What is Easy Hump Mechanized Hump Automated Hump? What is the difference between push methods?

The hump is the main feature of the marshalling station, it is a small hill built on the ground like the shape of the back of a camel's hump, designed with an appropriate slope, the railway is laid on it, and the potential energy generated by the gravity of the vehicle and the slope of the hump is supplemented by the locomotive thrust to dismantle the train is a kind of shunting equipment, which is a main method of dismantling the train in the marshalling station. When carrying out the hump shunting operation, the train is pushed to the hump by the shunting machine first, and when the front car group (or vehicle) is close to the peak, lift the hook, then you can use the gravity of the vehicle itself, automatically slip down the slope to the predetermined line of the marshalling yard, so that the efficiency of the shunting operation can be greatly improved. The camel bee is generally located at the head of the shunting yard, which is suitable for the dismantling operation of the train.

Humps can be divided into simple humps, non-mechanized humps, mechanized humps, semi-automated humps and automated humps according to different equipment conditions.

The range of the hump refers to a part of the line segment between the pre-peak arrival yard (the pull-out line when there is no pre-peak arrival yard) and the shunting yard, including the push part, the slip part and the peak platform.

Push part - refers to the line range of the full length of the train when the first hook car is located at the summit of the train that has been disintegrated by the hump. The purpose of setting this part is to make the vehicle obtain the necessary potential energy, and to make the coupler compressed, so that the hook can be easily removed.

Slip part - from the peak to the head of the marshalling yard after the 100 meters (mechanized hump) or 50 meters (non-mechanized hump or simple hump) after the road police mark. This length is called the calculated length of the hump, and the end of the calculated length is called the calculated stopping point of the hump. Because the warning mark of the shunting line is not in the same transverse position, each shunting line has a calculated parking point.

This point is only based on calculations and is not marked at the site.

Peak Platform - A flat section of land at the junction between the push and slide sections.

One of the most effective measures to strengthen the railway marshalling yard is the automation of the hump. The automation of hump shunting operation mainly includes: automatic adjustment and automatic control of vehicle slip speed; automatic selection and automatic control of vehicle slip-in approach; automatic adjustment and automatic control of the pushing speed of the hump locomotive; Automation of air duct extraction and hook lifting, etc.

The most important and critical of the above items is the automatic control of the vehicle's slip speed, which is the core content of hump automation. When the train is dismantled at the hump marshalling station, in order to ensure the safety and operation requirements, a speed regulating tool must be set up at a certain place, and the sliding speed of the vehicle must be adjusted according to the needs to meet the operational requirements.

The achievements of modern science and technology, especially the rapid development of electronics, automatic control theory and computer technology, have created conditions for the realization of the goal of automatic adjustment and automatic control of vehicle speed.
