Description

Technical Field

[0001] This utility model relates to the field of wire rope testing technology, specifically a wire rope performance testing safety clamping mechanism. Background Technology

[0002] A wire rope is a helical bundle of steel wires that meet the requirements for mechanical properties and geometric dimensions, twisted together according to certain rules. A wire rope consists of steel wires, a core, and lubricant. During the use of wire ropes, monitoring the strength of the wire rope is crucial to prevent the wire rope from exceeding its load-bearing limit and causing a major safety accident. In existing technologies, a pressure-side tension sensor is typically used to measure the tension of a wire rope in order to measure its load. However, during the deformation process of the wire rope, a U-shaped screw and nut are used to compress the wire rope to induce deformation, which is a complex operation. When repeatedly measuring the tension at different locations on the wire rope, the nut needs to be repeatedly removed, resulting in a significant workload. To address the problems in existing technologies, utility model CN221038440U discloses a wire rope safety detection device (hereinafter referred to as Prior Art 1), which includes a pressure-side tension sensor. The pressure-side tension sensor comprises a housing, a placement block, a reinforcing rope groove, and a wire rope tensioning device. The tensioning device includes: a pressure block, disposed at the top of the housing and between two placement blocks, with a pressure groove at the bottom of the pressure block, which, along with two wire rope grooves, can simultaneously engage the wire rope; two threaded rods, including a driving rod and a driven rod, disposed inside the housing, with their top ends threaded through the housing and connected to the pressure block, and their bottom ends rotatably connected to the housing; a driving wheel and a driven wheel, respectively connected to the driving rod and the driven rod; a belt, connected to both the driving wheel and the driven wheel; a drive device, disposed on the housing, for driving the threaded rods to rotate; and a locking device, disposed on the drive device, for locking the drive device; wherein, the pressure block can move upward or downward by rotating the two threaded rods, thereby enabling the measurement of the wire rope tension.

[0003] Existing technology 1 only requires operating the drive device to fix the wire rope without repeatedly disassembling the nut; however, the effect of fixing the wire rope by the pressure block alone in existing technology 1 is not good, and it is easy for the wire rope to loosen from the limiting area during the tensile stress process, which affects the accuracy of the test data. Utility Model Content

[0004] The purpose of this utility model is to provide a safe clamping mechanism for testing the performance of steel wire ropes. In actual use, it can solve the problem that the existing technology of fixing steel wire ropes by pressure blocks is not effective and easily causes the steel wire ropes to loosen from the limiting area during the tensile stress process, thus affecting the accuracy of the test data.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A wire rope performance testing safety clamping mechanism includes a frame and clamping devices installed on the upper and lower sides of the frame. The clamping devices include two connecting components and a gripper mechanism. A limiting area for limiting the wire rope body is formed between the two connecting components. The gripper mechanism includes a mounting part, a drive unit, a gripper body, and a limiting groove provided on the mounting part. The gripper body is symmetrically and slidably mounted on the mounting part. The drive unit is used to drive the gripper body to clamp the steel rope. A drive device is connected to the mounting part. The connecting component is provided with a locking mechanism and a locking groove. The locking mechanism is used to cooperate with the locking groove provided on another connecting component, and the limiting groove is used to drive the locking mechanism to move.

[0006] Preferably, the connecting assembly includes a connector, a locking member, and a threaded post fixedly connected to the connector. The connector has a fixing hole, the threaded post is used to mate with a fixing hole on another connector, the locking member is threadedly connected to the threaded post, the locking groove is provided on the threaded post, and the locking mechanism is installed on the connector.

[0007] Preferably, the connector has anti-slip texture on the side that contacts the wire rope body.

[0008] Preferably, the locking mechanism includes a locking pin and a spring, the connecting member is provided with a sliding groove, the locking pin is provided with a stepped platform, and the stepped platform is connected to the sliding groove through the spring.

[0009] Preferably, a buffer block is installed on the locking pin.

[0010] Preferably, there are several locking slots, which are arranged sequentially from top to bottom along the threaded post.

[0011] Preferably, the fixing hole is provided with a guide slope.

[0012] Compared with the prior art, the present invention has the following beneficial effects: In this utility model, after the two connecting components in the clamping device are connected, one end of the wire rope body located in the limiting groove can be fixed in the limiting area; the limiting groove is provided with a clearance groove, and the other end of the wire rope body passes through the clearance groove and enters the limiting groove of another gripper mechanism, and is fixed again by the two connecting components. After the connecting component contacts the limiting grooves on the two mounting parts, the driving device connected to the mounting part drives the two gripper mechanisms to move away from each other. During the movement of the gripper mechanisms, the connecting component is always pressed against the limiting groove. The limiting groove can press the locking mechanism into the locking groove, thereby further fixing the two connected components together and preventing the two connecting components from loosening during the wire rope body tensile test, which would affect the fixing effect of the wire rope body.

[0024] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0025] See Figures 1-3 This embodiment discloses a steel wire rope performance testing safety clamping mechanism, including a frame and clamping devices 102 installed on the upper and lower sides of the frame. The clamping device 102 includes two connecting components 103 and a gripper mechanism 104. A limiting area for limiting the steel wire rope body 101 is formed between the two connecting components 103. The gripper mechanism 104 includes a mounting part 105, a drive unit, a gripper body 107, and a limiting groove 106 provided on the mounting part 105. The gripper body 107 is symmetrically slidably mounted on the mounting part 105. The drive unit is used to drive the gripper body to clamp the steel rope. A drive device 108 is connected to the mounting part 105. The connecting component 103 is provided with a locking mechanism 109 and a locking groove 110. The locking mechanism 109 is used to cooperate with the locking groove 110 provided on another connecting component 103. The limiting groove 106 is used to drive the locking mechanism 109 to move.

