[0029] The lifting frame 13 is arranged on the sliding frame 3, and the conveying roller 14 for conveying goods in the front-back direction is arranged on the lifting frame 13. The lifting frame 13 is docked with the external conveying line 37 for use, and the conveying line 37 is supported by the conveying line bracket 38. A distance measuring device 12 is arranged on the inner wall of the top of the strip groove 2, and the distance measuring device 12 is directly opposite to the sliding frame 3, and is used to measure the distance between it and the bracket of the sliding frame 3; a plurality of conveying lines 37 are arranged side by side, and the distance measured by the distance measuring device 12 is used for positioning. At a specific distance, the lifting frame 13 is docked with the conveying line 37 for use to form a multi-lifting structure. The lifting frame 13 is a hollow structure, and a power device for driving the conveying roller 14 to rotate is arranged inside it. The power device can drive the conveying roller 14 to rotate forward and reverse, so as to receive the goods or convey the goods out;

[0030] A bottom slide 16 is slidably disposed at the bottom of the lifting frame 13 along the front-rear direction;

[0031] The follower slide 17 is slidably arranged on the inner wall of the strip groove 2 in the vertical direction. The follower slide 17 is located below the sliding frame 3. A connecting plate 18 is rotatably arranged between the follower slide 17 and the bottom slide 16. A telescopic device 15 for driving the follower slide 17 to rise and fall is arranged at the bottom of the sliding frame 3. Specifically, a top rotating shaft 19 is rotatably arranged at the bottom of the bottom slide 16. A bottom rotating shaft 20 is arranged on the follower slide 17. Both ends of the connecting plate 18 are connected to the top rotating shaft 19 and the bottom rotating shaft 20 respectively.

[0032] And a blocking mechanism is arranged on the lifting frame 13, and the blocking mechanism is used to block the path of the goods on the conveying roller 14 moving outward.

[0033] Embodiment 2, as Figure 1 As shown, a multi-lift reciprocating elevator proposed by the present invention, compared with the first embodiment, this embodiment introduces the structure of the power mechanism in detail.

[0034] The power mechanism includes a motor 7 and a reducer 6 arranged on the top of the fuselage shell 1, a sprocket 5 arranged on the output shaft of the reducer 6, a counterweight block 8 slidably arranged on the back of the fuselage shell 1 in the vertical direction, and a chain 4 that bypasses the sprocket 5 and connects the counterweight block 8 and the sliding frame 3 at both ends; the counterweight block 8 is used to balance the weight of the lifting part and the cargo, reduce the working load of the motor 7, and the counterweight block 8 and the fuselage shell 1 slide in cooperation with each other by means of slide rails and slide grooves.

[0035] Embodiment three, as Figure 5 As shown, a multi-lift reciprocating elevator proposed by the present invention, compared with the second embodiment, this embodiment introduces the structure of the blocking mechanism in detail.

[0036] The blocking mechanism is driven by the bottom slide 16. When the bottom slide 16 moves inward to the maximum distance, the blocking mechanism blocks the path of the goods moving outward. When the bottom slide 16 moves outward to the maximum distance, the blocking mechanism exposes the path of the goods moving outward. Specifically, it is completed by the telescopic device 15. The follower slide 17 moves downward. At this time, the connecting plate 18 forms a triangular support for the lifting frame 13 to improve stability. A plurality of limit rods 40 are arranged on the end surface of the bottom slide 16 facing the fuselage shell 1. The limit rods 40 are against the inner side of the lifting frame 13. The rear bottom slide 16 can no longer move inward, and the blocking mechanism blocks the outward movement path of the goods to prevent the goods from accidentally sliding off the lifting frame 13. Before the conveying roller 14 conveys the goods outward, the bottom slide 16 moves outward, the follower slide 17 moves upward, and the bottom slide 16 changes the state of the blocking mechanism to expose the outward movement path of the goods, and then the conveying roller 14 conveys the goods out. In order to further improve the safety protection of the goods, a protective frame 21 is set on the lifting frame 13, and the top of the protective frame 21 and the side facing the blocking mechanism are both open.

[0037] Specifically, the blocking mechanism includes a flat plate arranged on the left and right outer sides of the lifting frame 13, a door shaft 25 rotatably arranged on the flat plate, a protective door 22 arranged on the two door shafts 25, an adjusting frame 23 arranged on the bottom slide 16, and a connecting rope 24 connecting the adjusting frame 23 and the protective door 22; the bottom slide 16 moves inward to push the two protective doors 22 to rotate closer together, blocking the path for the goods to move outward to prevent the goods from accidentally slipping off the lifting frame 13; when the bottom slide 16 moves outward, the two protective doors 22 are pulled outward by the connecting rope 24 to rotate to open the moving path of the goods, so that the goods can be smoothly transported out.

[0038] Embodiment 4, as Figure 4-Figure 7 As shown, a multi-lifting reciprocating elevator proposed by the present invention, compared with the third embodiment, this embodiment introduces the structure of the docking conveying enhancement mechanism in detail.

