Description

Railway flatcar underframe

Technical Field

The utility model relates to a chassis, especially a railway flatcar chassis.

Background

Railway flatcars have been an important tool for the remote transportation (maneuvering) of vehicles (equipment), and currently there are side-station trolleys for unloading equipment at a station, but they are not suitable for use in a field environment. If under the field environment, when running into the railway damage, the train trouble can't continue to travel and need implement the uninstallation, the people utilizes the rail sleeper to build temporarily usually, expends time, expends the manpower, and interim platform is insecure, fragile, and the present cab apron of building area is big, accomodates and uses inconveniently. Therefore, a technology needs to be improved, and the temporary side platform can be set up quickly in an emergency under the field environment, so that the field quick unloading of various crawler-type and wheeled vehicles can be implemented.

Disclosure of Invention

The purpose of the invention is as follows: the to-be-solved technical problem of the utility model is to provide a railway flatcar chassis, the inconvenient problem of vehicle uninstallation under the solution field environment improves and builds speed, realizes uninstallation fast, has reduced the parking space of materials such as cab apron, facilitates the use and carries to guarantee that the cab apron can firmly bear the equipment of big weight.

The technical scheme is as follows: railway flatcar chassis, including upper chassis, lower floor's chassis and cab apron, lower floor's chassis supports upper chassis, and lower floor's chassis is provided with the recess of placing the cab apron, lays the slide rail along chassis width direction in the recess, and the cab apron can slide on the slide rail, and the cab apron can fold and expand, folds when drawing in and places, expandes to 180 degrees when taking out.

Furthermore, storage boxes are further arranged on two sides of the lower-layer underframe, steel frames are placed in the storage boxes, and the steel frames are supported at the folding hinged positions of the cab apron when the cab apron is unfolded.

Further, the automobile chassis assembly further comprises a gasket, wherein the gasket is placed in the storage box, and when the automobile is unloaded, the gasket is filled to the position, adjacent to the upper end of the cab apron and the upper-layer chassis.

Further, the cab apron is 4.

Furthermore, the ferry plate upper surface is provided with anti-skidding edges and ribs, and the lower surface is provided with reinforcing ribs.

Has the advantages that: the utility model has the advantages of it is following:

(1) the underframe is matched with a railway flat car, meets the requirement of rapid unloading in a field environment in the railway transportation process of the car, and has the characteristics of convenient movement, large bearing capacity, simple operation, convenient use and maintenance and the like;

(2) the cab apron of the underframe adopts a folding structure, so that the occupied space at ordinary times is reduced, the steel frame support is arranged at the folding position of the cab apron when the underframe is unfolded, the bearing load is improved, and 80 tons of equipment can be borne in actual use to the maximum extent;

(3) the storage box and the groove are arranged in the bottom frame, so that the carrying and the use are convenient, and the work is quick and efficient.

Detailed Description

As shown in fig. 1 and 2, the underframe of the railway flatcar in the present embodiment includes an upper underframe 1, a lower underframe 2, and a cab apron 3. The upper-layer chassis 1 is used for parking vehicles, wood floors are laid on the upper surface of the upper-layer chassis, and reinforcing ribs and supporting seats are welded on the lower surface of the upper-layer chassis. The lower-layer underframe 2 is used for supporting the upper-layer underframe 1, placing the cab apron, placing the supporting steel frame, connecting wheels of the railway flat car, a buffer device, a brake device and the like. The number of the grooves for placing the cab apron 3 in the lower-layer chassis 2 is 4, the slide rails 4 which are convenient for taking out the cab apron 3 are arranged in the grooves, the number of the cab apron 3 is four, the cab apron can be folded to reduce the occupied space, the cab apron can be unfolded to 180 degrees during use, and the unfolded state is shown in figure 3. The ferry plate 3 may also be folded several times to further reduce the footprint. The upper surface of the cab apron 3 is provided with anti-skid ribs 6, the lower surface is provided with reinforcing ribs, and the upper end of the cab apron can be clamped in grooves in the side surface of the lower-layer chassis 2 after being unfolded, so that fixation is realized. The space between the ferry plates after being unfolded can be properly adjusted according to the width of the track or the tire, and is generally not larger than the width 1/2 of the track or the tire, and the size of the ferry plate can be adjusted according to the type of the flat car, so that the railway transport needs are met. As shown in figures 4 and 5, when the cab apron 3 is unfolded for use, the middle hinged part is supported by a steel frame 7 to increase the bearing load, so that the cab apron is suitable for use of heavy equipment. The both sides of lower floor's chassis 2 have the storage tank 5 of placing strutting arrangement, and storage tank 5 is used for depositing steelframe 7, gasket etc..

In the transportation process, the cab apron is folded and placed in the groove of the lower-layer underframe. When the chassis is unfolded, the cab apron moves along the slide rail to extend out, two planes of the cab apron form 180 degrees after the cab apron is unfolded, the top end of the cab apron is fixed in the groove on the side surface of the chassis, and the bottom end of the cab apron is arranged on the ground. When the field vehicle needs to be unloaded, the cab apron is unfolded, the central joint of the cab apron can be supported by a steel frame, and 2-3 steel frames can be used according to the mass of the loaded and unloaded vehicle. The steel frame is placed in the lower-layer underframe storage box at ordinary times. When the vehicle is unloaded, the gasket can be used for being filled at the upper end of the cab apron and adjacent to the upper underframe, so that the vehicle is prevented from being extruded and deformed on the side edge of the upper underframe.
