Description

Technical Field

[0001] This utility model relates to the field of welding technology for steel arch frames and connecting plates, and in particular to a positioning fixture for steel arch frame connecting plates. Background Technology

[0002] The bottom of the I-beams of the tunnel steel arch frame needs to be welded with connecting steel plates to facilitate equipment assembly. In the existing arch frame processing, the accuracy of the positioning of the connecting steel plates directly affects whether the arch frame can be assembled smoothly. If the positioning is inaccurate, bolt holes will often be misaligned on site, resulting in bolts not being able to be installed in full and the arch frame not being straight.

[0003] Application No. 2022222134056 discloses a welding controller for connecting plates of tunnel steel arch frames. By setting up a top plate, left clamping plate, right clamping plate and connecting steel plate and using anchor bolts, it is possible to quickly fit the connection between the steel arch frame and the connecting plate when welding, which reduces the difficulty of operation, improves welding efficiency and welding accuracy.

[0004] This patented device consists of a top plate, a left clamping plate, and a right clamping plate. These components work together to securely clamp the top and outer walls of the steel arch frame. In practical applications, even with uniform connecting plate dimensions, the top, left, and right clamping plates cannot be adjusted in position. Therefore, when using the same equipment, the connecting plates may not be precisely aligned with the center of the steel arch frame. This misalignment leads to welding position displacement, affecting welding quality and the overall stability of the structure. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of current steel arch frame and connecting plate welding, where welding fixation errors affect the welding effect due to different steel arch frame models but the same connecting plate size. Therefore, a positioning fixture for steel arch frame connecting plate is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A positioning fixture for a steel arch frame connecting plate includes a connecting seat. Multiple limiting bolts are provided on the side of the connecting seat. A top plate is connected to the upper end of the other side of the connecting seat. Two adjusting rods are slidably connected to the top plate. An adjusting plate is connected to the upper ends of the two adjusting rods. Two locking plates are slidably connected to the upper surface of the top plate. Each locking plate is equipped with a locking assembly. The lower ends of the two adjusting rods pass through the top plate and are connected to a moving plate. Limiting plates are slidably connected to both sides of the lower surface of the moving plate. Limiting rods are connected to both ends of the limiting plates, and the limiting rods can limit the movement of both sides of the steel arch frame.

[0008] The adjustable plate allows for height adjustment of the moving plate according to different models of steel arch frames. Then, the limiting plate and limiting rod can limit the two sides of the steel arch frame, thereby ensuring that the middle of the connecting plate can be aligned with the steel arch frame, improving the welding quality.

[0009] Preferably, a lead screw is rotatably connected to the adjusting plate, and a sleeve is threaded to the lower end of the lead screw. The lower end of the sleeve passes through the top plate and extends to the lower end of the top plate. The lower end of the sleeve is rotatably connected to the upper surface of the push plate. Two tilting rods are connected to the lower surface of the push plate. Two connecting holes are provided on the moving plate. An tilting hole corresponding to the tilting rod is provided on the limiting plate. The ends of the tilting rods pass through the corresponding connecting holes and tilting holes in sequence and extend to the lower part of the limiting plate.

[0010] The lead screw controls the movement of two tilting rods through the sleeve, thereby controlling the tilting rods on the limiting plates. The two limiting plates limit the sides of the steel arch frame.

[0011] Preferably, the lower surface of the movable plate is provided with two grooves, and sliders are installed in the two grooves. The lower surfaces of the two sliders are connected to the upper surface of the limiting plate.

[0012] Preferably, the locking assembly includes multiple limiting holes provided on the locking plate, and both ends of the adjusting plate are provided with threaded blind holes corresponding to the limiting holes. A locking bolt is installed in one of the limiting holes, and the end of the locking bolt extends into the threaded blind hole on the adjusting plate.

[0013] The locking assembly locks the adjusting plate, and the position of the adjusting plate is adjusted according to the signal from the steel arch frame.

[0014] Preferably, the lower ends of both tilting rods are connected to limit blocks.

[0015] The limit block prevents the tilting rod from moving out of the limit plate.

[0016] Preferably, the connecting seat has an opening in the middle.

