Description
Technical Field
[0001] This invention relates to the field of conveyor technology, specifically to a tail self-moving device for a mining belt conveyor. Background Technology
[0002] In underground mining operations such as coal and metal mines, belt conveyors serve as core material conveying equipment. Their tail section must move synchronously with the advancement of the mining face to ensure the continuity of the conveying system. To achieve autonomous tail movement, the industry has widely adopted self-moving tail structures such as stepping and crawler types. Among these, the crawler-type self-moving tail has become one of the mainstream choices in mines with soft geological conditions due to its relatively large ground contact area and superior terrain adaptability compared to the traditional stepping structure.
[0003] However, in actual use, we have found that the geological conditions of underground mine tunnels are complex and varied, especially in areas of close-range coal seam mining, water-rich rock strata, or goaf. The tunnel floor often exhibits typical soft characteristics, specifically low bearing capacity and high water content in the floor rock strata. It is also prone to local depressions due to equipment rolling, accompanied by irregular protrusions, such as incompletely broken rock blocks and hardened coal seams. This soft geological environment poses a severe challenge to the adaptability of existing tracked self-moving tail sections. Therefore, we propose a tail self-moving device for mine belt conveyors. Summary of the Invention

Two expansion plates are disposed above the support plate, and the two expansion plates are respectively disposed at both ends of the bidirectional screw and threadedly connected to the bidirectional screw. A limit rod is provided on the support plate, and the limit rod passes through the two expansion plates. Both expansion plates are slidably disposed outside the limit rod.

[0015] In some embodiments, the steering assembly includes a rotating member disposed within the tail section, which drives a set of adjacent first and second rollers to rotate, thereby causing a set of adjacent first and second track plates to deflect in direction. A synchronizing member is disposed below the tail section, which drives a set of adjacent first and second rollers to move synchronously.

[0016] In some embodiments, the rotating component includes four rotating rods rotatably disposed within the tail body, each of the four rotating rods having a transmission plate in its middle section, each of the four transmission plates having a transmission groove at its opposite ends, and the four lifting hydraulic rods being respectively disposed at opposite ends of the four transmission plates.
[0017] In some embodiments, the synchronizing element includes two synchronizing plates disposed within the tail section of the machine body.

The second track plate slides with the first track plate, and with the help of blocks and baffles to fit the rollers, it can prevent the first and second track plates from slipping or getting stuck due to geological differences, thus ensuring basic mobility in complex environments.
[0021] 2. The dual-output shaft motor in the travel assembly provides ample power, and the lifting hydraulic rod allows for easy switching between start and stop states.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0034] Example 1: Please refer to Figure 1-10 The present invention provides a technical solution: a tail self-moving device for a mining belt conveyor, comprising a tail body 1, and further comprising:
[0035] Multiple first rollers 2 are provided, and the multiple first rollers 2 are located on one side of the tail body 1. Among the multiple first rollers 2, two adjacent ones form a group. Multiple second rollers 3 are provided on the side of the tail body 1 away from the multiple first rollers 2. Among the multiple second rollers 3, two adjacent ones form a group.
[0036] Multiple forward tracks 4 are provided, and all multiple forward tracks 4 are located on the outside of the first roller 2 and the second roller 3. The forward tracks 4 are used to switch different working modes to adapt to mine tunnels with different geological conditions.
[0037] The traveling component 5 is provided in multiple ways, and all of the traveling components 5 are located inside the tail body 1. The traveling components 5 drive the first roller 2 and the second roller 3 of the corresponding group to rotate, thereby driving the two first rollers 2 and the two second rollers 3 in each group to push the forward track 4, thus driving the tail body 1 to move in the complex mine tunnel through the multiple forward tracks 4.
[0038] There are multiple steering components 6, and all of them are located inside the tail body 1. By using the steering components 6 to synchronously adjust the direction of the first roller 2 and the second roller 3 of the corresponding group, the corresponding forward track 4 is driven to turn, thereby switching the movement direction of the tail body 1.
