Abstract

The invention provides a displacement device disposed between the rotary table and control room of an engineering machine. The displacement device comprises a four-bar linkage and a first transmission mechanism. The four-bar linkage consists of a frame body, an upper side link body, a connecting rod body and a lower side link body that are hinged in order. The first transmission mechanism is disposed between the frame body and the rotary table, and used for driving the four-bar linkage to rotate relative to the rotary table horizontally. A first oil cylinder is positioned between the frame body and one of the upper side link body and the lower side link body. The connecting rod body is in connection with the control room. The displacement device of the invention can be convenient for staff to get in and out of the control room and can broaden the horizon of staff. In addition, the invention also provides a crane with the above displacement device.

Description

technical field [0001] The invention relates to the technical field of construction machinery displacement, in particular, a displacement device is designed. In addition, the present invention also relates to the field of hoisting equipment, in particular to a crane. Background technique [0002] With the rapid development of the economy, large-scale projects continue to increase. The scale of construction projects in wind power, thermal power, nuclear power and other energy industries continues to expand, hoisting projects are developing in the direction of large-scale and large-scale, and the application range of cranes is also becoming wider and wider. [0003] The control room of the crane is the command center to realize the work of the crane and the link of man-machine connection. [0004] The control room is installed on the turntable of the crane, and the position of the control room needs to be changed according to the different requirements of the lifting state a...
