Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a steel pipe pile driving device. Background Technology

[0002] Steel pipe pile driving equipment refers to a series of specialized machines that drive steel pipe piles vertically, efficiently, and accurately into the foundation to achieve a predetermined depth and bearing capacity. Its core function and ultimate purpose is to make steel pipe piles a reliable support for the foundations of buildings, bridges, equipment, etc.

[0003] Currently, traditional steel pipe pile driving devices have a fixed driving height. When operating indoors, the overall height of the device cannot be adjusted according to the actual indoor height, making it impossible for the steel pipe pile driving device to enter the room, resulting in poor practicality. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the overall height of traditional steel pipe pile driving devices cannot be adjusted, making it difficult to rotate and operate flexibly in narrow spaces.

[0005] To solve the above-mentioned technical problems, this utility model provides a steel pipe pile driving device, which includes a frame, a column, a driving assembly, and a drive mechanism. The frame supports the steel pipe pile driving device. The column is fixedly installed on the frame, and a jack is installed inside the column. One end of the jack is connected to the frame, and the other end of the jack is an output end connected to the column, used to drive the column to move up and down vertically. The driving assembly is located on one side of the column and includes a steel pipe pile, a guide tube, and a hammer. The steel pipe pile is inserted vertically into the ground. The guide tube is located between the hammer and the steel pipe pile, and the guide tube has a channel for the hammer to pass through. The hammer is located at the top of the steel pipe pile and moves up and down vertically under the guidance of the guide tube to hammer the steel pipe pile. The drive mechanism is located on the other side of the column and is connected to the hammer via a suspension rope.

[0006] In one embodiment, the piling assembly further includes a pile support mounted on the frame for temporarily fixing the steel pipe piles before piling.

[0007] In one embodiment, there are two pile supports, which are symmetrically arranged inside the frame. Each pile support includes a connecting rod and a clamping part. One end of the connecting rod is connected to the frame and the other end is connected to the clamping part. Each clamping part has an arc-shaped clamping surface at the end opposite to the connecting rod. The two clamping parts surround each other to form a limiting channel for fixing the steel pipe pile.

[0008] In one embodiment, the piling assembly further includes a rotating mechanism, one end of which is rotatably connected to the frame and the other end is fixedly connected to the guide tube. The rotating mechanism is used to drive the guide tube to rotate in the horizontal direction.

[0009] In one embodiment, the guide tube includes two symmetrically arranged half-pipes, one end of which is rotatably connected and the other end is fixed by a pin. The guide tube is used to wrap the steel pipe pile.

[0010] In one embodiment, the bottom of the frame is also provided with a support base, the number of which is at least four. The support bases are respectively located at the corners of the frame, and each support base is hydraulically driven to extend and retract in the vertical direction to support the frame.

[0011] In one embodiment, the support base includes a support rod and a support portion. One end of the support rod is connected to the frame, and the other end is connected to the support portion. The support portion is used to abut against the ground, and the outer diameter of the support portion is larger than the outer diameter of the connecting rod.

[0012] In one embodiment, a moving mechanism is also provided at the bottom of the frame. The moving mechanism includes moving wheels and tracks. The moving wheels are respectively provided on both sides of the frame, and the tracks are wrapped around the outer periphery of the moving wheels. The rotation of the moving wheels drives the tracks to move, thereby driving the frame to move.

[0013] In one embodiment, the drive mechanism includes a motor, which is fixedly mounted on the frame. The output end of the motor winds up and unwinds a rope via a drum. The motor is used to drive the hammer to reciprocate in the vertical direction via the rope.

[0014] In one embodiment, a lifting lug is fixedly installed at one end of the lifting rope near the hammer, and the lifting rope is detachably connected to the hammer through the lifting lug.

[0015] Compared with the prior art, the steel pipe pile driving device of this utility model has the following advantages: by embedding jacks in the column, the height of the column can be flexibly adjusted, ensuring that when the device is used for indoor operations, the height of the column can be adjusted according to the actual indoor height, so that the device has an adaptive height adjustment function and can flexibly move and position in extremely narrow spaces that traditional pile driving equipment cannot enter, such as indoor spaces, underground foundation pits, and gaps between existing buildings.

