Problems solved by technology

[0004] The object of the present invention is to provide a telescopic arm control structure of a truck-mounted crane to solve the problem that the structure of the telescopic boom of a truck-mounted crane currently on the market is not only cumbersome and complicated, but also difficult to manufacture and high in production cost. In addition, the expansion and contraction is mostly carried out by cylinder or electric method, which consumes more energy and has poor practicability, which can no longer meet the needs of the existing market.

Abstract

The invention discloses a crane telescopic arm control structure of a truck mounted crane, and relates to the technical field of truck mounted cranes. The crane telescopic arm control structure comprises a base arm, wherein one side of the base arm is fixedly equipped with a first fixed frame, and the other side of the base arm is embedded with a first telescopic arm; the inner part of the base arm is fixedly equipped with a telescopic gas cylinder; the top of the base arm is equipped with a first rope row fixing frame; and one side of the first telescopic arm is embedded with a second telescopic arm. The crane telescopic arm control structure is simple, scientific and reasonable in structure; in a practical using process, the first telescopic arm is driven to extend out towards the rightside in a sliding mode while the telescopic gas cylinder operates, and a movable pulley extends out to drive a first steel wire rope to move towards the right side, so that the second telescopic arm is driven to extend out towards the right side, and therefore, opening of the second telescopic arm is realized; and while the telescopic gas cylinder drives the first telescopic arm to retract, a second steel wire rope drives the second telescopic arm to move towards the left side through a second rope row fixing base, so that retraction of the second telescopic arm is realized, and therefore, thepurpose of integrally retracting the telescopic arm is achieved.

Description

technical field [0001] The invention relates to the field of truck-mounted crane technology, in particular to a control structure for a telescopic arm of a truck-mounted crane. Background technique [0002] The truck-mounted lifting transport vehicle, referred to as the truck-mounted crane, is a kind of equipment that realizes the lifting, turning, and lifting of goods through hydraulic lifting and telescopic systems. It is usually assembled on a truck, and generally consists of a truck chassis, Composed of cargo compartment, power take-off and crane. The truck-mounted crane integrates hoisting and transportation, and is mostly used in stations, warehouses, docks, construction sites, field rescue and other places. The telescopic boom is one of the main structures of the crane. [0003] However, the structure of the telescopic arm of the truck-mounted crane currently on the market is not only cumbersome and complicated, but also difficult to manufacture, and the production ...
