Specific embodiments

[0030] The following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustration and explanation of the present utility model, and are not intended to limit the present utility model.

[0031] In this embodiment, the inner side of the shelf 1, i.e., the side where the elevator is located, is defined as the inner side.

[0032] As Figure 1 shown, the present utility model provides a single-bin elevator, which is embedded in the shelf 1 and occupies a bin space, and the elevator reciprocates up and down in the shelf 1. The elevator includes a lifting platform assembly 21, a driving assembly 22, a guiding component 23 and a safety component 24 that can move up and down in the single-bin shelf 1. The lifting platform assembly 21 is connected to the driving assembly 22, and the driving assembly 22 drives the lifting platform assembly 21 to move in the shelf 1 through the guiding component 23. A top frame 3 made of profile welding is fixed at the top of the shelf 1.

[0033] The shelf 1 includes four vertically arranged column units 11, and the planes where adjacent column units 11 are located are perpendicular to each other. A number of connection holes are reserved on three mounting surfaces of the column unit 11, and the connection holes are arranged in an array for flexibly installing required components. A number of bracket cross beams 12 and T-rail support frames 13 are arranged at intervals on different surfaces of the shelf 1. Specifically, the bracket cross beams 12 and the T-rail support frames 13 are horizontally arranged on the surfaces where two adjacent column units 11 are located, and both the bracket cross beams 12 and the T-rail support frames 13 are fixed to the column unit 11 through the connection holes. The shelf 1 can also be connected to other shelves to form a whole, greatly enhancing the strength of the entire single-warehouse embedded elevator.

[0034] As Figure 2 shown, the lifting platform assembly 21 includes a lifting platform frame body, a platform bottom mounting plate 214, a pair of platform first working guide rails 211 and a pair of platform second working guide rails 212. The lifting platform frame body includes a bottom frame arranged in a rectangle, and the bottom frame is welded by front, rear profiles and left, right profiles. The left and right profiles are welded on the front and rear profiles, and the two are arranged at different heights; a side frame 213 is arranged above the left and right profiles of the bottom frame, and the side frame 213 is also in a rectangle. The whole lifting platform frame body presents a concave shape, is welded by profiles, has high overall strength, meets the use requirements, and is light in weight, greatly reducing the load requirements of the drive system. The platform first working guide rails 211 and the platform second working guide rails 212 are arranged in pairs on the front and rear profiles of the bottom frame and inside the two side frames 213. Among them, the platform first working guide rail 211 is located outside the platform second working guide rail 212, and the platform first working guide rail 211 is higher than the platform second working guide rail 212. The platform first working guide rail 211 serves as the track for the shuttle car to travel, and the platform second working guide rail 212 serves as the placement position for the pallet goods.

[0035] (6) The drive assembly 22 includes a motor 221, a speed reducer 222, and a gear 223. The motor 221 is a servo motor, and it is mounted in pairs under the bottom mounting plate 214 of the platform through a drive assembly mounting bracket 225. Both the motor 221 and the speed reducer 222 are provided in two numbers, and the two speed reducers 222 are diagonally arranged on the outer sides of the two motors 221. The gear 223 is fixedly connected to the speed reducer 222. One end of the bottom mounting plate 214 of the platform is arranged under the left and right profiles of the bottom frame, and the other end is arranged under the second working guide rail 212 of the platform on the same side as the left and right profiles of the bottom frame. The bottom mounting plate 214 of the platform is provided in two numbers. The motor 221 and the speed reducer 222 are built into the lifting platform assembly 21, and the advantage of this is that the structure of the lifting platform assembly 21 is compact and more practical. In the prior art, there are also lifting platforms with the motor placed at the bottom and lifting platforms with two servo motors placed on the top. For the former, the variable-frequency motor is large in size and occupies a large amount of space at the bottom; for the latter, the two servo motors are placed on the top of the lifting platform. For the same size of goods, the size of this lifting platform needs to be increased in width and length, which requires additional space. The bottom mounting plate 214 of the platform is directly fixed to the second working guide rail 212 of the platform, saving the height occupied by the front and rear profiles of the bottom frame. The bottom mounting plate 214 of the platform and the lowest surface of the bottom frame form a high-low structure, reducing the height of the first layer of goods placement positions on the shelf 1 and increasing the storage density. At the same time, the lifting platform frame of the present utility model adopts a high-low layout of the front, rear, left, and right frames, removing the restrictions on the bottom space and the increase in width and length of the lifting platform, and having good practicability and popularization value.

