Description

Technical Field

[0001] This utility model relates to the field of height restriction frame production technology, specifically a fixing structure for welding and producing road height restriction frames. Background Technology

[0002] The fixing structure for road height restriction frame welding production is used in the welding production of road height restriction frames. Its core function is to position the crossbeams, columns and other components of the height restriction frame. By clamping and fixing each welding component, displacement and deformation during the welding process are prevented, ensuring the assembly accuracy of components and the quality of welding joints. At the same time, it improves the safety of welding operations and production efficiency, adapts to the welding processing needs of different specifications of height restriction frames, and ensures that the finished product meets the structural strength requirements for road traffic height restriction protection.

[0003] In the welding production of road height restriction frames, traditional assembly and fixing methods often rely on manual positioning and temporary support. This method, which relies on manual pressing and simple fixing, may cause installation errors due to slight displacement of components during the welding process, thus affecting the dimensional consistency of the final structure. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a fixed structure for welding production of road height restriction frames, which can ensure the stability of the component position during the welding process by adjusting the components, improve the welding accuracy and structural consistency of the height restriction frame, simplify the installation and positioning process, and improve the welding operation efficiency.

The adjustment assembly includes: a lifting rod, a limiting block a, and a limiting block b. A lifting rod is disposed at the top of the horizontal plate, a limiting block a is connected to the top of the lifting rod, the limiting block b is located at the bottom of the horizontal bar, a limiting block b used in conjunction with the limiting block a is disposed at the top of the horizontal bar, and the horizontal bar is located between the limiting block a and the limiting block b.

[0007] Preferably, a handwheel is provided at the bottom of the horizontal plate, one end of the handwheel is connected to a rotating rod, one end of the rotating rod extends into the interior of the lifting rod, a guide groove is provided on one side of the lifting rod, a guide rod is connected to one side of the clamping block b, and one end of the guide rod extends into the interior of the guide groove.

[0016] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0017] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0018] like Figures 1-4 As shown, a fixing structure for welding and producing road height restriction frames includes: a height restriction horizontal bar 1, a height restriction vertical bar 101 at the bottom of the height restriction horizontal bar 1, a clamping block a102 on one side of the height restriction vertical bar 101, a clamping block b103 on one side of the height restriction vertical bar 101, the inner walls of clamping blocks a102 and b103 fitting against the outer side of the height restriction vertical bar 101, a horizontal plate 104 connected to one side of clamping block b103, and an adjustment assembly disposed on the outer side of the height restriction horizontal bar 1 for adjusting the height restriction during welding. The height-limiting horizontal bar 1 and the height-limiting vertical bar 101 are fixed. The adjustment assembly includes: a lifting bar 2, a limiting block a201 and a limiting block b202. The lifting bar 2 is provided on the top of the horizontal plate 104. The limiting block a201 is connected to the top of the lifting bar 2. The limiting block b202 is located at the bottom of the height-limiting horizontal bar 1. The limiting block b202, which is used in conjunction with the limiting block a201, is provided on the top of the height-limiting horizontal bar 1. The height-limiting horizontal bar 1 is located between the limiting block a201 and the limiting block b202.

[0019] The adjustment assembly utilizes the lifting rod 2, limiting block a201, and limiting block b202 to lift the height-limiting horizontal bar 1 and position it in conjunction with the height-limiting vertical bar 101. This avoids component displacement caused by manual pressing, reduces welding deformation and installation errors. The clamping blocks a102 and b103 fix the height-limiting vertical bar 101, and the limiting blocks a201 and b202 fix the height-limiting horizontal bar 1, ensuring the stability of the component position during welding. This improves the welding accuracy and structural consistency of the height-limiting frame, simplifies the installation and positioning process, and increases welding efficiency.

