[0001] The utility model relates to the technical field of manufacturing of wind power towers, and particularly relates to a handheld straight probe flaw detection auxiliary device. Background Technique

[0002] Wind power generation is an important form of wind energy utilization. Wind energy is a green energy source that is renewable, pollution-free, has large energy, and broad prospects. Vigorously developing clean energy is a strategic choice for countries around the world. Wind power towers are an important part of the wind power industry and are also the foundation and guarantee for the development of the wind power industry. Countries around the world have taken incentive measures to promote the development of their own wind power technology and equipment industries.

[0003] At present, wind power towers are made by rolling and welding multiple steel plates. According to the technical specifications of major mainframe factories, non-destructive testing must be carried out on the steel plate raw materials. Since in normal work, the probe is held by hand and squatted down for flaw detection, not only is the workload large and the work efficiency is not high, but the body also has to bear a large load. To solve this technical problem, the utility model proposes a handheld straight probe flaw detection auxiliary device. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a handheld straight probe flaw detection auxiliary device, which can effectively solve the problems mentioned in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A handheld straight probe flaw detection auxiliary device includes a flaw detection cylinder, a sliding rod, and a storage cylinder. The sliding rod is movably and penetratingly arranged inside the flaw detection cylinder. A spring is arranged on the outer side of the sliding rod, and one end of the spring contacts the inner wall of the flaw detection cylinder. One end of the sliding rod is provided with a clip, and the clip is an arc-shaped piece. The clip is located inside the flaw detection cylinder. A set of pull rods is movably arranged inside the storage cylinder.

[0007] Preferably, a through hole is penetratingly opened inside the flaw detection cylinder, and two groups of positioning blocks are arranged at the top end of the flaw detection cylinder.

[0008] Preferably, a storage shell is arranged on the outer side of the sliding rod, and a positioning bolt is threadedly penetratingly arranged inside the storage shell.

[0009] Preferably, a moving plate is movably and fittingly arranged inside the storage shell, and rollers are arranged at the bottom end of the moving plate.

[0011] Preferably, a threaded cylinder is provided with external threads on the outer side of the threaded piece, and a protective sleeve is provided on the outer side of the pull rod, and the protective sleeve is made of rubber material.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In the utility model, by providing components such as clamping pieces, storage cylinders and pull rods, since the arc-shaped clamping pieces with springs can clamp straight probes of different sizes, straight probes with different diameters can be placed in the flaw detection cylinder for use. The storage cylinder and the pull rod facilitate the operator to move the auxiliary device by hand. In this way, it is beneficial for the flaw detection personnel to stand and push the straight probe for flaw detection with their bodies. The contact surface between the straight probe and the steel plate increases each time it slides, and the detection time is shortened, thereby increasing the work efficiency and reducing the physical load, which greatly promotes the production progress.

[0014] In the utility model, by providing components such as rollers and threaded cylinders, the moving plate is limited to move up and down through the storage shell, so that the rollers arranged at the bottom end of the moving plate contact and roll with the flaw detection surface, which is convenient for the operator to move the handheld straight probe flaw detection auxiliary device, reducing the labor intensity of the operator. By rotating the threaded cylinder, the threaded cylinder rotates in a threaded manner from the storage cylinder direction to the threaded piece, squeezing the threaded piece close to the pull rod, and being able to squeeze and position the pull rod after adjusting the use length inside the storage cylinder, which is convenient for operators of different heights to use, effectively improving the applicability of the handheld straight probe flaw detection auxiliary device.

[0021] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0022] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, a hand-held straight probe flaw detection auxiliary device;

[0023] It includes a detection cylinder 1, a slide bar 3 and a storage cylinder 12. The slide bar 3 is movably arranged through the inside of the detection cylinder 1. A spring 4 is arranged on the outer side of the slide bar 3, and one end of the spring 4 contacts the inner wall of the detection cylinder 1. One end of the slide bar 3 is provided with a clip 5, and the clip 5 is an arc-shaped piece. The clip 5 is located inside the detection cylinder 1. A set of pull rods 15 are movably arranged inside the storage cylinder 12. A through hole 2 is penetrated and opened inside the detection cylinder 1.

[0024] Two sets of slide bars 3 are symmetrically arranged inside the detection cylinder 1, and springs 4 are arranged on the outer sides of the two sets of slide bars 3. The two ends of the spring 4 respectively contact the set of clips 5 and the inner wall of the detection cylinder 1. By using the elastic action of the springs 4 on the outer sides of the two sets of slide bars 3, the two sets of clips 5 located inside the detection cylinder 1 can be moved closer. Since the clip 5 is designed as an arc-shaped plate, the two sets of clips 5 moving closer can clamp the cylindrical straight probe inside the detection cylinder 1. Because there are arc-shaped clips 5 with springs 4 that can clamp straight probes of different sizes, with this auxiliary device, we can put straight probes of multiple sizes and diameters into the detection cylinder 1 for use. The connecting wire of the straight probe can pass through the through hole 2 opened at the top of the detection cylinder 1 to connect to the flaw detector. Through the storage cylinder 12 and the pull rod 15, it is convenient for the user to hold the auxiliary device and move it. This is beneficial for the flaw detector to stand and push the straight probe for flaw detection. Each time the straight probe slides, the contact surface with the steel plate increases, the detection time is shortened, thereby increasing the work efficiency and reducing the physical load, which has a great promoting effect on the production progress.

