Embodiment 1

[0038] like image 3 As shown, a front stacker container anti-derailment automatic control method comprises the following steps:

[0039] A. After closing the anti-derailment enabling switch, the locking sensor installed on the spreader is used to detect whether the spreader and the container are locked; when the spreader and the container are locked, the locking sensor will send a locking signal sent to the vehicle controller;

[0040] B. When the spreader and the container are not locked, the boom of the reach stacker moves at normal speed;

[0041] C. When the spreader and the container are locked, a proportional solenoid valve is installed at the oil inlet end of the lifting cylinder. The power supply end of the proportional solenoid valve is connected to the output end of the vehicle controller, and the vehicle controller receives After the sensor signal is locked, a small current is output to control the opening of the proportional solenoid valve to become smaller, the...

Embodiment 2

[0054] An automatic control method for anti-derailment of a front stacker container, comprising the following steps:

[0055] A. After turning off the anti-derailment automatic control enabling switch, use the locking sensor to detect whether the spreader and the container are locked;

[0056] B. When the spreader and the container are not locked, the locking sensor has no signal output, the vehicle controller will not enter the anti-derailment automatic control program of the front stacker container, and the driver can quickly lift the boom to avoid affecting the normal operation;

[0057] C. When the spreader and the container are locked, the locking sensor outputs a signal to the vehicle controller, and the vehicle controller controls the lifting cylinder to make the boom rise slowly; when the boom is lifted slowly and the spreader is in the box When the sensor signal disappears, the length and angle sensors transmit the current boom length L and the angle A between it and ...

Embodiment 3

[0062] like figure 1 , 2 As shown, a front stacker container anti-derailment control system includes a vehicle controller 10, an anti-derailment enabling switch 11, a spreader 1 connected to the front end of the boom 8, and a lifting cylinder 12 for driving the boom 8 to lift. The oil inlet end of the lifting cylinder 12 is connected with a proportional solenoid valve 9 in series, and the length angle sensor 7 for detecting the length of the boom 8 and the angle between it and the horizontal line is installed on the boom 8; Proximity sensor 2 and load cell 3 are respectively installed at the lock head of the spreader, and the output ends of the length angle sensor 7, proximity sensor 2, load cell 3, and anti-derailment enabling switch 11 are all connected with the input of vehicle controller 10. The output terminal of the vehicle controller 10 is connected with the proportional solenoid valve 9 to control its opening size.

[0063] In a further solution, the proximity sensor...

Abstract

The invention provides an anti-derailing automatic control method for a container on a reach stacker. The method comprises the following steps that after an anti-derailing enabling switch is closed, whether the container is locked to the reach stacker or not is detected; when the reach stacker is separated from the container, the lifting height H1 of the reach stacker is detected; when the reach stacker continues to lift by the height H2 at low speed, a reference weight value is set; the reach stacker continues to lift by the height H3, weighing values of weighing sensors are recorded at any time in the process, and the weighing values are compared with the reference weight value correspondingly; if any weighing value is larger than the reference weight value, the lifting action of a boomis immediately stopped for overhauling; and otherwise, the reach stacker returns to normal lifting speed until the container is separated from a flat car. According to the anti-derailing automatic control method, the weighing values of the weighing sensors are collected through a vehicle controller and compared with the reference weight value, and whether the container is separated from the flat car with an F-TR lock of an eagle head structure, and located below the container or not is automatically judged according to the comparison result so as to ensure that the container is safely separated from the flat car.

Description

technical field [0001] The invention relates to a front hanger, in particular to an automatic control system and method for preventing derailment of a front hanger container. Background technique [0002] Reach stacker is the abbreviation of container reach crane. Reach stacker is a kind of crane used to load and unload containers. It belongs to a kind of lifting equipment, and it can also be said to be a mobile machine. The front stacker is to push the boom upwards by the lifting cylinder, and the boom drives the spreader to lift the container, so as to realize the lifting and stacking of the container. With the continuous increase of railway container transportation, the locking device between the container and the special flatbed car has developed from the original straight table lock, boss lock, and manual twist lock to the current fully automatic twist lock and the F with unique eagle head structure. -TR locks, especially F-TR locks for railway containers, have the adv...
