Description

Technical Field

[0001] This utility model belongs to the technical field of pipeline cleaning, and in particular relates to a gas venting valve cleaning device. Background Technology

[0002] In the process of gas production, the vent valve on the pipeline is an important pressure relief device. During maintenance or emergencies, it needs to be vented, opening the vent valve. For ease of maintenance, companies typically install flanged connecting pipes near the vent valve. However, traditional cleaning methods have the following drawbacks: First, low efficiency: When the vent valve is open, manual cleaning of the vent valve port is required via the flanged connecting pipe to reduce debris and improve airtightness. The vent valve uses a combination of soft and hard seals, making manual cleaning cumbersome. Second, residual gas may leak from the valve port, posing a safety hazard to personnel cleaning the port. Third, low adjustment capability of the cleaning structure: Existing methods, such as the cleaning device for the vent valve port (patent number CN202421831615.4), suffer from positioning difficulties and low adjustment capability due to the single vertical vibration mode, resulting in low cleaning efficiency. Fourth, insufficient automation, requiring manual intervention for most adjustments.

[0003] Therefore, a cleaning device is needed that can efficiently clean the valve port of the vent valve, thereby reducing the labor intensity of the workers and ensuring their personal safety. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figure 1-9 A gas venting valve cleaning device includes a walking base 1, a lifting mechanism 2, and a hydraulic cylinder 3. The walking base 1 includes a square base body 101, which is equipped with a control terminal to control the operation of the device. The lifting mechanism 2 is located on the upper part of the walking base 1. The hydraulic cylinder 3 is located on the upper part of the lifting mechanism 2, and the hydraulic cylinder 3 is connected to an ultrasonic vibrating head 5 through a universal joint system 4. This utility model allows operators to remotely control a walking base 1 to move to the vicinity of the flange connection pipe 601 of the vent valve 7. Upon arrival, the lifting mechanism raises the hydraulic cylinder 3 to a height sufficient to enter the flange connection pipe 601. Then, the extension rod 301 of the hydraulic cylinder 3 extends, allowing the ultrasonic vibrating head 5 to enter the vicinity of the vent valve 7 in the pipeline 6 through the flange connection pipe 601. The ultrasonic vibrating head 5 then emits ultrasonic waves for cleaning. During the cleaning process, the universal joint system 4 can be controlled to adjust the rotation angle, the extension rod 301 of the hydraulic cylinder 3 can be extended to adjust the lateral distance within the pipeline, and the lifting mechanism 2 can be raised and lowered to adjust the vertical and height distance within the pipeline. The coordination of these three mechanisms allows the ultrasonic vibrating head 5 to clean different positions of the vent valve 7 and achieve the best cleaning effect. Figure 1 As shown.

[0030] The base body 101 is symmetrically provided with four walking wheels 102. Each walking wheel 102 moves independently. The different speed vectors between the four walking wheels 102 are combined to enable the present invention to move in different directions.

[0031] The lifting mechanism 2 according to claim 1 comprises two supporting platforms arranged symmetrically up and down, and a scissor hinge mechanism arranged between the two supporting platforms; both of the two supporting platforms are symmetrically provided with two sliding grooves in front and rear; the lower supporting platform is fixed on the upper surface of the base body. The two groups of upper scissor hinge mechanisms are slidingly connected in the two sliding grooves of the upper supporting platform through rotating shafts; the two groups of lower scissor hinge mechanisms are slidingly connected in the two sliding grooves of the lower supporting platform through rotating shafts, and a U-shaped sliding block is fixed at the lower part of the scissor hinge mechanism through a rotating shaft; a threaded hole is opened in the middle of the sliding block, and a screw rod matched with the threaded hole is arranged therein, the screw rod is rotationally connected to the lower supporting platform, and the other end of the screw rod is connected with a rotating motor; the rotating motor is fixed on the lower supporting platform, and the output shaft of the rotating motor is connected with the screw rod. When the screw rod rotates forward and backward, the sliding block moves left and right, which then drives the entire scissor hinge mechanism to expand or contract. The sliding grooves cooperate with the upper part and the lower part of the scissor hinge mechanism to change the distance between the two supporting platforms, thereby realizing the height adjustment of the ultrasonic vibrating head, and the screw thread has good self-locking performance, so that the vertical position and height will not change automatically after adjustment is completed.

[0032] The hydraulic cylinder is fixed on the upper surface of the upper supporting platform, the top end of the telescopic rod of the hydraulic cylinder is fixedly connected with one end of the universal joint system, and the other end of the universal joint system is connected with the ultrasonic vibrating head. The telescopic rod of the hydraulic cylinder expands and contracts to adjust the lateral distance in the pipeline.

