Description

Technical Field

[0001] This utility model relates to the field of logistics and transportation technology, and in particular to a logistics turnover device for logistics and transportation. Background Technology

[0002] Logistics transportation services are a comprehensive service network consisting of five modes of transportation: rail, road, waterway, air, and pipeline. Efficiency is optimized through economies of scale and distance, and the spatial transfer of goods is completed in accordance with the principles of timeliness, accuracy, safety, and economy. Rail transport handles long-distance transport of bulk goods, road transport focuses on short- and medium-distance distribution with door-to-door flexibility, waterway transport specializes in low-cost bulk cargo transport, and air transport focuses on time-sensitive goods. Since logistics often involves transporting goods from one city to another or multiple cities or even multiple provinces, various transit stations are indispensable in the logistics transportation process. At each transit station, turnover devices are needed to sort and classify the transported goods.

[0003] Existing logistics transportation turnover devices mainly consist of wheeled pallets and grids. During turnover, items are placed inside the grids and then pushed away. However, due to the short turnover process, items are often not neatly arranged when placed on the turnover device, resulting in uneven force on the items at the top. This makes it easy for items to fall when the turnover device turns. Furthermore, after the items have been turnovered, workers need to step on the brakes on the wheels to bring the turnover device to a complete stop. Sometimes, in order to achieve rapid turnover, braking measures are not taken. However, this poses a safety hazard. To prevent items from falling and to achieve rapid braking of the turnover device, a new logistics turnover device for logistics transportation is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a logistics turnover device for logistics transportation. It has the advantages of being able to cover and block the items on the turnover device to prevent them from falling during the turnover process, and to quickly limit the position of the turnover device after the items have been turned to a designated position, thereby reducing safety hazards. This solves the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: a logistics turnover device for logistics transportation, comprising four support legs, two side frames, and two movable frames. The side walls of the support legs are fixedly connected to a base plate for holding objects. A caster wheel is installed on the left side of the bottom surface of the base plate, and a travel wheel is installed on the right side of the bottom surface of the base plate. A cover device is provided on the support leg, and a lifting mechanism is provided on the cover device. Two sets of mounting brackets are symmetrically fixedly connected to the side walls of the movable frames. A pin is slidably connected to each set of mounting brackets, and a handle is fixedly connected to the outer surface of the pin. Limiting rings are fixedly connected to the side walls of the support legs at the corresponding positions of the mounting brackets.

[0006] Preferably, the sealing device includes a pin, which is rotatably connected to the upper side wall of each set of support legs. Each end of the pin extends out of the outer surface of the support leg and is fixedly sleeved with a bracket for support. A fixed shaft for support is fixedly connected between two brackets.

[0007] Preferably, the outer surface of the fixed shaft is provided with a rotating drum, and the outer surface of the rotating drum is wound with a protective felt cloth, and a hook for fixing the felt cloth is fixedly connected to the middle of the end of the felt cloth away from the rotating drum.

[0008] Preferably, the lifting mechanism includes a limiting shaft, which is fixedly connected to the upper surface of the bracket near the pin. The outer surface of the pin is fixedly fitted with L-shaped blocks for deflection on both sides of the hook. A pull rope for applying force is fixedly connected to the outer surface of the limiting shaft at the corresponding position of the L-shaped blocks. A directional locking mechanism is provided on the lower part of the side wall of the left supporting leg, and a travel locking mechanism is provided on the lower part of the side wall of the right supporting leg.

[0009] Preferably, the directional locking mechanism includes a movable plate, which is fixedly connected to the lower part of the side wall of a set of support legs on the left side, and a limiting rod for limiting the position is fixedly connected to the side wall of the movable plate facing the caster wheel.

[0010] Preferably, a spring for resetting is sleeved on the outer surface of the limiting rod, a connecting rod is slidably sleeved on the outer surface of the limiting rod, and inclined blocks for locking the direction of the universal wheel are fixedly connected to both ends of the connecting rod.

