Description

Technical Field

[0001] This utility model relates to the field of monorail hoisting turnout technology, and in particular to a pneumatic monorail hoisting turnout. Background Technology

[0002] In current technology, pneumatic monorail hoisting turnouts are typically developed to improve the efficiency and safety of monorail transportation in coal mines and meet the development needs of coal mine production. They achieve turnout reversal through pneumatic means, offering convenient and efficient operation. Furthermore, they are equipped with locking devices to ensure the movable rail remains locked and does not disengage, keeping the turnout in a secure and stable state and effectively preventing safety accidents such as locomotive derailment.

[0003] However, existing technologies still have shortcomings, such as the following:

[0004] When railcars are at switch intersections, collisions can occur. Due to the lack of efficient buffering mechanisms, the impact force is difficult to absorb effectively, easily causing structural damage to the equipment, such as deformation and breakage of key components. This can also lead to track misalignment and displacement. This not only results in equipment downtime for maintenance, affecting operational continuity, but also poses a serious threat to operational safety, including derailment and other safety hazards, increasing the risk of accidents and failing to meet the high standards of reliability and safety required in industrial settings. Utility Model Content

[0005] The purpose of this utility model is to provide a pneumatic monorail hoisting turnout to solve the problem mentioned in the background art that the lack of an efficient buffer structure when railcars collide can easily lead to equipment damage or track misalignment, affecting operational safety.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A pneumatic monorail lifting turnout includes a lifting turnout structure. A buffer structure is bolted to one end of the right side of the lifting turnout structure. The lifting turnout structure includes a main frame. A fixing plate is installed on the outer wall of the inner side of the main frame. A large air cylinder is installed on the outer wall of the right side of the main frame.

[0008] The buffer structure includes a buffer frame, a limiting plate installed on the inner side of the buffer frame, an mounting plate installed on the top of the buffer frame, a support clamp plate installed on the outer wall of the top of the buffer frame, and a fixing block installed on the top of the buffer frame and inside the support clamp plate.

[0009] Preferably, L-shaped plates are rotatably connected to the outer walls on both sides of the fixing block, a connecting plate is rotatably connected to the inner side of the other end of the L-shaped plate, a rotating rod is rotatably connected to the inner sides of both ends of the connecting plate, a support plate is rotatably connected to the outer wall of the rotating rod, a lifting plate is installed on one side of the support plate, a lifting plate is installed at the bottom of the lifting plate, and a buffer tube is installed at the bottom of the lifting plate.

[0010] Preferably, a push cylinder is installed at one end of the buffer tube, an exhaust hole is opened on the outer wall of the buffer tube, a buffer spring is movably installed on the inner side of the buffer tube, a push rod is slidably connected to the inner side of the buffer tube and at one end of the buffer spring, a collision plate is rotatably connected to the inner side of one end of the push rod, a positioning frame is installed at one end of the outer wall of the push rod, and a limit groove is installed on the inner side of the buffer frame.

[0011] Preferably, the inner cavity of the support clamp is provided with a shrinkage groove, and a tensioning frame is installed on the outer wall of one side of the support clamp and on the side of the shrinkage groove.

[0012] Preferably, a small cylinder is installed on the outer wall of the stretching frame, and a retraction rod is installed at one end of the small cylinder.

[0013] Preferably, a locking block is installed at one end of the retractable rod and inside the retractable groove, and a return spring is movably sleeved on the outer wall of the retractable rod and inside the retractable groove.

[0014] Preferably, an adjusting plate is rotatably connected to the outer wall of the top of the fixed plate, and one end of the top of the adjusting plate is rotatably connected to one end of the atmospheric cylinder.

[0015] Preferably, a fixing frame is installed on the inner side of the main frame, and right-angle frames are rotatably connected to the left and right sides of the fixing frame. A pull rod is rotatably connected to one end of the right-angle frame, and a warning sign is rotatably connected to one end of the pull rod. A track is installed at the bottom of the adjusting plate, and a synchronization plate is installed at the top of the track.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The buffer tube adopts a dual buffering mechanism of "buffer spring + compressed air". When the collision plate is impacted, the push rod simultaneously squeezes the buffer spring and the air in the tube, and releases the air pressure energy through the exhaust hole. With the sliding limit of the positioning frame in the limit groove, it can quickly absorb the collision energy of the railcar, reduce the damage of the impact load to the turnout structure, effectively extend the service life of the equipment, and is suitable for high-frequency collision scenarios in heavy-load transportation.

