Abstract

This invention relates to the field of helipad guide rail technology, and discloses a guide rail mechanism for transferring logistics cabinets on a helipad. The mechanism includes a helipad, logistics cabinets fixedly installed on both sides of the helipad, and shelves fixedly installed on the helipad and inside the two logistics cabinets. A movable frame is horizontally slidably installed within the helipad, and a lifting frame is vertically slidably installed on the movable frame. A multi-stage telescopic plate is fixedly installed on the lifting frame. A horizontal drive mechanism and a vertical drive mechanism are fixedly installed on the movable frame. This guide rail mechanism utilizes the magnetic attraction of the magnetic blocks at the ends of the guide plates to bring the inclined surfaces of the two guide plates together in a V-shape. When the end of the second guide rail is inserted between the two guide plates, it slides along the inclined inner wall of the guide plates and eventually simultaneously abuts against the inner walls of both guide plates, causing the two guide plates to flip to a parallel state. The guide plates then slide into the slots, compensating for any missing slots and facilitating better passage of the slide block, reducing jamming.

Description

Technical Field

[0001] This invention relates to the field of helipad guide rail technology, specifically a guide rail mechanism for transferring logistics cabinets on a helipad. Background Technology

[0002] The helipad is the take-off and landing platform for drones. Logistics cabinets are usually symmetrically installed on both sides of the helipad for storing goods and supporting intelligent storage and retrieval. Currently, the receiving and transfer of goods within the helipad are carried out by two separate mechanisms to improve the speed of goods processing. The transfer mechanism consists of a mobile frame, a lifting frame, and a multi-stage telescopic rack. The helipad and the logistics cabinet are connected by a top and bottom guide rail system. After the drone places the goods on the helipad, the receiving mechanism picks up the goods. Then, the multi-stage telescopic rack on the loading platform retrieves the goods from the receiving mechanism and puts them back into the mobile frame. The mobile frame then enters the corresponding logistics cabinet along the guide rail. At the same time, the lifting frame slides on the mobile frame to the corresponding height. After the mobile frame slides to the corresponding position on the logistics cabinet shelf, the multi-stage telescopic rack extends again to store the goods on the shelf. The multi-stage telescopic rack can also extend in both directions to store and retrieve goods on both sides of the shelf in the logistics warehouse. The guide rails that guide the moving frame inside the helipad and the logistics cabinet are of the same model. Current technology typically involves workers using bolts to fix the two sections of the guide rail. However, manual fixing is prone to errors, causing the two sections of the guide rail to malalign. When the rollers or sliders of the moving frame pass through the interface, uneven force can cause localized stress concentration, leading to abnormal wear or even deformation and jamming of the rollers or sliders. This can cause the moving frame to sway or collide with the shelves, resulting in goods falling and being damaged. Over long-term operation, the error between the two sections of the guide rail may continue to increase due to vibration, increasing damage to the guide rail and causing deformation or breakage. This can lead to derailment and collisions of the moving frame, affecting the transfer and storage of goods. Therefore, we propose a guide rail mechanism for transferring goods between helipad logistics cabinets. Summary of the Invention

[0003] The purpose of this invention is to provide a guide rail mechanism for transferring logistics cabinets on a parking apron, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a guide rail mechanism for transferring logistics cabinets on a helipad, comprising a helipad, logistics cabinets fixedly installed on both sides of the helipad, shelves fixedly installed on the helipad and inside the two logistics cabinets, a movable frame slidably installed laterally within the helipad, a lifting frame slidably installed vertically on the movable frame, a multi-stage telescopic plate fixedly installed on the lifting frame, and a lateral drive mechanism for lateral sliding and a vertical drive mechanism for vertical sliding of the lifting frame fixedly installed on the movable frame. Four first guide rails are symmetrically fixedly installed vertically within the helipad. Four second guide rails are symmetrically fixedly installed vertically within each logistics cabinet. The first and second guide rails are of the same model. Four slides that cooperate with the first and second guide rails are fixedly installed at both ends of the moving frame. Guide plates are symmetrically rotatably installed at both ends of each first guide rail. Two slots that cooperate with the guide plates are symmetrically arranged at one end of each second guide rail. The thickness of the guide plate is the same as the depth of the slots. One end of each guide plate is wedge-shaped, and a magnetic block is fixedly installed on the wedge-shaped surface. Every two corresponding magnetic blocks are magnetically attracted to each other.

