Description

Technical Field

[0002] Steel wire ropes are used for lifting and traction. During use, friction and wear, fatigue damage, partial wire breakage and deformation will occur, which will reduce the tensile strength of the steel wire ropes and invisibly reduce the safety performance. In order to ensure the reliability and safety of repeated use of steel wire ropes, they must be tested for tension. Usually, a tensile testing machine is used to test the steel wire ropes. The tensile machine is used to stretch the steel wire ropes to determine whether the tensile strength of the steel wire ropes is qualified.

[0049] Two support rings 10 are respectively arranged on one side of the wire pushing ring 9 , and each of the support rings 10 is mounted on the installation box 5 .

[0050] For example, by passing the wire rope through the support ring 10 and the push wire ring 9, the two ends of the wire rope are clamped with two wire rope clamping assemblies 3 respectively, and a wire rope clamping assembly 3 is driven to move by the lifting assembly to straighten the wire rope, and then the first connecting plate 7 is driven to move by the first screw slide 6, and the pressure device 8 is driven to move by the first connecting plate 7, and the push wire ring 9 is pushed by the pressure device 8 to resist the movement, and the wire rope is pushed by the push wire ring 9 to deform with the two support rings 10 as the fulcrum, and tension is applied at the same time, and the stroke of the first screw slide 6 is determined according to the value of the pressure device 8, and then the lifting assembly continues to drive a wire rope clamping assembly 3 to move, thereby completing the tensile test of the wire rope under tension state, solving the problem that the existing wire rope tensile test cannot detect the tensile strength of the wire rope under different tension states.

[0051] As an optional embodiment, the wire rope clamping assembly 3 includes:

[0052] A mounting frame 11, wherein a support plate 12 is fixedly disposed in the middle thereof;

[0053] A second connecting plate 13, vertically arranged on one side of the supporting plate 12;

[0054] A wire passing tube 14 is arranged on one side of the second connecting plate 13, and the middle part of the wire passing tube 14 is rotatably connected to the second connecting plate 13;

[0055] The locking assembly is arranged beside the second connecting plate 13 and is rotated to the locking assembly through one end of the wire tube 14, and the locking assembly works to complete the clamping of the wire rope.

[0056] As an optional embodiment, the locking assembly includes:

[0057] A fixing plate 15, fixedly arranged beside the second connecting plate 13;

[0058] A threaded rod 16 is passed through the fixing plate 15 and is threadedly connected to the fixing plate 15. One end of the threaded rod 16 is rotatably connected to a first clamping plate 17, and the other end is fixed with a handle 18. The first clamping plate 17 is slidably connected to the second connecting plate 13.

[0059] At least one second clamping plate 19 is provided, one end of which is fixedly arranged beside the pipe opening of the wire passing pipe 14 .

[0061] As an optional embodiment, a disc 20 is provided on the side of the second connecting plate 13 away from the wire passing tube 14, and the center of the disc 20 is fixedly connected to the shaft rod of the wire passing tube 14.

A spring 25 is sleeved on the pull rod 23, and the two ends of the spring 25 respectively abut against the fixing block 22 and the limiting block 24.

[0062] For example, when the wire tube 14 rotates counterclockwise, the wire tube 14 drives the disc 20 to rotate through the shaft, so that the disc 20 drives the limit slot 21 to rotate to the limit block 24, and the limit block 24 is pushed into the limit slot 21 by the spring 25, thereby locking the disc 20, so that when the first clamping plate 17 moves toward the second clamping plate 19, there is no need to hold the wire tube 14 by hand, thereby improving the efficiency of locking the wire rope. When the wire rope test is completed, the limit block 24 squeezes the spring 25 to exit the limit slot 21 by pulling the pull rod 23. At this time, the disc 20 can rotate freely, and the wire tube 14 can be reset by rotating the wire tube 14 clockwise.

[0063] As an optional embodiment, a third connecting plate 26 is fixedly provided on a side of the second connecting plate 13 close to the support plate 12, and the third connecting plate 26 is rotatably connected to the support plate 12.

[0066] A push plate 28 is arranged on a side of the mounting plate 2 away from the wire rope clamping assembly 3, and the push plate 28 is transmission-connected to one of the wire rope clamping assemblies 3;

[0067] The hydraulic cylinder 29 is fixedly mounted on the mounting plate 2 , and the telescopic rod of the hydraulic cylinder 29 is fixedly connected to the center of the pushing plate 28 .

[0070] For example, the slider 31 is moved by pushing the plate 28, and the slider 31 is used to move the tensioner 30 and the pointer 33. The numerical value displayed on the tensioner 30 is used to obtain the current tension of the wire rope, and the pointer 33 moves on the scale 32 to obtain the stretching distance of the wire rope, which is used to calculate the stretching rate and to detect whether there is a problem with the tensioner 30. When measuring the second wire rope, if the stretching distance of the second wire rope is longer than the stretching distance of the first wire rope, but the reading of the tensioner 30 of the second wire rope is lower than the reading of the tensioner 30 of the first wire rope, it means that there is a problem with the tensioner 30 and a new tensioner 30 needs to be replaced.

[0071] As an optional embodiment, an electric push rod 34 is slidably connected to the first connecting plate 7, and the telescopic rod of the electric push rod 34 is fixedly connected to the outer wall of the wire pushing ring 9.

[0081] For example, after both ends of the wire rope are clamped, the second screw slide 36 drives the installation box 5 to move, and the installation box 5 drives the first screw slide 6 and the support seat 37 to move, so that the wire push ring 9 and the two support rings 10 are sleeved on the wire rope through the wire inlet 38, and there is no need to first insert the wire rope into the push ring 9 and the two support rings 10 and then perform the clamping work, which improves the efficiency of the wire rope tensile test. After the support ring 10 is sleeved on the wire rope, the second motor 39 drives the connecting rod 40 to rotate, and the connecting rod 40 drives the belt synchronous wheel group 41 to work, so that the belt synchronous The wheel group 41 drives the gear 42 to rotate, and drives the outer gear ring 43 to rotate through the gear 42, and drives the support ring 10 to rotate through the outer gear ring 43 to close the wire inlet 38 on the support seat 37, and drives the presser 8 to move through the first screw slide 6, and pushes the pressure plate 35 through the detection rod of the presser 8, and drives the push wire ring 9 to contact the wire rope through the pressure plate 35 to deform with the two support rings 10 as the fulcrum, and apply tension at the same time, thereby completing the tensile test of the wire rope under tension state, which solves the problem that the existing wire rope tensile test cannot detect the tensile strength of the wire rope under different tension states.
