Description

Technical Field

[0001] The utility model relates to the technical field of drilling tools, in particular to an energy-saving special reamer for rocks. Background Art

[0002] A rock reamer is a trenchless equipment used for underground pipeline laying. It is mainly used to expand the already drilled guide holes so that it can accommodate larger pipes. This equipment is usually equipped with different types of drill bits to adapt to different geological conditions, including soft rock, medium-hard rock and hard rock formations. Depending on the geological conditions, rock reamer can be divided into barrel reamer, plate reamer, rotary reamer, cone reamer and roller reamer and other types. Each reamer has its own characteristics and scope of application. For example, cone reamer is suitable for various rock formations, especially long-distance crossing reaming operations, while roller reamer is suitable for soft rock and medium-hard rock formations. The working principle of the reamer is to cut and crush the rock through a rotating drill bit, and then use mud or other media to bring the cut rock particles out of the hole, thereby achieving the purpose of reaming.

[0003] At present, when the reamer is used to drill holes in rocks, the angle of the reamer cone is mostly fixed, which is not convenient to adjust according to the use requirements. Different reaming drill bits need to be replaced according to different reaming sizes, which can easily reduce the flexibility and applicability of the reamer. Frequent replacement of reamers can easily slow down work efficiency. To this end, we provide an energy-saving rock-specific reamer to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the utility model provides a technical solution: an energy-saving rock-specific reamer;

[0025] It includes a mounting tube 1, a support ring 9 and a mounting shell 15. Three groups of through grooves 4 are symmetrically opened on the outer side of the mounting tube 1. An electric push rod 10 is arranged on the top of the support ring 9. A telescopic rod 11 is arranged on the output end of the electric push rod 10. The bottom end of the telescopic rod 11 is connected to a connecting ring 12. Three groups of connecting plates 13 are symmetrically arranged on the outer side of the connecting ring 12. The connecting plates 13 movably pass through the interior of the through groove 4. The connecting plates 13 are movably connected to the through groove 4. The support ring 9 is connected and installed on the inner wall of the mounting tube 1, and the support ring 9 is located above the through groove 4. The other end of the connecting plate 13 is connected to a mounting shell 15. Three groups of gears 14 are symmetrically arranged inside the mounting shell 15, and the gears 14 are rotatably connected to the mounting shell 15.

[0026] The support ring 9 is connected and installed on the inner wall of the installation tube 1. The support ring 9 is used to provide installation support for the electric push rod 10, so that the electric push rod 10 is installed inside the installation tube 1. The telescopic rod 11 is the output end of the electric push rod 10, which is connected to the connecting ring 12 through the telescopic rod 11, and then the connecting ring 12 is movably located inside the installation tube 1. After the electric push rod 10 is running, the telescopic rod 11 can drive the connecting ring 12 to move up and down in the installation tube 1. The connecting plate 13 plays a connecting role. One end of the connecting plate 13 is used to rotate at a fixed point and connect with the connecting ring 12, and the other end of the connecting plate 13 is used to be fixedly connected with the installation shell 15. It can be slidably installed in the through groove 4 through the connecting plate 13. When moving downward, the connecting plate 13 slides a certain distance inside the through groove 4, so that the angle of the connecting plate 13 is tilted. The connecting plate 13 acts as a lever. The connecting plate 13 is tilted up and down to adjust the use angle, so that the mounting shell 15 can drive the internally rotating connected cone 14 to tilt the use angle, and there is enough gap between the three groups of mounting shells 15 to adjust the angle, so that it is convenient to adjust the use angle of the cone 14 according to the use requirements, and effectively improve the flexibility and applicability of the reamer when using. The through groove 4 provides the connecting plate 13 with the required activity space for adjusting the angle, and the mounting shell 15 provides the cone 14 with installation space and support. The cone 14 is one of the main components of the reamer, and the rock can be drilled by the cone 14.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the utility model provides a technical solution: an energy-saving rock-specific reamer;

[0028] A crushing head 2 is arranged at the bottom end of the mounting tube 1, and the crushing head 2 is in the shape of a quadrangular pyramid. Three groups of No. 1 spiral plates 3 are symmetrically arranged on the outside of the mounting tube 1, and the No. 1 spiral plates 3 are located below the through groove 4. Three groups of No. 2 spiral plates 5 are symmetrically arranged on the outside of the mounting tube 1, and the No. 2 spiral plates 5 are located above the through groove 4.

[0029] The installation tube 1 is the main component of the energy-saving rock-specific reamer. The interior of the installation tube 1 has a certain space to provide installation space and protection for the internal working components. The rock to be drilled can be positioned and drilled in advance through the crushing head 2. The No. 1 spiral plate 3 and the No. 2 spiral plate 5 are spiral inclined curved plates. When the reamer rotates, the No. 1 spiral plate 3 and the No. 2 spiral plate 5 can be used to spirally push and discharge the crushed rock and soil.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model provides a technical solution: an energy-saving rock-specific reamer;

[0033] Working principle: Before use, the threaded shaft 8 set at the bottom of the connecting shaft 6 is connected to the inner wall of the top end of the installation tube 1, so that the connecting shaft 6 and the installation tube 1 are assembled. The assembly hole 7 opened at the top of the connecting shaft 6 can be used to connect the reamer to external equipment. The rock to be drilled can be positioned, opened and crushed in advance through the crushing head 2 to avoid direct contact between the cone 14 and the rock. By adding the cone 14, the drilling efficiency can be improved to achieve energy-saving effects. The first spiral plate 3 and the second spiral plate 5 are spirally inclined curved plates. When the reamer rotates, the first spiral plate 3 and the second spiral plate 5 can be used to spirally push and discharge the crushed rock and soil. After the push rod 10 is running, the telescopic rod 11 can drive the connecting ring 12 to move up and down in the installation tube 1. One end of the connecting plate 13 is connected to the connecting ring 12 by fixed-point rotation, and the other end is fixedly connected to the installation shell 15. The connecting plate 13 can be slidably installed in the through groove 4. When the connecting ring 12 moves up and down, the connecting plate 13 slides a certain distance in the through groove 4, so that the angle of the connecting plate 13 is tilted, so that the installation shell 15 can drive the internal rotating connected gear 14 to tilt the use angle, thereby facilitating the adjustment of the use angle of the gear 14 according to the use requirements, effectively improving the flexibility and applicability of the reamer when used.