[0005] Preferably, each of the slide blocks has a limiting plate on both inner walls, and two first springs are symmetrically fixedly connected between each limiting plate and the corresponding inner wall of the slide block. A rotating shaft is fixedly installed at the upper end of each limiting plate, and a sliding groove for limiting the rotating shaft is provided on the inner wall of each slide block. Each rotating shaft is slidably installed in the corresponding sliding groove.

[0006] Preferably, a sliding rod is rotatably connected between each pair of corresponding rotating shafts, two fixed shafts are fixedly installed at both the upper and lower ends of the movable frame, two rotating plates are symmetrically rotatably installed on each fixed shaft, a connecting rope is fixedly connected between each rotating plate and its corresponding sliding rod, two pressure sensing plates for controlling the lateral drive mechanism to stop working are fixedly installed at both the upper and lower ends of the movable frame, a second spring is fixedly connected to one side of each rotating plate and its corresponding pressure sensing plate, and a warning light is fixedly installed on one side of each pressure sensing plate.

[0007] Preferably, each of the rotating shafts is fixedly mounted with a rotating rod, and two parallel connecting rods are provided between every two rotating rods. The two ends of each connecting rod are rotatably connected to the ends of the corresponding two rotating rods, and the two connecting rods and the two rotating rods form a rectangle.

[0008] Preferably, a support plate is fixedly installed on both sides of each first guide rail and both sides of each second guide rail, and an insertion hole is provided at the end of each support plate. Four telescopic rods are symmetrically installed at both ends of the helipad, and a push plate is fixedly installed at the end of each telescopic rod. Four insertion rods that cooperate with the insertion holes are symmetrically fixedly installed on each push plate.

[0009] Preferably, each of the first guide rails has a sliding plate at both ends for blocking the insertion of the plug rod into the socket, each sliding plate is fixedly connected to the corresponding support plate with an elastic rod, and each of the second guide rails has a baffle fixedly installed at one end for limiting the sliding plate.

[0010] Preferably, each guide plate is provided with a positioning hole, and each end of the second guide rail is fixedly installed with a telescopic block that cooperates with the positioning hole.

[0011] Preferably, four pulleys are symmetrically and rotatably mounted on both sides of the lower end of the movable frame, and each of the support plates is provided with a guide groove for limiting the position of the pulleys.

[0012] Preferably, each of the limiting plates is provided with a plurality of ball bearings.

[0013] Preferably, several sponge pads for cleaning the first guide rail and the second guide rail are fixedly installed at both the upper and lower ends of the movable frame.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention utilizes the magnetic attraction of the magnetic blocks at the ends of the guide plates to make the inclined surfaces of the two guide plates fit together and form a V-shape. When the end of the second guide rail is inserted between the two guide plates, it will slide along the inclined surface of the inner wall of the guide plate and eventually abut against the inner wall of both guide plates, causing the two guide plates to flip to a parallel state. The guide plates will slide into the slots to compensate for the lack of slots, making it easier for the slide to pass through and reducing jamming. When the guide plates are flipped to a parallel state with the second guide rail, the telescopic block is completely aligned with the positioning hole. Its own elasticity will push it into the positioning hole. The first guide rail and the second guide rail are connected through the guide plates, which facilitates the docking of the first guide rail and the second guide rail, improves the firmness of the docking, and reduces errors. 2. This invention utilizes the second guide rail to drive the baffle, pushing the end of the slide plate back below the first guide rail. After the slide plate no longer limits the insertion rod, the first guide rail and the second guide rail are connected. The telescopic rod will push the push plate, causing the insertion rod to be inserted into the corresponding insertion rod. This can simultaneously limit the two adjacent first guide rails and the two adjacent second guide rails, further improving the firmness of the connection between the first guide rail and the second guide rail, reducing the errors generated during use. At the same time, the pulley bears most of the weight of the moving frame, reducing the friction when the moving frame slides, reducing the errors caused by friction, and improving the service life of the first guide rail and the second guide rail. 3. This invention utilizes ball bearings on the limiting plate to hold the guide rails on both sides. When the guide rails tilt due to error, the ball bearings on the tilted side will be squeezed by the guide rails, causing the corresponding limiting plate to move along the slide groove into the inner wall of the slide block. The two rotating shafts will drive the slide rod to slide along the slide groove, pulling the connecting rope. The pressure sensed by the pressure sensing plate will increase. The pressure sensing plate can simultaneously detect the tilt of the guide rails at both slide blocks. When the error between the two slide blocks reaches the level requiring repair or replacement, the pressure sensed by the pressure sensing plate will trigger the warning light to illuminate and stop the lateral drive mechanism from working. This prevents excessive friction from causing the moving frame to shake or collide, resulting in goods falling and being damaged. When repairing or replacing the guide rails, observing the warning light will quickly determine which guide rail has an excessive error. Attached Figure Description

[0017] 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.

