Abstract
Description
Technical Field
[0001] This utility model belongs to the field of flaw detection, specifically relating to a wire rope flaw detection device. Background Technology
[0002] Steel wire ropes are widely used in various industries. In some industries involving critical safety, real-time flaw detection is required during use to ensure that the steel wire ropes do not pose any safety hazards. Many steel wire rope flaw detection devices are available on the market, most of which are handheld. The device is fitted onto the steel wire rope, and the handheld device slides along the wire to perform flaw detection.
[0003] In some applications, it is not possible to perform flaw detection on steel wire ropes by hand. If the detection device is fixed in one place, the vibration of the steel wire rope during the winding and unwinding process, especially for thicker steel wire ropes, will exert a large swing force on the detection device, causing damage to the detection device.

[0023] The application scenario in this embodiment includes a wall 7 perpendicular to the ground 9, a window 8 on the wall 7, and an opening 10 on the ground 9. The steel wire rope 2 is pulled diagonally downwards and passes through the window 8 and the opening 10 in sequence, with the steel wire rope 2 at an angle of about 30° to the ground 9.
[0024] like Figure 1-4As shown, this embodiment includes a crossbar 1, a first trolley 3, a flaw detector 4, a second trolley 5, and a connecting rod 6.
[0025] The horizontal bar 1 adopts a U-shaped structure, is placed horizontally, and its two ends are fixed to the walls 7 on both sides of the window 8. In other embodiments, the horizontal bar 1 can also adopt a straight structure, with the horizontal bar 1 placed horizontally on the frame on both sides of the window 8.
[0026] In this embodiment, the first trolley 3 includes a first roller 3b and a first body 3a.
[0027] The first roller 3b also includes a first shaft and an H-shaped grooved wheel sleeved on the first shaft. The H-shaped grooved wheel is collinear with the axis of the first shaft and can rotate relative to the first shaft. The first roller 3b has four rollers arranged in a rectangular shape at its four corners.
[0028] The first body 3a consists of two parallel and symmetrically placed rectangular plates, which are respectively located on both sides of the H-shaped grooved wheel and fixed to both ends of the first roller.
[0029] The four first rollers 3b are located at the four corners of the rectangular plate. Thus, the four first rollers 3b are divided into two groups and located on both sides of the first body 3a respectively. Each group of first rollers 3b clamps the crossbar 1 from top to bottom.
[0030] In this embodiment, the crossbar 1 is made of square tubing, and the shape of the H-shaped grooved wheel corresponds to the crossbar 1, so that the H-shaped grooved wheel can be well locked on the crossbar 1 and can roll freely back and forth on the crossbar 1.
[0031] In other embodiments, the first roller 3b may be provided in one set, three sets, or other quantities.
[0032] In other embodiments, the first roller can be fixed to the H-shaped grooved wheel, and the first roller can be rotatably connected to the first body 3a. Specifically, a bearing connected to the first roller can be provided on the first body 3a.
[0033] In other embodiments, the first body 3a may be directly sleeved onto the crossbar 1 using a sleeve structure.
[0034] In this embodiment, the flaw detector 4 can be a commonly used instrument on the market. The flaw detector 4 is mounted on the wire rope 2 for flaw detection of the wire rope 2.
[0035] The second trolley 5 includes a second roller 5b and a second body 5a.
[0036] The second roller 5b also includes a second roller shaft and a U-shaped grooved wheel sleeved on the second roller shaft. The U-shaped grooved wheel is collinear with the axis of the first roller shaft and can rotate relative to the second roller shaft.
[0037] Four second rollers 5b are arranged in a rectangular shape at the four corners of the second body 5a, which is connected to the flaw detector 4. Thus, the four second rollers 5b are divided into two groups, located on opposite sides of the second body 5a, with each group of rollers 5b clamping the wire rope 2 vertically. The shape of the U-shaped grooved wheel corresponds to the wire rope 2, allowing the U-shaped groove to be well-positioned on the wire rope 2.
[0038] In another embodiment, the second roller 3b may also be provided in only one set, three sets, or other quantities.
[0039] In another embodiment, the second trolley 5 is equipped with four sets of rollers. Each roller set includes a U-shaped body, with a second roller 5b positioned in the middle of the open end of the U-shaped body. The four sets of rollers are arranged in pairs on both sides of the flaw detector 4, and the closed end of the U-shaped body is connected to the flaw detector 4. This structure is simpler, more compact, and easier to connect to the flaw detector 4.
[0040] In this embodiment, the two ends of the connecting rod 6 are hinged to the first trolley 3 and the second trolley 5 respectively. Specifically, coplanar connecting plates 11 are provided on the first trolley 3 and the second trolley 5, and the two ends of the connecting rod 6 are hinged to the two connecting plates 11.
