Description

Technical Field

[0001] The utility model relates to the field of weld detection, in particular to a cross weld detection device for a bridge steel structure. Background Art

[0002] The quality of welds obtained by the welding technology currently used has not yet achieved sufficient stability. Therefore, in order to ensure the quality of welded components, quality inspection of welds must be carried out to ensure that the welds meet the specified technical requirements and the safe use of the structure. Nondestructive testing of welds refers to the use of ultrasonic testing, radiographic testing, magnetic particle testing or penetrant testing to test whether the quality of welds meets the specified requirements and design intent without damaging the performance and integrity of the welds being inspected. The most widely used radiographic testing method currently is to use the penetrating radiation emitted by the radiation source to penetrate the weld and make the film sensitive. The defect image in the weld is displayed on the processed radiographic film, which can detect defects such as pores, slag inclusions, cracks and incomplete penetration in the weld. The existing weld detection device cannot store cables and probes when in use. Cables and probes are easily damaged when exposed to the outside for a long time, affecting the detection accuracy. When inspecting the hanger of the bridge, the staff needs to climb up to inspect, and at this time, the detection device is prone to fall and damage. For this purpose, application number: CN202120317911.2 discloses a cross-intersecting weld detection device for a highway bridge steel structure, which includes: a device body, a storage box, a handle and a hanging ring, a cable is arranged on the top of the right side wall of the device body, a wire reel is arranged in the center of the cable, a probe is arranged at the end of the cable, a storage box is arranged on the right side wall of the device body, a box cover is hinged on the right side wall of the storage box, a handle is arranged on the left side wall of the device body, and a hanging ring is arranged on the left side of the bottom of the device body, so that the cable and the probe can be stored inside the box body to protect the cable and the probe, a wire reel is installed on the cable, which is convenient for cable collection and release, and easy to carry and use, a rope and a lock are arranged at the bottom of the device, and when in use, one end of the rope is hung on the staff and the other end is connected to the device body to prevent the device from falling during high-altitude inspection of the bridge.

[0003] However, the above scheme still has certain defects. The inventors have found through research that in the above scheme, a storage box is provided on the surface of one side of the device body to protect the probe, and a cable reel is provided in the storage box to store the cables. However, the storage box lacks a limiting structure for the probe. The probe may swing freely in the storage box and collide with the inner wall of the storage box, thereby causing damage and affecting the accuracy of device detection.

[0004] How to invent a cross-intersecting weld detection device for bridge steel structures to improve these problems has become an urgent problem to be solved by technical personnel in this field. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a cross-intersecting weld detection device for a bridge steel structure, comprising a mounting base 100, a detection device body 210 is mounted on the mounting base 100, the detection device body 210 is provided with a plurality of wires 220, and a plurality of detection probes 230 are connected correspondingly through the wires 220, the mounting base 100 comprises a bottom plate 110, a slide groove 111 is provided on the upper surface of the bottom plate 110, two relatively arranged clamping blocks 120 are slidably installed in the slide groove 111, one end of a bidirectional threaded rod 112 is rotatably connected to the inner wall of one end of the slide groove 111, a threaded hole 121 is observed on the surface of one end of each clamping block 120, the two clamping blocks 120 are threadedly connected to the two ends of the bidirectional threaded rod 112 through the corresponding threaded holes 121, a plurality of winding posts 130 are arranged on the surface of one side of the bottom plate 110, a plurality of probe buckles 140 for fixing the detection probes 230 are also arranged on the surface of one side of the bottom plate 110, and a handle 150 is arranged on the surface of one end of the bottom plate 110.

[0022] It should be noted that the probe buckle 140 is made of a highly tough deformable material, and a protective rubber pad for increasing friction is provided on its annular inner wall. When it is connected to the detection probe 230 , the annular part is tightly clamped on the outer wall of the detection probe 230 .

[0023] The other end of the bidirectional threaded rod 112 extends to the outside of the bottom plate 110 through a through hole provided on the inner wall of the other end of the slide slot 111 and is fixedly connected to an adjustment knob 113 . A limiting structure is provided between the bidirectional threaded rod 112 and the slide slot 111 .

[0024] The adjustment knob 113 can be provided to facilitate the user to rotate the bidirectional threaded rod 112. Since the two clamping blocks 120 are slidably installed in the slide groove 111 and are threadedly connected to the two ends of the bidirectional threaded rod 112 through the threaded hole 121, when the user rotates the bidirectional threaded rod 112, the two clamping blocks 120 will slide synchronously toward or away from each other, so that the size of the detection device body 210 of different specifications can be adjusted to complete the clamping of the detection device body 210, so that the detection device body 210 and the bottom plate 110 are connected, reducing limitations in use. To improve the adaptability of the detection device body 210 when used with different specifications, at the same time, the limiting structure between the bidirectional threaded rod 112 and the slide groove 111 can be a damping structure or a torsion spring structure. The damping structure can increase the rotation resistance of the bidirectional threaded rod 112 to ensure that the bidirectional threaded rod 112 will not rotate when no external force is applied during use, or the torsion spring structure can make the bidirectional threaded rod 112 under the condition of no external force being applied, so that the two clamping blocks 120 are always in the minimum clamping distance state by the torsion spring force, so as to improve the overall stability during use.

