[0030] The following is combined with Figure 1-9 The present application is further described in detail.

[0031] Please refer to Figure 1 and Figure 8, a prefabricated building component hoisting equipment, including a connecting mechanism 1, on which four X-shaped beam assemblies 2 are arranged, on which a traction mechanism 3 is arranged, and on which a wire harness assembly 4 is also arranged for cooperating with the traction mechanism 3 to limit the building component. The four beam assemblies 2 are mounted on the connecting mechanism 1 in an X shape, and after the traction mechanism 3 is connected to an external fixing part (a special hook or other clamps adapted to the building component), the external fixing part is locked with the building component, and the traction mechanism 3 is guided by the wire harness assembly 4, so that the four traction mechanisms 3 can cooperate with each other to hoist the building component.

[0032] See also Figure 1 , Figure 2 , Figure 3 The connection mechanism 1 includes two upper and lower connection seats 11 in a disc structure, the two connection seats 11 are connected to each other by a connecting shaft 12, and a first locking assembly 13 is provided between the two connection seats 11. Two symmetrical arc grooves 111 are provided on the outer wall of the connection seat 11, and a first guide rod 14 in an arc structure is fixedly provided in the arc groove 111. The first guide rod 14 is connected to the corresponding cross beam assembly 2, and a second locking assembly 15 for limiting the cross beam assembly 2 is provided on the connection seat 11. The first locking assembly 13 locks the relative positions of the upper and lower connection seats 11 so that the two cannot rotate relative to each other, and the second locking assembly 15 can limit the cross beam assembly 2 and lock it on the connection seat 11.

[0033] See also Figure 3The first locking assembly 13 includes a plurality of second guide rods 131, which are fixedly arranged on the lower side wall of the upper connecting seat 11 and are evenly distributed along the circumferential direction of the connecting seat 11; a locking ring 132 is slidably connected between the plurality of second guide rods 131; a plurality of first positioning pins 133 evenly distributed along its circumferential direction are fixedly arranged on the edge of the lower side wall of the locking ring 132; a plurality of positioning grooves evenly distributed along its circumferential direction are provided on the edge of the upper side wall of the lower connecting seat 11; the first positioning pins 133 are slidably plugged into the positioning grooves; a plurality of first springs 134 evenly distributed along the circumferential direction of the locking ring 132 are fixedly connected between the upper side wall of the locking ring 132 and the lower side wall of the upper connecting seat 11. The upper and lower connecting seats 11 rotate through the connecting shaft 12, and the locking ring 132 moves downward under the action of the first spring 134, so that the first locating pin 133 is inserted into the locating groove on the upper side wall surface of the lower connecting seat 11, so that the two are locked. When necessary, the operator can push the locking ring 132 upward to disengage the first locating pin 133 from the locating groove, thereby releasing the lock on the connecting seat 11, so that the upper connecting seat 11 can be rotated to adjust the position, and after adjusting to the appropriate position, release the locking ring 132, so that the first locating pin 133 on the locking ring 132 can be inserted into the corresponding locating groove again for locking.

[0034] See also Figure 1 , Figure 2 , Figure 3 and Figure 4A cavity 112 communicating with two adjacent arc grooves 111 is provided inside the connecting seat 11, and a through hole communicating with the cavity 112 is provided on the surface of the connecting seat 11 on the side away from the connecting shaft 12. The second locking assembly 15 includes a locking plate 151 slidably arranged in the cavity 112, and a pressing column 152 is fixedly arranged on the side of the locking plate 151 close to the through hole, and one end of the pressing column 152 is slidably connected with the through hole. A plurality of second springs 153 are fixedly arranged on the side of the locking plate 151 away from the through hole, and one end of the second spring 153 away from the locking plate 151 is fixedly connected to the inner wall of the cavity 112. A connecting plate 154 is provided on the crossbeam assembly 2, and a positioning hole is provided on the surface of the connecting plate 154. A plurality of second positioning pins 155 are provided at a position facing each arc groove 111 on the side of the locking plate 151 close to the through hole, and the plurality of second positioning pins 155 are evenly distributed along the arc direction of the arc groove 111, and the positioning holes are slidably plugged with the second positioning pins 155. The locking disk 151 is acted upon by the second spring 153 so that the second locating pin 155 on the locking disk 151 can be plugged into the locating hole on the corresponding connecting plate 154, so that the connecting plate 154 cannot rotate, and the beam assembly 2 connected to the connecting plate 154 cannot rotate independently. When the staff pushes the end of the pressing column 152 with force, the pressing column 152 drives the locking disk 151 to slide in the cavity 112, so that the second locating pin 155 originally inserted into the locating hole slides and finally separates the second locating pin 155 from the locating hole, thereby releasing the limit of the beam assembly 2, so that the beam assembly 2 can rotate around the center of the circle of the connecting seat 11, thereby adjusting the position of the traction mechanism 3 on the beam assembly 2 independently.

