Embodiment Construction

[0021] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0022] Such as figure 2 , image 3 and Figure 4 As shown, a preferred crane of the present invention includes a turntable 3, a jib system 6, a cab 7, a passive mechanism 8, and a luffing mechanism 4. The jib system 6 is installed on the turntable 3, and the luffing mechanism 4 is used to drive the arm The frame system 6 is used for luffing, and the passive mechanism 8 is used to level the cab 7. The passive mechanism 8 is respectively hinged with the turntable 3 and the jib system 6. The cab 7 is installed on the passive mechanism 8.

[0023] Such as Figure 4 As shown, the passive mechanism 8 includes a first link 80 , a second link 81 , a third link 82 , and a fourth link 83 . The first ...

Abstract

The invention discloses a driven mechanism capable of expanding the visual field of a gantry crane cab. The driven mechanism is hinged with a rotary table and a boom system respectively; the cab is installed on the driven mechanism; the driven mechanism comprises a first connecting rod, a second connecting rod, a third connecting rod and a fourth connecting rod, which are sequentially hinged with one another end to end. The invention also discloses a crane. According to the driven mechanism capable of expanding the visual field of the gantry crane cab and the crane, the cab is installed on the driven mechanism, and moves along with the boom system so that the visual filed of the cab can be effectively expanded, the mounting and demounting efficiency can be effectively improved, and safety accidents caused by narrow visual field can be avoided; when the boom system performs luffing action under the action of a luffing mechanism, the driven mechanism is driven to act by virtue of the luffing power of the boom system, so that the cab is always at a horizontal moving state, the operation comfort is ensured, and the visual field of the cab can be adjusted.

Description

technical field [0001] The invention relates to the field of hoisting machinery, in particular to a passive mechanism and a crane that can improve the field of view of a driver's cab of a portal crane. Background technique [0002] Portal crane is an important and representative rotating type rail-running crane. It is named for its gantry structure that allows transport vehicles to pass smoothly. Modern portal cranes are widely used in the mechanized loading and unloading of goods in ports and wharves, in the construction and installation of ships in shipyards, and in the dam construction of large hydropower stations. It is of great significance that it is an indispensable and important equipment to realize the mechanization of the production process. [0003] Such as figure 1 As shown, the portal crane consists of a portal 2, a turntable 3, a cart mechanism 1, a slewing mechanism, a luffing mechanism 4, a lifting mechanism, a self-balancing system 5, a cab 7, and a jib sy...
