Abstract
The utility model relates to a wrench head braking and steering control mechanism for power wrenches, which is used for loading and unloading threads of pipe columns in the oil field drilling and extraction engineering. The wrench head braking and steering control mechanism integrates a braking mechanism and a steering control mechanism of the prior art together, and is arranged on the top part of a wrench head of the power wrench; a brake disc and a friction plate of the braking mechanism are fixed to a cover plate of the wrench head; the steering control mechanism is fixed to brake plates; the brake plate and a jaw frame are in a slide key joint. Thereby, the technical performance of the existing power wrench is improved, and the use, the maintenance, the lubrication and the adjustment of the power wrench are more convenient.
Description
The utility model be used in the oil field drilling engineering unloading the tubing string screw thread Power Tong a kind of binding clip braking and turn to controlling organization, be applicable to various Power Tongs.
It is two independent agencies that existing Power Tong binding clip arrestment mechanism and binding clip turn to controlling organization, respectively accounts for requisite space, does not melt mutually mutually, and the former is made up of parts such as friction plate, brake(-holder) block, brake disc, spring, bolts.Friction plate and brake disc are fixed on the foot position of Power Tong binding clip housing, jaw plate frame stretches out the neck shin and connects with brake(-holder) block formation slide key from the bottom, the latter is made up of the knob that resets, rotation axis, backing pin, reset knob and rotation axis is arranged on the opening gear cap of binding clip topmost position, and backing pin is arranged on the jaw plate frame.Arrestment mechanism is arranged on binding clip foot position, and the following problem of band rice: resettlement is shelved and easily collided with easily to advance earth, and installation, adjustment, lubricated, fastening all very inconvenient are especially under the suspention duty, all the more so.All be difficult for finding to screw loosening is come off, adjust very difficulty of braking moment.When Power Tong and hydraulic back pincers are used in combination, it is this that to divide into structure more inapplicable, adjust fastening very inconvenience, in addition, it is also bigger to strength reduction that rotation axis is set on the opening gear cap, and with regard to prior art, can't move original arrestment mechanism to the binding clip topmost from the binding clip foot simply, because does not melt with the arrestment mechanism requisite space mutually for turning to controlling organization shared in binding clip opening gear cap topmost space.The purpose of this utility model will overcome the deficiencies in the prior art part exactly, brake and turn to controlling organization by a kind of novel Power Tong binding clip that structure modify provides both to combine together, be arranged on Power Tong binding clip topmost, improve its prior art performance, make things convenient for condition for installation, maintenance, adjustment, lubricated, fastening creation.
For achieving the above object, the technical scheme that the utility model adopted is: opening gear cap top is provided with backing pin, turn to controlling organization to be arranged on the brake(-holder) block, jaw plate frame protrudes upward the neck shin and connects with brake(-holder) block formation slide key, friction plate that contacts with brake(-holder) block and brake disc are fixed on the binding clip cover plate on binding clip top, thereby make the binding clip arrestment mechanism of Power Tong and turn to controlling organization to combine together, and be in the optimum position, top, make the installation of incorporate two mechanisms, maintenance, adjust, lubricated, fastening very convenient, the weakening of splitting ability to speak wheel intensity also makes moderate progress.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is a Power Tong binding clip partial view.
Fig. 2 is the A-A view of Fig. 1.
Fig. 3 is another kind of stiffening plate installation drawing.
With reference to accompanying drawing 1,2, (13) are that opening gear cap, (12) are that jaw plate frame, (11) are that down friction plate, (8) for upper friction plate, (10) for brake disc, (1) for braking bolt, (2) be tripping spring, (4) for reset knob, (3) for rotation axis, (6) be stiffening plate for backing pin, (7) for brake(-holder) block, (9) for binding clip cover plate, (5).Following friction plate (9) is fixed on the binding clip cover plate (11), and upper friction plate (8) is fixed on the brake disc (10), and brake disc is fixed on the binding clip cover plate (11) by braking bolt (1).Brake(-holder) block (7) and stiffening plate (6) are anchored on one, and jaw plate frame (12) protrudes upward between neck shin and the stiffening plate (6) and connects for slide key.The knob (4) that resets is fixed on the rotation axis (3), and rotation axis (3) is contained on the brake(-holder) block (7) with stiffening plate (6), and backing pin (5) is fixed on the opening gear cap (13).The track groove (14) that has restriction backing pin slewing area on the stiffening plate (6).The direction of turning knob axle breach (15) can retrain the backing pin slewing area, realizes turning to control.
With reference to accompanying drawing 3, in the time of on stiffening plate (6) places brake(-holder) block (7), have on the brake(-holder) block (7) as the spacing track groove of the backing pin on the stiffening plate.
During work, the knob (4) that will reset is twisted to rotation direction, brake disc (10) produces flexible thrust by braking bolt (1) and tripping spring (2) to brake(-holder) block (7), jaw plate frame (12) is braked with respect to binding clip cover plate (11) by brake(-holder) block (7), when opening gear cap (13) when turning over certain angle, jaw on the jaw plate frame is pushed to center of rotation and clamps tubing string, then, jaw plate frame, brake(-holder) block, the knob that resets, rotation axis, opening gear together rotate together with tubing string, unload the screw thread operation in the enforcement.Last shackle finishes, and jaw plate frame still is braked, the counter-rotating of opening gear, jaw plate frame is removed and is clamped, backing pin on the opening gear cap (5) is kept off by the breach of rotation axis (3) bottom, and stall after jaw plate frame aligns with the breach of opening gear is finished and once gone up button or shackle operation.
Claims (2)
1. one kind by upper friction plate (8), following friction plate (9), brake(-holder) block (7), brake disc (10), bolt (1), spring (2), stiffening plate (6), knob (4) resets, controlling organization is braked and turned to the Power Tong binding clip that rotation axis (3) and backing pin (5) are formed, it is characterized in that: following friction plate (9) and brake disc (10) are fixed on the binding clip cover plate (11), rotation axis (3) is fixed on the brake(-holder) block (7) with stiffening plate, backing pin (5) is fixed on the opening gear cap (13), and jaw plate frame (12) protrudes upward the neck shin and connects with stiffening plate or brake(-holder) block formation slide key.
2. by the described a kind of Power Tong binding clip braking of claim 1 and turn to controlling organization, it is characterized in that: have on the stiffening plate (6) on spacing track groove of backing pin (14) or the brake(-holder) block (7) and have as the spacing track groove of the backing pin on the stiffening plate (6).
