Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and in particular relates to an auxiliary device for hoisting prefabricated components and its usage method. Background Technology

[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. After the building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, they are transported to the construction site and assembled on-site using reliable connection methods.

[0003] When constructing prefabricated buildings, as the building height increases, prefabricated components often need to be hoisted to a certain height for installation. In existing technologies, the installation of prefabricated components requires the assistance of hoisting mechanisms. However, the hoisting posture of the prefabricated components on the hoisting mechanism often differs from their installation posture, necessitating posture adjustment. Since the posture of prefabricated components cannot be adjusted during hoisting, it can only be adjusted during high-altitude installation, which is difficult and poses safety hazards. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides an auxiliary device for hoisting prefabricated components and a method for using it, which effectively solves the technical problem that the hoisting posture of prefabricated components cannot be adjusted during the hoisting process and overcomes the shortcomings of the prior art.

[0005] The technical solution adopted in this invention is: an auxiliary device for hoisting prefabricated components, comprising:

[0006] The hoisting beam is equipped with a lateral adjustment block, which can move along the length of the hoisting beam;

[0007] The lifting vertical rods are installed at both ends of the lifting horizontal beam and are rotatably connected to the lifting horizontal beam;

[0008] An adjustment seat is located at the end of the hoisting vertical rod away from the hoisting horizontal beam;

[0009] A mounting base is provided on the adjusting base, and the mounting base can move in a direction perpendicular to the lifting beam.

[0010] Furthermore, the hoisting beam is provided with a first elongated hole, which is arranged along the length of the hoisting beam, and the lateral adjustment block is detachably connected to the first elongated hole.

[0011] Furthermore, the lateral adjustment block is provided with a lifting shaft, which is connected to a sling.

[0012] Furthermore, a pivot is provided at the connection between the lifting beam and the lifting vertical rod.

[0013] Furthermore, a connecting screw is provided at the end of the hoisting vertical rod away from the hoisting horizontal beam, the connecting screw is movably connected to the hoisting vertical rod, and the adjusting seat is provided on the connecting screw.

[0014] Furthermore, a ball joint structure is provided at the connection between the hoisting vertical rod and the connecting screw.

[0015] Furthermore, the adjusting seat includes a first horizontal part and a first vertical part, the first horizontal part being threadedly connected to the connecting screw, and the first vertical part being detachably connected to the mounting seat.

[0016] Furthermore, the mounting base includes a second horizontal part and a second vertical part. The second vertical part is provided with a second elongated hole, which is arranged in a direction perpendicular to the hoisting beam. The second elongated hole is detachably connected to the first vertical part.

[0017] Furthermore, the second horizontal section is provided with connecting bolts for connecting prefabricated components.

[0018] The present invention also provides a method for using the prefabricated component hoisting auxiliary device as described above, comprising the following steps:

[0019] Hoist the prefabricated components and compare their hoisting and installation postures.

[0020] Move the lateral adjustment block along the length of the lifting beam, and move the mounting seat along a direction perpendicular to the lifting beam, so that the lifting posture is the same as the installation posture.

In the description of this invention, it should be noted that unless otherwise explicitly specified and limited, the terms "set" and "connected" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two elements. Those skilled in the art can understand the specific meaning of the above terms in this invention through specific circumstances.

[0034] like Figure 1 and Figure 2 As shown in the figure, an embodiment of the present invention provides an auxiliary device for hoisting prefabricated components, including a hoisting beam 1, a hoisting vertical rod, an adjusting seat, and a mounting seat. The hoisting beam 1 is provided with a lateral adjusting block 2, which can move along the length of the hoisting beam 1. The hoisting vertical rod is located at both ends of the hoisting beam 1, including a left lifting rod 31 and a right lifting rod 32, which are rotatably connected to both ends of the hoisting beam 1, respectively. The adjusting seat includes a left adjusting seat 51 and a right adjusting seat 52. The left adjusting seat 51 is located at the end of the left lifting rod 31 away from the hoisting beam 1, and the right adjusting seat 52 is located at the end of the right lifting rod 32 away from the hoisting beam 1. The mounting seat includes a left mounting seat 61 and a right mounting seat 62. The left mounting seat 61 is mounted on the left adjusting seat 51 and can move in a direction perpendicular to the hoisting beam 1. The right mounting seat 62 is mounted on the right adjusting seat 52 and can move in a direction perpendicular to the hoisting beam 1. The lifting equipment is connected to the horizontal adjusting block 2, and the two sides of the precast component 9 are connected to the left mounting seat 61 and the right mounting seat 62 respectively, for lifting the precast component 9. By adjusting the position of the horizontal adjusting block 2 on the lifting beam 1, the tilt of the left and right sides of the precast component 9 can be adjusted. By adjusting the relative position of the mounting seat and the adjusting seat in the direction perpendicular to the lifting beam 1, the tilt of the front and rear sides of the precast component 9 can be adjusted, so that the attitude of the precast component 9 can be adjusted during the lifting process, and the precast component 9 can be lifted in the installation posture, making the installation of the precast component 9 more convenient and faster.

