Abstract
The invention discloses a mobile lifting bracket for building a bridge. The mobile lifting bracket is characterized by comprising a truss structure (1), a beret piece (2), a walking device (3) and a winch (4) and is characterized in that the beret piece (2) is mounted on the top surface of the truss structure (1); the walking device (3) is mounted at the bottom of the truss structure (1); and the winch (4) is mounted at the tail part of the truss structure (1). The mobile lifting bracket for building the bridge, disclosed by the invention, has finite operation positions on the surface of the bridge when being mainly used for building the bridge, can be assembled and disassembled on the bridge surface and can freely move in a lifting position; the lifting position of the lifting bracket can be changed according to construction needs; and the length of a lifting arm of the lifting bracket can be also changed to satisfy various lifting requirements.
Description
Technical field
The present invention relates to a kind of bridge and build the mobile hoisting support, belong to technical field of bridge engineering.
Background technology
In the prior art, when constructing a bridge, traditional cantilever hanger device is fixed on the bridge floor usually, is used for hoisting heavy from ground to the bridge floor, and uses hoisting bracket top mobile formula crossbeam that weight is moved to bridge floor.The characteristics of this method are: 1, need be at the built-in fitting of the pre-buried heavy steel plate of bridge floor as the cantilever suspension bracket; 2, the installation of cantilever suspension bracket is to loose to piece together operation, stretches out the bracketed part installation of bridge floor and remove all to exist work high above the ground, construction safety to be difficult to assurance; 3, the cantilever suspension bracket can only be installed in the beam section 0 ~ No. 1; Require the following levelling of the land of bridge floor broad; The job site poor for some orographic conditions, that the place is narrow and small must spend expensive construction job platform, guarantees that the suspension cable that large-scale haulage vehicle loads about 30T can pass through in the above; 4, owing to be the fixed boom suspension bracket, setting is limited dumb; 5, the hoisting bracket size need be confirmed according to weight appearance and size and weight, and the resuspended more arm suspension bracket of object appearance and size is big more, and the structure of hoisting bracket is heavier.
Summary of the invention
The objective of the invention is to: provide a kind of bridge to build the mobile hoisting support.Can solve the limitation of traditional cantilever suspension bracket, " fixed " changed into " movable type ", can move to any lifting position during use flexibly; Can be on bridge installing/dismounting, mounting or dismounting are fast simple; Change jib-length according to the construction needs, and can lift by crane the object that is several times as much as dead weight, receive the place restriction little, to remedy the deficiency of prior art.
The present invention constitutes like this: comprise trussed construction, shellfish thunder sheet, running gear and hoist engine, it is characterized in that: shellfish thunder sheet is installed on the trussed construction end face, and running gear is installed in the trussed construction bottom, and trussed construction, hoist engine are installed on the trussed construction afterbody.
Above-mentioned trussed construction afterbody is provided with the counterweight platform, and the counterweight platform is used to place balancing weight.
Above-mentioned running gear is made up of road wheel and movable motor.
Above-mentioned shellfish thunder sheet front end is installed assembly pulley.
Above-mentioned shellfish thunder sheet utilizes trussed construction and balancing weight locking.
Compared with prior art, main feature of the present invention is: 1, the mobile hoisting support is creationary is designed to " movable type " with tradition " fixed "; 2, can on bridge floor, be dragged to the position that needs use after the installation more arbitrarily, tow back to bridge floor after being used to complete again and remove, solve the risk that the high-altitude is installed and removed; 3, owing to can move, do not receive the restriction in place, can satisfy the lifting requirements under any condition of bridge floor; 4, owing to be removable, setting is flexible.Particularly lift main equipments such as mobile crane when lifting bridge floor, can rise in cable stayed bridge bridge floor dead ahead and winch to the bridge floor absolute altitude, move inwardly into bridge floor and get final product.Traditional method must be in the lifting of bridge leg, lifts to the bridge floor absolute altitude, moves on to bridge floor from middle the passing of two skew cables after crane is turn 90 degrees, and construction is complicated; 5, this mobile hoisting support Design is passed through optimal design, thereby utilizes balancing weight to do structure itself small and exquisite, can lift by crane the weight (5 ~ 10 times) that is several times as much as dead load itself simultaneously again; 6, can be according to construction needs temporary variations jib-length, the weight of the group number lifting Different Weight of increase and decrease shellfish thunder sheet can satisfy various lifting demands; 7, in construction, have easy to operate, mounting or dismounting fast, characteristics such as flexible and efficient.
Description of drawings
Accompanying drawing 1 is structural representation of the present invention;
Accompanying drawing 2 is front schematic view of the present invention.
Be labeled as in the accompanying drawing: 1-trussed construction, 2-shellfish thunder sheet, 3-running gear, 4-hoist engine, 5-counterweight platform, 6-balancing weight, 7-road wheel, 8-movable motor, 9-assembly pulley
The specific embodiment
As depicted in figs. 1 and 2; Heavy 5 of trussed construction 1 afterbody establishing and hoist engine 4, trussed construction 1 top are installed shellfish thunder sheet 2, and shellfish thunder sheet 2 utilizes finish rolling screw thread and trussed construction 1 locking; Running gear 3 is installed in trussed construction 1 bottom; Running gear 3 is walked through road wheel 7 in orbit, and shellfish thunder sheet 2 front ends are equipped with assembly pulley 9, and extraction rope gets into hoist engine 4 through assembly pulley 9 cablings.Trussed construction 1 is main force structure; The counterweight platform 5 of afterbody is placed balancing weight 6 according to lifted weight; Be used for the lift heavy that balance shellfish thunder sheet 2 bears; According to the shellfish thunder sheet of different lift heavys installation varying numbers, shellfish thunder sheet 2 can satisfy various lifting demands at the horizontal flexible transformation hoisting point position of trussed construction 1 end face simultaneously.
During use, confirm the general quality and the size of weight earlier, adjust the weight of shellfish thunder sheet 2 and balancing weight 6 then, to ensure its safety; During lift heavy extraction rope is fixed in weight, through the driving of hoist engine 4 weight is sling, after weight reached necessary height, hoist engine 4 stopped, and movable motor 8 ground-engaging wheels 7 move through track, and the safety place that weight is transferred to appointment puts down.
