Description

Technical Field

[0001] This utility model relates to the field of fastener testing technology, and in particular to a testing device for fasteners used in ring-lock steel pipe scaffolding. Background Technology

[0002] Scaffolding couplers are core load-bearing connectors used in construction, bridge engineering, and other scenarios to connect the uprights, horizontal bars, and diagonal braces of steel pipe scaffolding. They transmit loads and restrict the relative displacement of members through mechanical locking, and are key components to ensure the overall stability and safety of scaffolding. They directly affect the safety of the construction process. The anti-slip performance, anti-damage performance, and locking reliability of the couplers directly affect the overall stability of the scaffolding. Once there are quality defects, it is easy to cause members to slip, joints to loosen, or even scaffolding collapse accidents, resulting in casualties and property damage. The detection device accurately identifies unqualified couplers by simulating the load action under actual working conditions, preventing inferior products from entering the construction site from the source, and providing a rigid guarantee for the life safety of construction workers.

[0003] The testing device used for ringlock steel pipe scaffolding couplers can only measure torque at a single point and cannot correlate it with the stress performance of the coupler under actual working conditions. The test results have limited reference value and cannot achieve linkage data recording of torsion angle, slippage and torque, which does not conform to the stress scenario in actual use. Utility Model Content

[0004] To address the issue that testing devices for ringlock steel pipe scaffolding couplers can only measure torque at a single point and cannot correlate it with the stress performance of the couplers under actual working conditions, this utility model provides a testing device for ringlock steel pipe scaffolding couplers, aiming to improve the problems in the existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: including a sliding amount detection mechanism and a torsion mechanism; The torsion mechanism is mounted on the surface of the sliding amount detection mechanism; The torsion mechanism includes a sliding component, a rotating component, and a driving component; The surface of the sliding component is in contact with the surface of the sliding amount detection mechanism. A rotating component is mounted on the surface of the sliding component, and a driving component is provided on the side of the rotating component.

[0006] The above technical solution describes a device primarily composed of two parts: a sliding amount detection mechanism and a torsion mechanism. The torsion mechanism is securely connected to the surface of the sliding amount detection mechanism via a mounting interface. More specifically, the torsion mechanism contains three key components: a sliding component, a rotating component, and a driving component. Structurally, the bottom surface of the sliding component is in direct contact with the upper surface of the sliding amount detection mechanism to ensure accurate motion transmission. A rotating component is mounted on the upper surface of the sliding component to achieve the required rotational motion. A driving component is also located on one side of the rotating component, providing power and motion control for the entire torsion mechanism.

[0007] As a further description of the above technical solution: the sliding amount detection mechanism includes a base component, which is installed at the bottom of the torsion mechanism, and a compression component is provided on the top of the base component.

[0008] The above technical solution involves a sliding amount detection mechanism comprising a basic structural component, referred to as the base component. This base component is fixedly connected to the lower end of the torsion mechanism, ensuring the stability and measurement accuracy of the overall structure. A dedicated compression component is designed on the upper surface of the base component. This component is used for real-time monitoring and data acquisition of the sliding amount during torsion, thereby improving the system's responsiveness and control accuracy. As a further description of the above technical solution: the base components include a mounting bracket, a vertical plate, a base plate, an adjustment push rod, a reinforcing plate, and a fixing block; The mounting bracket is positioned on top of the torsion mechanism; The outer surface of the mounting frame is fixedly connected to a vertical plate and a fixing block. The vertical plate is located inside the fixing block. A frame rod is fixedly connected to the inner side of the vertical plate. An anti-collision pad is fixedly connected to the outer surface of the vertical plate. A reinforcing plate is fixedly connected to the outer surface of the vertical plate. The outer surface of the reinforcing plate is fixed to the top of the mounting frame. A base plate is fixedly connected to the bottom of the mounting frame. A sliding groove is opened on the surface of the base plate. An adjustment push rod is fixedly connected to the inner wall of the mounting frame.

[0009] Through the above technical solution: the sliding amount detection mechanism includes a basic structural component, which is called the base component. The base component is tightly connected to the lower end of the torsion mechanism by a fixed installation method to ensure the stability of the overall structure and the measurement accuracy. On the upper surface of the base component, a special compression component is designed. This component is used to monitor and collect data on the sliding amount in real time during the torsion process, thereby improving the system's response capability and control accuracy.

