Description

Technical Field

[0001] The present application relates to the technical field of lifting mechanisms, and in particular to a logistics cargo elevator. Background Art

[0002] During the logistics transportation process, there is a height difference between the entrance and exit of standard equipment and the logistics line. Usually, a hoist is required to complete the high and low docking work. The hoist is a mechanical equipment that transports by changing potential energy. It completes the transportation by loading the goods on the carrying plate of the conveyor and then driving the carrying plate to move up and down.

[0003] After the goods are transported to a specified height by the elevator, they need to be discharged from the load plate. The general practice is to install a conveyor belt on the load plate and use the conveyor belt to output the goods. However, when the number of goods placed on the load plate is large, the process of outputting the goods from the load plate via the conveyor belt can easily cause the stacked goods to be output together, which can easily lead to congestion at the output port, thereby resulting in low transportation efficiency. Summary of the invention

[0004] In order to improve the output efficiency of a material cargo elevator when outputting goods, the present application provides a logistics cargo elevator.

[0005] The present application provides a logistics cargo elevator, which includes a frame, a load-bearing plate that reciprocates and rises and falls along the height direction of the frame, and a lifting member for driving the load-bearing plate to rise and fall. The elevator is characterized in that it also includes a moving component and a conveying component, the load-bearing plate includes a plurality of sub-plates, the moving component is used to drive each sub-plate to slide in a direction away from the other sub-plates, and the conveying component is used to convey the cargo on the surface of each sub-plate respectively.

[0006] By adopting the above technical solution, the carrier plate is split into several sub-plates, and the conveying assembly is used to output the goods on the surface of each sub-plate respectively, thereby reducing the situation where the goods are stacked together for output. In addition, the moving assembly is used to drive the sub-plates to move away from each other. This method can separate the goods located between two adjacent sub-plates, so that the goods can move to any of the sub-plates during the movement of the sub-plates, which is convenient for the subsequent use of the conveying assembly to realize the output of the goods on a single sub-plate.

[0007] Preferably, the number of the split panels is three, one of which is a transition panel, and the other two are side panels, the two side panels are located on both sides of the transition panel, and the moving assembly includes a lifting member, which is used to drive the side panels to slide along the height direction of the frame, and can make the height of the side panels higher than the height of the transition panels during the upward movement of the side panels.

[0008] By adopting the above technical solution, the lifting member is used to drive the side panel to rise and fall relative to the transition panel, so that a height difference is formed between the side panel and the transition panel, and the height difference is used to separate the two sub-panels from each other. In the process, the goods located at the junction of the side panel and the transition panel can also be moved to the side panel or the transition panel, so that the goods on the surface of the side panel and the transition panel can be smoothly output through the conveying components respectively.

[0009] Preferably, the lifting member includes a linkage frame and a cylinder, the cylinder is installed on the frame, the cylinder driving end is connected to the linkage frame, the linkage frame is located below the bearing plate, and the linkage frame is simultaneously connected to the lower surfaces of the two side plates.

[0010] By adopting the above technical solution, since there is a transition plate between the two side panels, it is highly unlikely that there will be goods that can contact the two side panels at the same time. Therefore, the two side panels can be lifted and lowered simultaneously relative to the transition plate. Accordingly, the present application utilizes a combined structure of a linkage frame and a cylinder to realize the reciprocating lifting of the two side panels along the height direction. When the side panels are separated from each other relative to the transition plate, the power driving source is reduced, thereby optimizing the effect of energy saving and cost reduction.

[0011] Preferably, the side plate includes a base plate and an inclined plate rotatably connected to the top of the base plate, the linkage frame is connected to the lower surface of the base plate, and the moving assembly also includes an inclined driving member, which is used to drive the inclined plate to tilt during the process of the base plate being raised and lowered relative to the transition plate, and when the base plate moves up relative to the transition plate, the side of the inclined plate close to the transition plate tilts upward.

[0012] By adopting the above technical solution, the inclined plate is driven to tilt using the inclined driving member, thereby cooperating with the height difference between the bottom plate and the transition plate, and further driving the movement of the goods at the junction between the inclined plate and the transition plate, so that such goods can be moved to the side plate under the action of the inclined side plate.

