Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, in particular to a bus duct hoisting device. Background Art

[0002] The bus duct hanger plays a vital role in the installation of the bus duct. The bus duct hanger mainly bears the weight of the bus duct, suspending it stably on the building structure to ensure that the bus duct will not be deformed or damaged due to its own weight during operation. It helps to fix the position of the bus duct to prevent it from moving in the horizontal or vertical direction, ensuring the installation accuracy of the bus duct and the reliability of the electrical connection. It consists of a hanger rod, a cross arm and a connector. The hanger rod is usually made of round steel or channel steel and is fixed to the roof of the building with expansion bolts or embedded parts. The cross arm is used to support the bus duct and can be selected according to the width and weight of the bus duct.

[0003] At present, when the bus duct hoisting device is in use, the stability of the round steel after being connected to the roof is poor, and it is easy to swing left and right, which causes the bus duct to swing left and right when connected through the connector, which is very inconvenient when installing other bus ducts. Moreover, the current hoisting device places the bus duct on its top when it is tight, and does not fix the bus duct. When other bus ducts are installed, the current in front is easily offset, so that the bus duct cannot be kept in the center, which easily causes uneven weighing of the round steel.

The outer wall of the threaded sleeve is provided with a diamond-shaped shell for facilitating the rotation of the threaded sleeve.

[0011] Preferably, a threaded hole is provided on the inner wall of the threaded sleeve.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. By setting a limit assembly, the limit sleeve is movably set at the top of the outer wall of the boom. When it moves upward, it can drive the connecting plate to fit the wall surface and be fixed to the wall through the fixing parts, effectively preventing the boom from shaking during use, thereby improving the stability of the entire lifting device, and thus ensuring that the bus duct is installed firmly and reliably, avoiding problems such as poor electrical connection caused by shaking.

[0014] 2. The downward movement of the pressure slider drives the fixed pressure plate to compact the bus duct, preventing it from shifting. The fixing components on both sides of the bottom of the fixed pressure plate, working in conjunction with the threaded rods and threaded sleeves, further enhance the fixing effect of the bus duct, ensuring that the bus duct always maintains a stable position during operation, improving the safety and reliability of the system.

[0015] 3. A limit block is machined inside the connection between the limit sleeve and the boom, so that the limit sleeve can only move up and down and cannot rotate, which makes it convenient for installers to quickly adjust the position of the limit sleeve during the installation process and improves installation efficiency.

[0016] 4. A diamond-shaped shell is provided on the outer wall of the threaded sleeve to facilitate the rotation of the threaded sleeve, so that the degree of compression of the bus duct can be flexibly adjusted according to actual needs, adapting to bus ducts of different specifications and installation requirements, thereby improving the versatility and practicality of the device.

[0017] 5.Anti-slip pad is processed at the center of the top of the support hanger, which increases the friction between the bus duct and the support hanger, further preventing the bus duct from sliding during installation and use, and ensuring the stable operation of the bus duct.
