A tunneling machine auxiliary propulsion mechanism based on 5G technology

Abstract

The present application relates to the technical field of heading machine, especially to a heading machine auxiliary propulsion mechanism based on 5G technology, which aims to solve the problem that the existing heading machine auxiliary propulsion mechanism has no effective anti-skid component to prevent the heading machine from skidding when the telescopic component is retracted, thereby reducing the propulsion effect of the heading machine auxiliary propulsion mechanism. The heading machine auxiliary propulsion mechanism based on 5G technology comprises a propulsion part, an anti-skid part and a mounting plate. When the heading machine encounters a slope with a large slope in the tunnel and lacks power and skids, the propulsion part provides intermittent auxiliary propulsion force for the forward movement of the heading machine. During the time when the propulsion part does not provide auxiliary propulsion force, i.e. the propulsion part does not contact the slope, the anti-skid part contacts the surface of the slope, increases the ground adhesion, effectively prevents the heading machine from skidding, improves the propulsion effect of the propulsion part, and the auxiliary propulsion force provided by the propulsion part is superimposed with the power of the heading machine itself, so that the heading machine has enough power to move forward on the slope and effectively prevents skidding.

Description

Technical Field

[0001] This invention relates to the field of tunneling machine technology, and in particular to an auxiliary propulsion mechanism for tunneling machines based on 5G technology. Background Technology

[0002] Applying 5G communication technology to mining equipment to ensure efficient and safe production in mines has become a hot technical issue. In mechanized mining operations, tunneling machines are one of the main mining equipment. They mainly include cutting sections, shovel sections, first conveyors, body sections, traveling sections, and rear support sections. During operation, the cutting head of the cutting section cuts the cross-section of the roadway, the shovels collect the material, and the first conveyor transports the broken material out.

[0003] When tunneling machines are excavating in roadways, they often encounter sloping roadways or steep inclines. In such cases, the traveling mechanism of the tunneling machine often experiences insufficient power and slippage, which directly affects the overall operation of the machine and the safety of personnel in the roadway and surrounding working environment. Existing auxiliary propulsion mechanisms for tunneling machines include telescopic components and propulsion components. The propulsion component is connected to the output end of the telescopic component. When the telescopic component extends, the propulsion component applies a thrust to the traveling face of the tunneling machine, thereby giving the tunneling machine a tendency to move forward.

[0004] However, existing tunneling machine auxiliary propulsion mechanisms rely on the extension of telescopic components to assist in the propulsion of the tunneling machine. When the telescopic components retract, there are no effective anti-slip components to prevent the tunneling machine from slipping, which reduces the propulsion effect of the tunneling machine auxiliary propulsion mechanism. Summary of the Invention

[0005] This invention provides a tunneling machine auxiliary propulsion mechanism based on 5G technology to solve the problem that existing tunneling machine auxiliary propulsion mechanisms lack effective anti-slip components to prevent the tunneling machine from slipping when the telescopic components retract, thus reducing the propulsion effect of the tunneling machine auxiliary propulsion mechanism.

[0006] To achieve the above objectives, the present invention provides an auxiliary propulsion mechanism for a tunneling machine based on 5G technology, comprising a propulsion part, an anti-slip part, and a mounting plate. The mounting plate is fixedly installed on the lower rear part of the tunneling machine body, the propulsion part is installed on both sides of the lower end face of the mounting plate, and the anti-slip part is installed in the middle position of the lower end face of the mounting plate. The propulsion unit includes a pin, a swing arm, a first electric cylinder, a first telescopic rod, a connecting plate, a cam motor, a cam, a top plate, a movable rod, a spring, and a propulsion block. The connecting plate is fixedly installed on both sides of the lower end face of the mounting plate. The swing arm is rotatably connected to the connecting plate via the pin. The first electric cylinder is fixedly installed on the lower end face of the mounting plate. The lower end of the first telescopic rod on the first electric cylinder is movably installed on the swing arm. The cam motor is fixedly installed on the swing arm. The output shaft of the cam motor is fixedly connected to the cam. The cam abuts against the top plate. One end of the movable rod is fixedly connected to the top plate. The other end of the movable rod is connected to the propulsion block. The spring is fitted on the movable rod and is located inside the swing arm. The anti-slip part includes a second electric cylinder, a second telescopic rod, an anti-slip roller, and a ratchet mechanism. The ratchet mechanism includes a ratchet and a pawl. The second electric cylinder is fixedly installed at the middle position of the lower end face of the mounting plate. The lower end of the second telescopic rod of the second electric cylinder is rotatably connected to the anti-slip roller. Anti-slip teeth are provided on the middle circumference of the anti-slip roller. Ratchets are fixedly installed on both sides of the anti-slip roller. Pawls are rotatably installed on the second telescopic rod. The ratchet and pawl cooperate with each other.

