Description

Technical Field

[0001] This utility model relates to the field of mobile scaffolding technology, specifically a mobile scaffolding for hoisting rooftop mushroom exhaust fans. Background Technology

[0002] In precision manufacturing industries such as glass substrate manufacturing, production workshops are typically designed with a strict positive pressure environment to maintain cleanliness and process stability. However, existing conventional construction methods have significant drawbacks when installing or replacing large equipment such as rooftop ventilation fans. Typically, a fan opening is pre-installed in the roof and normally sealed with a heavy iron cover. During installation, workers must first use hoisting equipment to completely lift the cover and move it aside to create space for hoisting the fan into the opening. This operation leaves the opening completely open for an extended period, compromising the factory's airtightness and causing unorganized air exchange between the inside and outside. This easily introduces adverse factors such as dust, temperature and humidity changes from the outside into the cleanroom, posing a serious threat to the production of precision glass substrates.

[0003] Prolonged opening of the opening will quickly lead to pressure imbalance inside the factory, triggering a sophisticated differential pressure alarm system and causing an emergency shutdown of the production line. Once the production line stops, not only will a large number of glass substrates being produced be scrapped due to process interruption, resulting in huge direct economic losses, but it will also seriously affect the overall production plan and product delivery cycle. In addition, if traditional heavy equipment such as large truck cranes are used for hoisting, not only are the equipment rental and usage costs high, but their large size is often limited by the space layout and load-bearing capacity of the factory roof, resulting in poor operational flexibility and difficulty in adapting to the construction needs of narrow areas inside the factory.

[0004] Therefore, the market urgently needs a specialized device that can safely, economically, and efficiently complete the installation of rooftop fans while maintaining the airtightness of the factory building. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of this section, the abstract and the title of this utility model. Such simplifications or omissions shall not be used to limit the scope of this utility model.

[0006] In view of the problems existing in the above and / or prior art, the present invention is proposed.

[0007] To achieve the above objectives, this utility model provides the following technical solution: The mobile hoisting frame for the roof-mounted mushroom-shaped exhaust fan includes multiple vertical pipes; Multi-layered horizontal tubes are installed along the height direction of the vertical tube and connected to the vertical tube by fasteners to form a frame structure; Multiple inclined tie pipes are installed at an angle on both sides of the frame structure to reinforce the connection between the vertical pipe and the horizontal pipe; The walking wheel set is installed at the bottom of the riser; A hand chain hoist, the top of which is installed on the top of the frame structure by a sling, includes multiple connectors, multiple load-bearing components and multiple chains, wherein each connector is connected to a load-bearing component and each connector is connected to a sling.

[0008] Furthermore, the frame structure is provided with multiple reinforcing pipes, including a first reinforcing pipe, a second reinforcing pipe and a third reinforcing pipe. The second reinforcing pipe is obliquely connected between the vertical pipe and the horizontal pipe to form a diagonal bracing structure.

[0009] Furthermore, the multiple connectors in the hand chain hoist are divided into two groups. One group of connectors is used to fix the cover plate through a load-bearing hook, and the other group of connectors is used to fix the fan through a load-bearing hook.

[0010] Furthermore, the two sets of slings are respectively fixed to the horizontal tube at the top and the first reinforcing tube.

[0011] Furthermore: a load-bearing component is connected to the bottom of the connector, a chain is provided at the bottom of the load-bearing component, and a load-bearing hook is connected to one end of the chain.

[0012] Furthermore: the traveling wheel set includes multiple omnidirectional wheels, and the omnidirectional wheels are detachably connected to the bottom of the riser.

