The two arc tubes 111 are connected by multiple hinges. The rotation axis of the arc tube 111 is parallel to the length direction of the arc tube 111. A plurality of fixed blocks 2 are slidably arranged on the inner wall of the arc tube 111. The fixed blocks 2 are arrayed on the inner wall of the arc tube 111. The sliding direction of the fixed blocks 2 is perpendicular to the axial direction of the arc tube 111. A first driving member for driving the fixed blocks 2 to slide is arranged in the arc tube 111; the lifting device also includes a locking member 3, which is used to drive the two arc tubes 111 to rotate in a direction close to each other to engage the steel component when the lifting tube 1 is lifted.
[0021] When lifting the steel component, first rotate the two arc tubes 111, the two arc tubes 111 rotate relative to each other to open the lifting tube 1, and then lower the lifting tube 1 to make the steel component relatively move into the lifting tube 1, and then lift the lifting tube 1. At this time, under the action of the locking piece 3, the two arc tubes 111 have a tendency to move towards each other and are buckled together to move the steel component into the lifting tube 1. After the steel component is moved into the lifting tube 1, the steel component contacts the fixed block 2 and presses the fixed block 2, so that a groove similar to the contact surface of the steel component is formed on the fixed block 2 arranged in an array. Under the action of the groove, the steel component is fixed in the lifting tube 1, which reduces the possibility of the steel component slipping out of the lifting tube 1 and improves the safety of the steel component lifting.
[0022] Reference Figure 3 In the embodiment of the present application, a mounting cavity 4 is provided in the arc-shaped cylinder 111, and the mounting cavity 4 has the same curvature as the arc-shaped cylinder 111 and is parallel to the arc-shaped cylinder 111. A mounting groove 14 for sliding the fixed block 2 is provided on the inner wall of the arc-shaped cylinder 111, and the mounting groove 14 is communicated with the mounting cavity 4. The first driving member includes a first airbag 5 arranged in the mounting cavity 4, and the fixed block 2 is fixedly arranged on the surface of the first airbag 5, and the first airbag 5 is in an expanded state; after the steel component contacts the fixed block 2, the fixed block 2 is pressed, and the first airbag 5 is pressed, and the first airbag 5 has a tendency to recover the deformation, and drives the fixed block 2 to press against the steel component, and the operation is simple and convenient.

The two arc tubes 111 are respectively fixedly arranged on the inner sides of the second connecting rods 34; when lifting in the arc tube 111, the lifting equipment acts on the lifting ring 31, the lifting ring 31 drives the vertical rod 32 to move up, the vertical rod 32 drives the first connecting rod 33 and the second connecting rod 34 to rotate, and the rotation of the second connecting rod 34 drives the arc tube 111 to rotate and engage, thereby locking the steel structure in the lifting tube 1.

A plurality of first lifting ropes 7 are arranged on the upper part of the reinforcement rod 6, and the connection points with the reinforcement rod 6 are evenly distributed on the reinforcement rod 6. A plurality of second lifting ropes 8 are arranged on the lower part of the reinforcement rod 6, and the lifting ring 31 is lifted at the end of the second lifting rope 8. Under the action of the reinforcement rod 6, the gravity on the steel structure is evenly distributed, thereby facilitating the lifting of the steel structure; and reducing the possibility of tilting of the lifting tube 1.

The limit rod 9 is close to the end of the lifting tube 1. The number of limit rods 9 on one side of the lifting tube 1 is two, and they are staggered with each other. Under the action of the limit rod 9, the end of the lifting tube 1 is sealed. When the steel component is lifted, when the lifting tube 1 is tilted, the steel component abuts against the limit rod 9, thereby reducing the possibility of the steel component falling.

[0027] Reference Figure 2 , Figure 4 and Figure 5In the embodiment of the present application, one end of the limit rod 9 is slidably arranged on the inner wall of the arc tube 111, and the other end of the limit rod 9 is used to abut the relative arc tube 111. The end of the limit rod 9 slides along the inner wall of the arc tube 111, and also includes a driving member for driving the limit rod 9 to slide; when the steel component is hoisted to the desired position, the position of the limit rod 9 is adjusted by the driving member so that the limit rod 9 is in a horizontal state, and then the arc tube 111 is pushed to rotate by the electric push rod to open the hoisting tube 1, thereby facilitating the removal of the steel component.
[0028] Reference Figure 2 , Figure 4 and Figure 5 In the embodiment of the present application, the inner wall of the arc tube 111 is provided with an arc guide rail 10, which is fixedly arranged on the inner wall of the arc tube 111. A slide groove 11 is provided in the arc guide rail 10, and the cross section of the slide groove 11 is T-shaped. The end of the limit rod 9 is slidably engaged in the slide groove 11, and the driving member includes a winding motor 12 arranged at both ends of the arc guide rail 10, and a driving rope 13 is wound on the output shaft of the winding motor 12, and the end of the driving rope 13 is fixedly arranged on the limit rod 9. When adjusting the position of the limit rod 9, the winding motor 12 is started, and the winding motor 12 winds up the driving rope 13, and the driving rope 13 drives the limit rod 9 to move in the arc guide rail 10, and the position of the limit rod 9 is adjusted, and the operation is simple and convenient.
[0029] Reference Figure 2 , Figure 4 and Figure 5 In order to facilitate the storage of the driving rope 13 in the slide groove 11 and facilitate the movement of the limit rod 9, a mounting groove 14 is opened on the side wall of the slide groove 11. The mounting groove 14 has the same curvature as the arc guide rail 10, and the driving rope 13 is placed in the mounting groove 14.
[0030] Reference Figure 2 , Figure 4 and Figure 5 Furthermore, a contact block 15 is provided at the end of the limiting rod 9 for contacting the arc tube 111, and the contact block 15 is used to contact the inner wall of the arc tube 111 or the steel component; under the action of the contact block 15, the contact area between the limiting rod 9 and the arc tube 111 and the steel component is increased, thereby improving the fixing effect on the steel component.
[0031] The implementation principle of a lifting device for connecting and installing a steel member in the embodiment of the present application is as follows: When lifting the steel component, first rotate the two arc tubes 111. The two arc tubes 111 rotate relative to each other to open the lifting tube 1, and then lower the lifting tube 1 to allow the steel component to move relatively into the lifting tube 1. Then lift the lifting tube 1. At this time, the two arc tubes 111 have a tendency to move towards each other and are buckled together to move the steel component into the lifting tube 1. After the steel component is moved into the lifting tube 1, the steel component contacts the fixed block 2 and presses the fixed block 2, so that a groove similar to the contact surface of the steel component is formed on the fixed block 2 arranged in an array. Under the action of the groove, the steel component is fixed in the lifting tube 1, reducing the possibility of the steel component slipping out of the lifting tube 1 and improving the safety of the steel component lifting. After the steel component is located in the lifting tube 1 and is received in the lifting tube 1, the possibility of bending of the steel component is reduced during lifting.
