Description

Technical Field

[0001] The invention belongs to the technical field of equipment maintenance and installation, and relates to a system and method for installing and repairing top-level equipment in a closed material yard. Background Art

[0002] In recent years, global environmental protection requirements have become increasingly stringent. Industries such as steel, electricity, and coal have responded proactively by promoting the construction of enclosed material yards to reduce dust pollution caused by open-air material storage. Enclosed material yards, covered by steel or membrane structures, achieve enclosed material storage, significantly reducing dust dispersion and pollution from rainwater erosion. They have become a key facility in the industrial sector's green upgrade efforts.

[0003] Enclosed material yards typically feature large-span designs, with top platforms often exceeding 20 meters in height. This limited space houses not only essential process equipment but also auxiliary facilities such as sprinklers for dust suppression and electrical wiring. However, process equipment such as motors are constantly exposed to harsh environments characterized by high dust and humidity, leading to frequent mechanical wear and electrical failures, necessitating regular inspection and maintenance.

[0004] But the reality is that due to the limitations of the closed material yard structure, large-scale maintenance equipment such as bridge cranes and mobile lifting platforms commonly used in traditional open-air material yards cannot directly enter the top platform area, which brings many difficulties to the inspection and maintenance of the equipment.

[0005] From a safety perspective, existing small-scale maintenance equipment is insufficient for high-altitude work on the top floors of enclosed material yards. Due to the confined space, operators have limited operating space, and even the slightest carelessness can lead to accidents. Furthermore, ventilation conditions within enclosed material yards are relatively poor, and in the high-dust environment, workers are prone to inhaling large amounts of dust over long periods of time, posing a serious threat to their health.

[0006] In terms of maintenance efficiency, due to the lack of suitable maintenance equipment, maintenance personnel often need to spend a lot of time and energy on preparation. For example, setting up temporary maintenance platforms is not only time-consuming and labor-intensive, but also difficult to ensure stability, increasing uncertainty and risk during the maintenance process. Furthermore, due to limited maintenance space, transporting maintenance tools and equipment becomes extremely difficult, further reducing maintenance efficiency.

[0007] From a maintenance quality perspective, existing technologies make it difficult to conduct comprehensive and detailed inspections and maintenance of equipment. Due to the limitations of maintenance equipment, some hidden faults within the equipment are difficult to detect and address in a timely manner. This can lead to sudden equipment failures during operation, disrupting normal production and even causing greater economic losses.

[0008] While the fully enclosed structure of a closed material yard achieves environmental protection goals, it does present new technical challenges for the operation and maintenance of its internal equipment, particularly the urgent need to address the maintenance of equipment at the top floor. Only by overcoming these technical challenges can the stable operation of the closed material yard be ensured, achieving a win-win situation for both environmental protection and production. Summary of the Invention

[0009] In view of this, the purpose of the present invention is to provide a system and method for installing and repairing equipment on the top floor of a closed material yard, which flexibly utilizes the inverted lifting between equipment to realize the installation, repair and replacement of equipment, and solves the problem of repair and installation of high-altitude equipment on the top floor of a closed material yard.

[0010] In order to achieve the above object, the present invention provides the following technical solutions:

[0011] A system for installing and repairing equipment on the top floor of a closed material yard is installed on the top floor platform of the closed material yard, comprising a belt conveyor arranged on the top floor platform, a stacker mounted on the belt conveyor; a curved track is provided at the equipment installation location, an electric hoist is provided on the curved track, and the curved track covers the installation range of the equipment; and further comprising jib cranes arranged at both ends of the top floor platform;

[0012] The jib crane is used to lift the equipment between the ground and the top platform;

[0013] The stacker moves back and forth on the belt conveyor to transport the equipment between the hoisting position and the installation position on the top platform;

[0014] The electric hoist is used to lift the equipment into place during installation.

[0015] Optionally, at least two belt conveyors are sequentially arranged along the length direction of the top platform and are located on both sides of the equipment installation location.

[0016] Optionally, each of the belt conveyors is provided with a stacker.

[0017] Optionally, there are at least four belt conveyors, which are respectively arranged on both sides of the equipment installation location, and the belt conveyors on the same side are parallel.

[0018] Optionally, there are at least two curved tracks, and each of the curved tracks is equipped with an electric hoist.

[0019] Optionally, the device includes a transmission roller and a drive assembly.

[0020] A method for installing and repairing equipment on the top floor of a closed material yard, using any of the above-mentioned systems for installing and repairing equipment on the top floor of a closed material yard;

[0021] A. When installing the equipment, first use the jib crane to lift the equipment from the ground to the top platform. After the stacker moves to the lifting range of the jib crane, the stacker lifts the equipment, and then runs it to the equipment installation position via the belt conveyor. Then, the electric hoist is used to lift the equipment into place.

[0022] B. When carrying out equipment maintenance, the equipment is lifted by the electric hoist on the curved track, and at the same time the stacker moves to the equipment installation position, lifts the equipment and runs it to the maintenance platform for equipment maintenance;

[0023] C. When replacing equipment, the stacker lifts the equipment to be replaced, moves it to the lifting range of the jib crane, and directly lifts it to the ground via the jib crane, and then proceeds to step A to install the new equipment.