[0011] Preferably, the position of the inclined block one corresponds to the direction axis of the omnidirectional wheel.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model, through the design of pins, brackets, fixed shafts, rotating cylinders, felt cloth, and hooks, allows the worker to rotate the bracket when an object is placed within the side frame and movable frame and located on the upper side of the base plate. This allows the bracket to be positioned horizontally above the side frame and movable frame, thus limiting the object on the upper side of the base plate. If the height of the object is higher than the height of the side frame and movable frame, the worker can pull the hook and use it to spread out the felt cloth. The hook can then be hung on the pin to limit the spread-out felt cloth. This method of using the spread-out felt cloth to limit the object prevents it from falling during handling.

[0013] 2. This utility model, through the design of a limiting shaft, an L-shaped block, a pull rope, a movable plate, a limiting rod, a spring, a connecting rod, and an inclined block, allows the turnover device to be moved to a designated position. When the items inside the turnover device need to be removed, the support needs to be flipped open from above the side frame. At this time, the deflection of the support causes the pin to deflect synchronously with the L-shaped block, which in turn releases the force applied to the pull rope. This releases the tension applied by the pull rope to the movable plate, causing the spring to push the connecting rod and the inclined block towards the caster wheel. The inclined block then locks onto the underside of the caster wheel, preventing it from rotating further. Simultaneously, spring two moves connecting rod two and inclined block two, causing inclined block two to move towards the traveling wheel, making it contact and abut against the traveling wheel. This limits the traveling wheel, effectively braking the turnover device, simplifying its braking action, and improving safety. Furthermore, when it is necessary to connect the items on the turnover device to the logistics vehicle, simply place the forklift forks in the limiting cylinder and then use the forklift to lift the turnover device to a position level with the logistics vehicle to achieve rapid transfer of items, greatly improving the device's applicability.

[0016] 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.

[0017] Please see Figure 1 , Figure 2 and Figure 3 A logistics turnover device for logistics transportation includes four support legs 1, two side frames 2, and two movable frames 3. The four support legs 1 are divided into left and right groups (left and right orientation referenced). Figure 1Each set of support legs 1 has a side frame 2 fixedly connected to its side wall for supporting and protecting objects. A movable frame 3 is provided between two sets of support legs 1 for easy opening and to prevent objects from falling. Grilles are fixedly installed on the inner sides of both the side frame 2 and the movable frame 3. A handrail 4 is fixedly connected to the upper side wall of each set of support legs 1 for easy operation. A base plate 5 for holding objects is fixedly connected to the side wall of each support leg 1. The base plate 5 is fixedly connected to the bottom end of the side frame 2. The movable frame 3 is hinged to the top surface of the base plate 5. The base plate 5, along with the four support legs 1, two side frames 2, two movable frames 3, and the handrail 4, forms the main body of the turnover device. A caster wheel 6 is installed on the left side of the bottom surface of the base plate 5, and a travel wheel 7 is installed on the right side of the bottom surface of the base plate 5. Support legs 1 are equipped with… The sealing device is equipped with a lifting mechanism. Two sets of mounting brackets 8 are symmetrically fixedly connected to the side wall of the movable frame 3. Each set of mounting brackets 8 is slidably connected with a pin 9. A handle 10 is fixedly connected to the outer surface of the pin 9. A limit ring 11 is fixedly connected to the side wall of the support leg 1 at the corresponding position of the mounting bracket 8. When the objects are stacked randomly, the movable frame 3 on one side can be opened to realize the turnover of goods. Specifically, the staff pulls the handle 10 in the direction of the turnover device, so that the handle 10 moves with the pin 9 and leaves the limit ring 11. Since the movable frame 3 and the base plate 5 are hinged, the movable frame 3 can be deflected independently, causing the side protection of the turnover device to be removed, so that the objects can be transported and turned over.

[0018] Please see Figure 2 and Figure 4 The sealing device includes a pin 101, which is rotatably connected to the upper side wall of each set of support legs 1. Each end of the pin 101 extends out of the outer surface of the support leg 1 and is fixedly sleeved with a bracket 102 for support. A fixed shaft 103 for support is fixedly connected between the two brackets 102. The top opening of the turnover device can be blocked by the deflection of the bracket 102 to prevent the object from falling during turnover.

