[0035] The following describes two implementation modes of the present application in detail with reference to the accompanying drawings.

[0036] The first implementation method:

[0037] Figure 1-7 Shown is an anti-slip and anti-overturning structure for assisting forklift handling, comprising a forklift body 1, a working end of the forklift body 1 being fixedly connected to a forklift frame 2;

[0038] The forklift frame 2 includes a lifting frame body, a movable end of the lifting frame body is fixedly connected to a bracket 21, a pair of forklift arms 22 are fixedly connected to the bracket 21, and an auxiliary stabilizing structure is fixedly connected to the upper end of the bracket 21;

[0039] The auxiliary stabilizing structure includes an adjustment box 3, both ends of the adjustment box 3 are equipped with electric telescopic rods, the movable end of the electric telescopic rod is rotatably connected to an auxiliary arm 4, the movable end of the electric telescopic rod is connected to a C-shaped bracket, and the outer wall of the auxiliary arm 4 is located inside the C-shaped bracket and slides relative to the inner wall of the C-shaped bracket;

[0040] The telescopic end of the auxiliary arm 4 is rotatably connected to the stabilizing plate 5 via a rotating shaft; the top of the stabilizing plate 5 is fixedly connected to a motor matching the rotating shaft;

[0041] The top of the bracket 21 is fixedly connected with a rotating motor 7 matched with the auxiliary arm 4, the power output end of the rotating motor 7 is fixedly connected with a rotating shaft, the telescopic end of the rotating shaft is fixedly connected with the auxiliary arm 4, and one end of the rotating shaft passes through the auxiliary arm 4 and is rotatably connected with the outer wall of the adjustment box 3;

[0042] The auxiliary arm 4 includes a shell connected to the electric telescopic rod, an extension arm 41 is inserted into one end of the shell, the extension arm 41 is rotatably connected to a movable plate 42, the movable plate 42 is limitedly slidably connected in the shell, and a servo motor 43 matching the extension arm 41 is fixedly connected in the shell.

[0043] The stabilizing plate 5 includes a main shell 51, a pair of slide grooves are opened at the bottom end of the main shell 51, and an auxiliary stabilizing frame 6 is slidably connected between the pair of slide grooves; the auxiliary stabilizing frame 6 includes a pair of slide rods 61, and a hanging plate 62 is connected between the pair of slide rods 61; a plurality of airbag belts are fixedly connected to the hanging plate 62, and an inflation tube 9 communicating with the plurality of airbag belts is passed through the main shell 51.

[0044] The inflation tube 9 includes a fixed tube passed through the main shell 51, a first solenoid valve is connected between the fixed tube and a pair of movable grooves, an output end of the fixed tube is connected to a corrugated air tube connected to the airbag belt through a second solenoid valve, an elastic air guide tube is connected between the input end of the fixed tube and the regulating box 3, and an air pump matching the elastic air guide tube is fixedly connected to the regulating box 3.

[0045] One end of the slide rod 61 located in the slide groove is fixedly connected to a piston block 63, and a movable groove matching the piston block 63 is opened in the slide groove. A piston cylinder 52 is fixedly connected to the main shell 51, and an air pipe is connected between the piston cylinder 52 and the slide groove. A piston column is installed on the movable end of the piston cylinder 52 and is slidably set in the air pipe. A one-way air valve 8 is connected to the output end of the air pipe, and the air pipe is filled with protective gas.

[0046] The one-way air valve 8 includes a valve housing 81, and a sealing valve cover 82 is slidably connected to the opening of the valve housing 81. When the sealing valve cover 82 is opened, it moves into the movable groove. A pressure-stabilizing telescopic column 83 is connected between the sealing valve cover 82 and the valve housing 81. The telescopic end of the pressure-stabilizing telescopic column 83 is fixedly connected to a permanent magnet. An electromagnet matching the permanent magnet is fixedly connected to the valve housing 81. When the electromagnet is working, it repels the permanent magnet, thereby extending the pressure-stabilizing telescopic column 83 and opening the sealing valve cover 82.

[0047] Optionally, by controlling the operation of the electromagnet to adjust the pressure of the pressure-stabilizing telescopic column 83 on the sealing valve cover 82, the sealing valve cover 82 will be opened only when the set air pressure is reached in the movable groove, thereby adjusting the opening timing of the sealing valve cover 82 after the hanging plate 62 is displaced due to the sliding of the goods;

[0048] A pair of electric push rods matching the slide rod 61 are fixedly connected to the rear end of the main housing 51 , and a buffer spring that fits the end surface of the piston block 63 is fixedly connected to the movable end of the electric push rod.