[0010] As a further description of the above technical solution: the compression component includes a pressing push rod, an end ring, a pressing block, a support rod, a buffer ring, and a cone block; The clamping push rod is located at the top of the mounting bracket; The outer surface of the pressing push rod is fixed to the inner wall of the fixed block. An end ring is fixedly connected to the end of the pressing push rod. A pressure block is movably connected to the outer surface of the end ring. A support rod is fixedly connected to the side of the pressure block away from the end ring. The outer surface of the support rod slides against the inner wall of the upright plate. A cone block is fixedly connected to the end of the support rod. A buffer ring is fixedly connected to the outer surface of the cone block. The inner walls of the cone block and the buffer ring slide against the outer surface of the frame rod.

[0011] The above technical solution utilizes a compression component primarily composed of several parts, including a pressing push rod, an end ring, a pressure block, a support rod, a buffer ring, and a cone. These components work together to achieve the stability and functionality of the overall structure. The pressing push rod is precisely positioned at the top of the mounting frame, its outer surface tightly fixed to the inner wall of the fixed block, ensuring that the push rod will not shift or loosen under load. An end ring is fixedly connected to the end of the pressing push rod, serving as a connecting hub. Its outer surface engages with the pressure block in a movable manner, allowing the pressure block to adjust its position within a certain range. A support rod is fixedly connected to the side of the pressure block away from the end ring. The outer surface of the support rod maintains sliding contact with the inner wall of the upright plate, allowing the support rod to move smoothly along the upright plate while transmitting and dispersing external pressure. A cone is further fixedly connected to the end of the support rod, and a buffer ring is fitted to the outer surface of the cone. This buffer ring effectively absorbs and mitigates the impact and vibration generated during movement. The inner walls of the cone and the buffer ring slide against the outer surface of the frame rod.

[0012] As a further description of the above technical solution: the sliding component includes a displacement plate; The outer surface of the displacement plate slides against the outer surface of the mounting bracket, and the outer surface of the displacement plate slides against the outer surface of the base plate; The surface of the displacement plate is provided with a sliding key, the outer surface of which slides against the inner wall of the groove. An expansion block is fixedly connected to the outer surface of the displacement plate, and the outer surface of the expansion block is fixed to the end of the adjusting push rod.

[0013] Through the above technical solution: As a further description of the above technical solution: the rotating component includes a support frame, a rotating shaft, a rotating ring, a worm gear block, a frame, a round rod, and a positioning block; The support frame is located on the side of the mounting bracket; The outer surface of the support frame is fixed to the outer surface of the displacement plate. The inner wall of the support frame is rotatably connected to a rotating shaft. The outer surface of the rotating shaft is fixedly connected to a worm gear block. The outer surface of the worm gear block is fixedly connected to a rotating ring. The outer surface of the rotating ring rotates with the inner wall of the support frame. The end of the rotating shaft is fixedly connected to a frame. The inner wall of the frame is fixedly connected to a round rod. The outer surface of the frame rotates with the outer surface of the positioning block.

[0014] The above technical solution involves a sliding component primarily composed of a displacement plate. This displacement plate forms a sliding fit with multiple components to achieve precise position adjustment. Specifically, the outer surface of the displacement plate maintains sliding contact with the outer surface of the mounting bracket, creating relative movement between them, thus allowing the displacement plate to move within a certain range. Simultaneously, the outer surface of the displacement plate also slides against the outer surface of the base plate. This design further enhances the stability and guidance of the displacement plate during movement, ensuring smooth operation even under complex working conditions.

[0015] In addition, a sliding key is provided on the surface of the displacement plate. The outer surface of the sliding key fits tightly with the inner wall of the sliding groove to form a sliding pair, allowing the displacement plate to move smoothly along a predetermined path and effectively transmit force and motion. An expansion block is also fixedly connected to the outer surface of the displacement plate. The outer surface of the expansion block is fixed to the end of the adjusting push rod. Through this connection method, the adjusting push rod can drive the displacement plate to adjust its position. The expansion block plays a role in enhancing the connection strength and transmitting thrust during this process, ensuring that the entire sliding component responds quickly and positions accurately during operation.

