Description

Technical Field

[0001] This invention application relates to the field of testing equipment technology, and in particular to a wire rope testing device. Background Technology

[0002] As an important industrial product, wire rope faces various safety issues during use, including wear and breakage risks, failure due to overload, corrosion and rust, improper installation and maintenance, fatigue damage and aging, the effects of temperature changes, improper operation, and lack of regular inspection. Wire rope is a crucial component in lifting equipment, and it is exposed to the elements. Currently, wire rope inspection can be performed using specialized wire rope inspection devices to detect damage. However, these devices need to be permanently fixed at the inspection location after installation. Regardless of whether inspection is required, the vibration and friction generated by the wire rope's movement can affect the inspection device, leading to inaccurate data and a shortened lifespan. An automatic wire rope loading and unloading device suitable for wire rope inspection can automatically open the device when not in use, thus extending its service life. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a wire rope testing device that solves the problem that prolonged friction of the wire rope after installation can affect the service life of the testing device.

[0004] According to an embodiment of this utility model, a wire rope detection device includes a detection component, a drive component, two sliding plates, a plurality of first guide rods, a plurality of second guide rods, and a base plate. The base plate is horizontally arranged, and the two sliding plates are parallel to each other and vertically arranged on the top surface of the base plate. The bottom of the sliding plates is slidably connected to the base plate, and the sliding directions of the two sliding plates are opposite. The drive component is fixedly connected to the base plate and the sliding plates, and the drive component is used to drive the two sliding plates to move closer or separate. The first guide rods are symmetrically arranged on opposite sides of the two sliding plates and rotatably connected to the sliding plates. The first guide rods are in a vertical state. The second guide rods are horizontally arranged tapered structures, with the axis of the second guide rods perpendicular to the sliding plates. The large ends of the second guide rods are rotatably connected to the two sliding plates, and the second guide rods correspond to the positions of the first guide rods in the vertical direction. The detection component is fixedly connected to the two sliding plates respectively, and performs flaw detection on the wire rope when the detection component is closed.

[0005] The technical principle of this utility model is as follows: when the driving component causes the two sliding plates to come together, the detection component closes to detect the wire rope. At the same time, the two first guide wheels limit the wire rope on the left and right sides, and the second guide rod moves laterally. The wire rope is restricted in the vertical direction by the two second guide rods.

[0006] Preferably, the driving assembly includes two motors and two screws. The two screws are horizontally arranged on the top surface of the substrate and coaxial. Four support blocks are provided on the top of the substrate. The two ends of the screws are rotatably connected to the support blocks. The sliding plate is threadedly connected to the screws. The motors are fixedly arranged on the top surface of the substrate and are used to drive the screws to rotate. The sliding plate is slidably connected to the substrate.

[0007] Preferably, a sliding base is fixedly provided at the bottom of the sliding plate, and a sliding groove is provided on the base plate, wherein the sliding base and the sliding groove are adapted to each other.

[0008] Preferably, a cover plate is rotatably provided on the top edge of the two sliding plates, and the two cover plates are rotatably connected to the side away from the sliding plates.

[0009] Preferably, the substrate is provided with an outer cover, and the motor is disposed inside the outer cover.

[0010] Preferably, the detection component includes an ultrasonic transmitter and an ultrasonic receiver, which are respectively fixed on the two sliding plates and positioned opposite each other.

[0011] Preferably, a positioning rod is fixedly provided at the small end of the second guide rod, and a sliding through hole is provided on the sliding plate, wherein the positioning rod and the sliding through hole are adapted to each other.

[0012] Compared with existing technologies, this invention has the following advantages: The invention has a simple and reliable structure. The horizontal movement of the sliding plate by the driving component allows the detection assembly to approach the wire rope for inspection. Simultaneously, the first and second guide rods on the sliding plate limit the position of the wire rope in the horizontal and vertical directions, preventing the wire rope from swaying.