[0013] Compared with the prior art, the beneficial effects of this utility model are: Using the casters, the gantry crane is moved to the pre-reserved opening for the fan on the roof. The casters allow the crane to turn and move flexibly. Then, the two sets of load-bearing hooks of the hand-operated hoists are hooked onto the existing iron cover and the fan's lifting points, respectively. One set of connectors secures the cover with the load-bearing hooks, and the other set secures the fan with the load-bearing hooks. Then, the four hand-operated hoists are operated simultaneously to pull the chains, raising the cover and the fan to a position millimeters above the opening. At this point, the cover still covers the opening to maintain the airtightness of the plant and prevent pressure loss. Subsequently, the crane is manually pushed, and the fan is moved horizontally to directly above the opening using the flexibility of the casters.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0023] Please see Figures 1-3 As shown in the figure, the mobile hanging frame for the roof-mounted mushroom exhaust fan provided in this embodiment of the present invention includes multiple vertical pipes 1, which are arranged vertically; Multi-layer horizontal pipes 2 are installed along the height direction of vertical pipes 1 and are connected to vertical pipes 1 by fasteners to form a frame structure; Multiple inclined tie pipes 101 are installed at an angle on both sides of the frame structure to reinforce the connection between the riser 1 and the horizontal pipe 2; The travel wheel set 3 is installed at the bottom of the riser 1; The top of the hand chain hoist 5 is installed on the top of the frame structure by a sling 8. It includes multiple connectors 51, multiple load-bearing components 52 and multiple chains 53, wherein each connector 51 is connected to a load-bearing component 52 and each connector 51 is connected to a sling 8.

[0024] In this embodiment, there are six vertical risers 1, which are set vertically on the ground. There are three layers of horizontal risers 2, which are evenly distributed along the height of the risers 1 and connected to the risers 1 by scaffolding couplers to form a cuboid frame structure. The traveling wheel set 3 includes six omnidirectional wheels, which are installed at the bottom of the six risers 1. The hand-operated hoist 5 includes four connectors 51 and four load-bearing components 52. The frame structure is composed of two sets of risers 1 and horizontal risers 2 on the left and right sides. On the side of each set, two diagonal tie pipes 101 are installed in parallel. These diagonal tie pipes 101 are also connected to the top horizontal riser 2 at one end and the bottom horizontal riser 2 at the other end by couplers to form a stable triangular support structure. This greatly enhances the rigidity of the connection node between the risers 1 and the horizontal risers 2, effectively disperses the concentrated stress, and greatly enhances the bending and torsional resistance of the connection point. This ensures that the frame does not shake or deform under heavy load, providing a solid and reliable safety guarantee for high-altitude hoisting operations.

[0025] Preferably, the frame structure is provided with multiple reinforcing pipes, including a first reinforcing pipe 4, a second reinforcing pipe 6 and a third reinforcing pipe 7. The second reinforcing pipe 6 is obliquely connected between the vertical pipe 1 and the horizontal pipe 2 to form a diagonal bracing structure.

[0026] In this embodiment, four second reinforcing pipes 6 are fixed to the top of the vertical pipe 1 and the horizontal pipe 2. The second reinforcing pipes 6 are obliquely connected between the vertical pipe 1 and the horizontal pipe 2 on both sides of the frame structure. The third reinforcing pipes 7 are cross-connected between the vertical pipe 1 and the horizontal pipe 2 at both ends of the frame structure to form a diagonal bracing structure to enhance the stability of the frame. They are connected and fixed by scaffolding fasteners.

[0027] Preferably, the multiple connectors 51 in the hand chain hoist 5 are divided into two groups. One group of connectors 51 is used to fix the cover plate through the load-bearing hook 54, and the other group of connectors 51 is used to fix the fan through the load-bearing hook 54.

[0028] In this embodiment, the four connectors 51 in the hand chain hoist 5 are divided into two groups of two connectors each. One group of connectors 51 is connected to the load-bearing sling via a load-bearing hook 54 to fix the original iron cover plate. This group of connectors 51 is fixed to the two first reinforcing pipes 4 at the top via the sling 8, and the hook of the load-bearing sling is hooked on the edge of the iron cover plate. The other group of connectors 51 is connected to the load-bearing sling via a load-bearing hook 55 to fix the fan to be installed. This group of connectors 51 is fixed to the other two first reinforcing pipes 4 at the top via the sling 8, and the hook of the load-bearing sling is hooked on the lifting lug of the fan. The two groups of connectors 51 are symmetrically distributed to ensure that the cover plate and the fan are subjected to uniform force during lifting.

