Description

Technical Field

[0001] The utility model belongs to the field of containers, and particularly relates to an anti-tilting structure for a cargo basket. Background Art

[0002] As a commonly used storage tool, containers are often used in various storage environments, such as express storage, warehousing and other storage scenarios. To improve the storage effect of the container, usually by increasing the height of the container, the capacity of the container can be increased without changing the floor area. However, it is inconvenient to pick up and place the goods stored on the upper layer of the container. To improve the convenience of the container, there are containers with a circulating cargo basket on the market. The cargo basket that circulates inside the container transports the goods on the upper layer to the bottom layer, facilitating the access of goods.

[0003] In the prior art, as shown in the patent document with the publication number CN215158012U, a circulating storage rack for convenient access of goods is disclosed, which reduces the difficulty of picking up and placing goods through a circulating hanging basket. However, this storage rack still has certain defects. On the one hand, the hanging basket on this storage rack is rotatably connected to the connecting slide plate, and the self-weight method is used to prevent the hanging basket from tilting during the front-back position change. However, this anti-tilting method will cause the hanging basket to shake, with poor stability and certain noise; on the other hand, this storage rack hoists the cargo basket through an endless chain, and the endless chain is formed by a plurality of chain links connected end to end in sequence. To ensure the smooth rotation of each chain link, there will be gaps between each chain link, and there is a risk that the endless chain will shift left and right, causing the connecting slide plate to come off. Summary of the Invention

[0004] Aiming at the problems in the prior art, the utility model proposes an anti-tilting structure for a cargo basket, which drives a crank through a balance guide rail to make the cargo basket rotate in the opposite direction of the tilting direction of the cargo basket when changing positions front and back, and then drives the cargo basket to rotate in the opposite direction of the tilting direction to offset the tilting angle of the cargo basket and prevent the cargo basket from tilting when changing positions front and back.

[0005] The utility model is realized as follows: An anti-tilting structure for a cargo basket is arranged inside a vertical container and includes a transmission unit that rotates intermittently in a cycle. A plurality of evenly arranged adjustment crank assemblies are provided on the transmission unit. The adjustment crank assembly includes a rotating shaft, a crank, a first connecting rod, and a second connecting rod; one end of the first connecting rod and the second connecting rod is rotatably connected to the rotating shaft, and the other end is connected to the transmission unit; one end of the crank is pivotally connected to the rotating shaft, and the other end is provided with a first roller; an installation flange is further provided on the rotating shaft, and the installation flange is connected to the cargo basket; the transmission unit transports the cargo baskets on the upper layer in the vertical container to the bottom layer in sequence through intermittent cyclic rotation, facilitating the access of goods; the adjustment crank assembly is used to connect the transmission unit and the cargo basket.

[0006] The adjusting crank assembly further includes a plurality of wear-resistant washers disposed between adjacent cranks, the first connecting rod, and the second connecting rod. The wear-resistant washers are used to reduce the frictional loss between the adjacent cranks, the first connecting rod, and the second connecting rod, extend the service life of the cranks, the first connecting rod, and the second connecting rod, and also reduce the noise generated by friction between the cranks, the first connecting rod, and the second connecting rod, reducing sound pollution.

[0007] It further includes a balance guide rail adapted to the conveying unit. A semi-closed first guide groove is provided on the balance guide rail. An opening is provided on one side of the first guide groove facing the first roller. The opening is provided with a rib extending from both sides towards the middle. A relief groove with a groove width smaller than the diameter of the first roller is formed between the ribs. The ribs are used to prevent the first roller from disengaging from the first guide groove, improving the reliability of the first roller. The first roller extends into the first guide groove and rolls in the first guide groove; during the rolling process of the first roller in the first guide groove, the extending direction of the crank maintains a fixed angle with the horizontal plane. When the conveying unit moves, it drives the adjusting crank assembly to move. At the same time, the first roller rolls in the first guide groove; when the basket is reversed front and back, the first guide groove drives the crank to rotate relative to the conveying unit, and then drives the basket to rotate relative to the conveying unit to offset the tilt angle when the basket is reversed front and back, so that the basket maintains a fixed angle with the horizontal plane and prevents the basket from tilting when it is reversed front and back.

