Description

Technical Field

[0001] The present invention relates to the technical field of air duct installation, and more specifically, to an air duct installation hanger and an installation method. Background Art

[0002] Air ducts are pipes used for air delivery and distribution. Air ducts are usually located on the upper part of the house, at a relatively high distance from the ground. During the installation of air ducts, the roof, floor and other horizontal building planes that have a supporting function are usually used as the hanging surface, and the air ducts are suspended below the hanging surface using a suspension mechanism.

[0003] The installation hanger in the prior art that is closest to the present application is the one with announcement number: CN105217506B, which discloses a duct installation hanger and an installation method. The hanger includes a bracket, a guide rod, a pulley, a hanger, a hanger clamp and an anti-fall clamp. The bracket is linked to the pulley through a rope, the guide rod vertically passes through a through hole on the bracket and is connected to the tail of the hanger, the head of the hanger is connected to the hanger clamp, the pulley is connected to the hanger clamp through a hook, and the anti-fall clamp is arranged under the hanger clamp and is connected to the hanger to prevent the hanger clamp from sliding down.

[0004] Existing installation hoists still require multiple people to synchronously operate multiple rope pulley structures to synchronously lift the air duct. It is not convenient for multiple people to collaborate to keep the air duct level during the lifting of the air duct, and subsequent position adjustment also requires multiple people to collaborate, which is time-consuming and labor-intensive, and has low installation efficiency.

The conical ring 9 is threadedly connected to the conical groove in the mounting block 2 and the suspension rod 1 respectively.

[0014] A method for installing an air duct using an air duct installation hanger, characterized in that:

[0015] Step 1: The mounting block 2 and the mounting box 3 are lifted as a whole to the position of the suspension rod 1 fixedly installed on the roof, and the distance between the two mounting blocks 2 is adjusted according to the width of the position of the suspension rod 1, so that the conical groove on the mounting block 2 is sleeved on the suspension rod 1; Step 2: Push the mounting block 2 upward to move the mounting block 2 to the upper part of the suspension rod 1, and then combine and fit the two conical rings 9 to the suspension rod 1, lower the height of the mounting block 2, and then make the mounting block 2 sleeved on the conical ring 9, and then under the action of gravity, the inclined surface of the conical ring 9 causes the conical ring 9 to be close to the suspension rod 1, and the position of the mounting block 2 is fixed under the action of the thread of the suspension rod 1 and the thread inside the conical ring 9; lower the lower end of the traction rope to close to the ground, and at the same time, fix the clamping frame 11 to both sides of the mounting frame 5 by bolts, and then connect the traction rope to the lifting ring 7;

[0016] Step 4: After the traction rope is connected in step 3, the winding motor 41 drives the mounting frame 5 to lift so that the mounting frame 5 is off the ground, and then the air duct is placed on the mounting frame 5. After the placement is completed, the winding motor 41 drives the winding roller 43 to rotate, and the rotation of the winding roller 43 indirectly drives the lifting ring 7 and then drives the mounting frame 5 to further drive the air duct body 12 to rise. When the air duct body 12 rises to the position of the suspension rod 1, the rise is completed but when the air duct is not in a horizontal state and still needs to be adjusted, the reduction motor 42 drives the correction frame 45 to rotate, and the correction frame 45 rotates to drive the correction roller 44 on one side to rise in height, and then the correction roller 44 on one side pulls the traction rope upward, thereby adjusting the angle of the air duct body 12. After the adjustment is completed, the position of the mounting frame 5 is locked by bolts to complete the installation.

[0017] Furthermore, the winding motor 41 drives the mounting frame 5 to lift a distance less than 10 cm.

[0018] Furthermore, step four also includes that after the traction rope is connected in step three, the winding motor 41 drives the mounting frame 5 to lift so that the mounting frame 5 is off the ground, and then the air duct is placed on the mounting frame 5. After the placement is completed, the winding motor 41 drives the winding roller 43 to rotate, and the rotation of the winding roller 43 indirectly drives the lifting ring 7 and then drives the mounting frame 5 to further drive the air duct body 12 to rise. When the air duct body 12 rises to the position of the suspension rod 1, the rise is completed but when the angle sensor detects that the air duct is not in a horizontal state and still needs to be adjusted, the reduction motor 42 drives the correction frame 45 to rotate, and the correction frame 45 rotates to drive the correction roller 44 on one side to rise in height, and then the correction roller 44 on one side pulls the traction rope upward, thereby adjusting the angle of the air duct body 12, and the adjustment is completed through the angle data of the angle sensor, and the installation is completed by locking the mounting frame 5 position with bolts.

[0019] Beneficial effects of the present invention:

[0020] (1) High degree of automation: Through the coordinated use of the winding motor 41 and the reduction motor 42, the automatic lifting and horizontal adjustment of the air duct are realized, which greatly reduces the need for manual operation and improves the automation level of the installation process.

[0021] (2) Easy operation: The mounting block separation structure and conical ring allow the equipment to be quickly fixed to the boom, and the air duct can be stably lifted through a simple mechanical structure, simplifying the installation process.

[0022] (3) Safe and reliable: The conical ring 9 is respectively connected to the conical groove in the mounting block 2 and the threaded connection of the suspension rod 1 to ensure the stability of the mounting block and prevent the risk of the duct falling off due to excessive weight. At the same time, the correction mechanism can ensure that the duct remains horizontal during the lifting process, avoiding safety hazards caused by tilting.

[0023] (4) Easy to adjust: The deceleration motor 42 drives the deviation correction roller 44 to adjust the angle of the air duct, so that even when the air duct has been lifted to a certain height, its posture can be easily adjusted to ensure installation accuracy.

[0024] (5) Cost-effectiveness: This solution not only reduces labor costs, but also reduces material loss caused by operational errors, thereby improving the overall economic benefits of the duct installation project.

[0025] (6) Strong adaptability: The air duct installation hanger provided by the present invention can adjust the distance between the installation blocks according to different air duct sizes and installation environments, and has high flexibility and wide applicability.
