Description

TECHNICAL FIELD

[0001] The present application relates to the field of coal machine equipment, and particularly belongs to a step self-moving machine tail, a step self-moving machine tail deviation adjusting device and method. BACKGROUND

[0002] In recent years, as a large coal production and consumption country, the state has put forward higher requirements for energy consumption, and coal consumption accounts for a large proportion in energy consumption. Many new devices are used in the process of coal mining, among which the new belt self-moving machine tail brings a new direction.

[0003] In the process of tunneling, the tunneling efficiency is a key factor that restricts the advancing speed of tunneling. In the actual tunneling process, as the tunneling working face is continuously pushed forward, the equipment of the working face needs to be moved.

[0004] The tail end of the belt conveyor is connected with the tunneling machine, and the moving speed of the belt conveyor tail moving to the target position seriously restricts the advancing speed of the working face, and even affects the production efficiency of the coal mining working face. Moreover, due to the limitation of geographical and geological conditions, the moving space of the belt conveyor tail is limited, which causes difficulty in moving. The current situation of coal mines is that the tail moving speed is slow, a large amount of manpower is needed for each movement, and a large amount of manpower input increases the production risk to a certain extent. SUMMARY

[0005] The purpose of the present application is to provide a step self-moving machine tail, a step self-moving machine tail deviation adjusting device and method, which can improve the rapid and accurate movement of the belt conveyor tail, reduce the personnel input, save the construction cost and ensure the safety of personnel.

[0006] In order to achieve the above purpose, the present application provides the following technical scheme:

[0007] A step self-moving machine tail deviation adjusting device for a step self-moving machine tail, comprising:

[0008] A support rail, the bottom of the support rail is provided with a support surface for generating static friction with the ground, and the upper end of the support rail is provided with a guide rail;

[0009] A lifting mechanism for lifting the end of the step self-moving machine tail, the lifting mechanism is located above the support rail, the telescopic end of the lifting mechanism is connected with a first sliding block of the guide rail, and the body of the lifting mechanism is connected with the step self-moving machine tail;

[0010] A driving mechanism, the body of the driving mechanism is fixedly connected with the body of the support rail, the driving end of the driving mechanism is in transmission connection with the first sliding block, and the driving direction of the driving mechanism is parallel to the guiding direction of the guide rail.

[0011] The lifting mechanism has a first fixed connection part on its main body for fixedly connecting with the main body of the stepping self-moving machine tail, and the driving end of the lifting mechanism has a second fixed connection part for fixedly connecting with the first slider.

[0012] When the drive mechanism drives the first slider to move along the track direction of the guide rail, the first fixed connection part and the second fixed connection part drive the body of the lifting mechanism, the first slider and the stepping self-moving tail to move synchronously.

[0013] The telescopic end of the lifting mechanism is fixedly connected to the first slider of the guide rail;

[0014] The body of the lifting mechanism is fixedly connected to the tail of the stepping self-moving machine.

[0015] The lifting mechanism has multiple components, and each lifting mechanism has a connecting frame for fixing to the tail of the stepping self-propelled machine. The main body of each lifting mechanism is fixed inside the connecting frame.

[0016] The upper end of the support rail has a through groove, which is the track of the guide rail;

[0017] The shape of the first slider of the guide rail matches the through groove, and the first slider is slidably connected to the through groove;

[0018] A first limiting member is provided above the through groove. The first limiting member is connected to the support rail. The first slider is limited between the first limiting member and the through groove. The first slider and one surface of the first limiting member are in contact with each other. The first slider and the first limiting member are slidably connected.

[0019] Compared with existing technologies, the self-propelled walking machine tail-alignment device provided by this invention utilizes a cooperating lifting mechanism and support rail during alignment. The lifting mechanism raises the end of the self-propelled walking machine tail, and the support rail, via its upper guide rail, allows the raised end of the self-propelled walking machine tail to slide relative to the ground. During alignment, the drive mechanism moves the first slider of the guide rail, which in turn moves the entire lifting mechanism. The lifting mechanism simultaneously causes the raised end of the self-propelled walking machine tail to slide, adjusting the direction of the tail-end and ultimately completing the alignment adjustment. This invention can quickly adjust the offset direction of the self-propelled walking machine tail, reducing manpower input, saving construction costs, and ensuring personnel safety.

