Description

Technical Field

The manufacturing tolerance of the existing technology cannot meet the above complex precision requirements, resulting in high error rate and low efficiency. Often, multiple reworks are required to meet the manufacturing requirements.

The top steel plate is welded to the middle steel plate, the longitudinal rib steel plate, the first end steel plate, and the second end steel plate. The bolt guide tubes are coaxial with the corresponding positioning holes.

[0043] In the process of constructing steel shear keys, in order to ensure that precision requirements are met and to improve manufacturing efficiency, such as... Figures 1-6 As shown, this invention provides a method for manufacturing steel shear keys. The method for manufacturing steel shear keys includes the following steps:

[0044] S1. Make a positioning device 1 for positioning the shear key base plate 2;

[0045] S2. Cut the shear key base plate 2 and open multiple positioning holes 21 on the shear key base plate 2 to process the reinforcing ring 22.

[0046] S3. Assemble and weld the reinforcing ring 22 to the shear key base plate 2. Multiple reinforcing rings 22 are set one-to-one with multiple positioning holes 21, and the corresponding reinforcing rings 22 and positioning holes 21 are arranged coaxially.

[0047] S4. The shear key base plate 2 is mounted on the positioning device 1 through the positioning hole 21 and the reinforcing ring 22.

[0048] S5. Weld the middle steel plate 3 perpendicularly to the extension direction of the shear key base plate 2 at the middle part of the shear key base plate 2.

[0049] S6. Weld the first end steel plate 4 vertically to the left side of the shear key base plate 2. The first end steel plate 4 is perpendicular to the middle steel plate 3.

[0050] S7. Multiple longitudinal rib steel plates 5 are welded perpendicularly at intervals on opposite sides of the middle steel plate 3 along the extension direction of the middle steel plate 3. The multiple longitudinal rib steel plates 5 are welded perpendicularly to the shear key bottom plate 2. Adjacent longitudinal rib steel plates 5 and the middle steel plate 3 form a compartment, and each compartment corresponds to a reinforcing ring 22.

[0051] S8. Weld the second end steel plate 7 vertically to the right side of the shear key base plate 2. The second end steel plate 7 is welded perpendicularly to the middle steel plate 3.

[0052] S9. Weld multiple bolt guide tubes 62 onto the top steel plate 6, with the side of the top steel plate 6 having the bolt guide tubes 62 facing the shear key base plate 2. The top steel plate 6 is welded to the middle steel plate 3, the longitudinal rib steel plate 5, the first end steel plate 4, and the second end steel plate 7. The bolt guide tubes 62 are coaxial with the corresponding positioning holes 21.

[0053] The above methods can effectively ensure the smooth progress of the steel shear key construction process, and also ensure that the positioning hole 21, the reinforcing ring 22 and the bolt guide tube 62 are set on the same axis, thus ensuring that the accuracy requirements are met, avoiding rework and improving manufacturing efficiency.

[0054] In some embodiments, step S1, the manufacturing of the positioning device 1 includes the following steps:

[0055] S11. Mark the installation positions of multiple positioning pins 12 on the positioning base plate 11; specifically, mark circles with crosshairs at the installation positions. The allowable tolerance for the position of the center of the circle from the center of the positioning base plate 11 is ±0.5mm. In this embodiment, two rows and six columns of circles are marked on the positioning base plate 11.

[0056] S12. Weld multiple locating pins 12 vertically to the corresponding installation positions. After welding, the allowable tolerance for the position of the end center of the locating pin 12 away from the center of the locating base plate 11 is ±0.5mm, and the verticality deviation of the locating pin 12 is less than 0.8mm. Manufacturing the positioning device 1 in this manner facilitates the subsequent positioning of the steel shear key, thereby ensuring smooth construction.

[0057] In some embodiments, in step S2, a welding bevel is formed at one end of the reinforcing ring 22. By setting the welding bevel, it is easier to weld the reinforcing ring 22 to the shear key base plate 2, and the welding strength can be guaranteed.

