Description

Technical Field

[0001] This utility model relates to the field of disassembly device technology, specifically a disassembly device for the lid of a natural gas pipeline filter kettle. Background Technology

[0002] In natural gas pipelines, metering skids are one of the important pieces of equipment in the natural gas pipeline transportation process. Their metering effect directly affects the company's economic benefits. In order to ensure the accurate metering and service life of the metering equipment, it is necessary to replace its pre-filter element regularly.

[0003] According to CN213738299U, a device for disassembling the lid of a natural gas pipeline filter kettle is disclosed. This technology discloses a device for disassembling the lid of a natural gas pipeline filter kettle, including a base and a lifting motor. The lifting motor consists of a motor base, a lifting conversion device, and a motor. A rotating shaft is welded to the upper surface of the base. A telescopic cylinder is connected to the inner wall of the rotating shaft through a bearing. A telescopic rod is inserted into one end of the telescopic cylinder. A snap-fit ​​hole is opened on the side of the telescopic rod. A support plate is welded to one end of the telescopic rod. The device has the following technical effects: "It can still transport the kettle lid to the ground when the device is placed below the ground, which increases the practicality and flexibility of the device. Through the combination of the second fixing plate, the snap-fit ​​shaft, and the screw, the screw can be screwed into the threaded hole of the kettle lid during use, avoiding the danger of the snap-fit ​​slipping off during transportation when the existing device uses a snap-fit ​​to fix the kettle lid, thus increasing the safety of the device when transporting the kettle lid."

[0004] In the existing solution, the threaded hole of the vessel lid is directly fixed with screws. However, in actual use, the vessel lid may not be firmly fixed due to uneven force or damage to the threaded hole, which poses a risk of slippage. In particular, after long-term use, the threaded hole may wear or deform, making it impossible for the screw to be fully tightened. In addition, when the vessel lid is heavy or vibration occurs during disassembly, the threaded connection alone is prone to loosening, and the screw is subjected to a large shear force, which poses a risk of breakage.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0027] Please see Figure 1 - Figure 6This utility model provides a technical solution: a natural gas pipeline filter kettle lid disassembly device, including a moving mechanism 1 for moving the device, and a fixing mechanism 2 for fixing the kettle lid on the moving mechanism 1. The fixing mechanism 2 includes:

[0028] The main component 21 includes a main frame 211 mounted on the moving mechanism 1. An internally threaded cylindrical seat 212 is fixed at the center of the upper end of the main frame 211. A circular plate 213 is rotatably mounted on the upper end of the internally threaded cylindrical seat 212. The circular plate 213 has several circumferentially distributed arc grooves 214 inside. Several circumferentially distributed sliders 215 are fixed on the upper end of the main frame 211. A slide rail 216 is slidably mounted on the sliders 215. A cam 217 is rotatably mounted on the upper end of the slide rail 216 and is located in the arc groove 214. A mounting bracket 218 is fixed on the lower end of the slide rail 216. A gripper 219 is mounted on the lower end of the cam 217.

[0029] Drive component 22 is mounted on main frame 211 and used to control the rotation of circular plate 213;

[0030] Adjustment component 23 is mounted on the moving mechanism 1 and is used to adjust the angle of the fixed main body component 21.

[0031] In this embodiment, when the circular plate 213 rotates, the cam 217 slides along the inside of the arc groove 214 through the arc groove 214. At the same time, the cam 217 drives the slide rail 216 to slide along the slider 215. The slider 215 drives the gripper 219 to move through the mounting bracket 218. By having multiple grippers 219 move radially in sync, the lid is ensured to be clamped evenly, avoiding damage from single-point force.

[0032] Specifically, the main component 21 also includes a knob screw 2110 that is threaded through and installed inside the internal threaded cylinder seat 212. A pressure plate 2111 is rotatably installed at the lower end of the knob screw 2110. Several guide rods 2112 distributed in a circle are fixed at the upper end of the pressure plate 2111 and are slidably installed through the main frame 211.

