Abstract

The invention discloses a braking device for a building tower crane rotation shaft. The braking device for the building tower crane rotation shaft comprises a main mounting plate. The braking device for the building tower crane rotation shaft uses liquid power in the same drive source, can perform braking action of relative positions of the inner round end face and the outer side face of a rotation column, achieves omni-directional frictional contact, enlarges the contact area, reduces pressure on surfaces of components in braking, and guarantees braking strength on the premise of guaranteeinguse life of the components, and additionally the braking device for the building tower crane rotation shaft is provided with a spiral spring compression colliding type maximum liquid pressure difference control mechanism, and prevents a force-induced deformation phenomenon caused by overlarge liquid pressure difference to the hollow rotation column from occurring, and the braking device for the building tower crane rotation shaft is provided with a ring array spiral spring colliding type maximum rotation strength control mechanism, and prevents a steel wire fracture phenomenon caused by overlarge barking strength from occurring in the braking, and additionally the braking device for the building tower crane rotation shaft is provided with a rotation shaft spiral structure type mounting fixing mechanism, and can perform mounting fixing on different dimeters of shaft bodies.

Description

technical field

[0001] The invention relates to the technical field of construction equipment, in particular to a braking device for a rotating shaft of a construction tower crane. Background technique

[0002] At present, tower cranes are used in construction sites, and the braking effect of the existing braking devices in tower cranes is relatively low. Since tower cranes are hoisted at relatively high positions, once a falling accident occurs, it will cause greater danger. sex. Contents of the invention

[0003] The object of the present invention is to provide a braking device for the rotating shaft of a construction tower crane to solve the problems raised in the above-mentioned background technology.

[0004] In order to achieve the above object, the present invention provides the following technical solutions: a brake device for the rotating shaft of a building tower crane, comprising a main mounting plate, two opposite main support rods are installed on the upper ...
