Description

Technical Field

[0001] This utility model relates to the field of duct installation technology, and in particular to a cable tray for installing duct bends. Background Technology

[0002] Cable trays are a type of support device that can be built independently. When installed at the bottom of a bridge, cable trays can be used to install pipelines, improving the convenience of pipeline installation. With the continuous development of technology, the functions of cable trays are becoming more and more comprehensive.

[0003] With the development of HVAC technology, central heating or cooling systems are now being used in more and more places. Ducted central systems are an indispensable structure for heating and cooling systems. However, at the floor connection points, the ducts have height differences, making it inconvenient to use ordinary cable trays for hoisting. Ordinary cable trays do not have good fixing points, which makes hoisting difficult. Utility Model Content

[0004] The purpose of this invention is to provide a cable tray for installation at bends in ductwork, thereby solving the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A cable tray for installing at duct bends includes a fixing plate, a first connecting rod, a second connecting rod, a third connecting rod, and a fourth connecting rod. One end of each of the first, second, third, and fourth connecting rods is fixedly connected to the four bottom corners of the fixing plate. The other end of each of the first, second, third, and fourth connecting rods is threaded. The bottom of each of the first, second, third, and fourth connecting rods is fixedly installed with the same duct. Multiple fixing frames are equally spaced along the length of the duct and are fixedly connected to the duct. Screws are fixedly installed on both the front and rear sides of each fixing frame, and connecting rings are screwed onto the screws.

[0007] By adopting the above technical solution, the fixed frame is first fixedly installed on the duct, and then the connecting ring is screwed onto the screw rod. Nuts are screwed onto the screw rod at both ends of the connecting ring. The position of the connecting ring is restricted by the nuts on both sides. Then, through holes are opened on the top of the left and right sides of the connecting ring to insert the first, second, third, and fourth connecting rods. Two nuts are screwed onto each of the first, second, third, and fourth connecting rods to restrict the position of the connecting ring. The duct is hoisted by pulling the fixed frame with the first, second, third, and fourth connecting rods, which can bear the load well. The connecting ring can be leveled so that the first, second, third, and fourth connecting rods can vertically pull the fixed frame.

[0008] In a further embodiment, the outer ring of the connecting ring is axially provided with rectangular pieces.

[0009] By adopting the above technical solution, two rectangular pieces are set, which are ultimately symmetrical from left to right, and a hole is set at the top center of the rectangular piece to avoid the passage of the first link / second link / third link / fourth link.

[0010] In a further embodiment, the top of the fixing plate is provided with a plurality of through holes running vertically through it, and an expansion screw is inserted into each through hole from bottom to top.

[0011] By adopting the above technical solution, expansion screws are used to cooperate with the fixing plate to fix the fixing plate to the top of the wall.

[0012] In a further embodiment, the inner ring of the fixing frame is welded and fixed to the outer wall of the air duct.

[0013] In a further embodiment, a triangular plate is provided at the connection between the rectangular piece and the connecting ring.

[0014] By adopting the above technical solution, the triangular plate is used to strengthen the connection between the rectangular piece and the connecting ring.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. The fixed frame is fixedly installed on the duct, and then the connecting ring is screwed onto the screw rod. Nuts are screwed onto the screw rod at both ends of the connecting ring. The position of the connecting ring is restricted by the nuts on both sides. Then, through holes are made on the top of the left and right sides of the connecting ring to insert the first, second, third, and fourth connecting rods. Two nuts are screwed onto each of the first, second, third, and fourth connecting rods to restrict the position of the connecting ring. The duct is hoisted by pulling the fixed frame through the first, second, third, and fourth connecting rods. This method can bear the load well, and the connecting ring can be leveled so that the first, second, third, and fourth connecting rods can pull the fixed frame vertically.

[0022] Example 1:

[0023] like Figures 1-2 As shown, a cable tray for installing a duct bend includes a fixing plate 1, a first connecting rod 2, a second connecting rod 3, a third connecting rod 4, and a fourth connecting rod 5. One end of each of the first connecting rods 2, 3, 4, and 5 is fixedly connected to the four bottom corners of the fixing plate 1. The other end of each connecting rod is threaded. The bottom of each connecting rod is fixedly installed with the same duct 6. Multiple fixing frames 7 are evenly spaced along the length of the duct 6 and are fixedly connected to the duct 6. Screws are fixedly installed on both the front and rear sides of the fixing frames 7, and connecting rings 8 are screwed onto the screws. Rectangular pieces are evenly arranged axially on the outer ring of the connecting rings 8. The top of the fixing plate 1 has multiple through holes, and expansion screws are inserted into each through hole from bottom to top. The inner ring of the fixing frames 7 is welded to the outer wall of the duct 6. A triangular plate is provided at the connection between the rectangular pieces and the connecting rings 8.

[0024] Specific implementation process: First, the fixed frame is fixedly installed on the duct. Then, the connecting ring is screwed onto the threaded rod. Nuts are screwed onto the threaded rod at both ends of the connecting ring, restricting its position. Through holes are then made on the top left and right sides of the connecting ring, through which the first, second, third, and fourth connecting rods are inserted. Two nuts are screwed onto each of these connecting rods to further restrict their position. The duct is then hoisted by pulling the fixed frame using the first, second, third, and fourth connecting rods. This method provides good load-bearing capacity, and the connecting ring can be leveled, allowing the first, second, third, and fourth connecting rods to pull the fixed frame vertically. A triangular plate is used to connect the bottom of the rectangular piece to the connecting ring, preventing the rectangular piece from bending upwards during pulling.
