Description

Technical Field

[0001] The present application relates to the technical field of auxiliary tools for wire rope detection equipment, and in particular to a device for detecting damage to a mining hoisting wire rope. Background Art

[0002] Industrial production, tourism, coal mining, shipbuilding and daily lifting and hoisting usually use wire ropes as traction, load-bearing and connection parts. Long-term use of wire ropes under heavy loads is prone to wire breakage, looseness and wear. Use in harsh environments will cause wire ropes to corrode and shrink in diameter, reduce load-bearing capacity, and easily cause safety accidents, endangering personal safety and equipment safety. Therefore, real-time monitoring of wire rope damage prediction and realization of wire rope fast non-destructive automatic detection technology have important social and economic benefits.

[0003] In the related art, wire rope damage detection generally adopts a wire rope flaw detector, which is manually operated by an operator. However, during the operation, the operator needs to hold the wire rope flaw detector throughout the detection. Therefore, during the long operation of the operator, unstable operation may occur to a certain extent, resulting in poor contact between the wire rope and the wire rope flaw detector, thereby causing damage to the wire rope flaw detector. Utility Model Content

[0004] In order to reduce the damage to the wire rope flaw detector, the present application provides a mining hoist wire rope damage detection device.

[0007] By adopting the above technical solution, when testing the wire rope, the wire rope is first passed through the limit assembly, and then through the detection hole of the wire rope flaw detector. When testing the wire rope, the limit assembly can reduce the shaking of the wire rope during the detection process and increase the stability of the wire rope, thereby reducing the poor contact between the wire rope and the wire rope flaw detector, and further reducing the damage to the wire rope flaw detector.

[0009] By adopting the above technical solution, when testing the wire rope, the wire rope is first passed through the position where the two limit wheels are close to each other, and then the wire rope is passed through the detection hole of the wire rope flaw detector for testing.

The rotation of the driving gears causes the two rotating rods to rotate, thereby causing the two limiting wheels to rotate in opposite directions at the same speed. When the wire rope is placed at one end close to the two limiting wheels, the two limiting wheels can transmit the wire rope, reducing manpower consumption.

[0019] By adopting the above technical solution, when the device is moved, the pull rod can be pulled to rotate the universal wheel, thereby moving the device and increasing the flexibility of the device.

[0020] Optionally, the two inclined rods are fixedly connected to a support rod, and one end of the support rod away from the inclined rod is fixedly connected to the base.

[0024] 2. When testing the wire rope, first pass the wire rope through the position where the two limit wheels are close to each other, and then pass the wire rope through the detection hole of the wire rope flaw detector for testing.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1 -Attached Figure 2 This application is described in further detail.

[0030] The present application embodiment discloses a device for detecting damage to a mining hoisting wire rope 4. Figure 1 The detection device includes a base 1, on which two support frames 2 are arranged. The support frame 2 includes a vertical rod 21 fixedly connected to the base 1. The length direction of the vertical rod 21 is perpendicular to the base 1. The end of the vertical rod 21 away from the base 1 is fixedly connected to a cross rod 22. A wire rope flaw detector 3 is fixedly connected to the ends of the two cross rods 22 close to each other. The wire rope 4 passes through the detection hole of the wire rope flaw detector 3. Limiting components 5 for reducing the shaking of the wire rope 4 are arranged on both sides of the wire rope flaw detector 3.

[0031] When testing the wire rope 4, first pass the wire rope 4 through one of the limit components 5, then through the detection hole of the wire rope flaw detector 3, and finally through the other limit component 5. The wire rope 4 is limited by the two limit components 5, thereby reducing the shaking of the wire rope 4 in the process of passing through the wire rope flaw detector 3, thereby reducing the possibility of poor contact between the wire rope 4 and the wire rope flaw detector 3, reducing the damage to the wire rope flaw detector 3 during the detection process, and increasing the service life.

[0032] Reference Figure 1 and Figure 2 Two support plates 23 are fixedly connected to the base 1, and the two support plates 23 correspond to each other. The limit assembly 5 includes a rotating rod 51 rotatably connected between the two support plates 23. There are two rotating rods 51 and they are distributed in parallel up and down. The length direction of the rotating rod 51 is perpendicular to the support plate 23. The two rotating rods 51 are fixedly connected to the limit wheels 52. The axis of the limit wheel 52 coincides with the axis of the rotating rod 51. A limit groove 521 is provided on the limit wheel 52 along the circumference of the limit wheel 52, and the position where the two limit wheels 52 are close to each other is at the same height as the detection hole of the wire rope flaw detector 3.

