Description

Technical Field

[0001] This utility model relates to the technical field of fan or duct mounting brackets, and specifically to a fan hoisting bracket. Background Technology

[0002] Fan mounting brackets are essential equipment for installing and hoisting fans. They support the fan ducts and allow for adjustments to height and angle. Existing fan mounting brackets are mainly divided into three structural types: fixed, mobile, and modular. For fans installed long-term, mobile and modular brackets are more expensive to manufacture and their functionality is somewhat wasted. Existing fixed fan mounting brackets mainly consist of hangers fixed to the bottom of the floor slab and detachable support rods mounted at the bottom of the hangers. The fan is mounted on top of the support rods. Some brackets also include shock-absorbing hooks on the hangers to improve vibration damping. However, existing brackets cannot support the connection between the duct and the fan. After prolonged use, this connection is prone to detachment, increasing subsequent maintenance costs. Utility Model Content

[0003] The purpose of this utility model is to provide a fan hoisting bracket that can stably hoist and fix the fan, has good shock absorption capabilities, and can also hoist and support the air ducts connected to both sides of the fan, improving the connection stability at the connection point. The bracket has a simple and compact structure and is highly practical.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A fan mounting bracket includes a hook fixedly installed at the bottom of a floor slab, a hanger rod installed at the bottom of the hook, a support beam installed at the bottom of the hanger rod, a fan mounted on the support beam, and the hanger rod including a shock-absorbing hook and an upper connecting rod and a lower connecting rod connected to the upper and lower ends of the shock-absorbing hook; an auxiliary bracket is installed on the upper connecting rod, an auxiliary hanger rod is installed at the cantilever end of the auxiliary bracket, an auxiliary support beam is installed on the auxiliary hanger rod, and a duct is installed on the auxiliary support beam.

[0006] Preferably, an embedded part is pre-embedded in the floor slab, and the bottom of the embedded part is exposed at the bottom of the floor slab; the hanging part is fixedly connected to the bottom of the embedded part.

[0007] Preferably, the embedded part includes a steel plate and a plurality of U-shaped steel bars fixedly disposed on the top of the steel plate, with arc-shaped barbs provided on both sides of the top of the U-shaped steel bars; the bottom of the steel plate is flush with the bottom of the floor slab.

[0008] Preferably, both the upper connecting rod and the lower connecting rod are screw rods, with the top of the upper connecting rod connected to the hanger and the bottom of the lower connecting rod connected to the support beam.

[0009] Preferably, a shock-absorbing seat is provided between the top of the support beam and the fan.

[0010] Preferably, flexible joints are provided at both ends of the fan, and the flexible joints are sealed to the air duct.

[0011] Preferably, an elastic clamping member is also provided on the auxiliary hanger, which presses the air duct onto the auxiliary support beam.

[0012] In this invention, the shock-absorbing hooks and seats provide dual shock absorption for the fan installation, improving its stability and reducing noise generated by fan vibration during operation. The auxiliary brackets, support rods, and auxiliary support beams provide support at the connection between the fan and the duct, enhancing stability and preventing the flexible joints on both sides of the fan from detaching from the duct due to vibration during use, thus reducing subsequent maintenance costs. The elastic clamping element presses the duct onto the auxiliary support beam, further improving the stability of the duct installation. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4The wind turbine mounting bracket shown includes a hanger 1 fixedly installed at the bottom of a floor slab. Specifically, an embedded part 3 is pre-embedded in the floor slab 2, with its bottom exposed at the bottom of the floor slab 2. The embedded part 3 includes a steel plate 30 and multiple U-shaped reinforcing bars 31 fixedly installed on the top of the steel plate 30 by welding. Arc-shaped barbs 32 are integrally provided on both sides of the top of the U-shaped reinforcing bars 31. The bottom of the steel plate 30 is flush with the bottom of the floor slab 2. The steel plate 30 is a Q235 plate with dimensions of 200mm x 200mm x 6mm.
