Description

Technical Field

[0001] The present invention relates to the technical field of logistics, and particularly relates to a hoist structure of an intelligent logistics system. Background Art

[0002] With the rapid development of the national economy, automated stereoscopic warehouses are increasingly widely used in the field of modern logistics. Among them, the hoist is an important component of the automated stereoscopic warehouse. The body of the hoist is designed to match the height of the stereoscopic warehouse. In the industry, in order to ensure its stability, noise reduction and cost performance, higher requirements are put forward for its structural design. At present, the hoists used in conjunction with high-rise shelves often have poor stability and high motor costs.

[0003] For example, in the gear hoist with the publication number CN116354266A, the electric box is on one side of the bracket, and the counterweight is on the other side of the motor, making the structure less stable, and its circuit is relatively complex. The motor is on the tray, adding load to the hoist, which requires a high power of the motor and increases the cost of the motor. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a hoist structure of an intelligent logistics system, which has a simple and stable structure, low requirements for the motor power, and can reduce costs, so as to overcome the deficiencies of the prior art.

[0005] To solve the above technical problem, the technical solution of the present invention is: to provide a hoist structure of an intelligent logistics system, including a support frame, a lifting mechanism, a cage, and a counterweight. The lifting mechanism includes a driving motor, a gear commutator, and a driving wheel. Two gear commutators are symmetrically connected to both ends of the driving motor. The two gear commutators are arranged on the same axis X. Two driving wheels are symmetrically connected to both ends of the gear commutator. The two driving wheels are arranged on the same axis Y. The axis X is perpendicular to the axis Y. A driving strip is arranged on the driving wheel. The driving strip is provided with a counterweight connection end and a cage connection end. The counterweight connection end is connected to the counterweight, and the cage connection end is connected to the cage. The driving strip is in transmission connection with the driving wheel. The cage is arranged inside the support frame.

[0006] The lifting mechanism is arranged at the top end of the support frame.

[0007] The gear commutator is provided with a driving interface and two commutation interfaces. Bearings are respectively connected to the driving interface and the commutation interfaces. The driving interface is connected to a driving connecting shaft through a bearing. The other end of the driving connecting shaft is connected to the driving motor. The commutation interface is connected to a commutation connecting shaft through a bearing. The other end of the commutation connecting shaft is connected to the driving wheel.

[0008] Preferably, the driving wheel is a sprocket, the driving strip is a chain, and the sprocket is meshed with the chain.

[0009] Two first guide rails are symmetrically arranged inside the support frame. Two pairs of guide wheel assemblies paired with the first guide rails are arranged on two symmetrical sides of the cage. The guide wheel assembly includes a first guide wheel and a second guide wheel. The first guide wheel is provided with a first guide groove paired with the first guide rail. The two second guide wheels are symmetrically arranged on two sides of the first guide rail. The first guide groove and the second guide wheels are slidably connected to the first guide rail.

[0010] Two second guide rails are symmetrically arranged inside the support frame. Two pairs of guide shoes paired with the second guide rails are arranged on two sides of the counterweight. A second guide groove is arranged inside the guide shoe, and the second guide groove is slidably connected to the second guide rail.

[0011] Adopting the above technical solutions, the following beneficial effects are achieved: In the present invention, one motor is connected to two gear commutators and then to four chains, and the structure is relatively simple; In the present invention, four chains are symmetrically designed to drive the cage, and a counterweight is symmetrically designed, so the structure is relatively stable; In the present invention, the counterweight moves in the opposite direction to the cage, which can reduce the power required for the cage to move upward, thereby reducing the requirement for the motor power and reducing the cost. Through the design of one motor and counterweights on both sides, the forces on both sides of the counterweight system are evenly distributed, the counterweight system is stable, and the overlapping height of the unilateral counterweight is reduced by half due to the counterweights on both sides, which is beneficial to the stroke planning of the cage. The overall design is simple, scientific and reasonable. BRIEF DESCRIPTION OF THE DRAWINGS

