Description
Technical Field
[0001] This utility model relates to the field of maintenance technology for gasification station parts, and more specifically, to a lifting and positioning device for maintenance of LNG gasification station parts. Background Technology
[0002] An LNG regasification station is a gas supply facility that receives, stores, and regasifies liquefied natural gas (LNG). It is divided into two categories: single-point direct supply regasification stations and LNG satellite stations. The core process includes unloading and pressurization, storage tank self-pressurization, and ambient temperature regasification. It is mainly used to supplement the gas source and meet the peak demand of cities with natural gas shortages. As a key hub for natural gas supply, the pipeline system of an LNG regasification station (including key components such as safety valves, flow meters, and pressure gauges) needs to be regularly calibrated, replaced, or repaired to ensure the safe and stable operation of the gas supply system. Currently, the industry mainly relies on two methods for maintenance work on pipelines and auxiliary equipment of LNG gasification stations: manual scaffolding or general-purpose cranes. However, LNG gasification station pipelines are mostly arranged at a height of 2-5m. Manual scaffolding requires professional personnel, takes a long time to set up, and is inconvenient to move. In addition, scaffolding requires a large space, making it impossible to set up in areas with dense pipelines. If using the boom of a general-purpose crane, the crane is too large, and the passages inside the LNG gasification station are narrow and there are many obstacles (such as fire hydrants, cable trenches, and equipment foundations), making it impossible for the crane to get close to the maintenance point. It also has poor adaptability to the site environment and cannot carry out effective operations. Therefore, a lifting and positioning device for the maintenance of LNG gasification station accessories is proposed. Utility Model Content

A connecting block 11 is fixedly connected to the top of the rod 9. A connecting seat 12 is provided on the outside of the connecting block 11. The support rod 13 is rotatably connected to the rod 9 through the connecting block 11 and the connecting seat 12. A support rod 13 is fixedly connected to one side of the connecting seat 12. A fixing plate 14 is fixedly connected to one end of the support rod 13. The second fixed seat 20 and the first fixed seat 18 are respectively fixedly connected to the middle part of the support rod 13 and the insertion rod 9. An electric push rod 19 is rotatably connected to one side of the first fixed seat 18. By activating the electric push rod 19 to push the second fixed seat 20, the support rod 13 can drive the connecting seat 12 to rotate, thereby adjusting the tilt angle of the support rod 13. A hanging wheel 15 is rotatably connected to the middle of the fixed plate 14. A chain 16 is inserted into the middle of the hanging wheel 15. One end of the chain 16 is connected to a scraper hook 17. By passing one end of the chain 16 around the gasification station pipeline and connecting it to the scraper hook 17, it is convenient to suspend and maintain the operation. In conjunction with the activation of the hydraulic telescopic rod 6, the support rod 13 is controlled to drive the scraper hook 17 to rise and fall in sequence, which is convenient for inspection and maintenance.
[0017] As attached Figure 1-3 As shown, the top of the step ladder 3 is located on the side of the operating platform 2 away from the hydraulic telescopic rod 6. The stabilizing clamp 7 is fixed to one side of the operating platform 2. The toolbox 5 is located at the bottom of the operating platform 2. The second support ring 10 is located on top of the first support ring 8. A ball groove is provided between the second support ring 10 and the first support ring 8. A ball is provided in the middle of the ball groove. The step ladder 3 facilitates personnel to go up to the top of the operating platform 2 for maintenance operations. The stabilizing clamp 7 improves the stability of the hydraulic telescopic rod 6. The cooperation of the ball groove and the ball can improve the stability of the insertion rod 9 and the second support ring 10 rotating on the top of the hydraulic telescopic rod 6 and the first support ring 8. It is convenient to move the scraper hook 17 and the hanging wheel 15 to the designated position for easy positioning and use, thereby adjusting the lifting position.
[0018] As attached Figure 1-3 As shown, the cross-sectional shape of the connecting seat 12, the first fixed seat 18, and the second fixed seat 20 are all set to "U" shape. The connecting seat 12 is rotatably connected to the connecting block 11. The first fixed seat 18 is fixed to the top of the insert rod 9, and the second fixed seat 20 is fixed to the middle of the support rod 13. The moving end of the electric push rod 19 is rotatably connected to one side of the second fixed seat 20. A controller is provided on one side of the operating table 2. The controller is electrically connected to the electric push rod 19. By starting the electric push rod 19, the support rod 13 can be rotated, and the pitch angle of the support rod 13 can be adjusted. The controller can be used for convenient operation. It is worth noting that both the electric push rod 19 and the hydraulic telescopic rod 6 are existing technologies and will not be discussed further.
[0019] The working principle of this utility model is as follows: When in use, the base 1 is pushed to move the operating platform 2 and the hydraulic telescopic rod 6 to the pipeline of the gasification station that needs to be inspected through the universal brake wheel 4. The step ladder 3 makes it convenient for maintenance personnel to stand on the operating platform 2 to carry out high-altitude maintenance. The toolbox 5 is convenient for storing maintenance tools. By connecting the chain 16 around the pipe and the scraper hook 17, the scraper hook 17 and the chain 16 are fixedly connected to the pipe. At this time, the hydraulic telescopic rod 6 is activated to control the insertion rod 9 to drive the support rod 13 to rise and fall. The pipe can be raised and lowered through the hanging wheel 15, the chain 16, and the scraper hook 17, which facilitates the disassembly and removal of the pipe support and makes it convenient for maintenance. By activating the electric push rod 19, the support rod 13 is controlled to rotate through the connecting seat 12, which can adjust the tilt angle of the support rod 13. By pushing the support rod 13, the insertion rod 9 is driven to rotate on the top of the hydraulic telescopic rod 6, which can adjust the position of the chain 16 and the scraper hook 17, making it convenient for horizontal rotation adjustment and positioning the chain 16 and the scraper hook 17 at the location where the pipeline needs maintenance, thus achieving precise positioning.
