Description

A gondola with low load surface and high net unloading rate Technical Field

[0001] The invention belongs to the technical field of gondola cars, and in particular relates to a gondola car with a low load-bearing surface and a high net unloading rate. Background Art

[0002] As the main type of railway freight car, open wagons play a vital role in global rail transportation. They are mainly used to transport bulk cargo such as coal and ore. The quality of open wagons determines whether rail transportation can operate safely and quickly. Factors affecting open wagon quality mainly include the performance of the open wagon and its own condition. At present, domestic open wagon loading and unloading equipment mainly includes forklifts, cranes, and dumpers. When open wagons are used with excavation equipment such as forklifts and cranes, the blind spots in the operator's field of vision can easily cause damage to the open wagon's side walls and door panels, posing a safety hazard. Therefore, the use of dumpers to unload open wagons has gradually become the future development direction.

[0003] However, unloading cargo using a dumper presents three challenges: First, the vehicle's height is limited by the impact of the dumper, which in turn affects the vehicle's capacity. Second, cargo easily accumulates inside the vehicle, corroding the wall panels and floor, thus reducing the vehicle's service life. Third, there are two main connection methods between the existing side walls and the chassis: welding and riveting. However, riveting is not only costly but also requires specialized riveting tools. When welding, the side walls need to be attached to the outside of the chassis, and when the dumper's pressure acts on the top of the vehicle, the root weld is prone to cracking.

[0004] Summary of the Invention

[0005] In order to solve the above problems existing in the prior art, the object of the present invention is to provide an open car with a low load-bearing surface and a high unloading rate.

[0016] As a preferred solution of the present invention, the end wall panels are connected with end transverse bands, and the ends of the end transverse bands are connected to the side walls.

[0017] As a preferred solution of the present invention, the bottom of the inner side of the end wall panel is connected to a circular arc plate, and the lower end of the circular arc plate is connected to the base frame.

DETAILED DESCRIPTION

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. It should be noted that the embodiments of the present invention and the features therein may be combined with each other unless there is a conflict.

[0033] As shown in Figures 1 to 7, the open car with low load-bearing surface and high unloading rate of this embodiment includes a chassis assembly 1, the front and rear sides of the chassis assembly 1 are respectively connected to a side wall assembly 2, the left and right sides of the chassis assembly 1 are respectively connected to an end wall assembly 3, the two side wall assemblies 2 and the two end wall assemblies 3 are connected in sequence, the bottom of the chassis assembly 1 is a concave bottom structure with high front and rear sides and low middle, the front and rear sides of the inner wall of the chassis assembly 1 are arc structures, and the side wall assembly 2 is vertically located on the chassis assembly 1.

[0034] The bottom of the chassis component 1 of the present invention is a concave bottom structure with high front and rear sides and low middle, which can achieve the goal of reducing the vehicle's load-bearing surface and increasing capacity. The front and rear sides of the inner wall of the chassis component 1 are arc structures, which can achieve the goal of reducing cargo residue and high unloading rate. The side wall component 2 is vertically located on the chassis component 1 to avoid the problem of cracking of the root welds of the side columns 2.3 caused by excessive pressure from the tipping machine. The two side wall components 2 and the two end wall components 3 form an annular frame structure, and reinforcement measures such as support rods and reinforcement seats are no longer provided inside. Not only does it achieve the goal of improving the vehicle's resistance to external expansion and impact, but it can also ensure that the interior of the vehicle body is flat and smooth, and the unloading rate is high.

[0035] Specifically, as shown in Figures 2 and 3, the base frame assembly 1 includes a central beam 1.1, to which a plurality of cross beams 1.2 are connected. A floor 1.3 is arranged above the central beam 1.1 and the plurality of cross beams 1.2. The cross beam 1.2 is a concave bottom structure with high front and rear sides and low middle. The side columns 2.3 of the side wall assembly 2 are vertically located on the cross beam 1.2. The front and rear sides of the floor 1.3 are arc structures. The floor 1.3 is respectively connected to the side wall panels 2.2 of the side wall assembly 2 and the end wall panels 3.3 of the end wall assembly 3.