[0033] In this embodiment, after the lid is fixed by several clamps 219, the knob screw 2110 is rotated in conjunction with the guide rod 2112 to drive the pressure plate 2111 to press down the lid, further tightening the lid and preventing it from loosening during disassembly.

[0034] Specifically, the drive assembly 22 includes a shaft frame 221 fixed to the top outer edge of the main frame 211. A cylindrical rod 222 is rotatably installed inside the shaft frame 221. A threaded rod 223 is slidably installed through the cylindrical rod 222. The outer end of the threaded rod 223 is rotatably connected to the upper outer edge of the circular plate 213. An internally threaded bushing 224 is rotatably installed on the outer wall of the end of the cylindrical rod 222 and is threadedly connected to the threaded rod 223. A guide strip 225 is fixed on the inner wall of the cylindrical rod 222. A guide groove 226 is opened on the outer wall of the threaded rod 223 and cooperates with the guide strip 225.

[0035] In this embodiment, the threaded rod 223 is driven to extend and retract along the inside of the cylinder rod 222 by rotating the internal threaded bushing 224, thereby enabling the threaded rod 223 to drive the circular plate 213 to rotate.

[0036] Specifically, the adjustment component 23 includes a lower shaft seat 231 fixed to the upper end of the main frame 211, an upper shaft seat 232 rotatably mounted on the upper end of the lower shaft seat 231, and arc-shaped holes 233 are opened inside both ends of the upper shaft seat 232.

[0037] In this embodiment, the main body component 21 can be adjusted by 90° through the lower bearing 231, and the lower bearing 231 and the upper bearing 232 are fixed by bolts and nuts to adapt to the lid of the filter vessel installed horizontally or vertically.

[0038] Specifically, the moving mechanism 1 includes a frame 12 fixed at the upper end of the trolley 11, a slide 13 slidably mounted on the frame 12, a manual hydraulic cylinder 14 fixed at the lower end inside the trolley 11, a sprocket 15 rotatably mounted at the output end of the manual hydraulic cylinder 14, and a chain 16 connecting the rear end of the frame 12 and the rear end of the slide 13, with the chain 16 cooperating with the sprocket 15.

[0039] In this embodiment, the manual hydraulic cylinder 14 drives the sprocket 15 in conjunction with the chain 16 to drive the fixing mechanism 2 on the slide 13 to adjust the height, which is labor-saving and adaptable to different heights of the kettle lid.

[0040] Specifically, the moving mechanism 1 also includes guide wheels 17 installed on both sides of the top rear end and the bottom rear end of the carriage 13, and the guide wheels 17 cooperate with the upright frame 12.

[0041] In this embodiment, the guide wheel 17 reduces the friction between the carriage 13 and the upright frame 12, making the lifting and lowering smoother and extending the service life of the components.

[0042] The working principle and usage process of this utility model are as follows: First, the main component 21 can be adjusted by 90° through the lower shaft seat 231, and the lower shaft seat 231 and the upper shaft seat 232 can be fixed by bolts and nuts to adapt to the lid of the filter vessel installed horizontally or vertically.

[0043] Then, the sprocket 15 is driven by the manual hydraulic cylinder 14 in conjunction with the chain 16 to drive the fixing mechanism 2 on the carriage 13 to adjust the height;

[0044] Finally, the fixed mechanism 2 on the moving mechanism 1 is brought into contact with the lid of the natural gas pipeline filter vessel. Then, the internal threaded bushing 224 is rotated to drive the threaded rod 223 to move telescopically along the inside of the cylinder rod 222. This allows the threaded rod 223 to drive the circular plate 213 to rotate. When the circular plate 213 rotates, it drives the cam 217 to slide along the inside of the arc groove 214 through the arc groove 214. At the same time, the cam 217 drives the slide rail 216 to slide along the slider 215. The slider 215 drives the gripper 219 to move through the mounting bracket 218. By having multiple grippers 219 move radially in sync, the lid is ensured to be clamped evenly, avoiding damage from single-point force.
