Description

Technical Field

[0001] This invention belongs to the field of mining technology, specifically relating to a self-propelled rock cutting machine. In addition, this invention also relates to a mechanical cutting mining method. Background Technology

[0002] Existing mining methods are mainly divided into open-cut mining, caving mining, and backfilling mining. Open-cut mining is suitable for ore bodies with relatively stable ore and surrounding rock, where partial exposure of the hanging wall is permissible without causing surface collapse. Caving mining is suitable for ore bodies with large thickness and area, where the surface may collapse after mining. Backfilling mining uses materials to fill the goaf in the stope to prevent collapse of the ore body, hanging wall, and surrounding rock, while also preventing surface collapse.

[0003] However, during the mining process, all the aforementioned methods require strict setting of parameters such as the length, width, and height of the mining area, along with extensive preparatory work. Then, manual or mechanical personnel enter the mining area to perform drilling and blasting. During mining, the movement of personnel and machinery in and out of the mining area and the access shafts, followed by blasting, presents numerous safety hazards, including roof collapses, blasting fumes poisoning, and other risks. Furthermore, the explosive force of the blasting charges damages the surrounding rock and ore body, further reducing the stability of the mining area roof and hanging wall, making such accidents more likely. This is especially true for open-cut mining and backfilling mining methods, which require frequent and large-scale personnel movement in and out of the mining area, resulting in constant safety risks and making it difficult to guarantee the safety of employees.

[0093] Embodiment 1

[0094] In order to solve the problems that the existing rock cutting machine cannot penetrate into the rock, etc., the embodiment of the present application provides a self-propelled rock cutting machine, as shown in the figure, which comprises a machine body 1, a cutting mechanism 2, a walking mechanism 3, and a rotating mechanism 4 are arranged on the machine body 1. Figures 1-4

[0095] In this embodiment, the machine body 1 is moved by the walking mechanism 3, and the cutting mechanism 2 can cut the rock during the movement of the machine body 1, and the machine body 1 can also walk in the slot cut by the cutting mechanism 2, so as to penetrate into the rock and cut, and the rotating mechanism 4 can drive the machine body 1 to rotate as a whole, so as to complete the steering and rotating cutting operation of the machine body 1.

[0096] In this embodiment, the machine body 1 is a rectangular frame structure, that is, the inside of the machine body 1 is a hollow structure for mounting and supporting the cutting mechanism 2, the walking mechanism 3 and the rotating mechanism 4, but the shape of the machine body 1 is not limited to the rectangle of this embodiment, and can be adjusted according to the tunnel environment.

[0097] In this embodiment, as shown in the figure, Figure 1 and 4 ​As shown, the cutting mechanism 2 is disposed on the side of the machine body 1, that is, the extension direction of the cutting mechanism 2 is perpendicular to the moving direction of the machine body 1, so as to... Figure 1 For example, the machine body 1 moves left and right, while the cutting mechanism 2 is set on the top of the machine body 1; the cutting mechanism 2 is rotatably set on the machine body 1 to achieve all-round and all-angle cutting.

[0098] The cutting mechanism 2 includes a mounting cylinder 201, a chainsaw 202, and a chainsaw drive unit 203. The chainsaw 202 is disposed inside the mounting cylinder 201 and extends out of the mounting cylinder 201. The chainsaw drive unit 203 is fixed inside the mounting cylinder 201 and extends out of the mounting cylinder 201.

[0099] Specifically, the mounting cylinder 201 is disposed on the side of the body 1 (i.e., Figure 1 The top of the middle Figure 4 (on the left side of the image), the mounting cylinder 201 is a cylindrical structure with an arc-shaped cover at the end, and the arc-shaped cover of the mounting cylinder 201 extends out of the body 1.

[0100] It should be noted that the end of the mounting cylinder 201 is set to be arc-shaped in this embodiment in order to avoid affecting the rotation of the chainsaw 202 described later. When the chainsaw 202 is fixed as a whole, the end of the mounting cylinder 201 is not limited to an arc-shaped structure.