[0039] The forward track 4 includes two connecting rods 41 disposed within the tail body 1. Two connecting plates 42 are provided at both ends of the two connecting rods 41. Sliding grooves 43 are provided on opposite sides of the two connecting plates 42. Multiple sliding rods 44 are slidably and rotatably disposed within each sliding groove 43. First track plates 45 are provided on opposite ends of the multiple sliding rods 44. Guide grooves 46 are provided within each of the multiple first track plates 45. Second track plates 47 are slidably disposed within each of the multiple guide grooves 46. The multiple second track plates 47 are arranged in a surrounding manner around the outside of each group of first rollers 2 and second rollers 3. First pins 48 are provided on one side of each of the multiple first track plates 45. The multiple first track plates 45 are rotatably connected via adjacent first pins 48. The multiple second track plates... Each of the 47 tracks has a second pin 49 on one side. Multiple second track plates 47 are rotatably connected via adjacent second pins 49. On opposite sides of each of the multiple second track plates 47 are stops 410 that cooperate with each set of first rollers 2 and each set of second rollers 3. On opposite sides of each of the multiple second track plates 47 are baffles 411 that cooperate with each set of first rollers 2 and each set of second rollers 3. All baffles 411 are located on the opposite sides of the multiple first rollers 2 and second rollers 3. When the first rollers 2 and second rollers 3 rotate synchronously, they move along the stops 410 on the second track plates 47, thereby pushing the first track plates 45 and second track plates 47 forward synchronously. The baffle 411 effectively prevents the first roller 2 and the second roller 3 from shifting laterally during operation, ensuring stability and accuracy of movement. When the first track plates 45 on both sides of the tail body 1 move together with the second track plates 47, the sliding rod 44 on one side of the first track plate 45 slides in the sliding groove 43 opened on the connecting plate 42. The cooperation between the sliding rod 44 and the sliding groove 43 effectively limits the distance between the first track plate 45 and the tail body 1 to remain constant during movement, ensuring that the first track plate 45 maintains a stable relative position with the tail body 1 during movement, avoiding structural interference or power transmission failure caused by displacement deviation. The connecting plate 42 is fixed to the support plate 71 by the connecting rod 41, facilitating... Subsequently, when the first track plate 45 and the second track plate 47 are adjusted in direction, and the first roller 2 and the second roller 3 slide on the outside of the clamping plate 75 and the drive rod 74 through the slot 76, the first roller 2 and the second roller 3 will each push the corresponding baffle 411 and stop block 410 to move outward together. In turn, the baffle 411 and the stop block 410 will push the second track plate 47 to expand outward, so that the second track plate 47 gradually moves away from the tail body 1. The pushed second track plate 47 will slide on the first track plate 45 through the guide groove 46. Since the end of the first track plate 45 away from the second track plate 47 slides in the sliding groove 43 of the connecting plate 42 through the sliding rod 44, the outward expansion movement of the second track plate 47 will not drive the first track plate 45.This increases the distance between the second track plate 47 and the first track plate 45, thereby increasing the ground contact area between them. This effectively improves the load-bearing capacity and stability of the tail section 1 on soft ground, preventing sinking or slippage. The interceptor plate 77, located at one end of the drive rod 74, effectively prevents the first roller 2 and the second roller 3 from detaching from the drive rod 74 during expansion. Its function is to ensure that the first roller 2 and the second roller 3 are always confined within their effective working range when sliding and expanding along the drive rod 74, preventing structural instability or derailment due to excessive outward movement.
[0040] The traveling component 5 includes a drive unit 7 installed inside the tail body 1, which generates the power required for the movement of the tail body 1. A lifting component 8 is installed inside the tail body 1, which switches the traveling and stopping states of the tail body 1. An expansion component 9 is installed inside the tail body 1, which drives multiple second track plates 47 to slide outside the corresponding first track plates 45, thereby changing the contact area of the multiple first track plates 45 with the ground in conjunction with the multiple second track plates 47.