[0016] As a further description of the above technical solution: the drive component includes a housing, a drive motor, a transmission shaft, and a worm gear; A drive motor is fixedly connected to the inner wall of the housing, a drive shaft is fixedly connected to the end of the drive motor, and a worm gear is fixedly connected to the outer surface of the drive shaft.

[0017] The above technical solution involves a drive component primarily consisting of a housing, a drive motor, a transmission shaft, and a worm gear. The housing serves as a crucial support and protective structure, with the drive motor securely mounted on its inner wall using bolts or other fasteners to ensure stability during operation. The output end of the drive motor is fixedly connected to one end of the transmission shaft via a coupling or direct connection, thereby transmitting the motor's rotational power to the transmission shaft. The outer surface of the transmission shaft is precision-machined and fixedly connected to the worm gear via a key connection or interference fit, ensuring efficient and reliable torque transmission to the worm gear, which then drives subsequent mechanical components to complete their corresponding actions. The design of the entire drive component fully considers structural compactness, transmission reliability, and long-term operational durability.

[0018] As a further description of the above technical solution: the outer surface of the cover box is fixed to the outer surface of the displacement plate, the outer surface of the worm gear meshes with the outer surface of the worm wheel block, and the outer surface of the transmission shaft rotates with the inner wall of the displacement plate.

[0019] Through the above technical solution: the outer surface of the cover box and the outer surface of the displacement plate are firmly connected by fasteners to ensure that the two remain relatively fixed during movement; the outer surface of the worm gear and the outer surface of the worm wheel block are tightly meshed through precise tooth profile matching, thereby effectively transmitting rotational motion and torque; the outer surface of the transmission shaft and the inner wall of the displacement plate are relatively rotated through bearings or sliding fits to ensure smooth and flexible transmission process.

[0020] This utility model has the following beneficial effects: 1. In this utility model, by accurately simulating the actual installation scenario of ring-lock couplers in scaffolding construction, the couplers are installed on the simulated uprights and horizontal bars of the frame and round bars, rather than the clamping method of traditional general equipment. This ensures that the stress state of the couplers during testing is highly consistent with that during actual use, avoiding the disconnect between the test results and the actual project. During the application of torsional force, the torsional deformation angle of the couplers can be read in real time, allowing for a direct judgment of the torsional resistance. At the same time, a stable thrust is applied along the frame direction, accurately detecting the amount of slippage of the couplers under force. This solves the problem that traditional digital torque wrenches can only measure torque and have poor adaptability to general testing machine scenarios.

[0021] 2. In this utility model, the entire process of efficient testing is achieved through an automated mechanism. It eliminates the need for manual force application or frequent fixture changes, automatically completing operations such as fastener fixing, testing position calibration, application and reset of torsional force. This significantly reduces human error, improves the consistency of test results, and significantly shortens the testing time per test, making it more suitable for batch testing of fasteners. During the testing process, the torsional deformation angle can be visualized and read in real time, and the sliding data is collected synchronously. Operators can immediately determine whether the fastener is qualified. Furthermore, multi-dimensional testing data can be completely recorded and archived, meeting the data traceability requirements of engineering quality control. The equipment has a simplified structure, eliminating the need for complex structures such as large double columns. Its manufacturing and operating costs are far lower than those of general-purpose large-scale mechanical performance testing machines. It meets the quality testing needs of small and medium-sized manufacturing enterprises and is also suitable for rapid on-site testing by construction units, balancing practicality and economy. It is also equipped with anti-collision and buffer structures to ensure the integrity of the equipment and fasteners during the testing process. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see the appendix Figure 1 and attached Figure 2 One embodiment of this utility model includes a sliding amount detection mechanism 1 and a torsion mechanism 2. Torsion mechanism 2 is mounted on the surface of sliding amount detection mechanism 1; The torsion mechanism 2 includes a sliding component 21, a rotating component 22, and a driving component 23; The surface of the sliding component 21 is in contact with the surface of the sliding amount detection mechanism 1. A rotating component 22 is mounted on the surface of the sliding component 21, and a driving component 23 is provided on the side of the rotating component 22. Specifically, the sliding amount detection mechanism 1 provides a stable installation for the torsion mechanism 2. Its surface is in direct contact with the sliding component 21 of the torsion mechanism 2. The sliding component 21 can slide along the surface of the sliding amount detection mechanism 1, driving the torsion mechanism 2 to move as a whole. The rotating component 22 of the torsion force is precisely aligned with the fastener to be tested installed on the sliding amount detection mechanism 1, avoiding detection errors caused by positional offset.

