[0020] The following is combined with Figure 1-2 This application is described in further detail.

[0021] The present application embodiment discloses a prefabricated shear wall elevation adjustment jacking device, such as Figure 1 As shown, it includes a basic frame 1, a lifting rod 2 and a lifting support assembly 3. The lifting rod 2 is movably connected to the basic frame 1, and the lifting support assembly 3 is used to enable the lifting rod 2 to move vertically relative to the basic frame 1.

[0022] like Figure 1 As shown, the basic frame 1 is placed on the ground, and includes a central rod 11 and two wing rods 12. The two wing rods 12 are distributed on opposite sides of the central rod 11, and the ends of the two wing rods 12 are hinged to the same end of the central rod 11. The axial direction of the hinge axis is vertical, that is, the two wing rods 12 can be simultaneously unfolded relative to the central rod 11, and the length directions of the three are coplanar. One end of the jacking rod 2 is hinged to the basic frame 1, and the jacking rod 2 and the wing rod 12 are hinged to the same end of the central rod 11. The hinge axis of the jacking rod 2 is in the horizontal direction, and the jacking support assembly 3 is used to control the rotation of the jacking rod 2 relative to the basic frame 1.

[0023] like Figure 1 and 2 As shown, the supporting assembly 3 includes a supporting motor 31, a supporting screw rod 32, a supporting slider 33 and a supporting rod 34. The supporting screw rod 32 is rotatably connected to the lifting rod 2 and the length directions of the two are consistent. The supporting motor 31 is fixed on the lifting rod 2. The output shaft of the supporting motor 31 is coaxially connected to the supporting screw rod 32, which is used to control the rotation of the supporting screw rod 32. The supporting slider 33 is slidably connected to the lifting rod 2, and the sliding direction is consistent with the length direction of the lifting rod 2. The supporting slider 33 is threadedly connected to the supporting screw rod 32. One end of the supporting rod 34 is hinged to the base frame 1, and the other end is hinged to the supporting slider 33. The axis of its hinge shaft is parallel to the hinge axis of the lifting rod 2. When the supporting screw rod 32 rotates, the supporting slider 33 carries the end of the supporting rod 34 to move relative to the supporting rod, so that the supporting rod 34 lifts the lifting rod 2, and the lifting rod 2 can rotate relative to the center rod 11. An accommodating groove 111 is provided above the center rod 11 . When the lifting rod 2 rotates until its length direction is consistent with that of the center rod 11 , the lifting rod 2 , the supporting screw rod 32 and the supporting rod 34 are all completely located in the accommodating groove 111 .

[0024] like Figure 1 and 2As shown, a folding rod 4 is provided between the side wing rod 12 and the lifting rod 2. One end of the folding rod 4 is freely hinged to the side wing rod 12, and the other end is freely hinged to the lifting rod 2. The free hinge can be in the form of a ball joint or a universal joint. In this embodiment, a universal joint is used. The folding rod 4 includes two connecting rods 41. The ends of the two connecting rods 41 are hinged. The axial direction of the hinge shaft is perpendicular to the length direction of the connecting rod 41. The hinge point of the two connecting rods 41 is the center point of the folding rod 4.

[0025] like Figure 1 and 2 As shown, when the wing rods 12 are close to the center rod 11 and the lifting rod 2 is close to the center rod 11, the wing rods 12 and the lifting rod 2 are also close to each other, and the folding rod 4 is in a folded state. When the wing rods 12 are unfolded relative to the center rod 11, the lifting rod 2 rotates upward relative to the center rod 11, and the wing rods 12 and the lifting rod 2 are also relatively far away, the folding rod 4 is dynamically unfolded, and when the length directions of the two hinged connecting rods 41 are consistent, the lifting rod 2 cannot continue to rotate upward when the angle of the wing rods 12 relative to the center rod 11 remains unchanged.

[0026] like Figure 2 As shown, the end of the center rod 11 is fixedly connected with a matching wedge 112, and the wedge surface of the matching wedge 112 is located on the side away from the center rod 11 and tilted upward. When the jacking rod 2 is located in the receiving groove 111, the matching wedge surface is conducive to the end of the center rod 11 carrying the jacking rod 2 to be smoothly inserted under the prefabricated shear wall. The end of the jacking rod 2 away from its own hinge point is detachably provided with a consumption block 21 through a bolt, and the consumption block 21 is used to abut against the prefabricated shear wall.

[0027] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
