Description

Technical Field

[0001] The present application relates to the technical field of material transportation, and in particular to a curved hoisting conveyor. Background Art

[0002] Material handling involves workers moving materials from one location to another, or from one machine to another. Loading, transporting, and unloading all involve human interaction, which can lead to numerous disadvantages: First, materials can be easily contaminated and damaged through human contact, particularly in the pharmaceutical industry; second, work efficiency is low; and third, accidents often occur during material handling due to improper handling methods, slippery hands, and fatigue.

[0003] To address these issues, various lifting and transport equipment, manipulators, AGVs, and automated assembly lines have rapidly emerged and developed. AGVs primarily address the difficulties and inefficiencies associated with traditional manual forklifts in collecting data during material transport. However, AGVs cannot fully utilize factory space (primarily the airspace above the factory floor). Consequently, cranes and conveyors are often used, with bridge cranes being the most widely used.

[0004] When existing bridge crane conveyors operate on curved tracks, due to the structural limitations of their traveling mechanisms, they are unable to flexibly adapt to changes in the curvature of the curved tracks, resulting in unstable operation and even possible derailment or jamming. In addition, traditional rail trolleys lack an effective return mechanism after passing through a curved track, which may cause the traveling mechanism to deviate from the straight track and report an obstacle, reducing the efficiency of material transportation.

DETAILED DESCRIPTION

[0019] In order to make the objectives, technical solutions and advantages of this application more clear, the present application is further described in detail below in conjunction with examples and drawings. The schematic implementation methods of this application and their descriptions are only used to explain this application and are not intended to limit this application.

[0020] See also Figures 1 to 5The embodiment of the present application provides a curved hoisting conveyor, which includes a first walking mechanism 10, a second walking mechanism 11, a bottom plate 12, an elastic member 15 and a lifting mechanism 13; the first walking mechanism 10 is used to cooperate with the transport rail 14, so that the first walking mechanism 10 can move along the length direction of the transport rail 14 on the transport rail 14; the second walking mechanism 11 is arranged at intervals with the first walking mechanism 10 and is used to cooperate with the transport rail 14, so that the second walking mechanism 11 can move along the length direction of the transport rail 14 on the transport rail 14, the first walking mechanism 10 and the second The walking mechanism 11 is a two-part rail trolley; the first walking mechanism 10 and the second walking mechanism 11 are rotatably connected to the base plate 12, which means that the first walking mechanism 10 and the second walking mechanism 11 can rotate on the base plate 12, respectively. The rotation center axes of the first walking mechanism 10 and the second walking mechanism 11 are parallel to each other. When the first walking mechanism 10 or the second walking mechanism 11 rotates, it is equivalent to the rail trolley as a whole performing a certain bending action; the elastic member 15 is connected between the first walking mechanism 10 and the second walking mechanism 11 to make the first walking mechanism 10 and the second walking mechanism 11 rotate. The initial arrangement direction of the track trolley is maintained, that is, when the elastic member 15 does not provide elastic force, the first walking mechanism 10 and the second walking mechanism 11 are arranged along the initial arrangement direction. Under this arrangement, the track trolley is suitable for walking on a straight track. When the track trolley enters a curved track, the first walking mechanism 10 or the second walking mechanism 11 rotates on the base plate 12. The first walking mechanism 10 and the second walking mechanism 11 force the elastic member 15 to undergo elastic deformation, so that the entire track trolley can adapt to the curvature of the curved track and bend. Moreover, since the elastic member 15 has good flexibility, as the first walking mechanism The first traveling mechanism 10 or the second traveling mechanism 11 continuously enters the curved track, and the entire rail trolley can adapt to the change of the curvature of the curved track and bend flexibly. When the first traveling mechanism 10 or the second traveling mechanism 11 comes out of the curve, the first traveling mechanism 10 and the second traveling mechanism 11 are arranged along the initial arrangement direction under the elastic force of the elastic member 15, that is, the rail trolley returns to the center by itself to run stably on the straight track; the lifting mechanism 13 is connected to the base plate 12 and is used to lift materials, and the lifting mechanism 13 lifts the materials, and the lifting mechanism 13 transports the materials under the traction provided by the first traveling mechanism 10 and the second traveling mechanism 11.