[0041] The drive unit 7 includes a support plate 71 disposed within the tail section 1, two connecting rods 41 respectively disposed at both ends of the support plate 71, a dual-output shaft motor 72 disposed at both ends of the support plate 71, a drive shaft 73 disposed at the center of each of the two dual-output shaft motors 72, a drive rod 74 disposed at both ends of each of the two drive shafts 73, multiple retaining plates 75 disposed on the outer sides of each of the four drive rods 74, and slots 76 for cooperating with the multiple retaining plates 75 being opened in the two first rollers 2 and the two second rollers 3. The two first rollers 2 and the two second rollers 3 slide on the outer sides of the corresponding retaining plates 75 and drive rods 74 through the multiple slots 76. An intercepting plate 77 is disposed at the end of each of the four drive rods 74 away from the two dual-output shaft motors 72. When the two dual-output shaft motors 72 are started simultaneously, the two... The dual-output shaft motor 72 drives the corresponding drive shaft 73 to rotate. When the drive shaft 73 rotates, the drive rods 74 at both ends of the drive shaft 73 will rotate together with the drive shaft 73. The multiple clamping plates 75 on the outside of the drive rods 74 will rotate with the rotation of the drive rods 74. At this time, the rotating clamping plates 75 will drive the first roller 2 and the second roller 3 to rotate synchronously through the corresponding clamping slots 76. Its function is to enable the first roller 2 and the second roller 3 to rotate synchronously under the drive of the clamping plates 75, thereby driving the first track plate 45 and the second track plate 47 to work together, ensuring the stability and efficiency of power transmission during movement. At the same time, the cooperation of the stop block 410 and the baffle plate 411 restricts the axial displacement of the rollers, improving the reliability of the structure operation.
[0042] The lifting component 8 includes four lifting hydraulic rods 81 located below the tail body 1. Each of the four lifting hydraulic rods 81 has a lifting block 82 rotatably mounted at its bottom end. The two ends of two drive shafts 73 pass through and are rotatably mounted in the corresponding lifting blocks 82. When the four lifting hydraulic rods 81 are activated, they extend and push the lifting blocks 82 at their bottom ends downward. When the four lifting blocks 82 descend simultaneously, the two drive shafts 73 rotatably mounted in the four lifting blocks 82 will also move downward together, so that the first track plate 45 and the second track plate 47 located below gradually contact the ground until the tail body 1 is completely lifted off the ground. Its function is to achieve stable switching between the traveling and working states of the tail body 1 through the coordinated operation of the lifting component 8, ensuring that the equipment has good adaptability and support in complex terrain.
[0043] The expansion component 9 includes an expansion motor 91 mounted on a support plate 71. A first bevel gear 92 is mounted at the output end of the expansion motor 91. A second bevel gear 93 meshes with the first bevel gear 92 below it. A bidirectional screw 94 is mounted at the shaft of the second bevel gear 93. Two expansion plates 95 are mounted above the support plate 71, respectively positioned at both ends of the bidirectional screw 94 and threadedly connected to it. A limit rod 96 is mounted on the support plate 71, passing through both expansion plates 95. Both expansion plates 95 are slidably mounted on the outside of the limiting rod 96. Bearings 97 are mounted at both ends of the two expansion plates 95, and the four bearings 97 are respectively positioned on opposite sides of the two first rollers 2 and the two second rollers 3. When the expansion motor 91 is started, it drives the first bevel gear 92 at its output end to rotate. The second bevel gear 93 meshing with it also rotates along with the first bevel gear 92. At this time, the second bevel gear 93 drives the bidirectional screw 94 located at its shaft to rotate. When the bidirectional screw 94 rotates, it... The two expansion plates 95 connected by four threads will move towards their opposite sides. The limiting rod 96 set on the support plate 71 can effectively limit the movement trajectory of the expansion plates 95, ensuring that they expand smoothly outward in a straight direction and avoiding skewed operation. As the two expansion plates 95 continue to expand outward, their ends away from the expansion motor 91 will push the corresponding bearings 97, causing the four bearings 97 to gradually move away from the support plate 71. At the same time, the first roller 2 and the second roller 3 set in the inner ring of the four bearings 97 will be pushed away from the support plate 71, making... The first roller 2 and the second roller 3 slide on the outside of the clamping plate 75 and the drive rod 74 through the groove 76 at their respective shaft centers. Their function is to realize the synchronous outward movement of the first roller 2 and the second roller 3 through the transmission linkage of the expansion member 9, effectively adjusting the distance between the first track plate 45 and the second track plate 47, thereby effectively increasing the contact area between the first track plate 45 and the second track plate 47 and the ground, enhancing the grip and stability of the equipment in soft or muddy mine tunnels, and thus improving the passability and operational safety of the whole machine under harsh working conditions.
