[0037] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, the specific implementation manners of the present application will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings in the following description are only some embodiments of the present application. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings, and other implementation manners can also be obtained.

[0038] In this article, it should be noted that unless otherwise clearly specified and defined, the terms "install", "connect", and "couple" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0039] In the embodiments shown in the drawings, the indication of directions (such as up, down, left, right, front, and back) is used to explain that the structures and movements of various components of the present application are not absolute but relative. When these components are in the positions shown in the drawings, these explanations are appropriate. If the descriptions of the positions of these components change, the indication of these directions also changes accordingly.

[0040] In addition, in the description of the present application, the terms "first", "second", etc. are only used for distinguishing descriptions, and cannot be understood as indicating or implying relative importance.

[0041] Such as Figure 1As shown, a drill rig generally includes a propulsion beam 9 and a drill bit (not shown). The propulsion beam 9 includes a main beam 1, a drill pipe magazine 2, and a hydraulic oil pipe reel 3. The hydraulic oil pipe reel 3 is connected to the main beam 1. In some embodiments, the hydraulic oil pipe reel 3 can be slidably connected to the main beam 1 so as to be able to move linearly on the guide rail of the propulsion beam through a chain propulsion system. The drill pipe magazine 2 is fixedly connected to the first side of the main beam 1, and this first side is shown in Figure 1 as being located on the left side of the main beam 1. When performing the drill pipe changing operation, the drill pipe in the drill pipe magazine 2 is grasped by a manipulator to complete the drill pipe changing action.

[0042] As Figure 2 shown, in an embodiment of the present application, a noise reduction device for a drill rig according to the present application may include an outer cover 31 of the hydraulic oil pipe reel, an outer cover 21 of the drill pipe magazine, an outer cover 11 of the main beam, and an outer cover 13 of the drill bit. Among them, the outer cover 31 of the hydraulic oil pipe reel is located at one end of the propulsion beam 9, and the outer cover 31 of the hydraulic oil pipe reel can be configured to be connected to the propulsion beam 9 and surround the hydraulic oil pipe reel 3; the outer cover 21 of the drill pipe magazine can be configured to be connected to the propulsion beam 9 and surround the drill pipe magazine 2; the outer cover 11 of the main beam can be located on the second side of the main beam 1 opposite to the first side, and the outer cover 11 of the main beam can be configured to be connected to the propulsion beam 9 and surround the main beam 1; and the outer cover 13 of the drill bit can be located at the other end of the propulsion beam 9, and the outer cover 13 of the drill bit can be configured to be connected to the propulsion beam 9 and surround the drill bit. The noise reduction device for a drill rig according to the present application can form a full enclosure of the propulsion beam 9, thereby implementing the noise reduction device for a drill rig according to the present application.

[0043] In a further embodiment of the present application, the noise reduction device for a drill rig according to the present application may further include a mounting plate 4 and a profile bracket. The mounting plate 4 can be fixedly connected to the main beam 1 through fasteners. The mounting plate 4 can be used both as a baffle for the hydraulic cylinder of the drill rig and as a mounting plate for fixing the profile bracket of the present application.

[0044] The profile bracket may include a first profile bracket 5 extending from the mounting plate 4 parallel to the main beam 1 to the hydraulic oil pipe reel 3 and a second profile bracket 6 extending generally around the hydraulic oil pipe reel 3. The first profile bracket 5 can be fixedly connected to the mounting plate 4 through fasteners or welding, and the second profile bracket 6 can be fixedly connected to the first profile bracket 5 through fasteners or welding. The outer cover 21 of the drill pipe magazine, the outer cover 11 of the main beam, and the outer cover 31 of the hydraulic oil pipe reel can be fixed via the profile bracket and / or the main beam 1. By using this configuration of the mounting plate and the profile bracket, the outer cover 21 of the drill pipe magazine, the outer cover 11 of the main beam, and the outer cover 31 of the hydraulic oil pipe reel can be more firmly installed on the propulsion beam 9.

[0045] In various embodiments, asFigure 4 Best shown in, each of the four faces of the profile bracket according to the present application has a groove, and the cross-section of the profile bracket is generally X-shaped. This type of profile bracket can provide more connection points while increasing strength and stability, facilitating fixation and connection with other components. Additionally, this type of profile does not require further processing during installation, and the groove design also helps improve the load-bearing capacity of the profile and reduce material usage, thereby achieving lightweight and cost-effectiveness. In the present application, fasteners such as bolts can be used to fix the drill pipe magazine outer cover 21, the main beam outer cover 11, and the hydraulic oil pipe reel outer cover 31 through the grooves of the profile bracket of the present application.

