Description

Technical Field

[0001] This utility model belongs to the field of stacker crane technology, and in particular relates to a multi-layer cargo storage and retrieval device for stacker cranes. Background Technology

[0002] Stacker cranes are core equipment in automated warehousing and logistics systems, mainly used for the automatic storage and retrieval of goods in high-bay warehouses. Their structure typically consists of columns, a traveling mechanism, a lifting mechanism, and a fork extension mechanism. Through coordinated operation of the control system, they can achieve precise positioning and rapid handling of goods in three-dimensional space. They are characterized by high efficiency, intelligence, and reliability, and are widely used in intelligent warehousing scenarios in industries such as e-commerce, pharmaceuticals, automobile manufacturing, and cold chain logistics. They significantly improve warehouse space utilization and operational efficiency, and are an important carrier of modern logistics automation.

[0003] Most existing multi-level cargo storage and retrieval devices for stacker cranes do not have the function of rotating the stacker crane in actual use, which means that the stacker crane can only perform cargo storage and retrieval operations in one direction. This results in poor adaptability and is not conducive to the use of staff. In view of this, we propose a multi-level cargo storage and retrieval device for stacker cranes. Utility Model Content

[0004] The purpose of this invention is to provide a multi-layer cargo storage and retrieval device for stacker cranes to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a multi-layer cargo storage and retrieval device for a stacker crane, comprising:

[0006] A base plate, a connecting plate is provided on the top of the base plate, a turntable is provided on the top of the connecting plate, a first housing is fixedly connected to the top of the turntable, a first threaded rod is rotatably connected to the bottom of the inner wall of the first housing, and the first threaded rod extends through to the top of the first housing;

[0007] A first threaded sleeve is threadedly connected to the outside of a first threaded rod. The first threaded sleeve slides through to the outside of a first housing. A second housing is fixedly connected to one side of the first threaded sleeve. Two symmetrically distributed forks are provided inside the second housing. Both forks slide through to the outside of the second housing.

[0008] A rotating assembly is disposed on the top of the connecting plate and is used to drive the turntable to rotate;

[0009] A moving component is disposed inside the second housing and is used to move the two forks.

[0010] In this technical solution, the traveling wheels at the bottom of the base plate slide along the slide rail, driving the connecting plate to move. The first motor is started to drive the gear to rotate. The gear meshes with the gear ring, driving the slider and turntable to rotate, thereby changing the horizontal angle of the first housing and subsequent components. The sliding rod cooperates with the sliding block to ensure that the second housing remains stable when it rises and falls with the first threaded sleeve. This device can flexibly adjust the horizontal and angular position and accurately align with the target cargo area by moving the traveling wheels along the slide rail and rotating the turntable.

[0011] The second motor is activated to drive the first threaded rod to rotate, causing the first threaded sleeve to rise and fall, which in turn drives the second housing and sliding block to rise and fall synchronously, achieving vertical lifting and lowering of the forks. The third motor is activated to drive the second threaded rod to rotate, causing the second threaded sleeve to move along the second threaded rod, which in turn drives the two forks to extend and retract through the connecting block. Through the rotation of the first threaded rod and the drive of the second threaded rod, the forks can complete vertical lifting and horizontal extension and retraction actions, achieving accurate storage and retrieval of goods. With the above structure, goods on multi-layer shelves can be stored and retrieved. At the same time, the device can make the forks rotate horizontally, which can be used to store and retrieve goods on shelves at different angles, meeting the needs of fast and accurate storage and retrieval in high-density warehousing scenarios, and thus facilitating the use of staff.

[0012] In the above technical solution, the top of the base plate has two symmetrically distributed slide tracks, and the bottom corners of the connecting plate are fixedly installed with walking wheels. The four walking wheels are slidably installed on the bottom of the inner wall of the two slide tracks respectively.