[0020] The present invention also provides a stepping self-moving tail, wherein the end of the stepping self-moving tail is connected to the stepping self-moving tail adjustment device as described above, and the adjustment direction of the stepping self-moving tail adjustment device intersects with the movement direction of the stepping self-moving tail.

[0021] Compared with the prior art, the beneficial effects of the stepping self-moving tail provided by the present invention are the same as the beneficial effects of the stepping self-moving tail adjustment device described in the above technical solution, and will not be repeated here.

[0022] The present invention also provides a method for adjusting the tail of a stepping self-moving machine, comprising:

[0023] The end of the self-propelled stepping tail is lifted by a lifting mechanism, and the body of the lifting mechanism is fixedly installed with the body of the self-propelled stepping tail.

[0024] A support rail is installed at one end of the lifting mechanism so that the lifting mechanism can slide relative to the ground;

[0025] The position of the lifting mechanism is adjusted by driving the lifting mechanism to adjust the position of the tail end of the stepping self-propelled machine, which is in the raised state.

[0026] Compared with the prior art, the beneficial effects of the stepping self-moving tail adjustment method provided by the present invention are the same as the beneficial effects of the stepping self-moving tail adjustment device described in the above technical solution, and will not be repeated here.

[0042] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0043] The present invention will be further described in detail below with reference to specific embodiments. These descriptions are for explanation purposes only and are not intended to limit the scope of the invention.

[0044] Please refer to Figure 1 This diagram illustrates a three-dimensional structure of the self-propelled machine tail alignment device installed at the front end of the self-propelled machine tail, wherein the self-propelled machine tail alignment device is fixedly connected to the self-propelled machine tail by bolts. To avoid the self-propelled machine tail alignment device affecting normal passage in the mine shaft, the self-propelled machine tail alignment device is installed between the two main guide rails 7 at the front end of the self-propelled machine tail, as shown below. Figure 1 and Figure 2 As shown.

[0045] like Figure 3 and Figure 4 As shown, the self-propelled stepping machine tail tilting device of the present invention includes a support rail 1, a lifting mechanism 2 and a driving mechanism 3.

[0046] The bottom of the aforementioned support rail 1 is provided with a support surface 14 for generating static friction with the ground. The main function of the support surface 14 is to ensure that the support rail 1 can stably grip the ground when the drive mechanism 3 moves one end of the stepping self-propelled machine. The support rail 1 provides a stable point of force, increasing the stability of the stepping self-propelled machine's tail adjustment. Figure 5 As shown, the support surface 14 at the bottom of the support rail 1 has multiple mutually spaced trapezoidal groove structures and trapezoidal protrusion structures. The trapezoidal protrusion structures can penetrate deep into the ground, and the trapezoidal groove structures can accommodate the upper soft soil layer, so that the support rail 1 can stably grip the ground when working on relatively soft ground.

[0047] The upper end of support rail 1 is equipped with a guide rail, such as... Figure 1 As shown, the upper end of the support rail 1 has a through groove, which is the track 11 of the guide rail. The shape of the first slider 12 of the guide rail matches the through groove, and the first slider 12 is slidably connected to the through groove, as shown. Figure 5 As shown, a first limiting member 13 is provided above the through groove. The first limiting member 13 is connected to the support rail 1. The first slider 12 is limited between the first limiting member 13 and the through groove. The first slider 12 and one surface of the first limiting member 13 are in contact with each other. The first slider 12 and the first limiting member 13 are slidably connected.

[0048] In one example, such as Figure 5As shown, the cross-section of the through groove on the support rail 1 is rectangular, the cross-section of the first slider 12 is trapezoidal, and the cross-section of the first limiting member 13 is L-shaped. The first slider 12 is disposed in the through groove, and the two L-shaped first limiting members 13 hold the first slider 12 in place within the through groove. Furthermore, the two L-shaped first limiting members 13 are fixedly connected to the support rail 1. The resulting effect is that the first slider 12 can slide on the support rail 1. Simultaneously, when the first slider 12 is lifted, the support rail 1 can also be lifted along with it. This design allows the entire self-propelled stepping tail section adjustment device to adjust its position as the stepping tail section moves forward, eliminating the need for continuous manual handling of the support rail 1, saving manpower, and reducing the possibility of operator injury.

