[0035] like Figure 4As shown, the main frame 1 includes a mounting frame 11 and a support frame 12. The mounting frame 11 is provided with support frames 12 on both sides. The support frames 12 are provided with bearing frames 13. The bearing frames 13 are provided with tracks 8. The bearing frames 13 located on the same horizontal plane are provided with arched trays 2. The support frames 12, the bearing frames 13 and the tracks 8 are used to carry the trays 2.

This structure enhances the connection strength between the hydraulic actuator 5 and the main frame 1, and the structure is more stable.

[0039] Before use, when the existing building ground pressure resistance is 3 tons / square meter and the unevenness is 30-50 mm, the ground can be used to build warehouse shelves without treatment. The staff determines the size of the main frame 1 when welding according to the type of goods and usage requirements. That is, the installation frame 11 is installed on the base 0, and the support frame 12 is installed on both sides of the installation frame 11. The support frame 12 is provided with multiple layers of horizontal plates 122, that is, a multi-layer bearing frame 13 can be set. The bearing frame 13 made of I-beam or H-steel is welded on the horizontal plate 122, and the bearing frame 13 is installed on the track 8. The track 8 is provided with a pallet 2 that matches it; a reinforcement plate 123 is provided between the horizontal plates 122, and a limit rod 14 and a reinforcing rod 54 are provided on the installation frame 11. The structure of the main frame 1 is stable and the connection is reliable.

[0040] When in use, the staff operates through the control panel, and the intelligent controller 7 controls the hydraulic control system 6 to make the hydraulic actuator 5 work, that is, the hydraulic cylinder 53 corresponding to the layer number of the material works, and the movable end of the hydraulic cylinder 53 moves forward to drive the pallet 2 to move forward, thereby realizing the removal or storage of the material; when the same material is removed or stored in batches, it is necessary to place the material in layers, and when in use, the material that enters the shelf first leaves first, and the material that enters the shelf later leaves later, that is, first in first out, to avoid the squeezing of old plates; during use, the main support wheel 3 supports the pallet 2, and when the main support wheel 3 moves along the track 8, the limit part 31 and the side limit wheel 4 ensure that the main support wheel 3 and the track 8 are accurately positioned; the side limit wheel 4 contacts the track 8, and it is located above the load frame 13, which plays an auxiliary support role for the pallet 2, and the pallet 2 is an arched structure, which improves the carrying capacity of the pallet 2 and ensures the reliability of use. When the pallet 2 moves to the front side of the main frame 1, the position sensor detects the position signal of the pallet 2 and transmits it to the intelligent controller 7, and the intelligent controller 7 stops the hydraulic cylinder 53 through the hydraulic control system 6. After taking out the material, tray 2 is reset in the same way.

[0041] Example 2

[0042] like Figure 7 and Figure 8 As shown, the intelligent controller 7 is a Siemens PLC st20, one side of which is the input end and the 24V circuit connection end. The emergency stop and oil pump failure of the hydraulic control system 6 are connected to the intelligent controller 7, and the position sensor and weight sensor are connected to the intelligent controller 7; the side symmetrical to the input end is the output end, and the buzzer, indicator light and the oil pump output of the hydraulic control system 6 are all connected to the intelligent controller; the side asymmetrical to the input end is the network cable connection end, and the left side of the network cable connection end is connected to the control panel, which is easy to operate and use; the intelligent controller 7 is connected to the analog input module, and the output end of the weight sensor is connected to the analog input module. Figure 8 and Fig. 9As shown, one end of the weight sensor is a signal input end, and the other end is a signal output end, and its signal output end is connected to the analog input module, and the analog input module is connected to the intelligent controller 7. Figure 7 As shown, the indicator lights include a red light for overload alarm, a yellow light for insufficient inventory alarm, and a green light indicating reasonable inventory.

[0043] When it is necessary to replenish the inventory, the corresponding information of the stored plates is fed back to the intelligent controller 7 according to the signal measured by the weight sensor, and the yellow light in the indicator light stays on. The intelligent controller 7 sends the information to the hydraulic control mechanism 6, and controls the movement of the corresponding number of pallets 2 through the hydraulic actuator 5. During the movement, according to the signal measured by the position sensor corresponding to the pallet 2, the yellow light in the indicator light flashes, and is continuously accompanied by a buzzer alarm. After the pallet 2 moves into place, the buzzer stops and the yellow light stays on. Use tools such as a crane or a forklift to place the steel plate on the pallet 2 once or multiple times. The weight sensor always transmits the measured signal to the intelligent controller 7, and the intelligent controller 7 controls the indicator light. When the yellow light in the indicator light turns green, accompanied by a buzzer alarm, the material is stopped and the indicator light is green. After the material is discharged, the information feedback device on the forklift or the crane sends a completion signal to the intelligent controller 7, and three beeps sound. The intelligent controller 7 feeds back the signal to the hydraulic control mechanism 6, and the hydraulic control mechanism 6 resets the pallet 2 through the hydraulic actuator 5. During the movement of the pallet 2, the green light flashes, accompanied by a continuous beep sound, until the pallet 2 returns to its original position, the sound is canceled, and the green light is always on. This process can ensure that the pallet 2 is reset after the material placement work is completed, ensuring the safety of use.

[0044] If too many plates are placed at one time, the weight sensor will feedback that they are overweight, the red light in the indicator light will turn on, and there will be a rapid buzzer sound. At this time, it is necessary to reduce the weight. During the weight reduction process, the weight sensor continuously monitors the signal and transmits it to the intelligent controller 7. The intelligent controller 7 controls the indicator light. When the signal light turns green, the buzzer sound is cancelled. When storing plates of multiple specifications, the plate specification information is input to the intelligent controller 7 in order according to the incoming material status, and the intelligent controller 7 repeats the above process in sequence.

[0045] When taking out the plate, the corresponding information of the required plate is fed back to the intelligent controller 7, and the intelligent controller 7 sends the information to the hydraulic control mechanism 6, and controls the movement of the corresponding number of pallets 2 through the hydraulic actuator 5. According to the signal measured by the position sensor on the main frame 1, the intelligent controller 7 makes the green light in the indicator light flash, and is accompanied by a continuous buzzer alarm. After the pallet 2 moves into place, the buzzer stops and the green light stays on. Use tools such as a crane or a forklift to take out the steel plate once or multiple times, and send a completion signal to the intelligent controller 7 through the signal feedback device of the forklift or the crane. There are 3 buzzers, and the signal is fed back to the hydraulic control mechanism 6 through the intelligent controller 7. The hydraulic control mechanism 6 resets the pallet 2 through the hydraulic actuator 5. During the movement of the pallet 2, the green light flashes, accompanied by a continuous buzzer alarm, until the pallet 2 returns to its position, the sound is cancelled, and the green light is always on.
