Description

Technical Field

[0001] The present invention relates to the technical field of angle detection devices, and in particular to a detection device and a detection method. Background Art

[0002] With the rapid development of my country's infrastructure construction capabilities, in order to meet the requirements of railway bridge erection, there are now three-car special trains in one structure, with DL1 large-tonnage prefabricated beam transportation special vehicles at both ends and DNX17K flat car-container dual-purpose flat car in the middle. DL1 type vehicles are mainly used to transport prefabricated beams with a span of 32m and a dead weight of less than 148t. DL1 type large-tonnage prefabricated beam special trains have entered the time specified in the factory maintenance schedule according to the railway freight car regular inspection requirements. Some railway freight car maintenance factories are carrying out maintenance work on this type of vehicle. The bridge support device installed on the car body is the main connection and bearing structure for supporting the prefabricated beam. The maintenance and assembly quality of the bridge support device directly determines the performance of the train and the safety of vehicle operation. When the vehicle is under repair, it is required to check the rotation angle of the bridge support device. The "Technical Conditions for Inspection and Maintenance of Special Hook Buffer Stoppers and Support Devices for DL1 Type Large-tonnage Precast Beam Transport Special Vehicle" stipulates: "When the bridge support is erected and in the working position, its effective angle along the lateral direction of the vehicle is required to be 58°~62°". That is, when the bridge support device is in the working position, the effective angle with the lateral direction of the vehicle should be 58°~62°. However, the single-sided (one side or the other side of the vehicle) bridge support device is a spatial structure composed of two obliquely installed support rods. It is difficult for a general angle ruler to effectively detect the angle with the lateral direction. Summary of the invention

[0003] The present invention aims to solve the problem that a common angle ruler is difficult to effectively detect the angle between a support rod in a bridge support device and a transverse direction.

[0004] In order to solve the above problems, the present invention provides a detection device for detecting the angle between the support rod of a special vehicle group for transporting prefabricated beams and the lateral direction of the vehicle group, comprising a base, a fixed scale, a movable bracket and a detection rod-touching frame, the fixed scale is provided with a guide structure, one end of the movable bracket is hinged to the base, the other end of the movable bracket is suitable for rotating along the guide structure, one end of the detection rod-touching frame is connected to the movable bracket, the other end of the detection rod-touching frame is suitable for abutting against the support rod, and the guide structure is suitable for limiting the rotation of the movable bracket within a preset angle range.

[0005] Compared with the prior art, the detection device provided by the present invention has but is not limited to the following beneficial effects:

[0006] When the lateral direction (left and right direction, the front direction is the forward or backward direction of the special vehicle set) of the support rod and the special vehicle set is specified to be 58°~62°, that is, when the bridge support device (including two support rods) is in the working position and the effective angle with the lateral direction of the special vehicle set should be 58°~62°, the guide structure limits the rotation of the movable bracket within the preset angle range, and the preset angle range is the corresponding 58°~62°, that is, the minimum angle between the movable bracket and the horizontal direction can be the corresponding 58°, and the maximum angle between the movable bracket and the horizontal direction can be the corresponding 62°. When detecting whether the lateral angle between the support rod and the special vehicle set meets the specification requirements, the detection device can be placed on the prefabricated beam bearing platform first, and then the movable bracket can be rotated to the minimum angle of 58°, and then the detection device can be moved laterally and moved toward the swivel seat at the bottom of the support rod; when the base of the detection device contacts the swivel seat at the bottom of the support rod, the detection rod frame and the support rod are also in contact at the same time, indicating that the support rod is transversely aligned with the special vehicle set. The angle between them is exactly 58°, and the assembly quality of the bridge support rod is qualified; when the base of the detection device contacts the rotating seat, the detection rod frame contacts the support rod, which means that the angle between the support rod and the special vehicle group in the horizontal direction is less than 58°, and the assembly quality of the bridge support rod is unqualified; when the base of the detection device contacts the rotating seat, the detection rod frame does not contact the support rod, which means that the angle between the support rod and the special vehicle group in the horizontal direction is greater than 58, and then, the movable bracket is rotated to the maximum angle of 62°, that is, the movable bracket is rotated from the horizontal angle of 58° to the position with an angle of 62° with the horizontal direction. Before reaching the maximum angle of 62°, if the detection rod frame contacts the support rod, it means that the angle between the support rod and the special vehicle group in the horizontal direction is greater than 58° and less than 62°, and the assembly quality of the bridge support rod is qualified. After the movable bracket reaches the maximum angle of 62°, the detection rod frame still does not contact the support rod, which means that the angle between the support rod and the special vehicle group in the horizontal direction is greater than 62°, and the assembly quality of the bridge support rod is unqualified.

[0007] Furthermore, when the movable bracket 3 rotates to one end of the guide structure, the angle between the movable bracket 3 and the horizontal direction is a minimum angle of 28°; when the movable bracket 3 rotates to the other end of the guide structure, the angle between the movable bracket 3 and the horizontal direction is a maximum angle of 62°.

