Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary devices for tunnel construction, specifically relating to an assemblable gantry suitable for a drilling, anchoring, and spraying integrated machine. Background Technology

[0002] Drill-and-blast method is one of the most widely used and economical methods in underground cavern construction. It typically includes several processes such as drilling, anchor bolt installation, grouting, arch frame installation and mesh hanging, and shotcreting. In general construction, it often requires multiple equipment changes and multiple batches of personnel. This method is complicated, inefficient, labor-intensive, and produces poor construction quality. Conventional tunnel excavation and support generally use single-function construction equipment, such as rock drilling rigs, anchor bolt rigs, and wet shotcreting rigs, which are rotated and used in rotation. However, the limited space in tunnels prevents these rigs from passing each other, hindering their operation. Most integrated drilling, anchoring, and shotcreting machines on the market use fixed gantry frames, which are only suitable for single cross-sections. When the cross-section changes, new rigs need to be customized, resulting in high manufacturing costs and long lead times. Furthermore, the fixed design makes installation and disassembly inconvenient. During muck removal, the anchor bolt drilling rig can obstruct the passage of the muck removal equipment, requiring it to be moved to a more spacious area to facilitate its operation, thus affecting work efficiency.

[0025] In this embodiment, the column 2 is composed of multiple support columns spliced ​​together. The column 2 is installed at the bottom of the upper frame 11 and forms a "door" shaped structure with the upper frame 11. The column 2 is also set between two adjacent upper frames 11.

[0026] Specifically, since the column 2 and the upper frame 11 form a gate-shaped structure, a middle channel is reserved in the middle, which can not affect the passage of the slag removal equipment after blasting, reduce the interaction time between various work processes, and improve work efficiency.

[0027] The side platform component 3 is installed at the bottom of the column 2;

[0028] Support leg 4 is mounted on the bottom of side platform assembly 3.

[0029] In this embodiment, the support column includes a base plate 21, a support column 22 is installed at the top of the base plate 21, and a top plate 23 is installed at the top of the support column 22. The four corners of the base plate 21 and the top plate 23 are provided with first fixing holes 24. When adjacent support columns are spliced, the base plate 21 at the top and the top plate 23 at the bottom are connected and fixed by bolts installed in the first fixing holes 24. The bottom end of the upper frame 11 is provided with a second fixing hole 13. The support column and the platform assembly are connected and fixed by bolts installed in the first fixing holes 24 and the second fixing holes 13 between the top plate 23 and the upper frame 11.

[0030] Specifically, workers can select different numbers of columns 2 to assemble according to different construction section sizes. When stacking and assembling the columns 2, they are fixed with bolts. Then, the upper frame 11 and the top plate 23 located at the top are connected and fixed with bolts, thus solving the problem that the fixed gantry is only suitable for a single section.

[0031] In this embodiment, the side platform assembly 3 is assembled from multiple side frames 31. The length of the side frame 31 matches the length of the upper frame 11. Mounting holes 32 are provided at both ends of the side frame 31. Two adjacent side frames 31 are connected and fixed by bolts installed in the mounting holes 32. A mounting platform 33 is provided on one side of the side frame 31. A third fixing hole 34 corresponding to the first mounting hole 32 is provided on the surface of the mounting platform 33. The support column and the side platform assembly 3 are connected and fixed by bolts installed in the first fixing hole 24 and the third fixing hole 34 between the base plate 21 and the mounting platform 33. The support leg 4 is installed at the bottom end of the side frame 31 by bolts that fit into the third fixing hole 34.

[0032] Specifically, the side platform assembly 3 is installed between the column 2 and the support leg 4. The third fixing hole 34 on the surface of the mounting platform 33 is aligned with the first fixing hole 24 on the surface of the bottom plate 21 of the column 2 after splicing and is connected and fixed by bolts. Then the support leg 4 is also fixed by bolts in conjunction with the third fixing hole 34, so that the column 2, the side platform assembly 3 and the support leg 4 can be easily installed and disassembled. The work arm is mounted on the side platform assembly 3, which can improve the work efficiency of cross-section construction.

[0033] Example 2

The telescopic platform 5 includes a first fixed rod 51 installed on the side of the support column 22. Several support rods 52 are fixedly installed on the side of the first fixed rod 51. A square tube 53 is sleeved on the outside of the support rod 52. One end of the square tube 53 is fixedly connected to the second fixed rod 54. The telescopic platform 5 also includes a first adjusting rod 55 and a second adjusting rod 56. Several first adjusting holes are opened on the side of the first adjusting rod 55. The support rods 52 are inserted into the first adjusting holes. Several second adjusting holes are opened on the side of the second adjusting rod 56. The square tube 53 is inserted into the second adjusting holes. The size of the first adjusting holes matches the size of the support rods 52, and the size of the second adjusting holes matches the size of the square tube 53.

[0035] Specifically, the expansion area of ​​the telescopic platform 5 is adjustable through the support rod 52 and square tube 53, allowing workers to adjust it according to the size of the construction hole. Furthermore, the number of telescopic platforms 5 can be increased according to different frame sizes and construction requirements, so that the gantry can match different hole wall sizes and carry different work modules. This allows the gantry to load at least 5 working arms on the upper platform assembly 1, side platform assembly 3, and telescopic platform 5 during use, thereby greatly improving work efficiency.

[0036] Working principle: The gantry adopts a split structure design. All components are pre-assembled outside the construction opening. The column 2 adopts a graded combination mode, and different lengths of column 2 can be selected according to the opening size. After selection according to the construction opening size, they are assembled. Each platform adopts a modular design, which facilitates transportation, installation and disassembly. According to different gantry sizes and construction requirements, telescopic platforms 5 can be added, which can not only match different opening wall sizes but also support different work modules, significantly improving the efficiency of large-section construction.
