Description

Technical Field

[0001] The utility model relates to a steel wire rope flaw detection device, in particular to a non-destructive flaw detection device for steel wire ropes integrating visual inspection. Background Art

[0002] The steel wire rope is one of the important components connecting the hoisting mechanism of the winch-type sluice hoist. It mainly bears three kinds of forces: tension, bending, and extrusion, and is required to have the characteristics of high strength, large load-bearing capacity, strong overload capacity, good elasticity, and impact resistance. During the daily operation of the sluice, due to various factors (such as wind, sun, soaking in water, dust, cold and heat, long-term load-bearing, etc.), defects and damages such as broken wires, fatigue, wear, and corrosion occur in the steel wire rope during use. Therefore, it is necessary to strengthen inspections, maintenance, and repairs, effectively and timely grasp the operation status of the in-service steel wire rope, prevent and eliminate major hidden dangers, ensure the normal opening and closing of the sluice gate, the safe operation of the project, and avoid potential dangers or accidents caused by poor maintenance.

[0003] Currently, in the daily maintenance work of sluice steel wire ropes, a non-destructive flaw detector is usually used to detect internal broken wires and other problems of the steel wire rope. In order to further detect the external damage of the steel wire rope, a visual inspection device is usually configured. The image acquisition device of the steel wire rope visual inspection equipment usually builds a bracket or platform around the steel wire rope. The installation of the camera is relatively difficult, the installation position is relatively fixed and immovable. Even if a slider guide device is installed under the camera, it can only move in the horizontal direction and cannot adapt to the detection tasks of steel wire ropes of different sizes. When the visual inspection acquires the surface image data of the steel wire rope, it is difficult to obtain relatively uniform light through the surrounding environment, and it is also difficult to overcome the ghosting phenomenon caused by the shaking of the steel wire rope during the shooting process, resulting in ineffective or interfering detection signals, and missing or misjudging the defect damage characteristics. Summary of the Utility Model

[0004] Aiming at the above-mentioned defects of the prior art, the task of the utility model is to provide a non-destructive flaw detection device for steel wire ropes integrating visual inspection, which solves the problems such as the single and fixed installation position of the visual inspection equipment erected on the fixed platform, immovability, camera jitter during the image acquisition process, and inaccurate signal acquisition.

[0005] The technical solution of the utility model is as follows: A non-destructive flaw detection device for wire ropes with integrated visual detection, comprising a non-destructive flaw detector body and a visual detection mechanism, the non-destructive flaw detector body is provided with a wire rope detection channel running through the head and tail, a wire rope guide wheel is provided at the front of the head end of the non-destructive flaw detector body, the visual detection mechanism comprises a mounting base and an image sensor, the mounting base is an annular groove structure, the mounting base is fixed to the tail end of the non-destructive flaw detector body, the annular middle part of the mounting base is a channel opposite to the wire rope detection channel, the groove-shaped opening of the mounting base is arranged toward the channel, a plurality of mounting slot holes are provided on the outer peripheral wall of the mounting base, the mounting slot holes are connected to a shock-absorbing bracket, and the image sensor is mounted on the shock-absorbing bracket and is located in the groove-shaped opening of the mounting base.

[0006] Furthermore, the shock-absorbing bracket includes an arc-shaped spring sheet and a shock-absorbing pad, both ends of the arc-shaped spring sheet are bent to form a connection point, a shock-absorbing pad is provided on the connection point, and the circuit board of the image sensor is connected to the connection point through the shock-absorbing pad.

[0007] Furthermore, an adjusting screw hole is provided at the midpoint of the arc-shaped spring along the arc radial direction, and an adjusting bolt passes through the mounting slot and the adjusting screw hole to connect the shock-absorbing bracket and the mounting base. The image sensor can be moved forward and backward along the radial direction by rotating the adjusting bolt, and always keeps facing the hole of the mounting base, that is, facing the wire rope.

[0008] Furthermore, in order to make it easier for the image sensor to remain parallel during adjustment, the width of the arc-shaped spring piece is equal to the width of the slot-shaped opening of the mounting base. The arc-shaped spring piece is guided by the slot-shaped opening of the mounting base during movement.

[0009] Furthermore, the mounting base is annular, and the mounting slot extends along the circumference of the annular shape of the mounting base.

[0010] Furthermore, in order to facilitate the installation of the shock-absorbing bracket and the image sensor, the installation base is divided into at least two lobes along the circumference of the ring.

[0011] Furthermore, a fill light is provided on the groove-shaped side wall of the mounting base.

