Control cabin modified gear and engineering machine

Abstract

The invention discloses a control cabin modified gear of an engineering machine. The control cabin modified gear comprises a control cabin body (1), a rotary rack (4) which is in revolving connection with a rotary table of the engineering machine, a telescopic component (3), a first rod (2) and a limiting mechanism, wherein the telescopic component (3) is used for supporting the control cabin body (1) and driving the control cabin body (1) to move up and down; the two ends of the first rod (2) are hinged between the rotary rack (4) and the control cabin body (1); the limiting mechanism is arranged at a preset position and is used for limiting the rotation of the first rod (2); and under the action of the telescopic component (3), the control cabin body (1) rotates around the hinge point of the control cabin body (1) and the first rod (2) in a vertical plane. The control cabin modified gear disclosed by the invention is simple in structure and is favorable for lightening the weight of a complete machine; and two operations, namely pitching and fluctuating, are completed by only one telescopic component, thus the arrangement of a hydraulic system and an electrical system of the engineering machine can be favorably simplified, and simultaneously, the use cost of the engineering machine can be lowered. The invention also provides the engineering machine comprising the control cabin modified gear.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a displacement mechanism for a control room of an engineering machinery. In addition, the present invention also relates to a construction machine comprising the above-mentioned control room displacement mechanism. Background technique [0002] The all-terrain crane is a typical construction machinery. Because of its fast transfer speed and wide application in the lifting environment, it is widely used in the hoisting industry. With the continuous development of wind power, nuclear power and chemical industries, Hoisting operations have higher and higher requirements for the use of all-terrain cranes, and the required tonnage is also increasing. [0003] All-terrain cranes are generally equipped with a control room. In order to meet the requirements of vehicle transportation and operator comfort during hoisting operations, most control rooms have the function of mu...

AI Technical Summary

Problems solved by technology

[0005] In order to realize the displacement function of the above-mentioned control room, the commonly used technical means in the prior art are: using different independent oil cylinders to realize the pitch displacement and lifting displacement; the pitch displacement and the lifting displacement are controlled by different oil cylinders It satisfies the demand for the displacement of the control room of the crane, but the number of oil cylinders is relatively large, resulting in a more complicated structure of the control room displacement mechanism, more difficult assembly and maintenance, and the weight of the whole machine is relatively large, which is not conducive to the design of the whole machine

[0006] In addition, the more the number of oil cylinders, the more complicated the hydraulic system and control system of the corresponding construction machinery, which increases the difficulty of design and the relatively high cost of use
