Description

Technical Field

[0001] The utility model relates to the field of guardrail welding, in particular to a mobile road guardrail welding device. Background Art

[0002] This mobile road guardrail welding equipment is a specialized, flexible, and highly mobile device designed specifically for road guardrail welding operations. Through structural optimization and integrated functionality, it addresses the challenges of traditional welding equipment, such as the inconvenience of movement and poor adaptability, when welding outdoor guardrails.

[0003] Road guardrail welding is an important part of road construction. Traditional guardrail welding is often done manually, which is easily affected by the operator's technical level and fatigue, resulting in welding misalignment or unstable quality. Although some existing welding equipment uses a clamping mechanism, it is necessary to first fix the vertical and horizontal guardrails one by one and then weld them in sequence, which has low welding efficiency. In addition, the traditional fixing method has difficulty in controlling the distance between the guardrails and has poor adaptability to guardrails of different specifications, making it difficult to meet the diverse guardrail design and construction needs. In view of this, we propose a road guardrail welding equipment that is easy to move. Utility Model Content

[0004] The purpose of this utility model is to solve the above shortcomings and provide a road guardrail welding device that is easy to move, which solves the problems of existing road guardrail welding, such as unstable manual welding quality, difficulty in controlling the distance between railings by traditional fixing methods, poor adaptability to railings of different specifications, and thus difficulty in meeting diverse construction needs;

[0005] To achieve the above-mentioned object, the utility model provides a road guardrail welding device that is easy to move, including a mobile welding table, wherein a V-shaped sliding track is provided inside the mobile welding table, and the mobile welding table is slidably connected to a limiting mechanism through the sliding track;

[0006] The limiting mechanism includes a bidirectional threaded rod located inside the sliding track, and two groups of sliding frames are symmetrically distributed at both ends of the bidirectional threaded rod, which are used to fix the guardrail in a position suitable for welding as needed. Both ends of the two groups of sliding frames are fixedly connected with clamping parts for elastically clamping the guardrail.

[0007] The beneficial effects of the utility model are:

[0008] In the utility model, through the linkage adjustment of the two-way threaded rod and the sliding frame in the V-shaped sliding track, the opposite or opposite movement of the two sets of sliding frames can be accurately controlled to realize the rapid positioning of the horizontal railing at the preset point of the vertical railing. When the two-way threaded rod drives the sliding frame to adjust to the target position, the elastic clamping part is reset by its own elastic force, and can adapt to horizontal railings of different calibers and form a firm clamp, which avoids the deviation of manual positioning and eliminates the tedious steps of traditionally fixing railings one by one, so that the adjustment of the horizontal railing spacing and the guardrail fixing process are completed simultaneously, which not only improves the versatility of the installation of railings of different specifications, but also effectively shortens the preparation time before welding, and cooperates with the robotic arm for continuous welding.

[0009] As a further improvement of the present technical solution, the two groups of sliding frames are adapted to the V-shaped sliding track, and the interior of the bottom ends of the two groups of sliding frames are provided with threads adapted to the bidirectional threaded rod, and the clamping member includes a first clamping block fixedly connected to the sliding frame, and an elastic damping rod is fixedly connected to one side of the bottom of the first clamping block, and the first clamping block is elastically connected to the second clamping block through the elastic damping rod, and the first clamping block and the second clamping block are both arc-shaped and used to clamp the horizontal railing, and the bottoms of the first clamping block and the second clamping block slide in the sliding track and are adapted to the sliding track.

[0010] The beneficial effect of adopting the above-mentioned further scheme is that the arc-shaped first and second clamping blocks, in conjunction with the elastic damping rod, can adapt to horizontal railings of different calibers, achieve firm clamping through elastic resetting, and enhance versatility; at the same time, the bottom of the clamping block is adapted to the sliding track, so that the clamping process and positioning are carried out simultaneously, simplifying the operation process and greatly improving the efficiency and stability of road guardrail welding.

