[0024] In order to facilitate the fatigue strength test of the steel wire rope under different tightness conditions, one end of the screw rod 11 is fixedly connected to the crank handle 4, the screw 11 is rotatably connected to the box body 1, one end of the slider 12 is fixedly connected to the fixed cylinder 14, the internal thread of the fixed cylinder 14 is connected to the screw, the surface of the slider 12 is slidably connected to the limiting slide groove 13, and the limiting slide groove 13 is fixedly connected to the box body 1.

[0025] In order to facilitate the simulation of the scene in which the wire rope is continuously impacted by gravel in the elevator shaft and effectively improve the range of fatigue strength testing of the wire rope, a friction plate 17 is fixedly connected to the bottom of the slider 12, and a friction wheel 18 is frictionally connected to the bottom of the friction plate 17. The friction wheel 18 is rotatably connected to the box body 1, and a rotating plate 19 is rotatably connected to the surface of the friction wheel 18 through a pin shaft. The surface of the rotating plate 19 is rotatably connected to a connecting rod 20 through a pin shaft, and an impact plate 21 is rotatably connected to the bottom of the connecting rod 20 through a pin shaft.

[0026] In order to facilitate the fixation of the two ends of the wire rope and thus conduct fatigue strength testing on it, a fixing plate 24 is threadedly connected to the surface of the screw rod 11, an inclined groove is provided inside the fixing plate 24, a sliding column 23 is slidably connected inside the inclined groove, one end of the sliding column 23 is fixedly connected to a fixing frame 22, and another set of fixing cylinders 14 is arranged below the fixing frame 22.

[0027] Furthermore, the impact plate 21 is slidably connected to the box body 1 , two sets of outer shells 16 are fixedly connected inside the box body 1 , and multiple sets of pulleys 15 are rotatably connected inside the box body 1 .

[0028] In order to facilitate the simulation of the scene when the wire rope is used in rainwater and improve the detection range, the fixed plate 24 is slidably connected to the box body 1, the fixed cylinder 14 and the fixed frame 22 are made of high-strength steel materials, and the interior of the outer shell 16 is fixedly connected to the water tank 5 through a water inlet pipe, and the water tank 5 and the box body 1 are detachably connected.

[0029] In order to facilitate the collection of wastewater and the observation of the wastewater by operators, an observation port is provided on the surface of the baffle 2 , and the water outlets of the two sets of shells 16 are located directly above the collection bin 3 .

[0030] Working principle and use process of the utility model: After the utility model is installed, the baffle 2 is first removed from the front of the box body 1, and then water is added to the inside of the water tank 5, and then one end of the wire rope is fixed to the inside of the fixed cylinder 14 by screws, and then the other end is passed through the shell 16 set on the side of the pulley 15, so that it shuttles between multiple groups of pulleys 15, and then the other end is fixed to the bottom of the fixed frame 22 by screws, and then the motor 6 is started to rotate and drive the turntable 7 to rotate through the rotating shaft, and the rotation of the turntable 7 drives the first swing rod 8 to swing through the pin shaft, and the first swing rod 8 drives the adjusting rod 9 to swing through the pin shaft, and the other end of the adjusting rod 9 drives the second swing rod 9 to swing through the pin shaft. The swing rod 10 swings, and the second swing rod 10 pulls the slider 12 to slide inside the limiting slide groove 13 through the pin shaft during the swinging process, and can repeatedly pull the fixed cylinder 14 to move left and right. The fixed cylinder 14 will pull the steel wire rope inside the shell 16 to slide on the pulley surface during the movement, and the steel wire rope in a loose state can be tested. At the same time, when the motor 6 is started, the water inside the water tank 5 will be continuously added to the inside of the two groups of shells 16, which can effectively simulate the working state of the steel wire rope in rainy weather, so as to detect its fatigue resistance, and the detection efficiency is high. The water after the detection will flow along the inside of the shell 16 to the inside of the collection bin 3 for collection;

[0031] When the wire rope needs to be tested in a relatively tight state, the crank handle 4 is turned to drive the screw rod 11 to rotate. When the screw rod 11 rotates, it drives the adjusting rod 9 to change its inclination angle through the pin shaft, thereby affecting the swing amplitude of the second swing rod 10, and controlling the distance that the slider 12 moves left and right in the limiting slide groove 13. At the same time, the screw rod 11 drives the fixing plate 24 to move left and right during the rotation process. The movement of the fixing plate 24 can drive the sliding column 23 to move upward through the inclined groove. The upward movement of the sliding column 23 drives the fixing frame 22 to move upward. The movement of the fixing frame 22 can drive one end of the lower wire rope to move upward, so that the wire rope can be made tighter inside the housing 16, and the fatigue strength of the wire rope in a relatively tight state can be detected, and the detection range is wide.

[0032] At the same time, when the slider 12 slides left and right inside the limiting slide groove 13, the movement of the slider 12 will drive the friction plate 17 below to move, and the friction transmission of the friction plate 17 will drive the friction wheel 18 to rotate forward and reverse. The rotation of the friction wheel 18 drives the rotating plate 19 to rotate through the pin shaft, and the rotation of the rotating plate 19 drives the connecting rod 20 to swing through the pin shaft. During the swinging process, the connecting rod 20 will drive the impact plate 21 below to move up and down through the pin shaft, which can simulate the work of the wire rope being constantly hit by gravel on its surface during use on the construction site, and can better detect the fatigue strength of the wire rope.
