Description

Technical Field

[0001] This utility model belongs to the field of municipal engineering technology, specifically relating to a suspension protection device for concrete culverts. Background Technology

[0002] Existing urban drainage systems typically use concrete culverts as drainage pipes. During the excavation and construction of municipal engineering projects, existing concrete culverts need to be hoisted and protected using suspension devices. Traditional methods for hoisting and protecting concrete culverts usually involve binding them with steel wire ropes. Before protection, the steel wire ropes are wrapped around the concrete culvert for protection. This method is inconvenient to construct, and during long-term hoisting and protection, the steel wire ropes may slip, causing the stress point to change, resulting in poor protection of the culvert and even safety accidents.

[0003] Currently, the construction site uses the clamping arms of concrete culvert lifting tools to hold and protect the culverts during installation. However, the existing culvert lifting tools can only hold culverts of a single diameter and cannot adapt to the needs of culverts of multiple diameters. This results in the need to frequently change different specifications of clamps to accommodate concrete culverts of different diameters during actual construction. This not only increases construction costs but also reduces construction efficiency and causes many inconveniences to on-site operations. In addition, it cannot adapt to concrete culverts of different lengths, and its applicability is poor. Utility Model Content

Detailed Implementation

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Reference Figures 1 to 7 This embodiment proposes a suspended protection device for concrete pipe culverts, including a suspension frame 1. A mounting frame 2 is fixed on the suspension frame 1. Two pairs of clamping arm assemblies 3 are slidably mounted on the side of the suspension frame 1 opposite to the mounting frame 2, enabling the clamping of both ends of the concrete pipe culvert. Furthermore, the suspension frame 1 is also equipped with a screw drive mechanism 4, which can be used to adjust the distance between the two pairs of clamping arm assemblies 3. Specifically, the screw drive mechanism 4 includes a screw 41, a first slider 42, a second slider 43, and a driving member 44. The screw 41 is disposed through the suspension frame 1. The first slider 42 and the second slider 43 are respectively distributed on both sides of the suspension frame 1 and threadedly connected to the screw 41. The driving member 44 is disposed on the... On one side of the suspension frame 1, when the drive member 44 drives the lead screw 41 to rotate, the first slider 42 and the second slider 43 will move closer to or further away from each other. Since the first slider 42 and the second slider 43 are respectively distributed on both sides of the suspension frame 1, the distance between the two pairs of clamping arm assemblies 3 can be flexibly adjusted through this movement method, thereby adapting to concrete culverts of different lengths and greatly improving the applicability of the suspension device. In addition, the suspension frame 1 is also equipped with multiple positioning components 5. The positioning components 5 can be used to position the first slider 42 and the second slider 43 when they move to the appropriate position. During the suspension protection process, the first slider 42 and the second slider 43 can be stably positioned to avoid safety hazards caused by the swaying of the culvert.

[0020] Specifically, the drive component 44 is any one of the drive motors or rotary motors commonly used in the art.

[0021] Specifically, please refer to Figure 2 and Figure 3As shown, the suspension frame 1 has multiple accommodating slots spaced apart along its length, with each positioning component 5 correspondingly disposed in one of these slots. By providing multiple accommodating slots, each containing one positioning component 5, this layout not only makes efficient use of the space in the suspension frame 1 but also ensures a more even distribution of the positioning components 5, thereby enabling more precise positioning of the first slider 42 and the second slider 43. When the first slider 42 and the second slider 43 move under the drive of the lead screw 41, once they reach the preset suitable position, the corresponding positioning component 5 will activate and fix them in place, preventing unnecessary displacement during subsequent suspension protection.

[0022] Specifically, please refer to Figure 3 and Figure 4 As shown, the positioning component 5 includes an elastic element 51 disposed in a receiving groove and a ball 52 connected to the elastic element 51. The elastic element 51 has a certain elastic deformation capability, and can be compressed or stretched when subjected to external force, and return to its original shape after the external force is removed. The ball 52 is connected to the elastic element 51 and can move within a certain range under the action of the elastic element 51. In addition, the first slider 42 and the second slider 43 are provided with positioning holes 45 that engage with the ball 52. When the first slider 42 and the second slider 43 move to a suitable position, the ball 52 will be engaged in the positioning hole 45 under the action of the elastic element 51, achieving precise positioning. In addition, the first slider 42 and the second slider 43 are also provided with an arc-shaped part 46 for guiding the ball 52 to slide out. In this way, when it is necessary to adjust the position of the first slider 42 and the second slider 43, the arc-shaped part 46 can guide the ball 52 to slide out of the positioning hole 45 smoothly, so that the first slider 42 and the second slider 43 can move freely without being obstructed by the positioning component 5.

