Description

Technical Field

[0001] This invention relates to the field of coal mine roadway excavation technology, and in particular to a tunneling and anchoring transfer device for coal roadways or semi-coal-rock roadways. Background Technology

[0002] Rapid excavation of coal mine roadways (including coal roadways and semi-coal-rock roadways) is a crucial link in ensuring efficient and safe coal mine production. However, traditional roadway excavation operations typically involve multiple processes such as cutting, loading, transportation, and bolt support. These processes are often completed step-by-step by independent equipment (such as tunneling machines, transfer machines, and bolt drilling rigs). This operational mode not only results in a large number of equipment and their dispersed layout, but also requires the tunneling machine to exit the working face after completing a cutting cycle, allowing the bolt drilling rig to enter for support work. This frequent equipment switching severely restricts excavation efficiency, making it difficult to achieve parallel and continuous operation of excavation and bolt support, thus becoming a major bottleneck restricting the speed of roadway excavation.

[0003] Meanwhile, existing tunneling equipment lacks effective attitude adjustment capabilities for the tunneling-anchoring-transporting components during the cutting process. When fine adjustments to the tunneling direction are needed, multiple vehicle repositioning is required, which affects cutting efficiency. Anchoring efficiency is also insufficient. Furthermore, the self-moving tail assembly behind the tunneling-anchoring-transporting components has a relatively simple function, usually only having a transportation function.

[0004] Therefore, there is an urgent need to develop a tunneling and anchoring transfer device for coal roadways or semi-coal-rock roadways to overcome the above-mentioned defects. Summary of the Invention

[0005] The purpose of this invention is to disclose a tunneling and anchoring transfer device for coal roadways or semi-coal-rock roadways.

[0006] To achieve the first objective mentioned above, the present invention provides a tunneling and anchoring transfer device for coal roadways or semi-coal-rock roadways, comprising a tunneling and anchoring transfer assembly and a self-moving tail assembly; The excavation, anchoring, and transport assembly includes a first chassis, a first anchoring assembly, a cutting assembly, a first transport assembly, and a posture adjustment assembly. The posture adjustment assembly is located at the rear of the first chassis. The first transport assembly includes a loading section, a front transport section, a rear transport section, and a tail swing assembly. The self-moving tail assembly is provided with a second chassis, a crushing assembly, a second anchoring assembly, and a second transport assembly. The crushing assembly receives coal from the tail assembly, and the second anchoring assembly is located on the rear side of the crushing assembly. The coal cut by the cutting component is transferred successively by the first transport component and the second transport component.

[0007] Preferably, the first anchoring assembly includes a front anchoring assembly, a middle anchoring assembly, and a tail anchoring assembly respectively disposed at the front end, middle part, and rear end of the first chassis.

[0008] Preferably, the cutting assembly includes a cutting head, a cutting boom, a sliding frame, guide columns, and front and rear telescopic cylinders, with the cutting boom mounted on the sliding frame.

[0009] Preferably, the front transport section and the rear transport section are hinged together by a horizontal column, and the rear transport section and the tail swing assembly are hinged together by a vertical column. The tail end of the sliding frame is provided with a sliding groove, and the front and rear telescopic cylinders drive the sliding frame to move back and forth. The sliding frame drives the first transport component to move back and forth along the slide rail through the sliding groove and the horizontal column.

[0010] Preferably, the attitude adjustment assembly includes a horizontal support plate, a first horizontal slide rail, a first slide block, a second horizontal slide rail, a second slide block, a first lifting cylinder, a second lifting cylinder, and an attitude adjustment cylinder.

[0011] Preferably, the first lifting cylinder is installed inside the first bracket; The first lifting cylinder drives the first slide block to rise and fall, and the first slide block moves left and right along the first horizontal slide rail; The second lifting cylinder drives the second slide block to rise and fall, and the second slide block moves left and right along the second horizontal slide rail; The posture adjustment cylinder drives the first bracket to move left and right with the horizontal support plate as the fulcrum.

