Description

[0002] The manifold is a combination of multiple pipelines. It includes gate valves, pipelines, pipe fittings, pressure gauges, electronic sensors, hydraulic control systems and other accessories. The manifold can carry out oil and gas production under high pressure.

[0003] When the manifold is used for oil and gas production, multiple sections of pipelines will be spliced ​​together so that they can be transported after being spliced. However, the application of the pipelines is relatively special and their specifications are relatively large, which makes it inconvenient to connect the pipelines, thereby affecting the efficiency of pipeline transportation. When the pipelines are connected, only flanges are used for connection. The high-pressure transportation of the manifold causes the flanges to be under too much pressure, making the two pipelines very likely to break during transportation, thereby affecting the efficiency of oil and gas production.

[0028] A motor 4 is fixedly mounted on the processing table 1, and a rotating shaft 5 which is transmission-connected to two driven racks 8 is fixedly connected to the output end of the motor 4. The rotating shaft 5 is vertically arranged, and a driving gear 6 which is meshingly connected to the two driven racks 8 is fixedly mounted on the rotating shaft 5;

[0029] The guide rod 7 is horizontally arranged at both sides of the rotating shaft 5, a connecting plate 9 is fixedly installed on the driven rack 8, and a connecting column 10 is fixedly installed on the connecting plate 9, a guide plate 11 and a fixing seat 12 are fixedly installed on the connecting column 10, and the feed pipe 2 is arranged in the fixing seat 12, the output end of the motor 4 drives the rotating shaft 5 to rotate clockwise, the rotating shaft 5 drives the driving gear 6 to rotate and pulls the two driven racks 8 in meshing connection, so that the driven rack 8 drives the fixing seats 12 to move toward each other when moving, and the two fixing seats 12 can realize bidirectional movement, so that the feed pipe 2 and the conveying pipe 3 are more convenient to dock, thereby reducing the work intensity of the operator;

[0030] The processing table 1 is connected to a moving seat 17 via a lifting member, and the conveying pipe 3 is arranged on the moving seat 17;

[0031] The lifting member includes a motor 2 14 fixedly mounted on the processing table 1, and a bidirectional screw 15 is fixedly connected to the output end of the motor 2 14, and two matching nuts 16 are provided on the sliding sleeve of the bidirectional screw 15. A limit rod 19 is fixedly mounted on the processing table 1, and a moving seat 17 is arranged on the limit rod 19. The limit rod 19 guides the moving seat 17, thereby limiting the moving direction of the nut 16.

[0032] A traction rod 18 is connected between the moving seat 17 and the two nuts 16, the bidirectional screw rod 15 is horizontally arranged, the limit rod 19 is vertically arranged, and the moving seat 17 is slidably sleeved on the limit rod 19, and the two ends of the traction rod 18 are respectively connected to the moving seat 17 and the nut 16 pin shaft;

When the nut 16 moves, the traction rod 18 is deflected, and when the traction rod 18 is deflected, the moving seat 17 is driven to slide on the limit rod 19, so that the moving seat 17 can adjust the height of the conveying pipe 3, so that the feeding pipe 2 and the conveying pipe 3 can be docked more quickly;

[0034] A clamping plate 20 is fixedly mounted on the feed pipe 2, and a limiting component for limiting the clamping plate 20 is installed on the movable seat 17;

After the hydraulic cylinder 21 is energized, it can drive the connecting end 22 to perform lifting operations. When the output end of the hydraulic cylinder 21 contracts, it can drive the pressure plate 27 to move down to the feed pipe 2 and correspond to the clamping plate 20;

[0036] A pressure plate 27 for clamping the clamping plate 20 is fixedly installed on the second nut 26, the bracket 23 and the second bidirectional screw rod 25 are horizontally arranged from top to bottom, the pressure plate 27 is vertically arranged at both sides of the bracket 23, and a limit plate 28 is fixedly installed on the second nut 26, and a limit hole for guiding the limit plate 28 is provided on the bracket 23;

