[0001] The utility model relates to the technical field of rail flaw detection in rail transit, and particularly to a fixing device for a rail weld flaw detector. Background Art

[0002] At present, when the railway industry conducts operations on rail weld flaw detectors, generally a handheld weld flaw detector is used to detect rail welds. During the detection process, the detection personnel need to adjust the detection probe used by the rail weld flaw detector and timely adjust the detection sensitivity according to different positions of the rail weld detection, so as to confirm the damage of the rail weld.

[0003] During actual operation, since the detection personnel need to hold the detection probe with one hand and continuously detect on the rail weld, and the other hand needs to continuously adjust the instrument, it is impossible to hold the instrument at the same time. Although the flaw detector can be placed on the sleeper and ballast during operation in a suitable environment, on the one hand, placing it on the sleeper will cause the instrument screen to be too far away from the detection personnel, and the visual distance cannot clearly and accurately judge the waveform; on the other hand, the detection personnel often need to move to adjust the flaw detection operation at different angles of the rail weld, which will also make it inconvenient to adjust the instrument parameters and add coupling liquid, and it is not convenient to accurately calibrate the damage of the rail weld; on the other hand, during the operation, the flaw detector is held by hand for a long time, the labor intensity of the detection personnel is large, and it is easy to cause physical fatigue and arm soreness, resulting in a decline in operation efficiency and operation quality.

[0004] Therefore, it is necessary to study a fixing device for a rail weld flaw detector to solve the above problems or alleviate the influence brought by the above problems. Summary of the Invention

Through the cooperation of the clamping mechanism and the mounting mechanism, the rail weld flaw detector can be installed and fixed by using the body trunk of the detection personnel.

[0029] The present utility model will be further described below in conjunction with the drawings.

[0030] As Figure 1 shown, the fixing device for the rail weld flaw detector of the present utility model may include:

[0031] The installation mechanism 1 is used to be fixedly worn on the tester;

[0032] The clamping mechanism 3 is used to fixedly clamp the rail weld flaw detector;

[0033] The adjusting mechanism 2 is connected between the installation mechanism 1 and the clamping mechanism 3. The adjusting mechanism 2 can adjust the position of the clamping mechanism 3 relative to the installation mechanism 1 so that the rail weld flaw detector is in a position convenient for the tester to operate and observe.

[0034] Specifically, the fixing device for the rail weld flaw detector of the present utility model fixedly clamps the rail weld flaw detector through the clamping mechanism 3 and is fixedly worn on the tester through the installation mechanism 1, that is, the body trunk of the tester can be used to install and fix the rail weld flaw detector. And the installation mechanism 1 and the clamping mechanism 3 are connected through the adjusting mechanism 2. The adjusting mechanism 2 can adjust the position of the clamping mechanism 3 relative to the installation mechanism 1, that is, can adjust the position of the rail weld flaw detector relative to the tester, so as to flexibly adjust the position of the rail weld flaw detector and make it always in a position convenient for the tester to operate and observe.

[0035] In this way, when detecting, there is no need to hold the rail weld flaw detector by hand, and the weight of the rail weld flaw detector can be transferred to the human core trunk, which can reduce the labor intensity of the tester and slow down the fatigue speed. At the same time, the rail weld flaw detector can always be kept in a suitable position relative to the tester, which is convenient for the tester to operate and observe, and can greatly improve the work efficiency and detection accuracy.

[0036] In one example, as Figure 1 and Figure 2 shown, the installation mechanism 1 includes a wearing component and a fixed support 13. The wearing component is fixedly connected to the fixed support 13, and the fixed support 13 is connected to the adjusting mechanism 2.

[0037] Specifically, the wearing component can be worn on the tester and in a fixed state, so that the fixed support 13 fixedly connected to it is also in a fixed state relative to the tester. The adjusting mechanism 2 is connected to the fixed support 13. The fixed support 13 can serve as the fixed support basis for the adjusting mechanism 2 and the clamping mechanism 3, so that the rail weld flaw detector installed on the clamping mechanism 3 can be in a fixed position relative to the tester. It should be noted that the connection between the adjusting mechanism 2 and the fixed support 13 is detachable, so that the installation mechanism 1 can be worn when it is in a disassembled state with the adjusting mechanism 2, and it is also convenient for storage and handling.