[0044] The steering assembly 6 includes a rotating component 10 disposed within the tail body 1. The rotating component 10 drives a set of first rollers 2 and second rollers 3 adjacent to it to rotate, thereby causing a set of first track plates 45 and second track plates 47 adjacent to it to deflect in direction. A synchronizing component 11 is disposed below the tail body 1. The synchronizing component 11 drives a set of first rollers 2 and second rollers 3 adjacent to it to move synchronously. A limiting component 12 is disposed below the tail body 1. The limiting component 12, in conjunction with the synchronizing component 11, drives a set of first rollers 2 and second rollers 3 adjacent to it to remain stable during the steering process.
[0045] The rotating component 10 includes four rotating rods 101 rotatably disposed within the tail body 1. Each of the four rotating rods 101 has a transmission plate 102 in its middle section. Each of the four transmission plates 102 has a transmission groove 103 at its opposite ends. Four lifting hydraulic rods 81 are respectively disposed at the opposite ends of the four transmission plates 102. The moving synchronizing rods 112 push the transmission plates 102 through the corresponding transmission grooves 103, causing the transmission plates 102 located on opposite sides of the two synchronizing plates 111 to rotate on the tail body 1 via the rotating rods 101. Inside, and the rotation angles of the two transmission plates 102 are the same, when the transmission plate 102 rotates through the rotating rod 101 in its middle section, the end of the transmission plate 102 away from the transmission groove 103 will also deflect at an angle. When the end of the transmission plate 102 away from the transmission groove 103 deflects, the lifting hydraulic rod 81 set at the opposite end of the transmission plate 102 will change angle along with it. When the two opposing transmission plates 102 rotate, their opposite ends will form a relative angle change with the tail body 1, thereby driving The distance between the lifting hydraulic rod 81 and the tail body 1 changes. At this time, the lifting block 82, which is rotatably set at the bottom of the lifting hydraulic rod 81, will rotate due to the action of the drive shaft 73, thus ensuring that the drive shaft 73 and the lifting block 82 are on the same axis. This causes the drive shaft 73 to cross the tail body 1. When both drive shafts 73 cross the tail body 1 at the same time, and the two drive shafts 73 are relatively parallel, the relative parallel relationship between the drive shafts 73 makes the first roller 2 and the second roller 3 on both sides move in the same direction. This ensures that when the first roller 2 and the second roller 3 move through the first track plate 45 and the second track plate 47, the tail body 1 can maintain its original posture while moving diagonally forward or diagonally backward, achieving precise directional adjustment. Its function is to adjust the direction of the first roller 2 and the second roller 3 by changing the relative angle between the drive shaft 73 and the tail body 1, thereby achieving overall steering control of the tail body 1.
[0046] The synchronizing component 11 includes two synchronizing plates 111 disposed within the tail body 1. Each end of the two synchronizing plates 111 has a synchronizing rod 112 at its top. Four synchronizing rods 112 are slidably disposed within corresponding transmission grooves 103. A synchronizing gear 113 is rotatably disposed within the tail body 1 via a rotating shaft, and the synchronizing gear 113 is located between the two synchronizing plates 111. Multiple toothed grooves 114 are formed on opposite sides of the two synchronizing plates 111 to engage with the synchronizing gear 113. An electric push rod 115 is disposed within the tail body 1. The output end of the electric push rod 115 is disposed at one end of one of the two synchronizing plates 111. The electric push rod 115 pushes one of the synchronizing plates 111 at its output end, causing the output synchronizing plate 111 to drive a connected limiting plate 123 to slide within a limiting groove 122. The limiting groove 122 formed within the fixing plate 121, in conjunction with the limiting plate 123, controls the movement trajectory of the synchronizing plate 111. The guide and limit mechanism ensures stable and unbiased translation. When the synchronous plate 111 at the output end of the electric actuator 115 moves, the toothed groove 114 on one side pushes the synchronous gear 113 meshing with it to rotate. When the synchronous gear 113 rotates, it drives the two synchronous plates 111 to move synchronously in opposite directions through the toothed groove 114. When the two synchronous plates 111 move synchronously in opposite directions, the synchronous plates 111 at both ends of the two synchronous plates 111 will move together with the corresponding synchronous plates 111. Its function is to make the two sets of synchronous rods 112 slide synchronously in opposite directions in the transmission groove 103, thereby driving the four transmission plates 102 together with the rotating rods 101 connected to them to move in coordination. This ensures that the two drive shafts 73 swing synchronously while their swing angle is precisely controlled, so that the first roller 2 and the second roller 3 have the same turning angle, ensuring that the tail body 1 maintains a stable posture during the movement after changing direction.
