Abstract
Description
Technical Field
[0001] The utility model relates to the field of hospital intelligent logistics system technology, and particularly relates to an anti-falling rail turning device. Background Technique
[0002] The rail turning device is a component in the hospital rail logistics system. Its function is that when a fire alarm occurs, the track is automatically disconnected. A fireproof window is arranged at the disconnection position of the original track, and the fireproof window is controlled to close by a fire alarm signal. When the rail turning device is in normal use, the movable section of the rail turning device is fixed by a track positioning device to ensure the connection of the track. When a fire occurs, the positioning device is loosened, and the movable section of the rail turning device is pushed open by a compressed air cylinder to disconnect the track and leave a closing passage for the fireproof window.
[0003] After retrieval, a Chinese patent with the Chinese publication number of 202410140749X discloses a rail turning device with accurate positioning in a logistics track. Its static rail, movable rail, and static rail are laid in sequence to form a straight rail type rail turning device; the lower ends of one side static rail and the movable rail are rotatably connected to each other; a cylinder assembly, a fireproof device, and a track positioning device are respectively arranged on one side static rail, the movable rail, and the other side static rail; the piston rod of the cylinder assembly is connected to the fireproof device; the track positioning device includes a first electromagnetic component iron and a first iron block component; a first electromagnet component is arranged on the upper end surface of the other side static rail, and a first iron block component is arranged on the upper end surface of the movable rail; when the movable rail is turned down by the driving of the air cylinder, a fireproof window or a fireproof door is arranged in the spaced space formed between the movable rail and the other side static rail. When the movable rail is turned up by the driving of the air cylinder until the movable rail and the static rail form a straight rail, the first electromagnet component is electrified and magnetically attracted to the first iron block component. The rail turning device with accurate positioning in a logistics track provided by the present invention firmly fixes the movable rail in the working position to ensure accurate positioning.
[0004] In the actual production process, when the rail trolley enters and exits the rail turning device, due to the impact force in the vertical direction generated by gravity, when the power grid power fluctuates too much, the magnetic force between the electromagnet and the iron block is too small to generate a gap. According to the characteristics of the electromagnet, after the gap is generated, the electromagnetic force is greatly reduced, and it is easy to open the rail turning device, and the trolley falls from the rail turning device. Using the electromagnet positioning technology has certain potential safety hazards and is easy to cause property losses. Therefore, an anti-falling rail turning device is proposed to solve the above problems. Utility Model Content

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0036] Refer to Figure 1 , Figure 7 , Figure 8 and Figure 9 , an embodiment provided by the present invention: an anti-falling track turning device, including a first track 1 and a lock head assembly 5. The outside of the first track 1 is fixedly connected with a first rotating shaft fixed end 10, and the first track 1 functions to fix the position of the first rotating shaft fixed end 10. The inner wall of the first rotating shaft fixed end 10 is threadedly connected with a rotating shaft 3, and the first rotating shaft fixed end 10 functions to fix the position of the rotating shaft 3. The outside of the rotating shaft 3 is rotatably connected with a second rotating shaft fixed end 12. The rotation of the second rotating shaft fixed end 12 can drive the rotating shaft 3 to rotate, and when the rotating shaft 3 rotates, the second rotating shaft fixed end 12 can also be kept non-separated from the first rotating shaft fixed end 10.
[0037] The outside of the second rotating shaft fixed end 12 is fixedly connected with a second track 4. The second track 4 functions to fix the position of the second rotating shaft fixed end 12, and the position of the second rotating shaft fixed end 12 is limited to drive the position of the second track 4 and the first track 1 to be limited. The outside of the second track 4 is fixedly connected with a lock head fixing plate 13, and the second track 4 functions to fix the position of the lock head fixing plate 13. The outside of the lock head assembly 5 is installed on the outside of the lock head fixing plate 13, and the lock head fixing plate 13 functions to support and fix the position of the lock head assembly 5. The outside of the lock tongue fixing plate 15 is fixedly connected with a third track 7, and the third track 7 functions to support and fix the position of the lock tongue fixing plate 15. The outside of the lock tongue fixing plate 15 is installed with a lock tongue housing 16, and the lock tongue housing 16 is used to protect the lock tongue 6.
