Topic: Principle, application and maintenance of the tongue lock of railway freezer.

With the rapid development of China's railway transportation and the escalating demand for logistics transportation, the application of refrigerated containers in railway freight transportation has gradually become widespread. In the use of refrigerated containers, it is particularly important to ensure that the box is safely and stably connected to the car body, which requires the use of a special mechanical device-the tongue lock of the railway freezer.

First, the structure and working principle of the tongue lock of the railway freezer:

The tongue lock of railway refrigerator is a special equipment installed under the underframe of railway freight car, which is mainly composed of base, tongue, lock catch, operating handle and so on. Its function is to fix the refrigerated container on the carriage to ensure the safety and stability of the transportation process.

1. The base is an integral casting or welded structure, and is fixed on the underbody beam by bolts; 2. The rotating tongue can rotate around the axis and is used to clamp or loosen the corner hole at the bottom of the refrigerator; 3. The lock catch is used to lock the rotating tongue to prevent accidental falling off; 4. The operating handle is the key component to realize the manual unlocking/locking function. Through the manual rotation of the operator, the tongue is driven to move, and then the locking or releasing of the corner hole of the container is completed, thus achieving the purpose of fixing or unloading the container.

Second, the application of railway freezer tongue lock:

With the accelerated development of economic globalization, more and more commodities need to be transported over long distances and kept fresh. In order to meet this demand, the railway department has introduced a large number of special refrigerated boxes with high-efficiency thermal insulation performance. These containers are equipped with precision refrigeration system, which can effectively control the temperature change range during transportation, so that all kinds of perishable foods, drugs and biological agents can be kept in an ideal state for a long time. As an important link between the refrigerator and the car body, the tongue lock of the railway refrigerator not only bears a huge weight load, but also relates to the safety of the whole transportation link.

Three, the maintenance of the railway freezer tongue lock:

Due to long-term exposure and frequent contact with various chemicals, it needs to be inspected and maintained regularly:

1. Cleaning and decontamination: removing surface attachments such as dust and oil stains;

2. Anti-rust treatment: use preservatives to smear key parts to prevent rust and corrosion;

3. Fasten the parts: fasten the screws at the joint to avoid loosening caused by vibration;

4. Functional test: regularly test whether all indicators meet the requirements (such as compressive strength and fatigue limit), and replace the aging and damaged parts in time when problems are found to avoid potential accidents.

In a word, as one of the basic links to ensure the normal operation of cold chain logistics, the tongue lock of railway freezer plays a vital supporting role. Only by strengthening management and maintenance can we ensure that they are always in good working conditions, further improve the level of railway freight service in China and promote the healthy and orderly progress of related industries!
