DETAILED DESCRIPTION

[0038] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present application, and are not intended to limit the present application.

[0039] In the present application, the orientation words such as "up, down, left, right, inner, outer, far, near, front" used without the opposite description generally refer to the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as a limitation of the present application.

[0040] As shown in Figure 1 , an installation platform is shown, which is used for the installation of a steel structure 1, and the installation platform 2 is in sliding connection with the steel structure 1.

[0041] The installation platform 2 comprises a portal frame assembly 22 and a first power device and a second power device connected with the portal frame assembly 22, the second power device is connected to the top of the portal frame assembly 22, the first part of the first power device is connected with the portal frame assembly 22, and the second part is connected with the steel structure 1, so that when the first part moves close to the second part, the first part drives the portal frame assembly 22 to move, and the second part moves under the action of the second power device.

[0042] As shown in Figure 1 , the installation platform 2 of the present application is in sliding connection with the steel structure 1, so that during the assembly process of the steel structure 1, the installation platform 2 can move according to the assembly height requirement of the steel structure 1, and the installation platform can move upward by a part after the steel structure 1 is assembled by a part, until the steel structure 1 is assembled.

[0043] Specifically, as shown in Figure 2 , the installation platform 2 comprises a portal frame assembly 22, a first power device and a second power device. The second power device is installed at the top of the portal frame assembly 22, and the first power device is installed at the middle and lower part of the portal frame assembly 22. Among them, the first power device has two parts, specifically the first part and the second part, the position of the second part is higher than that of the first part, the first part is fixedly connected with the portal frame assembly 22, and the fixed connection can be welding or bolt connection, and the bolt connection is preferred; the second part is connected with the steel structure 1, and the connection is detachable connection so that the second part and the steel structure 1 can be flexibly detached.

[0044] When the splicing workers of the steel structure 1 cannot continue to splice, and need to splice a higher position area, the installation platform 2 needs to be moved to a higher position area to match the steel structure 1, so that the workers can further splice the steel structure 1. Under the action of the self power of the second power device, the second part of the second power device moves relative to the first part, so that the first part moves close to the second part, thereby driving the gantry assembly 22 to move upward. When the second part rises to a certain position area and cannot continue to move, the first part can be detached from the steel structure 1, and under the action of the second power device, the first part is moved to a higher position and connected with the steel structure 1, so that the installation platform 2 moves according to the splicing needs of the steel structure 1 under the action of the two groups of power.

[0045] Further, the first power device is a lifting assembly 23, the first part of the lifting assembly 23 includes a power device, a second cross beam assembly 232 and a third cross beam assembly 233, and the second part includes a first cross beam assembly 231.

When the second cross beam assembly 232 moves close to the first cross beam assembly 231, the second cross beam assembly 232 drives the gantry assembly 22 to move. The relative movement of the first part and the second part drives the relative movement of the gantry assembly 22 and the steel structure 1, so as to realize the displacement change of the gantry assembly 22 to meet the splicing needs of the steel structure 1.

[0047] It should be noted that the lengths of the first cross beam assembly 231, the second cross beam assembly 232 and the third cross beam assembly 233 can be adjusted, and the structure is a telescopic structure, as shown in Figure 3 , so as to improve the adjustability and convenience of the connection of the three cross beams with the gantry assembly 22 or the steel structure 1.

[0048] Further, the steel structure 1 comprises first columns 11 and first beams 12 connected between the first columns 11, the first beams 12 are evenly distributed in the vertical direction of the first columns 11, and the steel structure 1 is fixedly connected with the track 3.

The steel structure 1 is connected by four groups of first beams 12 in the horizontal direction between the four groups of first columns 11, and the connecting pieces can be used to fixedly connect at the connecting position of the first column 11 and the first beam 12 to stabilize the steel structure 1. In order to further improve the stability of the steel structure 1, in the embodiment as shown in Figure 4 , the inclined braces 13 are arranged between the first beams 12 adjacent in the vertical direction, and the inclined braces 13 are distributed in a head-to-tail corresponding manner.

