Embodiment Construction
[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0018] The present invention consists of a cutting device bracket 2, a cutting mechanism 3 and a cooling device 1. Cutting device support 2 comprises adjustable up and down (for figure 1 For the structure shown, "up and down" refers to "left and right"; other content related to the position of "up and down" are the same) The distance between the central spiral support 2-3 and the one installed on the central spiral support 2-3 are fixed Three cantilever rods of the angle cutting piece cantilever rod 2-1, the first cantilever rod 2-2, and the second cantilever rod 2-4. The bottom of central helical support 2-3 is a cone, is used for central fixing. Cutting piece cantilever bar 2-1 is equipped with cutting mechanism 3, and cutting mechanism 3 comprises drive motor 3-1 and feeding screw mechanism 3-2 and cutting blade 3-3, and first cantilever bar 2-2 is...

Abstract
The invention discloses a cement fly-ash gravel (CFG) pile head cutting device. A cutting blade cantilever rod (2-1), a first cantilever rod (2-2), a second cantilever rod (2-4) and a central spiral support (2-3) are arranged on a bracket (2) of the cutting device; one end of the cutting blade cantilever rod (2-1), one end of the first cantilever rod (2-2) and one end of the second cantilever rod (2-4) are connected with the central spiral support (2-3) respectively; and a cooling device (1) is arranged on the second cantilever rod (2-4). The included angle between the cutting blade cantilever rod (2-1) and the first cantilever rod (2-2) is 120 degrees, and the included angle between the first cantilever rod (2-2) and the second cantilever rod (2-4) is 30 to 120 degrees. A cutting mechanism (3) is arranged on the cutting blade cantilever rod (2-1). Longitudinal central bearing and symmetrical truckle pressed gravity balance are adopted, so the cutting device is safe to use, convenient and fast to assemble and disassemble, and high in working efficiency.
Description
technical field [0001] The invention relates to a special mechanical device for removing pile heads during CFG pile foundation construction. Background technique [0002] In the subgrade construction of railway passenger dedicated lines and high-speed railways, in order to prevent subgrade settlement, a large number of low-grade concrete poured pile foundations, which are mixed with cement, fly ash and crushed stones and water, are installed at the bottom of the subgrade, called CFG piles. According to the design process, after the CFG pile is poured and hardened, the pile head needs to be cut off to reach the specified elevation, so that the pile cap can be poured on it. According to the traditional technology, the pile heads of CFG piles are manually removed, which is time-consuming and labor-intensive, and affects the progress and quality of the project, thus becoming a technical problem that needs to be solved urgently in the construction of CFG piles. [0003] The cutt...
