Embodiment Construction
[0039] The present invention will be further described in detail below with reference to the accompanying drawings.
[0040] like figure 1 and figure 2 As shown, it is a screw pile driver disclosed in the present invention, including a crawler chassis 1, a drilling tool 11 and a power head 12, a platform 13 is arranged on the crawler chassis 1, and a main tower arranged in sequence along its length direction is arranged on the platform 13. 14. Hydraulic cylinder 3, first pulley group 15, hoist 16 and support frame 33.
[0041] like image 3 and Figure 4 As mentioned above, the main tower 14 includes a plurality of steel pipes 141 spliced to each other. The operator can adjust the number of the steel pipes 141 according to the actual length of the drilling tool 11. A positioning block 31 and a positioning groove 32 are respectively provided at the opposite ends. When the positioning block 31 is inserted into the positioning groove 32 , the guide rails 143 abut each other,...

The invention relates to a screw pile machine, which is applied in the technical field of screw pile construction equipment, and includes a crawler chassis, a drilling tool and a power head. A platform is arranged on the crawler chassis, and a main tower, a first pulley block and a hoist are arranged on the platform. There is a second pulley block connected to the top of the main tower, and a wire rope is connected to the drum of the winch, and one end of the wire rope goes around the first pulley block and the second pulley block in turn, and then connects with the power head, which is slidably connected to the main tower; The rotating part of the base plate is connected with the base plate, the bottom surface of the base plate is connected with the drive plate, the side wall of the drive plate is connected with a number of limit rods, the bottom surface of the base plate is hinged with the middle rods corresponding to each limit rod, and the limit rods conflict with the middle rods. One end of the middle rod away from the axis of the base plate is connected with a first lug through a traction rope, and the first lug is connected with a second lug through a plurality of extension springs, the second lug is fixed on the base plate, and the traction rope is in a tight state. The invention has the effect of protecting drilling tools.
Description
technical field [0001] The invention relates to the technical field of screw pile construction equipment, in particular to a screw pile driver. Background technique [0002] The screw pile is a kind of "cylindrical upper part and screw type" combined pile, which has been widely used in the field of building pile foundations, and is usually constructed with screw pile drivers.