[0047] The limiting component 12 includes two fixed plates 121 disposed inside the tail body 1. Each fixed plate 121 has a limiting groove 122. Each of the two synchronizing plates 111 has a limiting plate 123 on its top that works in conjunction with the two limiting grooves 122. The limiting grooves 122 disposed inside the fixed plates 121 can work with the limiting plates 123 to guide and limit the movement trajectory of the synchronizing plates 111, ensuring that its translation process is stable and without deviation. Its function is to limit the movement trajectory of the two synchronizing plates 111, ensuring that the tooth grooves 114 on their opposite sides do not disengage from the meshing state with the synchronizing gears 113.
[0048] When the operator needs to move the tail section 1 within the mine tunnel, initially, the first track plate 45 and the second track plate 47 are not in contact with the ground, while the bottom of the tail section 1 is in contact with the ground. At this time, the four lifting hydraulic rods 81 are simultaneously activated, extending them and pushing the lifting blocks 82 at their bottom ends downwards. As the four lifting blocks 82 descend simultaneously, the two drive shafts 73, which are rotatably installed within the four lifting blocks 82, will also move downwards together, causing the first track plate 45 and the second track plate 47 located below to gradually contact the ground until the tail section... The main body 1 is completely lifted off the ground. At this point, the four lifting hydraulic rods 81 stop operating, and then two dual-output shaft motors 72 are simultaneously activated. The two dual-output shaft motors 72 will drive the corresponding drive shafts 73 to rotate. When the drive shafts 73 rotate, the drive rods 74 located at both ends of the drive shafts 73 will rotate along with the drive shafts 73. The multiple locking plates 75 located on the outside of the drive rods 74 will rotate with the rotation of the drive rods 74. At this time, the rotating locking plates 75 will drive the first roller 2 and the second roller 3 through the corresponding locking slots 76. When the first roller 2 and the second roller 3 rotate synchronously, they move along the stop 410 on the second track plate 47, thereby pushing the first track plate 45 and the second track plate 47 forward synchronously. The stop 411 on the second track plate 47 can effectively prevent the first roller 2 and the second roller 3 from shifting laterally during operation, ensuring the stability and accuracy of movement. When the first track plates 45 on both sides of the tail body 1 move together with the second track plates 47, the stop 410 on the first track plate 45... The sliding rod 44 on one side slides in the sliding groove 43 opened on the connecting plate 42. The cooperation between the sliding rod 44 and the sliding groove 43 can effectively limit the distance between the first track plate 45 and the tail body 1 during the movement, ensuring that the first track plate 45 always maintains a stable relative position with the tail body 1 during the movement, avoiding structural interference or power transmission failure caused by displacement deviation. The connecting plate 42 is fixed on the support plate 71 by the connecting rod 41, which facilitates the subsequent directional adjustment of the first track plate 45 and the second track plate 47.