[0007] In the aforementioned 5G-based tunneling machine auxiliary propulsion mechanism, optionally, the swing arm includes a swing arm body, a swing arm through hole, a top groove, a limiting hole, a side groove, and a side sliding hole. One end of the swing arm body is provided with a swing arm through hole, and the other end of the swing arm body is provided with a limiting hole. The swing arm through hole is rotatably connected to the connecting plate by a pin, and the limiting hole is slidably connected to the movable rod. The upper end of the swing arm body is provided with a top groove, and the two sides of the swing arm body are symmetrically provided with side sliding holes communicating with the top groove. The side of the swing arm body away from the center of the mounting plate is provided with a side groove.

[0008] In the aforementioned 5G-based tunneling machine auxiliary propulsion mechanism, a central hole may be provided on the main body of the swing arm.

[0009] In the aforementioned 5G-based tunneling machine auxiliary propulsion mechanism, optionally, the first telescopic rod includes a first telescopic rod body and a cylindrical bent rod. The upper end of the first telescopic rod body is connected to the first electric cylinder, and the lower end of the first telescopic rod body is fixedly connected to the cylindrical bent rod. The horizontal connecting rods at both ends of the cylindrical bent rod are inserted into the side sliding holes.

[0010] In the aforementioned 5G-based tunneling machine auxiliary propulsion mechanism, optionally, the top plate is rectangular, and the size of the top plate is larger than the end face size of the movable rod.

[0011] In the aforementioned 5G-based tunneling machine auxiliary propulsion mechanism, optionally, two ratchet mechanisms are provided, symmetrically arranged on both sides of the anti-slip roller.

[0014] The present invention provides a 5G-based auxiliary propulsion mechanism for a tunneling machine, comprising a propulsion unit, an anti-slip unit, and a mounting plate. The mounting plate is fixedly installed at the lower rear of the tunneling machine body. The propulsion unit is installed on both sides of the lower end face of the mounting plate, and the anti-slip unit is installed in the middle of the lower end face of the mounting plate. When the tunneling machine encounters a steep slope in the tunnel and experiences insufficient power or slippage, the propulsion unit provides intermittent auxiliary propulsion force for the tunneling machine's forward movement. During the time when the propulsion unit does not provide auxiliary propulsion force (i.e., when the propulsion unit is not in contact with the slope), the anti-slip unit contacts the slope surface, increasing ground adhesion and effectively preventing slippage of the tunneling machine, thus improving the propulsion effect of the propulsion unit. The auxiliary propulsion force provided by the propulsion unit is superimposed on the power of the tunneling machine itself, enabling the tunneling machine to have sufficient power to move forward on the slope and effectively preventing slippage.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be described in more detail below with reference to the accompanying drawings of the preferred embodiments. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] like Figures 1-4 , Figures 7-8 As shown, the present invention provides an auxiliary propulsion mechanism for a tunneling machine based on 5G technology, including a propulsion part 3, an anti-slip part 4, and a mounting plate 5. The mounting plate 5 is fixedly installed on the lower rear part of the tunneling machine body 1. The propulsion part 3 is installed on both sides of the lower end face of the mounting plate 5, and the anti-slip part 4 is installed in the middle position of the lower end face of the mounting plate 5. It should be noted that the propulsion section 3, the anti-slip section 4, and the mounting plate 5 are all located behind the tunneling machine track 2.

