Abstract

The utility model relates to a built-in telescopic counterweight mechanism of a lorry-mounted crane, and belongs to the built-in telescopic counterweight mechanism of the lorry-mounted crane. The telescopic counterweight mechanism comprises a telescopic counterweight (1), a telescopic oil cylinder (2), a telescopic arm (3) and a fixed arm (4); wherein, the fixed arm is connected with a body frame; the telescopic arm (3) is sleeved in the fixed arm; the telescopic oil cylinder (2) is connected in the fixed arm (4) and the telescopic arm (3); one end of the telescopic oil cylinder (2) is connected with the fixed arm (4); the other end thereof is connected with the telescopic arm (3); and the outer end of the telescopic arm (3) is connected with the telescopic counterweight (1). The whole counterweight mechanism is fixed in the middle of the rotating table of the crane; the telescopic counterweight is arranged at the back side of the rotating table; and the telescopic oil cylinder drives the telescopic arm to extend. The utility model has the following advantages: the telescopic counterweight mechanism effectively improves the stability of the whole machine, in particular the stability of the large-tonnage lorry-mounted crane, provides more choices for the matching chassis of the crane, reduces the processing difficulty, facilitates the operation, saves the space and provides the development trend of the counterweight plan for the large-tonnage lorry-mounted crane.

Description

The built-in extendable weight of lorry-mounted crane mechanism
Technical field
The utility model relates to a kind of counter weight device of work post machinery, the built-in extendable weight of a kind of especially lorry-mounted crane mechanism.
Background technology
At present, domestic lorry-mounted crane develops into 10 tons, 12 tons, 16 tons and this year 25 tons of maximum by 3.2 tons, 6.3 tons, but development along with the large-tonnage lorry-mounted crane, clump weight on lorry-mounted crane relies on and strengthens the large-tonnage lifting function that clump weight is realized continuous development also in continuous increase.
The utility model content
The purpose of this utility model is to provide a kind of: the built-in extendable weight of the lorry-mounted crane mechanism that need not strengthen clump weight.
The purpose of this utility model is achieved in that this extendable weight machinery includes extendable weight (1), telescopic oil cylinder (2), telescopic boom (3) and fixed arm (4), fixed arm is connected with on this, in fixed arm, be socketed with telescopic boom (3), in fixed arm (4) and telescopic boom (3), be connected with telescopic oil cylinder (2), telescopic oil cylinder (2) one ends are connected with fixed arm (4), the other end is connected with telescopic boom (3), is connected with extendable weight (1) in the outer end of telescopic boom (3).
Beneficial effect: owing to adopted such scheme, whole balance weight mechanism is fixed in the middle of the rotating platform of crane, and extendable weight is positioned at the turntable rear side, driving telescopic boom by telescopic oil cylinder stretches, when hoisting crane is worked, can determine to stretch out backward the distance of counterweight according to different operating modes, guarantee the stability of complete machine with this, when hoisting crane was not worked, extendable weight may be withdrawn into the turntable rear side again, is close to turntable, need not strengthen clump weight, reach the purpose of this utility model.Advantage: complete machine stability has effectively improved in this extendable weight mechanism, and especially large-tonnage makes hoisting crane that more selection arranged when the coupling chassis with the stability of car lifting, difficulty of processing is low, easy to operate, save the space, be the developing direction of large-tonnage lorry-mounted crane counterweight scheme.