[0018] Please see Figure 1-11This invention provides a technical solution: a guide rail mechanism for transferring logistics cabinets on a helipad, comprising a helipad 1, logistics cabinets 2 fixedly installed on both sides of the helipad 1, and shelves 3 fixedly installed inside the helipad 1 and the two logistics cabinets 2. A movable frame 4 is slidably installed laterally inside the helipad 1, a lifting frame 5 is slidably installed vertically on the movable frame 4, a multi-stage telescopic plate frame 6 is fixedly installed on the lifting frame 5, a lateral drive mechanism 7 for lateral sliding of the movable frame 4, and a vertical drive mechanism 8 for vertical sliding of the lifting frame 5 (the multi-stage telescopic plate frame 6, the lateral drive mechanism 7, and the vertical drive mechanism 8 are all existing known mechanisms, and therefore will not be described in detail in this invention). The helipad 1 is symmetrically fixed vertically. Four first guide rails 9 are installed, and four second guide rails 10 are symmetrically fixedly installed vertically inside each logistics cabinet 2. The first guide rails 9 and the second guide rails 10 are of the same model. Four slides 26 that cooperate with the first guide rails 9 and the second guide rails 10 are fixedly installed at both ends of the moving frame 4. When goods are transferred, the multi-stage telescopic rack 6 first extends to remove the goods from the receiving mechanism and retracts into the moving frame 4. Then, the horizontal drive mechanism 7 drives the moving frame 4 to slide along the first guide rails 9 to the corresponding second guide rails 10 in the logistics cabinet 2. At the same time, the vertical drive mechanism 8 drives the lifting frame 5 to slide vertically on the moving frame 4, so that the multi-stage telescopic rack 6 moves to the designated position of the shelf 3. Then, the multi-stage telescopic rack 6 can be extended and retracted to transfer goods. For storing and retrieving goods and completing the transfer of goods, each first guide rail 9 has a guide plate 11 symmetrically mounted at both ends. Each second guide rail 10 has two slots 14 symmetrically arranged at one end that mate with the guide plate 11. The thickness of the guide plate 11 is the same as the depth of the slot 14. Each guide plate 11 has a wedge shape at one end, and a magnetic block 13 is fixedly mounted on the wedge surface. Every two corresponding magnetic blocks 13 are magnetically attracted to each other. Each guide plate 11 has a positioning hole 12. Each second guide rail 10 has telescopic blocks 15 fixedly mounted on both sides of its end that mate with the positioning hole 12. In the initial state, when the first guide rail 9 is not connected to the second guide rail 10, the magnetic attraction of the magnetic blocks 13 at the ends of the two guide plates 11 causes the inclined surfaces of the ends of the two guide plates 11 to fit together. The guide plate 11 is V-shaped. When the end of the second guide rail 10 is inserted between the two guide plates 11, the inclined surfaces of the guide plates 11 cannot be further rotated outwards. The end of the second guide rail 10 will slide along the inclined surface of the inner wall of the guide plate 11 and eventually abut against the inner walls of both guide plates 11, causing the two guide plates 11 to rotate to a parallel state. At this time, the guide plate 11 will slide into the slot 14. Since the thickness of the guide plate 11 is the same as the depth of the slot 14, the guide plate 11 can compensate for the lack of the slot 14, making it easier for the slide block 26 to pass through and reducing jamming. During the rotation of the guide plate 11, the end of the telescopic block 15 will be inserted into the positioning hole 12. At this time, the positioning hole 12 is not completely aligned with the telescopic block 15, and the telescopic block 15 cannot be fully inserted into the positioning hole 12.The telescopic block 15 will retract into the second guide rail 10. After the guide plate 11 flips to a state parallel to the second guide rail 10, the telescopic block 15 will be completely aligned with the positioning hole 12. Its own elasticity will push it into the positioning hole 12, connecting the first guide rail 9 and the second guide rail 10 via the guide plate 11. This facilitates the docking of the first guide rail 9 and the second guide rail 10, while also improving the firmness of the docking and reducing errors.