[0013] Preferably, the tilting drive member includes a rotating rod, a docking gear, and a docking rack; the rotating rod is rotatably connected to the upper surface of the base plate, the outer periphery of the rotating rod is provided with an arc-shaped protrusion along its circumference, and the upper surface of the base plate is provided with a clearance hole for the arc-shaped protrusion to pass through, the docking gear is sleeved on the rotating rod, the docking rack is meshed with the docking gear, and the length direction of the docking rack is parallel to the lifting direction of the base plate, and when the arc-shaped protrusion rotates with the rotating rod and passes through the clearance hole, the side of the arc-shaped protrusion away from the rotating rod abuts against the lower surface of the tilting plate, so that the side of the tilting plate close to the transition plate tilts upward.

[0014] By adopting the above technical solution, when the base plate moves upward driven by the lifting member, the docking gear rotates under the meshing action of the docking rack, thereby driving the rotating rod to rotate. The arc-shaped protrusion rotates out of the clearance hole as the rotating rod rotates and pushes the inclined plate upward, so that the side of the inclined plate close to the transition plate tilts upward.

[0015] Preferably, the arc-shaped protrusion is arranged along the length direction of the rotating rod, and the surface of the arc-shaped protrusion is also provided with a plurality of flexible convex strips along its length direction, and the surface of the inclined plate near each flexible convex strip is provided with a through hole for the flexible convex strip to pass through.

[0016] By adopting the above technical solution, when the arc-shaped protrusion contacts the lower surface of the inclined plate, the flexible protrusion that rotates with the arc-shaped protrusion passes through the through hole and is located on the upper surface of the inclined plate, so that the arc-shaped protrusion is used to contact and divide the goods in the length direction of the inclined plate, thereby reducing the situation where goods are stacked on the surface of the inclined plate.

[0017] Preferably, the conveying assembly includes a docking plate and a conveying member, and the docking plate and the conveying member are arranged in a one-to-one correspondence with the split plate. The docking rack is installed on the corresponding docking plate, and the conveying member is used to drive the docking plate to slide in a direction away from the frame. The bottom plate and the inclined plate are located in the sliding direction of the corresponding docking plate; a strip groove is provided on the lower surface of the bottom plate for the linkage frame to be inserted.

[0018] By adopting the above technical solution, the conveying member is used to drive the docking plate to slide in the direction away from the frame, and during the sliding process, the docking plate is used to push the bottom plate and the inclined plate, so that the bottom plate and the inclined plate are driven by the docking plate to move in the direction close to or away from the frame, thereby realizing the output of goods.

[0019] Preferably, the conveying assembly further comprises a conveyor belt arranged on the surface of the transition plate, and the conveyor belt is parallel to the sliding direction of the docking plate.

[0020] By adopting the above-mentioned technical solution, a conveyor belt is used to realize the output of goods on the surface of the transition plate, and the present application further limits the conveying direction of the conveyor belt. In combination with the aforementioned inclination direction of the side plate, it can be known that the goods on the side plate will inevitably be output under the guiding action of the inclined plate. Therefore, the conveying direction of the goods by the two side plates and the conveying direction of the conveyor belt are different. This can also realize the multi-directional output of the goods and further optimize the diversion effect of the goods.

[0021] Preferably, the conveyor belt surface and the inclined plate surface are both provided with flexible buffer pads.

[0022] By adopting the above technical solution, the provision of the flexible buffer pad can reduce the impact force of the goods against the transition plate or the inclined plate during the separation process, thereby protecting the goods and reducing the risk of damage during the collision.

[0023] Preferably, a side wall of the docking plate corresponding to the transition plate, which is away from the transition plate, is also provided with a plurality of push rods, and the push rods are distributed along the height direction of the docking plate. The side wall of the docking plate is also provided with a push member for driving the push rod to penetrate the docking plate and slide, and the sliding direction of the push rod is parallel to the sliding direction of the docking plate.

