Description

TECHNICAL FIELD

[0001] The present application relates to the field of warehouse logistics, more particularly, it relates to a cross beam layered moving mechanism. BACKGROUND

[0002] When storing or loading goods in warehouses, stores, containers and other places or facilities, different types, sizes, and delivery locations of goods may require separate placement. In order to save space and improve space utilization, multi-layer shelves are usually used to store goods. Different sizes of goods require different sizes of storage space, but the fixed height of the layers of ordinary shelves often results in the inability to store oversized goods or the inability to store undersized goods, leading to space waste. Therefore, users want to adjust the height of the shelf according to specific needs. The invention patent with publication number CN113002921A discloses a adjustable layered shelf for a truck, which can divide the interior of the truck compartment into multiple layers to store different goods, and can adjust the size of the space as needed. However, the height adjustment of this invention is cumbersome and affects work efficiency. For example, the invention patent with publication number CN109625102A discloses a truck with an automatic layered shelf in the truck compartment, which fully utilizes the height of the truck compartment and expands the carrying capacity of the truck. However, the structure of the automatic layered mechanism in this invention is complex and occupies a large space. SUMMARY

[0003] The existing automatic layered mechanism of the shelf is either cumbersome to adjust, affecting work efficiency, or has a complex structure, affecting space utilization. To overcome these defects, the present application provides a cross beam layered moving mechanism that can more fully utilize space while more conveniently and efficiently completing shelf layering.

[0004] The technical solution of the present application is a cross beam layered moving mechanism, which includes a cross beam, a lifting track, a moving foot, and a driving device. The moving foot is slidingly connected to the lifting track and is drivingly connected to the driving device. The cross beam is connected to the moving foot. The moving foot is provided with a locking structure that can be locked with the lifting track. When the cross beam layered moving mechanism is working, the driving device drives the moving foot to lift along the lifting track, and after reaching the preset position, the locking structure is activated to reliably stop the moving foot at the position. The cross beam can lift the layer plate and other storage components to move synchronously with the moving foot, and after reaching the desired position on the lifting track, a layer of the required size is formed. The present application can flexibly adjust the layer height according to the specific needs of the storage and loading process, and the adjustment process is automatically completed, which is convenient and efficient, and can greatly improve the efficiency of storage and loading.

DETAILED DESCRIPTION

[0030] The present application will be further described in detail below with reference to specific embodiments and the accompanying drawings.

[0031] Example 1

[0032] As Figures 1 to 12The utility model discloses a kind of crossbeam layered moving mechanism, applied in container.

Foot body 301 is equipped with press block mounting groove 3012, press block 302 is installed in press block mounting groove 3012, and press block mounting groove 3012 is equipped with press block pivot shaft on the groove wall, and press block pivot shaft is connected to press block 302.Driving device 4 is motor, and driving device 4 is connected with mobile foot 3 through synchronous belt 401.The mobile support 3 is provided with a synchronous belt pressing block 304, which is fixed on the support body 301 of the mobile support 3 through screws. The synchronous belt 401 has two end heads, which are connected with the two ends of the support body 301 one by one, and each end head is pressed between the synchronous belt pressing block 304 and the support body 301. The driving device 4 is fixed on the top end of the lifting track 2, and the top end and the bottom end of the sliding groove 202 are each provided with a synchronous belt wheel 402. The output end of the driving device 4 is keyed to a driving wheel 403, and the synchronous belt 401 is connected with the driving wheel 403 and the synchronous belt wheel 402. The top of the mobile support 3 is connected with a cross beam supporting member 305, which is a pipe fitting. The end of the cross beam 1 is inserted into the cross beam supporting member 305 and is connected to the cross beam supporting member 305 through bolts.

[0033] Under normal conditions, under the action of the return torsion spring 307 of the lifting control block, the lifting control block 303 folds up, and the angle between the lifting control block 303 and the support body 301 is reduced to the minimum, raising the free end of the support body 301 so that the locking boss 3021 cannot reach the locking slot 201. Thus, the movable support leg 3 and the lifting rail 2 are in the unlocked state. When the movable support leg 3 climbs on the lifting rail 2, due to the relative movement between the lifting control block 303 and the lifting rail 2, the friction between the lifting control block 303 and the lifting rail 2... Used at the free end of the lifting control block 303, it overcomes the restoring force of the lifting control block reset torsion spring 307, causing the angle between the lifting control block 303 and the support body 301 to gradually widen, making the support body 301 closer to the surface of the lifting track 2. At this time, the locking boss 3021 can touch the locking slot 201. During the upward movement of the moving support leg 3, once it encounters the locking slot 201, under the action of the pressure block reset torsion spring 306, the locking boss 3021 sinks into the locking slot 201, and the pressure block 302 also gets closer to the lifting track 2. When the locking boss 3021 rises with the moving support leg 3 and reaches the end of the locking slot 201, the inclined surface of the locking boss 3021 is squeezed against the end of the locking slot 201. The squeezing force is decomposed into a normal force on the inclined surface, lifting the locking boss 3021 and even the pressure block 302, thus allowing the locking boss 3021 to smoothly disengage from the locking slot 201. After leaving the locking slot 201, because the width of the locking boss 3021 is greater than the opening width of the slide 202, the locking boss 3021 cannot enter the slide 202 and can only float outside the slot opening, while the moving leg 3 continues to climb smoothly and without obstruction. A position sensor is installed inside the locking slot 201, or a switch is set in the control program corresponding to the position of the locking slot 201, thus forming a stopping point. When the locking boss 3021 enters the locking slot 201, the drive device 4 receives the controller command to stop. At this time, the moving leg 3 can stop. Because the locking boss 3021 and the locking slot 201 form a locking engagement, the moving leg 3 cannot retract, thus forming a lock. The moving leg 3 and even the crossbeam 1 connected to the moving leg 3 remain in the stopped position. Outside the locking slot 201, the drive device 4 will not stop and will automatically wait to reach the nearest stopping point before receiving the stopping command. When the movable support leg 3 climbs to different heights on the lifting track 2, different floor heights can be formed. When the movable support leg 3 descends, under the control of the controller, the drive device 4 first drives the movable support leg 3 to climb slightly to ensure that the locking boss 3021 and the locking slot 201 are misaligned. Then the drive device 4 reverses and drives the movable support leg 3 to descend. During the descent, the friction between the lifting control block 303 and the lifting track 2 is combined with the elastic force of the lifting control block reset torsion spring 307, causing the lifting control block 303 to fold up and raise the free end of the support leg body 301 again, so that the locking boss 3021 is away from the locking slot 201. In this way, the movable support leg 3 and the lifting track 2 are in an unlocked state and can descend freely.

[0034] Example 2:

[0035] The cross-beam layered moving mechanism is applied to a warehouse shelf. The lifting track 2 is fixed on the shelf column. The sliding groove 202 is a dovetail groove with a small opening and a large bottom. The cross section of the leg protrusion 3011 is also trapezoidal. The take-off control block 303 in the fully retracted state forms an 85° angle with the surface of the lifting track 2. The rest is the same as example 1.
