Technical Field

[0001] This invention relates to the field of coal mine facilities, and more particularly to a coal mine tunneling structure, track, and method. Background Technology

[0002] A roadheader, short for a fully mechanized tunneling machine, is a type of integrated mechanized equipment that combines tunneling, rock loading, and coal transportation functions. Roadheaders are particularly common in coal mining operations.

The above-mentioned existing technology has a long working time, resulting in low work efficiency. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of the prior art by proposing a coal mine fully mechanized tunneling structure, track, and method.

[0007] Preferably, the track-laying component includes a first threaded rod rotatably mounted on the lower end of the chassis, a second threaded rod mounted on the lower end of the chassis, the second threaded rod being located directly behind the first threaded rod, the threads at both ends of the first threaded rod and the threads at both ends of the second threaded rod being symmetrically arranged, a servo motor mounted on the upper end of the chassis, and the output end of the servo motor being connected to the middle of the first threaded rod and the middle of the second threaded rod.

[0008] Preferably, two primary support frames are symmetrically installed below the vehicle frame. Two secondary support frames extend outward from the front ends of the two primary support frames. The primary support frames and secondary support frames are integrally formed. A motor frame is fixedly installed at the lower end of the servo motor. The end of the motor frame is fixedly connected to the vehicle frame. Three pulleys are coaxially embedded in the middle of the outer surface of the primary threaded rod, the middle of the outer surface of the secondary threaded rod, and the output end of the servo motor. A synchronous belt connects the three pulleys. Rod frames are rotatably embedded at both ends of the primary threaded rod and both ends of the secondary threaded rod. The ends of the rod frames are fixedly connected to the vehicle frame.

[0009] Preferably, two No. 2 threaded sleeves are symmetrically screwed onto the outer surface of the No. 1 threaded rod, and the two No. 2 threaded sleeves are respectively fixedly connected to the upper ends of the two No. 2 bearing frames. Two No. 1 threaded sleeves are symmetrically screwed onto the outer surface of the No. 2 threaded rod, and the two No. 1 threaded sleeves are respectively fixedly connected to the upper ends of the two No. 1 bearing frames. Multiple laying wheels are linearly arrayed on both sides of the No. 1 bearing frame, and multiple guide wheels are obliquely arranged below the No. 2 bearing frame.

[0010] Preferably, upper wheel frames are fixedly installed on both sides of the first bearing frame, and a lower wheel frame is provided directly below the upper wheel frame. A connecting block is embedded between the lower wheel frame and the upper wheel frame. The laying wheel is installed between the upper wheel frame and the lower wheel frame. The laying wheel and the connecting block are staggered. Two bearing wheel frames are symmetrically installed at the lower end of the second bearing frame. The guide wheel is installed between the two bearing wheel frames. A concave frame is fixedly installed on the side of the second bearing frame. The two ends of the concave frame are fixedly connected to the two bearing wheel frames respectively.

[0011] Preferably, the detection component includes a prism installed at the rear of the vehicle frame. Two limiting caps are respectively embedded at both ends of the prism. Two push rings are symmetrically and elastically installed on the outer surface of the prism. A connecting wheel frame is installed at the lower end of the push ring. A measuring wheel is installed inside the connecting wheel frame. A measuring ruler is set directly above the prism. An indicator plate is fixedly installed on the upper end face of the push ring. A groove is opened on the inner side of the measuring ruler. The indicator plate fits through the inside of the groove. The side of the indicator plate is coplanar with the wheel edge of the measuring wheel.

[0012] Preferably, an extension frame is fixedly installed at the rear end of the frame, and a fixing ring is embedded at the end of the extension frame. The fixing ring is embedded in the middle of the outer surface of the prism. A tightening spring is wound around the outside of the prism.

An L-shaped frame is fixedly installed on the upper end face of the extension frame, and the end of the L-shaped frame is fixedly connected to the measuring ruler.

