DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0021] Embodiment 1: Figures 1 to 9 As shown, a track laying machine for tunnel railway construction according to an embodiment of the present invention comprises: Mobile box 1; the mobile box 1 can move along the ground through rollers, and the rollers can be rotatably arranged; the mobile box 1 can be fixed on the vehicle and move with the vehicle; the mobile box 1 is provided with openings at the top and bottom; A cylinder 4, wherein the cylinder 4 is rotatably mounted in the middle of the mobile box 1 via a support shaft 7 that passes through the center; A conveying assembly, which is arranged on the top of the mobile box 1, and the sleepers are transported to the top of the cylinder 4 through the conveying assembly. The conveying assembly includes a conveyor belt 1 2 and a conveyor belt 2 3. The conveyor belt 1 2 and the conveyor belt 2 3 are adjacent and flush with the top ends. The conveyor belt 2 3 is provided with two and is aligned with the two sides of the conveyor belt 1 2 respectively; A laying assembly, which is arranged on the cylinder 4, through which the sleepers are taken off the conveying assembly and the sleepers are laid at a predetermined position; the laying assembly includes a movable rod 16, a clamping assembly for clamping the sleepers is provided at the top of the movable rod 16, a fixed block 29 is fixed at the bottom end of the movable rod 16, the fixed block 29 is sealingly slidably arranged in the movable cavity 15 provided on the cylinder 4, a permanent magnet 30 is fixed at the bottom of the fixed block 29, and an electromagnetic block 28 is inlaid at the corresponding position of the support shaft 7; A driving assembly, which is arranged inside the mobile box 1 and drives the cylinder 4 to rotate; During operation, the conveyor belt 1 2 and the conveyor belt 2 3 are driven to rotate by the driving motor respectively, and then the sleepers are placed on the conveyor belt 1 2, and the sleepers are transferred to the conveyor belt 2 3 by the conveyor belt 1 2. The rotation speed of the conveyor belt 1 2 is greater than that of the conveyor belt 2 3, and when the conveyor belt 2 3 transports the sleepers to the top of the cylinder 4, the movement is suspended, and the cylinder 4 is driven to rotate by the driving assembly, so that the laying assembly is rotated to the bottom of the sleepers. At this time, the permanent magnet 30 and the electromagnetic block 28 are opposite to each other. At this time, the electromagnetic block 28 is automatically energized by the controller to control the current direction of the electromagnetic block 28, so that the electromagnetic block 28 and the permanent magnet 30 repel each other, so that the fixed block 29, the movable rod 16 and the clamping assembly are pushed upward by the mutual repulsion, and the sleepers are first pushed upward by the clamping assembly to separate the sleepers from the conveyor belt 2 3, and then the sleepers are clamped, so that the sleepers can be taken smoothly and stably, without causing excessive impact on related equipment, thereby extending the service life of the device; then the cylinder 4 is driven to rotate by the driving assembly to bring the sleepers away from the range of the conveyor belt 2 3, At this time, the conveyor belt 1 2 and the conveyor belt 2 3 are started again to transport another sleeper. At the same time, when the sleeper leaves the range of the conveyor belt 2 3, the electromagnetic block 28 is powered off. At this time, under the action of gravity, the fixed block 29, the permanent magnet 30, the movable rod 16, the clamping assembly and the sleeper and other structures move relatively toward the inside of the active cavity 15, and the cylinder 4 is driven by the driving assembly to rotate 180 degrees, so that the sleeper rotates to a vertical downward position. At this time, the restriction of the clamping assembly on the sleeper is removed, so that the sleeper falls freely at the preset position to complete the laying work; when the sleeper moves to the oblique downward range with the cylinder 4, under the action of gravity, the clamping assembly and the related parts of the sleeper can slowly move outward along the active cavity 15, so that when the sleeper moves to the vertical position, the sleeper can be as close to the ground as possible, so that when the sleeper is released, the sleeper can quickly contact the ground, reducing the influence of the horizontal movement of the mobile box 1 on the landing point of the sleeper; in addition, at least one pair of laying assemblies and clamping assemblies are provided, which can cyclically clamp and release the sleepers to improve the laying efficiency.

