Embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Referring to attached drawing 1, a kind of mobile guardrail of bridge construction, is mainly used for preventing construction site from falling from high altitude thing occurs
Therefore it includes guardrail rack 1 and footing 2, guardrail rack 1 is welded and fixed with footing 2, and mobile guardrail is overall by 2 stable frame of footing
On ground, dangerous matter sources and Field Force can be kept apart, improve working security.
Above-mentioned footing 2 is symmetrically arranged with two groups, and the overall domed structure of footing 2 on mobile guardrail length direction；It is logical
Cross and footing 2 is arranged to domes so that footing 2, in 2 points of supports, can not only improve mobile guardrail entirety with ground
Stability, and the possibility of mobile guardrail rollover can be reduced.
Referring to attached drawing 1, above-mentioned guardrail rack 1 is formed using steel-pipe welding anyhow staggeredly, its downside is welded with bottom bar
3, bottom bar 3 is in horizontally disposed；To further improve the stability of mobile guardrail, by being mounted with clump weight 4 on bottom bar 3,
And the clump weight 4 is axially and symmetrically equipped with two groups along bottom bar 3.
By setting clump weight 4 on bottom bar 3, the center of gravity of mobile guardrail is reduced, so as to effectively improve the steady of mobile guardrail
It is qualitative；Meanwhile when guardrail rack 1 is impacted, clump weight 4 can speed up mobile guardrail and quickly restore balance.
Referring to attached drawing 1, cross bar 5 is welded with guardrail rack 1, cross bar 5 is in horizontally disposed；Cross bar 5 is located substantially at movement
The support component 6 for being used to support mobile guardrail is connected with 1/2 height and position of guardrail, and on cross bar 5, support component 6 includes branch
Strut 7 and abutting block 8.
With reference to attached drawing 2, supporting rod 7 includes telescopic rod 71 and loop bar 72, and telescopic rod 71 sets in grafting with loop bar 72, stretches
The one end of bar 71 away from loop bar 72 and above-mentioned cross bar 5 are hinged, and the one end of loop bar 72 away from telescopic rod 71 then with above-mentioned abutting block 8
In hinged setting；Compression spring 73 is arranged with telescopic rod 71, the both ends of compression spring 73 push against telescopic rod 71 and loop bar respectively
72, and normal thread is connected with the fastening bolt 74 for locking telescopic rod 71 on loop bar 72.
To further improve the support effect of support component 6, above-mentioned supporting rod 7 is axially and symmetrically equipped with two groups along cross bar 5；
Meanwhile two it is horizontal between supporting rod 7 be equipped with interlocking bar 9, the both ends of interlocking bar 9 are welded and fixed with two loop bars 72 respectively.
When mobile guardrail stable in placement, supporting rod 7 pushes against ground entirely through block 8 is pushed against；In work, fastening bolt 74