The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0021] As Figures 1-6 shown, the present invention provides a hoist structure of an intelligent logistics system, including a support frame 1, a lifting mechanism 2, a cage 3, and a counterweight 4. The lifting mechanism 2 includes a driving motor 21, a gear commutator 22, and a driving wheel 223. Both ends of the driving motor 21 are connected to two gear commutators 22. The two gear commutators 22 are arranged on the same axis X. Two driving wheels 223 are symmetrically connected to both ends of the gear commutator 22. The two driving wheels 223 are arranged on the same axis Y. The axis X and the axis Y are perpendicular to each other. A driving strip 23 is arranged on the driving wheel 223. The counterweight connection end 232 in the driving strip 23 is connected to the connection head of the counterweight 4. The cage connection end 231 is connected to the cage 3 and the cage connection head 31. The driving strip 23 is in transmission connection with the driving wheel 223. The cage 3 is arranged inside the support frame 1.

[0022] Preferably, the lifting mechanism 2 is arranged at the top of the support frame 1 to facilitate the formation of a structure in which the moving directions of the cage 3 and the counterweight 4 are opposite. When the cage 3 moves upward, the counterweight 4 moves downward, and its gravity does work downward, thereby reducing the power consumption of the driving motor 21.

[0023] As Figures 2-3As shown, the gear commutator 22 is provided with a drive interface and two commutation interfaces. The drive interface and the commutation interfaces are respectively connected with a first coupling 212 and a second coupling 222. The drive interface is connected to the drive connecting shaft 211 through the first coupling 212. The other end of the drive connecting shaft 211 is connected to the drive motor 21. The commutation interface is connected to the commutation connecting shaft 221 through the second coupling 222. The other end of the commutation connecting shaft 221 is connected to the drive wheel 223.

[0024] Preferably, the drive wheel 223 is a sprocket, and the drive bar 23 is a chain. The sprocket is meshed and connected with the chain.

[0025] Preferably, a rolling bearing 213 is arranged at the top of the support frame 1. The drive connecting shaft 211 passes through the rolling bearing 213, so that the rotation of the drive connecting shaft 211 is more stable, the stress between the drive connecting shaft 211, the drive motor 21 and the gear commutator 22 is reduced, and the service lives of the drive motor 21 and the gear commutator 22 are prolonged.

[0026] Preferably, an auxiliary guide wheel 224 is arranged on the side of the drive wheel 223 away from the gear commutator 22. An auxiliary guide groove is arranged in the auxiliary guide wheel 224 and is slidably connected with the drive bar 23, so that the transmission of the drive bar 23 is smoother.

[0027] As Figure 5 shown, two pairs of guide wheel assemblies paired with the first guide rails 11 are symmetrically arranged on both sides of the cage 3 inside the support frame 1. The guide wheel assemblies include a first guide wheel 32 and a second guide wheel 33. The first guide wheel 32 is provided with a first guide groove paired with the first guide rail 11. The two second guide wheels 33 are symmetrically arranged on both sides of the first guide rail 11. The first guide groove and the second guide wheels 33 are slidably connected with the first guide rail 11.

[0028] As Figure 6 shown, two pairs of guide shoes 41 paired with the second guide rails 12 are arranged on both sides of the counterweight 4 inside the support frame 1. A second guide groove is arranged in the guide shoes 41 and is slidably connected with the second guide rail 12.

[0029] Preferably, the support frame 1 is designed as a cuboid-shaped frame, and the cage 3 is designed as a cage structure with an open upper part of the cuboid.

[0030] As Figure 1 and 3 shown, four buffer protection parts 13 are respectively arranged at the upper end and the lower end inside the support frame 1, reducing the noise generated by the collision between the cage 3 moving up and down and the support frame 1, avoiding the friction and paint loss between the cage 3 and the support frame 1, and thus prolonging the service lives of the cage 3 and the support frame 1.

[0031] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art should understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents, and improvements made without creative efforts should be included within the protection scope of the present invention.
