DETAILED DESCRIPTION

[0022] 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 described below in conjunction with specific implementation methods.

[0023] See also Figure 1 and Figure 2 The utility model provides a technical solution: a track transfer device, including a support frame 1, a plurality of first fixed seats 2 are fixedly connected to the top of the support frame 1, a first rotating rod 3 is rotatably connected inside the first fixed seat 2, a roller 4 is fixedly connected to the surface of the first rotating rod 3, a driving motor 5 is arranged below the support frame 1, a pulley 6 is fixedly connected to the output end of the driving motor 5 and the surface of the first rotating rod 3, a belt 7 is movably connected to the surface of the pulley 6, a detection component 8 is fixedly connected to the top of the support frame 1 between the two first fixed seats 2, an adjustment component 9 is fixedly connected to the inner wall of the support frame 1, a track transfer driving component 10 is fixedly connected to the top of the adjustment component 9, and a track storage platform 11 is arranged on one side of the support frame 1.

[0024] The driving motor 5, the pulley 6, the belt 7 and the first rotating rod 3 will drive several rollers 4 to rotate synchronously, so that the rails can be transported. The position detection baffle 82 and the torsion spring 83 in the detection assembly 8 can press the first switch 84. After a delay of several minutes, the roller 4 will stop rotating and the rail switching motor 103 will start, and the second rotating rod 102, the sprocket 104 and the chain 105 will drive the shifting block 106 to move. As the shifting block 106 continues to move, it will contact and push the rail to separate from the top of the roller 4 and separate from the roller. The rails at the top of the drum 4 will eventually fall to the top of the rail storage platform 11 for storage. As the chain 105 continues to run, the shift block 106 will press the second switch 85. The drum 4 will continue to rotate and the rail transfer drive assembly 10 will stop running, so that the rails can continue to be transported. The adjustment motor 92, the lead screw 91 and the guide rod 94 can be used to drive the adjustment seat 93 to move, thereby driving the shift block 106 in the rail transfer drive assembly 10 to move, so that the position of the shift block 106 can be adjusted according to the length of the rails, thereby expanding the scope of use of the device.

[0025] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The detection component 8 includes two second fixed seats 81 fixedly connected to the top of the support frame 1, a position detection baffle 82 is rotatably connected inside the second fixed seat 81, two torsion springs 83 are fixedly connected to one side of the position detection baffle 82, the torsion spring 83 and the second fixed seat 81 are fixedly connected, a first switch 84 is fixedly connected to the inner wall of the support frame 1 on one side of the position detection baffle 82 close to the torsion spring 83, and a second switch 85 is fixedly connected inside the adjustment component 9. When the front of the rail contacts the position detection baffle 82, the front of the rail will press down the position detection baffle 82 so that the position detection baffle 82 rotates around the second fixed seat 81 until the position detection baffle 82 presses the first switch 84. During this process, the torsion spring 83 will be deformed after being squeezed by the position detection baffle 82, and then the rail will continue to be transported forward. When the tail of the rail leaves the position detection baffle 82, the torsion spring 83 will recover and push the position detection baffle 82 back to its original position. After pressing the first switch 84, after a delay of several minutes, the roller 4 will stop rotating and the rail transfer drive assembly 10 will start, so that the rail can be pushed to the top of the rail storage platform 11. As the chain 105 continues to run, the shift block 106 will press the second switch 85. At this time, the roller 4 will continue to rotate and the rail transfer drive assembly 10 will stop running, so that the rail can continue to be transported.

[0026] The adjustment assembly 9 includes a lead screw 91 fixedly connected to the inner wall of the support frame 1, an adjustment motor 92 fixedly connected to one side of the lead screw 91, an adjustment seat 93 threadedly connected to the surface of the lead screw 91, a guide rod 94 slidably connected in the adjustment seat 93, and a fixed connection between the guide rod 94 and the inner wall of the support frame 1. Due to the difference in the length of different rails, the shift block 106 may not be able to smoothly make the rail detach from the top of the roller 4 when pushing the rail. At this time, the adjustment motor 92 can be started, and the adjustment motor 92 will drive the lead screw 91 to rotate, and the guide rod 94 will make the adjustment seat 93 move along the lead screw 91, thereby driving the shift block 106 in the rail switching drive assembly 10 to move, so that the position of the shift block 106 can be adjusted according to the length of the rail, expanding the scope of use of the device.

