[0035] The technical solutions of the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0036] In the description of the embodiments of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "top", "bottom", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "set" and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific circumstances.

[0037] Reference Figure 1-3An embodiment of the present invention provides a steel structure installation auxiliary device and a construction method thereof. The device includes two corresponding groups of supporting components and a connecting component located therebetween. The two groups of supporting components are connected by a retractable connecting component, and the connecting component can adjust the distance between the two groups of supporting components; each group of supporting components is provided with a liftable supporting platform 1 for supporting and lifting the steel structure; a liftable pressing member 2 is provided above the supporting platform 1 for limiting the top position of the steel structure in the supporting platform 1.

[0038] When using this device to assist in the installation of steel structures, the spacing between the two groups of supporting components can be adjusted according to the length of the steel, and the two ends of the steel can be placed on the supporting platform 1 respectively. The supporting platform 1 and the steel can be lifted to the specified installation height, and then the pressure piece 2 can be lowered to limit the top of the steel to prevent it from tilting and shifting during the installation and connection process.

[0039] In this embodiment, a mounting seat 4 is provided in the supporting assembly, a connecting seat 3 is provided in the connecting assembly, the mounting seat 4 and the connecting seat 3 are connected by a first telescopic rod 5, and the bottoms of the mounting seat 4 and the connecting seat 3 are both provided with moving wheels 6. The number of the first telescopic rods 5 can be configured according to actual use requirements. For example, in this embodiment, two parallel first telescopic rods 5 are respectively provided on both sides of the connecting seat 3, respectively used to connect the mounting seats 4 on both sides, so as to improve the connection stability between the connecting seat 3 and the mounting seat 4. In addition, the first telescopic rod 5 can also play a guiding role in the process of adjusting the distance between the two groups of mounting seats 4, so as to ensure the position correspondence of the mounting seats 4 on both sides.

[0040] The moving wheels 6 at the bottom of the mounting seat 4 and the connecting seat 3 each have at least one self-locking wheel, which can be locked after being moved to the desired position; the first telescopic rod 5 can be an electric telescopic rod or a manual telescopic rod, which can be selected according to actual needs, but both should have a locking function. When adjusting the distance between the two sets of mounting seats 4 according to the length of the steel, if the first telescopic rod 5 is an electric telescopic rod, the distance can be adjusted by starting the first telescopic rod 5, and if the first telescopic rod 5 is a manual telescopic rod, the distance can be adjusted by pushing the mounting seat 4 after unlocking the first telescopic rod 5.

[0041] Reference Figure 1-2 The mounting seat 4 is connected with an inverted L-shaped frame 7, the horizontal part of the inverted L-shaped frame 7 is rotatably connected with a transmission screw 8, one end of the transmission screw 8 is connected with a driving motor 9, and a transmission nut seat 10 is sleeved in the middle, one side of the transmission nut seat 10 is slidably connected with the vertical part of the inverted L-shaped frame 7, and the other side is fixedly connected with the supporting platform 1. Among them, the driving motor 9 is a forward and reverse motor, preferably arranged on the mounting seat 4 to improve stability, and the other end of the transmission screw 8 can be connected to the inverted L-shaped frame 7 through a bearing and other devices.

[0042] When the height of the supporting platform 1 needs to be adjusted, the driving motor 9 can be started to move forward or reverse to drive the transmission screw 8 to rotate. Due to the sliding limit of the inverted L-shaped frame 7, the transmission nut seat 10 can only move along the axial direction of the transmission screw 8, but cannot rotate around the transmission screw 8, thereby realizing the adjustment of the height of the supporting platform 1.

[0043] The connection method between the transmission nut seat 10 and the inverted L-shaped frame 7 can be an embedded slide groove-slider structure, or the side of the vertical part of the transmission nut seat 10 close to the inverted L-shaped frame 7 can be directly set as a plane, and it is slidably abutted against the vertical part of the inverted L-shaped frame 7. This can not only limit the rotation tendency of the transmission nut seat 10, but also simplify the manufacturing and installation process of the device.

