Description

Technical Field

[0001] The utility model relates to the technical field of retaining wall slotting machine equipment, in particular to a retaining wall hole forming drill with a horizontal boss. Background Art

[0002] In slope support, roadbed construction and other projects, retaining walls are the most effective measures to transfer the lateral thrust of rock and soil to the stable stratum below the sliding surface, resist the lateral thrust, and control engineering and geological disasters. They are widely used in various engineering fields. The cross-section of traditional retaining walls is large, and the strength of the rock and soil in front of the retaining wall cannot be fully utilized. For retaining walls with horizontal cantilever plate structures, the horizontal cantilever plate can fully utilize the strength of the rock and soil in front of the retaining wall and improve the anti-sliding ability of the retaining wall. However, it is extremely difficult to make holes in the horizontal cantilever plate of the retaining wall with horizontal cantilever plate. Traditional retaining wall holes are usually excavated manually and mechanically. The collapse caused by manual bored pile construction accounts for 65% of the total collapse accidents, and the efficiency is low and the cost is high. Mechanical excavation is safer and more efficient. Therefore, the use of mechanical drilling and excavation of retaining wall holes with horizontal cantilever plates in the rock and soil layer is of great significance to ensure the safety of construction personnel and improve efficiency.

[0003] Existing slotting technologies mainly include bucket type and milling wheel type. Patent No. CN 114687393A "A continuous wall construction equipment and construction method" uses a rotary drill and grab bucket to circulate and drill underground continuous wall grooves. Patent No. CN 110258693A "A hydraulic grab bucket and underground continuous wall construction equipment" uses active buckles and connectors to switch between hydraulic grab buckets and double-wheel milling, achieving multiple uses of one machine to drill underground continuous wall grooves. In order to realize the construction of ground-connected walls in low clearance, patent number CN 114086618A "A modular milling slot device for underground ground-connected wall construction" modularizes the functional components of the ground-connected wall slotting equipment into milling modules, slurry extraction modules, winding modules and accessory reel modules, and connects them from front to back and lays them on the track; patent number CN115070953A "A slotting equipment for underground continuous wall construction in construction projects" installs the synchronous milling and hydraulic cutting equipment between two carrying vehicles through a frame to prevent the slot hole caused by the carrying vehicle from collapsing due to lateral pressure, thereby improving the slotting quality and slot hole stability. Patent No. CN 216108696 U "A Truss Chain Milling and Mixing Ground Wall Machine" and Patent No. CN 115897551 A "A Continuous Wall Construction Equipment and Construction Method Based on TRD Drilling Rig" both set a chain with multiple milling heads evenly distributed on the trusses with active and passive drive mechanisms at both ends, and drive the chain with milling heads to drill the ground wall slots through the active drive mechanism. Although the existing ground wall slotting machine has solved some ground wall slotting problems, the following problems still exist: (1) The soil pressure on the inner side of the retaining wall will cause the contact position between the retaining wall and the embedded section to bulge; (2) The strength of the rock and soil of the embedded section of the retaining wall cannot be fully utilized to resist the deformation of the retaining wall caused by the soil pressure; (3) The anchoring depth of the retaining wall is too large, resulting in excessively high construction costs; (4) It is impossible to realize the construction of horizontal cantilever plate structure holes in the rock and soil. Summary of the invention

[0004] The purpose of the utility model is to provide a retaining wall hole-forming drill with a horizontal boss in accordance with the above-mentioned deficiencies of the prior art, which is composed of an orthogonal crawler drill assembly and a cross-cutting crawler drill. Vertical wall holes are drilled in the rock and soil body by the orthogonal crawler drill assembly and the cross-cutting crawler drill, and horizontal boss holes are drilled in the rock and soil body by the orthogonal crawler drill assembly. The horizontal boss can make full use of the strength of the rock and soil body in front of the retaining wall to improve the anti-slip ability of the retaining wall; reduce the anchoring length of the retaining wall and save construction costs; the drilling of the horizontal boss hole does not require the assistance of other mechanical equipment, which saves construction period and construction costs, improves work efficiency, and ensures project quality and the safety of construction personnel.

[0028] The following is a further detailed description of the features of the present invention and other related features through embodiments in conjunction with the accompanying drawings to facilitate understanding by technicians in the same industry:

[0029] Example: Figures 1 to 4As shown, the present embodiment relates to a retaining wall hole-forming drill with a horizontal boss, which mainly comprises a U-shaped steel frame 3, a lifting assembly 4, an orthogonal crawler drill assembly 1 and a cross-cutting crawler drill 2. The lifting assembly 4 is used to lift the U-shaped steel frame 3. The orthogonal crawler drill assembly 1 and the cross-cutting crawler drill 2 are both installed on the U-shaped steel frame 3, and the orthogonal crawler drill assembly 1 is horizontally arranged, and the cross-cutting crawler drill 2 is vertically arranged. The bottom of the orthogonal crawler drill assembly 1 and the bottom and side of the cross-cutting crawler drill 2 are all exposed outside the bottom of the U-shaped steel frame 3. The bottom surfaces of the orthogonal crawler drill assembly 1 and the cross-cutting crawler drill 2 are flush with each other, and are used to drill vertical wall holes in the rock and soil to form a vertical retaining wall. The orthogonal crawler drill assembly 1 can be moved horizontally, that is, the horizontal direction of the orthogonal crawler drill assembly 1 can be moved outside the U-shaped steel frame 3, and is used to drill horizontal boss holes in the rock and soil to form a horizontal boss.