[0021] The propulsion unit 3 includes a pin 6, a swing arm 7, a first electric cylinder 8, a first telescopic rod 9, a connecting plate 10, a cam motor 11, a cam 12, a top plate 13, a movable rod 14, a spring 15, and a propulsion block 16. The connecting plate 10 is fixedly installed on both sides of the lower end face of the mounting plate 5. The swing arm 7 is rotatably connected to the connecting plate 10 through the pin 6. The first electric cylinder 8 is fixedly installed on the lower end face of the mounting plate 5. The lower end of the first telescopic rod 9 on the first electric cylinder 8 is movably installed on the swing arm 7. The cam motor 11 is fixedly installed on the swing arm 7. The output shaft of the cam motor 11 is fixedly connected to the cam 12. The cam 12 abuts against the top plate 13. One end of the movable rod 14 is fixedly connected to the top plate 13. The other end of the movable rod 14 is connected to the propulsion block 16. The spring 15 is fitted on the movable rod 14 and is located inside the swing arm 7. It should be noted that the extension of the first telescopic rod 9 drives the swing arm 7 to rotate around the pin 6 and gradually approach the slope. The rotation of the cam motor 11 drives the cam 12 to rotate. The cam 12 has a symmetrical structure. The rotating cam 12 presses against the top plate 13, which in turn drives the movable rod 14 to intermittently extend the swing arm 7. The movable rod 14 intermittently pushes the propulsion block 16 to contact the slope and apply a thrust to the slope. The direction of this thrust is at an acute angle to the plane of the slope. The reaction force of this thrust can be decomposed into components perpendicular to the slope and parallel to the slope. The component parallel to the slope is in the same direction as the tunneling machine, thus assisting the tunneling machine in propulsion. One end of the spring 15 is fixedly connected to the top plate 13, and the other end of the spring 15 is fixedly connected to the swing arm 7. When the rotating cam 12 presses against the top plate 13, the spring 15 is in its natural state and is not compressed when the minimum radius of the cam 12 contacts the top plate 13. When the maximum radius of the cam 12 contacts the top plate 13, the spring 15 is in its maximum compressed state.

[0022] The anti-slip part 4 includes a second electric cylinder 17, a second telescopic rod 18, an anti-slip roller 19, and a ratchet mechanism 20. The ratchet mechanism 20 includes a ratchet 21 and a pawl 22. The second electric cylinder 17 is fixedly installed at the middle position of the lower end face of the mounting plate 5. The lower end of the second telescopic rod 18 of the second electric cylinder 17 is rotatably connected to the anti-slip roller 19. Anti-slip teeth are provided on the middle circumference of the anti-slip roller 19. The ratchet 21 is fixedly installed on both sides of the anti-slip roller 19. The pawl 22 is rotatably installed on the second telescopic rod 18. The ratchet 21 and the pawl 22 cooperate with each other.

[0023] It should be noted that the ratchet mechanism 20 ensures that the anti-slip roller 19 can only roll forward of the tunneling machine and cannot roll backward. The second telescopic rod 18 of the second electric cylinder 17 extends, causing the anti-slip roller 19 to contact the slope. When the tunneling machine moves forward, the anti-slip roller 19 rolls forward accordingly. When the tunneling machine experiences insufficient power or slippage, the anti-slip roller 19 will not roll backward. The contact between the anti-slip roller 19 and the slope increases the ground adhesion, effectively preventing slippage of the tunneling machine and improving the propulsion effect of the propulsion unit 3.

[0024] The first electric cylinder 8, the cam motor 11, and the second electric cylinder 17 are all connected to the controller signal. The controller is located in the control room on the ground. A radar speed sensor is installed in the tunnel. A camera device is installed on the main body 1 of the tunneling machine, pointing at the tunneling machine track 2 to record the real-time operation of the track 2. Both the radar speed sensor and the camera device are connected to the controller signal. The radar speed sensor monitors the tunneling machine's travel speed in real time and sends the travel speed information to the controller in real time. In the initial state, the cam motor 11 does not rotate, the first telescopic rod 9 of the first electric cylinder 8 retracts, and the second telescopic rod 18 of the second electric cylinder 17 retracts, so that the propulsion part 3 and the anti-slip part 4 are both away from the ground and do not contact the ground. When the radar speed sensor detects that the tunneling machine has stalled, the radar speed sensor sends the monitored information to the controller. The signal is sent to the controller. The controller, combined with the real-time movement of the tunneling machine's tracks 2 captured by the camera device, determines that the tunneling machine is experiencing insufficient power or slippage in the tunnel. The controller then sends commands to the first electric cylinder 8, the cam motor 11, and the second electric cylinder 17, which are connected to it. The second telescopic rod 18 of the second electric cylinder 17 extends, causing the anti-slip roller 19 to contact the slope. At the same time, the first telescopic rod 9 of the first electric cylinder 8 extends, causing the swing arm 7 to rotate around the pin 6 and gradually approach the slope. After reducing the distance between the propulsion block 16 and the slope, the first electric cylinder 8 stops moving. Subsequently, the cam motor 11 drives the cam 12 to press against the top plate 13, which in turn causes the movable rod 14 to intermittently extend the swing arm 7. The movable rod 14 intermittently pushes the propulsion block 16 to contact the slope and apply thrust to the slope, thus assisting the tunneling machine in its propulsion.

