Abstract

The utility model discloses a lifting device for rigid hinges and large components, belongs to the field of bridge construction devices and discloses a lifting device for the rigid hinges and the large components of different lifting tools of bridge floor cranes. The lifting device comprises bridge floor crane winches, wherein each bridge floor crane winch comprises a steering fixed pulley and connecting fixed pulleys, a top fixed pulley group and a moving pulley group which are connected through a steel wire rope, and ends of the two steel wire ropes of the bridge floor crane winches are connected in series through the steering fixed pulleys on the bridge floor crane winches. By the aid of the lifting device, the problems that postures in the air are difficult to control and the stress exerted on a single lifting point exceeds the limit easily when the bridge floor cranes are used for lifting the rigid hinges, steel box girders or large structures are solved, and lifting risks and the operation difficulty are reduced.

Description

The boom hoisting of a kind of rigidity hinge and large-scale component
Technical field
The utility model belongs to the bridge construction apparatus field.
Background technology
Adopted the bridge floor loop wheel machine to carry out in steel case beam or other large structure lifting constructions in the past, loop wheel machine left and right sides suspender is separate, namely have independently separately hoist, weighing system, in steel case beam hoisting process, must observe the aerial statue of steel case beam and the situation of change of weighing system constantly, as note abnormalities, need operating personnel manually to carry out the adjusting of left and right sides suspender, otherwise cause loop wheel machine monolateral stressed excessive easily, whole unstability.
Because fibrous root manually carries out the adjusting of suspender according to the aerial statue of steel case beam in steel case beam hoisting process, but be difficult to find suitable observation point in construction, and steel case beam lifting altitude is big, the left and right sides suspender that often needs to carry out is repeatedly regulated, difficulty of construction is big, the risk height.Especially lift jointly under the working condition of steel case beam 4 of many bridge floor loop wheel machines, the situation that probably exists diagonal two suspension centres can lift by crane whole weights will cause single suspension centre hoisting system ability to exceed design load, and potential safety hazard is quite big.
The utility model content
The purpose of this utility model is: propose a kind of boom hoisting of realizing the different suspender rigidity hinges of bridge floor loop wheel machine and large-scale component, solve bridge floor loop wheel machine stressed problem that easily transfinites of aerial attitude control big, the single suspension centre of difficulty in carrying out steel case beam or large structure hoisting process, reduce lifting risk and task difficulty.
The utility model purpose realizes by following technical proposals:
The boom hoisting of a kind of rigidity hinge and large-scale component, comprise the bridge floor loop wheel machine hoist engine that is provided with the connection fixed pulley, top fixed pulley group and the running block that are connected by wire rope, described bridge floor loop wheel machine hoist engine also is provided with and turns to fixed pulley, and the wire rope end of two bridge floor loop wheel machine hoist engines is connected by turning to fixed pulley on it.
As optimal way, described two bridge floor loop wheel machine hoist engines are the left and right hoist engine of same bridge floor loop wheel machine.
As optimal way, described two bridge floor loop wheel machine hoist engines are the hoist engine of different bridge floor loop wheel machines.
As optimal way, described connection fixed pulley race direction is consistent with rope traction direction on it.
As optimal way, the described fixed pulley race direction that turns to is consistent with rope traction direction on it.
As optimal way, the described fixed pulley that turns to is located at described bridge floor loop wheel machine underframe rear side main couple place.
As optimal way, described connection fixed pulley and turn to fixed pulley to be provided with the wire rope groove separation preventing device.
As further preferred embodiment, described wire rope groove separation preventing device is the spacing strength plate of pulley base.
The course of work is: will remove fixing former two bridge floor loop wheel machine hoist engine wire rope ends, the fixed pulley that turns to that passes separately connects, and after joint is connected, slowly starts hoist engine respectively wire rope is strained, and can form the connection of this device.The left and right sides hoist engine (or hoist engine of different bridge floor loop wheel machines) of existing bridge floor loop wheel machine is two independently hoisting systems, and this device with its series connection after can with two independently system be linked as integral body, the stability that hoists stressed, works for large structure hoisting process loop wheel machine has a self-regulating function thus, guarantee two loop wheel machines lifting stress equalization, works lifting process balance.Its self-regulating principle is exactly: the system after the series connection is subjected to force self-balanced adjusting by turning to fixed pulley to finish, and then because the self-balancing on stressed determines the aerial statue of works to be in a stable status.Therefore, this device is together in series the wire rope of bridge floor loop wheel machine left and right sides hoist engine (or hoist engine of different bridge floor loop wheel machines) by turning to fixed pulley, then steel case beam is in the process of hoisting, two suspenders will be regulated the suspension centre left and right sides discrepancy in elevation automatically by turning to fixed pulley, make two suspension centres mutual balanced lifting load simultaneously, two hoist engines after the series connection are equivalent to add an equalizer bar between two suspension centres, have realized the self-balancing of bridge floor loop wheel machine suspender.And solved many 4 of bridge floor loop wheel machines and lifted jointly under the working condition of steel case beam, met 3 principles that determine a plane in the lifting process, realized " 4 liftings, 3 balances ".This device both had been applicable to that separate unit loop wheel machine left and right sides suspender connected the connection that also is applicable between two bridge floor loop wheel machines of different model suspender.
The beneficial effects of the utility model: carry out steel case beam lifting operation at the bridge floor loop wheel machine, when particularly many loop wheel machine multiple spots lifted operation, effect was especially obvious, and difficulty of construction reduces greatly, security risk obviously reduces.
