Embodiment 2

[0061] Embodiment 2, its difference with embodiment 1 is, as Figure 15 and Figure 16 As shown, the K-shaped sleeve 3-2 is provided with a rotation auxiliary mechanism 16 for connecting the shoulder shaping assembly 2 so that the shoulder shaping assembly 2 can swing left and right; the rotation auxiliary mechanism 16 includes a rotation auxiliary housing 16-1 and the connecting sleeve 16-2 hingedly connected in the rotating auxiliary housing 16-1, the hinge shaft of the connecting sleeve 16-2 is set in the axial direction of the water stop curtain 13; the connecting sleeve 16-2 and the shoulder shaping assembly The sizing rods of 2 are connected so that the shoulder sizing assembly 2 can swing left and right in the plane of the water-stop curtain.

Embodiment 3

[0062] Embodiment 3, its difference with embodiment 1 is, as Figure 13 As shown, the connector 3 includes a Y-shaped sleeve 3-1 and two 1-shaped sleeves 3-4 symmetrically arranged on both sides of the Y-shaped sleeve 3-1, and the 1-shaped sleeve 3-4 and The Y-shaped sleeve 3-1 is connected by the fixing pipe 3-3 to form an isosceles triangle structure; and the shoulder shaping component 2 is omitted. This embodiment 1 is mainly used for water-stop cords with smaller specifications.

Embodiment 4

[0063] Embodiment 4, its difference with embodiment 1 is, as Figure 14 As shown, for heavier or larger water-tight curtains, two symmetrical shoulder shaping components can also be added, and correspondingly, a sleeve can be added to the K-type connecting sleeve 3-2 for passing through the shaping rod 5Connect the shoulder shaping components.

Abstract

The invention provides a hoisting device for full-section water stop curtain cloth. The device comprises a plurality of shaping mechanisms, the plurality of shaping mechanisms are distributed along the annular direction of the water stop curtain cloth, and clamping pieces for clamping the water stop curtain cloth are arranged on the shaping mechanisms; and the connector is used for connecting the plurality of shaping mechanisms together to form a claw-shaped opening frame. According to the invention, at least three supporting points are arranged on the claw-shaped opening frame to fix the water stop curtain cloth for full-section hoisting so that the water stop curtain cloth is prevented from falling off to cause personal injury; and the water stop curtain cloth is completely opened to avoid overturning so that the water stop curtain cloth can be accurately mounted on the portal stud, the mounting process is more convenient, and reworking and influence on the construction period are avoided.

Description

technical field [0001] The invention relates to the field of hoisting water-stop cords, in particular to a hoisting device and a hoisting method for full-section water-stop cords. Background technique [0002] The water-stop curtain works together with embedded studs, ring plates, pressure plates and flaps to effectively prevent the muddy water in the tunnel from seeping into the working well. However, due to its own material characteristics, the shape is not easy to control during lifting, and the full-section lifting cannot be achieved. Moreover, during installation, there are problems such as small operating space for workers, heavy weight and easy folding of the water-stop curtain, and difficulty in aligning the holes. Unfavorable conditions such as difficult installation and operation, high risk, and frequent rework. [0003] There are two ways to install water-stop curtains from the top of the cave door from top to bottom and from the bottom of the cave door to top-up...
