[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportional relationships, or adjustments to the size, without affecting the effects and objectives that the present invention can produce, should fall within the scope of the technical content disclosed in the present invention. It should be noted that in this specification, relational terms such as "first" and "second" are only used to distinguish one entity from several other entities, and do not necessarily require or imply any actual relationship or order between these entities.
[0020] Example 1 Based on the occurrence characteristics and mining technology conditions of steeply dipping thin veins, this embodiment provides a vertical cutting swing support device 2 suitable for steeply dipping thin veins. It is used to perform downward cutting operations in the vertical roadway 3.2 of the mine. It moves downward by gravity or a telescopic mechanism, thereby changing the current situation of lack of mining equipment and technology for steeply dipping thin veins in the mine, realizing efficient, safe and economical mining, improving the ore grade of steeply dipping thin veins, reducing ore dilution and improving the economic benefits of the mine.
[0021] The vertical cutting swing support device 2 includes a cutting mechanism 2.1, a support mechanism 2.2, a swing hinge pin 2.3, a cutting swing cylinder 2.4, a vertical support mechanism, and a vertical support mechanism. The cutting mechanism 2.1 and the support mechanism 2.2 are rotatably connected by the swing hinge pin 2.3. The two ends of the cutting swing cylinder 2.4 are respectively connected to the cutting mechanism 2.1 and the support mechanism 2.2. The vertical support mechanism is used to support the roof 3.2.1 of the vertical roadway in the mine. The vertical support mechanism is used to support the floor 3.2.2 of the vertical roadway in the mine.
[0022] When the angle needs to be adjusted according to the direction of the ore vein, the vertical top support mechanism will contact the top plate 3.2.1 of the vertical roadway of the mine, and the vertical bottom support mechanism will contact the bottom plate 3.2.2 of the vertical roadway of the mine, fixing the support mechanism 2.2 in the horizontal roadway 3.1 of the mine. Then the cutting mechanism 2.1 swings with the swing hinge pin 2.3 as the hinge point through the cutting swing cylinder 2.4.
[0023] In this embodiment, the vertical top support mechanism and the vertical bottom support mechanism are respectively the vertical top support cylinder 2.5 and the vertical bottom support cylinder 2.6 installed on both sides of the support mechanism 2.2; the vertical top support cylinder 2.5 is provided with at least two (e.g., four cylinders) to form surface support and contact with the top plate 3.2.1 of the mine vertical roadway; the vertical bottom support cylinder 2.6 is provided with at least two (e.g., four cylinders) to form surface support and contact with the bottom plate 3.2.2 of the mine vertical roadway.
[0024] In this embodiment, the cutting mechanism 2.1 includes a frame 2.1.1 and a cutting motor 2.1.2, a cutting chain 2.1.3, a left cutting head 2.1.4, and a right cutting head 2.1.5 mounted on the frame 2.1.1. The left cutting head 2.1.4 and the right cutting head 2.1.5 are located on both sides of the cutting chain 2.1.3. The cutting chain 2.1.3 is driven to rotate by the cutting motor 2.1.2, which in turn drives the left cutting head 2.1.4 and the right cutting head 2.1.5 to rotate. The cutting chain 2.1.3 is provided with multiple first left cutting teeth 2.1.6 and multiple first right cutting teeth 2.1.7; the left cutting head 2.1.4 is provided with multiple second left cutting teeth 2.1.8; the right cutting head 2.1.5 is provided with multiple second right cutting teeth 2.1.9; the first left cutting teeth 2.1.6 and the second left cutting teeth 2.1.8 cooperate to form a right helical shape, and the first right cutting teeth 2.1.7 and the second right cutting teeth 2.1.9 cooperate to form a left helical shape.
