Description

Multifunctional flat car body

Technical field

The invention relates to a multifunctional railway freight flat car body, which belongs to the technical field of railway transportation.

Background technique

Traditional railway flat cars are divided into container-specific flat cars and general-purpose flat cars. General-purpose flat cars can transport containers, as well as timber, large construction machinery, wheeled vehicles, rail platoons, and large building materials. Some railway flat cars have reversible end walls for transporting bulk goods, but the end walls are not easy to disassemble, which affects transportation efficiency.

For the need to switch transportation of multiple goods, especially when transporting on subway lines, users do not have much demand for flat cars. Traditional railway flat cars can no longer meet all the requirements of users. Therefore, it is necessary to develop a variety of transportation functions. The flat cars can improve transportation efficiency and save costs.

Although a new type of railway multifunctional flat car is disclosed in the patent CN201811444844, the flat car has the following problems when in use:

1. The container lock of this flat car is welded inside the side beam, and it is not convenient for the operator to operate and observe whether the container lock is installed in place. At the same time, the fatigue analysis result of the underframe structure near the container lock cannot meet the requirements of BS7608;

2. After the side wall of the movable end of the flat car is deformed, it is not conducive to maintenance and disassembly;

3. The rail row limit device of the flat car is lifted by the container corner pieces at both ends, and the lifting at both ends cannot completely guarantee that the limit device is level after being lifted, and twisting may occur, which affects the installation efficiency. At the same time, the handle of the column is inserted It may be mistaken as a lifting point, causing misoperation and affecting safety.

Summary of the invention

In order to solve the technical problems existing in the prior art, the present invention discloses a multifunctional transport flat car body, which can transport timber, containers, large machinery, rail platoons, bulk goods and the like.

The multifunctional transport flat car body provided by the present invention is realized through the following technical solutions.

The body of the multifunctional flat car disclosed by the present invention is mainly composed of an underframe, a container locking device, a rail row limiting device or a movable end side wall; the underframe includes end beams, traction beams, bolster beams, and middle beams , Side beams, small beams, large beams and floors;

The container locking device adopts a lifting lock, which is installed on the outside of the side beam of the underframe;

The movable end side wall is installed on the bottom frame, which includes a side wall and an end wall, a support is installed on the upper part of the outer side of the side wall, and a base and a column insert are installed on the side beam of the bottom frame. The bottom of the column is inserted into the base, the top is inserted into the support, and the movable end side wall is installed on the base frame;

The rail row limiting device includes a base and two post inserts. The base is provided with holes with different pitches, and the holes are matched with the two post inserts; each post insert is connected to the base through a connecting device, Prevent the column plug from accidentally falling off when the vehicle is running empty.

As a further technical solution, the connecting device includes a chain, a round pin, a lock head and an end head;

The chain is fixed on the base by bolts, one end of the round pin is fixed with an end, the end is an eccentric structure, the other end of the round pin is provided with a slot, and a rotating pin is arranged in the slot, and the lock is rotatably connected with the rotating pin , The axis of the lock head and the axis of the round pin are arranged at an included angle; the lock head can contact with the bottom groove surface of the slot to limit the rotation of the lock head in the slot, so that the lock head can only rotate within the set range of angles, Adjust the angle of the lock head so that the axis of the lock head can always maintain a certain angle with the axis of the round pin.

As a further technical solution, a handle is provided on the side of the column insert.

As a further technical solution, inclined plates are provided at both ends of the column insert.

As a further technical solution, an oval hole is provided on the base and the column insert, and the round pin is inserted into the oval hole.

As a further technical solution, lifting lugs are provided at both ends of the base.

The beneficial effects of the present invention:

1. The container lock is welded to the side beams, which shortens the overall width of the underframe. The fatigue analysis results of the underframe can meet the requirements of BS7608. Compared with the previous structural stress concentration point near the container lock, the underframe is stressed. It is more uniform, and it is more convenient for personnel to operate the container lock;

2. The side wall structure of the movable end is based on the new requirements of the user. A base and a column insert are added to the side beam of the underframe, and a support is added to the side wall. The movable side is realized through the cooperation of the column pin and the support and the base. The wall structure is fixed; at the same time, when the column insert is used alone, it can transport goods such as rails to prevent it from falling off;

3. The optimized design of the rail row limit device is that the base and the post are connected by the connecting device designed in this application. Specifically, the oval hole of the base and the post is connected with a round pin, and one end of the round pin has a rotatable lock. The other end of the round pin has an end, and the end is in contact with the base, and the movable pin cannot rotate. When the lock head is perpendicular to the axis of the round pin, the lock head can contact the outer surface of the bracket base, and then work together with the end to prevent rounding. The pin is separated from the base of the bracket to ensure the insertion strength of the pin; it can prevent the pin from accidentally falling off when the vehicle is running; the end of the round pin is an eccentric structure, after installation, it has its own anti-falling effect, and the round pin can only be removed manually And chain.

4. There are four lifting lugs on the base of the rail row limit device, which can be used to lift the column insert and the base at the same time through the column insertion, or the base can be lifted separately, which is more convenient for operation.