[0012] Preferably, the front anchoring assembly includes four drill arms, the middle anchoring assembly includes two drill arms, and the tail anchoring assembly includes two drill arms.

[0013] Preferably, the second anchoring assembly includes a lateral movement component and a drill arm, wherein the lateral movement component drives the drill arm to move left and right.

[0014] Preferably, the self-moving tail assembly is further provided with a dust removal component, a water tank, and a pump station.

[0015] Preferably, both the first chassis and the second chassis are driven by tracks.

[0016] Compared with the prior art, the beneficial effects of the present invention are: (1) By setting an attitude adjustment component at the tail of the first chassis of the tunneling and anchoring assembly, the present invention enables the cutting assembly to swing left and right. When the tunneling direction needs to be finely adjusted, it is not necessary to move the heavy vehicle frequently like traditional equipment. The cutting direction can be accurately adjusted by driving the first chassis to swing slightly left and right through the attitude adjustment cylinder. This significantly reduces the number of times and time to move the vehicle, and improves the continuity and efficiency of the cutting operation.

[0017] (2) By setting the front anchoring component, middle anchoring component and tail anchoring component at the front, middle and rear of the first chassis respectively, the top, side and bottom of the roadway can be anchored simultaneously in all directions and at multiple angles. In addition, the second anchoring component of the self-moving tail component completely changes the traditional equipment mode of multiple alternations and step-by-step support, greatly reduces the open roof area, and effectively ensures the safety of the roadway roof and the safety of the workers while improving the anchoring efficiency.

However, it should be noted that these embodiments are not intended to limit the present invention.

Therefore, they should not be construed as limiting this invention.

[0032] The specific implementation process of the present invention will be described below through several embodiments. Example 1

[0033] See Figures 1 to 10 This embodiment discloses a specific implementation of a tunneling and anchoring transfer device for coal roadways or semi-coal-rock roadways.

[0034] For use in coal roadways or semi-coal-rock roadways, see the anchor transfer device. Figures 1 to 10 The system includes a tunneling and anchoring transport assembly 1 and a self-propelled tail assembly 2. The self-propelled tail assembly 2 follows and transports the coal mined by the tunneling and anchoring transport assembly 1. The tunneling and anchoring transport assembly 1 is provided with a first chassis 11, a first anchoring assembly 12, a cutting assembly 13, a first transport assembly 14, and a posture adjustment assembly 15. The posture adjustment assembly 15 is located at the tail of the first chassis 11. The first transport assembly 14 includes a loading section 141, a front transport section 142, a rear transport section 143, and a tail swing assembly 144. The self-propelled tail assembly 2 is provided with a second chassis 21, a crushing assembly 22, a second anchoring assembly 23, and a second transport assembly 24. The crushing assembly 22 receives the coal from the tail swing assembly 144 and crushes it. The second anchoring assembly 23 is located behind the crushing assembly 22. The coal cut by the cutting assembly 13 is transported successively by the first transport assembly 14 and the second transport assembly 24.

[0035] Specifically, see Figures 1 to 10 In this embodiment, the cutting assembly 13 performs cutting operations by moving back and forth and pitching. The cut coal is transported to the self-moving tail assembly 2 after passing through the loading section 141, the front transport section 142, the rear transport section 143, and the tail swing assembly 144. During the tunneling process, the first anchoring assembly 12 and the second anchoring assembly 23 provide support, realizing the systematic coordination of tunneling, anchoring, and transport. At the same time, this embodiment provides the cutting assembly 13 with the ability to swing left and right by setting the attitude adjustment assembly 15 at the tail of the first chassis 11 of the tunneling, anchoring, and transport assembly. When the tunneling direction needs to be finely adjusted, it is not necessary to move the heavy vehicle frequently like traditional equipment. The first chassis 11 can be driven to swing slightly left and right by the attitude adjustment cylinder, which can achieve precise adjustment of the cutting direction. This significantly reduces the number of times and time to move the vehicle, and improves the continuity and efficiency of the cutting operation.

