Construction is a structure that people use all available materials such as soil, stone, wood, steel, glass, reed, plastic, ice, etc.; when piling is required on a construction site, special drilling equipment is generally required, which makes work inconvenient , while increasing the cost of work;

Spiral pile driver is a kind of piling equipment that drives the drill pipe assembly to form holes in the underground drilling machine through the power head. The spiral pile driver can be divided into two parts: the frame and the drill pipe assembly. The hoist and the drill pipe rack are installed on the frame. The drill pipe assembly includes a motor, a reducer, the reducer is connected with the drill pipe, the drill bit is installed at the lower end of the drill pipe, the drill pipe can slide vertically up and down along the slide rail on the drill pipe rack, the steel strand on the winch and the drill pipe assembly item Internal connection, so as to control the lifting of the drill pipe;

However, in the prior art, the upper end of the drill pipe is usually directly connected to the output shaft of the reducer through a coupling, and the moment the drill bit on the drill pipe contacts the ground to drill a hole, a large axial force will be generated, and the hole will be drilled. During the process, the drill pipe is continuously stressed in the axial direction, and the force is directly transmitted to the output shaft of the reducer to produce an impact on the reducer. The seal between the output shaft and the reducer housing is prone to failure, resulting in a decrease in sealing performance, which leads to the failure of the reducer. Oil leakage, which in turn lubricates the internal gears of the reducer, aggravates the wear of the internal gears of the reducer, and ultimately reduces the service life of the reducer.

The drill pipe assembly can easily drill into the rock layer, which ensures the depth of the drill pipe assembly into the rock layer, saves working time, improves work efficiency, and is not easy to damage the drill pipe. The structure is simple and the manufacturing cost is low.

2. In the present invention, when the motor support rises to the uppermost end, the shaft of the damping cylinder contacts and supports the motor support, and the damping cylinder acts as a buffer limit when the motor support rises to the top, which can reduce the impact of the motor support on the drill pipe support. Shock, if during the winding process of the hoist, there is a fault in the hoist and the motor bracket continues to rise after reaching the top, the function of the damping cylinder is very important.

3. In the present invention, the motor bracket is connected to the hook on the pulley through the connecting ring, and the steel cable on the hoist is scaled to control the drill pipe assembly to slide up and down along the slide rail. The wheel is separated from the ground, and then the motor is turned on, and the drill pipe assembly is controlled to drop to the ground through the winch, and piling and drilling are performed. At the same time, the lowering of the steel cable is adjusted through the winch to control the depth of the pile hole. Close, and then control the drill pipe assembly to rise through the hoist to complete piling; during the process of piling holes, the axial force of the drill pipe assembly acts on the motor bracket, while the output shaft of the reducer will not receive force, so that the The reducer plays a protective role, effectively preventing the axial force from being directly transmitted to the reducer, protecting the reducer and improving the overall service life of the equipment.
