[0002] When performing tasks such as corner trimming, drainage ditch excavation, or construction of isolation or sealing walls in underground coal mine roadways, trenching operations are required in the roadway rock mass or floor slab. Furthermore, in areas with relatively soft floors, especially in coal roadways, semi-coal-rock roadways, or areas with significant mine pressure, phenomena such as roadway floor bulging, sidewall detachment, and roof subsidence and deformation are more prominent, necessitating timely roadway floor leveling, sidewall scraping, roof lifting, or trenching operations. Conventional trenching operations generally rely primarily on manual labor or non-specialized equipment, such as manually operating pneumatic picks and rock drills. This involves a large workload, low efficiency, and also poses certain safety hazards.

[0003] Therefore, a more flexible mechanized grooving equipment is needed to expand the operating range and improve the grooving effect and operating efficiency. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Example 1:

[0039] like Figure 1 and Figure 2 As shown, this utility model provides a mining rubber-wheeled hydraulic grooving machine, which adopts rubber-wheeled walking and includes a front frame and a rear frame. The working tool 1 is installed on the fixed platform at the front of the front frame through the working arm composed of a rotary swing seat 12, a rocker arm 5 and a telescopic arm assembly 3, so that the working tool 1 has a large working range and working angle.

[0040] Combined Figure 3 As shown, the lower end of the rocker arm 5 is hinged to the rotary swing seat 12, and a rocker arm cylinder 11 is hinged between the middle of the rocker arm 5 and the rotary swing seat 12. The forward and backward tilting movements of the rocker arm 5 are controlled by the extension and retraction of the rocker arm cylinder 11.

[0041] The telescopic boom assembly 3 includes a telescopic inner boom 302 and a telescopic outer boom 301. The telescopic outer boom 301 is slidably fitted onto the outside of the telescopic inner boom 302 along its length. Symmetrical telescopic cylinders 4 are arranged on both sides of the telescopic outer boom 301. The two ends of the telescopic cylinders 4 are hinged to the front end of the telescopic outer boom 301 and the rear end of the telescopic inner boom 302, respectively. The telescopic extension and retraction of the telescopic outer boom 301 along the telescopic inner boom 302 is controlled by the extension and retraction of the telescopic cylinders 4.

[0042] The rear end of the telescopic inner boom 302 is hinged to the upper end of the rocker arm 5. The bottom end of the luffing cylinder 6 is hinged to the lower part of the rocker arm 5, and the piston rod end of the luffing cylinder 6 is hinged to the luffing cylinder support 601 and the luffing cylinder connecting rod 602. The other end of the luffing cylinder support 601 is hinged to the rear end of the telescopic inner boom 302, and the other end of the luffing cylinder connecting rod 602 is hinged to the upper part of the rocker arm 5. The luffing action of the telescopic boom assembly 3 is controlled by the extension and retraction of the luffing cylinder 6.

[0043] The base of the working implement 1 is hinged to the front end of the telescopic boom 301. The bottom end of the working cylinder 2 is hinged to the rear of the telescopic boom 301, and the piston rod end of the working cylinder 2 is hinged to the working implement frame 101 and the working implement connecting rod 102. The other end of the working implement frame 101 is hinged to the base of the working implement 1, and the other end of the working implement connecting rod 102 is hinged to the upper part of the telescopic boom 301. The rotation angle of the working implement 1 relative to the telescopic boom 301 is controlled by the extension and retraction of the working cylinder 2. In this embodiment, the working implement 1 is a milling machine, but for different operational needs, the working implement 1 can be fitted with different functional components through the base, such as a bucket, a breaker hammer, and hydraulic shears, so that the grooving machine can perform different tasks such as digging, crushing, milling, and shearing.

[0044] Combined Figure 4 As shown, the rotary swing seat 12 is bolted to the base rotary reducer 121, which is fixedly mounted on a fixed platform at the front of the front frame. The rotary reducer 121 controls the rotation of the rotary swing seat 12. In this embodiment, the rotary swing seat 12 can rotate 210° (±105° left and right) around the rotation center. Combined with the rocker arm 5 and the telescopic arm assembly 3, the working tool 1 can be placed at any position within the working range, leaving no dead angles, making it flexible and convenient, and greatly improving work efficiency.

[0045] In this embodiment, both the luffing cylinder 6 and the rocker arm cylinder 11 are two-stage cylinders. Two-stage cylinders have advantages such as compact structure, small size, long stroke, and large thrust, making the entire boom mechanism more flexible and with a larger range of motion. This allows for flexible operation within different height sections, avoiding contact with anchor bolts, anchor cables, and the roadway roof, thus enhancing safety during operation. The two telescopic cylinders 4 installed on the telescopic boom assembly 3 form a single-stage telescopic boom with a large telescopic stroke, suitable for operation in the narrow spaces of coal mine roadways. Selecting appropriate control methods based on different working conditions greatly improves the adaptability of the slotting machine.

