Description

A kind of novel cutting machine

Technical field

The utility model relates to a kind of building foundation engineering auxiliary cutting device, specifically a kind ofly cuts the novel cutting machine that pile crown is used.

Background technology

The foundation engineering of modern project building all need be driven piles, and after stake was driven underground, the requirement for height of basseting was unified as far as possible, and then lays bar-mat reinforcement in the above, carries out follow-up constructing operation.And the stake of laying by piling machine, it is consistent that its height that bassets is difficult to guarantee, and the part of the pile crown after laying all has damage in various degree.In order to guarantee construction quality, the pile crown that bassets will be removed some.All the time, this work all is earlier to cut the cement layer on pile crown top with pneumatic pick or with artificial craft, and then removes the reinforcing bar that exposes with hacksaw or wind cutting mill etc.This mode of operation not only operating efficiency is low, and quality also is difficult to guarantee, operates also dangerous.

The utility model content

The purpose of this utility model just provide a kind of at pile crown, construction is fast, work efficiency is high and the novel cutting machine of handling safety.

The utility model is achieved in that a kind of novel cutting machine, in the frame of foot wheel motor is housed, and driving pulley is housed on the motor shaft head; Front portion in frame is connected to the dead axle frame by support arm, in the dead axle frame central shaft is housed, and the upper end of central shaft is connected to the center belt wheel; The outside at the dead axle frame is connected with revoliving arm, the preceding termination moving axis frame of revoliving arm; In the moving axis frame central shaft is housed, the last termination driven pulley of central shaft, the saw blade of following termination saw carriage and horizontal; Driving belt is connected between driving pulley and center belt wheel and center belt wheel and the driven pulley; The pedestal locking mechanism is housed on frame.

Lay plank earlier near the pile crown in construction site, promote this cutting machine, make it to rely on pile crown, the revoliving arm on the cutting machine is walked around pile crown, and the edge that is connected on the saw blade of moving axis frame central shaft lower end suffers the bottom of pile crown.Closing Switch, starter motor, under the drive of transmission mechanism, saw blade begins to cut pile crown.After cutting to certain depth, open the pedestal locking mechanism, revoliving arm can drive the moving axis frame and turn round around pile crown under the drive of dead axle frame central shaft rotary power, realizes the limit revolution of saw blade, the continuous cutting operation of limit cutting thus.After rotation one week of cutting, can shut down, withdraw from this cutting machine, and then use the hammering pile crown, can take off the pile crown of cutting.

Utilize the utility model to implement the cutting operation of pile crown, realize the mechanized construction of pile crown intercepting, improved work efficiency, shortened the duration, the more important thing is the unification that can guarantee pile crown intercepting back height, for follow-up high-quality construction is laid a good foundation.Use the utility model, can exempt the operation and the use of original pneumatic pick, hacksaw and wind cutting mill etc., and the people is also away from pile crown in cutting process, therefore, the security of pile crown intercept operation is significantly improved.