[0038] In one example, as Figure 1 and Figure 2As shown, the wearable assembly includes a first wearable member 11 and a second wearable member 12, and the first wearable member 11 and the second wearable member 12 are respectively fixedly connected to the upper end and the lower end of the fixed support member 13.

[0039] Specifically, when the wearable assembly is worn on the tester, the fixed support member 13 is located at the abdominal position of the tester. The first wearable member 11 is connected to the upper end of the fixed support member 13, and the first wearable member 11 is fixed around the chest, shoulders, and back of the tester; the second wearable member 12 is connected to the lower end of the fixed support member 13, and the second wearable member 12 is fixed around the waist of the tester. In this way, both the upper and lower ends of the fixed support member 13 are in relatively fixed positions, so that the overall position of the fixed support member 13 can be kept fixed.

[0040] Furthermore, the first wearable member 11 is of a vest-like structure, and the second wearable member 12 is of a belt-like structure. Both the first wearable member 11 and the second wearable member 12 are closely attached to the tester's body and are designed with reinforcement, and the load-bearing capacity can reach more than 20 kg. Both the first wearable member 11 and the second wearable member 12 can be adjusted in terms of stretching to be suitable for testers of different body sizes. Both the first wearable member 11 and the second wearable member 12 can be adjusted in terms of stretching by using snap fasteners.

[0041] Even further, the fixed support member 13 is of an inverted T-shaped structure, made of a rigid material, and has good stability.

[0042] In one example, as Figure 1 shown, the adjusting mechanism 2 includes at least two support connecting rods 21, and adjacent two support connecting rods 21 are connected by an adjusting component, and the adjusting component enables one of the support connecting rods 21 to swing up and down and left and right relative to the other support connecting rod 21.

[0043] Specifically, the adjusting mechanism 2 may include two connected support connecting rods 21, or multiple support connecting rods 21 connected in sequence, and the number of support connecting rods 21 can be set according to actual needs without specific limitation. Adjacent two support connecting rods 21 are connected by an adjusting component, and the adjusting component can enable one of the support connecting rods 21 to swing up and down and left and right relative to the other support connecting rod 21, so that the clamping mechanism 3 can be adjusted in terms of different distances, different heights, and multiple angles relative to the mounting mechanism 1.

[0044] In one example, as Figure 1 and Figure 3As shown, the adjustment assembly includes a first adjustment member 22 and two second adjustment members 23. The two second adjustment members 23 are hinged to both ends of the first adjustment member 22, and the second adjustment member 23 can rotate horizontally relative to the first adjustment member 22; the second adjustment member 23 is hinged to the end of the support connecting rod 21, and the support connecting rod 21 can rotate in the vertical plane relative to the second adjustment member 23.

[0045] Specifically, adjacent support connecting rods 21 are connected by an adjustment assembly. The adjacent ends of the two support connecting rods 21 are both hinged to the second adjustment member 23, and the two second adjustment members 23 are respectively hinged to both ends of the first adjustment member 22. The second adjustment member 23 is hinged to the first adjustment member 22, and the second adjustment member 23 can rotate horizontally relative to the first adjustment member 22, which enables the support connecting rod 21 to swing left and right, and can realize the adjustment of the horizontal position and side view angle of the rail weld detector. The second adjustment member 23 is hinged to the end of the support connecting rod 21, and the support connecting rod 21 can rotate in the vertical plane relative to the second adjustment member 23, which enables the support connecting rod 21 to swing up and down, and can realize the adjustment of the up and down position and pitch angle of the rail weld detector.

[0046] Further, the first adjustment member 22 is of I-shaped structure, and its left and right ends have horizontal grooves; the second adjustment member 23 has an arc-shaped convex portion, and the arc-shaped convex portion is rotatably connected in the horizontal groove of the first adjustment member 22.

[0047] Specifically, the first adjustment member 22 is of I-shaped structure, and horizontal grooves are formed at both its left and right ends. One end of the second adjustment member 23 connected to the first adjustment member 22 is in the shape of an arc-shaped convex portion, and the arc-shaped convex portion matches the horizontal groove, that is, the arc-shaped convex portion can be embedded between the two horizontal side walls of the horizontal groove and is connected by a pin shaft to achieve mutual hinge, so that the second adjustment member 23 can rotate horizontally relative to the first adjustment member 22.

[0048] Further, a vertical groove is formed at one end of the second adjustment member 23 connected to the support connecting rod 21. The end of the support connecting rod 21 is clamped between the two vertical side walls and is connected by a pin shaft to achieve mutual hinge, so that the support connecting rod 21 can rotate in the vertical plane relative to the second adjustment member 23.

