Description

Technical Field

[0001] The utility model relates to the technical field of milling machine auxiliary tools, and more specifically to the technical field of a hopper car side wall with a hybrid arc and straight line Background Technique

[0002] Hopper cars can be divided into two types in terms of their structures: covered and uncovered. Railway hopper cars are all covered and uncovered hopper cars for transporting cold materials. For the needs of production in metallurgical and coking enterprises, there are also hopper cars for transporting hot materials, such as coke quenching cars, hot sintered ore cars, hopper weighing cars, etc. Regardless of the type of unloading hopper car, their common feature is that in order to make the goods slide down by their own weight for unloading, a hopper plate with a certain inclination angle to the horizontal is provided inside the car body, and the unloading door is arranged at the bottom or side of the car body. The following technologies regarding the hopper car side wall are disclosed in existing patents:

[0003] The patent with the publication number CN117181931A and the patent name "A Hopper Car Side Wall Closing Device and Hopper Car Side Wall Equipment" discloses the following content: A hopper car side wall closing device and hopper car side wall equipment. An embodiment of the present application provides a hopper car side wall closing device, including a lifting member and a closing mechanism. The lifting member is used to lift the closing mechanism, and the closing mechanism includes a main body and a driving component. The main body has a first end and a second end. The first end of the main body is supported on the hopper ridge partition board, and the second end is arranged above the upper side beam; the driving component is arranged at the second end of the main body, and the driving end of the driving component contacts the upper side beam; the driving component can drive the upper side beam to move towards the direction close to the hopper ridge partition board, so that the other side of the side wall plate fits the arc surface, that is, only by assembling the hopper car side wall closing device to the hopper car side wall and starting the driving component, the closing of the side wall plate can be realized, without pre-bending the side wall plate in advance or using a jack for closing, with simple operation, low labor intensity, and no safety hazards, greatly improving the production efficiency.

[0004] The patent with the publication number CN103909941A and the patent name "Side Wall Structure of Hopper Car" discloses the following content: A side wall structure of a hopper car, including: an integrally formed upper side beam, an integrated side wall plate, an integrally formed lower side beam and a lower side wall; the upper side beam is riveted to the integrated side wall plate below; the side wall plate is riveted to the integrally formed lower side beam below; the side wall plate is a plate-column structure with an integrated wall board and side columns, and the side columns are arranged inside the car body; the lower side beam is riveted to the lower side wall below. The side wall structure of the hopper car provided by the utility model, the side wall plate with the integrally built-in side columns not only avoids the reduction of its own strength due to the rivet holes, but also avoids the increased weight and cost caused by the use of rivets, and because the side columns are built-in, the space between the side columns can be utilized, thereby increasing the volume of the car body.

[0005] Combined with the above patents, there are basically two forms of the side wall assembly of hopper cars in China at present. One is the straight wall type, and the other is the arc type. The straight wall side wall can make greater use of the clearance space and increase the vehicle volume. However, the stiffness of the side wall panel is insufficient, and it is easy to produce outward bulging deformation after loading goods, which is not convenient for subsequent vehicle maintenance and use. The arc side wall has better stiffness than the straight wall side wall, but it cannot make full use of the clearance space, and the vehicle volume is small, which is not conducive to the subsequent operation of the vehicle.

[0006] Therefore, it is necessary to study a new type of side wall structure that can not only make full use of the clearance space but also ensure the stiffness of the side wall. Summary of the Invention

[0007] The purpose of the present invention is to provide a hopper car side wall of a hybrid arc and straight line type to solve the technical problem that the existing side wall of the hopper car cannot take into account both making full use of the clearance space and strength.

[0008] The present invention specifically adopts the following technical solutions to achieve the above purpose:

[0010] The end of the strengthening beam is connected to the first partition wall assembly, the second partition wall assembly or the end side wall connecting plate.

[0011] In one embodiment, several installation beam assemblies are arranged between the two side wall panels.

[0012] In one embodiment, the end side wall connecting plates are obliquely arranged at both ends of the side wall panel at a certain angle (the position where the end wall panel is vertically connected to the side wall panel) to prevent goods from accumulating at this position and improve the unloading rate of goods.

[0013] In one embodiment, it further includes an upper side beam, which is attached to the upper edge of the side wall panel, and the upper parts of the first partition wall assembly and the second partition wall assembly are both connected to the upper side beam.

[0014] Specifically, the connection position between the side wall panel and the upper side beam adopts a straight line form, which is convenient for process assembly and fixing construction.

[0015] In one embodiment, the cross-section of the side wall panel includes a middle straight segment, an upper straight segment, and a lower straight segment.

The bottom of the lower straight segment is connected to the funnel assembly in a straight segment form.

[0016] In one embodiment, an upper arc segment for increasing the self-rigidity of the side wall panel and having a radius greater than one meter is provided between the middle straight segment and the upper straight segment; a lower arc segment for increasing the self-rigidity of the side wall panel and having a radius greater than four meters is provided between the middle straight segment and the lower straight segment.

[0017] Specifically, the middle part of the side wall panel is in a straight form, and an arc with a radius greater than one meter is used for connecting and transitioning between the middle and the upper part to increase the self-rigidity of the side wall panel. The lower part of the side wall panel is in a straight form and is connected to the underframe and the funnel, which is convenient for assembly and construction. An arc with a radius greater than four meters is used for connecting and transitioning between the middle and the lower part, which not only improves the self-rigidity of the side wall panel but also can make full use of the characteristics of the upper fold, middle straight, and lower fold presented by the clearance section, fits the clearance outline to the greatest extent, and increases the vehicle volume.

[0018] In one embodiment, the second partition wall assembly includes two symmetrically arranged partition wall panels, support columns provided on the corresponding partition wall panels, an upper connecting beam connected to the upper parts of the two support columns, and a lower connecting beam connected to the lower parts of the two support columns;

[0019] Insertion grooves for inserting the partition wall panels are provided on the support columns, and the shape of the connection between the partition wall panel and the side wall panel is the same as the shape of the side wall panel.

[0020] Specifically, the partition wall panel is used to support the side wall panel, divide the area for the goods, and reduce the impact of the goods inside the vehicle body.

[0021] In one embodiment, the second partition wall assembly further includes at least two columns provided on the top of the upper connecting beam, and at least one rib plate is provided between each column and the upper connecting beam.

[0024] The beneficial effects of the present utility model are as follows:

[0025] 1. A number of partition wall components, mounting beam components and strengthening beams are arranged between the side walls. While improving the anti-outward expansion deformation ability of the side walls, the thickness of the plates of each component can be minimized as much as possible, realizing the lightweight design of the vehicle.

[0026] 2. A number of strengthening beams uniformly arranged longitudinally along the side wall plates can effectively solve the problems of structural instability and deformation that may occur when the vehicle is longitudinally impacted.

[0027] 3. The adoption of an L-shaped upper side beam can not only reduce the vehicle's own weight, but also reduce the interior volume of the vehicle occupied by the special-shaped upper side beam, increasing the overall volume of the vehicle.

[0028] 4. The side wall plates adopt a combination form of arc and straight line in the cross section, with the upper, middle and lower parts being straight lines, making the maximum use of the locomotive and vehicle clearance. The straight lines are connected and transitioned by two arcs with different radii, increasing the stiffness of the side wall plates themselves and at the same time increasing the vehicle volume.