[0030] like Figures 1 to 4 As shown, the U-shaped steel frame 3 is composed of a left guard plate 31, a right guard plate 32 and a front guard plate 33, and a drill hole 34 is provided on the right guard plate 32 to allow the orthogonal crawler drill assembly 1 (orthogonal crawler drill 11) to pass through. The lifting assembly 4 includes a cable fixing frame 41, a hanging beam 42, a cable motor 43 and a cable 45. The cable fixing frame 41 is fixed to the bottom surface of the hanging beam 42, and the cable motor 43 is fixed to the hanging beam 42 via the cable motor shaft 44 thereon. The cable motor 43 is used to drive the cable 45 and the U-shaped steel frame 3 hoisted at its lower end to perform lifting and lowering movements to ensure the normal operation of the orthogonal crawler drill assembly 1 and the cross-cutting crawler drill 2. Among them, the cable 45 is connected to the left guard plate 31 and the right guard plate 32 of the U-shaped steel frame 3 respectively.

[0031] like Figures 1 to 4As shown, the orthogonal crawler drill assembly 1 includes an orthogonal crawler drill 11 and a translation assembly 12. The translation assembly 12 drives the orthogonal crawler drill 11 to move horizontally, that is, the translation assembly 12 drives the orthogonal crawler drill 11 to move through the drill opening 34 to the outside of the U-shaped steel frame 3 to drill a horizontal boss hole in the rock and soil. The orthogonal crawler drill 11 includes a rotating motor assembly 111, a crawler assembly 112 and a connecting plate 113. The rotating motor assembly 111 is composed of a rotating motor rotor 1111 and a gear ring 1113. Two gear rings 1113 are relatively arranged on the left and right, and the rotating motor rotor 1111 is fixed on the inner ring of the gear ring 1113. Two connecting plates 113 are relatively arranged on the front and back, and the two ends of the connecting plates 113 are respectively fixedly connected to the same end of the rotating motor fixed shaft 1112 of the two rotating motor rotors 1111. The connecting plate 113 is provided with an axial hole 122 corresponding to the rotating motor fixed shaft 1112, and the gear ring 1113 is provided with a plurality of teeth 1114 along the circumference of its outer ring. The crawler assembly 112 includes a crawler 1121 and a reamer assembly 1122. The crawler 1121 is annular and is provided with a plurality of teeth 114 along the circumference of its inner ring. The teeth 114 on the crawler 1121 mesh with the teeth 114 on the outer ring of the gear ring 1113. The reamer assembly 1122 is evenly arranged along the circumference of the outer ring of the crawler 1121. The reamer assembly 1122 includes a reamer base 11221 and a reamer 11222 obliquely mounted on the reamer base 11221. The rotating motor rotor 1111 drives the gear ring 1113 to rotate, so as to drive the crawler 1121 to rotate, thereby driving the reamer 11222 of the reamer assembly 1122 to reamer the rock and soil. The inclined arrangement of the reamer 11222 is more conducive to reamer excavation of the rock and soil.

[0032] like Figures 1 to 4 As shown, the translation assembly 12 includes a U-shaped driving frame 121, a translation motor 124, a sliding block 125 and a support seat 126. The support seat 126 and the translation motor 124 are respectively fixed on the two sides of the U-shaped steel frame 3 (the left guard plate 31 and the right guard plate 32). The translation screw 123 on the translation motor 124 is rotatably connected to the support seat 126. The sliding block 125 cooperates with the translation screw 123 and is installed on the translation screw 123. The sliding block 125 is fixed on the middle part of the U-shaped driving frame 121. The two ends of the U-shaped driving frame 121 are respectively fixedly connected to the two ends of a rotating motor fixed shaft 1112. Both ends of the U-shaped driving frame 121 are provided with an axial hole 122 corresponding to the rotating motor fixed shaft 1112. The translation motor 124 drives the translation screw 123 to rotate, so as to drive the sliding block 125 to move along the length direction of the translation screw 123, thereby realizing the horizontal movement of the orthogonal crawler drill 11.

[0033] In this embodiment, except that the cross-cutting track drill 2 is vertically arranged, and the two ends of the fixed shaft 1112 of the rotating motor of the cross-cutting track drill 2 are respectively fixedly connected to the left guard plate 31 and the right guard plate 32 of the U-shaped steel frame 3 (the connecting plate 113 is not provided), the remaining structures of the cross-cutting track drill 2 are the same as those of the orthogonal track drill 11, so they are not repeated here.

[0034] The beneficial technical effects of this embodiment are:

[0035] (1) Drilling horizontal boss holes in rock and soil by using an orthogonal crawler drill assembly;

[0036] (2) The horizontal boss can fully utilize the strength of the rock and soil in the embedded section of the retaining wall to resist the deformation of the retaining wall caused by soil pressure;

[0037] (3) The horizontal boss can eliminate the uplift at the contact point between the retaining wall and the embedded section caused by the soil pressure inside the retaining wall;

[0038] (4) Reduce the anchorage length of the retaining wall and save construction costs;

[0039] (5) Vertical walls and horizontal bosses in rock and soil bodies can be drilled in one go, which improves construction efficiency and saves construction and equipment costs.

[0040] Although the above embodiments have described the concepts and embodiments of the purpose of the utility model in detail with reference to the accompanying drawings, ordinary technicians in this field can recognize that various improvements and modifications can still be made to the utility model without departing from the scope of the claims, so they are not described one by one here.
