Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of beam bridge floor hogging moment tensioning trolley device,
Including support plate 1, it is provided with pillar 2 at left and right sides of the bottom of the support plate 1, the bottom of the pillar 2 is provided with pedestal
3, the bottom four corners of the pedestal 3 are mounted on idler wheel 4, and the top center of the support plate 1 offers T-slot 5, described
The inner cavity top of T-slot 5 is inlaid with bearing 6, and the inner cavity of the bearing 6 is inlaid with pivoted housing 7, the right hand top weldering of the pivoted housing 7
It is connected to swing arm 8, activity is plugged with spacer pin 9 in the swing arm 8, and the uniform circumferential direction in top of the support plate 1 is offered and limited
The compatible limit hole 10 of pin 9, through there is screw rod 11 in the pivoted housing 7, and screw rod 11 is threadedly coupled with pivoted housing 7, the screw rod
11 bottom is welded with rectangle supporting table 12, and it is very heavy that the top left side of the rectangle supporting table 12 is equipped with prestressed stretch-draw
Top 13.
It wherein, is to be welded and fixed between the support plate 1, pillar 2 and pedestal 3, stable connection, the support plate 1, branch
Column 2, pedestal 3, pivoted housing 7, swing arm 8, spacer pin 9, screw rod 11 and rectangle supporting table 12 are high-strength alloy steel construction, intensity
