Description

Technical Field

[0001] The invention relates to a pile punching machine, in particular to a pile punching machine used in combination with a down-the-hole hammer. Background Art

[0002] The punching pile driver is composed of a pile hammer, a pile frame and auxiliary equipment. The pile hammer is attached between two parallel vertical guide rods (commonly known as gantry) at the front of the pile frame and is lifted by a lifting hook. The pile frame is a steel structure tower frame, and a winch is arranged at the rear thereof to lift the pile and the pile hammer. For example, the Chinese patent announcement number is CN206785374U, an automatic punching system of a punching pile driver, used in the technical field of pile foundation engineering construction, including an automatic control mechanism, a base, a pile hammer, a main rod and a winch arranged on the base, a pulley is arranged on the top of the main rod, and the traction rope led out of the winch is connected to the pile hammer after passing through the pulley. A starting handle and a brake handle for operating the winch are arranged on the base, the lower end of the starting handle is connected to the base through a starting shaft, and the brake handle is connected to the base through a brake shaft. The automatic control mechanism includes a starting cylinder that can drive the starting handle to swing around the starting shaft, a brake cylinder that can drive the brake handle to swing around the brake shaft, and an air source that can control the movement of the starting cylinder and the brake cylinder. This type of punching pile machine only uses a pile hammer to punch holes. When encountering inclined rock in the pile hole, it is necessary to first pour concrete into the pile hole to fill the inclined rock, and then perform the punching operation. This method not only has low construction efficiency, but also because the inclined rock is harder than concrete, when punching again, it is possible that the concrete will be crushed while the inclined rock will still exist.

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] like Figures 1 to 4As shown, a punching pile driver comprises a pile frame 1, a winch 2 and a pile hole forming module; one end of a steel wire 5 on the winch 2 is wound on a drum of the winch 2, and the other end is connected to the pile hole forming module through a guide rod 3 in front of the pile frame 1.

[0025] The pile hole forming module comprises a pile hammer module 4 and a down-the-hole hammer module 8. The two modules are switched and used to perform construction corresponding to different geological layers.

[0026] like Figures 1 to 4 As shown, the down-the-hole hammer module 8 includes a down-the-hole hammer assembly and a platform capable of driving the down-the-hole hammer assembly to rotate. The platform includes a support frame 83, a bearing 85 capable of being mounted on the down-the-hole hammer assembly, and a driving mechanism for driving the down-the-hole hammer assembly. The support frame 83 can be stably placed on the ground and erected on the pile hole. The support frame 83 is used to position the down-the-hole hammer so that the down-the-hole hammer can be coaxial with the pile hole to ensure the normal operation of the down-the-hole hammer. For easy carrying, wheels can be provided on the support frame 83 to move the down-the-hole hammer assembly through the wheels. Figure 5 As shown, the down-the-hole hammer assembly includes a down-the-hole hammer 82 and a drill rod 81 connected to the down-the-hole hammer 82. The drill rod 81 is connected to the inner ring of the bearing 85 through a key. The inner ring of the bearing 85 drives the drill rod 81, and the drill rod 81 drives the down-the-hole hammer 82.
