Description

Technical Field

[0001] This utility model relates to the field of road engineering, specifically a piling device for road engineering. Background Technology

[0002] Piles are a type of foundation with high bearing capacity, wide applicability, and a long history. With the improvement of production levels and the development of science and technology, the types, processes, design theories, calculation methods, and application ranges of pile foundations have greatly developed. They are widely used in engineering projects such as roads, ports, and bridges. Piles penetrate soft, highly compressible soil layers or water, transferring the load borne by the piles to a harder and denser bearing layer. In road engineering, piling is required according to different land conditions.

[0003] Patent CN218521782U discloses a high-efficiency piling device for road engineering, including a base plate. A pile hole is formed in the inner cavity at the center of the base plate. A connecting groove is provided at one end of the pile hole, located in the inner cavity of one side of the middle of the base plate. The connecting groove and the pile hole both penetrate through one side of the middle of the base plate. An action block is provided inside the connecting groove near the pile hole. Movable blocks are fixedly connected to both ends of the action block. Sliding grooves are provided on the outer sides of both sets of movable blocks, and these two sets of sliding grooves are respectively located on the inner walls of both sides of the connecting groove. Through the action block, movable blocks, sliding grooves, and tie rods, the effective horizontal movement of the action block facilitates the effective placement of the pile in the pile hole. In conjunction with the limiting block and fixing block, the action block is effectively limited overall. Furthermore, the arc plate and electric push rod provide excellent positioning assistance for the pile.

[0004] However, existing patents have the following drawbacks:

[0005] Existing piling devices can only drive piles to a fixed depth. However, due to different soil conditions in different regions, the piles that need to be driven also vary, which makes the piling devices quite limited.

[0006] Existing piling devices are equipped with casters, but the casters rotate during piling, causing the piling device to shake and thus causing the piling position to shift.

[0007] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0008] To solve the above problems, the technical solution of this utility model is: a piling device for road engineering, including a lifting structure and a fixing structure. It solves the problem that the existing piling devices can only drive piles to a fixed depth. However, due to different soil conditions in different regions, the piles that need to be driven are also different, which makes the piling device very limited. The piling device is equipped with casters, but the casters will rotate during piling, which will cause the piling device to shake and thus cause the piling position to shift.

[0009] Preferably, the substrate has four support legs fixedly connected to its lower end, and the substrate connecting plate has several handles fixedly connected to it.

[0010] The lifting housing is movably sleeved on the surface of the support leg;

[0011] A lifting structure, wherein the lifting structure is disposed at one end of the lifting housing;

[0012] A baffle plate is fixedly connected to the inner wall of the lifting housing;

[0013] A fixing structure is provided at the lower end of the baffle;

[0014] A fixing shell, two of which are fixedly connected to the upper end of the substrate;

[0015] A cylinder is fixedly connected to the upper end of a fixed housing, and a fixed block is fixedly connected to the output end of the cylinder. A piling nail is provided at the lower end of the fixed block.

[0016] A connecting hole is formed on the inner side of the substrate, and the surface of the piling nail is in contact with the inner wall of the connecting hole;

[0017] A guide rod is movably connected through the inside of the fixed block. The upper end of the guide rod is fixedly connected to the lower end of the inner wall of the fixed shell, and the lower end of the guide rod is fixedly connected to the upper end of the base plate.

[0018] Furthermore, the lifting structure includes a lifting rod fixedly connected to one end of the lifting housing, which is close to each other. A motor is fixedly connected to one end of the lifting rod, and a positive and negative lead screw is fixedly connected to the output end of the motor. The other end of the positive and negative lead screw is rotatably connected to one end of the other lifting rod. Two threaded blocks are threadedly connected to the surface of the positive and negative lead screw. Two hinge blocks are fixedly connected to the upper end of the threaded blocks. A connecting block is fixedly connected to the lower end of the base plate. Two hinge blocks are fixedly connected to both ends of the connecting block. A hinge rod is hinged to one end of the hinge blocks that is close to each other. The two sides of the other end of the hinge rod are hinged to the two ends of the hinge blocks that are close to each other.

[0019] Furthermore, the fixing structure includes an electric push rod fixedly connected to the lower end of the baffle, a sliding plate fixedly connected to the lower end of the electric push rod, a sliding groove opened on the lower side of the inner wall of the lifting shell, sliders fixedly connected to the four ends of the sliding plate, the sliders slidably connected to the inner side of the sliding groove, and a universal wheel fixedly connected to the lower end of the sliding plate.

[0020] Furthermore, a positioning sleeve is fixedly connected to the lower end of the substrate, and the inner wall of the positioning sleeve is in contact with the surface of the piling nail.

[0021] Furthermore, one of the support legs has scale lines on its surface.

