Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a piling device for building engineering. Background Technology

[0002] Existing piling devices for building construction suffer from technical problems such as low efficiency and uneven impact force, making it difficult to flexibly and accurately adjust to the actual height of the piles during construction. Traditional piling equipment typically employs fixed or semi-automatic lifting structures, resulting in poor adaptability to piles of varying heights and requiring frequent manual intervention to adjust the position, which not only affects construction accuracy but also reduces work efficiency. Furthermore, conventional piling mechanisms often rely on hydraulic or pneumatic systems to drive the hammer for vertical impact, leading to complex structures, high maintenance costs, and significant energy transfer losses. Therefore, we propose a piling device for building construction. Utility Model Content

[0003] The main objective of this invention is to provide a piling device for building construction, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A piling device for construction engineering includes a base plate, three support rods fixedly installed on the upper end of the base plate and a lead screw movably connected thereto, a top plate fixedly installed on the top of the three support rods, the top of the lead screw penetrating the top plate and movably connected to the top plate through a bearing, a forward and reverse motor fixedly installed on the top of the top plate, the output end of the forward and reverse motor being fixedly connected to the lead screw, and a lifting assembly slidably connected between the support rods and the lead screw at the rear, the lifting assembly being equipped with a piling mechanism; The piling mechanism includes a drive component movably mounted on the lifting assembly, and a piling component slidably connected to the front of the lifting assembly, wherein the drive component and the piling component are movably connected.

[0005] Preferably, the lifting assembly includes a lifting plate, and both ends of the lifting plate are fixedly welded with transmission ears. One transmission ear is slidably sleeved on the support rod, and the other transmission ear is threadedly connected to the lead screw.

[0006] By adopting the above technical solution, the lifting drive is achieved by the cooperation of the lead screw and the threaded transmission ear, while the other transmission ear slides and guides on the support rod, ensuring that the lifting plate runs smoothly and does not deflect during the lifting process, thereby improving the lifting accuracy and structural stability.

[0007] Preferably, the front end of the lifting plate is symmetrically connected to two slide rails, and the cross-section of the slide rails is an "I" shaped structure.

[0008] By adopting the above technical solution, the "I"-shaped slide rail can effectively limit the lateral and vertical degrees of freedom of the slide sleeve, provide good guiding performance and resistance to lateral forces, ensure stable and smooth up-and-down movement of the piling assembly, and reduce vibration and displacement.

[0009] Preferably, the piling mechanism includes a drive motor fixedly installed at the rear end of the lifting plate, a rotating rod fixedly connected to the output end of the drive motor, a drive disk fixedly connected to the front end of the rotating rod, a drive rod movably connected to the front end of the drive disk away from the center, and a transmission rod movably connected to the bottom of the drive rod and movably connected to the piling assembly.

[0010] By adopting the above technical solution, the rotational motion of the drive motor is converted into the eccentric oscillation of the drive disc, and then the drive rod and transmission rod drive the piling assembly to reciprocate, thereby realizing continuous automatic piling. The structure is simple and the transmission efficiency is high.

[0011] Preferably, the piling assembly includes an impact platform, a sliding sleeve that is slidably connected to a slide rail is fixedly connected to the rear end of the impact platform, a connecting rod is fixedly connected to the front end of the impact platform, the connecting rod is movably connected to a transmission rod, a hammer head is inserted into the lower end of the impact platform, and a pad block is integrally formed at the bottom of the hammer head.

[0012] By adopting the above technical solution: the impact table slides up and down along the slide rail through the sliding sleeve and is driven by the transmission rod to achieve stable impact. The hammer head can be disassembled and replaced, and the pad increases the contact area, protects the top of the foundation pile, and improves the uniformity and safety of pile driving.

[0013] Preferably, the front end of the base plate is provided with a through groove, and the position of the through groove corresponds to the position of the pad block.

[0014] By adopting the above technical solution, sufficient space is provided for the downward movement of the hammer and pad during the pile driving process, avoiding structural interference with the base plate and ensuring the complete and smooth execution of the pile driving action.

[0015] Preferably, the base plate is fixedly welded to each of its four corners.

