Description

Technical Field

[0001] The utility model belongs to the technical field of main shaft brake discs of wind generator sets, and particularly relates to a device for quickly positioning and installing main shaft brake discs of wind generator sets. Background Art

[0002] At present, more than half of the mainstream wind turbines on the market adopt a horizontal axis doubly fed structure, and doubly fed wind turbines must have a main shaft brake disc installation process. Whether the gap between the main shaft brake disc and the brake pad is uniform after installation will directly affect the braking effect of the unit during safe shutdown, which will further affect the safe operation of the unit. In order to ensure that the gap between the brake disc and the brake pad is uniform, there are strict and precise requirements for the installation size of the brake disc on the output shaft of the gearbox: taking a 1.5MW wind turbine as an example, the distance between the end face of the brake disc and the brake installation platform is required to be 90±1mm, and the end face runout is ≤0.3mm.

[0003] Affected by the different gearbox output shaft structures and brake caliper sizes, the main shaft brake disc will be adjusted, disassembled, and installed many times during the workshop assembly or wind farm maintenance and installation. This not only delays work time and cannot guarantee the accuracy of the installation size, but also may cause certain damage to the brake disc and gearbox output shaft due to multiple disassembly, wasting manpower, material resources, and time costs. Some brake discs with interference fit need to be heated to 90°C, and the installation process is slightly longer. The lower temperature leads to insufficient installation clearance for the brake disc, which is easy to get stuck on the gearbox output shaft, causing quality accidents. Utility Model Content

[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0028] like Figure 1 to Figure 4 As shown, the device for rapid positioning and installation of the main shaft brake disc of a wind turbine generator set of this embodiment includes a left tool 1 and a right tool 2. The left tool 1 and the right tool 2 are connected by threads. The left tool 1 has a set screw 3 for locking the left tool 1 and the right tool 2. The left tool 1 is pressed against the installation platform, and the right tool 2 is pressed against the brake disc. The left tool 1 and the right tool 2 of the utility model are connected by threads, and the overall length of the tool can be changed by rotating the threads. The left tool 1 or the right tool 2 is connected with a set screw 3 that penetrates the internal thread, which can lock the relative movement of the threaded connection part to ensure that the overall length of the tool remains unchanged during use.

[0029] For convenient fixing, a magnet base 4 is provided on the left tool 1, and the magnet base 4 is adsorbed on the mounting platform. The utility model adopts the magnet base 4 for fixing, and can realize single-person operation, so as to achieve the purpose of fast installation of the brake disc.

[0030] Specifically, a boss 11 is provided on the side of the left tooling 1 facing the mounting platform, and the magnet base 4 is annular, and the magnet base 4 is sleeved on the boss 11. The magnet base 4 is sleeved on the boss 11 of the left tooling 1 to prevent the magnet base 4 from falling out of the left tooling 1. The left tooling 1 and the magnet base 4 are bonded together by glue, further improving the connection reliability of the magnet base 4 and the left tooling 1.

[0031] Furthermore, a pointer scale for indicating the rotation position is fixed on the right tool 2. The pointer scale can indicate the current screw-in position of the tool to ensure the accuracy of the overall length.

[0032] It should be noted that the end surface of the left tool 1 close to the installation platform and the end surface of the right tool 2 close to the brake disc are both flat, which can ensure the plane runout of the brake disc installation.

[0033] Among them, the thread matching between the left tooling 1 and the right tooling 2 is a triangular thread tooth, the thread lead angle is smaller than the equivalent friction angle, and the threaded connection can form axial self-locking when subjected to axial pressure, ensuring that the thread will not spin and the overall length of the tooling remains unchanged.

[0034] The left tooling 1 and the right tooling 2 are both cylindrical in shape.

[0035] Specifically, a threaded column 21 is provided on the side of the right tooling 2 close to the left tooling 1, and an internal thread is provided on the side of the left tooling 1 close to the right tooling 2. The threaded column 21 of the right tooling 2 cooperates with the internal thread of the left tooling 1, and the set screw 3 penetrates into the internal thread of the left tooling 1.

[0036] Before installing the wind turbine main shaft brake disc, first adjust the overall length of the device to the size required by the process by rotating the threaded parts of the left and right parts of the device, and tighten the set screw 3 after measuring with a vernier caliper. Place the device between the brake disc and the brake caliper mounting platform, one on each side. The magnet base 4 can ensure that the tooling is easily adsorbed on the mounting platform, allowing single-person operation. When installing the main shaft brake disc, wait until the brake disc is against the tooling and then tighten the brake disc fixing bolts. After tightening the bolts, re-measure the distance between the brake disc and the brake mounting platform to see if it meets the process requirements. Loosen the set screw 3 and rotate the threaded part of the tooling to shorten its overall length, and the device can be easily removed from the installation gap.

[0037] The utility model is simple to manufacture, has a reasonable structure and a clever design. The overall length of the tooling is adjusted by threaded connection. When the thread is subjected to axial pressure, it can form an axial self-locking to ensure that the overall length of the tooling remains unchanged, so as to achieve the requirements of rapid and accurate positioning of the brake disc during the installation process. After the brake disc is installed, the overall length of the tooling can be easily shortened by rotating the thread to achieve the purpose of removing the tooling.

[0038] The utility model has strong universality of structure, and can change the overall length of the tooling through threaded connection adjustment to adapt to the installation process requirements of brake discs of different models, and can also compensate for the wear of the tooling due to long-term use.

[0039] The utility model adopts magnet fixing, can realize single-person operation, and achieves the purpose of quickly installing the brake disc.

[0040] The utility model can also be used in other fields such as brake disc installation where precise positioning of spatial dimensions is required.