[0101] Additionally, in order to allow the chainsaw 202 to extend out of the mounting cylinder 201, such as Figure 4 As shown, in this embodiment, a through groove 201-1 is provided on the arc-shaped cover of the mounting cylinder 201. The width of the through groove 201-1 matches the thickness of the chainsaw plate 202-2 (described later), and the length matches the rotation angle of the chainsaw 202 (described later). To install the chainsaw 202 and the chainsaw drive unit 203, as shown... Figure 1 As shown, the mounting cylinder 201 has a rib plate 201-1 arranged along the axial direction inside.

[0102] Specifically, such as Figure 1 and 5 As shown, the chainsaw 202 includes a chainsaw sprocket 202-1, a chainsaw plate 202-2, and a saw chain 202-3 wound around the chainsaw sprocket 202-1 and the chainsaw plate 202-2.

[0103] The specific structure of the chainsaw 202 is as follows: Figure 5 As shown, in this embodiment, the chainsaw blade 202-2 extends out of the mounting cylinder 201 on one side (i.e., Figure 5 A through groove 202-2-1 is provided on the left side of the middle section. The through groove 202-2-1 is rectangular, as shown in the figure. Figure 6As shown, during the process of cutting rocks, the through slot 202-2-1 of the chainsaw 202 can cut off rock blocks. The cut rock blocks are thin-walled and long strips that can break off on their own under their own gravity, or they can break off on their own after being cut in the rotation direction of the chainsaw 202 (described later), thus forming a gap for the machine body 1 to move.

[0104] like Figure 7 As shown, in this embodiment, an alloy plate is provided on the outside of the saw chain 202-3 for cutting rocks, and the links of the saw chain 202-3 are raised to protect the chainsaw plate 202-2 from contact with the rocks.

[0105] like Figure 1 As shown, one end of the chainsaw drive unit 203 is fixed to the rib plate 201-1, and the other end extends out of the mounting cylinder 201. At this time, the drive shaft of the chainsaw drive unit 203 is perpendicular to the chainsaw plate 202-2, and the drive shaft of the chainsaw drive unit 203 passes through the rib plate 201-1 and is connected to the chainsaw sprocket 202-1. When the chainsaw drive unit 203 works, it drives the chainsaw sprocket 202-1 to rotate, which in turn drives the saw chain to rotate for rock cutting.

[0106] To achieve arc-shaped cutting, the cutting mechanism in this embodiment also includes a chainsaw rotation drive unit 204, such as... Figure 1 As shown, the chainsaw rotation drive unit 204 is disposed inside the mounting cylinder 201 and connected to the chainsaw 202 to achieve overall deflection of the chainsaw 202, thereby performing arc-shaped cutting.

[0107] Specifically, such as Figure 1 and 4 As shown, the chainsaw rotation drive unit 204 includes: support plate 204-1, telescopic rod I 204-2, and telescopic rod II 204-3.

[0108] like Figure 1 As shown, the rear side of the support plate 204-1 is movably connected to the drive shaft of the chainsaw drive unit 203 via a bushing, and the front side is fixed to the chainsaw plate 202-2 of the chainsaw 202, that is, the support plate 204-1 can deflect synchronously with the chainsaw 202.

[0109] To ensure stable deflection of the chainsaw 202, such as Figure 4 As shown, in this embodiment, connecting column I and connecting column II are fixedly installed on the support plate 204-1, and both connecting column I and connecting column II are installed on the chainsaw plate 202-2.

[0110] The rib plate 201-1 is provided with an arc-shaped slot I 201-1-1, the arc length of the arc-shaped slot I 201-1-1 matches the deflection angle of the chain saw 202, and the connecting column I and the connecting column II are slidably connected with the arc-shaped slot I 201-1-1.

