Abstract

The invention discloses a boarding ladder with a safety locking mechanism. The boarding ladder comprises a ladder frame, a ladder body, a pull rope device and the safety locking mechanism. The ladderframe is connected to a hanging cabin; the ladder body is connected to the inside of the ladder frame in a sliding mode; the pull rope device is connected with the ladder body and used for drawing theladder body to slide up and down in the ladder frame; and the safety locking mechanism prevents the ladder body from continuously falling in the ladder frame after a steel cable in the pull rope device is broken or a power device in the pull rope device is powered off and loses power. The boarding ladder can adapt to the severe environment of a mine working condition, the structure is reliable, and safety and stability are improved; and the mechanical locking mechanism can avoid potential safety hazards caused by steel cable breakage or sudden power loss in the ladder body descending process.

Description

technical field [0001] The invention belongs to the field of construction machinery, and in particular relates to a boarding ladder and a large excavator with a safety locking mechanism. Background technique [0002] The boarding ladder involved in the present invention is a lifting type. The ladder with this structure has occasional situations such as sudden power failure and steel cable breakage in the process of retracting and unwinding the ladder. If it slides down, people under the ladder may be injured or objects under the ladder may be damaged. This device has certain potential safety hazards. Therefore, it is necessary to have a safety locking mechanism. [0003] However, the existing electronic or hydraulic safety mechanisms have higher requirements on the quality of the parts, and the purely mechanical safety mechanism of the present invention can greatly reduce the maintenance times of the parts, and is an economical and reliable mechanism. Contents of the inve...
