Description

Technical Field

[0001] The utility model relates to the field of wire rope flaw detection equipment, in particular to a wire rope flaw detector calibration device based on a standard wire rope. Background Art

[0002] Standard wire rope refers to the wire rope produced in accordance with national standards. It is a module made according to standard requirements. It can be processed from a whole piece of material of the same material as the wire rope, or it can be made by manually bundling wire ropes. Because the overall processing of deep holes is difficult and difficult to control. When choosing the method of manually bundling wire ropes to make wire rope modules, it is necessary to choose steel wires of the same material as the standard wire rope, mixed with copper tubes that do not have magnetic conductivity, to form a wire rope module.

[0003] The existing automatic calibration device used for wire rope flaw detection consists of a support mechanism, a speed adjustment wheel, a speed regulator, etc. The function is to automate the calibration work and provide a uniform linear speed for the standard wire rope, so that the standard wire rope can pass through the copper tube of the wire rope module uniformly at the preset speed. At the same time, it drives the speed sensor of the wire rope flaw detector to be calibrated to a standard speed, thereby automatically calibrating the wire rope flaw detector.

[0004] However, in the process of implementing defect detection on wire ropes of different specifications, if the specifications of the standard wire rope change, the calibration device cannot closely adapt to the wire ropes of different specifications. The wire rope flaw detector is prone to shaking during movement, which affects the stability of the wire rope flaw detector and easily causes unnecessary friction and collision to the wire rope, affecting the efficiency of the detection work. Utility Model Content

[0005] In view of the above problems, the present application provides a wire rope flaw detector calibration device based on a standard wire rope.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a wire rope flaw detector calibration device based on a standard wire rope, comprising an openable and closable connecting body 1, a connecting body 2 and a flaw detector arranged on the connecting body 1, when the connecting body 1 and the connecting body 2 are connected in a closed state, a channel for the wire rope to pass through is formed, the connecting body 1 and the connecting body 2 are respectively provided with a limit guard plate 1 and a limit guard plate 2, the limit guard plate 1 and the limit guard plate 2 are both provided with a clamping roller that can roll in contact with the wire rope, both ends of the clamping roller are connected to a follower arm through a rotating shaft, a positioning arm is provided on the side of the follower arm away from the clamping roller, and the clamping roller and the follower arm can move synchronously along the distribution direction of the positioning arm.

[0007] Furthermore, a limit block is provided on the positioning arm, and a channel capable of accommodating the limit block to pass through is provided on the follower arm. When the follower arm moves, the channel moves outside the limit block.

[0008] Furthermore, the positioning arm is penetrated by a positioning joint 1 and a positioning joint 2, and the positioning joint 1 and the positioning joint 2 extend to the inner side of the channel. In a natural state, the positioning joint 2 abuts against the bottom wall of the channel. When the follower arm moves, the positioning joint 2 moves synchronously, and the distance between the positioning joint 2 and the positioning joint 1 is reduced.

[0009] Furthermore, both the first and second positioning joints are provided with connecting blocks, and the outer sides of the two connecting blocks distributed from top to bottom are provided with the same limiting sleeve, the limiting sleeve is fixed on the positioning arm, and the two connecting blocks distributed from top to bottom are connected by a pressure spring.

[0011] Furthermore, the ends of the connecting body 1 and the connecting body 2 away from the limiting guard plate 1 and the limiting guard plate 2 are both provided with extension arms, and the extension arms are connected to balancing rollers via a rotating shaft.

[0012] In summary, the technical effects and advantages of the utility model are:

[0013] The clamping rollers in the utility model can adjust the spacing to accommodate steel wire ropes of different specifications. When the clamping rollers are located on the steel wire rope and roll and slide, the connecting body 1 and the connecting body 2 move synchronously, and the flaw detector performs flaw detection operations on the steel wire rope.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example: Reference Figure 1 , Figure 2 A wire rope flaw detector calibration device based on a standard wire rope is shown, comprising an openable and closable connecting body 1, a connecting body 2 and a flaw detector 3 arranged on the connecting body 1. When the connecting body 1 and the connecting body 2 are connected in a closed state, a channel for the wire rope to pass through is formed. A limit guard plate 1 4 and a limit guard plate 2 5 are respectively provided on the connecting body 1 and the connecting body 2. The limit guard plate 1 4 and the limit guard plate 2 5 are both provided with a clamping roller 6 that can roll in contact with the wire rope. Both ends of the clamping roller 6 are connected to a follower arm 7 through a rotating shaft, and a positioning arm 8 is provided on the side of the follower arm 7 away from the clamping roller 6.