[0011] As a further improvement of the present technical solution, arc-shaped fixing grooves are fixedly connected on both sides of the mobile welding table, and both ends of the arc-shaped fixing grooves are fixedly connected with collars by bolts for fixing the ends of the vertical railings, and the arc-shaped fixing grooves and the collars are tightly fitted with the outer walls of the vertical railings, and both ends of the bidirectional threaded rods are rotatably connected with stabilizing plates through bearings, and the stabilizing plates are fixedly connected to the mobile welding table, one end of the bidirectional threaded rod passes through one of the stabilizing plates and is fixedly connected to a rotating handle, a robotic arm is installed on the top of one end of the mobile welding table, and a welding gun is installed at one end of the robotic arm.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the arc-shaped fixing grooves and the rings on both sides of the mobile welding table fit tightly with the ends of the vertical railings. By fixing with bolts, the vertical railings can be installed quickly and firmly, providing stable support for the overall welding. The two-way threaded rods are connected to the stabilizing plate with the help of bearings to ensure smooth rotation. With the rotating handle, the operator can easily adjust and accurately control the position of the sliding frame to flexibly fix the horizontal railings.

[0013] Through the linkage adjustment mechanism of the bidirectional threaded rod and the sliding frame, precise positioning and rapid fixation between the horizontal railing and the vertical railing can be achieved during the welding process, thus forming a continuous and stable welding operation process. When the bidirectional threaded rod is rotated, the two sets of sliding frames move synchronously toward or in opposite directions, driving the clamping parts to accurately align to the preset welding points, greatly shortening the time required for traditional adjustment of railings one by one, and improving the efficiency of welding preparation work; at the same time, the elastic reset structure of the clamping parts can automatically clamp the horizontal railing after release, ensuring that it remains stable and does not deviate during the welding process, avoiding misalignment problems caused by improper human operation or mechanical vibration, and further ensuring the consistency and reliability of welding quality.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The utility model provides the following preferred embodiments

[0024] See also Figure 1-Figure 4As shown, this embodiment provides a road guardrail welding device that is easy to move, including a mobile welding platform 100, a V-shaped sliding track 101 is opened inside the mobile welding platform 100, and the mobile welding platform 100 is slidably connected to the limiting mechanism 200 through the sliding track 101;

[0025] The limiting mechanism 200 includes a bidirectional threaded rod 201 located inside the sliding track 101. Two groups of sliding frames 202 are symmetrically distributed at both ends of the bidirectional threaded rod 201, which are used to fix the guardrail in a position suitable for welding as needed. Both ends of the two groups of sliding frames 202 are fixedly connected with clamping parts 203 for elastically clamping the guardrail.

[0026] The improvement of this embodiment is that:

[0027] During the guardrail welding process, manual welding is usually adopted or the guardrail is fixed with a clamping mechanism, and then the welding gun is driven by the robot arm 300 to perform welding. However, manual welding is easily affected by human factors such as the operator's technical level and fatigue, resulting in welding misalignment or unstable quality. When using a clamping mechanism, the vertical and horizontal railings must be fixed one by one, and then welded in sequence, resulting in low welding efficiency and difficulty in achieving continuous automated operation. Therefore, when installing the road guardrail, the two-way threaded rod 201 is rotated to drive the two sets of sliding frames 202 to move toward or in opposite directions along the rod body, so that it moves to the appropriate position, thereby accurately fixing the horizontal railing at the preset point of the vertical railing. The cross railings are then positioned in the same direction as above, and then the clamping parts 203 are moved to both sides to place the cross railings inside. After the clamping parts 203 are released, they are reset by their own elastic force to achieve a firm fixation of the cross railings. The cooperation between the two-way threaded rod 201 and the sliding frame 202 can flexibly adjust the installation position of the cross railings, and the spacing between the cross railings of the road guardrail can be freely designed according to actual needs. Moreover, the elastic and adaptive design of the clamping parts 203 enables it to adapt to cross railings of different calibers, which significantly improves the versatility and compatibility of the installation structure, reduces the difficulty of construction, improves the efficiency and flexibility of road guardrail installation, and meets the diverse guardrail design and construction needs.

