Description

Technical Field

[0001] This utility model relates to the field of docking assistance for clean pipelines, specifically an auxiliary mechanism for the installation of clean pipelines. Background Technology

[0002] Clean pipelines refer to pipeline systems used to transport substances with high purity, high precision, and high quality requirements.

[0003] After production, clean pipelines need to be thoroughly cleaned and disinfected. After cleaning and disinfection, caps are put on the ends of the pipelines to prevent the inside of the pipelines from coming into contact with the external environment again.

[0004] In existing technologies, when installing clean pipelines, the cap is usually opened and the pipeline is installed directly. This installation method is relatively convenient, but during the installation process, the external environment will directly interact with the inside of the pipeline, resulting in a decrease in the cleanliness of the pipeline's inner wall. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary mechanism for the installation of clean pipelines in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary mechanism for clean pipeline installation, comprising a fixing ring sleeved on the connecting ends of two clean pipelines, one end of the fixing ring having an opening at 180 degrees, a fixing connecting sleeve fixedly connected to one end of the inner wall of the fixing ring, and a sliding connecting sleeve slidably connected to the other end of the inner wall of the fixing ring, a moving mechanism rotatably mounted on the fixing connecting sleeve and threadedly connected to the sliding connecting sleeve, sealing rings fixedly mounted on the inner walls of the fixing connecting sleeve and the sliding connecting sleeve, and a cap removal mechanism mounted on the end of the annular plates of the fixing connecting sleeve and the sliding connecting sleeve that are close to each other, the cap removal mechanism being used to separate the cap sleeved on the pipeline flange end.

[0007] As a further embodiment of this utility model: the moving mechanism includes a screw rotatably connected to the annular plate of the fixed docking sleeve, the screw being threadedly connected to the annular plate of the sliding docking sleeve, and a rotating handle being fixedly connected to the end of the screw away from the fixed docking sleeve.

[0008] As a further embodiment of this utility model: the hat removal mechanism includes a fixed ear fixedly connected to the fixed docking sleeve and the annular plate of the sliding docking sleeve. A hat removal plate is rotatably installed on the lower inner side of the fixed ear. The hat removal plate has grooves on both sides. A rotating shaft that is rotatably connected to the fixed ear is integrally formed at one end of the inner wall of the groove. A torsion spring is engaged between the inner wall of the groove and the fixed ear.

[0009] As a further improvement of this utility model: one end of the inner wall of the groove body and the inner side of the fixing ear that contacts the torsion spring are provided with a locking groove that engages with the end of the torsion spring.

[0010] As a further improvement of this utility model: the two ends of the sealing ring are integrally formed with a conical surface that is wider on the outside and narrower on the inside, and the outer diameter of the sealing cap is equal to the inner diameter of the hollow column of the fixed docking sleeve and the sliding docking sleeve.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By setting up a fixed docking sleeve, a sliding docking sleeve, a sealing ring, and a cap removal mechanism, the possibility of direct interaction between the internal and external environments of the pipeline can be reduced during the docking process of clean pipelines, thereby avoiding the problem of decreased cleanliness due to installation.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4In this embodiment of the present invention, an auxiliary mechanism for installing clean pipelines includes a fixing ring 1 sleeved on the connecting ends of two clean pipelines. One end of the fixing ring 1 has an opening 13 at 180 degrees. A fixing connecting sleeve 2 is fixedly connected to one end of the inner wall of the fixing ring 1, and a sliding connecting sleeve 3 is slidably connected to the other end of the inner wall of the fixing ring 1. A moving mechanism that is threadedly connected to the sliding connecting sleeve 3 is rotatably installed on the fixing connecting sleeve 2. Sealing rings 6 are fixedly installed on the inner walls of the fixing connecting sleeve 2 and the sliding connecting sleeve 3. A cap removal mechanism is installed on the end of the annular plates of the fixing connecting sleeve 2 and the sliding connecting sleeve 3 that are close to each other. The cap removal mechanism is used to separate the cap 9 sleeved on the flange end of the pipeline.