[0049] In another example, such as Figure 6 As shown, the first slider 12 has a trapezoidal cross-section, and the first limiting member 13 has a triangular cross-section. The two triangular first limiting members 13 hold the first slider 12 in the through groove. The two triangular first limiting members 13 are fixedly connected to the support rail 1. The result is that the first slider 12 can slide on the support rail 1. At the same time, when the first slider 12 is lifted, the support rail 1 can also be lifted along with the first slider 12. This design allows the entire stepping self-propelled tail tilting device to adjust its position as the stepping self-propelled tail moves forward, eliminating the need for manual handling of the support rail 1, saving manpower and reducing the possibility of operator injury.

[0050] Therefore, support rail 1 provides stable support and guidance, offering a stable fulcrum for the stepping self-propelled tail that needs to be lifted. It also provides a point of application for the drive mechanism 3 when it moves the stepping self-propelled tail in the desired direction, transferring the inertial force of the tail to the ground when it stops. Ultimately, this ensures stable tail-to-tail adjustment in a specific direction, reducing vibration during adjustment.

[0051] The aforementioned lifting mechanism 2 is used to lift the end of the self-propelled stepping tail. The lifting mechanism 2 is located above the support rail 1. The telescopic end of the lifting mechanism 2 is connected to the first slider 12 of the guide rail, and the body of the lifting mechanism 2 is connected to the self-propelled stepping tail. When lifting the end of the self-propelled stepping tail, the telescopic end of the lifting mechanism 2 extends, increasing the relative distance between the first slider 12 on the guide rail and the self-propelled stepping tail. After the support surface 14 at the bottom of the support rail 1 is grounded, the support rail 1 remains stationary under the support of the ground. Then, as the telescopic end continues to extend, one end of the self-propelled stepping tail is slowly lifted. Because the lifting mechanism 2 is connected to the first slider 12, and the first slider 12 can slide in the guiding direction of the guide rail, when moving the self-propelled stepping tail, only the friction between the first slider 12 and the rail 11 needs to be overcome, significantly reducing the required moving power. The aforementioned lifting mechanism 2 can be implemented in various ways, such as a combination of a telescopic cylinder, a ball screw nut pair and a motor, or a jack.

[0052] In practical use, the lifting mechanism 2 has a first fixed connection part 21 on its main body for fixed connection with the main body of the stepping self-propelled tail, and a second fixed connection part 22 on its drive end for fixed connection with the first slider 12. When the drive mechanism 3 drives the first slider 12 to move along the guide direction of the guide rail 11, the first fixed connection part 21 and the second fixed connection part 22 drive the main body of the lifting mechanism 2, the first slider 12 and the stepping self-propelled tail to move synchronously.

[0053] like Figure 2 As shown, the first fixed connection part 21 is used to fix the body of the lifting mechanism 2 and the body of the stepping self-moving tail to each other. Figure 1 As shown, the second fixed connection part 22 is used to fix the driving end of the lifting mechanism 2 to the first slider 12, making the body of the lifting mechanism 2, the first slider 12, and the stepping self-propelled tail a whole. Finally, with the connection of the first fixed connection part 21 and the second fixed connection part 22, when the driving mechanism 3 drives the first slider 12 to move, the first slider 12 can drive the lifting mechanism 2 and the raised end of the stepping self-propelled tail to move together. The first fixed connection part 21 can adopt various embodiments; for example, the first fixed connection part 21 is a bolt or a welded part formed by welding. The second fixed connection part 22 can adopt various embodiments; for example, the first fixed connection part 21 is a bolt or a welded part formed by welding.

[0054] The main body of the aforementioned drive mechanism 3 is fixedly connected to the main body of the support rail 1. The drive end of the drive mechanism 3 is connected to the first slider 12 via a transmission connection. The driving direction of the drive mechanism 3 is parallel to the guiding direction of the guide rail. The drive mechanism 3 is used to drive the first slider 12 to slide back and forth along the guide rail on the support rail 1, and to drive the tail of the stepping self-propelled machine to move for adjustment. The drive mechanism 3 can be implemented in various ways, such as using a hydraulic cylinder, a linear drive mechanism combining a ball screw and nut pair and a servo motor, or a pneumatic cylinder.