[0046] Example 2:

[0047] Based on the above embodiment one, combined with Figure 1 , Figure 2 and Figure 4As shown, this utility model adopts an articulated frame structure, including a front frame 15 and a rear frame 17.

[0048] The front frame 15 and rear frame 17 form the base for connecting and installing all components of the entire equipment. The cab 7 is installed at the rear of the front frame 15. The front frame 15 and rear frame 17 are connected by an upper hinge shaft 8 and a lower hinge shaft 16 that are vertically opposite each other. The upper hinge shaft 8 and lower hinge shaft 16 are coaxial, allowing the front frame 15 and rear frame 17 to rotate around them. A steering cylinder 9 is hinged between the front frame 15 and rear frame 17. The extension and retraction of the steering cylinder 9 controls the swing angle between the front frame 15 and rear frame 17. In this embodiment, when the steering cylinder 9 is activated, it can achieve a relative swing of ≥±40° between the front frame 15 and rear frame 17, thereby achieving vehicle steering. A front axle 14 is mounted under the front frame 15, and a rear axle 18 is mounted under the rear frame 17 via a swing frame 181. Rubber wheels are mounted on both sides of the front axle 14 and the rear axle 18 to enable the vehicle to move.

[0049] The front frame 15 has front transverse support legs 13 fixed on both sides of the front fixed platform, and the rear frame 17 has rear longitudinal support legs 19 fixed at the rear. When the grooving machine is operating, the front transverse support legs 13 and the rear longitudinal support legs 19 can be used to support the tunnel floor, further improving the stability of the vehicle during construction.

[0050] Example 3:

[0051] Based on the above-described embodiment two, combined with Figure 1 and Figure 4 As shown, this utility model provides a power assembly 10, which mainly includes an explosion-proof diesel engine system, a hydraulic pump assembly, and an electrical system.

[0052] A water tank 171 is installed above the rear frame 17, a hydraulic oil tank 172 is installed in the middle of the right side of the rear frame 17, and a transfer case 20 is installed at the bottom of the rear frame 17. The transfer case 20 is powered by a fixed displacement pump 201, which is connected to the transfer case 20 via a pump station connector 202. In this embodiment, both the front axle 14 and the rear axle 18 are drive axles, and the rear axle 18 is connected to the transfer case 20 via a rear drive shaft 206. A drive shaft mounting seat 203 is fixedly installed on the lower connecting plate of the front frame 15, and the two ends of the drive shaft mounting seat 203 are respectively connected to a front drive shaft 204 and a middle drive shaft 205; the front axle 14 is connected to the transfer case 20 in sequence via the front drive shaft 204, the drive shaft mounting seat 203, and the middle drive shaft 205.

[0053] The grooving machine in this embodiment adopts a hydrostatic-mechanical transmission system. It relies on the engine output power in the explosion-proof diesel engine system, and then converts the kinetic energy into hydraulic energy through the hydraulic pump assembly. Then, the hydraulic energy of the liquid is converted into mechanical energy through the hydraulic motor and transmitted to the transfer case 20. The transfer case 20 then transmits the power to the rear axle 18 through the rear drive shaft 206, and to the front axle 14 through the middle drive shaft 205 and the front drive shaft 204. The front and rear axle wheel-side reducers on both sides of the front and rear axles drive the rubber wheels to realize the forward and backward movement of the grooving machine.

[0054] As can be seen from the above embodiments, the mining rubber-wheeled hydraulic grooving machine provided by this utility model adopts a rubber-wheeled walking system and a front and rear articulated frame structure, which has the advantages of flexible steering and fast walking speed. It can adapt to complex underground road conditions and is convenient for relocation. The front working arm adopts a three-section arm design, which has the advantages of compact structure and small space occupation. The front-mounted slewing swing seat can rotate ±105° along the vehicle axis. Combined with the extension and luffing movements of the working arm, the working range of the grooving machine can be greatly extended, leaving no dead corners during construction, which is flexible and convenient, reduces the frequency of equipment movement, and improves work efficiency. The working tool at the end of the working arm adopts a milling machine for grooving, and can also be replaced with other different functional components, such as buckets, breakers, hydraulic shears, etc., to realize different tasks such as excavation, crushing, milling, and shearing, and complete a variety of roadway repair operations, making it more adaptable.

[0055] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
