The hanger is lifted by the lifting device, and the connecting plate 12 is connected to the main shaft assembly through the connecting component to ensure that the main shaft assembly is horizontal. The connecting frame 13 is located between the top frame 11 and the connecting plate 12. There is no vertical structure on one side of the connecting frame 13, so that the connecting frame 13 avoids the top beam of the portal column and avoids interference between the hanger and the portal column, thus overcoming the problem of interference between the hanger and the portal column when the main shaft assembly is lifted.

Preferably, one end of the top frame 11 is fixedly connected to the connecting frame 13, and the other end extends away from the connecting frame 13 to form a free end; one end of the connecting plate 12 is fixedly connected to the connecting frame 13, and the other end extends in the extension direction of the top frame 11 to form a free end. The extension length of the free end of the top frame 11 is greater than the extension length of the free end of the connecting plate 12, so that when the lifting device lifts the hanger, the connecting plate 12 is located outside the portal column, and the top frame 11 can be moved to the top of the portal column. When the structure inside the portal column is compact and the space is small, this structural form can prevent the hanger from entering the portal column and causing interference; and this structural form is also convenient for adjusting the center of gravity of the structure to make the main shaft assembly more stable during lifting.

Specifically, the top frame 11 is a rectangular frame structure formed by splicing and welding steel. The connecting rod 111 is made of I-beam, and the two ends of the connecting rod 111 are respectively welded to the two short frames of the top frame 11. The connecting frame 13 includes a first rod parallel to a short frame of the top frame 11, and three parallel and spaced second rods are arranged between the first rod and the corresponding short frame of the top frame 11, wherein two second rods are located at the two ends of the first rod and correspond to the two ends of the short frame of the top frame 11, and the two ends of the remaining second rod are respectively located at the middle of the first rod and the short frame of the top frame 11; a third rod parallel to the long frame of the top frame 11 is respectively arranged at the two ends of the first rod, and the first rod, the second rod, the third rod and the top frame 11 are all welded and fixed. A first oblique support is added to the corner formed by the second rod and the long frame of the top frame 11 for reinforcement, and a second oblique support is added to the corner formed by the second rod and the third rod for reinforcement. The connecting plate 12 is composed of two pieces and is respectively welded and fixed to the bottom of the two third rods. The entire hanger structure adopts a frame structure, which reduces the weight of the hanger while ensuring the structural strength, making it easier to lift and adjust the hanger.

The connecting bolts are connected to the main shaft assembly after passing through the elongated holes 121. The main shaft assembly is provided with mounting threaded holes that cooperate with the connecting bolts. The connecting bolts are screwed into the mounting threaded holes after passing through the elongated holes 121 to connect the main shaft assembly to the hanger. The elongated holes 121 are used to adjust the position of the main shaft assembly to prevent the main shaft assembly from being offset and causing unstable hoisting.

Preferably, the lifting device further comprises a mounting frame 22, and the first lifting claw assembly comprises a pair of bent first lifting claws 23, the bending part of the first lifting claws 23 is rotatably connected to the mounting frame 22; one end of the first lifting claw 23 is hook-shaped, and the other end is connected to the lifting frame 21 through a chain 24; along the direction in which the two connecting rods 111 are separated, the hook-shaped openings of the two first lifting claws 23 are arranged opposite to each other, the size of the mounting frame 22 is larger than the distance between the two connecting rods 111, and the distance between the rotation axes of the two first lifting claws 23 is smaller than the distance between the two connecting rods 111. The lifting frame 21 drives the mounting frame 22 to fall, and the hook-shaped ends of the two first lifting claws 23 can extend between the two connecting rods 111, and the mounting frame 22 can be placed on the two connecting rods 111. The lifting frame 21 continues to fall, and the two first lifting claws 23 rotate around their respective rotation axes under the action of gravity, and the hook-shaped ends of the two first lifting claws 23 approach each other, and the two first lifting claws 23 are separated from the two connecting rods 111. The lifting frame 21 is lifted, and the lifting frame 21 lifts the two first hanging claws 23 through the chain 24 to rotate the two first hanging claws 23 around their respective rotation axes, and the hooked ends of the two first hanging claws 23 move away from each other to hook up the two connecting rods 111, thereby lifting the hanger.