[0046] As Figure 6 shown in, in an embodiment of the present application, the hydraulic oil pipe reel outer cover 31 can be, for example, in the shape of a hollow square box, and it can be fixed to the second profile bracket 6 via fasteners such as bolts. The hydraulic oil pipe reel outer cover 31 can be used to surround an end of the propulsion beam 9, specifically, surround the hydraulic oil pipe reel 3, so that the noise transmitted from this end of the drill rig can be reduced.

[0047] As Figure 3 shown in, in an embodiment of the present application, the drill pipe magazine outer cover 21 can include a drill pipe magazine bracket 22, a drill pipe magazine cover plate 23, a first sealing plate 24, and a second sealing plate 25, wherein the first sealing plate 24 is fixedly connected to one of the drill pipe magazine brackets 22 in the drill pipe magazine bracket 22 and the first profile bracket 5 to close the first end of the drill pipe magazine 2 and the area between the first end and the second profile bracket 6. As Figure 3 can be seen, this first end is the end of the drill pipe magazine 2 closest to the hydraulic oil pipe reel.

[0048] The second sealing plate 25 can be fixedly connected to the other drill pipe magazine bracket 22 in the drill pipe magazine bracket 22 to close the second end of the drill pipe magazine 2, and the drill pipe magazine cover plate 23 can be fixed between the drill pipe magazine brackets 22 to surround the drill pipe magazine 2 together with the first sealing plate 24 and the second sealing plate 25. By closing the drill pipe magazine 2, the noise generated by the drill rig can be effectively prevented from being transmitted out of the drill pipe magazine.

[0049] The drill pipe magazine bracket 22 can be made of, for example, stainless steel, which can withstand large pressures and impacts, has good corrosion resistance and wear resistance, and has a relatively long service life. The drill pipe magazine cover plate 23 can be made of, for example, aluminum alloy, thus having good workability and relatively low production costs. It is worth mentioning that since the entire propulsion beam is more than seven meters long and the thickness of the aluminum alloy cover plate is only a few millimeters, if only a single piece of cover plate is used to close the drill pipe magazine, the cover plate may be prone to deformation due to the high-frequency vibration of the drill rig. Therefore, it is preferably to use more than two cover plates to close the drill pipe magazine.

[0050] In a more specific embodiment, four drill pipe magazine brackets 22 and three drill pipe magazine cover plates 23 are adopted. The first sealing plate 24 and the second sealing plate 25 respectively seal the two ends of the drill pipe magazine. And the part of the first sealing plate 24 between the first end of the drill pipe magazine 2 and the second profile bracket 6 can be fixed by an additional connecting member connecting the first sealing plate 24 and the first profile bracket 5. Corresponding threaded holes are provided on the four drill pipe magazine brackets 22 and the three drill pipe magazine cover plates 23, and fasteners such as bolts can be used to fixedly connect the drill pipe magazine cover plates 23 to the drill pipe magazine brackets 22. The drill pipe magazine bracket 22 is integrally U-shaped. One leg of it can be fixedly connected to the first profile bracket 5 by fasteners such as bolts, and the other leg can be fixedly connected to the main beam 1 by fasteners such as bolts.

[0051] In an embodiment of the present application, the part of the first sealing plate 24 between the first end of the drill pipe magazine 2 and the second profile bracket 6 and a surface of the hydraulic oil pipe reel housing 31 on the first side of the propulsion beam can be substantially coplanar. In this way, not only can the material of the drill pipe magazine housing be saved, but also the sealing performance of the drill pipe magazine housing can be better realized, making its sound insulation effect better.

[0052] As Figure 5 shown, in an embodiment of the present application, the main beam housing 11 can be located on the first side of the mounting plate 4 (as Figure 6 shown in Figure 6 ), and as can be seen in

[0053] this, the first side of the mounting plate 4 can be located on the right side of the mounting plate 4. The main beam housing 11 can include a main beam bracket 14 and a main beam upper cover plate 15. The main beam bracket 14 can be made of stainless steel, for example, and the main beam upper cover plate 15 can be made of aluminum alloy, for example. Similarly to the drill pipe magazine cover plate 23, the main beam housing 11 can include a plurality of main beam brackets 14, a plurality of main beam upper cover plates 15 and a plurality of main beam lower cover plates 16. The main beam brackets 14 can be fixedly connected between the first profile bracket 5 and the main beam 1. The main beam upper cover plates 15 can be fixed between the main beam brackets 14. The main beam lower cover plates 16 can be fixedly connected to the main beam 1 via the main beam brackets 14 to limit the main beam upper cover plates 15. Through this structure, the main beam brackets 14, the main beam upper cover plates 15 and the main beam lower cover plates 16 can completely surround the main beam 1.

[0054] In a further embodiment of the present application, the main beam housing 11 can further include a hinge 17 and a hydraulic cylinder 18. The hinge 17 and the hydraulic cylinder 18 connect the first profile bracket 5 and the main beam upper cover plate 15. In a specific embodiment, two hinges 17 and one hydraulic cylinder 18 are provided for each main beam upper cover plate 15, so that the main beam upper cover plate 15 can remain closed under normal circumstances to form a complete enclosure for the main beam 1, and can be opened when maintenance is needed.