[0022] The clamping assembly includes a support plate 17, which is horizontally fixed on the top of the movable rod 16, and a connecting block 22 is rotatably installed in the movable grooves opened at both ends of the support plate 17, and a clamping plate 18 is fixed on the top of the connecting block 22. A piston three 31 is provided with a sealing sliding sleeve in the middle of the movable rod 16, and a support rod 23 is fixed on the top of the piston three 31. A movable sleeve 20 is fixed on the top of the support rod 23, and the movable sleeve 20 is slidably sleeved on the movable rod 16, and oblique support plates 21 are symmetrically rotatably installed at both ends of the top of the movable sleeve 20, and the oblique support plates 21 are rotatably installed on the end of the extension plate at the bottom of the connecting block 22 away from the end of the movable sleeve 20. A sealing cover 8 is rotatably installed at the center of the end of the cylinder 4, and a connecting pipe 10 is fixed to the side wall of the sealing cover 8. A piston 24 is sealingly and slidably installed in the middle of the connecting pipe 10, and a hydraulic cylinder 9 for driving the piston 24 to reciprocate is fixed on the inner wall of the movable box 1, and an air passage 25 is provided inside the cylinder 4. The gas inside the sealing cover 8 can enter the cavity between the fixed block 29 and the piston three 31 through the air channel 25; during operation, when taking the sleeper, the piston one 24 is pushed toward the inside of the connecting pipe one 10 by the hydraulic cylinder 9, and the gas is squeezed into the sealing cover 8. At the same time, the gas enters the cavity between the fixed block 29 and the piston three 31 along the air channel 25. The gas in the cavity increases, and the piston three 31 is pushed away from the fixed block 29. The piston three 31 pushes the movable sleeve 20 through the support rod 23, and the movable sleeve 20 pushes the extension plate at the bottom of the connecting block 22 through the diagonal support plate 21, so that the two side clamps 18 rotate toward the middle with the connecting block 22 as the center and clamp the sleeper, so as to clamp and fix the sleeper; when the sleeper moves to the vertical position, the hydraulic cylinder 9 is controlled to contract, driving the piston one 24 to move in the opposite direction, and then the gas inside the cavity is extracted, so that the piston one 24 moves in the opposite direction, and then drives the clamp 18 to move in the opposite direction, so as to release the sleeper, which is convenient for automatic laying of the sleeper.

[0023] The driving assembly includes a transmission wheel 11, which is rotatably mounted on the mobile box 1 through a rotating shaft. A motor 6 for driving the rotating shaft and the transmission wheel is fixed on the outer wall of the mobile box 1. A transmission wheel 2 13 is fixed on the outer wall of the end of the cylinder 4. The transmission wheel 11 and the transmission wheel 2 13 are connected by a transmission chain 12, and the transmission chain 12 transmits torque between the transmission wheel 11 and the transmission wheel 2 13. When working, the transmission wheel 11 and the transmission wheel 2 13 can adopt sprocket wheels, and the transmission chain 12 can be a paired chain. The transmission wheel 11 is driven to rotate by the motor 6, and then the transmission wheel 2 13 and the cylinder 4 are driven to rotate by the transmission chain 12, providing driving force for the cylinder 4, so as to control the rotation and pause of the cylinder 4 as needed to meet the laying requirements; in addition, by controlling the rotation speed of the motor 6, the rotation speed of the cylinder 4 can be controlled, and then combined with the movement speed of the mobile box 1, the distance between two adjacent sleepers can be controlled as needed, which is suitable for different laying needs and has a wider range of use.

[0024] The invention also includes a correction component, which is used to correct the position of the sleepers so that the distances between adjacent sleepers are equal. The correction component includes a mounting cover 5 fixed to the middle of the cylinder 4, an inner cavity is provided on the inner side of the mounting cover 5, the air passage 25 is connected to the inner cavity, a connecting pipe 26 is fixed on the inner wall of the mounting cover 5, a piston 27 is sealingly and slidably installed inside the connecting pipe 26, a shift rod 14 is fixed on the side of the piston 27, the end of the shift rod 14 away from the piston 27 extends to the outside of the mounting cover 5, an air hole 33 is provided at the center of the end of the connecting pipe 26 away from the inner wall of the mounting cover 5, a flap 34 is hingedly connected to the inner end of the connecting pipe 26 and located at the outer side of the air hole 33 through a torsion spring, and an air hole 35 is provided on the side of the air hole 33; when working, when the inside of the device is inflated through the piston 24 and the connecting pipe 10, the gas simultaneously enters the inner cavity of the mounting cover 5 through the air passage 25, the air pressure inside the inner cavity increases, and the gas passes through the air passage 25. The air in the connecting pipe 26 can be discharged only through the air hole 35, and the air outlet rate is reduced, resulting in a slower retreat speed of the piston 27 and the lever 14, which has the effect of delaying the reset of the lever 14. In this way, during the rotation of the cylinder 4, the lever 14 can contact the sleeper on the ground, push the sleeper, and adjust the position of the sleeper so that the distance between two adjacent sleepers is the same; when the lever 14 is completely reset, it can pass over the sleeper to carry out the next laying work.

[0025] An anti-slip block is fixed on the inner wall of the active chamber 15 ; during operation, the anti-slip block can limit the movement range of the second piston 27 to prevent the second piston 27 from escaping from the active chamber 15 .

