Description

Technical Field

[0001] This utility model relates to the field of power engineering construction technology, and in particular to a ground anchor removal device for power engineering construction. Background Technology

[0002] In power engineering construction, ground anchors are key anchoring devices used to fix temporary or permanent facilities. By transferring the load to the soil or rock, they ensure the stability of power equipment and prevent equipment displacement or overturning due to external forces. These include pile-type ground anchors and spiral ground anchors.

[0003] The ground anchor is still removed by force pulling out, which requires a certain amount of motor power. After being forcibly pulled out to a certain depth, there is a risk that the ground anchor will pop out. Its safety and overall efficiency are low. It requires power from motors and other equipment, resulting in a large overall weight of the equipment, making it inconvenient to carry and transport. Its use is also limited by power supply scenarios, and the cost is high.

[0004] An existing patent (publication number: CN221941336U) discloses a ground anchor removal device. This utility model uses a movable plate and a half gear to drive a connecting plate and a hollow hammer to move. The hollow hammer moves in an arc around the hinge point between the connecting plate and the mounting shell, causing it to strike the ground anchor connected to the hook. While the ground anchor is loosened, the device also vibrates the hook and the lifting shaft, causing the lifting shaft to change position. This simulates the method of manually striking and removing the ground anchor, and completes the removal of the ground anchor at the same time as the striking. This improves the removal efficiency and eliminates safety hazards.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, the fixing plates proposed in these patents require downward pressure to overcome the spring force during use, and the hooks must be hung on the surface of the ground anchor, making the operation inconvenient. Furthermore, the removal process requires repeatedly pulling the movable plate, consuming a significant amount of labor. Additionally, the hollow hammer can easily scatter dry soil during the hammering process, affecting the normal operation of workers and impacting the efficiency of ground anchor removal in power engineering construction.

[0006] Therefore, a device for removing ground anchors used in power engineering construction is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a ground anchor removal device for power engineering construction, which can solve the problems proposed in the existing patent. When using the fixing plate, it is necessary to press down to overcome the elastic force of the spring, and at the same time, the hook needs to be hung on the surface of the ground anchor, which is inconvenient to operate. In addition, the removal process requires repeated pulling of the movable plate, which consumes a lot of labor. Furthermore, during the hollow hammer strike, dry soil clods are easily splashed, which affects the normal operation of the workers and reduces the efficiency of ground anchor removal in power engineering construction.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a ground anchor removal device for power engineering construction, including a fixed frame, with support plates fixedly connected to both sides of the bottom of the fixed frame, a pulling mechanism provided on the rear side of the fixed frame, and a protective mechanism provided inside the fixed frame;

[0009] The pulling mechanism includes a connecting plate, a fixed column, an electric telescopic rod, and a hook. The bottom of the connecting plate is fixedly connected to the top of the fixed column, the bottom of the fixed column is fixedly connected to the top of the telescopic end of the electric telescopic rod, the top of the connecting column is fixedly connected to the bottom of the connecting plate, and the top of the hook is fixedly connected to the bottom of the connecting column.

[0010] Preferably, the protective mechanism includes two connecting blocks, a protective cover, and an opening. The side of the connecting block closest to the protective cover is fixedly connected to the protective cover, and the side of the connecting block closest to the support plate is fixedly connected to the surface of the support plate. The opening is located inside the protective cover.

[0011] Preferably, the protective cover is made of magnesium alloy.

[0012] Preferably, a support plate is fixedly connected between the two support plates on opposite sides, and the bottom of the electric telescopic rod is fixedly connected to the top of the support plate.

[0013] Preferably, a support rod is fixedly connected to the bottom of the connecting plate, the rear side of the support rod is fixedly connected to the front side of the fixing column, a through hole is opened inside the fixing frame, and the connecting column is movably disposed inside the through hole.

[0014] Preferably, a rubber block is fixedly connected to the top of the support plate, and the number of rubber blocks is several and they are evenly distributed on the top of the support plate.

[0015] Preferably, a polypropylene insulating pad is fixedly connected to the bottom of both the support plate and the bottom of the bracing plate, and a raised cone is fixedly connected to the bottom of the polypropylene insulating pad. The number of raised cones is several and they are evenly distributed on the bottom of the polypropylene insulating pad.

