Cranes with anti-derailment devices

Abstract

The invention relates to a crane with an anti-derailment device, which includes an electric hoist, an active trolley and a driven trolley fixedly connected to the electric hoist, and is characterized in that: the outer side of the active trolley is provided with a guard hook assembly connected with the electric hoist. The guard hook assembly is composed of a guard hook body, a guard hook connecting frame and fasteners, and adjustment holes are arranged on the guard hook body and the guard hook connecting frame in a direction perpendicular to each other. The advantage is: when the crane has an abnormal situation, such as the wheel assembly deviating from the track and the crane is seriously deflected, the guard hook body can be tightly stuck to the track, thereby preventing the crane from derailing. This not only improves the safety of the crane in use, but also prevents the occurrence of vicious events such as derailment and falling of the crane under special and unexpected circumstances. Moreover, it can also ensure the personal safety of the operator, avoid damage to the transported items and bring unnecessary economic losses to the user.

Description

technical field [0001] The invention belongs to the technical field of crane equipment, in particular to a crane with an anti-derailment device. Background technique [0002] At present, in order to make the crane, especially the suspension crane, run safely on the track, the way of installing horizontal wheels is usually used to ensure that the crane runs smoothly according to the designed track. Because the horizontal wheel axis in the known technology is perpendicular to the wheel axis, it can only prevent the wheel from gnawing on the rail, and does not have the function of preventing derailment. Limitations of the existing structure: Under special working conditions and accidents, it is easy to cause the occurrence of vicious events such as derailment and falling of the crane. This will not only endanger the personal safety of the operator, but also cause damage to the transported items, bringing unnecessary economic losses to the user. Contents of the invention [...
