Truss crane equipment and application thereof

Abstract

The invention discloses truss crane equipment which comprises two parallel rails, wherein a walking trolley is arranged above each of the rails; the two walking trolleys are a fixed end trolley I anda movable end trolley II separately; a wheel is arranged below each of the walking trolleys; one of the wheels is a driving wheel; the walking trolleys are driven by a motor and a reducing mechanism to walk; a transverse beam is erected between the two walking trolleys; the movable end trolley II and the transverse beam can relatively slide; scales are marked on the transverse beam; reading marksof the scales are arranged on the movable end trolley II; and a hand chain hoist is mounted on the transverse beam. The truss crane equipment can be applied to installation of a culvert cover plate; atruss crane can be rapidly assembled and detached along with culvert construction; after the truss crane equipment is used, the truss crane equipment is detached and transported to a next construction site for application, and the width of the transverse beam can be adjusted to enable the truss crane equipment to be used in an occasion with any width.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to truss lifting equipment and its application. Background technique [0002] Truss cranes are also known as line cranes and portal bridge cranes. They are very common in civil engineering and engineering. Both ends are located on tall cement columns or metal supports. The space under the bridge frame lifts materials without being hindered by ground equipment. It is a kind of hoisting machinery with the widest range and the largest number. [0003] Culverts refer to drainage channels (water passages) built under the roadbed and built below the road surface in order to allow the road to pass through the canal smoothly in the construction of highway projects. The culvert structure allows water to flow under the road. Or across large and small roads as overpasses for people, livestock and vehicles, or as water channels for farmland irrigation. Culverts are mainly composed of cav...

AI Technical Summary

Problems solved by technology

During the construction of the cover plate, the prefabricated cover plate is usually transported to the site by truck first, and the truck crane arrives at the site at the same time. The truck crane lifts the cover plates on the truck one by one, puts them on the wing wall, and aligns them for installation. In the first process, due to the long length of the culvert, there is also a high requirement for the length of the car boom; In the hoisting operation of a long distance, the operator needs to have high operating skills to put down the cover plate in the aligned position, which is time-consuming and labor-intensive