[0026] In this embodiment, the clamping devices 102 connected to the upper and lower sides of the frame can fix the upper and lower ends of the wire rope body 101. After the two connecting components 103 in the clamping device 102 are connected, one end of the wire rope body 101 located in the limiting groove 106 can be fixed in the limiting area. The limiting groove 106 is provided with a clearance groove. The other end of the wire rope body 101 passes through the clearance groove and enters the limiting groove 106 of another gripper mechanism 104, and is fixed again by the two connecting components 103. After the connecting component 103 contacts the limiting groove 106 on the two mounting parts 105, the driving device 108 connected to the mounting part 105 is used to drive the two gripper mechanisms 104 to move away from each other. During the movement of the gripper mechanism 104, the connecting component 103 is always pressed against the limiting groove 106, and the limiting groove 106 can press the locking mechanism 109 into the limiting groove 106. The locking groove 110 further secures the two connecting components 103 connected together, preventing them from loosening during the tensile testing of the wire rope body 101 and affecting the fixing effect of the wire rope body 101. In this embodiment, the driving device 108 is a conventional hydraulic telescopic device in the prior art. The fixed end of the driving device 108 is fixedly connected to the bracket, and the telescopic end of the driving device 108 is fixedly connected to the mounting part 105. The driving unit is a conventional hydraulic driving unit in the prior art. After the driving unit drives the gripper body 107 to move towards each other, it can clamp the wire rope passing through the relief groove, so that even if the wire rope body 101 breaks during the testing process, the gripper body 107 can still clamp and fix the wire rope body 101, preventing the broken wire rope and connecting components 103 from falling out of the limiting groove 106. The specific structure and function of the driving unit and driving device 108 will not be described in detail here.

[0027] In some embodiments, the connecting assembly 103 includes a connector 113, a locking member 114, and a threaded post 115 fixedly connected to the connector 113. The connector 113 is provided with a fixing hole 116. The threaded post 115 is used to cooperate with the fixing hole 116 on another connector 113. The locking member 114 is threadedly connected to the threaded post 115. The locking groove 110 is provided on the threaded post 115. The locking mechanism is installed on the connector 113. In this embodiment, the threaded post 115 fixedly connected to the connector 113 is slidably connected to the fixing hole 116 provided on the other connector 113, so that the size of the limiting area formed after the two connectors 113 are connected can be adaptively adjusted according to the different dimensions of the wire rope body 101. After the locking member 114 is installed at the end of the threaded post 115 located outside the connector 113, the two connectors 113 can be connected as a whole. During the process of the driving device 108 driving the two gripper mechanisms 104 to move away from each other, the connector 113 is always pressed against the limiting groove 106, so that the locking mechanism installed on the connector 113 can be pressed into the locking groove 110 provided on the other connector 113, thereby limiting and fixing the two connectors 113 for the second time. The cooperation between the locking mechanism 109 and the locking member 114 can double lock the two connectors 113, thereby improving the stability and fixing effect of the connecting assembly 103 during the tensile testing process of the wire rope body 101.

[0028] In some embodiments, the connector 113 has anti-slip textures on the side that contacts the wire rope body 101. In this embodiment, the anti-slip textures increase the friction between the wire rope body 101 and the connector 113, further improving the fixing effect of the connector 113 on the wire rope body 101.

[0029] In some embodiments, the locking mechanism 109 includes a locking pin 117 and a spring 118. A sliding groove is provided on the connecting member 113, and a stepped platform 112 is provided on the locking pin 117. The stepped platform 112 is connected to the sliding groove via the spring 118. In this embodiment, during the movement of the gripper mechanism 104, the connecting member 113 is always pressed against the limiting groove 106. The limiting groove 106 can press the locking pin 117 into the locking groove 110, thereby providing secondary limiting and fixing for the two connecting members 113. The spring 118 acts as a buffer when the locking pin 117 moves into the locking groove 110. After the detection of the wire rope body 101 is completed, the locking pin 117 resets under the force of the spring 118.

[0030] In some embodiments, a limiting block is provided in the slide. After the stepped platform 112 contacts the limiting block, it can limit the locking pin 117, preventing the spring 118 from failing or being damaged when it is in a compressed state for a long time, and preventing the spring 118 from being over-compressed.

[0031] In some embodiments, a buffer block 111 is installed on the locking pin 117. In this embodiment, the buffer block 111 is made of rubber material. By setting the buffer block 111, the impact force generated when the locking pin 117 collides with the limiting groove 106 when the locking pin 117 is pressed against the limiting groove 106 can be absorbed, thereby avoiding wear of the locking pin 117.

[0032] In some embodiments, there are multiple locking slots 110, which are arranged sequentially from top to bottom along the threaded post 115. By providing multiple locking slots 110, the threaded post 115 can cooperate with locking slots 110 at different positions when the size of the limiting area changes due to the size of different wire rope bodies 101. In this embodiment, there are two locking slots 110, which are arranged sequentially from top to bottom along the threaded post 115.

[0033] In some embodiments, a guide ramp is provided on the fixing hole 116. In this embodiment, the guide ramp can guide the threaded post 115, so that the threaded post 115 can quickly and accurately enter the fixing hole 116.

[0034] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