[0016] By adopting the above technical solution, the entire device can be securely installed on the ground or construction platform using bolts or other fasteners, enhancing the overall stability of the equipment, preventing displacement or overturning due to vibration during pile driving, and improving operational safety.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the coordinated design of the lifting assembly and the lead screw transmission system, the piling mechanism achieves precise and stepless adjustment in the vertical direction. Since the lead screw is directly driven by a forward and reverse motor, and in conjunction with the bearing support structure on the top plate, the process of converting rotational motion into linear motion is smooth and reliable. One side of the lifting plate is threadedly connected to the lead screw via a transmission lug, while the other side is slidably connected to the support rod, forming a stable guiding and bearing structure. This effectively prevents deflection or swaying during the lifting process. This structure not only allows for rapid adjustment of the piling mechanism's position according to the different heights of the foundation piles at the construction site, ensuring that the hammer head is always aligned with the center axis of the foundation pile, thus improving the verticality and accuracy of piling, but also features a high degree of automation in the entire adjustment process, reducing manual measurement and calibration steps and significantly improving construction safety and work efficiency.

[0018] 2. The piling mechanism adopts a mechanical crank-slider linkage structure, realizing continuous and stable high-frequency impact piling function. The drive motor drives the transmission rod through the drive disc and drive rod to push the impact table to slide back and forth along the "I"-shaped slide rail. This slide rail structure has good resistance to lateral forces, ensuring that the movement trajectory is straight during the impact process and reducing vibration deviation. At the same time, the hammer head is detachably connected to the bottom of the impact table, which makes it easy to replace hammer heads of different weights or shapes to adapt to different geological conditions and piling requirements, enhancing the applicability of the equipment. More importantly, this mechanical transmission scheme does not require hydraulic cylinders or compressed air support, has a compact structure, is easy to maintain, has low operating costs, and the impact frequency can be precisely controlled by adjusting the speed of the drive motor to meet the needs of various working conditions, thereby achieving efficient, energy-saving and stable piling operations.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figure 1-4 This utility model provides a technical solution: A piling device for construction engineering includes a base plate 1. Three support rods 2 are fixedly installed on the upper end of the base plate 1 and a lead screw 3 is movably connected thereto. A top plate 4 is fixedly installed on the top of the three support rods 2. The top of the lead screw 3 passes through the top plate 4 and is movably connected to the top plate 4 through a bearing. A forward and reverse motor 5 is fixedly installed on the top of the top plate 4. The output end of the forward and reverse motor 5 is fixedly connected to the lead screw 3. A lifting assembly 6 is slidably connected between the support rods 2 and the lead screw 3 at the rear. A piling mechanism 7 is provided on the lifting assembly 6. Fixing plates 12 are fixedly welded to the four corners of the base plate 1.

[0025] In this embodiment, the lifting assembly 6 includes a lifting plate 61. Both the left and right ends of the lifting plate 61 are fixedly welded with transmission ears 62. One transmission ear 62 is slidably sleeved on the support rod 2, and the other transmission ear 62 is threadedly connected to the lead screw 3. The front end of the lifting plate 61 is symmetrically connected with two slide rails 63, and the cross-section of the slide rails 63 is an "I" shaped structure.

[0026] Through the above scheme, the piling mechanism 7 achieves precise and stepless adjustment in the vertical direction by coordinating the lifting assembly 6 with the screw drive system. Since the screw 3 is directly driven by the forward and reverse motors 5, and with the bearing support structure on the top plate 4, the process of converting rotational motion into linear motion is smooth and reliable. One side of the lifting plate 61 is threadedly connected to the screw 3 through the transmission lug 62, and the other side is slidably connected to the support rod 2, forming a stable guiding and bearing structure, effectively preventing deflection or shaking during the lifting process. This structure can not only quickly adjust the position of the piling mechanism according to the different heights of the foundation piles at the construction site, ensuring that the hammer head 724 is always aligned with the central axis of the foundation pile, improving the verticality and accuracy of piling, but also has a high degree of automation in the entire adjustment process, reducing manual measurement and calibration, and significantly improving construction safety and work efficiency.

