Rolling type three station cofferdams
Technical field
The present invention relates to waterproof field, underground building, particularly relate to a kind of rolling type three station cofferdams.
Background technology
At present, the measure that the underground building waterproof is poured in down a chimney is generally: design in advance marks water level, the step or the slope of certain altitude are set at the place, access, the anti-groove that floods perhaps is set in the access, and be furnished with and the anti-supporting anti-plate that floods of groove that floods, when water level surpasses the mark water level of design in advance, will prevent flooding plate by the special messenger and insert the anti-groove that floods, form the anti-baffle plate that floods.
There is following shortcoming in above-mentioned measure:
(1) step or slope are set after, the absolute altitude of the ground level of underground structure itself, surrounding buildings thing and road all will recomputate, and has increased designer's workload;
(2) prevent that flooding baffle plate needs the special messenger to keep an eye on, when entering the mouth more for a long time, need a large amount of manpowers be distributed to each inlet, human cost is higher, and the dash height is also dumb, is difficult in time, synchronously bring into play waterproof effect.
Summary of the invention
The objective of the invention is in order to overcome the deficiency of above-mentioned background technology, a kind of rolling type three station cofferdams are provided, can prevent that ground rainwater from pouring into the underground building, do not influence people and vehicle again and normally pass in and out the underground structure, also do not influence absolute altitude to ground level, surrounding buildings thing and the road of underground building itself, need not to recomputate, reduced designer's workload; Automaticity is higher, and the dash high flexible can be in time, waterproof synchronously, reduces human cost, and simple in structure, durability is strong, and easy construction is cheap, is convenient to maintenance.
Rolling type three station cofferdams provided by the invention, comprise first cylinder, second tin roller, wire rope, first flash board, second flash board, reducing motor, first chute, two threshold seats, weight, the float rotation axle and second chute, described reducing motor links to each other with first cylinder, first cylinder and second tin roller are arranged side by side, the below of first cylinder vertically is provided with first chute, the below of second tin roller vertically is provided with second chute, first chute, second chute below respectively is provided with the threshold seat of a hollow, the below of threshold seat is provided with float rotation axle, one end of wire rope is fixedlyed connected with first cylinder, wire rope is arranged along first chute, pass the threshold seat of first chute below, walk around float rotation axle, pass the threshold seat of second chute below, arrange that along second chute other end of wire rope is wound on the second tin roller; Be fixed with first flash board and second flash board on the wire rope.
On the basis of technique scheme, the below of described float rotation axle is provided with weight, and weight is fixedlyed connected with float rotation axle.
On the basis of technique scheme, described first flash board, second flash board adopt all that steel plate is hinged to be made.
On the basis of technique scheme, the equal integral body of external surface of described first flash board, second flash board is coated with rubber strip.
Compared with prior art, advantage of the present invention is as follows:
(1) when the water level of ground rainwater surpasses the ultimate design absolute altitude that pours in down a chimney the underground building, flexible step of the present invention lifting successively, can prevent that ground rainwater from pouring into the underground building, do not influence people and vehicle again and normally pass in and out the underground structure, also do not influence absolute altitude to ground level, surrounding buildings thing and the road of underground building itself, need not to recomputate, reduced designer's workload.
(2) the present invention adopts Electric Drive to realize Long-distance Control, and automaticity is higher, and the dash high flexible can in time, synchronously be brought into play waterproof effect, and reduces human cost.
(3) drive mechanism of the present invention is simple, and durability is strong, and easy construction is cheap.
(4) critical piece of the present invention is a standard component, changes easily, is convenient to maintenance.

The specific embodiment
The present invention is described in further detail below in conjunction with drawings and the specific embodiments.
Referring to shown in Figure 1, the embodiment of the invention provides a kind of rolling type three station cofferdams, comprise first cylinder 1, second tin roller 2, wire rope 3, first flash board 4, second flash board 5, reducing motor 6, first chute 7, two threshold seats 8, weight 9, the float rotation axle 10 and second chute 11, reducing motor 6 links to each other with first cylinder 1, first cylinder 1 is arranged side by side with second tin roller 2, the below of first cylinder 1 vertically is provided with first chute 7, the below of second tin roller 2 vertically is provided with second chute 11, first chute 7, second chute, 11 belows respectively are provided with the threshold seat 8 of a hollow, the below of threshold seat 8 is provided with float rotation axle 10, the below of float rotation axle 10 is provided with weight 9, and weight 9 is fixedlyed connected with float rotation axle 10.
One end of wire rope 3 is fixedlyed connected with first cylinder 1, wire rope 3 is arranged along first chute 7, pass the threshold seat 8 of first chute, 7 belows, walk around float rotation axle 10, pass the threshold seat 8 of second chute, 11 belows, arrange that along second chute 11 other end of wire rope 3 is wound on the second tin roller 2.Reducing motor 6 drives first cylinder 1 and rotates, and first cylinder 1 drives second tin roller 2 backward rotation by wire rope 3.
Be fixed with first flash board 4 and second flash board 5 on the wire rope 3, first flash board 4, second flash board 5 adopt all that steel plate is hinged to be made, the equal integral body of external surface of first flash board 4, second flash board 5 is coated with rubber strip, and rubber strip plays sealing function.Weight 9 is regulated first flash board 4, the tension force of second flash board 5 and the pressure of threshold seat 8 automatically.
The operating principle of the embodiment of the invention is elaborated as follows:
In the embodiment of the invention rolling type three station cofferdams be provided with waterproof at the feeder connection place, close, current three kinds of stations, the operating principle of three kinds of stations is described respectively below.
Referring to illustrated in figures 1 and 2, when rolling type three station cofferdams are in waterproof state, second tin roller 2 clockwise rotates automatically, Wound steel rope 3, wire rope 3 drives first flash board 4 and moves earthward, be pressed in up to first flash board 4 on the threshold seat 8 of first chute, 7 belows, second tin roller 2 stops Wound steel rope 3, and weight 9 makes 4 tensionings of first flash board all the time and presses the threshold seat 8 of first chute, 7 belows.
Referring to Fig. 3 and shown in Figure 4, when rolling type three station cofferdams were in closed condition, second flash board 5 was used as rolling-gate.Reducing motor 6 drives first cylinder 1 and clockwise rotates, and first cylinder 1 drives second tin roller 2 backward rotation by wire rope 3.Wire rope 3 drives second flash board 5 and moves earthward, be pressed in up to second flash board 5 on the threshold seat 8 of second chute, 11 belows, first cylinder 1 just stops Wound steel rope 3, and weight 9 makes 5 tensionings of second flash board all the time and presses the threshold seat 8 of second chute, 11 belows.
Referring to Fig. 5 and shown in Figure 6, when rolling type three station cofferdams are in the state of passing through,
First flash board 4 is wound on first cylinder 1, and second flash board 5 is wound on the second tin roller 2, and the pedestrian can be by inlet, and weight 9 makes wire rope 3 keep tensioning state all the time.
Those skilled in the art can carry out various modifications and variations to the embodiment of the invention, if these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then these modifications and modification are also within protection scope of the present invention.