[0021] Since the curved hoisting conveyor provided in the present application performs hoisting operations on materials, after the rail trolley enters the curved track, the material will swing violently along the arc under the action of inertia and centrifugal force, and it is difficult to return to the initial hanging state, which is not conducive to maintaining the stability of the material. In order to alleviate the violent swing of the material, in some optional embodiments, the lifting mechanism 13 is configured with a sling, the free end of the sling is connected to the bottom plate 12, and the sling is provided with a movable pulley for connecting the material container, which means that the material container is no longer connected to the free end of the sling. After the material container is connected to the movable pulley, due to the gravity of the material container, a large friction force is formed between the movable pulley and the sling, and the friction force will effectively limit the relative sliding of the movable pulley and the sling, and the sling also forms a V-shaped section. Such a lifting method can slow down the violent swing of the material to a certain extent, and is conducive to the material quickly returning to the initial hanging state after the swing.

[0022] In some optional embodiments, see Figure 6 The lifting mechanism 13 may specifically include a connecting frame 133, a brake 131, a drum 132 and a lifting drive source; the connecting frame 133 is connected to the base plate 12, and the connecting frame 133 can be designed as a horizontal plate connected to the base plate 12 and two side plates connected to the horizontal plate, and the horizontal plate and the two side plates together form a U-shaped structure; the brake 131 has a first component 1311 and a second component 1312, and a friction plate 1316 is provided on the first component 1311, wherein the second component 1312 is connected to the connecting frame 133, and the first component 1311 is rotatably connected to the connecting frame 133 The brake 131 is configured to form a rotation limit with the second component 1312 when the rotation speed of the first component 1311 reaches a predetermined value; the reel 132 is rotatably connected to the first component 1311, and the reel 132 abuts against the friction plate 1316. The friction plate 1316 can be made into an annular sheet structure with a certain thickness. The friction plate 1316 is sleeved on the reel 132, and the inner side of the friction plate 1316 abuts against the side of the reel 132, wherein the sling is connected to the reel 132; the lifting drive source is connected to the connecting frame 133 and cooperates with the reel 132 to drive the reel 132 to rotate.

[0023] In the embodiment of the present application, the first component 1311 and the second component 1312 form a passively driven brake 131, which mainly plays a flexible braking role when the rail trolley lifting system is delayed or the power is accidentally cut off. Specifically, when the lifting drive source accidentally cuts off the power or the lifting drive source receives a delay in the control signal, the drum 132 will accelerate and rotate by itself under the action of the gravity of the material. When the lifting drive source is energized or receives a control signal, the drum 132 will be braked immediately. The material will vibrate more strongly under the action of inertia, which may cause damage to the material; after the first component 1311 and the second component 1312 are set, when the drum 132 rotates, the friction force provided by the friction plate 1316 will drive the second component 1312 to rotate synchronously. As the rotation speed of the drum 132 increases, the rotation speed of the second component 1312 The speed will reach a predetermined value. At this time, the second component 1312 and the first component 1311 will interact with each other to limit the rotation of the second component 1312. Since the reel 132 can rotate relative to the second component 1312 and the reel 132 and the friction plate 1316 adopt abutment cooperation method, the reel 132 will not stop immediately with the second component 1312, but will continue to rotate on the second component 1312. Due to the friction force provided by the friction plate 1316, the speed of the reel 132 will gradually decrease until it is zero. That is to say, the friction plate 1316 in the embodiment of the present application serves as a transmission component between the reel 132 and the second component 1312 on the one hand, and as a deceleration component of the reel 132 on the other hand. Compared with instantaneous braking of the reel 132, the movement of the material will be softer, and the material shaking phenomenon will be greatly reduced, which is conducive to ensuring the integrity of the material.