[0028] On the basis of the above, the specific structure is disclosed in detail:

[0029] To achieve stability during welding of road guardrails, the limiting mechanism 200 is disclosed in detail, such as Figure 3 and Figure 2As shown, the two sets of sliding frames 202 are adapted to the V-shaped sliding track 101, and the bottom ends of the two sets of sliding frames 202 are provided with threads adapted to the bidirectional threaded rod 201. The clamping member 203 includes a first clamping block 2031 fixedly connected to the sliding frame 202, one side of the bottom of the first clamping block 2031 is fixedly connected to an elastic damping rod 2032, and the first clamping block 2031 is elastically connected to the second clamping block 2033 through the elastic damping rod 2032. When connecting the work, first rotate the two-way threaded rod 201 to drive the two sets of sliding frames 202 to move along the rod body and adjust them to the precise position suitable for welding the horizontal railing. Then, move the first clamping block 2031 and the second clamping block 2033 to both sides respectively, leaving space, and place the horizontal railing between the two. After loosening the clamping blocks, the elastic damping rod 2032 comes into play, driving the second clamping block 2033 to reset, thereby tightly clamping the horizontal railing and ensuring the stability of the horizontal railing during welding.

[0030] Specifically, the first clamp 2031 and the second clamp 2033 are both arc-shaped and used to clamp the horizontal railing, and the bottom of the first clamp 2031 and the second clamp 2033 slide in the sliding track 101 and are adapted to the sliding track 101. The sliding track 101 constrains the trajectory of the first clamp 2031 and the second clamp 2033 when they move. The first clamp 2031 and the second clamp 2033 are located at the top of the sliding track 101, which also prevents the second clamp 2033 from falling.

[0031] It is worth mentioning that in order to achieve the limitation of the horizontal railing, the two sides of the mobile welding platform 100 must be fixedly connected with an arc-shaped fixing groove 102, and both ends of the arc-shaped fixing groove 102 are fixedly connected with a ring by bolts to fix the end of the vertical railing, and the arc-shaped fixing groove 102 and the ring are tightly fitted with the outer wall of the vertical railing. The vertical railing is placed inside the arc-shaped fixing groove 102, the bolts are tightened, and the end of the vertical railing is fixed by the ring, which is conducive to limiting the vertical railing. Through the cooperation of the arc-shaped fixing groove 102 and the limiting mechanism 200 (the limiting mechanism 200 is used to fix the horizontal railing), the stability of the horizontal railing and the vertical railing during welding is guaranteed.

[0032] Furthermore, to realize the rotation of the bidirectional threaded rod 201, the specific Figure 3 and Figure 4 As shown, both ends of the bidirectional threaded rod 201 are rotatably connected to a stabilizing plate through bearings, and the stabilizing plate is fixedly connected to the mobile welding table 100. One end of the bidirectional threaded rod 201 passes through one of the stabilizing plates and is fixedly connected to a rotating handle 204. The operator manually rotates the rotating handle 204, thereby driving the bidirectional threaded rod 201 to rotate. The rotating handle 204 provides power for the rotation of the bidirectional threaded rod 201.

[0033] However, to realize the welding of road guardrails, the details are as follows Figure 4 As shown, a robotic arm 300 is installed on the top of one end of the mobile welding table 100, and a welding gun is installed at one end of the robotic arm 300. When using the robotic arm 300 to weld the railing, the welding point position and trajectory are first set through programming or teaching. The multi-degree-of-freedom joints (such as axes) of the robotic arm 300 are driven by servo motors to drive the end welding gun to move along a preset path. The welding system outputs adaptive current, voltage and other parameters according to the material of the railing. The visual or force sensor corrects the position and posture in real time to ensure that the welding gun is accurately aligned with the weld seam, realizing automated welding, and at the same time monitoring the welding quality to ensure efficiency and stability. The robotic arm 300 and the welding gun are existing technologies and will not be described in detail.

[0034] Finally, the welding gun on the top mechanical arm 300 of one end of the mobile welding platform 100 is started to perform welding operation on the fixed horizontal railing and the vertical railing.

The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