[0055] Please refer to Figure 1 To more stably lift the tail of the self-propelled stepping machine and increase the overall lifting force, multiple lifting mechanisms 2 can be used simultaneously. Each lifting mechanism 2 has a connecting frame 23 for fixing it to the tail of the self-propelled stepping machine, and the main body of each lifting mechanism 2 is fixed within the connecting frame 23. Using the connecting frame 23 expands the number of lifting mechanisms 2 that can be used and facilitates the interconnection of multiple lifting mechanisms 2 with the tail of the self-propelled stepping machine.

[0056] When adjusting the tail section of the stepping self-propelled machine during operation, the main guide rail 7 of the tail section should be adjusted to a suspended state. Please refer to... Figure 1 The lifting mechanism 2 extends, lowering the support rail 1 until it contacts the ground. Then, the lifting mechanism 2 continues to extend, and due to the support of the support rail 1, it lifts one end of the stepping self-propelled machine's tail. After the stepping self-propelled machine's tail is lifted, the telescopic end of the lifting mechanism 2 locks, maintaining the raised state of the stepping self-propelled machine's tail.

[0057] Then, the drive mechanism 3 moves the first slider 12 to the left or right, and the first slider 12 moves one end of the entire stepping self-propelled tail to the left or right simultaneously. After the first slider 12 adjusts the stepping self-propelled tail to the desired position, the drive end of the drive mechanism 3 locks. The lifting mechanism 2 retracts, and the lifted end of the entire stepping self-propelled tail descends until it contacts the ground. Please refer to [reference needed]. Figure 9 This illustrates the range within which the nose guide rail 7 can be adjusted. When the nose guide rail 7 is adjusted, the forward direction of the stepping self-propelled tail changes accordingly with the offset direction of the nose guide rail 7.

[0058] In summary, the self-propelled walking machine tail-adjustment device provided by this invention utilizes a cooperating lifting mechanism and support rail during adjustment. The lifting mechanism raises the end of the self-propelled walking machine tail, and the support rail, via its upper guide rail, allows the raised end of the self-propelled walking machine tail to slide relative to the ground. During adjustment, the drive mechanism moves the first slider of the guide rail, which in turn moves the entire lifting mechanism. The lifting mechanism simultaneously causes the raised end of the self-propelled walking machine tail to slide, adjusting the direction of the tail-end and ultimately completing the adjustment. This invention allows for rapid adjustment of the offset direction of the self-propelled walking machine tail, reducing manpower input, saving construction costs, and ensuring personnel safety.

[0059] Please refer to Figure 1 , Figure 2 , Figure 7 and Figure 8 The present invention also discloses a stepping self-moving tail, wherein the end of the stepping self-moving tail is connected to the aforementioned stepping self-moving tail adjustment device, and the adjustment direction of the stepping self-moving tail adjustment device intersects with the moving direction of the stepping self-moving tail. The beneficial effects of the stepping self-moving tail disclosed in this invention are the same as the beneficial effects of the stepping self-moving tail adjustment device described in the above technical solution, and will not be repeated here.

[0060] For further details, please refer to... Figure 1 , Figure 2 and Figure 7 Another embodiment of the self-propelled stepping tail section of the present invention includes a traction unit 4, which serves as the traveling head of the entire self-propelled stepping tail section, driving the entire self-propelled stepping tail section forward. The traction unit 4 includes a traction unit frame 41, a first traveling lifting device 5, a telescopic pushing device 6, and a head control rail 7. The traction unit frame 41 is a supporting component, and the first traveling lifting device 5 lifts one end of the traction unit 4 by lifting the traction unit frame 41. Generally, there are two first traveling lifting devices 5, distributed on both sides of the traction unit 4.