[0019] Please see Figure 4 A rotating drum 104 is provided on the outer surface of the fixed shaft 103. The rotating drum 104 is rotatably sleeved on the outside of the fixed shaft 103 by a coil spring (the coil spring is a mature existing technology, so it is not described in detail in the figure). One end of the coil spring is fixedly connected to the outer surface of the fixed shaft 103, and the other end of the coil spring is fixedly connected to the inner surface of the rotating drum 104. A protective felt cloth 105 is wound around the outer surface of the rotating drum 104. A hook 106 for fixing the felt cloth 105 is fixedly connected to the middle of the end of the felt cloth 105 away from the rotating drum 104. By pulling the hook 106, the felt cloth 105 is spread out, and the spread-out felt cloth 105 is used to cover the top opening of the turnover device to prevent objects from falling. After the cover is completed, the hook 106 is hung on the pin shaft 101 to limit the position of the felt cloth 105.

[0020] Please see Figures 4-6 The lifting mechanism includes a limiting shaft 107, which is fixedly connected to the upper surface of the bracket 102 near the pin 101. L-shaped blocks 108 for deflection are fixedly sleeved on both sides of the hook 106 on the outer surface of the pin 101. A pull rope 109 for applying force is fixedly connected to the outer surface of the limiting shaft 107 at the corresponding position of the L-shaped blocks 108. The pin 101 deflects the L-shaped blocks 108, causing the pull rope 109 in contact with the L-shaped blocks 108 to be taut by the force of the L-shaped blocks 108, thus applying tension to the pull rope 109. A directional locking mechanism is provided on the lower part of the side wall of the left support leg 1, and a travel locking mechanism is provided on the lower part of the side wall of the right set of support legs 1 (left and right orientation reference). Figure 1 ).

[0021] Please see Figure 5 The directional locking mechanism includes a movable plate 110, which is fixedly connected to the lower part of the side wall of a set of support legs 1 on the left side. A limiting rod 111 for limiting the position is fixedly connected to the side wall of the movable plate 110 facing the universal wheel 6. A spring 112 for resetting is sleeved on the outer surface of the limiting rod 111. A connecting rod 113 is slidably sleeved on the outer surface of the limiting rod 111. One end of the spring 112 is fixedly connected to the movable plate 110, and the other end of the spring 112 is fixedly connected to the connecting rod 113. Both ends of the connecting rod 113 are fixedly connected to inclined blocks 114 for locking the direction of the universal wheel 6. The potential energy is applied to the connecting rod 113 by the spring 112, causing the connecting rod 113 to move with the inclined blocks 114, so that the inclined blocks 114 are stuck at the steering shaft of the universal wheel 6, thereby limiting the steering of the universal wheel 6.

[0022] Please see Figure 6 The travel locking mechanism includes a movable plate 115, which is fixedly connected to the lower part of the side wall of a set of support legs 1 on the right side (see left and right orientation). Figure 1 A limiting rod 116 for limiting the position is fixedly connected to the side wall of the movable plate 115 facing the traveling wheel 7. A reset spring 117 is sleeved on the outer surface of the limiting rod 116. A connecting rod 118 is slidably sleeved on the outer surface of the limiting rod 116. One end of the spring 117 is fixedly connected to the movable plate 115, and the other end of the spring 117 is fixedly connected to the connecting rod 118. Two inclined blocks 119 for locking the position of the traveling wheel 7 are fixedly connected to both ends of the connecting rod 118. The potential energy of the spring 117 is applied to the connecting rod 118, causing the connecting rod 118 to move with the inclined blocks 119, so that the inclined blocks 119 abut against the traveling wheel 7, thereby limiting the position of the traveling wheel 7.

