Description

Technical Field

[0001] This utility model relates to the field of temporary support technology for air ducts, and in particular to a temporary support frame for air ducts used in building installation. Background Technology

[0002] In modern building construction, the installation of ventilation and air conditioning system ducts is a crucial step. Ducts are typically large and heavy, requiring reliable temporary supports during installation to ensure precise positioning, stable connection, and the safety of construction workers.

[0003] There are various existing methods for temporary duct support, commonly including the use of scaffolding, simple wooden or steel supports, and manually adjustable support rods. These traditional methods often have shortcomings in practical applications. For example, using scaffolding to support ducts requires a significant amount of time and manpower for erection and dismantling, and its height adjustment flexibility is limited, making it difficult to precisely match the installation needs of ducts at different heights. While simple wooden or steel supports are inexpensive, their stability and load-bearing capacity are often insufficient, and their low reusability easily leads to material waste.

[0004] Furthermore, some existing support devices have limitations in terms of mobility, ease of leveling, and precise height adjustment. In complex construction sites, the ground may be uneven, requiring precise leveling of the support frame. Simultaneously, the precise connection of ducts places high demands on the support height, necessitating multi-stage, precise lifting capabilities. Some existing devices are structurally bulky, making them inconvenient to move and relocate, or occupying significant space during storage, thus hindering construction.

[0005] Solving the aforementioned technical problems is the challenge facing this utility model. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a reasonably designed, safe, and reliable temporary support frame for building installation ducts, aiming to overcome the deficiencies of existing duct support devices in terms of mobility, ease of leveling, multi-stage precise lifting, and operational efficiency.

The nut is fixedly installed on the vertical slide block.

[0014] Furthermore, a top support groove is provided on the top surface of the top support slide to slide with the top support frame, and a top support guide seat is provided on the top support slide to slide with the vertical guide rod. The top support frame is slidably connected to the interior of the top support slide; the second lifting component is disposed in the top support groove.

[0015] The second lifting assembly includes a linear drive unit disposed in the top support slide groove and used to drive the top support frame to perform lifting and lowering movements. The top support slide is also provided with a locking unit for locking the height of the top support frame.

[0016] Preferably, the top support frame is provided with a plurality of top support hydraulic rods, and the plurality of top support hydraulic rods are connected together to the same top support contact plate that is in contact with the ceiling;

[0017] The linear drive unit is an electric push rod or a cylinder. The fixed end of the electric push rod or the cylinder body of the cylinder is fixedly connected to one end of the top support slide groove. The push rod of the electric push rod or the piston rod of the cylinder is fixedly connected to the top support frame.

The hoisting frame is also provided with a limiting unit for locking the height of the top support frame.

[0020] Furthermore, the support assembly includes two support connecting seats respectively installed on the hoisting slide and cooperating with the secondary lifting assembly. A support platform is provided between the two support connecting seats and is detachably connected to the support connecting seats for supporting the air duct. A preliminary fixing unit is provided on the support platform for performing preliminary clamping and fixing actions for the air duct.

[0021] Preferably, the inner surface of the support platform is provided with anti-slip texture and elastic anti-slip pad, the elastic anti-slip pad being made of rubber material to enhance the friction on the air duct and protect the surface of the air duct.

[0022] Furthermore, the preliminary fixing unit includes L-shaped clamping plates symmetrically arranged on both sides of the support platform. The L-shaped clamping plates are slidably connected to the support platform via adjusting screws. One end of the adjusting screw has a rotating handle, and the other end passes through the support platform and is rotatably connected to the L-shaped clamping plates.

[0025] This invention comprises a first lifting assembly, a second lifting assembly, and a secondary lifting assembly, which are used to control the height adjustment of the sliding base frame, the top support frame, and the supporting assembly, respectively, achieving full coverage from coarse to fine adjustment. This multi-level adjustment mechanism allows operators to precisely control the installation position of the duct according to site conditions, making it particularly suitable for construction scenarios with significant variations in floor height or requiring precise alignment. Each lifting assembly can be driven by a screw, hydraulically, or electrically, depending on actual needs, balancing the flexibility of manual adjustment with the efficiency of automatic control. For example, a screw drive provides higher positioning accuracy, suitable for installation operations with stringent requirements; while hydraulic or electric actuators are more suitable for the rapid lifting and lowering of heavy-duty ducts.

[0026] The mobile component of this invention employs a combination of omnidirectional wheels and directional wheels with brakes, giving the equipment excellent mobility. When a fixed position is required, the wheels can be locked by operating the brake pads or limiting components to prevent accidental slippage. Simultaneously, four independently adjustable support feet, combined with anti-slip rubber pads, allow for precise leveling on uneven ground, ensuring the stability of the equipment during operation.

[0027] The support assembly of this invention includes a detachable support platform and an L-shaped clamping plate, which can be quickly adapted to ducts of different diameters. Its surface is equipped with anti-slip textures and elastic anti-slip pads to effectively prevent the duct from slipping or causing surface damage. Furthermore, by rotating the adjusting screw to move the clamping plate laterally, the duct can be clamped and fixed, further improving the safety and convenience of the installation process.
