Technical Field

[0001] The utility model relates to the technical field of pipeline hangers, in particular to a stable and reliable natural gas pipeline hanger. Background Art

[0002] Natural gas pipelines are pipeline systems used to transport natural gas, and they play a vital role in the natural gas supply chain. As a clean and efficient energy source, natural gas is widely used in residential life, industrial production, power generation and other fields, and natural gas pipelines are the key channels for transporting natural gas from the production area to the users.

[0003] At present, during the pipe laying process at natural gas construction sites, construction parties usually use slings to lift the pipes. On the one hand, the slings are prone to wear and tear. On the other hand, during the pipe lifting process, the pipes are unstable and prone to swing and fall off, causing injuries to personnel and damage to the pipes. Utility Model Content

[0004] In order to solve the technical problem that the natural gas pipeline is unstable and easy to swing and fall off during the process of hanging the natural gas pipeline, the utility model provides a stable and reliable natural gas pipeline hanger.

[0005] The utility model adopts the following technical scheme to achieve: a stable and reliable natural gas pipeline hanger.

[0006] It comprises a shell, one end of which is provided with a hook, a slot for an active rotating rod to pass through is opened on the shell, and a motor is provided at one end of the active rotating rod passing through the slot, and a side plate is provided at the other end of the active rotating rod through a bearing, and the side plate can be used to place the motor;

[0007] The clamping mechanism comprises a movable groove 1, a gripping clamp and a gripping driving unit. The movable groove 1 is provided at the other end of the housing. The gripping clamp completes the pipe gripping work through the gripping driving unit arranged in the movable groove 1.

[0008] A locking mechanism is provided on the gripping clamp.

[0009] Through the above technical solution, the motor can drive the active rotating rod to rotate, so that multiple rotating gears rotate and multiple grippers perform clamping work. In addition, multiple grippers are arranged at equal distances on the active rotating rod to enhance the stability of pipe clamping.

[0010] The pipeline can be limited again by the locking mechanism, thereby ensuring the stability of pipeline lifting.

[0011] As a further improvement of the above scheme, the clamping drive unit includes a rotating gear, a driven gear, a driven rotating rod, a grab clamp and a hinged rod. The rotating gear is fixed on the active rotating rod and is located in the movable groove one. The rotating gear is meshingly connected with one of the driven gears. Both ends of the two driven rotating rods are arranged in the movable groove one through bearings. The two driven gears are fixed on the driven rotating rod and are meshingly connected with each other. The driven rotating rod and the grab clamp are hingedly connected. One end of the two hinged rods is hinged in the movable groove one, and the other end of the hinged rod is hinged on the grab clamp.

[0012] Through the above technical solution, a motor is set to drive multiple grippers to operate, which saves costs and can stably lift the pipeline, making it suitable for wide use.

[0013] As a further improvement of the above solution, a rubber pad is provided on one side adjacent to the two gripping clamps, and anti-slip grooves are provided on the rubber pad.

[0014] Through the above technical solution, the rubber pad can enhance the friction between the gripper and the pipe, so that the gripper can stably clamp and move the pipe.

[0015] As a further improvement of the above scheme, the locking mechanism includes a fixed box, a contraction groove, an extension groove, a round rod, a skateboard, a skateboard groove, a fixed plate, a rope, a buckle, a limit block, a buckle groove, a slot, a movable groove II, a tension spring and a pull rod. The fixed box is arranged on one of the clamps, and the contraction groove is opened in the fixed box, the extension groove is opened on the contraction groove and forms a channel for the rope to pass through with the contraction groove, the two skateboard grooves are both opened in the contraction groove, and the skateboard slides on the skateboard groove, both ends of the round rod are fixed to the skateboard, and a groove for the round rod to pass through is opened on the fixed plate, the two fixed plates are both fixed in the contraction groove, one end of the rope is fixed to the round rod, and the other end of the rope is fixed with a buckle, a spring is welded on the fixed plate, and the middle part of the spring is wrapped around the round rod, and the end of the spring away from the fixed plate is welded to the skateboard.

[0016] According to the above technical solution, by setting one end of the rope to be retractable, the other end of the buckle can be free of force. Under the action of the spring wound on the round rod, the round rod can be driven to rotate back to the initial position, and the rope can be rewound on the round rod. The storage of the rope does not affect the pipe feeding. In addition, the slide plate rolls on the slide plate groove to ensure the stability of the round rod.

[0017] As a further improvement of the above solution, the limit block is arranged on another grabbing clamp, and the buckle slot is opened on the limit block, the movable slot 2 is also opened on the limit block and connected with the buckle slot, and the slot is opened on the buckle.

