Problems solved by technology

If a synchronous telescopic mechanism with a single-stage telescopic cylinder plus multiple sets of rope row components is used, under heavy load conditions, the thrust of the single-stage telescopic cylinder is limited, and it is impossible to reliably realize the synchronous telescopic expansion of the four-section boom; Oil cylinders are used for synchronous control. Due to the limited space of the boom of the truck-mounted crane and high safety requirements, it is inconvenient to install multiple single-stage telescopic cylinders in the boom with limited space, and its own weight is too heavy, which is not convenient for the use of the truck-mounted crane.

Embodiment Construction

[0042] The present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. In the description of this application, the "head", "tail", "horizontal", "vertical", "upper", "lower" orientations or positional relationships are based on the normal use state of the synchronous telescopic mechanism of the truck-mounted crane, that is The outstretched end of the synchronous telescopic mechanism of the truck-mounted crane is the head end, and the end opposite to the head end is the tail end. It should be understood that these orientation terms are only for the convenience of describing the application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a reference to the application. limits.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a synchronous telescopic mechanism of a truck-mounted crane. Background technique [0002] In the prior art, the synchronous telescopic mechanism of the four-section boom truck-mounted crane has two telescopic methods, one is to use a single-stage telescopic cylinder plus multiple sets of rope row components for synchronous telescopic control, and the other is to use multiple single-stage telescopic cylinders synchronous control. If a synchronous telescopic mechanism with a single-stage telescopic cylinder and multiple sets of rope row components is used, under heavy load conditions, the thrust of the single-stage telescopic cylinder is limited, and it is impossible to reliably realize the simultaneous telescopic expansion of the four-section boom; Oil cylinders are used for synchronous control. Due to the limited space of the boom of the truck-mounted crane and high safety ...
