Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, specifically to a balanced beam structure, a cooling tower air outlet, and a cooling tower. Background Technology

[0002] As steel structure cooling towers develop towards larger diameters and higher power, the weight, torque, and vibration load of the fan-motor unit at the top of the cooling tower have increased significantly. Existing cooling tower fan balance beams mostly use welded structures of I-beams or channel steel, which have the following shortcomings:

[0003] 1. Difficulties in transportation and on-site installation: The integrally welded coupling / drive shaft protective cover bracket is prone to deformation during long-distance transportation, occupies a large space, and on-site calibration is time-consuming.

[0004] 2. Inconvenient maintenance: The protective cover is welded to the bracket, and the bracket needs to be cut when repairing the coupling or drive shaft, which damages the anti-corrosion layer and increases maintenance costs.

[0005] Therefore, it is necessary to design a balanced beam structure and cooling tower vents and cooling towers that improve structural strength and transportation convenience. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by providing a balanced beam structure, a cooling tower vent, and a cooling tower, thereby solving the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a balance beam structure, characterized in that: it includes a main beam, with a fan base and a motor base respectively provided at both ends along the axial direction of the main beam, and a plurality of support beams provided below the main beam. The upper side of the fan base is used to fix a reducer for the cooling tower fan, and the upper side of the motor base is used to fix a drive motor that outputs power to the reducer. The drive motor and the reducer transmit power through a transmission shaft and a coupling. A detachable coupling protective cover bracket is provided on the side of the main beam corresponding to the coupling near the motor base, and a transmission shaft protective cover bracket is provided on the main beam between the fan base and the coupling protective cover bracket.

[0008] This utility model further illustrates that two longitudinal fixing plates and two transverse fixing plates are vertically arranged on the lower side of the fan base. The two longitudinal fixing plates and the two transverse fixing plates are perpendicular to each other in the horizontal direction and are integrally arranged.

[0009] The present invention further explains that three longitudinal fixing plates and two transverse fixing plates are vertically arranged on the lower side of the motor base. The three longitudinal fixing plates and the two transverse fixing plates are perpendicular to each other in the horizontal direction and are integrally arranged.

[0010] This utility model further explains that each of the two longitudinal fixing plates has a groove on the side away from the fan base that matches the outer diameter of the main beam. The groove cooperates with the main beam so that the two longitudinal fixing plates can be welded and fixed after encircling the main beam. Each of the three longitudinal fixing plates has a groove on the side away from the motor base that matches the outer diameter of the main beam. The groove cooperates with the main beam so that the three longitudinal fixing plates can be welded and fixed after encircling the main beam.

[0011] The present invention further explains that the upper flange of the support beam has a groove three that matches the outer diameter of the main beam. After the main beam is embedded in the groove three, it achieves radial positioning and is welded to the support beam to form an integral whole.

[0012] A cooling tower vent includes a balance beam structure as described above, and also includes a duct, wherein the balance beam structure is mounted on the duct.

[0013] A cooling tower includes a cooling tower vent and a tower body, wherein the vent is installed on the top of the tower body.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: In this utility model, the main beam adopts a closed section of threaded steel pipe, which is combined with a trapezoidal section longitudinal fixing plate and welded together to form a "pipe-plate" composite anti-torsion structure. Compared with the traditional I-beam, the torsional stiffness is significantly improved, the torsional angle caused by the motor torque is effectively suppressed, and the coaxiality of the reducer and the motor axis is maintained.

[0015] The coupling protective cover bracket is bolted and can be disassembled before leaving the factory. It can be separated from the main beam during transportation to avoid deformation of the bracket due to long-distance bumps. On-site installation can be completed simply by tightening the bolts, shortening the time spent working at height. The detachable bracket design means that the coupling or drive shaft can be removed without destructive removal during maintenance. Simply loosen the bolts to remove the protective cover, avoiding repeated cutting and welding, extending the life of the anti-corrosion layer and reducing maintenance costs.

Each of the three longitudinal fixing plates 7 has a groove 8 on the side away from the motor base 3 that matches the outer diameter of the main beam 1. The groove 8 cooperates with the main beam 1 so that the three longitudinal fixing plates 7 can wrap around the main beam 1 and be welded and fixed.

[0033] Two horizontal fixing plates 9 are vertically installed on the lower side of the motor base 3. The two horizontal fixing plates 9 are symmetrically arranged relative to the central axis of the main beam 1.

The other end of the two transverse fixing plates 9 passes through the two longitudinal fixing plates 7 on the side close to the center of the main beam 1 and is integrally fixedly connected to them. The motor base 3 is fixedly connected to the main beam 1 through the longitudinal fixing plates 7 and the transverse fixing plates 9.

[0035] Several support beams 10 are provided below the main beam 1. The support beams 10 are H-shaped steel structures and are arranged horizontally and perpendicularly to the main beam 1.

[0036] The upper flanges of several support beams 10 are provided with grooves 311 that match the outer diameter of the main beam 1. After the main beam 1 is embedded in the grooves 311, it achieves radial limitation and is welded to the support beams 10 to form an integral whole, further improving the structural stability.

[0037] A coupling protective cover bracket is provided on the main beam 1 at the position of the coupling near the motor base 3. The coupling protective cover bracket includes two uprights 12, which are vertically arranged relative to the main beam 1 in the vertical direction. The two uprights 12 are symmetrically arranged relative to the central axis of the main beam 1.

[0038] The support frame 12 has two threaded holes 13 arranged vertically. The main beam 1 has a threaded hole 14 corresponding to the threaded holes 13 of the support frame 12. The threaded holes 13 and 14 are matched and can be quickly disassembled and assembled by bolts.

[0039] A connecting frame 15 is horizontally installed on the upright frame 12, and the connecting frame 15 is vertically installed relative to the main beam 1 in the horizontal direction.

[0040] Support frames 16 are fixedly connected to the upper sides of both ends of the connecting frame 15 along the length direction. The support frames 16 are set perpendicular to the connecting frame 15 in the horizontal direction.

[0041] Two threaded holes 17 are provided on each of the two support frames 16. The two threaded holes 17 are arranged along the length of the support frame 16. The two threaded holes 17 correspond to the positions of the threaded holes on the coupling protective cover, so that the coupling protective cover is fixed to the coupling protective cover bracket by bolts.

[0042] A drive shaft protective cover bracket is installed at the position of the main beam 1 between the fan base 2 and the coupling protective cover bracket.

[0043] The drive shaft protective cover bracket includes four fixed brackets 18 arranged in a rectangular array, and the fixed brackets 18 are angle steel.

[0044] Each mounting bracket 18 has two threaded holes 19, which are arranged vertically.