[0013] In this technical solution, the traveling wheels at the bottom of the base plate slide along the slide rail, driving the connecting plate and the upper components to move as a whole, thereby achieving horizontal positioning of the device.

[0014] In the above technical solution, the top of the connecting plate is provided with a sliding groove, and a slider is slidably installed inside the sliding groove. The slider is fixedly connected to the turntable.

[0015] In this technical solution, the turntable is made more stable when rotating by sliding the slider inside the groove.

[0016] In the above technical solution, the rotating component further includes a gear ring, which is fixedly connected to the inner wall of the slider. A first support frame is fixedly connected to the top of the connecting plate. A first motor is fixedly installed on the top of the inner wall of the first support frame. The output shaft of the first motor is fixedly connected to the top of the connecting plate. A gear is fixedly sleeved on the output end of the first motor. The gear and the gear ring are meshed together.

[0017] In this technical solution, the first motor is started to drive the gear to rotate. The gear meshes with the gear ring, which drives the slider and turntable to rotate, thereby changing the horizontal angle of the first housing and subsequent components. Through the first support frame, the first motor will not run idle during operation.

[0018] In the above technical solution, a sliding rod is fixedly connected to the top of the connecting plate, and a sliding block is slidably installed on the outside of the sliding rod, with the sliding block being fixedly connected to the second housing.

[0019] In this technical solution, the second housing is made more stable when it moves by sliding the sliding block to the outside of the slide rod.

[0020] In the above technical solution, the moving component further includes a second threaded rod, which is rotatably installed inside the second housing. A second threaded sleeve is threadedly connected to the outside of the second threaded rod. Connecting blocks are fixedly connected to both sides of the second threaded sleeve. The two connecting blocks are fixedly connected to the two forks respectively. The two connecting blocks and the second threaded sleeve are slidably installed on the bottom of the inner wall of the second housing.

[0021] In this technical solution, the second threaded rod is driven to rotate by the third motor, the second threaded sleeve moves along the second threaded rod, and the two forks are extended and retracted through the connecting block.

[0022] In the above technical solution, a support plate is fixedly connected to one side of the second housing, a third motor is fixedly connected to the top of the support plate, the third motor is fixedly connected to the second threaded rod, a second support frame is fixedly connected to one side of the first housing, a second motor is fixedly installed on the top of the inner wall of the second support frame, and the output end of the second motor is fixedly connected to the first threaded rod.

[0023] In this technical solution, the second support frame prevents the second motor from idling during operation, and the support plate prevents the third motor from idling during operation.

[0024] The beneficial effects of this utility model are:

[0025] 1. The traveling wheels at the bottom of the base plate slide along the slide rail, driving the connecting plate to move. The first motor is started to drive the gear to rotate. The gear meshes with the gear ring, driving the slider and turntable to rotate, thereby changing the horizontal angle of the first housing and subsequent components. The sliding rod and sliding block cooperate to ensure that the second housing remains stable when it rises and falls with the first threaded sleeve. This device can flexibly adjust the horizontal and angular position and accurately align with the target cargo area by moving the traveling wheels along the slide rail and rotating the turntable.

[0026] 2. The second motor is started to drive the first threaded rod to rotate, causing the first threaded sleeve to rise and fall, which in turn drives the second housing and sliding block to rise and fall synchronously, realizing the vertical lifting and lowering of the forks. The third motor is started to drive the second threaded rod to rotate, causing the second threaded sleeve to move along the second threaded rod, which drives the two forks to extend and retract through the connecting block. Through the rotation of the first threaded rod and the drive of the second threaded rod, the forks can complete vertical lifting and horizontal extension and retraction actions, realizing accurate storage and retrieval of goods. With the above structure, goods on multi-layer shelves can be stored and retrieved. At the same time, this device can make the forks rotate horizontally, which can store and retrieve goods on shelves at different angles, meeting the needs of fast and accurate storage and retrieval in high-density warehousing scenarios, and thus facilitating the use of staff.
