movement of the chain, reduces the load on the driving wheel, and can monitor the operating status of the chain, such as chain slack and wear, to provide a basis for chain maintenance and replacement. In chain inspections of heavy machinery such as mining machinery and port loading and unloading equipment, this auxiliary wheel design can significantly improve inspection efficiency and safety. In practical applications, the auxiliary function of the driven wheel can significantly reduce the load on the driving wheel, reduce the wear rate of the driving wheel, and extend the service life of the driving wheel. Furthermore, by monitoring the operating status of the driven wheel, chain performance can be more accurately assessed, providing an important basis for chain maintenance and replacement. For example, in chain inspections of mining machinery, monitoring the driven wheel can promptly detect chain slack and wear, thus avoiding equipment failures and safety hazards caused by chain problems.

[0040] Specifically, the locking mechanism 3 is two and is respectively a first locking mechanism 3a and a second locking mechanism 3b, and the first locking mechanism 31 and the second locking mechanism 3b are symmetrically arranged on both sides of the bracket 1. The symmetrically arranged locking mechanism can provide more stable fixing effect, avoid the chain from shifting or twisting during detection, and ensure the accuracy of the detection result. In the automobile manufacturing, bicycle assembly and other industries, this symmetrical locking design can meet the efficient and accurate detection needs on the production line. In practical application, the symmetrically arranged locking mechanism can provide more stable fixing effect, avoid the chain from shifting or twisting during detection, and improve the accuracy and reliability of detection. For example, on the production line of automobile manufacturing, through the stable fixation of the symmetrical locking mechanism, the performance of the chain can be more accurately detected, and the production interruption and product quality problems caused by chain problems can be avoided.

[0041] Specifically, the locking mechanism 3 includes a telescopic rod 31, a first rotating plate 32 and a second rotating plate 33, the first rotating plate 32 and the second rotating plate 33 are rotationally connected, one end of the telescopic rod 31 is connected with the first rotating plate 32, the other end of the telescopic rod 31 is connected with the second rotating plate 33, the telescopic rod 31 is telescopically arranged to drive the first rotating plate 32 to open and close relative to the second rotating plate 33 to make the locking mechanism in the avoiding position and the locking position. During use, when the chain needs to be locked, the rotating plate is lowered to make the gap in the middle of the rotating plate clamping the chain, and after the inspection is completed, the chain is removed from the gap, and then the rotating plate is folded up. The combination design of the telescopic rod and the rotating plate not only has simple structure and convenient operation, but also can adapt to chains of different sizes, improving the flexibility and adaptability of the device. In the field detection of various chains, this design can quickly adapt to various working environments and improve the detection efficiency. In practical application, the combination design of the telescopic rod and the rotating plate not only facilitates operation, but also can adapt to chain detection of different sizes and types, improving the versatility and adaptability of the device. For example, in the field detection of construction sites, through the flexible combination of the telescopic rod and the rotating plate, the detection needs of various chains can be quickly adapted, improving the efficiency and flexibility of detection.

[0042] Specifically, the bottom of the support 1 is provided with a plurality of pulleys 7 for moving the support 1 in the horizontal direction, and the pulleys 7 are provided with brake members 71 corresponding to the pulleys 7 to lock or unlock the pulleys 7. The combination of the bottom pulleys and the brake members makes the whole device move conveniently and position accurately, not only suitable for indoor detection, but also able to meet the needs of outdoor on-site detection, greatly improving the flexibility and convenience of detection work. In construction sites, railway maintenance and other occasions, this mobile design can quickly reach the detection point, improving work efficiency. In practical application, the combination of the bottom pulleys and the brake members not only improves the mobility of the device, but also realizes accurate positioning, improving the efficiency and safety of detection. For example, in the process of railway maintenance, through the movement of the bottom pulleys, the detection point can be quickly reached, and through the locking of the brake members, the device can be accurately fixed, improving the efficiency and flexibility of detection.

[0043] Specifically, the depth of the groove along the radial direction of the driving wheel 2 is L, and L satisfies: 50mm≤L≤150mm. Reasonable groove depth design can ensure good contact between the chain and the driving wheel, avoid chain jumping or slipping phenomenon during detection, and ensure the stability and safety of the detection process. In the daily maintenance and inspection of the chain, this design can effectively improve the accuracy and reliability of the detection. In practical application, reasonable groove depth design can ensure good contact between the chain and the driving wheel, avoid chain jumping or slipping phenomenon during detection, and improve the accuracy and reliability of the detection. For example, in the daily maintenance and inspection of food processing equipment, through reasonable groove depth design, the performance of the chain can be detected more accurately, avoiding production interruption and product quality problems caused by chain problems.

[0044] Specifically, the width of the groove along the axial direction of the driving wheel 2 is d, and d satisfies: 40mm≤d≤120mm. The design of axial width considers the width range of the chain, ensures stable contact between the chain and the driving wheel, is suitable for chain detection of different widths, and improves the universality of the device. In the textile machinery, food processing equipment and other industries using chains, this width-adjustable design can meet the detection needs of various chains, improving the efficiency and accuracy of detection. In practical application, the design of axial width considers the width range of the chain, ensures stable contact between the chain and the driving wheel, and improves the universality and adaptability of the device. For example, in the chain detection of textile machinery, through the adjustment of the axial width, the detection of chains of different widths can be adapted, improving the universality and flexibility of detection.

[0045] In the above embodiment, by setting driving wheels with different depths and widths, the chain inspection device of the utility model can accommodate chains with diameters between 26mm and 48mm, making the chain inspection range of the utility model more extensive.

[0046] The method of using the chain inspection device of the utility model is as follows:

[0047] First, move the tower to the site where the chain is located and secure it with the brakes;

[0048] Lead the chain into the front drive wheel and the rear drive wheel in sequence through the wire rope or the guide chain;

[0049] During inspection, the chain is pushed forward by the front drive wheel, and the inspector stands at the position where the rear bracket is located to inspect the chain;

[0050] When the chain needs to be polished, lower the front bracket, clamp the chain to be polished, and polish it at the position where the front bracket is located;

[0051] After the chain link is inspected and polished, the chain is pushed forward by the drive wheel to complete the inspection of the next link;

[0052] When it is necessary to re-inspect or rework the chain link that has been inspected, the chain can be moved in the opposite direction through the rear drive wheel;

[0053] After the inspection is completed, the chain is unloaded, the brake is released, and the tower is moved to the next inspection site;

[0054] The application of the technical solution of the utility model has the following beneficial effects:

[0055] The design of this chain inspection device, through the coordination of a movable locking mechanism and a driving pulley, enables stable detection and movement of the chain, improving detection efficiency and accuracy. Furthermore, the provision of a first drive mechanism and a second drive mechanism allows for independent control of the rotation of the two driving pulleys, providing a more uniform driving force for the chain and ensuring a smooth detection process. Furthermore, the combination of a bottom pulley and a brake member makes the entire device easy to move and accurately positioned, significantly enhancing the user experience and flexibility of the detection process. The rational structural design of this device not only effectively improves the convenience and reliability of chain detection, but also significantly reduces the labor intensity of the operator, thus possessing significant practical value and broad application prospects.
