Technical field
The application relate to that top, a kind of well control workshop pressure testing hole uses for stopping the erosion control cover plate that pressure testing part flies out.
Background technique
" should be placed in pressure testing hole by test specimen, water-stop, each one of hermetic seal pressure testing hole according to 2.3.3.2 bar regulation in China PetroChemical Corporation's " (gas) well control workshop qualification grade standard of recovering the oil ".The degree of depth in pressure testing hole is not less than 5m, by test specimen top lower than mill floor 2m, and top, pressure testing hole equipment mobile protective lid, and meet the requirement that pressure testing detects operation.Pressure testing hole surrounding the protective grating being not less than 1.2 meters should be installed " requirement, pressure testing hole top install erosion control cover plate additional, to stop that pressure testing part flies out, ensure personal safety.
In prior art, erosion control cover plate has no relevant report.
Summary of the invention
The object of the application builds one to be placed in top, pressure testing hole, by closing cover plate during pressure testing, stopping that pressure testing parts fly out and causing personal injury, reduce the pressure testing hole checking motion of operating risk when workmen constructs.
The object of the application is achieved in that pressure testing hole checking motion comprises covering one, two, three near coal-mine cover plate of pressure testing, and in order to drive the drive unit of one, two, three cover plate.One, two, three slide rail of arranging up and down is provided with above described pressure testing hole is near coal-mine, slide respectively in one, two, three slide rail described and be connected with one, two, three cover plate, one, two, three cover plate head and the tail overlap joint, lap-joint is provided with contiguous block, and described one-level cover plate is driven by drive unit.
Owing to carrying out technique scheme, the invention solves test component in High-Voltage Testing Process, fly out the risk caused personal injury accidents, and ensure that pressure testing job safety, and then ensure workmen's personal safety.The application by the stretching, extension successively of three sections of cover plates, thus reaches and covers the near coal-mine object of pressure testing, and pulled by mutual in three sections of cover plate stretching process, expansion process is comparatively steady.The application's structure is relatively simple, utilizes reducing motor to drive, can complete fast and cover and opening procedure.
Accompanying drawing illustrates: the technological scheme of the application is provided by the following drawings and embodiment
Fig. 1 is pressure testing hole checking motion structural representation;
Fig. 2 is one, two, three cover plate and one, two, three corresponding with it rail structure schematic diagram in the checking motion of pressure testing hole.

Embodiment
Embodiment: as shown in Figure 1, pressure testing hole checking motion comprises covering one, two, three near coal-mine cover plate 10,9,7 of pressure testing, and in order to drive the drive unit of one, two, three cover plate 10,9,7.One, two, three slide rail 6,5,4 of arranging up and down is provided with above described pressure testing hole is near coal-mine, slide respectively in one, two, three slide rail 6,5,4 described and be connected with one, two, three cover plate 10,9,7, one, two, three cover plate 10,9,7 head and the tail overlap joint, lap-joint is provided with contiguous block 8, and described one-level cover plate 10 is driven by drive unit.
Arrange the column to downward-extension at three grades of cover plates 7 towards reducing motor 1 side, described column lower end is concordant with one-level cover plate 10.
Described drive unit comprises reducing motor 1, the driving sprocket wheel 2 driven by reducing motor 1, described driving sprocket wheel 2 is arranged on the near coal-mine side of pressure testing, the near coal-mine opposite side of pressure testing is provided with driven sprocket 12, chain is equiped with between driving sprocket wheel 2 and driven sprocket 12, described chain two ends are fixedly linked with one-level cover plate 10 two ends respectively, thus one-level cover plate 10 can be pulled to slidably reciprocate in one-level slide rail 6 by reducing motor 1.Near driving, driven sprocket 2,12 place is equiped with position limit switch 11, position limit switch 11 is connected with reducing motor 1 circuit, and after the column of one-level cover plate 10 or three grades of cover plate 7 sides touches position limit switch 11, reducing motor 1 stops operating.
In one, two, three slide rail 6,5,4 described, both sides are equiped with roller 15, one, two, three cover plate 10,9,7 lower end surface and roller 15 Structure deformation.One, two, three cover plate 10,9,7 lower end surface is provided with carrier bar 14.Add upper ledge at one-level slide rail 6 upper end and strengthen channel-section steel 13.Be covered with shell 16 at one, two, three slide rail 6,5,4, play supplemental support, fixing effect.
During unlatching, nethermost one-level cover plate 10 starts to open, when one-level cover plate 10 and secondary cover plate 9 side by side time, one-level cover plate 10 is connected with the contiguous block of secondary cover plate 9, and drive secondary cover plate 9 moves.When secondary cover plate 9 and three grades of cover plates 7 move to side by side, secondary cover plate 9 is connected with the contiguous block of the 3rd cover plate 19, and drive three grades of cover plates 7, until three grades of cover plates 7 bump against limitation travel switch 11, reducing motor 1 stops operating.Otherwise time closed.One signal receiver 3 can be set in this application, thus in order to the start and stop of Remote reducing motor 1, this not this Applicant's Abstract graph inventive point, concrete structure is not described in detail at this.
Above technical characteristics constitutes the most preferred embodiment of the application, has best implementation result, can meet the visual effect of valve switch.
