The utility model sets up a driving mechanism, so that the pile foundation can be placed into the through hole on the sliding plate and the fixed plate, the pile foundation is fixed in the two groups of air rods, the air rods are retracted into the air groove due to the fixation of the pile foundation, the air rods can fix the pile foundation through the pressure generated by the compressed gas, the pile foundation does not deviate in the horizontal direction, and can move up and down relative to the two groups of air rods in the vertical direction. When the pile foundation is fixed, the diesel engine is started, the output shaft of the diesel engine repeatedly extends and retracts, when the output shaft is elongated, the pile driver is driven to hammer the pile foundation downwards, so that the pile foundation moves downwards and sinks into the ground.

[0004] The above device solves the problem that the pile foundation may deviate in the horizontal direction, but still has the following disadvantages:

[0005] When facing different terrain conditions, the above device is difficult to use because there is no fixing measure on the ground, not only is it difficult to maintain balance, resulting in the machine tilting and being unable to vertically drive the pile, but also the machine may deviate from the original position due to the vibration generated by the operation of the machine during pile driving, causing accidents and threatening the safety of surrounding buildings and the personal safety of workers.

DETAILED DESCRIPTION

[0023] Clearly, the described embodiments are merely a part of the embodiments of the present utility model, rather than all the embodiments.

[0024] As Figures 1 to 5 shown, a pile driver for construction engineering, including door frame 1, door frame 1 inside is provided with mobile assembly 2, mobile assembly 2 is provided with pneumatic pile driver 3, door frame 1 bottom surface fixedly connected with balance support assembly 4, balance support assembly 4 includes the connecting plate 401 set up in the both sides of door frame 1 bottom surface, the connecting plate 401 is rotatably connected with support threaded rod 402, support threaded rod 402 bottom surface is provided with support base plate 403, the connecting plate 401 upper and lower sides support threaded rod 402 is rotatably connected with fixed nut 404.

[0025] As Figure 1 shown, the pile driver in the present utility model is similar to the structure of the existing pile driver, and a pile driver for construction engineering is disclosed in Patent No. CN220888642U. The main improvement of the present utility model is that the pile driver can be adjusted parallel to the ground when facing different terrains, ensuring the vertical stability of the pile body and the ground. Figures 1 to 5 As shown, a pile driver for construction engineering in the present utility model, when using, first, pile fixing port two 501 is aligned with the position of the ground to be piled, ensuring the accuracy of the piling position; then, according to the terrain, adjust each balance support assembly 4 on the door frame 1, loosen the fixed nut 404 and move the position of the support threaded rod 402 on the connecting plate 401, tighten the loosened fixed nut 404 after the door frame 1 is horizontal, and fix the bolts on the support base plate 403 to the ground, so that the whole pile driver can be balanced and placed on the ground; then, according to the length of the pile body, control the driving motor 202 to move the moving plate 203 and the pneumatic pile driver 3 upwards, after adjusting to the appropriate height, put the pile body into the pile fixing port two 501, then move the moving plate 203 downwards, so that the pile body enters the pile fixing port one 206, and the pile head 302 is pressed to the top surface of the pile body, completing the fixation of the pile body; before the pile head 302 is pressed, the limiting assembly 6 in the limiting groove one 207 and the limiting groove two 502 will limit the pile body, preventing the pile body of different diameters from shaking between the pile fixing port one 206 and the pile fixing port two 501; during the piling process, as the pile body is gradually driven into the soil by the pneumatic pile driver 3, the threaded groove block 204 and the moving plate 203 will also move downwards under the drive of the driving motor 202, and the pneumatic pile driver 3 will also move downwards with the pile body, thereby ensuring the stability of the piling angle and the piling force, and realizing precise piling of the pile body.

[0026] Figure 2 and Figure 3As shown, the moving component 2 includes a symmetrically arranged moving threaded rod 201, a driving motor 202 arranged at the top of the moving threaded rod 201 and a moving plate 203 arranged between the moving threaded rods 201, the moving plate 203 is a U-shaped structure, and thread groove blocks 204 for rotating the moving threaded rod 201 are arranged on both sides of the moving plate 203, and lifting grooves 101 are provided on both sides of the interior of the gate-shaped frame 1 for fitting the movement of the thread groove blocks 204, the driving motor 202 is located on the top surface of the gate-shaped frame 1, and a rotating mouth 102 for passing the moving threaded rod 201 is provided on the top surface of the gate-shaped frame 1, and a motor housing 103 is provided on the top surface of the gate-shaped frame 1 outside the driving motor 202.

