Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic chucks, and more specifically, particularly relates to a hydraulic chuck used in oil fields. Background Art

[0002] At present, oil fields mostly use portable slips to lower or remove pipes into wells. When using, the slips must be opened first, the pipes must be clamped, and then the slips must be locked. After the pipes are sent to the required position, the slips must be opened manually to remove the pipes. Since the slips themselves are relatively heavy, generally 60-80 kilograms, they need to be equipped with multiple people in shifts, the labor intensity of the workers is high, and the safety factor is low.

[0003] The hydraulic chuck of the prior art is relatively simple in configuration, and the clamping block of the sliding clamping structure on the chuck is relatively small, which causes the workpiece to slip easily when clamped, and excessive clamping can easily damage the outer surface of the workpiece, making it unsafe and reliable to use.

[0004] In summary, the utility model provides a hydraulic chuck for oil fields to solve the above problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a hydraulic chuck for oil fields, which is achieved by the following specific technical means:

[0007] Furthermore, a movable groove 1 is opened on one side of the card seat, a movable groove 2 is opened on one side of the movable groove 1, a fixing piece 2 is installed on one side of the connecting frame, a limiting block 2 is installed inside the movable groove 2, a limiting block 1 is installed on one side of the limiting block 2, the limiting block 1 penetrates the movable groove 1, and the limiting block 1 is rotatably installed on one side of the fixing piece 2.

[0008] Furthermore, there are two card seats, and anti-slip threads are provided on opposite sides of the two card seats.

[0009] Furthermore, there are two connecting frames, which correspond one to one with the two card seats.

[0010] Furthermore, the fixing bolt is not in contact with the connecting plate, and the diameter of the portion of the fixing bolt that passes through the fixing hole is smaller than the diameter of the fixing hole.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model controls the hydraulic rod to make the hydraulic rod drive the two connecting plates two to move away from each other, so that the two connecting plates two drive one end of the connecting frame close to the connecting plate two to move away from each other, so that the one end of the connecting frame close to the connecting plate one is close to each other, and then the two connecting plates one are connected by a fixing bolt, and the fixing bolt can be easily moved during the connection, and then the hydraulic rod is controlled to make the hydraulic rod contract to drive the two connecting plates two to move closer. Since the two connecting plates one are connected by the fixing bolt, one end of the connecting frame is fixed, and the two connecting plates two are close to each other, driving the other end of the connecting frame to move closer, so that the circle surrounded by the connecting frame as a whole is contracted, and then the circle surrounded by the clamping seat is contracted, so that the clamping seat can fix the workpiece, and at the same time the hydraulic rod can adjust the clamping force to avoid damaging the outer surface of the workpiece.

[0022] like Figures 1 to 3 As shown, the utility model provides a hydraulic chuck for oil fields, comprising a base 1, a chuck 2 is slidably mounted on the upper side of the base 1, a connecting frame 4 is arranged on the side of the chuck 2, a connecting plate 7 is arranged at one end of the connecting frame 4, a fixing hole 8 is opened inside the connecting plate 7, a fixing bolt 9 is arranged inside the fixing hole 8, a connecting plate 2 5 is mounted at one end of the connecting frame 4, a fixing piece 14 is arranged on one side of the connecting plate 2 5, a hydraulic rod 6 is rotatably mounted on one side of the fixing piece 14, and another side of the fixing piece 14 is rotatably mounted on the other end of the hydraulic rod 6, and the other fixing piece 14 is mounted on one side of another connecting frame 4, and the hydraulic rod 6 is controlled so that the hydraulic rod 6 can be brought into contact with the hydraulic rod 6. The two connecting plates 25 are moved away from each other, so that the two connecting plates 25 drive one end of the connecting frame 4 close to the connecting plate 25 to move away, so that the end of the connecting frame 4 close to the connecting plate 17 is close to each other, and then the two connecting plates 17 are close to each other, and then the two connecting plates 17 are connected by the fixing bolt 9, and the fixing bolt 9 can be easily moved during the connection, and then the hydraulic rod 6 is controlled to make the hydraulic rod 6 contract, so as to drive the two connecting plates 25 to move closer. Since the two connecting plates 17 are connected by the fixing bolt 9, one end of the connecting frame 4 is fixed, and the two connecting plates 25 are close to each other, driving the other end of the connecting frame 4 to move closer, so that the circle surrounded by the connecting frame 4 as a whole is contracted, and then the circle surrounded by the clamping seat 2 is contracted, so that the clamping seat 2 can fix the workpiece.

[0023] Among them, a movable groove 12 is opened on one side of the movable groove 12, a movable groove 2 13 is opened on one side of the movable groove 12, a fixing part 2 15 is installed on one side of the connecting frame 4, a limiting block 2 11 is installed inside the movable groove 2 13, a limiting block 10 is installed on one side of the limiting block 2 11, the limiting block 10 passes through the movable groove 12, and the limiting block 10 is rotatably installed on one side of the fixing part 2 15, and the limiting block 10 slides in the movable groove 12 and the limiting block 2 11 slides in the movable groove 2 13, so that the connecting frame 4 can conveniently drive the card holder 2 to move.

[0028] The utility model discloses a hydraulic chuck for oil fields. In actual use, the workpiece is first placed between the two clamping seats 2, and then the hydraulic rod 6 is operated to make the hydraulic rod 6 drive the two connecting plates 25 to move away from each other, so that the two connecting plates 25 drive one end of the connecting frame 4 close to the connecting plate 25 to move away from each other, so that the one end of the connecting frame 4 close to the connecting plate 1 7 is close to each other, and then the two connecting plates 1 7 are close to each other, and then the two connecting plates 1 7 are connected by the fixing bolt 9, and the fixing bolt 9 can be conveniently moved during connection, and then the hydraulic rod 6 is operated to make the hydraulic rod 6 shrink, so as to drive the two connecting plates 25 to move closer. Since the two connecting plates 1 7 are connected by the fixing bolt 9, one end of the connecting frame 4 is fixed, and the two connecting plates 25 are close to each other, driving the other end of the connecting frame 4 to move closer, so that the circle surrounded by the connecting frame 4 as a whole shrinks, and then the circle surrounded by the clamping seat 2 shrinks, so that the clamping seat 2 can fix the workpiece, and at the same time, the hydraulic rod 6 can adjust the clamping force to avoid damaging the outer surface of the workpiece.
