DETAILED DESCRIPTION

[0021] The present invention will be further described below in conjunction with the embodiments.

[0022] See also Figure 1-4 The utility model provides a wind energy gearbox planetary gear assembly tool, including an L-shaped beam 1, a clamping device 3 is slidably arranged on the right part of the L-shaped beam 1, a pushing handle 301 is arranged on the clamping device 3, a supporting base 2 is fixedly installed on the bottom of the L-shaped beam 1, a translation device 4 is slidably arranged on the upper part of the L-shaped beam 1, a locking handle 401 is arranged on the translation device 4, a buffer mechanism 5 is arranged on the left part of the L-shaped beam 1, a connecting mechanism 7 is fixedly connected to the top of the translation device 4 and is connected to the buffer mechanism 5, and a limiting mechanism 6 is arranged on the left side of the clamping device 3.

[0023] The cooperation between the buffer mechanism 5 and the connecting mechanism 7 can improve the stability during the hoisting and transportation process, and at the same time protect the hoisted planetary gear to avoid damage during the hoisting process. The stability of the planetary gear fixation is improved by the connecting mechanism 7.

[0024] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that the connecting mechanism 7 includes a connecting plate 701, which is fixedly connected to the top of the translation device 4, and a fixed shaft 702 is rotatably connected to the connecting plate 701, and a connecting block 703 is rotatably connected to the fixed shaft 702, and a lifting ear 704 is fixedly connected to the top of the connecting block 703.

[0025] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth specifically explaining that the buffer mechanism 5 includes a connecting frame 501, which is fixedly connected to the connecting block 703 and arranged on the left side. A slide groove 502 is opened on the connecting frame 501, and a slider 503 is slidably connected to the connecting frame 501 through the slide groove 502. The slider 503 is slidably connected to a slide rod 505 from top to bottom. A turning handle 504 is fixedly connected to the top of the slide rod 505, and a threaded rod 506 is fixedly connected to the bottom end of the slide rod 505. The bottom end of the threaded rod 506 is opened on the L-shaped beam 1 to match it and is threadedly connected. A buffer spring 508 is sleeved on the outer side of the threaded rod 506 between the upper part of the thread groove 507 and the connecting frame 501, and the threaded rod 506 is set to have a length less than the extrusion height of the buffer spring 508.

[0026] The sliding translation device 4 cooperates with the locking handle 401 to facilitate the lifting process to be in a stable state. During lifting, the L-shaped beam 1 rotates through the fixed shaft 702, and the sliding rod 505 slides in the slider 503 by squeezing the buffer spring 508. When it is stable, the turning handle 504 is turned to make the threaded rod 506 move in the thread groove 507, and the slider 503 is limited by the turning handle 504, thereby further improving the stability of the L-shaped beam 1. At the same time, the elastic force of the buffer spring 508 makes it have a buffering property, thereby further improving the stability of the planetary gear lifting process.

[0027] According to the above working process, it can be known that: through the setting of the translation device 4 in cooperation with the clamping device 3, the planetary wheel can be quickly installed and disassembled, thereby improving the assembly efficiency; at the same time, the translation device 4 in cooperation with the connecting mechanism 7 can quickly adjust the stability of the planetary wheel during hoisting, so that it can be transported stably, thereby improving the hoisting stability; in cooperation with the buffer mechanism 5, the protection during transportation is improved.

[0028] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth explaining in detail that the limiting mechanism 6 includes a screw 601, which is threadedly connected to the clamping device 3, and the bottom of the screw 601 is rotatably connected to a mounting plate 602, and the bottom of the mounting plate 602 is fixedly connected to an anti-skid pad 603, which is made of rubber material.

[0029] By rotating the screw rod 601, the screw rod 601 moves in a threaded manner to push the mounting plate 602 to reinforce and lock the upper part of the planetary gear, thereby improving the stability of the planetary gear.

[0030] This scheme has the following working process: when this device is used, the planetary wheel is placed on the upper part of the supporting base 2, and the pressing device 3 is locked to the upper part of the planetary wheel by sliding the pressing device 3 and cooperating with the pushing handle 301. At the same time, by rotating the screw rod 601, the screw rod 601 is threadedly moved to push the mounting plate 602 to reinforce and lock the upper part of the planetary wheel, thereby improving the stability of the planetary wheel. The device is lifted by the lifting ear 704, and then the planetary wheel is transported. Before the formal lifting, the sliding translation device 4 is used in conjunction with the locking handle 401 to facilitate the lifting process to be in a stable state. During the lifting, the L-shaped beam 1 rotates through the fixed shaft 702, and is compressed and slowed down. The impact spring 508 allows the slide bar 505 to slide in the slider 503. When it is stable, the turning handle 504 is turned to allow the threaded rod 506 to move in the threaded groove 507. The turning handle 504 limits the slider 503, thereby further improving the stability of the L-shaped beam 1. At the same time, the elastic force of the buffer spring 508 makes it have buffering properties, further improving the stability of the planetary gear lifting process. When the planetary gear is assembled, the clamping device 3 on the L-shaped beam 1 is loosened by pushing the handle 301, thereby facilitating the sliding of the clamping device 3 to loosen the planetary gear, thereby facilitating the subsequent assembly of the device and improving the practicability of the device.

[0031] In summary: by setting up the translation device 4 in cooperation with the clamping device 3, the planetary wheel can be quickly installed and disassembled, thereby improving the assembly efficiency; at the same time, by using the translation device 4 in cooperation with the connecting mechanism 7, the stability of the planetary wheel during hoisting can be quickly adjusted, so that it can be transported stably, thereby improving the stability of the hoisting; in cooperation with the buffer mechanism 5, the protection during the transportation process can be improved; by using the buffer mechanism 5, a certain buffering protection can be provided to the planetary wheel during the hoisting process, so that it can have a buffering capacity when it is hit, thereby reducing the probability of damage, and further enhancing the stability during the hoisting process.