[0017] Compared with the prior art, the beneficial effects of this utility model are: by cooperating with the adjusting plate, the moving plate and the two limiting plates, the steel arch frame can be limited according to different models, thereby aligning the connecting plate with the middle of the steel arch frame, which facilitates subsequent welding and improves welding quality. By setting the locking plate and the limiting hole, the position of the moving plate can be quickly adjusted according to the position of the steel arch frame. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0026] Reference Figures 1-5A positioning fixture for a steel arch frame connecting plate includes a connecting seat 1. Multiple limiting bolts 16 are provided on the side of the connecting seat 1. The limiting bolts 16 can also be in the form of long rods. The limiting bolts 16 correspond to the holes on the connecting plate, allowing for quick positioning of the connecting plate on the connecting seat 1. An opening 19 is provided in the middle of the connecting seat 1. The opening 19 ensures that the end of the steel arch frame is aligned with the surface of the connecting seat 1, facilitating contact between the end of the steel arch frame and the side of the connecting plate. A top plate 6 is connected to the upper end of the other side of the connecting seat 1. Two adjusting rods 4 are slidably connected to the top plate 6, and the upper ends of the two adjusting rods 4 are connected to an adjusting plate. 3. Two locking plates 5 are slidably connected to the upper surface of the top plate 6. Each locking plate 5 is equipped with a locking component, which can fix the adjusting plate 3. The position of the adjusting plate 3 can be adjusted according to the height of different steel arch frames, thereby driving the position of the moving plate 10 to be adjusted together. The lower ends of the two adjusting rods 4 pass through the top plate 6 and are connected to the moving plate 10. Limiting plates 13 are slidably connected to both sides of the lower surface of the moving plate 10. Limiting rods 2 are connected to both ends of the limiting plates 13. The limiting rods 2 can limit the two sides of the steel arch frame and limit the left and right positions of the steel arch frame to ensure that the middle of the connecting plate corresponds to the middle of the steel arch frame.

[0027] Reference Figure 1 , Figure 2 and Figure 4 A lead screw 7 is rotatably connected to the adjusting plate 3. The lead screw 7 is connected to the adjusting plate 3 via a bearing. A sleeve 8 is threadedly connected to the lower end of the lead screw 7. The lower end of the sleeve 8 passes through the top plate 6 and extends to the lower end of the top plate 6. The lower end of the sleeve 8 is rotatably connected to the upper surface of the push plate 11. Two tilting rods 12 are connected to the lower surface of the push plate 11. The lower ends of the two tilting rods 12 are connected to limit blocks 20. The moving plate 10 is provided with two connecting holes. The bracket of the connecting hole is larger than the diameter of the lower tilting hole 18 to facilitate the tilting rods 12 passing through the connecting holes. The limit plate 13 is provided with tilting holes 18 corresponding to the tilting rods 12. The ends of the tilting rods 12 pass through the corresponding holes in sequence. The connecting hole and the inclined hole 18 extend to the bottom of the limiting plate 13. The rotation of the lead screw 7 controls the sleeve 8 to move downward. The sleeve 8 pushes the push plate 11 to move downward. The corresponding inclined rod 12 pushes the limiting plate 13 to move. The lower surface of the moving plate 10 is provided with two sliding grooves 17. The two sliding grooves 17 are equipped with sliders 15. The lower surfaces of the two sliders 15 are connected to the upper surface of the limiting plate 13. The sliders 15 facilitate the sliding of the limiting plate 13 and support the limiting plate 13. The two limiting plates 13 drive the two limiting rods 2 to limit the left and right sides of the steel arch frame. This ensures that the position of the connecting plate and the steel arch frame corresponds and ensures the quality of welding.

[0028] Reference Figure 1 and Figure 2The locking assembly includes multiple limiting holes 9 on the locking plate 5. Both ends of the adjusting plate 3 are provided with threaded blind holes corresponding to the limiting holes 9. A locking bolt 14 is installed in one of the limiting holes 9. The end of the locking bolt 14 extends into the threaded blind hole on the adjusting plate 3. The locking bolt 14 fixes the adjusting plate 3 to the locking plate 5. The position of the limiting holes 9 on the locking plate 5 can be set according to the model of the steel arch frame, and the number of limiting holes 9 can be set according to the model of the steel arch frame.

[0029] When using the steel arch frame, first determine the model of the steel arch frame, loosen the locking bolt 14, and then move the adjusting plate 3. The adjusting plate 3 drives the two adjusting rods 4 to move together, and the adjusting rods 4 drive the lower moving plate 10 to move. After the movement is complete, the lower surface of the moving plate 10 will abut against the upper surface of the steel arch frame. Fix the adjusting plate 3 with the locking bolt 14. Then, pass the hole of the connecting plate to be welded through the limiting bolt 16 so that the connecting plate abuts against the end face of the steel arch frame. Push the connecting seat 1 through the connecting plate. The connecting seat 1 moves and abuts against the end face of the steel arch frame. Rotate the screw 7. The screw 7 drives the sleeve 8 to move downward. The sleeve 8 pushes the push plate 11 to move downward. The movement of the push plate 11 will cause the tilting rod 12 to squeeze the limiting plate 13. The two limiting plates 13 together squeeze the side of the steel arch frame. At the same time, the two limiting rods 2 on one limiting plate 13 will also limit the side of the steel arch frame.
