Description

Technical Field

[0001] This utility model relates to the technical field of anti-collision wall construction, specifically a construction device for bridge anti-collision walls. Background Technology

[0002] With the rapid development of society, economy, and transportation, the construction of urban highway bridges is unfolding on a large scale. When constructing highway bridges, crash barriers must be installed to achieve safety protection and reduce traffic accidents.

[0003] Utility model patent CN215859038U discloses a construction device for road and bridge crash barriers, belonging to the technical field of crash barrier construction. It addresses the problem that existing technologies typically involve fixing a template first, then pouring concrete into the template, and finally, the concrete solidifies to form the crash barrier. However, due to the varying template sizes used in different highway bridges, existing construction devices struggle to fix templates of different sizes, leading to cumbersome construction operations. The device includes a base with rollers installed at the bottom and a first motor located at the center of the top. The output of the first motor is connected to a one-way lead screw, which is screwed onto... The device includes a lifting frame with guide rods passing through both sides. The bottom ends of the guide rods are fixedly connected to the top of the base. An adjustment assembly is connected to the top of the lifting frame, and two sets of connecting plates are connected to the adjustment assembly. Two sets of limiting plates are fixedly connected to the bottom of each set of connecting plates. A first motor drives a one-way screw to rotate, and the lifting frame moves along the one-way screw. The lifting frame drives the adjustment assembly to move, and the adjustment assembly drives the limiting plates to move through the connecting plates. The position and height of the limiting plates can be adjusted, and the distance between the two sets of connecting plates can be adjusted, thereby adjusting the distance between the limiting plates at the bottom of the two sets of connecting plates. This facilitates the fixing of templates of different sizes.

[0004] However, the above patent still has shortcomings: although it can fix templates of different sizes, it does not have the function of pouring concrete into the inside of the template. This means that after the template is fixed, workers need to manually pour concrete into the inside of the mold, which increases the workload of workers and results in poor work efficiency.

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.

[0025] Please see Figures 1 to 5 The present invention will describe the above technical solution in detail through the following embodiments:

[0026] A construction device for a bridge crash barrier includes: a base plate 1; a side plate 2 fixedly connected to one side of the top of the base plate 1, a top plate 3 fixedly connected to the top of the side plate 2, a cement box 4 disposed on the side of the side plate 2 away from the base plate 1, a discharge port 5 fixedly connected to the bottom of the cement box 4, and a mold frame 6 fixedly connected to the bottom of the discharge port 5; a mixing mechanism 7 for rapid pouring of the bridge crash barrier is disposed at the bottom of the cement box 4; a lifting mechanism 8 for adjusting the height of the mold frame 6 is disposed at the bottom of the top plate 3. Workers pour concrete into the cement box 4, and then control the cement box 4 and the mold frame 6 to move to the ground through the lifting mechanism 8. Then, the concrete inside the cement box 4 is transported from the discharge port 5 to the inside of the mold frame 6 through the mixing mechanism 7, thereby achieving the purpose of pouring the crash barrier.

[0027] like Figure 2 and Figure 3As shown, the mixing mechanism 7 includes: a fixed frame 9 fixedly connected to the top of the cement tank 4; a hollow tube 10 rotatably connected to the center of the top of the fixed frame 9; a matching drive shaft 11 disposed inside the hollow tube 10; the top end of the drive shaft 11 passes through the gearbox 12 and extends to the first motor 13; the first motor 13 is fixedly connected to the gearbox 12; the gearbox 12 is fixedly connected to the fixed frame 9; an auger blade 14 is fixedly connected to the outer surface of the bottom end of the drive shaft 11; the auger blade 14 is matched with the discharge port 5; three sets of mixing rods 15 are evenly fixedly connected to the outer surface of the hollow tube 10 located inside the cement tank 4; a first bevel gear 16 is fixedly connected to the outer surface of the hollow tube 10 located inside the gearbox 12; a second bevel gear 17 meshes with one side of the first bevel gear 16; a rotating shaft 18 is fixedly connected to the center of the second bevel gear 17; the end of the rotating shaft 18 away from the second bevel gear 17 passes through the gear... The gearbox 12 extends to the second motor 19, which is fixedly connected to the gearbox 12. The rotating shaft 18 is fixedly connected to the output end of the second motor 19. When the second motor 19 is started, its output end drives the rotating shaft 18, which in turn drives the second bevel gear 17. The second bevel gear 17 drives the first bevel gear 16 to rotate. As the first bevel gear 16 rotates, it drives the hollow tube 10, which in turn drives the stirring rod 15. As the stirring rod 15 rotates, it continuously stirs the concrete inside the cement box 4, thereby extending the concrete's setting time. When it is necessary to pour the crash barrier, the first motor 13 is started. Its output end drives the transmission shaft 11, which in turn drives the auger blades 14. As the auger blades 14 rotate, they transport the concrete inside the cement box 4 through the discharge port 5 to the inside of the mold frame 6, thereby achieving the purpose of pouring the crash barrier.

