Specifically, a groove is provided on the inner wall of the driven gear 23, and a connecting shaft is coaxially fixedly welded to the rear end of the screw rod 22. A convex block is provided on the outer wall of the connecting shaft, and the convex block is adapted to the size of the groove. The convex block has a limiting and guiding effect on the groove, so that the screw rod 22 can rotate synchronously with the driven gear 23, and the rear wall of the sliding rail 21 is rotatably connected to the driving gear 24, and the rotating shaft of the driving gear 24 A stepper motor 25 is coaxially rotatably connected.

The fixing component 4 includes a fixing ring 41. An installation plate 411 is provided on the outer wall of the fixing ring 41. The left and right ends of the installation plate 411 are respectively slidably connected in two slide rails 311. Specifically, pulleys 42 are rotatably connected to the left and right ends of the installation plate 411. The two pulleys 42 are respectively slidably clamped in the two slide rails 311. Convex rings are provided on the left and right end faces of the pulley 42, and the convex rings are respectively clamped on the left and right end faces of the slide rail 311.

Two front-rear through square holes 412 are symmetrically arranged on the front end face of the installation plate 411. Square rods 43 are slidably inserted into the two square holes 412. Ratchet blocks 431 are provided on the rear end faces of the two square rods 43. Spring 1 44 is sleeved on the outer walls of the two square rods 43. The front end of the spring 1 44 abuts against the rear end face of the installation plate 411, and the rear end of the spring 1 44 abuts against the front end face of the ratchet block 431. Specifically, blocking plates are provided at the front ends of the two square rods 43 to prevent the square rods 43 from falling out of the square holes 412. Pulling rings are provided on the front end faces of the two blocking plates. The spring 1 44 provides a backward elastic force for the ratchet block 431.

Specifically, two fixing grooves 312 are symmetrically arranged on the front end face of the installation base plate 31. The two ratchet racks 32 are respectively fixedly installed in the two fixing grooves 312.

[0041] Embodiment 3: Please refer to Figures 4 to 9, A fixing device for foundation piles in construction engineering, which is different from that in Embodiment 1. The guiding component 5 includes a guiding ring 51 and a bottom ring 57. The guiding ring 51 is fixedly installed at the bottom end of the front face of the installation substrate 31 by bolts, and the bottom ring 57 is fixedly installed at the front face of the fixing plate 211 by bolts. Specifically, the bottom ring 57 and the guiding ring 51 are adapted in size. When the device works, the guiding ring 51 and the bottom ring 57 are coaxially connected and the top surface of the bottom ring 57 abuts against the bottom surface of the guiding ring 51. A number of storage boxes 512 are equidistantly arranged in a circle at a position near the bottom end of the outer wall of the guiding ring 51. A number of telescopic claws 55 are slidably installed in the storage boxes 512. A second spring 56 is clamped between the top surfaces of the telescopic claws 55 and the inner bottom surfaces of the storage boxes 512. The top surfaces of the telescopic claws 55 abut against the bottom surface of the foundation pile body 7. Specifically, the telescopic claws 55 are used to prevent the foundation pile body 7 from falling off from the guiding ring 51 during transportation. The bottom surfaces of the telescopic claws 55 are all arc-shaped surfaces. A convex ring is provided at one end of the telescopic claw 55 close to the storage box 512. A blocking ring is provided at the opening of the storage box 512. The blocking ring has a limiting and blocking effect on the convex ring to prevent the telescopic claw 55 from falling off from the storage box 512. A number of pressing plates 571 equal in number to the telescopic claws 55 are equidistantly arranged in a circle on the top surface of the bottom ring 57. The outer wall sizes of the pressing plates 571 are adapted to the inner wall size of the guiding ring 51. The positions of the pressing plates 571 and the telescopic claws 55 correspond one by one. Specifically, when the installation substrate 31 is turned over to be vertically erected, the guiding ring 51 and the bottom ring 57 are coaxially connected, and the pressing plate 571 is inserted into the guiding ring 51. Since the bottom surface of the telescopic claw 55 is an arc-shaped surface, the pressing plate 571 abuts against the bottom surface of the telescopic claw 55, and the telescopic claw 55 compresses the second spring 56 until it completely enters the storage box 512. The bottom end of the foundation pile body 7 loses the supporting force of the telescopic claw 55. Due to the influence of gravity, the foundation pile body 7 slides and is inserted into the bottom ring 57 until the bottom end of the foundation pile body 7 contacts the ground.

