Problems solved by technology

However, the inventor has found several problems in the practical research: 1. The above-mentioned slotting machine adopts the milling shaft periodical reversing process to balance the milling reaction force, although it can solve the problem that the rock and soil reaction force drives the whole The frame deviates from the vertical direction, but due to the periodic reversing of the milling axis, it is difficult to take into account the different rotation directions of the cutter teeth on the rotating milling axis. It is difficult to improve the excavation efficiency and increase the wear of the cutter teeth by adopting a reasonable angle and shape. , cutter tooth wear accounts for a large proportion of project cost
On the one hand, this punching method has no pre-applied drilling pressure, and the rock-breaking effect is poor. On the other hand, if the punching intensity is too high, it is easy to damage the excavation parts. The frequency is not high, so the excavation efficiency is greatly limited

Embodiment 1

[0047] like Figure 1 to Figure 5 As shown, the horizontal uniaxial directional rotation-impact combined excavation type engineering slotting machine in this embodiment includes a walking device 25 with a hoisting device 24 and a power system, and a monitoring device (not shown in the figure); the hoisting device 24 A symmetrically arranged impact milling device is hung on the traction end. The impact milling device includes a vertical guide frame 1, a deviation correction device 26, a milling shaft 28 with a milling tool, and an impact device. The impact device is a vertical high-frequency hydraulic impact hammer 6. The axis of the milling shaft 28 is located in the plane where the guide frame 1 is located, and is arranged horizontally; the milling shaft 28 is driven by the vertical hydraulic motor 4 through the reversing device 10, and the milling shaft 28 has a directional rotation of segmental balance and reverse rotation In the milling state, the connecting beam 29 betwee...

Embodiment 2

[0056] The difference between this embodiment and embodiment 1 is that, as Figure 8 and Figure 9 As shown, the impact device is two smaller impact hammers 6 arranged outside the hydraulic motor 4 and its gearbox 12 . The top of the impact hammer 6 is fixedly connected to the middle beam 30 of the guide frame 1 through a buffer device 16, and a vertical beam is provided between the bottom beam 27 of the guide frame 1 and the middle beam 30, and the vertical beams on both sides of the impact hammer 6 A slideway 11 is provided on the top, so that the impact hammer 6 slides up and down along the slideway 11.

[0057] The milling tool is an outwardly protruding cutter tooth base 23, and the cross section of the cutter tooth base 23 is a convex arc surface, and the top of the convex arc surface is inlaid with knife teeth (see Figure 12 and Figure 13 ).

Embodiment 3

[0059] The milling shaft 28 includes a plurality of three-axis symmetrical balance structures combined side by side, and the milling range at the upper end of the inclined milling shaft covers the bottom surface of its support column.

[0060] Compared with the previous slotting machines, the present invention has the following advantages:

[0061] 1. Adopt the suspended guide frame 1, cancel the stroke drill pipe from the ground to the bottom of the groove, and omit the process of connecting the drill pipe, so that the excavation device can be moved conveniently, the whole machine is flexible and flexible, and the breakage that is easy to occur when using rigid double drill pipes is avoided , Burying drilling and other accidents.

[0062] 2. Using single-axis milling, compared with double-wheel milling, the thickness of the entire guide frame 1 and the milling device can be further reduced, so that narrower slots can be drilled (narrow slots with a thickness of less than 30cm...

Abstract

The invention relates to a horizontal single-shaft directional rotation-impact combined excavation type engineering grooving machine which comprises a travelling device provided with winch equipment and a power system and a monitoring device. An impact milling device is hung at the traction end of the winch equipment and comprises a vertical guide frame, a correction device, a milling shaft and an impact device. The axis of the milling shaft is located in the plane where the guide frame is located, and the milling shaft is horizontally or obliquely arranged, is driven by a horizontal hydraulic motor or driven by a vertical hydraulic motor through a reversing device and has a directional rotary milling state of segmental balance reverse rotation. The impact device is arranged in the guide frame. A connecting cross beam above the milling shaft is connected below a guide frame bottom beam through a suspension slide device in a hanging mode. A drill rod of the impact device impacts the connecting cross beam, the milling shaft and a positioning drill bit under hydraulic drive. By adoption of the horizontal single-shaft directional rotation-impact combined excavation type engineering grooving machine, the blade direction and angle can be conditionally selected, and the excavation mode can be rapidly changed according to formation lithology, and high excavation efficiency and reliably are achieved.

Description

technical field [0001] The invention relates to a horizontal uniaxial directional rotation-impact combined excavation engineering slotting machine, which belongs to the technical field of slotting equipment. Background technique [0002] According to the knowledge of the inventor, in engineering fields such as water conservancy, transportation, and construction, it is necessary to build various underground continuous walls under different geological conditions. In the actual construction process, it is a very difficult and unresolved problem to open deep grooves on strata containing gravel, boulders, floating stones and relatively hard rock strata to build various underground continuous walls. The slotting machine developed by the inventor can be used to complete the slotting operation with high efficiency and low cost, and the effect is good. [0003] The inventor applied for a Chinese invention patent (application number 201510173686.9, authorized announcement number CN10...