[0036] See Figures 1 to 10The working principle of the attitude adjustment component 15 is as follows: The attitude adjustment component 15 includes a horizontal support plate 151, a first horizontal slide rail 152, a first slide block 153, a second horizontal slide rail 154, a second slide block 155, a first lifting cylinder 156, a second lifting cylinder 157, and an attitude adjustment cylinder 158; wherein, the first lifting cylinder 156 is installed in the first bracket 1561, and the first lifting cylinder 156 drives the first slide block 153 to rise and fall, and the first slide block 153 moves left and right along the first horizontal slide rail 152; the second lifting cylinder 157 is installed in the second bracket 1571, and the second lifting cylinder 157 drives the second slide block 155 to rise and fall, and the second slide block 155 moves left and right along the second horizontal slide rail 154; the attitude adjustment cylinder 158 drives the first bracket 1561 to move left and right with the horizontal support plate 151 as the fulcrum; the first bracket 1561 and the second bracket 1571 are a connected structure, and the fulcrum of the attitude adjustment cylinder 158 is close to the horizontal support plate 151. The first support 1561 is driven by the second slide block 155; when the tunnel excavation direction needs to be finely adjusted, the first anchoring assembly 12, the cutting assembly 13, and the first transport assembly 14 all stop operating, and the first lifting cylinder 156 and the second lifting cylinder 157 extend synchronously. Driven by the first slide block 153 and the second slide block 155, the horizontal support plate 151 first contacts the ground, and the first lifting cylinder 156 and the second lifting cylinder 157 continue to extend, driving the tail of the first chassis 11 to lift up and detach from the ground. The front end of chassis 11 contacts the ground, causing the first chassis 11 to tilt. Finally, the attitude adjustment cylinder 158 is activated, driving the first slide block 153 to move along the first horizontal slide rail 152 and the second slide block 155 to move along the second horizontal slide rail 154. Depending on the degree of deviation in the tunneling direction, the attitude adjustment cylinder 158 drives the first support 1561 and the second support 1571 to make slight adjustments to the left or right, thereby driving the first chassis 11 to make slight adjustments to the left or right. This achieves slight adjustment of the tunneling direction without moving the vehicle, improving tunneling efficiency.

[0037] See Figures 1 to 10By using the front anchoring assembly 121, middle anchoring assembly 122, and tail anchoring assembly 123 respectively located at the front, middle, and rear of the first chassis 11, simultaneous anchoring operations can be performed on the top, side walls, and bottom of the roadway from all directions and at multiple angles. Combined with the second anchoring assembly 23 of the self-moving tail assembly 2, this technical solution completely changes the traditional equipment's need for multiple alternating and step-by-step support, significantly reducing the unsupported roof area. While improving anchoring efficiency, it effectively ensures the safety of the roadway roof and the safety of workers. Specifically, the first anchoring assembly 12 includes the front anchoring assembly 121, middle anchoring assembly 122, and tail anchoring assembly 123 respectively located at the front, middle, and rear of the first chassis 11. The front anchoring assembly 121 includes four drill arms 3, primarily anchoring the top of the roadway; the middle anchoring assembly 122 includes two drill arms 3, primarily anchoring the two side walls of the roadway; and the tail anchoring assembly 123 includes two drill arms 3, primarily anchoring the bottom of the two side walls of the roadway. The second anchoring assembly 23 includes a lateral movement assembly 231 and a drill arm 3. The lateral movement assembly 231 drives the drill arm 3 to move left and right. The second anchoring assembly 23 provides supplementary anchoring for the top roadway that was missed by the first anchoring assembly 12. The lateral movement assembly 231 straddles the top of the self-propelled tail assembly 2. In addition, the self-propelled tail assembly 2 is also equipped with a dust removal assembly 25, a water tank 26, and a pump station 27. Both the first chassis 11 and the second chassis 21 are driven by tracks, which facilitates the second chassis 21 to follow the first chassis 11.

