detailed description

The present invention will be further described in detail below in conjunction with the drawings and embodiments.

Please refer to FIG. 3 and FIG. 4. FIG. 3 is a schematic perspective structural view of a railway wagon provided by the present invention in a specific embodiment; FIG. 4 is a perspective view of an end wall of a railway wagon provided by the present invention in a specific embodiment. Schematic.

In a specific embodiment, the railway wagon of the present invention is generally used for carrying bulk cargo, and may be a hopper car. For ease of unloading, the end wall may be inclined, as shown in Figures 3 and 4, at this time, the end The wall not only bears the vertical load of the bulk cargo in the car, but also bears the inertial impact load generated by the train starting, braking and the conditions of curve, ramp, acceleration and deceleration during the running of the vehicle.

The end wall used in the railway wagon of the present invention comprises a plurality of dividing wall panels 1 each extending in the up and down direction and connected in order from left to right; each of the dividing wall panels 1 comprises an inner side panel 11 connected to each other. And the outer side plate 12, and a hollow cavity 13 is formed between the inner side plate 11 and the outer side plate 12, and the rib 14 is provided in the middle cavity 13.

The fact that the inner side panel 11 and the outer side panel 12 extend in the up-and-down direction means that the inner side panel 11 and the outer side panel 12 extend substantially in the up-and-down direction, and may be inclined at a constant angle with respect to the vertical direction as long as the inner side panel 11 and the outer side panel 12 are up and down. It is sufficient that the direction has an extending tendency, and it is not limited to the inner side panel 11 and the outer side panel 12 extending vertically in the up and down direction.

In the prior art, the end wall panel 2 adopts a plate-column structure, and the end wall panel 2 is a thin plate. Therefore, in order to achieve a certain load-bearing capacity, a support beam structure such as a cross-belt and an end-column beam member must be disposed behind. The structure is complicated and the processing is difficult.

In view of the above problems, the present invention adopts the above-mentioned structural arrangement, the end wall comprises a plurality of partition wall panels 1, and each of the partition wall panels 1 is connected from left to right in sequence, and has a simple structure and is convenient for assembly; each of the partition wall panels 1 includes an inner side panel 11 and The outer side plate 12, and between the two side plates are provided with reinforcing ribs 14, canceling the branch The arrangement of the brace beam simplifies the structure, reduces the number of required parts, and reduces the manufacturing difficulty; the reinforcing rib 14 is arranged between the inner side plate 11 and the outer side plate 12 to form a closed box-shaped structure, from the structure From the mechanical point of view, the structure has a high bearing capacity, which in turn simplifies the end wall structure, improves the strength of the entire end wall, and maintains the original mechanical properties of the end wall.

The orientation described in this paper is based on the railway wagon, the direction of the running track near the railway wagon is lower, and the direction away from the running track is upward; the direction of the railway wagon is longitudinal, in a plane parallel to the running track, perpendicular to The longitudinal direction is the lateral direction; the lateral direction may also be referred to as the left-right direction, viewed in the running direction of the vehicle, the direction in the lateral left side is left, and the direction in the lateral direction is right; in all directions, near the railway wagon The direction of the center is inside, and the direction away from the center is outside.

Some of the numbers described herein are a plurality of uncertainties, usually greater than three.

Further, each of the wall panels 1 can also be extruded from a hollow aluminum profile. Since the partition wall panel 1 extends in the up and down direction, the hollow aluminum profiles can be extruded in the up and down direction to form the partition wall panel 1. The partition wall panel 1 includes an inner side panel 11, an outer side panel 12, and a reinforcing rib 14 disposed therebetween, and the three can be extruded by a hollow aluminum profile to form a closed box type partition wall panel 1.

Since the mold used for the extrusion molding of the hollow aluminum profile generally has a uniform width, the length direction thereof is basically not limited. When the partition wall panel 1 is formed by pressing the hollow aluminum profile in the up and down direction, it is convenient to control the partition wall panel 1 in the left and right directions. The width in the direction increases the machining allowance in the up and down direction, so as to increase or decrease the height of the end wall according to the height requirement of the vehicle body, and optimize the structure of the vehicle body.

At the same time, the entire end wall is extruded with hollow aluminum profiles, which reduces the number of parts on the end wall, simplifies the manufacturing process, reduces the manufacturing difficulty, and helps shorten the production cycle of the product; more importantly, the hollow aluminum profile The cross-sectional shape and size can be flexibly adjusted. By optimizing the design, the self-weight can be reduced, the weight of the end wall of the railway truck body can be reduced, and the bearing capacity of the vehicle can be improved. After the hollow aluminum profile is extruded, the wall panel 1 is integrated. The closed box structure further improves the structural stability, and its strength and rigidity are high, and the bearing capacity is strong. Moreover, the surface of the hollow aluminum profile is relatively smooth, so that the inner wall of the end wall is relatively smooth, and the body of the vehicle body is smooth. There are no bumps or corners inside, which can reduce the probability of cargo accumulation and freezing in the car, and the unloading rate of the cargo is high.

