Embodiment 1

[0034] Please also refer to Figure 1-4 , the present embodiment provides a crane bridge, including a main girder 100 and two end girders 200 arranged at both ends of the main girder 100 and perpendicular to the main girder 100, specifically:

[0035] The main beam 100 overlaps the upper parts of the two end beams 200 , and the main beam 100 and the end beams 200 are connected by a hinge device 300 .

[0036] The bridge frame of the crane includes the main girder 100 and the end girder 200, which constitute the metal structure skeleton of the crane to bear and transmit various working loads, natural loads and self-weight loads borne by the crane. The end girder 200 is arranged at both ends of the main girder 100 Therefore, there are two end girders 200, and the end girder 200 is vertically arranged relative to the main girder 100, which constitutes the basic form of the bridge frame. On the two end beams 200, the force of the main beam 100 is transmitted through the end beams...

Embodiment 2

[0046] This embodiment provides a crane, including the bridge frame of the crane in Embodiment 1. The crane also includes a trolley mounted on the main girder 100, a trolley operating mechanism located at the bottom of the two ends of the end beam 200, an electrical device for providing lifting and operating power for the trolley and the trolley operating mechanism, and equipment The railing on the main girder 100 and the driver's cab connected to the main girder 100, because the bridge frame of the crane adopts the hinged connection mode of the main girder 100 and the end girder 200, avoiding the use of traditional bolts used between the main girder 100 and the end girder 200 The connection method makes the installation of the main girder 100 and the end girder 200 convenient and fast, and the preset hinge device 300 on the main girder 100 and the end girder 200 compared with the preset bolt holes of the traditional connection method reduces the manufacturing process and speed...

Abstract

The invention provides a bridge frame of a crane and the crane, which relate to the technical field of hoisting machinery. The bridge frame of the crane includes a main girder and two end girders arranged at both ends of the main girder and perpendicular to the main girder. , which solves the technical problems in the prior art that the installation accuracy of the main girder and the end girder of the crane is difficult to guarantee and the installation is inconvenient, and it is easier to ensure the connection between the main girder and the end girder by hinged connection The installation accuracy greatly improves the installation efficiency, reduces the workload of manufacturing and installation, plays a certain role in protecting the metal structure of the crane, and at the same time improves the safety performance of the crane.

Description

technical field [0001] The invention relates to the technical field of hoisting machinery, in particular to a bridge frame of a crane and the crane. Background technique [0002] Hoisting machinery refers to electromechanical equipment used for vertical lifting or vertical lifting and horizontal moving of heavy objects. As an important material handling equipment, cranes have gone through thousands of years of development. The solid wood structure cranes driven by human and animal power in the past It has evolved into a steel structure crane driven by machinery and hydraulic pressure, and enjoys many poetic titles. With the rapid development of my country's national economy, the continuous expansion of production scale, and the unprecedented prosperity of metallurgy, shipbuilding, power construction, petrochemical and other industries , Cranes have become an indispensable and important lifting equipment in modern industrial production. [0003] The bridge frame of the crane i...