[0025] like Figure 2 , Figure 5As shown, the swing arm 7 includes a swing arm body 701, a swing arm through hole 702, a top groove 703, a limiting hole 704, a side groove 706, and a side sliding hole 707. One end of the swing arm body 701 is provided with the swing arm through hole 702, and the other end of the swing arm body 701 is provided with the limiting hole 704. The swing arm through hole 702 is rotatably connected to the connecting plate 10 through a pin 6. The limiting hole 704 is slidably connected to the movable rod 14. The upper end of the swing arm body 701 is provided with the top groove 703. The two sides of the swing arm body 701 are symmetrically provided with side sliding holes 707 communicating with the top groove 703. The side of the swing arm body 701 away from the center of the mounting plate 5 is provided with the side groove 706.

[0026] It should be noted that the cam motor 11, cam 12, top plate 13, spring 15 and one end of movable rod 14 are located in side groove 706.

[0027] like Figure 5 As shown, a center hole 705 is provided on the main body 701 of the swing arm. It should be noted that the center hole 705 is connected to the top groove 703. While ensuring the support strength, the center hole 705 on the main body of the swing arm 701 can reduce the weight of the swing arm 7.

[0028] like Figures 5-6 As shown, the first telescopic rod 9 includes a first telescopic rod body 901 and a cylindrical bent rod 902. The upper end of the first telescopic rod body 901 is connected to the first electric cylinder 8, and the lower end of the first telescopic rod body 901 is fixedly connected to the cylindrical bent rod 902. The horizontal connecting rods 903 at both ends of the cylindrical bent rod 902 are inserted into the side sliding holes 707.

[0029] It should be noted that the horizontal connecting rod 903 can slide within the sliding hole 707 and can also rotate within the sliding hole 707.

[0030] like Figure 2 As shown, the top plate 13 is rectangular, and the size of the top plate 13 is larger than the end face size of the movable rod 14.

[0031] It should be noted that the size of the top plate 13 is larger than the end face size of the movable rod 14, which effectively prevents the movable rod 14 from slipping off the swing arm 7, and at the same time can restrict the spring 15 between the swing arm 7 and the top plate 13.

[0032] like Figures 1-3 As shown, two ratchet mechanisms 20 are provided, symmetrically arranged on both sides of the anti-slip roller 19.

[0033] It should be noted that ratchet mechanisms 20 are symmetrically arranged on both sides of the anti-slip roller 19 to effectively prevent the anti-slip roller 19 from reversing.

[0034] like Figures 1-3 As shown, the connecting plates 10 are arranged in pairs.

[0035] It should be noted that the connecting plates 10 are arranged in pairs, and the swing arm 7 is rotatably installed between a pair of connecting plates 10 to improve the support strength of the swing arm 7.

[0036] like Figures 2-3 As shown, the movable rod 14 is hinged to the propulsion block 16.

[0037] It should be noted that during the auxiliary propulsion process after the propulsion block 16 contacts the slope, it can adaptively rotate around the end of the movable rod 14 according to the specific conditions of the thrust and the force point, so as to more reliably transmit the reaction force of the slope to the auxiliary propulsion mechanism and the tunneling machine.

[0038] The present invention provides a 5G-based auxiliary propulsion mechanism for a tunneling machine, comprising a propulsion unit 3, an anti-slip unit 4, and a mounting plate 5. The mounting plate 5 is fixedly installed on the lower rear of the tunneling machine body 1. The propulsion unit 3 is installed on both sides of the lower end face of the mounting plate 5, and the anti-slip unit 4 is installed in the middle of the lower end face of the mounting plate 5. When the tunneling machine encounters a steep slope in the tunnel and experiences insufficient power or slippage, the propulsion unit 3 provides intermittent auxiliary propulsion force for the tunneling machine's forward movement. During the time when the propulsion unit 3 does not provide auxiliary propulsion force (i.e., when the propulsion unit 3 is not in contact with the slope), the anti-slip unit 4 contacts the slope surface, increasing ground adhesion and effectively preventing slippage of the tunneling machine, thereby improving the propulsion effect of the propulsion unit 3. The auxiliary propulsion force provided by the propulsion unit 3 is superimposed on the power of the tunneling machine itself, enabling the tunneling machine to have sufficient power to move forward on the slope and effectively preventing slippage.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
