Description

Technical Field

[0001] This utility model relates to the field of wire rope testing technology, specifically a wire rope torque testing device. Background Art

[0002] Wire rope is a helical bundle of steel wires that meet specific mechanical properties and geometric dimensions, twisted together according to certain rules. It consists of steel wires, a core, and lubricant. Wire rope is first made by twisting multiple layers of steel wires into strands, and then, with the core as the center, winding a certain number of strands into a helical shape. In material handling machinery, it is used for lifting, traction, tensioning, and load-bearing. Wire rope is characterized by high strength, light weight, smooth operation, and resistance to sudden breakage, ensuring reliable operation.

[0003] Steel wire ropes are generally used in places where they need to withstand large tensile or torsional forces. Steel wire ropes tend to twist when subjected to tension, so tensile and torque tests are required after the steel wire ropes are manufactured. This allows users to make reasonable choices based on their actual usage needs.

[0004] In order to hang the existing test torque device on the hook, a loop needs to be made at the end of the wire rope. Making the loop at the end of the wire rope requires manual fixation with multiple clamps using tools, which is difficult, cumbersome, and inefficient for measurement and testing. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, this utility model provides a wire rope torque testing device. A person passes the wire rope back and forth through the movable opening of the movable column and the fixed opening of the fixed column. A driving rotating component rotates the movable column, causing the wire rope to rotate. Combined with the constraint of the fixed column on the wire rope, friction is generated between the wire ropes themselves and between the wire rope and the movable and fixed columns, achieving the purpose of fixing. The fixing method is simple, convenient, and quick, improving the efficiency of testing and facilitating disassembly and installation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wire rope torque testing device, comprising a mounting plate, a fixed frame, a pair of fixed columns, a movable column, and a pair of driving rotating components. The mounting plate is fixedly mounted on the top of the fixed frame and is used to fixally connect to the connection end of the torque testing device.

A fixed rod is inserted through each through-hole, and the fixed rod can move relative to the other inside the through-hole. The upper and lower ends of the fixed rod are fixedly connected to the pair of fixed columns respectively. The pair of fixed columns and the movable column are vertically arranged, and the upper fixed column is fixedly connected to the bottom of the fixed frame. A pair of driving rotating components are located on both sides of the bottom of the fixed frame, and the driving rotating components can drive the movable column to rotate around its axis. The upper and lower end faces of the pair of fixed columns have elliptical fixed openings that can accommodate two strands of wire rope at their center positions. The upper and lower end faces of the movable column have movable openings that match the fixed openings at their center positions.

[0007] Preferably, the upper end face of the upper fixing column is provided with an arc-shaped guide plate, and the inner side wall is provided with a guide groove, the two ends of the guide groove respectively corresponding to the long axis side of the elliptical fixing opening.

[0008] Preferably, the upper end face of the upper fixing column is provided with a teardrop-shaped clamping plate with the tip pointing downwards, and the clamping plate spans the short axis side of the elliptical fixing opening.

A fixed rod 10 is installed through each through-hole 6, and the fixed rod 10 can move relative to each other within the through-hole 6.

The pair of fixed columns 15 and the movable column 8 are vertically arranged, and the upper fixed column 15 is fixedly connected to the bottom of the fixed frame 1. A pair of driving rotating components are arranged on both sides of the bottom of the fixed frame 1, and the driving rotating components can drive the movable column 8 to rotate around its axis. The upper and lower end faces of the pair of fixed columns 15 have elliptical fixing holes 13 that can accommodate two strands of wire rope at their center positions. The upper and lower end faces of column 8 have movable openings 9 that match the fixing opening 13 at their center positions; the upper end face of the upper fixing column 15 is provided with an arc-shaped guide plate 16, and the inner side wall is provided with a guide groove 2, the two ends of which correspond to the major axis side of the elliptical fixing opening 13; the upper end face of the upper fixing column 15 is provided with a teardrop-shaped clamping plate 3 with its tip pointing downwards, the clamping plate 3 spans the minor axis side of the elliptical fixing opening 13; the driving rotating component includes a motor 4, a gear 7 and an external gear ring 11, the motor 4 and the bottom of the fixing frame 1 The gear 7 is fixedly connected to the output end of the motor 4, and the external gear ring 11 is fixedly sleeved on the outer side wall of the movable column 8. The gear 7 and the external gear ring 11 are meshed together. The sliding component includes multiple fixed plates 14, multiple sliders 5 and a pair of sliding grooves 12. The multiple fixed plates 14 are respectively disposed on the upper end face and the lower end face of the movable column 8. The multiple sliders 5 are fixedly connected to the inner side wall of the fixed plates 14. The sliders 5 are respectively opened around the outer side wall of the pair of fixed columns 15. The sliders 5 are slidably connected to the sliding grooves 12.

