Description

Technical Field

[0001] The invention relates to a ground pile lifting device, belonging to the technical field of radar auxiliary tools. Background Art

[0002] Radar antenna vehicles operating in high winds must maintain stable sway to ensure accurate measurement. Due to the limited weight of the vehicle itself, which is often insufficient to withstand external wind loads, ground stakes and wire ropes are often used to increase the vehicle's wind resistance and prevent sway or tipping. When relocating a vehicle, the stakes must be quickly removed. Traditionally, these removal methods involve hammering them manually or pulling them out with a crane or forklift. Manually removing the stakes requires repeated hammering around the perimeter to loosen them before extraction, which is extremely time-consuming and labor-intensive. Furthermore, the stakes cannot be driven vertically into the ground to withstand force. While cranes or forklifts are relatively easy to remove, they can only be pulled vertically upwards, which can easily damage the stakes. Furthermore, renting a crane or forklift in the field is not always possible. Removing these small stakes is crucial to the proper functioning and rapid relocation of the vehicle-mounted radar. Therefore, developing a tool-free extraction device is crucial for smooth stake removal. Summary of the Invention

[0003] The object of the present invention is to address the deficiencies of the above-mentioned prior art and to provide a ground pile extraction device that is suitable for extracting ground piles at different angles, is simple to manufacture, is easy to extract, saves time and effort, does not damage the ground piles, and is easy to carry; so as to solve the problems that the existing manual extraction of ground piles is time-consuming and labor-intensive, and that cranes or forklifts can only extract ground piles vertically with great force, which may easily cause damage to the ground piles.

[0004] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0005] A ground pile extraction device comprises a support, a connecting rod, a plurality of friction blocks, a pressing block, a handle and a plurality of pins; its characteristics are as follows: the support is equipped with a connecting rod via a pin, and the connecting rod rotates around the pin to change the angle of the ground pile extraction; the front end of the pressing block is made with a support ear, and the pressing block is connected to the connecting rod via the support ear and the pin, and the handle is mounted on the tail of the pressing block via a thread, and the handle can be removed after the work is completed; the pressing block rotates relatively around the center of the pin to drive the handle to move up and down; the connecting rod and the pressing block are respectively equipped with friction blocks, and when working, the friction blocks are tightly connected to the ground pile.

[0006] The support is composed of a bottom block, a warp, a mounting seat, and a pin shaft hole a. The bottom block is made into a large flat surface, and warps are made on both sides of the large flat surface of the bottom block to increase the support area, disperse the contact stress, and facilitate the sliding movement of the support relative to the ground pile when it is subjected to force; a mounting seat is made symmetrically in the front and back of the center of the bottom block, and a pin shaft hole a is made on the mounting seat.

[0007] The connecting rod is rectangular, and a pin hole a is also made through the lower part of the front side of the connecting rod. The connecting rod is connected to the mounting seat through the pin hole a and the pin; a pin hole b is made through the middle part of the front side of the connecting rod, and friction blocks are symmetrically installed on the right side of the connecting rod. The contact surface between the friction block and the ground pile is made into a horizontal and vertical cross serrated shape to increase friction.

[0008] The top of the clamping block is made with a support ear, and the support ear is also made with a pin shaft hole b. The clamping block is installed on the connecting rod through the pin shaft hole b and the pin shaft; a friction block is also symmetrically installed on the left side of the clamping block. The installation position of the friction block corresponds to the installation position of the friction block on the connecting rod. When working, they hold the ground pile in opposite directions. The contact surface between the friction block and the ground pile is also made into a horizontal and vertical cross serrated shape to increase friction.

[0009] The beneficial effects of the present invention compared with the prior art are:

[0010] The support of the pile extraction device changes the angle of the pile extraction by rotating the connecting rod around the pin, which can adapt to the different extraction angles of the pile. The interaction between the handle, connecting rod and clamping block causes the friction block to clamp the pile and generate a large friction force. The handle is operated by the lever principle to move continuously. The pile is first pulled out a certain distance, and then the entire pile can be pulled out by gently shaking the handle left and right. When the work is completed, the thread is loosened and the handle is removed, making it convenient to carry the pile extraction device. The pile extraction device of the present invention is suitable for extracting piles at different angles. It is simple to manufacture, easy to extract, and saves time and effort. The extraction process does not damage the pile. It perfectly solves the problem that the existing manual extraction of piles is time-consuming and labor-intensive, and the crane or forklift can only extract the pile vertically with great force, which can easily damage the pile. It has achieved very good results in actual use. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention is based on the following principles: Ground piles 7 are widely used in the field deployment of current vehicle-mounted radars. Although relatively small, they are crucial to ensuring the proper functioning of radar antennas in harsh weather conditions. In practice, removing ground piles 7 is a significant task, especially during periods of heavy rain and wind. Removal typically involves manually hammering the piles 7 or using a crane or forklift to pull them out, a time-consuming and labor-intensive process. While renting a crane or forklift can significantly ease the process, the mechanical pulling of cranes and forklifts can easily damage the piles 7, a common occurrence in actual removal. Furthermore, renting cranes and forklifts is often difficult in remote areas, making the removal of ground piles 7 extremely inconvenient. Therefore, the present invention utilizes the principle of leverage to design a ground pile 7 extraction device. This device features a simple structure, is easy to manufacture, assemble, and use, and offers excellent performance, effectively resolving the aforementioned issues. The operator simply needs to repeatedly shake the handle 5 up and down to remove the pile 7, resulting in a simple, time-saving, and labor-saving operation. The handle 5 is detachable and portable, making it highly desirable for users.

