Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a driven pipe compaction pile machine. Background Technology

[0002] Piling compaction pile machines are widely used in road foundation construction, subgrade reinforcement, foundation treatment of building projects, and pile foundation construction. They are also widely used in the foundation construction of buildings requiring ground reinforcement. The process involves driving cylindrical steel piles into the original foundation to form a hole, or directly pressing precast piles into the foundation soil for pile foundation construction.

[0003] However, existing technologies often encounter challenges during construction due to geological conditions, resulting in high penetration resistance and insufficient pile driving depth. This frequently necessitates the use of pre-drilling equipment to create a pilot hole before driving the pile to compact the borehole. Alternatively, if the pile shrinkage occurs after drilling and the pipe is pulled out, additional drilling equipment is required to clean and enlarge the hole to ensure the correct borehole diameter.

[0004] Since different equipment is used to complete the same pile hole in sequence, it is necessary to change equipment repeatedly, which leads to low construction efficiency, increased construction costs, extended construction period, and easy problems such as pile position deviation and error. Therefore, we propose a driven pipe compaction pile machine. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the existing technology where different equipment are used to complete the same pile hole in sequence, which requires repeated equipment replacement, resulting in low construction efficiency, increased construction costs, extended construction period, and easy pile position deviation and error. In order to solve the technical shortcomings of the existing technology, a driven pipe compaction pile machine is proposed.

[0006] To achieve the above objectives, the present invention adopts the following overall technical solution:

[0007] A driven pipe compaction pile machine, comprising:

[0008] The chassis has a walking track at its bottom, a control box and a mounting frame fixed on its surface, a first cylinder fixed on one side of the top of the mounting frame, a counterweight fixed on one end of the piston rod of the first cylinder, a rotating shaft rotatably connected to the inner wall of the top of the mounting frame and the surface of the chassis, a rotating frame fixed between the two rotating shafts, and mounting slots on both sides of the rotating frame, with clearance slots on the top and both sides of one of the mounting slots.

[0009] A drilling mechanism, which is disposed in one of the mounting slots, is used for drilling operations;

[0010] Two clamping mechanisms are respectively disposed on both sides of another mounting slot for clamping steel pipes;

[0011] A positioning mechanism is provided on one side of the mounting frame and is used to position the rotating frame.

[0012] In one possible design, the drilling mechanism includes a second cylinder and a lifting seat. The second cylinder is fixed on the surface of the rotating frame, and the lifting seat is slidably connected in one of the mounting slots. One end of the piston rod of the second cylinder passes through the rotating frame and is fixed to the lifting seat. A first motor is fixed on the bottom inner wall of the lifting seat, and the output shaft of the first motor passes through the lifting seat and is fixed with a drill rod.

[0013] In one possible design, the clamping mechanism includes a connecting plate fixed to one side of one of the relief grooves. A third cylinder is fixed to the outer wall of one side of the connecting plate. One end of the piston rod of the third cylinder passes through the connecting plate and is fixed to a clamping plate. The clamping plate and the connecting plate are slidably connected. A semi-circular clamping groove is opened on one side of the clamping plate.

[0014] In one possible design, the inner wall of the clamping groove is evenly distributed with multiple spherical grooves, and each of the multiple spherical grooves is provided with a ball bearing.

[0015] In one possible design, the positioning mechanism includes two fourth cylinders, which are respectively fixed on the inner walls of both sides of the mounting frame. A positioning plate is fixed at one end of the piston rod of each fourth cylinder, and the positioning plate cooperates with the rotating frame.

[0016] In one possible design, the positioning mechanism further includes a second motor, which is fixed to the surface of the mounting bracket. One end of the output shaft of the second motor and the outer wall of one of the rotating shafts are both fixed with synchronous pulleys, and the two synchronous pulleys are connected by a synchronous belt drive.

[0017] In one possible design, a counterweight is fixed to the surface of the chassis.

[0018] In this application, during use, the first motor is started to drive the drill rod to rotate, and the second cylinder is started to drive the drill rod to descend and drill a hole in the ground. The drilled hole is two to three centimeters smaller than the steel pipe. After drilling is completed, the drill rod is retracted. Then, the fourth cylinder is started to drive the positioning plate to disengage from the rotating frame. Then, the second motor is started. Under the action of the synchronous pulley and synchronous belt, the second motor drives the rotating frame to rotate. The fourth cylinder is started again to drive the positioning plate to position the rotating frame. Then, the steel pipe is placed between the two clamping slots. The third cylinder is started to drive the clamping plate to move. The clamping plate extends out of the connecting plate and positions the steel pipe. Then, the first cylinder is started to drive the hammer to strike the steel pipe multiple times, gradually sinking the steel pipe into the hole.

[0019] Beneficial effects: In this utility model, the driven pipe compaction pile machine, through the setting of multiple structures such as rotating parts, mounting grooves and clamping plates, after the clamping plates clamp the steel pipe, the steel pipe and the drill rod are symmetrical about the central axis of the rotating shaft. After the rotating frame is flipped, it is ensured that the steel pipe and the drill hole can be aligned in the center, avoiding the situation of offset.

[0020] In this utility model, the driven pipe compaction pile machine, through the setting of ball bearings, ensures the positioning effect of the steel pipe, and at the same time reduces the friction between structures, facilitating the driven pipe operation.

[0021] In this invention, the equipment combines the functions of drilling, pipe driving and compaction, and pressure pile delivery, integrating the functions of different equipment into one, avoiding the need to replace equipment, ensuring pile position deviation, and adopting a walking track for fast movement, thus improving construction efficiency. It is especially suitable for applications requiring pilot hole drilling, hole sweeping, and low headroom. Attached Figure Description
