Change, solve the problem disassembled with installation difficulty；
2) evade blue-collar security risk in work high above the ground, eliminate the high-risk operation of artificial fixing twisted seat；
3) greatly reduce workload, decrease cost payout, improve working performance, it is ensured that become the safety across construction steady
Qualitative, and this device is small, simple in construction, it is simple to safeguard and adjust, reducing manufacture difficulty.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of Bridge Erector flexible leg twisted seat temporary fastening device described in the utility model.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings:
As it is shown in figure 1, this utility model one Bridge Erector flexible leg twisted seat temporary fastening device, Bridge Erector nose girder 9 leads to
Cross connected free bearing 8 and pin 7 flexibly connect with nose girder front leg strut 6, temporary fastening device include fixing seat 1, screw rod 2,
Adjusting nut 4 and support bar 5, fixing seat 1 is fixing with nose girder front leg strut 6 to be connected, and screw rod 2 is fixed with fixing seat 1, support bar 5
Lower end is connected with screw rod 2 by adjusting nut 4, and the upper end of support bar 5 is arranged on the lower section of free bearing 8, and fixing seat 1 is led for being welded on
The steel plate of beam front leg strut 6, fixing seat 1 is provided with through hole, and the upper end of screw rod 2 passes through hole and by fixing nut 3 with fixing
Seat 1 is the most fixing to be connected, and adjusting nut 4 is Double-ended nut, and the female thread of the first end of adjusting nut 4 is left hand thread, adjusts
The female thread of the second end of nut 4 is right-handed thread, and the upper end of screw rod 2 and the lower end of support bar 5 are respectively arranged with and adjust spiral shell
The external screw thread that the two ends of female 4 are corresponding, the middle part of adjusting nut 4 is provided perpendicular to the stress hole that screws of its axis, support bar 5
For toggle-action lever, and fixing seat 1, screw rod 2, adjusting nut 4 and support bar 5 quantity are two, respectively along the axis pair of free bearing 8
Claim the both sides being distributed in nose girder front leg strut 6.
The operation principle of this utility model a kind of Bridge Erector flexible leg twisted seat temporary fastening device is as follows:
Become as a example by into 24 meters of constructions by DF900D Bridge Erector 32 meters, as it is shown in figure 1, Bridge Erector is in 32 meters of span location
Time, when needs become when into 24 meters, auxiliary screwing device is inserted into and screws in stress hole in the middle part of adjusting nut 4, then lead to
Crossing to pull assists screwing device to make adjusting nut 4 rotate, because the female thread at screw on nut two ends is oppositely oriented, adjusts so rotating
During whole nut 4, the distance between screw rod 2 and support bar 5 can be made to increase or reduce, by screwing adjusting nut 4, regulating support
The height of bar 5, makes the upper end of support bar 5 be resisted against the both sides of downside of free bearing 8, thus define pin 7 rotate from by
Degree, it is achieved that the interim of free bearing 8 is fixed so that it is form rigid structure with nose girder front leg strut 6.
Then disassembling the connecting bolt between free bearing 8 and Bridge Erector nose girder 9, mobile above-mentioned rigid structure is to 24 meters of spans
Position, connect and fasten the bolt between free bearing 8 and Bridge Erector nose girder 9, the most again rotate adjusting nut 4, make support bar 5
Declining, and arrange certain space between free bearing 8, thus recover the flexible structure of nose girder front leg strut 6, Bridge Erector is normally set a roof beam in place.
Thus realize in whole leg location conversion process, substantially reduce workload, add become across security and stability.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, every according to skill of the present utility model
The technology deformation that art scheme is made, within each falling within protection domain of the present utility model.
