Description

Technical Field

[0002] In the maintenance and motor replacement of cooling towers, the connection between the cooling tower's upper cooling fan gearbox and the motor faces numerous challenges. Currently, when the motor needs to be replaced and reinstalled, it is difficult to connect the splice joint on the motor to the coupling inside the gearbox, and the limited installation space makes the operation extremely inconvenient.

[0003] Traditional installation methods rely mainly on the operator's experience to adjust the motor position. This method is not only time-consuming, but also faces difficulties during the compression of the coupling elastomer. The installation process is also prone to misalignment, affecting the installation quality and efficiency.

The gearbox connecting seat platform is provided with a support platform hole 103. One end of the centering bolt 2 is used to pass through the support platform hole 103 and be fixed to the flange hole of the gearbox body. The centering bolt 2 and the flange hole of the gearbox body are coaxially arranged. The support seat includes a motor support seat platform 303 and a centering plate 4. The top of the motor support seat platform 303 is provided with a first upper recess. The centering plate 4 is used to be placed on the first upper recess so that the center line of the centering plate 4 is collinear with the center line of the centering bolt 2. The top end of the centering plate 4 is used to extend into the flange hole on the motor so that the center line of the flange hole on the motor is collinear with the center line of the flange hole of the gearbox body. The support seat and the connecting seat are slidably connected in the axial direction of the centering bolt 2. The driving component is used to drive the support seat to slide in the axial direction of the centering bolt 2 and maintain the position after sliding. By aligning the centering bolt 2 with the flange hole of the gearbox, a precise reference is provided for the subsequent alignment of the motor and gearbox, ensuring accurate alignment of the centerlines of their flange holes during installation, thus improving installation accuracy and stability. The centering plate 4 precisely guides the motor onto the platform, ensuring that the centerlines of the motor flange hole and the gearbox flange hole are collinear, further improving the accuracy of the motor-gearbox connection and reducing installation errors. The sliding connection between the support and connecting seat, along with the drive mechanism, allows the motor to be flexibly adjusted during installation, while the drive mechanism maintains its position, ensuring stability and enabling the motor and gearbox to connect in the ideal position.

[0027] In a preferred embodiment, the connecting seat further includes a gearbox connecting seat side plate 1. The gearbox connecting seat side plate 1 is vertically fixedly connected to the gearbox connecting seat platform 104 to form an L-shaped structure. A slide groove 101 is provided on the side of the gearbox connecting seat side plate 1 near the gearbox connecting seat platform 104. The support seat includes a motor support seat side plate 3. The motor support seat side plate 3 is vertically fixedly connected to the motor support seat platform 303 to form an L-shaped structure. A slider 301 is provided on the side of the motor support seat side plate 3 away from the motor support seat platform 303. The slider 301 is used to slide within the slide groove 101. The L-shaped structure design enhances the structural stability of the connecting seat and the support seat. The cooperation between the slide groove 101 and the slider 301 can not only further limit the relative movement direction of the support seat and the connecting seat, ensuring that they slide smoothly along the axis of the centering bolt 2, but also increase the smoothness and fluidity of the sliding of the support seat, which helps to improve the convenience of installation operations.

[0028] In a preferred embodiment, the slide groove 101 is a T-shaped slide groove 101, and the slider 301 is a T-shaped slider 301 that matches the slide groove 101. The cooperation between the T-shaped slide groove 101 and the T-shaped slider 301 provides better guidance and anti-disengagement performance. The mutual cooperation of the T-shaped structures can prevent the slider 301 from falling out of the slide groove 101 during sliding, ensuring the connection stability between the support base and the connecting base, and further improving the reliability of the entire installation aid during use.

[0029] In a preferred embodiment, the driving component is a lifting screw 501, and the motor support seat side plate 3 is provided with a lifting screw hole 302. The lifting screw 501 is threadedly connected to the lifting screw hole 302, and the bottom end of the lifting screw 501 is used to abut against the top surface of the gearbox connecting seat platform 104. The axis of the lifting screw hole 302 is parallel to the axis of the centering bolt 2. By rotating the lifting screw 501, the support seat can be raised and lowered in the axial direction of the centering bolt 2. The operation is simple and precise. At the same time, the parallel setting ensures that the centering accuracy is not affected during the raising and lowering process, and the motor height is precisely controlled to achieve better docking.

[0030] In a preferred embodiment, a hexagonal nut 5 is provided at the top of the lifting screw 501. The hexagonal nut 5 makes it easy to rotate the lifting screw 501 with tools, and can be operated without special tools, which reduces the difficulty of operation and improves the efficiency and convenience of fine-tuning the motor height during installation.

[0031] In a preferred embodiment, the centering bolt 2 includes a threaded rod 201, a bolt boss 202, and a hexagonal socket 203. A second upper recess 102 is provided on the top of the support platform hole 103. The bolt boss 202 is fixedly connected to the top of the threaded rod 201 and is fitted into the second upper recess 102. The hexagonal socket 203 is located in the middle of the top surface of the threaded rod 201. The fitting of the bolt boss 202 and the second upper recess 102 allows the centering bolt 2 to be better positioned and fixed in the support platform hole 103, enhancing the stability of the connection. The hexagonal socket 203 facilitates installation and disassembly using appropriate tools, improving the convenience and accuracy of installing the centering bolt 2.

[0032] In a preferred embodiment, the outer diameter of the bolt boss 202 is the same as the diameter of the second upper recess 102. The same outer diameter can achieve a precise fit between the bolt boss 202 and the second upper recess 102, so that the centering bolt 2 can be positioned more accurately during installation, avoiding deviations, and further improving the stability and accuracy of the connection between the centering bolt 2 and the gearbox connecting seat platform 104.

[0033] In a preferred embodiment, the bottom surface of the motor support platform 303 is provided with a recessed platform 305. The recessed platform 305 is collinear with the axis of the first upper recessed platform 304, and the diameter of the recessed platform 305 is not less than the diameter of the bolt boss 202. The setting of the recessed platform 305 increases the stability of the motor support platform 303 when in contact with the lower component. The collinear setting with the first upper recessed platform 304 further ensures the coaxiality of the structure. The diameter is not less than the diameter of the bolt boss 202. When the diameters of the two are the same, the matching degree between the motor support platform 303 and the top part of the centering bolt 2 can be further optimized.

[0034] In a preferred embodiment, a tapered column 401 is provided at the top of the centering plate 4. The tapered column 401 is collinear with the axis of the centering plate 4, and its cross-sectional area gradually decreases from bottom to top. The tapered column 401 structure provides better guidance when guiding the centering plate 4 into the motor flange hole, enabling automatic correction and centering. Its gradually decreasing cross-sectional area design allows for smoother entry into the flange hole, reducing obstruction and improving the centering efficiency and accuracy of motor installation.