[0061] Two main guide rails 7 are respectively installed on both sides of the traction unit frame 41. A first traveling lifting device 5 is installed between the traction unit frame 41 and each main guide rail 7. The body of the first traveling lifting device 5 is connected to the traction unit frame 41, and the lifting end of the first traveling lifting device 5 is fixedly connected to the second slider 71 of the main guide rail. A telescopic pushing device 6 is installed between the traction unit frame 41 and the main guide rail 7. The telescopic pushing device 6 extends in the same direction as the guiding direction of the main guide rail 7. One end of the telescopic pushing device 6 is connected to the traction unit frame 41, and the other end is connected to the main guide rail 7. The telescopic pushing device 6 is hinged to both the traction unit frame 41 and the main guide rail 7. In actual use, the second slider 71 is typically a pulley block with hooks at the bottom. The bottom of the traction unit frame 41 has a grounding support pillow 411, and the traction unit frame 41 is stably connected to the ground through the grounding support pillow 411.

[0062] For ease of understanding, the initial state of the working process is described as follows: the traction unit frame 41 is suspended in the air, and the main guide rail 7 supports the weight of the entire traction unit frame 41. The first traveling lifting device 5 retracts, the grounding support pillow 411 is grounded, and the traction unit frame 41 is supported on the ground by the grounding support pillow 411. Then, the first traveling lifting device 5 lifts the main guide rail 7 away from the ground, and the traction unit frame 41 supports the weight of the entire traction unit 4. Next, the telescopic pushing device 6 retracts, moving the main guide rail 7 forward. After the main guide rail 7 has moved forward, the first traveling lifting device 5 extends, bringing the main guide rail 7 closer to the ground. When the main guide rail 7 contacts the ground, the first traveling lifting device 5 continues to extend, lifting the entire traction unit frame 41, leaving the traction unit frame 41 suspended above the ground. During this process, the traction unit 4 completes one step-like traveling cycle.

[0063] Furthermore, such as Figure 1As shown, in another embodiment of the self-propelled tail section of the present invention, a first traveling lifting device 5 located at one end of the self-propelled tail section adjustment device is fixedly installed on both sides of the self-propelled tail section adjustment device. The first traveling lifting device 5 located at one end of the self-propelled tail section adjustment device is connected to the traction frame 41 through the connecting frame 23 of the self-propelled tail section adjustment device. In the above embodiment, after fixing the first traveling lifting device 5 to both sides of the connecting frame 23, the traction frame 41 is freed up with the connection position required for installing the first traveling lifting device 5, so the installation position of the telescopic pushing device 6 can be closer to the end of the traction frame 41. When the length of the main guide rail 7 of the machine head is constant, the closer the installation position of the telescopic pushing device 6 is to the end of the traction frame 41, the longer the maximum extension distance of the telescopic pushing device 6. The reason is as follows, Figure 2 As shown, lifting mechanisms 2 are provided on both the front and rear sides of the traction unit 4. During the extension of the telescopic pushing device 6, the hinge end of the telescopic pushing device 6 and the main guide rail 7 of the machine head may collide with the lifting mechanism 2 on the rear side of the traction unit 4. Therefore, the maximum extension distance of the telescopic pushing device 6 is limited between the lifting mechanisms 2 on the front and rear sides of the traction unit 4. As a result, the connection position required for installing the first traveling lifting device 5 is freed up on the traction unit frame 41, allowing the telescopic pushing device 6 to be installed further forward on the traction unit frame 41, and increasing the maximum extension distance of the telescopic pushing device 6.

[0064] For further details, please refer to... Figure 2 and Figure 7 In another embodiment of the self-propelled tail section of the present invention, the traction unit 4 further includes a motor oil pump group 8, which is mounted on the frame 41 of the traction unit. The first walking lifting device 5 and the telescopic pushing device 6 are both driven by hydraulic oil pumps. The power output end of the motor oil pump group 8 is connected to the power input end of the first walking lifting device 5 and the power input end of the telescopic pushing device 6, respectively.

[0065] In existing technology, the motor-driven oil pump assembly 8 is generally set in... Figure 7 The location of the storage section would make the connecting pipeline very long, which would not only make the wiring troublesome, but also affect the power output of the motor oil pump assembly 8. The present invention sets the motor oil pump assembly 8 and the oil tank assembly 83 in the traction section 4, which reduces the length of the connecting pipeline, simplifies the wiring of the connecting pipeline, and reduces the impact of the long connecting pipeline on the power output of the motor oil pump assembly 8.