Specifically, the mounting frame 22 includes two fourth rods arranged in parallel with the two connecting rods 111, and the two ends of the two fourth rods are welded with fifth rods, the fifth rod is perpendicular to the fourth rod and the length is greater than the distance between the two connecting rods 111, so that the two ends of the fifth rod can be placed on the two connecting rods 111. The ends of the fifth rod are provided with vertically penetrating rectangular holes, the first hanging claws 23 pass through the rectangular holes and the bending part of the first hanging claws 23 is located in the rectangular holes, and the bending part of the first hanging claws 23 is hinged with the fifth rod to realize rotational connection. There is a gap between the rectangular hole and the end of the fifth rod to increase the rotation angle of the first hanging claws 23, which is conducive to the two first hanging claws 23 to escape from between the two connecting rods 111.

Preferably, a vertical guide rod 221 is fixedly provided on the mounting frame 22 by welding, and a sleeve 211 is fixedly provided on the lifting frame 21, and the sleeve 211 is sleeved on the guide rod 221 and slides along the guide rod 221; a plurality of second hanging claws 222 are evenly distributed around the sleeve 211, and one end of the second hanging claw 222 is hook-shaped and the other end is rotatably connected to the sleeve 211. A guide block 223 is fixedly provided on the outer wall of the guide rod 221, and the number of the guide blocks 223 is consistent with the number of the second hanging claws 222 and corresponds one to one; a sliding block 224 is provided between the guide block 223 and the mounting frame 22, and the sliding block 224 is sleeved and slides along the guide rod 221.

The guide block 223 is provided with a first inclined surface, which is inclined from the guide block 223 toward one end of the sliding block 224 along the center line direction of the guide rod 221 to the outer wall of the guide rod 221; the sliding block 224 is provided with a second inclined surface, which is inclined from the sliding block 224 toward one end of the guide block 223 along the center line direction of the guide rod 221 to the outer wall of the guide rod 221; the maximum value of the distance between the first inclined surface and the center line of the guide rod 221 is less than or equal to the maximum value of the distance between the second inclined surface and the center line of the guide rod 221;

A third inclined plane is provided at one end of the second hanging claw 222 away from the sleeve 211. The inclination direction of the third inclined plane is consistent with that of the first inclined plane. The third inclined plane can slide along the first inclined plane. The maximum value of the distance between the third inclined plane and the center line of the guide rod 221 is greater than or equal to the maximum value of the distance between the second inclined plane and the center line of the guide rod 221.

When the lifting frame 21 falls, the third inclined surface on the second lifting claw 222 slides along the first inclined surface, and the guide block 223 pushes the second lifting claw 222 to rotate outward around its rotation axis. When the hook-shaped opening of the second lifting claw 222 passes over the first inclined surface, the hook-shaped opening of the second lifting claw 222 can hook the end surface of the guide block 223 facing the sliding block 224, and then multiple second lifting claws 222 can lift the guide rod 221 through the guide block 223, completing the lifting of the entire lifting device, making it easy to adjust the grabbing position of the first lifting claw 23 according to the center of gravity.

When the lifting frame 21 continues to fall, the edge of the end of the sliding block 224 away from the mounting frame 22 abuts against the third inclined surface, and the third inclined surface and the sliding block 224 can slide relative to each other, so that the second lifting claw 222 rotates outward around its rotation axis, and the hook-shaped opening of the second lifting claw 222 disengages from the end surface of the sliding block 224 and abuts against the second inclined surface. At this time, the lifting frame 21 is lifted, and the second lifting claw 222 hooks the sliding block 224 and moves upward. After the sliding block 224 abuts against the guide block 223, the second lifting claw 222 continues to move upward and disengages from the second inclined surface and rotates under the action of gravity to abut against the first inclined surface, thereby realizing that the second lifting claw 222 automatically disengages from the guide block 223, and the second lifting claw 222 can no longer lift the guide rod 221, and the sleeve 211 can slide upward along the guide rod 221. After the lifting frame 21 is continuously lifted, the hook-shaped ends of the two first lifting claws 23 move away from each other and hook the two connecting rods 111 to lift the hanging frame.

Preferably, a counterweight block 225 is provided on the second hanging claw 222 , and the counterweight block 225 and the gravity exerted on the second hanging claw 222 drive the second hanging claw 222 to rotate.
