[0041] like Figures 1 to 10 As shown, it includes: a mobile support frame 1, the mobile support frames 1 are arranged in two, and a plurality of universal wheels for movement are installed at the bottom of the two mobile support frames 1;

[0042] A lifting frame is arranged between two mobile support frames 1, and a lifting assembly for lifting is arranged between the mobile support frames 1. A fixed frame 3 is arranged at the bottom of the lifting frame, and a winch 4 is installed on the top of the fixed frame 3. The winch 4 is detachably fixed. The twisted rope of 4 passes through the fixed frame 3, and one end of the twisted rope is fixedly connected to a fixing part 5 for lifting materials;

[0043] Two movable side plates 8, the two movable side plates 8 are respectively arranged on both sides of the interior of the fixed frame 3 and are slidably arranged with the fixed frame 3, the opposite sides of the two movable side plates 8 are connected with a rotating rod 9 through an adjusting member, which is used to adjust the angle of the rotating rod 9, and the opposite ends of the two rotating rods 9 are provided with a clamping member for positioning the material;

[0044] like Figure 3, the traction member includes two first electric telescopic rods 7, both ends of the two first electric telescopic rods 7 are fixedly connected with mounting blocks 6, a steel wire rope 601 is fixedly connected between the mounting block 6 and the movable side plate 8, and a support roller 602 is rotatably connected between the two mounting blocks 6 on the same side.

[0045] During specific implementation, in this embodiment, the prefabricated panels in the building are fixed by the fixing member 5, which can be fixed by bolts or other means, and then the winch 4 is started to reel in the rope, so that the fixing member 5 can be pulled into the fixed frame 3, and then the first electric telescopic rod 7 in the traction member is contracted to make the two mounting blocks 6 approach each other, and a support roller 602 is rotatably connected between the two mounting blocks 6. As the first electric telescopic rod 7 contracts, the support roller 602 is centered below the panel. When the panel is on the upper part of the support roller 602, the wire rope 601 between the mounting block 6 and the movable side plate 8 is tightened, so that the wire rope 601 pulls the two movable side plates 8 automatically to the two sides of the panel, so that the clamping member arranged on one side of the movable side plate 8 clamps the panel, and the clamping effect is achieved by the weight of the panel itself, thereby ensuring the stability of the panel during the lifting process.

[0046] like Figure 4 - Figure 5 As shown, further, the clamping member includes a fixed plate 904 fixedly connected to one end of the rotating rod 9, a contact plate 901 is provided on one side of the fixed plate 904, a third telescopic device 902 and a third spring 903 are fixedly connected between the contact plate 901 and the fixed plate 904, the outer side of the third spring 903 is sleeved on the outer side of the third telescopic device 902, and two transmission racks 905 are fixedly connected to one side of the contact plate 901 close to the fixed plate 904, and the two transmission racks 905 pass through the fixed plate 904 and are slidably connected to the fixed plate 904.

[0047] The clamping member also includes a transmission gear 906 that is respectively meshed with the two transmission racks 905. The tops of the two transmission gears 906 are fixedly connected with a rotating rod 907. The rotating rod 907 passes through the fixed plate 904 and is rotatably connected to the fixed plate 904. The outer sides of the two rotating rods 907 are fixedly connected with a clamping plate 908. The two clamping plates 908 are hinged with a positioning block 909 at one opposite end.

[0048] In specific implementation, when the contact plate 901 on one side of the fixed plate 904 contacts the plate, the contact plate 901 drives the fixedly connected transmission rack 905 to push the meshingly connected transmission gear 906 to rotate. When the transmission gear 906 rotates, it drives the fixedly connected rotating rod 907 to rotate, so that the rotating rod 907 drives the fixedly connected clamping plate 908 to rotate, and then the two clamping plates 908 rotate relative to each other, so that the positioning block 909 hinged at one end of the clamping plate 908 clamps and fixes the plate. When the fixing part 5 is detached, the plate itself can automatically achieve a locking effect to avoid accidents during the lifting process.

[0049] Furthermore, the two movable side plates 8 are fixedly connected with a plurality of first telescopic rods 301 and a first spring 302 on one side close to the fixed frame 3. The plurality of first telescopic rods 301 and the first spring 302 are fixedly connected to the fixed frame 3. A limiting rod 303 is fixedly connected inside the fixed frame 3. The limiting rod 303 passes through the two movable side plates 8 and is slidably connected to the movable side plates 8.

[0050] In a specific implementation, in order to ensure that the two movable side plates 8 can be automatically reset after being clamped, the movable side plates 8 can be pulled to reset through the first telescopic rod 301.

