Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, and in particular to a building pile driver for building construction. Background Technology

[0002] Construction engineering refers to the engineering entities formed by the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. It encompasses the construction of various infrastructures such as residential buildings, commercial buildings, industrial plants, bridges, and dams. It is an important pillar industry for national economic development and is directly related to people's production and life and social progress and development.

[0003] In building construction, in order to enhance the stability of the building foundation and prevent problems such as foundation settlement, it is often necessary to drive piles into the ground to transfer the building load to the deep, solid soil or rock layers. The building pile driver is the key equipment to achieve this operation. It uses a power device to drive the hammer head to rise and fall, and uses impact force to drive the pile into the foundation. It is an indispensable and important machine in the building foundation construction process.

[0004] The existing pile driver for building construction has the following shortcomings:

[0005] Because of the lack of an adaptive clamping structure for the pile, the pile is prone to lateral swaying due to impact force during the pile driving process, resulting in deviation of the pile's verticality and affecting the stability of the foundation. At the same time, the existing device has a fixed lifting range for the pile driving components and cannot adjust the height synchronously with the sinking of the pile. After the pile is driven to a certain depth, the machine needs to be stopped and the position of the equipment adjusted before it can continue to work, which not only reduces the efficiency of pile driving but also increases the complexity of operation. Utility Model Content

A pressure wheel is rotatably connected to the bottom end of the rotating arm, and a connecting column is fixedly connected to the top of the opposite side of the two rotating arms.

[0009] Preferably, the positioning component further includes two limiting baffles, which are fixedly connected to the top of the support base. A first screw is rotatably connected to the opposite surfaces of the two limiting baffles. A threaded slider is threadedly connected to the outer surface of the first screw, and the top of the threaded slider is movably connected to the bottom end of the pulling rod.

[0010] Preferably, a first motor is fixedly connected to the side of the limiting baffle, and the output shaft of the first motor is fixedly connected to the first screw.

[0011] Preferably, the lifting assembly includes a gantry frame, which is fixedly connected to the top rear side of the support base. A second motor is fixedly connected to the top center of the gantry frame. The output shaft of the second motor passes through the inner side of the gantry frame and is fixedly connected to a second screw. Guide columns are fixedly connected to both the left and right sides of the inner side of the gantry frame.

[0012] Preferably, the piling assembly includes a connecting slide plate, the rear end of which has a threaded hole extending vertically through the center, the inner surface of which is threadedly connected to the outer surface of the second screw, and the rear end of the connecting slide plate has guide sliding holes extending vertically through the left and right sides, the inner surface of which is slidably connected to the outer surface of the guide post.

[0013] Preferably, the front side of the connecting slide plate is slidably connected to a reciprocating slide column that runs vertically through it, the bottom end of the reciprocating slide column is fixedly connected to a piling block, and the top end of the reciprocating slide column is fixedly connected to a lifting sleeve plate.

[0014] Preferably, support plates are fixedly connected to the top front left and right sides of the connecting slide plate, a third motor is fixedly connected to the top of the opposite sides of the two support plates, and a drive arm is rotatably connected to the opposite sides of the two support plates.

[0015] Preferably, the drive arm includes two rotating plates, the top of which is fixedly connected to the output shaft of a third motor, and a connecting groove extending through the middle of the rotating plate. An adjusting slide plate is slidably connected to the inner surface of the connecting groove.

[0016] Preferably, a drive column is fixedly connected to the opposite surfaces of the two adjusting slide plates, and a straight slot that runs through the middle of the lifting sleeve is provided, with the outer surface of the drive column slidably connected to the inner surface of the straight slot.

[0017] Preferably, a third screw is rotatably connected to the middle of the connecting groove, the outer surface of the third screw is threadedly connected to the middle of the adjusting slide plate, and the bottom end of the third screw extends through to the bottom of the rotating plate and is fixedly connected to a knob.

[0018] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0019] 1. In this utility model, dynamic clamping of the pile is achieved through the cooperation of the first motor, the first screw, the threaded slider, the pulling rod, the connecting column, the rotating arm, and the clamping wheel. The principle is that the first motor drives the first screw to rotate, causing the threaded slider to slide along the screw's axial direction. This, in turn, pulls the connecting column via the pulling rod, causing the rotating arm to rotate around the support frame. This allows the clamping wheel to contact the pile surface from both sides. This structure reduces the lateral sway of the pile during driving through the clamping force of the clamping wheel, ensuring the pile's verticality. Furthermore, it utilizes the rotational characteristics of the clamping wheel to avoid generating additional resistance during pile sinking, achieving synergy between clamping and sinking actions. This solves the problem of pile sway affecting construction accuracy in traditional devices.

