Description

Technical Field

[0001] The invention relates to the technical field of hoisting equipment, and in particular to a prefabricated assembly type component hoisting device and a hoisting method. Background Art

[0002] Prefabricated components are building components that are prefabricated according to design specifications. These components can be made of materials such as steel, wood or concrete, and are produced in factories or on-site. Prefabricated prefabricated components have a wide range of applications, including prefabricated concrete structures, steel structures, modern wooden structures, etc. The lifting of prefabricated components is one of the important links in the construction of prefabricated buildings. During the actual lifting process, construction personnel should reasonably select lifting equipment and arrange the lifting point positions based on the type of components and the lifting environment to ensure the stability of the component lifting.

[0003] Existing lifting devices usually consist of hooks, steel cables, and hanging columns, among which the hooks and steel cables are used to lift the components, and in most cases the length of the steel cables is fixed. Therefore, during the lifting and transportation process, especially when the acceleration of transportation changes during transportation, due to the inertia of the prefabricated components, the components will tilt, so that each steel cable is subjected to different forces, which may affect the service life of the steel cables. Summary of the invention

A spherical cavity is provided at the central axis of the mounting seat, and a ball head seat is rotatably installed inside the spherical cavity at the bottom.

[0011] Furthermore, the fixing seat is rotatably mounted inside the spherical cavity at the top, and threaded holes are provided on the sides of the fixing seat and the ball head seat that are close to each other.

[0012] Furthermore, a plurality of cross bars are evenly and fixedly connected to the inner wall of the socket, four openings are evenly opened on the side wall of the lower shell, a pulley is rotatably installed inside the opening, and four slings are evenly and fixedly installed on the inner side wall of the upper shell.

[0013] Furthermore, the two sway auxiliary plates are fixedly connected with connecting columns at the central axes at the ends away from each other, and threads are provided at the ends of the connecting columns away from the sway auxiliary plates. The two connecting columns are respectively installed in the corresponding threaded holes through the threads at their ends, and a number of spherical bases are evenly fixedly connected to the edges of the end surfaces on the sides where the two sway auxiliary plates are close to each other, and spherical heads are rotatably installed inside the spherical bases, and connecting rods are fixedly connected to the side walls of the spherical heads, and the ends of the connecting rods away from the spherical heads are fixedly connected to the rotating shafts, and the two sway auxiliary plates are fixedly connected with spherical connecting heads at the central axes at the ends where the two sway auxiliary plates are close to each other.

[0014] Furthermore, a sliding seat is arranged between each two spherical heads that are opposite to each other up and down, and two groups of connecting seats are symmetrically fixedly connected to the side walls of the sliding seat. The upper and lower rotating shafts located on both sides of the sliding seat are respectively rotatably installed inside a group of connecting seats. Several sliding seats are respectively slidably arranged on a corresponding cross bar, and a spring is arranged between the sliding seat and the inner wall of the socket. Several springs are respectively sleeved on a cross bar. A certain angle is formed between each upper and lower two opposite connecting rods, and the angle opening formed by each two opposite connecting rods faces one side of the side wall of the mounting shell.

[0015] Furthermore, a connecting tube is fixedly connected to the central axis of the movable disk, and two plug rods are symmetrically slidably arranged inside the connecting tube. The ends of the two plug rods that are away from each other are fixedly connected to spherical connecting seats, and the spherical connecting seats are rotatably installed on corresponding spherical connecting heads. Deep holes are opened at the ends of the two plug rods that are close to each other, and sliding rods are slidably arranged inside the two deep holes.

[0016] Furthermore, four grooves are evenly arranged on the side wall of the movable plate, an arc groove is arranged in the middle of the side wall of the groove, and a pulley 2 is rotatably installed inside the groove.

[0017] Furthermore, one end of the sling away from the inner wall of the upper shell is wound around pulley 2 and pulley 1 in sequence, and one end of the sling away from the inner wall of the upper shell is fixedly connected to a lifting ring, and the four slings are fixedly connected to one end of the steel cable through the lifting rings.

[0018] Another aspect of the present invention provides a method for hoisting a prefabricated assembly component hoisting device, comprising the following steps:

[0019] Step 1: Use four steel cables to fix the prefabricated components and start the crane to lift the components;

[0020] Step 2: During the transportation of the component, when the motion state of the component changes, the lifting rope is tilted, and the fixing seat at the bottom of the cable installation assembly is rotated and installed inside the spherical cavity, which can reduce the degree of tilt of the component following the lifting rope to a certain extent;

[0021] Step 3: When the fixed seat rotates inside the spherical cavity, the deflection auxiliary plate will tilt at the same time. Through the connection between the two deflection auxiliary plates, the deflection auxiliary plate at the bottom will deflect synchronously, and then the movable plate will be pushed to move through the insertion rod at the same time.