[0015] When the base 1 is in contact with the rotating base, the movable bracket 3 is rotated along the guide structure of the detection device to the maximum angle of the preset angle range;

[0016] After the base 1 contacts the rotating seat and before the movable bracket 3 rotates to the maximum angle, the detection rod holder 4 contacts the support rod 5, and the included angle between the support rod 5 and the special vehicle group 8 in the transverse direction is within the preset angle range;

[0017] When the base 1 contacts the rotating seat, the detection touch rod frame 4 at the minimum angle contacts the support rod 5, and the included angle between the support rod 5 and the special vehicle group 8 in the horizontal direction meets the effective angle range;

[0018] When the movable bracket 3 rotates to the maximum angle, the detection rod bracket 4 contacts the support rod 5, and the angle between the support rod 5 and the special vehicle group 8 in the transverse direction meets the effective angle range.

[0037] With the rapid development of my country's infrastructure construction capacity, in order to meet the requirements of railway bridge erection, see Figure 3 and Figure 4The existing three-car structure special vehicle set has DL1 large-tonnage precast beam transport special vehicles at both ends and DNX17K flat car-container dual-purpose flat car in the middle. DL1 vehicles are mainly used to transport precast beams with a span of 32m and a deadweight of less than 148t. The DL1 large-tonnage precast beam special vehicle set has entered the time specified in the factory maintenance schedule in accordance with the railway freight car regular inspection requirements. Some railway freight car maintenance factories are carrying out maintenance work on this vehicle type. The bridge support device installed on the vehicle body is the main connection and bearing structure supporting the precast beam. The bridge support device includes a precast beam bearing platform 6 and a bridge support placed flat on the vehicle body. Among them, the precast beam 7 is placed on the precast beam bearing platform 6, and the bridge support is distributed on both sides of the precast beam bearing platform 6. The maintenance and assembly quality of the bridge support directly determines the performance of the vehicle set and the safety of vehicle operation. When the vehicle is under repair, it is required to check the rotation angle of the bridge support device. The "Technical Conditions for Inspection and Maintenance of Special Hook Buffer Stoppers and Support Devices for DL1 Type Large-tonnage Precast Beam Transport Special Vehicle" stipulates: "When the bridge support is erected and in the working position, the minimum effective angle along the lateral direction of the vehicle is required to be 58°~62°". That is, when the bridge support is in the working position, the effective angle with the lateral direction of the vehicle should be 58°~62°. However, the single-sided (one side or the other side of the vehicle) bridge support is a spatial structure composed of two obliquely installed support rods 5. It is difficult for a general angle ruler to effectively detect the angle with the lateral direction (left and right direction). The bottom end of the support rod 5 is hinged to the precast beam bearing platform 6 through a swivel seat, and the other end is connected to the supporting precast beam 7.

[0038] Based on the above problem that the angle of the support rod is difficult to detect, see Figures 1 to 4 A detection device according to an embodiment of the present invention is used to detect the angle between the support rod 5 of a special vehicle group for transporting precast beams and the special vehicle group 8 in the lateral direction, and includes a base 1, a fixed scale 2, a movable bracket 3 and a detection rod-touching frame 4. The fixed scale 2 is provided with a guide structure, one end (bottom end) of the movable bracket 3 is hinged to the base 1, and the other end of the movable bracket 3 is suitable for rotating along the guide structure, one end of the detection rod-touching frame 4 is connected to the movable bracket 3, and the other end of the detection rod-touching frame 4 is suitable for abutting against the support rod 5, and the guide structure is suitable for limiting the rotation of the movable bracket within a preset angle range.

[0039] In this embodiment, when the movable bracket 3 is rotated to one end of the guide structure, the angle between the movable bracket 3 and the horizontal direction is the minimum angle, and when the movable bracket 3 is rotated to the other end of the guide structure, the angle between the movable bracket 3 and the horizontal direction is the maximum angle. If the effective angle range between the support rod 5 and the special vehicle group 8 in the lateral direction (left and right directions, the front direction is the forward or backward direction of the special vehicle group 8) is specified to be 58°~62°, that is, when the bridge support device (including two support rods 5) is in the working position and the effective angle between the special vehicle group 8 in the lateral direction should be 58°~62°, the guide structure limits the rotation of the movable bracket 3 within the preset angle range, and the preset angle range is the corresponding 58°~62°, that is, the minimum angle between the movable bracket 3 and the horizontal direction can be the corresponding 58°, and the angle between the movable bracket 3 and the horizontal direction is The maximum angle can be the corresponding 62°. When detecting whether the lateral angle between the support rod 5 and the special vehicle group 8 meets the specification requirements, the detection device can be placed on the prefabricated beam bearing platform 6 first, and then the movable bracket 3 is rotated to one end of the guide structure (the minimum angle between the movable bracket 3 and the horizontal direction), that is, at this time the angle between the movable bracket 3 and the horizontal direction is 58°, and then the detection device is moved laterally and moved toward the rotating seat at the bottom of the support rod 5; when the base 1 of the detection device is in contact with the rotating seat, the detection rod frame 4 is also in contact with the support rod 5 at the same time, indicating that the support rod 5 is in contact with the special vehicle group 8. The lateral angle between the dedicated vehicle group 8 is exactly 58°, and the assembly quality of the bridge support rod is qualified; before the base 1 of the detection device contacts the rotating seat, the detection rod frame 4 contacts the support rod 5, indicating that the lateral angle between the support rod 5 and the dedicated vehicle group 8 is less than 58°, and the assembly quality of the bridge support rod is unqualified; when the base 1 of the detection device contacts the rotating seat, the detection rod frame 4 does not contact the support rod 5, indicating that the lateral angle between the support rod 5 and the dedicated vehicle group 8 is greater than 58, and then, the movable bracket 3 is moved toward the other end of the guide structure (the minimum angle β between the movable bracket 3 and the horizontal direction) The movable bracket 3 is rotated from a horizontal angle of 58° to a horizontal angle of 62°. Before reaching the maximum angle of 62°, if the detection rod-touching frame 4 is in contact with the support rod 5, it means that the angle between the support rod 5 and the special vehicle group 8 in the lateral direction is greater than 58° and less than 62°, and the assembly quality of the bridge support rod 5 is qualified. After the movable bracket 3 reaches the maximum angle of 62°, the detection rod-touching frame 4 still does not contact the support rod 5, it means that the angle between the support rod 5 and the special vehicle group 8 in the lateral direction is greater than 62°, and the assembly quality of the bridge support rod 5 is unqualified.

