Detailed Description

The invention is further described with reference to the accompanying drawings and the detailed description.

Example 1:

as shown in fig. 1-6, a platform conveying mechanism comprises a frame 1 and a trolley 5. The trolley 5 is a rectangular platform. The upper surface of the trolley 5 is provided with a raised stop strip. The stop bars are arranged along the periphery of the upper surface of the trolley 5. The trolley 5 is fixedly connected with a trolley middle shaft 52. The trolley central axis 52 is located in the central axis of the platform of the trolley 5. The two ends of the middle axle 52 of the trolley extend out of the platform of the trolley 5. The middle shaft 52 of the trolley is fixedly connected with a connecting block 51. The connecting block 51 is rectangular and is fixed with one end of a middle shaft 52 of the trolley. The connecting block 51 is perpendicular to the horizontal plane.

The frame 1 is a rectangular frame. The frame 1 is rotatably connected with a rotating wheel 6 through a main shaft. The main shaft is positioned in the middle of the frame 1 and is arranged in parallel with the horizontal plane. The main shaft is connected with the frame 1 through a bearing. The rotating wheel 6 is connected with the main shaft through a key. The rotating wheel 6 is fixedly connected with a balance wheel 4. The balance wheel 4 is disc-shaped and is coaxially fixed with the rotating wheel 6.

The main shaft is sleeved with a balance ring 2. The balance ring 2 is annular. The circular ring surface of the balance ring 2 is parallel to the surface of the rotating wheel 6. The balance wheel 4 is spaced from the rotating wheel 6. The connecting block 51 falls in this space.

The balance ring 2 is connected with a plurality of vertical balancers 3. The vertical balancer 3 includes: lower shaft 31, riser 32, upper shaft 33, connecting plate 34, balancing piece 35. The vertical plate 32 is a strip-shaped flat plate. The large area is the surface of the riser 32. One ends of the lower shaft 31 and the upper shaft 33 are respectively fixed with two ends of the vertical plate 32, and the other ends are suspended. The lower shaft 31, the vertical plate 32 and the upper shaft 33 are connected in a Z shape. The connecting plate 34 and the balance weight 35 are rectangular plate-shaped. The area is large and is the surface of the connecting plate 34 and the balance weight 35. The side of the connecting plate 34 is fixed with the surface of the balance weight 35 near the edge. The free end of the upper shaft 33 is fixed on the surface of the connecting plate 34. The upper shaft 33, the connecting plate 34 and the balance weight 35 are connected in a Z shape. The vertical plates 32 and the connecting plates 34 are parallel and spaced apart. The surface of the weight 35 is perpendicular to the surface of the riser 32.

The suspended end of the lower shaft 31 is connected with the balance ring 2 through a bearing. The lower shaft 31 is perpendicular to the torus of the gimbal ring 2. The balance ring 2 is parallel to the surface of the vertical plate 32 and has a gap. The balance wheel 4 is provided with a bearing near the edge, and the upper shaft 33 is positioned between the vertical plate 32 and the connecting plate 34 and is connected with the bearing. The vertical plate 32 and the connecting plate 34 are positioned on two sides of the balance wheel 4, and respectively have a gap with two surfaces of the balance wheel 4. The upper shaft 33 is rotatably connected to the balance wheel 4 near the edge surface. The upper shaft 33 is perpendicular to the surface of the balance wheel 4. The counterweight 35 falls in the space between the balance wheel 4 and the turning wheel 6.

The number of vertical balancers 3 is related to the distance between the trolley central axes 51 of adjacent trolleys 5. The vertical balancers 3 are uniformly distributed on the rotating wheel 6 near the edge, and the arc length between two adjacent vertical balancers 3 is equal to the distance between the trolley middle shafts 51 of the adjacent trolleys 5. The weight of the balancing ring 2 is larger than the sum of the weight of the trolley 5 and the weight of the loaded mail of the trolley 5. The balance ring 2 is suspended on the side of the balance ring 2 by means of a vertical balancer 3 connected to a balance wheel 4 to offset its own weight. The centre of circle of the ring deviates downwards from the centre of circle of the rotating wheel 6 under the action of the self weight of the balance ring 2. The plane of the counterweight 35 remains vertically horizontal.

The cart central shaft 52 is connected with a chain. The chains are provided with a pair and are positioned at two sides of the trolley 5. The ends of the trolley middle shaft 52 extending out of the two sides of the trolley 5 are respectively sleeved with one sleeve of the two chains. The middle axle 52 of the trolley passes through one end face of the sleeve and is fixedly connected with the connecting block 51. The rotating wheel 6 is a chain wheel. Two chain wheels are respectively positioned at two sides of the trolley 5. The chain wheel on one side is fixed with the balance wheel 4. The chain is engaged with the sprocket. The chain wheel rotates to drive the chain wheel to move horizontally, and the trolley 5 also moves horizontally. When the chain sleeved with the middle shaft 52 of the trolley is meshed with the chain wheel, the balance weight 35 is attached to the connecting block 51. The weight of the balancing ring 2 is larger than the sum of the weight of the trolley 5 and the weight of the loaded mail of the trolley 5. The counterweight 35 remains vertically horizontal. The weight 35 forces the connecting block 51 to maintain a vertical horizontal plane. The cart central axle 52 cannot rotate. The cart central axle 52 moves along the sprocket periphery as the chain engages the sprocket. When the trolley 5 passes through the chain wheel arc, the plane of the platform of the trolley 5 is always kept parallel to the horizontal plane. Thus, mail carried by the carriage 5 is carried from the upper level to the lower level or from the lower level to the upper level, and is not dropped off all the way on the platform of the carriage 5.

Example 2:

in order to have a light structure and reduce noise and oil pollution, the middle shaft 52 of the trolley is connected with a toothed belt. The tooth-shaped belts are provided with a pair of teeth and are positioned at two sides of the trolley 5. The ends of the trolley middle shaft 52 extending out of the two sides of the trolley 5 are respectively fixed with the planes of the two toothed belts. One end of the connecting rod extends out of the toothed belt, and the other side surface of the connecting rod is fixedly connected with the connecting block 51. The runner 6 is a gear. Two gears are respectively positioned at two sides of the trolley 5. The gear on one side is fixed with the balance wheel 4. The toothed belt is meshed with the gear. The gear rotates to drive the toothed belt to translate, and the trolley 5 also translates. When the teeth fixedly connected with the middle shaft 52 of the trolley are meshed with the gear, the balance weight 35 is attached to the connecting block 51. The balance ring 2 keeps the balance weight 35 in a vertical horizontal plane due to the self weight. The weight 35 forces the connecting block 51 to maintain a vertical horizontal plane. The cart central axle 52 cannot rotate. The trolley middle shaft 52 moves along the periphery of the gear along with the engagement of the toothed belt and the gear. When the trolley 5 passes through the gear arc, the plane of the platform of the trolley 5 is always kept parallel to the horizontal plane, and the mails loaded on the trolley 5 are moved from the upper layer to the lower layer or from the lower layer to the upper layer and are always on the platform of the trolley 5 without falling.
