Problems solved by technology

However, in the process of lifting the limit bolt, the trajectory of the pedal is a circular arc, so the limit bolt will inevitably be subjected to two directions of force, which will interfere with the guide groove of the limit bolt, resulting in either the limit bolt cannot be lifted. up, or cannot return after lifting up, resulting in functional failure and potential safety hazards
[0004] The traditional solution is to use grease or lubricating oil for lubrication, which will improve after use, but still cannot completely avoid the phenomenon of sticking

Abstract

The invention discloses an upper platform extending limiting device of an aerial work platform. The upper platform extending limiting device comprises an upper platform body and an extending part. The extending part is installed in the upper platform body and can slide in the length direction of the upper platform body. A limiting assembly is arranged between the upper platform body and the extending part. The limiting assembly comprises a locking mechanism and a limiting block. The locking mechanism is installed on the extending part. The limiting block is installed on the upper platform body. The locking mechanism slides to the limiting block of the upper platform body along the extending part to achieve limiting fixing. The upper platform extending limiting device is simple in structure and convenient to control, and the construction safety of personnel is improved.

Description

technical field [0001] The invention relates to a limiting device for an aerial work platform, in particular to an upper platform extension limiting device for an aerial work platform. Background technique [0002] The aerial work platform is a product that serves mobile aerial work such as aerial work, equipment installation, and maintenance in various industries. The top of the aerial work platform is the upper platform used to carry the workers. In order to expand the working range, the mechanism of the upper platform is usually an extendable mechanism. limited mechanism. [0003] At present, most of the extension limit of the platform on the domestic aerial work platform adopts the structure of the pedal and the limit pin. rise. The limit bolt is installed in the mounting seat, and returns through the compression spring in the mounting seat, and the mounting seat is installed on the base. When it is necessary to move the platform, step on the pedal, and lift the limi...