[0033] When testing the steel wire rope 4, first pass the steel wire rope 4 through the limiting groove 521 between the two limiting wheels 52, then pass the steel wire rope 4 through the detection hole of the wire rope flaw detector 3, and finally pass the steel wire rope 4 through the limiting grooves 521 of the other two limiting wheels 52. The upper and lower limiting wheels 52 can have a certain clamping effect on the steel wire rope 4, and the limiting grooves 521 on the limiting wheels 52 can limit the steel wire rope 4, thereby increasing the stability of the steel wire rope 4 during the detection process.

[0034] Reference Figure 1 and Figure 2 A driving assembly 6 is provided on both sides of the support plates 23 away from each other. The driving assembly 6 includes a driving motor 61 fixedly connected to the side of the two support plates 23 away from each other. The output shaft of the driving motor 61 passes through the support plate 23 and is fixedly connected to one of the rotating rods 51. The axis of the rotating rod 51 coincides with the output shaft of the driving motor 61. One end of the two rotating rods 51 away from the support plate 23 where the driving motor 61 is located passes through the other support plate 23 and is fixedly connected with a driving gear 62. The axis of the driving gear 62 coincides with the axis of the rotating rod 51, and the two driving gears 62 are meshed.

[0035] When the drive motor 61 is started, the drive motor 61 rotates and drives the connected rotating rod 51 to rotate. The rotation of the rotating rod 51 causes the two driving gears 62 to rotate, thereby driving the other rotating rod 51 to rotate, and then causing the two limiting wheels 52 to rotate in opposite directions at the same time. When the wire rope 4 is placed between the two limiting wheels 52, the two limiting wheels 52 rotate in opposite directions to drive the wire rope 4 to move, reducing the steps of manual operation, saving human resources, and at the same time reducing the damage to the wire rope flaw detector 3 caused by manual operation.

[0036] Reference Figure 1 Four universal wheels 24 are fixedly connected to the side of the base 1 away from the support plate 23, and the universal wheels 24 are located at the four corners of the base 1. Two inclined rods 7 are fixedly connected to the side of the base 1 away from the universal wheels 24. The two inclined rods 7 are located on the same side of the limiting assembly 5, and the angle between the two inclined rods 7 and the base 1 is an acute angle. A pull rod 8 is fixedly connected to the end of the inclined rod 7 away from the base 1, and both ends of the cross bar 22 are fixedly connected to the ends of the two inclined rods 7 away from the base 1. Support rods 9 are fixedly connected to the two inclined rods 7, and the ends of the support rods 9 away from the inclined rods 7 are fixedly connected to the base 1, and the support rods 9 are perpendicular to the base 1.

[0037] When the device needs to be moved, the operator can pull the pull rod 8 to rotate the universal wheel 24 to move the device. The universal wheel 24 and the pull rod 8 can facilitate the movement of the entire device, increasing the flexibility of the device. The support rod 9 can increase the stability of the inclined rod 7, thereby increasing the stability of the device during movement.

[0038] The implementation principle of a damage detection device for a mining hoisting wire rope 4 in an embodiment of the present application is as follows: when detecting the wire rope 4, first pass the wire rope 4 through the limiting grooves 521 of two of the limiting wheels 52, then pass it through the detection hole of the wire rope flaw detector 3, and finally pass the wire rope 4 through the limiting grooves 521 of the other two limiting wheels 52, start the drive motor 61, and the drive motor 61 drives the limiting wheels 52 to rotate in the same speed and in the opposite direction, so that the steel wire is transmitted by the limiting wheels 52, reducing the manual operation steps, and the mutual cooperation of the two limiting wheels 52 can limit the wire rope 4, reduce the poor contact between the wire rope 4 and the wire rope flaw detector 3, thereby reducing the damage to the wire rope flaw detector 3, and when the detection of the wire rope 4 is completed, the device as a whole can be moved by pulling the pull rod 8 to increase the flexibility of the device.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
