Description

Technical Field

[0001] The invention relates to the technical field of construction guardrail welding, and in particular to a road construction guardrail welding device. Background Art

[0002] Municipal road construction guardrail is a facility used to protect road traffic safety and separate traffic. It is usually made of metal materials and installed on both sides or in the middle of the road. It is used to limit vehicle driving areas, prevent pedestrians from entering the road, separate different lanes, etc. In urban roads, guardrails have been widely used as their main and important components. Due to the long urban roads, the guardrails are longer. In order to facilitate transportation, the guardrails are usually shorter. In actual use, the guardrails need to be assembled and welded on site to meet the needs of road guardrails.

[0003] After searching, according to the patent network CN116984885B, a municipal road construction guardrail welding device and welding process, the municipal road construction guardrail welding device includes a column, the middle of the column is provided with a guide groove, the upper and lower ends of the guide groove inner cavity are movably connected with guide blocks, the left and right sides of the column are provided with a slot, the front of the column is provided with a welding assembly between two guide blocks, the welding assembly is movably connected with the slot, the invention is provided with four movable locking assemblies, the fulcrum position can be changed by changing the connecting rod angle and the distance between the two guide blocks, so that it can adapt to guardrails of different specifications, and at the same time, the four fulcrums can be quickly fixed to the guardrail through the external input water flow, so as to realize the rapid splicing and fixation between the two guardrails, avoiding the problem that the traditional device needs frequent adjustment to complete the fixation of the guardrail before welding, and the welding efficiency is high.

[0004] However, although the existing guardrail welding device can adjust the welding operation on guardrails of different sizes when in use, when the guardrail is welded by the welding device, the spark adjustment and shielding effect generated during welding is not high, and when the guardrail is welded by the welding device, the odor adsorption, filtering and discharge effect generated by welding is not high, so that the welding device directly discharges the odor when welding the guardrail, which is likely to cause discomfort to pedestrians and residents in the welding area, and reduce the satisfaction with the guardrail welding construction. When the guardrail is welded by the welding device, the welding device can be fixed and transferred by means of a suction cup, but the guardrail welding area often has more impurities, and the direct adsorption method of the suction cup is likely to cause unstable adsorption between the suction cup and the ground, reducing the stability of the welding device on guardrails at different positions, and does not meet people's use needs.

When the construction guardrail is welded by the welding device, in order to improve the anti-splashing effect of the welding head on the guardrail when welding, the second servo motor can be turned on according to the needs of the protection range. The rotation of the bevel gear group drives the second threaded rod to rotate.

At the same time, the threaded slider 26 slides along the inner wall of the swing groove 29, driving the swing rod 28 to rotate. The rotation of the swing rod 28 drives the protective plate 30 to flip along one side of the welding head 22, which effectively prevents splashes in the welding area and effectively protects pedestrians.

[0055] Next, when the construction guardrail is welded by the welding device, in order to improve the stability of the guardrail during docking and prevent the guardrail from being offset during docking and affecting the welding quality, the fixing block 13 can be pre-positioned and fitted with the guardrail when the guardrail needs to be docked, and the first electric push rod 14 is opened to drive the clamping block 15 to slide along the inner wall of the fixing groove 16, so as to effectively engage and fix the guardrail, and the centering sliding of the sliding frame 6 allows the insert block 4 to be inserted into the inner wall of the slot 5, so as to accurately dock and install the guardrail, thereby improving the welding quality of the guardrail.

[0056] Next, when welding the guardrail through the welding device, in order to improve the effect of effectively adsorbing, filtering and discharging the odor generated by welding and reduce the discomfort of pedestrians and residents in the construction area, the suction fan 36 can be turned on when welding the guardrail through the welding head 22. Under the action of the adsorption port 31, the odor generated by welding is adsorbed into the filter box 32, and under the purification of the two sets of filter screens and the activated carbon adsorption net 34, the purified odor is discharged through the exhaust port 37, so as to achieve the effect of effectively purifying and discharging the odor generated by the guardrail welding;

[0057] Finally, when the guardrail is welded by the welding device, in order to improve the convenience of moving the device position and the stability of welding after the position is moved, when the device needs to be moved, the bolt 3802 can be turned through the limiting effect of the nut 3801 to drive the lifting rod 3803 to slide along the inner wall of the lifting groove 3804 and stretch the spring 3805. At the same time, the universal roller 3806 is driven to move downward synchronously, so that the roller contacts the ground, thereby achieving the effect of driving the welding device to move the welding position conveniently.
