Description

Technical Field

[0001] The utility model relates to the technical field of coupling protective covers, in particular to a novel protective cover. Background Art

[0002] The protective cover of the coupling is an important part of the chemical process pump unit. The cylindrical protective cover can fully cover the entire coupling, and objects larger than 5mm cannot come into contact with the rotating parts, meeting the API682 standard.

[0003] In the process of putting the traditional coupling guard into use, it was found that when the coupling needs to be rotated or adjusted, the entire coupling guard needs to be removed for maintenance, but the coupling guard must be reinstalled after the maintenance. The whole operation process is relatively cumbersome, time-consuming and labor-intensive, and due to the high requirements and high strength, and the thickness of the positioning plate is only about 4 mm, it can only be fixed to the positioning plate by clamping, which greatly limits the application of the cylindrical guard.

[0006] The effect achieved by the above components is: when the coupling needs to be rotated or adjusted, the upper inner protective cover can be flipped open to inspect the coupling. After the inspection is completed, it is only necessary to put the upper inner protective cover back on the lower inner protective cover, which is easy to operate and saves time and effort.

[0012] The effect achieved by the above components is that after the lower outer protective cover is slid to a suitable position, the butterfly screw can be rotated to quickly fix the position of the lower outer protective cover with the help of the butterfly screw.

[0013] Preferably, one end of the upper outer protective cover and the lower outer protective cover are fixedly connected to an ear plate, and a screw is slidably inserted in the two ear plates. Knobs are provided at the upper and lower ends of the screw, the knob at the upper end of the screw is threadedly connected to the screw, and the knob at the lower end of the screw is fixedly connected to the screw.

[0014] The effect achieved by the above components is that after the upper outer protective cover and the lower outer protective cover are buckled together, the upper outer protective cover and the lower outer protective cover can be quickly fixed.

[0023] Reference Figure 1 As shown, the utility model provides a technical solution: a new protective cover, including a motor 1, a coupling 2, a positioning plate 4 and a bearing box 3, the output end of the motor 1 is fixedly installed with the coupling 2, the other end of the coupling 2 is fixedly connected to the output end of the bearing box 3, the side of the bearing box 3 close to the coupling 2 is fixedly connected with the positioning plate 4, and the side of the positioning plate 4 close to the coupling 2 is provided with a protective mechanism 5.

[0024] The specific setting and function of the protection mechanism 5 will be described in detail below.

[0025] Reference Figure 2 , Figure 3 , Figure 4 as well as Figure 5As shown, in this embodiment: the protection mechanism 5 includes two screw members 51, the two screw members 51 are symmetrically spot-welded and connected to the positioning plate 4, the two screw members 51 are sleeved with a lower inner protective cover 53, the screw members 51 are threadedly connected with a nut 52, the nut 52 is located outside the lower inner protective cover 53, one end of the lower inner protective cover 53 is welded with a connecting seat 58, and the upper inner protective cover 54 is rotatably connected in the connecting seat 58. When the coupling 2 needs to be turned or adjusted, the upper inner protective cover 54 can be turned over to overhaul the coupling 2. After the overhaul is completed, it is only necessary to re-cover the upper inner protective cover 54 on the lower inner protective cover 53, which is easy to operate and saves time and effort. A bayonet is opened at one end of the screw member 51 close to the positioning plate 4, and the screw member 51 is spot-welded and connected to the positioning plate 4 by means of the bayonet, so as to achieve the effect of quickly positioning the lower inner protective cover 53 and the positioning plate 4 when the lower inner protective cover 53 is installed. An extension component 55 is provided on the outside of the upper inner protective cover 54 and the lower inner protective cover 53, and the extension component 55 includes an upper outer protective cover 554 and a lower outer protective cover 551. The upper outer protective cover 554 and the lower outer protective cover 551 are respectively slidably mounted on the outside of the upper inner protective cover 54 and the lower inner protective cover 53, and one end of the upper outer protective cover 554 and the lower outer protective cover 551 are hinged to each other, and a slide groove 552 is provided at the lower end of the lower outer protective cover 551, and a stud is fixedly inserted at the position of the lower inner protective cover 53 corresponding to the slide groove 552. The stud is located inside the slide groove 552, and a butterfly screw 553 is threaded on the stud, and the butterfly screw 553 is located on the outside of the lower outer protective cover 551, so that the upper outer protective cover 554 and the lower outer protective cover 551 can slide on the upper inner protective cover 54 and the lower inner protective cover 53 respectively, so that the protection range can be adjusted according to different sizes of couplings 2 or motors 1 to improve adaptability. The cross-sectional size of the butterfly screw 553 is larger than the width of the slide slot 552. After the lower outer protective cover 551 is slid to a suitable position, the butterfly screw 553 can be rotated to quickly fix the position of the lower outer protective cover 551. One end of the upper outer protective cover 554 and the lower outer protective cover 551 are fixedly connected with an ear plate 56, and a screw rod is slidably inserted in the two ear plates 56. The upper and lower ends of the screw rod are provided with a knob 57. The knob 57 at the upper end of the screw rod is threadedly connected to the screw rod, and the knob 57 at the lower end of the screw rod is fixedly connected to the screw rod. After the upper outer protective cover 554 and the lower outer protective cover 551 are buckled together, the upper outer protective cover 554 and the lower outer protective cover 551 can be quickly fixed.

[0026] Working principle: during the first installation, the screw part 51 on the lower inner protective cover 53 is first clamped on the positioning plate 4 with the help of the bayonet, and then the screw part 51 is fixed to the positioning plate 4 by spot welding. At this time, the lower inner protective cover 53 and the lower outer protective cover 551 are stably fixed on the positioning plate 4. Then, the upper inner protective cover 54 and the upper outer protective cover 554 are flipped over and buckled onto the lower inner protective cover 53 and the lower outer protective cover 551, and finally, the screw is inserted into the two ear plates 56, and then the knob 57 above the screw is turned so that the knob 57 moves downward with the help of the thread to squeeze the two ear plates 56 together, and then the upper outer protective cover 554 and the lower outer protective cover 551 are slid. At this time, the studs on the lower inner protective cover 53 will slide along the inside of the slide groove 552 of the lower outer protective cover 551. After one end of the upper outer protective cover 554 and the lower outer protective cover 551 is pressed against one side of the motor 1, the butterfly screw 553 is turned, and the butterfly screw 553 is used to fix the position of the lower outer protective cover 551 and the upper outer protective cover 554. At this time, the coupling 2 is in a state of being protected.

[0027] When it is necessary to rotate or adjust the coupling 2, hold the knob 57 below the ear plate 56 and then turn the knob 57 above the ear plate 56 to unscrew the upper knob 57 from the screw rod, and then pull the screw rod out from under the two ear plates 56. At this time, the upper outer protective cover 554 and the lower outer protective cover 551 can be directly flipped open, and the coupling 2 can be directly rotated or adjusted. Compared with the traditional method, there is no need to disassemble it completely, so it is easy to operate and saves time.