[0040] Optionally, as mentioned above, the minimum angle may be 58° and the maximum angle may be 62°.

[0041] It can be understood that if the effective angle range of the support rod 5 and the special vehicle group 8 in the lateral direction (left and right direction, the front direction is the forward or backward direction of the special vehicle group 8) is specified to be between 63° and 66°, then the minimum angle of the preset angle range is the corresponding 63°, and the maximum angle is the corresponding 66°, and the detection principle is the same as above.

[0044] Here, the connecting rod 41 and the touch rod 42 form a T-shaped detection touch rod frame 4, so that the two support rods 5 in the bridge support can be detected simultaneously through the touch rod 42 parallel to the front and rear direction of the special vehicle group 8, which is more efficient.

[0045] See also Figure 2 Optionally, two fixed scales 2 are provided, and the two fixed scales 2 are spaced apart and arranged in parallel on the base 1. The movable bracket 3 includes an intermediate rod 31 and two rocker arms 32. One end of the rocker arm 32 is hinged to the base 1. The two rocker arms 32 are connected through the intermediate rod 31. The rocker arm 32 is suitable for rotating between the two ends of the slide groove 211.

[0046] Here, two fixed scales 2 and two rocker rods 32 that are spaced apart and arranged in parallel can ensure the structural stability of the detection device, ensure that the movable bracket 3 moves smoothly when rotating in the slide groove 211, and avoid detection errors.

[0047] See also Figure 1 Optionally, a first hinged support 11 is fixed on the base 1, and the swing rod 32 is rotatably connected to the first hinged support 11 via a first rotating shaft 321.

[0050] Here, in addition to being able to be directly inserted into the slide groove 211 to rotate between the two ends of the slide groove 211, the swing rod 32 can also be provided with a sliding rod 322, which is slidably connected in the slide groove 211 to indirectly achieve the limitation of the range of movement of the swing rod 32, that is, when the sliding rod 322 moves to one end of the slide groove 211, the angle between the swing rod 32 and the horizontal direction is the minimum angle, and when the sliding rod 322 moves to the other end of the slide groove 211, the angle between the swing rod 32 and the horizontal direction is the maximum angle.

[0051] See also Figure 1 Optionally, the fixed scale 2 includes a straight segment 22 and an arc segment 21, the bottom end of the straight segment 22 is vertically connected to the base 1, one end of the arc segment 21 is connected to the top of the straight segment 22, the slide groove 211 is opened on the arc segment 21 and extends along the arc direction of the arc segment 21, and the center of the arc segment 21 is consistent with the hinge point of the rocker arm 32.

[0052] Here, by setting the arc segment 21, and the center of the arc segment 21 is consistent with the hinge point of the pendulum 32, that is, the center of the arc segment 21 is located on the axis of the first rotating shaft 321, so that the pendulum 32 can be adjusted between 58° and 62° without swinging greatly, preventing the fixed scale 2 from being too high. At the same time, by setting the straight line segment 22, it is avoided that all the arc segments 21 occupy a long horizontal distance.

[0053] In addition, through the arrangement of the arc segment 21 , the slide groove 211 is an arc groove, which better matches the rotation of the swing rod 32 .

[0054] Optionally, the straight line segment 22 and the arc segment 21 are an integrated structure.

[0056] Optionally, the sliding rod 322 is a round rod, and both ends of the sliding groove 211 are concave surfaces that match the round rod.

[0057] In this way, the round rod is easy to process, and both ends of the slide groove 211 are concave surfaces that match the round rod, so that the slide rod 322 has a larger force-bearing area when sliding to the end of the slide groove 211.