[0037] When the feed pipe 2 is docked with the conveying pipe 3, the output end of the motor 3 24 drives the two-way screw rod 25 to rotate, and the two-way screw rod 25 drives the two nuts 26 to move toward or in the opposite direction when rotating. When the two nuts 26 move toward each other, they drive the pressure plate 27 to squeeze the clamping plate 20 from both sides, so that the feed pipe 2 and the conveying pipe 3 can always be connected. The limiting hole guides the limiting plate 28, thereby limiting the moving direction of the nut 26;

[0038] When the feeding pipe 2 and the conveying pipe 3 need to perform conveying operations, the motor 2 14 is driven to adjust the height of the moving seat 17, so that the moving seat 17 can quickly adjust the height of the conveying pipe 3 when moving;

[0039] The output end of the motor 1 4 can drive the rotating shaft 5 to rotate, so that when the two fixing seats 12 move toward each other, the feed pipe 2 and the conveying pipe 3 are driven to dock, and the two corresponding flanges are connected by the locking bolt;

[0040] The output end of the hydraulic cylinder 21 can be extended to adjust the height of the pressure plate 27, and the output end of the motor 3 24 drives the two-way screw 25 to rotate, so that the two nuts 26 move toward each other and drive the pressure plate 27 to press the clamping plate 20, so that the feed pipe 2 and the conveying pipe 3 can be used for oil and gas extraction operations;

[0041] It should be noted that the specific models and specifications of motor 1 4 , motor 2 14 , motor 3 24 , and hydraulic cylinder 21 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it is not repeated here.

[0042] The present invention can be explained by the following operation mode:

[0043] Install the two feed pipes 2 in the fixed seat 12, and install the delivery pipe 3 in the movable seat 17;

[0044] When it is necessary to operate through the feed pipe 2 and the conveying pipe 3;

[0045] The output end of the motor 2 14 drives the bidirectional screw 15 to rotate, and the bidirectional screw 15 drives the two nuts 16 to move toward or in opposite directions when rotating;

[0046] When the nut 16 moves, the traction rod 18 is deflected, and the position difference generated by the traction rod 18 during the deflection can pull the moving seat 17, so that the height of the moving seat 17 can be adjusted when the moving seat 17 slides on the limit rod 19, and the conveying pipe 3 on the moving seat 17 corresponds to the two feeding pipes 2;

[0047] The output end of the motor 4 drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the driving gear 6 to pull the two driven racks 8. When the driven racks 8 slide on the guide rods 7, they pull the connecting plate 9. The connecting plate 9 drives the guide plate 11 and the fixed seat 12 to move. When the guide plate 11 moves, it can extend into the guide slot 13, so that the two fixed seats 12 move toward each other and drive the two feeding pipes 2 to gradually approach the conveying pipe 3;

[0048] After the feed pipe 2 and the delivery pipe 3 are butted, the two corresponding flanges are butted and connected using locking bolts;

[0049] The output end of the hydraulic cylinder 21 moves downward, driving the connecting end 22 to move downward, and the connecting end 22 drives the bracket 23 to move downward synchronously, so that the two pressure plates 27 can be located at both sides of the clamping plate 20;

[0050] The output end of the motor 3 24 drives the bidirectional screw rod 2 25 to rotate, and the bidirectional screw rod 25 drives the two nuts 26 to move toward or in opposite directions when rotating;

[0051] When the two nuts 26 move toward each other, the limiting plate 28 and the pressure plate 27 are driven to move synchronously. When the limiting plate 28 moves, it can slide in the limiting hole in the bracket 23. The pressure plate 27 moves toward each other from both sides and clamps the clamping plate 20, so that the feed pipe 2 and the conveying pipe 3 are fully connected;

[0052] The conveying operation can be performed through the feed pipe 2 and the conveying pipe 3.
