Description

Efficient waterproof structure of side beam at bottom of carriage

Technical Field

The utility model belongs to the technical field of the carriage is made, concretely relates to high-efficient waterproof construction of carriage bottom curb girder.

Background

The carriage is generally of a hexahedral structure and mainly formed by assembling six panels and eight corner wrapping pieces, and when the panels are assembled, the joints between the two panels are connected through the corner wrapping pieces. Because the material of cornerite spare is thicker, therefore the bottom of the carriage has been enclosed into the closed loop that is less than the vehicle bottom board by the cornerite spare all around, the height of carriage has been raised, but when the bottom of the carriage ponding condition was serious, still can take place the phenomenon of overflow in the carriage, and the waterproof construction of current bottom of the carriage adopts to scribble sealed glue on the contact surface of cornerite and vehicle bottom board, whole waterproof construction has waterproof measure single thin, waterproof performance is poor, sealed glue is easy by the weak point of the ponding corruption of vehicle bottom, in case sealed glue is corroded the back, the bottom of the carriage has just lost waterproof function.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving prior art's not enough, provide a high-efficient waterproof construction of carriage bottom curb girder, including first baffle, second baffle and third baffle, first baffle be located between carriage curb plate and the carriage bottom plate, first baffle is Z type spare, the second baffle be located between first baffle and the carriage curb plate, the upper surface of first baffle links to each other with the floor, the floor on be equipped with the third baffle.

Preferably, a cavity is arranged below the carriage side plate, a reinforcing piece is arranged in the cavity, and the reinforcing piece is connected with the second partition plate.

In order to ensure that a sufficient drainage space is left between the first partition plate and the compartment side plate, the second partition plate is preferably an L-shaped member.

Preferably, the compartment side plate, the first partition plate and the compartment bottom plate are connected through rivets.

Preferably, the third partition is fixed to the floor by bolts.

When the accumulated water at the bottom of the carriage is too much, in order to ensure that the accumulated water does not enter the carriage, preferably, the side edge of the third partition plate is provided with a water retaining flange, and the water retaining flange is connected with the side plate of the carriage through a rivet.

Preferably, the joint of the third partition board and the floor is sealed and waterproof.

Has the advantages that: the utility model discloses a high-efficient waterproof construction of carriage bottom curb girder compares in prior art, the utility model discloses a set up waterproof construction between carriage curb plate and carriage bottom plate, prevented effectively that ponding from getting into the carriage from the junction of carriage curb plate and carriage bottom plate in, improved the waterproof performance in carriage.

FIG. 2 is an enlarged partial schematic view of area A of FIG. 1;

in the figure: 1. the compartment side plate 11, the cavity 12, the reinforcement 2, the compartment bottom plate 3, the waterproof structure 31, the first partition plate 32, the second partition plate 33, the third partition plate 34, the water retaining flange 4 and the floor

Detailed Description

In order to deepen the understanding of the present invention, the present invention is described in detail with reference to the following embodiments and the attached drawings, and the embodiments are only used for explaining the present invention, and do not constitute the limitation to the protection scope of the present invention.

As shown in fig. 1 and 2, a high-efficiency waterproof structure of a side sill at the bottom of a carriage, the waterproof structure 3 includes a first partition plate 31, a second partition plate 32 and a third partition plate 33, the first partition plate 31 is located between a side plate 1 and a floor plate 2, the side plate 1, the first partition plate 31 and the floor plate 2 are connected through rivets, the first partition plate 31 is a Z-shaped member, the second partition plate 32 is an L-shaped member, the second partition plate 32 is located between the first partition plate 31 and the side plate 1, a cavity 11 is arranged below the side plate 1, a reinforcement member 12 is arranged in the cavity 11, the reinforcement member 12 is connected with the second partition plate 32, the upper surface of the first partition plate 31 is connected with a floor 4, the floor 4 is provided with the third partition plate 33, the third partition plate 33 is fixed on the floor 4 through bolts, and the joint of the third partition plate 33 and the floor 4 is subjected to sealing and waterproof treatment, the side edge of the third partition plate 33 is provided with a water retaining flange 34, and the water retaining flange 34 is connected with the carriage side plate 1 through a rivet.

The working condition is as follows: as shown in fig. 1 and 2, when there is accumulated water at the bottom of the carriage, the accumulated water will enter the waterproof structure 3 along the gap between the first partition plate 31 and the carriage side plate 1, when there is excessive accumulated water at the bottom of the carriage, in order to ensure that the accumulated water does not enter the carriage, a water-retaining flange 34 is arranged on the side edge of the third partition plate 33, and a water accumulation gap is formed between the water-retaining flange 34 and the carriage side plate 1; when the accumulated water at the bottom of the carriage is reduced, the accumulated water in the carriage side plate 1 and the carriage bottom plate 2 flows out along the water inlet path.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