[0039] When the lifting frame 13 and the conveying line 37 are docked to transport goods, the docking conveying reinforcement mechanism is used to form a connection structure between the two, thereby enhancing the structural strength of the lifting frame 13, which helps to improve the carrying capacity. In the process of the goods moving outward, the overall center of gravity gradually moves outward, and the greater the possible damage to the lifting frame 13, by docking the lifting frame 13 and the conveying line 37 to form a connection structure, it is equivalent to adding a support point to the lifting frame 13 with the help of the conveying line bracket 38, which greatly improves the stability and carrying capacity.

[0040] The bottom support plate 32 is arranged on the rotating column 30, and the bottom support plate 32 is located below the conveying line 37. A plurality of insertion holes 33 are arranged on the end surface of the bottom support plate 32. After the lifting frame 13 moves to be opposite to the conveying line 37, the bottom support plate 32 rotates ninety degrees until a part of it is located below the lifting frame 13. A plurality of insertion rods 36 are arranged on the bottom slide 16. The telescopic device 15 contracts and drives the follow-up slide 17 to rise, so that the bottom slide 16 moves outward, and a plurality of insertion rods 36 are inserted into the insertion holes 33. At this time, the lifting frame 13 is connected to the conveying line bracket 38 by the bottom slide 16, the insertion rod 36, the bottom support plate 32 and the rotating column 30, which greatly improves the supporting strength of the lifting frame 13 and avoids the risk of large deformation of the lifting frame 13 during cargo transportation as much as possible.

[0041] Furthermore, a side frame 26 is arranged on one side of the lifting frame 13, a rack seat 27 is slidingly arranged at the bottom of the conveying line 37, a follower frame 28 is arranged on the rack seat 27, and the side frame 26 pushes the follower frame 28 to move outward. When the lifting frame 13 is docked with the conveying line 37, the rack seat 27 is pushed to the outermost side, a rack 29 is arranged on the rack seat 27, a gear 31 is arranged on the rotating column 30, and the gear 31 is meshed with the rack 29; a fixed plate 34 is arranged at the bottom of the conveying line 37, and a spring 35 is arranged between the fixed plate 34 and the rack seat 27; in the present invention, the movement of the rack 29 drives the gear 31 and the rotating column 30 to rotate ninety degrees, thereby rotating the bottom support plate 32 to the end portion located below the lifting frame 13, and the spring 35 is used for resetting the rack seat 27. When the side frame 26 is removed, the rack seat 27 can return to the initial position to rotate the bottom support plate 32 to the bottom of the conveying line 37.

[0042] Embodiment 5, a multi-lift reciprocating elevator proposed by the present invention, compared with embodiment 4, this embodiment introduces the connection method of electrical control in detail.

[0043] In order to realize automatic control, a control system is also provided, which is connected to the motor 7, the telescopic device 15 and the power device of the conveying roller 14, and is connected to the distance measuring device 12 for data transmission. The control system controls the position of the sliding frame 3 through the real-time data transmission of the distance measuring device 12, so that the lifting frame 13 can be docked with different conveying lines 37. In order to facilitate the routing, a groove is provided on the left or right groove wall of the strip groove 2, and a drag chain line 39 is installed in the groove. The routing of the power device of the conveying roller 14 and the telescopic device 15 is located in the drag chain line 39.

[0044] In summary, when the present invention is in use, different conveyor lines 37 are used to convey goods to the lifting frame 13 or receive goods on the lifting frame 13 as needed, and a multi-lifting working mode is performed. The forward and reverse rotation of the motor 7 drives the lifting frame 13 to move up and down. When the lifting frame 13 needs to receive goods, the lifting frame 13 moves to be opposite to the conveyor line 37. During this process, the side frame 26 pushes the follower frame 28 to move outward, and finally the bottom support plate 32 rotates to the bottom of the lifting frame 13, and then the telescopic device 15 contracts to insert the insertion rod 36 into the insertion hole 33. At this time, as the bottom slide 16 moves outward, the protective door is fully opened, and then the conveyor line 37 pushes the goods to the conveying roller 14. Then, the conveying roller 14 rotates in the opposite direction to continue to convey the goods to the inside, and then the telescopic device 15 extends, the insertion rod 36 leaves the insertion hole 33, the bottom slide 16 moves inward, the connecting plate 18 tilts and supports to form a reinforced support, and the protective door 22 is completely closed. Then, as the lifting frame 13 moves away, the side frame 26 moves away, and the bottom support plate 32 is reset. When the goods on the lifting frame 13 are to be transported out, the lifting frame 13 moves to be parallel to the conveyor line 37. During this process, the side frame 26 pushes the follower frame 28 to move outward, and finally the bottom support plate 32 rotates to the bottom of the lifting frame 13, and then the telescopic device 15 contracts, the bottom slide 16 moves outward, the protective door 22 is fully opened, the insertion rod 36 is inserted into the insertion hole 33, and the conveying roller 14 rotates to transport the goods to the conveyor line 37. Then, the telescopic device 15 extends to retract the bottom slide 16, and the protective door 22 is closed. As the lifting frame 13 leaves, the bottom support plate 32 is reset.