[0051] like Figure 1 - Figure 7 As shown, embodiment 2: the lifting frame includes a lifting plate 2, a rotating frame 201 is arranged at the bottom of the lifting plate 2, the rotating frame 201 is fixedly connected to the top of the fixed frame 3, the rotating frame 201 passes through the lifting plate 2 and is rotatably connected to the lifting plate 2, a second motor 202 is fixedly connected to the top of the lifting plate 2, and the output end of the second motor 202 is fixedly connected to the rotating frame 201.

[0052] The lifting assembly includes a lifting screw rod 101 arranged inside the two mobile support frames 1. The lifting screw rod 101 passes through the top of the mobile support frame 1 and is rotatably connected to the mobile support frame 1. A first motor 102 is fixedly connected to the bottom of the mobile support frame 1, and the output end of the first motor 102 is fixedly connected to the lifting screw rod 101.

[0053] During the specific implementation, by starting the first motor 102 on the mobile support frame 1, the first motor 102 drives the lifting screw 101 to rotate, and the lifting screw 101 drives the lifting plate 2 to rise. When the plate needs to be placed in the specified installation position, the second motor 202 can be started, and the second motor 202 drives the rotating frame 201 to rotate, and then drives the fixed frame 3 to rotate, so that the plate can be adjusted for easy construction and installation.

[0054] As shown in Figure 6, embodiment three: the adjusting member includes a rotating disk 801 fixedly connected to one end of the rotating rod 9, the rotating rod 9 passes through the movable side plate 8 and is rotatably connected to the movable side plate 8, an installation groove 802 is provided on the outer side of the rotating disk 801, a positioning groove is provided on the outer side of the movable side plate 8, a positioning plate 803 is arranged on one side of the rotating disk 801, and the positioning plate 803 is fixedly connected with an insertion rod 804 on one side of the rotating disk 801, the insertion rod 804 is adapted to the positioning groove and the installation groove 802, a pulling frame 805 is fixedly connected to the other side of the positioning plate 803, a fixed frame 807 is fixedly connected to one side of the movable side plate 8, the pulling frame 805 passes through the fixed frame 807 and is slidably connected to the fixed frame 807, and a plurality of second springs 806 are fixedly connected between the positioning plate 803 and the fixed frame 807.

[0055] The specific implementation is that when hoisting the columnar material, the angle of the rotating rod 9 is rotated by the adjusting part so that the contact plate 901 in the clamping part is kept parallel to the state material, and the pulling frame 805 is pulled, and the pulling frame 805 drives the positioning plate 803, so that the insertion rod 804 inserted into the rotating disk 801 and the movable side plate 8 on one side of the positioning plate 803 is moved out, and then the rotating disk 801 is rotated to make the rotating disk 801 drive the rotating rod 9 to rotate, so that the rotating rod 9 drives the entire clamping part to rotate, and when the columnar material is fixed by the fixing part 5, it is placed on the upper part of the two first electric telescopic rods 7, and the supporting roller 602 contacts the columnar material. After the movable side plate 8 moves, the contact plate 901 contacts the surface of the columnar material, and the contact plate 901 is pushed, so that the clamping plate 908 clamps the columnar material, thereby achieving auxiliary fixation of the cylindrical material.

When the electromagnet 11 is energized, it is magnetically attracted to the metal block 12.

[0057] In specific implementation, when the material is lifted to the inside of the fixed frame 3, due to the different weights of different materials, the force with which the material presses down on the mounting block 6 is also different. By arranging a second electric telescopic rod 10 on the upper part of the fixing member 5, the second electric telescopic rod 10 squeezes the fixing member 5, thereby ensuring the force of the material pressing down. In order to prevent the material from shaking during the clamping process after being lifted into the inside of the fixed frame 3, the electromagnet 11 can be energized. After the electromagnet 11 is energized, it has magnetism, thereby adsorbing the metal block 12 on the second electric telescopic rod 10 to ensure the stability of the fixing member 5.

[0058] It is worth noting that in the present application, by installing an operation terminal on one of the mobile support frames 1 and setting a controller, electrical control is performed on the first motor 102, the second motor 202, the first electric telescopic rod 7 and other electrical components respectively.

[0059] The embodiment of the present application also provides: a lifting method based on the construction of an assembled building, comprising the following steps:

[0060] S1, fix the fixing member 5 to the outside of the material and lift it to the inside of the fixing frame 3;

[0061] S2, by starting the first electric telescopic rod 7, the first electric telescopic rod 7 pulls the mounting blocks 6 at both ends to move closer, so that the mounting blocks 6 move to the lower part of the material. When the material presses down the support roller 602, the steel wire rope 601 pulls the movable side plate 8 closer;

[0062] S3, when the side plate 8 is moved close to the material, the two sides of the material are clamped and fixed by the clamping parts;

[0063] S4. Finally, the lifting assembly is started to drive the entire fixed frame 3 and the clamped material to rise and move to a specified position.
