Moving parts 7 are installed on the tops of the two second electric sliders 31, and through grooves 30 are provided inside the two moving parts 7. When the second electric slider 31 drives the moving part 7 to move, the two first telescopic rods 20 can be controlled to rotate into the through grooves 30 respectively, so that the moving plate 5 can be driven to move synchronously on the top of the motor body 1 while the second electric slider 31 moves.

[0031] As a technical optimization solution of the present invention, two retractable rotating members 6 are rotatably installed on the outer wall of the motor body 1 near the motor output end 2 through the rotating shaft 16. The outer wall of the rotating shaft 16 is provided with a rectangular groove. The two rotating members 6 can move back and forth in the rectangular groove through the protrusions provided on the inner wall. The ends of the two rotating members 6 away from the rotating shaft 16 are jointly provided with a third telescopic rod. The rotating member 6 can limit the moving distance of the moving plate 5, and can also contact the movement of the two second telescopic rods 23 and the first electric slider 27 after the moving plate is transferred to a position close to the motor output end 2, and abut against the rotating member 6, so as to limit and fix the position of the moving plate 5.

[0032] As a technical optimization solution of the present invention, the mounting mechanism includes two fourth slide grooves 10 opened on the outer walls of the motor body 1 on opposite sides, and the second sliding blocks 12 are slidably mounted inside the plurality of fourth slide grooves 10, and the ends of the plurality of second sliding blocks 12 away from the motor body 1 are all mounted with mounting seats 11. The positions of the plurality of mounting seats 11 in the fourth slide grooves 10 can be adjusted according to the installation requirements of the motor body 1, so that the motor body 1 can be installed at different positions.

[0033] In the present invention, before the motor body 1 is used, the mounting seat 11 can be adjusted in the fourth slide groove 10 according to the different installation positions during the working process, and after the position of the mounting seat 11 is adjusted, the mounting seat 11 is connected to the installation position through multiple fixings, so that the motor body 1 can be installed in the specified working position; during the actual use of the motor body 1, after the cable is connected to the electrical port 32 set on the top of the motor body 1, the two first telescopic rods 20 and the second telescopic rods 23 in the first groove 18 and the two second grooves 22 are controlled to rotate to a horizontal and vertical state, and then the telescopic ends of the two first telescopic rods 20 and the second telescopic rods 23 are controlled to be in an extended state. At this time, the movable plate 5 can be pushed in the first slide groove 8 toward the direction close to the rotating block 4, so that the two The telescopic ends of the first telescopic rod 20 and the second telescopic rod 23 are both inserted into the first slot 14 on the outer wall of the rotating block 4 to support the movable plate 5 and the movable rod 21. Then the two first electric sliders 27 can be controlled to move in the direction of approaching each other inside the second slide groove 17, driving the two movable rods 21 and the clamping plates 24 installed on the outer wall of the adjacent side to move in the direction of approaching each other, until the rubber pads 26 installed inside the two clamping plates 24 are tightly against the outer wall of the cable, so that the cable can be clamped and fixed. When the motor body 1 vibrates during operation, the cable installed inside the electrical port 32 will not shake more violently due to the vibration, and the position where the vibration occurs will be transferred to the position in contact with the clamping plate 24, thereby improving the stability of the connection between the cable and the electrical port 32.

[0034] When the two clamping plates 24 cooperate to clamp and fix the cable, the telescopic sleeve 15 can be controlled to be in an extended state, so that the end of the telescopic sleeve 15 away from the rotating block 4 is inserted into the arc-shaped groove 25 opened on the outer walls of the two clamping plates 24. Since the end of the telescopic sleeve 15 away from the rotating block 4 is equipped with a protective cover 33 made of dustproof cloth, when the end of the telescopic sleeve 15 equipped with the protective cover 33 is inserted into the arc-shaped groove 25, the protective cover 33 is soft in texture, so that the connection and seal between the telescopic sleeve 15 and the clamping plate 24 are more tightly, and the telescopic sleeve 15 in the extended state can The connection part between the electrical port 32 and the cable is protected to prevent the motor body 1 from being used in a harsh environment. Debris in the external environment can easily enter the connection part between the electrical port 32 and the cable, affecting the normal use of the cable and the electrical port 32. At the same time, the telescopic ends of the two first telescopic rods 20 can be controlled to retract, and then the two first telescopic rods 20 can be controlled to rotate 90 degrees in the direction away from each other, so that the ends of the two first telescopic rods 20 away from the moving plate 5 are rotated into the through groove 30 inside the moving part 7, and the second electric slider 31 can be controlled to move in the third slide groove 9. The movable plate 5 can be synchronously driven to move on the top of the motor body 1, that is, within the maximum length range of the telescopic sleeve 15, the movable member 7 and the movable plate 5 can be driven to move by means of the second electric slider 31, and the position of the two clamping plates 24 clamping the cable can be adjusted, so as to facilitate switching of the clamping position of the two clamping plates 24 on the cable, and avoid the two clamping plates 24 clamping and fixing the same part of the cable for a long time, resulting in deformation and aging of the clamped part of the cable; and when the electrical port 32 is not connected to the cable, the protective cover 33 can be stretched out and moved away The closing portion of the draw cord at one end of the telescopic sleeve 15 is closed so that the protective cover 33 can protect the electrical port 32 at this time, preventing foreign matter from entering the interior of the electrical port 32 through the opening of the electrical port 32, thereby affecting the subsequent connection with the cable; even after the cable is connected to the electrical port 32, when the other end of the cable has not yet been connected to other equipment, the protective cover 33 can be stretched to the maximum length to protect the motor port 32 and the cable as a whole, thereby preventing the other end of the cable from being exposed to the outside, thereby causing problems in the subsequent connection with other equipment.