[0049] When the tail section 1 encounters relatively soft ground during travel, the lifting hydraulic rod 81 is first retracted, allowing the tail section 1 to re-establish contact with the ground for subsequent adjustments. After the first track plate 45 and the second track plate 47 are completely off the ground and the bottom of the tail section 1 is in full contact with the ground, the expansion motor 91 is activated. At this time, the expansion motor 91 will drive the first bevel gear 92 at its output end to rotate, and the second bevel gear 93 meshing with it will also rotate along with the first bevel gear 92. At this time, the second bevel gear 93 will drive the bidirectional screw 94 located at its shaft to rotate. When the screw 94 rotates, the two expansion plates 95, which are threadedly connected to the bidirectional screw 94, will move toward their opposite sides. The limiting rod 96 set on the support plate 71 can effectively limit the movement trajectory of the expansion plates 95, ensuring that they expand smoothly outward in a straight direction and avoiding skewed operation. As the two expansion plates 95 continue to expand outward, their ends away from the expansion motor 91 will push the corresponding bearings 97, causing the four bearings 97 to gradually move away from the support plate 71. At the same time, the first roller 2 and the second roller 3, which are respectively set in the inner ring of the four bearings 97, will be pushed away from the support plate 71, so that the first roller 2 and the second roller 3 are respectively pushed away from the support plate 71. The second roller 3 slides on the outside of the clamping plate 75 and the drive rod 74 through the slots 76 at their respective axes. When the first roller 2 and the second roller 3 slide on the outside of the clamping plate 75 and the drive rod 74 through the slots 76, the first roller 2 and the second roller 3 will each push the corresponding baffle 411 and stop block 410 to move outward together. Then, the baffle 411 and the stop block 410 will push the second track plate 47 to expand outward, so that the second track plate 47 gradually moves away from the tail body 1. The pushed second track plate 47 will slide on the first track plate 45 through the guide groove 46. The end of 45 away from the second track plate 47 slides in the sliding groove 43 of the connecting plate 42 through the sliding rod 44. Therefore, the outward expansion movement of the second track plate 47 will not drive the first track plate 45, thereby increasing the distance between the second track plate 47 and the first track plate 45, and thus increasing the ground contact area between the first track plate 45 and the second track plate 47. This effectively improves the load-bearing capacity and travel stability of the tail body 1 on soft ground, and avoids sinking or slipping. The intercepting plate 77 set at one end of the drive rod 74 can effectively prevent the first roller 2 and the second roller 3 from detaching from the drive rod 74 during the expansion process.
[0050] When the operator needs to adjust the forward direction of the tail section 1, it must be ensured that the first track plate 45 and the second track plate 47 are completely off the ground, and that the bottom of the tail section 1 remains in stable contact with the ground. Then, the electric actuator 115 is activated. The electric actuator 115 pushes a synchronization plate 111 at its output end, causing the synchronization plate 111 to slide the connected limiting plate 123 within the limiting groove 122. The limiting groove 122 within the fixed plate 121, in conjunction with the limiting plate 123, guides and limits the movement trajectory of the synchronization plate 111, ensuring stable and unbiased translation. When the synchronization plate 111 at the output end of the electric actuator 115 moves... When the tooth groove 114 on one side drives the synchronous gear 113 to rotate, the synchronous gear 113 will drive the two synchronous plates 111 to move synchronously in opposite directions through the tooth groove 114. When the two synchronous plates 111 move synchronously in opposite directions, the synchronous plates 111 located at both ends of the two synchronous plates 111 will move together with the corresponding synchronous plates 111. At this time, the moving synchronous rod 112 will push the transmission plate 102 through the corresponding transmission groove 103, so that the transmission plates 102 located on the opposite sides of the two synchronous plates 111 will rotate in the tail body 1 through the rotating rod 101, and the transmission plates on both sides The rotation angles of 102 are the same. When the transmission plate 102 rotates through the rotating rod 101 in its middle section, the end of the transmission plate 102 away from the transmission groove 103 will also deflect at an angle. When the end of the transmission plate 102 away from the transmission groove 103 deflects, the lifting hydraulic rod 81 set at the opposite end of the transmission plate 102 will also change angle along with it. When the two opposing transmission plates 102 rotate, their opposite ends will form a relative angle change with the tail body 1, thereby causing the distance between the lifting hydraulic rod 81 and the tail body 1 to change. At this time, the lifting block 82 set at the bottom of the lifting hydraulic rod 81 will be driven by the drive shaft 73. The drive shaft 73 rotates under the action of the lifting block 82, thereby ensuring that the drive shaft 73 can keep the same axis as the lifting block 82. This causes the drive shaft 73 to cross relative to the tail body 1. When the two drive shafts 73 cross relative to the tail body 1 at the same time, and the two drive shafts 73 are relatively parallel, the relative parallel relationship between the drive shafts 73 makes the first roller 2 and the second roller 3 on both sides obtain the same direction of movement. This ensures that when the first roller 2 and the second roller 3 move through the first track plate 45 and the second track plate 47, the tail body 1 can maintain its original posture while moving diagonally forward or diagonally backward, achieving precise directional adjustment.
