Embodiment 1

[0062] like 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] like 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 the an...

Embodiment 2

[0091] This embodiment discloses a positioning method using the above-mentioned precise positioning device for a train loading carriage, comprising 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 carriage 3 to move;

[0093] s2. When the carriage 3 travels to the track scale 2, the inner flange of the wheel of the carriage 3 is pressed against the movable end of the swing arm 42 to make it swing, the detection sensor 45 detects the swing signal of the swing arm 42, and transmits the signal to the control unit, It means that the carriage 3 starts to travel to the track scale 2, or the signal is detected and fed back through the photoelectric switches on both sides of the carriage 3;

[0094] s3. When the carriage 3 starts to travel to the rail scale 2, the detection value of the train loading vehicle position detector 7 is defined as the zero position of...

Abstract

The invention discloses a train loading carriage precise locating device and locating method. The device includes a track scale, and a train weighing detector, and further includes a train loading vehicle location detector, and a control unit. Carriages are pulled through a winch and a wire rope, and the railroad track scale, the train weighing detector, the winch, and the train loading vehicle location detector are connected with the control unit separately. The method includes the steps that the carriages move, the train weighing detector detects that the carriages get on the track scale, adetection numerical value of the train loading vehicle location detector is defined as an on-scale zero location, the moving length of the wire rope detected by the train loading vehicle location detector from the on-scale zero location is a moving distance of the whole carriages, and the locations of the carriages can be controlled through the winch. The locating device has the advantages that the precise locating of the carriages can be achieved, the statement of error accumulation in the prior art is prevented, and the precise locating of the locations of the carriages during loading can beguaranteed.

Description

technical field [0001] The invention relates to the field of train positioning, in particular to a precise positioning device and a positioning method for a train loading carriage. Background technique [0002] When loading coal in a train car, a winch is usually used to pull the steel cable, and the steel cable pulls the iron bull connected to the car to pull the entire car to move. For example, the Chinese invention patent application with publication number CN110187690A discloses a precise automatic loading control for railway freight. In the system, one end of the steel cable is connected to the freight train, and the other end is connected to the shunting winch. The shunting winch moves and pulls the steel cable to adjust the position of the carriage. At about 1000 meters, the elastic deformation of the wire rope is relatively large. With the continuous loading of the train, the weight of the train continues to increase, the inertia of the train and the friction between...
