The height on jin top and position.This operating method has the following disadvantages: that 1, personnel station operating space on platform is narrow, time-consuming to take
Power；2, it needs to put into more hoisting machinery and labour；3, construction operation low efficiency；4, the height Adjustment precision of stretch-draw jack
It not can guarantee, position can not be fixed.
Summary of the invention
The purpose of this utility model, which is that, overcomes above-mentioned the deficiencies in the prior art, and provides a kind of for coagulation
The regulating device of native cast-in-situ box girder tensioning, the regulating device can be accurately positioned height and the position of stretch-draw jack.
As above design, the technical solution of the utility model is: a kind of regulating device for concrete cast-in-situ box girder tensioning,
It is characterized by comprising platform, four platform legs and gallows frames；Four platform legs are respectively welded at platform
Quadrangle；The gallows frame is welded on platform, and stretch-draw jack is hung on gallows frame；The platform leg includes bottom
Portion's standpipe, height adjusting screw rod, DOCK LEVELER and universal wheel, height adjusting screw rod penetrate in the standpipe of bottom, bottom end welding
Universal wheel, height adjusting screw rod are supported with bottom standpipe joint mounting height adjustable plate.
Above-mentioned platform uses round steel platform.
Above-mentioned stretch-draw jack is hung on gallows frame by U-shaped buckle and iron chains.
Above-mentioned bottom standpipe is made of standpipe upper section and standpipe the lower section welded connecting of different-diameter.
Above-mentioned DOCK LEVELER is by being threadedly mounted to height adjusting screw rod and bottom standpipe joint.
The utility model has the following advantages and good effect:
1, the utility model structure can the free scrolling realization stretch-draw jack on operation platform by four universal wheels
Horizontal position positioning and fine tuning；Height adjusting screw rod stretching outside the standpipe of bottom is completed by rotation DOCK LEVELER, it is real
The vertical height of existing stretch-draw jack is adjusted；It is hung on gallows frame by U-shaped buckle and iron chains, realizes that stretch-draw jack is perpendicular
Fine tuning to tilt angle.Therefore, the utility model is suitable for post-stressed steel Shu Zhangqian on the downside of concrete cast-in-situ box beam
The height on jin top and the adjusting of horizontal position and the fine tuning at vertical inclination angle, and positioning accuracy can be guaranteed, position can be fixed.
2, the utility model is easy to operate, can save labour and lifting equipment, improves labor efficiency.

Standpipe upper section and standpipe lower section be welded to connect bottom standpipe, height adjusting screw rod, DOCK LEVELER and the universal wheel of composition, it is high
Degree adjusting screw rod penetrates in the standpipe of bottom, and universal wheel is welded in bottom end, and height adjusting screw rod and standpipe lower section joint pass through silk
Mounting height adjustable plate is detained to support bottom standpipe, to make DOCK LEVELER can be in height adjusting screw rod length model by screw thread
Enclose interior rotary moveable.
The operating process of the utility model is:
1, round steel platform is used by welding and bottom standpipe upper section and is welded to connect；
2, gallows frame and round steel platform welding are fixed；
3, stretch-draw jack is hung on gallows frame by U-shaped buckle and iron chains；
4, by height adjusting screw rod one end and universal wheel using welded connecting；
5, height adjusting screw rod is penetrated to the lower section and upper section of bottom standpipe；
6, universal wheel regulating device assembled above is placed on operation platform, and stretch-draw jack is hung on into iron chains
On；
7, by four universal wheels can freely on operation platform the positioning of scrolling realization stretch-draw jack horizontal position and
Fine tuning；
8, it is flexible outside the standpipe of bottom that height adjusting screw rod is completed by rotation DOCK LEVELER, realizes tensioning thousand
Jin top vertical height is adjusted；
9, it is hung on gallows frame by U-shaped buckle and iron chains, realizes the fine tuning of the vertical tilt angle of stretch-draw jack；
10, regulating device can successively remove device according to above-mentioned after having used in proper order.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
