[0023] The specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0024] like Figure 1 and Figure 2 As shown, an armored loading platform that can perform secondary positioning of a material box includes a loading platform main frame, which is a rectangular frame structure. The loading platform main frame includes a horizontally arranged loading platform base 1, and a first side panel 2 and a second side panel 3 are vertically arranged on the left and right sides of the loading platform base 1, respectively. A top bracket 4 is arranged above the loading platform base 1, and the left and right sides of the top bracket 4 are respectively connected to the top ends of the first side panel 2 and the second side panel 3, and the bottom ends of the first side panel 2 and the second side panel 3 are connected to the left and right sides of the loading platform base 1.

[0025] like Figure 1 and Figure 2 As shown, the front and rear ends of the cargo platform main frame are doorways for cargo entry and exit. Armored rolling shutters are installed at the doorways. Under normal operating conditions, the armored rolling shutters are in the retracted state, and the doorway is open to allow cargo to enter and exit freely. In the event of a fire, the armored rolling shutters can close the doorway.

[0026] like Figure 1 and Figure 3 As shown, the armored rolling door includes a rolling door cover 5 mounted on top of the cargo platform's main frame. A reel is mounted within the cover 5, one end of which is connected to a reel motor, which in turn is connected to a rolling door curtain 6. When the reel motor is operating, it drives the reel, which in turn reels the rolling door curtain 6. Rolling door proximity switches 7 are located on the upper and lower portions of the left and right sides of the door opening, respectively, to monitor whether the rolling door curtain 6 is properly opened or closed.

[0027] like Figure 2 and Figure 3 As shown, an automatic telescopic fork 8 is installed within the main frame of the loading platform. The automatic telescopic fork 8 can carry a material box and move the carried material box in and out of the door opening of the loading platform main frame. The upper surface of the automatic telescopic fork 8 is provided with an anti-slip sticker to prevent the material box from slipping on the surface of the automatic telescopic fork 8. The upper fork of the automatic telescopic fork 8 is designed with V-shaped openings at both ends along the length direction. The V-shaped openings can cooperate with the positioning pins of the charging and discharging warehouse, improving the positioning accuracy of the stacker and the charging and discharging equipment.

[0028] like Figure 2 and Figure 3 As shown, mounting brackets 10 are symmetrically provided on the left and right sides of the automatic telescopic fork 8, and a material box guide assembly is provided on the mounting bracket 10, which can guide the material box in and out of the main frame of the loading platform.

[0029] like Figure 2 and Figure 3 As shown, the bin guide assembly includes a long, strip-shaped guide bar 9, which is removably bolted to the side of a mounting bracket 10. The distance between the guide bar 9 and the bin side can be adjusted as needed during use. The guide bar 9 is made of a wear-resistant material, providing a guiding function while minimizing damage to the bin.

[0030] like Figure 4 As shown, the mounting bracket 10 is provided with a hook assembly and a straightening assembly at the front and rear ends. The hook assembly can move the material box to correct the deflected material box in the longitudinal direction, while the straightening assembly can correct the deflected material box in the width direction. The cooperation of the hook assembly and the straightening assembly achieves secondary positioning of the material box when the automatic telescopic fork 8 is loaded.

[0031] like Figure 5 As shown, the hook-pull assembly includes a hook-pull electric telescopic rod 11 fixed to the upper end face of the mounting bracket 10. The telescopic end of the hook-pull electric telescopic rod 11 is connected to the hook-pull motor 13, and the driving end of the hook-pull motor 13 is connected to the hook-pull finger 12. When working, the hook-pull electric telescopic rod 11 can drive the hook-pull motor 13 and the hook-pull finger 12 to move closer to or away from the material box. The hook-pull finger 12 can drive the hook-pull finger 12 to rotate. Under normal conditions, the hook-pull finger 12 is parallel to the side of the material box. When the material box needs to be repositioned, after the hook-pull electric telescopic rod 11 is extended to the specified length, the hook-pull motor 13 drives the hook-pull finger 12 to rotate 90° perpendicular to the side of the material box. After receiving the signal, the hook-pull electric telescopic rod 11 retracts, and the hook-pull finger 12 hooks the material box and pulls it back to the correct position.