[0111] As shown in Figure 1 and 4 , the telescopic rod I 204-2 and the telescopic rod II 204-3 are arranged on the upper and lower sides of the support plate 204-1, and the fixed ends of the telescopic rod I 204-2 and the telescopic rod II 204-3 are movably connected with the mounting cylinder 201, the telescopic end of the telescopic rod I 204-2 is movably connected with the connecting column I through a sleeve ring, and the telescopic end of the telescopic rod II 204-3 is movably connected with the connecting column II through a sleeve ring.

[0112] It should be noted that the telescopic rod I 204-2 and the telescopic rod II 204-3 of the embodiment are asynchronous telescopic, as shown in Figure 8 and 9 , that is, when the telescopic rod II 204-3 is extended, the telescopic rod I 204-2 is retracted; when the telescopic rod II 204-3 is retracted, the telescopic rod I 204-2 is extended, so as to realize the axial rotation of the chain saw 202 around the driving shaft of the chain saw driving unit 203.

[0113] In order to realize the overturning of the chain saw 202, as shown in Figure 10 , the cutting mechanism 2 of the embodiment further comprises a mounting cylinder rotation driving unit 205, which is connected with the mounting cylinder 201 and used to drive the mounting cylinder 201 to rotate around its axis, so as to realize the overall overturning of the chain saw 202.

[0114] Specifically, the mounting cylinder 201 is movably connected with the machine body 1, and specific examples of the movable connection are as follows:

[0115] As shown in Figure 10 , four groups of slide ways 101 are arranged in the machine body 1, the four groups of slide ways 101 are annularly and uniformly distributed, and the slide ways 101 have an arc matching the mounting cylinder 201, at this time the mounting cylinder 201 is arranged in the cavity formed by the four groups of slide ways 101.

[0116] In order to further ensure the stable rotation of the mounting cylinder 201, an annular strip can be protruded on the outer wall of the mounting cylinder 201, and a sliding groove can be arranged on the inner wall of each slide way 101, the annular strip can be slidably connected in the sliding groove, which not only ensures the stable rotation of the mounting cylinder 201, but also avoids the axial displacement of the mounting cylinder 201.

[0117] As shown in Figure 10As shown, the mounting cylinder rotating driving unit 205 is a telescopic rod driving structure, specifically, the mounting cylinder rotating driving unit 205 comprises: telescopic rod III 205-1, telescopic rod IV 205-2.

[0118] Specifically, the telescopic rod III 205-1 and the telescopic rod IV 205-2 are arranged opposite to the chain saw driving unit 203, and the fixed ends of the telescopic rod III 205-1 and the telescopic rod IV 205-2 are movably connected with the machine body 1, and the telescopic ends are movably connected with the outer wall of the mounting cylinder 201.

[0119] It should be noted that the telescopic rod III 205-1 and the telescopic rod IV 205-2 of the embodiment are also asynchronous telescopic, like Figure 11 and 12 As shown, when the telescopic rod III 205-1 is extended and the telescopic rod IV 205-2 is retracted, the mounting cylinder 201 rotates clockwise; when the telescopic rod III 205-1 is retracted and the telescopic rod IV 205-2 is extended, the mounting cylinder 201 rotates counterclockwise, thereby realizing the overturning of the chain saw 202.

[0120] In the embodiment, as shown in the figure, Figure 1 The walking mechanism 3 comprises: a walking unit 301 and a walking part driving unit 302.

[0121] Specifically, the walking unit 301 is provided with four groups, and two of the four groups of the walking unit 301 are arranged on the front and rear sides of the machine body 1, like Figure 2 and 3 As shown, each of the walking units 301 comprises walking wheels I 301-1 and walking wheels II 301-2 distributed above and below, i.e. the walking unit 301 of the embodiment is a roller type structure, the walking wheels I 301-1 and the walking wheels II 301-2 are connected with the machine body 1 through respective axles, and the outer circumferential surfaces of the walking wheels I 301-1 and the walking wheels II 301-2 can abut against the slotted groove walls.

[0122] It should be noted that in other embodiments, the walking unit 301 can also be a track type structure, i.e. the walking unit 301 can be composed of two tracks distributed above and below.

