Abstract
Description
Technical Field
[0001] This utility model relates to the field of falling object protection technology, and in particular to a multifunctional anti-collision wall casting device for preventing falling objects. Background Technology
[0002] Crash barriers are structural facilities used in civil engineering to protect against vehicle collisions, primarily in bridges, highways, and other similar applications. Their core functions include preventing vehicles from crossing boundaries, separating traffic flows, and buffering collision impacts. Common structural forms include cast-in-place concrete walls, precast components, and composite protection systems, with materials including reinforced concrete and hollow bricks.
[0003] Currently, most construction projects involving the pouring of crash barriers for viaducts lack mechanisms to prevent falling objects. This results in construction equipment and building debris such as sand and gravel easily falling from the viaducts during construction, posing safety hazards to vehicles and pedestrians traveling below.
[0004] Therefore, this application proposes a multifunctional anti-collision wall casting anti-falling object device. Utility Model Content
[0005] This utility model discloses a multifunctional anti-collision wall pouring anti-falling object device, which aims to solve the technical problem of falling object risk in existing anti-collision wall construction.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A multifunctional anti-collision wall casting anti-falling object device includes a mounting base plate, and the upper surface of the mounting base plate is rotatably connected to a connecting vertical plate and a side baffle plate via a rotating shaft;
[0008] The upper surface of the mounting base plate is embedded with two symmetrical arc-shaped plates, and the surface of the arc-shaped plates is provided with arc-shaped slots. The front and back of the side baffle are fixedly connected to the first screw through the arc-shaped slots. The surface of the first screw is threaded with the first nut. The lower surface of the mounting base plate is provided with a reinforcing mechanism, and the inside of the side baffle is provided with an expansion mechanism.
[0009] In a preferred embodiment, the upper surface of the mounting base plate is rotatably connected to two symmetrical connecting rods via a rotating seat. The surface of the connecting rods is provided with a sliding strip opening, and the front and back of the connecting vertical plate are both fixedly connected to connecting slide rods via the sliding strip openings.
[0010] By setting up connecting rods, the load-bearing strength between the connecting vertical plate and the mounting base plate can be increased without affecting their flexible rotation, thus avoiding the weight being entirely exerted on the rotation axis between the connecting vertical plate and the mounting base plate.
[0011] In a preferred embodiment, the reinforcement mechanism includes several mounting frames fixedly installed on the lower surface of the mounting base plate, with a levering abutment connected slidably inside the mounting frames.
[0012] By using the support rods, the load-bearing strength of the mounting base plate can be increased by utilizing the bridge structure.
[0013] In a preferred embodiment, a limiting slider is provided on the lower surface of the lever, and a limiting groove is provided on the inner bottom wall of the mounting frame for the limiting slider to slide.
[0014] By setting a limit slider, the slippage of the lever inside the mounting frame can be prevented under the limiting action of the limit slider.
[0015] In a preferred embodiment, a connecting ring is fixedly installed on the surface of the arc-shaped plate, and a sling is fitted on the surface of the connecting ring. A cement nail is provided at the end of the sling away from the connecting ring.
[0016] The stability of the fall arrestor can be further improved by using slings and cement nails, which can be connected to the bridge structure.
[0017] In a preferred embodiment, the surface of the connecting vertical plate is provided with a plurality of equally spaced screw holes, and the inner wall of the screw holes is threaded with mounting bolts.
[0018] In a preferred embodiment, the extension mechanism includes a storage slot formed on the upper end of the side baffle, a display plate slidably connected inside the storage slot, an installation slot extending through the storage slot on the left side surface of the side baffle, a second screw fixedly connected to the left side surface of the display plate through the installation slot, and a second nut threadedly connected to the surface of the second screw.
[0019] By setting up display panels, the interception range of the side barriers against falling objects can be increased, thereby improving their protective effect.
[0020] As can be seen from the above, the multifunctional anti-collision wall pouring anti-falling object device provided by this utility model has the following technical effects.
[0021] Firstly, the connecting vertical plate is fixed to the side wall of the bridge structure using installation bolts, and the slings are fixed to the surface of the bridge structure using cement nails. Then, the levering rod is pulled out from the installation frame, so that the levering rod abuts against the lower surface of the bridge structure, thus completing the installation of the device. With the action of the side baffle and the installation base plate, a ring of falling object protection can be formed at the edge of the bridge structure to ensure the safety of vehicles and people passing under the bridge.
