Detailed Description
As shown in fig. 1, the utility model relates to a river course deep basal pit construction dust keeper, including relative two fixed frames, first steel strand wires 7, dustproof cloth 6 and the motor 10 that set up in the foundation ditch both sides. Every fixed frame all includes a stand 1 and a horizontal positioning pole 5 of being connected with stand 1, and horizontal positioning pole 5 is the square steel pipe, and stand 1 is fixed to be set up on the basis of foundation ditch, and horizontal positioning pole 5 is fixed to be set up on the top of stand 1, horizontal positioning pole 5 parallel distribution among two fixed frames.
Two fixed frames are arranged on two sides of the foundation pit in a left-right mode, the fixed frame close to the motor 10 is a fixed frame on the left side, and the fixed frame far away from the motor 10 is a fixed frame on the right side. All be provided with on two fixed frame and supply first steel strand wires 7 to encircle the complex assembly pulley, the assembly pulley includes first fixed pulley 4 and second fixed pulley 2, and first fixed pulley 4 sets up on the horizontal position pole 5 of stand 1 and horizontal position pole 5 junction, and second fixed pulley 2 sets up on the cylinder of stand 1. Be connected with reel 11 on the motor 10, first steel strand wires 7 are around establishing on reel 11, and first steel strand wires 7 extend from reel 11 and back in proper order around establishing on left side fixed frame's first fixed pulley 4, on right side fixed frame's second fixed pulley 2, on left side fixed frame's second fixed pulley 2, are connected with reel 11 again at last, and motor 10 drive reel 11 rotates and then drives first steel strand wires 7 and rotate.
The two ends of the horizontal positioning rod 5 are respectively provided with a third fixed pulley 3, a second steel strand 8 is wound between two corresponding third fixed pulleys 3 on the two horizontal positioning rods 5, the second steel strand 8 forms a closed annular loop between the two third fixed pulleys 3, and the two second steel strands 8 are distributed on the two sides of the first steel strand 7 in parallel.