[0027] In this embodiment, the piling mechanism 7 includes a drive assembly 71 movably mounted on the lifting assembly 6, and a piling assembly 72 slidably connected to the front of the lifting assembly 6. The drive assembly 71 and the piling assembly 72 are movably connected. The piling mechanism 7 includes a drive motor 711 fixedly mounted on the rear end of the lifting plate 61. A rotating rod 712 is fixedly connected to the output end of the drive motor 711. A drive disk 713 is fixedly connected to the front end of the rotating rod 712. A drive rod 714 is movably connected to the front end of the drive disk 713 away from the center. A drive rod 714 is movably connected to the bottom of the drive rod 714. A transmission rod 715 is movably connected to the piling assembly 72; the piling assembly 72 includes an impact table 721, a sliding sleeve 722 that is slidably connected to the slide rail 63 is fixedly connected to the rear end of the impact table 721, a connecting rod 723 is fixedly connected to the front end of the impact table 721, the connecting rod 723 is movably connected to the transmission rod 715, a hammer head 724 is inserted through the lower end of the impact table 721, and a pad block 725 is integrally formed at the bottom of the hammer head 724; the front end of the base plate 1 is provided with a vertically through clearance groove 11, and the position of the clearance groove 11 corresponds to the position of the pad block 725.

[0028] Through the above scheme: the piling mechanism 7 adopts a mechanical crank-slider linkage structure, realizing continuous and stable high-frequency impact piling function. The drive motor 711 drives the transmission rod 715 through the drive disc 713 and drive rod 714 to push the impact table 721 to slide back and forth along the "I"-shaped slide rail 63. The slide rail 63 has good resistance to lateral force, ensuring that the movement trajectory is straight during the impact and reducing vibration deviation. At the same time, the hammer head 724 is detachably connected to the bottom of the impact table 721, which makes it easy to replace hammer heads of different weights or shapes to adapt to different geological conditions and piling requirements, thus enhancing the applicability of the equipment. More importantly, this mechanical transmission scheme does not require hydraulic cylinders or compressed air support, has a compact structure, is easy to maintain, has low operating costs, and the impact frequency can be precisely controlled by adjusting the speed of the drive motor to meet the needs of various working conditions, thereby achieving efficient, energy-saving and stable piling operations.

[0029] It should be noted that this utility model is a piling device for construction engineering. During use, firstly, the device is moved to the designated construction location and firmly fixed to the ground or work platform by the fixing plates 12 welded to the four corners of the base plate 1, ensuring the equipment remains stable during operation and preventing displacement or overturning due to vibration. Next, according to the actual height of the foundation pile to be constructed, the forward and reverse motors 5 above the top plate 4 are activated. The forward and reverse motors 5 drive the lead screw 3, which is fixedly connected to its output end, to rotate. Since the lead screw 3 is movably connected to the top plate 4 through bearings, its rotation drives the lifting plate 61 in the lifting assembly 6 to move up and down vertically. Specifically, one end of the lifting plate 61 is threaded onto the lead screw 3 through a transmission lug 62, while the other end of the transmission lug 62 is slidably fitted onto the support rod 2, forming a guiding and limiting structure. As the lead screw 3 rotates forward or reverse, the lifting plate 61 can smoothly and accurately rise and fall to a height aligned with the top of the foundation pile. This ensures the vertical accuracy of subsequent piling operations. Once the lifting plate 61 is in place, the drive motor 711 in the piling mechanism 7 is activated. The rotational power of the drive motor 711 is transmitted to the drive disc 713 at the front end through the rotating rod 712. The drive disc 713 is eccentrically hinged with a drive rod 714. The other end of the drive rod 714 is connected to the transmission rod 715, which is hinged to the connecting rod 723 of the piling assembly 72. As the drive disc 713 continues to rotate, the drive rod 714 drives the transmission rod 715 to reciprocate, thereby pushing the impact table 721 to move vertically up and down along the "I"-shaped slide rail 63 at the front end of the lifting plate 61. The hammer head 724 connected to the lower end of the impact table 721 then strikes the top of the foundation pile at a high frequency. The integrally formed pad block 725 at its bottom increases the contact area and reduces local stress damage. When the hammer head descends, the clearance groove 11 at the front end of the base plate 1 provides sufficient space for movement to avoid structural interference. This mechanical linkage method enables continuous, stable, and efficient pile driving operations. The entire process requires no hydraulic system, has a simple and reliable structure, is easy to maintain, and is suitable for various construction engineering scenarios.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