[0023] Specifically, please refer to Figure 1As shown, the suspension device also includes a first telescopic rod 6, which can be used to connect the mounting frame 2 and the first slider 42. Furthermore, the mounting frame 2 is provided with a first insertion platform 21, and the first slider 42 is provided with a second insertion platform 421. One end of the first telescopic rod 6 is hinged to the first insertion platform 21, and the other end of the first telescopic rod 6 is hinged to the second insertion platform 421. This hinged connection allows the first telescopic rod 6 to rotate flexibly. When the first slider 42 moves, the first telescopic rod 6 can extend, retract, and rotate according to the actual situation, thereby adapting to changes in the distance and angle between the first slider 42 and the mounting frame 2, ensuring the stability of the mounting frame 2. Similarly, the suspension device also includes a second telescopic rod 7 for connecting the mounting frame 2 and the second slider 43. The mounting frame 3 is provided with a third insertion platform 22, and the second slider 43 is provided with a fourth insertion platform 431. One end of the second telescopic rod 7 is hinged to the third insertion platform 22, and the other end is hinged to the fourth insertion platform 431. The second telescopic rod 7 functions similarly to the first telescopic rod 6. Through this design, a stable connection structure is formed between the mounting bracket 2 and the first slider 42 and the second slider 43, further enhancing the stability of the entire suspension device.

[0024] Specifically, please refer to Figure 1 As shown, the top of the mounting frame 2 is equipped with a hook 23. By setting the hook 23, the entire suspension device can be lifted, thereby achieving suspension protection for the concrete culvert.

[0025] Specifically, please refer to Figure 1 As shown, the clamping arm assembly 3 includes a first hinged arm 31 and a second hinged arm 32 connected to the first slider 42 and arranged in a cross pattern. The first hinged arm 31 is provided with a first clamping arm 33, and the second hinged arm 32 is provided with a second clamping arm 34. The first clamping arm 33 and the second clamping arm 34 cooperate to clamp the concrete culvert. In addition, the first clamping arm 33 is provided with a first threaded hole 35, and the second clamping arm 34 is provided with a second threaded hole 36. The clamping arm assembly 3 also includes a bolt, which can pass through the first threaded hole 35 and connect to the second threaded hole 36. The first hinge arm 31 and the second hinge arm 32 are arranged in a cross pattern, which allows the clamping arm assembly 3 to generate a greater clamping force when clamping the concrete culvert, and also to better adapt to concrete culverts of different diameters. The first clamping arm 33 and the second clamping arm 34 cooperate with each other to form a stable clamping space, firmly clamping the concrete culvert. On the other hand, it also makes it easier for construction personnel to adjust the opening angle of the first clamping arm 33 and the second clamping arm 34 according to the different diameters of the culvert, which greatly improves the installation efficiency. By setting multiple bolts and connecting them through the first threaded hole 35 and the second threaded hole 36, the clamping force between the first clamping arm 33 and the second clamping arm 34 is further enhanced, which greatly improves the safety of the suspension protection.

[0026] Specifically, please refer to Figure 1 As shown, the bottom end of the first clamping arm 33 is provided with a first connecting plate 37, and the bottom end of the second clamping arm 34 is provided with a second connecting plate 38. The first threaded hole 35 is formed on the first connecting plate 37, and the second threaded hole 36 is formed on the second connecting plate 38. By setting the first connecting plate 37 and the second connecting plate 38, subsequent bolt through-hole connection is achieved, improving connection efficiency and ensuring clamping stability.

[0027] Specifically, please refer to Figure 7 As shown, the first slider 42 is provided with a connecting platform 47, and the first hinged arm 33 and the second hinged arm 34 are respectively hinged to the connecting platform 47. By setting the connecting platform 47, a stable connection base is provided for the first hinged arm 33 and the second hinged arm 34, allowing them to rotate flexibly on the connecting platform 47, thereby achieving effective clamping of the concrete culvert.

[0028] In actual construction, firstly, based on the length of the concrete culvert, the drive component 44 drives the lead screw 41 to rotate, adjusting the positions of the first slider 42 and the second slider 43, thereby adjusting the distance between the two pairs of clamping arm assemblies 3 to match the length of the concrete culvert. When the first slider 42 and the second slider 43 move to the appropriate position, the positioning component 5 automatically positions itself to ensure the stability of the clamping arm assembly 3. Next, the concrete culvert is placed between the two pairs of clamping arm assemblies, and the clamping arm assemblies 3 are operated to clamp both ends of the concrete culvert, achieving suspension protection for the concrete culvert.

[0029] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