[0013] It also provides a method for using a coal mine tunneling structure and track, including the following steps: S1: Use a tunneling machine to excavate and widen the sidewalls of the mine tunnel;

[0014] S2: During the tunneling process, two rails are laid using track-laying components;

[0015] S3: After laying, the spacing between the two rails is measured in real time using testing equipment to check whether it meets the standard.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. With the installation of the track-laying components, when the roadheader is excavating and widening the sidewall of the mine tunnel, the chassis will be pulled by the roadheader. At this time, the guide wheels on the two outward-inclined No. 2 bearing frames will push the two rails placed on the mine tunnel surface, allowing the two separately placed rails to converge inward. The rails converging inward pass between the two laying wheels on the No. 1 bearing frame, so that the converged rails are laid in a straight line under the limit of the two laying wheels. This process is repeated to lay rails while excavating, reducing working time and improving work efficiency.

[0018] 2. Furthermore, the servo motor can be activated to synchronously drive the No. 2 threaded rod and the No. 1 threaded rod to rotate via a synchronous belt. This allows the two No. 2 threaded sleeves screwed onto the No. 1 threaded rod to drive the two No. 2 bearing frames to move towards each other, and the two No. 1 threaded sleeves screwed onto the No. 2 threaded rod to drive the two No. 1 bearing frames to move towards each other. This allows for fine-tuning of the distance between the two No. 1 bearing frames and the two No. 2 bearing frames, that is, fine-tuning of the distance between the two laid rails, so that the distance between the two laid rails reaches the preset distance, thereby meeting the usage requirements.

[0019] 3. With the set detection components, after the rails are laid, the two measuring wheels on the two push rings will roll against the opposite surfaces of the two rails under the push of the tightening spring. At this time, by observing the values ​​indicated on the measuring ruler by the opposite surfaces of the two indicator plates, it can be determined whether the spacing between the two rails is qualified. This achieves the purpose of real-time detection of the spacing of the laid rails, thereby improving the convenience of the detection. Attached Figure Description

[0027] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0028] As described in the background section, during the process of tunneling and widening the sidewalls of a mine, the laying of rails can only be carried out after the tunneling work of the roadheader is completed, which leads to low work efficiency.

[0029] To solve this technical problem, the present invention provides a coal mine tunneling structure and track, which are applied to coal mine tunneling.

[0030] Example 1

[0031] like Figures 1-6The diagram illustrates a coal mine roadway structure and track, including a roadheader 1. A connecting frame 2 is fixedly installed at the rear end of the roadheader 1. A seat 3 is fixedly installed at the rear end of the connecting frame 2. A frame 4 is fixedly installed at the rear end of the seat 3. Track laying components are mounted on the frame 4, and a detection component is mounted at the rear end of the frame 4. Load-bearing rear wheels 5 are installed at the rear edges of both sides of the frame 4, and load-bearing front wheels 6 are installed at the lower end of the seat 3. The frame 4 moves with the assistance of the load-bearing front wheels 6 and the load-bearing rear wheels 5. The roadheader 1 mainly consists of a traveling mechanism, a working mechanism, a loading mechanism, and a transfer mechanism. As the traveling mechanism advances, the cutting head in the working mechanism continuously breaks the rock and transports the broken rock away. It has advantages such as safety, high efficiency, and good roadway quality, but it is costly, complex in structure, and experiences significant wear and tear.

[0032] The testing component includes a prism 16 installed at the rear of the frame 4. Two limit caps 17 are respectively inlaid at both ends of the prism 16. Two push rings 18 are symmetrically and elastically installed on the outer surface of the prism 16. A connecting wheel frame 20 is installed at the lower end of the push rings 18. The limit caps 17 prevent the push rings 18 from detaching from the prism 16. A measuring wheel 21 is installed inside the connecting wheel frame 20. A measuring ruler 7 is set directly above the prism 16. The connecting wheel frame 20 supports the measuring wheel 21. An indicator plate 22 is fixedly installed on the upper end face of the push rings 18. The indicator plate 22 indicates the value on the measuring ruler 7. A groove 23 is opened on the inner side of the measuring ruler 7. The indicator plate 22 fits through the inside of the groove 23. The side of the indicator plate 22 is coplanar with the wheel edge of the measuring wheel 21. When the measuring wheel 21 rolls against the opposite surfaces of the two rails, the opposite surfaces of the two indicator plates 22 are coplanar with the opposite surfaces of the two rails.