[0022] The advantages of this invention compared to existing technologies are as follows:

[0023] This utility model utilizes a lifting structure. When in use, starting the motor causes the forward and reverse lead screws to rotate, which in turn causes the threaded blocks to move relative to each other. This causes one end of the hinge rod to swing. The hinge rod is hinged to the hinge block, causing the other end of the hinge rod to rise and fall. Since the lifting height of the hinge rod is less than the length of the lifting shell, it ensures that the lifting shell can slide stably on the surface of the support leg and will not detach from the support leg. This allows the support leg to rise and fall inside the lifting shell, thereby changing the height of the piling device and enabling the piling device to adapt to more terrains.

[0024] This utility model, through a fixed structure, allows the electric actuator to be activated during use, causing the slide plate to rise and fall via the slider and the slide groove, thereby causing the caster wheels to rise and fall, allowing the lifting shell to contact the ground, thus fixing the piling device and enabling the piling device to perform piling stably.

[0032] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0033] Example 1: As Figure 1-4 As shown, a piling device for road engineering includes: a base plate 1, a lifting shell 3, a lifting structure 4, a baffle 5, a fixing structure 6, a fixing shell 7, a cylinder 8, a connecting hole 11, and a guide rod 12. The lower end of the base plate 1 is fixedly connected to four support legs 2, and the two ends of the base plate 1 are fixedly connected to several handles. The lifting shell 3 is movably sleeved on the surface of the support legs 2. The lifting structure 4 is set at one end of the lifting shell 3. During use, the height of the piling device can be adjusted through the lifting structure 4, so as to adapt to various terrains and soils. The handles can be manually pressed to fix the device when the machine vibrates.

[0034] The baffle 5 is fixedly connected to the inner wall of the lifting shell 3, and the fixing structure 6 is set at the lower end of the baffle 5. When in use, the piling device can be fixed on the ground through the fixing structure 6, so that the piling device can drive piles stably.

[0035] Two fixed housings 7 are fixedly connected to the upper end of the base plate 1. A cylinder 8 is fixedly connected to the upper end of the fixed housings 7. A fixed block 9 is fixedly connected to the output end of the cylinder 8. A piling nail 10 is provided at the lower end of the fixed block 9. A connecting hole 11 is opened on the inner side of the base plate 1. The surface of the piling nail 10 is in contact with the inner wall of the connecting hole 11. When in use, the cylinder 8 is activated to make the fixed block 9 start to rise and fall, so that the piling nail 10 can be driven into place.

[0036] The guide rod 12 is movably connected to the inside of the fixed block 9. The upper end of the guide rod 12 is fixedly connected to the lower end of the inner wall of the fixed shell 7, and the lower end of the guide rod 12 is fixedly connected to the upper end of the base plate 1. When in use, it can make the fixed block 9 run more stably, so that the piling nail 10 can be driven into the pile stably.

[0037] The lifting structure 4 includes a lifting rod 401 fixedly connected to one end of the lifting housing 3. A motor 402 is fixedly connected to one end of the lifting rod 401. A positive and negative lead screw 403 is fixedly connected to the output end of the motor 402. The other end of the positive and negative lead screw 403 is rotatably connected to one end of the other lifting rod 401. Two threaded blocks 404 are threadedly connected to the surface of the positive and negative lead screw 403. Two hinge blocks 405 are fixedly connected to the upper end of the threaded blocks 404. A connecting block 406 is fixedly connected to the lower end of the base plate 1. Two hinge blocks 407 are fixedly connected to both ends of the connecting block 406. A hinge rod 408 is hinged to one end of the hinge blocks 405 that is close to each other. The other end of the hinge rod 408... The two sides are hinged to the two ends of the hinge block 407 that are close to each other. When in use, the motor 402 is started, which causes the positive and negative lead screws 403 to start rotating, which causes the threaded block 404 to start moving relative to each other, which causes one end of the hinge rod 408 to start swinging. The hinge rod 408 is hinged to the hinge block 407, which causes the other end of the hinge rod 408 to start rising and falling. The rising and falling height of the hinge rod 408 is less than the length of the lifting shell 3, which ensures that the lifting shell 3 can slide stably on the surface of the support leg 2 and will not detach from the support leg 2. This allows the support leg 2 to rise and fall inside the lifting shell 3, thereby changing the height of the piling device and making the piling device adaptable to more terrains.

A universal wheel 605 is fixedly connected to the lower end of the sliding plate 602. When in use, the electric push rod 601 is activated, which causes the sliding plate 602 to start rising and falling through the slider 604 and the groove 603, thereby causing the universal wheel 605 to start rising and falling. This allows the lifting shell 3 to contact the ground, thereby fixing the piling device and enabling the piling device to perform piling stably.