[0018] 2. After absorbing the impact energy, the lifting plate rotates synchronously, triggering the locking mechanism between the L-shaped plate and the locking block, raising the liner plate to the top of the support clamp, thus increasing the overall height of the buffer structure by 15-20cm. This design breaks the limitations of traditional fixed buffer height, quickly reserving sufficient passage space for the railcar after a collision, avoiding vehicle jamming or secondary collisions caused by the buffer structure falling back, significantly improving the smoothness of the turnout in continuous operation, and is especially suitable for automated transportation scenarios that require frequent adjustments to track height.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-5 As shown, a pneumatic monorail lifting turnout includes a lifting turnout structure 1, a buffer structure 2 is bolted to one end of the right side of the lifting turnout structure 1 and connected to the buffer structure 2, a fixing plate 15 is installed on the outer wall of the inner side of the main frame 11 to limit one end of the tail of the adjusting plate 13, and a large air cylinder 12 is installed on the outer wall of the right side of the main frame 11 to pull one end of the bottom of the adjusting plate 13 through one end of the large air cylinder 12.

[0027] The buffer structure 2 includes a buffer frame 21, and a limiting plate 23 is installed on the inner side of the buffer frame 21 to limit the lifting plate 25. An mounting plate 22 is installed on the top of the buffer frame 21 for mounting the buffer frame 21. A support clamp 256 is installed on the outer wall of the top of the buffer frame 21. When the support plate 251 rotates to the support clamp 256, it is supported by the support clamp 256. A fixing block 255 is installed on the top of the buffer frame 21, inside the support clamp 256, to limit and fix one end of the L-shaped plate 254. L-shaped plates 254 are rotatably connected to the outer walls of both sides of block 255, allowing one end of the L-shaped plates 254 to rotate on both sides of the fixed block 255. A connecting plate 253 is rotatably connected to the inner side of the other end of the L-shaped plates 254, and rotating rods 252 are rotatably connected to the inner sides of both ends of the connecting plate 253, facilitating the rotation of the support plate 251. Thus, the support plate 251, rotatably connected to the outer wall of the rotating rods 252, can rotate. A lifting plate 25 is installed on one side of the support plate 251, which drives the buffer tube 26 and the lifting plate 24, thereby lifting... A lifting plate 24 is installed at the bottom of plate 25. A buffer tube 26 is installed at the bottom of the lifting plate 24, which can drive the buffer tube 26 to rise. A buffer tube 26 is also installed at the bottom of the support plate 251. The buffer tube 26 provides cushioning through its inner structure. A push cylinder 261 is installed at one end of the buffer tube 26. The push cylinder 261 pushes the push rod 264 inside the buffer tube 26 to facilitate its reset. An exhaust hole 263 is provided on the outer wall of the buffer tube 26 to facilitate the release of air from inside the buffer tube 26. The device is equipped with a buffer spring 262, which buffers the push rod 264 at the inner end of the buffer tube 26. The push rod 264 is slidably connected to the inner end of the buffer tube 26 and the end of the buffer spring 262 to provide a buffering distance. The inner side of one end of the push rod 264 is rotatably connected to the collision plate 265 to directly receive the collision. A positioning frame 266 is installed at one end of the outer wall of the push rod 264, and a limit groove 231 is installed on the inner side of the buffer frame 21, so that one side of the top of the positioning frame 266 can be limited and slid within the limit groove 231.

[0028] It should be noted that in this embodiment, when the collision plate 265 is impacted, it compresses the push rod 264. One end of the push rod 264 compresses the air inside the buffer tube 26 and the buffer spring 262. Simultaneously, the positioning frame 266 slides within the limiting groove 231, thereby expelling the compressed air through the exhaust hole 263. This allows the air inside the buffer tube 26 and the buffer spring 262 to provide a buffering effect. When the push cylinder 261 is activated, the push rod... One end of the cylinder 261 pushes the push rod 264, thereby resetting the push rod 264. When the push rod 264 squeezes the buffer tube 26, it causes the positioning frame 266 to disengage from the inner side of the limiting groove 231. At the same time, the lifting plate 25 is subjected to the squeezing force. Through the rotation of the fixing block 255, the bottom of the liner plate 251 rotates to the upper surface of the support clamp 256, so that the bottom of the liner plate 251 rests on the bottom of the support clamp 256. This causes the lifting plate 25 and the buffer tube 26 to adjust their height, allowing the railcar to pass.

[0029] The inner cavity of the support clamp 256 is provided with a contraction groove 2563, which facilitates the retraction of the locking block 2565 into the inner side of the contraction groove 2563. A tension frame 2561 is installed on the outer wall of one side of the support clamp 2566, located on the side of the contraction groove 2563. A small cylinder 2562 is installed on the outer wall of the tension frame 2561, and a contraction rod 2566 is installed at one end of the small cylinder 2562. When the small cylinder 2562 is activated, the contraction rod 2566 can be pulled into the inner side of the tension frame 2561. A locking block 2565 is installed at one end of the contraction rod 2566, located inside the contraction groove 2563, which causes the L-shaped plate 254 to rotate to the inner side of the support clamp 2566 and simultaneously limits its movement. A return spring 2564 is movably sleeved on the outer wall of the contraction rod 2566, located inside the contraction groove 2563, to reset the locking block 2565.