[0020] 2. In this utility model, through the mutual cooperation of the third motor, rotating plate, drive column, lifting sleeve plate, reciprocating slide column, pile driving block, lifting assembly, third screw, and adjusting slide plate, efficient and adjustable pile driving operation is achieved. The principle is that the third motor drives the rotating plate to rotate, causing the drive column to move along the connecting slide groove of the rotating plate. Simultaneously, through sliding cooperation with the straight groove of the lifting sleeve plate, the circular motion is converted into the up-and-down reciprocating motion of the lifting sleeve plate. This, in turn, drives the pile driving block to strike the pile body at high frequency via the reciprocating slide column. The lifting assembly, driven by the second motor, rotates the second screw, causing the connecting slide plate to rise and fall along the guide column, achieving synchronous height adjustment of the pile driving assembly as the pile body sinks. When the knob is turned, driving the third screw, the adjusting slide plate slides along the connecting slide groove, changing the movement radius of the drive column and thus adjusting the lifting stroke of the pile driving block. This structure not only improves pile driving efficiency through continuous reciprocating striking and synchronous height adjustment, but also allows for flexible adjustment of the impact force according to the pile material and construction requirements, solving the problem of fixed pile driving range and frequent shutdowns for adjustment in traditional devices, thus improving the applicability and ease of operation of the equipment.

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0029] Example 1: As Figure 1 and Figure 2As shown, this utility model provides a technical solution: it includes a support base 1, with a U-shaped connecting groove 11 extending vertically through the center of the front side of the support base 1. Positioning components 2 are provided on both the left and right sides of the top front side of the support base 1. A lifting component 3 is fixedly connected to the rear side of the top of the support base 1. A piling component 4 is slidably connected to the front side of the lifting component 3. The positioning component 2 includes a support frame 21, with two support frames 21 fixedly connected to the left and right sides of the top front side of the support base 1 respectively. Rotating arms 22 are rotatably connected to both the front and rear sides of the support frame 21, and pressure wheels 23 are rotatably connected to the bottom end of the rotating arms 22. The top of the opposite faces of the two rotating arms 22 are fixedly connected to the connecting column 24, and the outer surface of the connecting column 24 is rotatably connected to the pull rod 25. The positioning component 2 also includes two limiting baffles 26. The limiting baffles 26 are fixedly connected to the top of the support base 1. The opposite faces of the two limiting baffles 26 are rotatably connected to a first screw 28. The outer surface of the first screw 28 is threadedly connected to a threaded slider 29. The top of the threaded slider 29 is movably connected to the bottom end of the pull rod 25. The side of the limiting baffle 26 is fixedly connected to a first motor 27. The output shaft of the first motor 27 is fixedly connected to the first screw 28.

[0030] The overall effect of Embodiment 1 is as follows: When the first motor 27 starts, its output shaft drives the first screw 28 to rotate between the two limit baffles 26. The threaded slider 29 then slides along the axial direction of the first screw 28, thereby pulling the connecting column 24 through the pulling rod 25, causing the rotating arm 22 to rotate around the support frame 21. At this time, the clamping wheel 23 at the bottom of the rotating arm 22 approaches the pile body from both sides and fits tightly, which can form a stable clamp for piles of different diameters, effectively reducing the lateral sway of the pile body caused by the impact force during the pile driving process, ensuring the verticality of the pile body. At the same time, during the sinking process of the pile body being driven into the ground, the clamping wheel 23 rotates synchronously with the pile body, avoiding additional resistance to the sinking of the pile body, realizing the coordinated operation of clamping and sinking actions, and significantly improving the construction accuracy of pile driving.