[0032] like Figure 6As shown, the straightening assembly includes two electrically operated telescopic straightening rods 14 fixed to a mounting bracket 10. The telescopic ends of the two electrically operated telescopic straightening rods 14 are connected to a straightening push rod 15. A push rod guide strip 16 made of a wear-resistant material is provided on the end surface of the push rod 15 facing the material bin. During operation, the two electrically operated telescopic straightening rods 14 push the push rod 15, which then straightens the deflected material bin. After the process is completed, the two electrically operated telescopic straightening rods 14 retract to their original positions.

[0033] like Figure 4 As shown, the jacking components are symmetrically arranged on the left and right sides of the automatic telescopic fork 8. The jacking components can push the material box away from the upper end surface of the automatic telescopic fork 8. After the material box is positioned for the second time, the jacking components are reset to place the material box back on the upper surface of the automatic telescopic fork 8.

[0034] like Figure 7 As shown, the lifting assembly includes two electric telescopic lifting rods 17 vertically fixed to the bottom end of the main frame of the loading platform. The telescopic ends of the two electric telescopic lifting rods 17 are connected to a lifting plate 18, which is located below the material box. In the normal state, the upper surface of the electric telescopic lifting rods 17 is 20mm lower than the upper surface of the automatic telescopic forks 8. In the working state, the electric telescopic lifting rods 17 drive the lifting plate 18 upward, pushing the material box 30mm away from the automatic telescopic forks 8. After completing the secondary positioning task, the lifting assembly resets and places the material box back on the upper surface of the automatic telescopic forks 8.

[0035] like Figure 4 As shown, sensor mounting brackets 29 are respectively provided at the front and rear ends of the mounting bracket 10. An extra-high beam photoelectric sensor transmitter 30 and an extra-high beam photoelectric sensor receiver 31 are respectively provided on the two sensor mounting brackets 29 located at the front ends of the two mounting brackets 10. The extra-high beam photoelectric sensor transmitter 30 and the extra-high beam photoelectric sensor receiver 31 are located at the same height. An extra-wide beam photoelectric sensor transmitter 32 is provided at the upper end of the mounting bracket 10. An extra-wide beam photoelectric sensor receiver 33 is provided directly below the extra-wide beam photoelectric sensor transmitter 32. The extra-wide beam photoelectric sensor receiver 33 is provided on the bottom end surface of the cargo platform main frame. An extra-long beam photoelectric sensor transmitter 34 is provided at the upper end of the sensor mounting bracket 29. An extra-long beam photoelectric sensor receiver 35 is provided diagonally from the extra-long beam photoelectric sensor transmitter 34. The extra-long beam photoelectric sensor receiver 35 is provided on the bottom end surface of the cargo platform main frame. A material-receiving photoelectric sensor transmitting end 36 is provided on a sensor mounting bracket 29 located at the rear end of the mounting bracket 10, and a material-receiving photoelectric sensor receiving end 37 is provided on a sensor mounting bracket 29 located at the front end of the mounting bracket 10. The material-receiving photoelectric sensor transmitting end 36 and the material-receiving photoelectric sensor receiving end 37 are arranged diagonally.

[0036] The present invention sets up a pair of through-beam photoelectric sensors to detect whether the material box enters the main frame of the loading platform, and then arranges a pair of through-beam photoelectric sensors in the directions of the material box being overlong, overwide, and overhigh for detection. When the position of the material box is skewed, the photoelectric sensor will sound an alarm and start the automatic adjustment program. The hook and pull component, the push component and the jacking component will work to adjust the material box. After the program is completed, the position of the material box will be judged again. If the position of the material box is correct, the alarm will be lifted.

