detailed description

The technical solution provided by the present invention is described in more detail below with reference to FIGS. 1 to 2.

Referring to FIG. 1, an embodiment of the present invention provides a horizontal directional drilling rig, which includes a traveling portion 1, a drill frame 2, a first support portion 3, and a second support portion 4. The drill frame 2 is placed on the running part 1. The first support portion 3 is fixed to a fixed object and is detachably connected to the first end of the drill frame 2. The second support portion 4 is fixed to a fixed object and is detachably connected to the second end of the drill frame 2. The fixed object is, for example, the ground.

The running part 1 is configured as a hydraulic running mechanism, and specifically uses, for example, hydraulic driving to realize its running. The running unit 1 has a crawler structure, for example.

Referring to FIG. 1, the first support portion 3 and the first end of the drill frame 2 are detachably connected, for example, by pins or bolts. The above structure enables quick disassembly of the drill frame 2 and the first support portion 3.

The second support portion 4 is detachably connected to the second end of the drill frame 2 by, for example, a pin or a bolt. The above structure enables quick disassembly of the drill frame 2 and the second support portion 4.

The rig 2 is placed on the walking part 1, and there is no connection relationship between the two. The walking part 1 carries the rig 2. The walking part 1 includes a variable-width boom 12. After the boom 12 is luffed, there is friction between the drill frame 2 and the boom 12, and the two ends of the drill frame 2 are respectively supported by the first support portion 3 and the second support. The parts 4 are connected, so the position of the rig 2 is reliable. Furthermore, with the above structure, after the connection between the drill frame 2 and the first support portion 3 and the second support portion 4 is removed, the walking portion 1 and the drill frame 2 are easily separated.

The above technical solution realizes that there is no connection relationship between the traveling part 1 and the drilling frame 2 of the transportation rig 2, and the traveling part 1 is separated from the drilling frame 2 by the self-walking of the traveling part 1.

Referring to FIG. 1 or FIG. 2, in some embodiments, the horizontal directional drill further includes a power head 5, and the power head 5 is slidably mounted on the drill frame 2.

Referring to FIG. 1 and FIG. 2, the power head 5 is slidably mounted on the drill frame 2, and the power head 5 can be moved from the drill frame 2 to the auxiliary disassembly part 6. The power head 5 can reciprocate on the drill frame 2 to realize the construction operation of a large horizontal directional drill. After the construction is completed, the power head 5 can be moved to the auxiliary disassembly part 6 during disassembly. Separating the drill frame 2 from the auxiliary disassembling portion 6 realizes separation of the drill frame 2 from the power head 5.

In the above technical solution, the entire machine of the horizontal directional drilling machine can be disassembled into five parts: a first support part 3, a second support part 4, a drill frame 2, a power head 5, and an auxiliary disassembly part 6. The walking unit 1 is separate and has no connection relationship with other components. This reduces the weight and overall dimensions of each unit, enabling modular disassembly and transportation.

Referring to FIGS. 1 and 2, in some embodiments, the horizontal directional drilling rig further includes an auxiliary dismounting portion 6. The auxiliary disassembly portion 6 is detachably mounted on the drill frame 2, and the auxiliary disassembly portion 6 is configured so that the power head 5 can be slid from the drill frame 2 to the auxiliary disassembly portion 6.

The auxiliary dismounting part 6 and the drill frame 2 are detachably connected, for example, by a pin or a bolt.

Referring to FIG. 1, in some embodiments, the walking portion 1 includes a chassis 11. The boom 12 is variably provided on the chassis 11, and the drill frame 2 is supported by the boom 12.

In some embodiments, the first support portion 3 includes a ground anchor. The first support portion 3 is fixed to the ground.

In some embodiments, the second support portion 4 includes a hydraulic leg. Through the expansion and contraction of the second support portion 4, the drill frame 2 is separated from the running portion 1.
