Technical Field

The utility model relates to a track machinery brake technical field specifically is a track machinery crane is with preventing rising hot brake equipment.

Background

The crane refers to a multi-action crane for vertically lifting and horizontally carrying heavy objects within a certain range. Also known as crown blocks, navigation cranes and cranes; the crane mainly comprises a hoisting mechanism, a running mechanism, a luffing mechanism, a slewing mechanism, a metal structure and the like.

The track is cooperated with the crane to work, the track deck in the existing equipment is mostly made of rigid materials, and due to the particularity of the work, the materials with higher rigidity can not cause the track to deform under pressure, so that the work of the track is influenced.

The problem that the too big material rigidity brought is just, it is more difficult when sliding assembly installs on the track, and among the sliding assembly of traditional draw bridge each direction sliding assembly all can not be adjusted, in addition, sliding assembly is very fast at the speed that the track slided, the pulley is if adopt traditional friction braking's mode when the braking, can lead to its surface to produce high temperature, the temperature can be along with the conduction of rigid metal material, cause certain influence to the material of hoist and mount, consequently a track machinery crane takes place with preventing hot brake equipment.

Disclosure of Invention

Can adjust, need not the purpose of friction braking for realizing above-mentioned installation, the utility model provides a following technical scheme: the utility model provides a track machinery crane is with preventing hot brake equipment that rises, includes the casing, the inside swing joint of casing has the gyro wheel, and the fixed surface of gyro wheel is connected with the connecting rod, the inside fixedly connected with spring of connecting rod, and the surface swing joint of spring has the extrusion pipe, and the lower extreme fixedly connected with aerofoil of spring, the upper end fixedly connected with slide of spring, one side fixedly connected with piston rod of spring are kept away from to the slide, and the wave tube has been cup jointed on the surface of piston rod, and the inside fixedly connected with of gyro wheel cuts apart the board, cuts apart the fixed surface of board and is connected.
