Description

Technical Field

[0002] A pile press is generally a pile driving machine that uses static pressure to drive piles into the ground. A hydraulic pile press uses hydraulic pressure as the power. During operation, a hydraulic pile gripper clamps the pile head, and then a pair of pile pressing hydraulic cylinders push the pile gripper to sink the pile. A machine is equipped with several pairs of pile pressing hydraulic cylinders and can press several piles simultaneously. The electrical equipment is used to drive the main pump to operate and the machine to move. It is suitable for driving section steel or I-beams in backfill soil, silt, clay and other sites, and is suitable for urban construction. When the pile press is operating, it does not damage the pile head, the pile body is not bent, there is no noise, no vibration impact, has little impact on the surrounding environment and buildings, and does not damage the land structure, and has been gradually widely used in urban construction in China; The construction steps of static pile pressing mainly include key processes such as measurement and positioning, pile press in place, pile hoisting and inserting, pile body alignment and straightening, static pressure pile sinking, pile splicing, further static pressure pile sinking, pile feeding, termination of pile pressing, and cutting of pile heads. When hoisting and inserting the pile, a supporting crane is generally used for operation. The pile pipe is sent into the gripper by hoisting and forms a butt joint. The connection between the pile pipes generally uses bolt connection or welding connection.

The fitting pieces 402 are arranged at equal intervals on the surface of the pipe clamping and feeding seat 401. The length of the supporting side plate 42 is less than the length of the pipe clamping and feeding seat 401. The two fitting pieces 402 on both sides clamp the pile pipe. And when the pipe clamping and feeding seat 401 moves, it can drive the pile pipe to move. The lifting assembly includes a limit clamp 405 fixedly installed on the top surface of the pipe clamping and feeding seat 401 and a lifting frame 406 fixedly installed on the outer surface of the pipe clamping and feeding seat 401. A lifting groove is opened on the lifting frame 406. A lead screw 407 is arranged inside the lifting groove. A servo motor 408 is fixedly installed on the top of the lifting frame 406. A lifting support plate 409 is arranged between the two lifting frames 406. The two ends of the lifting support plate 409 are respectively threadedly connected to the lead screw 407.

When the pile driving is working, the first pile pipe can be directly sent into the pile clamping mechanism through the crane module, or the pile pipe can be placed on the feeding assembly to transport and feed the pile pipe. During the pressing operation, the pile driving cylinder 31 drives the pile clamping mechanism to move up and down, and the pile pipe can be pressed into the bottom layer. While pressing the pile pipe, the pile pipe can be sent between the two clamping seats 401 in turn through the crane module, and the pile pipe can be sent into the lifting bracket On the plate 409, the limited clamp is adapted to place the pile pipe in a vertical shape, and then the servo motor 408 drives the rotation of the screw rod 407 to move the lifting support plate 409 upward, and the pile pipe is transported upward to facilitate the lifting operation. The bottom of the pile pipe is supported by the hosting side plate 42 to realize the storage of the pile pipe. When a new pile pipe needs to be delivered, the telescopic cylinder 404 is used to drive the clamping seat 401 to move left and right, and the adaptive push cylinder 41 pushes the clamping seat 401 to move forward and backward. The adaptation of the two can simultaneously push the pile pipe to move backward when clamping the pile pipe, and deliver a new pile pipe in the pile clamping mechanism, thereby reducing the downtime during delivery and improving work efficiency.

[0029] Through the above steps, during the pressing operation, the pile pipe is sent into the clamping mechanism, and the pile pipe is clamped and fixed by the clamping mechanism, so that the clamping mechanism is driven downward by the pile pressing cylinder 31 to achieve pressing. At the same time, the pile pipe is hoisted by the crane module and sent into the pipe inlet assembly. Multiple pile pipes can be stored and hoisted while pressing. The time required for loading is reduced and the work efficiency is improved, so as to solve the problem that each loading operation of the pile pipe of the existing municipal construction engineering pile driving equipment is time-consuming and labor-intensive, and the downtime is long, which affects the overall work efficiency.