[0020] The bottom of the horizontal plate 104 is provided with a handwheel 3, one end of which is connected to a rotating rod 301. One end of the rotating rod 301 extends into the lifting rod 2. The lifting rod 2 has a lifting groove 4 inside, and a threaded rod 401 is provided inside the lifting groove 4. The outer side of the threaded rod 401 is threadedly connected to the inner wall of the lifting groove 4. One end of the threaded rod 401 is connected to the top of the rotating rod 301. A guide groove 5 is provided on one side of the lifting rod 2, and a guide rod 501 is connected to one side of the clamping block b103. One end of the guide rod 501 extends into the guide groove 5.

[0021] First, attach clamping blocks a102 and b103 to the outside of the height-limiting vertical bar 101, and use four bolts a601 to pass through the corresponding threaded holes a6 and tighten the nuts to fix them firmly to the vertical bar, so that the horizontal plate 104 connected to clamping block b103 is in a state parallel to the height-limiting horizontal bar 1.

[0022] Furthermore, the height-limiting horizontal bar 1 is placed on top of the height-limiting vertical bar 101, and the weld joints are aligned. At this time, the handwheel 3 is rotated, which drives the rotating rod 301 and the threaded rod 401 at the top to rotate. Due to the threaded connection between the outer side of the threaded rod 401 and the inner lifting groove 4 of the lifting rod 2, and the sliding engagement between the lifting rod 2 and the guide rod 501 on the clamping block b103 through the guide groove 5 on one side, the rotation of the threaded rod 401 is converted into the vertical lifting of the lifting rod 2, thereby adjusting the height of the top limiting block a201 of the lifting rod 2, so that the clamping block 702 inside the limiting block a201 presses against the bottom of the height-limiting horizontal bar 1.

[0023] Each clamping block a102 and clamping block b103 has four threaded holes a6 inside. Each clamping block a102 has four bolts a601 on one side. One end of each bolt a601 passes through the corresponding clamping block a102 and clamping block b103 and is threaded with a nut. Each limiting block a201 and limiting block b202 has four threaded holes b7 inside. Each limiting block b202 has four bolts b701 on the top. One end of each bolt b701 passes through the limiting block a201 and limiting block b202 and is threaded with a nut. Each limiting block a201 and limiting block b202 has a clamping block 702 on its inner side. The inner walls of both clamping blocks 702 are in contact with the outer side of the height limiting crossbar 1.

[0024] Finally, four bolts b701 are used to pass through the threaded holes b7 on the limiting block a201 and the limiting block b202 and tighten them. The height limiting crossbar 1 is locked by the clamping block 702 on the inner side. This achieves the positioning and firm fixation of the height limiting crossbar 1 and the height limiting vertical bar 101 before welding, thereby improving the welding efficiency of the welders.

[0025] Working principle:

[0026] First, attach clamping blocks a102 and b103 to the outside of the height-limiting vertical bar 101, and use four bolts a601 to pass through the corresponding threaded holes a6 and tighten the nuts to fix them firmly to the vertical bar, so that the horizontal plate 104 connected to clamping block b103 is in a state parallel to the height-limiting horizontal bar 1.

[0027] Furthermore, the height-limiting horizontal bar 1 is placed on top of the height-limiting vertical bar 101, and the weld joints are aligned. At this time, the handwheel 3 is rotated, which drives the rotating rod 301 and the threaded rod 401 at the top to rotate. Due to the threaded connection between the outer side of the threaded rod 401 and the inner lifting groove 4 of the lifting rod 2, and the sliding engagement between the lifting rod 2 and the guide rod 501 on the clamping block b103 through the guide groove 5 on one side, the rotation of the threaded rod 401 is converted into the vertical lifting of the lifting rod 2, thereby adjusting the height of the top limiting block a201 of the lifting rod 2, so that the clamping block 702 inside the limiting block a201 presses against the bottom of the height-limiting horizontal bar 1.

[0028] Finally, four bolts b701 are used to pass through the threaded holes b7 on the limiting block a201 and the limiting block b202 and tighten them. The height limiting crossbar 1 is locked by the clamping block 702 on the inner side. This achieves the positioning and firm fixation of the height limiting crossbar 1 and the height limiting vertical bar 101 before welding, thereby improving the welding efficiency of the welders.
