At present, the position of the explosion-proof motor is generally fine-tuned by using a pad. However, when fine-tuning the position of the explosion-proof motor by using a pad, it is difficult to adapt to a suitable pad, so there is a defect of inconvenient adjustment of the position of the explosion-proof motor.

The same group of guide portions 13 includes two guide portions 13, and the two guide portions 13 of the same group clamp the reference seat 11 and the fixed seat 12.

[0031] The guide portion 13 includes a guide plate 131, a first guide bolt 132 and a second guide bolt 133. The guide plate 131 is provided with a waist groove along the length direction of the guide plate 131, and the first guide bolt 132 and the second guide bolt 133 are both slidably matched with the waist groove. The first guide bolt 132 corresponds to the reference seat 11, and the second guide bolt 133 corresponds to the fixed seat 12. The first guide bolt 132 is fixedly mounted on the side wall in the length direction of the reference seat 11, and a limiting groove 121 is provided on the side wall in the length direction of the fixed seat 12 along the length direction of the fixed seat 12, and the second guide bolt 133 is slidably matched with the limiting groove 121.

[0032] When installing the guide part 13, the first guide bolt 132 is fixedly installed on the reference seat 11, and the first guide bolt 132 passes through the waist groove on the guide plate 131, and the second guide bolt 133 passes through the waist groove on the guide plate 131, and the second guide bolt 133 is located inside the limiting groove 121, and the groove wall of the limiting groove 121 limits the guide plate 131 through the second guide bolt 133.

[0033] Several height adjustment components 2 are arranged along the length direction of the reference seat 11. In the embodiment of the present application, two height adjustment components 2 are arranged. The two height adjustment components 2 are respectively located near the two ends of the reference seat 11, and the two height adjustment components 2 are located between the two groups of guide parts 13.

[0034] Two slide grooves 111 are provided on the top of the reference seat 11 . The length direction of the two slide grooves 111 corresponds to the width direction of the reference seat 11 , and the two slide grooves 111 correspond to the two height adjustment components 2 one by one.

[0035] Each height adjustment assembly 2 includes a pressure-bearing portion 21 and an adjustment portion 22 .

[0036] There are two pressure-bearing parts 21, each of which includes a slider 211 and an adjusting block 212. The slider 211 is located inside the corresponding slide groove 111, and the slider 211 and the corresponding slide groove 111 are slidably matched. The adjusting block 212 is located on the top of the slider 211. The adjusting block 212 is detachably fixed on the slider 211 by multiple bolts, and a downward inclined surface is provided on the side of the adjusting block 212 close to the fixed seat 12.

[0037] The adjusting part 22 includes an adjusting screw 221 and a power unit 222. The adjusting screw 221 is located inside the slide groove 111, and the length direction of the adjusting screw 221 is consistent with the length direction of the slide groove 111. The adjusting screw 221 is provided with two sections of threads with opposite rotation directions, and the two sections of threads with opposite rotation directions correspond to two sliders 211 inside the same slide groove 111 one by one. The adjusting screw 221 is spirally passed through the two sliders 211 inside the same slide groove 111, and the two ends of the adjusting screw 221 are rotated to pass through the groove wall of the slide groove 111.

[0038] Two power units 222 are provided, and the two power units 222 are respectively located at the two ends of the adjusting screw rod 221. The power unit 222 includes a rotating disk 2221 and a mounting tube 2222. The mounting tube 2222 is coaxially fixedly installed on a side of the rotating disk 2221 close to the adjusting screw rod 221, and the mounting tube 2222 is sleeved on the end of the adjusting screw rod 221, and the mounting tube 2222 and the adjusting screw rod 221 are fixedly connected. At the same time, in order to facilitate the rotation of the rotating disk 2221, a plurality of rotation grooves are also provided on the rotating disk 2221.

[0039] The implementation principle of an adjustable base for an explosion-proof motor in an embodiment of the present application is: when installing the explosion-proof motor, the reference base 11 is fixedly installed at a position close to the driven part, and when the height of the explosion-proof motor needs to be fine-tuned, the explosion-proof motor is fixedly installed on the top of the fixed base 12. According to the height position that the explosion-proof motor needs to be adjusted, the staff rotates the turntable 2221 through the rotating groove on the turntable 2221, and the turntable 2221 drives the adjusting screw rod 221 to rotate through the mounting tube 2222. Since the two sliders 211 and the two sections of threads with opposite rotation directions on the adjusting screw rod 221 correspond one to one, when the adjusting screw rod 221 rotates, the two sliders 211 drive the adjusting blocks 212 on the sliders 211 to synchronously approach or move away from each other, thereby improving the stability of the supporting fixed seat 12. When the two adjusting blocks 212 move closer to each other, the inclined surface on the adjusting block 212 guides the fixed seat 12, so that the fixed seat 12 drives the explosion-proof motor to move in the vertical direction, so as to adjust the height of the explosion-proof motor. When the fixed seat 12 moves in the vertical direction, the guide plate 131 guides the fixed seat 12 through the first guide bolt 122 and the second guide bolt 133, so as to improve the accuracy of the moving direction of the fixed seat 12. When the working angle of the explosion-proof motor needs to be fine-tuned, the distance between the two adjustment blocks 212 in the two sets of height adjustment components 2 can be made inconsistent through the adjustment part 22, thereby improving the convenience of fine-tuning the working angle of the explosion-proof motor. When the front and rear positions of the explosion-proof motor need to be fine-tuned, the distance between the two adjustment blocks 212 in the two sets of height adjustment components 2 can be made consistent through the adjustment block 212, and then the fixing seat 12 can be directly moved in the horizontal direction.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
