[0035] like Figure 1 and Figure 2 as well as Figure 4and Figure 5 As shown, the covering device 7 includes a return frame 71, the return frame 71 is fixedly connected to the upper surface of the base 1, the upper surface of the return frame 71 is fixedly connected to a fixed top plate 72, the upper surface of the return frame 71 is provided with two second slide grooves, the surfaces of the second slide grooves on the two return frames 71 are slidably connected to second sliders 75, and the upper surface of the second sliders 75 is fixedly connected to a movable top plate 74. By providing the return frame 71, the fixed top plate 72 and the movable top plate 74, the groove can be covered, and by providing the second slider 75, the movable top plate 74 can be moved.

[0036] The lower surface of the fixed top plate 72 is fixedly connected with a shielding plate 73, which is fixedly connected to the inner wall of the return frame 71. The upper surface of the fixed top plate 72 is fixedly connected with a second limiting plate 77, and the inner wall of the second limiting plate 77 is threadedly inserted with a limiting screw 78. The upper surface of the movable top plate 74 is fixedly connected with a first limiting plate 76.

By providing the first limiting plate 76, the second limiting plate 77 and the limiting screw 78, the movable top plate 74 and the fixed top plate 72 can be connected.

[0037] Working principle: when connecting the ductile iron pipe using the movable fall chain device for quick installation of the ductile iron pipe, first move the base 1 to the position where the movable fall chain device for quick installation of the ductile iron pipe is required, then adjust the position of the retractable clamp 3 through the retractable lifting platform 2, fix a section of the ductile iron pipe through the retractable clamp 3, connect the ductile iron pipe to be connected and the electric hoist 4 through the control component 5, and then use the electric hoist 4 to control the movement of the ductile iron pipe through the control component 5 to complete the connection work. When it is necessary to use a movable chain device for quick installation of ductile iron pipes, pull the pull plate 610 to drive the limit rod 611 to slide on the inner wall of the fixed plate 609, so that the limit rod 611 moves away from the limit hole on the base 1, releases the restriction on the position of the movable plate 608, moves the movable plate 608 to slide on the surface of the groove on the base 1, thereby controlling the support platform 601 to move away from the base 1, releases the pull plate 610, and under the action of the elastic force of the spring 612, the limit rod 611 moves close to the limit hole on the base 1, restricts the position of the movable plate 608, thereby restricting the position of the support platform 601, places the ductile iron pipe to be connected on the support platform 601, and rotates the control screw 606 to rotate on the inner wall of the arc plate 605, thereby controlling the clamping plate 603 to drive the first sliding block 602 to slide on the surface of the first sliding groove on the support platform 601, so that the two clamping plates 603 and the rubber The plate 604 moves close to the ductile iron pipe to be installed to fix the position of the ductile iron pipe, and the pull plate 610 is pulled to make the limit rod 611 move away from the limit hole on the base 1, so as to release the restriction on the position of the movable plate 608, and move the support platform 601 to make the limit rod 611 move away from the limit hole on the base 1, and release the pull plate 610. Under the action of the elastic force of the spring 612, the pull plate 610 moves close to the fixed plate 609, and then the ductile iron pipe is driven to move by the electric hoist 4. At this time, the "L"-shaped rod 607 slides on the inner wall of the base 1, so as to complete the connection of the ductile iron pipe. By setting the supporting device 6, the ductile iron pipe to be connected can be supported in the process of connecting the ductile iron pipe using the movable fall chain device for quick installation of the ductile iron pipe, thereby avoiding the need for the staff to support and adjust it during the connection process, thereby improving the efficiency of connecting the ductile iron pipe.

[0038] When it is necessary to adjust the position of the movable plate 608, the limiting screw rod 78 is rotated to make it rotate on the inner wall of the second limiting plate 77, so that the limiting screw rod 78 is away from the first limiting plate 76, the restriction on the position of the movable top plate 74 is released, and the first limiting plate 76 is pulled so that the movable top plate 74 drives the second sliding block 75 to slide on the surface of the second slide groove on the return frame 71. At this time, the movable top plate 74 moves away from the fixed top plate 72. After the movement of the movable plate 608 is completed, the fixed top plate 72 is moved closer to the fixed top plate 72 and the shielding plate 73, and the fixed top plate 72 and the movable top plate 74 are connected by the limiting screw rod 78 to cover the groove on the bottom plate. By setting the covering device 7, the groove on the base 1 for the movable plate 608 to move can be covered during the process of connecting the ductile iron pipe using the movable chain device for quick installation of the ductile iron pipe, thereby preventing impurities from entering the groove on the base 1 and affecting the movement of the movable plate 608.
