The number and location of the fender 1 and the air bags 4 may be arranged as desired in practice depending on the size of the cargo box. As shown in fig. 7, in this embodiment, a protection plate 1, two sets of telescoping mechanisms 2, and an airbag 4 are oppositely installed on a container wall 6, and two airbags 4 are connected to an outlet of a two-position three-way cutoff cock 3.11 to protect two pallet loads 7.
The tray goods telescopic protection device is defaulted to be at the maximum release position shown in figures 3 and 5, when the tray goods telescopic protection device is used for the first time or no pressure air exceeding the constant pressure exists in the air storage tank 3.5, the two-position three-way cutoff cock 3.11 is closed, the main cutoff cock 3.1 and the reset cock 3.7 are opened, the pressure air enters the air filter 3.2 through the main cutoff cock 3.1, and the filtered pressure air flows to the low-pressure one-way valve 3.3. When the air pressure of the pressure air exceeds the opening pressure of the low-pressure one-way valve 3.3, the low-pressure one-way valve 3.3 is opened, and the pressure air enters the air storage cylinder 3.5 through the reset cock 3.7. After the pressure gauge 3.6 displays that the pressure exceeds the constant pressure, the two-position two-way pneumatic control reversing valve (normally closed) 3.4 is converted into an opening state, the two-position two-way pneumatic control reversing valve (normally open) 3.8 is converted into a closing state, the reset plug valve 3.7 is closed, and meanwhile, the micro-pressure one-way valve 3.10 is converted into an opening state.
After the vehicle is loaded with goods, the two-position three-way intercepting cock 3.11 is placed at the opening position, and the pneumatic control system 3 is communicated with the air bag 4. And (3) a quick inflation stage: the pressure air of 3.9 exports of relief pressure valve gets into in the gasbag 4 through minute-pressure check valve 3.10, the atmospheric pressure of two lead to gas accuse switching-over valves (normally open) 3.8 control mouths reduces, two lead to gas accuse switching-over valves (normally open) 3.8 convert the open mode, the pressure air in the air storage jar 3.5 directly flows into gasbag 4 through two lead to gas accuse switching-over valves (normally open) 3.8 fast, realize the quick preliminary inflation to the gasbag, after the air pressure in the gasbag 4 is higher than the level pressure of two lead to gas accuse switching-over valves (normally open) 3.8 control mouths, two lead to gas accuse switching-over valves (normally open) 3.8 convert the closed mode into, gasbag 4 has been aerifyd the jack-up guard plate 1 this moment. And (3) a slow inflation stage: when the air pressure in the air bag 4 is higher than the opening pressure of the control end of the two-position two-way air control reversing valve (normally open) 3.8, the two-position two-way air control reversing valve (normally open) enters a closed state, the pressure air set by the reducing valve 3.9 continuously flows into the air bag 4 at a low speed until the pressure air of the air bag 4 is balanced with the pressure set by the reducing valve 3.9, the air bag 4 is inflated and stopped, the protection plates 1 on the two sides of the goods are jacked to the maximum protection position, the side faces of the goods on the pallet are tightly pressed, and the goods are jacked tightly to limit the movement of the goods.
When goods are unloaded, the two-position three-way stage cock 3.11 is arranged at a closed exhaust position, a passage between the pneumatic control system 3 and the air bag 4 is cut off, air in the air bag 4 is exhausted into the atmosphere, the air bag 4 drives the air spring 2.1 to contract, the contraction tension generated by the air spring 2.1 can shorten the air spring after the air bag is exhausted and decompressed, the pin connection point of the support rod 2.2 is pulled to move towards the contraction direction of the air spring, the support rod 2.2 drives the protection plate 1 to return to a maximum loosening position, the goods are loosened, and then the unloading operation can be carried out. The inner side face of the protection plate 1 is attached to the side wall of the cargo box, and the telescopic mechanism 2, the supporting seat 5 and the air bag 4 are hidden in a groove-shaped concave structure 6.1 of the wall body 6 of the cargo box and do not occupy the cargo space.
The setting pressure of the pressure reducing valve 3.9 is adjusted to adjust the air pressure in the air bag 4 to change the expansion jacking distance of the air bag 4, so that the stepless adjustment of the extending distance of the protection plate 1 in a certain range can be realized.
The low-pressure one-way valve 3.3 limits the opening pressure for charging the air storage cylinder 3.5 in the pneumatic control system and prohibits the pressure air in the air storage cylinder from flowing back to the vehicle brake air main pipeline to influence the vehicle brake action or performance.
And when the pressure in the downstream pipeline of the two-position two-air-control reversing valve (normally closed) 3.4 is lower than the opening pressure of the control end, the two-position two-air-control reversing valve (normally closed) enters a closed state, and air of a vehicle braking air main pipe is forbidden to flow into the air storage cylinder.
After the reset cock 3.7 of the pneumatic control system is opened, air of a vehicle brake air main pipe bypasses the two-position two-air-control reversing valve (normally closed) 3.4 and flows into the air storage cylinder 3.5.
The two-position two-way pneumatic control reversing valve (normally open) 3.8 and the pressure reducing valve 3.9 are matched for use, and two-stage control of a quick inflation stage and a slow inflation stage of inflation is realized.
The micro-pressure one-way valve 3.10 prohibits the pressure air in the air bag from flowing back to other positions through the micro-pressure one-way valve in the pneumatic control system.
The pressure reducing valve 3.9 can be connected with a plurality of one-way valves and the downstream components and pipelines in parallel to meet the requirement of multi-path respective control.
The invention uses pressure air as a power source for moving the baffle plate 1 to a working position, and the pneumatic control system 3 adopts a pneumatic control structure of a two-position two-way pneumatic control reversing valve (normally closed) 3.4, so that when the air pressure in the air storage cylinder is lower than low pressure due to leakage of a pipeline at the downstream of the two-position two-way pneumatic control reversing valve (normally closed) 3.4 or other factors, the passage of the two-position two-way pneumatic control reversing valve (normally closed) 3.4 is closed, and the air is prevented from being continuously inflated into the air storage cylinder.
