Description

Technical Field

[0001] The utility model relates to the technical field of pipeline detection equipment, in particular to an installation and calibration device for pipeline detection inertial navigation equipment. Background Art

[0002] Pipeline inspection inertial navigation devices are often used for positioning and navigation inside pipelines to help achieve pipeline inspection, maintenance, and repair. These devices usually contain inertial sensors, such as gyroscopes and accelerometers, to measure the position, speed, and direction of the device inside the pipeline. With the data provided by these sensors, pipeline operators can accurately understand the location and status of the pipeline and take appropriate actions.

[0003] Pipeline inspection requires high-precision positioning and navigation to ensure accurate detection and operation of the inside of the pipeline. Inertial navigation system is a common technology for achieving internal positioning and navigation in pipelines, but its accuracy is affected by many factors. Therefore, a pipeline inspection inertial navigation device is needed to install a calibration device to improve its accuracy and reliability. Utility Model Content

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A mounting and calibration device for pipeline detection inertial navigation equipment comprises a frame, transverse adjustment mechanisms are plugged into both sides of the frame, longitudinal adjustment mechanisms are plugged into the top and bottom of the frame, a pipeline is fixedly mounted on the frame via the transverse adjustment mechanism and the longitudinal adjustment mechanism, a clamping mechanism is fixedly mounted at one end inside the transverse adjustment mechanism and the longitudinal adjustment mechanism, the transverse adjustment mechanism comprises a lead screw; the clamping mechanism comprises a base plate; and the longitudinal adjustment mechanism comprises a screw.

[0006] A further improvement of the technical solution of the utility model is that a first nut is fixedly installed at one end of the screw rod, and the other end of the screw rod passes through the pipeline and is rotatably connected to a first turntable, and a sliding rod is fixedly installed at one side of the first turntable.

[0007] A further improvement of the technical solution of the utility model is that: the sliding rod passes through the frame and the pipeline.

[0008] A further improvement of the technical solution of the utility model is that: the clamping mechanism is fixedly installed on one side of the first rotating disk.

[0009] A further improvement of the technical solution of the utility model is that a tooth groove is provided inside one side of the base plate, the base plate is frictionally inserted into a limit plate through the tooth groove, and a clamping plate is fixedly installed on one side of the limit plate.

[0010] A further improvement of the technical solution of the utility model is that: the clamping mechanism is provided with four groups, which are fixedly installed on one end of the lateral adjustment mechanism and the longitudinal adjustment mechanism through a base plate.

[0011] A further improvement of the technical solution of the utility model is that a second nut is fixedly installed at one end of the screw rod, a second turntable is rotatably installed at the bottom of the screw rod, and a positioning rod is fixedly installed at one side of the second turntable.

[0012] A further improvement of the technical solution of the utility model is that the positioning rod and the screw rod penetrate the frame and the pipeline.

[0013] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0014] The utility model provides an installation and calibration device for an inertial navigation device for pipeline detection. The inertial navigation device for pipeline detection is located between a transverse adjustment mechanism and a longitudinal adjustment mechanism in a pipeline. The transverse movement calibration of the inertial navigation device for pipeline detection is completed by the transverse adjustment mechanism. A first nut is rotated by a tool to drive a screw rod to rotate, so that the screw rod can move horizontally on the pipeline and the frame, thereby pushing a first rotating disk connected in rotation to move horizontally, and a clamping mechanism for contacting and clamping the inertial navigation device for pipeline detection is installed on one side of the first rotating disk, so that the clamping mechanism is pushed to move by the transverse adjustment mechanism, and the transverse position of the inertial navigation device for pipeline detection is moved and calibrated.

[0015] The utility model provides an installation and calibration device for pipeline detection inertial navigation equipment. A clamping mechanism is installed at one end of a transverse adjustment mechanism and a longitudinal adjustment mechanism. When the transverse adjustment mechanism clamps the pipeline detection inertial navigation equipment through the clamping mechanism, the longitudinal adjustment mechanism can still adjust the height of the pipeline detection inertial navigation equipment. During this period, the transverse position of the pipeline detection inertial navigation equipment remains unchanged. When the longitudinal adjustment mechanism pushes the pipeline detection inertial navigation equipment downward, a clamping plate is inserted into a tooth groove of a base plate through a limiting plate, so that the clamping plate can be moved up and down with the pipeline detection inertial navigation equipment for calibration, but cannot be moved laterally. Because of the arrangement of the tooth groove, the friction resistance between the clamping plate and the tooth groove is relatively large. When the longitudinal adjustment mechanism does not adjust the height of the pipeline detection inertial navigation equipment, the friction force can support the gravity of the pipeline detection inertial navigation equipment, so that the pipeline detection inertial navigation equipment will not slide down naturally.

