Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of construction, in particular to an installation system for large-scale roof components of a factory building. Background Art
[0002] With the development of society and economic progress, more and more old factories are facing the need for renovation and upgrading. Most of these factories were built in the 20th century, and their structures and facilities can no longer meet the needs of modern industrial production. Through renovation, the production process can be optimized and production efficiency can be improved. Specifically, the spatial layout can be replanned to improve space utilization; equipment and technology can be updated to improve production efficiency and quality; production lines can be added to increase output value. Therefore, the renovation of old factories has become an indispensable part of modern industrial development.
[0003] Taking the transformation of steelmaking plants as an example, without affecting normal production, the transformation can be carried out by reconstructing, expanding and building new buildings on the basis of the original low-span plants to increase production. Since steelmaking plants are relatively long and wide due to process requirements, and steelmaking converters are located in the middle of the plant, it is very difficult to add a tower system to the low-span plant in the middle, which mainly involves the transportation, stacking and installation of a large number of large components, equipment, pipelines and pipe fittings. The conventional method is to select a large lifting machinery station located around the plant for hoisting, or to dismantle the roof system in the same span of the renovated area for hoisting. Obviously, the former method has a high construction cost, low efficiency of long-distance hoisting, and many blind areas across the plant, which poses a particularly high safety risk; the latter method has a long construction period and affects normal production. Summary of the invention
[0004] The technical problem to be solved by the utility model is to provide a system for installing large-scale components of factory roofs, thereby solving the problem of affecting normal production during the installation of large-scale components.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a system for installing large components of factory roofs, including: factory roof purlins, automobile cranes, a capstan winch fixedly connected to the top side of the factory roof purlins, a pulley bracket horizontally parallel to the capstan winch is provided at the top of the factory roof purlins, a slidingly connected moving pulley is provided on the upper surface of the pulley bracket, and the large components hoisted to the moving pulley by the automobile crane, the outer ends of the upper surface of the moving pulley are provided with upward angle steels, and the outer ends of the lower surface of the moving pulley are provided with downward seamless steel pipes. The utility model is suitable for steel structure factories, the roofs of steel structure factories are generally made of roofing color plates, the capstan winch has support feet, the roofs of factories are generally set as inclined planes for the flow of rain and snow, the two vertical fixed support feet, the height of the support feet is determined according to the angle of the inclined plane of the factory roof, so that the capstan winch is horizontally fixed on the factory roof purlins, and the pulley bracket is a portal frame composed of steel sections connected together to form an integral bracket.
[0006] The interior of the capstan winch is provided with a steel rope for rotating and controlling the movement of the mobile pulley. The capstan winch motor is driven to control the rotation of the steel rope, which connects the front and rear ends of the mobile pulley and can be fixed on the mobile pulley with a professional buckle.
[0007] The pulley bracket is provided with a bracket column fixedly connected to the top surface of the purlin, a bracket crossbeam fixedly connected transversely is provided at the middle and upper part of the bracket column, and a bracket longitudinal beam fixedly connected to the bottom surface of the movable pulley is provided at the other end of the bracket column. The length of the bracket column is determined according to the slope of the roof, and the bracket columns are welded at both ends of the bracket crossbeam to form a fixed bracket, and the bracket longitudinal beam is welded on it. The bracket longitudinal beams are welded on the top of the two bracket columns, and the bracket longitudinal beams are two parallel full-length I-beams, so that the bracket longitudinal beams are horizontally fixed on the roof. The horizontal fixation makes it more convenient for the movable pulley to slide smoothly on it.
[0008] The movable pulley comprises a pulley crossbeam, which is provided with more than two fixedly connected pulley longitudinal beams. The front and rear ends of the pulley crossbeam parallel to the capstan winch are provided with outward-facing pulley end ears, the outer ends of the pulley longitudinal beam are provided with upward-facing angle steels, the outer ends of the pulley longitudinal beam are provided with downward-facing seamless steel pipes, the side of the pulley crossbeam where large components are placed is provided with a fixedly connected patterned steel plate, and the other side of the pulley bracket parallel to the capstan winch is provided with a rollingly connected pulley. The pulley crossbeam and the pulley longitudinal beam are welded together to form a frame. The number of pulley crossbeams and pulley longitudinal beams can also be increased inside the frame to increase the structural strength of the frame. The lifting ears at both ends of the pulley can more conveniently connect the steel rope, so that the steel rope can pull the mobile pulley back and forth in parallel. When placing large components on the mobile pulley, the angle steel can prevent the large components from sliding and falling, thereby reducing construction risks. When the mobile pulley moves back and forth parallel to the bracket longitudinal beam, the seamless steel pipe cooperates with the bracket longitudinal beam to prevent the mobile pulley from slipping. The steel rope needs to rotate back and forth when driving the mobile pulley to move, and the pulley can reduce the friction on the steel rope when the steel rope rotates.
[0009] Compared with the prior art, the beneficial effects of the utility model are:
[0010] 1. The purpose of the utility model is to solve the transportation, stacking and installation problems of a large number of large components, equipment, pipelines and pipe fittings. It is characterized in that a positive and negative circulation transportation platform is arranged on the roof of the factory building. The supporting points of the platform are welded on the roof purlins. There is no need to set additional supporting points, thereby reducing construction costs.
[0011] 2. The components are transported to the designated location on the roof and then hoisted, and a seamless connection process is formed during transportation and installation, which avoids the accumulation of a large number of components in the factory and affects the normal production of the owner.
[0012] 3. Use the mobile pulley platform on the roof to transport the components to the installation location and install them directly on the multi-layer platform from bottom to top, avoiding the need to pass through multi-layer platforms and then be installed on high-rise platforms when lifting the components from the ground in the factory, reducing the safety risks of lifting, improving the installation progress, and saving construction time and costs.
