A movable driver's cab of a slewing crane

Abstract

The invention discloses a movable cab of a slewing crane. The movable cab comprises a cab body and a crane rotary table, wherein the cab body is positioned above the crane rotary table. The movable cab is characterized in that a cab moving mechanism capable of driving the cab body to forwards and wholly move away from the edge of the rotary table by a length of distance from the initial position is arranged between the cab body and the crane rotary table; the cab moving mechanism comprises a connecting rod group and a power device; the connecting rod group comprises a plurality of connecting rods, an upper connecting rod support is arranged on a seat plate of the cab body, a lower connecting rod support is arranged on the crane rotary table, the upper end of each connecting rod is hinged onto the upper connecting rod support, and the lower end of each connecting rod is hinged onto the lower connecting rod support. After the movable cab of the slewing crane provided by the invention is used, a fixed cab can be changed into the movable cab only by additively arranging a set of cab moving mechanism between the original cab and the crane rotary table, so that the cab is movable when goods at the bottom of a cabin is unloaded, and therefore, the view range of the driver can be preferably enlarged on the premise that the safety is guaranteed.

Description

technical field [0001] The present invention relates to a driver's cab of a slewing crane, in particular to a driver's cab in which the position of a slewing crane, especially a port portal crane, can be adjusted by moving back and forth, so that the driver of the slewing crane can have more Good field of view. Background technique [0002] The driver's cab of the existing slewing crane is arranged on the slewing platform, and the position of the driver's cab is fixed. In order to ensure that when the crane is at the minimum range, the hoisted cargo still has a sufficient safety distance from the driver's cab when it is deflected inward. When there is cargo at the bottom of the cabin, the area where the driver can directly see the bottom of the cabin is very small. For other invisible unloading areas, special personnel need to be added to command through gestures and walkie-talkies. The loading and unloading efficiency is low, and safety accidents occur from time to time. ...

When there is cargo at the bottom of the cabin, the area where the driver can directly see the bottom of the cabin is very small, and other invisible unloading areas need to be commanded by special personnel through gestures and walkie-talkies. The loading and unloading efficiency is low, and safety accidents often occur