[0033] The universal joint system comprises an I-shaped block located in the middle, and a first U-shaped block and a second U-shaped block symmetrically arranged at the left and right ends of the I-shaped block; two identical U-shaped connectors are symmetrically arranged on the left and right sides of the I-shaped block, the first U-shaped block and the second U-shaped block have the same structure, both are cylindrical, and a U-shaped connector is arranged at the top of each of the first U-shaped block and the second U-shaped block; a dual-shaft motor is vertically fixed in the U-shaped connector of the first U-shaped block, the output shaft of the dual-shaft motor is fixedly connected with one U-shaped connector of the I-shaped block, another dual-shaft motor is horizontally fixed in the other U-shaped connector of the I-shaped block, the output shaft of the dual-shaft motor is fixedly connected with the U-shaped connector of the second U-shaped block, and the central axes of the output shafts of the two dual-shaft motors are perpendicular to each other. The outer width of the U-shaped connectors of the first U-shaped block and the second U-shaped block is d, the inner width of the U-shaped connector of the I-shaped block is D, and d < D; the inner width of the U-shaped connectors of the first U-shaped block and the second U-shaped block is l, the outer width of the U-shaped connector of the I-shaped block is L, and l < L, as Figure 8 and Figure 9 As shown. When the vertical dual-axis motor 404 inside unit U-A 402 is started, it rotates forward and backward. Its output shaft 405 is fixed to a U-shaped connector of unit I 401, allowing unit I 401 to rotate left and right around the central axis of output shaft 405, thus causing the ultrasonic vibrating head 5 to rotate left and right. When the horizontal dual-axis motor 404 inside unit I 401 is started, it rotates forward and backward. Its output shaft 405 is fixed to a U-shaped connector of unit U-B 403, allowing unit U-B 403 to rotate up and down around the central axis of output shaft 405, thus causing the ultrasonic vibrating head 5 to rotate up and down. The three components of the universal joint system 4, U-shaped component 401, U-shaped component A 402, and U-shaped component B 403, work together with the dual-axis motor 404 to rotate, allowing the ultrasonic vibrating head 5 to have different angles. The ratio of the inner width to the outer width of the two sets, as well as the arrangement of the three components with the output shaft 405 of the dual-axis motor 404, ensure that the three components do not interfere with each other during the rotation adjustment process. Ultimately, the ultrasonic vibrating head 5 can have different angles in the pipeline to face the various parts of the cleaning vent valve 7, achieving the best cleaning effect.

[0034] Preferably, the ultrasonic vibrating head 5 is cylindrical, and both its non-connected side and side surface can emit vibrating ultrasonic waves, with adjustable ultrasonic wave amplitude to improve cleaning efficiency. The ultrasonic vibrating head 5 has a lighting device and a camera 8 in its center for worker observation; if the lighting device and camera 8 are obscured by dust or ash, the worker can use the universal joint system to control the ultrasonic vibrating head 5 to perform a wrist-swinging motion to remove the dust or ash.

[0035] Working process: After installing all components of this utility model, the operator starts the walking base 1 via the control terminal. The four independent walking wheels 102 move in any direction according to the velocity vector synthesis until the device reaches the front of the flange connection pipe 601 of the vent valve 7. The rotary motor 201 is started, and the lead screw 202 rotates forward and backward, driving the slider 203 to move left and right, which drives the scissor hinge mechanism 205 to open or close, so that the upper support platform 206 rises to the height where the ultrasonic vibrator 5 can extend into the flange connection pipe. The telescopic rod 301 of the hydraulic cylinder 3 extends, pushing the universal joint system 4 and the ultrasonic vibrator 5 through the flange connection pipe into the pipeline until the vibrator reaches the vicinity of the vent valve. The universal joint system activates the vertical dual-axis motor 404 within U-byte A 402, allowing A-byte 401 to rotate left and right around the central axis of output shaft 405, thus rotating the ultrasonic vibrating head 5 left and right. Simultaneously, the horizontal dual-axis motor 404 within A-byte 401 activates, allowing U-byte B 403 to rotate up and down around the central axis of output shaft 405, thus rotating the ultrasonic vibrating head 5 up and down. Ensure the end face or side surface of the ultrasonic vibrating head 5 is directly facing the valve port to be cleaned. The ultrasonic vibrating head 5 is activated, and the ultrasonic vibration wave size is adjusted as needed, emitted simultaneously from the end face and side surface to clean debris from the valve port. Built-in lighting and a camera 8 transmit images to the control terminal in real time, allowing staff to observe the cleaning effect. If incomplete cleaning is found in certain areas, the extension of the telescopic rod or the universal joint angle can be fine-tuned via the control terminal for precise re-cleaning. After cleaning, the extension rod 301 of the hydraulic cylinder 3 retracts, causing the ultrasonic vibrating head 5 to exit the flange connection pipe 601; the rotary motor 201 reverses, and the lifting mechanism 2 descends to its retracted state. Once the walking base 1 moves to the designated position, the equipment enters standby mode, awaiting the next work instruction.