[0012] The advantages of the utility model compared with the prior art are:

[0013] The utility model installs the image sensor at the tail of the nondestructive flaw detector body through the installation base, and the visual detection mechanism moves along the wire rope together with the nondestructive flaw detector body. The swinging and shaking of the wire rope will drive the nondestructive flaw detector body and the visual detection mechanism to move together, so that the relative displacement between the visual detection mechanism and the wire rope is reduced, thereby improving the stability of detection.

[0021] The present invention will be further described below in conjunction with the embodiments, but is not intended to limit the present invention.

[0022] Please combine Figures 1 to 6 As shown, the present embodiment involves a nondestructive flaw detection device for wire ropes with integrated visual inspection, including a nondestructive flaw detector body 1 and a visual inspection mechanism 2. The nondestructive flaw detector is a mature product of the prior art. The nondestructive flaw detector body 1 adopts the structure of the existing nondestructive flaw detector, and its specific internal structure is not repeated. The nondestructive flaw detector body 1 is provided with a wire rope inspection channel 101 that runs through the head and tail. The wire rope passes through the wire rope inspection channel 101, and the nondestructive flaw detector body 1 performs flaw detection on the inside of the wire rope. A wire rope guide wheel 102 is provided at the front of the head end of the nondestructive flaw detector body 1, so that the nondestructive flaw detector body 1 can move along the wire rope.

[0023] The visual detection mechanism 2 includes a mounting base 201 and an image sensor 202. The mounting base 201 is an annular groove structure. The mounting base 201 is not necessarily annular. In some embodiments, the top surface and the ground of the mounting base 201 adopt a structure that is approximately a regular hexagon, such as Figure 7 This embodiment adopts a circular ring shape, and in order to facilitate the subsequent installation of the image sensor 202, the mounting base 201 is divided into two lobes, the advantages of the circular ring structure will be described later.

[0024] The annular middle portion of the mounting base 201 is a hole 2011 opposite to the wire rope detection channel 101, that is, after the mounting base 201 is fixed to the rear end of the non-destructive flaw detector body 1, the hole 2011 is aligned with the wire rope detection channel 101. The slot-shaped opening 2013 of the mounting base 201 is arranged toward the hole 2011, and the image sensor 202 is installed in the slot-shaped opening 2013 of the mounting base 201.

[0025] The outer peripheral wall of the mounting base 201 is provided with a plurality of mounting slots 2012, and the mounting slots 2012 are connected with a shock-absorbing bracket, and the shock-absorbing bracket includes an arc-shaped spring piece 203 and a shock-absorbing pad 204. The two ends of the arc-shaped spring piece 203 are bent to form a connection point, and a shock-absorbing pad 204 is provided on the connection point. The shock-absorbing pad 204 is a sponge gasket, and the circuit board of the image sensor 202 is connected to the connection point through the shock-absorbing pad 204, thereby completing the installation of the image sensor 202 and the shock-absorbing bracket. In this way, the vibration transmitted to the image sensor 202 is reduced by the deformation of the arc-shaped spring piece 203 and the sponge gasket, thereby improving stability. The connection between the shock-absorbing bracket and the mounting slot 2012 is such that an adjusting screw hole is opened along the arc radial direction at the midpoint of the arc-shaped spring leaf 203, and the adjusting bolt 205 passes through the mounting slot 2012 and the adjusting screw hole to connect the shock-absorbing bracket and the mounting base 201. The width of the arc-shaped spring leaf 203 is equal to the width of the slot-shaped opening of the mounting base 201, so that when the adjusting bolt 205 is rotated, the shock-absorbing bracket moves along the radial direction of the channel 2011 to adjust the distance between the image sensor 202 and the wire rope.

[0026] The mounting slot 2012 can make the long strip hole extend along the circular circumference of the mounting base 201, and cooperate with the mounting base 201 with the circular structure, so that no matter how the connection position of the shock-absorbing bracket and the mounting slot 2012 is adjusted, the image sensor 202 can be accurately aligned with the center of the channel 2011, and the mounting slot 2012 can facilitate the adjustment of the position of the image sensor 202 in the circumference of the wire rope, so that multiple image sensors 202 can fully capture the circumferential image of the wire rope for visual inspection.

[0027] In addition, in order to ensure sufficient light to obtain high-quality images, the grooved side wall of the mounting base 201 (for example, around the opening of the channel 2011) is provided with a fill light (the fill light is not shown in the drawings), which can be turned on for fill light when the light is insufficient.
