Abstract

The invention provides a swinging ladder with a locking mechanism and a locking method. When an SQ6 type double-layer car transporting vehicle needs to load and unload two layers of cars, a two-layerplatform is temporarily constructed by using a manual pushcart; and the mode of manually constructing the two-layer platform has the defects that time and labor are wasted, the working efficiency is greatly reduced and economic benefits are directly affected. The swinging ladder with the locking mechanism comprises a swinging ladder body (1); one end of the swinging ladder body is hinged with a folding seat plate (2); the locking mechanism (5) is arranged at the other end of the swinging ladder body; the locking mechanism comprises a locking hook (14); the locking hook is hinged with a lockinghook adjusting seat (15); a locking hook adjusting seat pin shaft (11) and a locking nut (10) are correspondingly welded on the side wall of the swinging ladder body; and the locking hook adjusting seat pin shaft penetrates through a strip-shaped hole (18) in the locking hook adjusting seat to be connected with the locking hook adjusting seat in a sliding manner. The swinging ladder with the locking mechanism and the locking method are used for the swinging ladder with the locking mechanism and the locking method.

Description

Technical field: [0001] The invention relates to a swing ladder with a locking mechanism and a locking method. Background technique: [0002] With the rapid development of my country's national economy, the demand for family cars is also increasing. The medium and long-distance transportation of cars is mainly completed by railways. Among them, the SQ6 double-deck car transport vehicle is the main vehicle for railway transport cars. . Domestic large and medium-sized cities with large car turnover usually have fixed end platforms on the first and second floors, while stations in smaller cities with small car turnover generally only have a first-floor end platform. When it is necessary to load and unload cars on the second floor Only human carts can be used to temporarily build the second-floor platform. This method of manually building the second-floor platform is time-consuming and laborious, which greatly reduces work efficiency and directly affects economic benefits. I...
