Detailed Implementation

[0026] The present invention will be further described below through specific embodiments.

[0027] Reference Figures 1 to 8 As shown, a continuous lifting device includes a lifting frame 1, multiple lifting frames 2 that can be moved up and down in the lifting frame 1, multiple floor connection mechanisms 3 that are spaced apart in the lifting frame 1 in the vertical direction, and a lifting mechanism 4 that is installed on the lifting frame 1 and connected to drive the lifting frames 2 to move up and down. The multiple floor connection devices 3 are respectively opposite to multiple conveying floors.

[0028] The floor-to-floor connection mechanism 3 includes a connection frame 5 mounted on the lifting frame 1 and two connection conveying components 6 spaced apart on the connection frame 5. Each connection conveying component 6 includes two connection conveying parts 7 mounted opposite each other on the connection frame 5 and two flipping components 8 mounted on the connection frame 5 to drive the two connection conveying parts 7 to flip. The two connection conveying parts 7 are spaced apart on the connection frame 5 in a horizontal direction to transport the logistics boxes on the lifting frame 2 outward or receive the logistics boxes from the corresponding floor. During operation, the flipping components 8 can drive the opposite connection conveying parts 7 to flip downward and store them on one side of the connection frame 5, so that the lifting frame 2 loaded with logistics boxes can pass between the two connection conveying parts 7 in the stored state.

[0029] The connecting conveyor 7 includes two conveyor belts 71 arranged opposite each other, a drive unit 72 arranged on the connecting frame 5 to connect and drive the two conveyor belts 71 to drive the logistics box, two limiting plates 73 respectively arranged on the outer side of the two conveyor belts 71, multiple connecting rollers 74 arranged at intervals on one side of the connecting frame 5 to guide the logistics box to be transported horizontally outward, and two guide rods 75 arranged opposite each other on the connecting frame 5 on both sides of the multiple connecting rollers 74. The two conveyor belts 71 can be flipped upward to the bottom of the logistics box supported on the lifting frame 2. The drive unit 72 can drive the two conveyor belts 71 to work and transport the logistics box horizontally outward. The setting of the two limiting plates 73 can prevent the conveyor belts from deviating during the process of receiving the logistics box, and ensure that the logistics box after receiving can be stably transported outward by the conveyor belts 71.

[0030] The drive unit 73 includes a synchronizing rod 721 connected between two conveyor belts 71, two bearing seats 722 connected to the synchronizing rod 721 and mounted on the connecting frame 5, and a drive motor 723 connected to one end of the synchronizing rod 721. The connecting frame 5 is provided with two support seats 51 for mounting the two bearing seats 722. Through the cooperation between the support seats 51 and the bearing seats 722, a certain supporting force is provided when the conveyor belt 71 receives the logistics box.

[0031] The flipping assembly 8 includes a mounting base 81 disposed on the connecting frame 5, a flipping rod 82 connected between the two conveyor belts 71, and a flipping cylinder 83 movably disposed on the mounting base 81 and connected to the flipping rod 82 at its front end.

[0032] The lifting mechanism 4 includes a lifting seat 41 mounted on the top of the lifting frame 1, a dual-axis lifting motor 42 mounted on the lifting seat 41, two rotating sprockets 43 mounted on the two output shafts of the dual-axis lifting motor 42, and two transmission components 44 mounted on the lifting frame 1 and connected to the two rotating sprockets 43 respectively. A plurality of lifting frames 2 are spaced apart between the two transmission components 44.

[0033] The transmission assembly 44 includes a first transmission sprocket 441 rotatably mounted on the top of the lifting frame 1 opposite to the rotating sprocket 43 on the same side; a second transmission sprocket 442 coaxially arranged with the first transmission sprocket 441; a first transmission chain 443 disposed between the rotating sprocket 43 and the first transmission sprocket 441; a third transmission sprocket 444 disposed at the bottom of the lifting frame 1 vertically opposite to the second transmission sprocket 442; a second transmission chain 445 disposed between the second transmission sprocket 442 and the third transmission sprocket 444; and a chain disposed on the lifting frame 1. A tensioning member 446 is used to adjust the tension of the second transmission chain 445 between the third transmission sprocket 444 and the second transmission sprocket 442 of the two transmission components 44 are staggered relative to each other. The lifting frame 2 is disposed between the second transmission chains 445 of the two transmission components 44, and its two ends are respectively connected to the same side of the two second transmission chains 445. That is, one end of the lifting frame 2 is connected to the left side of one of the second transmission chains, and the other end is connected to the left side of the other second transmission chain, so that the lifting frame 2 can be moved up and down cyclically between the two second transmission chains 445.