[0020] In this embodiment: First, the fixed docking sleeve 2 is docked with the fixed pipe. Then, the end of the other unfixed pipe is inserted into the inner wall of the sliding docking sleeve 3 until the ends of the two pipes that are close to each other enter the space between the sliding docking sleeve 3 and the fixed docking sleeve 2. Then, the device is moved, and through operation (e.g., manual pulling), the unfixed pipe and the device are moved synchronously. At this time, the device moves outward relative to the fixed pipe until the cap removal mechanism on the fixed docking sleeve 2 contacts the cap 9 on the fixed pipe. At this time, the cap 9 at one end of the fixed pipe can be removed, and the device is pulled to move, so that the outer periphery of the flange end of the fixed pipe contacts and abuts against the inner periphery of the sealing ring 6 on the inner periphery of the fixed docking sleeve 2. Then, the device is kept stationary, and the unfixed pipe is pulled outward. At this time, the cap removal mechanism on the sliding docking sleeve 3 contacts and pushes down the cap 9 on the outer periphery of the flange end of the unfixed pipe. The device is pulled continuously until the outer periphery of the flange end of the unfixed pipe contacts the inner periphery of the sealing ring 6 on the sliding docking sleeve 3.

[0021] After completing the above operations, by rotating the moving mechanism, the moving mechanism drives the sliding docking sleeve 3 to move towards the fixed docking sleeve 2 until the two are not far apart and the sliding docking sleeve 3 can no longer move. At this time, quickly push the unfixed pipe to dock with one end of the fixed pipe. After docking, the device can be pulled away from the docking position of the two pipes. During the movement of the device, the docking point of the two pipes can be kept stable by operation (e.g., manual support) until the device is separated from the docking position of the two pipes. At this time, use bolts and nuts to fix the two flanges.

[0022] The above methods can effectively reduce the contact between external air and the inner wall of the pipe, and maintain the cleanliness of the connection. It should be noted that the device should be soaked in disinfectant alcohol before use.

[0023] After the device is used up, the sliding docking sleeve 3 is moved by rotating the moving mechanism in the opposite direction, and the opening 13 is exposed, so that the removed cap 9 can be taken away.

[0024] Please refer to this carefully. Figure 2 The moving mechanism includes a screw 4 rotatably connected to the annular plate of the fixed docking sleeve 2. The screw 4 is threadedly connected to the annular plate of the sliding docking sleeve 3. A rotating handle 5 is fixedly connected to the end of the screw 4 away from the fixed docking sleeve 2.

[0025] In this embodiment: by rotating the rotating handle 5, the rotating handle 5 drives the screw 4 to rotate. Since the connection position between the sliding mating sleeve 3 and the screw 4 is eccentric, the rotating screw 4 can drive the sliding mating sleeve 3 to move axially.

[0026] Please refer to this carefully. Figure 3 and Figure 4 The hat-removing mechanism includes a fixed ear 8 fixedly connected to the annular plate of the fixed docking sleeve 2 and the sliding docking sleeve 3. A hat-removing plate 7 is rotatably installed on the lower inner side of the fixed ear 8. The hat-removing plate 7 has grooves 12 on both sides. One end of the inner wall of the groove 12 is integrally formed with a rotating shaft 10 that is rotatably connected to the fixed ear 8. A torsion spring 11 is engaged between the inner wall of the groove 12 and the fixed ear 8. A locking groove is provided at the contact position between the inner wall of the groove 12 and the inner side of the fixed ear 8 and the torsion spring 11, which engages with the end of the torsion spring 11.

[0027] In this embodiment: when the device is connected to one end of the pipe, during the process of the pipe entering, the cap removal plate 7 moves from its initial position (e.g., attached). Figure 3 As shown, the pipe rotates outward, at which point the torsion spring 11 twists. After the pipe end is misaligned with the cap removal plate 7, the cap removal plate 7 returns to its original position under the restoring force of the torsion spring 11. No cap removal operation is performed during this process. After the docking is completed, the two pipe ends move outward relative to the device. At this time, the cap removal plate 7 cannot rotate in the opposite direction. Under this squeezing force, the cap 9 separates from the pipe end.

[0028] Please refer to this carefully. Figure 3 The sealing ring 6 has a tapered surface that is wider on the outside and narrower on the inside at both ends. The outer diameter of the sealing cap 9 is equal to the inner diameter of the hollow column of the fixed docking sleeve 2 and the sliding docking sleeve 3.

[0029] In this embodiment, the conical design allows the sealing ring 6 to further reduce the moving resistance during the process of the pipe end entering and exiting the device, avoiding damage to the sealing ring 6 due to excessive resistance. At the same time, after the cap 9 is removed, the sealing ring 6 can effectively seal the pipe end.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
