It is used to lift raw materials for construction, such as steel bars, wooden planks, concrete, steel pipes, etc. Prefabricated buildings refer to buildings assembled on site from prefabricated parts and components. When constructing prefabricated buildings, it is usually necessary to use a lifting device to lift the prefabricated panels.

[0003] The current prefabricated building lifting device, as described in the patent with announcement number CN219279261U, includes a base, a hanger is fixedly installed on the top of the base, a rope winding mechanism is installed on the top of the hanger, a lifting rope is wound on the rope winding mechanism, a lifting plate is fixedly connected to the lower end of the lifting rope, a first motor is fixedly installed on the bottom of the lifting plate, a bidirectional screw is fixedly connected to the output end of the first motor, two clamps are threadedly connected to the bidirectional screw, a stud is threadedly connected to the bottom of the clamp, and a pressure plate is rotatably connected to the upper end of the stud.

[0004] With regard to the above-mentioned related technologies, the inventors believe that the prefabricated panels to be lifted can be fixed by clamping them with pressure plates on both sides. During the clamping process of the prefabricated panels, the studs on both sides need to be screwed separately to adjust the positions of the pressure plates on both sides, which makes the fixation of the entire prefabricated panels inconvenient.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] The cam is connected with the lifting of the lifting gear by the spring, and the cam has the advantages that the lifting power is high, the lifting power is low, and the support line is close to the support line of the lifting gear.

[0008] As a further solution of the utility model: guide rods are symmetrically fixedly connected inside the hanger, and the guide rods are slidably connected to the traction blocks on both sides.

[0009] As a further solution of the utility model: the connecting mechanism includes a C-shaped hook fixedly connected to one end of the reining rope away from the reel, a hook rod is sleeved inside the C-shaped hook, and the hook rod is fixedly connected to the traction block on the other side.

[0011] As a further solution of the utility model: the opposite sides of the columns on both sides are fixedly connected with extension plates, and the interior of each group of the extension plates is penetrated by an insert cone.

[0012] As a further solution of the utility model: a right-angle plate is symmetrically fixedly connected to the top of the extension plate, and the right-angle plate is fixedly connected to the column.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] After the utility model adopts the above structure, through the mutual cooperation of the connecting mechanism, the binding rope, the reel, the worm, the bidirectional screw and the traction block, the bidirectional screw can be rotated after the binding rope passes through the prefabricated board to be lifted, so that the bidirectional screw can drive the traction blocks on both sides to move relative to each other during rotation, thereby driving the two sides of the binding rope to move relative to each other, so that the binding rope drives the prefabricated board to move upward until the prefabricated board is tightly against the rubber pad, thereby realizing the fixation of the prefabricated board, simplifying the operation steps for fixing the prefabricated board, and making the fixation of the entire prefabricated board more convenient and quick.

DETAILED DESCRIPTION

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] See also Figure 1-3 An assembled building lifting device includes a top plate 1, the four corners of the bottom of the top plate 1 are fixedly connected to columns 2, the opposite sides of the columns 2 on both sides are fixedly connected to extension plates 16, the top of the extension plates 16 are symmetrically fixedly connected to right-angle plates 18, the right-angle plates 18 are fixedly connected to the columns 2, and the right-angle plates 18 can further connect and fix the columns 2 and the extension plates 16, thereby improving the connection stability between the extension plates 16 and the columns 2. Each group of extension plates 16 is penetrated by an insert cone 17, which can be inserted into the ground, so as to limit the entire device.

[0022] A winch 3 is fixedly connected to the top of the top plate 1, a lifting rope 4 is fixedly connected to the output end of the winch 3, and a hanger 5 is fixedly connected to the end of the lifting rope 4 away from the winch 3. When the winch 3 is started, the lifting rope 4 can be reeled in, thereby driving the hanger 5 to move upward. The hanger 5 is internally rotatably connected to a bidirectional screw 6, and the two sides of the bidirectional screw 6 have opposite thread directions. The outer side of the bidirectional screw 6 is symmetrically threaded with a traction block 10. Both groups of traction blocks 10 are slidably connected to the hanger 5. When the bidirectional screw 6 rotates, it can drive the traction blocks 10 on both sides to move relative to or away from each other. The hanger 5 is internally symmetrically fixedly connected to a guide rod 9, and the guide rod 9 is slidably connected to the traction blocks 10 on both sides. The guide rod 9 can guide the movement of the traction blocks 10.

[0023] The inner part of the traction block 10 is rotatably connected to a reel 13, and the outer side of the reel 13 is symmetrically fixedly connected to a reining rope 12. The reel 13 can reel the reining rope 12 when rotating. A worm wheel 14 is fixedly connected to one end of the reel 13, and a worm 15 is meshedly connected to the top of the worm wheel 14. The worm 15 is rotatably connected to one side of the traction block 10. When the worm 15 rotates, it can drive the worm wheel 14 and the reel 13 to rotate. At the same time, the self-locking property of the worm wheel 14 and the worm 15 can limit the probability of the reel 13 rotating on its own. A connecting mechanism 11 is connected between the reinforcing rope 12 and the traction block 10 on the other side. The connecting mechanism 11 includes a C-shaped hook 111 fixedly connected to one end of the reinforcing rope 12 away from the reel 13. A hook rod 114 is sleeved inside the C-shaped hook 111. The hook rod 114 is fixedly connected to the traction block 10 on the other side. The hook rod 114 is used for the C-shaped hook 111 to hook, thereby limiting the end of the reinforcing rope 12 away from the reel 13.

[0024] One end of the C-shaped hook 111 is rotatably connected to an internal threaded tube 112, and the top of the internal threaded tube 112 is threadedly connected to a limiting screw 113, and the top of the limiting screw 113 is threadedly connected to the other end of the C-shaped hook 111. After the limiting screw 113 is screwed into the inside of the C-shaped hook 111, the probability of the C-shaped hook 111 being separated from the hook rod 114 can be reduced. A limiting block 7 is fixedly connected to the middle position of the bottom of the hanger 5, and the limiting block 7 can play a role in limiting the prefabricated panel to be suspended. The end of the limiting block 7 away from the hanger 5 is fixedly connected to a rubber pad 8, and the rubber pad 8 is used to isolate the limiting block 7 from the prefabricated panel to reduce the probability of the rubber pad 8 causing wear to the prefabricated panel.

[0025] When in use, the two groups of ropes 12 are passed around the bottom of the prefabricated board to be lifted, and then the two groups of C-shaped hooks 111 are hooked on the outer side of the hook rod 114, and then the limiting screw 113 is rotated so that the limiting screw 113 is screwed into the inside of the C-shaped hook 111, and then the worm 15 is rotated so that the worm 15 can drive the worm wheel 14 and the reel 13 to rotate when rotating, and the reel 13 can reel in the rope 12 when rotating, thereby tightening the rope 12, and then the bidirectional screw 6 is rotated so that the bidirectional screw 6 can drive the traction blocks 10 on both sides to move relative to each other when rotating, and the two groups of traction blocks 10 can drive the two ends of the rope 12 to move relative to each other when moving relative to each other, thereby driving the prefabricated board to move upward until the prefabricated board moves upward to be tightly against the rubber pad 8, thereby realizing the tightening and limiting of the prefabricated board, and then the winch 3 can be started, so that the winch 3 can reel in the lifting rope 4 when starting work, thereby realizing the lifting of the prefabricated board.
