Description

Technical Field

[0001] The utility model relates to the technical field of maintenance of gas pressure regulating facilities, and particularly relates to a predictive maintenance device for gas pressure regulating facilities. Background Technique

[0002] Gas pressure regulating facilities are key equipment for regulating and stabilizing the pressure of gas pipelines and play an important role in the gas transmission and distribution system. In actual operation, the downstream pressure often changes continuously due to changes in downstream gas consumption and upstream pressure, resulting in a sharp change in the operating state of gas pressure regulating facilities and greatly increasing the probability of their failure.

[0003] During the use of existing gas pressure regulating facilities, there is a lack of a fault monitoring device. When a gas pressure regulating facility fails, maintenance personnel cannot know the fault situation in the first time, and thus cannot carry out maintenance in time, which is likely to lead to gas pipeline accidents. Therefore, a predictive maintenance device for gas pressure regulating facilities is proposed to solve the above problems. Content of the Utility Model

[0008] The beneficial effects of the utility model are:

[0009] The predictive maintenance device for gas pressure regulating facilities is placed at both ends of the gas pressure regulating device. By rotating the worm gear, the worm gear is meshed with the transmission component, and then the gear cylinder is driven to rotate synchronously through the transmission component, thereby driving the internal thread cylinder to rotate synchronously. The force generated by the rotation of the thread causes the tensioning component to slide out through the sleeve, so that the tensioning components pass through the threaded holes in the flange to the other side. The tensioning component is moved to make the tensioning component stuck on one side of the flange. The worm gear is reversed, and then the tensioning component is reset through the transmission component, the gear cylinder and the internal thread cylinder, so that the columnar shell and the flange are tightened and the opposite side is tightly fitted. The device can be installed at the input and output ends of the gas pressure regulating device, and then the device is connected to the gas transmission pipe in the above manner. The pressure monitoring component monitors the gas pressure passing through the access pipe in real time. The pressure monitoring components on both sides of the gas pressure regulating device transmit the monitored data to the monitoring terminal, which has the advantages of real-time analysis and comparison. After a problem is found, the maintenance personnel can be informed of the fault situation at the first time, and then timely maintenance is performed.

[0010] On the basis of the above technical solution, the present invention can also be improved as follows.

[0011] Furthermore, the transmission assembly includes an inner gear ring and an outer worm wheel ring, the inner wall of the cylindrical shell is rotatably connected to the inner gear ring meshing with the gear cylinder, and the outer side of the inner gear ring is fixedly connected to the outer worm wheel ring meshing with the worm gear.

[0012] The beneficial effect of adopting the above further solution is that by rotating the worm gear, the worm gear is meshed with the outer worm wheel ring, and then the gear cylinder is driven to rotate synchronously through the inner gear ring, thereby driving the internal threaded cylinder to rotate synchronously.

[0013] Further, the tensioning assembly includes an external threaded plug, a rib rod, a clamping strip, a spring and a ball. The internal part of the internal threaded barrel is threadedly connected to the external threaded plug. One side of the external threaded plug is fixedly connected to a rib rod slidably connected to the sleeve. The end of the rib rod away from the external threaded plug is rotatably connected to the clamping strip. Springs are provided inside both ends of the clamping strip. Both ends of the spring are provided with a ball extending to the outside of the clamping strip.

[0014] Furthermore, a sealing gasket adapted to the flange is fixedly connected to the opposite side of the columnar shell.

[0015] The beneficial effect of adopting the above-mentioned further scheme is that the internal threaded cylinder rotates synchronously, and the force generated by the rotation of the thread drives the external threaded plug in the internal threaded cylinder to move, thereby driving the prism rod to slide out through the sleeve, so that the prism rod and the clamping strip both pass through the threaded hole in the flange to the other side, and the clamping strip is moved to make the clamping strip perpendicular to the prism rod. In this process, when the sphere separates from the prism rod, the spring restores its elastic deformation to prevent the prism rod from sliding in the sleeve and passing through the flange and affecting the operation due to the shaking of the clamping strip, so that the clamping strip can be stuck on one side of the flange, and the internal threaded cylinder is reversed, and the clamping strip can be driven by the external threaded plug and the prism rod to move toward the cylindrical shell, thereby tightening the cylindrical shell and the flange and making the opposite side fit tightly, and causing the sealing gasket on the opposite side to undergo elastic deformation and then seal.

[0016] Furthermore, the pressure monitoring component includes an air pressure sensor and a wireless transmission module. The top of the middle section of the access tube is provided with an air pressure sensor extending into the interior thereof, and the top of the air pressure sensor is provided with a wireless transmission module electrically connected thereto.

[0017] The beneficial effect of adopting the above further solution is that the air pressure sensor monitors the pressure of the gas passing through the access pipe, and the wireless transmission module transmits the monitored data to the monitoring terminal. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] In the embodiment, it is given by Figure 1-6 A predictive maintenance device for gas pressure regulating facilities. The present utility model includes a gas pressure regulating device 1 and an access pipe 2. Both ends of the gas pressure regulating device 1 and the access end of the gas transmission pipe are flanges 3. Both ends of the access pipe 2 are connected with columnar shells 4 that are flush with both ends and adapted to the flange 3. The opposite sides of the columnar shells 4 are fixedly connected with sleeves 5 that are distributed in an annular array and are internally connected and adapted to the threaded holes on the surface of the flange 3. Inside the columnar shells 4, there are rotatably connected internal thread cylinders 6 that are distributed in an annular array and are all adapted to the sleeves 5. The outer sides of the internal thread cylinders 6 are fixedly connected with gear cylinders 7. Inside the internal thread cylinders 6, there are tensioning assemblies 8 that are internally threaded and slidably connected to the sleeves 5. The inner walls of the columnar shells 4 are provided with transmission assemblies 9 that are all meshed with the gear cylinders 7. The tops of the columnar shells 4 are fixedly connected with rectangular housings 10 that are internally connected. The front side of the rectangular housing 10 is provided with a worm gear rod 11 that extends into its interior and is meshed with the transmission assembly 9. The middle section of the top of the access pipe 2 is provided with a pressure monitoring assembly 12 that extends into its interior;