[0049] When this solution is working, the cargo is placed on a pair of forklift arms 22, and then the adjustment box 3 is controlled to make a pair of electric telescopic rods work to adjust the position of the auxiliary arm 4;

[0050] Then the rotating motor 7 is controlled to work, so that the rotating shaft drives the auxiliary arm 4 to rotate, and at the same time, the auxiliary arm 4 is controlled to make the stabilizing plate 5 close to the top of the cargo.

[0051] Then the electric push rod is controlled to work, so that the auxiliary stabilizing frame 6 is pushed outward until the hanging plate 62 is close to the edge of the cargo.

[0052] Then the stepper motor is controlled to work, so that the bottom end of the stabilizing plate 5 is in contact with the goods, and the hanging plate 62 is in contact with the edge of the goods, and the position of the stabilizing plate 5 is now positioned;

[0053] Then, the auxiliary stabilizing frame 6 is adjusted for stability. During the adjustment, the air pump is controlled to work to inflate the movable groove, thereby causing the piston block 63 to move toward the inside of the main housing 51 until the hanging plate 62 is in contact with the edge of the cargo. During the inflation process, the electric push rod is synchronously controlled to work so that its movable end is always in contact with the piston block 63 and maintains the set pressure. When the pressure value detected by the pressure sensor on the hanging plate 62 reaches the set value, the inflation is stopped, and the position of the hanging plate 62 is fixed at this time.

[0054] The main housing 51 is used to press down the top of the cargo to limit the cargo in the vertical direction, and the hanging plate 62 is used to limit the edge of the cargo to achieve stability of the shaking of the cargo during transportation;

[0055] During transportation, if the goods slide, the hanging plate 62 is squeezed to move. At this time, the piston block 63 squeezes the gas in the movable groove to open the one-way air valve 8. After detecting that the one-way air valve 8 is opened, the piston cylinder 52 works to move the movable end of the piston cylinder 52 to fill the movable groove with internal gas; to maintain the stability of the hanging plate 62, and then the hanging plate 62 prevents the goods from further sliding, thereby achieving the stability of the goods.

[0056] The auxiliary arm 4, the stabilizing plate 5 and the auxiliary stabilizing frame 6 of the present solution are all conveniently adjusted to adapt to the handling of different types and sizes.

[0057] Second implementation method:

[0058] Figure 8 As shown, an air pressure sensor is installed in the movable groove, a displacement sensor is installed in the piston block 63, and a pressure sensor is installed on the hanging plate 62.

[0059] The anti-slip and anti-overturning structure also includes an auxiliary handling system, which includes a processor installed on the forklift body 1, and the processor is connected to a control module, a monitoring module, a data processing module and a data storage module;

[0060] A control module, used for controlling the operation of the auxiliary stabilizing structure;

[0061] A monitoring module, used to collect monitoring data, including: air pressure data in the movable groove, positioning data of the piston block 63 and pressure data;

[0062] The data processing module is used to process and analyze the monitoring data, determine the status of the goods being transported based on the analyzed data, and call the control module to execute the preset working procedures based on the status of the goods;

[0063] The data storage module is used to store monitoring data and work logs.

[0064] When the auxiliary handling system is working, the processor receives the monitoring data from the monitoring module in real time, and then conducts a comprehensive analysis of the data to determine whether the goods are stable during the handling process.

[0065] During the handling process, if the air pressure change in the movable groove is monitored, it indicates that the piston block 63 is displaced, and the positioning information of the piston block 63 is monitored. If the displacement sensor of the piston block 63 detects that the position of the piston block 63 deviates from the preset value, the control module is called to execute the preset working procedure to assist in stabilizing the goods;

[0066] Specifically, when the control module executes the preset working procedure, it controls the rotating motor 7 to rotate the auxiliary arm 4, thereby pressing the cargo stably, and at the same time controls the piston cylinder 52 to work so that the gas in the gas pipe is filled into the movable groove to stabilize the piston block 63, thereby ensuring that the hanging plate 62 stably limits the cargo and ensures that the cargo does not slide further.

[0067] In addition, the pressure sensor will continuously monitor the pressure changes on the hanging plate 62. Once the pressure is abnormal, such as exceeding the set safety range, the surface cargo will have a serious tendency to move outward, and the system will issue an alarm to enable the operator to discover it in time.

[0068] The data storage module will record all monitoring data and work logs to facilitate subsequent analysis and optimization of the handling process. Through these measures, the auxiliary handling system of this solution can effectively improve the safety and efficiency of forklift handling.

[0069] In summary, this solution uses an adjustable auxiliary arm 4, a stabilizing plate 5 and an auxiliary stabilizing frame 6, and monitors the cargo transportation process, so as to facilitate the stable transportation of cargo of different types and sizes, and ensure that the cargo is not easy to shake, slide or overturn when the forklift transports the cargo.

[0070] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
