Description

TECHNICAL FIELD

[0001] The application relates to the technical field of construction positioning, in particular to a prestressed concrete building pipe pile construction positioning device. BACKGROUND

[0002] The prestressed concrete building pipe pile is a hollow cylindrical pile body formed by pouring concrete and curing after prestressed steel bars (such as high-strength steel wires, steel strands or prestressed threaded steel bars) are tensioned to generate pre-compressive stress before the concrete hardens. The core principle is to use prestress to offset the cracks of the concrete when it is subjected to tension, thereby improving the durability and bearing capacity of the pile body. The prestressed concrete building pipe pile has significantly better crack resistance and bending stiffness than ordinary concrete piles, has a short construction period, is convenient to construct, and is widely used in various projects.

[0003] In the prestressed concrete building pipe pile construction process, accurate positioning and reliable support are key factors to ensure construction quality. However, the traditional construction method has many shortcomings.

[0004] During the pipe pile conveying process of the pile press, the position of the pipe pile needs to be detected manually multiple times. However, this method has obvious hysteresis and cannot timely detect and take measures in the initial stage of pipe pile deviation. Once the pipe pile deviation is not detected in time, the deviation degree may gradually increase as the construction progresses, eventually causing serious construction accidents such as pipe pile fracture and building tilt, causing huge losses to the project, affecting the safety and reliability of the construction, increasing the maintenance cost and safety hazards in the later period, and the traditional method is also relatively complex in the deviation correction process, which requires multiple people to cooperate and has a large adjustment difficulty and low efficiency.

[0059] When pile driver continuously transports pipe pile body 6, multiple sets of positioning plates 33, arc-shaped plates 53 and abutting wheels 45 always contact with the outer wall of pipe pile body 6, when pipe pile body 6 deviates, part of abutting wheels 45 will be extruded by pipe pile body 6, driving adjustment frame 44 to move towards the direction of connecting plate 42, when adjustment frame 44 moves, movable contact piece 46 in adjustment frame 44 contacts with static contact piece 43, so that the alarm gives an alarm, prompting pipe pile body 6 deviates;

[0060] When pipe pile body 6 deviates, the pile driver stops working, and the corresponding electric push rod 32 is started, so that electric push rod 32 drives corresponding positioning plate 33 to move, and pushes pipe pile body 6 to be correct, after being pushed to be correct, static contact piece 43 and movable contact piece 46 are separated, and the alarm is closed, so that the pile pressing work can be continued;

[0061] When pipe pile body 6 needs to be connected after moving downward to be separated from multiple sets of positioning plates 33 under the driving of pile driver, first start two sets of lifting cylinders 34, which push connecting disc 25 to move upward, so that positioning plate 33 moves away from mechanical welding arm 7;

[0062] When the lifting cylinder 34 drives the connecting disc 25 to move upwards, the two groups of auxiliary sliding plates 35 at the bottom of the connecting disc 25 are simultaneously extended from the fixed disc 24, the gear racks on the auxiliary sliding plates 35 simultaneously drive the synchronous gears 81 to rotate, the synchronous gears 81 synchronously drive the synchronous disc 82 to rotate, the synchronous disc 82 drives the driving connecting rod 83 to move away from the synchronous gear 81, when the driving connecting rod 83 moves, the driving connecting rod 83 simultaneously drives the driving frame 84 to move, so that the driving frame 84 drives the two groups of piston rods to move into the double-cylinder piston 85, the air in the double-cylinder piston 85 is extruded to be discharged through the communication pipe 86, and is sprayed on the outer wall of the pipe pile body 6 through the groups of air injection pipes 87, so that the dust and other foreign matters on the outer wall are blown off, and the position to be welded is cleaned in advance.

[0063] At this time, the pile press transports another pipe pile body 6 to the upper side of the positioning plate 33, positions the pipe pile body 6 through the support of the groups of positioning plates 33, and makes the pipe pile body 6 keep stable, the pile press works to press the pipe pile body 6 downwards, so that the two pipe pile bodies 6 gradually approach each other, through the support of the positioning plate 33, the abutting wheel 45 and the arc-shaped plate 53, the two groups of pipe pile bodies 6 can be accurately butted, when the butt joint is completed, the mechanical welding arm 7 is started, the mechanical welding arm 7 rotates along the guide sliding groove 26 in the fixed disc 24, and welds the connection between the two groups of pipe pile bodies 6.