[0038] See Figures 1 to 10The principle by which the loading unit 141 moves with the cutting assembly 13 is as follows: The cutting assembly 13 includes a cutting head 131 with a horizontal axis, a cutting arm 132, a sliding frame 133, a guide column 134, and front and rear telescopic cylinders 135. The cutting arm 132 is mounted on the sliding frame 133. The first pitch cylinder 136 drives the cutting arm 132 to pitch with the sliding frame 133 as the fulcrum. The front and rear telescopic cylinders 135 drive the sliding frame 133 to move back and forth along the guide column 134 with the first chassis 11 as the fulcrum, thereby driving the cutting head 131 to move back and forth through the cutting arm 132. The front transport unit 142 and the rear transport unit 143 are hinged together by a horizontal column 145. The 43 and the tail swing assembly 144 are hinged together by a vertical column 146. The second pitch cylinder 137 drives the rear transport unit 143 to pitch with the first chassis 11 as the fulcrum. The swing angle cylinder 138 drives the tail swing assembly 144 to swing along the vertical column 146 with the rear transport unit 143 as the fulcrum, so that the tail swing assembly 144 can be aligned with the crushing assembly 22. The tail of the sliding frame 133 is provided with a sliding groove 139. The front and rear telescopic cylinders 135 drive the sliding frame 133 to move back and forth. After the movement range of the sliding frame 133 exceeds the width of the sliding groove 139, the sliding frame 133 drives the first transport assembly 14 to move back and forth along the slide rail 4 through the sliding groove 139 and the horizontal column 145. The front end of the first chassis 11 is provided with a first lifting assembly 111 and a second lifting assembly 112; both the first lifting assembly 111 and the second lifting assembly 112 are provided with lifting cylinders 113 and slide blocks 114. Slide rails 4 are respectively provided on both sides of the front transport section 142. The slide rails 4 move back and forth along the slide blocks 114. The lifting cylinders 113 drive the slide blocks 114 to rise and fall, and make the front transport section 142 hinged to the horizontal column 145 for pitching. The slide rails 4 include a triangular support plate 41 and a horizontal slide rail 42 provided at the bottom of the support plate 41. Through the first lifting assembly 111 and the second lifting assembly 112, the loading section 141 and the front transport section 142 have pitch freedom to adapt to uneven roadway surfaces. Through the cooperation of the horizontal slide rails 42 and the slide blocks 114, under the drive of the front and rear telescopic cylinders 135, the loading section 141 and the front transport section 142 have the freedom to move back and forth, ensuring interception and transportation coordination.

[0039] The coordinated construction process for tunneling, anchoring, and transporting equipment used in coal roadways or semi-coal-rock roadways is as follows, employing the tunneling, anchoring, and transporting device for coal roadways or semi-coal-rock roadways described in this embodiment. (See [link to relevant documentation]). Figure 11Step S1: The tunneling and anchoring assembly and the self-propelled tail assembly advance synchronously. The cutting head contacts the cutting surface and is lifted to the highest point of the roadway. The tunneling direction is finely adjusted by the attitude adjustment assembly 15. Step S2: The front and rear telescopic cylinders 135 drive the cutting head 131 forward half a stroke (half the stroke of the front and rear telescopic cylinders 135, about 600mm). Then, the cutting head 131 cuts the cutting surface from top to bottom to the bottom of the roadway. Step S3: The cutting head 131 rises to the highest point, and the front and rear telescopic cylinders 135 drive the cutting. The head 131 advances for the remaining half stroke, and the cutting head 131 cuts the cutting surface from top to bottom to the bottom of the roadway; during steps S2 and S3, with the cooperation of the front and rear telescopic cylinders 135 and the chute, the loading part 141 moves in the front and rear direction following the cutting assembly 13, so that the loading part 141 can transfer the cut coal at any time; step S4: the front and rear telescopic cylinders 135 retract completely, and the next cutting advance is carried out according to steps S1-S3; the working principle of each step S1-S4 is described above and will not be repeated here.
