Detailed Implementation

[0023] 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.

[0024] Please see Figures 1-3 This utility model provides a cross-road construction welding slag protection platform, including a protection mechanism 100 and a moving mechanism 200 for shielding welding slag during cross-road construction. A support mechanism 300 is provided between the protection mechanism 100 and the moving mechanism 200 for support, and a lifting mechanism 400 for height adjustment is provided between the support mechanism 300 and the moving mechanism 200. The moving mechanism 200 is provided with a counterweight 500 for increasing the weight of the cross-road construction welding slag protection platform to maintain balance. The protection mechanism 100 includes components that can connect with the cross-road highway side. The protective plate 110 has two symmetrically arranged side plates 120 integrally formed on the side facing the moving mechanism 200. The side plates 120 are perpendicular to the protective plate 110. The lower part of the protective plate 110 facing the moving mechanism 200 is fixedly connected to an overlap strip 130 that can contact the road surface of the cross-road highway. The two sides of the overlap strip 130 are fixedly connected to the two side plates 120 respectively. The horizontal line of the bottom of the side plate 120 is higher than the horizontal line of the bottom of the protective plate 110. The support mechanism 300 is provided on the protective plate 110.

[0025] Among them, the moving mechanism 200 includes a first frame 210. Moving wheels 220 are installed at the four corners of the bottom of the first frame 210. Through the moving mechanism 200, the installation foundation of the cross-road construction welding slag protection platform can be formed, and at the same time, the flexibility of the cross-road construction welding slag protection platform can be improved, facilitating the movement of the cross-road construction welding slag protection platform to the required position according to actual use requirements.

[0026] Among them, a first connecting rod 211 is fixedly connected to the inner cavity of the first frame 210. The first connecting rod 211 and the first frame 210 form a "day" - shaped structure. A plurality of counterweight blocks 500 are stacked together on the first frame 210 and the first connecting rod 211. Through the moving wheels 220, the firmness of the first frame 210 can be improved, and the support stability of the counterweight blocks 500 can also be improved.

[0027] Among them, the support mechanism 300 includes a second frame 310. Two symmetrically arranged support rods 320 are fixedly connected to the front side of the bottom of the second frame 310. The support rods 320 and the second frame 310 are perpendicularly arranged. At least two hoop fasteners 330 are installed up and down on the surface of the support rods 320 by bolts. The hoop fasteners 330 are fixedly connected to the side of the protection plate 110 away from the first frame 210. The lifting mechanism 400 is arranged between the second frame 310 and the first frame 210. By using the support mechanism 300 and the lifting mechanism 400 in cooperation, the connection between the protection mechanism 100 and the moving mechanism 200 can be realized to ensure the stability when using the protection mechanism 100.

[0028] Among them, the lifting mechanism 400 includes two telescopic members symmetrically arranged between the second frame 310 and the first frame 210. A second connecting rod 430 is arranged between the two telescopic members. The top of the second connecting rod 430 is fixedly connected to a cylinder 440. The output end of the cylinder 440 is fixedly connected to the second frame 310. By starting the cylinder 440, the output end of the cylinder 440 can drive the support mechanism 300 and the protection mechanism 100 to move up and down synchronously to achieve the lifting effect. That is, when not in use, the protection mechanism 100 can be gradually moved away from the cross-road highway, thus facilitating the movement of the cross-road construction welding slag protection platform; when in use, the protection mechanism 100 can be gradually moved closer to the cross-road highway, thereby facilitating the shielding protection of the road surface steel bar welding.

[0029] The telescopic component includes an outer tube 410 fixedly connected to the top of the first frame 210. The two ends of the second connecting rod 430 are respectively fixedly connected to the two outer tubes 410. An inner rod 420 is slidably provided through the inner cavity of the outer tube 410. The top end of the inner rod 420 is fixedly connected to the second frame 310. When the output end of the cylinder 440 drives the support mechanism 300 to move, the support mechanism 300 can also drive the inner rod 420 to slide in the inner cavity of the outer tube 410 to achieve the limiting effect on the support mechanism 300, which helps to improve the stability of the support mechanism 300 when it is raised and lowered, and avoids shaking or deviation.

[0030] Among them, the inner rod 420 and the second frame 310, and the support rod 320 and the second frame 310 are respectively fixedly connected by two inclined first reinforcing rods 600. The two first reinforcing rods 600 on the inner rod 420 are respectively located on two adjacent vertical planes of the inner rod 420, and the two first reinforcing rods 600 on the support rod 320 are respectively located on two adjacent vertical planes of the support rod 320. The first reinforcing rods 600 can improve the firmness of the connection between the inner rod 420 and the second frame 310, and between the support rod 320 and the second frame 310, which helps to improve the support stability of the support mechanism 300 and the lifting mechanism 400.

[0031] Among them, two inclined second reinforcing rods 700 are fixedly connected between the outer tube 410 and the first frame 210. The two second reinforcing rods 700 on the outer tube 410 are symmetrically arranged. The second reinforcing rods 700 can improve the firmness of the connection between the outer tube 410 and the first frame 210, and further improve the support stability of the moving mechanism 200 and the lifting mechanism 400.

[0032] The working principle of this utility model is as follows: the moving wheel 220 moves the cross-road construction welding slag protection platform to the required position, the cylinder 440 is activated, and the output end of the cylinder 440 drives the second frame 310 to move downward. The second frame 310 drives the support rod 320, the protection mechanism 100, the inner rod 420 and the first reinforcing rod 600 to move downward simultaneously. The inner rod 420 slides in the inner cavity of the outer tube 410 until the protection plate 110 contacts the side of the cross-road expressway and the lap strip 130 contacts the road surface of the cross-road expressway. A part of the road surface steel bars to be welded is located between the two side plates 120. At this time, the workers can be positioned between the road surface steel bars and the first frame 210 to perform welding operations on the road surface steel bars between the two side plates 120. Dangerous materials such as slag or sparks generated during the welding process will be shielded and protected by the protection mechanism 100, thus ensuring the safety of traffic and pedestrians on the expressway under the cross-road expressway.

[0033] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
