Description

Method for preventing railway container F-TR lock flat car from derailing during unloading

Technical Field

The invention relates to a control method for preventing derailment of a railway container F-TR lock flat car in the unloading process.

Background

The F-TR lock of the railway container is automatically put into operation, and has become the main locking type of the special railway container flat car and the NX70A flat car at present due to simple structure, durability, moderate locking performance and smoothness. The unique eagle head structural design of the F-TR lock of the railway container ensures that the container and a railway freight car are not separated and overturned in the railway transportation process, ensures the safety of the container in the transportation process, solves the safety problem of preventing the container from falling by binding and reinforcing, and causes the safety problems of derailment of the car, no falling lock of container corner fittings and the like in the operation process of loading and unloading the container. Because the existing container loading and unloading machinery lacks a safety sensing and monitoring device and is operated by a driver, four corner fittings at the bottom of the container cannot be completely separated from an F-TR lock and can be lifted together with the container, a vehicle is lifted off a track, corner fitting holes of the container are damaged, a lock head of a railway wagon is damaged, and even a railway vehicle derailment accident is caused.

Disclosure of Invention

The invention aims to provide a method for preventing a railway container F-TR lock flat car from derailing, which overcomes the defect that the existing loading and unloading machine is easy to cause the derailing of a vehicle when unloading a container loaded by the F-TR lock flat car.

A railway container F-TR lock flat car unloading derailment prevention method is characterized by comprising the following steps:

the method comprises the following steps that firstly, a container loading and unloading machine is provided with an F-TR lock flat car height detection device, a lifting low-speed gear starting automatic stop device and a view screen auxiliary device;

step two, the container handling machinery automatically or a driver operates to align and lock a container hanger of the container handling machinery and a container and control the spin lock to be in a locking state;

step three, automatically or by a driver, controlling a container loading and unloading machine to lift a low-speed gear to start an automatic stop device, simultaneously detecting and judging the distances between four corner fittings at the bottom of a container and an F-TR lock flat car by an F-TR lock flat car height detection device, automatically stopping low-speed lifting if the distances between the four corner fittings and the F-TR lock flat car reach 100mm, and confirming whether the four corner fittings at the bottom of the container are completely separated from the F-TR lock by an operator through a view screen auxiliary device;

step four, if the container is completely separated, quickly lifting and hoisting the container; if not, the driver operates or automatically controls the container to fall onto the flat car, and the step three is repeated until the four corner fittings at the bottom of the container are completely separated from the F-TR lock to quickly lift and lift the container.

Furthermore, a lifting height detection device is installed on the container handling machine, an F-TR lock flat car height detection device is installed on the lower portion of a main beam or a trolley of a container gantry crane, the height value is dynamically detected, the distance between four corner fittings at the bottom of the container and the F-TR lock flat car is obtained through two height values, and the operation is carried out according to the steps from the second step to the fourth step.

The invention has the advantages that: by installing the F-TR lock flat car height detection device, the lifting low-speed gear starting automatic stop device and the view screen auxiliary device on the conventional container handling machine, a driver operator can accurately control the container handling machine to stop when the distance between four corner pieces of a container and a flat car reaches 100 millimeters, and then judge whether the four corner pieces at the bottom of the container are completely separated from the F-TR lock. The container loading and unloading machine can lift at low speed to leave the F-TR lock of the vehicle and stop automatically without the confirmation and command of ground auxiliary personnel, can control the magnitude of the lifting speed and the lifting height, and solves the problems that the corner piece hole of the container is connected with the F-TR lock head of the rail wagon, the corner piece hole of the container is damaged due to the dead locking of the corner piece hole of the container and the F-TR lock head of the rail wagon, and the rail wagon lock head is damaged or even causes the derailment accident of the rail wagon. According to the regulations of technical rules for goods handling safety of railways, when a container loaded by a goods wagon is unloaded, the container handling machine needs to stop lifting when the container is inching and lifting at a low speed for 100mm, so that the lifting operation can be continued after the container is smoothly separated from the goods wagon. However, the accuracy of manual operation of the existing equipment is low, the aim of automatically stopping lifting operation when the low-speed inching lifting is 100mm cannot be accurately achieved, each lifting needs to be manually and repeatedly inching operated and then is emergently braked, the lifting height often exceeds 100mm in the actual lifting process, but a container is not separated from a railway freight car, and the corner fitting hole of the container is damaged, the lock head of the railway freight car is damaged or the railway freight car is derailed. The method accurately measures the height difference and automatically controls the equipment to operate by installing the detection device, and ensures safety by physical defense and technical defense. The method can reduce the labor cost, and has obvious economic benefit because the prior method of ensuring the operation safety stipulates that one loading and unloading device needs to be provided with at least 3 persons for operation and reduces the operation cost into the method that 1 person of a driver can operate one or more devices. The method can also realize automatic unloading of containers loaded by the F-TR lock flat car, thereby ensuring safety and reducing the labor intensity of workers.
