Description

Technical Field

[0001] The utility model relates to the technical field of drag chain detection, in particular to a detection frame for damaged joints of a drag chain. Background Art

[0002] When a drag chain works under load for a long time, some joints will wear out, causing the entire drag chain to sag, which in turn affects the stability and safety of equipment operation.

[0003] Replacing worn joints is a necessary maintenance step. The general steps for replacing worn joints include: determining the drag chain model and the specific location of the worn joint; using the appropriate tools to remove the damaged joint and install the new joint into the drag chain; and inspecting and debugging the updated drag chain to ensure smooth operation.

[0004] There are two main ways to determine the specific location of worn joints: one is to inspect the entire chain for obvious signs of wear, such as scratches, deformed, or broken joints; the other is to use specialized tools to precisely measure the joint's size, shape, and surface roughness, even detecting internal defects that are difficult to see with the naked eye, to determine the extent of the joint damage. The former relies on manual visual inspection or empirical judgment, which lacks accuracy and efficiency, while the latter relies on specialized tools, which are expensive and offer accurate measurements but low efficiency.

[0005] Therefore, it is necessary to improve the existing technology and design a detection device that can more efficiently determine the damaged joints of the drag chain so that they can be replaced. Utility Model Content

[0006] The utility model provides a detection frame for damaged joints of a drag chain, which is used to solve the above problems.

[0007] A technical solution adopted by the utility model is to provide a detection frame for damaged joints of a drag chain, comprising: a bottom plate and a detection plate, wherein the detection plate is vertically arranged on the bottom plate and is used to place the drag chain;

[0008] The test plate is provided with evenly distributed vertical embedding grooves for cooperating with the embedding parts to fix specific joints on the drag chain. This not only allows the drag chain to be hung on the test plate, but also provides stable support for the drag chain below when replacing damaged joints.

[0009] A vertically movable caliper is provided on the left side of the detection plate. The normal height range is marked on the caliper, which represents the normal total height of two adjacent joints of the drag chain in a drooping state. It is used to compare with the total height of any adjacent joints of the drag chain in a drooping state to determine whether the drag chain joint is damaged.

[0010] Furthermore, a vertical guide rail is provided on the detection plate, and the caliper is slidably provided on the vertical guide rail through a slider, and has a locking device that can lock the caliper at any position of the vertical guide rail.

[0011] Furthermore, the embedment includes an L-shaped plate, a screw and a nut. The upper end of the L-shaped plate is provided with a through hole for the screw to pass through. When fixing the drag chain on the detection plate, the lower end of the L-shaped plate passes through the bottom of the first joint and is inserted into the embedment groove. The screw passes through the through hole and is inserted into the embedment groove above. The embedment is locked with a nut on the back of the detection plate.

[0012] Furthermore, the caliper has a fixed benchmark and a movable benchmark. The fixed benchmark is set at the top of the caliper and represents the starting position of height measurement. The movable benchmark can be adjusted up and down to meet the detection requirements of drag chains of different specifications.

[0013] Furthermore, the right end of the fixed pole is in the shape of an arrow, which is used to align the upper end of the joint, and the right end of the movable pole is in the shape of a square, which represents a normal height range.

[0014] The beneficial effects of the detection frame for damaged joints of a drag chain of the utility model are:

[0015] 1. A vertical inspection frame with a vertically movable caliper is designed. The weight of the drag chain and the normal total height of adjacent joints of the drag chain under deadweight are used to determine whether the corresponding joints are damaged. This enables quantitative detection of damage to the drag chain joints, improving the accuracy, reliability and efficiency of the detection.

[0016] 2. The design of the embedding groove and the embedding piece can effectively fix the drag chain to the detection plate. At the same time, it simplifies the removal and installation process of damaged joints, significantly shortens maintenance time and reduces labor costs. BRIEF DESCRIPTION OF THE DRAWINGS

They cannot indicate or imply that the components or elements referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0024] See also Figures 1 to 4 The first embodiment of the present invention provides a detection frame for damaged joints of a drag chain, comprising:

[0025] The bottom plate 1 and the detection plate 2, the detection plate 2 is vertically arranged on the bottom plate 1, and is used to place the drag chain 5;

[0026] The test plate 2 is provided with evenly distributed vertical embedding grooves for cooperating with the embedding parts 3 to fix specific joints on the drag chain 5. This not only allows the drag chain 5 to be hung on the test plate 2, but also provides stable support for the drag chain 5 below when replacing damaged joints.

[0027] A vertical guide rail 21 is provided on the left side of the detection plate 2. A caliper 4 is slidably provided on the vertical guide rail 21 via a slider. The caliper 4 is marked with a normal height range, which represents the normal total height of two adjacent joints of the drag chain 5 in a drooping state. The caliper 4 is used to compare the total height of any adjacent joint of the drag chain 5 in a drooping state to determine whether the joint of the drag chain 5 is damaged.

[0028] The caliper 4 has a locking device, which can lock the caliper 4 at any position of the vertical guide rail 21.

[0029] Specifically, the locking mechanism of the locking device is mechanical locking, which can adopt a locking screw or a clamping structure such as a clamp or a buckle.

[0030] The insert 3 includes an L-shaped plate 31, a screw 32 and a nut 33. A through hole is provided at the upper end of the L-shaped plate 31. When fixing the drag chain 5 on the detection plate 2, the lower end of the L-shaped plate 31 passes through the bottom of the first joint and is inserted into the embedding groove. The screw 32 passes through the through hole and is inserted into the embedding groove above. The insert 3 is locked with a nut 33 on the back of the detection plate 2. Two inserts 3 can be used to firmly fix the drag chain 5 on the detection plate 2.

[0031] Specifically, using the L-shaped plate 31 alone can also be used to stabilize the lower end of the drag chain 5 and play a guiding role. The two L-shaped plates 31 are embedded in the embedding groove corresponding to a joint and moved to both sides until they touch the inner edge of the joint, so that the drag chain 5 will not shake left and right, which is beneficial to the detection accuracy.

[0032] The caliper 4 has a fixed benchmark 41 and a movable benchmark 42. The fixed benchmark 41 is set at the top of the caliper 4, representing the starting position of the height measurement. Its right end is in the shape of an arrow, which is used to align the upper end of the joint. The movable benchmark 42 can be adjusted up and down to adapt to the detection requirements of drag chains 5 of different specifications. Its right end is a square, representing the normal height range.

[0033] Specifically, a vertical slide groove is provided on the caliper 4, and the inner surface of the slide groove has a tiny concave and convex texture to increase friction. A second slider that cooperates with the slide groove is provided on the back of the movable benchmark 42. The second slider is made of a material with a high friction coefficient such as rubber or silicone. The movable benchmark 42 can move up and down in the slide groove and stabilize at any position.

[0034] In other embodiments of the present invention, in order to more conveniently complete the fixation of the drag chain, a storage box and a cable fixing clamp are also provided on one side of the detection frame. The storage box is used to store various parts of the embedded parts, and the cable fixing clamp is used to clamp the cable part taken out of the drag chain.
