Description

Technical Field

[0001] This utility model belongs to the field of HVAC engineering technology, specifically relating to a suspension and fixing device for HVAC pipeline installation. Background Technology

[0002] Heating, ventilation, and air conditioning (HVAC) engineering refers to the systematic engineering of controlling temperature, humidity, air cleanliness, and airflow velocity within a building through technological means. Its core objective is to create a safe, comfortable, and energy-efficient indoor environment, encompassing subsystems such as heating, cooling, fresh air systems, and air purification. Applications include civil buildings, industrial plants, medical facilities, and transportation hubs, involving multiple disciplines such as thermodynamics, fluid mechanics, and automation control. Typical equipment includes boilers, heat pumps, air conditioning units, ventilation ducts, and intelligent control systems. Efficient operation requires scientific design, precise construction, and intelligent operation and maintenance, while simultaneously meeting modern demands for energy conservation, environmental protection, and sustainable development.

[0003] Pipe installation is a crucial step in HVAC engineering, and suspending pipes from the ceiling is a common installation method. To avoid the impact of vibration and swaying on the pipes, a pipe installation suspension and fixing device (publication number CN222650841U) for HVAC engineering is proposed. This technical solution uses a flexible connection method to effectively buffer against temperature changes or external impacts, thereby preventing pipe deformation or breakage. However, the flexible connection of this technical solution can only rotate along the direction of the pipe, which is too unidirectional and cannot completely avoid external impacts, still leading to pipe deformation or breakage. Furthermore, this technical solution has a relatively fixed pipe fixing position; if the pipe's direction deviates from the design position, it can only be reinstalled, not adapted for different locations. Utility Model Content

[0018] As a preferred embodiment, the track seat structure further includes: a track slider 8, two track locking bolts 9, a slide extension rod 10, and a pipe mounting plate 11; the track slider 8 is movably installed inside the adjusting track 7, and the track slider 8 is fixed inside the adjusting track 7 by the two track locking bolts 9; the slide extension rod 10 is installed on the lower wall of the track slider 8; the pipe mounting plate 11 is installed on the lower wall of the slide extension rod 10; and two mounting holes are provided on the upper wall of the pipe mounting plate 11.

[0019] As a preferred embodiment, the pipe lifting frame structure further includes: a lifting bend 12, two lifting nuts 13, and two lifting springs 14; the two ends of the lifting bend 12 are respectively inserted into the two mounting holes of the pipe mounting plate 11, the two lifting nuts 13 are respectively installed at the tail of the lifting bend 12 by threads, and the two lifting springs 14 are movably installed between the pipe mounting plate 11 and the lifting nuts 13.

[0021] As a preferred option, the upper wall of the fixed base 1 is provided with four mounting holes.

[0022] Working principle:

[0023] I. Installation before use: The operator first drills four mounting holes at the installation location. Then, the operator installs the fixed base 1 in the designated position using expansion bolts. Next, the operator adjusts the position of the length adjusting rod 5 inside the length adjusting main pipe 3 and fixes it inside the length adjusting main pipe 3 using bolts and nuts. At this point, the vertical height of the hoisted pipe is determined. Then, the operator rotates the adjusting rail 7 using the rotating seat 6 according to the pipe's installation direction, ensuring the direction of the adjusting rail 7 aligns with the pipe's direction. The operator inserts the hoisting bend 12 from bottom to top, ensuring the lower wall of the hoisting bend 12 contacts the lower wall of the pipe, inserting the hoisting bend 12 into the two mounting holes of the pipe mounting plate 11. Simultaneously, two hoisting springs 14 are inserted into the tail end of the hoisting bend 12. Two rail locking bolts 9 are threadedly installed at the tail end of the hoisting bend 12, and washers are installed at both ends of the two hoisting springs 14. At this point, the pipe is fixed to the hoisting bend 12. The position of the pipe mounting plate 11 can be adjusted according to the specific installation situation. The operator adjusts the relative position of the track slider 8 inside the adjustment track 7 by adjusting the track slider 8, and fixes the relative position of the track slider 8 and the adjustment track 7 by two track locking bolts 9.

[0024] II. Vibration damping during pipeline installation: When vertical vibration occurs, the vibration is transmitted to the pipeline mounting plate 11. Since the lifting bend 12 is movably installed in the mounting holes of the pipeline mounting plate 11, the vibration is not directly transmitted to the lifting bend 12. Instead, it is buffered by two lifting springs 14, thus preventing vibration of the pipeline directly in contact with the lifting bend 12 and ensuring the stability of the pipeline. When swaying occurs, the fixed base 1 does not transmit the swaying directly downwards. Instead, it is flexibly connected by the universal joint 2, preventing the swaying from being directly transmitted through the rigid connection. Furthermore, the universal joint 2 can decompose the swaying in any direction into bending in both horizontal and vertical directions. At the same time, the energy of the swaying can be absorbed by the pneumatic support rods 4 installed in four directions between the length adjustment main pipe 3 and the fixed base 1, preventing the swaying energy from acting directly on the pipeline.