[0027] Specifically, during the piling process, the driving motor 202 will operate at low power to provide a smaller downward pressure on the movable plate 203. As the pile body is gradually driven into the soil by the pneumatic pile driver 3, the threaded groove block 204 and the movable plate 203 will also move downward under the drive of the driving motor 202, and the pneumatic pile driver 3 will also move along with it. Therefore, the pneumatic pile driver 3 will move downward along with the pile body under the drive of the driving motor 202, thereby ensuring the stability of the piling angle and the piling force.

[0028] like Figure 2 and Figure 3 As shown, the pneumatic pile driver 3 includes a pile driver body 301, a pile driving head 302 and an air pump 303 arranged in the pile driver body 301. The pile driver body 301 is arranged in the middle of the upper top surface of the movable plate 203, and the air pump 303 is arranged on one side of the upper top surface of the movable plate 203. The upper portion of the movable plate 203 is provided with a pile driving opening 205 for passing the pile driving head 302, and the lower portion of the movable plate 203 is provided with a pile fixing opening 206 with a diameter larger than that of the pile driving head 302.

[0029] Specifically, with the cooperation of the air pump 303 and the pile driver body 301, the pile driving head 302 will pass through the movable plate 203 to drive the pile body, and the pile body will be placed at the pile fixing port 1 206. The movable plate 203 will provide support for the pile body, making it easier for the pneumatic pile driver 3 to drive the pile body into the ground.

[0030] like Figure 2 and Figure 3 As shown, the lower inner end of the door-shaped frame 1 is fixedly connected to a limiting plate 5 , and a second pile fixing opening 501 corresponding to the first pile fixing opening 206 is opened in the middle of the limiting plate 5 .

[0031] Specifically, with the cooperation of the pile fixing opening 206 and the pile fixing opening 2 501, when piling is required, the pile body can be placed between the pile fixing opening 206 and the pile fixing opening 2 501 by lifting the movable plate 203 upwards, providing support for the placement of the pile body, thereby eliminating the need for manual support, reducing the burden on staff and improving work efficiency.

[0032] like Figure 2 、 Figure 3 and Figure 5 As shown, the movable plate 203 is provided with a limiting groove 1 207 on both sides of the pile fixing opening 1 206, and the limiting plate 5 is provided with a limiting groove 2 502 on both sides of the pile fixing opening 2 501. A limiting assembly 6 is provided in the limiting groove 1 207 and the limiting groove 2 502. The limiting assembly 6 includes a limiting rod 601, a compression spring 602 fixedly connected to the bottom surface of the limiting rod 601, and an arc-shaped limiting block 603 provided on the top surface of the limiting rod 601. The other end of the compression spring 602 is fixedly connected to the bottom surface of the limiting groove 1 207 or the limiting groove 2 502.

[0033] Specifically, by opening limiting grooves at the fixing openings of the movable plate 203 and the limiting plate 5 and setting a limiting assembly 6, after the pile body is placed between the pile fixing opening 1 206 and the pile fixing opening 2 501, it is limited under the elastic force of the compression spring 602, preventing pile bodies of different diameters from shaking between the pile fixing opening 1 206 and the pile fixing opening 2 501, and assisting the pile body to be placed vertically during placement.

[0034] like Figure 5 As shown, a sponge pad 604 is provided on the outer arc surface of the arc-shaped limiting block 603. This arrangement allows the arc-shaped limiting block 603 to fit the surface of the pile body when facing pile bodies of different diameters, thereby increasing the limiting effect.

[0035] like Figure 4 As shown, a reinforcing support plate 405 is provided at the connection between the bottom surface of the supporting threaded rod 402 and the supporting base plate 403. This arrangement can improve the supporting effect and make the structure between the supporting threaded rod 402 and the supporting base plate 403 more stable.

[0036] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein.