[0035] In order to facilitate the adjustment of the traction mechanism 3 according to the position of the hoisting point on the building component, when the hoisting point on the building component is a symmetrical point, the first locking component 13 is used to release the limit between the upper and lower connecting seats 11, so that the upper and lower connecting seats 11 can rotate relative to each other, driving the two symmetrical beam assemblies 2 on the connecting seats 11 to rotate together, and adjusting the position of the beam assembly 2 to a suitable position; when the hoisting point on the building component is asymmetrical, the second locking component 15 is used to release the limit of the corresponding beam assembly 2, so that the corresponding beam assembly 2 can rotate and adjust the angle with the center of the connecting seat 11, thereby adjusting the position of the corresponding traction mechanism 3, so that the hoisting point of the traction mechanism 3 has a higher degree of freedom.

[0036] See also Figure 1 , Figure 2 , Figure 3 and Figure 4The beam assembly 2 includes a first beam 21, one end of the first beam 21 close to the connecting seat 11 is slidably set in the corresponding arc groove 111, and a connecting plate 154 is fixedly connected to the end surface of the first beam 21 in the arc groove 111, the first guide rod 14 is slidably connected to the corresponding first beam 21, a first slide groove is opened on the lower side of the first beam 21, a guide column 22 is fixedly set in the first slide groove, and a second beam 23 is slidably set in the first slide groove, a second slide groove is opened on the second beam 23, the guide column 22 is slidably set in the second slide groove, and a first screw rod 24 is rotatably set in the second slide groove, and the first screw rod 24 is threadedly connected to the guide column 22. A turntable 25 is rotatably provided at one end of the second beam 23 away from the connection seat 11, and the turntable 25 is fixedly connected to one end close to the first screw rod 24. Guide holes connected to the first slide groove are provided on both the longer side walls of the first beam 21, and a limit pin 26 is slidably connected in the guide hole, and the limit pin 26 is fixedly connected to the side wall of the second beam 23. The limit pin 26 can move synchronously in the guide hole when the second beam 23 slides, and when the second beam 23 moves to the limit position, the second beam 23 is prevented from completely moving out of the first beam 21. The staff controls the turntable 25 to rotate so that the first screw rod 24 rotates, thereby driving the second beam 23 to slide relative to the first beam 21, and adjusting the position of the traction mechanism 3.

[0037] See also Figure 4 and Figure 5 The second crossbeam 23 is provided with a moving channel 27 extending along its length and having a rectangular structure. A sliding hole is provided at the lower side of the moving channel 27. Two groups of first tooth plates 28 symmetrically distributed and equal in length to the moving channel 27 are fixedly arranged on the lower inner wall of the moving channel 27. A slide seat 29 is slidably connected in the moving channel 27. Two groups of second tooth plates 30 symmetrically distributed are fixedly arranged on the lower side wall of the slide seat 29. The second tooth plates 30 are engaged with the first tooth plates 28 below, and the slide seat 29 is connected to the traction mechanism 3. The staff lifts the slide seat 29 upwards by using a tool, so that the second tooth plate 30 below the slide seat 29 is separated from the first tooth plate 28 below, and then controls the slide seat 29 to move and adjust to a suitable position in the moving channel 27, and then puts the slide seat 29 down again, so that the second tooth plate 30 below the slide seat 29 is engaged with the first tooth plate 28 in the moving channel 27 again, so as to limit the slide seat 29.

[0038] In order to further facilitate the adjustment of the traction mechanism 3 according to the position of the lifting point of the building component, the traction mechanism 3 is installed on the slide 29, and the slide 29 can move on the second beam 23. At the same time, the second beam 23 itself can also move relative to the first beam 21. The traction mechanism 3 on each beam assembly 2 can slide in two stages, so that the traction mechanism 3 can be adjusted more flexibly according to the position of the lifting point of the building component.

[0039] See also Figure 1 , Figure 4 , Figure 5 and Figure 6 The traction mechanism 3 includes two mounting posts 31 fixedly connected to the lower side wall of the slide seat 29, a pulley block 32 is commonly arranged between the two mounting posts 31, a driving assembly 33 is arranged on the pulley block 32, and a connecting buckle 34 is also arranged on the pulley block 32. The pulley block 32 includes two pulley seats 321 symmetrical in upper and lower directions, a rotating shaft 322 is rotatably arranged on the pulley seat 321, two pulley bodies 323 are fixedly arranged on the rotating shaft 322, a traction rope 324 is commonly sleeved between the four pulley bodies 323, one end of the traction rope 324 is fixedly connected to any one of the upper pulley bodies 323, and the traction rope 324 is slidably sleeved on the other three pulley bodies 323, and the other end of the traction rope 324 is fixedly connected to the lower side wall of the upper pulley seat 321, and the connecting buckle 34 is fixedly connected to the lower side wall of the lower pulley seat 321. The driving assembly 33 includes a worm wheel 331 fixedly connected to one end of the upper rotating shaft 322, and a worm 332 is meshed on the worm wheel 331 and is rotatably arranged on the side wall of the upper pulley seat 321 through a connecting plate. A motor 333 is fixedly arranged on the mounting column 31 near the worm 332, and the output shaft of the motor 333 is fixedly connected to one end of the worm 332. The first end of the traction rope 324 is fixed to one of the upper pulley bodies, and then the traction rope 324 is sleeved on the surface of the pulley body 323 directly below it, and then the traction rope 324 is sleeved on the surface of another upper pulley body 323, passes through the pulley body 323, and then sleeved on the surface of the pulley body 323 below it, and then the end of the traction rope 324 is fixed to the lower side wall of the upper pulley seat 321. The worm 332 is driven to rotate by the motor 333, so that the worm wheel 331 drives the rotating shaft 322 on the upper pulley seat 321 to rotate. Since one end of the traction rope 324 is fixedly connected to one of the pulley bodies 323 on the rotating shaft 322, the traction rope 324 is wound around the pulley body 323 along with the body of the rotating shaft 322. At the same time, the other three pulley bodies 323 cooperate to gradually move the lower pulley seat 321 upward, thereby pulling the corresponding lifting point to tilt up. The building component can be controlled to be lifted in an inclined posture during lifting.

