Technical Field

[0001] The utility model relates to the technical field of loess tower foundation digging, in particular to a defective loess tower foundation digging device. Background Art

[0002] At present, soft foundations such as loess are often encountered in tower foundation construction. Such foundations are prone to settlement and deformation when bearing loads, affecting the stability of the tower foundation. Therefore, such foundations need to be excavated during tower foundation construction.

[0003] Existing excavation devices usually adopt a single mechanical excavation method, such as an excavator. This type of device has a good excavation effect on hard strata, but it is difficult to effectively excavate soft strata such as defective loess. When dealing with defective loess, existing excavation devices and methods have problems such as low excavation accuracy, low excavation efficiency, and easy disturbance to surrounding strata. These problems seriously affect the quality and progress of tower foundation construction. Therefore, we propose a defective loess tower foundation excavation device to solve the above problems.

[0039] The working principle of the above embodiment is:

[0040] (1) When excavating the loess tower base, the positioning mechanism 3 can be controlled by the control system 4, so that the excavating mechanism 5 can be accurately moved to the target position, and the position of the support base 1 can be moved by the universal wheel, and then the insertion rod can be rotated to insert the bottom of the insertion rod into the loess ground, thereby improving the stability of the support base 1, and then the rotating motor 31 is started, and the output shaft of the rotating motor 31 rotates, thereby driving the rotating plate 32 to rotate.

[0041] (2) Then start the No. 2 electric push rod 33, the output shaft of which moves downward, thereby driving the telescopic rod 34 to move downward, so that the support plate 2 drives the excavation mechanism 5 to move downward to the target point, and then start the drive motor 51. The output shaft of the drive motor 51 drives the rotating plate 53 to rotate in the inner cavity of the fixed seat 52. The rotation of the rotating plate 53 can drive the connecting plate 54 and the load-bearing rod 55 to rotate, thereby causing the clamping claw 56 to rotate. At this time, the No. 1 electric push rod 57 can be started, thereby causing the angle of the clamping claw 56 to change. The loess can be excavated by the rotation of the clamping claw 56 and the advancement of the No. 2 electric push rod 33. The scraped loess can be excavated by the cooperation between the No. 1 electric push rod 57 and the clamping claw 56.
