Description

Technical Field

[0001] This invention relates to the field of rail transit, and in particular to a device and method for controlling the inner dimensions of a traction beam. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] After the traction beam and coupler mounting brackets are assembled, they are connected by welding. The cooling and shrinkage of the weld will cause dimensional changes in the traction beam, such as the diagonal difference and the inner width.

[0004] Currently, to control changes in the dimensions of the traction beam, the beam dimensions are fixed by pre-welding process supports before the formal welding of the welds. See details below. Figure 1 As shown, the process beam 17 is welded above the two traction beams to control the dimensional changes of the traction beams. Weld points 18 are formed between the process beam and the traction beam. The inventors have found that this method has the following problems:

[0005] 1) The process beam needs to be connected to the base material by welding. After the process beam is used, it also needs to be cut. Both the process beam and the traction beam need to be ground, which is time-consuming and labor-intensive.

[0006] 2) The process beams need to be replaced after several cutting and grinding processes, resulting in low utilization.

[0007] 3) The length of the process beam is fixed and cannot be adjusted, limiting its applicability. Summary of the Invention

[0008] In view of the shortcomings of the existing technology, the first objective of the present invention is to provide a traction beam inner section size control device that can adjust the length and width directions as a whole, and is easy to install and disassemble.

[0009] The second objective of this invention is to provide a method for operating a traction beam inner section size control device, wherein the positioning component is always perpendicular to the traction beam, the engaging component is fully engaged with the traction beam, and the welding deformation of the traction beam is effectively controlled.

[0010] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0011] A traction beam inner dimension control device includes a T-shaped positioning member, with its two opposite ends abutting against the inner surface of the traction beam. The other end of the positioning member is connected to one end of a length adjuster, and the other end of the length adjuster is connected to a T-shaped engaging assembly. At least one end of the engaging assembly engages with the traction beam. At least one of the opposite sides of the engaging assembly is provided with a width adjuster. The length of the control fixture is adjusted by the length adjuster, and the width of the control fixture is adjusted by the width adjuster.

[0012] As described above, the inner dimension control device for a traction beam includes a locking assembly comprising a T-shaped connecting rod. Width adjusters are provided on both opposite sides of the connecting rod. The width adjusters are connected to a locking component, which engages with the traction beam and the upper plane of the traction beam, ensuring the stability of the control fixture setup.

[0013] As described above, in a traction beam inner gauge size control device, the width adjuster is connected to the clamping member via a connector.

[0014] As described above, in a traction beam inner gauge size control device, the connecting member is a ball-head connector. The ball-head connector facilitates the connection between the clamping member and the width connector, making the connection tight and not easy to loosen.

[0015] As described above, in a traction beam inner gauge size control device, a frustum-shaped connecting block is provided between the connecting member and the clamping member, and the side of the connecting block with a larger diameter is connected to the clamping member.

[0016] Considering that the clamping component needs to engage with the traction beam, one side of the clamping component is fixedly connected to the side of the connecting block, and the other side of the clamping component is connected to the upper side of the connecting block.

[0017] As described above, in a traction beam inner section size control device, the clamping member is a gate-type clamping member, and the width of the clamping member is adapted to the width of the traction beam.

[0018] As described above, the inner dimension control device for a traction beam includes a length adjuster comprising a first cylinder, with a first screw and a second screw rotatably mounted at both ends of the first cylinder, the first screw being connected to the positioning member and the second screw being connected to the engaging assembly.

[0019] As described above, in a traction beam inner gauge size control device, at least one first grip is provided on the outer side of the first cylinder, which facilitates the adjustment of the length adjuster.

[0020] As described above, a traction beam inner gauge size control device includes a width adjuster comprising a second cylinder, with a third screw and a fourth screw rotatably mounted at both ends of the second cylinder, the third screw being connected to one end of the connecting rod, and the fourth screw being connected to the clamping member;

[0021] At least one second grip is provided on the outer side of the second cylinder, which facilitates the adjustment of the width adjuster.

[0022] Secondly, the present invention also provides a method for operating a traction beam inner section size control device, comprising the following:

[0023] After the traction beam and coupler mounting base are assembled and tack welded, measure the length of the traction beam at the position where it needs to be fixed.

[0024] Based on the measured length of the traction beam that needs to be fixed, adjust the length adjuster so that the length of the tooling controlling the inner dimension of the traction beam reaches the appropriate position.