[0027] The rail-switching drive assembly 10 includes a plurality of third fixed seats 101 fixedly connected to the top of the adjustment assembly 9, a second rotating rod 102 is rotatably connected in the third fixed seat 101, a rail-switching motor 103 is fixedly connected to one end of the second rotating rod 102 extending out of the third fixed seat 101, a sprocket 104 is fixedly connected to the surface of the second rotating rod 102, a chain 105 is movably connected to the surface of the sprocket 104, and a shifting block 106 is fixedly connected to the outer side of the chain 105. After a delay of several minutes after pressing the first switch 84, the roller 4 will stop rotating and the rail-switching motor 103 will start, the rail-switching motor 103 will drive the second rotating rod 102 in the third fixed seat 101 to rotate, and then drive the sprocket 104 connected to the surface of the second rotating rod 102 to rotate and drive the chain 105 to run, as the chain 105 runs, the shifting block 106 connected to the outer side thereof will contact and push the rail to make it detach from the top of the roller 4, and the rail detached from the top of the roller 4 will eventually fall to the top of the rail storage platform 11 for storage.

[0028] The top surface of the drum 4 is higher than the top surface of the first fixed seat 2, and the top surface of the position detection baffle 82 is higher than the top surface of the drum 4. The top surface of the drum 4 is higher than the top surface of the first fixed seat 2 to ensure that the rail can be smoothly pulled away from the drum 4, and the top surface of the position detection baffle 82 is higher than the top surface of the drum 4 to ensure that the position detection baffle 82 can be pressed to the first switch 84 after being squeezed by the rail.

[0029] The top surface of the shift block 106 is higher than the top surface of the roller 4, and the length of the shift block 106 is less than the distance between the third fixed seat 101 and the support frame 1. The top surface of the shift block 106 is higher than the top surface of the roller 4 to ensure that the shift block 106 can fully contact the rail, and the length of the shift block 106 is less than the distance between the third fixed seat 101 and the support frame 1 to ensure that there are no obstacles in the moving path of the shift block 106.

[0030] A guide slope 12 is provided between the support frame 1 and the rail storage platform 11, and a limit plate 13 is fixedly connected to the top of the rail storage platform 11. After the rail is removed from the roller 4, it will slide to the top of the rail storage platform 11 through the guide slope 12 for storage, thereby preventing the rail from directly falling to the top of the rail storage platform 11 and damaging the rail storage platform 11. The limit plate 13 can limit the rail that slides to the top of the rail storage platform 11, thereby preventing the rail from sliding out of the rail storage platform 11 due to inertia after sliding to the rail storage platform 11.

[0031] A plurality of buffer springs 14 are fixedly connected to the inner wall of the limit plate 13, and a buffer plate 15 is fixedly connected to one end of the buffer spring 14 away from the limit plate 13. When the rail contacts the limit plate 13, the buffer plate 15 will slide along the inner wall of the limit plate 13 and make the buffer spring 14 expand and contract, so as to buffer the collision between the rail and the limit plate 13 and prevent the rail and the limit plate 13 from being damaged due to the collision.

[0032] Specific implementation method: First, the driving motor 5 drives the first rotating rod 3 to rotate through the pulley 6 and the belt 7. The rotating first rotating rod 3 drives the other first rotating rods 3 to rotate synchronously through the pulley 6 and the belt 7, thereby driving the roller 4 connected to the first rotating rod 3 to rotate, so that the rail placed on the top of the roller 4 can be transported;

[0033] When the front of the rail contacts the position detection baffle 82, the front of the rail will press down the position detection baffle 82 so that the position detection baffle 82 rotates around the second fixed seat 81 until the position detection baffle 82 presses the first switch 84. During this process, the torsion spring 83 will be deformed after being squeezed by the position detection baffle 82, and then the rail will continue to be transported forward. When the tail of the rail leaves the position detection baffle 82, the torsion spring 83 will recover and push the position detection baffle 82 back to its original position. After pressing the first switch 84, after a delay of several minutes, the roller 4 will stop rotating and the track switching motor 103 will start, and the track switching will start. The motor 103 will drive the second rotating rod 102 in the third fixed seat 101 to rotate, and then drive the sprocket 104 connected to the surface of the second rotating rod 102 to rotate and drive the chain 105 to run. As the chain 105 runs, the shifting block 106 connected to the outer side thereof will contact and push the rail to make it separate from the top of the roller 4. The rail separated from the top of the roller 4 will eventually fall to the top of the rail storage platform 11 for storage. As the chain 105 continues to run, the shifting block 106 will press the second switch 85, and the roller 4 will continue to rotate at this time, and the rail transfer drive assembly 10 will stop running, so that the rail can continue to be transported.

[0034] Due to the difference in lengths of different rails, the shift block 106 may not be able to smoothly make the rail detach from the top of the roller 4 when pushing the rail. At this time, the adjusting motor 92 can be started, and the adjusting motor 92 will drive the screw 91 to rotate, and the guide rod 94 will make the adjusting seat 93 move along the screw 91, thereby driving the shift block 106 in the rail transfer drive assembly 10 to move, so that the position of the shift block 106 can be adjusted according to the length of the rail, thereby expanding the scope of use of the device.

[0035] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
