Embodiment 1

[0035] Such as Figure 1 to Figure 6 As shown, a device for replacing the yaw brake clip of the fan and the external cooling fan of the generator in this embodiment includes a base 2 and a telescopic tube 3, and the upper part of the top telescopic tube 301 at the top of the telescopic tube 3 is provided with a horizontally penetrating fixed The hole 302, the top telescopic tube 301 is provided with a support mechanism, the support mechanism is a locking rod 4, the locking rod 4 passes through the fixing hole 302 and is vertically distributed with the top telescopic tube 301, and the two ends of the locking rod 4 are symmetrical along the top telescopic tube 301 Distributed and the upper end surface of the locking rod 4 is a plane, which can increase the support plane area. It should be noted that the expansion and contraction design of the expansion tube 3 can be realized by various conventional designs, which will not be described one by one here. Specifically, in this embod...

Embodiment 2

[0037] A device for replacing the fan yaw brake clip and the generator external cooling fan in this embodiment is basically the same as in Embodiment 1, except that the supporting mechanism in this embodiment is a conversion joint 6, such as image 3 As shown, the top of the conversion joint 6 is provided with a support platform 7, the bottom of the conversion joint 6 is provided with a connecting plate 8, and the bottom of the connecting plate 8 is connected to the top telescopic tube 301 through the connecting rod 5, specifically as Figure 4As shown, the bottom of the connecting rod 5 extends into the top telescopic tube 301, and the bottom of the connecting rod 5 is provided with an installation hole. It should be noted that the connecting rod 5 and the top telescopic tube 301 can also be fixedly connected by screw fit, and multiple reinforcing ribs can be arranged on both sides of the connecting rod 5 to support the connecting plate 8 together.

[0038] Such as Figure 5...

Embodiment 3

[0041] A device for replacing the fan yaw brake clip and the external cooling fan of the generator in this embodiment is basically the same as that in Embodiment 2. Furthermore, in this embodiment, the middle part of the connecting shaft 603 is also provided with a middle support rod 607, such as Figure 5 with Image 6 As shown, the middle platform 703 is arranged on the top of the middle strut 607, and the middle strut 607 is a telescopic rod (a variety of telescopic structures such as multi-section threaded rod telescopic cooperation can be provided, which will not be described in detail here). In actual use, when the X-shaped openings of the first joint 601 and the second joint 602 are small, the middle strut 607 can be set to a contracted state, the first platform 701 and the second platform 702 are connected, and the middle platform 703 is located on the first platform 701 and the second platform 702, when the X-shaped openings of the first joint 601 and the second joint...

Abstract

The invention discloses a device for replacing a fan yawing brake clip and an electric generator external cooling fan, and belongs to the field of wind power generation. The device comprises a base and a telescopic pipe, a horizontal through fixing hole is formed in the upper portion of a top telescopic pipe at the top of the telescopic pipe, a supporting mechanism is arranged at the top of the top telescopic pipe and is a locking lever or crossover coupling, the locking lever penetrates the fixing hole and is perpendicular to the top telescopic pipe, a supporting table is arranged at the topof the crossover coupling, a connecting plate is arranged at the bottom of the crossover coupling, and the bottom of the connecting plate is connected with the top telescopic pipe through a connectingrod. The device overcomes the shortcomings of large weight, time and energy waste of detachment and replacement of a fan yawing brake clip and an electric generator external cooling fan in the priorart, the fan yawing brake clip and the electric generator external cooling fan can be effectively supported and conveniently detached by operators, time and energy are saved, and operating efficiencyis effectively improved.

Description

technical field [0001] The invention relates to the technical field of wind power generation, and more specifically relates to a device for replacing the yaw brake clamp of a fan and the external cooling fan of a generator. Background technique [0002] The yaw system of the wind turbine is a follow-up system. The wind direction instrument transmits the collected signal to the PLC I / O board of the cabin cabinet, calculates the 10-minute average wind direction, compares it with the absolute value encoder of the yaw angle, and outputs the command Drive four yaw motors, adjust the nose in the direction facing the wind, and record the current adjusted angle, after the adjustment, the motors stop and start the yaw brake. The brake of the yaw system of the existing wind power generating set mainly relies on hydraulic brake clips to brake the brake disc. In addition, when the wind turbine yaws automatically, it often carries a certain amount of pressure to ensure the smooth operat...
