Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and specifically to a quick positioning pile driving auxiliary device. Background Art

[0002] In building construction projects, foundation treatment is a key link to ensure the stability and safety of buildings. As an important means of foundation treatment, pile driving construction accuracy is crucial.

[0003] Most traditional pile driving positioning methods rely on manual measurement and empirical judgment, resulting in low positioning accuracy and low efficiency. In the construction of complex terrains or large building foundations, it is difficult to accurately grasp the pile positions manually, which easily leads to pile body deviation and pile body inclination, affecting the stability of the overall structure of the building. In addition, some simple positioning auxiliary tools have single functions, cannot meet the requirements of different geological conditions and pile driving equipment, and are easily interfered by external factors during construction, such as environmental impacts like wind force and vibration, further reducing the positioning accuracy. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the existing pile driving positioning method relies on manual work and the positioning accuracy of the auxiliary work is low.

[0005] To solve the above problems, the present invention provides a pile driving auxiliary device capable of improving the pile driving positioning efficiency. The specific solution is as follows: A quick positioning pile driving auxiliary device includes an adjustable support. A first mounting ring is arranged on the adjustable support. A plurality of fastening components are arranged in the middle of the first mounting ring. The outer ends of the fastening components are radially connected with driving racks. The inner ends of the fastening components are rotatably provided with rollers. The axial direction of the rollers is perpendicular to the axial direction of the first mounting ring. The rollers are used for rolling abutting against the pile body. A plurality of driving gears equal in number to the driving racks are rotatably arranged on the first mounting ring. Each driving gear is controlled to rotate synchronously through a driving component. The driving gears are meshed with the driving racks to drive the driving racks to move radially synchronously, so as to drive the fastening components to move inwards or outwards; An attitude sensor is also arranged on the adjustable support to detect the attitude information of the adjustable support and the pile body.

[0006] The present invention adopting the above technical solution, compared with the prior art, has the following beneficial effects: The auxiliary device of the present invention stably supports the pile body through the rollers of the fastening assembly to prevent it from tilting, and the rollers can make the pile body descend smoothly, reducing the friction between the pile body and the auxiliary device; the driving rack can move inwards or outwards under the drive of the driving assembly and the driving gear to change the area enclosed by each fastening assembly to adapt to pile bodies of different diameters; the attitude sensor can quickly detect the inclination angle and position of the adjustable support, so as to judge whether the pile body is tilted or moved, and thus correct it by adjusting the height of each adjustable support or move the auxiliary device as a whole.

[0007] As a preference, a further technical solution of the present invention is: A plurality of the adjustable supports are provided, including a fixed sleeve, a fixed rod and a fixing bolt. Each fixed sleeve is fixedly arranged at the bottom of the first mounting ring at equal intervals. The fixed sleeve sleeves the upper part of the fixed rod, and the fixing bolt is threadedly connected to the side wall of the fixed sleeve. The inner end of the fixing bolt is used to abut against the fixed rod inside the fixed sleeve. Through the above structure, it is convenient to quickly adjust the height of the adjustable support.

[0008] The driving assembly includes a driving motor, a main gear and a driven gear. The main gear is fixedly sleeved on the output shaft of the driving motor. The inner ring and the outer ring of the driven gear are respectively provided with inner teeth and outer teeth. The main gear is meshed and driven with the driven gear through the outer teeth of the driven gear, and the driving gear is meshed and driven with the driven gear through the inner teeth of the driven gear. The driving motor drives the main gear to rotate, synchronously drives the driven gear to rotate through the main gear, and the driven gear drives the driving rack to move, so as to drive the radial movement of each fastening assembly at the inner end of the driving rack.

[0009] The driving motor is fixed at the outer end of one of the adjustable supports. An annular receiving groove is formed in the inner side of the first mounting ring. The driven gear is arranged in the receiving groove. A connecting groove penetrating through the receiving groove is formed in the first mounting ring above the driving motor. The outer circumference of the main gear is located in the connecting groove and is meshed and connected with the driven gear. The driven gear is arranged in the receiving groove, so that the driven gear can rotate in the receiving groove, and the main gear can be meshed with the driven gear through the connecting groove, thereby driving the driven gear to rotate.

[0010] A second mounting ring is arranged on the inner side of the first mounting ring. The first mounting ring and the second mounting ring are coaxially fixed. Each fastening assembly is located in the middle of the second mounting ring. Each driving rack is movably inserted on the first mounting ring and the second mounting ring. The movement stability of the driving rack is increased through the second mounting ring.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The present invention will be further described below in conjunction with embodiments. The purpose is only to better understand the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.

