Description

Technical Field

[0001] This utility model belongs to the field of lightning protection and grounding technology, and specifically relates to a portable lightweight pile extractor. Background Technology

[0002] When mobile weapons and equipment such as radar, missiles, communications command and control, and electronic warfare equipment, as well as their supporting mobile lightning protection equipment, are working in the field, multiple grounding stakes need to be driven in quickly to achieve the grounding function. The driving depth of the grounding stakes is usually required to reach about 1 meter.

[0003] However, the soil geology and topography in the field are complex and diverse. After the grounding pile is driven in, it will be tightly bonded to the soil, making it difficult to pull out when the grounding grid needs to be changed after use. Traditional pile pulling operations are not only inefficient, but also require a lot of manpower and are slow.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is a portable lightweight pile extractor, including a pile extractor body and an operating frame. Multiple pile extractor hooks are vertically arranged on the pile extractor body. A first connection hole is opened on the operating frame, and a first connecting pin passes through the first connection hole. The first connecting pin is placed on the pile extractor hook. A second connection hole is opened at the end of the operating frame, and a second connecting pin passes through the second connection hole. A pile extractor support plate is rotatably installed on the second connecting pin.

[0006] There is at least one set of connection holes.

[0007] A force-applying rod is installed at the end of the operating frame away from connection hole two.

[0008] The pile extraction support plate has a pile extraction slot.

[0009] The connecting pin and the connecting hole are detachable.

[0010] The connecting pin two and the connecting hole two are detachable.

[0011] The surface of the force-applying rod is fitted with an anti-slip sleeve.

[0012] This utility model has the following beneficial effects: 1. This utility model utilizes the pile-pulling hook as a stable fulcrum, and the operating frame forms a basic lever structure. The force-applying rod at the end of the operating frame further extends the power arm, transforming human power into a highly efficient upward pile-pulling force, replacing the traditional direct dragging by human power, greatly reducing labor intensity and improving pile-pulling efficiency.

[0013] 2. This utility model utilizes a single connection hole with multiple sets, which can flexibly adjust the fulcrum position according to the burial depth of the grounding pile and the hardness of the soil, further optimizing the lever arm ratio. Even when facing grounding piles that are tightly bonded in hard soil in the field, it can quickly generate sufficient traction force to pull them out, effectively meeting the needs of mobile weapon equipment for rapid pile removal in the field.

[0014] 3. This utility model achieves rapid disassembly and assembly of the pile extraction body and the operating frame through the detachable connection of connecting pin one and connecting hole one, and connecting pin two and connecting hole two. After the pile extraction is completed, only two sets of connecting pins need to be pulled out to separate the pile extraction body, operating frame, pile extraction support plate and other components. The disassembled components are small in size and lightweight, and can be stored without additional tools, greatly reducing storage space. It perfectly fits the design positioning of "portable and lightweight" and solves the pain point that traditional large pile extraction equipment is difficult to adapt to field mobile operations.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-3 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0019] Please see Figures 1-3 As shown: This embodiment provides a portable lightweight pile extractor, including a pile extractor body 1 and an operating frame 2. The pile extractor body 1 is vertically provided with multiple pile extractor hooks 3. The operating frame 2 has a first connection hole 4, through which a first connecting pin 5 passes. The first connecting pin 5 is attached to the pile extractor hooks 3. The end of the operating frame 2 has a second connection hole 6, through which a second connecting pin 7 passes. A pile extractor plate 8 is rotatably installed on the second connecting pin 7. The pile extractor plate 8 has a pile extractor slot 10, which is engaged with the grounding pile through the pile extractor slot 10.

[0020] In use, the main body 1 of the pile extraction device is placed vertically on the ground near the grounding pile. The pile extraction plate 8 is connected and fastened to the extraction end of the grounding pile to be extracted through the pile extraction slot 10. Then, the operating frame 2 with the connecting pin 1 inserted is placed on the pile extraction hook 3 on the main body 1 of the pile extraction device. The pile extraction hook 3 becomes the fulcrum of the lever. When the operator presses down on the operating frame 2, based on the lever principle, the operating frame 2 will generate an upward traction force with the pile extraction hook 3 as the fulcrum. This force is transmitted to the pile extraction plate 8 through the connecting pin 2 7, and then the grounding pile that is fastened to it is lifted vertically upward through the pile extraction slot 10. This device converts human power into a highly efficient upward pile extraction force through the lever principle, replacing the traditional direct dragging by human power, greatly reducing labor intensity and improving pile extraction efficiency. The design of multiple pile-pulling hooks 3 can adapt to grounding piles of different heights, thus improving the applicable scenarios.

[0021] like Figure 1-2 As shown, there is at least one set of connecting holes 4 (which can be designed as multiple sets distributed vertically or horizontally). When facing grounding piles of different lengths and diameters, or complex geological conditions in the field (such as hard soil or differences in the burial depth of grounding piles), connecting pins 5 can be installed in connecting holes 4 at different positions and placed on the pile pulling hook 3. By adjusting the installation position of the connecting pins 5, the lever arm length of the operating frame 2 can be changed. When a greater pile pulling force is required, connecting holes 4 further away from the pile pulling plate 8 can be selected to extend the power arm and amplify the traction force. When the grounding pile is easier to pull out, connecting holes 4 closer to the pile pulling plate 8 can be selected to improve operational flexibility and adapt to diverse pile pulling scenarios.

[0022] like Figure 1-2 As shown, the end of the operating frame 2 away from the connection hole 2 6 is equipped with a force-applying rod 9. The length of the power arm has been extended based on the original lever structure, which greatly reduces the labor cost required for pile extraction. The surface of the force-applying rod 9 is fitted with an anti-slip sleeve to increase the friction between the hand and the force-applying rod 9 and improve the stability of operation.

[0023] like Figure 1-2As shown, the connecting pin 1 5 and connecting hole 1 4 are detachable, and the connecting pin 2 7 and connecting hole 2 6 are detachable, which facilitates the disassembly, carrying and assembly of the equipment, meeting the design requirements of "portable and lightweight". After the pile is pulled out, the connecting pins can be quickly disassembled to separate the pile pulling body 1 from the operating frame 2, reducing storage space.

[0024] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
