Description

Technical Field

[0001] This utility model relates to the field of connecting ring technology, and in particular to a device for testing the tensile strength of connecting rings. Background Technology

[0002] Shackles, also known as connecting rings, are commonly used connecting devices in mechanical engineering. Common engineering shackles include European-style large bow shackles, European-style large DEE shackles, round-head shackles, square-head shackles, and D-shaped shackles, among others. In rescue operations, shackles are usually called connecting rings and are essential connecting devices between wire ropes, between wire ropes and the vehicle body, between wire ropes and pulleys, and between rigid traction frames and the vehicle body. The form of the connecting ring varies depending on its application.

[0003] For example, CN216484319U discloses a tensile strength testing device for mining connecting rings, including a power box, a track frame, a tensioning frame, and a connecting belt. In this device, the connecting ring is fitted onto the tensioning frame, and the inner side of the connecting ring is respectively inserted into two tensioning grooves. The drive motor is started, causing the rotating shaft to rotate. Simultaneously, the rotating shaft drives the transmission wheel to rotate, and the connecting belt gradually wraps around the transmission wheel. The tensioning rod is stretched by the connecting belt, and the track plates at both ends of the tensioning rod move within the track grooves. The two tensioning rods move in opposite directions on the track grooves via the track plates. The movement of the tensioning rods causes the tensioning grooves to move, and simultaneously, the connecting ring within the tensioning groove is stretched by the tensioning frame during the movement. This device tests the tensile strength of the connecting ring. After the connecting rings are produced, this device can perform sampling tests to ensure that the connecting rings meet the usage requirements.

[0004] However, in the existing technology, when testing the pull-out strength of the connecting ring, it is usually necessary to use a clamp to fix the connecting ring first. However, the existing clamps can usually only clamp and fix connecting rings of a single shape and size, which limits the practicality of the device and the testing efficiency to a certain extent. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing clamps in the prior art can usually only clamp and fix connecting rings of a single shape and size, which affects the practicality and detection efficiency of the device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a tensile strength testing device for a connecting ring, comprising a main body, on both sides of the upper surface of the main body symmetrically provided with disassembly and assembly grooves, a moving groove provided at the center of the upper surface of the main body, and the disassembly and assembly grooves communicating with the moving groove, supports fixedly provided at the four corners of the lower surface of the main body, a protective mechanism provided on one side of the outer surface of the main body, a merging component provided on the side wall of the moving groove, a moving mechanism provided in the inner cavity of the main body, a moving plate provided on the surface of the moving mechanism, a quick-change mechanism provided on the outer wall of the moving plate, the quick-change mechanism including a slide groove, the slide groove being symmetrically provided on the outer wall of the moving plate, a slide rod fixedly provided in the inner cavity of the slide groove, a slider slidably provided on the surface of the slide rod, a first spring elastically provided between the lower surface of the slider and the inner bottom wall of the slide groove, a limit plate fixedly provided on the outer surface of the slider, a push-pull plate fixedly provided on the outer surface of the limit plate, and a clamp slidably provided on the upper surface of the moving plate.

[0007] In a preferred embodiment, the moving mechanism includes a second lead screw, which is driven at the center of the main body cavity, and guide rods are symmetrically fixed on both sides of the main body cavity.

[0008] In a preferred embodiment, a movable plate is symmetrically driven on the surface of the second lead screw, and the two ends of the movable plate are slidably connected to the guide rod. A second motor is fixedly installed on the outer wall of the main body, and the second motor is drivenly connected to one end of the second lead screw.

[0009] In a preferred embodiment, the protective mechanism includes a mounting groove, which is formed on one side of the outer surface of the main body. A first lead screw is drivenly installed in the inner cavity of the mounting groove. A first motor is fixedly installed on the outer wall of the main body at a corresponding position to the first lead screw, and the output end of the first motor is drivenly connected to one end of the first lead screw on the outside.

[0010] In a preferred embodiment, a movable frame is symmetrically mounted on the surface of the first lead screw, and a protective shell is fixedly mounted on the inner side of the movable frame, with the lower surface of the protective shell fitting against the upper surface of the main body.

[0011] In a preferred embodiment, the merging component includes a movable cavity, which is symmetrically opened on the inner wall of the moving groove, and a plurality of second springs are fixedly disposed on the inner wall of the movable cavity.

[0012] In a preferred embodiment, a movable plate is elastically provided at one end of the second spring, and a pad is fixedly provided at the end of the movable plate away from the second spring, and the movable plate is slidably connected to the movable cavity.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] This utility model, by setting up a quick-change mechanism, allows for the testing of pull-out strength of connecting rings of different sizes and shapes. By first pushing down the push-pull plate, the push-pull plate moves the limiting plate downward, and the limiting plate moves the slider along the guide groove and slide rod, compressing the first spring. This allows the fixture to be removed and replaced with fixtures of different sizes and shapes. Then, the first spring is reset and moved upward to limit and fix the fixture. This makes disassembly and assembly convenient and easy to use, improving the practicality and testing efficiency of the device.

[0015] This invention, by setting up a merging component, after clamping and fixing connecting rings of different shapes and sizes, pushes the pad outward. The pad drives the movable plate to slide along the movable cavity and squeeze the second spring. When the fixture enters the moving groove, the second spring rebounds and resets, causing the movable plate and the pad to move towards each other, so that the pad fits against the surface of the fixture of different shapes and sizes, preventing the connecting ring from falling off, facilitating subsequent pull-out strength testing, and further improving the practicality and testing efficiency of the device.