[0016] See the appendix Figures 1-5, an embodiment of the present invention discloses a quick positioning pile driving auxiliary device, including an adjustable bracket. A first mounting ring 110 is arranged on the adjustable bracket. A second mounting ring 111 is coaxially mounted inside the first mounting ring 110. A plurality of fastening components are arranged in the middle of the first mounting ring 110. In this embodiment, four fastening components are provided. The outer ends of each fastening component are radially connected with a driving rack 130. The inner ends of the fastening components are rotatably provided with rollers 135. The axial direction of the roller 135 is perpendicular to the axial direction of the first mounting ring 110. The roller 135 is used for rolling abutting against the pile body. A driving gear 123 with the same number as the driving rack 130 is rotatably arranged on the first mounting ring 110. Each driving gear 123 is controlled to rotate synchronously through a driving component. The driving gear 123 is meshed with the driving rack 130 to drive each driving rack 130 to move radially synchronously, so as to drive each fastening component to move inwards or outwards; An attitude sensor 410 is also arranged on the adjustable bracket to detect the attitude information of the adjustable bracket and the pile body through the attitude sensor 410.

[0017] In this embodiment, four fixing sleeves 310 are installed at the bottom end of the first mounting ring 110. A fixing rod 320 is inserted into any one of the fixing sleeves 310. A threaded hole 340 is formed in any one of the fixing rods 320. A fixing bolt 350 that is in threaded fit with it is installed in any one of the threaded holes 340. The mounting seat 240 is connected to the fixing sleeve 310 close to the driving motor 230. This design can adjust the length of the fixing rod 320 extending out of the fixing sleeve 310 according to the terrain. Then, by installing the fixing bolt 350 into the threaded hole 340, the inner end of the fixing bolt 350 abuts against the fixing rod 320 inside the fixing sleeve 310 to fix the position of the fixing rod 320.

[0018] In this embodiment, four first connecting rods 112 are installed on the first mounting ring 110. The inner end of any one of the first connecting rods 112 is fixedly connected to the second mounting ring 111. Four second connecting rods 121 are installed at one end of the first mounting ring 110 close to the first connecting rod 112. The inner end of any one of the second connecting rods 121 is rotatably connected to a first rotating shaft 122. A driving gear 123 is fixedly sleeved at the bottom end of any one of the first rotating shafts 122. A driven gear 120 is installed in the receiving groove 113. Inner teeth and outer teeth are respectively fixed on the inner side wall and the outer side wall of the driven gear 120. The driving gear 123 meshes with the inner teeth of the driven gear 120. Four sliding grooves 115 are respectively formed in the first mounting ring 110 and the second mounting ring 111. The sliding grooves 115 in the first mounting ring 110 and the second mounting ring 111 are respectively radially corresponding one by one. A driving rack 130 is installed in any group of corresponding sliding grooves 115. An installation block 131 is installed at one end of any one of the driving racks 130 close to the second mounting ring 111. Two mounting plates 132 are installed at the inner end of any one of the installation blocks 131. Bearings 134 are installed at the opposite ends of any group of the mounting plates 132. A second rotating shaft 133 is installed between any group of the bearings 134. A roller 135 is installed on any one of the second rotating shafts 133. A connecting groove 114 is formed at one end of the first mounting ring 110 away from the second mounting ring 111. The connecting groove 114 communicates with the receiving groove 113. The outer circumference of the main gear 210 is located in the connecting groove 114. The main gear 210 meshes with the outer teeth of the driven gear 120. A transmission shaft 220 is coaxially installed at the lower end of the main gear 210. The other end of the transmission shaft 220 is connected to a driving motor 230. A mounting seat 240 is installed at one end of the driving motor 230 away from the transmission shaft 220. The mounting seat 240 is fixed on a fixed sleeve 310. This design can drive the transmission shaft 220 to rotate through the output shaft of the driving motor 230. The transmission shaft 220 drives the driven gear 120 to rotate through the main gear 210. The driven gear 120 then drives four driving gears 123 to rotate. When the driving gears 123 rotate, they drive the four driving racks 130 to move inwards or outwards. When the driving racks 130 move inwards, they drive the installation blocks 131 to move. When the installation blocks 131 move inwards, they drive the rollers 135 to move inwards and support the pile body.

[0019] In this embodiment, a support plate 330 is installed at one end of any one of the fixed rods 320 away from the first mounting ring 110. This design can reduce the pressure generated by the fixed rods 320 on the ground and enhance the adaptability.

[0020] Working principle: During operation, directly move the entire device to the position where piling is required. Subsequently, based on the attitude information of the attitude sensor 410, obtain whether the positions of the adjustable brackets correspond to the positions of the pile hole points. Then, adjust the length of the fixed rod 320 extending out of the fixed sleeve 310 according to the flatness of the location, ensuring the flatness of the first mounting ring 110 to guarantee the perpendicularity of the pile body. Subsequently, start the drive motor 230. The drive motor 230 drives the main gear 210 to rotate through the transmission shaft 220. The main gear 210 drives the driven gear 120 to rotate. When the driven gear 120 rotates, it drives the four drive gears 123 to rotate. When the drive gears 123 rotate, they drive the corresponding drive racks 130 to slide inward. When the drive racks 130 slide inward, they drive the mounting blocks 131 to move inward. When the mounting blocks 131 move, they drive the rollers 135 to roll inward synchronously through the mounting plates 132. When the rollers 135 roll inward, they squeeze and support the pile body. Subsequently, piling is carried out. During the piling process, the rollers 135 rollingly contact the outer wall of the pile body, thus ensuring stable support while preventing the pile body from being damaged by friction with the mounting blocks 131.
