Description

Technical Field

[0001] This utility model relates to the field of industrial fan technology, and in particular to a fixing device for a large industrial fan. Background Technology

[0002] A search revealed that application number 202220548920.7 discloses an industrial large fan fixing device, including a mounting plate, a clamping block slidably connected to the lower surface of the mounting plate, a locking block fixedly installed at the top of the clamping block, a locking groove formed on the lower surface of the mounting plate, a fixing plate mounted on one side wall of the clamping block, a fixing bolt rotatably connected to the lower surface of the fixing plate, the fixing bolt penetrating the lower surface of the fixing plate and extending to the upper surface of the fixing plate, and an arc-shaped groove formed on one side wall of the clamping block.

[0003] The industrial large fan fixing device in this patent application uses a combination of a storage slot, a sliding plate, a fixing block, a limit bolt, a mounting bolt, and a connecting block to adjust the length of the fixing device, allowing for the fixing of mounting rods of different lengths. However, during use, because the top of the clamping block is fixedly connected to the mounting plate, as the length of the fixing block located at the bottom of the clamping block extends, the bottom of the fixing block gradually moves away from the top fixing position of the mounting plate, causing its torque to gradually increase. This makes it difficult for the fixing block to maintain a stable clamping effect on the mounting rod. Therefore, we propose an industrial large fan fixing device. Utility Model Content

[0004] The present invention aims to solve the technical problems existing in the prior art and provide a fixing device for industrial large fans.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an industrial large fan fixing device, comprising two equipment mounting plates, two fixing blocks disposed at the bottom of the two equipment mounting plates, and two telescopically adjustable extension fixing blocks disposed at the bottom of the two fixing blocks. Two mounting bolts are provided through the bottom ends of the two extension fixing blocks. Two positioning bolt assemblies are provided at the top of the side walls of the two fixing blocks. Two sets of positioning screw holes are evenly opened on the lower surfaces of the two equipment mounting plates, corresponding to and adapted to the positions of the two positioning bolt assemblies. The two fixing blocks are installed by the internal threads of the two positioning bolt assemblies and the corresponding positioning screw holes. A support mechanism is provided between the lower surfaces of the two equipment mounting plates that are far apart from each other and the bottom of the side walls of the two extension fixing blocks. The support mechanism includes two support slide tubes rotatably connected to the lower surfaces of the two equipment mounting plates that are far apart from each other, and two telescopic slide rods rotatably connected to the bottom of the side walls of the two extension fixing blocks. The ends of the two telescopic slide rods that are far apart from the two extension fixing blocks are slidably connected to the interior of the two support slide tubes. Two fastening bolts that press against the outer walls of the two telescopic slide rods are threadedly connected to the bottom of the outer walls of the two support slide tubes.

[0006] Furthermore, two sets of connecting slots are provided on the lower surface of the two device mounting plates.

[0007] Furthermore, the two sets of connecting slots are slidably connected to two sets of connecting blocks that are fixedly connected to the top walls of the two fixed clamping blocks.

[0008] Furthermore, the top ends of the two supporting slide tubes are rotatably connected to two first rotating brackets in an inverted L shape.

[0009] Furthermore, two first connecting through holes are provided at the middle of the horizontal ends of the two first rotating brackets.

[0010] Furthermore, two first connecting bolts are installed through the two first connecting through holes.

[0011] Furthermore, the top ends of the two first connecting bolts are respectively threaded into the two positioning screw holes located on the outer side.

[0012] Furthermore, the bottom ends of the two telescopic slide rods are rotatably connected to two L-shaped second rotating brackets.

[0016] 1. This industrial large fan fixing device, through the setting of a support mechanism, in use, fixes two equipment mounting plates at designated positions on the roof. The fan mounting rod is fixed in place by fixing clamps and extension fixing blocks. Simultaneously, two second rotating brackets on two telescopic sliding rods are fixed to the side walls of two extension fixing blocks using two mounting bolts. Two first rotating brackets on two support sliding tubes are fixed to the outer lower surface of the two equipment mounting plates using two first connecting bolts and corresponding positioning screw holes. At this point, the two support sliding tubes and two telescopic sliding rods, together with the two equipment mounting plates, two fixing clamps, and two extension fixing blocks, form a three-dimensional structure. The corner support mechanism provides stable support to the bottom of the two extended fixing blocks, improving the overall structural stability of the equipment. When adjusting the length of the two extended fixing blocks according to the length of the fan mounting rod, the two fastening bolts can be loosened to release the position fixation between the two support slide tubes and the two telescopic slide rods. This allows the two telescopic slide rods to adjust their extension and retraction accordingly with the length adjustment of the two extended fixing blocks. Then, the two fastening bolts are tightened to complete the fixed connection between the two support slide tubes and the two telescopic slide rods, maintaining a stable support effect on the bottom of the two extended fixing blocks. The above operation is simple and practical, with a reasonable and compact structure, improving the overall structural stability and practicality of the equipment. Attached Figure Description
