Cutting type foundation pit expanding excavation device

Abstract

The invention provides a cutting type foundation pit expanding excavation device. The cutting type foundation pit expanding excavation device comprises an excavator arm, a driving oil cylinder, a driving arm, a linkage arm and an installation arm. A cylinder body of the driving oil cylinder is rotationally connected to the excavator arm, a piston of the driving oil cylinder is rotationally connected with one end of the driving arm, the other end of the driving arm is rotationally connected to the excavator arm, one end of the linkage arm is rotationally connected with the driving arm, and the other end of the linkage arm is rotationally connected with the installation arm. One end of the installation arm is rotationally connected with the excavator arm, a cutting device is arranged on the installation arm, the cutting device is rotationally connected with the installation arm, a transposition oil cylinder and a transposition arm are arranged on the installation arm, a cylinder body of the transposition oil cylinder is rotationally connected to the installation arm, a piston of the transposition oil cylinder is rotationally connected with one end of the transposition arm, the other end of the transposition arm is fixed to the cutting device, and a cooling device is installed on the cutting device and comprises a connector, a water pipe and a water tank. The cutting type foundation pit expanding excavation device can adjust the cutting position, depth and angle without moving the excavator, and is more convenient to use.

Description

technical field [0001] The invention relates to the field of excavator equipment, in particular to a cutting type foundation pit expansion device. Background technique [0002] During the excavation of deep foundation pits, excavators carrying different drill bits are used for operations. For example, the existing breaker hammer excavator can bombard the stones with the breaker hammer to achieve the breaking of the stones. [0003] However, in the use of the breaker excavator, the breaker needs to be pressed against the broken object to work. For objects with irregular shapes and halo surfaces, the breaker is difficult to press on the object, so a portable Excavator with cutting knife. [0004] An excavator with a cutting knife can chop objects. Generally, objects need to be cut several times to be completely chopped. The direction and position of each cutting are not exactly the same, so it is necessary to constantly adjust the overall position of the excavator to match th...

[0004] An excavator with a cutting knife can chop objects. Generally, objects need to be cut several times to be completely chopped. The direction and position of each cutting are not exactly the same, so it is necessary to constantly adjust the overall position of the excavator to match the cutting. Knife, inconvenient to use