[0025] Place the inner dimension control fixture of the traction beam at the front end of the traction beam, and make the two ends of the positioning part in opposite directions abut against the inner side of the traction beam respectively. Adjust the width adjuster to make the engaging component engage with the traction beam.

[0026] When removing the inner section size control fixture of the traction beam, simply adjust the width adjuster to remove the inner section size control fixture from the traction beam.

[0027] The beneficial effects of the present invention are as follows:

[0028] 1) This invention provides control tooling with a reasonable overall structure. The two ends of the positioning parts can abut against the inner side of the traction beam, and the engaging components can engage with the traction beam to effectively ensure the stability of the control tooling. It does not require welding to the traction beam and is easy to install and dismantle. The overall structure can be stably set relative to the traction beam, thereby effectively controlling the welding deformation generated during the welding process of the traction beam and playing a role in preventing deformation of the traction beam. The tooling is easy to use, and the whole is detachable and has a high reusability.

[0029] 2) The control fixture of this invention uses a length adjuster and a width adjuster. The length adjuster can adjust the length of the control fixture to meet the fixed position length of the traction beam, and the width adjuster can meet the width requirement between the two traction beams. It has a wide range of applications. The adjustable settings of the two also make it convenient to remove or install the control fixture from the inner part of the traction beam.

[0030] 3) In this invention, the two ends of the positioning component abut against the inner side of the traction beam, which is a reasonable arrangement; and the clamping component is a gate-shaped component that can effectively engage with the upper plane of the traction beam. The two components work together to ensure the stability of the control fixture.

[0031] 4) In this invention, ball-head connectors are provided on opposite sides of the connecting rod. Since the width adjuster adjusts the width of the tooling by rotation, rotating the ball-head connector after adjustment ensures that the clamping part is always perpendicular to the upper plane of the traction beam. Moreover, the ball-head connector facilitates the connection between the clamping part and the width connector, making the connection tight and not easy to loosen.

[0032] 5) The method for controlling the working of the tooling in this invention ensures that the positioning part is always perpendicular to the inner side of the traction beam, the engaging component is fully engaged with the traction beam, and the overall welding deformation of the traction beam is effectively controlled; at the same time, the entire structure does not require welding, making it convenient for installation and dismantling.

[0043] As described in the background section, the existing technology for controlling deformation during traction beam welding is time-consuming and labor-intensive. In order to solve the above-mentioned technical problems, this invention proposes a device and working method for controlling the inner dimension of a traction beam.

[0044] Example 1

[0045] In a typical embodiment of the present invention, reference is made to Figure 2 and Figure 3 As shown, a traction beam inner dimension control device includes a T-shaped positioning member. The two ends of the positioning member in opposite directions abut against the inner surface of the traction beam. The other end of the positioning member is connected to one end of a length adjuster. The other end of the length adjuster is connected to a T-shaped engaging assembly. At least one end of the engaging assembly engages with the traction beam 14. At least one side of the two opposite sides of the engaging assembly is provided with a width adjuster. The length of the control fixture is adjusted by the length adjuster, and the width of the control fixture is adjusted by the width adjuster.

[0046] Specifically, the positioning element is a positioning rod 1. The two circular ends of the positioning rod 2 are used to abut against the inner side of the traction beam 14. The longer side of the positioning rod 1 is perpendicular to the inner side of the traction beam 14, and the shorter side of the positioning rod 1 is connected to the length adjuster.

[0047] In this embodiment, the engaging assembly includes a T-shaped connecting rod 4. Width adjusters are provided on both opposite sides of the connecting rod 4. The width adjusters are connected to the clamping parts. The clamping parts on both sides, namely the first clamping part 8 and the second clamping part 12, respectively engage with the traction beam 14 on the corresponding side. The clamping parts engage with the upper plane of the traction beam to ensure the stability of the control fixture.

[0048] In this embodiment, the width adjuster is connected to the clamping member through a connector. Specifically, the width adjuster is a first width adjuster 6 and a second width adjuster 10. Specifically, the connector is a ball joint connector, which is a common ball joint connector. Specifically, it is a first ball joint connector 7 and a second ball joint connector 11. Because the width adjuster adjusts the width of the tooling by rotation, rotating the ball joint connector after adjustment ensures that the clamping member is always perpendicular to the upper plane of the traction beam, ensuring that the clamping member can still effectively engage with the traction beam after the width of the tooling is adjusted. Moreover, the ball joint connector facilitates the connection of the clamping member with the corresponding width connector, and the ball joint connector ensures that the connection is tight and not easy to loosen.

