1, the composition of the dense cabinet frame
The dense cabinet is mainly composed of track, base, column (plate), shelves, hanging boards, side leaning boards, back boards, top boards, dust boards, guard boards, door boards, transmission mechanism, anti-tipping, anti-vibration, dust, rodent-proof, braking, buffering, transmission, sealing device cabinet into:
(1) The track includes the ground rail and the guide rail.
(2) Shelf includes columns, hanging boards, shelves, separator bars, dustproof boards.
Pillar: support the entire shelf of vertical columns;
Hanging plate: placed between the shelf and the shelf, play a role in supporting the fixed;
Shelf: the storage of archival materials on a flat board;
Divider bar: used to separate the middle of the information stored on both sides, to prevent confusion;
Dust board: placed on the top of the shelf, mainly used to prevent dust.
(3) Transmission device includes: chain, gear, hand disk, bearing, roller, lock.
The diameter of spindle and bearing is φ20mm, 45# steel five factory high quality manganese steel material GB3882-87, Z390504 outer spherical bearing with seat, short shaft pipe sleeve connection drive, with reliable center straightness, the frame moves smoothly, lightweight, natural.
(4) chassis: mainly used to support the base of the frame.
(5) sealing device: prevent the intensive cabinet from damage due to impact when closing the shelf, and at the same time, it can also reduce the noise generated by the impact when opening and closing the shelf, and play the role of anti-collision, dust-proof, moisture-proof, noise-proof, rodent-proof;
(6) panels: including the inner panel, outer panel, and the door panel
(7) top plate: the top of the intensive cabinet shelf, the top of each cabinet is equipped with a dustproof device to prevent the dust from falling into the cabinet. Dustproof device can prevent dust from falling into the cabinet
(8)Anti-fall device of cabinet top and bottom frame: each group of active single-sided cabinet top is equipped with anti-fall device.
(9) Anti-tipping device: placed on the top of the guide rail, used to stabilize the dense cabinet and prevent it from tipping over.
2, transmission
Transmission mechanism: the general use of mechanical full-automatic off-hook drive. Product parts, combinations of parts to maintain interchangeability.
Transmission components:
① Rocker: the use of rocking disk-type rocker type, hand-operated installation of brake control, smooth operation.
② Shaft: 45# steel, machining accuracy 3, 2, tempered by heat treatment HB220 ~ 290.
③ Sprocket: 45# steel, quoted GB1244-84 (3R tooth type) standard, forging processing molding, tempering stress relief, processing of the car, rolling teeth, inserting the key groove, dehairing the teeth, teeth frequency quenching HRC60-62.
④ Bearings: 204 bearings are used. ④ Bearing: 204 bearings are used.
⑤ Chain: 12, 7-pitch ball chain (Jiangnan Chain Co., Ltd.) is used. According to GB1135-89 thickness of chain 1/2" international made.
⑥ Roller: ZG35, cast steel, processed and molded.
⑦ Track: 45# steel, cold rolled square steel.
⑧ Connection tube: adopts seamless tube
3, the electrical control composition and display:
The electrical control part is made of advanced arm chip as processor, with fast processing speed and timely response. The communication mechanism adopts the CAN communication mechanism used in automobiles to ensure stable and reliable communication. There are corresponding electrical protection lines on each control board to ensure the electrical safety of each control board and dense cabinet.
There is a control board on the front panel of each column, which is used to display the status of each column, and there are corresponding keys on the control board to control the operation of the dense cabinet. There is also a main control board on the front panel of the fixed column, and the difference between the main control board and the column control board is that: the column control board is used to control the display of the status of the column, while the main control board displays the status of the whole intensive cabinet, and the main control board has the display of the time and temperature. (The main control board of the intelligent intensive cabinet has two kinds of display modes, LCD and touch screen, which are optional. The electric intensive cabinet does not have this part).
The columns also have horizontal and vertical rows of indicator lights, which are used to indicate the specific location of the files. (Electric intensive cabinet does not have this function)
4, handheld and host computer:
Handheld and host computer is equipped with file management software, you can respectively control the intensive cabinet and file management. And it can display the specific location of the designated files.
