Description
Technical Field
The invention relates to the technical field of building pile foundation construction devices, in particular to a precise cutting device for a CFG pile head.
Background
The CFG pile is formed by mixing cement, broken stone, sand, fly ash and water. The CFG pile can use the industrial waste fly ash and stone dust as the admixture, so the construction cost is low, the CFG pile is widely used in the process of treating and constructing a building foundation, the construction quantity of the CFG pile is large, and the cutting efficiency and the quality of the pile head become construction problems.
At present, two common methods for cutting the pile head of the CFG pile in the prior art are as follows: a manual pile cutting method includes such steps as cutting piles by a hand-held cutter, cutting by about 5cm, symmetrically arranging 2 or 4 steel bars on the same horizontal plane at same angle, and beating to cut pile heads. After cutting, the pile top is flattened from the periphery to the middle by using a steel drill and a hand hammer until the designed elevation of the pile top is reached. The other is a manual auxiliary mechanical pile cutting method, wherein a two-wheel cutting machine is adopted to perform three-cutter circular cutting, and the number of the circular cutters can be properly increased according to actual conditions. After the circular cutting pile is completed, if the uneven phenomenon exists at the part which is not cut in the middle of the pile body, the pile body is manually trimmed to the designed pile top elevation.
The manual truncation method has the following drawbacks: (1) Placing steel drills along the circumferential cuts of the piles, and simultaneously beating the steel drills by using a large hammer to cut off the pile heads, wherein the cutting effect is low, and the risk that shallow pile breakage occurs in the pile body due to pile beating exists; (2) The cut piles have the problems of fracture, fracture inclined planes, poor flatness and the like on the top surfaces, secondary treatment is needed, pile splicing treatment is needed for severe damage, and cost is increased.
The auxiliary mechanical pile cutting method also has the following defects: (1) The manual auxiliary mechanical cutting is performed, most of the existing cutting equipment is a two-wheel trolley hand-held cutting machine, the cutting is performed by adopting a three-cutter or four-cutter cutting method, and the balance between the front and the rear of the two-wheel trolley is difficult to maintain by manual hand pushing; (2) the trolley with uneven and non-compact ground can incline. (3) The phenomenon of inclined plane, staggered platform or two layers of skin easily appears on the pile top after pile cutting, which is labor-consuming and time-consuming and increases the work load of the soil engineering.
How to accurately and efficiently complete the cutting of the pile head of the CFG pile is a technical problem to be solved.
Disclosure of Invention
The invention aims to solve the technical problem of providing the accurate cutting device for the CFG pile head, which is simple and convenient to operate and high in cutting precision.
The technical scheme adopted for solving the technical problems is as follows: the utility model provides a accurate cutting device of CFG stake pile head, includes the frame, it has the horizontal control grillage that can rise and fall to hang in the frame horizontal control grillage left and right sides roll respectively and are connected with the cutting mechanism that can control reciprocating motion, cutting mechanism includes through gyro wheel roll connection motor support on the horizontal control grillage, installs driving motor on the motor support and the cutting knife wheel of being connected with the driving motor transmission.
Further, a hand pushing plate which is convenient for pushing the motor bracket to reciprocate left and right by hand is arranged on the motor bracket.
Further, the horizontal control plate frame and the hand pushing plate are provided with magnetic level bars.
Further, four electric hoists connected with the horizontal control plate frame are respectively arranged at the top of the frame.
Further, the device also comprises a cooling water tank arranged at the top of the frame, and the cooling water tank is connected with a cooling water pipe and provided with a control water valve.
Further, the cutting knife wheel is rotationally connected with the motor bracket through a knife wheel rotating shaft, and an output shaft of the driving motor is connected with the knife wheel rotating shaft through belt transmission.
The beneficial effects are that: in this accurate cutting device of CFG stake pile head, make the cutting knife wheel of left and right sides be in same horizontal axis with the CFG stake through adjusting horizontal control grillage, the cutting knife wheel pair CFG stake of successively driving both sides respectively cuts, because through horizontal control grillage adjustment two cutting knife wheel's position, avoid the cutting knife wheel to appear more disjunctor faces after cutting because of deviating from horizontal axis, guarantee pile bolck cutting smoothness, overcome the phenomenon that pile bolck easily appears inclined plane, wrong platform or two-layer skin among the prior art after cutting.
