Description
Technical field
The utility model relates to the hanging device in science of bridge building, relates in particular to the hanging device in steel arch bridge incremental launching construction process.
Background technology
During steel arch bridge incremental launching construction, temporary supporting steel member generally can be set to increase the stability of steel arch, at the pushing tow Liang Houzai that falls, remove.Because of steel arch bridge now with by pushing tow to river course, on bridge, under bridge, all cannot directly use the weight-lifting equipments such as orthodox car hangs, crawler crane to construct, and may be because the use of crane barge, without navigation condition, also limited in construction section.So the Demolition Construction of pushing tow temporary supporting part will be difficult to carry out.
Utility model content
The purpose of this utility model is to provide a kind of hanging device of removing use for pushing tow temporary supporting part, and it can solve and cannot use a difficult problem of removing steel arch bridge pushing tow temporary supporting under traditional crane hoisting equipment condition.
For solving the problems of the technologies described above, the utility model provides a kind of hanging device of removing use for pushing tow temporary supporting part, be characterized in, comprise main winch, secondary winch, the first fixed pulley, the second fixed pulley, the 3rd fixed pulley and the 4th fixed pulley, main, secondary winch is separately fixed on bridge floor, the first fixed pulley, the 3rd fixed pulley is individually fixed on the bridge floor of below of pushing tow temporary supporting part to be removed, the second fixed pulley, the 4th fixed pulley is separately fixed at steel arch below, the rope of main winch is through first, the second fixed pulley ties up to the upper end of pushing tow temporary supporting part to be removed, the rope of secondary winch is through the 3rd, the 4th fixed pulley ties up to the lower end of pushing tow temporary supporting part to be removed.
Described hanging device, its further feature is, and first, second fixed pulley is corresponding at vertical direction each other, and the 3rd, the 4th fixed pulley is corresponding at vertical direction each other.
Described hanging device, its further feature is that pushing tow temporary supporting part to be removed, major and minor winch and each fixed pulley are in same perpendicular.
The utility model is by the ingenious combination of bridge top sheave group and winch, formed a set of equipment that can control hoisting and hanging on bridge, it is convenient, simple to operate that this equipment is installed, can fine solution cannot use under the condition of traditional crane hoisting equipment, remove a difficult problem for steel arch bridge pushing tow temporary supporting.
Accompanying drawing explanation
The above and other feature of the present utility model, character and advantage become more obvious by the description by below in conjunction with drawings and Examples, wherein:
Fig. 1 is the working state figure of the hanging device for pushing tow temporary supporting part dismounting use of an embodiment of the utility model.
The specific embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is described in further detail; set forth in the following description more details so that fully understand the utility model; but the utility model obviously can be implemented with the multiple alternate manner that is different from this description; those skilled in the art can do similar popularization, deduction according to practical situations without prejudice to the utility model intension in the situation that, therefore should be with the content constraints of this specific embodiment protection domain of the present utility model.
In aftermentioned embodiment, the cut length after the segmented cutting that mainly refers to interim steel pipe strut member wait the pushing tow temporary supporting part of removing.
As shown in Figure 1, the hanging device of removing use for pushing tow temporary supporting part comprises main winch 1, secondary winch 2, the first fixed pulley 21, the second fixed pulley 22, the 3rd fixed pulley 23 and the 4th fixed pulley 24, main, secondary winch 1, 2 are separately fixed on bridge floor 3, the first fixed pulley 21, the 3rd fixed pulley 23 is individually fixed on the bridge floor 3 of below of pushing tow temporary supporting part 5 to be removed, the second fixed pulley 22, the 4th fixed pulley 24 is separately fixed at steel arch 4 belows, the rope 11 of main winch 1 is through first, the second fixed pulley 21, 22 tie up to the upper end of pushing tow temporary supporting part 5 to be removed, the rope 12 of secondary winch 2 is through the 3rd, the 4th fixed pulley 23, 24 tie up to the lower end of pushing tow temporary supporting part 5 to be removed.
In preferred embodiment, first, second fixed pulley 21,22 is corresponding at vertical direction each other, and the 3rd, the 4th fixed pulley 23,24 is corresponding at vertical direction each other.
In preferred embodiment, pushing tow temporary supporting part 5 to be removed, major and minor winch 1,2 and each fixed pulley 21,22,23,24 are in same perpendicular.
During construction, rope 11 bands of the main winch 1 of sections to be removed upper end are tight, and the rope of the secondary winch 2 in lower end to be removed is slightly with tightly.Manually complete the cutting of steel pipe sections, and carry out again hoisting and hanging operation after withdrawing.Operate major and minor winch 1,2 and coordinate the steel pipe sections cutting off (pushing tow temporary supporting part 5) is hung out, set level, and under be put on bridge floor.Then follow the prescribed rules, from top to bottom all the other steel pipe supports of cutting disassembling.
The lift heavy of main winch preferably meets the weight of the maximum pushing tow temporary supporting part of 1.5 times, and the lift heavy of secondary winch preferably meets the weight of the maximum pushing tow temporary supporting part of 1 times.
The conventional accessory of other liftings in previous embodiment can, by welding or hole formation, not describe in detail again such as hanger or lifting hole(eyelet) etc.
The rope of winch can be steel rope or other high-intensity flexible elements in addition.
Although the utility model with preferred embodiment openly as above, it is not for limiting the utility model, and any those skilled in the art, within not departing from spirit and scope of the present utility model, can make possible change and modification.Therefore, every content that does not depart from technical solutions of the utility model, any modification, equivalent variations and the modification above embodiment done according to technical spirit of the present utility model, within all falling into the protection domain that the utility model claim defines.