[0031] Example 2: Figure 3 , Figure 4 and Figure 5As shown, this utility model provides a technical solution: the lifting assembly 3 includes a gantry frame 31, which is fixedly connected to the top rear side of the support base 1. A second motor 32 is fixedly connected to the middle of the top of the gantry frame 31. The output shaft of the second motor 32 passes through the inner side of the gantry frame 31 and is fixedly connected to a second screw 33. Guide columns 34 are fixedly connected to the left and right sides of the inner side of the gantry frame 31. The piling assembly 4 includes a connecting slide plate 41. A threaded hole 42 is opened in the middle of the rear end of the connecting slide plate 41. The inner surface of the threaded hole 42 is threadedly connected to the outer surface of the second screw 33. Guide sliding holes 43 are opened in the left and right sides of the rear end of the connecting slide plate 41. The inner surface of the guide sliding hole 43 is slidably connected to the outer surface of the guide column 34. A reciprocating sliding column 44 is slidably connected to the front side of the connecting slide plate 41. A piling block 45 is fixedly connected to the bottom end of the reciprocating sliding column 44. A lifting sleeve plate 46 is fixedly connected to the top end of the reciprocating sliding column 44. Support plates 47 are fixedly connected to the top front side of plate 41 on both the left and right sides. A third motor 48 is fixedly connected to the top of the opposite sides of the two support plates 47. A drive arm 49 is rotatably connected to the opposite sides of the two support plates 47. The drive arm 49 includes two rotating plates 491. The top of the rotating plates 491 is fixedly connected to the output shaft of the third motor 48. A connecting groove 492 that runs through the left and right is opened in the middle of the rotating plates 491. An adjusting slide plate 493 is slidably connected to the inner surface of the connecting groove 492. A drive column 494 is fixedly connected to the opposite sides of the two adjusting slide plates 493. A straight slot that runs through the left and right is opened in the middle of the lifting sleeve plate 46. The outer surface of the drive column 494 is slidably connected to the inner surface of the straight slot. A third screw 495 is rotatably connected to the middle of the connecting groove 492. The outer surface of the third screw 495 is threadedly connected to the middle of the adjusting slide plate 493. The bottom end of the third screw 495 runs through to the bottom of the rotating plate 491 and is fixedly connected to a knob 496.

[0032] The overall effect of Embodiment 2 is as follows: After the third motor 48 is started, its output shaft drives the rotating plate 491 to rotate, and the driving column 494 moves along the connecting groove 492 of the rotating plate 491. At the same time, through the sliding cooperation with the straight groove of the lifting sleeve plate 46, the circular motion of the rotating plate 491 is converted into the up-and-down reciprocating motion of the lifting sleeve plate 46. Then, the reciprocating sliding column 44 drives the pile driving block 45 to perform high-frequency and continuous hammering on the pile body, ensuring that the pile driving force is uniform and efficient. When the pile body continues to sink, the second motor 32 drives the second screw 33 to rotate, so that the connecting slide plate 41 descends synchronously along the guide column 34, realizing the height adjustment of the pile driving component 4 as the pile body sinks. It can continue to operate without stopping the machine. In addition, rotating the knob 496 drives the third screw 495 to rotate, adjusting the slide plate 493 to slide along the connecting groove 492, changing the movement radius of the driving column 494, thereby flexibly adjusting the lifting stroke of the pile driving block 45. The impact force can be adjusted according to the pile material and construction requirements, which greatly improves the applicability and ease of operation of the equipment.

[0033] The working principle of the entire equipment is as follows: Before construction, the pile body is placed at the designated piling position through the U-shaped connecting groove 11 of the support base 1, ensuring that the top of the pile body is aligned directly below the piling block 45. The first motor 27 of the positioning component 2 is started, and the first screw 28 rotates to make the threaded slider 29 slide. The connecting column 24 is pulled by the pulling rod 25, which drives the rotating arm 22 to rotate around the support frame 21 until the clamping wheels 23 on both sides are tightly attached to the surface of the pile body, thus completing the clamping and positioning of the pile body and preventing the pile body from shaking during the piling process.

[0034] During piling operations, the third motor 48 of the piling assembly 4 is started, and its output shaft drives the rotating plate 491 to rotate. While the drive column 494 moves in the connecting groove 492, it pushes the lifting sleeve 46 to move up and down reciprocally through the sliding engagement with the straight groove of the lifting sleeve 46. In turn, the reciprocating sliding column 44 drives the piling block 45 to continuously strike the top of the pile, gradually driving the pile into the ground. During this process, if it is necessary to adjust the piling force, the knob 496 can be turned, and the third screw 495 rotates to make the adjusting slide plate 493 slide along the connecting groove 492, changing the movement radius of the drive column 494, thereby adjusting the lifting stroke of the piling block 45. The larger the stroke, the stronger the impact force.

[0035] As the pile continues to sink, the second motor 32 of the lifting assembly 3 is activated, and its output shaft drives the second screw 33 to rotate. The connecting slide plate 41 is threaded with the second screw 33 through the threaded hole 42 and slowly descends along the guide column 34, so that the pile driving block 45 always maintains effective contact with the top of the pile, realizing uninterrupted pile driving. At the same time, the clamping wheel 23 of the positioning assembly 2 rotates synchronously with the sinking of the pile, which not only continuously provides clamping force to ensure the verticality of the pile, but also does not hinder the sinking of the pile.

[0036] Once the pile has been driven to the preset depth, the third motor 48, the second motor 32, and the first motor 27 are turned off in sequence. The first motor 27 is then started in reverse to disengage the clamping wheel 23 from the pile, thus completing one pile driving operation. The entire process is efficient, stable, and flexible in operation.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
