Description

Rectangular air pipe hoisting device

Technical Field

The utility model relates to a tuber pipe mounting structure especially relates to a rectangle tuber pipe hoist device.

Background

The air duct is widely applied to ventilation systems, air conditioning systems and dust removal systems, the installation work amount of the air duct in the systems accounts for more than 70%, and the section of the air duct is generally rectangular and has larger volume. In the ventilation and dust removal system, air ducts are installed inside buildings, mainly on the roofs and facade walls inside the buildings, as ducts for air delivery and distribution. The section of the air pipe is generally rectangular, the wall thickness is smaller, and the length of a single air pipe is about 1.45 meters. The size of the industrial factory building is 84 meters multiplied by 85 meters multiplied by 16.7 meters, and the width of a single span of the factory building is 27 meters. The installation amount of the whole system air pipe is thousands of sections, so that the installation efficiency is very important to the cost of the whole project. The air pipe mounting height is 16.5 meters from the ground, after the air pipe is lifted to the mounting height at a preset position, an operator needs to mount a cross arm at the bottom of the air pipe through the ascending operation platform, and the cross arm is connected with a suspender arranged on a roof, so that the air pipe is fixed at the preset position.

At present, no hoisting device integrating the air pipe with the manual operation platform is provided, and the installation and construction of the air pipe mainly have two modes: firstly, after two sections of air pipes are connected on the ground, the air pipes are lifted to a roof by using a hydraulic lift truck, an operator installs the cross arms of the air pipes, the air pipes of the whole system are installed, and the hydraulic lift truck needs to be lifted ten thousand times; and secondly, after the two sections of air pipes are connected on the installation projection ground, the air pipes are lifted to the roof by using the hoist, and the operators install the cross arms of the air pipes by using the ascending vehicle. Due to the two modes, the length of the air pipe connected to the ground is short, so that the air pipe needs to be lifted or pulled for multiple times in the installation of the whole system, the auxiliary time is increased, and the installation efficiency of the air pipe is greatly reduced; meanwhile, when a worker installs the cross beam, the auxiliary operation time occupies a large amount of time of the whole project, and meanwhile, the worker does not have a special operation platform, so that the operation is inconvenient, the efficiency is low, the operation safety is not high, and the progress requirement and the cost control of a project cannot be met; during installation, construction tools such as scaffolds need to be moved repeatedly, the occupied area is large, and integral hoisting cannot be performed. Especially for reconstructed and expanded large-scale markets and industrial plants, under the condition of not influencing on-site office work and production, the method needs to occupy less area, and is particularly important for realizing efficient and safe construction. The two operation modes are low in operation efficiency and high in labor intensity of workers, and potential safety hazards exist in personnel and are not beneficial to improving the production efficiency.

Among the prior art tuber pipe integral hoisting device has 3: (1) CN 211141292U "a bracket special for integral hoisting of air duct" utility model patent; (2) CN203865935U 'wind pipe integral hoisting device'; (3) CN215981203U "an tuber pipe integral hoisting structure" utility model patent. The description of the prior art is as follows:
