Abstract
The utility model discloses a lorry-mounted crane base, which comprises a base and landing legs positioned at two ends of the base. A horizontal oil cylinder for controlling the transverse distance between the two landing legs is arranged in the base, and a perpendicular oil cylinder for adjusting the height of each landing leg is arranged at the lower end of the landing leg. The landing legs are controlled to move by means of oil supply of the horizontal oil cylinder to realize distance change of the base, so that stability of the base is enhanced. The perpendicular length of the landing legs is changed by means of oil supply of the perpendicular oil cylinders to adapt to multi-field operation (such as unsmooth roads), so that stability and safety of the lorry-mounted crane base are realized.
Description
Technical field
The utility model has related to a kind of lorry-mounted crane, relates in particular to the lorry-mounted crane base.
Background technology
Lorry-mounted crane is meant and is installed on the car chassis, within the specific limits many actions elevator machinery of vertical-lift and horizontal carrying heavy goods.According to lever principle, under the certain situation of pressure, fulcrum is far away more, and needed power is just more little.The base width of lorry-mounted crane and stability and safety when highly having determined its operation; Because base is fixed; Receive environmental factor restriction (uneven like road) during operation, stability is difficult to control during its operation, secondly; The stability of base should change with the weight of goods, is difficult to guarantee safety.
The utility model content
The technical matters that the utility model will solve is in order to overcome technological deficiency recited above, a kind of lorry-mounted crane base to be provided.
In order to solve technical matters recited above, the utility model is taked following technical scheme:
The utility model provides a kind of lorry-mounted crane base, includes base, is positioned at the supporting leg of base two side ends, is provided with the cross cylinder that is used to control transverse distance between two supporting legs in the described base.
Described supporting leg lower end is provided with the vertical oil cylinder that is used to regulate height of landing leg.
The utility model is controlled moving of supporting leg through the fuel feeding of cross cylinder, realizes the change of base distance, thereby strengthens the stability of base; Realize that through the fuel feeding of vertical oil cylinder vertical direction props up the change of leg length, can adapt to multi-field operation (like the road unfairness), and realize its stability and safety.
The utlity model has following characteristics:
1) during lift cargo, vehicle does not topple;
2) according to institute's hoisting thing weight, change base supporting leg distance, guarantee safety.
3) the adjustable supporting leg of above-below direction can be realized the multi-field operation of hoisting crane
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, 1. base, 2. supporting leg, 3. vertical oil cylinder, 4. cross cylinder.
The specific embodiment
See also Fig. 1; As shown in the figure, the lorry-mounted crane base includes base 1, is positioned at the supporting leg 2 of base 1 two side ends; Be provided with the cross cylinder 4 that is used to control transverse distance between two supporting legs in the base 1, supporting leg 2 lower ends are provided with the vertical oil cylinder 3 that is used to regulate height of landing leg.
The utility model is controlled moving of supporting leg through the fuel feeding of cross cylinder, realizes the change of base distance, thereby strengthens the stability of base; Realize that through the fuel feeding of vertical oil cylinder vertical direction props up the change of leg length, can adapt to multi-field operation (like the road unfairness), and realize its stability and safety.
Claims (2)
1. a lorry-mounted crane base includes base, is positioned at the supporting leg of base two side ends, it is characterized in that: be provided with the cross cylinder that is used to control transverse distance between two supporting legs in the described base.
2. lorry-mounted crane base as claimed in claim 1 is characterized in that: described supporting leg lower end is provided with the vertical oil cylinder that is used to regulate height of landing leg.