[0025] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, a hand-held straight probe flaw detection auxiliary device;

[0026] At the top of the flaw detection cylinder 1, there are two groups of positioning blocks 10. On the outer side of the sliding rod 3, there is a storage shell 6. A positioning bolt 7 is threaded through the interior of the storage shell 6. A moving plate 8 is movably fitted inside the storage shell 6. At the bottom of the moving plate 8, there are rollers 9. A rotating rod 11 is movably passed through the interior of the positioning block 10. A storage cylinder 12 is arranged on one side of the rotating rod 11. At one end of the storage cylinder 12, there is a threaded piece 13. A threaded cylinder 14 is threaded on the outer side of the threaded piece 13. A protective sleeve 16 is arranged on the outer side of the pull rod 15, and the protective sleeve 16 is made of rubber material.

[0027] The flaw detection cylinder 1 is one of the main combined components of a handheld straight probe flaw detection auxiliary device. The positioning blocks 10 are arranged at the top of the flaw detection cylinder 1, and a rotating rod 11 is rotatably arranged inside the two groups of positioning blocks 10. By rotating the rotating rod 11 inside the positioning blocks 10, the storage cylinder 12 and the flaw detection cylinder 1 can rotate 180 degrees forward and backward. The moving plate 8 is movably fitted inside the storage shell 6 through fitting. The storage shell 6 can limit the up and down movement of the moving plate 8. By using the positioning bolt 7, the moving plate 8 after adjusting the use length inside the storage shell 6 can be threadedly squeezed and positioned, so that the rollers 9 arranged at the bottom of the moving plate 8 contact and roll on the flaw detection surface, which is convenient for the user to move the handheld straight probe flaw detection auxiliary device, reducing the labor intensity of the replacement personnel. The threaded piece 13 is made of plastic material. The threaded piece 13 is arranged at one end of the storage cylinder 12 through four groups symmetrically. Then, through the threaded connection between the threaded piece 13 and the inner wall of the threaded cylinder 14, the inner diameter of the threaded cylinder 14 gradually decreases from the storage cylinder 12 towards the pull rod 15 direction. By rotating the threaded cylinder 14, the threaded cylinder 14 is threadedly rotated from the storage cylinder 12 direction to the threaded piece 13, squeezing the threaded piece 13 to approach the pull rod 15, and the pull rod 15 after adjusting the use length inside the storage cylinder 12 can be squeezed and positioned, which is convenient for users of different heights to use, effectively improving the applicability of the handheld straight probe flaw detection auxiliary device. Using the protective sleeve 16 made of rubber material can protect the palm part of the user.

[0028] During use, by stretching the sliding rod 3, the two groups of clamping pieces 5 inside the flaw detection cylinder 1 are separated and moved. Since the arc-shaped clamping pieces 5 with springs 4 can clamp straight probes of different sizes, with this auxiliary device, we can put straight probes of multiple sizes and diameters into the flaw detection cylinder 1 for use. The connecting wire of the straight probe can pass through the through hole 2 opened at the top of the flaw detection cylinder 1 and be connected to the flaw detector. Through the storage cylinder 12 and the pull rod 15, it is convenient for the user to hold the auxiliary device and move. This is beneficial for the flaw detection personnel to stand and push the straight probe for flaw detection with their bodies. Each time the straight probe slides, the contact surface with the steel plate increases, the detection time is shortened, thereby increasing the work efficiency and reducing the body load, which has a great promoting effect on the production progress.

[0029] The movable plate 8 is vertically limited and moved by the storage case 6. The positioning bolt 7 can be used to perform threaded extrusion positioning on the movable plate 8 after adjusting the use length inside the storage case 6, so that the roller 9 provided at the bottom end of the movable plate 8 contacts and rolls on the flaw detection surface, facilitating the operator to move the handheld straight probe flaw detection auxiliary device and reducing the labor intensity of the operator during use and replacement. By rotating the threaded cylinder 14, the threaded cylinder 14 is threaded and rotated from the direction of the storage cylinder 12 to the threaded piece 13, squeezing and approaching the threaded piece 13 to the pull rod 15, and the pull rod 15 after adjusting the use length inside the storage cylinder 12 can be squeezed and positioned, facilitating the use by operators of different heights and effectively improving the applicability of the handheld straight probe flaw detection auxiliary device.
