[0085] The truss column 210 is fixed on a horizontally extending transverse fixing frame 211, and the transverse fixing frame 211 is installed on the top surface of the frame-type horizontal movable frame 212 below. The frame-type horizontal movable frame 212 is placed on the top surface of the front and rear extending top beam 102 of the left and right auxiliary main beams of the main beam 100 and fixed. It is detachably fixed. Two movable cylinders can be fixed on the outer side wall of the movable main side beam 2121 on one side of the frame-type horizontal movable frame 212. The push rod of the movable cylinder is fixed on the outer side wall of the movable main side beam 2121. The connecting seat of the movable cylinder is detachably fixed (such as bolted) on the top beam 102. The horizontal movement of the frame-type horizontal movable frame 212 can be achieved by retracting the push rod of the movable cylinder. After moving into place, the frame-type horizontal movable frame 212 is fixed by bolts, and the connecting seat of the movable cylinder is fixed After the seat is disassembled, the push rod of the mobile oil cylinder is pushed to move the connecting seat of the mobile oil cylinder to the specified position, and then fixed, and then the bolts at the frame-type horizontal moving frame 212 are removed, and then the push rod of the mobile oil cylinder is retracted to realize the horizontal movement of the frame-type horizontal moving frame 212 to meet the movement needs, and the mobile oil cylinder is provided with a cylinder built-in displacement sensor inside, which can accurately detect the distance pushed out by the push rod of the mobile oil cylinder. When it is pushed to the specified length, the cylinder built-in displacement sensor transmits the sensing signal to the control host, and the control host can control the hydraulic system connected to the mobile oil cylinder, so that the push rod of the mobile oil cylinder is pushed out a certain distance to meet the movement accuracy requirements (the method and structure of installing the cylinder built-in displacement sensor in the cylinder for precise control are existing conventional structures and will not be described in detail here);

[0086] The front and rear left and right parts of the frame-shaped horizontal moving frame 212 are both fixed with an adjusting cylinder 213, and the bottom end of the push rod of the adjusting cylinder 213 is installed with an adjusting pressure block 214, and the bottom surface of the adjusting pressure block 214 is pressed against the top surface of the corresponding top beam 102. The adjusting cylinder 213 is installed with a cylinder built-in displacement sensor 2131, and the top of the cylinder built-in displacement sensor 2131 is fixed at the top of the adjusting cylinder 213.

[0087] Since the adjusting cylinder 213 is provided with a cylinder built-in displacement sensor 2131, when the push rod of the adjusting cylinder 213 is pushed to the corresponding position, the cylinder built-in displacement sensor 2131 senses the position and transmits a signal to the control host (all electrical equipment and electrical equipment in the hydraulic system in this embodiment are electrically connected to the control host through electrical connecting lines, and are controlled and operated by the control host, which will not be described in detail here), and the control host controls the hydraulic system to ensure that the push rod of the adjusting cylinder 213 is pushed out a certain distance (the cylinder built-in displacement sensor 2131 is provided in the adjusting cylinder 213, which is an existing common structure and is a prior art, and will not be described in detail here). The horizontal position of the frame-type horizontal moving frame 212 is adjusted by pushing the push rods of the four adjusting cylinders 213, thereby ensuring the verticality of the pile hammer of the pile driving member and the drill rod of the drilling member installed on the truss column 210, so as to ensure the accuracy of subsequent piling and drilling.
