A tower hoisting device that effectively reduces the corrosion of connecting bolts of the boom

Abstract

The invention discloses a tower type hoisting device for effectively relieving cargo boom connecting bolt rust. The tower type hoisting device comprises a foundation fixing device, a supporting arm, aprotection device and protection shells. The supporting am is vertically arranged at the top end of the foundation fixing device. The top end of the part, at the outer portion of the supporting arm,of the foundation fixing device is provided with the protection device. An operation chamber is arranged at the top end of the front face of the supporting arm. Cargo booms are transversely fixed to the top end of the part, behind the operation chamber, of the supporting arm. The cargo booms are fixedly connected through connecting rods. The top ends of the parts, at the connecting positions of the cargo booms and the connecting rods, of the cargo booms are provided with the protection shells. Anti-corrosion paint is arranged at one ends in the protection shells. By means of the tower type hoisting device, rust of cargo boom connecting bolts can be effectively relieved, and the service life of the connecting bolts is prolonged; meanwhile, through the arrangement of the foundation fixing device, stability and safety of the device are improved; and through the arrangement of the protection device, the device is effectively protected against collisions.

Description

technical field [0001] The invention relates to the technical field of tower lifting devices, in particular to a tower lifting device that can effectively reduce the corrosion of connecting bolts of a boom. Background technique [0002] The tower crane is the crane with the largest working space in the construction industry. It has a large lifting height and a large working range. It belongs to the high-altitude function. It is currently a horizontal or vertical hoisting and transporting mechanical equipment commonly used on construction sites. Therefore, the tower crane can continue to innovate and develop. , basically meet the needs of people, but there are still some problems. Because tower cranes generally work outdoors, tower cranes often face various bad weather. In the long run, the connecting bolts of the boom will gradually rust. At the same time, because it belongs to high-altitude operations, it needs to be fixed to make it have a stable structure. At the same tim...