[0016] The utility model provides an installation and calibration device for an inertial navigation device for pipeline detection. The second nut is rotated by a tool to drive the screw rod to rotate, and the second turntable is pushed to move up and down, thereby driving the upper and lower clamping mechanisms to adjust the height, and the pipeline detection inertial navigation device that has been calibrated horizontally is pushed and calibrated vertically. The internal environment of the pipeline is complex, including factors such as curvature, slope, and material. These factors will affect the accuracy of the inertial navigation system. The installation and calibration device for the pipeline detection inertial navigation device is used to cope with these environmental restrictions, ensuring that the navigation system can provide accurate positioning and navigation information under various conditions.

DETAILED DESCRIPTION

[0023] The present invention is further described in detail below in conjunction with the embodiments:

[0024] like Figure 1-2 As shown, the utility model provides an installation and calibration device for pipeline detection inertial navigation equipment, including a frame 1, with lateral adjustment mechanisms 3 inserted on both sides of the frame 1, and longitudinal adjustment mechanisms 5 inserted on the top and bottom of the frame 1. The frame 1 is fixedly installed with a pipeline 2 through the lateral adjustment mechanism 3 and the longitudinal adjustment mechanism 5, and a clamping mechanism 4 is fixedly installed at one end inside the lateral adjustment mechanism 3 and the longitudinal adjustment mechanism 5.

[0025] like Figure 3As shown, the utility model provides a technical solution: preferably, the lateral adjustment mechanism 3 includes a screw rod 32, one end of the screw rod 32 is fixedly installed with a first nut 33, the other end of the screw rod 32 passes through the pipe 2 and is rotatably plugged into a first turntable 34, one side of the first turntable 34 is fixedly installed with a slide rod 31, the slide rod 31 passes through the frame 1 and the pipe 2, and the clamping mechanism 4 is fixedly installed on one side of the first turntable 34.

[0026] In this embodiment, the pipeline detection inertial navigation device is located between the transverse adjustment mechanism 3 and the longitudinal adjustment mechanism 5 in the pipeline 2. The transverse movement calibration of the pipeline detection inertial navigation device is completed by the transverse adjustment mechanism 3. The first nut 33 is rotated by a tool to drive the screw rod 32 to rotate, so that the screw rod 32 can move horizontally on the pipeline 2 and the frame 1, thereby pushing the first turntable 34 connected in rotation to move horizontally, and the clamping mechanism 4 for contacting and clamping the pipeline detection inertial navigation device is installed on one side of the first turntable 34, so that the clamping mechanism 4 is pushed to move by the transverse adjustment mechanism 3, and the transverse position of the pipeline detection inertial navigation device is moved and calibrated.

[0027] like Figure 4 As shown, the utility model provides a technical solution: preferably, the clamping mechanism 4 includes a base plate 41, a tooth groove 42 is opened inside one side of the base plate 41, the base plate 41 is frictionally inserted into a limit plate 43 through the tooth groove 42, and a clamping plate 44 is fixedly installed on one side of the limit plate 43. The clamping mechanism 4 is provided with four groups, which are fixedly installed at one end of the lateral adjustment mechanism 3 and the longitudinal adjustment mechanism 5 through the base plate 41.