[0123] The walking wheels I 301-1 and the walking wheels II 301-2 are driven by a group of the walking part driving units 302, specifically, the walking part driving unit 302 comprises: a walking wheel driving motor 302-1, a driving wheel 302-2, a driven wheel 302-3 and a transmission chain 302-4.

[0124] The walking wheel driving motor 302-1 is arranged inside the machine body 1, and the driving shaft of the walking wheel driving motor 302-1 is arranged in parallel with the wheel shafts of the walking wheel I 301-1 and the walking wheel II 301-2.

[0125] The driving wheel 302-2 is connected to the driving shaft of the walking wheel driving motor 302-1, the driven wheel 302-3 is connected to the wheel shaft of the walking wheel II 301-2, and the transmission chain 302-4 is arranged around the driving wheel 302-2 and the driven wheel 302-3.

[0126] It should be noted that, since the driven wheel 302-3 of the embodiment is provided with a set, the outer circumferential surfaces of the walking wheel I 301-1 and the walking wheel II 301-2 need to abut at this time. When the driving wheel 302-2 is driven to rotate by the walking wheel driving motor 302-1 and the driven wheel 302-3 is driven to rotate under the transmission of the transmission chain 302-4, the walking wheel II 301-2 will rotate synchronously. Since the outer circumferential surfaces of the walking wheel I 301-1 and the walking wheel II 301-2 abut, the walking wheel I will rotate under the driving of the walking wheel II 301-2, and the walking wheel I 301-1 and the walking wheel II 301-2 both abut against the rock surface, so as to realize the same direction movement of the walking wheel I 301-1 and the walking wheel II 301-2, and drive the machine body 1 to move. That is, the walking wheel I 301-1 and the walking wheel II 301-2 of the embodiment form a pair of abutting and same direction movement structure.

[0127] It should be further noted that, in other embodiments, the driven wheel 302-3 can also be provided with two sets, and the two sets of driven wheels are arranged on the wheel shafts of the walking wheel I 301-1 and the walking wheel II 301-2. The transmission chain 302-4 also has two transmission chains. At this time, the walking wheel I 301-1 and the walking wheel II 301-2 are distributed in an upper and lower interval, that is, the synchronous rotation of the walking wheel I 301-1 and the walking wheel II 301-2 can be realized through the two driven wheels 302-3.

[0128] It should be further noted that, the walking wheel I 301-1 and the walking wheel II 301-2 can also be driven to rotate through the corresponding walking part driving units, that is, the walking part driving units 302 correspond to the walking wheels one by one. At this time, the walking part driving unit 302 only includes the walking wheel driving motor.

[0129] In order to make the whole walking unit 301 deflect, as shown in the figure, the walking mechanism 3 of the embodiment further includes a walking part movable driving unit 303, and the walking part movable driving unit 303 corresponds to the walking unit 301 one by one. Figure 2

[0130] ​The walking part movable driving unit 303 is arranged in the machine body 1 and connected with the walking wheel I 301-1 and the walking wheel II 301-2, at this time, the walking wheel I 301-1 and the walking wheel II 301-2 are movably connected with the machine body 1, so as to drive the whole rotation of the walking wheel I 301-1 and the walking wheel II 301-2 by the walking part movable driving unit 303.

[0131] Specifically, the walking part movable driving unit 303 comprises a T-shaped connecting plate 303-1 and a telescopic rod V 303-2.

[0132] The intersection of the T-shaped connecting plate 303-1 is rotatably connected with the machine body 1 through a rotating shaft, and the T-shaped connecting plate 303-1 is provided with three connecting ends, namely a connecting end I, a connecting end II and a connecting end III, the connecting end I and the connecting end II are distributed at 180°, and the connecting end III is distributed at 90° with the connecting end I and the connecting end II; the connecting end I is movably connected with the axle of the walking wheel I 303-1, and the connecting end II is movably connected with the axle of the walking wheel II 301-2.