[0037] After the adjustment process begins, a pair of lifting assemblies activates to lift the container from the automatic telescopic forks 8. Then, the two pairs of hook-pull assemblies in front and behind the container begin to extend to the designated position. After the hook-pull fingers 12 rotate from the waiting position to the working position, the hook-pull assemblies retract and reset the deflected container. Then, the straightening assembly begins to extend and pushes the container to the center of the loading platform, completing the secondary positioning of the container. After the secondary positioning is completed, the hook-pull and straightening assemblies sequentially withdraw from the container and return to the non-working position. The lifting assembly slowly descends, placing the container back on the automatic telescopic forks 8, completing the secondary positioning process.

[0038] like Figure 2 and Figure 3 As shown, a first camera 19, a second camera 20, and a third camera 21 are respectively installed on the top of the cargo platform main frame. The first camera 19 faces the door opening at the front end of the cargo platform main frame and is used to observe the status of the material boxes in the front cargo compartment. The second camera 20 faces the door opening at the rear end of the cargo platform main frame and is used to observe the status of the material boxes in the rear cargo compartment. The third camera 21 faces the interior of the cargo platform main frame and is used to observe the status of the material boxes inside the cargo platform main frame.

[0039] like Figure 2 and Figure 3 As shown, a fire extinguishing assembly is provided inside the cargo platform main frame. The fire extinguishing assembly can promptly extinguish a fire in the event of a fire inside the cargo platform main frame. The fire extinguishing assembly includes a temperature smoke detector, a fire extinguisher 22, and a high-pressure nozzle 23. The temperature smoke detector is provided inside the cargo platform main frame. The fire extinguisher 22 is fixed to one side of the exterior of the cargo platform main frame. The outlet end of the fire extinguisher 22 is connected to two high-pressure nozzles 23 through pipelines. The two high-pressure nozzles 23 are provided on the top of the cargo platform main frame. A switch solenoid valve is provided at the outlet end of the fire extinguisher 22. The switch solenoid valve is electrically connected to the temperature smoke detector. When the temperature smoke detector detects a fire inside the cargo platform main frame, the temperature smoke detector sends an opening signal to the switch solenoid valve. The gas in the fire extinguisher 22 then quickly reaches the high-pressure nozzle position along the pipeline and is sprayed onto the surface of the material box.

[0040] like Figure 2 and Figure 3As shown, a layer of heat insulation board 24 is provided inside the main frame of the cargo platform. The heat insulation board 24 is located directly above and on the left and right sides of the material box. The main function of the heat insulation board 24 is to control the fire inside the heat insulation board when a fire occurs in the material box, thereby protecting the components inside the cargo platform and reducing equipment losses.

[0041] like Figure 1 and Figure 2 As shown, safety clamp assemblies 27 are provided on the left and right sides of the main frame of the cargo platform. The jaws of the safety clamp assembly 27 are arranged on the surface of the column. The safety clamp assembly 27 cooperates with the speed limiter to protect the cargo platform in the case of weightlessness and overspeed, and the cargo platform is stuck on the column to prevent the cargo platform from directly hitting the ground and causing serious losses.

[0042] like Figure 1 and Figure 2 As shown, lifting wire ropes 28 are set on the left and right sides of the cargo platform main frame. The lifting wire ropes 28 are connected to the lifting motor and can drive the cargo platform main frame to rise and fall.

[0043] like Figure 1 and Figure 2 As shown, the left and right sides of the main frame of the cargo platform are respectively provided with a plurality of positive guide wheels 25 and a plurality of side guide wheels 26, which are arranged perpendicular to each other. The positive guide wheels 25 and the side guide wheels 26 press on different surfaces of the columns to guide the operation of the cargo platform.

[0044] The present invention realizes automatic adjustment of mispositioned material boxes through the coordinated arrangement of hook-pull components, push-correction components and jacking components, effectively reduces the number of manual interventions, and improves the positioning accuracy and automation level of the stacker equipment; the present invention is provided with multiple cameras and fire-extinguishing components, which can monitor the equipment status in real time, check for safety hazards at the first time, and improve production safety; the present invention is provided with an armored rolling shutter door, which can make an emergency response in time when a fire occurs, create a sealed environment to control the fire, and effectively reduce property losses.