[0038] Refer to Figures 2 to 3, the lock head assembly 5 includes an unlocking electric cylinder 401. The unlocking electric cylinder 401 is installed outside the lock head fixing plate 13, and the lock head fixing plate 13 serves to fix the position of the unlocking electric cylinder 401. The driving end of the unlocking electric cylinder 401 contacts the outside of the lock catch linkage piece 402. When the unlocking electric cylinder 401 is energized, the lock catch linkage piece 402 rotates. The other end of the lock catch linkage piece 402 contacts the outside of the lock catch 404. The lock catch 404 loses the limit of the lock catch linkage piece 402 and rotates, bringing the lock catch to the unlocking state. The lock catch linkage piece 402 is rotatably connected to the outside of the lock head fixing plate 13, and the lock head fixing plate 13 serves to fix the position of the lock catch linkage piece 402, enabling the lock catch linkage piece 402 to rotate around its center when subjected to an external force but not to disengage from the device.
[0039] The lock catch 404 is installed outside the lock head fixing plate 13, and the lock head fixing plate 13 serves to fix the position of the lock catch 404, enabling the lock catch 404 to rotate around its center when subjected to an external force but not to disengage from the device. The lock tongue 6 is detachably connected to the outside of the lock catch 404. When the lock catch 404 is in the unlocking state, the lock tongue 6 loses its limiting function. The lock tongue fixing plate 15 is fixedly connected to the outside of the lock tongue 6, and the lock tongue fixing plate 15 serves to fix the position of the lock tongue 6. The lock head cover 14 is installed outside the lock head fixing plate 13 for protecting the lock head. The limit pin 403 is installed outside the lock head fixing plate 13. During normal operation, the cylinder 2 is in the compressed state, the lock head is in the locked state, and the lock catch 404 is fixed by the lock catch linkage piece 402 and the limit pin 403.
[0040] Refer to Figures 4 to 6 , a connection component for determining whether to connect the track ends is fixedly connected to the outside of the first track 1. The connection component includes a cylinder head fixing part 9. The outside of the cylinder head fixing part 9 is fixedly connected to the outside of the first track 1, and the first track 1 serves to fix the position of the cylinder head fixing part 9. The cylinder 2 is detachably connected to the outside of the cylinder head fixing part 9, and the cylinder head fixing part 9 serves to fix the position of the cylinder 2. The cylinder tail fixing part 11 is fixedly connected to the outside of the second track 4, and the second track 4 serves to support and fix the position of the cylinder tail fixing part 11. The other end of the cylinder 2 is detachably connected to the outside of the cylinder tail fixing part 11. When the cylinder 2 is started, the cylinder 2 can push the cylinder tail fixing part 11, and the movement of the cylinder tail fixing part 11 drives the second track 4 to move.
[0041] There is a fire window passage 8 outside the second track 4. The other end of the fire window passage 8 is arranged outside the third track 7. The second track 4 is opened under the thrust of the cylinder 2, and the rail turner enters the access lock state. When the pressure of the cylinder 2 is completely released, the rail turner is in the open state, and a fire window passage 8 is formed between the second track 4 and the third track 7. To ensure that the movable section can be opened without interference and can maintain a smaller joint with the second track 4 when closed, the outer parts of the second track 4 and the third track 7 are cooperatively chamfered at an angle of 30 degrees.
[0042] Working principle: During normal operation, the cylinder 2 is in a compressed state, the lock head is in a locked state, the lock catch 404 is fixed by the lock catch linkage piece 402 and the limit pin 403, and the lock catch 404 locks the lock tongue 6, thereby ensuring that the second track 4 is in the working position, and the first fixed track section and the second fixed track section are in a connected state, and the trolley can pass normally. If it is necessary to open the rail turner, the unlocking electric cylinder 401 is energized. The driving end of the unlocking electric cylinder 401 rotates the lock catch linkage piece 402. The lock catch 404 loses the limit of the lock catch linkage piece 402 and rotates, so that the lock catch 404 reaches the unlocking state. When the lock catch 404 is in the unlocking state, the lock tongue 6 loses its limiting function. The second track 4 is opened under the thrust of the cylinder 2, and the rail turner enters the access lock state. When the pressure of the cylinder 2 is completely released, the rail turner is in the open state, and a fire window passage 8 is formed between the second track 4 and the third track 7.
[0043] If it is necessary to close the rail turner, manually push the second track 4 to the closed state. The lock head assembly 5 is pushed to the locked state by the lock tongue 6, and the lock tongue 6 is locked, and the rail turner completes the closing operation. It effectively prevents the rail turner from being opened passively when the electromagnetic force is insufficient, thereby ensuring the stability and safety of the track. Ensure that it is firmly locked when the rail turner is in the closed state, and avoid the trolley from falling due to gravity impact or power fluctuation. This improvement not only enhances the safety of the system, but also ensures the smoothness and efficiency of the transportation process and reduces the risk of property loss.
[0044] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
