Embodiment 1
[0062] Such as Figure 1-3 As shown, a precise positioning device for a train loading compartment includes an anti-climbing rail 1, a track scale 2, a compartment 3, a train weighing and overweight detector 4, a winch 5, a steel cable 6, a train loading vehicle position detector 7, and a control unit.
[0063] The control unit in this embodiment adopts PLC, which is an existing technology, and those skilled in the art can program it according to actual needs to realize the control function described in this embodiment.
[0064] Such as figure 1 As shown, the track scale 2 is a static track scale, which is arranged between two sections of anti-climbing rails 1, with the moving direction of the compartment 3 as the front (moving direction during coal loading), and the rear end of the track scale 2 and the anti-climbing rail The inner side of the junction of 1 is provided with a train weighing and weighing detector 4, and the outer side of the junction of the track scale 2 and ...
Embodiment 2
[0091] This embodiment discloses a positioning method using the above-mentioned precise positioning device for the train loading compartment, which includes the following steps:
[0092] s1. The control unit controls the operation of the winch 5, the winch 5 pulls the steel cable 6 to move, and the steel cable 6 pulls the entire train compartment 3 to move;
[0093] s2. When the carriage 3 moves onto the track scale 2, the inner flange of the wheel of the carriage 3 presses against the movable end of the swing arm 42 to make it swing, and the detection sensor 45 detects the swing signal of the swing arm 42, and sends the signal to the control unit, It means that the carriage 3 starts to walk on the track scale 2, or the signal is fed back through the photoelectric switches on both sides of the carriage 3;
[0094] s3. When the compartment 3 starts to go on the track scale 2, the detection value of the train loading vehicle position detector 7 is defined as the zero position of...
