Description

Technical Field

[0001] This application relates to the field of building construction, and particularly to a method for replacing a window cleaning machine. Background Art

[0002] A window cleaning machine is a permanent special equipment for cleaning and maintaining the outer wall facade and daylighting roof of high-rise buildings.

[0003] Currently, tracks are laid on the top of high-rise buildings, and the window cleaning machine is installed on the tracks. The window cleaning machine walks on the tracks to achieve the cleaning work of the glass on the circumferential side of the building. When the window cleaning machine needs to be replaced, usually the window cleaning machine is transported from the building corridor to the roof for disassembly and replacement.

[0004] However, the internal corridors of some high-rise buildings are narrow and small, which is not convenient for transporting large components, that is, it is not suitable for directly transporting the window cleaning machine to the roof. Summary of the Invention

[0005] In order to realize the replacement of the window cleaning machine under the limitation of complex environments, this application provides a method for replacing a window cleaning machine.

[0006] The method for replacing a window cleaning machine provided by this application adopts the following technical solutions:

[0007] A method for replacing a window cleaning machine, the steps are as follows:

[0008] S1: Use the old window cleaning machine to hoist each component of the roof crane to the roof;

[0009] S2: Install the roof crane;

[0010] S3: Use the roof crane to hoist the old window cleaning machine to the ground;

[0011] S4: Use the roof crane to hoist the new window cleaning machine to the roof and install the new window cleaning machine;

[0012] S5: Dismantle the roof crane, and use the new window cleaning machine to hoist the roof crane to the ground.

[0013] By adopting the above technical solutions, use the old window cleaning machine to first hoist each component of the roof crane to the roof, then assemble the roof crane, then dismantle the old window cleaning machine, use the roof crane to hoist each component of the old window cleaning machine to the ground, and then hoist each component of the new window cleaning machine to the roof and assemble it. Subsequently, dismantle the roof crane, and use the new window cleaning machine to hoist the roof crane to the ground, then the replacement of the old and new window cleaning machines can be realized. Since the lifting weight of the window cleaning machine is limited and the roof crane itself has a large mass, using the roof crane to improve the lifting capacity helps to improve the safety performance of the overall lifting; when the internal environment of the high-rise building is complex and the restrictions are large, using this method can safely and efficiently realize the replacement of the old and new window cleaning machines.

[0014] Preferably, in step S1, before hoisting, the old window cleaning machine is first transformed by removing the hanging basket and strengthening the lifting hook and the jib of the old window cleaning machine.

[0015] By adopting the above technical solution, transforming the old window cleaning machine by removing the hanging basket and strengthening the lifting hook and the jib helps to increase the lifting capacity of the old window cleaning machine, and thus helps to ensure the safety factor of subsequent hoisting operations.

[0016] Preferably, the roof crane includes a rotating base, a counterweight boom, a winch and a plurality of jibs. The plurality of jibs are detachably connected to each other in sequence. In step S1, the roof crane is disassembled and then hoisted separately using the old window cleaning machine.

[0017] By adopting the above technical solution, the roof crane is customized, and the jib is divided into a plurality of detachably connected jibs, which increases the disassembly and connection limit of the roof crane. When hoisting each component separately, it helps to reduce the lifting capacity, that is, it helps to further improve the safety factor of hoisting operations.

[0018] Preferably, in step S1, before hoisting the winch, the steel wire rope on the winch is replaced with a hemp rope with a lighter weight, and then the winch is hoisted to the roof top using the old window cleaning machine, and then the roof crane is installed.

[0019] By adopting the above technical solution, since the steel wire rope has a large mass, there is a certain risk if it is hoisted directly together with the winch body. Therefore, replacing the steel wire rope with a hemp rope with a lighter weight helps to reduce the hoisting burden, that is, it helps to improve the safety factor of hoisting.

[0020] Preferably, in step S1, the steel wire rope is hoisted to the roof top using the installed roof crane, and then the hemp rope is replaced with the steel wire rope.

[0021] By adopting the above technical solution, after the steel wire rope is hoisted to the roof separately using the roof crane and then the hemp rope is replaced, the lifting capacity of the roof crane is increased, which helps to ensure the safety factor of subsequent hoisting operations.

