Steel wire rope is composed of steel wire, rope core and grease. Steel wire rope is first twisted into strands by multiple layers of steel wires, and then a certain number of strands are twisted into a spiral rope with the rope core as the center. It needs to withstand the action of alternating loads during use. The performance is mainly determined by the mechanical properties of the steel wire, the surface state of the steel wire and the structure of the wire rope. Steel wire materials include carbon steel or alloy steel, which are formed by cold drawing or cold rolling. The cross section of the steel wire is round or shaped. The shaped cross-section steel wire is mainly used for the production of sealed steel wire ropes.

[0021] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0022] Please refer to Figure 1 , Figure 2 and Figure 3As shown, the present invention provides a wire rope clamping and adjusting device 100, comprising a base plate 1, two U-shaped frames 2 are symmetrically arranged near the center of the top of the base plate 1, the top of each U-shaped frame 2 is fixedly connected to a vertical plate 23, the inner side of the vertical plate 23 is fixedly connected to a horizontal slide rail 26, two horizontal sliders 27 are symmetrically slidably arranged at the center of the horizontal slide rail 26, each horizontal slider 27 is fixedly connected to a mounting vertical plate 37, and two limit blocks 38 are symmetrically arranged on the top of the two mounting vertical plates 37 near the center of the vertical plate 23, which are used to cooperate with each other as a set of limit blocks to clamp one end of the wire rope, and the side end of the vertical plate 23 and located on the horizontal slide rail A longitudinal slide rail 24 is fixedly connected at the center above 26, and the longitudinal slide rail 24 and the transverse slide rail 26 are distributed in a T shape. A longitudinal slider 25 that can slide longitudinally is provided on the longitudinal slide rail 24. A threaded cylinder 31 is fixedly connected at the side end of the longitudinal slider 25 and near the bottom center. The bottom end of the threaded cylinder 31 is threadedly connected to the screw rod 3. A motor 22 is fixedly connected near the center of the bottom end of each U-shaped frame 2. The output end of the motor 22 passes through the U-shaped frame 2 and is fixedly connected to the screw rod 3 to drive the longitudinal slider 25 to move longitudinally. A connecting rod 28 is rotatably hinged between the longitudinal slider 25 and the two transverse sliders 27, and the two connecting rods 28 are symmetrically distributed. The connecting rod 28 is rotatably hinged between the longitudinal slider 25 and the two transverse sliders 27 to facilitate the horizontal movement of the two mounting vertical plates 37 through the connecting rod 28 to achieve wire rope clamping.

[0023] Optionally, a plurality of limiting holes 32 are provided from top to bottom near the longitudinal slide rail 24 on the vertical plate 23, and a side block 33 is fixedly connected to one side of the longitudinal slider 25 near the limiting hole 32, and an insertion shaft 34 that can pass through the limiting hole 32 is inserted and slidably inserted inside the side block 33. In this way, the positions of the longitudinal slider 25 and the transverse slider 27 can be locked by the insertion shaft 34 and the limiting hole 32, so as to keep the clamped wire rope. The spacing between adjacent limiting holes can be set smaller, generally smaller than the diameter of the thinnest wire rope to be tested, so that the locking is more stable.

[0024] Preferably, a pull plate 36 is fixedly connected to one end of the insertion shaft 34 away from the limiting hole 32, and a spring 35 is sleeved on the insertion shaft 34. The two ends of the spring 35 are respectively fixedly connected to the side block 33 and the pull plate 36. When the spring 35 is in a free state, the insertion shaft 34 is inserted into one of the limiting holes 32. In this way, the spring 35 is used to achieve the reset locking effect of the insertion shaft 34. When the longitudinal slider 25 needs to move, the pull plate 36 is pulled to withdraw the insertion shaft 34 from the limiting hole 32, thereby releasing the limitation on the longitudinal slider 25. After the longitudinal slider 25 moves to the next suitable limiting hole 32, the pulling force on the pull plate 36 can be released. Then, under the action of the spring 35 restoring the free state, the insertion shaft 34 can be stuck in the limiting hole 32 under the action of the pull plate 36, thereby limiting the longitudinal slider 25 and preventing the two limiting blocks 38 from sliding in opposite directions due to the movement of the longitudinal slider 25 when clamping the wire rope, thereby improving the stability of the equipment clamping effect.

[0025] Optionally, the two U-shaped frames 2 are detachably fixed to the top of the base plate 1. This facilitates the disassembly, assembly and fixing of the U-shaped frames.

[0026] Optionally, the shape of the two limiting blocks 38 on the opposite side is a meshable rack type. In this way, it is convenient to limit the wire rope.

[0027] Optionally, the two limit blocks 38 are detachably fixed to the corresponding mounting upright plates 37. This facilitates the disassembly and maintenance of the limit blocks.

[0028] Optionally, fixed square plates 11 with holes are symmetrically arranged at the four corners of the substrate 1. This makes it easier to fix the substrate 1.

[0029] Optionally, the four corners of the top of the base plate 1 are symmetrically provided with hanging columns 12 with hooks on the top, and the hooks of the hanging columns 12 are higher than the mounting plate 37. This makes it easy to hoist the wire rope clamping and adjusting device.

[0030] Optionally, each transverse slider 27 is fixedly connected to the longitudinal middle position of the corresponding mounting plate 37. In this way, the whole is more stable during clamping.

[0031] The working principle of the wire rope clamping and adjusting device 100 of the present invention is as follows: when in use, first straighten the wire rope and place it between the two groups of limit blocks 38, and then run the two motors 22 at the same time, thereby causing the fixedly connected screw rod 3 to rotate, thereby causing the threaded cylinder 31 connected to the threaded rotation to rise, and then under the cooperation of the two connecting rods 28, the two transverse sliders 27 can move toward each other under the action of the transverse slide rails 26, thereby driving the two groups of limit blocks 38 to move toward each other synchronously, thereby achieving the effect of stably clamping the wire rope.

[0032] The present invention has been described by the above-mentioned relevant embodiments, however, the above-mentioned embodiments are only examples for implementing the present invention. It must be pointed out that the disclosed embodiments do not limit the scope of the present invention. On the contrary, changes and modifications made without departing from the spirit and scope of the present invention are all within the scope of patent protection of the present invention.
