Description

Technical Field

[0001] This utility model relates to the technical field of wire rope testing, and in particular to a wire rope testing tensile clamp. 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 rope core, and lubricating grease.

[0003] Existing wire rope testing methods, such as the horizontal tensile testing machine wire rope tensile clamp disclosed in utility model patent application number 202120807352.3, mainly include a base plate, a fixed block fixedly installed on the top of the base plate, and a sliding block slidably installed on the top of the base plate. In use, the threaded sleeve drives the threaded rod to move, the threaded rod drives the clamping plate to move, and at the same time fixes both ends of the wire rope. At this time, the hydraulic cylinder is activated, and the hydraulic cylinder drives the sliding block to move, so that the wire rope can be subjected to a tensile test.

[0004] However, most existing clamps require manual operation for clamping, resulting in poor clamping effect. The wire rope is easy to fall off during the testing process, and most can only perform unilateral tensile testing, making the tensile method relatively simple and the test data prone to deviation. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a wire rope testing tension clamp that not only facilitates the fixing of both ends of the wire rope, improves the fixing efficiency, and ensures the fixing and clamping effect of the wire rope, but also allows for testing of the wire rope through various methods such as horizontal tension, coiling tension, and simultaneous tension at both ends, ensuring the test results.

[0006] This utility model discloses a wire rope tensile testing fixture, including a support mechanism; it also includes a moving mechanism, a first fixing mechanism, a winding mechanism, a second fixing mechanism, and a limiting mechanism. The moving mechanism is mounted on the support mechanism and drives the first fixing mechanism to move. The first fixing mechanism is mounted on the moving mechanism and fixes one end of the wire rope. The winding mechanism is mounted on the support mechanism and drives the second fixing mechanism to rotate. The second fixing mechanism is mounted on the winding mechanism and fixes the other end of the wire rope. The limiting mechanism is mounted on the support mechanism and fixes either the moving mechanism or the winding mechanism. The operator fixes both ends of the wire rope to the first fixing mechanism and the second fixing mechanism respectively. When the wire rope needs to be wound and stretched, the limiting mechanism fixes the moving mechanism, and the winding mechanism drives the second fixing mechanism to rotate to perform a winding and tensile test on the wire rope. When the wire rope needs to be stretched horizontally, the limiting mechanism fixes the winding mechanism, and the moving mechanism is activated to drive the first fixing mechanism to move to perform a horizontal tensile test on the wire rope. When the limiting mechanism is removed, the moving mechanism and the winding mechanism can be activated simultaneously to perform synchronous tensile tests on both ends of the wire rope.

[0007] Preferably, the support mechanism includes a base, a protective plate, a first frame, a controller, and a second frame. The bottom end of the base is connected to the ground, the bottom end of the protective plate is connected to the top end of the base, the bottom end of the first frame is connected to the top end of the base, and the first frame has positioning holes. The controller is installed on the first frame, and the bottom end of the second frame is connected to the top end of the base. The second frame also has positioning holes. By setting up the protective plate, the sudden breakage of the wire rope can be prevented from injuring people. The operator controls the tension and distance through the controller.

[0008] Preferably, the moving mechanism includes two sets of guide rails, a main hydraulic cylinder, and a slider. Both sets of guide rails are installed between the first frame and the second frame. The main hydraulic cylinder is installed on the first frame, and the slider is slidably installed on the two sets of guide rails and connected to the top of the main hydraulic cylinder. The slider has positioning holes. When the wire rope needs to be wound and stretched, the limiting mechanism is inserted into the positioning holes of the first frame and the slider for fixation. When the wire rope needs to be stretched horizontally, the operator controls the main hydraulic cylinder to retract through the controller. The main hydraulic cylinder drives the slider to slide along the two sets of guide rails, which facilitates the horizontal stretching of the wire rope.

[0009] Preferably, the first fixing mechanism includes a positioning frame, two sets of first hydraulic cylinders, a first column, a first clamping plate, and a first rubber strip. The bottom end of the positioning frame is connected to the top end of the slider. The positioning frame has a U-shaped groove and a guide groove. Both sets of first hydraulic cylinders are mounted on the positioning frame. The first column is mounted on the positioning frame. The first clamping plate is slidably mounted in the first column and the guide groove, and the top end of the first clamping plate is connected to the bottom end of the two sets of first hydraulic cylinders. The first clamping plate has a U-shaped groove, and the first rubber strip is installed in the U-shaped groove of the first clamping plate. The operator places one end of the wire rope in the U-shaped groove of the positioning frame, activates the two sets of first hydraulic cylinders to push the first clamping plate down, so that the first rubber strip abuts against the wire rope, enhancing the fixing effect of the wire rope. Then, the wire rope is knotted to prevent the wire rope from being pulled out of the U-shaped groove.

[0010] Preferably, the winding mechanism includes a stepper motor, a reducer, and a drive shaft. The stepper motor is mounted on the second frame, the reducer is mounted on the second frame and its power input end is connected to the power output end of the stepper motor, and the drive shaft is rotatably mounted on the second frame and connected to the reducer for transmission. The drive shaft has two sets of positioning holes. When the wire rope needs to be wound and stretched, the operator starts the stepper motor through the controller. The stepper motor drives the drive shaft to rotate through the reducer, and the drive shaft drives the second fixing mechanism to rotate to wind and stretch the wire rope. When the wire rope needs to be stretched horizontally, the limiting mechanism is inserted into the positioning holes of the second frame and the drive shaft for fixation.

[0011] Preferably, the second fixing mechanism includes a positioning box, two sets of second hydraulic cylinders, a second column, a second clamping plate, and a second rubber strip. The positioning box is mounted on the drive shaft and has a U-shaped groove and a guide groove. Both sets of second hydraulic cylinders are mounted on the positioning box. The second column is mounted on the positioning box. The second clamping plate is slidably mounted in the second column and the guide groove, and the top of the second clamping plate is connected to the bottom of the two sets of second hydraulic cylinders. The second clamping plate has a U-shaped groove, and the second rubber strip is installed in the U-shaped groove of the second clamping plate. The operator places the other end of the wire rope in the U-shaped groove of the positioning box, activates the two sets of second hydraulic cylinders to push the second clamping plate down, so that the second rubber strip abuts against the wire rope, enhancing the fixing effect of the wire rope. Then, the wire rope is knotted to prevent the wire rope from being pulled out of the U-shaped groove.

[0012] Preferably, the limiting mechanism includes two sets of fixed posts, a connecting plate, and a handle. Both sets of fixed posts are inserted into positioning holes. The bottom end of the connecting plate is connected to the top end of the two sets of fixed posts, and the handle is installed on the connecting plate. The operator operates the handle to drive the connecting plate, which in turn drives the two sets of fixed posts to descend, facilitating the insertion of the fixed posts into the positioning holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the workers fix the two ends of the wire rope to the first fixing mechanism and the second fixing mechanism respectively. When it is necessary to wind and stretch the wire rope, the limiting mechanism is used to fix the moving mechanism, and the winding mechanism drives the second fixing mechanism to rotate to perform a winding and stretching test on the wire rope. When it is necessary to stretch the wire rope horizontally, the limiting mechanism is used to fix the winding mechanism, and the moving mechanism is started to drive the first fixing mechanism to move to perform a horizontal stretching test on the wire rope. When the limiting mechanism is pulled out, the moving mechanism and the winding mechanism can be started simultaneously to perform a synchronous stretching test on both ends of the wire rope.