[0022] In the actual working process, based on the different specifications of standard wire ropes, in order to ensure the stability of the connecting body 1, the connecting body 2 and the flaw detector 3 during the mobile detection of wire ropes of different specifications, the clamping roller 6 and the follower arm 7 can move synchronously along the distribution direction of the positioning arm 8 to accommodate the entry of wire ropes of different specifications. The connecting body 1, the connecting body 2 and the flaw detector 3 can perform mobile detection operations on the outside of wire ropes of different specifications.

[0023] A limit block 9 is provided on the positioning arm 8, and a channel is provided on the follower arm 7 for accommodating the limit block 9 to pass through. When the follower arm 7 moves, the channel moves outside the limit block 9, and the clamping roller 6 can adjust the height. The clamping rollers 6 arranged upper and lower can adjust the distance between the two to accommodate steel wire ropes of different specifications to pass through.

[0024] like Figure 3 , Figure 4 As shown, the positioning arm 8 is penetrated by a clamping joint 10 and a clamping joint 2 11, which extend to the inner side of the channel. In the natural state, the clamping joint 2 11 abuts against the bottom wall of the channel. When the calibration device needs to dock steel wire ropes of different specifications, as the diameter of the steel wire rope increases, the clamping roller 6 moves under the pressure of the steel wire rope, and the follower arm 7 moves synchronously with the clamping joint 2 11, and the distance between the clamping joint 2 11 and the clamping joint 1 10 is reduced. The clamping roller 6 can clamp steel wire ropes of different specifications. When the clamping roller 6 is located on the steel wire rope and rolls and slides, the connecting body 1 and the connecting body 2 2 move synchronously, and the flaw detector 3 performs flaw detection operations on the steel wire rope.

[0025] like Figure 3 , Figure 4 As shown, both the first clamping joint 10 and the second clamping joint 11 are provided with a connection block 12, and the outer sides of the two connection blocks 12 distributed from top to bottom are provided with the same limiting sleeve 81, and the limiting sleeve 81 is fixed on the positioning arm 8, and the two connection blocks 12 distributed from top to bottom are connected by a pressure spring 13. When the clamping roller 6 moves, the second clamping joint 11 and the connection block 12 connected thereto move synchronously, the pressure spring 13 contracts, and the clamping roller 6 can move smoothly, which is suitable for steel wire ropes of different specifications.

[0026] Under the elastic potential energy of the pressure spring 13, the clamping roller 6 can still fit tightly to the surface of the steel wire rope after adapting to steel wire ropes of different specifications, effectively avoiding the shaking of the connecting body 1 and the connecting body 2 during the movement. While adapting to steel wire ropes of different specifications, it can still maintain the stability of the connecting body 1 and the connecting body 2 during the movement.

[0027] like Figure 3 , Figure 4 As shown, in order to prevent the connection block 12 from being separated from the limiting sleeve 81, causing the locking joint 1 10 and the locking joint 2 11 to fall off, the inner wall of the positioning column head limiting sleeve 81 is provided with a protrusion 811 integrally formed therewith, and the two connection blocks 12 arranged from top to bottom on the inner side of the limiting sleeve 81 are provided with a limiting groove 121 that can accommodate the protrusion 811. In a natural state, the connection between the protrusion 811 and the limiting groove 121 limits the moving direction of the connection block 12, thereby effectively preventing the connection block 12 from being separated from the limiting sleeve 81.

[0028] like Figure 1 As shown, in order to maintain the stability of the connecting body 1 and the connecting body 2 during movement, supporting forces are provided at both ends of the connecting body 1 and the connecting body 2, and an extension arm 14 is provided at one end of the connecting body 1 and the connecting body 2 away from the limiting guard plate 4 and the limiting guard plate 2 5. The extension arm 14 is connected to a balancing roller 15 through a rotating shaft. As the connecting body 1 and the connecting body 2 move, the balancing roller 15 supports the stable sliding of the connecting body 1 and the connecting body 2 at one end of the connecting body 1 and the connecting body 2 away from the clamping roller 6.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