[0026] Please see the appendix Figure 3 The sliding amount detection mechanism 1 includes a base component 11, which is installed at the bottom of the torsion mechanism 2, and a compression component 12 is provided on the top of the base component 11; The base component 11 includes a mounting bracket 111, a vertical plate 112, a base plate 113, an adjustment push rod 115, a reinforcing plate 116, and a fixing block 117; Mounting bracket 111 is mounted on top of torsion mechanism 2; A vertical plate 112 and a fixing block 117 are fixedly connected to the outer surface of the mounting frame 111. The vertical plate 112 is located inside the fixing block 117. A frame rod is fixedly connected to the inner side of the vertical plate 112. An anti-collision pad is fixedly connected to the outer surface of the vertical plate 112. A reinforcing plate 116 is fixedly connected to the outer surface of the vertical plate 112. The outer surface of the reinforcing plate 116 is fixed to the top of the mounting frame 111. A base plate 113 is fixedly connected to the bottom of the mounting frame 111. A sliding groove 114 is opened on the surface of the base plate 113. An adjustment push rod 115 is fixedly attached to the inner wall of the mounting frame 111. Specifically, the frame rod fixed inside the upright plate 112 is the direct assembly carrier for the wheel buckle fastener to be tested. The fastener needs to be fitted onto the frame rod to complete the initial installation. The anti-collision pad fixedly connected to the outer surface of the upright plate 112 can avoid collision damage to the components during the testing process. The reinforcing plate 116 on the outer surface is fixed to the top of the mounting frame 111 to strengthen the connection strength between the upright plate 112 and the mounting frame 111, prevent the upright plate 112 from deforming under force, and ensure the stability of the test.

[0027] Please see the appendix Figure 3 The compression component 12 includes a pressing push rod 121, an end ring 122, a pressing block 123, a support rod 124, a buffer ring 125, and a cone block 126; The clamping push rod 121 is located on the top of the mounting bracket 111; The outer surface of the pressing push rod 121 is fixed to the inner wall of the fixing block 117. An end ring 122 is fixedly connected to the end of the pressing push rod 121. A pressure block 123 is movably connected to the outer surface of the end ring 122. A support rod 124 is fixedly connected to the side of the pressure block 123 away from the end ring 122. The outer surface of the support rod 124 slides against the inner wall of the upright plate 112. A cone block 126 is fixedly connected to the end of the support rod 124. A buffer ring 125 is fixedly connected to the outer surface of the cone block 126. The inner walls of the cone block 126 and the buffer ring 125 slide against the outer surface of the frame rod. Specifically, the support rod 124 can only move parallel to the inner wall of the upright plate 112, eliminating radial swaying when force is applied, and ensuring that the force applied to the fastener is always along the axial direction of the frame rod. The cone block 126 fixed at the end of the support rod 124 is the final force-applying component, and the buffer ring 125 fixed on the outer surface has both protective and sealing functions, which not only avoids damage to the cone block 126 and the fastener, but also enhances the fit and sealing between the cone block 126 and the fastener. The inner walls of both the cone block 126 and the buffer ring 125 slide against the outer surface of the frame rod, allowing them to move along the axial direction of the frame rod.