Please refer to FIG. 5-7. FIG. 5 is a schematic front structural view of the end wall shown in FIG. 4. FIG. 6 is a side structural view of the end wall shown in FIG. 4. FIG. 7 is a cross-sectional structural view of the BB direction in FIG. .

Each of the dividing wall panels 1 may be sequentially connected to form the end wall panel 2, and the end wall panel 2 may be inclined from top to bottom, as shown in FIGS. 5 and 6, so as to form an inclined angle, and the inclined angle may be greater than The angle of repose of the bulk cargo on the end wall, so that the cargo is automatically unloaded under the weight of its own weight.

When the end wall panel 2 is disposed obliquely, a support panel 3 for supporting the end wall panel 2 may be provided, as shown in FIGS. 5 and 6; the support panel 3 may be supported on the outer side of the end panel 2, and may be combined with the end wall The plate 2 is at an angle, and the support plate 3 can also be disposed obliquely with an oblique direction opposite to the inclined direction of the end wall panel 2 to support the end wall panel 2.

It is also possible to provide a support column on the support plate 3 to increase the strength of the support plate 3 so as to form a simple plate-column structure with the support plate 3; the support column may be disposed along the extending direction of the support plate 3, or may be in any direction It is disposed on the support plate 3.

Generally, in the railway trucks such as the hopper car, the length of the end wall is large, and in order to avoid bending deformation of the entire end wall structure, an appropriate support can be added in the length direction of the end wall panel 2, the support plate 3 and the support column. The simple slab-column structure can play this supporting role, which greatly reduces the probability of bending deformation of the end wall.

The joint of the two-part wall panel 1 may be held in the same plane as the inner side panel 11 and the outer side panel 12, or may be recessed inwardly to form the recess 18, as described in detail below with respect to the recess 18. As shown in FIG. 7, the joint of the two-part wall panel 1 may have a recess 18, and the cross-section of the recess 18 may be a trapezoid-like structure, such as an isosceles trapezoidal structure, to facilitate the connection between the partition panels 1. The connecting member used for the connection is prevented from protruding from the surface of the inner side panel 11 or the outer side panel 12, affecting the use of the end wall panel 2 or the connection of the end wall panel 2 to other structures.

When the junction of the two-part wall panel 1 has a recess 18, a spacer 4 may be provided to fill the spacer 4 in the recess 18 so as to be substantially flush with the outer panel 12 to form a connection for supporting the support panel 3. The connecting surface, as shown in FIG. 5, can connect the upper end surface of the support plate 3 to the outer side surface of the end wall panel 2 to improve the reliability of the connection.

It should be noted that, in the structure of the end wall panel 2 shown in FIG. 7, the spacer 4 is directly filled in the recess 18 so as to form a joint surface with the outer panel 12; the structure of the recess 18 is clearly shown. In FIG. 7, only one of the grooves 18 is vacant, that is, one of the grooves 18 does not fill the pad 4. It should be understood by those skilled in the art that the expression is only required here, and it is not necessary to fill the groove in the groove 18. 4.

In order to improve the connection reliability of the support plate 3 and the end wall panel 2, the spacer 4 should generally match the structure of the recess 18 to prevent the spacer 4 from swaying in the recess 18 and affect the positioning reliability of the support panel 3.

Further, an upper end beam 5 may be disposed above the end wall panel 2 to block the cargo and improve the structural strength and stability above the vehicle body, as shown in FIGS. 5 and 6.

In detail, a connecting plate 6 for connecting the end wall panel 2 and the upper end beam 5 may also be provided. Generally, the upper end beam 5 and the end wall panel 2 may be at a predetermined angle, and the predetermined angle may be adjusted according to the load bearing and connection requirements, etc.; since the end wall panel 2 is inclined from the top to the bottom, and the upper end beam 5 Connected above the end wall panel 2, the angle between the upper end beam 5 and the end wall panel 2 is generally obtuse and on the inside, as shown in FIG. The end wall panel 2 can be inclined outward, and the upper end beam 5 can extend in the up and down direction, that is, the end surface of the upper end beam 5 can be vertically disposed, and the inner side angle formed between the upper end beam 5 and the end wall panel 2 is an obtuse angle, which is convenient. The two are connected, and the connecting plate 6 can be disposed; at this time, the connecting plate 6 can be provided as a bending member, and can include two sub-boards, and the two sub-boards can be bent at the predetermined angle so as to be combined with the upper end beam 5 and The end wall panels 2 are matched, that is, the two sub-boards can be respectively connected with the upper end beam 5 and the end wall panel 2, thereby realizing the reliable connection of the upper end beam 5 and the end wall panel 2.

