[0028] like Figure 1-8 The sealing beam lifting mechanism shown in the figure comprises a horizontally arranged base plate 1, on which two groups of follower hydraulic cylinders 2 are rotatably connected, each group comprising a number of follower hydraulic cylinder 2 components, each follower hydraulic cylinder 2 comprising a sub-cylinder barrel 202 and a sub-telescopic rod 203, that is, a cylinder barrel and a hydraulic rod of a hydraulic cylinder, the sub-cylinder barrel 202 and the sub-telescopic rod 203 are plugged together, and can generate a large supporting force outward, the rotation axes of the two groups of follower hydraulic cylinders 2 are parallel, and the plane where the axes are located is usually parallel to the upper surface of the base plate 1, the lower end of the sub-cylinder barrel 202 is rotatably connected to the base plate 1 through a lower linkage shaft 201, and the follower hydraulic cylinder 2 in this embodiment There are two groups, and there are two corresponding lower linkage shafts 201. The lower ends of the auxiliary cylinders 202 in the same group are only commonly connected to one lower linkage shaft 201, and the other group of auxiliary cylinders 202 are commonly connected to another lower linkage shaft 201. The upper surface of the base plate 1 is fixedly connected with a coupling frame 101, and at least two lower shaft holes 102 are opened on the coupling frame 101. In this embodiment, two of them are opened, which are used to cooperate with the two lower linkage shafts 201 to form a rotating pair, so as to limit the position of the lower linkage shaft 201 relative to the base plate 1. The axis of the lower linkage shaft 201 is parallel to the axis of the upper linkage shaft 204, and the limiting directions of the two are consistent.

[0029] The upper ends of the two groups of follower hydraulic cylinders 2 are movably connected to the same lifting platform 4. The follower hydraulic cylinders 2 are used to adjust the height of the lifting platform 4. In order to keep the lifting platform 4 in a horizontal state during the lifting process, the upper end of the secondary telescopic rod 203 is rotatably connected to the lifting platform 4 through the upper linkage shaft 204, and there are also two upper linkage shafts 204, which can form a parallelogram with the two lower linkage shafts 201, so that the lifting platform 4 can maintain a parallel state with the base plate 1 when changing its position. The lifting platform 4 is used to support the sealing beam to realize lifting and transportation. The specific structure of the lifting platform 4 includes a bottom plate 401, and the lower surface of the bottom plate 401 is fixedly connected to a coupling sleeve 403, and the coupling sleeve 403 is provided with at least two upper shaft holes 404, and the axes of the upper shaft holes 404 are parallel and parallel to the axis of the upper linkage shaft 204, so that the upper linkage shaft 204 passes through to form a rotating pair.

[0030] A baffle 405 is fixedly connected to the side of the bottom plate 401 to limit the sealing beam from sliding out from this side. The baffle 405 is parallel to the upper linkage shaft 204, that is, the length direction of the baffle 405 and the two planes with larger areas are parallel to the axis of the upper linkage shaft 204. A pair of side plates 402 are fixedly connected to the upper surface of the bottom plate 401, and the side plates 402 are perpendicular to the bottom plate 401 and the baffle 405 at the same time. A number of rollers 406 are movably connected between the two side plates 402. The axes of the rollers 406 are on the same horizontal plane and are arranged equidistantly. The highest points of the sides of the rollers 406 are higher than the upper surfaces of the side plates 402 for direct contact with the sealing beam. Both ends of each roller 406 have coaxial end shafts, which are just plugged in with the side plates 402 at both ends to form a rotating pair. The end faces of the two side plates 402 are fixedly connected to the baffle 405, so that the entire lifting platform 4 has good stability.

[0031] An active hydraulic cylinder 3 is movably connected between the follower hydraulic cylinder 2 and the base plate 1, and is used to adjust the inclination angle of the follower hydraulic cylinder 2 relative to the base plate 1. A group of auxiliary cylinders 202 close to the active hydraulic cylinder 3 are fixedly connected to a bridge plate 205 on the same side, so that the same group of follower hydraulic cylinders 2 close to the active hydraulic cylinder 3 remain in the same plane. The active hydraulic cylinder 3 includes a main cylinder 301 and a main telescopic rod 302 that are plug-in matched. The lower end of the main cylinder 301 is rotatably connected to the base plate 1 through a hinge structure 5, and the upper end of the main telescopic rod 302 is rotatably connected to the bridge plate 205 through a hinge structure 5. The axis of the hinge structure 5 is parallel to the axis of the lower linkage shaft 201. After the linkage structure is formed, the freedom of movement is guaranteed.

[0032] Working principle: In the initial state, the active hydraulic cylinder 3 is in a retracted state, the follower hydraulic cylinder 2 is very close to the upper surface of the substrate 1, and the follower hydraulic cylinder 2 is also in a retracted state. The height of the lifting platform 4 is very low, and the upper surface of the lifting platform 4 is horizontal. The worker can put the sealing beam to be used on the roller 406 on the lifting platform 4. Since the lengths of the two sets of follower hydraulic cylinders 2 can be different, fine-tuning can be performed to make the lifting platform 4 slightly tilted so that the sealing beam is against the baffle 405. In this way, when the lifting platform 4 rises, the sealing beam on it is It will be more stable, and then the active hydraulic cylinder 3 can be started to gradually lift the two groups of follower hydraulic cylinders 2. During this process, the lifting platform 4 always maintains its own angle. When the follower hydraulic cylinder 2 is close to the vertical direction, the follower hydraulic cylinder 2 is extended to send the sealing beam placed on the lifting platform 4 to a suitable height. Finally, the length of the two groups of follower hydraulic cylinders 2 is fine-tuned again to change the angle of the lifting platform 4, so that the sealing beam can roll along the roller shaft 406 to the installation position. After that, the lifting mechanism can move in the opposite direction to the initial position and wait for the next round of installation work.