[0008] Preferably, both the balance guide rail and the conveying unit are formed by connecting a plurality of straight line segments and arc segments end to end, and the straight line segments and arc segments of the balance guide rail correspond to the straight line segments and arc segments of the conveying unit. When the basket moves vertically, the first roller rolls in the straight line segment of the balance guide rail, and the straight line segment of the balance guide rail guides the first roller to prevent the first roller from driving the crank to rotate, thereby causing the basket to tilt.

[0009] Specifically, the balance guide rail and the conveying unit are eccentrically arranged. The movement track of the basket in the vertical cabinet is circular. The eccentric arrangement of the balance guide rail and the conveying unit enables the crank to rotate from the outside of the rotating shaft to the inside or from the inside of the rotating shaft to the outside when the basket is reversed front and back, so that the movement track of the crank relative to the rotating shaft forms a circle. Thus, when the basket is reversed front and back above or below the vertical cabinet, the tilt angle of the basket can be offset by the rotation of the crank, improving the reliability of the anti-tilt structure.

[0010] Preferably, a first anti-rotation portion is provided at the connection between the rotating shaft and the crank, and the crank is provided with a second anti-rotation portion adapted to the first anti-rotation portion, with the first anti-rotation portion and the second anti-rotation portion being engaged. The first and second anti-rotation portions are used to prevent the rotating shaft and the crank from rotating synchronously, thereby allowing the crank to drive the cargo basket to rotate, thereby improving the reliability of the crank.

[0011] Preferably, the machine further comprises a vertical guide rail adapted to the transmission unit, the adjusting crank assembly being slidably connected to the vertical guide rail. The vertical guide rail is used to guide the adjusting crank assembly in vertical motion, thereby preventing the adjusting crank assembly from shaking during vertical motion and improving the stability of the adjusting crank assembly.

[0012] Specifically, the vertical guide rail is provided with a second guide groove, and the ends of the first and second connecting rods connected to the transmission unit are each provided with a second roller, which slides in the second guide groove from top to bottom or from bottom to top. The rolling connection between the second roller and the second guide groove facilitates smoother movement between the adjusting crank assembly and the vertical guide rail.

[0013] Preferably, the outer and / or inner sides of the balancing guide rail are provided with an entrance and exit for the first roller to enter and exit the first guide groove, and the entrance and exit connect the first guide groove with the outside world. When the width of the avoidance groove is smaller than the diameter of the first roller, it is difficult for the first roller to pass through the avoidance groove and enter the first guide groove. The entrance and exit are used to allow the first roller to easily enter and exit the first guide groove, thereby improving the convenience of installing the first roller.

[0014] Specifically, a sealing plate is further provided at the entrance and exit, and the sealing plate completely covers the entrance and exit. When all the first rollers pass through the entrance and exit and enter the first guide groove, the entrance and exit are blocked by the sealing plate to prevent the first rollers from escaping from the entrance and exit during movement, thereby improving the reliability of the first guide groove.

[0015] Preferably, a sensor corresponding to the adjustment crank assembly is provided within the vertical container, with the sensing end of the sensor facing the adjustment crank assembly. One of the adjustment crank assemblies is provided with a sensing portion adapted to the sensor, and when the cargo basket reaches the sensor position, the sensing portion triggers the corresponding sensor. The sensing portion is used to detect whether the cargo basket is in place. When cargo baskets in different positions move to the cargo access position, they need to pass through different numbers of sensors. Each time the cargo basket passes a position, the sensing portion triggers a different sensor. The position of the cargo basket is determined by the cumulative number of triggering of multiple sensors, thereby improving the accuracy of cargo basket transportation.

[0016] Preferably, the first link and the second link gradually decrease from the end connected to the rotating shaft to the end connected to the conveying unit, which is used to reduce the weights of the first link and the second link while ensuring the connection strength between the first link and the second link, thereby reducing the overall weight of the anti-tilting structure and facilitating the installation of the anti-tilting structure on the cabinet.