[0050] In order to realize the sliding connection of the steel structure 1 and the gantry assembly 22, the track 3 can be provided for the steel structure 1, and the gantry assembly 22 is provided with a structure matched with the structure of the track 3, as shown in Figure 5 , the track 3 is fixedly connected to the first beam 12 or the first column 11, and preferably the track 3 is fixedly connected to the first beam 12, which can be welded or bolted. It should be noted that the track 3 is also spliced by a segmented structure.

[0051] Further, the gantry assembly 22 comprises second columns 221, the top of the second columns 221 is provided with second beams 222, and the bottom of the second columns 221 is provided with third beams 223, the second power device is fixedly connected with the second beam 222, and the power device is fixedly connected with the third beam 223.

[0052] The gantry assembly 22 is a rectangular frame structure, in the embodiment as shown in Figure 6 , the gantry assembly 22 is composed of two groups of second columns 221 and two groups of beams, wherein the upper beam is the second beam 222 and the lower beam is the third beam 223, and the two groups of second columns 221, the second beam 222 and the third beam 223 are connected end to end, and the connection is fixed connection. Among them, the second beam 222 and the third beam 223 are telescopic structures, and the lengths thereof can be adjusted, so that the gantry assembly 22 can adapt to steel structures 1 of different sizes, and has wide application.

[0053] Among them, the second power device is installed on the second beam 222, and provides power for the movement of the first beam assembly 231 of the lifting assembly 23. The power device of the lifting assembly 23 is installed below the third beam 223.

[0054] Furthermore, a first platform 224 is erected on the third crossbeam 223, and a guardrail 228 is fixedly connected to the first platform 224. A staircase 229 is laid on the second column 221.

[0055] To enable staff to work more conveniently and safely, such as Figure 6 and Figure 7 In the embodiment shown, a first platform 224 is added to the gantry assembly 22. Specifically, the first platform 224 is erected on the third crossbeam 223, and the first platform 224 and the second column 221 are connected by a tie rod 225. Figure 6 As shown. To further improve the safety of workers, a guardrail 228 is fixedly connected to the circumference of the first platform 224, and a staircase 229 is laid on the second column 221 to allow workers to climb up and down, as shown. Figure 7 As shown.

[0056] Furthermore, the end of the second column 221 is fixedly connected with a guide device 227 and a clamping device 226.

[0057] like Figure 6 As shown, the end of the second column 221 is provided with a guide device 227 and a clamping device 226 to allow the gantry assembly 22 to move freely within the track 3. When the gantry assembly 22 moves to the desired position, it can be stabilized on the track 3 for further operation. The number of guide devices 227 and clamping devices 226 can be selected according to the actual working conditions, as long as they can enable the gantry assembly 22 to slide and be fixed on the track 3. Preferably, they are symmetrically arranged at the ends of the two sets of second columns 221. In the embodiment shown in Figure 6, the top of each set of second columns 221 is provided with a guide device 227, and the bottom of each set of second columns 221 is provided with a clamping device 226 and a guide device 227. When the gantry assembly 22 needs to move, the clamping device 226 is released, allowing the gantry assembly 22 to move on the track 3; when the gantry assembly 22 moves to the desired position, the clamping device 226 is used to stably connect the gantry assembly 22 to the track 3. This achieves the targeted movement of the gantry assembly 22. It should be noted that the guide device 227 and clamping device 226 are existing technologies, and their detailed structures will not be described here.

[0058] Furthermore, the power unit includes a mounting frame 234 fixedly connected to the third crossbeam 223, a hoist 236 connected to the mounting frame 234, and the hoist 236 connected to the first crossbeam assembly 231 and the second crossbeam assembly 232 via steel ropes 235.