[0028] like Figure 2 and Figure 4 As shown, the lifting mechanism 8 includes: a lifting block 20 is provided at the bottom of the top plate 3, a screw 21 is threadedly connected to the center of the lifting block 20, the bottom end of the screw 21 is rotatably connected to the bottom plate 1, the top end of the screw 21 passes through the top plate 3 and extends to the third motor 22, the third motor 22 is fixedly connected to the top plate 3, and the screw 21 is fixedly connected to the output end of the third motor 22; a connecting frame 23 is fixedly connected to the side of the lifting block 20 away from the side plate 2, and the side of the connecting frame 23 away from the lifting block 20 is fixedly connected to the cement box 4. When the third motor 22 is started, the output end of the third motor 22 drives the screw 21. While the screw 21 rotates, it controls the lifting block 20 to move downward. While the lifting block 20 moves downward, it drives the connecting frame 23. The connecting frame 23 drives the cement box 4. While the cement box 4 moves downward, it drives the mold frame 6 through the discharge port 5, thereby causing the mold frame 6 to descend to the ground.

[0029] like Figure 4As shown, sliding rods 24 are slidably connected to both sides of the lifting block 20. The two ends of the sliding rods 24 are fixedly connected to the bottom plate 1 and the top plate 3 respectively. The sliding rods 24 cooperate with the screw 21 to limit the lifting block 20, thereby controlling the lifting block 20 to perform flexible vertical lifting and lowering movements.

[0030] like Figure 5 As shown, two reinforcing plates 25 are provided on the side of the side plate 2 near the bottom plate 1. The reinforcing plates 25 are fixedly connected to the side plate 2 and the bottom plate 1. A control box 26 containing a battery is provided between the two reinforcing plates 25. The control box 26 is fixedly connected to the bottom plate 1. The reinforcing plates 25 improve the stability of the connection between the side plate 2 and the bottom plate 1. The battery can not only provide power to the device, but can also be connected to the power source through wires, increasing the flexibility of the device.

[0031] like Figure 1 and Figure 5 As shown, the bottom four corners of the base plate 1 are fixedly connected with universal wheels 27 with braking function, and the top side of the base plate 1 is fixedly connected with a push rod 28. The push rod 28 cooperates with the universal wheels 27 to facilitate the user to move and fix the device.

[0032] like Figure 1 As shown, both sides of the cement box 4 are fixedly connected to a fixing plate 29. On the side of the fixing plate 29 away from the cement box 4, there are two structural plates 30. The structural plates 30 are fixedly connected to the fixing plate 29 and the mold frame 6, which improves the structural strength of the connection between the cement box 4 and the mold frame 6.

[0033] Working principle: The worker pours concrete into the cement box 4, then starts the third motor 22. The output of the third motor 22 drives the screw 21. As the screw 21 rotates, it controls the lifting block 20 to move downward. The lifting block 20 moves downward through the sliding rod 24, simultaneously driving the connecting frame 23. The connecting frame 23 drives the cement box 4. As the cement box 4 moves downward, it drives the mold frame 6 through the discharge port 5, thus lowering the mold frame 6 to the ground. The worker can adjust the height of the mold frame 6 according to the road conditions, thereby adjusting the angle and height of the crash barrier, improving the practicality of the device. Then, the second motor 19 is started. The output of the second motor 19 drives the rotating shaft 18, which drives the second bevel gear 17. The second bevel gear 17 drives the first bevel gear 16 to rotate. As the first bevel gear 16 rotates, it drives the hollow tube 10. While rotating, the mixing rod 15 is driven to continuously stir the concrete inside the cement box 4, thereby extending the concrete's setting time. When it is necessary to pour the crash barrier, the first motor 13 is started. The output end of the first motor 13 drives the transmission shaft 11, which in turn drives the auger blades 14. As the auger blades 14 rotate, they transport the concrete inside the cement box 4 through the discharge port 5 to the inside of the mold frame 6, thus achieving the purpose of pouring the crash barrier. This automatic pouring of the crash barrier reduces the workload of workers and improves work efficiency. It solves the problem that although the existing bridge crash barrier construction device can fix templates of different sizes, it does not have the function of pouring concrete into the inside of the template. This results in workers having to manually pour concrete into the mold after fixing the template, which increases the workload of workers and leads to poor work efficiency.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
