Dynamic windproof device of rail-mounted crane

Abstract

The invention discloses a dynamic windproof device of a rail-mounted crane, which comprises a monitoring component, a trigger component, a power transfer component and a buffer component. The monitoring component is connected with the trigger component, the trigger component is arranged on a crane trolley, the buffer component is arranged on a lower cross beam of the crane and a cart anchorage device, and the power transfer component is connected with the trigger component and the buffer component. Through the components, under abrupt gust, the crane is blown to a definite speed and the gust continuously accelerates; under the condition that the prior windproof device such as a metal shoe rail clamping device and the like cannot act, the dynamic windproof device realizes safe and steady braking of the crane; self wheel pressure of wheels of the crane trolley provides positive pressure, the rolling is changed into sliding, and a friction material is added, so the friction coefficient ofcontact faces is improved, the energy is saved, and the windproof grade is improved; and the buffer component of the invention makes the braking mild under the action of wind of different grades, ensures that the mechanical property of each component can be fully exerted, improves the windproof reliability, and ensures stability.

Description

technical field [0001] The invention belongs to the technical field of wind protection of cranes, is mainly used for dynamic wind protection of rail cranes such as gantry type, portal type and quay bridge type, and is a dynamic wind protection device for rail-type cranes. Background technique [0002] At home and abroad, major safety accidents of rail-mounted cranes are often caused by wind disasters. The crane was subjected to unforeseen sudden gusts of wind under working conditions, and achieved great speed in a very short period of time without the operator's awareness. The braking torque of the crane's original traveling brake is too small to withstand the wind, which makes the crane continue to accelerate, and eventually hits the adjacent crane or end block, causing the crane to overturn, resulting in serious loss of life and property. In view of the major accidents of cranes caused by wind disasters, there are currently a series of auxiliary windproof safety measures,...

AI Technical Summary

Problems solved by technology

[0003] The problem to be solved by the present invention is that the existing windproof device for rail-mounted cranes cannot realize effective windproofing when the crane is running, and a device that can brake the crane smoothly and safely when there is a sudden gust of wind during the walking process of the crane is needed
