Description

Technical Field

[0001] This utility model relates to the field of pipe and rod conveyor technology, and in particular to a gripping feeding mechanism. Background Technology

[0002] The tube column conveyor feeds the tube column on the tube rack into the conveyor through the feeding mechanism. There are two types of feeding mechanism: hook feeding and grab feeding. Both feeding methods are hydraulically driven mechanical feeding.

[0003] In hook-type feeding, the L-shaped feeding arm driven by a hydraulic cylinder hooks the pipe column from the pipe rack. Then, the pipe column rolls into the conveyor under gravity along the feeding arm. This method produces a lot of impact and noise when the pipe column rolls down. In gripping feeding, the feeding arm with claws driven by hydraulics grips the pipe column from the pipe rack and places it onto the conveyor. This method is limited by the rotation radius of the feeding arm, which is not adaptable to pipe racks of different heights. In addition, the existing feeding mechanism is installed on the conveyor by bolts. When the feeding mechanism needs to be replaced or disassembled, it takes a long time and is inconvenient. Therefore, a gripping feeding mechanism is proposed. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing feeding mechanism of the pipe rod conveyor, which is limited by the rotation radius of the feeding arm and has insufficient adaptability to pipe racks of different heights. In addition, the existing feeding mechanism is installed on the conveyor by bolts, which takes a long time and is inconvenient when the feeding mechanism needs to be replaced or disassembled. Therefore, a gripping feeding mechanism is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A gripping feeding mechanism includes a gantry, characterized in that a lifting frame slides vertically within the gantry, the lifting frame is connected to a feeding arm via a through shaft, and the through shaft is actuated by a gear and rack assembly;

[0007] The gear and rack assembly includes:

[0008] Gear, located at the end of the through shaft;

[0009] A rack is disposed on the outer wall of the gantry and meshes with the gear.

[0010] Preferably, the gantry is fixedly connected to a first connecting plate, and a clamping plate that can move relative to or away from each other is provided on one side of the first connecting plate. The clamping plate is used for positioning and installing the first connecting plate.

[0011] Preferably, the clamping plate is driven by a threaded rod, which is driven by a drive motor disposed on the first connecting plate.

[0012] Preferably, the lifting frame is driven by a lifting hydraulic cylinder mounted on the gantry.

[0013] Preferably, the gantry is provided with a through-spindle bracket for through-spindle installation.

[0014] Preferably, the through shaft frame includes a second connecting plate and a second connecting plate fixedly installed on the lifting frame, and the through shaft rotatably passes through the second connecting plate and the second connecting plate.

[0015] Preferably, the gear includes a driving gear and a driven gear, which are respectively disposed at both ends of the through shaft.

[0016] Preferably, an electromagnetic clutch is also provided on the through shaft.

[0017] Preferably, the feeding arm is provided with clamping claws.

[0018] Preferably, the gripping claw includes a first gripper and a second gripper that can move relative to or away from each other.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. When in use, this equipment can grip the tube column by combining the first and second grippers through the gripping mechanism. Then, through the lifting mechanism, the through shaft and the electromagnetic clutch drive the drive gear and driven gear to rise along the rack. The through shaft drives the feeding arm to rise, and the feeding arm drives the tube column to rise. This solves the noise and impact problems when feeding tube columns in the tube conveyor and can meet the feeding needs of tube racks of different heights.

[0021] 2. When using this equipment, the clamps and limit blocks on both sides can move closer to each other as the threaded rod rotates, thus fixing the feeding mechanism to the pipe rod conveyor. When the feeding mechanism needs to be replaced or disassembled, the time required is short and it is more convenient. Attached Figure Description

[0026] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-3 The gripping feeding mechanism includes a gantry 1. A rack 2 is fixedly connected to one side of the gantry 1. A drive gear 3 and a driven gear 4 are provided on one side of the gantry 1. The drive gear 3 and the driven gear 4 mesh with the rack 2 on both sides of the gantry 1 respectively. A lifting mechanism and a lifting frame 5 are provided between the gantry 1. Through the cooperation between the rack 2, the drive gear 3 and the driven gear 4, the lifting mechanism can drive the lifting frame 5 to move up and down between the gantry 1.

[0028] A loading arm 7 is provided on one side of the gantry 1. The loading arm 7 is equipped with clamping claws, including a first clamping claw 8 and a second clamping claw 9. The loading arm 7 is equipped with a gripping mechanism, which controls the first clamping claw 8 and the second clamping claw 9 on the loading arm 7 to grip and fix the tube column.

[0029] The lifting mechanism includes a lifting cylinder 12 mounted on the gantry 1. One end of the lifting cylinder 12 is fixedly connected to a connecting block 13. The connecting block 13 is fixedly connected to one side of the lifting frame 5. When the lifting cylinder 12 extends or retracts, the driving gear 3 and the driven gear 4 can rotate along the rack 2.