[0066] For further details, please refer to... Figure 7 as well as Figure 10In another embodiment of the self-propelled stepping tail of the present invention, the self-propelled stepping tail further includes a rigid transport section connected to the rear end of the traction section 4. The rigid transport section includes a first transport frame 91, a second walking lifting device 92, and a first support guide rail 93. The first transport frame 91 is hinged to the traction section frame 41, and the main guide rail 7 of the head is hinged to the first support guide rail 93 in a horizontal direction. At least one second walking lifting device 92 is provided on each side of the first transport frame 91. The body of the second walking lifting device 92 is fixedly connected to the first transport frame 91, and the lifting end of the second walking lifting device 92 is connected to the third slider of the first support guide rail 93.

[0067] In the above embodiment, the rigid transport section is connected to the rear end of the traction section 4. The rigid transport section is provided with a sliding belt conveyor redirecting roller tensioning device 9, which is used for the belt to slowly change angle. The belt inclination angle transitions from 30 degrees to 20 degrees, then to 15 degrees, and then wraps around the redirecting roller, thus achieving the function of belt transition.

[0068] Please refer to Figures 10 to 13 The diagram illustrates the overall structure of the sliding belt conveyor redirecting roller tensioning device 9, which includes a redirecting roller 911, a first guide rail 912 and a second guide rail 914 symmetrically distributed on both sides of the redirecting roller 911, and a moving device.

[0069] The aforementioned redirecting roller 911 is closely connected to the belt 9111, and the entire belt 9111 forms a loop structure with its ends connected. The redirecting roller 911 is located on one side of the loop structure within the entire belt 9111. The redirecting roller 911 is a driven roller, meaning that when the belt 9111 is running, the redirecting roller 9111 rotates under the drive of the belt 9111. The redirecting roller 911 is located at the tail end of the machine.

[0070] The first guide rail 912 and the second guide rail 914 are symmetrically distributed on both sides of the redirecting roller 911. One end of the redirecting roller 911 is connected to the first slider 9121 of the first guide rail 912, and the other end is connected to the second slider 9141 of the second guide rail 914. Furthermore, the guiding directions of the first guide rail 912 and the second guide rail 914 are the same. Under the combined guidance of the first guide rail 912 and the second guide rail 914, the redirecting roller 911 can move stably back and forth. This ensures that the belt tension of the belt 9111 can be stably adjusted by adjusting the back and forth movement of the redirecting roller 91 during operation. Due to the improved stability of the redirecting roller 911 when adjusting its position, the problem of belt misalignment is reduced.

[0071] In one example, the first guide rail 912 is a first plate-shaped body with a first guide groove in the middle. The first track 9122 of the first guide rail 912 is the first guide groove, and the first slider 9121 is a first square sliding block that matches the shape of the first guide groove. The first square sliding block is located in the first guide groove and is slidably connected to the first guide groove. When adjusting the tension of the belt 9111, the requirements for the precision of the guiding device and the friction between the slider and the rail are relatively low. However, the requirements for the load-bearing capacity of the guide rail and the slider are relatively high. Therefore, the first guide rail 912 adopts a combination of a first plate-shaped body and a first square sliding block, simplifying its structure, eliminating the use of rollers, and making it robust and durable. Furthermore, there is a certain amount of friction between the first track 9122 and the first slider 9121 in the first guide groove. This friction can, to a certain extent, reduce the vibration of the redirecting roller 911, making the operation of the belt 9111 smoother.

[0072] First limiting blocks are connected to both sides of the first square sliding block. The diameter of the first limiting block is larger than the width of the first guide groove. The first limiting blocks are slidably connected to the surface of the first plate-shaped body. The first limiting blocks are used to prevent the first slider 9121 from deviating from the first track 9122, ensuring the smooth back-and-forth movement of the redirecting roller 911. In one feasible embodiment, the first limiting block and the first square sliding block are detachably connected. The advantage of the detachable connection is that when the first limiting block or the first square sliding block is worn significantly, it is easy to replace the first limiting block or the first square sliding block individually.

