Description

Technical Field

[0001] This utility model relates to the field of road guardrail technology, specifically a clamping and straightening device for welding road guardrails. Background Technology

[0002] Road guardrails are traffic safety facilities installed on both sides of roads, in the median strip, or at the edge of sidewalks. They are mainly used to isolate traffic flow, guide vehicle traffic, prevent accidents, and protect the safety of pedestrians and vehicles. Their core function is to reduce the severity of traffic accidents through physical barriers and energy absorption. Road guardrails are the "physical defense line" for traffic safety, and their scientific design is directly related to the accident casualty rate. In the future, with the development of intelligent transportation, "smart guardrails" that incorporate sensors (such as collision warning) may become a new direction.

[0003] During the production of road guardrails, the posts and crossbars need to be welded together. The existing road guardrails are welded manually with inconsistent skill levels, which leads to a certain probability of defects in the welded guardrails. Therefore, a clamping and correction device is needed to fix them during welding to ensure that each guardrail is welded with a high degree of consistency.

[0004] Existing devices lack consistency during manual welding, thus requiring a clamping and straightening device for auxiliary operation to improve the consistency of guardrail welding. Furthermore, the existing devices have insufficient adjustment mechanisms and are too fixed, making it difficult to adjust the height when encountering posts of different heights. Therefore, we propose a clamping and straightening device for road guardrail welding to solve the above problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 An embodiment of this utility model is provided: a clamping and straightening device for welding road guardrails, including a straightening frame 1, a clamping and straightening mechanism 2 provided on the surface of the straightening frame 1, and an adjustment mechanism 3 provided at the bottom end of the straightening frame 1;

[0027] The clamping and correction mechanism 2 includes a first fixing block 210, which is fixed to the surface of the correction frame 1. A connecting rod 220 is inserted inside the first fixing block 210, and a spring 230 is sleeved on the surface of the connecting rod 220. A second fixing block 240 is fixed to the surface of the connecting rod 220. A support column 250 is fixed to the surface of the correction frame 1, and a base 260 is fixed to the bottom end of the support column 250.

[0028] The adjustment mechanism 3 includes a third fixing block 310, which is fixed to the surface of the support column 250. A rotating rod 320 is inserted inside the third fixing block 310. The top end of the rotating rod 320 is sleeved with a support block 330 through a bearing. A fourth fixing block 340 is fixed to the surface of the support block 330, and a fifth fixing block 350 is fixed to the surface of the third fixing block 310.

[0029] The interior of the straightening frame 1 is provided with equally spaced circular through holes, and the interior of the second fixing block 240 is provided with equally spaced circular through holes. The circular through holes of the second fixing block 240 and the circular through holes of the straightening frame 1 are staggered. The side of the spring 230 close to the second fixing block 240 is fixedly connected to the second fixing block 240, and the side of the spring 230 away from the second fixing block 240 is fixedly connected to the first fixing block 210. After the second fixing block 240 moves under the action of the spring 230, it will lock and fix the guardrail post. When the positions of the through holes on the second fixing block 240 and the straightening frame 1 coincide, the guardrail post can be inserted into the through holes inside the second fixing block 240 and the straightening frame 1. The spacing of the circular through holes is the spacing of the guardrail post, which facilitates the welding and positioning of the post.

[0030] The base 260 is fixed to the bottom of the support column 250. The base 260 has a square groove inside, which is convenient for placing some welding tools, making the operation of the device more convenient.

[0031] The third fixing block 310 has a threaded hole inside, and the rotating rod 320 has threads on its surface. The rotating rod 320 is threadedly connected to the third fixing block 310. A rotating block is fixed to the bottom of the rotating rod 320. The rotating block has anti-slip texture to increase friction and facilitate the rotation of the rotating rod 320. The support block 330 is connected to the rotating rod 320 by a bearing and is located at the bottom of the straightening frame 1. The fifth fixing block 350 has a sliding groove inside that matches the fourth fixing block 340. The fourth fixing block 340 is inserted into the fifth fixing block 350. When the rotating rod 320 rotates and moves, the fourth fixing block 340 limits the support block 330 under the action of the fifth fixing block 350, preventing the support block 330 from rotating. The support block 330 moves up and down under the rotation of the rotating rod 320 to adjust the support height at the bottom of the guardrail post, thereby facilitating welding of the guardrail post.

[0032] Working principle: When the device is working, pushing the connecting rod 220 moves the second fixing block 240, aligning its circular through hole with the circular through hole on the straightening frame 1. Then, the guardrail post passes through the second fixing block 240 and the straightening frame 1, causing the bottom of the guardrail post to abut against the support block 330, while the top of the guardrail post protrudes from the second fixing block 240. Releasing the connecting rod 220 allows the second fixing block 240 to hold the post in place under the action of the spring 230. The straightening frame 1 ensures that the spacing between the guardrail posts is fixed and calibrated during welding. At the top of the second fixing block 240, the guardrail post... The protruding height of the post makes it easier to observe because the bottom of the guardrail post abuts against the support block 330. If the top height of the guardrail post is uneven, it is also easier to adjust. Then, the guardrail crossbar is welded to the top of the post, which facilitates the clamping and correction of the guardrail during welding. Rotating the rotating rod 320 moves the support block 330, which can adjust the support height at the bottom of the guardrail post and adjust the protruding height of the guardrail post at the top of the second fixing block 240. When welding some tall guardrail posts, the device can be adjusted to make the welding height more suitable for the user. The above is the complete working principle of this utility model.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
