Tower crane with water spray and dust prevention functions

Abstract

The invention discloses a tower crane with water spray and dust prevention functions. The tower crane comprises a crane body. The crane body comprises a fixed supporting frame, a rotary control room, a cantilever lazy arm and a winch trolley mechanism. The bottom end of the rotary control room is fixed to the fixed supporting frame. One end of the cantilever lazy arm is connected with the rotary control room. The winch trolley mechanism is arranged on the cantilever lazy arm. The lower end of the winch trolley mechanism is connected with a hook assembly. A water storage tank is arranged at the upper end of the cantilever lazy arm. The bottom end face of the cantilever lazy arm is provided with a plurality of sprinkler heads. The outer frame wall of the fixed supporting frame is also provided with a plurality of sprinkler heads connected with the water storage tank. In this manner, water can be sprayed outwards in a scattered manner through the sprinkler heads on the fixed supporting frame, the sprinkler heads on the cantilever lazy arm can be used for carrying out 360-degree rotating water spray, and therefore the water spray range is widened, and raising dust on construction sites is eliminated.

Description

Technical field [0001] The invention relates to the field of cranes, and in particular to a water-sprinkling and dust-proof tower crane. Background technique [0002] Tower crane, referred to as tower crane, also known as tower crane, originated in Western Europe. A rotating crane with a boom mounted on the upper part of a towering tower. It has a large working space and is mainly used for vertical and horizontal transportation of materials and installation of building components in house construction. It consists of three parts: metal structure, working mechanism and electrical system. The metal structure includes the tower body, boom and base. The working mechanism has four parts: lifting, luffing, turning and walking. The electrical system includes motors, controllers, distribution cabinets, connecting lines, signals and lighting devices, etc. However, the general tower crane is simply used as a lifting tool and lacks other functions. Dust is often raised on the cons...

AI Technical Summary

Problems solved by technology

However, the general tower crane is simply used as a lifting tool and lacks other functions. Dust is often raised on the construction site, which not only affects the air quality, but also brings certain troubles to the operators on the construction site. In some cases, it is easy to Affects the hoisting sight of the crane, and the traditional tower crane does not have the function of watering, which cannot eliminate the dust brought up on the construction site
