Abstract
A concave pit returning device is characterized in that a circular arc top head is arranged on a circular arc jacking and hydraulic cylinder 2; a positioning ruler 4 is arranged on a positioning rod 6; a fixed frame 5 is connected with the positioning rod 6; the positioning rod 6 is fixed on a traction rod 11 by a fixed bolt 7; and a hydraulic oil pipe 8 is communicated with a manual hydraulic station 9 and the circular arc jacking and hydraulic cylinder 2 and is fixedly connected with the circular arc jacking and hydraulic cylinder 2. The concave pit returning device has the beneficial effects that the concave pit returning device has uniform stress, is accurate to position and is suitable for various specifications of pipe bodies; an artificial hydraulic power source has uniform power transfer, short travel, quick speed and low energy consumption, is free from pollution, operates at a normal temperature of above 0 DEG C and completely conforms to the national low carbon environmental protection requirements; small concave pits on the pipe bodies can get back to the original shapes; after ultra-large concave pits get back, the drift diameter is smooth, so that the concentrated stress of the partially-damaged pipe bodies due to the impact is eliminated, and the material property and the mechanical property are not changed; through flaw detection, all the pipe bodies are qualified and achieve the use requirements; and the concave pit returning device is simple, convenient, safe and reliable to operate, has small volume and can be moved at random.
Description
Technical field
The utility model relates to metal pipe material shape corrections device in the field, oil field, refers in particular to a kind of pit return mechanism.
Background technology
Have bad luck in loading and unloading that metal pipe material is prone to flexural deformation or pit phenomenon in the process.Can go alignment with straightener to flexural deformation, go reply but the phenomenon of body pit never has effective way, making the raw material body pit occur can not normally use, and produces waste.The research of pit recovery device will effectively restore to the original state irregular pit body exactly, reaches the production instructions for use; Reduce the raw material loss to greatest extent.
The utility model content
There is the out of use problem of pit in order to solve existing metal pipe material body
,The utility model provides a kind of pit return mechanism, and this pit return mechanism adopts variable arc chord angle collet, top cap, and beneficial effect is: stressed even, accurate positioning is applicable to the plurality of specifications body; The artificial hydraulic pressure power source, transmission of power is even, and stroke is short, and speed is fast, and energy consumption is low, and is pollution-free, and normal temperature operation more than 0 ℃ meets national low-carbon environment-friendly requirement fully; The body small rut can restore to the original state, and it is smooth and easy that especially big pit recovers the back latus rectum, eliminates the concentrated stress that local impaired body causes because of impact, and material material, mechanical performance do not change, and be all qualified through flaw detection, reaches instructions for use; Easy and simple to handle, safe and reliable, small and exquisite flexible, arbitrarily mobile.
The utility model solves the technical scheme that its technical problem adopted: a kind of pit return mechanism; Mainly comprise circular arc jacking and hydraulic cylinder, circular arc top, positioning rule, fixed mount, backstay, set bolt, hydraulic oil pipe, hand-hydraulic station, draw bar; It is characterized in that: the circular arc top is installed on circular arc jacking and the hydraulic cylinder; Installing and locating chi on the backstay, fixed mount connects backstay, and backstay is fixed on the draw bar through set bolt; Hydraulic oil pipe is communicated with hand-hydraulic station and circular arc jacking and hydraulic cylinder, and draw bar is fixedly connected with hydraulic cylinder with the circular arc jacking.
The beneficial effect of the utility model is that stressed even, accurate positioning is applicable to the plurality of specifications body; The artificial hydraulic pressure power source, transmission of power is even, and stroke is short, and speed is fast, and energy consumption is low, and is pollution-free, and normal temperature operation more than 0 ℃ meets national low-carbon environment-friendly requirement fully; The body small rut can restore to the original state, and it is smooth and easy that especially big pit recovers the back latus rectum, eliminates the concentrated stress that local impaired body causes because of impact, and material material, mechanical performance do not change, and be all qualified through flaw detection, reaches instructions for use; Easy and simple to handle, safe and reliable, small and exquisite flexible, arbitrarily mobile.
Description of drawings:
Fig. 1 is the utility model fundamental diagram.
Fig. 2 is the utility model hydraulic schematic diagram
1. tubing among the figure, 2. circular arc jacking and hydraulic cylinder, 3. circular arc top, 4. positioning rule, 5. fixed mount, 6. backstay, 7. set bolt, 8. hydraulic oil pipe, 9. hand-hydraulic station, 10. body pit, 11. draw bars.
The specific embodiment:
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
A kind of pit return mechanism; Mainly comprise circular arc jacking and hydraulic cylinder 2, circular arc top 3, positioning rule 4, fixed mount 5, backstay 6, set bolt 7, hydraulic oil pipe 8, hand-hydraulic station 9, draw bar 11; It is characterized in that: circular arc top 3 is installed on circular arc jacking and the hydraulic cylinder 2; Installing and locating chi 4 on the backstay 6, fixed mount 5 connects backstay 6, and backstay 6 is fixed on the draw bar 11 through set bolt 7; Hydraulic oil pipe 8 is communicated with hand-hydraulic station 9 and circular arc jacking and hydraulic cylinder 2, and draw bar 11 is fixedly connected with hydraulic cylinder 2 with the circular arc jacking.
The operation principle of pit return mechanism: shown in accompanying drawing 1, before the work fix draw bar 11 and circular arc collet and hydraulic cylinder 2, backstay 6 is connected through set bolt 7 with draw bar 11 and is fixing then.Drive circular arc collet and hydraulic cylinder 2 and circular arc top 3 by draw bar 11 after previous work is accomplished and stretch to tubing 1 inside; Swing on tubing 1 by the 5 control backstays 6 of the fixed mount on the backstay 6 then, accurately navigate to body pit 10 places by the positioning rule on 6 backstays 4 again.Import the liquid oil pipe into by 9 pressurizations of hand-hydraulic station; After the pressure of hydraulic oil pipe 8 imports circular arc collet and hydraulic cylinder 2 into,, make body pit 10 by hydraulic cylinder jack-up circular arc top 3; Reinstatement is pulled out circular arc collet and hydraulic cylinder 2 and circular arc top 3 by draw bar 11 after work is accomplished again.
The beneficial effect of this pit return mechanism is that stressed even, accurate positioning is applicable to the plurality of specifications body; The artificial hydraulic pressure power source, transmission of power is even, and stroke is short, and speed is fast, and energy consumption is low, and is pollution-free, and normal temperature operation more than 0 ℃ meets national low-carbon environment-friendly requirement fully; The body small rut can restore to the original state, and it is smooth and easy that especially big pit recovers the back latus rectum, eliminates the concentrated stress that local impaired body causes because of impact, and material material, mechanical performance do not change, and be all qualified through flaw detection, reaches instructions for use; Easy and simple to handle, safe and reliable, small and exquisite flexible, arbitrarily mobile.