[0024] The first member 1311 can limit the rotation of the second member 1312 by friction, fluid pressure, or mechanical contact force. In order to ensure that the brake 131 can exert a stable and effective braking effect on the reel 132, the first member 1311 and the second member 1312 are suitable for limiting the rotation of the second member 1312 by mechanical limiting, that is, the second member 1312 is restricted from rotating under the mechanical contact force applied by the first member 1311. Figure 7-Figure 8As shown, in some optional embodiments, the first component 1311 is configured as a ratchet, which is rotatably connected to the side plate of the connecting frame 133, and the ratchet can rotate around its own axis. A toggle member 1313 is connected to the ratchet, and the toggle member 1313 can be specifically constructed as a disc-shaped structure. The disc surface of the toggle member 1313 fits the plate surface of the ratchet, and a plurality of toggle blocks extend from the side of the toggle member 1313, and the plurality of toggle blocks are evenly distributed around the axis of the ratchet; the second component 1312 is elastically rotatably connected to the connecting frame 133, and the second component 1312 is located on one side of the first component 1311 and is connected to the connecting frame The side plate on 133 is elastically rotatably connected, which means that after the second member 1312 is rotated under the action of an external force, it can automatically return to its initial state under the action of the elastic force, wherein the second member 1312 has a toggle end 13121 located on both sides of the rotation center axis and a pawl end 13122 capable of cooperating with the ratchet, and the toggle end 13121 is configured to form a sliding contact with the toggle member 1313 when the toggle member 1313 rotates with the ratchet, which means that the height of the toggle end 13121 relative to the side plate is equivalent to the height of the toggle member 1313 relative to the side plate, and the heights of the two can be the same or have a certain height. A certain gap is formed, as long as it is ensured that the toggle member 1313 can form mechanical contact with the toggle end 13121. In the initial state, the toggle end 13121 is located within the rotation circle of the toggle member 1313 and the pawl end 13122 is located outside the rotation circle of the ratchet. As a result, when the ratchet starts to rotate under the drive of the reel 132, the ratchet and the pawl end 13122 will not form a match, and the toggle end 13121 can form a sliding contact with the toggle block. The second member 1312 swings elastically under the action of centrifugal force. As the ratchet speed increases, the toggle block exerts a greater force on the toggle end 13121. The degree of rotation is getting larger and larger, and the elastic swing amplitude of the second component 1312 is getting larger and larger. When the rotation speed of the ratchet reaches a predetermined value, the elastic swing amplitude of the second component 1312 also reaches a predetermined value. At this time, the pawl end 13122 enters the rotation circumference of the ratchet teeth, and the pawl end 13122 can engage with the ratchet, and the ratchet can be mechanically limited. The reel 132 continues to rotate under the action of the gravity of the material. The reel 132 has a rotation tendency through the transmission action of the friction plate 1316, so the engagement state of the ratchet and the pawl end 13122 will be maintained to provide a stable braking effect.

[0025] In some optional embodiments, the toggle end 13121 is configured as a cylinder. The cylinder has a smooth outer surface, which can form a smaller contact area when the toggle end 13121 contacts the toggle block, thereby reducing the contact friction between the toggle end 13121 and the toggle block, and at the same time reducing the friction loss between the toggle end 13121 and the toggle block.

[0026] In some optional embodiments, the toggle end 13121 is configured as a roller. In this configuration, when the toggle end 13121 and the toggle block are in contact with each other, the toggle end 13121 can rotate on the second member 1312 due to the friction force, which can reduce the relative sliding between the toggle end 13121 and the toggle block, thereby further reducing the friction loss between the toggle end 13121 and the toggle block.

[0027] In some optional embodiments, a swing arm 1314 is connected to the second component 1312, the free end of the swing arm 1314 is rotatably connected to one end of the elastic telescopic member 1315, and the other end of the elastic telescopic member 1315 is rotatably connected to the connecting frame 133, so that the elastic telescopic member 1315 applies torque to the swing arm 1314 through its own elastic force.

[0028] In the embodiment of the present application, an elastic telescopic member 1315 is used in conjunction with a swing arm 1314 to provide elastic force for the second member 1312, rather than providing a torsion spring between the second member 1312 and the connecting frame 133. This can facilitate the maintenance of the device, and the elastic telescopic member 1315 can be easily replaced for materials of different weights.

[0029] In some optional embodiments, the elastic telescopic member 1315 is configured as a tension spring.

[0030] In the embodiment of the present application, the tension spring can bend. If the rotation between the tension spring and the connecting frame 133 or the tension spring and the swing arm 1314 is not sensitive enough, the tension spring can still provide elastic force to the second component 1312 when it bends itself, ensuring that the second component 1312 has a stable and reliable braking effect; compared with the rod-shaped elastic telescopic part 1315 such as a hydraulic rod, the requirements for the direction of the driving force are lower. For example, the swing arm 1314 in the embodiment of the present application rotates with the second component 1312, and the direction of the force applied by the swing arm 1314 to the elastic telescopic part 1315 is a nonlinear direction. If the elastic telescopic part 1315 is a rod-shaped elastic telescopic part 1315 such as a hydraulic rod, its rotation on the connecting frame 133 is not sensitive enough, which may cause the elastic telescopic part 1315 to be not sensitive enough, and in severe cases, jamming may occur.
