Description

Technical Field

[0001] This invention relates to the field of mobile shelving technology, and more specifically, to a double-layer mobile shelving system. Background Technology

[0002] Mobile shelving (also known as mobile cabinets) is mainly used for storing archives, securities, and other documents. It offers advantages such as security, high space utilization, and convenient access. To facilitate management and save space, many existing mobile shelving units are designed to be movable. To increase the number of archives that can be stored in a mobile shelving unit, the shelving structure must be heightened to provide more storage layers and space. Consequently, to accommodate the increased height, auxiliary facilities such as access platforms and ladders must be introduced.

[0003] Patent CN204751207U discloses a mobile shelving unit with a built-in ladder. Normally, each mobile shelving unit comes with a ladder stored in a narrow, vertical storage space on one side of the unit. When in use, the ladder can be pulled out of the storage space, rotated, and suspended from a sliding rod at the top of the unit for easy placement at any desired location. The ladder can also be extended to create an angle with the ground for easier climbing. After use, the ladder can be retracted and slid along the sliding rod into the storage space on the side of the unit, then rotated and inserted sideways into the storage space.

[0004] While the aforementioned mobile shelving units are advantageous for storing more files and documents, the height of these units makes them prone to tipping over and unstable during movement. Summary of the Invention

[0005] The main technical problem solved by this invention is to provide a double-layer mobile shelving unit. The heightened mobile shelving unit can store more files and documents while making them easier to access or retrieve. When moving the mobile shelving unit, it can also effectively prevent it from tipping over and improve its stability during movement.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a double-layer mobile shelving unit, comprising two fixed columns of mobile shelving and multiple movable columns of mobile shelving, wherein the multiple movable columns of mobile shelving are movably arranged between the two fixed columns of mobile shelving. The bottom of each movable column of mobile shelving is provided with a moving mechanism for moving the movable column of mobile shelving. Multiple connecting beams are also provided between the two fixed columns of mobile shelving. The two ends of each connecting beam are respectively connected to the middle of the two fixed columns of mobile shelving. The connecting beams pass through the movable columns of mobile shelving. The movable columns of mobile shelving are movably connected to the connecting beams. A first step for people to walk on is laid on the multiple connecting beams. The first step passes through the movable columns of mobile shelving. A staircase structure for people to go from the ground to the first step is provided on the outside of the two fixed columns of mobile shelving.

[0007] The beneficial effects of this invention are as follows: the two ends of the connecting beam are respectively set on the two fixed columns of the mobile shelving, so that the connecting beam is stable. The connecting beam passes through the mobile shelving moving column and is movably connected to the mobile shelving moving column, which can effectively prevent the mobile shelving moving column from tipping over and improve the moving stability of the mobile shelving moving column. The first step is laid on multiple connecting beams, which can be used for people to walk. In addition, by setting up a staircase structure, it is convenient for people to quickly go up to the first step, which is convenient for them to look up or take out the data files at the top of the mobile shelving.

[0008] Preferably, the mobile shelving unit includes multiple supporting columns, and the sidewall of the connecting beam is provided with a track groove extending to both ends of the connecting beam. The middle of each supporting column is provided with a connecting part for moving and engaging with the track groove. By adopting this structure, the connecting part on the supporting column can move within the track groove on the connecting beam, thereby providing effective support for the mobile shelving unit during movement and preventing it from tipping over.

[0009] Preferably, the connecting part includes a slider disposed on the supporting column, the slider being embedded in and slidably connected to the track groove. Through the stable sliding connection between the slider and the track groove, the connecting beam provides sliding support for the mobile shelving unit, improving the movement stability of the mobile shelving unit.

[0010] Preferably, the connecting part includes a connecting shaft disposed on the supporting column, and a roller is rotatably disposed at the end of the connecting shaft away from the supporting column. The roller is rolled within the track groove. By rolling the roller within the track groove, the connecting beam provides movable support for the mobile shelving unit, and the rolling arrangement reduces friction, ensuring smooth movement of the mobile shelving unit and improving movement efficiency.

[0011] Preferably, the staircase structure includes a staircase frame, which is detachably connected to the mobile shelving unit. A second step is laid on the staircase frame for personnel to walk on, and the horizontal height of the second step is the same as that of the first step. A stair rail connects to the second step. By adopting this structure, personnel can ascend the stair rail to the second step and then enter the first step from the second step, facilitating the transfer of personnel from the ground to the first step and enabling quick access to information at higher levels of the mobile shelving unit.

[0012] Preferably, the second tread and staircase are equipped with guardrails. By adopting the above structure, personnel are prevented from falling from the second tread or staircase, thus improving safety.

[0013] Preferably, a moving track is provided between the two fixed columns of mobile shelving units for the movement of a mobile shelving unit. The two ends of the moving track are respectively located at the bottom of the two fixed columns. The moving mechanism includes a moving frame, within which a driving shaft and a driven shaft are rotatably mounted. A rolling wheel is fixed on the driven shaft, and the rolling wheel rolls on the moving track. The driving shaft is connected to the driven shaft via a first transmission component. The mobile shelving unit is equipped with a drive assembly for driving the driving shaft to rotate. With this structure, in use, the drive assembly drives the driving shaft to rotate, which in turn drives the driven shaft to rotate via the first transmission component. The driven shaft then drives the rolling wheel to roll on the moving track, enabling the mobile shelving unit to move between the two fixed columns. The structural connection is stable, improving the movement stability of the mobile shelving unit.

[0014] Preferably, the drive assembly includes a hand crank mounted on the side wall of the mobile shelving unit, the hand crank being connected to the drive shaft via a second transmission component. With this structure, rotating the hand crank drives the drive shaft to rotate via the second transmission component, effectively moving the mobile shelving unit and providing convenient operation.

[0015] Preferably, the driving assembly includes a drive motor disposed at the bottom of the mobile shelving unit's moving column. The drive motor is connected to the active rotating shaft via a third transmission component. A control instrument is disposed on the side wall of the fixed column of the mobile shelving unit, and the control instrument is electrically connected to the drive motor. By adopting the above structure, the control instrument controls the operation of the drive motor, which in turn drives the active rotating shaft to rotate via the third transmission component, effectively moving the mobile shelving unit's moving column. This provides convenient driving while improving the moving accuracy of the mobile shelving unit's moving column. Attached Figure Description
