Description

Technical Field

[0001] This utility model belongs to the field of pile foundation construction technology, and specifically relates to a pile foundation positioning gimbal device. Background Technology

[0002] As the main construction equipment, pile driving machinery lacks a positioning structure for drill rods. Traditional methods result in slow production progress, or the construction site may encounter defects such as reduced diameter, enlarged diameter, mud inclusion, segregation, and short piles due to harsh environmental conditions such as rain and mud. This can lead to issues such as missing piles, needing to re-drive, and poor accuracy. Therefore, it is necessary to improve these methods to address these problems. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a pile foundation positioning gimbal device. An adjustable bracket is installed on a mounting seat on a crossbeam, and an RTK measuring device is bolted to the bracket, providing a support structure for the position adjustment of the RTK measuring device. This ensures that the center of the RTK measuring device is aligned with the center of the drill rod on the drilling rig, allowing for the detection and positioning of the drill rod's position and attitude. This solves the problems of missed piles, difficulty in finding missing pile locations, and difficulty in controlling pile length caused by the lack of pile positioning components in traditional pile driving equipment. By combining the RTK measuring device with the drilling rig, its efficiency and functionality are fully utilized. It provides high-precision position and attitude information for the drilling rig, eliminating the need for pre-layout lines, helping operators better control and navigate the drilling rig, reducing drilling errors and saving time and costs, thus achieving cost reduction and efficiency improvement. The device is simple to install, easy to disassemble, and can be reused in multiple projects, aligning with the development concept of cost reduction and efficiency improvement.

[0004] The technical solution adopted in this utility model is a pile foundation positioning gimbal device, which includes a mounting seat that is adjustable and fixed on the upper crossbeam of the drilling rig. A bracket is adjustable on the upper surface of the mounting seat, and the RTK measuring device is bolted to the bracket. By adjusting the position of the mounting seat and the bracket along the length and width of the crossbeam, the position and attitude information of the drill rod can be detected and positioned when the center of the RTK measuring device is on the same straight line as the center of the drill rod on the drilling rig.

[0005] The mounting base is a channel-shaped plate with its opening facing downwards and adapted to the crossbeam. Multiple tightening bolts are threaded onto one side wall of the mounting base, with their ends pressing against the corresponding side wall of the crossbeam. The mounting base is then fixed to the crossbeam in an adjustable manner along its length by means of the tightening bolts and locking nuts threaded onto the tightening bolts.

[0006] Furthermore, T-shaped guide plates are fixed on both inner walls of the mounting base, and the upper edge of the side wall of the crossbeam is adapted to the guide groove formed by the T-shaped guide plate and the side wall of the mounting base. The end of the tightening bolt extends into the guide groove and abuts against the side wall of the crossbeam.

[0007] Furthermore, the bracket has a Z-shaped structure, and the upper end face of the mounting base has at least two waist-shaped long slots parallel to its width direction. The horizontal plate at the lower end of the bracket is fixed to the mounting base in an adjustable manner by bolts that match the waist-shaped long slots and nuts that match the bolts. The RTK measuring device is fixed to the upper end face of the bracket by bolt connection.

[0008] Furthermore, reinforcing ribs are fixed at the corner positions of the vertical plate and the lower horizontal plate of the bracket.

This solves the problems of missing piles, difficulty in finding missing pile positions, and difficulty in controlling pile length caused by the lack of pile position positioning components in traditional pile driving equipment.