[0025] The cutting mechanism 2.1 in this embodiment firstly solves the problem that existing all-rock tunneling machines require left and right swinging cutting mechanisms during a single cut to avoid the intermediate reducer housing hitting the front coal and rock. This increases the single cut amount, reduces the left and right swinging cutting time, and greatly improves cutting efficiency. Secondly, the spiral-shaped cutting tooth arrangement makes the cutting force distribution more uniform, making the connection between the cutting chain 2.1.3, the left cutting head 2.1.4, and the right cutting head 2.1.5 smoother during cutting operations. This avoids uneven stress on the entire cutting structure caused by the different cutting frequencies and cutting directions of the left cutting head 2.1.4 and the right cutting head 2.1.5 and the cutting chain 2.1.3 during cutting operations, which would affect the lifespan of the entire cutting mechanism.
[0026] In this embodiment, the chain 2.1.3 is provided with a plurality of intermediate cutting teeth 2.1.10; the plurality of intermediate cutting teeth 2.1.10 are arranged along the central axis of the chain 2.1.3; each intermediate cutting tooth 2.1.10 has a plurality of first left cutting teeth 2.1.6 arranged on its left side and a plurality of first right cutting teeth 2.1.7 arranged on its right side, the first left cutting teeth 2.1.6 and the first right cutting teeth 2.1.7 are arranged symmetrically, and each intermediate cutting tooth 2.1.10 and the first left cutting teeth 2.1.6 and the first right cutting teeth 2.1.7 on both sides constitute a [missing information]. V-shaped structure; multiple V-shaped structures are evenly arranged on the cutting chain 2.1.3; during the rotation of the cutting chain 2.1.3 and the left cutting head 2.1.4, the first left cutting tooth 2.1.6 and the middle cutting tooth 2.1.10 in the multiple V-shaped structures cooperate with the second left cutting tooth 2.1.8 in turn to form a right-hand spiral shape; during the rotation of the cutting chain 2.1.3 and the right cutting head 2.1.5, the first right cutting tooth 2.1.7 and the middle cutting tooth 2.1.10 in the multiple V-shaped structures cooperate with the second right cutting tooth 2.1.9 in turn to form a left-hand spiral shape.
[0027] The above design ensures more continuous and uniform contact between the cutting teeth and the coal and rock during the rotation of the cutting head, improving the continuity and efficiency of the cutting. The V-shaped structure enhances the cutting force of the cutting teeth, improving the cutting effect.
[0028] The vertical cutting swing support device 2 also includes a slipper guide mechanism 2.7 (in the form of a guide guard plate) connected to the cutting mechanism 2.1 and an electrical control box for controlling the cutting mechanism 2.1.
[0029] The cutting swing cylinder 2.4, the vertical support cylinder 2.5 (number ≥ 2, such as 4 cylinders forming surface support) and the vertical bottom support cylinder 2.6 (number ≥ 2, such as 4 cylinders forming surface support) in the vertical cutting swing support device 2 are all powered by the oil tank pump station 1.8 and controlled by the operating panel 1.9. The cutting mechanism 2.1 is mainly driven by the cutting motor 2.1.2, which drives the reducer to transmit torque through the cutting chain 2.1.3, so that the horizontal axis cutting head can also rotate synchronously to perform cutting operations.
[0030] Example 2 This embodiment provides a vertical mining device suitable for steeply inclined thin veins, including a mobile winch device 1 and a vertical cutting swing support device 2 as described in Embodiment 1.
[0031] The mobile winch device 1 includes a frame 1.1, a traveling mechanism 1.2, and a traction mechanism; the traveling mechanism 1.2 is installed below the frame 1.1; the traction mechanism includes a drum 1.3.1, a wire rope 1.3.2, and a drum drive assembly; the drum 1.3.1 is rotatably mounted on the frame 1.1 and is driven to rotate by the drum drive assembly; the wire rope 1.3.2 is wound on the drum 1.3.1, and the extended end is connected to the support mechanism 2.2.
[0032] The mobile winch device 1 moves in the horizontal mine roadway 3.1 through the walking mechanism 1.2. Since the mine roadway surface is rugged and has poor pressure bearing capacity, this embodiment adopts a tracked walking mechanism, which has good passability and off-road capability, and has a large ground contact area, which can distribute the weight of the device, reduce the pressure on the road surface, and thus protect the road surface from damage.
