Abstract
The utility model relates to a heating straightener for a sucker rod. The heating straightener for a sucker rod is provided with an elongated bed body which is made from steel. Both ends of the bed body are respectively provided with an oil hydraulic cylinder. The movable parts of the oil hydraulic cylinders are provided with clamps which can clamp the head of the sucker rod. Rails which are parallel to the longitudinal direction of the bed body are arranged beside the bed body. A trolley which can move along rails is arranged on the rails, and the trolley is provided with an intermediate frequency induction heating coil. The intermediate axis line of the coil is arranged on the connecting line of the clamps which are arranged on the two oil hydraulic cylinders. When the heating straightener for a sucker rod is used, the bended sucker rod is made to penetrate through the coil, and the bended sucker rod is clamped between the clamps of the oil hydraulic cylinders which are arranged at both ends of the bed body, and the sucker rod is caused to stay in the drawing state. At the same time, the bended sucker rod is heated by the intermediate frequency induction coil, the sucker rod is gradually straightened in the semi-permeable heat state.
Description
The utility model relates to a kind of straightener, the heater and the straightening device of the hot straightener of particularly a kind of sucker rod.
Because of operations such as wells, can cause some rod sags distortion when sucker rod uses in the oil field,, can reuse by alignment to the sucker rod of bending.In prior art, sucker rod to bending does not also have special-purpose alignment equipment, generally all be to adopt artificial or mechanical straighten while cold method, because bent rod produces bending stress in deformed part branch, adopt the method for straighten while cold not only can not eliminate these bending stresses, but also can produce new stress because of flow harden, the existence of these stress greatly influences the service life of the sucker rod after the alignment.
The purpose of this utility model is in order to overcome above-mentioned shortcoming, a kind of hot straightener of sucker rod that adopts Frequency Induction Heating to be provided.
The utility model is realized with the following method.
Crooked sucker rod with the tension of oil pressure straightening device, is added the sucker rod of thermal flexure with intermediate frequency induction heating device, make it under the state of semi-transparent heat, stretching with the oil pressure straightening device crooked sucker rod.
For realizing such scheme, make long and narrow lathe bed with metal, at the lathe bed two ends oil hydraulic cylinder is arranged, the movable part of oil hydraulic cylinder, but the anchor clamps that the clamping sucker rod head is arranged, anchor clamps line and lathe bed parallel longitudinal, crooked sucker rod can be clamped between two anchor clamps on the oil pressure straightening device, guide rail with the lathe bed parallel longitudinal is arranged by lathe bed, having on the guide rail can be along the chassis of guide rail activity, be fixed with the Frequency Induction Heating coil on the chassis, the axis of coil is on the line of two anchor clamps, and the coil two ends are connected on the intermediate frequency power supply.During use, allow crooked sucker rod from induction coil, pass, crooked rod grip is held between two anchor clamps on the oil pressure straightening device, start oil pressure pump, the sucker rod that tension is crooked, use the sucker rod of Frequency Induction Heating coil heats bending simultaneously, make sucker rod under the state of semi-transparent heat, stretching the sucker rod of bending gradually with the oil pressure straightening device.
Because the utility model makes crooked sucker rod under the state of semi-transparent heat, stretching gradually with the oil pressure straightening device, so crooked sucker rod is after alignment, can eliminate the stress of sweep, and can not produce new stress, make the performance of the sucker rod after the alignment, can reach the performance of new bar.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the schematic top plan view of the hot straightener of sucker rod.
Among Fig. 1, the lathe bed 1 of the hot straightener of sucker rod is to make with steel, be narrow and long rectangular, at the two ends of lathe bed 1 oil hydraulic cylinder 2 is arranged respectively, the piston rod 22 of oil hydraulic cylinder 2 is fixed on lathe bed 1 two ends, but be fixed with the anchor clamps 21 of clamping sucker rod 10 on mobilizable oil cylinder, two anchor clamps 21 are relative, the parallel longitudinal of its line and lathe bed 1, other at lathe bed 1, the guide rail 4 parallel with lathe bed 1 arranged, chassis 5 is arranged on the guide rail 4, chassis 5 usefulness motors 7 drive and can move on guide rail 4 by chain 8, Frequency Induction Heating coil 6 are installed, when chassis 5 moves on guide rail 4 on the chassis 5, the axis of coil 6 is all the time on the line of two anchor clamps 21, the two ends of Frequency Induction Heating coil 6 are connected on the intermediate frequency power supply 9, and the oil pipeline of the oil hydraulic cylinder at lathe bed two ends is connected on the oil pressure station 3.
The oil hydraulic cylinder at lathe bed two ends also can be that oil cylinder is fixed on the lathe bed, on mobilizable piston rod anchor clamps is arranged.
Claims (4)
1, the hot straightener of a kind of sucker rod is characterized in that:
(1) it has the long and narrow lathe bed of steel, and there is oil hydraulic cylinder at the lathe bed two ends, but the movable part of oil hydraulic cylinder has the anchor clamps of clamping sucker rod head,
(2) the other guide rail that has with the lathe bed parallel longitudinal of lathe bed has on the guide rail and can be fixed with the Frequency Induction Heating coil on the chassis along the chassis of guide rail activity.
2, by the described hot straightener of claim 1, it is characterized in that: described oil pressure stretching device is two oil hydraulic cylinders that piston rod is separately fixed at the lathe bed two ends.
3, by the described hot straightener of claim 1, it is characterized in that: described oil pressure stretching device is two oil hydraulic cylinders that oil cylinder is separately fixed at the lathe bed two ends.
4, by claim 2 or 3 described hot straighteners, it is characterized in that: the axis of described Frequency Induction Heating coil, on the line of described two anchor clamps.