[0019] Each first guide rail 9 and each second guide rail 10 are fixedly mounted with support plates 23 on both sides. Each support plate 23 has an insertion hole 16 at its end. Four telescopic rods 19 are symmetrically installed at both ends of the helipad 1. Each telescopic rod 19 has a push plate 18 fixedly installed at its end. Each push plate 18 has four insertion rods 17 symmetrically fixedly installed on it, which cooperate with the insertion holes 16. Each first guide rail 9 has a sliding plate 21 at both ends to prevent the insertion rods 17 from being inserted into the insertion holes 16. Each sliding plate 21 is fixedly connected to the corresponding support plate 23 with an elastic rod 22. Each second guide rail 10 has one end Each guide rail 21 is fixedly equipped with a baffle 20 for limiting the movement of the slide plate 21. When the first guide rail 9 and the second guide rail 10 are not connected, the elastic rod 22 is in an extended state, pushing the slide plate 21 to be on the movement trajectory of the insertion rod 17, preventing the insertion rod 17 from only being inserted into the insertion hole 16 of the support plate 23 corresponding to the first guide rail 9, and the end of the slide plate 21 extends out of the first guide rail 9. During the connection process between the first guide rail 9 and the second guide rail 10, the baffle 20 will push the end of the slide plate 21 back to below the first guide rail 9 and compress the elastic rod 22. After the slide plate 21 no longer limits the insertion rod 17, the first guide rail 9 and the second guide rail 10 are connected. Once completed, the insertion rod 17 corresponds one-to-one with the insertion hole 16. The telescopic rod 19 will push the push plate 18, causing the insertion rod 17 to be inserted into the corresponding insertion hole 16. By limiting the support plate 23 through the insertion rod 17, the two adjacent first guide rails 9 and the two adjacent second guide rails 10 can be limited simultaneously, further improving the firmness of the connection between the first guide rail 9 and the second guide rail 10 and reducing the errors generated during use. Four pulleys 24 are symmetrically rotated and installed on both sides of the lower end of the moving frame 4. Each support plate 23 is provided with a guide groove 41 for limiting the pulleys 24. Both the upper and lower ends of the moving frame 4 are Several sponge pads 25 are fixedly installed for cleaning the first guide rail 9 and the second guide rail 10. The guide groove 41 limits the pulley 24, which can improve the stability of the movement of the moving frame 4 and reduce the possibility of derailment. At the same time, the pulley 24 bears most of the weight of the moving frame 4, which reduces the friction when the moving frame 4 slides, reduces the error caused by friction, and improves the service life of the first guide rail 9 and the second guide rail 10. In addition, the moving frame 4 can drive the sponge pads 25 to continuously wipe and clean the first guide rail 9 and the second guide rail 10 during the sliding process, reducing the impact of impurities on the sliding.

[0020] Each slide block 26 has a limit plate 27 on both inner walls, and each limit plate 27 has several balls 40 to reduce friction between the slide block 26 and the guide rail. Two first springs 28 are symmetrically fixedly connected between each limit plate 27 and the inner wall of the corresponding slide block 26. A rotating shaft 29 is fixedly installed at the upper end of each limit plate 27. Each slide block 26 has a groove 30 on its inner wall for limiting the rotating shaft 29. Each rotating shaft 29 is slidably installed in its corresponding groove 30. A rotating rod 31 is fixedly installed on each rotating shaft 29. Two parallel connecting rods 32 are provided between every two rotating rods 31. Both ends of each connecting rod 32 are rotatably connected to the ends of the two corresponding rotating rods 31. The two connecting rods 32 and the two rotating rods 31 form a... The rectangular frame 4 has a sliding rod 33 rotatably connected between each pair of corresponding pivots 29. Two fixed pivots 37 are fixedly installed at both the upper and lower ends of the moving frame 4. Two rotating plates 38 are symmetrically rotatably installed on each fixed pivot 37. Each rotating plate 38 is fixedly connected to its corresponding sliding rod 33 by a connecting rope 34. Two pressure sensing plates 35 for controlling the lateral drive mechanism 7 to stop are fixedly installed at both the upper and lower ends of the moving frame 4. A second spring 39 is fixedly connected to one side of each rotating plate 38 and its corresponding pressure sensing plate 35. A warning light 36 is fixedly installed on one side of each pressure sensing plate 35. During the sliding process of the moving frame 4, each slide block 26 slides on the first guide rail 9 and the second guide rail 10. The ball bearings on the two limiting plates 27 inside the slide block 26... The balls 40 will respectively abut against both sides of the guide rail. When the guide rail tilts due to error, the balls 40 on the tilted side will be squeezed by the guide rail, causing the corresponding limiting plate 27 to move along the slide groove 30 into the inner wall of the slide block 26. At the same time, the limiting plate 27 will rotate according to the degree of tilt of the guide rail, and the corresponding first spring 28 will be compressed. Through the connection of two connecting rods 32, and the two connecting rods 32 and two rotating rods 31 forming a rectangle, the two rotating rods 31 will always maintain synchronous sliding and rotation. The two limiting plates 27 in the slide block 26 will also slide and rotate synchronously. The balls 40 on the two limiting plates 27 will always stick to both sides of the guide rail, maintaining good clamping of the guide rail and preventing derailment due to uneven force. When the two limiting plates 27 slide, the two rotating shafts 29 will drive the slide rod 33 along the guide rail. When the slide 30 slides, the limiting plate 27 does not shift initially, and the slide rod 33 is located in the middle position inside the slide block 26, without pulling the connecting rope 34. When the slide rod 33 slides, it pulls the connecting rope 34 and causes the rotating plate 38 to rotate on the fixed shaft 37. The second spring 39 between the fixed shaft 37 and the pressure sensing plate 35 is compressed, and the pressure sensed by the pressure sensing plate 35 increases. The greater the tilt error of the guide rail, the greater the pressure sensed by the pressure sensing plate 35. The moving frame 4 is provided with two slide blocks 26 on each guide rail. When each slide block 26 passes the guide rail, it pulls the corresponding connecting rope 34 according to the tilt degree of the guide rail at that location. The pressure sensing plate 35 can detect the tilt degree of the guide rail at both slide blocks 26 simultaneously.When the error between the two slides 26 reaches a level requiring repair or replacement, the pressure sensed by the pressure sensor 35 will trigger the warning light 36 to illuminate and stop the lateral drive mechanism 7 from working. This prevents excessive friction from causing the moving frame 4 to shake or collide, resulting in goods falling and being damaged. When repairing or replacing the guide rails, observing the illumination of the warning light 36 can quickly determine which guide rail has the excessive error.

