Specifically, the unlocking mechanism of the cab-side sliding window 30 is a set of mechanical link structure, and the mechanical link structure is connected with the opening and closing cover of the door control box 40 through a pin shaft. The action process is as follows: when the three-position five-way solenoid valve 64 for controlling the second piston cylinder 52 is turned on, the piston in the valve of the three-position five-way solenoid valve 64 acts, the gas flow direction on the second branch 62 changes, so that the second piston cylinder 52 extends or retracts, and the switch cover of the door control box 40 is driven to move, the switch cover of the door control box 40 drives the mechanical link structure to act, the mechanical link structure drives the lock pin to move away from the moving track of the cab-side sliding window 30, so that the cab-side sliding window 30 is unlocked, and at the moment, the cab-side sliding window 30 can be opened manually.
This embodiment provides compressed air for two pneumatic pistons through two automatically controlled air valves of circuit control, and then drives door control box switch cover and driver's cabin side sliding window respectively and realizes reciprocating motion. The door control box action and the cab side window pulling action are combined through the time delay relay, a real operation sequence is simulated, the durability of the three components (the door control box, the cab side window pulling action and the interlocking mechanism) is verified at the same time, and the problems that a single component cannot completely simulate real operation conditions and is incomplete in verification in a durability test are solved.
The durability test device 10 of this embodiment includes two piston cylinders, and two piston cylinders are connected with gate box switch cover, driver's cabin side sliding window handle respectively. Each piston cylinder controls a throttle valve to realize reciprocating motion through a three-position five-way electromagnetic valve, so that the action of opening and closing a door control box opening and closing cover and the action of opening and closing a side sliding window are simulated. The end part of the gas circuit system is provided with a ball valve and a pressure reducing valve so as to adjust the gas pressure and realize different action speeds.
