[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0025] Example:

[0026] like Figure 1-Figure 7 As shown, the utility model provides a universal movable wet joint tooling, including a lifting assembly and a base plate assembly. The base plate assembly includes a base plate 1. The width of the base plate 1 is matched with the gap between two adjacent box beams 2, so that the base plate 1 can cover the gap from below, thereby blocking the gap between the box beams 2 to form a groove shape. The lifting assembly includes a lifting device and a lifting rope 3. The lifting device can be an electric hoist or other lifting mechanism. The lifting device is arranged on the upper surface of the box beam 2. The two ends of the lifting rope 3 are respectively connected to the base plate 1 and the lifting device, so that the lifting device can lift the base plate 1 to the lower surface of the box beam 2 through the lifting rope 3.

[0027] When the universal movable wet joint tooling of the utility model is used, the lifting device is placed above the box beam 2. The lifting rope 3 is lowered through the gap between two adjacent box beams 2, and then connected to the bottom plate 1 and the bottom plate 1 is lifted to fit the lower surface of the box beam 2. In this way, the bottom of the gap between the box beams 2 is blocked by the bottom plate 1, and then concrete can be poured into the gap.

[0028] The gap bottom can be quickly sealed by hoisting, which improves construction efficiency. At the same time, this operation does not require workers to install bottom membrane from the bottom of the bridge to seal the gap between the box beams 2. There is no need for high-altitude work, which is safer.

[0029] In this embodiment, the lifting device includes a gantry 4 and a winch 5. The winch 5 is installed on the gantry 4. One end of the lifting rope 3 is connected to the winch 5. The winch 5 can be rotated to retract the lifting rope 3, thereby lifting or lowering the bottom plate 1. A roller 6 is provided at the bottom of the gantry 4. After the bottom plate 1 is hoisted in place and fixed, the bottom plate 1 can be separated from the lifting rope 3, so that the gantry 4 can be moved to the next station to hoist the bottom plate 1. The provision of the roller 6 makes the movement of the gantry 4 more convenient.

[0030] In this embodiment, two groups of door frames 4 are provided, and the two groups of door frames 4 are arranged at intervals. Each group of door frames 4 is provided with two winches 5. The bottom plate 1 is provided with a sling 7 in cooperation with each sling rope 3, so that each sling rope 3 is connected to a sling 7. The specific diagram of the cooperation between the door frame 4 and the bottom plate 1 is shown in FIG. Figure 1 As shown. This allows the base plate 1 to be hoisted by four hoisting ropes 3 at the same time. At the same time, the four hoisting ropes 3 are distributed in a rectangular shape, making the base plate 1 more stable during the hoisting process.

[0031] In this embodiment, the sling 7 and the sling rope 3 are provided with a connecting buckle 15. The connecting buckle 15 includes a male head 8 and a female head 9 respectively connected to the sling 7 and the sling rope 3. The male head 8 is in a truncated cone shape and the sling 7 is connected to the small diameter end of the male head 8. The female head 9 is in a disc shape. The female head 9 is provided with a notch for the sling 7 to pass through. The width of the notch is the same as the diameter of the sling 7. The female head 9 is provided with a funnel shape at the end of the notch to cooperate with the male head 8, so that the outer wall of the male head 8 fits the inner wall of the female head 9.

[0032] After the sling 7 is inserted through the gap, the sling rope 3 and the sling 7 are tightened, so that the male head 8 is sunk into the funnel-shaped part of the female head 9. Since the male head 8 is larger than the diameter of the sling 7, the male head 8 cannot pass through the gap. This enables the base plate 1 to be lifted by the sling 7 when the sling 3 is lifted. In addition, since the width of the gap is equivalent to the diameter of the sling 7, and the diameter of the funnel-shaped part of the female head 9 is much larger than the diameter of the sling 7. In other words, the width of the gap does not reach the diameter width of the funnel-shaped part of the female head 9. After the male head 8 is inserted into the funnel-shaped part of the female head 9, it cannot slide out through the gap. As a result, the male head 8 and the female head 9 will not separate during the lifting process, thereby ensuring the safety of the lifting process.

[0033] When in use, the lifting rope 3 passes through the gap between the box beams 2 to the ground under the bridge. The lifting rope 7 is manually placed in the gap and the lifting rope 3 is pulled upward to effectively connect the male head 8 and the female head 9. Then the bottom plate 1 can be lifted for hoisting. After the bottom plate 1 is hoisted in place and fixed, the male head 8 is first pushed to separate it from the female head 9, and then the lifting rope 3 can be taken out from the gap to completely separate the lifting rope 3 and the lifting rope 7.

[0034] In order to reuse the bottom plate 1, a PVC pipe 14 is put on the outside of the sling 7 before the bottom plate 1 is hoisted. After the bottom plate 1 is hoisted in place, the PVC pipe 14 is located in the gap between the box beams 2. When pouring concrete into the gap, the concrete and the sling 7 are separated by the PVC pipe 14. After the wet joint is completed, the male head 8 and the female head 9 are connected, so that the sling rope 3 and the sling 7 are lowered through the inside of the PVC pipe 14, and the bottom plate 1 is lowered to the ground under the bridge and can be reused. Such male head 8 and female head 9 are both set to be small, so that they can pass through the PVC pipe 14 conveniently.

[0035] In order to facilitate the movement of the bottom plate 1 to the next station for reuse, rollers 6 are further provided at the lower part of the bottom plate 1 to facilitate the movement of the bottom plate 1.

[0036] In this embodiment, a positioning rod 10 is further included. The positioning rod 10 is arranged in cooperation with the sling 7 so that the sling 7 can be connected to the positioning rod 10, thereby lifting the bottom plate 1. When the bottom plate 1 is hoisted in place, the sling 7 is connected to the positioning rod 10 to separate the sling rope 3 and the sling 7. After the two are separated, the bottom plate 1 is lifted by the positioning rod 10, thereby enabling the gantry 4 to be moved to the next station for continued use.

[0037] In this embodiment, the positioning rod 10 is provided with a notch for the sling 7 to pass through. The sling 7 can be conveniently inserted into the notch from the side. The positioning rod 10 is provided with a boss 11 protruding from the notch. The outer wall of the boss 11 is provided with a thread. The sling 7 is sleeved with a slidable nut 12. The nut 12 is provided in cooperation with the thread. Figure 7 As shown, clips 13 are provided on opposite sides of the upper surface of the boss 11. The inner wall of the nut 12 and the clips 13 cooperate with each other to form an inclined surface, so that when the nut 12 is tightened, the nut 12 gradually presses the clips 13 against the sling 7.

[0038] After the base plate 1 is hoisted in place, the positioning rod 10 is moved from the side, so that the sling 7 enters the inside of the notch. Then, the nut 12 is tightened on the thread of the boss 11. During the tightening process of the nut 12, its inner wall continuously squeezes the two clamps 13, so that the clamps 13 contact and clamp the sling 7. This makes the sling 7 stably connected to the positioning rod 10. At this time, the sling 3 and the sling 7 can be separated. Similarly, before removing the base plate 1, the sling 7 and the sling 3 are connected first. Then the nut 12 is unscrewed, so that the sling 7 and the positioning rod 10 are separated.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