[0024] By adopting the above technical solution, the push rod and the push member are used to accelerate the acquisition on the output transition plate, and a plurality of push rods are arranged along the height direction of the docking plate, so that the goods at different heights can be output separately, further realizing the diversion of goods.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. Split the carrier plate into several sub-plates, and use the conveying assembly to output the goods on the surface of each sub-plate respectively, so as to reduce the situation where the goods are piled together for output. In addition, use the moving assembly to drive the sub-plates to move away from each other. This method can separate the goods between two adjacent sub-plates, so that the goods can move to any of the sub-plates during the movement of the sub-plates, which is convenient for the subsequent use of the conveying assembly to realize the output of the goods on a single sub-plate; 2. Use the lifting parts to drive the side plate to rise and fall relative to the transition plate, so as to form a height difference between the side plate and the transition plate, and use the height difference to separate the two sub-plates from each other. In the process, the goods located at the junction of the side plate and the transition plate can also be moved to the side plate or the transition plate, so as to realize the smooth output of the goods on the surface of the side plate and the transition plate through the conveying components.

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] The present application embodiment discloses a logistics cargo elevator. Figure 1 and Figure 2 The logistics cargo elevator includes a frame 1, on which a lifting member 11 and a bearing plate 2 are arranged. The lifting member 11 is used to drive the bearing plate 2 to slide back and forth along the height direction of the frame 1. Specifically, the lifting member 11 can be a combination structure of a motor screw rod, or a combination structure of a wire rope, a rotating shaft for winding the wire rope, and a motor for driving the rotating shaft to rotate, wherein the end of the wire rope is connected to the bearing plate 2. The lifting member 11 shown in the accompanying drawings of this embodiment is a combination structure of a motor screw rod. A support plate 12 is arranged on the side wall of the frame 1 and below the bearing plate 2, and a surrounding plate 13 is arranged on the upper surface of the support plate 12 and outside the bearing plate 2. The bearing plate 2 includes a plurality of sub-plates arranged along the width direction of the frame 1. Specifically, the number of sub-plates is three, one of which is a transition plate 21, and the other two sub-plates are side plates 22, and the side plates 22 are arranged on both sides of the transition plate 21. The logistics cargo elevator also includes a moving component 3 and a conveying component 4. The moving component 3 is used to drive the transition plate 21 and the side plate 22 to move and separate them from each other during the movement. The conveying component 4 is used to convey the cargo on the surface of the transition plate 21 and the side plate 22 respectively.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The moving assembly 3 includes a lifting member 31 and a tilting driving member 32; the lifting member 31 includes a linkage frame 311 and a cylinder 312, and the tilting driving member 32 includes a rotating rod 321, a docking gear 322, and a docking rack 323; the side plate 22 includes a bottom plate 221 and an inclined plate 222 rotatably connected to the upper surface of the bottom plate 221, and the rotational connection position of the inclined plate 222 and the bottom plate 221 is located on the side of the bottom plate 221 away from the transition plate 21.

[0034] Reference Figure 2 and Figure 3 The bottom plate 221 is attached to the upper surface of the support plate 12, the cylinder 312 is installed on the lower surface of the support plate 12, the driving end of the cylinder 312 is connected to the linkage frame 311, the linkage frame 311 penetrates the support plate 12 and is connected to the lower surface of the bottom plate 221, and a strip groove for inserting the linkage frame 311 is opened on the lower surface of the bottom plate 221, and the strip groove is opened along the length direction of the bottom plate 221; a clearance hole 2211 is opened on the upper surface of the bottom plate 221 along the thickness direction, the rotating rod 321 is rotatably connected in the clearance hole 2211, the docking gear 322 is fixedly sleeved on the end of the rotating rod 321, the docking gear 322 is meshed with the docking rack 323, and the docking rack 323 is arranged at the end of the frame 1 along the height direction of the frame 1.