[0020] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0021] In the description of this utility model, it should be understood that when an element is referred to as "fixed to" or "set on" another element, it can be directly on or indirectly on the other element. When an element is referred to as "connected to" another element, it can be directly connected to or indirectly connected to the other element. The terms "mounted," "connected," and "attached" 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; they can refer to the internal communication of two elements or the interaction between two elements. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0022] In the description of this utility model, it should be understood that the terms "height," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer" used to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0023] In the description of this utility model, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0024] like Figures 1 to 3 As shown, this utility model preferably provides a steel pipe pile driving device, which includes a frame 10, a column 20, a driving assembly 30, and a drive mechanism 40. The frame 10 supports the steel pipe pile driving device. The column 20 is fixedly installed on the frame 10, and a jack 21 is provided inside the column 20. One end of the jack 21 is connected to the frame 10, and the other end of the jack 21 is an output end and connected to the column 20, used to drive the column 20 to move up and down in the vertical direction. The driving assembly 30 is disposed on one side of the column 20. The component 30 includes a steel pipe pile 31, a guide tube 32, and a hammer 33. The steel pipe pile 31 is inserted vertically into the ground. The guide tube 32 is located between the hammer 33 and the steel pipe pile 31, and the guide tube 32 has a channel inside for the hammer 33 to pass through. The hammer 33 is located on the top of the steel pipe pile 31. Under the guidance of the guide tube 32, the hammer 33 moves up and down vertically to hammer the steel pipe pile 31. The drive mechanism 40 is located on the other side of the column component 20. The drive mechanism 40 is connected to the hammer 33 through a suspension rope 42.

[0025] Based on the above technical features, this utility model embodiment uses the design of embedding a jack 21 inside the column component 20 to achieve flexible height adjustment of the column component 20. This ensures that when the device is used for indoor operations, the height of the column component can be adjusted according to the actual indoor height, so that the device has an adaptive height adjustment function and can flexibly move and position itself in extremely narrow spaces such as indoor spaces, underground foundation pits, and gaps between existing buildings, which are inaccessible to traditional large piling equipment.

[0026] Furthermore, by setting a guide tube 32 with an internal channel, a precise rigid guide is provided for the up-and-down reciprocating motion of the hammer 33. This design can effectively constrain the movement trajectory of the hammer 33, ensuring that its hammering force always acts vertically on the center of the top of the steel pipe pile 31, fundamentally avoiding problems such as pile tilting and pile head damage caused by eccentric hammering, and greatly improving the quality and vertical accuracy of pile driving.

[0027] As some embodiments of this utility model, such as Figure 1 As shown, the piling assembly 30 also includes a pile support 34, which is mounted on the frame 10 and used to temporarily fix the steel pipe pile 31 before piling. The pile support 34 provides a clear mechanical support and clamping point for the steel pipe pile 31. During the hoisting process, the operator does not need to manually stabilize the heavy steel pipe pile 31 throughout the process; they only need to lower its lower end into the interior of the pile support 34 to complete the initial fixation. This greatly simplifies the alignment process, shortens the auxiliary time, and ensures rapid and accurate initial positioning.

[0028] As some embodiments of this utility model, such as Figures 1 to 2As shown, there are two pile supports 34, which are symmetrically arranged inside the frame 10. Each pile support 34 includes a connecting rod 341 and a clamping part 342. One end of the connecting rod 341 is connected to the frame 10, and the other end is connected to the clamping part 342. Each clamping part 342 has an arc-shaped clamping surface at the end opposite to the connecting rod 341. The two clamping parts 342 surround each other to form a limiting channel for fixing the steel pipe pile 31. By employing two symmetrically arranged pile supports 34 inside the frame 10, with each pile support 34 having an arc-shaped clamping surface at the end of its clamping part 342, forming a limiting channel together, the symmetrical double-support structure evenly distributes the weight of the pile and the impact force it receives to the two symmetrical support points of the frame 10, avoiding the torque and torsion that may be generated by single-point support. This design ensures that the steel pipe pile 31 is in a mechanically symmetrical and stable state before the hammering begins. The arc-shaped clamping surface design changes the contact form between the steel pipe pile 31 and the pile from point contact or line contact to surface contact. The increased contact area significantly reduces the pressure of the clamping part 342 on the surface of the steel pipe pile 31, effectively avoiding damage to the surface of the steel pipe pile 31.

[0029] As some embodiments of this utility model, such as Figures 1 to 2 As shown, the piling assembly 30 also includes a rotating mechanism 35. One end of the rotating mechanism 35 is rotatably connected to the frame 10, and the other end is fixedly connected to the guide tube 32. The rotating mechanism 35 is used to drive the guide tube 32 to rotate in the horizontal direction. By adding a rotating mechanism 35 between the guide tube 32 and the frame 10, the horizontal rotation of the guide tube 32 is achieved, allowing the guide tube 32 to quickly move to a preset position during use and rotate back to the initial position when not in use, providing a wide and direct operating space and facilitating daily maintenance and inspection of the guide tube 32.