[0034] The lifting frame 2 includes a main body section 21 for supporting the logistics box, two connecting sections 22 that are staggered on both sides of the main body section 21 and connected to the opposite second transmission chains 445, and multiple limiting blocks 23 that are respectively set on the two connecting sections 22. When the logistics box enters the lifting frame 2, it is supported on the main body section 21 and located between the opposite limiting blocks 23. The main body section 21 forms a clearance area 24 for the conveyor belt 71 to rotate, that is, two clearance areas 24 are respectively set on the left and right sides of the main body section 21 to ensure the normal rotation of the conveyor belt 71, so that the logistics box can be stably transported between the lifting frame 2 and the opposite floor connection mechanism 3. When the lifting frame 2 is not carrying a logistics box and the opposite two conveyor belts 71 are rotated upward and in the transport state, the lifting frame 2 without a logistics box can pass between the opposite two conveyor belts 71 on the connecting conveyor 7.

[0035] Tensioning component 446 includes an adjusting plate 4461 connected to the end of a third transmission sprocket 444 on the lifting frame 1, a first adjusting block 4462 on the adjusting plate 4461, a second adjusting block 4463 on the lifting frame 1 opposite to the first adjusting block 4462, an adjusting screw 4464 between the first adjusting block 4462 and the second adjusting block 4463, a first adjusting nut 4465 abutting against the first adjusting block 4462 and cooperating with the adjusting screw 4464, and a second adjusting nut 4466 abutting against the second adjusting block 4463 and cooperating with the adjusting screw 4464. The adjusting plate 4461 is provided with... The connecting hole 4467 is connected to the end of the third transmission sprocket 444. The lifting frame 1 has a strip-shaped adjustment hole 11 through which the end of the third transmission sprocket 444 passes. The connecting hole 4467 is opposite to the strip-shaped adjustment hole 11. When adjusting the tension of the second transmission chain 445, the second adjusting nut 4466 is loosened, and the adjusting screw 4464 is moved up or down, thereby driving the adjusting plate 4461 to move up or down, so that the third transmission sprocket 444 moves up or down. After the position is determined, the second adjusting nut 4466 is locked to fix the position of the adjusting plate 4461, thus completing the adjustment of the tension of the second transmission chain 445.

[0036] When a logistics box needs to be transported from one floor to another, the flipping component 8 drives the opposite connecting conveyor 7 to flip upward, putting the conveyor belt 71 in a conveying state. The driving component 72 drives the two opposite conveyor belts 71 of the connecting conveyor 7 to rotate, allowing the logistics box to enter and be supported on the two opposite connecting conveyor 7. The lifting mechanism 4 drives the lifting frame 2 to move to support the bottom of the logistics box. At this time, the flipping component 8 drives the opposite connecting conveyor 7 to flip downward, putting the conveyor belt 71 in a storage state. The lifting frame 2 moves to the corresponding delivery floor under the action of the lifting mechanism 4. When the lifting frame 2 moves to the corresponding delivery floor, the flipping component 8 drives the opposite connecting conveyor 7 to flip upward and support the bottom of the logistics box. The driving component 72 simultaneously drives the two conveyor belts 71 to work, allowing the logistics box to be transported outward to the corresponding delivery floor. The lifting frame 2 continues to move through the two connecting conveyor 7 without the obstruction of the logistics box, so as to realize the cyclical movement of the lifting frame 2 on the lifting frame 1, transporting the logistics box to the corresponding floor.

[0037] This application sets up multiple layer-level connecting mechanisms 3, each corresponding to a different floor, for receiving or transporting logistics boxes. The structure of the connecting conveyor assembly 6 is further defined. Two spaced connecting conveyor components 7, in conjunction with opposing flipping components 8, allow the connecting conveyor components 7 to be stored on one side of the connecting frame 1 during the upward or downward lifting of the lifting frame 2, without affecting the vertical transport of the logistics boxes. When a logistics box reaches the corresponding floor, the flipping components 8 control the opposing connecting conveyor components 7 to flip upward to receive the logistics box on the lifting frame 2 and transport it outward. After transport, the flipping components 8 control the opposing connecting conveyor components 7 to flip downward again and store them on one side of the connecting frame 5. Throughout the process, the lifting frame 2 can continuously and cyclically move back and forth in the vertical direction, eliminating the need to stop and wait for goods to enter or leave, effectively improving the transport efficiency of the logistics boxes.

All equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the specification of the present utility model shall still fall within the scope of the patent of the present utility model.