[0017] Advantages of the present utility model:

[0018] The present utility model provides an anti-tilting structure for a cargo basket. On the one hand, when the balance guide rail drives the crank to change positions back and forth in the cargo basket, the crank rotates in the opposite direction to the tilting direction of the cargo basket relative to the conveying unit, thereby driving the cargo basket to rotate in the opposite direction to the tilting direction relative to the conveying unit to offset the tilting angle of the cargo basket, so that the cargo basket maintains a fixed angle with the horizontal plane, preventing the cargo basket from tilting when changing positions back and forth, and thus enabling the cargo basket to always maintain a stable horizontal posture during lifting and changing positions back and forth; and the retaining edge provided at the opening of the first guide groove prevents the first roller from disengaging from the first guide groove, improving the reliability of the first roller. On the other hand, wear-resistant gaskets provided between adjacent cranks, first links and second links also extend the service lives of the cranks, first links and second links and reduce the noise generated by friction, reducing noise pollution.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] As Figures 1-8 shown, an anti-tilting structure of a basket is provided inside a vertical cabinet, including a transfer unit 1 that rotates intermittently in a cycle,

[0031] In this embodiment, the transfer unit 1 is a chain;

[0032] A plurality of evenly arranged adjusting crank assemblies 2 are provided on the transfer unit 1,

[0033] In this embodiment, an inductor corresponding to the adjusting crank assembly 2 is provided inside the vertical cabinet, and the sensing end of the inductor faces the adjusting crank assembly 2; an inductive part 26 adapted to the inductor is provided on one of the adjusting crank assemblies 2. When the basket reaches the position of the inductor, the inductive part 26 triggers the corresponding inductor. The inductive part 26 is used to detect whether the basket is in place. When baskets at different positions move to the storage and retrieval positions of goods, they need to pass through different numbers of inductors, and each time the basket passes through a position, the inductive part 26 will trigger a different inductor once. The position of the basket is determined by the cumulative trigger times of the multiple inductors, improving the accuracy of basket transportation.

[0034] The adjusting crank assembly 2 includes a rotating shaft 21, a crank 22, a first connecting rod 23 and a second connecting rod 24; one ends of the first connecting rod 23 and the second connecting rod 24 are rotatably pivoted to the rotating shaft 21, and the other ends are connected to the transfer unit 1; one end of the crank 22 is connected to the rotating shaft 21, and the other end is provided with a first roller 221; a mounting flange 27 is further provided on the rotating shaft 21, and the mounting flange 27 is connected to the basket; the transfer unit 1 transports the baskets at high levels inside the vertical cabinet to the bottom layer in turn through intermittent cyclic rotation, facilitating the storage and retrieval of goods; the adjusting crank assembly 2 is used to connect the transfer unit 1 and the basket.

[0035] In this embodiment, the first connecting rod 23 and the second connecting rod 24 gradually decrease from the end connected to the rotating shaft 21 to the end connected to the conveying unit 1, which is used to reduce the weights of the first connecting rod 23 and the second connecting rod 24 while ensuring the connection strength between the first connecting rod 23 and the second connecting rod 24, and further reduce the overall weight of the anti-tilting structure, facilitating the installation of the anti-tilting structure on the storage cabinet.

[0036] In this embodiment, a first anti-rotation portion 211 is provided at the connection between the rotating shaft 21 and the crank 22, the crank 22 is provided with a second anti-rotation portion 222 adapted to the first anti-rotation portion 211, and the first anti-rotation portion 211 is snap-connected to the second anti-rotation portion 222. The first anti-rotation portion 211 and the second anti-rotation portion 222 are used to prevent the rotating shaft 21 and the crank 22 from rotating synchronously, so that the crank 22 drives the basket to rotate, improving the reliability of the crank 22.

[0037] In this embodiment, a vertical guide rail 4 adapted to the conveying unit 1 is further included, and the adjusting crank assembly 2 is slidably connected to the vertical guide rail 4. The vertical guide rail 4 is used to guide the adjusting crank assembly 2 moving vertically, preventing the adjusting crank assembly 2 from jittering during vertical movement and improving the stability of the adjusting crank assembly 2.