[0028] Please see the appendix Figure 4 and attached Figure 5 The sliding component 21 includes a displacement plate 211; The outer surface of the displacement plate 211 slides against the outer surface of the mounting bracket 111, and the outer surface of the displacement plate 211 slides against the outer surface of the base plate 113; The surface of the displacement plate 211 is provided with a sliding key 212, the outer surface of the sliding key 212 slides against the inner wall of the sliding groove 114, and an expansion block 213 is fixedly connected to the outer surface of the displacement plate 211, the outer surface of the expansion block 213 is fixed to the end of the adjusting push rod 115. The rotating component 22 includes a support frame 221, a rotating shaft 222, a rotating ring 223, a worm gear block 224, a frame 225, a round rod 226, and a positioning block 227; The support frame 221 is disposed on the side of the mounting frame 111; The outer surface of the support frame 221 is fixed to the outer surface of the displacement plate 211. The inner wall of the support frame 221 is rotatably connected to the rotating shaft 222. The outer surface of the rotating shaft 222 is fixedly connected to the worm gear block 224. The outer surface of the worm gear block 224 is fixedly connected to the rotating ring 223. The outer surface of the rotating ring 223 rotates with the inner wall of the support frame 221. The end of the rotating shaft 222 is fixedly connected to the frame 225. The inner wall of the frame 225 is fixedly connected to the round rod 226. The outer surface of the frame 225 rotates with the outer surface of the positioning block 227. The drive component 23 includes a housing 231, a drive motor 232, a transmission shaft 233, and a worm gear 234; A drive motor 232 is fixedly connected to the inner wall of the housing 231, a transmission shaft 233 is fixedly connected to the end of the drive motor 232, and a worm gear 234 is fixedly connected to the outer surface of the transmission shaft 233. The outer surface of the housing 231 is fixed to the outer surface of the displacement plate 211, the outer surface of the worm 234 meshes with the outer surface of the worm wheel block 224, and the outer surface of the transmission shaft 233 rotates with the inner wall of the displacement plate 211.

[0029] Specifically, the expansion block 213 fixed on the outer surface of the displacement plate 211 is directly fixed to the end of the adjustment push rod 115 of the base component 11. When the adjustment push rod 115 extends or retracts, it will drive the displacement plate 211 to slide along the mounting frame 111 and the base plate 113 through the expansion block 213, thereby synchronously driving the rotating component 22 and the driving component 23 fixed on the displacement plate 211 to move until the round rod 226 of the rotating component 22 is precisely aligned with the fastener, and the worm 234 is precisely engaged with the worm wheel block 224 of the rotating component 22. Through the reduction transmission characteristics of the worm wheel 234, the high-speed rotation of the drive motor 232 is converted into the low-speed, high-torque rotation of the worm wheel block 224.

[0030] Working principle: The worker installs the ringlock steel pipe scaffold coupler to be tested onto the frame rod of the base component 11 in the slip detection mechanism 1 and the inner wall round rod 226 of the frame 225 of the rotating component 22 in the torsion mechanism 2, simulating the state of the coupler connecting the upright and horizontal bar in the actual scaffolding installation scenario. Then, the compression component 12 is activated, and the pressing push rod 121 on the fixing block 117 extends first, pushing the end ring 122 and the pressure block 123 to move, driving the support rod 124 along... The upright plate 112 slides, causing the cone block 126 at the end of the support rod 124 to fit tightly against the buffer ring 125, thus completing the fastening. Next, the push rod 121 is pressed to continue applying force, transmitting the thrust along the support rod direction to the cone block 126 through the pressure block 123 and the support rod 124, providing a load for the sliding amount detection. Then, the adjusting push rod 115 of the base component 11 is activated. The adjusting push rod 115, through the expansion block 213, drives the displacement plate 211 of the sliding component 21. Using the sliding key 212 to slide along the groove 114 of the base plate 113, the relative position of the fastener and each detection component is further calibrated. At the same time, it is ensured that the arrow on the surface of the round rod 226 is aligned with the zero mark line of the positioning block 227. The drive motor 232 of the drive component 23 is started, and the drive motor 232 drives the transmission shaft 233 to rotate. The worm 234 on the transmission shaft 233 meshes with the worm wheel block 224, driving the rotating shaft 222, the frame 225 and the round rod 226 to rotate, applying a torsional force to the fastener. The torsional deformation angle is read by the scale of the positioning block 227 and the arrow of the round rod 226. At the same time, under the action of the compression component 12 along the frame rod, the sliding amount detection mechanism 1 collects the relative displacement data of the cone block 126, the buffer ring 125 and the frame rod to determine the sliding amount. After the detection is completed, the drive motor 232 rotates in reverse to reset the torsion component. The adjustment push rod 115 retracts, driving the displacement plate 211 and the torsion mechanism 2 to return to their positions. The pressing push rod 121 retracts to release the fixation.
