Description

Technical Field

[0001] The utility model belongs to the field of testing of wire rope flaw detectors, and particularly relates to a low-speed testing device for a wire rope flaw detector, which is applicable to the low-speed testing scenario of a wire rope flaw detector. Background Art

[0002] A wire rope flaw detection device is a computerized non-destructive testing instrument used for quantitatively detecting defects such as surface or internal broken wires, wear, corrosion, and rope diameter changes in a wire rope. It is usually divided into an upper half structure and a lower half structure, and the two are opened and closed up and down through a hinge, and the wire rope can pass through a hollow annular groove.

[0003] At present, the devices used to provide a testing scenario for a wire rope flaw detection device are generally large-sized and high-speed devices. The main structural forms are annular wire ropes and linear wire ropes. Generally, in the case of higher wire rope speed requirements, an annular wire rope is adopted, and a motor drives a driving wheel to drive the wire rope to move along a driven wheel together to achieve the high-speed movement of the wire rope. This kind of device has high requirements for the installation environment, is bulky, heavy, and has a certain degree of danger. In addition, the larger the diameter of the annular wire rope, the larger the diameters of the driving and driven wheels of the device. For testing wire ropes of various different specifications, unless the device can cover the thickest wire rope, the applicable wire rope diameters are relatively limited. For the linear wire rope testing environment device, generally, to provide a high-speed testing scenario, the overall length of the device is relatively long. In addition, if high-speed testing is to be achieved, usually the overall device is heavy or needs to be fixed to the ground through expansion bolts. The above two schemes are both applicable to the high-speed testing environment of mature products, and the overall supply cycle is relatively long, and they are not applicable to the low-speed testing environment in the initial stage of product research and development.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0036] It should be noted that when a component is referred to as being "connected" to another component, it can be directly connected to the other component or there can also be an intermediate component; when a component is referred to as being "fixed" to another component, it can be directly fixed to the other component or there can also be an intermediate component.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the specification of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0038] As Figure 1 shown, this embodiment provides a low-speed test device for a wire rope flaw detector, which is applicable to the low-speed test scenario of a wire rope flaw detector, and includes a main body frame 1, a sliding mechanism 2, a height adjustment mechanism 3, a wire rope 5, and a fixing mechanism 6.

[0039] The main body frame 1 provides a stable and reliable support base for the entire low-speed test environment. Therefore, on the premise of meeting the requirement of providing support, the specific structure of the main body frame 1 is not limited in this embodiment. For example, the main body frame 1 in this embodiment is of a cuboid structure, and the cuboid structure is welded by square steel pipes and rectangular pipes. The main body frame 1 is empty except for the pipe body, so as to reduce the overall equipment quality and facilitate the installation of other mechanisms.

[0040] This embodiment of the main body frame 1 provides two side-by-side arranged installation planes, one of which is used as the first position and the other is used as the second position. The first position and the second position provide two installation positions for installing corresponding mechanisms. Taking Figure 1 the orientation shown as a reference, the first position of this embodiment is the bottom of the main body frame 1, and the second position is the top of the main body frame 1.

[0041] As Figure 2As shown, the sliding mechanism 2 is installed at the first position of the main frame 1 to provide a sliding plane and a sliding path in the first direction within the sliding plane. The sliding mechanism 2 includes a slide rail 24, a slider 23, and a sliding fixing plate 21. The slide rail 24 provides a sliding path in the first direction. A plurality of slide rails 24 are arranged side by side, and at least one slider 23 is assembled on each slide rail 24. The slider 23 can freely slide along the length direction of the slide rail 24, and the sliding fixing plate 21 is installed on the slider 23. In this embodiment, two slide rails 24 are arranged side by side. The plane where the two slide rails 24 are located is regarded as the sliding plane, and one slider 23 is installed on the slide rail 24, that is, two sliders 23 are provided in this embodiment, and the sliding fixing plate 21 is jointly installed on the two sliders 23. The sliding fixing plate 21 and the two sliders 23 are fixedly connected by eight fixing screws 22.

[0042] In this embodiment, in order to facilitate the installation of the slide rail 24, a reinforcing member is installed at the bottom of the main frame 1, that is, Figure 1 the horizontal short pipe body located at the bottom of the main frame 1. The slide rail 24 is installed on the reinforcing member of the main frame 1 by screws.

[0043] The height adjustment mechanism 3 is installed on the sliding mechanism 2 to provide a degree of freedom of adjustment in the second direction, and the second direction is perpendicular to the sliding plane. As Figure 3 shown, the height adjustment mechanism 3 includes a telescopic structure and an upper support frame 31. The telescopic structure is connected to the sliding mechanism 2, one end of the upper support frame 31 is connected to the telescopic structure, and the other end is connected to the wire rope flaw detector 4. Among them, the upper support frame 31 is Ω-shaped, and the top of the Ω shape is a plane and is connected to the wire rope flaw detector 4.

[0044] The telescopic structure is mainly used to provide a degree of freedom of adjustment in the second direction. The structure of this embodiment is not limited thereto. For example, a telescopic rod, a telescopic arm, a telescopic shaft, etc. can be directly used. And the second direction being perpendicular to the sliding plane can be understood as the second direction being directly perpendicular to the sliding plane, or it can be understood that the telescopic direction of the telescopic structure has a second direction component perpendicular to the sliding plane.