[0042] Please refer to Figures 7 to 9, on the outer wall of the guiding ring 51, there are two installation arms 511 symmetrically arranged on the left and right. At the ends of the two installation arms 511, there are roller drums 52 rotatably connected. The rotating shafts of the two roller drums 52 are coaxially connected with reduction motors 54. Specifically, the model of the reduction motor 54 is KPJC-15-K-B1. The two reduction motors 54 are respectively fixedly installed on the outer walls of the two installation arms 511 through bolts. The two reduction motors 54 have a self-locking function. Steel wire ropes 53 are wound around the outer walls of the two roller drums 52. The ramming assembly 6 includes a top ring 61. One end of each of the two steel wire ropes 53 far from the roller drum 52 is fixedly connected to the outer wall of the top ring 61.

A rammer body 63 is coaxially and slidably installed on the top surface of the top ring 61. Specifically, the outer wall size of the rammer body 63 is smaller than or equal to the inner wall size of the limiting ring 612. A rubber ring is adhesively bonded to the bottom surface of the rammer body 63. The rubber ring is used to provide a buffering effect to protect the rammer body 63 from being damaged when it impacts the pile body 7. On the top end of the outer wall of the top ring 61, there are two mounting rings 613 symmetrically arranged on the left and right.

At the same time, lubricating oil is applied between the outer wall of the sliding rod 631 and the inner wall of the sliding cylinder 62. The lubricating oil can reduce the friction between the inner wall of the sliding cylinder 62 and the outer wall of the sliding rod 631, reduce wear, and improve the service life of the device.

The abutment plate 641 is slidably connected in the sliding cylinder, and lubricating oil is applied between the outer wall of the abutment plate 641 and the inner wall of the sliding cylinder. The lubricating oil can reduce the friction between the inner wall of the sliding cylinder and the outer wall of the abutment plate 641, reduce wear, and improve the service life of the device. The outer wall of the telescopic rod 64 is sleeved with a spring three 65. Specifically, a blocking ring is provided at the bottom of the sliding cylinder. The top of the spring three 65 abuts against the bottom surface of the abutment plate 641, and the bottom of the spring three 65 abuts against the top surface of the blocking ring.

The outer wall of the vortex wheel 67 abuts against the top surface of the abutment plate 641. A number of storage cylinders 634 are equidistantly arranged on the circumference of the top surface of the rammer body 63. Caps 69 are threadedly installed on the top surfaces of the storage cylinders 634. Specifically, iron sand is stored in the storage cylinder 634. By opening the cap 69, iron sand of different weights is loaded into the storage cylinder 634, so as to change the weight of the rammer body 63 and indirectly change the hammering force of the rammer body 63.

[0044] The working principle of the present invention is as follows: the staff uses a crane to sequentially insert the foundation pile body 7 into the guide assembly 5, the fixing assembly 4, and the compacting assembly 6 from front to back, and the steel wire ropes 53 in the two rollers 52 are stretched and kept in a taut state, so that the top ring 61 of the compacting assembly 6 is fixedly installed at the end of the foundation pile body 7, so that the foundation pile body 7 is installed on the transport vehicle body 1, and a ground breaking cone is welded on one end face of the foundation pile body 7 close to the guide assembly 5, so as to facilitate the subsequent ground breaking operation, and the foundation pile body 7 is accurately transported to the designated location by the transport vehicle body 1;

[0045] When the lifting component 2 is working, it causes the installation substrate 31 to flip at the end of the fixed plate 211. First, the installation substrate 31 is flipped by a certain angle through two second hydraulic rods 28, thereby reducing the working pressure of the first hydraulic rod 27. At the same time, the first hydraulic rod 27 is started to lift the installation substrate 31, causing the installation substrate 31 to flip on the fixed plate 211. During this process, the stepping motor 25 is started to drive the active gear 24 to rotate. The active gear 24 drives the driven gear 23 and the screw 22 to rotate synchronously. The screw 22 drives the sliding block 26 to move forward in the sliding rail 21 until the installation substrate 31 is vertically erected. At this time, the first hydraulic rod 27, the installation substrate 31, and the sliding rail 21 form a stable triangular structure to provide a stable support for the pile body 7;

