Open pile control device

Abstract

The invention relates to an open pile control device, which comprises a first platform, a pile clamp platform positioned above the first platform, pressing and pulling oil cylinders, a first pile clamp, a second pile clamp, a third pile clamp, pile clamping oil cylinders, pull rods, at least three leveling oil cylinders, leveling bottom plates, and a connecting mechanism, wherein the first pile clamp and the second pile clamp are hinged with the pile clamp platform and are respectively hinged with the third pile clamp through the pull rods, and the pile clamping oil cylinders are hinged with the first pile clamp and the second pile clamp; the first pile clamp and the second pile clamp are pushed by the oil cylinders to rotate around pin shafts of the first pile clamp and the second pile clamp, and drive the third pile clamp to move so as to clamp or loosen a pipe pile, and the leveling bottom plates with the same number of the leveling oil cylinders are positioned below the first platform; piston rods of the leveling oil cylinders are hinged with the leveling bottom plates, and the attitude of the first platform is controlled by adjusting the extension of the leveling oil cylinders; and the connecting mechanism is used for connecting the pile control device with a pile foundation construction host.

Description

technical field [0001] The invention relates to a device for placing and removing piles in pile foundation construction, in particular to a pile guiding pile controller. Background technique [0002] At present, a new type of construction method for large-diameter pipe piles while drilling has emerged: the reaming drill bit is connected to the drill pipe and then penetrates into the inner hole of the prefabricated pipe pile. At the bottom of the pile, the diameter is enlarged and the soil is excavated to form a hole. The diameter of the hole drilled by the reaming drill bit is slightly larger than the outer diameter of the prefabricated pipe pile. After reaching the set depth, the drilling tool is pulled out from the prefabricated pipe pile hole, and the concrete is poured. This kind of construction method has high pile forming efficiency, large bearing capacity, environmental protection, and has great development prospects. [0003] In the existing pile foundation constru...

Problems solved by technology

[0004] However, the adjustment of the existing pile-holding and clamping technology in terms of verticality of pile entry, clamping force, and pile entry speed cannot meet the requirements of the large-diameter drilling-while-drilling and tubular pile construction method on the verticality of pile formation, pile unloading speed, and during construction.
