Description

Technical Field

[0001] The utility model relates to the technical field of building construction lifting devices, in particular to a component lifting device for a metal roof. Background Art

[0002] The metal roof needs to be supported by a steel structure, so the steel structure must be built first in the construction project. During the construction of the steel structure, the steel structure is composed of multiple supporting trusses and connecting trusses that are hoisted and leveled in sequence and then welded.

[0003] With the continuous enrichment of architectural shapes and the continuous upgrading of architectural functions, structural forms are becoming more and more diverse, with different shapes and different structural forms emerging one after another, which poses a great challenge to the construction safety and convenience of special-shaped metal roofs. For large-span steel structures, it is difficult to simply hoist the connecting trusses to a position flush with the connecting trusses with existing technology, which will increase the difficulty for workers to weld the supporting trusses and connecting trusses. Utility Model Content

[0004] The utility model aims to solve the above problems and provide a metal roof component lifting device.

[0005] The technical solution of the utility model is achieved in this way:

[0006] The utility model provides a component lifting device for a metal roof, the lifting device is used to lift a second component to a position at the same height as a first component, the lifting device is installed on the first component, and the lifting device comprises:

[0007] A lifter and a steel strand, wherein the lifter is used to lift the steel strand, and one end of the steel strand is fixed to the second member;

[0008] a steel beam, the lifter being mounted on a portion of the steel beam close to the second member;

[0009] A support beam group, used to form a spacing between the steel beam and the upper surface of the first member;

[0010] A guide frame is installed on the steel beam and is used to guide the moving direction of the steel strand.

[0011] The advantages or beneficial effects of the above technical solution include at least:

[0012] By means of the columns and the middle supporting diagonal braces, a height gap is formed between the steel beam and the first component, allowing construction workers to weld the first component and the second component more conveniently. In addition, multiple triangular areas are formed between the middle diagonal braces and the columns, which can further enhance the stability of the steel beam and prevent it from tipping over or collapsing during the hoisting process. In addition, side diagonal braces are installed on both sides of the steel beam to further stabilize the lateral support of the steel beam, making it less likely for the steel beam to tip over to both sides. At the same time, during the hoisting process, due to the gap between the lifter and the first steel beam, the user can more conveniently fine-tune the second component to improve the accuracy of welding.

[0028] Furthermore, the lifting device 20 is installed on the first component 11 to move the second component 12 below to a position flush with the first component 11; specifically, the lifting device 20 includes:

[0029] A lifter 21 and a steel strand 22, wherein the lifter 21 is used to lift the steel strand 22, one end of the steel strand 22 is fixed to the second member 12, and the other end is fixed to a winch, and is used to reel in the steel strand 22, so that the second member 12 moves upward;

[0030] The steel beam 23 and the lifter 21 are installed on the portion of the steel beam 23 close to the second component 12, and a threading hole for accommodating the steel strand 22 is opened on the steel beam 23, and the lifter 21 is installed around the threading hole.

[0031] The support beam group 24 is used to form a gap between the steel beam 23 and the upper surface of the first component 11, so that construction workers can stand on the steel beam 23 and weld the first component 11 and the second component 12; specifically, Figure 3 As shown, the support beam group 24 includes: a column 241, the installation direction of which is perpendicular to the axial direction of the steel beam 23, one end of the column 241 is welded to the first component 11, and the other end is welded to the steel beam 23 to provide vertical support.

[0032] There are two columns 241, which are respectively located in the middle of the steel beam 23 and the end away from the lifter 21 to enhance the support for the steel beam 23; the middle diagonal brace 242 is installed in an inclined manner, with one end of the middle diagonal brace 242 installed on the first component 11, and the other end installed obliquely at the bottom of the steel beam 23. Specifically, there are two middle diagonal braces 242 to form a triangular area between the middle diagonal brace 242 and the column 241 to enhance the support for the steel beam 23.

[0033] The guide frame 25 is installed on the steel beam 23 and is used to guide the moving direction of the steel strand 22 so that the steel strand 22 will not deviate to other directions. In addition, the lifting device 20 further includes: a guide device 26, which is installed on the top of the guide frame 25; the guide device 26 includes: a base 261, which is detachably installed on the end of the guide frame 25; a roller 262, which is rotatably installed on the base 261; the steel strand 22 abuts against the outer periphery of the roller 262, such as Figure 2 As shown, it is used to reduce the friction between the steel strand 22 and the guide frame 25 to avoid damage to the steel strand 22.

[0034] As a further improvement of the above structure, a groove 2611 is formed at the lower end of the base 261 to match the cross section of the guide frame 25, so that the base 261 can be buckled on the end of the guide frame 25. Figure 6As shown; a plurality of bolts 2612 are threadedly connected to the base 261, and the ends of the bolts 2612 can pass through the side walls of the base 261 and abut against the steel strands 22, thereby fixing the base 261 on the guide frame 25, so that the base 261 can be fixed to the guide frame 25. When the user does not need the guide device 26, the bolts 2612 can be rotated outward so that the bolts 2612 leave the position abutting against the guide frame 25, and the base 261 can be separated from the guide frame 25, so that after the lifting is completed, the guide frame 25 can be reused in other places.

[0035] As a further improvement of the above structure, the support beam group 24 further includes: an edge diagonal brace 243, one end of which is fixed to the steel beam 23, and the other end is fixed to the first component 11, so that the side of the lifting device 20 can be better supported to prevent the steel beam 23 from tipping over from the side; in addition, in the horizontal direction, the edge diagonal brace 243 has an acute angle α with the steel beam 23, and in the height direction, the edge diagonal brace 243 has an acute angle β with the steel beam 23, so as to form a triangular structure in the horizontal direction and the height direction, so that the steel beam 23 can be better supported.