[0022] Preferably, the adjacent jibs are connected by flange plates. In step S2, when installing the jibs in sequence, the old window cleaning machine is used to move backward on the roof track to achieve the sequential installation of all the jibs.

[0023] By adopting the above technical solution, during actual hoisting, first hoist the rotating base, the counterweight boom and the winch of the roof crane to the roof and install them. Then hoist the jibs up in sequence and directly install them. Since the jibs are continuously installed and their length is continuously extended, and the old window cleaning machine is installed on the track, during the installation process, the old window cleaning machine moves away from the roof crane continuously, and thus the convenient installation of the jibs can be achieved.

[0024] Preferably, in step S3, the old window cleaning machine is disassembled, and each component of the old window cleaning machine is hoisted to the ground by using a roof crane.

[0025] By adopting the above technical solution, the old window cleaning machine is disassembled, and each component is hoisted to the ground in sequence by using a roof crane, realizing the removal and transportation of the old window cleaning machine.

[0026] Preferably, in step S4, each component of the new window cleaning machine is hoisted to the roof in sequence, and then assembled.

[0027] By adopting the above technical solution, each component of the new window cleaning machine is hoisted to the roof in sequence. First, it reduces the hoisting burden of the roof crane, and sequential hoisting helps to improve the safety factor of hoisting.

[0028] Preferably, in step S5, the steel wire rope on the winch is replaced with a hemp rope, the steel wire rope is hoisted to the ground by using a roof crane, then the roof crane is removed, and each component of the roof crane is hoisted to the ground in sequence by using the new window cleaning machine.

[0029] By adopting the above technical solution, the rope is replaced again, the steel wire rope is removed and hoisted by using a roof crane, with a higher safety factor. Subsequently, the roof crane is removed and hoisted to the ground in sequence, realizing the removal of the roof crane.

[0030] Preferably, in step S5, after each component of the roof crane is hoisted to the ground, the hanging basket is installed on the new window cleaning machine.

[0031] By adopting the above technical solution, the hanging basket is installed on the new window cleaning machine, finally realizing the replacement of the old and new window cleaning machines.

[0032] In summary, the present application includes at least one of the following beneficial technical effects:

[0033] 1. The roof crane is hoisted to the roof by using the old window cleaning machine, and then the old window cleaning machine is hoisted to the ground by using the roof crane, and the new window cleaning machine is hoisted to the roof and installed. In the case of complex internal environment and large restrictions in high-rise buildings, this method is adopted to realize the replacement of the old and new window cleaning machines;

[0034] 2. Before hoisting the winch, the steel wire rope is replaced with a hemp rope first, then the winch is hoisted to the roof, and then the steel wire rope is hoisted to the roof by using a roof crane, and the hemp rope is replaced again. During this process, the quality of the steel wire rope is relatively large, about 1 ton, and the old window cleaning machine cannot be used for hoisting operations. Using this method helps to improve the safety factor of hoisting operations;

[0035] 3. The boom of the roof crane is composed of multiple detachable booms. During hoisting, individual hoisting helps to reduce the hoisting burden of the window cleaning machine, and thus helps to improve the safety factor of hoisting. Brief Description of the Drawings

Specific embodiments

[0039] The following will Figure 1-2 further elaborate on this application in detail.

[0040] The embodiment of this application discloses a method for replacing a window cleaning machine.

[0041] Refer to Figure 1 and Figure 2 , the method for replacing a window cleaning machine is as follows:

[0042] S1: Hoist each component of the roof crane to the roof top using the old window cleaning machine,

[0043] S2: Install the roof crane;

[0044] S3: Hoist the old window cleaning machine to the ground using the roof crane;

[0045] S4: Hoist the new window cleaning machine to the roof top and install the new window cleaning machine using the roof crane;

[0046] S5: Remove the roof crane and hoist the roof to the ground using the new window cleaning machine.

[0047] In the case of complex internal environment and large restrictions in high-rise buildings, hoist the roof crane to the roof top using the old window cleaning machine, then hoist the old window cleaning machine to the ground and the new window cleaning machine to the roof top using the roof crane, and finally hoist the roof crane to the ground using the new window cleaning machine to achieve the replacement of the old and new window cleaning machines.