[0020] Pile foundation positioning gimbal device, such as Figure 1-3 As shown, the system includes an adjustable mounting base 3 fixed to the upper crossbeam 1 of the drilling rig 2. A bracket 4 is adjustablely mounted on the upper surface of the mounting base 3, and the RTK measuring device 6 is bolted to the bracket 4. By adjusting the positions of the mounting base 3 and the bracket 4 along the length and width directions of the crossbeam 1, the position and attitude information of the drill rod 5 can be detected and positioned when the center of the RTK measuring device 6 is on the same straight line as the center of the drill rod 5 on the drilling rig 2. In this structure, by setting an adjustable bracket 4 on the adjustable mounting base 3 on the crossbeam 1 and bolting the RTK measuring device 6 to the bracket 4, a support structure is provided for adjusting the position of the RTK measuring device 6. This ensures that the position and attitude information of the drill rod 5 can be detected and positioned when the center of the RTK measuring device 6 is on the same straight line as the center of the drill rod 5 on the drilling rig 2. This solves the problems of missed piles, difficulty in finding missing pile positions, and difficulty in controlling pile length caused by the lack of pile position positioning components in traditional piling equipment.

[0021] By combining the RTK measuring device 6 with the drilling rig, real-time dynamic positioning technology and dual-frequency RTK technology are used to enable the drilling rig to achieve millimeter-level positioning accuracy during the positioning process, which greatly reduces operational errors and can optimize the pile drilling operation process and improve the construction technology.

[0022] The adjustable fixed connection structure between the mounting base 3 and the crossbeam 1 is as follows: The mounting base 3 is a channel-shaped plate with its opening facing downwards and adapted to the crossbeam 1. Multiple tightening bolts 7 are threaded onto one side wall of the mounting base 3, with their ends abutting against the corresponding side walls of the crossbeam 1. The mounting base 3 is adjusted and fixed to the crossbeam 1 along its length direction using the tightening bolts 7 and locking nuts 8 threaded onto the tightening bolts 7. Specifically, T-shaped guide plates 9 are fixed to the inner walls of both sides of the mounting base 3, and the side wall of the crossbeam 1 is adapted to fit into the guide groove 10 formed by the T-shaped guide plate 9 and the side wall of the mounting base 3. The ends of the tightening bolts 7 extend into the guide groove 10 and abut against the side wall of the crossbeam 1. In the above structure, the mounting base 3 is fixed to the crossbeam 1 without damage using the tightening bolts 7 and locking nuts 8, eliminating the need for further processing of the drilling equipment, preventing damage to the drilling equipment structure, ensuring the original structure of the drilling equipment remains unchanged, and simplifying installation and disassembly.

[0023] The specific structure of the bracket 4 is as follows: the bracket 4 has a Z-shaped structure, and the upper end face of the mounting base 3 has at least two waist-shaped long grooves 11 parallel to its width direction. The horizontal plate at the lower end of the bracket 4 is fixed to the mounting base 3 in an adjustable manner by bolts 12 that are adapted to the waist-shaped long grooves 11 and nuts that are adapted to the bolts 12. The RTK measuring device 6 is fixed to the upper end face of the bracket 4 by bolting.

[0024] To improve the strength of the bracket 4, reinforcing ribs 13 are fixed at the corner positions of the vertical plate and the lower horizontal plate of the bracket 4.

[0025] This technical solution integrates the RTK measuring device 6 with the drilling rig, providing high-precision position and attitude information for the drilling equipment. It eliminates the need for pre-layout lines, helping operators better control and navigate the drilling rig, reducing drilling errors and saving time and costs, thus achieving cost reduction and efficiency improvement. It fully utilizes the device's efficiency and functionality, providing high-precision position and attitude information for the drilling equipment. This solution addresses the problems of production delays caused by defects such as reduced pile diameter, enlarged pile diameter, mud inclusion, segregation, and short piles that may occur at pile foundation construction sites. The device is simple to install, freely movable, easy to disassemble, and can be reused in multiple projects, aligning with the development concept of cost reduction and efficiency improvement.

[0026] This structure enables precise positioning of the drill rod, providing conditions for intelligent navigation and pile length control during pile foundation construction using the RTK1+1 system. The entire device is assembled with the drill rod of the drilling rig. After installation, the position of the RTK measuring device 6 is finally adjusted by the position of the mounting seat 3 and the bracket 4 on the top to ensure that the center of the RTK measuring device 6 and the center of the drill rod 5 below are on the same line before drilling can be carried out.
