As shown in fig. 1, 2, 3 and 4, an automatic drill pipe jacking device for a horizontal directional drilling machine comprises a base 1, a main jacking device 2 installed on the base 1 and a secondary jacking device 5 installed on the main jacking device 2;

the base 1 comprises a bottom plate and a base guide rail vertically fixed on the bottom plate, and the bottom plate is fixed on the vice 11;

the main jacking device 2 is arranged on a base guide rail, a main jacking oil cylinder 3 is arranged between the main jacking device 2 and the bottom plate, the main jacking oil cylinder 3 drives the main jacking device 2 to move up and down on the base guide rail along the vertical direction, and a supporting block 8 and a main jacking guide rail are arranged on the main jacking device 2;

the auxiliary jacking device 5 is installed on the main jacking guide rail, the auxiliary jacking oil cylinder 4 is installed between the auxiliary jacking device 5 and the main jacking device 2, the auxiliary jacking oil cylinder 4 drives the auxiliary jacking device 5 to move up and down on the main jacking guide rail along the vertical direction, the auxiliary jacking device 5 is provided with a telescopic oil cylinder 6 and a telescopic device 7, and the telescopic oil cylinder 6 drives the telescopic device 7 to move along the horizontal direction.

The automatic jacking device is fixed at the front end of a vice 11, two main jacking oil cylinders 3 are symmetrically arranged at two ends of a main jacking device 2, the main jacking device 2 completes all movements before the vice 11 clamps a drill rod 10, firstly, the main jacking device 2 transports an auxiliary jacking device 5 to the highest point, then, the auxiliary jacking device 5 transports a telescopic device 7 to the highest point, then, the telescopic device 7 moves horizontally, the auxiliary jacking device 5 falls back, and the drill rod 10 is controlled at the center of the vice 11.

As an improvement of the embodiment, two main jacking oil cylinders 3 are symmetrically arranged between the main jacking device 2 and the bottom plate, and the main jacking oil cylinders 3 are hinged with the main jacking device 2 and the main jacking oil cylinders 3 are hinged with the bottom plate, so that the use is convenient.