[0020] Its detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, as follows:

[0021] According to the instruction manual Figure 1-3As can be seen, in the operation of this utility model, one end of the steel wire rope is inserted from the lower fixed port 13 side, passes through the movable port 9 and the upper fixed port 13, then bends and enters again from the upper fixed port 13, passes through the movable port 9, and finally exits from the lower fixed port 13 side. In this way, a double-strand steel wire rope is formed in the fixed port 13 and the movable port 9. At this time, the drive rotating component works, driving the movable column 8 to rotate. Since the movable port 9 and the fixed port 13 are elliptical in shape, the range of motion of the two steel wire ropes is limited. The optimal shape is the shape of the playground track. Therefore, the rotation of the movable column 8 can drive the steel wire rope at this point to rotate, thereby generating friction between the steel wire ropes and between the steel wire rope and the movable column 8 and the fixed column 15, achieving the purpose of fixing. The fixing method is simple, convenient and quick, improving the efficiency of testing. The drive component rotates to make the movable port 9 and the fixed port 13 correspond vertically, releasing or reducing friction, and then disassembly can be performed. It should be noted that the movable column 8 does not need to rotate at a large angle. A pair of fixed columns 15 are fixedly connected by a fixed rod 10. The fixed rod 10 passes through the slide 6 and can move within the slide 6 to ensure the normal operation of the movable column 8. The sliding component ensures the stability of the rotation of the movable column 8.

[0022] The upper end of the fixed column 15 is provided with an arc-shaped guide plate 16, and the inner side wall is provided with a guide groove 2. The two ends of the guide groove 2 correspond to the long axis side of the elliptical fixed port 13. When the wire rope is inserted, the guide plate 16 guides the wire rope through the guide groove 2, so that it can bend and rotate to be inserted into the fixed port 13 and the movable port 9 for a second time, which facilitates personnel operation and improves installation efficiency.

[0023] The upper end of the fixed column 15 is provided with a teardrop-shaped clamping plate 3 with the tip pointing downwards. The clamping plate 3 spans the short axis of the elliptical fixed opening 13. The teardrop-shaped clamping plate 3 with the tip pointing downwards can guide the entry of the wire rope, and the two wire ropes can be wrapped around it to prevent the wire rope from slipping out of the fixed opening 13 and the movable opening 9.

[0024] The driving rotating component includes a motor 4, a gear 7, and an external gear ring 11. The motor 4 is fixedly connected to the bottom of the fixed frame 1, the gear 7 is fixedly connected to the output end of the motor 4, and the external gear ring 11 is fixedly sleeved on the outer wall of the movable column 8, with the gear 7 meshing with the external gear ring 11. During operation, the motor 4 rotates, driving the gear 7 to rotate, which in turn drives the external gear ring 11 and the movable column 8 to rotate. The driving method is simple, the motor 4 can rotate in both directions, and it has a self-locking function. Two driving rotating components are designed to improve the fixing strength and stability.

[0025] The sliding component includes multiple fixed plates 14, multiple sliders 5, and a pair of sliding grooves 12. The multiple fixed plates 14 are respectively disposed on the upper and lower ends of the movable column 8. The multiple sliders 5 are respectively fixedly connected to the inner sidewall of the fixed plates 14. The sliders 5 are respectively formed around the outer sidewall of the pair of fixed columns 15. The sliders 5 are slidably connected to the sliding grooves 12, making the rotation of the movable column 8 connected to the fixed plates 14 more stable and the force applied to the wire rope more stable.

[0026] This utility model relates to the part of the wire rope fixing device for the test torque device, which is installed at the test end by the mounting plate 17 of the fixing frame 1. Other parts can be installed using existing technology.