[0033] Because the vertical cutting swing support device 2 generates significant vibration during cutting operations in the vertical mine roadway 3.2, this embodiment employs a gear transmission for rotating the drum 1.3.1, which offers higher operational stability. The drum drive assembly includes a motor 1.3.3, a reducer 1.3.4, a drive gear 1.3.5, and a driven gear 1.3.6. The motor 1.3.3 is mounted on the frame 1.1, with its output end connected to the input end of the reducer 1.3.4. The output end of the reducer 1.3.4 is connected to the drive gear 1.3.5. The driven gear 1.3.6 is fixedly mounted on the first end of the drum 1.3.1 and meshes with the drive gear 1.3.5. The diameter of the driven gear 1.3.6 is larger than the diameter of the drive gear 1.3.5.
[0034] The mobile winch device 1 also includes a horizontal roof support mechanism and a horizontal floor support mechanism; the horizontal roof support mechanism is used to support the roof 3.1.1 of the mine horizontal roadway; the horizontal floor support mechanism is used to support the floor 3.1.2 of the mine horizontal roadway.
[0035] When the vertical cutting swing support device 2 is in the downward cutting operation state or the upward traction and retraction state, the mobile winch device 1 is in a stationary state. The horizontal support mechanism is in contact with the roof 3.1.1 of the mine horizontal roadway, and the horizontal support mechanism is in contact with the floor 3.1.2 of the mine horizontal roadway, which ensures the stability of the mobile winch device 1 in the mine horizontal roadway 3.1, and at the same time ensures the stability of the vertical cutting swing support device 2 during the hoisting process.
[0036] In this embodiment, the horizontal top support mechanism includes a horizontal top support cylinder 1.4 mounted on the frame 1.1, and the horizontal bottom support mechanism includes a horizontal bottom support cylinder 1.5 mounted on the frame 1.1. The horizontal top support cylinder 1.4 is provided with at least two (e.g., four cylinders) to form a surface support and contact the top plate 3.1.1 of the mine horizontal roadway. The horizontal bottom support cylinder 1.5 is provided with at least two (e.g., four cylinders) to form a surface support and contact the bottom plate 3.1.2 of the mine horizontal roadway.
[0037] The mobile winch device 1 also includes a braking mechanism 1.6 for braking the drum 1.3.1. In this embodiment, the braking mechanism 1.6 includes a brake pad and a hydraulic clamp; the brake pad is fixedly installed at the second end of the drum 1.3.1 and rotates with the drum 1.3.1. The hydraulic clamp achieves braking by clamping the brake pad. The whole structure is simple and the braking is reliable.
[0038] The mobile winch device 1 also includes a guide mechanism 1.7 rotatably mounted on the frame 1.1; the wire rope 1.3.2 is led out from the drum 1.3.1, passes through the guide mechanism 1.7, and connects to the vertical cutting swing support device 2. The guide mechanism 1.7 improves the stability of the drum 1.3.1 during winding and unwinding, and prevents the wire rope 1.3.2 from becoming tangled. The cable of the cutting mechanism 2.1 passes through the guide mechanism 1.7 and connects to the electrical control box located on the frame 1.1, and is wound and unwound synchronously with the wire rope 1.3.2 to ensure the normal operation of the cutting mechanism 2.1.
[0039] The mobile winch device 1 also includes an oil tank pump station 1.8 and an operating platform 1.9 mounted on the frame 1.1.
[0040] The hydraulic pipes of the cutting swing cylinder 2.4, the vertical support cylinder 2.5, and the vertical support cylinder 2.6 bypass the guide mechanism 1.7 and connect to the oil tank pump station 1.8 located on the frame 1.1, and are wound and released synchronously with the wire rope 1.3.2.
