A sewage tank for high-speed trains

Abstract

The utility model discloses a kind of dirt boxes for high-speed train, the dirt box for high-speed train includes box and protection frame, protection frame is attached to box surface and is located outside installation area, protection frame will the area of box surface located outside installation area is divided into several rectangular reinforcing areas;Reinforcing area is provided with the protruding part that is protruded to box, protruding part is obtained by deformation corresponding to reinforcing area, the protruding height of protruding part is ≤8mm.The utility model provides a kind of dirt box for high-speed train has the effect of reducing box self weight while ensuring the strength of box.

Claims

1. A waste bin for high-speed trains, comprising a bin body (11) and a protective frame (21), characterized in that: The protective frame (21) fits against the surface of the box (11) and is located outside the installation area (12). The protective frame (21) divides the area of ​​the box (11) outside the installation area (14) into several rectangular reinforcing areas (12). The reinforcing area (12) is provided with a protrusion (31) that protrudes outward from the box. The protrusion is formed by deformation of the corresponding reinforcing area (12). The protrusion height of the protrusion (31) is ≤8mm.

2. A waste bin for high-speed trains according to claim 1, characterized in that: For any of the protrusions (31), the protrusion (31) includes a peripheral surface (33) and an end surface (32), the end surface (32) is parallel to the corresponding reinforcing region (12), and the peripheral surface (33) gradually narrows along the protrusion direction of the protrusion (31).

3. A waste bin for high-speed trains according to claim 2, characterized in that: The peripheral surface (33) protrudes outward along a cross section perpendicular to the reinforcing region (12); And / or, the circumferential surface (33) extends smoothly along a cross section perpendicular to the reinforcing region (12); And / or, the area ratio of the end face (32) to the reinforcing region (12) is (0.3-0.6):

1.

4. A waste bin for high-speed trains according to claim 2, characterized in that: The end face (32) is a regular polygon with rounded corners, and the regular polygon is a centrally symmetrical figure.

5. A waste bin for high-speed trains according to claim 4, characterized in that: The end face (32) is a rounded rectangle or a circle.

6. A waste bin for high-speed trains according to claim 4, characterized in that: The center of the end face (32) and the center of the reinforcing region (12) are located on the same straight line perpendicular to the reinforcing region (12).

7. A waste bin for high-speed trains according to claim 1, characterized in that: The box body (11) is formed by splicing multiple box panels, and two adjacent box panels are connected by an arc-shaped surface (13).

8. A waste bin for high-speed trains according to claim 7, characterized in that: The protective frame (21) has a portion that fits the arcuate surface (13).

9. A waste bin for high-speed trains according to claim 7, characterized in that: One of the multiple box panels located at the bottom of the box body (11) is the bottom plate. The bottom plate is provided with several installation areas (14) and several reinforcing areas (12). The installation areas (14) on the bottom plate are all used as heating areas.

10. A waste bin for high-speed trains according to claim 1, characterized in that: The protective frame (21) is also provided with reinforcing beams (25).