[0030] A second connecting plate 14 is fixedly connected to one side of the lifting frame 5, and a third connecting plate 15 is fixedly connected to the other side of the lifting frame 5. A through shaft is provided between the second connecting plate 14 and the third connecting plate 15. The driving gear 3 and the driven gear 4 are fitted at both ends of the through shaft. The driving gear 3 is connected to the electromagnetic clutch 6 fixed on the through shaft. The driven gear 4 guides and supports the through shaft. One end of the loading arm 7 is fixedly connected to the through shaft. When the driving gear 3 and the driven gear 4 move up and down along the rack 2, they can drive the loading arm 7 on the through shaft to move up and down. When the loading arm 7 is raised to the set height, the electromagnetic clutch 6 is energized to drive the loading arm 7 to rotate and clamp the tube column into the conveyor, so as to meet the needs of loading tube racks of different heights.

[0031] The gantry 1 has sliding grooves on both sides. The lifting frame 5 and the connecting block 13 are each fixedly connected to one side of the sliding block 16. The sliding block 16 is slidably connected to the sliding groove. The sliding block 16 moves up and down with the lifting frame 5 and the connecting block 13. When loading materials, the cooperation between the sliding block 16 and the sliding groove limits the lifting frame 5 and the connecting block 13, so that they can only move vertically.

[0032] The gripping mechanism includes a connecting rod 17, with a gripper cylinder 18 mounted on one side of the connecting rod 17. This cylinder controls the first gripper 8 and the second gripper 9 to clamp the tubing. The first gripper 8 has a rectangular groove. Both ends of the connecting rod 17 are rotatably connected to the feeding arm 7. One end of the gripper cylinder 18 is rotatably sleeved with a connecting post 26. Both ends of the connecting post 26 are fixedly connected to sliding posts, which are slidably connected to the rectangular groove. When the gripper cylinder 18 extends or retracts, the connecting post 26 drives the sliding posts to slide within the rectangular groove, changing the angle of the first gripper 8 and thus controlling the opening and closing of the first gripper 8.

[0033] A first rotating rod and a second rotating rod are rotatably connected between the feeding arms 7. A first gear 19 is fixedly connected to the first rotating rod, and a second gear 20 is fixedly connected to the second rotating rod. The second gear 20 meshes with the first gear 19. A first gripper 8 and a second gripper 9 are fixedly connected to the first gear 19 and the second gear 20, respectively. The first gripper 8 and the second gripper 9 rotate around the first gear 19 and the second gear 20, respectively. When the first gripper 8 opens and closes, the meshing of the first gear 19 and the second gear 20 drives the second gripper 9 to open and close together with the first gripper 8.

[0034] The gantry 1 is fixedly connected to a first connecting plate 10. A clamping plate 11 is provided on one side of the first connecting plate 10. A fixing mechanism is provided on one side of the first connecting plate 10. Through the fixing mechanism, the three sets of clamping plates 11 are controlled to fix the device to one side of the tube conveyor, which facilitates the replacement and disassembly of the feeding mechanism.

[0035] The fixing mechanism includes a rotating rod rotatably connected to the first connecting plate 10. One end of the rotating rod is fixedly connected to a first bevel gear 22. The first connecting plate 10 is rotatably connected to a threaded rod 23. One end of the threaded rod 23 is fixedly connected to a second bevel gear 24. The second bevel gear 24 meshes with the first bevel gear 22. Through the meshing of the first bevel gear 22 and the second bevel gear 24, when the rotating rod rotates, it can drive the threaded rod 23 on the first connecting plate 10 to rotate.

[0036] The fixing mechanism also includes a drive motor 21 mounted on the top of the first connecting plate 10, and a rotating rod fixed to the output end of the drive motor 21.

[0037] A movable nut is provided on the threaded rod 23. The movable nut is fixedly connected to the clamping plate 11. A limit block 25 is fixedly connected to one side of the clamping plate 11. By moving the nut, the clamping plates 11 on both sides can move closer to each other as the threaded rod 23 rotates, thus fixing the feeding mechanism to the pipe rod conveyor.

[0038] The specific models and specifications of the drive motor 21, electromagnetic clutch 6, lifting cylinder 12, and gripper cylinder 18 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation methods adopt existing technologies in this field, so they will not be elaborated here.

[0039] The working principle of this utility model:

[0040] When the lifting cylinder 12 extends, it drives the lifting frame 5 to rise, which in turn drives the loading arm 7 to rise vertically. When it reaches the set height, the electromagnetic clutch 6 is energized, driving the loading arm 7 to rotate and clamp the tubing string into the conveyor. This meets the needs of loading tubing racks at different heights. Furthermore, the gripping action of the first gripper 8 and the second gripper 9 eliminates impact and noise during the tubing string loading process. In addition, the modular design of the gripping loading mechanism allows it to be rotated and installed on either side of the conveyor depending on the well site conditions.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