[0035] When the motor output end 2 of the motor body 1 needs to be connected with the reduction gear, the two first electric sliders 27 can be controlled to move in the second slide groove 17 in the direction away from each other, driving the two clamping plates 24 to release the clamping and fixing of the cable, but the telescopic sleeve 15 is still in the extended state to protect the cable and prevent excessive shaking. Then the rotating member 6 is rotated from the inside of the first slide groove 8 toward the direction close to the motor output end 2 to a horizontal state. At this time, the rotating member 6 no longer blocks and limits one end of the first slide groove 8. The movable plate 5 can be manually slid out of the first slide groove 8, and the telescopic ends of the two first telescopic rods 20 can be controlled to extend. The staff can insert the two first telescopic rods 20 in the extended state into the two second slots 13 near the motor output end 2, and then the two second telescopic rods 23 can be controlled to rotate upward to a vertical state, and the telescopic ends of the two second telescopic rods 23 can be controlled to extend upward. The two first electric sliders 27 are controlled again to drive the two clamping plates 24 and the rubber pads 26 to move towards each other until the two rubber pads 26 are tightly abutted against the outer wall of the motor output end 2, and the outer wall of the side close to the telescopic ends of the two second telescopic rods 23 is also tightly abutted against the rotating member 6, so that the movable plate 5 can be stably supported at the end of the motor body 1 close to the motor output end 2, and the two clamping plates 24 and the rubber pads 26 tightly abutted against the outer wall of the motor output end 2 can be used as oil seals to prevent the lubricating oil of the reduction gear from flowing into the interior of the motor body 1 along the motor output end 2, which will have a certain impact on the normal use of the motor body 1; and because the motor output end 2 is clamped and fixed by the two clamping plates 24 during the rotation process, it can also indirectly improve the stability of the rotation of the motor output end 2, and avoid vibration of the motor output end 2 and the transmission of vibration to the electrical port 32 and the cable connection part.

[0036] And when the two clamping plates 24 and the rubber pad 26 are used as oil seals on the outer wall of the motor output end 2, the lubricating oil overflowing from the reduction gear can be directed downward on the outer wall of the clamping plates 24 and the rubber pad 26, and the lubricating oil is directed to the inside of the second slide groove 17 on the top of the movable plate 5 for collection. After the lubricating oil flows into the inside of the second slide groove 17, it can lubricate the surfaces of the two first electric sliders 27, so that the two first electric sliders 27 can move more smoothly inside the second slide groove 17; when the lubricating oil inside the second slide groove 17 is collected enough, the movable plate 5 can be manually slid and installed again inside the first slide groove 8, and then the two first electric sliders can be controlled 27 moves to the maximum distance in the direction away from each other inside the second slide groove 17, and the lubricating oil inside the second slide groove 17 can flow downward into the sponge pad 29 through the circular groove 28 opened inside the two first sliding blocks 19 for adsorption, and then the two first telescopic rods 20 can be controlled to rotate again into the through groove 30 inside the two moving parts 7, and the second electric slider 31 is used to slowly move back and forth in the third slide groove 9, driving the two first sliding blocks 19 at the bottom of the mounting plate 5 to move synchronously in the first slide groove 8, and automatically smearing the lubricating oil adsorbed in the two sponge pads 29 inside the first slide groove 8, so as to facilitate the first sliding block 19 to move more smoothly in the first slide groove 8.

[0037] When the motor body 1 needs to be transported, since there is no lifting ring connected to the lifting mechanism at the top of the motor body 1, it is not convenient for the motor body 1 to be lifted and transported. At this time, the two first electric sliders 27 can be continuously controlled to move in the direction of approaching each other inside the second slide groove 17 until the two clamping plates 24 are connected to form an annular plate, and then the rotating member 6 is controlled to rotate upward to a vertical state, and its height is adjusted to keep the height consistent with the height of the two clamping plates 24 connected. At this time, the annular plate formed by the two clamping plates 24 connected to each other and the rotating member 6 rotated upward to a vertical state can be used as two temporary lifting rings respectively, which is convenient for the connection between the external lifting mechanism and the motor body 1, so that the motor body 1 can be conveniently lifted and transported; and after the two clamping plates 24 are connected, the two first telescopic rods 20 can be synchronously controlled to rotate into the through grooves 30 inside the two moving members 7, so that the two first telescopic rods 20 inside the through grooves 30 can improve the support for the moving plate 5, improve the stability of the connection between the moving plate 5 and the motor body 1, and ensure the safety of the motor body 1 during lifting and transportation.