[0016] This utility model incorporates a protective mechanism. Once the connecting ring is fixed, the first motor drives the first lead screw to rotate, which in turn drives the movable frame to move towards each other along the mounting groove. The movable frame, in turn, causes the protective shells to move closer together, preventing the connecting ring from flying out and causing safety hazards when it breaks, thus improving the safety of the device.

A slider 16 is slidably provided. A first spring 17 is elastically provided between the lower surface of the slider 16 and the inner bottom wall of the slide groove 14. A limit plate 18 is fixedly provided on the outer surface of the slider 16. A push-pull plate 19 is fixedly provided on the outer surface of the limit plate 18. A clamp 13 is slidably provided on the upper part of the moving plate 12. When testing the pull-out strength of connecting rings of different sizes and shapes, the push-pull plate 19 is pushed down first. The push-pull plate 19 drives the limit plate 18 to move down. The limit plate 18 drives the slider 16 to slide along the slide groove 14 and the guide rod 15 and compress the first spring 17. The clamp 13 is then removed and replaced with a clamp 13 of different sizes and shapes. The clamp 13 is then limited and fixed by the return and upward movement of the first spring 17. The assembly and disassembly are convenient and the use is easy.

[0025] like Figure 1-4 As shown, the moving mechanism includes a second lead screw 10, which is driven and located at the center of the inner cavity of the main body 1. Guide rods 11 are symmetrically fixed on both sides of the inner cavity of the main body 1. Moving plates 12 are symmetrically driven and connected to the surface of the second lead screw 10, and both ends of the moving plates 12 are slidably connected to the guide rods 11. A second motor is fixedly installed on the outer wall of the main body 1, and the second motor is driven and connected to one end of the second lead screw 10. When the second motor is started, the second motor drives the second lead screw 10 to rotate. The second lead screw 10 drives the clamp 13 to move towards each other through the moving plates 12, and the moving plates 12 slide along the guide rods 11 to ensure the stable operation of the pull-out strength test of the connecting ring.

[0026] like Figure 1-4As shown, the protective mechanism includes a mounting groove 5, which is located on one side of the outer surface of the main body 1. A first lead screw 6 is driven through the inner cavity of the mounting groove 5. A first motor 9 is fixedly installed on the outer wall of the main body 1 at a corresponding position to the first lead screw 6, and the output end of the first motor 9 is drivenly connected to one end of the first lead screw 6. A movable frame 7 is symmetrically driven through the surface of the first lead screw 6. A protective shell 8 is fixedly installed on the inner side of the movable frame 7, and the lower surface of the protective shell 8 is in contact with the upper surface of the main body 1. After the connecting ring is fixed, the first motor 9 drives the first lead screw 6 to rotate, and the first lead screw 6 drives the movable frame 7 to move towards each other along the mounting groove 5. The movable frame 7 drives the protective shell 8 to move closer together, so as to prevent the connecting ring from flying out and causing safety hazards when it breaks.

[0027] like Figure 1-4 As shown, the merging component includes a movable cavity 20, which is symmetrically opened on the inner wall of the moving groove 4. Several second springs 21 are fixedly installed on the inner wall of the movable cavity 20. A movable plate 22 is elastically installed at one end of the second spring 21. A pad 23 is fixedly installed at the end of the movable plate 22 away from the second spring 21. The movable plate 22 is slidably connected to the movable cavity 20. After clamping and fixing connecting rings of different shapes and sizes, the pad 23 is pushed outward. The pad 23 drives the movable plate 22 to slide along the movable cavity 20 and squeeze the second springs 21. When the clamp 13 enters the moving groove 4, the second spring 21 rebounds and resets, causing the movable plate 22 and the pad 23 to move towards each other, so that the pad 23 fits against the surface of the clamp 13 of different shapes and sizes, preventing the connecting rings from falling off and facilitating subsequent pull-out strength testing.

[0028] Working principle: In use, first, different clamps 13 are replaced according to the shape, size, and dimensions of the connecting ring. During replacement, the push-pull plate 19 is pushed down, causing the limiting plate 18 to move downwards. The limiting plate 18 then causes the slider 16 to slide along the guide rail 14 and slide rod 15, compressing the first spring 17. The clamp 13 is then removed and replaced with a clamp 13 of different size and shape. The clamp 13 is then fixed in place by the return movement of the first spring 17. Disassembly and assembly are convenient, and it is easy to use. Pushing the pad 23 outwards causes the movable plate 22 to slide along the movable cavity 20, squeezing the second spring 21. When the clamp 13 enters the moving groove 4, the second spring 21 rebounds and resets, causing the movable plate 22 and pad 23 to move together. The device moves to allow the pad 23 to fit against the surface of the clamps 13 of different shapes and sizes, preventing the connecting ring from falling off and facilitating subsequent pull-out strength testing. Before the pull-out strength test, the first motor 9 drives the first lead screw 6 to rotate, and the first lead screw 6 drives the moving frame 7 to move towards each other along the mounting groove 5. The moving frame 7 also drives the protective shells 8 to move closer together to prevent the connecting ring from flying out and causing safety hazards if it breaks. Then, the second motor is started, and the second motor drives the second lead screw 10 to rotate. The second lead screw 10 drives the clamps 13 to move towards each other through the moving plate 12. The moving plate 12 slides along the guide rod 11 to ensure the stable operation of the connecting ring pull-out strength test. The overall structure is simple, the operation is convenient, and it is suitable for large-scale promotion.

Any person skilled in the art may make changes or equivalent variations to the above-disclosed technical content and apply them to other fields. However, any simple modifications, equivalent variations and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
