Description

Technical Field

[0001] The utility model relates to the field of simple tooling, in particular to a simple tooling for replacing a yaw caliper of a wind turbine generator set. Background Art

[0002] A wind turbine is a system that converts the kinetic energy of wind into electrical energy. It includes a wind rotor and a generator. The wind rotor consists of blades, a hub, and reinforcements. The yaw caliper is one of the important components in a wind turbine. The yaw caliper has a height difference of nearly 2 meters from the yaw platform, because a wind turbine has at least 6 calipers, and each caliper is relatively heavy, about 150KG, and is fixed by eight screws.

[0003] It is difficult to replace the existing caliper. Since the wind turbine yaw caliper is bulky and located at a high position on the yaw platform, it is not conducive to personnel cooperation during replacement. First, it is difficult to put the old caliper on the yaw platform after removal. Second, it is difficult to get the new caliper to the fixed installation position during installation. Third, personnel cannot effectively stand and cooperate during replacement. With current technology, it seriously affects the replacement efficiency. At the same time, there are great safety hazards during replacement, and the replacement personnel may be injured during replacement. In order to solve the above problems, we propose a simple tooling for replacing the yaw caliper of a wind turbine. Utility Model Content

[0004] The utility model aims to provide a simple tool for replacing a yaw caliper of a wind turbine generator set, which solves the problem that the existing yaw caliper is time-consuming and labor-intensive to replace and is prone to potential safety hazards.

[0005] The above-mentioned technical objective of the utility model is achieved through the following technical scheme: a simple tool for replacing the yaw caliper of a wind turbine generator set, comprising a shell, a fixing frame is provided on the top of the shell, a top plate is welded to the top of the fixing frame through a support rod, a first bidirectional screw is rotatably connected inside the fixing frame, two clamping plates are threadedly connected to the surface of the first bidirectional screw, eight through grooves are opened on the top of the top plate, a second bidirectional screw is rotatably connected inside the shell, a motor is fixedly sleeved on the other end of the second bidirectional screw, a cross brace is provided inside the shell, the top of the cross brace is rotatably connected to two first fixing seats, and the bottom of the cross brace is rotatably connected to two second fixing seats threadedly connected to the second bidirectional screw, the interior of the shell and the bottom of the fixing frame are both bolted with slide rails, and sliders slidably connected to the slide rails are welded to the top of the first fixing seat and the bottom of the second fixing seat.

[0006] By adopting the above technical solution, the caliper can be clamped and fixed to prevent the caliper from shifting and misaligning with the through slot when moving upward or shaking, thereby reducing the adjustment burden on personnel. At the same time, it has a height adjustment function, which is simple and labor-saving to operate, thus reducing the workload of personnel. It is also in line with modern safety concepts and greatly shortens the time cost required for replacement.

[0007] The utility model is further configured as follows: a guide rail is bolted inside the fixing frame, and a guide block slidably connected to the guide rail is welded on the bottom of the clamping plate.

[0008] By adopting the above technical solution, the clamping plate can be limited by setting the guide rail and the guide block to prevent the clamping plate from rotating during the process of moving left and right.

[0009] The utility model is further configured as follows: rubber pads are bolted to opposite sides of the two clamping plates.

[0010] By adopting the above technical solution and providing the rubber pad, the caliper can be protected to prevent the clamping plate from scratching the surface of the caliper when clamping.

[0011] The utility model is further configured as follows: the other end of the first bidirectional screw rod penetrates the outside of the fixing frame and is welded with a turning handle.

[0012] By adopting the above technical solution and setting the turning handle, it is convenient for personnel to rotate the first bidirectional screw.

[0013] The utility model is further configured as follows: a universal wheel is installed at the bottom of the shell, and a brake pad is installed on the surface of the universal wheel.

[0014] By adopting the above technical solution and providing the universal wheels and brake pads, it is convenient for personnel to move the equipment.

[0015] The utility model is further configured as follows: two heat dissipation grooves are arranged on the front side of the shell, and dustproof nets are installed inside the heat dissipation grooves.

[0016] By adopting the above technical solution, the heat dissipation effect inside the shell can be improved through the provision of the heat dissipation groove and the dustproof net, and dust in the air can be prevented from falling into the shell.

[0017] The utility model is further configured as follows: the first bidirectional screw and the clamping plate are both made of stainless steel.

[0018] By adopting the above technical solution, the first bidirectional screw and the clamping plate have the excellent characteristics of high strength, low density and high corrosion resistance.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. The utility model pushes the housing to the designated position first, and then places the caliper on the top of the top plate. After the caliper is placed, the position of the lower mounting hole corresponds to the through slot. Then, the first bidirectional screw is rotated by holding the handle. When the first bidirectional screw rotates, it drives the two clamping plates to move inwards through the cooperation of the guide rail and the guide block. When the clamping plates move inwards, they clamp the caliper, and the caliper can be clamped and fixed, so as to avoid displacement and misalignment of the through slot when the caliper is moved upward or shaken, thereby reducing the adjustment burden of the personnel.

[0021] 2. The utility model starts the motor, and after starting, the motor drives the second bidirectional screw to rotate. When the second bidirectional screw rotates, it drives the two second fixed seats to move inward through the cooperation of the slide rail and the slider. When the second fixed seats move together, the cross braces will be spread open and the fixed frame will move upward. When the fixed frame moves upward, it will drive the upper caliper to move up to the installation position. Finally, the screws are passed through the through slots under the top plate to fix it. It can have a height adjustment function, is simple and labor-saving to operate, reduces the workload of personnel, conforms to modern safety concepts, and greatly shortens the time cost required for replacement.
