Problems solved by technology

The disadvantages are: 1. The transition angle of the bending part is large, which is not suitable for self-wheel loading and unloading of vehicles; 2. The combination of center and side beams is used for carrying, and the arrangement of the carrying mode is unreasonable when loading vehicles with wide wheelbases such as spare parts vehicles; 3. . Fully enclosed overall load-carrying, no braking device can be arranged in the middle of the car body; 4. No anti-skid device, tool storage device and other equipment, not suitable for loading and transportation of special vehicles

Embodiment 1

[0026] A flat car with a concave bottom, its composition includes: a concave bottom frame 3, the two ends of the concave bottom frame are connected to the coupler buffer device 1 and the end turning device 7, and a hand brake is installed on one end of the concave bottom frame Device 2, the two ends of the lower part of the concave underframe are connected to the bogie 4, the middle and lower part of the concave underframe is equipped with an air brake device 5, and the concave underframe is connected to the middle storage device 6. The coupler buffer device is installed at both ends of the concave underframe, which is used to connect with other railway wagons and transmit the longitudinal impact force; the hand brake device is installed at one end of the concave underframe to realize the human braking of the vehicle; the bogie is installed on the concave bottom The lower part of the frame end is used to transmit the vertical load and make the vehicle run on the track; the air ...

Embodiment 2

[0028] For the flat car with a concave bottom, the concave bottom frame includes two measuring beams 8, the side beams are a concave curved structure in the middle, and the two side beams are connected by a cross beam 9. The two ends of the side beam are vertically connected to the corbel 10, the corbel is connected to the bogie, the corbel is connected to the cross beam to the traction beam 11, and the traction beam is buffered to the coupler The device is connected, and the side beam is connected to the floor 12 on the cross beam. The side beam is the main bearing part of the concave chassis; the corbel is perpendicular to the side beam and welded on the side beam along the lateral direction of the car body, and is used to connect with the bogie; the traction beam is located at both ends of the concave chassis, and is welded with the cross beam and the corbel , used to install the coupler buffer device; the cross beam is arranged laterally along the car body to connect the s...

Embodiment 3

[0030] For the flat car with a concave bottom, the end turning device includes an end plate 13, the end plate is connected to a hinge 14, and the hinge is connected to a stopper 16 through a pin 15. The end plate and the hinge group are welded together; the hinge and the retaining iron are connected together with a pin, which is used to make the end plate rotate along the pin; the retaining iron is used to lock the end plate when it stands up; the bracket 18 is welded on On the concave chassis, it is used to support the end plate when the end plate is flush with the end force of the concave chassis.

Abstract

The invention relates to a depressed center flat car. A middle beam, a side beam combination or a fully enclosed integral pattern is adopted by the vertical carrier beam of the existing depressed center flat car, cargoes are loaded uniformly in a carrying surface or two sides of a longitudinal central line of a car body, the curved beam of the carrier beam is concave-shaped, a transition angle of the curved part is mostly between 55 degree and 75 degree, and no slip devices and tool storage devices are arranged. The depressed center flat car invention comprises a concave-shaped chassis (3), wherein two end-tails of the concave-shaped chassis are connected with a car coupler damping device (1) and an end tilter (7), a hand brake device (2) is arranged on one end of the concave-shaped chassis, two ends of the lower part of the concave-shaped chassis are connected with a bogie (4), an air braking device (5) is arranged on the middle-lower part of the concave-shaped chassis, and the concave-shaped chassis is connected with a middle part storage device (6). The depressed center flat car is used for the railway transportation of special automobiles, such as shipping spare parts.

Description

Technical field: [0001] The invention relates to a special railway wagon for transporting special vehicles such as spare parts wagons, in particular to a flat wagon with a concave bottom. Background technique: [0002] Special vehicles such as spare parts vehicles are important equipment for transportation. They are used to transport large spare parts for maintenance and repair of various special vehicles. In order to quickly transport spare parts vehicles to designated locations, railway transportation is required. Due to the high body of the spare parts car, if it is shipped by general-purpose trucks, it will exceed the specification of GB / T146.1-1983 "Standard Gauge Railway Rolling Stock Limits", and for the convenience of loading and unloading, it is required that the spare parts car can be slowly driven to the loading vehicle. The location, therefore, required new railway wagons to meet the demand for spare parts car transportation. [0003] The general railway flat ca...