[0059] like Figure 3The power device is composed of a mounting frame 234 and a lifting machine 236. The mounting frame 234 is fixedly connected with the third cross beam 223 of the gantry assembly 22, and the lifting machine 236 is installed on the mounting frame 234. The lifting machine 236 is connected with the first cross beam assembly 231 and the second cross beam assembly 232 through a steel rope 235, as shown in Figure 3 In the embodiment shown, the first cross beam assembly 231 and the second cross beam assembly 232 are each provided with two groups of cross beams, and a fixed pulley is arranged between the two groups of cross beams. In order to make the connection of the steel rope 235 stable, two groups of fixed pulleys are arranged on the second cross beam assembly 232 so that the steel rope 235 can pass through. Specifically, the lifting machine 236 is connected with the steel rope 235, the steel rope 235 passes through the mounting frame 234, and the steel rope 235 is wound with the two groups of fixed pulleys in the second cross beam assembly 232 and one group of fixed pulleys in the first cross beam assembly 231. Finally, the end of the steel rope 235 extends to the first cross beam assembly 231 and is fixedly connected with a fixing member. The fixing member can be used to fix the steel rope 235 on the first cross beam assembly 231, and the fixing member can be a steel clamp. The lifting machine 236 is a prior art device, and its specific structure will not be described here. The lifting machine 236 can provide power for the displacement change of the first cross beam assembly 231 and the second cross beam assembly 232.

[0060] Under the power action of the lifting machine 236, the steel rope 235 is pulled to drive the second cross beam assembly 232 to rise. The second cross beam assembly 232 is fixedly connected with the third cross beam 223 of the gantry assembly 22, thereby driving the gantry assembly 22 to rise. The third cross beam assembly 233 is fixedly connected with the second upright column 221 of the gantry assembly 22, thereby driving the third cross beam assembly 233 to rise. The first cross beam assembly 231 is connected with the steel structure 1 at this time and does not produce displacement. Thus, the relative movement of the gantry assembly 22 and the steel structure 1 is realized.

[0061] Further, the second power device is a hoisting device 21. The hoisting device 21 includes a base and a winch 212 and a hoisting rod 211 connected with the base. The hoisting rod 211 is provided with a first guide wheel assembly 214 and a second guide wheel assembly 215. The hoisting device 21 further includes an electric supporting rod 216, one end of which is connected with the hoisting rod 211 and the other end of which is connected with the base. The base is arranged as a rotating base 213.

[0062] As Figure 8As shown, the lifting device 21 serves as the second power unit for the installation platform 2, providing power for the movement of the first crossbeam assembly 231 of the lifting assembly 23. The base of the lifting device 21 is fixedly connected to the second crossbeam 222 of the gantry assembly 22. Specifically, the lifting device 21 is powered by a winch 212, which is mounted on the base. The winch 212's wire is wound by a lifting rod 211 and a first guide wheel assembly 214 and a second guide wheel assembly 215 mounted on the lifting rod, thereby achieving the function of lifting external objects. To broaden the application of the lifting device 21, it is also equipped with an electric support rod 216. One end of the electric support rod 216 is connected to the base, and the other end is connected to the lifting rod 211, allowing adjustment of the lifting rod 211's pitch angle. To further enrich the lifting operations of the lifting device 21, the base of the lifting device 21 is set as a rotating base 213, so that the lifting rod 211 can rotate at the same horizontal position, allowing the lifting device 21 to perform lifting operations in all directions.

[0063] Furthermore, the installation platform 2 also includes an outer guide frame 24, which is fixedly connected to the second crossbeam 222 and slidably connected to the steel structure 1.

[0064] like Figure 9 As shown, the outer guide frame 24 is a frame structure, which is both fixedly connected to the second crossbeam 222 of the gantry assembly 22 and slidably connected to the steel structure 1. Figure 1 In the embodiment shown, the outer guide frame 24 is disposed outside the steel structure 1, and its top is connected to the second crossbeam 222 of the gantry assembly 22.

[0065] Furthermore, the outer guide frame 24 includes a third column 241 and a guide column 242. A fourth crossbeam 243 is evenly distributed between the guide column 242 and the third column 241. A second platform is provided on the top of the third column 241. The second platform includes a first support 244 and a second support 245. A third support 246 is connected between the opposing first supports 244. The outer guide frame 24 is fixedly connected to the second crossbeam 222 through the third support 246.