[0046] The guiding component 5 pulls the top ring 61 at the top of the pile body 7 through two steel wire ropes 53. Two reduction motors 54 control the rotation of two rollers 52, so that the two steel wire ropes 53 between the guiding ring 51 and the top ring 61 are always kept in a taut state, thereby ensuring that both the top and bottom ends of the pile body 7 maintain the correct vertical direction during the descending process and avoiding deviation. The telescopic claw 55 is slidably installed in the storage box 512 on the outer wall of the guiding ring 51. The top surface of the telescopic claw 55 abuts against the bottom end of the pile body 7 to prevent the pile body 7 from falling off during transportation;

[0047] After the installation substrate 31 is vertically flipped, the guiding ring 51 is coaxially connected to the bottom ring 57. The pressing plate 571 on the bottom ring 57 enters the inside of the guiding ring 51 and pushes the telescopic claw 55 to retract into the storage box 512. The bottom end of the pile body 7 loses the supporting force of the telescopic claw 55. The pile body 7 is released and affected by gravity. The pile body 7 is slidably inserted into the bottom ring 57 until the bottom end of the pile body 7 contacts the ground, realizing precise positioning;

[0048] The ramming component 6 is used to ram the pile body 7. The ramming component 6 is installed at the top of the pile body 7 through the top ring 61. The outer wall of the top ring 61 is connected to the guiding ring 51 through two steel wire ropes 53. The two reduction motors 54 have a self-locking function. The two reduction motors 54 drive the two rollers 52 to rotate, so that the two steel wire ropes 53 are always kept in a taut state, making the top ring 61 always fixed at the top of the pile body 7. A limiting ring 612 is provided on the inner wall of the top ring 61. The bottom surface of the limiting ring 612 abuts against the top surface of the pile body 7. The rammer body 63 is slidably installed in the top ring 61. The sliding rod 631 is inserted into the sliding cylinder 62 and is prevented from falling off through the blocking ring to ensure the stability of the ramming movement. A number of storage cylinders 634 are provided in the rammer body 63 to store iron sand of different weights. The weight of the rammer can be controlled by adjusting the amount of iron sand, changing the ramming force, and adapting to different construction requirements;

[0049] Start the brushless motor 68 to drive the rotating rod 66 to rotate. The rotating rod 66 drives the spiral wheel 67 to rotate. The outer wall of the spiral wheel 67 abuts against the abutting plate 641. When the spiral wheel 67 rotates, it drives the telescopic rod 64 to move downward, and the third spring 65 is compressed. Since the end of the telescopic rod 64 abuts against the top of the pile body 7, the rammer body 63 is continuously lifted in the top ring 61 until the outer wall of the maximum outer diameter of the spiral wheel 67 is disengaged from the abutting plate 641. At this time, the top surface of the abutting plate 641 drops to abut against the outer wall of the minimum outer diameter of the spiral wheel 67. At this time, the third spring 65 provides a restoring force to retract the telescopic rod 64 into the sliding cylinder. During this process, due to inertia, the rammer body 63 still stays in mid-air. Due to the lack of the supporting force of the telescopic rod 64, the rammer body 63 falls under the influence of gravity and impacts the top of the pile body 7. The bottom surface of the rammer body 63 provides a buffering effect through the rubber ring to protect the rammer body 63 from damage when it impacts the pile body 7. The brushless motor 68 keeps working, and this process repeats. The rammer body 63 continuously impacts the top of the pile body 7 until the pile body 7 sinks into the soil;

[0050] When the pile body 7 gradually enters the soil, the height of the tamping assembly 6 at the top of the pile body 7 continuously decreases. When the tamping assembly 6 contacts the fixing assembly 4, when the fixing ring 41 is subjected to a downward pressure, the ratchet block 431 compresses the first spring 44 and disengages from the ratchet rack 32, enabling the fixing assembly 4 to move downward within the two slide rails 311; thus, the operation of this device is completed.

[0051] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