[0040] See also Figure 1 , Figure 2 , Figure 7 , Figure 8 and Fig. 9The cable assembly 4 includes four second screws 41 rotatably arranged on the lower side wall of the lower connecting seat 11, and a cable seat 42 is threadedly connected between the four second screws 41. The cable seat 42 is provided with four circumferentially arranged matching grooves, and a circular ring 43 is fixedly arranged on the outer wall of the cable seat 42. A lifting rope 44 is slidably connected to the circular ring 43 section in each matching groove, and one end of the lifting rope 44 is fixedly connected to the corresponding connecting buckle 34. A locking buckle 45 is sleeved on the surface of the lifting rope 44, and a limiting rope 46 is fixedly arranged between two adjacent locking buckles 45. A locking bolt is threadedly arranged on the surface of the locking buckle 45, and the end of the locking bolt contacts the surface of the lifting rope 44. The locking buckle 45 is fixed to the lifting rope 44 by the locking bolt, which is convenient for adjusting the specific position of the limiting rope 46. At the same time, the locking buckle 45 and the limiting rope 46 can be removed from the lifting rope 44 when not needed. A first gear 47 is fixedly provided on the upper side wall of the second screw rod 41 , and a second gear 48 is rotatably provided at the middle of the lower side wall of the lower connecting seat 11 and meshes with the four first gears 47 . A plurality of pushing seats 49 are fixedly provided on the lower side wall of the second gear 48 .

[0041] In order to further improve the stability of building components during hoisting, the staff can push any push seat 49 to rotate the second gear 48, thereby rotating the four first gears 47, controlling the lower cable tie seat 42 to move up or down, adjusting the distance between the cable tie seat 42 and the corresponding building component, and connecting one end of the lifting rope 44 to a fixing part (special hook or special clamp), and then locking it with the lifting point at the bottom of the building component. The upper connecting seat 11 is connected to the rope on the external crane, and the rope on the crane contracts to lift the traction mechanism 3, pulling the lifting rope 44 to tighten. The four lifting ropes 44 are brought closer to each other by the cable tie seat 42, so that the lifting rope 44 can be close to the surface of the building component to limit the position of the building component. At the same time, there is a limiting rope 46 between two adjacent lifting ropes 44, which is also attached to the surface of the building component to limit the position of the building component during hoisting, further improving the stability of the building component during hoisting. When the building component is a large pipe placed vertically or a large rectangular column, such as Figure 8 As shown, after the pipe is erected, the fixings on the lifting rope 44 are clamped on the lower edge of the pipe, and the fixings on the four lifting ropes 44 are connected to the pipe from different directions. When the traction mechanism 3 rises, the lifting rope 44 is tightened by the traction force. At this time, the lifting rope 44 will contact the surface of the pipe, and the limiting rope 46 between the adjacent lifting ropes 44 will fit on the surface of the pipe to limit the position. When the building component is a horizontally placed stone slab, such as Fig. 9 As shown, the fixings on the four lifting ropes 44 are fixedly connected to the lower part of the stone slab from different directions. When the traction mechanism 3 rises, the lifting ropes 44 are tightened by the traction force. At this time, the four lifting ropes 44 can respectively come into contact with the four side walls of the stone slab, thereby limiting the stone slab.

[0042] During specific operation, the four beam assemblies 2 are respectively installed on the connection mechanism 1, and the two connection seats 11 on the connection mechanism 1 are locked by the first locking assembly 13. When the first locking assembly 13 is unlocked, the relative positions of the four beam assemblies 2 can be adjusted, and the beam assembly 2 itself is connected to the connection seat 11 through the second locking assembly 15. When the second locking assembly 15 unlocks the beam assembly 2, the beam assembly 2 can be rotated independently to adjust the position of the corresponding traction mechanism 3. At the same time, the beam assembly 2 itself can be telescopically adjusted to further change the position of the traction mechanism 3, making the position adjustment of the traction mechanism 3 more flexible. After the traction mechanism 3 provided on the beam assembly 2 is connected to the external fixing part (special hook or other clamps compatible with the building component), the external fixing part is locked with the building component, and the traction mechanism 3 is guided by the wire harness assembly 4, so that the four traction mechanisms 3 can cooperate with each other to hoist the building component.