[0035] Reference Figure 2 , Figure 3 and Figure 4 The surface of the rotating rod 321 is provided with an arc-shaped protrusion 324 along its length direction. The outer diameter of the rotating rod 321 at the arc-shaped protrusion 324 gradually increases or decreases along the circumference of the rotating rod 321. When the lifting member 31 drives the bottom plate 221 to move upward, the meshing action of the docking rack 323 and the docking gear 322 causes the docking gear 322 to rotate, and then causes the rotating rod 321 to rotate. When the arc-shaped protrusion 324 rotates to the outer periphery of the give way hole 2211 with the rotating rod 321, the surface of the arc-shaped protrusion 324 contacts the lower surface of the inclined plate 222, and causes the inclined plate 222 to rotate and tilt in the direction away from the transition plate 21 under the contact of the arc-shaped protrusion 324.

[0036] Reference Figure 2 , Figure 3 and Figure 4 The surface of the arc-shaped protrusion 324 is evenly connected with flexible ridges 3241 along its length direction, and the surface of the inclined plate 222 near each flexible ridge 3241 is penetrated with a through hole 2221 for the flexible ridge 3241 to be inserted. When the arc-shaped protrusion 324 contacts the lower surface of the inclined plate 222 to make the inclined plate 222 tilt, the flexible ridge 3241 will pass through the through hole 2221 and protrude from the upper surface of the inclined plate 222, thereby playing a role of pushing and evacuating the upper surface of the inclined plate 222, reducing the situation where goods are stacked on the surface of the inclined plate 222.

[0037] Reference Figure 2 and Figure 3The conveying assembly 4 includes a docking plate 41, a conveying member 42 and a conveyor belt 43. The docking plate 41 is arranged in a one-to-one correspondence with the split plate, and the docking plate 41 is located at the end of the corresponding split plate. The docking rack 323 is fixedly connected to the side wall of the corresponding docking plate 41. The ends of the bottom plate 221 and the transition plate 21 are both provided with T-blocks, and the T-blocks are inserted into the side walls of the corresponding docking plates 41. The side walls of the docking plate 41 located at the bottom plate 221 are provided with T-slots 411 for inserting the T-blocks along their height direction; the conveying member 42 can specifically be a combination structure of a motor screw rod, which is used to drive the docking plate 41 to slide back and forth in a direction away from the frame 1 (in the direction indicated by the arrow X in the figure), and the sliding of the docking plate 41 drives the bottom plate 221 and the transition plate 21 to slide back and forth.

[0038] The conveyor belt 43 is arranged on the upper surface of the transition plate 21, and the conveying direction of the conveyor belt 43 is parallel to the sliding direction of the docking plate 41, so as to output the goods on the transition plate 21. The surface of the conveyor belt 43, the side wall of the enclosure 13 near the side plate 22, and the upper surface of the side plate 22 are all connected with a flexible buffer pad 431, which can be made of rubber.

[0039] The side wall of the docking plate 41 corresponding to the transition plate 21, which is away from the transition plate 21, is also evenly arranged with a plurality of push rods 412 along the height direction of the docking plate 41. The docking plate 41 is provided with a push member 413 for driving the push rod to slide in a direction parallel to the sliding direction of the docking plate 41, so that the push rod 412 penetrates the docking plate 41 and moves to the top of the transition plate 21; the push member 413 can be a cylinder.

[0040] The implementation principle of a logistics cargo elevator in an embodiment of the present application is as follows: using the lifting member 11 to move the load-bearing plate 2 down to a height at which materials can be loaded, and then using a conveyor belt 43 or manual methods to transport the goods to the load-bearing plate 2. After the transportation is completed, the lifting member 11 is used again to move the load-bearing plate 2 to a height at which materials need to be unloaded, and then the lifting member 31 is used to drive the two side plates 22 to move up. During this process, the two side plates 22 will tilt in a direction away from the transition plate 21, thereby dividing the goods into three parts. Then, the conveying member 42 is started to drive the docking plate 41 to slide in a direction away from the frame 1, so that the transition plate 21 and the side plate 22 are both separated from the enclosure 13, and then the goods on the side plate 22 will be discharged under the guidance of the inclined side plate 22, and the goods on the transition plate 21 will be separated from the transition plate 21 under the transportation of the conveyor belt 43, thereby finally realizing the diversion and transportation of the goods.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