[0018] Through the above technical solution, a buckle groove for inserting a buckle is provided on the other gripping clamp, so that the rope belt can be wound around the pipe and the gripping clamp to limit the pipe in a circle, thereby effectively preventing the pipe from falling off the gripping clamp and causing the pipe to fall.

[0019] As a further improvement of the above solution, one end of the two tension springs is welded to the limit block, and the other end of the two tension springs is welded with a pull rod, and the pull rod passes through the second movable groove and is inserted into the buckle groove.

[0020] Through the above technical solution, the position of the buckle can be locked by setting the pull rod, and then a stable structure is formed between the round hook extending from one side of the slot and the gripper. And under the elasticity of the tension spring, the pull rod can be prevented from being lost, and the insertion of the buckle is also convenient, which saves the insertion efficiency.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] The utility model can clamp and lift the pipe under the action of the clamping mechanism, and at the same time, a circle limiting structure can be formed between the clamp and the gripping clamp under the action of the locking mechanism, thereby effectively ensuring that the pipe is not easy to fall off after being clamped and lifted, and enhancing the practicality and stability of the device.

[0034] The clamping mechanism includes a movable groove 6, a gripping clamp 10 and a gripping drive unit. The movable groove 6 is provided at the other end of the housing 1. The gripping clamp 10 completes the pipe gripping work through the gripping drive unit disposed in the movable groove 6.

[0035] The locking mechanism is arranged on the grabbing clamp 10 .

[0036] The clamping drive unit includes a rotating gear 7, a driven gear 8, a driven rotating rod 9, a grabbing clamp 10 and a hinged rod 11. The rotating gear 7 is fixed on the active rotating rod 2 and is located in a movable groove 6. The rotating gear 7 is meshed with one of the driven gears 8. Both ends of the two driven rotating rods 9 are arranged in the movable groove 6 through bearings. The two driven gears 8 are fixed on the driven rotating rod 9 and the two driven gears 8 are meshed with each other. The driven rotating rod 9 and the grabbing clamp 10 are hingedly connected. One end of the two hinged rods 11 is hinged in the movable groove 6, and the other end of the hinged rod 11 is hinged on the grabbing clamp 10.

[0037] A rubber pad 12 is provided on one side adjacent to the two gripping clips 10 , and the rubber pad 12 is provided with anti-slip grooves.

[0038] The implementation principle of a stable and reliable natural gas pipeline hanger in the embodiment of the present application is as follows: first, after passing the rope through multiple hooks 4, the two ends of the rope are fixed on the crane, and then the gripper 10 is moved above the hanging pipe. Start the motor 3, drive the active rotating rod 2 to rotate, so that the multiple rotating gears 7 rotate clockwise. Then drive the driven gear 8 to rotate counterclockwise, and the hinged rods 11 move away from each other. Drive the ends of the two grippers 10 away from the driven gear 8 away from each other, and then gradually move the outer shell 1 down to the pipeline so that the pipeline is located between the two grippers 10, and then make the motor 3 rotate in the opposite direction, drive the two grippers 10 to approach each other to clamp the pipeline, so that the rubber pad 12 is squeezed and fit on the pipeline, and then the rotation of the motor 3 can be stopped. At this time, the two grippers 10 complete the clamping work of the pipeline.

[0039] When the buckle 21 is pulled, the rope 20 passes through the extension groove 15, driving the slide plate 17 to rotate in the slide plate groove 18, causing the spring outside the round rod 16 to deform, and the buckle 21 passes through the slot 24 to make it contact with the pull rod 27, and continuously presses the pull rod 27 to the outside of the movable slot 25, so that the tension spring 26 is stretched. When the pull rod 27 and the slot 24 coincide, the pull rod 27 is driven to be inserted into the slot 24 under the elastic action of the tension spring 26, and the position of the slot 24 can be fixed. At this time, the rope 20 is attached to the pipe wall, and a card hole is provided on the rope 20, and a round hook for limiting the card hole is provided on one side of the extension groove 15. After the slot 24 is limited, the card hole on the rope 20 is just stuck on the round hook, so that the rope 20 can fit tightly with the pipe. If the pipe falls, the card hole will contact the round hook, making the pipe unable to fall.

[0040] After the pipeline is transported to the designated position, the pull rod 27 is first gradually moved out of the movable groove 25, the tension spring 26 is stretched, and then the pull rod 27 cannot be stuck in the slot 24, and the rope 20 is driven to pass through the extension groove 15 again and be wrapped around the round rod 16 under the rebound action of the spring outside the round rod 16. During the process, the card hole on the rope 20 is also separated from the round hook on one side of the extension groove 15. When the rope 20 is completely retracted into the contraction groove 14, only the buckle 21 remains outside the contraction groove 14. At this time, the motor 3 is started to drive the two grippers 10 to separate from each other to complete the unloading of the pipeline.
