Description

Technical Field

[0001] The utility model relates to the technical field of air duct installation in a steel structure grid, in particular to an air duct sliding device in a steel structure grid. Background Art

[0002] There are generally certain difficulties in the installation of air ducts in steel structure grids. There are several ways to install air ducts in traditional steel structure grids, including setting up a full-frame and an operating platform at the bottom, laying an operating platform on the lower chord of the grid, and using machines such as aerial platforms. The aerial platform operation and installation is the most common installation method. During the installation, it is necessary to place tracks and support plates on the aerial platform, lift the aerial platform to the corresponding height, and then move the air duct away from the support plate for installation.

[0003] However, in the existing equipment, the support plate does not have a guiding function. In order to prevent scratches caused by friction between the air duct and the support plate, multiple people are required to lift the air duct and move the air duct to a designated location before installation. This not only increases the difficulty of installation, but also increases the workload of the installers. For this reason, a sliding device for air ducts in a steel structure grid is proposed. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a sliding device for air ducts in a steel structure grid.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a duct sliding device in a steel structure grid, comprising a limiting track, a supporting leg is fixedly provided at the bottom of the limiting track, a plurality of cross bars are fixedly provided on the limiting track, a supporting plate is movably provided at the top of the limiting track, a plurality of mounting grooves are provided at the top of the supporting plate, guide rollers are movably provided in the plurality of mounting grooves, and two fixed structures are provided on the top of the supporting plate.

[0010] As a further description of the above technical solution:

[0011] An anti-skid pad is fixedly provided at the bottom of the pressing plate. The anti-skid pad is made of rubber and has a thickness of two centimeters.

[0012] As a further description of the above technical solution:

[0013] The bracket comprises a connecting rod and a buckle, wherein the connecting rod and the buckle are fixedly connected, and a slope is provided on one side of the buckle and the card block that are close to each other, and the slope on one side of the buckle is parallel to the slope on one side of the card block.

[0016] The utility model has the following beneficial effects:

[0017] 1. Compared with the prior art, the air duct sliding device in the steel structure grid is provided with installation grooves and guide rollers. When the height of the air duct matches the installation position, the installer does not need to lift the air duct. The air duct can be directly pushed to remove it from the support plate and move it to the installation position, which can reduce the labor intensity of relevant personnel and reduce the difficulty of installation.

[0018] 2. Compared with the prior art, the air duct sliding device in the steel structure grid is provided with a telescopic rod, a card block, a limit groove, a pressure plate, an anti-skid pad, a top rod, a hinged seat, a card frame and a first spring. The air duct is on the top of the supporting plate. Before moving the supporting plate, the two groups of telescopic rods are inserted into the two groups of installation boxes in sequence, and then the pressure plate is pressed down with force. The pressure plate drives the two telescopic rods, and the telescopic rods drive the card block. The inclined surface of the card block squeezes the card frame, and the inclined surface of the card frame buckle fits with the inclined surface of the card block. When the two inclined surfaces are out of contact, the first spring squeezes the card frame so that the card frame buckle is stuck on the card block. When the anti-skid pad at the bottom of the pressure plate fits with the top of the air duct, the pressure plate can be stopped to limit the air duct, which can prevent the air duct from being displaced or slipping when the supporting plate is moved.
