DETAILED DESCRIPTION
[0020] The present invention will be further described below with reference to the specific embodiments in the accompanying drawings.
[0021] See also Figures 1-4, an external lifting motor and brake rapid cooling device, comprising a mounting frame 2, the mounting frame 2 is square, an axial flow fan 7 is bolted to the mounting frame 2, a retractable connecting structure is provided at the bottom of the mounting frame 2, the mounting frame 2 is connected to the lifting motor base through the connecting structure, a frame column 6 is provided at the bottom of the mounting frame 2, there are multiple frame columns 6, and there are four frame columns 6 in total; an axial flow fan 7 is installed on one side of the lifting motor, and the axial flow fan 7 is started to quickly cool down the lifting motor and the brake, so as to ensure that the equipment can run for a long time at a certain temperature, extend the service life of the equipment to the greatest extent, and be conducive to the stable operation of production; the power supply of the axial flow fan 7 is connected in parallel with the power supply of the brake, and the axial flow fan 7 will be started at the same time when the brake is actuated, which effectively reduces the loss of electric energy and saves electricity costs.
[0022] In this embodiment, a rubber pad 3 is provided on the mounting frame 2, and the rubber pad 3 is installed between the base of the axial flow fan 7 and the mounting frame 2. Since the connection between the mounting frame 2 and the lifting motor base 1 is a rigid connection, the axial flow fan 7 and the lifting motor will vibrate during operation. When there is resonance between the two, the connecting rod 15 and the mounting frame 2 will lose stability, causing the axial flow fan 7 and the lifting motor to be not on the same horizontal plane, thereby reducing the cooling effect of the axial flow fan 7; and long-term accumulation of resonance will cause cracks in the mounting frame 2 and the connecting rod 15, affecting their service life.
[0023] In this embodiment, the connecting structure includes a fixed rod 4 and a sliding rod 5, one end of the fixed rod 4 is connected to the lifting motor base 1, and one end of the sliding rod 5 is connected to the mounting frame 2. A slider 8 is provided at the bottom of the sliding rod 5, and the slider 8 is in an I-shape. A sliding groove 9 adapted to the slider 8 is provided on the fixed rod 4, and the slider 8 is slidably installed in the sliding groove 9. The distance between the axial flow fan 7 and the lifting motor can be adjusted through the sliding connection between the fixed rod 4 and the sliding rod 5, thereby improving the cooling effect of the axial flow fan 7, avoiding the axial flow fan 7 and the lifting motor from colliding due to the distance between the two being too close, causing damage, or avoiding the axial flow fan 7 and the lifting motor from being too far away, thereby reducing the cooling effect of the axial flow fan 7.
[0024] In this embodiment, the sliding rod 5 is provided with a counter-top screw 10 threadedly connected thereto, the counter-top screw 10 passes through the sliding block 8, and one end of the counter-top screw 10 contacts the bottom of the sliding groove 9. When the sliding block 8 moves to the desired position in the sliding groove 9, the counter-top screw 10 is tightened so that one end of the counter-top screw 10 contacts the bottom of the sliding groove 9, thereby achieving the effect of fixing the sliding block 8.
[0025] In this embodiment, the fixing rod 4 is threadedly connected to a limiting bolt 11, which passes through the slide groove 9. The limiting bolt 11 is horizontally installed in the slide groove 9 to limit the movement of the slider 8 to prevent the slider 8 from continuing to move when it moves to the limit position.
[0026] In this embodiment, a nut 12 is provided at the top of the fixed rod 4. The nut 12 is threadedly connected to a lead screw 13. One end of the sliding rod 5 close to the fixed rod 4 is provided with a bearing 14. One end of the lead screw 13 is rotatably connected to the bearing 14. By rotating the lead screw 14, the distance between the axial flow fan 6 and the hoisting motor can be adjusted; at the same time, the connection between the lead screw 13 and the sliding rod 5 can improve the connection strength between the mounting frame 2 and the hoisting motor base 1.
[0027] In this embodiment, a connecting rod 15 threadedly connected thereto is provided at the bottom of the frame column 6. A self-locking universal wheel 16 is provided at the bottom of the connecting rod 15. The self-locking universal wheel 16 is threadedly connected to the frame column 6 through the connecting rod 15, which is convenient for the maintenance and replacement of the self-locking universal wheel 16; when moving the mounting frame 2, through the self-locking universal wheel 16, the frame column 6 will not rub against the surface of the equipment and cause wear. At the same time, the self-locking universal wheel 16 is convenient for the movement of the mounting frame 2. When the mounting frame 2 moves to the required position, the self-locking universal wheel 16 can be locked; the frame column 6 improves the stability of the mounting frame 2, so that the axial flow fan 7 and the hoisting motor are kept on the same horizontal plane, greatly improving the cooling effect of the axial flow fan.
[0028] In this embodiment, the axial flow fan 7 is electrically connected to the brake; only when the brake acts, the axial flow fan 7 will start at the same time, which effectively reduces the power consumption and saves the electricity cost.
[0029] The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can be made, which will not affect the implementation effect of the present invention and the practicality of the patent.