[0036] The chassis component 1 is the main load-bearing structure of the vehicle and adopts a fishbone type. The center beam 1.1 is its main trunk. The center beam 1.1 can be made of steel sections or plates welded together to bear the longitudinal and vertical forces of the vehicle. The cross beam 1.2 is its branch and adopts a bathtub-shaped concave bottom structure with high sides and low middle. The cross beam 1.2 can be set as a box-type structure with double webs as needed, or it can adopt an I-beam with a single web. The cross beam 1.2 is used to assist the center beam 1.1 in bearing. The two sides of the floor 1.3 are bent upward to form an arc structure, which overlaps with the side wall panels 2.2. This not only keeps the welds away from the floor 1.3 surface and reduces the corrosion of the welds by accumulated water, but also the arc structure can avoid cargo accumulation and improve the net unloading rate of cargo.

[0037] Specifically, as shown in Figures 4 and 5 , the side wall assembly 2 includes an upper side beam 2.1, below which is connected an inclined side wall panel 2.2. Several side columns 2.3 are connected to the side wall panel 2.2. The side columns 2.3 are seated on the cross beam 1.2 of the base frame assembly 1. The bottom of the side wall panel 2.2 is connected to the floor 1.3 of the base frame assembly 1. The ends of the side wall panel 2.2 are connected to the end wall panels 3.3 of the end wall assembly 3. The ends of the upper side beam 2.1 are respectively connected to the upper end beams 3.2 of the end wall assembly 3. Several side cross straps 2.4 are connected between the side walls, and the ends of the side cross straps 2.4 are connected to the end cross straps 3.1 of the end wall assembly 3.

[0038] The side wall component 2 is a grid-like plate-column structure. The upper side beam 2.1 is a special-shaped five-sided closed structural beam, which can prevent cargo from piling up while being able to change its shape arbitrarily according to external limit requirements to increase the vehicle volume. The side wall panel 2.2 is formed by bending a plate with an angle to meet the requirements of high unloading efficiency. The side wall panel 2.2 extends outward in a "king" shape at the side transverse strip 2.4 to ensure the connection strength between the side transverse strip 2.4 and the end transverse strip 3.1. Several side columns 2.3 are welded in parallel on the outside of the side wall panel 2.2. The side columns 2.3 are formed by bending the plate into a variable-section trough structure. The side columns 2.3 can have different cross-sections at different positions based on the equal strength design concept. The side columns 2.3 are vertically located above each cross beam 1.2. The side columns 2.3 are connected by a side transverse strip 2.4 to improve the vehicle's resistance to external expansion and ensure the stability of the vehicle body under various working conditions.

[0039] Specifically, as shown in Figures 6 and 7, the end wall assembly 3 includes an upper end beam 3.2, an end wall panel 3.3 connected below the upper end beam 3.2, an end column 3.5 connected to the end wall panel 3.3, the bottom of the end wall panel 3.3 connected to the floor 1.3 of the base frame assembly 1, the end column 3.5 located on the center beam 1.1 of the base frame assembly 1, the end of the end wall panel 3.3 connected to the side wall panel 2.2 of the side wall assembly 2, and the end of the upper end beam 3.2 connected to the upper end beam 3.2 of the side wall assembly 2. The end wall panel 3.3 is connected to an end cross band 3.1, the end of the end cross band 3.1 connected to the side cross band 2.4 of the side wall assembly 2. The inner bottom of the end wall panel 3.3 is connected to a circular arc plate 3.4, the lower end of the circular arc plate 3.4 connected to the floor 1.3 of the base frame assembly 1.

[0040] The end wall component 3 is a plate-column structure, and the end transverse strip 3.1 is a trough-type structure, and its height direction is consistent with the side transverse strip 2.4. The upper end beam 3.2 is made of a rectangular tube bent, and its height direction is consistent with the upper side beam 2.1. The above two methods ensure that the vehicle forms a closed frame structure in the circumferential direction, thereby improving the vehicle's resistance to external expansion and impact. The end wall panel 3.3 is a CNC-cut straight plate. In order to reduce cargo residue, an arc plate 3.4 is provided at the intersection of the end wall panel 3.3 and the floor 1.3. The end column 3.5 is a through-type trough-type beam, which together with the end transverse strip 3.1 improves the vehicle's impact resistance.

[0041] The present invention is not limited to the above-mentioned optional implementation modes. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that falls within the scope defined by the claims of the present invention falls within the scope of protection of the present invention.