[0073] The second guide rail 914 is a second plate-shaped body with a second guide groove in the middle. The second track 9142 of the second guide rail 914 is the second guide groove. The second slider 9141 is a second square sliding block that matches the shape of the second guide groove. The second square sliding block is located in the second guide groove and is slidably connected to the second guide groove. When adjusting the tension of the belt 9111, the requirements for the accuracy of the guiding device and the friction between the slider and the rail are relatively low. However, the requirements for the load-bearing capacity of the guide rail and the slider are relatively high. Therefore, the second guide rail 914 adopts a combination of a second plate-shaped body and a second square sliding block, simplifying its structure, eliminating the use of rollers, and making it robust and durable. Furthermore, there is a certain friction between the second track 9142 and the second slider 9141 in the second guide groove. This friction can, to a certain extent, reduce the vibration of the redirecting roller 911, making the operation of the belt 9111 smoother.

[0074] The second square sliding block has second limiting blocks connected to both sides. The diameter of the second limiting blocks is larger than the width of the second guide groove, and the second limiting blocks are slidably connected to the surface of the second plate-shaped body. The second limiting blocks are used to prevent the second slider 9141 from deviating from the second track 9142, ensuring the smooth back-and-forth movement of the redirecting roller 911. In one feasible embodiment, the second limiting blocks and the second square sliding block are detachably connected. The advantage of this detachable connection is that when the second limiting block or the second square sliding block is worn significantly, it is easy to replace the second limiting block or the second square sliding block individually.

[0075] The drive end of the aforementioned drive device is connected to the first slider 9121 and / or the second slider 9141. The function of the drive device is to drive the redirecting roller 911 to move back and forth, and to increase the interaction force between the redirecting roller 911 and the belt 9111, so that the redirecting roller 911 can spread the belt 9111 and give the belt 9111 a tension force.

[0076] In one example, the drive unit includes a first drive section 913 and a second drive section 915 distributed on both sides of the redirecting roller 911. The first drive section 913 is drivenly connected to the first slider 9121, and the second drive section 915 is drivenly connected to the second slider 9141. The first drive section 913 or the second drive section 915 can be selected in various ways, such as a combination of a cylinder, a drive cylinder, a ball screw assembly, and a servo motor, or a combination of a linkage device capable of outputting linear power and a servo motor. By using the first drive section 913 and the second drive section 915 located on both sides of the redirecting roller 911, the forward and backward movement of the redirecting roller 911 can be adjusted through a dual-drive method. This effectively avoids direct contact between the first drive section 913 or the second drive section 915 and the redirecting roller 911, and also simplifies the installation method of the first drive section 913 and the second drive section 915, i.e., the first drive section 913 and the second drive section 915 are directly drivenly connected to the outermost first slider 9121 and the second slider 9141.

[0077] refer to Figures 10-13 During operation, the redirecting roller 911 runs together with the belt 9111. When the belt 9111 becomes slack, the working ends of the first drive unit 913 and the second drive unit 915 extend to the left simultaneously. The first slider 9121 moves to the left under the drive of the first drive unit 913, and the second slider 9141 moves to the left under the drive of the second drive unit 915. The redirecting roller 911, located between the first slider 9121 and the second slider 9141, moves to the left under the drive of the first slider 9121 and the second slider 9141. The redirecting roller 911 spreads the belt 9111, thus tensioning the belt 9111.

[0078] In summary, in the aforementioned sliding belt conveyor redirecting roller tensioning device 9, the redirecting roller can move stably back and forth via the first and second guide rails, allowing for stable adjustment of belt tension without stopping the machine. When adjusting the redirecting roller, the use of the first and second guide rails allows the drive end of the drive device to directly act on the first and second sliders, simplifying the overall connection structure of the invention. The overall structure of this invention is simple, stable, and highly reliable.

[0079] Optional, please refer to Figure 10 and Figure 11 In another embodiment of the sliding belt conveyor redirecting roller tensioning device 9, the sliding belt conveyor redirecting roller tensioning device 9 further includes a first transport frame 91, the first transport frame 91 having a receiving cavity in the middle, and the redirecting roller 911 located in the receiving cavity;

[0080] The first guide slide rail 912 and the second guide slide rail 914 are detachably and fixedly connected to the first transport frame 91, and the first guide slide rail 912 and the second guide slide rail 914 are located on the outer side of the first transport frame 91 on both sides of the receiving cavity.