[0035] Specifically, the lifting beam 1 has a first elongated hole, which is located along the length of the lifting beam 1. The transverse adjusting block 2 is detachably connected to the first elongated hole using bolts. The transverse adjusting block 2 is a U-shaped structure, fitted onto the lifting beam 1 with its opening facing upwards. The first elongated hole is located in the middle of the lifting beam 1, and bolts pass through the transverse adjusting block 2 and the first elongated hole for connection and fixation.

[0036] Specifically, the lateral adjusting block 2 is equipped with a lifting shaft 21, which is connected to a sling. The top of the lateral adjusting block 2 is rotatably connected to the lifting shaft 21, which is connected to the sling of the lifting equipment as a lifting point.

[0037] Specifically, a pivot is provided at the connection between the lifting beam 1 and the lifting vertical rod. A first connecting piece and a second connecting piece are bolted to both ends of the lifting beam 1. The first connecting piece is connected to the left lifting rod 31 via a left pivot 71, and the second connecting piece is connected to the right lifting rod 32 via a right pivot 72. When the forces at both ends of the lifting beam 1 are unequal, the left lifting rod 31 and the right lifting rod 32 can rotate around the left pivot 71 and the right pivot 72 respectively, ensuring that the left lifting rod 31 and the right lifting rod 32 always remain vertical.

[0038] Specifically, a connecting screw is provided at the end of the lifting vertical rod away from the lifting horizontal beam 1. The connecting screw is movably connected to the lifting vertical rod, and an adjusting seat is provided on the connecting screw. The connecting screw includes a left screw 41 and a right screw 42. One end of the left screw 41 is movably connected to the end of the left lifting rod 31 away from the lifting horizontal beam 1, and one end of the right screw 42 is movably connected to the end of the right lifting rod 32 away from the lifting horizontal beam 1.

[0039] Preferably, a ball joint structure 8 is provided at the connection between the left screw 41 and the left lifting rod 31, and at the connection between the right screw 42 and the right lifting rod 32. The ball joint structure 8 includes a ball seat 81 and a ball head 82. The ball seat 81 is fixed to the end of the left lifting rod 31 and the right lifting rod 32 away from the lifting beam 1, and has a spherical concave surface. The ball head 82 is fixed to the connection end of the left screw 41 and the right screw 42, and has a spherical surface. A revolute joint is formed between the ball seat 81 and the ball head 82.

[0040] Specifically, both the left adjusting seat 51 and the right adjusting seat 52 include an integrally formed first horizontal part and a first vertical part, which are arranged opposite to each other. The first horizontal part passes through the connecting screw and is threadedly connected to it. The first vertical part has a through hole for detachable connection with the mounting base. By turning the left screw 41 and the right screw 42, the effective vertical length of the left screw 41 and the right screw 42 can be changed.

[0041] Specifically, both the left mounting base 61 and the right mounting base 62 include an integrally formed second horizontal portion and a second vertical portion, which are arranged opposite to each other. The second vertical portion has a second elongated hole, which is positioned perpendicular to the lifting beam 1. The second elongated hole is detachably connected to a through hole on the first vertical portion using bolts. By providing the second elongated hole, the relative position of the mounting base and the adjusting base in the direction perpendicular to the lifting beam 1 can be adjusted.

[0042] Specifically, a connecting through hole is provided on the second horizontal part, and a connecting bolt 10 is provided on the connecting through hole for connecting the reserved hole of the prefabricated component 9.

[0043] A method of using the prefabricated component hoisting auxiliary device as described above includes the following steps:

[0044] S1. Connect the left and right sides of the precast component 9 to the left mounting base 61 and the right mounting base 62 respectively using connecting bolts 10. Connect the lifting equipment to the entire auxiliary device via slings, lift the precast component 9, observe its hoisting posture in the air, and compare it with the required installation posture to determine which direction the precast component 9 needs to be tilted. For example, if the precast component 9 does not tilt before adjustment, such as... Figure 3 and Figure 4 As shown.

[0045] S2. Move the lateral adjusting block 2 along the length of the hoisting beam 1 to adjust the left and right tilt of the precast component 9; move the mounting seat along a direction perpendicular to the hoisting beam 1 to adjust the relative positions of the left adjusting seat 51 and the left mounting seat 61, and the relative positions of the right adjusting seat 52 and the right mounting seat 62, to adjust the front and rear tilt of the precast component 9. By adjusting the left and right tilt and front and rear tilt of the precast component 9, the hoisting posture is made the same as the installation posture. For example, to facilitate installation, it is necessary to tilt the precast component 9 to the right rear. After adjustment, the precast component 9 tilts, such as... Figure 5 and Figure 6 As shown.

[0046] S3. After adjustment, lift the precast component 9 and observe its hoisting posture in the air. Compare it with the installation posture required for installation. If the hoisting posture reaches or is close to the installation posture, no further adjustment is needed. If the hoisting posture has not yet reached or is close to the installation posture, continue to adjust until it reaches or is close to the installation posture.

[0047] The advantages and positive effects of this invention are:

[0048] 1. The prefabricated components achieve posture adjustment during hoisting, so that the hoisting posture reaches or is close to the installation posture. No additional posture adjustment is required during high-altitude installation, which reduces the assembly difficulty and improves the assembly efficiency.

[0049] 2. The structure is simple and the operation is convenient, reducing installation risks.