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1 As shown in the figure, this utility model embodiment proposes an automatic wire rope detection device, including a detection component, a drive component, two sliding plates 3, a plurality of first guide rods 4, a plurality of second guide rods 8, and a base plate 13. The base plate 13 is horizontally arranged, and the two sliding plates 3 are parallel to each other and vertically arranged on the top surface of the base plate 13. The bottom of the sliding plates 3 is slidably connected to the base plate 13, and the sliding directions of the two sliding plates 3 are opposite, that is, the two sliding plates 3 slide relative to each other. The drive component is fixedly connected to the base plate 13 and the sliding plates 3, and the drive component is used to drive the two sliding plates 3 to move closer or separate. The first guide rods 4 are respectively symmetrically arranged on the opposite side of the two sliding plates 3 and rotatably connected to the sliding plates 3. The first guide rods 4 are in a vertical state, and two connecting rods are fixedly arranged on the sliding plates 3. The connecting rods are rotatably connected to the upper and lower ends of the first guide rods 4. The second guide rod 8 is a horizontally arranged conical structure. The axis of the second guide rod 8 is perpendicular to the sliding plate 3. The large ends of the two second guide rods 8 are rotatably connected to the two sliding plates 3 respectively. The second guide rod 8 corresponds to the vertical position of the first guide rod 4, preventing the wire rope 10 from moving away from the first guide rod 4 in the vertical direction. When the first guide rod 4 limits the wire rope 10 on the X-axis, the second guide rod 8 limits the wire rope 10 on the Y-axis. The detection component is fixedly connected to the two sliding plates 3 respectively. When the two sliding plates 3 are close together, the wire rope 10 is subjected to flaw detection. In this embodiment, the base plate 13 is provided with screw through holes, and the base plate 13 is fixed to the mechanical equipment using the wire rope 10 using screws. When the two sliding plates 3 are close together, the small end of the second guide rod 8 approaches the wire rope 10 first, and the end of the second guide rod 8 does not press against the wire rope 10. Several first guide rods 4 and second guide rods 8 are arranged along the axial direction of the wire rope 10, and the detection device is fixedly installed on the sliding plate 3 at the interval between the two first guide rods 4. The wire rope 10 is arranged between the two first guide rods 4 and also between the two second guide rods 8.

[0018] Preferably, the driving assembly includes two motors 1 and two screws 2. The two screws 2 are horizontally and coaxially arranged on the top surface of the substrate 13. Four support blocks 11 are provided on the top of the substrate 13. The two ends of the screws 2 are rotatably connected to the support blocks 11. In this embodiment, the two ends of the screws 2 are smooth sections without threads, and the support blocks 11 create a gap between the screws 2 and the top surface of the substrate 13. The sliding plate 3 is threadedly connected to the screws 2. The motors 1 are fixedly arranged on the top surface of the substrate 13 and are used to drive the screws 2 to rotate. The sliding plate 3 is slidably connected to the substrate 13. The screws 2 and the sliding plate 3 are perpendicular. The motors 1 control the forward or reverse rotation of the screws 2, thereby causing the two sliding plates 3 to move closer or further apart.

[0019] Preferably, a slide block 14 is fixedly provided at the bottom of the sliding plate 3, and a sliding groove is provided on the base plate 13. The slide block 14 and the sliding groove are adapted to each other, making the sliding plate 3 more stable when moving. After long-term use, the first guide rod 4 and the second guide rod 8 on the sliding plate 3 can still maintain their relative positions when limiting the wire rope 10. When the slide block 14 moves within the sliding groove, it reduces the wear on the screw 2 caused by deviation or movement.

[0020] Preferably, a cover plate 9 is rotatably mounted on the top edge of each of the two sliding plates 3, and the two cover plates 9 are rotatably connected to each other on the side away from the sliding plates 3. The cover plates 9 can prevent or reduce the corrosion of various components by external rainwater, thus extending their service life. When the two sliding plates 3 move away from each other, the included angle between the cover plate 9 and the rotatably connected sliding plates 3 decreases. The rotation of the motor 1 causes the two sliding plates 3 to stop rotating when they are spaced a certain distance apart, thus avoiding motion interference caused by the sliding plates 3 continuing to move when the two cover plates 9 have rotated to 100 degrees. In this embodiment, the motor 1 is a stepper motor with a controller.

[0021] Preferably, the base plate 13 is provided with an outer cover, and the motor 1 is disposed inside the outer cover. Since this device is installed on an outdoor equipment, this avoids the impact of rain on the lifespan of the motor 1.

[0022] Preferably, the detection component includes an ultrasonic transmitter 6 and an ultrasonic receiver 7, which are respectively fixed on the two sliding plates 3 and positioned opposite each other. In this embodiment, the ultrasonic transmitter 6 emits electromagnetic waves. When ultrasonic waves propagate in the material being tested, the acoustic properties and changes in the internal structure of the material have a certain impact on the propagation of the ultrasonic waves. The technique of understanding the material properties and structural changes by detecting the degree and condition of the impact on the ultrasonic waves is called ultrasonic testing.

[0023] Preferably, a positioning rod 12 is fixedly provided at the small end of the second guide rod 8, and a sliding through hole 5 is provided on the sliding plate 3. The positioning rod 12 and the sliding through hole 5 are adapted to each other. When the second guide rod 8 is above and in contact with the wire rope 10, in order to avoid only one end of the second guide rod 8 being subjected to force, the positioning rod 12 on the second guide rod 8 and the sliding through hole 5 on the opposite sliding plate 3 are made to cooperate to prevent the second guide rod 8 from shifting.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