[0081] The first transport frame 91 has a first through hole 9112, the minimum diameter of which is greater than the maximum diameter of the redirecting roller 911. The first through hole 9112 is located between the first guide rail 912 and the receiving cavity; and / or

[0082] The first transport frame 91 has a second through hole, the minimum diameter of which is greater than the maximum diameter of the redirecting roller 911. The second through hole is located between the second guide rail 914 and the receiving cavity.

[0083] One end of the first drive unit 913 is hinged to the first transport frame 91, and the other end of the first drive unit 913 is hinged to the first slider 9121.

[0084] One end of the second drive unit 915 is hinged to the first transport frame 91, and the other end of the second drive unit 915 is hinged to the second slider 9141.

[0085] In the above embodiment, to facilitate the replacement of the redirecting roller 911, the redirecting roller 911 is installed inside a first transport frame 91 with a receiving cavity in the middle. Furthermore, a first through hole 9112 is provided on one side of the first transport frame 91, allowing the redirecting roller 911 to be inserted laterally through the first through hole 9112 and installed into the receiving cavity within the first transport frame 91 when installing or removing and replacing the redirecting roller 911. Figure 1As shown, when disassembling and replacing the redirecting roller 911, firstly, the second drive unit 915 and the first guide rail 912 are removed, at which point there is no obstruction outside the first through hole 9112. Then, one end of the redirecting roller 911 is inserted into the first through hole 9112, and then the redirecting roller 911 is pushed into the receiving cavity inside the first transport frame 91. Similarly, the second through hole on the first transport frame 91 operates on the same principle as the first through hole 9112, and will not be described in detail here. This embodiment simplifies the installation of the redirecting roller 911 and facilitates its replacement. The first drive unit 913 is hinged to the first slider 9121 via the first connecting seat 916. The use of the first connecting seat 916 increases the length of the end of the first slider 9121, allowing the first drive unit 913 to be relatively far away from the first slider 9121, thus preventing the first drive unit 913 from colliding with other equipment during operation.

[0086] The second drive unit 915 is hinged to the second slider 9141 via the second connecting seat 917. The use of the second connecting seat 917 increases the length of the end of the second slider 9141, which allows the second drive unit 915 to be relatively far away from the second slider 9141, thus preventing the second drive unit 915 from colliding with other devices during operation.

[0087] For further details, please refer to... Figure 14 The rigid transport section also includes a sliding trolley 94 and a sliding trolley guide rail. The sliding trolley guide rail is fixed on the rigid transition transport frame, and the sliding trolley 94 is slidably connected to the rigid transition transport frame through the sliding trolley guide rail.

[0088] The sliding trolley 94 is provided with a rotary support assembly 941 for supporting the previous stage conveying device. The rotary support assembly 941 is hinged to the sliding trolley 94, and the forward and backward rotation direction of the rotary support assembly 941 is the same as the sliding direction of the sliding trolley 94.

[0089] Furthermore, the self-propelled tail section also includes a storage section 10 connected to the rear end of the rigid transport section. The storage section 10 includes a second transport frame 101, a third traveling lifting device 102, and a second support rail 103. The second transport frame 101 is hinged to the first transport frame 91, and the second support rail 103 is hinged to the first support rail 93 in a horizontal direction. At least one third traveling lifting device 102 is provided on each side of the second transport frame 101. The body of the third traveling lifting device 102 is fixedly connected to the second transport frame 101, and the lifting end of the third traveling lifting device 102 is connected to the fourth slider of the second support rail 103. The storage section 10 is used for material stacking, with the material moving forward with the assembly, saving workers from frequent material handling, saving time, and reducing labor intensity. In actual use, the third and fourth sliders are typically pulley blocks, with hooks at the bottom of the pulley blocks.

[0090] This invention also discloses a method for adjusting the tail of a stepping self-moving machine, comprising:

[0091] The end of the self-propelled stepping tail is lifted by a lifting mechanism, and the body of the lifting mechanism is fixedly installed with the body of the self-propelled stepping tail.

[0092] A support rail is installed at one end of the lifting mechanism so that the lifting mechanism can slide relative to the ground;
