Problems solved by technology

The hydraulic components that make up the hydraulic system——hydraulic pumps, pressure control valves, flow control valves, directional control valves, hydraulic cylinders, etc. need to choose a high pressure level and a large flow rate, which will lead to an increase in the price of the hydraulic system , the production cost of hydraulic crane increases
Hydraulic cranes and hydraulic excavators have single operating functions and are purchased separately, increasing construction costs

Embodiment Construction

[0015] like figure 1 As shown, the multi-functional crane excavator is based on the crawler excavator chassis, and is equipped with main arm, auxiliary arm, balance arm, support seat, luffing hydraulic cylinder, balance hydraulic cylinder, main hydraulic winch, auxiliary hydraulic winch, movable balance Counterweight composition.

[0016] like figure 1 As shown, the main arm is composed of a main pulley, a main arm body, a V-shaped arm, a main sliding arm, a main sliding arm hydraulic cylinder, a main arm hydraulic cylinder, a luffing hydraulic cylinder, and a rib plate.

[0017] The main arm body is made of rectangular section steel, and the middle part is processed with a hinge hole connected with the piston rod of the luffing hydraulic cylinder. The intersection of the "V"-shaped arm made of rectangular section steel is welded to the end of the main arm body, and this end of the main arm body is processed with a hinge hole that is hinged to the tail end of the main slidin...

Abstract

The invention relates to a multifunctional crane excavator which has both the hoisting function and the excavating function. By using a chassis of a crawler excavator as an excavator body, the multifunctional crane excavator is provided with a main arm, an auxiliary arm, a balance arm, a supporting seat, a derricking hydraulic cylinder, a main hydraulic winch, an auxiliary hydraulic winch and a balance weight. A gravitational moment which is generated when the multifunctional crane excavator carries out lifting and excavating operations is balanced by a gravitational moment of the balance arm at the other end of the supporting seat; the gravitational moment which is generated during lifting and excavation does not act on the body of the multifunctional crane excavator fully, the roll-over action on the multifunctional crane excavator is very small, therefore, the safety under the condition of the same lifting and excavating capability is improved. Accordingly, the invention is quite suitable for application in special lifting sites and special excavating operations.

Description

technical field [0001] The invention relates to a multi-functional hoisting machine which not only has the function of hoisting but also has the function of excavating. Therefore, the machine can be used not only as a hydraulic crane, but also as a hydraulic excavator. It can be used in municipal construction, real estate development, and transportation construction projects, especially in water conservancy, electric power, petrochemical, mining and metallurgical construction projects, and has substantial use value. Background technique [0002] When the hydraulic crane lifts heavy objects in the form of a cantilever crane, the lifting heavy objects will act a tipping moment on the hydraulic crane, making the hydraulic crane in a tipping state. The lifting weight is balanced by the lifting balance moment of the hydraulic crane, so that the hydraulic crane remains stable. The lifting moment of the hydraulic crane is composed of the product of the lifting arm and the weight ...
