Abstract
A waterproof structure at the lower part of a rear door of a cargo compartment of a plug board van comprises a rear door board, a sealing strip, a floor rear cross beam and a rear door lower cross beam; the rear door plate is fixedly arranged at the reserved position of the freight car body, the sealing strip is fixedly connected with the lower part of the rear door plate, the floor rear cross beam is fixedly arranged at the reserved position of the floor of the freight car body, and the rear door lower cross beam is fixedly connected with the floor rear cross beam; the utility model discloses reduce back door bottom end rail, make back door bottom end rail upper plane and floor back end rail upper plane form the difference in height, after freight train waterproof stripe became invalid, rivers can be along the gap discharge between floor back end rail and the back door bottom end rail, can not flow into goods railway carriage or compartment inside, reach the waterproof effect of structure, whole structure is drawn materials simply, low cost, water-proof effects is good.
Description
Technical Field
The utility model relates to a waterproof construction in back door lower part of plugboard van goods railway carriage or compartment back door belongs to the waterproof technical field in carriage.
Background
The van is also called a van and is mainly used for sealing and transporting various articles, most of the carriages of the existing van are formed by welding common steel or riveting aluminum plates, and then the water leakage is prevented by gluing the joints. However, because the carriage planking area is great, takes place to warp easily in the use and leads to the junction to split and glue, can't guarantee the waterproof performance in carriage, after goods railway carriage or compartment door bottom joint strip ageing failure, because back door bottom end rail upper flat surface flushes with the floor plane, the rainwater also can flow back into inside the goods railway carriage or compartment.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a waterproof construction in back door lower part of plugboard van goods railway carriage or compartment door to after solving the ageing inefficacy of goods railway carriage or compartment door bottom joint strip, because plane and floor plane flush on the back door bottom end rail, the rainwater can flow back into the inside, the poor problem of water-proof effects of goods railway carriage or compartment.
The purpose of the utility model is realized like this: a waterproof structure at the lower part of a rear door of a cargo compartment of a plug board van comprises a rear door board, a sealing strip, a floor rear cross beam and a rear door lower cross beam; the rear door plate is fixedly arranged at the reserved position of the freight car cargo compartment, the sealing strip is arranged at the lower part of the rear door plate, the floor rear cross beam is horizontally and fixedly arranged at the reserved position of the freight car cargo compartment floor, and the rear door lower cross beam is horizontally and fixedly connected with the floor rear cross beam, and the rear door lower cross beam is characterized in that: the floor bottom end rail upper surface is higher than the back door bottom end rail upper surface, and back door bottom end rail and floor back end rail fixed connection mode are spot welding, leave the gap between the face of weld, and rivers can directly discharge from the welding gap, and the structure is waterproof, and water-proof effects is good, and simple structure is practical.
Specifically, the floor rear cross beam comprises an upper surface plate and a lower surface plate, one side of the upper surface plate is connected with one side of the lower surface plate through a side plate, the free end of the upper surface plate extends downwards to form a connecting panel used for being connected with the floor rear cross beam, and the lower surface plate extends downwards to form a guide plate.
More specifically, the upper surface plate is provided with water leakage holes.
More specifically, the rear floor cross beam and the lower rear door cross beam are made of high-strength steel.
More specifically, the sealing strip is H-shaped, and the upper part of the H-shaped part receives the lower part of the door panel and is fixedly connected with the door panel.
More specifically, the upper plane of the rear floor beam is higher than the upper plane of the lower rear door beam, and the upper plane of the rear floor beam is higher than the lower plane of the sealing strip; forming a height difference and preventing water flow from directly entering the cargo compartment.
The utility model discloses reduce back door bottom end rail, make back door bottom end rail upper plane and floor back end rail upper plane form the difference in height, after freight train waterproof stripe became invalid, rivers can be along the gap discharge between floor back end rail and the back door bottom end rail, can not flow into goods railway carriage or compartment inside, reach the waterproof effect of structure, whole structure is drawn materials simply, low cost, water-proof effects is good.
