Embodiment Construction

[0045] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the embodiments described below are only a part of the embodiments of the present application, not all of them. Based on the embodiments described in this application, all other embodiments obtained by those skilled in the art without creative efforts are within the protection scope of this application.

[0046] The inventors of the present application found in the research that the boarding mechanism is necessary for the emergency repair of lifting equipment (such as double-girder bridge type, gantry type, etc.), but the existing lifting equipment itself does not have a perfect boarding mechanism. machine design. The boarding method of the general bridge crane still depends o...

Abstract

The invention belongs to the field of cranes, and particularly provides a crane first-aid repair device and a crane.The crane first-aid repair device comprises a driving module and an aerial ladder; the driving module is arranged on a counterweight side or a main beam of the crane and is used for ascending or descending the scaling ladder; and one end of the scaling ladder is fixed on the driving module and is used for personnel to climb. When the crane breaks down, the scaling ladder can be lowered through the driving module, so that a maintainer climbs up the crane through the scaling ladder to maintain the crane, a boarding channel is provided for a first-aid repair worker, boarding first-aid repair of the maintainer is facilitated, the time that the hoisting equipment cannot be used due to defects can be shortened, and the maintenance efficiency is improved. And therefore, huge production benefit loss caused by the fact that the hoisting equipment cannot be used is avoided.

Description

technical field [0001] The application belongs to the field of cranes, and in particular relates to a crane emergency repair device and a crane. Background technique [0002] As a special equipment commonly used in industry, cranes sometimes fail in daily production and use, requiring crane special operation maintenance personnel to climb on the main girder of the crane for emergency repairs. If the crane fails to move, the crane does not stop at the parking space when it stops, and there are no lifelines or other forms of walking platforms and guardrails installed beside the cart rails at both ends of the crane, in this case the driver cannot get off the car through the boarding gate In addition, the maintenance personnel could not immediately board the crane through the boarding gate for quick repair. In the end, the only way to get on the crane was by setting up scaffolding. [0003] In order to meet the needs of lifting heavy objects, the crane body is mostly on the up...
