Double-acting ladder stand structure and overhead working truck
The invention belongs to the technical field of crawling ladders, and discloses a double-acting crawling ladder structure and an overhead working truck. The double-acting crawling ladder structure comprises a mounting frame and a rotating body. The mounting frame is arranged on the overhead working truck, and a ladder climbing port is formed in one side; the rotating body has a ladder climbing state and a protection state relative to the mounting frame, and the rotating body comprises a main frame body, a pedal ladder and a protective fence. The pedal ladder and the protective fence are both arranged on the main frame body, and the main frame body is rotationally arranged on the mounting frame. When the main frame body rotates to a ladder climbing state, the pedal surface of the pedal ladder faces upwards, and the main frame body drives the protective fence to rotate to the lower side of the mounting frame so as to avoid the ladder climbing port; and when the main frame body rotates to a protection state, the main frame body drives the protective fence to rotate to one side of the mounting frame so as to block the ladder climbing opening. According to the double-acting ladder stand structure, the rotating body has two states relative to the mounting frame, so that a worker can climb a vehicle through the ladder climbing opening in the ladder climbing state, and the protective fence can block the ladder climbing opening in the protection state.
本发明属于爬梯技术领域，公开了一种双作用爬梯结构及高空作业车。双作用爬梯结构包括安装架和转动体。安装架设置于高空作业车上，且一侧设置有登梯口；转动体相对安装架具有爬梯状态和防护状态，转动体包括主架体、脚踏梯以及防护栏。脚踏梯和防护栏均设置于主架体上，主架体转动设置于安装架上。当主架体转动至爬梯状态时，脚踏梯的脚踏面朝上，主架体带动防护栏转动至安装架的下侧以避让登梯口；当主架体转动至防护状态时，主架体带动防护栏转动至安装架的一侧以封挡登梯口。该双作用爬梯结构，转动体相对安装架具有两种状态，以使得在爬梯状态时工作人员能够通过登梯口登车，在防护状态时，防护栏能够封挡登梯口。