[0036] As Figure 3 , 4 shown, the guiding assembly 23 includes a T-shaped guide rail 231, which is vertically arranged inside the T-rail support frame 13. A rack 224 is vertically arranged on the T-shaped guide rail 231. When the motor 221 starts and the speed reducer 222 operates, the output end of the motor 221 is connected to the gear 223, and the gear 223 meshes with the rack 224 to drive the lifting platform assembly 21 to move up and down reciprocally. The guiding assembly 23 further includes guiding angle steels 232, a first guiding wheel 233, and a second guiding wheel 234. The guiding angle steels 232 are also vertically arranged inside the T-rail support frame 13 and are vertically parallel to the T-shaped guide rail 231. Both the T-shaped guide rail 231 and the guiding angle steels 232 are provided in pairs and are diagonally arranged with respect to the central axis of the lifting platform assembly 21. The advantage of this is that both the first guiding wheel 233 and the second guiding wheel 234 are arranged on both sides of the lifting platform assembly 21, with uniform force and good synchronization performance.

[0037] The first guide wheels 233 are arranged on the upper surfaces of the left and right profiles of the bottom frame and the two side frames 213. The first guide wheels 233 arranged on the upper surfaces of the bottom frame and the side frames 213 are vertically aligned, and the first guide wheels 233 are diagonally arranged relative to the central axis of the lifting platform assembly 21; the second guide wheels 234 are arranged on the outer surfaces of the left and right profiles of the bottom frame and the transverse profiles of the two side frames 213, and are arranged in two groups on the left and right. Each group of the second guide wheels 234 is vertically aligned, and the second guide wheels 234 are also diagonally arranged relative to the central axis of the lifting platform assembly 21. As Figure 2 shown, mounting holes for the first guide wheels 233 and the second guide wheels 234 are reserved on the lifting platform assembly 21. The first guide wheels 233 are in direct contact with the front of the T-shaped guide rail 231, and the two groups on the left and right of the second guide wheels 234 are respectively in contact with the non-rack-mounted sides of the T-shaped guide rail 231 and the inner sides of the guide angle steels 232.

[0038] As Figure 5 shown, the safety assembly 24 includes a buffer 241, a groove-shaped photoelectric sensor 242, and an electric stopper 243. The buffer 241 is a polyurethane buffer, which is arranged below the lifting platform assembly 21 and below the top frame 3. Its function is to ensure that the drive assembly 22 and the lifting platform assembly 21 do not directly collide with the ground and the top frame 3 when the lifting platform assembly 21 runs up and down beyond the stroke limit. The groove-shaped photoelectric sensors 242 are arranged at the four corners above the lifting platform assembly 21. When the lifting platform assembly 21 runs to the height of the first layer of shelves, the groove-shaped photoelectric sensors 242 at the four corners are automatically triggered. When all the groove-shaped photoelectric sensors 242 at the four corners are triggered, it means that the lifting platform assembly 21 is in a horizontal position; when not all the groove-shaped photoelectric sensors 242 at the four corners are triggered, it means that the carrying platform of the lifting platform assembly 21 is not horizontal and requires personnel to intervene to solve. The electric stopper 243 is arranged below the lifting platform assembly 21. When the four-way vehicle is inside the lifting platform assembly 21, the electric stopper 243 rises and is stuck in the card slot of the four-way vehicle to limit the position of the four-way vehicle and prevent the four-way vehicle from running away when the lifting platform assembly 21 runs up and down, protecting the safety of the equipment and personnel.