[0025] Furthermore, a back plate 122 is provided on the surface of one side of each clamping block 120 away from the other clamping block 120, and one end of a telescopic rod 123 is fixedly connected to the surfaces of both sides of the back plate 122, and the other end of each telescopic rod 123 is fixedly connected to the surface of one side of the corresponding connecting plate 124, and a tensioning spring 125 is sleeved on the outside of each telescopic rod 123, and the two ends of each tensioning spring 125 are fixedly connected to the corresponding back plate 122 and the surface of one side of the connecting plate 124, and each connecting plate 124 is fixedly connected to a limiting plate 126, and the two limiting plates 126 are located at the two ends of the corresponding clamping block 120 and are arranged opposite to each other.

[0026] Two limit plates 126 are connected at both ends of the clamping block 120 through a telescopic rod 123, and a tensioning spring 125 is sleeved on the outside of the telescopic rod 123 to limit the limit plates 126. Therefore, while the clamping block 120 is used to clamp and limit the detection device body 210 horizontally, the two sets of limit plates 126 on both sides can also be used to limit the detection device body 210 longitudinally, thereby ensuring the stability of the detection device body 210 after being connected to the base plate 110 and preventing the detection device body 210 from falling off.

[0027] Furthermore, a protective rubber pad is provided on one side surface of each clamping block 120 and the limiting plate 126 .

[0028] By providing a protective rubber pad, the friction between the clamping block 120 and the limiting plate 126 and the surface of the detection device body 210 is improved to improve the clamping stability and protect the surface of the detection device body 210 from being scratched, thereby improving the overall practicality during use.

[0029] See also Figure 2 One end of each winding post 130 is provided with an anti-slip plate 131 .

[0030] By providing an anti-drop plate 131 at the bottom of the winding post 130, it is possible to prevent the wire 220 from falling off from the bottom of the winding post 130 due to gravity after the wire 220 is wound thereon, thereby further improving stability during use.

[0031] Furthermore, a non-slip rubber pad is provided on one side surface of the anti-slip plate 131 .

[0032] When the mounting base 100 is placed as a whole on a plane, the winding pole 130 can be used as a leg to lift the whole. The anti-skid rubber pad provided on the surface of the anti-slip plate 131 can increase the friction between the whole and the plane to prevent the whole from slipping.

[0033] Furthermore, a plurality of limiting posts 151 evenly distributed in a straight line are fixedly connected between the outer wall of the handle 150 and the surface of one end of the bottom plate 110 .

[0034] The handle 150 can be convenient for the user to hold the whole body. When it is necessary to use a hook or other structure to hang the mounting base 100 as a whole on the user's body, the hook is located between the corresponding two limit columns 151. The two limit columns 151 limit the hook to prevent the hook from making a large displacement inside the entire handle 150 and causing the whole body to shake significantly, which can relatively improve the stability of the whole body when it is hung on the user's body.

[0035] Working principle: According to the specific size of the detection device body 210, the bidirectional threaded rod 112 is rotated to adjust the distance between the two clamping blocks 120, and the detection device body 210 is prevented from being between the two clamping blocks 120 and the bidirectional threaded rod 112 is continuously rotated so that the two clamping blocks 120 complete the clamping of the detection device body 210, and at the same time, the limit plates 126 at both ends of each clamping block 120 are pulled so that the surface of one side of each limit plate 126 is attached to the surface of the corresponding side of the detection device body 210, so as to further stabilize the clamping effect and the detection device body 210 is limited in both longitudinal and transverse directions to ensure the stability of the connection. When storage is required, several wires 220 can be wound around several corresponding winding poles 130 according to actual conditions, so as to avoid damage to the wires 220 during storage. After the wires 220 are wound and tightened, the detection probe 230 is engaged in the corresponding probe buckle 140 to limit the detection probe 230, so as to avoid the detection probe 230 lacking a limit and causing it to swing freely during storage, causing damage to the connection between it and the wire 220 or damage caused by collision.

[0036] It should be noted that the specific models and specifications of the detection device body 210, the wire 220 and the detection probe 230 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0037] The power supply and principles of the detection device body 210 , the wire 220 , and the detection probe 230 are clear to those skilled in the art and will not be described in detail herein.

[0038] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
