Temporary support device for hoisting steel structure components of generator set

Abstract

A temporary support device for hoisting steel structure components of a generator set includes a base, hydraulic cylinder I, a support plate, and an anti-deviation assembly. The support plate is mounted on the base via hydraulic cylinder I. The anti-deviation assembly includes lateral stops and a drive assembly. At least three lateral stops are arranged in a circumferential array above the base, with the lateral stops movably engaged on the base. The drive assembly is located on the base and is simultaneously powered by the lateral stops at its actuating end, used to synchronously drive all lateral stops closer to each other. The height of the temporary support for the steel column can be flexibly adjusted via hydraulic cylinder I to meet different hoisting operation requirements. The anti-deviation assembly can effectively limit the displacement of the steel column laterally, solving the problem of easy tilting of long steel columns in existing technologies. The linkage group not only further connects all lateral stops in series, so that all stops can synchronously play a blocking and supporting role when the steel column tilts, but also provides mutual backstop when a single L-shaped support rod fails, significantly improving support safety.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example: Please see Figures 1 to 2 This utility model provides a technical solution: The temporary support device for hoisting the steel structure components of the generator set includes a base 1, a hydraulic cylinder I2, a support plate 3, and an anti-deviation assembly 4. The support plate 3 is mounted on the base 1 via the hydraulic cylinder I2 and is used to support the steel columns. The anti-deviation component 4 includes lateral stops 41 and a drive component 42. At least three lateral stops 41 are arranged in a circumferential array above the base 1, wherein the lateral stops 41 are movably engaged with the base 1. The drive component 42 is located on the base 1 and is poweredly connected to the lateral stops 41 at its actuating end, for synchronously driving all the lateral stops 41 to move closer to each other. The lateral stops 41 are used to restrict the movement of the steel column laterally, thus preventing the steel column from tilting and collapsing.

[0016] In a preferred embodiment, the drive assembly 42 includes an annular connecting block 421, a hydraulic cylinder II 422, a slider 423, a connecting rod I 424, and an L-shaped support rod 425 as the actuating end. The annular connecting block 421 is vertically and movably mounted on the base 1 via the hydraulic cylinder II 422, forming a vertical sliding pair on the base 1. The sliders 423, in the same number as the transverse stops 41, are arranged in a circumferential array and movably mounted on the base 1 radially. Figure 1 As shown, the upper end of the base 1 is a cylindrical support part, and the radial direction is the radial direction of the cylindrical support part. The annular connecting block 421 is located inside the cylindrical support part. One end of the connecting rod I 424 is hinged to the slider 423, and the other end is hinged to the annular connecting block 421. One end of the L-shaped support rod 425 is provided on the slider 423, and the other end is provided with a transverse stop 41. In this way, the annular connecting block 421 is driven to move up and down by the hydraulic cylinder II 422, and all the sliders 423 can be moved closer or further away from each other by the connecting rod I 424, thereby moving all the support plates 3 closer or further away from each other.

[0017] In a preferred embodiment, the anti-deviation assembly 4 further includes a linkage group 43, which consists of two hinged links. Both ends of the linkage group 43 are respectively hinged to two adjacent transverse stops 41. The linkage group 43 can prevent the steel column from tilting when the support plate 3 is not providing support. It can also connect all the transverse stops 41 in series, so that when the steel column tilts towards a single transverse stop 41, all the L-shaped support rods 425 can simultaneously provide support and restraint. Furthermore, if one L-shaped support rod 425 breaks or fails, the linkage group 43 can ensure that the other L-shaped support rods 425 support the transverse stops 41 on the failed L-shaped support rod 425, thus achieving the purpose of preventing the steel column from tilting.

[0018] In a preferred embodiment, an arc-shaped groove is formed on the surface of the transverse stop 41 that contacts the steel structure component. The two sides of the arc-shaped groove on the surface in contact with the steel structure component are flat. Thus, by setting the arc-shaped groove, it can provide support for both prismatic and cylindrical steel columns.

[0019] In a preferred embodiment, the base 1 is provided with a limiting hole 11 for restricting the movement of the base 1.

[0020] The working principle of this utility model: When using this device, the base 1 is first installed in the designated position through the limiting hole 11. Then, the steel column is hoisted through the middle of the transverse stop 41 and falls onto the support plate 3. Then, the hydraulic cylinder II 422 drives the annular connecting block 421 to move upward. The connecting rod I 424 can drive all the sliders 423 to move closer to each other, thereby driving all the support plates 3 to move closer to each other. This can prevent the steel column from tilting. The hydraulic cylinder I 2 can also adjust the height of the temporarily supported steel column.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