[0045] This embodiment provides a telescopic structure including a bolt 35, an upper nut 32, a middle nut 33, and a lower nut 34. It is fixed on the sliding mechanism 2 by the bolt 35 and the lower nut 34, and the bolt 35 passes through the outer flanges on both sides of the Ω shape of the upper support frame 31 and is limited at the penetrating part by the upper nut 32 and the middle nut 33. The bolt 35, the upper nut 32, and the middle nut 33 cooperate to provide a degree of freedom of adjustment in the second direction.

[0046] In order to reduce the overall mass of the device of the present utility model, the height adjustment of the wire rope flaw detector 4 can be achieved through the cooperation of bolts and nuts in this application. The hexagonal bolt passes through the sliding fixing plate 21 in the sliding mechanism 2 and the outward-turned edge of the upper support frame 31, and is fixed at the position passing through the sliding fixing plate 21 by the lower nut 34, and is limited at the threaded section position passing through the outward-turned edge by the upper nut 32 and the middle nut 33. During use, adjusting the positions of the upper nut 32 and the middle nut 33 can achieve the height adjustment of the wire rope flaw detector 4. To improve the stability, four hexagonal bolts are used for connection in this embodiment.

[0047] The wire rope 5 is installed at the second position of the main body frame 1 through the fixing mechanism 6, and the extension path of the wire rope 5 corresponds to the sliding path. The height adjustment mechanism 3 is located between the first position and the second position. During the test of the wire rope flaw detector 4, the shape of the wire rope 5 can be linear, circular or arc-shaped, as long as the extension path of the wire rope is kept corresponding to the sliding path.

[0048] As Figure 4 shown, the fixing mechanism in this embodiment includes an upper fixing member 61 and a lower fixing member 63. The lower fixing member 63 is fixed to the main body frame 1 by screws. The upper fixing member 61 is detachably installed on the lower fixing member 63. After the upper fixing member 61 and the lower fixing member 63 are installed, a fixing hole 64 for installing the wire rope is formed between them. To improve the adaptability of the device of the present utility model to the wire rope, the upper fixing member 61 and the lower fixing member 63 are detachably connected by the hexagon socket head cap screw 62 in this embodiment. The wire rope 5 passes through the middle of the upper fixing member 61 and the lower fixing member 63 and is fixedly connected by the hexagon socket head cap screw 62, so as to clamp and fix the wire rope.

[0049] The wire rope flaw detector 4 is installed on the height adjustment mechanism 3. The wire rope flaw detector 4 is fixedly connected to the upper support frame 31 by four screws. This embodiment takes a conventional wire rope flaw detector as an example for illustration. The wire rope flaw detector 4 is divided into an upper half structure 42 and a lower half structure 43, and the two are opened and closed up and down through a hinge. When the upper half structure 42 and the lower half structure 43 are closed, a hollow annular groove 41 is formed between them. During the test, the wire rope 5 passes through the hollow annular groove 41 of the wire rope flaw detector 4.

[0050] When the equipment of the present utility model is in use, the steel wire rope 5 passes through the steel wire rope flaw detector 4 through the hollow annular groove 41. The steel wire rope 5 is manually tightened, and the steel wire rope 5 is pressed by the fixing mechanisms 6 at both ends to realize the tensioning and fixing of the steel wire rope 5. The steel wire rope flaw detector 4 is fixedly connected to the upper support frame 31, the upper support frame 31 is fixedly connected to the sliding fixed plate 21, the sliding fixed plate 21 is fixedly connected to the slider 23, and the slider 23 can freely slide along the length direction of the slide rail 24, so as to realize the free sliding of the steel wire rope flaw detector 4 along the length direction of the steel wire rope 5. At the same time, the height adjustment of the steel wire rope flaw detector 4 can be realized by adjusting the four groups of upper nuts 32 and middle nuts 33 of the height adjustment mechanism 3. Rotating the four groups of upper nuts 32 and middle nuts 33 clockwise can lower the position of the steel wire rope flaw detector 4 in the vertical direction. On the contrary, the position of the steel wire rope flaw detector 4 rises in the vertical direction. By adjusting the height position of the steel wire rope flaw detector 4, the steel wire rope 5 to be measured is made to be located as much as possible in the middle position of the hollow annular groove 41 to reduce the resistance when the steel wire rope flaw detector 4 slides along the steel wire rope 5. For steel wire ropes 5 or wire bundles with different diameters that need to be replaced, only eight hexagon socket head cap screws 62 on the fixing mechanisms 6 on both sides need to be loosened, the existing steel wire rope 5 is removed, and the steel wire rope to be measured is inserted through one end of the fixing mechanism, passed through the hollow annular groove 41 of the steel wire flaw detector 4, and then to the fixing mechanism 6 at the other end. After manually tightening the steel wire rope 5 at both ends, the eight hexagon socket head cap screws 62 are locked to realize the tensioning and fixing of the current steel wire rope 5 to be measured.

[0051] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0052] The above-described embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the appended claims.