[0049] In addition, a frustum-shaped connecting block is provided between the connector and the clamping member. Taking one side as an example, a first connecting block 9 is provided between the first ball connector 7 and the first clamping member 8. The side of the first connecting block 9 with a larger diameter is connected to the first clamping member 8, and the side of the first connecting block with a smaller diameter is connected to the first ball connector 7.

[0050] Among them, the clamping component is a gate-shaped clamping component, which is equivalent to the clamping component having a groove on the side facing the traction beam. The groove engages with the upper plane of the traction beam 14. After the first clamping component 8 and the second clamping component 12 engage with the traction beam 14, the central axis of the tooling width adjuster is perpendicular to the upper plane of the traction beam. It can be understood that the width of the clamping component, especially the width of the groove, is adapted to the width of the traction beam 14. Considering that the clamping component needs to engage with the traction beam, one side of the clamping component is fixedly connected to the side of the connecting block, and one side of the clamping component is connected to the upper side of the connecting block.

[0051] Understandably, the length adjuster includes a first cylinder 2, which is a circular hollow cylinder with a set length. The first cylinder 2 has a first screw 13 and a second screw 3 that are rotatably mounted at both ends. The first screw 13 and the second screw 2 are respectively mounted through the ends of the first cylinder 2 via threaded structures. The first screw 13 and the second screw 2 are both located in the direction of the central axis of the first cylinder. The first screw 13 is connected to the shorter side of the positioning rod 1, and the second screw 3 is connected to the longer side of the connecting rod 4 of the engaging assembly.

[0052] In this embodiment, at least one first grip is provided on the outer side of the first cylinder 2. The first grip is provided on both the upper and lower sides of the first cylinder, and the first grip facilitates the adjustment of the length adjuster.

[0053] In addition, regarding the width adjuster, the width adjuster includes a second cylinder with a set length. The two ends of the second cylinder are respectively rotatably provided with a third screw 5 and a fourth screw 15. The third screw 5 and the fourth screw 15 are provided through the ends of the second cylinder by a threaded structure. The third screw 5 and the fourth screw 15 are located in the direction of the central axis of the second cylinder. The third screw 5 is connected to one end of the connecting rod 4, and the fourth screw 15 is connected to the clamping member. At least one second grip is provided on the outside of the second cylinder. In this embodiment, the second grip is provided on both the upper and lower sides of the second cylinder. The provision of the second grip facilitates the adjustment of the width adjuster.

[0054] Specifically, both the first grip and the second grip are round rods 16 for easy operation. The round rods 16 have a set length, and the length of the round rod of the first grip can be longer than the length of the round rod of the second grip.

[0055] The control fixture provided in this embodiment has a reasonable overall structure. The two ends of the positioning component can abut against the inner side of the traction beam, and the engaging component can engage with the traction beam to effectively ensure the stability of the control fixture. It does not require welding to the traction beam and is easy to install and remove. The overall structure can be stably set relative to the traction beam, thereby effectively controlling the welding deformation generated during the welding process of the traction beam and playing a role in preventing deformation of the traction beam. The fixture is easy to use, and the whole is detachable and has a high reusability.

[0056] Example 2

[0057] This embodiment provides a method for operating a traction beam inner section size control device, including the following:

[0058] After the traction beam and coupler mounting base are assembled and tack welded, measure the length of the traction beam at the position where it needs to be fixed.

[0059] Based on the measured length of the traction beam that needs to be fixed, adjust the first screw 13 and / or the second screw 3 of the length adjuster so that the length of the traction beam inner dimension control fixture reaches the appropriate position.

[0060] Place the inner dimension control fixture of the traction beam at the front end of the traction beam. The two ends of the positioning rod 1 in opposite directions abut against the inner side of the traction beam 14. Adjust the first width adjuster 6 and / or the second width adjuster 10 so that the first clamping member 8 and the second clamping member 12 are engaged with the traction beam 14 on the corresponding side.

[0061] When removing the inner section size control fixture of the traction beam, simply adjust the first width adjuster 6 and / or the second width adjuster 10 to remove the inner section size control fixture of the traction beam.

[0062] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