[0026] The diameter of the air hole 1 33 is greater than the diameter of the air hole 2 35 ; when working, it is used to reduce the rate at which gas is discharged from the connecting pipe 2 26 so as to delay the reset of the lever 14 .

[0027] A partition 32 is fixed inside the installation cover 5, and the inner cavity of the installation cover 5 is divided into two halves by the partition 32; when working, the laying component and the shifting component are each provided with two groups, and the inner cavity of the installation cover 5 is separated by the partition 32, so that they can be controlled separately by the hydraulic cylinders 9 at both ends without causing interference.

[0028] The clamping plate 18 is configured to be L-shaped; during operation, the clamping plate 18 can be used to clamp and fix both sides and the upper part of the sleeper, so that the sleeper will not fall off during the rotation of the cylinder 4.

[0029] Embodiment 2: Fig. 9 As shown, compared with Example 1, another implementation of the present invention is: a connecting plate 19 is fixed to the side wall of the support plate 17, and the adjacent clamping assemblies are connected together by the connecting plate 19; when working, the support plates 17 in the clamping assemblies on both sides are connected together by the connecting plate 19, so that the clamping assemblies on both sides can be limited, so that the clamping plates 18 on both sides maintain a parallel position, which is convenient for clamping and fixing the sleepers at the same time.

[0030] Working principle: Place the sleepers on conveyor belt 1 2, transfer the sleepers to conveyor belt 2 3 through conveyor belt 1 2, the rotation speed of conveyor belt 1 2 is greater than that of conveyor belt 2 3, and when conveyor belt 2 3 transports the sleepers to the top of cylinder 4, it stops moving, and at the same time drives cylinder 4 to rotate through the driving assembly, so that the laying assembly rotates to the bottom of the sleepers. At this time, the permanent magnet 30 and the electromagnetic block 28 are opposite to each other. At this time, the electromagnetic block 28 is automatically energized by the controller to control the current direction of the electromagnetic block 28, so that the electromagnetic block 28 and the permanent magnet 30 repel each other, so that the fixed block 29, the movable rod 16 and the clamping assembly are pushed upward by the mutual repulsion, and the sleepers are first pushed upward by the clamping assembly to separate the sleepers from conveyor belt 2 3, and then Then, the sleeper is clamped, so that the sleeper can be stably picked up; then, the cylinder 4 is driven to rotate by the driving component to bring the sleeper away from the range of the conveyor belt 2 3. At this time, the conveyor belt 1 2 and the conveyor belt 2 3 are started again to transport another sleeper. At the same time, when the sleeper leaves the range of the conveyor belt 2 3, the electromagnetic block 28 is powered off. At this time, under the action of gravity, the fixed block 29, the permanent magnet 30, the movable rod 16, the clamping component and the sleeper and other structures move relatively toward the inside of the movable cavity 15. The cylinder 4 is driven to rotate 180 degrees by the driving component, so that the sleeper rotates to a vertical downward position. At this time, the restriction of the clamping component on the sleeper is removed, so that the sleeper falls freely at the preset position to complete the laying work; when the sleeper moves to the oblique downward range with the cylinder 4, Under the action of gravity, the clamping assembly and the related parts of the sleeper can slowly move outward along the movable cavity 15, so that when the sleeper moves to the vertical position, the sleeper can be as close to the ground as possible, so that when the sleeper is released, the sleeper can quickly contact the ground, reducing the impact of the horizontal movement of the mobile box 1 on the landing point of the sleeper; when the inside of the device is inflated through the piston 1 24 and the connecting pipe 1 10, the gas simultaneously enters the inner cavity of the mounting cover 5 through the air channel 25, the air pressure inside the inner cavity increases, and the gas enters the connecting pipe 2 26 through the air hole 1 33 and the air hole 2 35. At this time, the flap 34 is opened to facilitate air intake, thereby pushing the piston 2 27 to move outward, and the piston 2 27 drives the lever 14 to move outward. When it reaches the vertical position, the restriction of the clamping assembly on the sleeper is removed by pumping air outwards, so that the sleeper can fall freely. At the same time, the gas inside the mounting cover 5 is also pumped out, so that the gas in the inner cavity of the connecting pipe 26 is pumped out synchronously. At this time, the flap 34 is closed, and the air hole 1 33 is blocked. The gas inside the connecting pipe 26 can only be discharged through the air hole 2 35, and the air output is reduced, resulting in a slower retreat speed of the piston 2 27 and the lever 14, which plays a role in delaying the reset of the lever 14. In this way, during the rotation of the cylinder 4, the lever 14 can contact the sleeper on the ground, push the sleeper, and adjust the position of the sleeper so that the distance between two adjacent sleepers is the same; when the lever 14 is fully reset, it can pass over the sleeper to carry out the next laying work.
