[0038] The lifting mechanism includes: a first hydraulic jack 21 and a second hydraulic jack 22. A support plate 23 is installed at the top end of the first hydraulic jack 21, and a notch 231 is opened at the bottom end of the support plate 23.

[0039] A moving plate 24 is installed at the top of the second hydraulic jack 22. The moving plate 24 is adapted to the notch 231 and contacts the inner wall of the notch 231. The moving plate 24 is provided with at least one groove 241. A pulley 25 is connected inside the groove 241 to rotate along the translation direction of the shield machine.

[0040] In the embodiment of the utility model, the first hydraulic jack 21 is used as the main hydraulic jack, the second hydraulic jack 22 is used as the auxiliary hydraulic jack, the support plate 23 is welded and fixed to the top of the first hydraulic jack 21, and the moving plate 24 is welded and fixed to the top of the second hydraulic jack 22. Two groups of grooves 241 are provided, and the grooves 241 are rectangular in design, which is convenient for the installation of the pulley 25.

[0041] The utility model provides a shield machine vertical lifting device for the horizontal movement of the shield machine through the station. The utility model combines the moving mechanism and the lifting mechanism to realize the function of facilitating the movement of the first hydraulic jack 21 and the second hydraulic jack 22 on the moving structure, reduces the setting of the hydraulic jack, and facilitates the horizontal movement of the shield machine through the station. The support plate 23 fixed on the first hydraulic jack 21 is used to support the bottom end of the shield machine and adjust the height position of the shield machine. When the fixed position of the first hydraulic jack 21 and the second hydraulic jack 22 is to be moved, firstly, a group of the first hydraulic jack 21 is moved downward to drive the support plate 23 to descend. At this time, the support plate 23 and the moving plate 24 will move relative to each other until the pulley 25 rotating on the moving plate 24 contacts the bottom end of the shield machine. At this time, there is no need to set more jacks on the moving path of the shield machine. Only by pushing the first hydraulic jack 21 and the second hydraulic jack 22 to move on the moving mechanism can the stable horizontal movement of the shield machine through the station be realized.

[0042] In some feasible embodiments, limiting grooves 232 are provided on both sides of the inner wall of the notch 231 along the extension and contraction direction of the first hydraulic jack 21 , and positioning blocks 242 are provided on both sides of the movable plate 24 corresponding to the limiting grooves 232 , and the positioning blocks 242 are slidably connected in the limiting grooves 232 .

During operation, through the structural design of the limiting groove 2328 and the positioning block 242, when the second hydraulic jack 22 pushes the movable plate 24 to move upward, the positioning block 2429 fixed on the movable plate 24 will slide in the limiting groove 232, thereby ensuring that the movable plate 24 can only move in the telescopic direction of the hydraulic jack, that is, the vertical direction, through the contact between the positioning block 242 and the inner wall of the limiting groove 232, so that the movable plate 24 can be more stable when moving.

[0044] In some feasible embodiments, stoppers 243 are further provided on both sides of the movable plate 24 , and the shape of the stoppers 243 is adapted to the movable plate 24 .

[0045] During operation, a stopper 243 is fixed on the movable plate 24. The stopper 243 is designed to be arc-shaped as a whole, so as to fit with the bottom end of the support plate 23. When the support plate 23 moves downward until it abuts against the stopper 243, the support plate 23 cannot move downward any further, so as to control the moving distance of the support plate 23.

[0049] The moving parts include: multiple groups of moving wheels 33 and support blocks 34. The moving wheels 33 are arranged at the bottom end of the base 32. The top of the steel plate 31 is provided with a slide groove 312 corresponding to the moving wheels 33 along the translation direction of the shield machine.

[0051] In this embodiment, a through groove 311 is provided on the steel plate 31 to facilitate the normal movement of the support block 34 in the steel plate 31.

[0053] In this embodiment, a slot 341 is provided on the support block 34. When the support block 34 moves in the steel plate 31, the slot 341 will also slide in the block 313, thereby limiting the movement of the support block 34 in the vertical direction. At the same time, through the contact between the block 313 and the slot 341, the supporting strength of the support block 34 on the base 32 can also be improved.

[0054] In some feasible embodiments, a support bar 314 is disposed on the inner wall of the steel plate 31 along the length direction of the steel plate 31 .
