Description

Technical Field

[0001] The utility model belongs to the technical field of ventilation engineering and electrical engineering, and particularly relates to an adjustable bracket. Background Art

[0002] At present, the installation of air ducts or bridges inside many buildings is a very important part of ventilation engineering and electrical engineering technology. Air ducts or bridges are generally located on the top of the basement or garage of the building structure. Due to the height of the building structure, large lifting equipment cannot enter for installation, and large-scale operations are impossible.

[0003] The entire air duct or bridge is composed of multiple sections. When installing the air duct or bridge, it is necessary to manually lift the air duct or bridge onto the scaffolding, close to its installation height, and then have several workers manually lift it to the precise installation height so that the two sections of the air duct or bridge are connected. At this time, the air duct or bridge is fixed and the two sections of the air duct are connected. This process is repeated in sequence until the entire air duct system is installed. This installation method is manual assembly by construction workers, and its construction efficiency is low, and it requires a large number of construction workers to cooperate. At the same time, the existing technology can also use lifting equipment or supporting equipment to install its air duct or bridge. The lifting equipment is generally a lifting hoist, and the supporting equipment is a lifting vehicle. The lifting equipment and the lifting equipment have high requirements for their installation environment. In the face of an environment where the lifting equipment cannot be installed, the lifting equipment cannot be used. At the same time, the use of a lifting vehicle for construction and installation has a high installation cost. Summary of the invention

[0004] The purpose of the utility model is to provide an adjustable bracket in view of the problems existing in the prior art.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an adjustable bracket, including a pair of support columns, each of the pair of support columns is provided with an adjustment member, each of the lifting members is provided with a support channel steel, the side walls of a pair of support channel steels away from one end of the support columns are close to each other and connected, at least one side wall of the support channel steel is provided with an adjustment hole, the adjustment hole is provided with an adjustment bolt and a fastening nut connecting the pair of support channel steels, and a pair of support channel steels are also provided with movable limit members.

[0006] By adopting the above technical solution, by setting a lifting piece on the support column and allowing the supporting channel steel to be installed on the lifting piece, the user can easily adjust the overall height of the bracket. This design enables the bracket to adapt to different height requirements and enhances the flexibility and applicability of the bracket.

[0007] Optionally, the support column is a hollow column, a bottom plate is installed at the lower end of the support column, and a plurality of fixing holes are opened on the surface of the bottom plate.

[0008] By adopting the above technical solution, the bracket is firmly connected to the ground or other foundation through the fixing holes opened on the surface of the bottom plate, thereby enhancing the stability of the bracket.

[0009] Optionally, the lifting member includes a lifting column movably installed on the inner side of the supporting column, and the side wall of the supporting column is connected with a locking bolt for interfering and limiting the lifting column.

[0010] By adopting the above technical solution, the height of the bracket can be adjusted through the cooperation between the lifting column and the locking bolt.

[0011] Optionally, the supporting channel steel is an L-shaped channel steel, and the two supporting channel steels have the same length, and the length of the supporting channel steel is half the width of the air duct or the bridge plus 30mm-60mm.

[0012] By adopting the above technical solution, by setting the length of the supporting channel steel to half the width of the air duct or bridge plus 30mm-60mm, it can be ensured that the bracket can accurately align and fix the air duct or bridge during installation. The extra length of 30mm-60mm not only provides additional installation space, but also facilitates fine-tuning to ensure the accuracy and stability of the installation.

[0013] Optionally, the length of the adjustment hole is 3-6 times the diameter of the adjustment bolt, the number of the adjustment holes is two, the distance between adjacent edges of the two adjustment holes is 20mm-40mm, and the adjustment hole is located on the center line of the opening surface of the supporting channel steel.

[0014] By adopting the above technical solution, the length of the adjustment hole is 3-6 times the diameter of the adjustment bolt, which provides a larger adjustment space. The user can move in the longer adjustment hole by rotating the adjustment bolt, thereby achieving finer and larger range of adjustments.

[0015] Optionally, the limiting member includes a limiting plate installed on the upper end of the supporting channel steel, the limiting plate is fixedly connected to an end of the supporting channel steel close to a stud, a locking nut is connected to the stud, and a slideway for sliding adjustment of the stud is provided on the surface of the supporting channel steel.

[0016] By adopting the above technical solution, the stud slides in the slideway on the surface of the supporting channel steel, so that the position of the limit plate can be adjusted as needed to limit the moving range of the supported equipment.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. By setting a lifting piece on the support column, the height of the supporting channel steel can be adjusted by moving the lifting column and locking the locking bolt, so that the height can be adjusted according to the installation environment. This height adjustability enables the bracket to maintain the best supporting effect in various application scenarios and improves the flexibility of use. The design of the number, position and length of the adjustment holes allows the user to accurately adjust the position and angle of the supporting channel steel to adapt to air ducts or bridges of different sizes and shapes. Through the setting of the bracket, the number of construction workers is reduced and the installation cost is reduced; 2. A limit piece is set at the upper end of the supporting channel steel, and the air duct or bridge frame can be positioned and installed through the limit plate. After installation, the air duct or bridge frame can be prevented from shifting on the supporting channel steel due to vibration. BRIEF DESCRIPTION OF THE DRAWINGS