[0022] Step 4. When the motion state of the component changes, with the acceleration direction as the positive direction, the steel cable that passes through first is subjected to greater force, and the movement of the movable plate will cause the sling at that location to extend a longer length from the inside of the mounting shell to compensate for the length of the steel cable. Conversely, the sling on the other side will be shortened, thereby ensuring that the component is in a balanced state and reducing the uneven force on the steel cable.

[0023] The present invention has the following beneficial effects:

[0024] (1) In the process of transporting components, when the motion state of the components changes, the suspension rope will tilt due to the inertia of the components. The bottom fixing seat of the cable installation assembly is rotatably installed inside the spherical cavity. When the suspension rope tilts, the fixing seat rotates, which can reduce the degree to which the components follow the tilt of the suspension rope to a certain extent.

[0025] (2) The present invention provides two deflection auxiliary plates. When the fixed seat rotates inside the spherical cavity, the top deflection auxiliary plate tilts along with it, and the bottom deflection auxiliary plate tilts synchronously and is always symmetrical with the moving disk, thereby ensuring that the two insertion rods are always in a vertical state, thereby ensuring the stability of the moving disk;

[0026] And when the deflection auxiliary plate deflects, the two plug rods move, which will push the movable plate to move synchronously, so as to follow the moving state of the component and adjust the position of the movable plate in real time.

[0027] (3) In the present invention, when the motion state of the component changes, the movable plate will move. Since the movable plate will move, the pulley 2 can be regarded as a movable pulley. Therefore, when the movable plate moves, the sling will extend longer from the inside of the mounting shell to compensate for the length of the steel cable, thereby ensuring that the component is in a balanced state and reducing the uneven force on the steel cable.

[0028] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] A moving plate 5 is arranged between the two deflection auxiliary plates 4 .

[0047] The upper shell 21 and the lower shell 22 are fixedly assembled into a whole by screws, and a slot 211 is provided between the end surface of the upper shell 21 close to the lower shell 22 and the inner wall of the upper shell 21, and a socket 221 is fixedly connected to the side of the lower shell 22 close to the upper shell 21, and the socket 221 is inserted into the slot 211.

[0048] The fixing seat 16 is rotatably mounted inside the spherical cavity 241 at the top, and threaded holes 251 are provided on the sides of the fixing seat 16 and the ball head seat 25 that are close to each other;

[0049] When the motion state of the component changes, the suspension rope will tilt, and the fixing seat 16 will be inside the spherical cavity 241, which can reduce the degree of tilt of the component following the suspension rope to a certain extent.

[0052] Example 2

[0053] See also Figure 5-Figure 6 As shown, a connecting column 41 is fixedly connected at the central axis of the end of the two sway auxiliary plates 4 that is away from each other, and a thread 411 is opened at the end of the connecting column 41 that is away from the sway auxiliary plate 4. The two connecting columns 41 are respectively threadedly installed in the corresponding threaded holes 251 through the threads 411 at their ends, and a plurality of spherical bases 42 are evenly fixedly connected to the edge of the end faces on the side where the two sway auxiliary plates 4 are close to each other. A spherical head 43 is rotatably installed inside the spherical base 42, and a connecting rod 431 is fixedly connected to the side wall of the spherical head 43. The end of the connecting rod 431 that is away from the spherical head 43 is fixedly connected to a rotating shaft 432, and a spherical connecting head 44 is fixedly connected to the central axis of the end where the two sway auxiliary plates 4 are close to each other.

[0054] A sliding seat 45 is provided between each of the two spherical heads 43 facing each other, and two groups of connecting seats 451 are symmetrically fixedly connected to the side walls of the sliding seat 45. The upper and lower rotating shafts 432 located on both sides of the sliding seat 45 are respectively rotatably installed inside a group of connecting seats 451. Several sliding seats 45 are respectively slidably arranged on a corresponding cross bar 26. A spring 46 is provided between the sliding seat 45 and the inner wall of the socket 221. Several springs 46 are respectively sleeved on a cross bar 26. A certain angle is formed between each of the two upper and lower opposite connecting rods 431, and the angle opening formed by each of the two opposite connecting rods 431 faces one side of the side wall of the mounting shell 2.