[0033] With the set detection components, after the rails are laid, the two measuring wheels 21 on the two push rings 18 will roll against the opposite surfaces of the two rails under the push of the tightening spring 19. At this time, by observing the values ​​indicated on the measuring ruler 7 by the opposite surfaces of the two indicator plates 22, it can be determined whether the spacing between the two rails is qualified. This achieves the purpose of real-time detection of the spacing of the laid rails, thereby improving the convenience of the detection.

[0034] An extension frame 13 is fixedly installed at the rear end of the frame 4. A fixing ring 15 is embedded at the end of the extension frame 13. The fixing ring 15 is embedded in the middle of the outer surface of the prism 16. The extension frame 13 and the fixing ring 15 serve to fix the prism 16. A tensioning spring 19 is wound around the outside of the prism 16. The tensioning spring 19 serves to tighten the measuring wheel 21 and make the measuring wheel 21 close to the rail. The tensioning spring 19 is located between the side of the push ring 18 and the side of the fixing ring 15. An L-shaped frame 14 is fixedly installed on the upper end face of the extension frame 13. The end of the L-shaped frame 14 is fixedly connected to the measuring ruler 7. The L-shaped frame 14 serves to fix the measuring ruler 7.

[0035] Example 2

[0036] The solution in Example 1 will be further described below with reference to its specific working method.

[0037] like Figures 1-6 The diagram shows a coal mine tunneling structure and track, including a tunneling machine 1, a connecting frame 2 fixedly installed at the rear end of the tunneling machine 1, a seat 3 fixedly installed at the rear end of the connecting frame 2, a frame 4 fixedly installed at the rear end of the seat 3, a track laying component installed on the frame 4, a detection component installed at the rear end of the frame 4, load-bearing rear wheels 5 installed at the rear edges on both sides of the frame 4, and load-bearing front wheels 6 installed at the lower end of the seat 3.

[0038] The track-laying components include a first threaded rod 24 rotatably mounted on the lower end of the frame 4, and a second threaded rod 28 mounted on the lower end of the frame 4. The second threaded rod 28 is located directly behind the first threaded rod 24. The threads at both ends of the first threaded rod 24 and the threads at both ends of the second threaded rod 28 are symmetrically arranged, which can drive the two first bearing frames 9 and the two second bearing frames 10 to move towards each other when rotating. A servo motor 26 is mounted on the upper end of the frame 4. The output end of the servo motor 26 is connected to the middle part of the first threaded rod 24 and the middle part of the second threaded rod 28. The servo motor 26 plays the role of driving the first threaded rod 24 and the second threaded rod 28 to rotate synchronously.

[0039] Furthermore, the servo motor 26 can be activated to synchronously drive the second threaded rod 28 and the first threaded rod 24 to rotate via the synchronous belt 8. This allows the two second threaded sleeves 34 screwed onto the first threaded rod 24 to drive the two second bearing frames 10 to move towards each other, and the two first threaded sleeves 29 screwed onto the second threaded rod 28 to drive the two first bearing frames 9 to move towards each other. This allows for fine-tuning of the distance between the two first bearing frames 9 and the distance between the two second bearing frames 10, that is, fine-tuning of the distance between the two laid rails, so that the distance between the two laid rails can reach the preset distance, thereby meeting the usage requirements.

[0040] Two primary support frames 9 are symmetrically installed below the frame 4. The front ends of the two primary support frames 9 extend outwards to form two secondary support frames 10. The primary support frames 9 and secondary support frames 10 are integrally formed. A motor frame 27 is fixedly installed at the lower end of the servo motor 26. The end of the motor frame 27 is fixedly connected to the frame 4. The motor frame 27 serves to fix the servo motor 26. Three pulleys 25 are coaxially embedded in the middle of the outer surface of the primary threaded rod 24, the middle of the outer surface of the secondary threaded rod 28, and the output end of the servo motor 26. A synchronous belt 8 is connected between the three pulleys 25. The pulleys 25 and the synchronous belt 8 serve to connect and transmit power. Both ends of the primary threaded rod 24 and both ends of the secondary threaded rod 28 are rotatably embedded with a rod holder 30. The end of the rod holder 30 is fixedly connected to the frame 4. The rod holder 30 serves to connect the primary threaded rod 24 and the secondary threaded rod 28.

