[0049] Before using the telescopic pipe rack, first conduct a comprehensive inspection of the rack to ensure that all types of equipment are normal and that each cable and feeder connection is stable. For the convenience of expression, we name the storage position at the front end as the front storage position, and the storage position at the rear end as the rear storage position, and then name them from bottom to top: the first front storage position, the second front storage position, the first rear storage position, the second rear storage position, and so on. The staff enters the name, specification and other data information of the preset types of pipes that need to be stored in the telescopic pipe rack into the control tablet 14 in advance. According to the principle that only one specification of pipe can be stored in one storage position, the first front storage position stores a stainless steel pipe with a length of 6000 mm, a wall thickness of 1.5 mm, and an outer diameter of 12 mm in the control tablet 14, and the second rear storage position stores a polyethylene pipe with a length of 6500 mm, a wall thickness of 0.4 mm, and an outer diameter of 20 mm, and so on. The staff inserts the prepared labels into the corresponding identification insertion area 7, and can query them in the control tablet 14 at the same time;

[0050] In the case of no electricity or power outage, two stainless steel pipes with a length of 6000mm, a wall thickness of 1.5mm and an outer diameter of 12mm need to be stored. The staff will use the hand crank handle 11 according to the label content in the identification insertion area 7, or query from the control tablet 14, and rotate the folded rotating handle inward 90°. The rotating handle is opened. The internal shape of the sleeve is a hexagonal prism that matches the gear shaft. The sleeve is completely inserted into the gear shaft 12 corresponding to the first front storage position, and the handle is rotated clockwise. The sleeve at the end of the main shaft of the hand crank handle 11 rotates clockwise, which will drive the gear shaft 12 to rotate clockwise. The gear shaft 12 drives gear I48 to rotate clockwise, gear I48 drives gear II49 to rotate counterclockwise, and gear II49 drives the gear-shaped transmission shaft 42 clockwise. Rotate, the gear-shaped transmission shaft 42 drives all the cross bars Ⅰ32 corresponding to the first front storage position to extend, when the position of the gear rod Ⅱ35 is outside the U-shaped square tube 39, the slider 311 cannot continue to extend under the limit of the limit plate 310, and the cross bar Ⅰ32 is in a fully extended state. The staff uses a crane to lift 2 stainless steel pipes with a length of 6000mm, a wall thickness of 1.5mm and an outer diameter of 12mm one by one into the first front storage position, and the gear rod Ⅰ34 and the gear rod Ⅱ35 are used to prevent the stainless steel pipe from rolling back and forth. The storage work is completed, and the staff shakes the hand crank 11 counterclockwise, and according to the above-mentioned reverse transmission steps, the first front storage position will retract to the initial position, and the work of storing 2 stainless steel pipes with a length of 6000mm, a wall thickness of 1.5mm and an outer diameter of 12mm is completed. Specific embodiment 2:

[0051] According to the storage information entered into the storage position and the control tablet 14 in the specific embodiment 1, the staff can press the virtual button corresponding to the pipe storage position to be accessed on the screen of the control tablet 14 to extend and retract the storage position, or use the remote control to press the corresponding button, and the transmitter in the remote control sends instructions to the control tablet 14, and the control tablet 14 sends instructions to the controller in the power distribution control box 6.

In this specific embodiment, we describe the operation of the control tablet 14 to automatically control the telescopic pipe shelf;

[0052] We need to take out three polyethylene pipes with a length of 6500 mm, a wall thickness of 0.4 mm, and an outer diameter of 20 mm, which are stored in sufficient quantity on the telescopic pipe rack. The staff only needs to enter keywords in the control tablet 14, find and select the correct option, click the confirm virtual button, and the control tablet 14 will accurately associate according to the entered information and send information to the controller in the distribution control box 6. The controller controls the drive motor 13 corresponding to the second rear storage position to start working, and the drive motor 13 drives the gear-shaped transmission shaft 42 to rotate clockwise. The gear-shaped transmission shaft 42 drives all the cross bars Ⅰ32 corresponding to the second rear storage position to extend.