[0133] The fixed end of the telescopic rod V 303-2 is movably connected with the machine body 1, and the telescopic end is movably connected with the connecting end III.

[0134] In order to ensure the stable rotation of the walking wheel I 301-1 and the walking wheel II 301-2, two arc-shaped grooves II 102 are arranged on the side wall of the machine body 1, and the axles of the walking wheel I 301-1 and the walking wheel II 301-2 are arranged in the corresponding arc-shaped grooves II 102.

[0135] Comparison Figure 2 and 13 It can be known that when the telescopic rod V 303-2 is elongated, the T-shaped connecting plate 303-1 is driven to rotate clockwise, and in turn the axles of the walking wheel I 301-1 and the walking wheel II 301-2 are driven to move along the corresponding arc-shaped grooves II 102, at this time, the whole formed by the walking wheel I 301-1 and the walking wheel II 301-2 rotates clockwise around the axis of the T-shaped chain plate 303-1; that is, the walking wheel I 301-1, the walking wheel II 301-2 and the distance between the slotted groove walls can be adjusted by the walking part movable driving unit 303, not only the pressure of the walking wheel on the groove wall can be adjusted, but also different widths of the slotted groove can be matched, and the machine body can be rotated with the rotary mechanism 4.

[0136] It should be noted that the T-shaped connecting plate 303-1 of the embodiment can also be replaced by two L-shaped connecting plates, at this time, two groups of telescopic rods V 303-2 are needed to drive the rotation of the two L-shaped connecting plates. It should be noted that the T-shaped connecting plate 303-1 of the embodiment can also be replaced by two L-shaped connecting plates, at this time, two groups of telescopic rods V 303-2 are needed to drive the rotation of the two L-shaped connecting plates.

[0137] It should be noted that in other embodiments, the walking part movable driving unit 303 can also be replaced by a bidirectional telescopic rod structure, that is, the walking wheels I 301-1 and the walking wheels II 301-2 are directly connected through a bidirectional telescopic rod.

[0138] In the embodiment, the rotating mechanism 4 is used to drive the whole machine body 1 to rotate, as shown in Figure 2 、 4 The rotating mechanism 4 includes a rotating driving motor 401, a rotating gear 402, a rotating gear ring 403, and a bidirectional telescopic rod I 404.

[0141] When it is necessary to turn the machine body 1, the bidirectional telescopic rod I 404 is elongated to make the two telescopic ends abut against the upper and lower slotted groove walls, respectively, and the walking wheels I 301-1 and the walking wheels II 301-2 are driven by the walking part movable driving unit 303 to rotate towards the inside of the machine body 1, so that the walking wheels I 301-1 and the walking wheels II 301-2 of the walking unit 301 are separated from the slotted groove wall; at this time, when the rotating driving motor 401 drives the rotating gear 402 to rotate, the machine body 1 will rotate in place due to the engagement between the rotating gear 402 and the rotating gear ring 403, thereby driving the machine body 1 to turn.

[0142] The step-by-step working state of the self-propelled rock cutting machine in the embodiment is shown in Figure 14 At the beginning, the machine body 1 advances perpendicularly to the working surface direction, when it moves to a suitable position, the rotating driving motor 401 drives the rotating gear 402 to rotate, thereby driving the whole machine body 1 to rotate, in the process of rotation, the chain saw 202 of the cutting mechanism 2 cuts the rock of the working surface in an arc shape, after one-time rotation cutting is completed, the direction of the machine body 1 is changed.

[0143] Afterwards, the machine body 1 continues to move to the working face direction until it reaches the working face, and then the swing drive motor 401 reversely rotates to drive the machine body 1 to reversely swing for secondary cutting, thereby expanding the cutting range of the front end.

[0144] After the secondary swing cutting is completed, the above steps are repeated to complete the forward cutting operation.

[0145] As shown in Figure 15 , the self-propelled rock cutting machine of the embodiment can also cut the rock in parallel to the working face, at this time, the cutting machine can cut the rock with a fixed thickness and continuously work in parallel to the working face.