[0018] The specific implementation of the pile extraction device is further described in detail below with reference to the accompanying drawings:

[0019] A ground pile extraction device comprises a support 1, a connecting rod 2, a plurality of friction blocks 3, a pressing block 4, a handle 5 and a plurality of pins 6; its characteristics are as follows: the support 1 is mounted with a connecting rod 2 via a pin 6, and the connecting rod 2 rotates around the pin 6 to change the angle of the ground pile 7; the front end of the pressing block 4 is made with a support ear 13, and the pressing block 4 is connected to the connecting rod 2 via the support ear 13 and the pin 6, and the handle 5 is attached to the tail of the pressing block 4 by a thread. After work, the handle 5 is detachable and easy to carry; the pressing block 4 rotates relative to the center of the pin 6, driving the handle 5 to move up and down; the connecting rod 2 and the pressing block 4 are respectively mounted with friction blocks 3. When working, the friction blocks 3 are tightly connected to the ground pile 7 (see Figures 1 to 5 ).

[0020] In order to describe the corresponding installation positions of the pin holes on the support 1 and the connecting rod 2 and the connecting rod 2 and the pressing block 4, the pin holes are separately described as the pin hole a11 and the pin hole b12.

[0021] The support 1 is composed of a bottom block 8, a tilting 9, a mounting seat 10, and a pin hole a11. The bottom block 8 is made into a large plane, and tilting 9 is made on both sides of the large plane of the bottom block 8 to increase the support area and disperse the contact stress, so as to facilitate the sliding movement of the support 1 relative to the pile 7 when the force is applied; a mounting seat 10 is made symmetrically in the middle of the bottom block 8, and a pin hole a11 is made on the mounting seat 10 (see Figure 2 ).

[0022] The connecting rod 2 is a rectangular body, and a pin hole a11 is also made through the lower part of the front side of the connecting rod 2. The connecting rod 2 is connected to the mounting seat 10 through the pin hole a11 and the pin 6; a pin hole b12 is made through the middle part of the front side of the connecting rod 2, and friction blocks 3 are symmetrically installed on the right side of the connecting rod 2. The contact surface of the friction block 3 and the ground pile is made into a horizontal and vertical cross serrated shape to increase friction (see Figure 3 ).

[0023] The top of the pressing block 4 is made with a support ear 13, and the support ear 13 is also made with a pin shaft hole b12. The pressing block 4 is installed on the connecting rod 2 through the pin shaft hole b12 and the pin shaft 6; the left side of the pressing block 4 is also symmetrically installed with a friction block 3. The installation position of the friction block 3 corresponds to the installation position of the friction block 3 on the connecting rod 2. When working, they hold the ground pile 7 in opposite directions. The contact surface of the friction block 3 and the ground pile is also made into a horizontal and vertical cross serrated shape to increase friction (see Figure 4 、 Figure 5 ).

[0024] The pile extraction device has the following features:

[0025] The bottom block 8 of the support 1 is a large flat surface, which increases the support area, disperses the contact stress during operation, and avoids the ground from being compressed when the ground is soft; the two sides of the bottom block 8 are designed with tilting 9 to facilitate the operation of the handle 5 to make the support 1 slide relative to the ground pile 7 when the force is applied; the friction blocks 3 on the connecting rod 2 are symmetrically arranged to meet the extraction operation of the ground pile 7 in both the front and rear directions; the contact surfaces of the friction blocks 3 installed on the connecting rod 2 and the friction blocks 3 installed on the clamping block 4 with the ground pile 7 are designed with horizontal and vertical cross serrations to increase friction, so that the ground pile 7 is tightly held during operation, and the ground pile 7 is extracted by the lever force of the handle 5; the clamping block 4 is connected to the connecting rod 2 by a pin 6 through the support ear 13 provided at its front end, so that the clamping block 4 rotates around the pin 6, which facilitates the lever movement of the handle 5 connected thereto; the positions of the two friction blocks 3 provided on both sides of the upper part of the clamping block 4 correspond to the positions of the friction blocks 3 on the connecting rod 2; the handle 5 is installed at the tail of the clamping block 4 through a threaded connection, so that the handle 5 is detachable and easy to carry and transport.

[0026] The working principle of the pile extraction device is as follows:

[0027] (See Figures 1 to 5), when pulling out the ground pile 7, the operator pulls up the handle 5, and the handle 5 drives the pressing block 4 to rotate counterclockwise around the pin shaft hole b12 on the connecting rod 2, and the friction block 3 installed on the pressing block 4 and the friction block 3 installed on the connecting rod 2 clamp the ground pile 7. At this time, the handle 5, the pressing block 4, the connecting rod 2, the friction block 3 and the ground pile 7 constitute a pulling whole. When the handle 5 continues to rotate counterclockwise, the pulling whole will rotate counterclockwise around the pin shaft hole b12 on the support 1. The distance between the ground pile 7 and the pin shaft hole b12 of the support 1 is relatively close, and the far end of the handle 5 is relatively far from the pin shaft hole b12 of the support 1, thus forming a lever amplification effect. The pulling whole pulls out the ground pile 7 a short distance along its embedded angle, and then the entire ground pile 7 can be easily taken out by shaking the handle 5 up and down. This ground pile 7 extraction device achieves the extraction operation of ground piles 7 at different angles by rotating the connecting rod 2 connected to the support 1. When the handle 5 moves upward, the connecting rod 2 and the pressing block 4 interact, causing the friction block 3 to clamp the ground pile 7 and generate a large friction force. Using the principle of leverage, the handle 5 continues to move upward to extract the ground pile 7 a certain distance. Repeatedly shaking the handle 5 up and down can extract the entire ground pile 7. This effectively solves the problems of manual extraction of ground piles 7, which is time-consuming and labor-intensive, and the use of cranes or forklifts to extract ground piles 7, which can easily cause damage to the ground piles 7.
