Description

Technical Field

[0001] The utility model relates to the technical field of pipeline installation, in particular to a ventilation pipeline for air purification which is easy to install. Background Art

[0002] Ventilation ducts are metal or composite ducts used in ventilation and air conditioning engineering for industrial and civil buildings. They are a kind of infrastructure for air circulation and purification and reducing the concentration of harmful gases. The installation of ventilation ducts can effectively enhance air circulation in buildings and reduce the concentration of harmful gases.

[0003] The ventilation duct is made of multiple sections of pipes. When installing the ventilation duct, the construction workers need to drill two parallel sets of installation holes in the ceiling of the installation location, and use two sets of expansion hangers to insert into the installation holes for fixing. When installing the ventilation duct, in order to avoid the small gap between the keel support and the ceiling that makes it inconvenient to install the ventilation duct, the ventilation duct needs to be placed between the two sets of hangers first, and then the keel is fixed at the lower end of the hanger so that the keel supports the ventilation duct. This requires a lot of manpower for lifting, which makes the installation of the ventilation duct extremely inconvenient. At the same time, in order to avoid the ventilation duct from falling off from the supported keel, the construction workers need to use connectors and bolts to connect the ventilation duct to the keel. There are many parts required, and the construction workers need to use tools to install them one by one. When repairing and replacing the ventilation duct, they need to use tools to disassemble them one by one, which is time-consuming and labor-intensive, and reduces work efficiency.

The bearing plates are provided in two groups, and the upper surfaces of the two groups of bearing plates are provided with the duct body. The upper surfaces of both ends of each group of bearing plates are respectively provided with a group of adjustment structures. The adjustment structure comprises a connecting pipe, a sleeve and a threaded rod. The upper end of the connecting pipe is sleeved with a sleeve, and the inside of the sleeve is provided with a threaded rod. The side surfaces of both ends of each group of bearing plates are respectively provided with a group of fixing structures. The fixing structure comprises a mounting plate, an ear plate, a screw and a clamping plate. The upper surface of one end of the mounting plate is fixedly connected with an ear plate, and the upper side surface of the ear plate is provided with a threaded hole, and the inside of the threaded hole is provided with a screw, and one end of the screw is provided with a clamping plate.

[0006] Preferably, the lower end of the connecting tube is fixedly connected to the upper surface of the bearing plate, the upper end of the connecting tube is fixedly connected to the connecting plate, and the upper surface of the connecting plate is provided with a threaded hole.

[0007] Preferably, the lower end of the threaded rod is arranged inside the threaded hole on the upper surface of the connecting plate, and a servo synchronous motor is arranged at the upper end of the threaded rod. One side of the servo synchronous motor is fixedly connected to the inner wall of the sleeve, and the power output end of the servo synchronous motor is fixedly connected to the upper end of the threaded rod.

[0008] Preferably, a group of fixing plates are fixedly connected to both sides of the upper end of the sleeve, and a fixing hole is formed on the upper surface of each group of fixing plates.

[0009] Preferably, one side of the mounting plate is fixedly connected to the side surface of the supporting plate, and two groups of sliding grooves are provided on the upper surface of the mounting plate, and a group of sliding blocks are slidably arranged inside the two groups of sliding grooves on the upper surface of the mounting plate, and through holes are provided on the side surfaces of the two groups of sliding blocks, and a group of sliding rods are respectively arranged inside the through holes on the side surfaces of the two groups of sliding blocks, and the two ends of the two groups of sliding rods are respectively fixedly connected to the inner walls on both sides of the two groups of sliding grooves on the upper surface of the mounting plate.

[0010] Preferably, one end of the screw is fixedly connected to a rotating wheel, the end of the screw close to the clamping plate is rotatably connected to one side of the clamping plate, the side of the clamping plate away from the screw is attached to the outer surface of the pipe body, and the lower surface of the clamping plate is fixedly connected to the upper surfaces of the two sets of sliding blocks.

