Abstract
The utility model belongs to the technical field of equipment for producing oil country tubular goods, and particularly relates to a centering device of a full-automatic oil pipe press testing device. The centering device of the full-automatic oil pipe press testing device comprises a base, wherein two support bodies are arranged on the base in an opposing way, hydraulic cylinders are arranged on the support bodies, a guide wheel stand is arranged at the front end of the piston rod of each hydraulic cylinder, a guide wheel is arranged on the guide wheel stand, and circular arc-shaped sinks are formed on the surface of the guide wheel. The centering device provided by the utility model is reasonable in structural design and has a better oil pipe centering effect.
Description
Technical field
The utility model belongs to oil country tubular goods production equipment technical field, relates in particular to a kind of Full automatic oil pipe pressure testing machine centralising device.
Background technology
Because the applied environment of oil country tubular goods is more abominable, in the environment of underground High Temperature High Pressure severe corrosive, easily damage.Therefore, must carry out pressure testing for the oil country tubular goods finished product, detect the voltage endurance capability of tubing, tubing defective is rejected, reduce to greatest extent the harm that it brings.Existing oil pipe pressure tester generally comprises pressurizing point, water filling device, plugging device and conveying arrangement etc., owing to lacking centralising device, water filling port and shutoff port are difficult to aim at the two ends of tubing, so just need to manually assist.
The utility model content
The utility model provides a kind of reasonable in design, the effective centralising device that is used for Full automatic oil pipe pressure testing machine of centering for solving the technical matters that exists in the known technology.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is: the Full automatic oil pipe pressure testing machine centralising device comprises base, on this base, relatively be provided with two supporters, be equipped with hydraulic jack at described supporter, the front end of the piston rod of described hydraulic jack is provided with wheel stand, be provided with guide wheel at described wheel stand, the surface of described guide wheel has the depression of circular arc.
Advantage of the present utility model and good effect are: the utility model reasonable in design is easy to production and processing.The guide wheel of hydraulic jack and front end is inwardly motion synchronously, tubing clamp is located at wherein and does not hinder oil pipe motion vertically, and centering is effective.
Preferably: described hydraulic jack is fixed on the described supporter by pressing plate and screw.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, protective cover; 2, supporter; 3, hydraulic jack; 4, base; 5, guide wheel; 6, wheel stand.
Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
See also Fig. 1, the utility model comprises base 4, relatively is provided with two supporters 2 on this base 4.
Be equipped with hydraulic jack 3 at supporter 2, for the ease of dismounting and maintenance, hydraulic jack 3 is fixed on the supporter 2 by pressing plate and screw.
The front end of the piston rod of hydraulic jack 3 is provided with wheel stand 6, is provided with guide wheel 5 at wheel stand 6.
The surface of guide wheel 5 has the depression of circular arc, and its radian should equal the surperficial radian of oil pipe.
The course of work of this example: the middle part that this centralising device is installed on oil pipe pressure tester by base 4, oil pipe is from one section material loading, and front end passes between two guide wheels 5, primer fluid compressing cylinder 3, two guide wheels 5 move inward under the drive of piston rod, until hold out against the sidewall of oil pipe.After pressure testing is finished, close hydraulic jack 3, oil pipe can freely be withdrawn from.
Claims (2)
