Embodiment Construction
[0023] Such as figure 1 As shown, the present invention discloses a maintenance bracket for a large axial flow fan. 7. Double-pipe fixed sleeve 13, the swivel frame 1 includes two lower poles 2, two upper poles 3, one main pole 4 and one diagonal pole 8, the two lower poles 2, Two upper struts 3 and an end of a main vertical rod 4 are rotatably connected on a hinge plate 12 . Like this, two lower struts 2, two upper struts 3 and a main vertical strut 4 in every set of swivel frame 1 all can freely rotate around the hinge plate 12.
[0024] The lower support rod 2, the upper support rod 3, the main vertical rod 4, the main horizontal rod 5, the auxiliary horizontal rod 6 and the diagonal support rod 8 can be truncated by standard circular steel pipes, and the flange fixing sleeve 7, double The pipe fixing sleeve 13 can be a standard steel pipe joint matched with this standard circular steel pipe. Specifically, the flange fixing sleeve 7 can be used to fix a circular steel pi...

The invention discloses a large axial flow fan maintenance support, comprising two rotating frames, one main cross bar, one secondary cross bar and a plurality of flange fixing covers and double-barrelled fixing covers, wherein each rotating frame comprises two lower struts, two upper struts, one main upright and one brace, one end of each of the two lower struts, one end of each of the two upper struts and one end of the main upright are rotatably connected onto a capstan. The application method of the large axial flow fan maintenance support comprises the following steps of: firstly, carrying out initial mounting; secondly, hoisting first half of an air duct; thirdly, removing the first half of the air duct; and fourthly, hoisting a motor. By adopting the large axial flow fan maintenance support and application method thereof in the invention, the first half of the air duct and the motor which are heavier can be dismounted and moved away easily by virtue of simple assembling in a narrow maintenance space, and labour is saved, thus being convenient for maintenance personnel to maintain the large axial flow fan. Meanwhile, by adopting the large axial flow fan maintenance support and application method thereof in the invention, labour is saved, and operation safety is higher.
Description
technical field [0001] The invention relates to a fan maintenance equipment, in particular to a simple maintenance bracket and a usage method thereof for maintenance of a large axial flow fan with split-type fan cylinders. Background technique [0002] With the development of cities and transportation, more and more subways and tunnels are being built. In longer tunnels, fans are required for forced air supply and exhaust. Usually, a large axial flow fan is used in subways and tunnels, such as subway fans and tunnel fans, and some of them weigh up to one ton. For the convenience of repairing the impeller or motor or removing the impeller and motor, the air duct is usually divided into a combination of the upper half air duct and the lower half air duct. When the fan needs to be removed for maintenance, the impeller or motor in the air duct , you need to remove the connection between the upper half of the air cylinder and the lower half of the air cylinder, and then remove t...
