Description

Technical Field

[0001] This utility model relates to a safety device for transporting pipe pile end plates. Background Technology

[0002] Pipe piles are a type of building material, generally used as foundation material driven into the ground. They transfer the weight of the superstructure to the lower, more load-bearing soil layer and improve the bearing capacity of the foundation soil. They are widely used in large-scale engineering projects such as railways, highways, bridges, and ports. Modern pipe piles typically use prestressed high-strength concrete pipe piles (PHC pipe piles), which offer advantages such as short construction cycles and stable quality. The pipe piles have end plates at both ends; for details, please refer to Chinese Patent CN202223046904.7.

[0003] In manufacturing enterprises, when the pipe pile end plates are moved from the production station to the usage station, they are generally first stacked in a staggered manner on a flat plate and then transported by crane. The stacking method is described in [reference needed]. Figures 1-3 , Figure 1 The bottom layer typically consists of six pipe pile end plates arranged tightly in two rows and three columns. The second layer uses... Figure 2 The method involves first placing two pipe pile end plates 1 in each row, staggered from the three pipe pile end plates 1 in each row of the first layer. The remaining two pipe pile end plates 1 are then placed at the left and right ends, tangent to the corresponding two pipe pile end plates 1 on the left or right side, respectively. (See [reference]). Figure 3 Then the third layer replicates the arrangement of the first layer, and so on, with the top layer generally following the same pattern. Figure 2 To prevent the top six pipe pile end plates 1 from being unstable and collapsing due to instability, which could cause an engineering accident, the existing technology involves binding the top six pipe pile end plates 1 with wire. This forms a single unit, using its own weight to hold down all the pipe pile end plates 1 below. Because of the pre-binding, it is less likely to scatter and collapse. Once bound, it can be hoisted. However, this method has drawbacks. Binding the wire takes time, even for skilled operators, and requires disassembly during use, severely impacting efficiency. Furthermore, the wire is prone to loss and excessive wear due to repeated bending. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a safety device for transporting pipe pile end plates. The device has a simple structure and is easy to use. Compared with the existing method of binding with iron wire, it effectively improves efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides a safety device for transporting pipe pile end plates, including a horizontally arranged main rod with its length direction running left to right. The main rod has six elongated movable parts, labeled as the first movable part, second movable part, third movable part, fourth movable part, fifth movable part, and sixth movable part. Each movable part includes a horizontally arranged cylindrical body. Each cylindrical body has one end closed and the other end open along its length. Each open end of the cylindrical body has a movable rod arranged coaxially with the corresponding cylindrical body. One end of each movable rod is located inside the corresponding cylindrical body, and the other end extends out of the cylindrical body. Each movable rod slides along the axial direction of the corresponding cylindrical body's inner cavity. The movable rod is positioned with its length direction within the corresponding cylindrical body. The inner end is called the inner end, and the outer end is called the outer end. Each movable rod has a spring arranged coaxially with the movable rod and cooperating with the inner cavity of the corresponding cylinder between the inner end of the movable rod and the corresponding cylinder sealing end. Each movable rod has an extension rod extending vertically downward at the outer end. Each movable part is connected to the main rod from the corresponding cylinder sealing end. The first and second movable parts run left and right along their length direction and are connected to the left and right end faces of the main rod respectively. The third and fourth movable parts run front and back along their length direction and are connected to the front of the main rod near the left and right ends of the main rod respectively. The fifth and sixth movable parts are located on the rear side of the main rod and are directly opposite the third and fourth movable parts along the front and back directions respectively.

[0006] For the sake of simplicity, the pipe pile end plate transportation safety device described in this utility model will be referred to as "this device" in the following text.

[0007] How to use this device and its advantages:

[0008] After the top six pipe pile end plates are stacked, place this device horizontally above them, ensuring that each of the six movable parts of the device corresponds to one of the six end plates. Then, pull the movable rod outwards so that the extension rod of each movable part engages with the central hole of the corresponding end plate. Finally, press down on the main body of the device so that the entire side wall of each extension rod is tightly against the central hole wall of the corresponding end plate. Due to the spring's restoring force, the top six end plates tend to contract inwards, preventing them from scattering and ensuring the stability of stacking and the safety of transportation. Furthermore, this device has a simple structure and is easy to use. Compared to existing methods of binding with wire, it effectively improves efficiency while ensuring safety.

[0009] To achieve better performance from this device, the preferred solution is as follows:

[0010] Preferably, the extension rod is covered with an anti-slip rubber layer on its outer axial side.

[0011] The anti-slip rubber layer increases friction, allowing the extension rod to fit more tightly against the central hole wall of the corresponding pipe pile end plate, effectively reducing unnecessary slippage. In addition, the anti-slip rubber layer also acts as a buffer, preventing unnecessary wear between the extension rod and the central hole wall of the pipe pile end plate due to spring compression.