[0030] As some embodiments of this utility model, such as Figures 1 to 2 As shown, the guide tube 32 includes two symmetrically arranged semi-tube bodies 321. One end of the two semi-tube bodies 321 is rotatably connected, and the other end is fixed by a pin. The guide tube 32 is used to wrap the steel pipe pile 31. By designing the guide tube 32 as two symmetrical semi-tube bodies 321, with one end rotatably connected and the other end fixed by a pin, this design allows the guide tube 32 to actively open and close. When hoisting the steel pipe pile 31, the guide tube 32 can be opened to provide a completely unobstructed vertical space for the hoisting operation; after the pile body is fixed, the guide tube 32 is closed to wrap it. This operation process does not require moving the entire equipment or precise alignment, and the process is extremely smooth.

[0031] As some embodiments of this utility model, such as Figure 2As shown, the bottom of the frame 10 is also equipped with support seats 11. There are at least four support seats 11, which are located at the corners of the frame 10. Each support seat 11 is hydraulically driven to extend and retract vertically to support the frame 10. The four support seats 11 distributed at the corners of the frame 10 form a multi-point support system, creating a large and stable support rectangle. When the hammer 33 violently strikes the steel pipe pile 31, it generates enormous impact force and vibration. This support system can effectively and evenly transfer these forces to the ground, greatly suppressing the swaying and tilting of the frame 10, providing a rock-solid working platform for high-precision piling.

[0032] As some embodiments of this utility model, such as Figure 1 As shown, the support base 11 includes a support rod 111 and a support portion 112. One end of the support rod 111 is connected to the frame 10, and the other end is connected to the support portion 112. The support portion 112 is used to abut against the ground, and the outer diameter of the support portion 112 is larger than the outer diameter of the connecting rod 341. Through the design of the support rod 111 and the support portion 112, and the fact that the outer diameter of the support portion 112 is larger than the outer diameter of the support rod 111, the contact area between the support base 11 and the ground is effectively increased, significantly enhancing the grounding stability of the support base 11.

[0033] As some embodiments of this utility model, such as Figure 1 As shown, a moving mechanism 12 is also provided at the bottom of the frame 10. The moving mechanism 12 includes moving wheels 121 and tracks 122. The moving wheels 121 are respectively disposed on both sides of the frame 10, and the tracks 122 are wrapped around the outer periphery of the moving wheels. The rotation of the moving wheels drives the tracks 122 to move, thereby driving the frame 10 to move. The moving wheels 121 are suitable for fast movement on flat roads, while the tracks 122 can handle complex terrains such as mud and gravel. The combination of the two enhances the frame 10's ability to pass through different ground environments.

[0034] As some embodiments of this utility model, such as Figure 1 As shown, the drive mechanism 40 includes a motor 41, which is fixedly mounted on the frame 10. The output end of the motor 41 winds up and down a hoisting rope 42 via a drum. The motor 41 drives the hammer 33 to reciprocate vertically via the hoisting rope 42. By winding up and down the hoisting rope 42, the motor 41 can precisely control the lifting speed, stroke, and position of the hammer 33. For example, by adjusting the speed of the motor 41, the hammer 33 can be rapidly lowered or slowly raised to meet the precise impact force requirements of different operating scenarios. The vertical reciprocating movement design ensures that the hammer 33 always moves along a vertical trajectory, avoiding energy loss or equipment damage caused by deviation, and improving operating efficiency and safety.

[0035] As some embodiments of this utility model, such as Figure 1As shown, a lifting lug 421 is fixedly installed at one end of the lifting rope 42 near the hammer 33, and the lifting rope 42 is detachably connected to the hammer 33 through the lifting lug 421. The design of the lifting lug 421 allows for the replacement of hammers 33 of different specifications, enabling quick adjustment of the device's operating mode.

[0036] In summary, the steel pipe pile driving device provided by this utility model has the following advantages compared with the prior art: The design of the jack 21 embedded in the column 20 allows for flexible height adjustment of the column 20, ensuring that the height of the column can be adjusted according to the actual indoor height when the device is used for indoor operations. This gives the device an adaptive height adjustment function. The narrow frame 10 allows for flexible movement and positioning in extremely narrow spaces such as indoor spaces, underground foundation pits, and gaps between existing buildings, where traditional large-scale piling equipment cannot enter. The guide tube 32 with an internal channel provides precise rigid guidance for the reciprocating motion of the hammer 33. This design effectively constrains the movement trajectory of the hammer 33, ensuring that its hammering force always acts perpendicularly to the center of the top of the steel pipe pile 31, fundamentally avoiding problems such as pile tilting and pile head damage caused by eccentric hammering, and greatly improving the quality and vertical accuracy of piling.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
