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

Example Embodiment

[0046] Example 1

[0047] Such as Figure 1 to Figure 5 As shown, the horizontal single-axis directional rotation-impact combination tunneling engineering slotting machine of 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); a hoisting device 24 A symmetrically arranged impact milling device is suspended on the traction end. The impact milling device includes a vertical guide frame 1, a 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 of the guide frame 1, 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 segmented balance and reverse rotation In the milling state, the connecting beam 29 between...

Example Embodiment

[0055] Example 2

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

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

Example Embodiment

[0058] Example 3

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

[0060] Compared with the conventional slotting machine, the present invention has the following advantages:

[0061] 1. The suspended guide frame 1 eliminates the drill rod travel from the ground to the bottom of the groove, and omits the process of connecting the drill rod, which makes the excavating device easy to move, the whole machine is mobile and flexible, and avoids the easy breakage of the rigid double drill rod. , Buried drill and other accidents.

[0062] 2. Single-axis milling is adopted. Compared with double-wheel milling, the thickness of the entire guide frame 1 and the milling device can be further reduced, so that narrower grooves can be cut (narrow grooves with a thickness of only 30cm or less). In many practical pr...

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...
