All other implementations obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0018] The utility model provides an auxiliary support device for a pile driver, such as Figure 1 - Figure 4 As shown, it includes a pile driving mechanism 1 and two U-shaped plates 2. The pile driving mechanism 1 includes a pile driver body 101 and a clamping nozzle 102 installed on the pile driver body 101. A pile driving body 103 is fixedly installed on the surface of the clamping nozzle 102.

[0019] Both ends of the two U-shaped plates 2 are fixedly connected with mounting components 5, and the two U-shaped plates 2 are fixedly connected through the mounting components 5.

The outsides of the two U-shaped plates 2 are fixedly connected with connecting components 3. The U-shaped plates 2 are fixedly installed on the construction ground through the connecting components 3. Support components 6 are provided at the corners of the inner walls of the U-shaped plates 2. When in use, when the pile driver main body 101 performs piling construction on the combined piles, the supporting components 6, the pushing components 7 and the mounting components 5 cooperate with each other to provide auxiliary support for the piling body 103, thereby reducing the shaking amplitude of the piling body 103 during piling due to the shallow depth of piling and the soft soil for piling, thereby ensuring the piling effect of the combined piles.

[0020] Furthermore, the support assembly 6 includes a fixed plate 601, the side surfaces of the fixed plate 601 are fixedly connected to the corners of the inner wall of the U-shaped plate 2, a V-shaped block 602 is provided on the side of the fixed plate 601 away from the U-shaped plate 2, and the side of the V-shaped block 602 away from the fixed plate 601 is slidably engaged at the corners of the piling body 103, two pushing assemblies 7 are provided between the fixed plate 601 and the V-shaped block 602, and the fixed plate 601 and the V-shaped block 602 are movably connected via the pushing assembly 7.

[0021] Furthermore, the pushing assembly 7 includes a sleeve 701, one end of the sleeve 701 away from the V-shaped block 602 is fixedly connected to the surface of the fixed plate 601, the inner wall of the sleeve 701 is slidably connected with a sliding rod 702, and one end of the sliding rod 702 away from the sleeve 701 is fixedly connected to the surface of the V-shaped block 602, and the outer side of the pushing assembly 7 is slidably connected with a spring 703, and the two ends of the spring 703 are respectively fixedly connected to the surface of the fixed plate 601 and the surface of the V-shaped block 602. When in use, during the installation and connection of the U-shaped plate 2, the V-shaped block 602 is abutted against the corner of the pile driving body 103, pushing the V-shaped block 602 to move toward the fixed plate 601. During the movement, each sliding rod 702 is pushed to slide on each sleeve 701 respectively and drive the spring 703 to deform under force to generate elastic force. Through the elastic force of each spring 703, the V-shaped block 602 is pushed to keep against the corner of the pile driving body 103.

[0022] Furthermore, the mounting assembly 5 includes mounting plates 501, and the mounting plates 501 are fixedly connected to both ends of the U-shaped plate 2. Bolts 502 are provided at both ends of the U-shaped plate 2. The mounting plates 501 at the same end of the two U-shaped plates 2 are fixedly connected by the bolts 502. When in use, the mounting plates 501 at both ends of the two U-shaped plates 2 are connected by the bolts 502, so that the two U-shaped plates 2 are installed and connected together and sleeved on the outside of the piling body 103.

[0023] Furthermore, the connecting component 3 includes a Z-shaped plate 301 fixed on the side of the U-shaped plate 2, and the lower surface of the Z-shaped plate 301 away from the end of the U-shaped plate 2 is movably connected with a conical rod 302, and the upper surface of the Z-shaped plate 301 away from the end of the U-shaped plate 2 is installed with a driving component 4. When in use, the conical rod 302 is driven downward by the driving component 4. During the downward movement of the conical rod 302, the conical rod 302 is inserted into the construction ground, so as to connect and fix the two installed U-shaped plates 2.

[0024] Furthermore, the driving assembly 4 includes a threaded sleeve 401 fixed on the upper surface of one end of the Z-shaped plate 301 away from the U-shaped plate 2, the interior of the threaded sleeve 401 is threadedly connected with a threaded rod 402, the bottom end of the threaded rod 402 is fixedly connected to the top of the conical rod 302, and the top of the threaded rod 402 is fixedly connected with a driving disk 403. When in use, the threaded rod 402 is driven to rotate by the driving disk 403. During the rotation of the threaded rod 402, the conical rod 302 is driven downward by the mutual threaded transmission between the threaded rod 402 and the threaded sleeve 401.

[0025] The working principle of the utility model is as follows: when the pile driver body 101 is used to drive the combined pile, one end of the pile driving body 103 is fixed on the clamping nozzle 102. After the fixation is completed, the pile driver body 101 drives the pile driving body 103 to drive the combined pile;

During the installation and connection process, the V-shaped block 602 is against the corner of the piling body 103, pushing the V-shaped block 602 to move toward the fixed plate 601. During the movement, each slide bar 702 is pushed to slide in each sleeve 701 and drive the spring 703 to deform and generate elastic force. Through the elastic force of each spring 703, the V-shaped block 602 is pushed to keep against the corner of the piling body 103, thereby improving the stability of the device.

[0027] After the two U-shaped plates 2 are installed, the threaded rod 402 is driven to rotate by the driving disk 403. During the rotation of the threaded rod 402, the threaded rod 402 and the threaded sleeve 401 are mutually threadedly transmitted, so that the threaded rod 402 drives the tapered rod 302 to move downward, thereby inserting the tapered rod 302 into the construction ground, so that the two installed U-shaped plates 2 are connected and fixed. Through the connection and fixing effect of the two U-shaped plates 2 and the offset effect of the V-shaped blocks 602 at the four corners of the piling body 103, the piling body 103 is auxiliary supported, thereby reducing the shaking amplitude of the piling body 103 caused by the shallow depth of piling and the relatively soft piling soil, which is beneficial to improving the piling effect of the combined pile.
