Attached type bridge crane and construction method thereof

Abstract

The invention relates to an attached type bridge crane, belonging to the technical field of bridge construction equipment. The attached type bridge crane comprises a left support beam and a right support beam, which are distributed on the side surfaces of a left bridge pier stud and a right bridge pier stud respectively, wherein two horizontal jib crane main beams which are the same in height and are arranged in parallel are arranged between the top ends of the left support beam and the right support beam, the left ends of the two jib crane main beams are overhung on the left support beam, track beams are arranged on two jib crane main beams respectively, a bridge running mechanism is arranged on two track beams in a sliding connecting manner by a first roller, a bridge frame longitudinal beam is arranged on the bridge running mechanism, a crane carriage is arranged on the bridge frame longitudinal beam in a sliding connecting manner by a second roller, a hook is arranged at the bottom end of the crane carriage, and a winch connected with the hook is arranged on the crane carriage. The attached type bridge crane has the characteristics of requirement on set-up of an elevated trackway on the ground and small interference to the underside of the equipment.

Description

technical field [0001] The invention belongs to the technical field of bridge construction equipment, and in particular relates to an attached bridge crane and a construction method. Background technique [0002] In bridge construction, bridge cranes are also widely used because of their large lifting capacity, wide lifting range, high lifting height, and low interference to the space below the equipment. However, when the bridge cannot directly pre-lay the track on the main structure due to its own structural characteristics, and there are factors such as high-altitude construction, water construction, and complex terrain conditions that make it impossible to install the elevated track on the ground, the existing form of bridge crane installation exists. A problem with greater difficulty and a large impact on performance. Contents of the invention [0003] The object of the present invention is to provide a kind of attached bridge crane and construction method aiming at ...
