Therefore, they should not be construed as limitations on this utility model.
[0025] Example 1:
[0026] This embodiment discloses an auxiliary clamping device for repairing large mining motors. Through the coordinated design of the lifting component 2 and the drive mechanism 3, the height of the repair platform 4 can be adjusted, thereby allowing the large motor on the repair platform 4 to be adjusted to a suitable height. This not only facilitates repair work for maintenance personnel of different heights but also effectively improves maintenance efficiency. Referring to Figures 1-5, it mainly includes a base frame 1. The repair platform 4 is mounted on the upper end of the base frame 1, which can move up and down via the lifting component 2. The lower end of the repair platform 4 is equipped with a drive mechanism 3 that can drive the lifting component 2. The upper end of the repair platform 4 is equipped with a clamping mechanism 5 that can clamp the large motor. Through the ingenious design of the clamping mechanism 5, the large motor can be clamped and fixed, effectively preventing the large motor from sliding or moving randomly during the repair process, which would affect maintenance efficiency.
[0027] To adjust the height of the service bench 4, in this embodiment, referring to Figures 1, 2, and 3, the lifting assembly 2 includes a first support rod 201, a second support rod 202, a middle connecting rod 204, and a lower connecting rod 203. The first support rods 201 are symmetrically mounted on both sides of one end of the base frame 1. The ends of the two first support rods 201 away from the base frame 1 are slidably connected to the lower end of the service bench 4, and these ends are driven by a drive mechanism 3. The lower connecting rod 203 is slidably connected to the other end of the base frame 1. The two ends of the lower connecting rod 203 are aligned with... The two second support rods 202 are rotatably connected. The ends of the two second support rods 202 away from the base frame 1 are rotatably connected to the lower end of the maintenance platform 4. The second support rods 202 and the first support rods 201 are rotatably connected through the middle connecting rod 204. In actual use, when the drive mechanism 3 rotates the two first support rods 201, the second support rods 202 located on the base frame 1 can be rotated through the cooperation of the middle connecting rod 204 and the lower connecting rod 203, so that the height of the maintenance platform 4 can be adjusted as needed.
[0028] To drive the two first support rods 201, in this embodiment, referring to Figures 1, 2, and 3, the drive mechanism 3 includes a first motor 301, a driving bevel gear 302, a driven bevel gear 303, a lead screw 304, and a threaded connecting rod 305. The first motor 301 is mounted on one side of the maintenance platform 4. The output shaft of the first motor 301 is equipped with the driving bevel gear 302. The threaded connecting rod 305 is rotatably mounted between the ends of the two first support rods 201 away from the base frame 1. The middle part of the threaded connecting rod 305 is threadedly connected to the lead screw 304 through a threaded hole. Installed at the lower end of the maintenance platform 4, the lead screw 304 is equipped with a driven bevel gear 303 that meshes with the driving bevel gear 302. In actual use, the first motor 301 is started, and the first motor 301 drives the driving bevel gear 302 to rotate. The meshing of the driving bevel gear 302 and the driven bevel gear 303 causes the lead screw 304 to rotate. The lead screw 304 drives the threaded connecting rod 305 to rotate. However, under the limit of the two first support rods 201, the threaded connecting rod 305 moves, thereby driving the first support rods 201 to rotate.
[0029] To clamp and secure large motors for easy maintenance, in this embodiment, referring to Figures 1 and 3, the clamping mechanism 5 includes a mounting base 501, a spur gear plate 502, a drive gear 503, a second motor 504, and a clamping plate 505. The upper end of the maintenance platform 4 is symmetrically and fixedly connected to the mounting base 501. A spur gear plate 502 is slidably connected to the middle of the upper end of each mounting base 501. One end of two adjacent spur gear plates 502 is fixedly connected to a clamping plate 505 for clamping the large motor. A second motor 504 is mounted on one side of the mounting base 501. A drive gear 503, meshing with the spur gear plate 502, is mounted on the output shaft of the second motor 504. In actual use, starting the second motor 504 drives the drive gear 503 to rotate. The drive gear 503 meshes with the spur gear plate 502, causing the spur gear plate 502 to slide, thereby allowing the clamping plate 505 to clamp and secure the large motor, facilitating maintenance by personnel.
[0030] To prevent damage to the large motor during clamping, a sponge pad is installed on the clamping plate 505 in this embodiment. The sponge pad prevents damage to the large motor when the clamping plate 505 clamps it.
[0031] To facilitate the movement of the device, in this embodiment, referring to Figures 1, 2, and 3, casters 7 are installed at the four corners of the lower end of the base frame 1.
[0032] Example 2:
[0033] Based on Embodiment 1, this embodiment discloses an auxiliary clamping device for the maintenance of large mining motors. By setting the limiting component 6, the second support rod 202 can be limited, further improving the stability of the device. Referring to Figures 1, 2, 3, and 4, the limiting components 6 are symmetrically installed at both ends of the lower connecting rod 203. The limiting component 6 includes a rotating plate 601, a mounting cylinder 602, an opening 603, a spring 604, a sliding plate 605, and a connecting shaft 606. The rotating plate 601 is rotatably connected to the lower connecting rod 203. The mounting cylinder 602 is fixedly connected to the rotating plate 601. The interior of the mounting cylinder 602 is fixedly connected to one end of the spring 604. The other end of the spring 604 is fixedly connected to the sliding plate 605. The end of the sliding plate 605 away from the spring 604 is fixedly connected to the connecting shaft 606. The mounting cylinder 602 has an opening for the sliding plate 605 to move left and right. The base frame 1 has several through holes for inserting the plug shaft 606. In actual use, after adjusting the maintenance platform 4 to a suitable height, manually slide the sliding plate 605 until the plug shaft 606 does not interfere when the rotating plate 601 rotates. Rotate the rotating plate 601 until it can insert the plug shaft 606 into the through hole. At this time, release the sliding plate 605. Under the action of the spring 604, the plug shaft 606 will be inserted into the through hole, which can limit the second support rod 202, thereby making the second support rod 202 support effect better and further improving the stability of the device.
[0034] To limit the rotation plate 601 and prevent it from moving left or right, in this embodiment, referring to Figure 5, a grooved ring 205 is provided on the lower connecting rod 203 to limit the rotation plate 601.
[0035] The working principle of the auxiliary clamping device for repairing large mining motors of this utility model is as follows: When a large motor needs to be repaired, it is placed in the middle of the repair platform 4. The second motor 504 is started, which drives the drive gear 503 to rotate. The drive gear 503 meshes with the spur gear plate 502, causing the spur gear plate 502 to move, thereby causing the clamping plate 505 to clamp and fix the large motor. After clamping and fixing is completed, the first motor 301 is started, which drives the drive bevel gear 302 to rotate. The engagement of gear 302 and driven bevel gear 303 causes the lead screw 304 to rotate. The lead screw 304 drives the threaded connecting rod 305 to rotate. However, under the limit of the two first support rods 201, the threaded connecting rod 305 moves, thereby causing the two first support rods 201 to rotate. During the rotation, through the cooperation of the lower connecting rod 203 and the middle connecting rod 204, the second support rod 202 located on the base frame 1 rotates, thereby adjusting the height of the maintenance platform 4, so as to facilitate maintenance personnel of different heights to maintain the large motor.
