Embodiment Construction
[0033] Hereinafter, the present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be noted that, on the premise of no conflict, the embodiments or technical features described below can be arbitrarily combined to form new embodiments. .
[0034] It should be noted that when a component is referred to as being "fixed to" another component, it can be directly on the other component or there may also be a centered component. When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a co-existence of an intervening component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a co-existing centered component. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for illustrative purposes only.
[0035] Unless otherwise de...

The cantilever type beam lifting station is used for hoisting and erecting the beam plate on a bridge and comprises a supporting assembly and a crown block assembly, the supporting assembly comprises a first side steel pipe stand column and a second side steel pipe stand column, and the crown block assembly comprises a self-propelled crown block beam and a winch moving along the self-propelled crown block beam. The upper parts of the first side steel pipe upright post and the second side steel pipe upright post are fixedly connected with the self-propelled crown block beam. The supporting assembly and the crown block assembly are matched for hoisting, I-beam bridge edge hoisting is achieved, hoisting is more efficient, faster and more convenient, high stand column construction outside a bridge edge line is not needed, the risk of high-altitude operation is reduced, installation can be achieved only through a prefabricated bridge deck slab and a beam conveying channel below, the restriction influence of a site outside the bridge edge line is reduced, and the construction efficiency is improved. The construction difficulty is reduced, multi-point putting of equipment is facilitated, the beam lifting construction efficiency is improved, the beam lifting station is simple in structure, the mounting and dismounting difficulty is greatly reduced, and the turnover efficiency is high.
Description
technical field [0001] The invention relates to the field of bridge construction, in particular to a cantilever beam-lifting station for beam-slab erection and a method for hoisting and hoisting a bridge. Background technique [0002] At present, the upper structure of the viaduct adopts the prestressed concrete I-beam, the bridge deck is continuous, and the bridge erection machine is mainly used for the overall lifting construction. [0003] However, the traditional beam lifting station designed as a high and low leg gantry crane has the following disadvantages: [0004] 1. The steel pipe column is relatively high, there are certain safety hazards in high-altitude operation, and the structural safety performance requirements of the bracket are relatively high, making it inconvenient to hoist; [0005] 2. The installation site requirements are relatively high. The beam-lifting station needs a flat and open site outside the bridge to pour the enlarged foundation, and the bea...