[0024] The beneficial effects of the present invention are:

[0025] The present invention flexibly utilizes the transportation between various lifting equipment, which is flexible, convenient, safe and reliable. It solves the problems that have long plagued on-site production from the design source, and effectively solves the problems of maintenance and installation of high-altitude equipment on the top floor of closed material yards that have long plagued on-site production, providing a guarantee for the normal operation of closed material yard equipment in industrial production.

[0026] The system's jib cranes, stackers, and electric hoists work together to form a complete lifting system. The jib crane is responsible for lifting equipment between the ground and the top platform. The stacker travels back and forth on a belt conveyor to transport equipment between the hoisting and installation locations on the top platform. The electric hoist is used to lift and position equipment during installation. The clear division of labor and collaborative operation between each device ensure flexibility throughout the installation and maintenance process, enabling rapid adjustments to the lifting plan based on actual needs and adapting to the installation and maintenance requirements of different equipment.

[0027] The present invention ensures the safety of the equipment installation and maintenance process by rationally planning the layout and operation process of each device. The reverse hoisting method between each device reduces the manual working time in dangerous environments such as high altitudes, thereby reducing the safety risks of operators.

[0028] Thanks to the efficient collaboration between various equipment, equipment installation and maintenance time is significantly shortened. During equipment installation, a jib crane hoists the ground equipment to the top platform, a stacker quickly transports the equipment to the installation location, and an electric hoist promptly lifts it into place. The entire process is seamless, eliminating the inefficiencies associated with traditional maintenance methods due to the difficulties of equipment transportation and lifting. Equipment maintenance and replacement operations can also be completed quickly, improving equipment availability and production efficiency.

[0029] The installation of belt conveyors, curved tracks and other equipment increases the flexibility and scalability of various lifting equipment, and can adapt to the installation and maintenance needs of top-level equipment in closed material yards of different sizes and layouts, while also meeting the installation and maintenance requirements of different types of equipment.

[0046] A method for installing and repairing equipment on the top floor of a closed material yard, using the system for installing and repairing equipment on the top floor of a closed material yard according to any one of the first to third embodiments above;

[0047] A. When installing equipment, first use the jib crane 7 to lift the ground equipment to the top platform 2. After the stacker 6 moves to the lifting range of the jib crane 7 (the stacker 6 can move to the lifting range of the jib crane 7 in advance), the equipment is lifted by the stacker 6, and then moved to the equipment installation position via the belt conveyor 3. Then, the equipment is hoisted into place by the electric hoist 8.

[0048] B. When carrying out equipment maintenance, the equipment is lifted by the electric hoist 8 on the curved track 9, and at the same time, the stacker 6 moves to the equipment installation position, lifts the equipment and runs it to the maintenance platform for equipment maintenance;

[0049] C. When replacing equipment, the stacker 6 lifts the equipment to be replaced, moves it to the lifting range of the jib crane 7, and directly lifts it to the ground through the jib crane 7, and then proceeds to step A to install the new equipment.

[0050] The present invention flexibly utilizes the transportation between various lifting equipment, which is flexible, convenient, safe and reliable. It solves the problems that have long plagued on-site production from the design source, and effectively solves the problems of maintenance and installation of high-altitude equipment on the top floor of the closed material yard 1 that has long plagued on-site production, providing a guarantee for the normal operation of the closed material yard 1 equipment in industrial production.

[0051] The system's jib crane 7, stacker 6, and electric hoist 8, among other equipment, work together to form a complete lifting system. The jib crane 7 is responsible for lifting equipment between the ground and the top platform 2. The stacker 6 travels back and forth on the belt conveyor 3 to transport equipment between the hoisting and installation locations on the top platform 2. The electric hoist 8 is used to hoist the equipment into place during installation. The clear division of labor and collaborative operation between each piece of equipment ensures flexibility throughout the installation and maintenance process, enabling rapid adjustments to the lifting plan based on actual needs to accommodate the installation and maintenance requirements of different equipment.

[0052] The present invention ensures the safety of the equipment installation and maintenance process by rationally planning the layout and operation process of each device. The reverse hoisting method between each device reduces the manual working time in dangerous environments such as high altitudes, thereby reducing the safety risks of operators.

[0053] Thanks to the efficient collaboration between various devices, equipment installation and maintenance time is significantly shortened. During equipment installation, the jib crane 7 hoists the ground equipment to the top platform 2. The maintenance platform on the stacker 6 then quickly transports the equipment to the installation location. The electric hoist 8 then promptly lifts it into place, completing the entire process in one go. This avoids the inefficiencies associated with traditional maintenance methods due to the difficulties of transporting and lifting equipment. Equipment maintenance and replacement operations can also be completed quickly, improving equipment availability and production efficiency.

[0054] The provision of equipment such as the belt conveyor 3 and the curved track 9 increases the flexibility and scalability of each lifting equipment, and can adapt to the installation and maintenance needs of top-level equipment in closed material yards 1 of different sizes and layouts, and can also meet the installation and maintenance requirements of different types of equipment.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions, which should all be included in the scope of the claims of the present invention.