[0066] The outer guide frame 24 can further improve construction safety, specifically, such as... Figure 9In the illustrated embodiment, the outer guide frame 24 is a frame structure formed by guide columns 242 and fourth crossbeams 243 arranged longitudinally and transversely. The guide columns 242 and fourth crossbeams 243 are fixedly connected, which can be welded or bolted, preferably welded. Two sets of third columns 241 are fixedly connected to the fourth crossbeams 243 on opposite sides of the frame structure. First supports 244 and second supports 245 are fixedly connected to the tops of the four sets of third columns 241. The two sets of first supports 244 and two sets of second supports 245 are connected end-to-end to form a rectangular second platform. The space of the second platform is sufficient to allow the base of the lifting device 21 to pass through, so that the base of the lifting device 21 can connect to the second crossbeam 222 of the gantry assembly 22. Third supports 246 are fixedly connected between the opposite first supports 244 of the second platform. Multiple sets of third supports 246 can be provided. Figure 9 In the illustrated embodiment, the third support 246 is configured in two sets, both sets of which are fixedly connected to the second crossbeam 222 of the gantry assembly 22. This fixed connection is preferably bolted. The second platform can also be covered with a slab-like structure that facilitates worker movement, allowing workers to perform construction work on the second platform.

[0067] It should be noted that the sliding connection between the outer guide frame 24 and the steel structure 1 is specifically achieved by fixing a roller assembly 247 to the guide column 242. Multiple sets of roller assemblies 247 can be installed. Figure 9 and Figure 10 In the illustrated embodiment, the roller assembly 247 has rollers, which are connected to the guide column 242 via fixed connectors. The angle distribution of the two sets of rollers needs to match the angle of the outer facade of the first column 11 of the steel structure 1. When the outer guide frame 24 moves with the gantry frame assembly 22, the outer guide frame slides with the steel structure 1. During the sliding process, the two sets of rollers roll on the outer facade of the first column 11 respectively, thereby achieving a sliding connection between the outer guide frame 24 and the steel structure 1.

[0068] like Figure 2 As shown, the installation platform 2 of this utility model is slidably connected to the steel structure 1, and has a lifting device 21, a gantry frame assembly 22, a lifting assembly 23, and an outer guide frame 24.

[0069] The gantry frame assembly 22 consists of a second crossbeam 222, a third crossbeam 223, and two sets of second columns 221 forming a rectangular frame. Guide devices 227 and clamping devices 226 are installed at the ends of the second columns 221. A first platform 224 is laid on the third crossbeam 223, and the first platform is connected to the second columns 221 via diagonal braces 225. When the first platform 224 is rectangular, four sets of diagonal braces 225 can be configured, each connected to one of the four corners of the rectangular first platform 224 to pull the first platform 224 and ensure its stability.

[0070] The lifting assembly 23 has a first cross beam assembly 231, a second cross beam assembly 232, a third cross beam assembly 233, a hoist 236 and a mounting frame 234. The hoist 236 is connected with the second cross beam assembly 232 and the first cross beam assembly 231 through a steel rope 235. Specifically, the first cross beam assembly 231, the second cross beam assembly 232 and the third cross beam assembly 233 are each provided with two groups of cross beams, and a group of fixed pulleys is fixedly connected between the two groups of cross beams of the first cross beam assembly 231, and two groups of fixed pulleys are fixedly connected between the two groups of cross beams of the second cross beam assembly 232.

[0071] The hoist 236 is fixedly connected with the mounting frame 234, and the mounting frame 234 is fixedly connected to the lower part of the third cross beam 223 of the gantry assembly 22. The two groups of cross beams of the second cross beam assembly 232 are arranged above the first platform 224 of the gantry assembly 22 and are fixedly connected with the second upright column 221 of the gantry assembly 22.