[0030] It should be noted that in this embodiment, when the L-shaped plate 254 rotates into the inner side of the support clamp 256, the outer wall on the right side of the L-shaped plate 254 is used to squeeze the locking block 2565. The locking block 2565 is squeezed and retracts into the inner side of the shrinkage groove 2563. At the same time, the return spring 2564 is used to reset it, so that it limits the connection plate 253. If the small cylinder 2562 is activated, the small cylinder 2562 pulls the shrinkage rod 2566, which is pulled to the inner side of the tension frame 2561, thereby pulling the locking block 2565 into the inner side of the shrinkage groove 2563.

[0031] An adjusting plate 13 is rotatably connected to the outer wall of the top of the fixed plate 15, and one end of the top of the adjusting plate 13 is rotatably connected to one end of the atmospheric cylinder 12. The swing direction of the adjusting plate 13 can be controlled by starting the atmospheric cylinder 12. A track 131 is installed at the bottom of the adjusting plate 13. When the adjusting plate 13 swings, it drives the track 131 to adjust the track. A synchronization plate 132 is installed on the top of the track 131 to synchronize with the synchronization plate 132. A fixed frame 14 is installed on the inner side of the main frame 11, and right angles are rotatably connected to the left and right sides of the fixed frame 14. The frame 141 uses a synchronous plate 132 to adjust the rotation angle of the right-angle frame 141. One end of the right-angle frame 141 is rotatably connected to a pull rod 142. When the right-angle frame 141 is pushed by the synchronous plate 132, it pulls the pull rod 142, thereby pulling the warning sign 143 rotatably connected to one end of the pull rod 142. When the warning sign 143 is pulled, the part where the warning sign 143 is connected to the pull rod 142 rotates. The warning sign 143 is limited by one end of the main frame 11, which controls the surface of the warning sign 143 to tilt up.

[0032] It should be noted that in this embodiment, when the atmospheric cylinder 12 is activated, one end of the tail of the adjusting plate 13 rotates on the upper surface of the fixed plate 15, thereby causing one end of the atmospheric cylinder 12 to pull or push the adjusting plate 13 to rotate, controlling the adjusting plate 13 to swing, causing the bottom of the adjusting plate 13 to drive the track 131 to adjust the track position, and causing the synchronous plate 132 to swing, causing the left and right sides of the synchronous plate 132 to push one end of the right angle frame 141. When the right angle frame 141 is pulled, the other end of the right angle frame 141 pulls the pull rod 142, causing the other end of the pull rod 142 to pull the warning sign 143. While the warning sign 143 is being pulled, it is also limited by one end of the main frame 11, thereby controlling the warning sign 143 to tilt up.

[0033] The working principle of this utility model is as follows: When the atmospheric cylinder 12 is activated, one end of the adjusting plate 13 rotates on the upper surface of the fixed plate 15, thereby pulling or pushing the adjusting plate 13 to rotate. This controls the adjusting plate 13 to swing, causing the bottom of the adjusting plate 13 to drive the track 131 to adjust its position. This, in turn, causes the synchronous plate 132 to swing, pushing one end of the right-angle frame 141 from both sides. When the right-angle frame 141 is pulled, the other end of the frame pulls the lever 142, which in turn pulls the warning sign 143. Simultaneously, the warning sign 143 is also limited by one end of the main frame 11, thus controlling the warning sign 143 to tilt upwards.

[0034] When the collision plate 265 is impacted, it compresses the push rod 264. One end of the push rod 264 compresses the air inside the buffer tube 26 and the buffer spring 262. Simultaneously, the positioning frame 266 slides within the limiting groove 231, thus allowing the compressed air to be discharged through the exhaust port 263. The air inside the buffer tube 26 and the buffer spring 262 then provide a buffering effect. When the push cylinder 261 is activated, it compresses the air inside the push cylinder 261... The end of the push rod 264 is pushed, thereby resetting the push rod 264. When the push rod 264 squeezes the buffer tube 26, it causes the positioning frame 266 to disengage from the inner side of the limiting groove 231. At the same time, the lifting plate 25 is subjected to the squeezing force. Through the rotation of the fixing block 255, the bottom of the liner plate 251 rotates to the upper surface of the support clamp 256, so that the bottom of the liner plate 251 rests on the bottom of the support clamp 256. This causes the lifting plate 25 and the buffer tube 26 to adjust their height, allowing the railcar to pass.

[0035] When the L-shaped plate 254 rotates into the inner side of the support clamp 256, the outer wall on the right side of the L-shaped plate 254 presses the locking block 2565. The locking block 2565 is compressed and shrinks into the inner side of the shrinkage groove 2563. At the same time, the return spring 2564 is used to reset it, so that it limits the connection plate 253. If the small cylinder 2562 is activated, the small cylinder 2562 pulls the shrinkage rod 2566, which is pulled to the inner side of the tension frame 2561, thereby pulling the locking block 2565 into the inner side of the shrinkage groove 2563.
