Description

[Technical Field]

[0001] This utility model relates to the installation technology of busbar trunking in power systems, and more particularly to an adjustable hanger for busbar trunking installation. [Background Technology]

[0002] In construction engineering, electrical busbars, cable trays, and ventilation ducts are indispensable parts of modern buildings. They often need to be suspended under the ceiling of the building. The hangers used include angle steel, channel steel, and screw rods. These components are important for achieving the suspended installation of electrical busbars, cable trays, and ventilation ducts.

[0003] During installation, the busbar trunking is fixed to the building ceiling with expansion bolts. Then, by selecting appropriate screw holes on the hanging plate or angle steel bracket hanging vertically into the ceiling, bolts are used to secure the upper end of the angle steel bracket that suspends the busbar trunking. However, directly fixing the hanging plate or angle steel bracket to the building ceiling makes it difficult to adjust the height of the busbar trunking during assembly.

[0004] Meanwhile, when encountering non-horizontal building ceilings, the lack of adjustable technology often makes it impossible to ensure that the busbar trunking is placed horizontally, necessitating on-site repair of hangers or angle steel supports, which brings many troubles to the installation of the busbar trunking. [Utility Model Content]

[0005] This utility model provides an adjustable hanger for busbar installation, which can meet the horizontal installation requirements of busbar without on-site repair, regardless of the ceiling tilt.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] An adjustable hanger for installing busbar trunking, for horizontally suspending the busbar trunking under the ceiling of a building, includes a pair of hanging components, two round steel rods and a pair of angle steel crossbars, the two hanging components being supported and installed on the ceiling by expansion bolts;

[0008] The upper ends of the two round steel rods are respectively sleeved and hung on each hanging component;

[0009] Each of the round steel rods is provided with a U-shaped hook at the lower end for supporting and hanging the end of the angle steel crossbar. Correspondingly, each of the angle steel crossbars is provided with two fitting holes for the end of the U-shaped hook to be inserted and rotated 180° for buckle connection.

[0010] Between the two mounting holes, there is also a ring-shaped adjustable bolt, one end of which is fitted into the middle of the U-shaped hook and the other end is locked to the upper side of the angle steel crossbar by an adjusting nut for adjusting the lifting height. The adjusting nut is used to adjust the vertical lifting height of the angle steel crossbar relative to the round steel rod to maintain horizontal hoisting. An adjusting mounting hole that cooperates with the ring-shaped adjustable bolt is provided between the two mounting holes on the angle steel crossbar.

[0011] Preferably, the adjustable annular bolt is also threaded with a locking nut that cooperates with the adjusting nut and is used to lock the angle steel crossbar from the bottom after the height adjustment is completed.

[0012] Preferably, the hanging component adopts a single-hanging "Z"-shaped structure that is sleeved and hung on the upper end of the round steel rod. The top side of the single-hanging "Z"-shaped hanging component is provided with an expansion connection hole that mates with an expansion bolt. The lower side of the single-hanging "Z"-shaped hanging component is provided with two hanging holes for the upper end of the round steel rod to be sleeved and rotated 180° for hanging connection. The upper end of the corresponding round steel rod is provided with a U-shaped hook that mates with the two hanging holes.

[0013] Preferably, the ends of the U-shaped hooks and U-shaped support hooks at the upper and lower ends of the round steel rod are all fitted with anti-detachment pins to prevent them from coming loose.

[0014] Preferably, a flat washer and a spring washer are also installed between the adjustable annular bolt and the upper side of the angle steel crossbar to prevent damage to the adjustment mounting hole.

[0015] Preferably, each of the angle steel crossbars is also provided with two elongated holes for adjusting the installation at both ends of the busbar trough.

[0016] Preferably, the hanging component adopts a double-hanging "π"-shaped structure that is sleeved and hung on the upper end of the round steel rod. The top two sides of the double-hanging "π"-shaped hanging component are respectively provided with expansion connection holes that cooperate with two expansion bolts. The lower middle part of the double-hanging "π"-shaped hanging component is provided with two hanging holes for the upper end of the round steel rod to be sleeved and rotated 180° for hanging connection. The upper end of the corresponding round steel rod is provided with a U-shaped hook that cooperates with the two hanging holes.

[0017] The beneficial effects of this utility model are:

[0018] To address the challenges of adjusting the height of existing busbar trunking during assembly and the inability to ensure horizontal placement when encountering non-level building ceilings, this invention addresses these issues. The lower end of the round steel hanger is equipped with a U-shaped hook supporting an angle steel crossbar. A circular adjustable bolt is fitted into the middle of the U-shaped hook. The upper end of the adjustable bolt is threaded with an adjusting nut, which is locked to the upper side of the angle steel crossbar for adjusting the lifting height.