[0049] It should be noted that the adjustment of the adjustment assembly and the support connecting rod 21 can be manually adjusted or can be automatically controlled and adjusted in cooperation with a motor drive. The support connecting rod 21 and the mounting mechanism 1 or the clamping mechanism 3 can be connected in the form of an adjustment assembly, or can be connected by other fixed connection methods or detachable connection methods, and can be specifically set according to the actual situation.

[0050] In one example, such as Figure 1 and Figure 3As shown, the support connecting rod 21 has a hollow portion extending axially therethrough, and an elastic member 24 is disposed in the hollow portion along its axial direction. The two ends of the elastic member 24 are respectively connected to the second adjusting member 23.

[0051] Specifically, since the inspector needs to hold the probe and move it to adjust the detection position during operation, the body will inevitably shake. The frequent shaking of the body will cause the screen of the rail weld flaw detector on the clamping mechanism 3 to shake, resulting in blurred vision of the inspector and a decline in the operation quality. After installing the elastic member 24 in the hollow portion of each support connecting rod 21, the shaking amplitude can be reduced, playing a role in compression resistance and shock absorption, so as to better assist the detection operation. The elastic member 24 can be a spring. It should be noted that when the end of the support connecting rod 21 is not connected to the second adjusting member 23, the elastic member 24 is connected to other structures corresponding to the end of the support connecting rod 21.

[0052] In one example, the adjusting mechanism 2 can be a six-axis robotic arm to adjust the clamping mechanism 3.

[0053] In one example, as Figure 1 shown, the clamping mechanism 3 includes a fixed jaw 31, a movable jaw 32, and a moving adjustment rod 33. The fixed jaw 31 is fixedly connected to the adjusting mechanism 2. One end of the moving adjustment rod 33 is fixedly connected to the fixed jaw 31, and the movable jaw 32 is movably connected to the other end of the moving adjustment rod 33, and the movable jaw 32 can move along the axial direction of the moving adjustment rod 33 and cooperate with the fixed jaw 31 to fixedly clamp the rail weld flaw detector.

[0054] Specifically, the moving adjustment rod 33 is erected vertically. The fixed jaw 31 is used to clamp the lower end of the rail weld flaw detector, and the movable jaw 32 moves vertically along the axial direction of the moving adjustment rod 33 and clamps the upper end of the rail weld flaw detector to stably clamp the rail weld flaw detector from the upper and lower ends.

[0055] Furthermore, a spring (not shown in the drawings) is provided between the movable jaw 32 and the fixed jaw 31 along the axial direction of the moving adjustment rod 33. The spring has a pre-tightening force that brings the movable jaw 32 closer to the fixed jaw 31, so that the movable jaw 32 and the fixed jaw 31 can stably clamp the rail weld flaw detector.

[0056] It should be noted that the front of the rail weld flaw detector clamped by the clamping mechanism 3 faces the inspector for the convenience of the inspector's operation and observation.

[0057] In one example, as Figure 1As shown, a locking member 34 is provided on the movable jaw 32, and the locking member 34 is used to lock the movable jaw 32 and the moving adjustment rod 33. That is, the locking member 34 locks the movable jaw 32 relative to the fixed jaw 31, preventing the rail weld flaw detector from accidentally moving out between the movable jaw 32 and the fixed jaw 31 under the action of external force and causing damage, which can improve the safety performance of the fixing device.

[0058] To better understand the above embodiments, the following further describes the use process of the fixing device of the present invention for fixing a rail weld flaw detector in combination with the accompanying drawings for detection operations.

[0059] Wear the installation mechanism 1 on the tester and adjust the buckle to ensure firm fixation; connect the adjustment mechanism 2 to the fixed support 13 of the installation mechanism 1 to transfer the weight to the core torso of the human body; place the rail weld flaw detector for operation on the clamping mechanism 3 and lock it through the locking member 34 to make it firmly clamped; according to the needs of the flaw detection operation, adjust the angle, direction and distance of the rail weld flaw detector facing the operator through the adjustment mechanism 2 to facilitate the operator's operation and observation of the screen; normally carry out the rail weld flaw detection operation. After the operation is completed, first remove the rail weld flaw detector, then remove the adjustment mechanism 2 from the installation mechanism 1, and finally remove the installation mechanism 1 from the tester.