[0011] Compared with the related art, the ventilation duct for air purification provided by the utility model which is easy to install has the following beneficial effects:

[0012] By providing a bearing plate and an adjusting structure, an operator first drills an installation hole on the ceiling where the installation is required, and places the bearing plate through the upper surface fixing holes of the fixing plates on both sides of the upper end of the sleeve in the upper surface adjusting structure at both ends corresponding to the ceiling installation holes, and screws the expansion bolts into the fixing plates and the inner walls of the ceiling installation holes to complete the installation of the bearing plate. When the operator installs the pipeline body, the operator starts the servo synchronous motor, and the rotation of the power output end of the servo synchronous motor drives the threaded rod to rotate. When the threaded rod rotates, it is threadedly connected with the threaded hole on the upper surface of the connecting plate, so that the connecting pipe gradually extends out from the inside of the sleeve, so that the space between the bearing plate and the ceiling becomes larger, which is convenient for the operator to place the pipeline body on the upper surface of the bearing plate. When the pipeline body is fixed, the operator controls the power output end of the servo synchronous motor to reverse, so that the bearing plate rises and drives the pipeline body to rise to a suitable position, so that the two groups of pipeline bodies are in a suitable connection position, and the two groups of pipeline bodies can be connected and spliced, which effectively improves the convenience of ventilation duct installation.

[0013] By setting up a fixed structure, when the pipe body is placed on the upper surface of the supporting plate, the operator holds and turns the wheel. When the wheel rotates, it drives the screw to rotate inside the threaded hole on the upper side surface of the ear plate. When the screw rotates, it rotates together with one side of the clamping plate, and at the same time pushes the clamping plate through the through hole on the side surface of the sliding block on the lower surface to slide on the outer surface of the sliding rod and slide along the inner groove on the upper surface of the installation plate, so that the clamping plate fits the outer surface of the pipe body, completing the clamping and fixing of the pipe body, reducing the time for construction personnel to disassemble and install the ventilation duct, and effectively improving work efficiency.

The upper surface of the connecting plate 12 is provided with threaded holes, and the connecting plate 12 is convenient for connecting the connecting tube 4 .

[0022] Among them, the lower end of the threaded rod 6 is arranged inside the threaded hole on the upper surface of the connecting plate 12, the threaded rod 6 is threadedly connected to the threaded hole on the upper surface of the connecting plate 12, and the lower end of the threaded rod 6 is fixedly connected to a limiting plate to prevent the threaded rod 6 from falling off from the connecting plate 12.

The servo synchronous motor 13 is electrically connected to an external power supply, and the servo synchronous motor 13 is started. The power output end of the servo synchronous motor 13 rotates to drive the threaded rod 6 to rotate. When the threaded rod 6 rotates, it is threadedly connected to the threaded hole on the upper surface of the connecting plate 12, so that the connecting pipe 4 gradually extends from the inside of the sleeve 5, so that the space between the bearing plate 1 and the ceiling becomes larger, which is convenient for the operator to place the pipeline body 2 on the upper surface of the bearing plate 1.

[0023] Among them, a group of fixing plates 14 are fixedly connected to both sides of the upper end of the sleeve 5, and a fixing hole is opened on the upper surface of each group of fixing plates 14. The fixing plates 14 are convenient for connecting the sleeve 5 and the ceiling at the installation location. First, a mounting hole is drilled in the ceiling at the location where the installation is required, and the supporting plate 1 is adjusted through the upper surface of the two ends of the structure 3 so that the fixing holes on the upper surfaces of the fixing plates 14 on both sides of the upper end of the sleeve 5 correspond to the ceiling mounting holes, and the expansion bolts are screwed into the fixing plates 14 and the inner walls of the ceiling mounting holes to complete the installation of the supporting plate 1.

When the operator is installing the pipeline body 2, the operator starts the servo synchronous motor 13, and the rotation of the power output end of the servo synchronous motor 13 drives the threaded rod 6 to rotate. When the threaded rod 6 rotates, it is threadedly connected with the threaded hole on the upper surface of the connecting plate 12, so that the connecting pipe 4 gradually extends out from the inside of the sleeve 5, so that the space between the bearing plate 1 and the ceiling becomes larger, which is convenient for the operator to place the pipeline body 2 on the upper surface of the bearing plate 1. When the pipeline body 2 After being placed on the upper surface of the supporting plate 1, the operator holds and rotates the rotating wheel 17.

When the pipeline body 2 is fixed, the operator controls the power output end of the servo synchronous motor 13 to reverse, so that the supporting plate 1 rises and drives the pipeline body 2 to rise to a suitable position, so that the two groups of pipeline bodies 2 are in a suitable connection position, and the two groups of pipeline bodies 2 can be connected and spliced.