[0023] Please see Figures 5-6The end of the pull rope 109 on the left side, away from the limiting shaft 107, is fixedly connected to the side wall of the connecting rod 113. The movable plate 110 has a through hole corresponding to the pull rope 109 for the pull rope to pass through. The end of the pull rope 109 on the right side, away from the limiting shaft 107, is fixedly connected to the side wall of the connecting rod 118 (left and right orientation reference). Figure 1 The movable plate 115 and the pull rope 109 are also provided with through holes for the pull rope 109 to pass through, so that the pull rope 109 can pass through the movable plate 110 and the movable plate 115 and apply the tension of the pull rope 109 to the connecting rod 113 and the connecting rod 118 respectively. This causes the connecting rod 113 to take the inclined block 114 away from the steering shaft of the universal wheel 6, while the connecting rod 118 will take the inclined block 119 away from the position of the traveling wheel 7, thereby releasing the limit of the universal wheel 6 and the traveling wheel 7. The L-shaped block 108 is located on the path of the pull rope 109. Through the deflection of the pin 101, the pin 101 will deflect the L-shaped block 108, thereby ensuring that the L-shaped block 108 will apply a force to the pull rope 109 during the deflection process.

[0024] Please see Figures 5-6 The position of the first inclined block 114 corresponds to the direction axis of the universal wheel 6, and the position of the second inclined block 119 corresponds to the travel wheel 7.

[0025] Please see Figures 1-2 The lower surface of the base plate 5 is fixedly connected to a limiting cylinder 51 that facilitates the insertion of forklift forks. When the turnover device needs to be moved into the logistics vehicle, the forklift places its forks inside the limiting cylinder 51, and then uses the forklift to lift and move the turnover device.

[0026] Working principle: In the initial state, since the two supports 102 are in a vertical position (e.g. Figure 2As shown), the pull rope 109 is not subjected to the force of the L-shaped block 108, so that the potential energy of spring 112 and spring 217 will act on connecting rod 113 and connecting rod 218 respectively. Connecting rod 113 will push inclined block 114 to the steering shaft of universal wheel 6, thereby limiting the steering of universal wheel 6. Inclined block 219 is pushed to the traveling wheel 7 by connecting rod 218, and the traveling wheel 7 is limited by inclined block 219, so that the turnover device cannot move, which facilitates the workers to move the objects. Then, the workers move the objects to the upper side of the base plate 5 for stacking. After stacking, rotate the bracket 102 so that the bracket 102 blocks the opening of the turnover device. If the height of the object is higher than the height of the side frame 2 and the movable frame 3, pull the hook 106 so that the hook 106 hangs on the top of the base plate 5. On the pin 101, as the hook 106 moves, the felt 105 unfolds, covering the upper items and effectively preventing them from falling off the transfer device. After sealing, as the bracket 102 deflects, the pin 101 deflects the L-shaped block 108, causing the L-shaped block 108 to exert force on the pull rope 109, tightening it. The tightened pull rope then exerts tension on the movable plate 110 and movable plate 115, causing the connecting rod 113 to move away from the steering shaft of the universal wheel 6 along with the inclined block 114, and the connecting rod 118 to move away from the travel wheel 7 along with the inclined block 119. At this point, pushing the handle 4 moves the transfer device. When the transfer device reaches a designated position and items need to be transferred, as the bracket 102 deflects to a vertical position (e.g., ...), the transfer device moves. Figure 2 As shown), the force exerted by the L-shaped block 108 on the pull rope 109 is removed. At this time, the potential energy of the spring 112 is released and acts on the connecting rod 113, causing the connecting rod 113 to once again engage with the inclined block 114 on the steering shaft of the universal wheel 6. Meanwhile, the potential energy of the spring 217 acts on the connecting rod 218, causing the connecting rod 218 to once again move with the inclined block 219 to the travel wheel 7, so that the turnover device can be stably stopped in the designated position. This allows the turnover device to quickly complete the braking measures, improving safety performance. When it is necessary to move the turnover device to a logistics vehicle for item turnover, the fork of the forklift can be placed in the limiting cylinder 51, and then the turnover device can be lifted by using the fork of the fork.
