Description
Technical field
This utility model relates to technical field of building construction, especially relates to a kind of urban rail U-shaped Liangmen sling device.
Background technology
For large-scale precast beam, the general prefabrication of beam that first completes in beam field, then carry out lifting movement.During beam body lifting, it is necessary to meet four-point hoisting three-point balancing principle, to ensure beam body stress balance, prevent by twisting force in hoisting process, have influence on bridge quality.Traditional precast beam suspender is generally gantry crane, it is provided with two unrelated suspension centres, smoothly common precast beam can be lifted by crane, but for the U-shaped beam of urban rail that profile is the most special, it is only capable of meeting 4 liftings, to accomplish 3 balances, need repeatedly to adjust, wasting time and energy, and beam body is difficult to keep poised state, therefore common precast beam suspender is not suitable for lifting the U-shaped beam of urban rail.Additionally, urban rail U-shaped beam beam type is complicated, beam body width is by 5.2m to 5.6m, need the suspender of supporting Multiple Type and it needs to be replaced between different suspenders, cause the waste of human and material resources, and working performance is the lowest, it is impossible to meet the requirement of factorial construction progress in beam field.
Summary of the invention
This utility model provides a kind of urban rail U-shaped Liangmen sling device, it is therefore intended that solve the problem that tradition precast beam suspender is not suitable for lifting the U-shaped beam of urban rail.
For achieving the above object, this utility model can take following technical proposals:
Urban rail described in the utility model U-shaped Liangmen sling device, including gantry crane, first quiet pulley, the second quiet pulley being symmetrically distributed in described first quiet pulley both sides and the 3rd quiet pulley are installed on described gantry crane crossbeam, and are positioned at the first rolling-up mechanism above described second quiet pulley and the 3rd quiet pulley and the second rolling-up mechanism；There is horizontal connector by steel wire hang below gantry crane crossbeam, described horizontal connector is hinged with the 4th quiet pulley and the 5th quiet pulley respectively；Described steel wire rope is drawn from described first rolling-up mechanism, draw from the 4th Jing Hualunchu after the some circles of described second quiet pulley and the 4th quiet pulley form laborsaving assembly pulley, around to the 5th Jing Hualunchu after the first quiet pulley, form laborsaving assembly pulley further around the some circles of the 5th quiet pulley and the 3rd quiet pulley, and be connected to described second rolling-up mechanism after the 3rd quiet pulley is drawn；Two groups of lifting blocks being provided with suspension rod it are hinged with respectively bottom described horizontal connector.
Longitudinally spaced bottom described horizontal connector being welded with multiple hanger, connecting rod and the hanger of described lifting block are flexibly connected by latch.
The urban rail U-shaped Liangmen sling device that this utility model provides, only need to tradition suspender on the basis of simple refit the most available, the beam body balance adjustment process of complexity is needed not move through when for lifting urban rail U-shaped beam, the lifting requirements of four-point hoisting three-point balancing can be met, greatly reduce suspender cost of manufacture, improve lifting efficiency simultaneously；By the lifting block being movably connected with horizontal connector, suspender spacing can be conveniently adjusted, meet the lifting requirements of the U-shaped beam of polytype urban rail.This utility model simple in construction, with low cost, easy to use, be suitable to the lifting of polytype urban rail U-shaped beam, it is not necessary to be equipped with and overlap suspender more, decrease and change the human and material resources that different suspender is spent, improve work efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A portion enlarged drawing in Fig. 1.
Detailed description of the invention
As shown in Figure 1, 2, urban rail described in the utility model U-shaped Liangmen sling device, including gantry crane, first quiet pulley 2 is installed on gantry crane crossbeam 1, is symmetrically distributed in the second quiet pulley 3 and the 3rd quiet pulley 4 of the first quiet pulley 2 both sides, and be positioned at the first rolling-up mechanism 5 and the second rolling-up mechanism 6 above the second quiet pulley 3 and the 3rd quiet pulley 4；It is hung with horizontal connector 8 by steel wire rope 7 below gantry crane crossbeam 1, horizontal connector 8 is hinged with the 4th quiet pulley 9 and the 5th quiet pulley 10 respectively；Described steel wire rope 7 is drawn from the first rolling-up mechanism 5, enclose around the second quiet pulley 3 and the 4th quiet pulley 9 one and draw at the 4th quiet pulley 9 after partly forming laborsaving assembly pulley, around at the 5th quiet pulley 10 after the first quiet pulley 2, enclose further around the 5th quiet pulley 10 and the 3rd quiet pulley 4 one and partly form laborsaving assembly pulley, and be connected to the second rolling-up mechanism 6 after the 3rd quiet pulley 4 is drawn.Two lifting blocks 12 being provided with suspension rod 11 it are hinged with respectively bottom horizontal connector 8.
For meeting the lifting demand of the U-shaped beam of different in width urban rail 16, bottom horizontal connector 8, the most longitudinally spaced 10cm in two ends is welded with five hangers 13, and the connecting rod 14 of each lifting block 12 all can be movably connected by latch 15 with hanger 13.Therefore, it can the link position by changing connecting rod 14 and hanger 13, it is achieved lifting width is at the U-shaped beam of urban rail 16 of 5.2-5.6m.
During use, as it is shown in figure 1, according to the width of the U-shaped beam of urban rail 16, select the hanger 13 of correct position to be attached with lifting block 12 connecting rod 14.Make suspension rod 11 pre-manufactured hole through urban rail U-shaped beam 16 two ends of lifting block 12, and install steel washer additional in end and nut makes the U-shaped beam of urban rail 16 link together, so that the U-shaped beam of urban rail 16 is with horizontal connector 8 synchronous hoisting and whereabouts with lifting block 12.Walk around the first quiet pulley 2 due to steel wire rope 7 and be associated with horizontal connector 8 two ends, therefore the first rolling-up mechanism 5 is or/and the second rolling-up mechanism 6 is to making steel wire rope 7 carry out rolling or Shu Fangshi, urban rail U-shaped beam 16 two ends can easily keep poised state, meets lifting requirements.During the lifting U-shaped beam 16 of urban rail, first pass through the first rolling-up mechanism 5 or/and the folding and unfolding action to steel wire rope 7 of second rolling-up mechanism 6, carry out the poised state preconditioning of the U-shaped beam of urban rail 16, afterwards, make the first rolling-up mechanism 5 and the second rolling-up mechanism 6 rolling steel wire rope 7 simultaneously, complete the lifting of the U-shaped beam of urban rail 16, when the U-shaped beam of urban rail 16 moves to correct position, first rolling-up mechanism 5 and the second rolling-up mechanism 6 relax simultaneously and put steel wire rope 7, make the U-shaped beam of urban rail 16 fall.
