It solves the problem that the cars loaded on each section of the flat car cannot communicate with each other, and there are safety hazards in the fixed cars; the flat car is composed of the existing underframe, bogie, and brake , coupler buffer device, and ropes, four car wheel locking devices are installed on the underframe, and passing platforms are installed at both ends of the underframe. Because of the car wheel locking device, the car wheels are locked firmly, will not loosen, safe and reliable, can realize road-rail-road long-distance transportation without unloading, reduce road transportation distance, and save transportation costs.

Description

Flatcar

Technical field: the invention of the present invention is to improve the structure of the used flat car for railway transportation, especially to install a device capable of locking the car on the bottom frame of the flat car.

Background technology: At present, the flat cars used in railway transportation can only be hoisted and unloaded when transporting cars, and the fixed cars are tightened with ropes and/or chocks are used to plug the wheels of the cars. Blocks will be loose and prone to failure; the cars carried on each flat car cannot pass into the front or rear flat car, which brings stability to transportation and loading and unloading.

Summary of the invention: The purpose of this invention is to provide a flat car with a turntable, which can be used in conjunction with a flat car with a turntable, can transition to the front or rear flat car on a flat car, and can lock the wheels of the car on the flat car. Flat car; the purpose of the present invention is achieved through the following technical solutions: comprising vehicle underframe, bogie, braking device, coupler buffer device, fixed rope, bogie is installed under the two ends of vehicle underframe, vehicle coupler The buffer device is installed under the middle part of both ends of the underframe, the brake device is installed under the underframe and connected with the brake shoes, and is installed at the front and rear of the two sides of the underframe with ropes. Four automobile wheel locking devices are installed on the underframe, two of which are a group, and each group is installed symmetrically on the vertical central axis, and a passing platform is installed at both ends of the underframe.

Automobile wheel locking device: composed of steering box, cover plate, lead screw, slider, clamping body, rotating shaft, and box body; the steering box is installed in the middle of the box to make a cavity for installing the steering box, and the The left lead screw is installed in the box inner groove on the left side of the steering box, the right lead screw is installed in the box inner groove on the right side of the steering box, the inner ends of the two lead screws are connected with the steering box, and the slider is composed of On the lead screw, the clamping body components are installed on the box body through the rotating shaft, and the cover plate is installed on the box body between the clamping body components.

The advantages created by the invention: due to the adoption of passing platforms installed at both ends of the flat car, the car can move from one flat car to any one, which brings convenience to transportation and loading and unloading; realizes road-railway - Highway non-unloading connection transportation, reducing road transportation distance and transportation cost; because the car wheel locking device is installed on the underframe of the flat car to lock the car wheel, because of this mechanical locking device, no loosening will occur Phenomenon, so the car will not shift, will not break down, safe and reliable.

Fig. 2 is the structural representation of the undercarriage of flat car;

Fig. 3 is the structural representation of the automobile wheel locking device installed on the flat car;

Fig. 4 is a schematic diagram of the principle of the braking device system.

The specific embodiment: comprising undercarriage 4, bogie 2, braking device 3, coupler buffer device 1, fixed rope 5, automobile wheel locking device, constituted by a platform; bogie is installed under the two ends of undercarriage, The coupler buffer device is installed under the middle part of both ends of the underframe, the brake device is installed under the underframe and connected with the brake shoes, and is installed at the front and rear of the two sides of the underframe with ropes. Four automobile wheel locking devices 18 are installed on the undercarriage, and two are a group, and every group of vertical central axis is symmetrically installed, and the two ends of the undercarriage are installed through the platform 22.

Automobile wheel locking device: composed of steering box 19, cover plate 20, lead screw 16, slider 15, clamping body 14, rotating shaft 21, and box 13; the steering box is installed in the middle of the box to make an installation steering In the cavity of the box, install the left lead screw in the box inner groove on the left side of the steering box, install the right lead screw in the box inner groove on the right side of the steering box, and the inner ends of the two lead screws and the steering box Connection, the slide block is installed on the lead screw, the clamping body is installed on the box through the rotating shaft, and the cover plate is installed on the box between the clamping body.

Underframe: a frame structure composed of end beams 7, middle beams 10, side beams 8, corbels 9, large beams 11 and floor 12. The structure of the underframe is in the prior art, and various beams are made of section steel. The steel is made of 09CuPCrNi-A atmospheric corrosion-resistant steel with a yield strength of not less than 345Mpa. The steel castings used in the chassis are all made of AAR M-201B grade cast steel. space, effectively reducing the height of the vehicle's center of gravity, and improving the stability of the vehicle's operation.

Passing platform: It is placed flat when in use, and turned upright by 90 degrees when not in use. The passing platform is composed of a long frame and a flat steel plate.

The brake device is a Knorr-Bremse air brake system device that meets the UIC standard, including a KE control valve, a 12″ brake cylinder, a set of DRV600TH type two-way brake shoe clearance automatic adjuster, angled plug, stainless steel Line, NSW hand brake.