[0041] Two threaded sleeves 34 are symmetrically screwed onto the outer surface of the first threaded rod 24. The two threaded sleeves 34 are fixedly connected to the upper ends of the two second bearing frames 10 respectively. The threaded sleeves 34 cooperate with the first threaded rod 24. Two threaded sleeves 29 are symmetrically screwed onto the outer surface of the second threaded rod 28. The two threaded sleeves 29 are fixedly connected to the upper ends of the two first bearing frames 9 respectively. The threaded sleeves 29 cooperate with the second threaded rod 28. Multiple laying wheels 12 are linearly arrayed on both sides of the first bearing frame 9. Multiple guide wheels 11 are arranged obliquely below the second bearing frame 10. The guide wheels 11 push the rails, allowing the two separately placed rails to converge inward. The laying wheels 12 straighten the converged rails.

[0042] Upper wheel frames 31 are fixedly installed on both sides of the first support frame 9. A lower wheel frame 32 is set directly below the upper wheel frame 31. A connecting block 33 is embedded between the lower wheel frame 32 and the upper wheel frame 31. The connecting block 33 serves to fix the upper wheel frame 31 and the lower wheel frame 32 together. The laying wheel 12 is installed between the upper wheel frame 31 and the lower wheel frame 32. The laying wheel 12 and the connecting block 33 are staggered. The upper wheel frame 31 and the lower wheel frame 32 serve to support the laying wheel 12. Two support wheel frames 36 are symmetrically installed at the lower end of the second support frame 10. The guide wheel 11 is installed between the two support wheel frames 36. A concave frame 35 is fixedly installed on the side of the second support frame 10. The two ends of the concave frame 35 are fixedly connected to the two support wheel frames 36 respectively. The support wheel frames 36 serve to support the guide wheel 11. The concave frame 35 serves to fix the two support wheel frames 36 together.

[0043] Example 3

[0044] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0045] like Figures 1-6 The diagram shows a coal mine tunneling structure and track, including a tunneling machine 1, a connecting frame 2 fixedly installed at the rear end of the tunneling machine 1, a seat 3 fixedly installed at the rear end of the connecting frame 2, a frame 4 fixedly installed at the rear end of the seat 3, a track laying component installed on the frame 4, a detection component installed at the rear end of the frame 4, load-bearing rear wheels 5 installed at the rear edges on both sides of the frame 4, and load-bearing front wheels 6 installed at the lower end of the seat 3.

[0046] It also provides a method for using a coal mine tunneling structure and track, including the following steps: S1: Use a tunneling machine to excavate and widen the sidewalls of the mine tunnel;

[0047] S2: During the tunneling process, two rails are laid using track-laying components;

[0048] S3: After laying, the spacing between the two rails is measured in real time using testing equipment to check whether it meets the standard.

[0049] Example 4

[0050] The solutions in Embodiments 1, 2, and 3 will be further described below with reference to their specific working methods.

[0051] During operation, the servo motor 26 can be activated to drive the second threaded rod 28 and the first threaded rod 24 to rotate via the synchronous belt 8. This allows the two second threaded sleeves 34 screwed onto the first threaded rod 24 to drive the two second bearing frames 10 to move towards each other, and the two first threaded sleeves 29 screwed onto the second threaded rod 28 to drive the two first bearing frames 9 to move towards each other. This allows for fine-tuning of the distance between the two first bearing frames 9 and the distance between the two second bearing frames 10, i.e., fine-tuning the distance between the two laid rails, so that the distance between the two laid rails reaches the preset distance. Subsequently, the roadheader 1 works to excavate and widen the sidewall of the mine tunnel, and the chassis 4 is pulled by the roadheader 1 to move. At this time, it tilts outward. The guide wheels 11 on the two second-bearing frames 10 will push the two rails placed on the mine road surface, allowing the two separately placed rails to converge inward. At this time, the rails converge inward and pass between the two laying wheels 12 on the first-bearing frame 9, so that the converged rails are laid in a straight line under the limit of the two laying wheels 12. This process is repeated while digging and laying. After the rails are laid, the two measuring wheels 21 on the two pushing rings 18 will roll against the opposite surfaces of the two rails under the push of the tightening spring 19. At this time, the value indicated on the measuring ruler 7 on the opposite side of the two indicator plates 22 can be observed to determine whether the spacing between the two rails is qualified, thus achieving the purpose of real-time detection of the spacing of the laid rails.