[0027] The transmission assembly 9 includes an internal gear ring 901 and an external worm gear ring 902. The inner wall of the columnar shell 4 is rotatably connected with an internal gear ring 901 that is meshed with the gear cylinders 7. The outer side of the internal gear ring 901 is fixedly connected with an external worm gear ring 902 that is meshed with the worm gear rod 11;

[0028] By rotating the worm gear 11, the worm gear 11 meshes with the outer worm wheel ring 902, and then drives the gear cylinder 7 to rotate synchronously through the inner gear ring 901, thereby driving the inner thread cylinder 6 to rotate synchronously;

[0029] The tensioning assembly 8 includes an external threaded plug 801, a rib 802, a clamping strip 803, a spring 804 and a ball 805. The internal part of the internal threaded tube 6 is threadedly connected with the external threaded plug 801. One side of the external threaded plug 801 is fixedly connected with a rib 802 that is slidably connected with the sleeve 5. The end of the rib 802 away from the external threaded plug 801 is rotatably connected with the clamping strip 803. The two ends of the clamping strip 803 are provided with springs 804 inside, and the two ends of the spring 804 are provided with balls 805 extending to the outside of the clamping strip 803.

[0030] The opposite sides of the cylindrical shell 4 are fixedly connected with sealing gaskets 13 adapted to the flange 3;

[0031] The internal threaded barrel 6 rotates synchronously, and the force generated by the rotation of the thread drives the external threaded plug 801 in the internal threaded barrel 6 to move, thereby driving the ridge rod 802 to slide out through the sleeve 5, so that the ridge rod 802 and the clamping strip 803 both pass through the threaded hole in the flange 3 to the other side, and the clamping strip 803 is moved to make the clamping strip 803 perpendicular to the ridge rod 802. In this process, when the ball 805 is separated from the ridge rod 802, the spring 804 restores its elastic deformation to prevent the ridge rod 802 from sliding in the sleeve 5 and passing through the flange 3 due to the shaking of the clamping strip 803, so that the clamping strip 803 can be stuck on one side of the flange 3, and the internal threaded barrel 6 is reversed, and the clamping strip 803 can be driven by the external threaded plug 801 and the ridge rod 802 to move toward the cylindrical shell 4, so that the cylindrical shell 4 and the flange 3 are tightened and the opposite side thereof is tightly fitted, and the sealing gasket 13 on the opposite side is elastically deformed and then sealed;

[0032] The pressure monitoring assembly 12 includes an air pressure sensor 121 and a wireless transmission module 122. The top of the middle section of the access tube 2 is provided with an air pressure sensor 121 extending into the interior thereof, and the top of the air pressure sensor 121 is provided with a wireless transmission module 122 electrically connected thereto;

[0033] The air pressure sensor 121 monitors the pressure of the gas passing through the access pipe 2, and the wireless transmission module 122 transmits the monitored data to the monitoring terminal.

[0034] Working principle:

[0035] Step 1: Place the device at both ends of the gas pressure regulating device 1, and rotate the worm gear 11. Since the worm gear 11 is meshed with the outer worm wheel ring 902, the gear cylinder 7 is driven to rotate synchronously through the inner gear ring 901, thereby driving the inner thread cylinder 6 to rotate synchronously. The force generated by the rotation of the thread drives the outer thread plug 801 in the inner thread cylinder 6 to move, thereby driving the ridge rod 802 to slide out through the sleeve 5, so that the ridge rod 802 and the clamping strip 803 pass through the threaded hole in the flange 3 to the other side;

[0036] Step 2: Move the clamping strip 803 to make it perpendicular to the prism 802. During this process, when the ball 805 separates from the prism 802, the spring 804 restores its elastic deformation to prevent the prism 802 from sliding in the sleeve 5 and passing through the flange 3 due to the shaking of the clamping strip 803, so that the clamping strip 803 can be clamped on one side of the flange 3. The internal threaded tube 6 can be reversed by reversing the worm gear 11, and the clamping strip 803 can be driven to move toward the cylindrical shell 4 through the external threaded plug 801 and the prism 802, so that the cylindrical shell 4 and the flange 3 are tightened and the opposite side thereof is tightly fitted, and the sealing gasket 13 on the opposite side is elastically deformed and then sealed, and the device can be installed at the input and output ends of the gas pressure regulating device 1. The device can be connected to the flange 3 at one end of the gas transmission pipe in the above manner, and the device can be installed;

[0037] Step 3: The air pressure sensor 121 monitors the pressure of the gas passing through the access pipe 2, and the wireless transmission module 122 transmits the monitored data to the monitoring terminal. The wireless transmission modules 122 on both sides of the gas pressure regulating device 1 transmit the data monitored by the corresponding air pressure sensor 121 to the monitoring terminal, which is capable of real-time analysis and comparison. After a problem is found, the maintenance personnel can be aware of the fault situation in the first time and perform maintenance in time.
