Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and in particular to a synchronous hoisting device for an integral air duct in a large space. Background Art

[0002] An air duct is a pipeline system for conveying air, usually used in ventilation, air conditioning systems in buildings or air handling systems in industrial facilities. Air ducts are usually made of metal, plastic or other durable materials, and their design and layout are intended to effectively convey and distribute air to achieve the purpose of ventilation, air conditioning or exhaust. As a pipeline system for conveying air, air ducts play an important role in construction, industry and other fields, providing good ventilation, air conditioning and air handling effects for the indoor environment. The air duct system is usually installed by splicing multiple groups of air ducts to form a ventilation passage.

[0003] However, the existing large air duct hoisting methods for high spaces have the following problems: (1) Before hoisting large air ducts, it is often necessary for workers to pre-splice several groups of air ducts and then fix the splicing positions through connectors. Although this design method can improve hoisting efficiency, since the suspension brackets for hoisting the air ducts often concentrate on a certain part of the air duct, affected by gravity during hoisting, there may be problems such as lack of bottom support and insufficient synchronization at the connection of the air ducts, resulting in bending and gaps at the connection, affecting subsequent normal use; (2) Although the existing air duct hoisting equipment can achieve the purpose of hoisting several groups of air ducts at one time, its efficiency is still low. Especially for the high-altitude suspension method with a long stroke, there is a lack of a good connection structure between the hoisting components, affecting the stability and safety of the overall air duct structure, and the suspension speed is not easy to control. Therefore, corresponding technical solutions need to be designed to solve the existing technical problems.

[0004] 1. As disclosed in a Chinese patent for an air duct hoisting combination mechanism and its application method (Application No.: CN202411091054.3), the present invention provides an air duct hoisting combination mechanism and its application method. Compared with the traditional vertical pipe reverse installation method in the past, most components can be batch prefabricated in the factory, with good forming effect, saving construction period and reducing material loss; the welded lifting device does not need to be cut and disassembled, is easy to operate, greatly reduces the labor intensity of workers, and improves construction efficiency; using a balance beam to lift the vertical pipe group, and at the same time setting an internal support member inside the air duct to reduce the risk of the vertical pipe group skewing and colliding during lifting, with higher safety; the vertical pipe support can be adjusted in the horizontal and vertical directions, ensuring that the flanged welding part of the air duct can just be placed on the support, with stronger practicability and operability; the group tightening frame can make the flanged parts of the air duct completely aligned and clamped before welding, ensuring welding quality and good economy.

[0005] 2. As disclosed in a Chinese patent for an air duct hoisting structure (Application No.: CN202421278000.3), the present utility model provides an air duct hoisting structure, belonging to the technical field of air duct installation structures, including: a bracket, a cushion block, and a suspension rod. The bracket has an upward-opening installation groove, which is a rectangular groove. The cushion block is also a rectangular cushion block. The cushion block is placed in the installation groove, and the top surface of the cushion block is higher than the top surface of the bracket. The cushion block supports the bottom of the air duct. The suspension rod is installed on the bracket, and the top end of the suspension rod is adapted to be connected to the top wall of the wall. After the cushion block is placed in the installation groove in the present utility model, since the four sides of the installation groove are sealed, the cushion block cannot move in the installation groove. Therefore, the connection between the cushion block and the bracket is very stable, and the cushion block will not displace or fall off when vibrated, thus ensuring the normal operation of the air duct.

[0006] To reduce the occupation of space, air ducts are usually installed at the top of a building by hoisting. When installing large air ducts in some high building spaces, special hoisting equipment is often required to complete the installation.

[0050] Further, the whole air duct 4 is placed on the support tray 32, and the support bracket 31 is placed in the U-shaped clamping plate 234 and fixed by the positioning pin 235.

[0053] Beneficial effects of the further technical solution: The moving wheels 62 can facilitate the movement of the control console 61, which is convenient for transfer and transportation.

[0054] Compared with the prior art, the beneficial effects of the present invention are as follows: The whole air duct 4 is connected to the top of the building body 1 through multiple suspension mechanisms 2 to achieve multi-point suspension of the whole air duct 4. Cooperating with the power distribution cabinet 5 and the control console 6, the hoisting process can be accurately controlled. The synchronous speed regulation mechanism 61 can ensure the synchronous operation of each electric hoist 22, keeping the whole air duct 4 horizontal during the hoisting process, avoiding deformation or inclination of the air duct caused by uneven stress, and greatly improving the safety and accuracy of hoisting; The support mechanism 3 provides a reliable support platform for the whole air duct 4. The support bracket 31 can be spliced and extended according to actual needs to adapt to air ducts of different lengths of the whole air duct 4.

[0055] During construction and use:

[0056] Step 1: Preparation for hoisting and installation of the air duct 41. For the preparation of hoisting and installation of the air duct 41, the staff checks the appearance of each air duct to be hoisted, detects the integrity, deformation and coating of the air duct surface, rejects defective products, retains qualified air ducts, and cleans the inner and outer surfaces of the air duct 41, and reserves the connectors selected for fixing between the air ducts 41.

[0057] Step 2: Splicing and installation of a single hoisting device and several air ducts 41. Place several air ducts 41 to be spliced directly below the suspension mechanism 2, and install the hoisting bracket 23 on one of the air ducts 41, extending to the position of the hook at the lower end of the electric hoist 22 of the suspension mechanism, so that the hook is hung on the eyebolt of the hoisting bracket 23. Then horizontally insert two synchronous support pallets 31 at the bottom of the hoisting bracket 23 and fix them to keep the synchronous support bracket 31 in a horizontal state. Then extend and splice the other air ducts in turn from both ends of the middle air duct. The staff seals and installs the adjacent two air ducts by bolts. Finally, longitudinally move the support tray 32 on the upper part of the support bracket 31 and conduct contact support on the bottom of the air duct to complete the splicing and installation between several air ducts, forming a set of air duct hoisting components.

[0058] Step 3: Synchronized splicing and fixation among several hoisting devices. Reassemble several sets of suspension mechanisms 2 according to the installation method in Step 2, then butt and arrange the several sets of suspension mechanisms 2 and fasten them with bolts, so that the left and right support brackets 31 are installed in an inserted manner. After the butt joint installation is completed, fix the connection part with a limit pin 312, so that the several sets of suspension mechanisms 2 form an integral structure on the horizontal plane.

[0059] Step 4: Synchronized hoisting of the air duct 41 and speed control. When it is necessary to synchronously hoist several sets of suspension mechanisms 2, synchronously control the electric hoists 22 of several sets of hoisting components through the console 6 to achieve the purpose of synchronously lifting the suspension mechanism 2. And each electric hoist 22 also operates independently and makes independent lifting adjustments to each suspension mechanism 22 to prevent adjustment when the overall air duct 4 is unbalanced. And adjust the running speed of the suspension mechanism 2 by controlling the output power of the power distribution cabinet 5. After hoisting the suspension mechanism 2 to the specified height, each air duct hoisting component stops operating, and connect both ends of the assembled overall air duct 4 to the building main body through brackets to complete the hoisting.

[0060] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