[0055] The two deflection auxiliary plates will tilt at the same time, and the two deflection auxiliary plates 4 will always be symmetrical with the movable plate 5, which will drive the two insertion rods 52 to move. Through the setting of the sliding rod 55, the stability of the two insertion rods 52 can be increased, so that the movable plate 5 can be pushed to move through the insertion rod 52.

[0056] Example 3

[0057] See also Figure 7-Figure 8 As shown, a connecting tube 51 is fixedly connected to the central axis of the movable disk 5, and two plug rods 52 are symmetrically slidably arranged inside the connecting tube 51. The ends of the two plug rods 52 that are away from each other are fixedly connected to spherical connecting seats 53, and the spherical connecting seats 53 are rotatably installed on the corresponding spherical connecting heads 44. The ends of the two plug rods 52 that are close to each other are provided with deep holes 54, and sliding rods 55 are slidably arranged inside the two deep holes 54.

[0058] Four grooves 501 are evenly formed on the side wall of the moving plate 5, an arc groove 502 is formed in the middle of the side wall of the groove 501, and a pulley 56 is rotatably installed inside the groove 501;

[0059] When the motion state of the component changes, the movable plate 5 moves, causing the sling 29 there to extend a longer length from the inside of the mounting shell 2 to compensate for the length of the steel cable 3, thereby ensuring that the component is in a balanced state and reducing the uneven force on the steel cable 3.

[0060] When in use, first use four steel cables to fix three pairs of prefabricated components, then start the crane to lift the components for mechanical transportation;

[0061] In the process of transporting components, when the motion state of the components changes, the suspension rope will tilt due to the inertia of the components. The fixing seat 16 at the bottom of the cable installation assembly 1 is rotatably installed inside the spherical cavity 241. When the suspension rope tilts, the fixing seat 16 rotates, which can reduce the degree of tilt of the components following the suspension rope to a certain extent.

[0062] When the fixed seat 16 rotates inside the spherical cavity 241, the top sway auxiliary plate 4 will tilt at the same time. Through the connection between the two sway auxiliary plates 4, the top sway auxiliary plate 4 will drive the connecting rod 431 to rotate when it tilts, and the angle between the two opposite connecting rods 431 will change. The sliding seat 45 will slide along the cross bar 26, and a part of the spring 46 will be compressed. At the same time, due to the movement of the sliding seat 45, the bottom connecting rod 431 will be pulled to rotate, and the bottom sway auxiliary plate 4 will be synchronously offset, and the two sway auxiliary plates 4 will always be symmetrical with the moving disk 5. When the sway auxiliary plate 4 deflects, the two insertion rods 52 will be driven to move. The setting of the sliding rod 55 can increase the stability of the two insertion rods 52, so that the moving disk 5 can be pushed to move by the insertion rod 52.

[0063] When the motion state of the component changes, with the acceleration direction as the positive direction, the steel cable 3 that passes through first is subjected to a greater force, and the movement of the movable plate 5 will cause the sling 29 at that location to extend a longer length from the inside of the mounting shell 2 to compensate for the length of the steel cable 3. Conversely, the sling 29 on the other side will be shortened, thereby ensuring that the component is in a balanced state and reducing the uneven force on the steel cable 3.

[0064] Example 4

[0065] See also Fig. 9 As shown, a method for hoisting a prefabricated assembly component hoisting device comprises the following steps:

[0066] Step 1: fix the prefabricated components with four steel cables 3, and start the crane to lift the components;

[0067] Step 2: During the transportation of the component, when the motion state of the component changes, the suspension rope tilts, and the bottom fixing seat 16 of the cable installation assembly 1 is rotated and installed inside the spherical cavity 241, which can reduce the degree of tilt of the component following the suspension rope to a certain extent;

[0068] Step 3: When the fixing seat 16 rotates inside the spherical cavity 241, the deflection auxiliary plate 4 will tilt at the same time. Through the connection between the two deflection auxiliary plates 4, the bottom deflection auxiliary plate 4 will deflect synchronously, and then the movable plate 5 will be pushed to move through the insertion rod 52 at the same time.

[0069] Step 4. When the motion state of the component changes, with the acceleration direction as the positive direction, the steel cable 3 that passes through first is subjected to a greater force, and the movement of the movable plate 5 will cause the sling 29 at that location to extend a longer length from the inside of the mounting shell 2 to compensate for the length of the steel cable 3. Conversely, the sling 29 on the other side will be shortened, thereby ensuring that the component is in a balanced state and reducing the uneven force on the steel cable 3.