[0044] In this embodiment, a mounting plate 11 is provided at the transverse portion of the inverted L-shaped frame 7, and the pressing member 2 is located between the mounting plate 11 and the supporting platform 1, and is connected to the mounting plate 11 through a cylinder 12. The piston rod of the cylinder 12 is extended toward the supporting platform 1, and the distance between the pressing member 2 and the supporting platform 1 can be changed.

[0045] Reference Figure 3 Each group of supporting platforms 1 at least includes a bottom plate 1.1, a first side plate 1.2 and a second side plate 1.3. The first side plate 1.2 and the second side plate 1.3 are relatively arranged on the bottom plate 1.1, and the two are connected by a second telescopic rod 1.5, one of which is fixedly connected to the bottom plate 1.1, and the other is slidably connected to the bottom plate 1.1; the telescopic direction of the second telescopic rod 1.5 is perpendicular to the telescopic direction of the first telescopic rod 5, that is, the second telescopic rod 1.5 is used to adjust the distance between the first side plate 1.2 and the second side plate 1.3 to adapt to the size of the steel to be supported in the width direction.

[0046] In addition, a guide groove 1.11 is provided on the bottom plate 1.1, and the guide groove 1.11 extends in the same direction as the second telescopic rod 1.5. A guide slide bar 1.6 is provided on the first side plate 1.2 or the second side plate 1.3, and the guide slide bar 1.6 is slidably set in the guide groove 1.11. On the one hand, during the extension and retraction of the second telescopic rod 1.5, the guide slide bar 1.6 slides in the guide groove 1.11, and its sliding direction is the same as the extension and retraction direction of the second telescopic rod 1.5, which can ensure the movement stability of the first side plate 1.2 or the second side plate 1.3, and can reduce the load-bearing capacity of the output end of the second telescopic rod 1.5, reduce the loss, and increase the service life.

[0047] Reference Figure 3 A third side plate 1.4 may also be provided on the separated sides of the two groups of bottom plates 1.1 in the two groups of supporting platforms 1. The third side plate 1.4 is fixedly connected to the bottom plate 1.1 to limit the long end of the supported steel material to prevent it from slipping or falling off along its own length direction to cause a safety accident.

[0048] In specific implementation, it is best to locate the second telescopic member on the side of the third side plate 1.4 away from the connecting assembly, that is, it is the third side plate 1.4 that directly contacts the long end of the steel material, rather than the second telescopic member, to reduce loss and increase service life.

[0049] The method of construction using this device includes the following steps:

[0050] (1) Adjust the distance between the two sets of supporting components according to the length of the steel, and adjust the distance between the first side plate 1.2 and the second side plate 1.3 according to the width of the steel;

[0051] (2) Place both ends of the steel material on the supporting platform 1, with the long ends respectively abutting against the third side plates 1.4 on both sides;

[0052] (3) Using the driving motor 9 to drive the transmission screw 8 to rotate, thereby driving the transmission nut seat 10 to rise, and lifting the supporting platform 1 and the steel to the specified installation height;

[0053] (4) Extend the piston rod of the cylinder 12 and lower the pressing member 2 to limit the top position of the steel material;

[0054] (5) After installing the connecting steel, remove the device in reverse order according to the above steps.

[0055] Compared with the prior art, the beneficial effects of the present invention are as follows: through the cooperation of the driving motor 9 and the supporting platform 1, mechanized lifting of steel can be realized, reducing the manpower consumed in the installation process of the steel structure; through the limiting of the pressure piece 2 and each group of side panels on the supporting platform 1, the position stability of the steel during the installation of the steel structure can be improved, and the installation accuracy and construction safety can be improved; through the first telescopic rod 5 and the second telescopic rod 1.5, the spacing of different structures (the spacing between the two groups of mounting seats 4, the spacing between the first side panel 1.2 and the second side panel 1.3) are respectively adjusted, thereby increasing the scope of use of the device and improving its engineering applicability.

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
