Description

Technical Field

[0001] This invention relates to the field of railway freight car technology, and more specifically to the field of longitudinal beam technology for a full-length loading opening for aluminum alloy car roofs. Background Technology

[0002] Most grain hopper trucks currently use an all-steel welded structure for their roofs. To ensure the connection between the longitudinal beams and various components such as the roof panel and partition columns, the longitudinal beams of the loading opening on the roof are formed by combining multiple bent parts.

[0003] The patent with publication number CN119389257A and patent name "A Roof Structure for a Railway Covered Hopper Car" discloses the following: A roof structure for a railway covered hopper car, relating to the field of transportation equipment technology, includes a fixed roof assembly and a movable roof assembly disposed on the fixed roof assembly; the fixed roof assembly includes an arc-shaped frame, a top plate disposed on the arc-shaped frame, and a longitudinal loading port frame disposed longitudinally in the middle of the top plate; the movable roof assembly includes a square loading port cover assembly, a circular top cover plate assembly, a top cover support, a top cover crossbeam assembly, a top cover longitudinal beam assembly, and a circular loading port locking device; the square loading port cover assembly is sealed at the longitudinal loading port frame and its translation is achieved by pneumatic control; the square loading port cover assembly has multiple circular loading ports; the circular top cover plate assembly is sealed at the circular loading ports; and each circular top cover plate assembly is provided with a circular loading port locking device. This invention employs a double-layered top cover and multiple feed inlets, which solves the technical problem of top cover movement jamming when the sliding track is deformed or the roller bearing is corroded.

[0004] Due to limitations in the bending process, the longitudinal beams of the aforementioned patents are segmented and extended in the longitudinal direction. The all-steel longitudinal beams have a complex structure, are heavy, and require a large amount of welding work, making them unsuitable for all-aluminum alloy roofs. Summary of the Invention

[0005] The purpose of this invention is to provide a longitudinal beam for a continuous loading opening on an aluminum alloy vehicle roof in order to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention specifically adopts the following technical solution: This invention provides a longitudinal beam for a full-length loading opening on an aluminum alloy vehicle roof, comprising a left elevation, a right elevation, a lower plane, an upper plane, and a middle plane; the left elevation, right elevation, lower plane, upper plane, and middle plane are all made of aluminum alloy, and the thicknesses of the left elevation, right elevation, lower plane, upper plane, and middle plane are different. The left and right facades are vertically aligned with their bottoms flush, and the left facade is taller than the right facade. One end of the middle plane is connected to the middle of the left facade, and the other end is connected to the top of the right facade. The lower plane is connected to the bottom of the left and right facades, and the upper plane is horizontally positioned at the top of the left facade.

[0007] Specifically, the left facade serves as the side wall of the roof loading opening, while the right facade connects to the roof to form an arched rib. The lower plane connects to the columns in the partition wall, with the rivets protruding into the profile cavity for localized reinforcement. Different wall thicknesses are designed at various points to meet functional requirements and reduce weight. Closed-end extruded profiles can be manufactured in a single piece according to the vehicle's length, eliminating the need for splicing.

[0008] In one embodiment, the left elevation, right elevation, lower plane, and middle plane constitute the inner cavity of the longitudinal beam; it also includes a reinforcing rib, which is vertically arranged in the middle of the inner cavity of the longitudinal beam, and the upper and lower ends of the reinforcing rib are respectively connected to the middle plane and the lower plane.

[0009] Specifically, a vertical reinforcing rib is provided in the center of the longitudinal beam cavity of the loading port longitudinal beam to increase the strength of the longitudinal beam.

[0010] In one embodiment, the middle plane is a sloping structure, and the height of the middle plane connecting to the left facade is higher than the height of the middle plane connecting to the right facade.

[0011] Specifically, the height of the connection between the middle plane and the left facade is higher than the height of the connection with the right facade. This structural design facilitates drainage.

[0012] In one embodiment, the portion of the middle plane near the right facade is provided with a step for connection to the roof panel.

[0013] In one embodiment, the upper surface is used to connect and install the roof sealing strip, the horizontal width of the upper surface is smaller than the horizontal width of the lower surface, and a downward mounting protrusion is provided on the right edge of the upper surface.

[0014] Specifically, the downward protrusions facilitate extrusion molding.

[0015] In one embodiment, local reinforcing surfaces are superimposed on the upper surfaces of the lower planes on both sides of the reinforcing rib, and each local reinforcing surface is provided with a connection hole for connecting to the partition wall column.

[0016] Specifically, the rivets connecting to the columns protrude into the inner cavity of the longitudinal beams for local reinforcement.

[0017] In one embodiment, the left facade, right facade, lower plane, and upper plane are all made of aluminum alloy, and the left facade, right facade, lower plane, and upper plane are closed-end aluminum alloy extruded profiles.

[0018] Specifically, the longitudinal beams of the loading hatch are made of closed-end aluminum alloy extruded profiles and are used as the frame of the roof.

[0019] Closed-end aluminum alloy extruded profiles have the advantages of being lightweight and having high strength.

[0020] In one embodiment, the junctions of the left elevation, right elevation, lower plane, upper plane, and middle plane are all provided with rounded corners.

[0021] Specifically, the rounded corners between the surfaces facilitate molding.

[0022] In one embodiment, the upper surface of the upper plane is provided with mounting holes for connecting and installing roof sealing strips.

[0023] The beneficial effects of the present invention are as follows: 1. This invention patent proposes a longitudinal beam for a continuous loading opening on an aluminum alloy vehicle roof. It is made of aluminum alloy extruded profiles, which are lightweight. One longitudinal beam can meet the connection requirements of different components. The extruded profiles can be made into a continuous structure according to the length of the vehicle, eliminating the trouble of splicing and extending, and has significant economic benefits.

[0024] 2. The left elevation of the longitudinal beam of the loading port is used as the side wall of the loading port on the roof, the right elevation is used to connect the roof to form an arc-shaped stiffening plate, the lower plane is used to connect the column in the partition wall, the upper plane is used to connect and install the roof sealing strip, and the middle plane is used to connect the roof panel.

[0025] 3. A vertical reinforcing rib is provided in the center of the inner cavity of the longitudinal beam of the loading port to increase the strength of the longitudinal beam.

[0026] 4. The height of the connection between the middle plane and the left facade is higher than the height of the connection with the right facade. This structural design facilitates drainage. Attached Figure Description