[0022] Secondly, loosening the second nut on the surface of the second screw allows the extension plate to extend into the storage slot without the restriction of the second nut, thus expanding the receiving range of the side baffle and further improving the protective effect of the fall arrestor. After the device is used, loosening the first nut on the surface of the first screw and rotating the side baffle and connecting vertical plate until they are stacked on the mounting base plate reduces its overall volume, making it easier to handle and carry in the future.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0029] Reference Figures 1-4 A multifunctional anti-collision wall casting anti-falling object device includes a mounting base plate 1, and a connecting vertical plate 2 and a side baffle 3 are rotatably connected to the upper surface of the mounting base plate 1 via a rotating shaft.
[0030] The upper surface of the mounting base plate 1 is embedded with two symmetrical arc-shaped plates 4. The surface of the arc-shaped plates 4 is provided with arc-shaped slots. The front and back of the side baffle 3 are fixedly connected to the first screw 5 through the arc-shaped slots. The surface of the first screw 5 is threaded with the first nut. The lower surface of the mounting base plate 1 is provided with a reinforcing mechanism. The inside of the side baffle 3 is provided with an expansion mechanism.
[0031] The upper surface of the mounting base plate 1 is rotatably connected to two symmetrical connecting rods 6 via a rotating seat. The surface of the connecting rods 6 is provided with a sliding strip opening. The front and back of the connecting vertical plate 2 are fixedly connected to connecting slide rods via the sliding strip openings.
[0032] By setting the connecting rod 6, the load-bearing strength between the connecting vertical plate 2 and the mounting base plate 1 can be increased without affecting the flexible rotation between them, and the weight is prevented from being fully applied to the rotation axis between the connecting vertical plate 2 and the mounting base plate 1.
[0033] The surface of the connecting vertical plate 2 has several equally spaced screw holes, and the inner wall of the screw holes is threaded with mounting bolts 12.
[0034] Reference Figure 3 and Figure 4 In a preferred embodiment, the reinforcement mechanism includes a plurality of mounting frames 7 fixedly installed on the lower surface of the mounting base plate 1. The mounting frames 7 are slidably connected with levers 8. By setting the levers 8, the load-bearing strength of the mounting base plate 1 can be improved by means of the bridge structure 15.
[0035] The lower surface of the lever 8 is provided with a limiting slider 9, and the inner bottom wall of the mounting frame 7 is provided with a limiting groove for the limiting slider 9 to slide. Under the limiting action of the limiting slider 9, the lever 8 can be prevented from slipping inside the mounting frame 7.
[0036] A connecting ring is fixedly installed on the surface of the arc plate 4. A sling 10 is sleeved on the surface of the connecting ring. A cement nail 11 is provided at the end of the sling 10 away from the connecting ring. By setting the sling 10 and the cement nail 11, the stability of the anti-fall device can be further improved by connecting the cement nail 11 and the sling 10 to the bridge structure 15.
[0037] Reference Figure 3 and Figure 4 In a preferred embodiment, the extension mechanism includes a storage slot on the upper end of the side baffle 3, with a display plate 13 slidably connected inside the storage slot. The left side surface of the side baffle 3 has an installation slot that extends into the storage slot. A second screw 14 is fixedly connected to the left side surface of the display plate 13 through the installation slot. A second nut is threaded onto the surface of the second screw 14. By setting the display plate 13, the interception range of the side baffle 3 against falling objects can be increased, thereby improving its protective effect.
[0038] Working principle: In use, the connecting vertical plate 2 is fixedly installed on the side wall of the bridge structure 15 by the mounting bolts 12, and the sling 10 is fixed to the surface of the bridge structure 15 by the cement nails 11. Then, the lever 8 is pulled out from the mounting frame 7 so that the lever 8 abuts against the lower surface of the bridge structure 15, thus completing the installation of the device. Under the action of the side baffle 3 and the mounting base plate 1, a ring of falling object protection can be formed at the edge of the bridge structure 15 to ensure the safety of vehicles and personnel passing under the bridge. At the same time, the second nut on the surface of the second screw 14 is loosened. Without the restriction of the second nut, the unfolding plate 13 is pulled down and extended into the storage groove, which can expand the receiving range of the side baffle 3. When the device is finished, the first nut on the surface of the first screw 5 is loosened, and the side baffle 3 and the connecting vertical plate 2 are rotated respectively until they are stacked on the mounting base plate 1, which can reduce its overall volume and facilitate subsequent handling and carrying.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
