Abstract

一种罩式货车车厢的门扇，具有自动启闭的功能，结构由两排小门组成，小门的一边分别连接固定在门框的侧面。另一边缘在门框的中间处相交接触，以封闭装车的门洞。小门带有弧度且向下，小门用锯条钢带做成，以确保有足够的持久弹性。装车时，小门在煤炭的重力作用下向外自动打开，停装后小门在形变弹力的作用下又恢复原状。

Description

罩式货车车厢的门扇
技术领域
一种罩式货车车厢的门扇，属于铁路运输领域。
背景技术
罩式货车车厢，专利号：200810165886.X，用于装车的门洞是由两块门扇封闭的，这种门扇不具有自动启闭的功能，不利于该技术的应用推广。
发明内容
本申请的目的：是要设计一种和该车相配套的“罩式货车车厢的门扇”，它具有自动启闭的功能，以此降低推广应用的难度。
首先将车厢上原有的两个门扇去掉，在门框的长边侧面安装两排小门，小门和门框相连成一体。两排小门的另一边缘在门框的中间处相交接触，以封闭装车的门洞。小门的形状为带有弧度的长方形的弹性板体，两排小门的弧度向下，小门用锯条钢带做成，以确保有足够的持久弹性。小门的弹性强度调整方法为，选用不同厚度的锯条钢带进行加工制作。
装车时，煤炭从天仓的漏斗下泄，煤炭的自身重力将小门向下打开，小门发生弹性形变，煤炭冲过小门后落入车厢，停装后小门在形变弹力的作用下又恢复原状，完成对罩式货车车厢的门洞封闭。门上残留的少许煤炭，由于处在两个小门最低洼的缝隙处，也不易被风吹走。
附图说明

1、门框，2、小门。
具体实施方式
如图1、2所示，首先将车厢上原有的两个门扇去掉，在门框1的长边侧面安装两排小门2，小门2和门框1相连成一体。两排小门2的另一边缘在门框1的中间处相交接触，以封闭装车的门洞。小门2的形状为带有弧度的长方形的弹性板体，两排小门2的弧度向下，小门2用锯条钢带做成，以确保有足够的持久弹性。小门2的弹性强度调整方法为，选用不同厚度的锯条钢带进行加工制作。
装车时，煤炭从天仓的漏斗下泄，煤炭的自身重力将小门2向外打开，小门2发生弹性形变，煤炭冲过小门后落入车厢，停装后小门2在形变弹力的作用下又恢复原状，完成对罩式货车车厢的门洞封闭。