[0055] like Figure 2 As shown in , in one embodiment of the present application, the main beam housing 11 may further include a drill head housing 13, which is fixedly mounted on the other end of the propulsion beam 9, the other end being the end opposite to the end where the hydraulic oil hose reel is located. Since the drilling rig will buckle this end to the ground during operation, the drill head housing 13 can be made of a flexible material such as rubber. This material property allows it to tightly adhere to the ground during drilling operation, thereby effectively preventing noise from being transmitted outward.

[0056] In various embodiments, the drill rod storage cover 23, the main beam upper cover 15 and the hydraulic oil pipe reel outer cover 31 can be made of sound-absorbing materials such as aluminum fiber sound-absorbing panels, perforated metal plates, etc., and sound-absorbing layers such as sound-absorbing cotton or sound-absorbing paint can be set on their inner walls, so as to more effectively reduce the spread of noise.

[0057] It is worth mentioning that the profile bracket, hydraulic oil pipe reel cover 31, drill rod magazine cover 21, main beam cover 11 and drill bit cover 13 of the noise reduction device for drilling rigs according to the present application fully surround the propulsion beam of the drilling rig with a compact structure, which does not affect the flexibility of the existing drilling rig at all, and uses lightweight materials as much as possible to achieve maximum shielding of the noise generated by the drilling rig with minimal increase in the total weight of the existing drilling rig.

[0058] The noise reduction device for drilling rigs according to the present application can be applied to top hammer drilling rigs 7. Figure 8 A top hammer drill 7 is a type of drilling equipment widely used in engineering. It utilizes the impact force of a rock drill 32 to break rock and drill a hole. A hydraulic cylinder is used to impact the rock drill 32 and control the up and down movement of the drill rod. The hydraulic cylinder can be mounted on the propulsion beam of the top hammer drill 7 to control the propulsion and retraction of the drill rod. A protective device, such as a baffle, is typically fixed to the end of the hydraulic cylinder to protect it from external damage, such as preventing rocks or other hard objects from hitting the outer wall of the cylinder.

[0059] The propulsion beam of the top hammer drill 7 also includes a main beam, a motor-driven chain propulsion system, a rock drill 32, a drill rod storehouse, and a hydraulic oil hose reel. When the drilling rig is working, the rock drill 32 and the hydraulic oil hose reel move linearly on the guide rail of the propulsion beam through the chain propulsion system. When drilling rocks, the rock drill 32 generates a forward thrust through an external propulsion motor, and the thrust is transferred to the rock through the drill rod. At the same time, the impact piston inside it transfers the impact force to the drill tail, and the drill tail transfers the impact force to the rock through the drill rod, so that the rock drill 32 can be pushed forward while breaking the rock. It can be seen from this that the main source of the noise of the top hammer drill 7 is exactly the high-speed impact of the impact piston of the rock drill 32 on the drill tail, and the greater the impact force, the greater the noise.

[0060] Refer to Figure 9 When applying the noise reduction device for a drilling rig according to the present application, the baffle of the hydraulic cylinder of the top hammer drilling rig 7 can be transformed into a mounting plate 4, and the specific profile of the noise reduction device for a drilling rig according to the present application is fixedly connected to the mounting plate 4. By using the hydraulic oil pipe reel cover 31, the drill pipe library cover 21 and the main beam cover 11 fixed by means of the specific profile and / or the main beam 1 to completely wrap the propulsion beam 9, and then adding the drill bit cover 13, the noise generated by the top hammer drilling rig 7 can be completely isolated.

[0061] In summary, the present application configures the hydraulic oil pipe reel cover, the drill pipe library cover, the main beam cover and the drill bit cover for the propulsion beam of the drilling rig to completely wrap the propulsion beam, and cleverly transforms the existing baffle for the hydraulic cylinder of the drilling rig into the mounting plate of the specific profile bracket of the present application to fixedly install the above covers, so as to achieve the full enclosure of the propulsion beam of the drilling rig with a compact structure without affecting the flexibility of the existing drilling rig; also, sound-absorbing materials and sound-absorbing layers are adopted for the above covers, thereby achieving the complete isolation of the noise source of the drilling rig and the maximum absorption of noise, greatly reducing the propagation of the noise of the drilling rig; and lightweight materials are adopted as much as possible to achieve the maximum shielding of the noise generated by the drilling rig with the least increase in the total weight of the existing drilling rig.

[0062] The present application and its implementation manners are schematically described above. The description is not restrictive, and only one of the implementation manners of the present application is shown in the drawings. The actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the creative purpose of the present application, they shall fall within the protection scope of the present application.