Further, as shown in FIG. 7, in the partition wall panel 1 of the present invention, the left side of the partition wall panel 1 at the left end may be bent inward to form a left bent portion 16 for connecting the side wall of the railway wagon; Similarly, the right side of the partition wall panel 1 at the right end may also be bent inward to form a right bent portion 17, which is also used for connection with the side wall of the railway wagon so that the entire end wall panel 2 is connected to the side. The ends of the wall together form the railway wagon shown in Figure 3.

The left bent portion 16 and the right bent portion 17 may be perpendicular to the inner side plate 11 or opposite to the inner side plate 11 by a certain angle; may be a plate-like or columnar structure, or may be other parts such as a card portion. Connected structure.

It is conceivable that the left bent portion 16 and the right bent portion 17 have various structural forms, and are not limited to the above-described structural form as long as the partition wall panel 1 can be connected to the side wall.

On the basis of the above, the partition wall panels 1 of the present invention can be fixed by means of welding or riveting.

Please refer to FIG. 8-11. FIG. 8 is a partially enlarged schematic view showing the connecting portion 15 of the dividing wall panel 1 according to the present invention in a first arrangement manner; FIG. 9 is a connecting portion of the dividing wall panel 1 provided by the present invention. 15 is a partially enlarged schematic view of the second arrangement mode; FIG. 10 is a partially enlarged schematic view showing the connection portion 15 of the partition wall panel 1 provided in the third arrangement mode of the present invention; FIG. The connecting portion 15 of the wall panel 1 is divided into a partial enlarged view in the fourth arrangement.

Specifically, a rivet hole may be provided on the connecting portion 15, and then riveting is performed by a rivet. Alternatively, the connecting portion 15 may be welded to realize the connection between the dividing wall panels 1, as shown in FIG.

After the partition wall panels 1 are inclined inwardly at the ends of the respective outer side panels 12, the outer side panels 12 and the inner side panels 11 can be connected, so that the two side panels are connected to form one side panel, which reduces the connection portion 15 in the inner and outer directions. The thickness, which corresponds to the inward recess of the entire wall panel at the position of the connecting portion 15, forms a groove-like structure at the joint portion 15 between the two adjacent end wall panels 2. When the riveting structure is adopted, the groove 18 provides a space for the rivet head or the rivet collar, which can prevent the rivet protrusion from affecting the use of the end wall, and avoids the load bearing due to the installation of the rivet; when the welded structure is used There is no need to separately weld the inner side panel 11 and the outer side panel 12, which simplifies the welding process.

When the partition wall panel 1 is welded, the inner panel 11 and the outer panel 12 may be separately welded, that is, the partition panels 1 are sequentially welded by the respective inner panels 11 and sequentially welded by the respective outer panels 12.

In detail, the weld between the inner side plates 11 may form a funnel-shaped weld bead, that is, the end portion of the inner side plate 11 may be provided with a tapered surface so that the adjacent inner side plates 11 form a funnel shape when they are joined. The cavity 7 facilitates the filling of the solder so that the solder fills within the cavity 7, ultimately forming a funnel-shaped weld. Similarly, the weld of the outer side plate 12 can also form a funnel-shaped weld seam. The specific structure can also adopt the structure of the inner side plate 11, as shown in FIG.

When a funnel-shaped weld is used, the solder can be sufficiently filled to improve the connection reliability; the solder can also flow in the oblique direction of the funnel under the action of gravity, etc., and the randomness of the solder flow can be reduced to effectively fill the weld. And it will not form welding bumps on the surface of the end wall, and will not affect the loading and unloading of the cargo.

Furthermore, an adjustable solder joint form can also be used. As shown in FIG. 11, the end of the inner side plate 11 and/or the outer side plate 12 can be provided with a receiving hole 8 for filling the solder; or each wall can be divided. The plates 1 are sequentially inserted or packaged, and then the receiving holes 8 are provided at the plugs or sets so that the solder is filled in the receiving holes 8; it is also possible to directly select the appropriate connection at each of the dividing wall plates 1 The position of the weld.

When the above structure is adopted, the installation position of the accommodating hole 8 can be adjusted, or the insertion depth or the package depth between the wall panels 1 can be adjusted to adjust the welding position and achieve a reliable connection.

It should be understood by those skilled in the art that other fixing manners such as pinning can be used between the dividing wall panels 1. For the specific connecting manner, please refer to the prior art.
