[0045] In order to solve the above problems, in combination with Figures 1-5As shown, the embodiment provides a yaw caliper friction plate replacement auxiliary tool, which comprises a support base 1, a lifting mechanism, a lifting platform 3 and a clamping assembly 4. The lifting mechanism is arranged on the upper end surface of the support base 1, the lifting platform 3 is connected with the lifting end of the lifting mechanism, the end surface of the lifting platform 3 is provided with a mounting hole 31, the yaw caliper is placed on the lifting platform 3 and the bolt part is located at the mounting hole 31, and the clamping assembly 4 is arranged on the upper end surface of the lifting platform 3. The clamping assembly 4 is configured to clamp and fix the yaw caliper.

[0046] By moving the support base 1 to the wind turbine, adjusting the lifting mechanism to gradually rise until the lifting platform 3 supports the yaw caliper, the labor is saved without manual lifting, the bolt part of the yaw caliper can be located at the mounting hole 31 when being supported, which is convenient for the operator to disassemble and replace, the clamping assembly 4 clamps and fixes the yaw caliper, ensures that the relative position of the yaw caliper and the yaw caliper friction plate replacement auxiliary tool remains unchanged, and after the replacement operation is completed, direct installation is performed without manual calibration, which can guarantee the docking accuracy, saves time and labor for the replacement operation of the friction plate.

[0047] Specifically, as shown in Figure 1 and Figure 3 , the support base 1 is arranged in a rectangular shape, in order to facilitate the movement of the support base 1, a plurality of universal wheels 12 are arranged on the bottom of the support base 1, and through the 360° rolling of the universal wheels 12, the yaw caliper friction plate replacement auxiliary tool can be moved to the lower side of the yaw caliper with less labor.

[0048] The four universal wheels 12 are respectively distributed at the four corners of the bottom surface of the support base 1, which has good support stability and is not easy to appear side turning and the like. In other embodiments, the number of universal wheels 12 can also be two, three, five or even more, which is not limited in the embodiment.

[0049] The universal wheel 12 itself has a self-locking mechanism, and since the self-locking mechanism of the universal wheel 12 is prior art, it will not be described further here. When moved to the position, the position of the support base 1 can be fixed through the self-locking mechanism to avoid displacement of the support base 1 during replacement, which has better stability. Preferably, the universal wheel 12 is made of polyurethane material, which has the characteristics of wear resistance and impact resistance, and can guarantee the service life of the universal wheel 12.

[0057] Specifically, the telescopic part comprises a second cylinder 43, a telescopic end of the second cylinder 43 is connected with the first clamping part 41, and the other end of the second cylinder 43 is connected with the second clamping part 42. The distance between the first clamping part 41 and the second clamping part 42 can be adjusted by the telescopic movement of the second cylinder 43, so that the height of the first clamping part 41 can be adjusted according to the size of the yaw clamp, and the universality is good.

[0058] The first clamping part 41 comprises a first clamping jaw 411 and a second clamping jaw 412 for clamping the upper clamp of the yaw clamp, and the second clamping part 42 comprises a third clamping jaw 421 and a fourth clamping jaw 422 for clamping the lower clamp of the yaw clamp. The first clamping jaw 411 is connected with the third clamping jaw 421, and the second clamping jaw 412 is connected with the fourth clamping jaw 422.

Preferably, the driving part is a double-acting cylinder, and two double-acting cylinders are arranged, one end of one of the double-acting cylinders is connected with the first clamping jaw 411, and the other end of the double-acting cylinder is connected with the second clamping jaw 412, and one end of the other double-acting cylinder is connected with the third clamping jaw 421, and the other end of the double-acting cylinder is connected with the fourth clamping jaw 422. The mutual approach or mutual departure of the two can be realized by the telescopic movement of the double-acting cylinders, and the clamping force on the yaw clamp can be reasonably controlled by the moving distance.