[0029] Preferably, the two sets of slings 8 are fixed to the top horizontal tube 2 and the first reinforcing tube 4, respectively.

[0030] In this embodiment, a hook 52 is provided on the connector 51. The hook 52 is a U-shaped metal part that is connected to the bottom of the connector 51. The bottom of the hook 52 is fixedly connected to the top of the hand chain hoist 53 by bolts to ensure a rigid connection between the lifting assembly 5 and the frame structure.

[0031] Preferably, the bottom of the connector 51 is connected to a load-bearing component 52, the bottom of the load-bearing component 52 is provided with a chain 53, and one end of the chain 53 is connected to a load-bearing hook 54.

[0032] In this embodiment, the chain hoist 5 is a chain hoist with a load-bearing capacity of 1 ton. Each chain hoist 5 has a chain 53 at its bottom, which is wound around the sprocket of the load-bearing component 52. One end of the chain 53 is fixedly connected to a load-bearing hook 54 by welding or bolting. The load-bearing hook 54 is a hook-shaped metal part with its hook facing downward. The load-bearing hook 54 is detachably connected to the hook of the load-bearing sling. When the chain 53 is pulled, the sprocket of the load-bearing component 52 rotates, causing the chain 53 to retract, thereby realizing the lifting and lowering of the load-bearing sling. The chain 53 is 3 meters long to ensure that there is enough operating space during hoisting.

[0033] Preferably, the travel wheel set 3 includes multiple omnidirectional wheels, and the omnidirectional wheels are detachably connected to the bottom of the riser 1.

[0034] In this embodiment, the traveling wheel set 3 includes six omnidirectional wheels, each with a diameter of 200 mm. The wheels are made of rubber and have wear-resistant and shock-absorbing functions. The six omnidirectional wheels are respectively installed at the bottom of the four vertical pipes 1 and below the middle horizontal pipe 2. One omnidirectional wheel is installed at the bottom of each of the four vertical pipes 1, and two omnidirectional wheels are installed below the middle horizontal pipe 2. The omnidirectional wheels are detachably connected to the vertical pipes 1 or horizontal pipes 2 by bolts. When it is necessary to fix the hanger, the bolts can be unscrewed to remove the omnidirectional wheels, or a brake device can be installed on the omnidirectional wheels to ensure the stability of the hanger when it stops.

[0035] The working principle of this utility model is as follows: The traveling wheel set 3 is used to move the gantry to the pre-reserved fan opening on the roof. The casters of the traveling wheel set 3 allow the gantry to turn and move flexibly. Then, the two sets of load-bearing hooks 54 of the hand-operated hoist 5 are hooked onto the existing iron cover plate and the fan's lifting point, respectively. One set of connecting parts 51 is used to fix the cover plate via the load-bearing hooks 54, and the other set of connecting parts 51 is used to fix the fan via the load-bearing hooks 54. Then, the four hand-operated hoists 5 are operated simultaneously to pull the chain 53, raising the cover plate and fan to a higher position. At a position 50 mm from the opening, the cover plate still covers the opening to maintain the airtightness of the plant and prevent pressure loss. Then, the hoist is manually pushed, and the fan is moved horizontally to directly above the opening using the flexibility of the casters. Finally, the hand-operated hoist 5 is reversed to slowly release the chain 53, allowing the fan to be lowered above the foundation of the opening, completing the installation. Throughout the process, the frame structure composed of the riser 1 and the horizontal pipe 2 provides support, and the reinforcing pipe enhances the stability of the frame, ensuring the safety of the hoisting and not significantly affecting the internal pressure of the plant.

Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