[0028] In this embodiment, the clamping mechanism 4 is installed at one end inside the lateral adjustment mechanism 3 and the longitudinal adjustment mechanism 5. When the lateral adjustment mechanism 3 clamps the pipeline detection inertial navigation device through the clamping mechanism 4, the longitudinal adjustment mechanism 5 can still adjust the height of the pipeline detection inertial navigation device. During this period, the lateral position of the pipeline detection inertial navigation device remains unchanged. When the longitudinal adjustment mechanism 5 presses down to push the pipeline detection inertial navigation device, the clamping plate 44 is inserted into the tooth groove 42 of the base plate 41 through the limit plate 43, so that the clamping plate 44 can be calibrated up and down with the pipeline detection inertial navigation device, but cannot move laterally. Because of the provision of the tooth groove 42, the friction resistance between the clamping plate 44 and the tooth groove 42 is relatively large. When the longitudinal adjustment mechanism 5 does not adjust the height of the pipeline detection inertial navigation device, the friction force can support the gravity of the pipeline detection inertial navigation device, so that it will not slide down naturally.

[0029] like Figure 5As shown, the utility model provides a technical solution: preferably, the longitudinal adjustment mechanism 5 includes a screw rod 53, a second nut 52 is fixedly installed at one end of the screw rod 53, a second turntable 54 is rotatably installed at the bottom of the screw rod 53, a positioning rod 51 is fixedly installed on one side of the second turntable 54, and the positioning rod 51 and the screw rod 53 pass through the frame 1 and the pipe 2.

[0030] In this embodiment, the second nut 52 is rotated by a tool to drive the screw rod 53 to rotate, and the second turntable 54 is pushed up and down, thereby driving the upper and lower clamping mechanisms 4 to adjust the height, and the pipeline detection inertial navigation device that has been calibrated horizontally is pushed and calibrated vertically. The internal environment of the pipeline is complex, including factors such as curvature, slope, and material. These factors will affect the accuracy of the inertial navigation system. The pipeline detection inertial navigation device is used to install a calibration device to cope with these environmental restrictions, ensuring that the navigation system can provide accurate positioning and navigation information under various conditions.

[0031] The working principle of the installation and calibration device for pipeline detection inertial navigation equipment is described in detail below.

[0032] like Figure 1-5As shown, the pipeline detection inertial navigation device is located between the transverse adjustment mechanism 3 and the longitudinal adjustment mechanism 5 in the pipeline 2. The transverse movement calibration of the pipeline detection inertial navigation device is completed by the transverse adjustment mechanism 3. The first nut 33 is rotated by a tool to drive the screw rod 32 to rotate, so that the screw rod 32 can move horizontally on the pipeline 2 and the frame 1, thereby pushing the first rotating disk 34 connected to the rotation to move horizontally, and the clamping mechanism 4 used for contacting and clamping the pipeline detection inertial navigation device is installed on one side of the first rotating disk 34, so that the transverse adjustment mechanism 3 is used to push the clamping mechanism 4 to move, and the transverse position of the pipeline detection inertial navigation device is moved and calibrated. The clamping mechanism 4 is installed at one end of the transverse adjustment mechanism 3 and the longitudinal adjustment mechanism 5. After the transverse adjustment mechanism 3 clamps the pipeline detection inertial navigation device through the clamping mechanism 4, the longitudinal adjustment mechanism 5 can still adjust the height of the pipeline detection inertial navigation device. During this period, the transverse position of the pipeline detection inertial navigation device remains unchanged, and the longitudinal adjustment mechanism 5 pushes the pipeline detection inertial navigation device downward. When measuring the inertial navigation device, the clamping plate 44 is inserted into the tooth groove 42 of the base plate 41 through the limit plate 43, so that the clamping plate 44 can be moved up and down for calibration with the pipeline detection inertial navigation device, but cannot be moved laterally. Because of the setting of the tooth groove 42, the friction resistance between the clamping plate 44 and the tooth groove 42 is relatively large. When the longitudinal adjustment mechanism 5 does not adjust the height of the pipeline detection inertial navigation device, the friction force can support the gravity of the pipeline detection inertial navigation device, so that it will not slide down naturally. The second nut 52 is rotated by a tool to drive the screw 53 to rotate, and the second turntable 54 is pushed up and down, thereby driving the upper and lower clamping mechanisms 4 to adjust the height, and the pipeline detection inertial navigation device that has been calibrated laterally is pushed longitudinally for calibration. The internal environment of the pipeline is complex, including factors such as curvature, slope, and material. These factors will affect the accuracy of the inertial navigation system. The pipeline detection inertial navigation device is used to install a calibration device to cope with these environmental restrictions, ensuring that the navigation system can provide accurate positioning and navigation information under various conditions.

[0033] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
