Detailed description of the invention
Fig. 1 is the utility model structure diagram；
Fig. 2 is the utility model structure diagram；
Fig. 3 is that the utility model C-type steel and door shape support fixed connection structure schematic diagram；
Fig. 4 is partial enlarged view at A in Fig. 1.
Specific embodiment
The utility model is described in detail in 1-4 and specific embodiment with reference to the accompanying drawing.
A kind of movable type foundation pit construction protective device, including be arranged in foundation pit two sides I shape track 1 and be arranged in work
Three on the font track 1 door shape supports 2 being set side by side；The door shape support 2 is by door pillar 2-2 and is fixed on the top door pillar 2-2
The cambered ceiling in portion is constituted, and the cambered ceiling includes the bowst girder 2-1 being fixed at the top of door pillar 2-2；The bowst girder
2-1 is welded to form by curved steel tube parallel up and down by continuous V-type support 3, and the two sides bowst girder 2-1 pass through outer-hexagonal
It is fixedly connected, is welded on the curved steel tube above the bowst girder 2-1 and bowst girder at the top of bolt pair and door pillar 2-2
2-1 parallel mounting plate 2-3；The bottom the door pillar 2-2 is mounted on the idler wheel 4 being arranged in I shape track 1, door pillar 2-2
Top outer is connected with wirerope 5；It is connected between the adjacent segmental crossbeam 2-1 by longitudinally uniformly distributed C-type steel 6, and C-type steel
The bottom at 6 both ends is fixedly connected on mounting plate 2-3 by outer-hexagonal bolt pair, and it is anti-that the top of the C-type steel 6 is covered with iron sheet
Shield 7, and iron sheet shield 7 passes through X-type bracket 8 by rivet between the top of C-type steel 6, the adjacent door pillar 2-2
It is fixed, and door pillar 2-2 upper and lower side and 8 end of X-type bracket are articulated and connected by bolt pair, 8 infall of X-type bracket passes through bolt pair
Articulated connection.
0.937m is divided between the C-type steel 6.
The center of the V-type support 3 is equipped with perpendicular support 3-1.
The iron sheet shield 7 is made of 3mm thickness iron sheet panel lap.
Implementation method:
When foundation pit is very big, and a mobile protection canopy body cannot protect foundation pit completely, can be applied by multiple mobile foundation pits