[0016] Preferably, the top of the fixing frame is provided with sliding holes on the front and rear sides, and the top of the fixing frame is provided with handles on both sides. The handles are slidably connected inside the sliding holes, and the rear side of the support plate is fixedly connected with a handle.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application, by setting up a pulling mechanism, can control the extension end of the electric telescopic rod to extend upward through an external power supply and an external controller, and pull out the pile-type ground anchor by applying upward force through the hook, saving physical strength. The device is compact and easy to move. It solves the problem that the fixing plate proposed in the existing patent needs to be pressed down to overcome the elastic force of the spring when in use, and the hook needs to be hung on the surface of the ground anchor at the same time, which is inconvenient to operate. In addition, the removal process requires repeated pulling of the movable plate, which consumes a lot of labor.

[0019] 2. This application incorporates a protective mechanism. The ground anchor enters the protective cover through an opening and is attached to a hook. The protective cover can then block the dry soil clods that splash out when the ground anchor is pulled out, thus preventing interference with the normal operation of the workers.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] A device for removing ground anchors used in power engineering construction includes a fixed frame 1, with support plates 6 fixedly connected to both sides of the bottom of the fixed frame 1, a pulling mechanism 3 provided on the rear side of the fixed frame 1, and a protective mechanism 8 provided inside the fixed frame 1.

[0030] The pulling mechanism 3 includes a connecting plate 301, a fixed column 302, an electric telescopic rod 303, a connecting column 304, and a hook 305. The bottom of the connecting plate 301 is fixedly connected to the top of the fixed column 302, the bottom of the fixed column 302 is fixedly connected to the top of the telescopic end of the electric telescopic rod 303, the top of the connecting column 304 is fixedly connected to the bottom of the connecting plate 301, and the top of the hook 305 is fixedly connected to the bottom of the connecting column 304.

[0031] In this embodiment: When removing ground anchors used in power engineering construction, the operator uses the handle 4 to move the fixing frame 1 above the ground anchor to be removed. The hook 305 is attached to the force-bearing ring at the top of the ground anchor. The operator steps on the rubber block 5 at the top of the support plate 6. Its elastic surface increases friction and disperses the stepping force to ensure the stability of the fixing frame 1. The protruding cone 9 at the bottom of the polypropylene insulating pad 7 penetrates the soil, enhancing the grip, preventing slippage, and isolating the risk of leakage. After confirming that the attachment is stable, the external controller starts the electric telescopic rod 303 powered by the external power supply. Its telescopic end drives the fixing column 302, connecting plate 301, and connecting column 304 to move upward. The ground anchor is lifted through the hook 305. During the lifting, the magnesium alloy protective cover 802 prevents mud from splashing and injuring people. The electric telescopic pole 303 provides stable upward traction, replacing manual prying and reducing physical exertion. Multiple design features enhance construction safety. It solves the problems of existing patents where the fixing plate requires downward pressure to overcome the spring force, and the hook must be attached to the anchor surface, making operation inconvenient. Furthermore, the removal process requires repeated pulling of the movable plate, consuming significant labor, and the hollow hammer can easily scatter dry soil, affecting workers' operations and impacting the efficiency of anchor removal in power engineering construction. It should be noted that the hook 305 pulls out smooth-surfaced pile anchors, allowing direct upward force without damaging them.

[0032] Specifically, such as Figure 2 and Figure 4 As shown, the protective mechanism 8 includes two connecting blocks 801, a protective cover 802 and an opening 803. The side of the connecting block 801 near the protective cover 802 is fixedly connected to the protective cover 802, and the side of the connecting block 801 near the support plate 6 is fixedly connected to the surface of the support plate 6. The opening 803 is opened inside the protective cover 802.

[0033] Specifically, such as Figure 4 As shown, the protective cover 802 is made of magnesium alloy.

[0034] Specifically, such as Figure 2 As shown, a support plate 10 is fixedly connected between the two support plates 6 on opposite sides, and the bottom of the electric telescopic rod 303 is fixedly connected to the top of the support plate 10.

[0035] In this embodiment: by covering the contact area between the ground anchor and the ground with the protective cover 802, it is possible to prevent dry soil clods from splashing out and injuring people during the process of pulling out the ground anchor. The protective cover 802, made of magnesium alloy, is strong and lightweight. The bottom of the electric telescopic rod 303 is fixedly connected to the top of the support plate 10, so that the support plate 10 can stably support the electric telescopic rod 303.

[0036] Specifically, such as Figure 3 As shown, a support rod 11 is fixedly connected to the bottom of the connecting plate 301. The rear side of the support rod 11 is fixedly connected to the front side of the fixing column 302. A through hole 13 is opened inside the fixing frame 1, and the connecting column 304 is movably disposed inside the through hole 13.

[0037] Specifically, such as Figure 2 As shown, a rubber block 5 is fixedly connected to the top of the support plate 6. There are several rubber blocks 5, which are evenly distributed on the top of the support plate 6.