[0041] The mobile winch device 1 is controlled via the control panel 1.9 and uses the oil tank pump station 1.8 as its power source to drive the tracked walking mechanism. The horizontal top support cylinders 1.4 (≥2, e.g., 4 cylinders forming surface support) and the horizontal bottom support cylinders 1.5 (≥2, e.g., 4 cylinders forming surface support) also use the oil tank pump station 1.8 as their power source and are controlled via the control panel 1.9 to extend or retract. The motor 1.3.3 drives the reducer 1.3.4 to rotate the drum 1.3.1. The extension or retraction of the wire rope 1.3.2 is achieved through the guide mechanism 1.7 (which allows for independent guidance of the wire rope 1.3.2, cable, hydraulic pipe, etc.), and the braking mechanism 1.6 ensures that the drum 1.3.1 stops rotating.
[0042] Example 3 This embodiment provides a vertical mining method suitable for steeply inclined thin veins. It is a mechanized vertical mining method that mainly uses pillar mining and employs vertical or steeply inclined shafts (vertical shafts or inclined shafts) to directly penetrate the ore body. It is mined in sections from top to bottom, with simultaneous mining and backfilling. Specifically, it includes the following steps: S1, a directional drilling rig is used to drill a pilot hole from top to bottom in the upper part of the ore body to solve the problem of the pilot hole's penetration accuracy; S2, replace the reverse drilling bit in the lower part of the ore body, and carry out borehole enlargement construction from bottom to top to form the mine vertical roadway 3.2; S3. Mining is carried out using the aforementioned vertical mining device suitable for steeply inclined thin veins. The mobile winch device 1 is placed in the horizontal mine roadway 3.1 above the ore body, and the vertical cutting swing support device 2 is placed in the vertical mine roadway 3.2 of the first mining area. The horizontal support cylinder 1.4 extends out and contacts the roof 3.1.1 of the horizontal mine roadway, and the horizontal support cylinder 1.5 extends out and contacts the bottom 3.1.2 of the horizontal mine roadway. The mobile winch device 1 is fixed, and the drum 1.3.1 is driven to rotate in the forward direction, causing the vertical cutting swing support device 2 to move downward. When it moves to the first cutting position, the vertical support cylinder 2.5 extends out and contacts the bottom 3.1.2 of the horizontal mine roadway. The vertical roadway roof 3.2.1 contacts the vertical support cylinder 2.6, which extends to contact the vertical roadway floor 3.2.2, fixing the support mechanism 2.2 inside the horizontal roadway 3.1. The cutting mechanism 2.1 performs the first cut. After the first cut, the vertical support cylinder 2.5 and the vertical support cylinder 2.6 retract, driving the drum 1.3.1 to continue rotating in the forward direction, causing the vertical cutting swing support device 2 to continue moving downward to the second cut position. The vertical support cylinder 2.5 and the vertical support cylinder 2.6 extend to fix the support mechanism 2.2, and the cutting mechanism 2.1 performs the second cut until the first mining area is completed. When the angle needs to be adjusted according to the direction of the ore vein, the vertical top support cylinder 2.5 and the vertical bottom support cylinder 2.6 extend to fix the support mechanism 2.2, and the cutting mechanism 2.1 swings through the cutting swing cylinder 2.4 with the swing hinge pin 2.3 as the hinge point to adjust it to adapt to the direction of the ore vein. In the working face roadway 4, a scraper transfer machine 5 and a retractable belt conveyor 6 are used to transport the falling ore. In the transport roadway, mine cars are used to transport the ore. S4, after the first mining area is completed, the vertical top support cylinder 2.5 and the vertical bottom support cylinder 2.6 retract, driving the drum 1.3.1 to rotate in the opposite direction, pulling the vertical cutting swing support device 2 onto the mobile winch device 1, the horizontal top support cylinder 1.4 and the horizontal bottom support cylinder 1.5 retract, the mobile winch device 1 moves to the second mining area, the vertical cutting swing support device 2 mines the second mining area, and at the same time fills the first mining area; S5. Repeat step S4 until all mining areas are mined and backfilled.