[0058] In some embodiments, in step S3, the concentricity deviation between the corresponding reinforcing ring 22 and the positioning hole 21 is no greater than 0.3 mm. This limitation ensures the welding accuracy of the reinforcing ring 22, facilitating its accurate placement on the positioning pin 12 and subsequent construction. Similarly, in this embodiment, two rows of six columns of positioning holes 21 are formed on the shear key base plate 2.

[0059] In some embodiments, after the shear key base plate 2 is installed on the positioning device 1 in step S4, the shear key base plate 2 remains horizontal. By ensuring that the shear key base plate 2 is horizontal, it is easier to ensure that it remains vertical during the subsequent welding of the middle steel plate 3, the first end steel plate 4, and the second end steel plate 7.

[0060] In some embodiments, step S7 further includes providing a horizontally oriented transverse rib steel plate 8 in each compartment. The transverse rib steel plate 8 is welded to the longitudinal rib steel plate 5 and the middle steel plate 3. A through hole 81 coaxial with the positioning hole 21 is formed on the transverse rib steel plate 8. By welding the transverse rib steel plate 8 to the longitudinal rib steel plate 5 and the middle steel plate 3, the strength of the steel shear key can be further improved. Moreover, by setting the through hole 81 on the transverse rib steel plate 8 coaxial with the positioning hole 21, it is convenient for the connecting bolts to pass through smoothly during subsequent installation. Furthermore, during the welding process of the transverse rib steel plate 8, the position of the through hole 81 can be controlled as needed, thereby reducing the manufacturing difficulty.

[0061] In some embodiments, in step S9, the end of the top steel plate 6 facing away from the bolt guide tube 62 has a shear block 61. During the manufacturing process of the top steel plate 6, the machining of the shear block 61 is completed simultaneously. Since the top steel plate 6 and the shear block 61 are an integrated structure, the connection strength between the shear block 61 and the top steel plate 6 can be guaranteed.

[0062] In some embodiments, in step S9, a marking circle is drawn at the position where the bolt guide tube 62 is installed on the top steel plate 6, and the concentricity deviation between the bolt guide tube 62 and the marking circle is no greater than 0.3 mm. This limitation ensures the installation accuracy of the bolt guide tube 62. In this embodiment, the marking circle on the top steel plate 6 can be drawn with reference to the position of the positioning hole 21 on the steel shear key base plate 2, thereby ensuring that the subsequent bolt guide tube 62 is accurately aligned with the positioning hole 21.

[0063] In some embodiments, in step S9, a first side steel plate 51 is provided between adjacent longitudinal rib steel plates 5. The first side steel plate 51 is perpendicularly welded to the shear key base plate 2, and the first side steel plate 51 is perpendicularly welded to the end of the adjacent longitudinal rib steel plate 5 away from the middle steel plate 3. A second side steel plate 41 is provided between adjacent longitudinal rib steel plates 5 and the first end steel plate 4. The second side steel plate 41 is perpendicularly welded to the shear key base plate 2, and the second side steel plate 41 is perpendicularly welded to the longitudinal rib steel plate 5 and the end of the first end steel plate 4 away from the middle steel plate 3. A third side steel plate 71 is provided between adjacent longitudinal rib steel plates 5 and the second end steel plate 7. The third side steel plate 71 is perpendicularly welded to the shear key base plate 2, and the third side steel plate 71 is perpendicularly welded to the end of the longitudinal rib steel plate 5 and the second end steel plate 7 away from the middle steel plate 3. By providing the first side steel plate 51, the second side steel plate 41, and the third side steel plate 71, the strength of the steel shear key can be further improved.

[0064] In some embodiments, in step S9, after welding the first side steel plate 51, the second side steel plate 41, and the third side steel plate 71, the weld seam is ground, and after visual inspection and flaw detection, the manufacturing of the steel shear key is completed. Specifically, the first side steel plate 51, the second side steel plate 41, and the third side steel plate 71 are fixed by clips during welding to ensure smooth welding. After welding and inspection, the steel shear key can be labeled, and then the steel shear key can be separated from the positioning device 1 for storage or use.

[0065] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