[0021] Specifically, when the first guide rail 9 aligns with the second guide rail 10, the end of the second guide rail 10 is inserted between the two guide plates 11. The end of the second guide rail 10 will slide along the inclined inner wall of the guide plate 11 and eventually abut against the inner walls of both guide plates 11, causing the two guide plates 11 to flip to a parallel state. At this time, the guide plates 11 will slide into the slot 14, compensating for the lack of the slot 14 and facilitating the passage of the slide block 26. During the flipping process of the guide plate 11, the telescopic block 15 cannot be fully inserted into the positioning hole 12. The telescopic block 15 will retract into the second guide rail 10. When the guide plate 11 flips to a state parallel to the second guide rail 10, the telescopic block 15 will be fully inserted into the positioning hole. Alignment of 12 and insertion into positioning holes 12 improves the firmness of the connection. At the same time, baffle 20 pushes the end of slide plate 21 back to below the first guide rail 9. After the first guide rail 9 and the second guide rail 10 are connected, telescopic rod 19 pushes push plate 18, so that insertion rod 17 is inserted into the corresponding insertion hole 16. This can limit the two adjacent first guide rails 9 and the two adjacent second guide rails 10 at the same time, further improving the firmness of the connection between the first guide rail 9 and the second guide rail 10. During the sliding process of the moving frame 4, each slide block 26 slides on the first guide rail 9 and the second guide rail 10. The balls 40 on the two limiting plates 27 in the slide block 26 will respectively abut against the guide rail. When the guide rail tilts due to an error, the ball bearing 40 on the tilted side will be squeezed by the guide rail, causing the corresponding limiting plate 27 to move along the slide groove 30 into the inner wall of the slide block 26. At the same time, the limiting plate 27 will rotate according to the degree of tilt of the guide rail. Through the cooperation of the two connecting rods 32 and the two rotating rods 31, the two limiting plates 27 in the slide block 26 will slide and rotate synchronously. The ball bearing 40 on the two limiting plates 27 always sticks to both sides of the guide rail, maintaining good clamping of the guide rail. When the two limiting plates 27 slide, the two rotating shafts 29 will drive the sliding rod 33 to slide along the slide groove 30, pulling the connecting rope 34 and pulling the rotating plate 38 to rotate on the fixed shaft 37. As the pressure sensor plate 35 senses the increased pressure, each slide 26 pulls the corresponding connecting rope 34 according to the tilt of the guide rail when it passes the guide rail. The pressure sensor plate 35 can simultaneously detect the tilt of the guide rail at two slides 26. When the error between the two slides 26 reaches the level that requires repair or replacement, the pressure sensed by the pressure sensor plate 35 will trigger the warning light 36 to light up and stop the horizontal drive mechanism 7 from working. This prevents excessive friction from causing the moving frame 4 to shake or collide, resulting in the goods falling and being damaged. When repairing or replacing the guide rail, the situation of the warning light 36 can be observed to quickly determine which guide rail has an excessive error.
