Abstract

本发明公开了一种起重机安全车挡结构，解决现有车挡结构容易撞车的技术问题。其结构是，将现有固定车轮轴承箱的弯板的垂直端向下延长，延长长度达到能与小车轨道碰头相碰的位置，且在延长段的背面焊接有支撑板。本发明用于起重机小车上。

Description

起重机安全车挡结构
技术领域
本发明涉及起重机，尤其涉及起重机小车。
背景技术
现有的起重机都必须在小车轨道的两端设置“碰头”，在小车上设置“车挡”，以使小车在轨道上限位运行。目前的车挡结构，都是设计成一个独立的部件，将其焊接在小车的车轮轴承箱弯板上。这种焊接结构在长期碰撞中，尤其是焊接不牢时易发生变形断裂，失去挡车作用，造成撞车事故。
发明内容
本发明的目的是解决现有车挡结构的不足，提供一种起重机安全车挡结构。
这种起重机安全车挡的结构是：它包括现有固定车轮轴承箱的弯板，其特征是，弯板的垂直端向下延长，延长长度达到能与小车轨道碰头相碰的位置，且在延长段的背面焊接有支撑板。
本发明的优点是：它与固定车轮轴承箱的弯板是一个完整的整体，不用单独加工焊接，避免了因焊接瑕玼造成的断裂变形现象，达到行车安全的目的。
附图说明
图1是本发明的结构图。
图中：1-弯板，2-延长段，3-碰头，4-支撑板。
具体实施方式
从图1可以看出，它的结构是：将现有的固定车轮轴承箱的弯板1有一段伸到与碰头2相碰位置的延长段3，延长段3的背面焊接有支撑板4。