[0038] Specifically, a second guide groove is provided on the vertical guide rail 4, and second rollers 25 are provided at the ends of the first connecting rod 23 and the second connecting rod 24 connected to the conveying unit 1, and the rollers slide in the second guide groove from top to bottom or from bottom to top. By the rolling connection between the second rollers 25 and the second guide groove, the movement between the adjusting crank assembly 2 and the vertical guide rail 4 is smoother.

[0039] A balance guide rail 3 adapted to the conveying unit 1 is further included, and a semi-closed first guide groove 31 is further provided on the balance guide rail 3. The first roller 221 extends into the first guide groove 31 and rolls in the first guide groove 31; during the rolling process of the first roller 221 in the first guide groove 31, the extending direction of the crank 22 maintains a fixed angle with the horizontal plane. When the conveying unit 1 moves, it drives the adjusting crank assembly 2 to move. At the same time, the first roller 221 rolls in the first guide groove 31; when the basket is replaced front and back, the first guide groove 31 drives the crank 22 to rotate relative to the conveying unit 1, and further drives the basket to rotate relative to the conveying unit 1 to offset the tilting angle when the basket is replaced front and back, so that the basket maintains a fixed angle with the horizontal plane and prevents the basket from tilting when it is replaced front and back.

[0040] In this embodiment, both the balance guide rail 3 and the conveying unit 1 are formed by connecting multiple straight segments and arc segments end to end, and the straight segments and arc segments of the balance guide rail 3 correspond to the straight segments and arc segments of the conveying unit 1. When the basket moves vertically, the first roller 221 rolls within the straight segment of the balance guide rail 3, and the straight segment of the balance guide rail 3 guides the first roller 221 to prevent the first roller 221 from driving the crank 22 to rotate, thereby causing the basket to tilt.

[0041] Specifically, the balance guide rail 3 and the conveying unit 1 are eccentrically arranged. The movement trajectory of the basket in the vertical cabinet is circular. The eccentric arrangement of the balance guide rail 3 and the conveying unit 1 enables the crank 22 to rotate from the outside of the rotating shaft 21 to the inside or from the inside of the rotating shaft 21 to the outside when the basket changes positions front and back, so that the movement trajectory of the crank 22 relative to the rotating shaft 21 forms a circle. Thus, when the basket changes positions front and back above or below the vertical cabinet, the rotation of the crank 22 can offset the tilt angle of the basket, improving the reliability of the anti-tilt structure.

[0042] In this embodiment, an opening is provided on the side of the first guide groove 31 facing the first roller 221. The opening is provided with retaining edges 32 extending from both sides towards the middle, and an avoidance groove 33 with a groove width smaller than the diameter of the first roller 221 is formed between the retaining edges 32. The retaining edges 32 are used to prevent the first roller 221 from disengaging from the first guide groove 31, improving the reliability of the first roller 221.

[0043] Specifically, an entrance and exit for the first roller 221 to enter and exit the first guide groove 31 is provided on the outer peripheral side of the balance guide rail 3, and the entrance and exit communicates the first guide groove 31 with the outside. When the width of the avoidance groove 33 is smaller than the diameter of the first roller 221, it is difficult for the first roller 221 to enter the first guide groove 31 through the avoidance groove 33. The entrance and exit is used to enable the first roller 221 to easily enter and exit the first guide groove 31, improving the convenience of installing the first roller 221.

[0044] Specifically, a sealing plate 34 is further provided at the entrance and exit, and the sealing plate 34 completely covers the entrance and exit. After all the first rollers 221 enter the first guide groove 31 through the entrance and exit, the entrance and exit is blocked by the sealing plate 34 to prevent the first roller 221 from disengaging from the entrance and exit during movement, improving the reliability of the first guide groove 31.

[0045] The adjusting crank assembly 2 further includes a plurality of wear-resistant gaskets 28, and the wear-resistant gaskets 28 are disposed between adjacent cranks 22, the first connecting rod 23 and the second connecting rod 24. The wear-resistant gaskets 28 are used to reduce the frictional loss between the adjacent cranks 22, the first connecting rod 23 and the second connecting rod 24, extend the service life of the cranks 22, the first connecting rod 23 and the second connecting rod 24, and can also reduce the noise generated by friction between the cranks 22, the first connecting rod 23 and the second connecting rod 24, and reduce the sound pollution.
