Description

Technical Field

[0001] This invention relates to the field of drilling equipment, and more specifically, to a drilling equipment suitable for landfills with different terrains. Background Technology

[0002] With the development of the times, people's living standards are constantly improving, and a large amount of waste is generated in people's lives, including some dangerous or harmful waste. This waste needs to be safely treated and disposed of to avoid negative impacts on the environment and human health. The existing waste treatment method is mostly landfill. The efficient collection of landfill gas is of particular practical significance for promoting the resource utilization of landfill gas and improving the operation and management of landfills. However, the existing landfill drilling equipment does not fix the foundation during drilling, which makes the stability of the landfill drilling equipment less than ideal. Therefore, there is an urgent need for a landfill drilling equipment suitable for different terrains.

[0003] For example, Chinese patent CN107542402B discloses a landfill drilling rig, including a working platform, support frame, rotating drive component, drill rod, hydraulic drive mechanism, sampling cylinder, push rod, and drill bit. The rotating drive component and drill rod are mounted on the support frame, and the rotating drive component transmits rotation to the drill bit through the drill rod, reducing the drilling difficulty. However, the aforementioned landfill drilling rig does not reinforce the foundation during drilling, making the drilling device prone to tilting due to the softness of the landfill foundation. This significantly reduces the stability of the drilling device during use, greatly affecting its safety and efficiency.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Summary of the Invention

[0037] In one embodiment, a rotary drilling rig is used to drill holes in moderately weathered rock and slightly weathered andesite. For the overlying soil layer, a hydraulic grab bucket is used to grab the soil and form a trench. Dump trucks transport the excavated soil to determine the drilling location, and semi-permanent axis control points are set on the left and right sides of the drilling location. Single-hole center points are set on the top surface of the trench beams on both the upstream and downstream sides of the trench section, and the hole number and position are marked. Temporary reference piles for the anti-seepage wall axis are set on the upstream side of both sides of the construction trench section to check the quality of each hole. The main method used is "two drillings, one grab, three grabs to form the trench." The excavated soil is temporarily piled behind the trenching machine, awaiting further processing. After the water in the body is dried, it is transported by dump truck to the designated spoil disposal site. Before drilling, the trench is filled with mud. During the drilling process, all trenches must be drilled using the solidified mud method. Depending on the strata, spare clay is added to the trench to reduce slurry leakage and prevent hole collapse. It is strictly forbidden to lift the drill bucket and start drilling before the front outrigger is stable. During drilling, the hole diameter and hole inclination must be measured every shift to prevent dangerous accidents such as trench collapse, hole collapse, or drill jamming. During drilling, the hole inclination can also be controlled within the allowable range by the construction personnel through "frequent measurement and correction". Final hole evaluation: The trench depth must meet the rock embedment depth or design elevation required by the design.

[0038] To facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process will be described in detail below.

[0039] In practical applications, the location where drilling is required is determined, and the stabilizing block 26 is selected according to the terrain of the drilling site. After adjustment, the sliding block 28 is inserted into the sliding groove 24, and then the reinforcing plate 31 is placed into the fixing groove 22 for initial positioning and fixing. After fixing, the placement plate 6 is installed on the top of the bottom platform 20, and the first drilling hole 7, the second drilling hole 21, and the third drilling hole 27 are aligned. Then, the limiting block 44 is placed inside the first support groove 10, and the mounting hole 46, the first limiting hole 12, the second assembly hole 32, and the first assembly hole 23 are connected. The first connecting hole 8 is connected to the bottom platform 20 by connecting bolt 48, and the insert shell 14 is driven into the fixing hole 9. The insert nail 17 is driven into the insert shell 14, so that the extension block 18 is squeezed outward for further installation and fixing. After installation, the mounting top plate 3 is installed on the top of the support rod 43. After installation, the drilling drive device 4 is started to drive the drill bit 5 to drill. After drilling is completed, the fixing nail assembly 13 can be removed by taking out the insert nail 17, digging a hole, pushing the extension plate into the insert shell 14 and taking it out.

[0040] In summary, by means of the above-mentioned technical solution of the present invention, the present invention, by setting up a placement platform 1 and utilizing the cooperation of the support frame 2 and the drilling drive device 4, makes it easy for the drill bit 5 to drill in the landfill. At the same time, by fixing the bottom of the drilling drive device 4 during drilling through the placement platform 1, the stability of the drilling drive device 4 during use is greatly improved. Furthermore, by utilizing the cooperation of the mounting top plate 3 and the placement platform 1, the installation and disassembly efficiency during drilling is greatly improved.

[0041] Furthermore, the present invention facilitates the fixing of the drilling device during use by cooperating with the placement plate 6 and the bottom platform 20. At the same time, the cooperation between the sliding groove 24 and the sliding block 28 allows the drilling device to be replaced with different stabilizing blocks 26 according to the terrain requirements. In addition, the limiting platform 35 can be adjusted according to the characteristics of the terrain. By adjusting and fixing the second limiting plate 42 at different angles, the stability of the drilling device during operation and the applicability range during use are greatly improved.

[0042] Furthermore, by setting up the fixing nail assembly 13, the present invention uses the insertion nail 17 to push the extension block 18 inside the insertion shell 14 outward, thereby improving the stability of the placement platform 1 after installation. At the same time, through the cooperation of the limiting block 44 and the first support groove 10, the support rod 43 can be easily connected and fixed by the fixing bolt 47, and the placement plate 6 and the bottom platform 20 can be connected and fixed by the fixing bolt 47, which greatly improves the stability of the drilling device during use.