[0048] In step S1, first modify the old window cleaning machine, remove the hanging basket, and reinforce the hook and boom of the old window cleaning machine, which helps to increase the lifting capacity of the old window cleaning machine, that is, helps to improve the safety factor of the hoisting operation.

[0049] Disassemble the roof crane. Use the old window cleaning machine to lift each component of the roof crane to the roof one by one. The roof crane includes a rotating base 1, a balance arm 2, a winch 3, and multiple boom arms 4. The multiple boom arms 4 are detachably connected to each other. Specifically, flanges are integrally welded at both ends of the boom arm 4, and the detachable connection between the boom arms 4 is achieved through bolt connection between the flanges. The boom arm 4 of this roof crane is specially customized and set to be disassembled in sections, which improves the disassembly limit of the roof crane and helps to reduce the lifting weight of the roof crane, that is, it helps to improve the safety factor during lifting.

[0050] After the roof crane is disassembled and connected, since the quality of the steel wire rope on the winch 3 is relatively large, and according to the actual building height, the length of the steel wire rope will also become longer, and then the quality will also become larger. Therefore, when lifting operations are carried out on the high-rise building, the length of the steel wire rope is long and the quality is very large, and it is impossible to directly lift it using the old window cleaning machine.

[0051] Therefore, it is necessary to replace the steel wire rope on the winch 3 with a hemp rope with a lighter quality. The replacement method is the traditional method and will not be elaborated here; then use the old window cleaning machine to lift each component of the roof crane to the roof in turn.

[0052] In step S2, when installing the boom arm 4, since the roof crane is fixed, use the old window cleaning machine to continuously retreat on the roof slide rail, that is, continuously move away from the roof crane, to achieve the sequential assembly and fixation of the boom arm 4.

[0053] After the roof crane is assembled, use the roof crane to lift the steel wire rope to the roof, and use the steel wire rope to replace the hemp rope to increase the lifting weight of the roof crane, which helps to ensure the safety factor of lifting. Through the method of changing the rope, on the one hand, the problem of the low lifting weight of the old window cleaning machine is solved, and on the other hand, the lifting operation of the steel wire rope is solved.

[0054] In step S3, disassemble and cut the old window cleaning machine to ensure that the smallest unit is within the lifting range of the roof crane, and then use the roof crane to lift each component of the old window cleaning machine to the ground to remove the old window cleaning machine.

[0055] In step S4, lift each component of the new window cleaning machine to the roof in turn, and then assemble them in turn.

[0056] In step S5, remove the steel wire rope on the winch 3, replace it with a hemp rope again, use the roof crane to first lift the steel wire rope to the ground, and then remove the roof crane, and use the new window cleaning machine to lift it to the ground in turn. Finally, install the hanging basket on the new window cleaning machine to complete the installation of the new window cleaning machine.

[0057] The implementation principle of a window cleaning machine replacement method in an embodiment of this application is as follows: First, transform the old window cleaning machine, remove the hanging basket, and reinforce the jib and hook to increase the lifting capacity of the old window cleaning machine. Then disassemble the customized roof crane. The roof crane is specially customized, and its boom 4 is composed of multiple detachably connected parts, which improves the disassembly limit of the roof crane, facilitates hoisting, and reduces the hoisting burden. Replace the steel wire rope on the winch 3 with a hemp rope with a lighter mass. Use the old window cleaning machine to hoist each part of the roof crane to the roof in turn, and then install the roof crane.

[0058] Then use the roof crane to hoist the steel wire rope to the roof. Since the mass of the steel wire rope is large and the lifting capacity of the old window cleaning machine cannot meet the requirement, the method of replacing the rope is adopted to achieve the hoisting of the steel wire rope. Subsequently, replace the hemp rope with the steel wire rope to increase the lifting capacity of the roof crane.

[0059] After that, remove the old window cleaning machine and use the roof crane to hoist it to the ground in turn to achieve the removal of the old window cleaning machine. Then hoist each part of the new window cleaning machine to the roof and install it. After that, remove the steel wire rope of the roof crane, replace it with a hemp rope, use the roof crane to hoist the steel wire rope to the ground, then remove the roof crane, and use the new window cleaning machine to hoist each part of the roof crane to the ground. Finally, install the hanging basket on the new window cleaning machine to complete the replacement of the window cleaning machine.

[0060] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