[0038] In this embodiment: the strut 11 connects the connecting plate 301 and the fixed column 302 to form a triangular support structure, which enhances the stability of the connecting plate 301 and prevents the connecting plate 301 from bending due to excessive tension. The rubber block 5 makes it more stable for workers to step on the support plate 6, thereby maintaining the stability of the fixed frame 1 and allowing the ground anchor to be pulled upward stably.

[0039] Specifically, such as Figure 2 and Figure 6 As shown, a polypropylene insulating pad 7 is fixedly connected to the bottom of the support plate 6 and the bottom of the support plate 10. A raised cone 9 is fixedly connected to the bottom of the polypropylene insulating pad 7. There are several raised cones 9, which are evenly distributed on the bottom of the polypropylene insulating pad 7.

[0040] Specifically, such as Figure 5 As shown, sliding holes 12 are provided on the front and rear sides of the top of the fixed frame 1, and handles 2 are provided on both sides of the top of the fixed frame 1. The handles 2 are slidably connected inside the sliding holes 12, and a handle 4 is fixedly connected to the rear side of the support plate 10.

[0041] In this embodiment: the raised cone 9 at the bottom of the polypropylene insulating pad 7 penetrates the ground soil, further enhancing the grip between the device and the ground. Even on wet or loose ground, the cone-shaped structure of the raised cone 9 can effectively prevent the device from sliding. Through the insulating properties of the insulating pad, it can also isolate the risk of leakage from the ground. The fixed frame 1 can be moved between multiple ground anchors by holding the handle 2. When the handle 2 is released, the handle 2 will fall down for easy storage. Holding the handle 4 makes it easy to move the entire device over long distances.

[0042] Working Principle: When removing ground anchors used in power engineering construction, first, holding handle 4, move the fixing frame 1 above the ground anchor to be removed, aligning the hook 305 with the anchor's force ring and securing it firmly. The operator then steps on the rubber blocks 5 on top of the support plate 6 with both feet. The elastic surface of the rubber blocks 5 increases the friction between the feet and the support plate 6, and the even distribution of multiple rubber blocks 5 disperses the stepping force, ensuring the fixing frame 1 remains stable and does not wobble. At this time, the raised cone 9 at the bottom of the polypropylene insulating pad 7 penetrates the ground soil, further enhancing the grip between the device and the ground. Even on wet or loose ground, the conical structure of the raised cone 9 effectively prevents the device from sliding. The insulating properties of the insulating pad further enhance this effect. It can also isolate the risk of potential ground leakage, ensuring the safety of operators. After confirming that the hook 305 is correctly attached and the device is stable, the electric telescopic rod 303 is started through the external controller. The electric telescopic rod 303 is powered by an external power source. The telescopic end of the electric telescopic rod 303 drives the fixed column 302 and the connecting plate 301 to move upward slowly. The connecting column 304 moves upward synchronously in the through hole 13, and then applies an upward pulling force to the ground anchor through the hook 305. During the lifting process, the dry mud around the ground anchor may be loosened due to the force and splash. At this time, the protective cover 802 of the protective mechanism 8 plays a role. The magnesium alloy protective cover 802 is strong and lightweight, and the opening 803 makes it easy to... The anchor moves inside the protective cover 802, effectively preventing mud from splashing outwards and causing injury. Simultaneously, the support rod 11 connects the connecting plate 301 and the fixed column 302, forming a triangular support structure that enhances the stability of the connecting plate 301 and prevents it from bending due to excessive tension. As the electric telescopic rod 303 continues to pull upwards, the ground anchor is gradually pulled out of the soil. The handle 2 slides inside the sliding hole 12, allowing for easy movement of the fixed frame 1 between multiple ground anchors. Releasing the handle 2 causes it to fall down for easy storage. Throughout the dismantling process, the electric telescopic rod 303 provides stable traction, replacing traditional manual prying and significantly reducing costs. The device reduces the physical exertion of operators and significantly improves construction safety through multiple designs including protection, insulation, and anti-slip features. It solves the problems of existing patents where the fixing plate needs to be pressed down to overcome the spring force while the hook is attached to the ground anchor surface, making operation inconvenient. Furthermore, the removal process requires repeated pulling of the movable plate, consuming a lot of labor, and dry soil clods are easily splashed during the hollow hammer strike, affecting the normal operation of workers and the efficiency of ground anchor removal in power engineering construction. It should be noted that the ground anchor pulled up by hook 305 is a smooth-surfaced pile anchor, which can be pulled out directly by applying upward force without damaging the ground anchor.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
