The present invention, in order to solve the problem of prior art, provides one and manufactures oil drum bucket wall automatic leak-checking device again, solves helium mass spectrometry technology leak detection cost high, the problem that overall production efficiency is low.
Technical solution of the present invention is as follows: one manufactures oil drum bucket wall automatic leak-checking device again, comprise carrying oil drum and make the monitor station that its circumference is rotated and the detecting device that can move axially along oil drum, described detecting device comprises and is oppositely arranged permanent magnet and magneto-dependent sensor, be provided with gap between described permanent magnet and magneto-dependent sensor, the bucket wall of oil drum is placed in described gap.
Further, the oil drum being applicable to multiple different-diameter is leaked in order to make this detection, described monitor station comprises the motor of pallet and driving tray rotation, described pallet is provided with some claws and radial slideway, described claw slides in described radial slideway, described claw comprises the claw platform, fixed claw and the movable claw that coordinate with described radial slideway, described fixed claw is fixedly installed on described claw platform, described movable claw and fixed claw are oppositely arranged, and regulate the spacing of described movable claw and fixed claw by screw mandrel.
Preferably, the side of described fixed claw relative motion pawl arranges strain gauge, and the oil drum bucket wall pressure power that fixed claw described in described strain gauge perception is subject to also controls described screw mandrel action.
Further, in order to make this leakage detection apparatus carry out continuous detecting, the described oil drum bucket wall automatic leak-checking device that manufactures again also comprises ground surface platform, and described ground surface platform is provided with guide rail and cantilever, described monitor station can move along described guide rail, and described detecting device to be arranged on cantilever and to move up and down.
In one particular embodiment of the present invention, described cantilever comprises column and crossbeam, and described column is fixedly installed on described ground surface platform, and described crossbeam to be connected with described column by screw pair and to move horizontally.
In another specific embodiment of the present invention, described cantilever comprises column and crossbeam, and described column is fixedly installed on described ground surface platform, and described detecting device is arranged on also can along cross beam movement on crossbeam.
The course of work manufacturing oil drum bucket wall automatic leak-checking device is again such, detecting device stretches into bottom oil drum, oil drum rotates under pallet drives, detecting device carries out upward vertical movement, detecting device is that helical wire form scans whole bucket wall with this at oil drum bucket wall moving line, in whole process, magneto-dependent sensor does not have perception magnetic field of permanent magnet to send signal then to illustrate that barrel wall is intact, otherwise illustrates that bucket wall exists leak source.
The advantage of technical scheme provided by the present invention is, utilizes magnetic field detection to compare helium mass spectrometry technology leakage detection apparatus structure simply to detect leak source, closing the lid and lower cover, saving production cost without the need to adding for oil drum; Do not need to carry out detection by the software of complexity to judge, do not need before every task to carry out outside reference position or the demarcation of key position, there is higher work efficiency; Utilizing slide rail to move oil drum to detecting station, coordinating multiple monitor station to realize Aulomatizeted Detect.

Embodiment
Below in conjunction with embodiment, the invention will be further described, but not as a limitation of the invention.
Refer to Fig. 1 to Fig. 4, disclosed in the present embodiment, manufacture oil drum bucket wall automatic leak-checking device again, comprise ground surface platform 1, monitor station 2 and detecting device 3.Be provided with guide rail 11 and cantilever 12 in ground surface platform 1, cantilever 12 comprises column 12a and crossbeam 12b, and column 12a is fixedly installed in ground surface platform 1.Monitor station 2 is for carrying oil drum 4 and making its circumference rotate, and it coordinates can slide along guide rail 11 with the guide rail 11 of ground surface platform 1.Monitor station 2 comprises the motor 22 of pallet 21 and driving tray 21 rotation, and pallet 21 is provided with some claws 23 and radial slideway 24, and claw 23 slides according to oil drum 4 radius in radial slideway 24.Claw 23 comprises the claw platform 23a, fixed claw 23b and the movable claw 23c that coordinate with radial slideway 24, fixed claw 23b is fixedly installed on claw platform 23a, movable claw 23c and fixed claw 23b is oppositely arranged, and regulates the spacing of movable claw 23c and fixed claw 23b by screw mandrel 23d.The side of fixed claw 23b relative motion pawl 23c arranges strain gauge 23e, and when oil drum 4 is placed on claw 23, movable claw 23c pushes bucket wall to fixed claw 23b under screw mandrel 23d promotes.Oil drum 4 barrels of wall pressure power that strain gauge 23e perception fixed claw 23b is subject to, when pressure reaches the value preset, strain gauge 23e sends signal and controls screw mandrel 23d stopping action, and whole oil drum 4 is just fixed on pallet 21.
Detecting device 3 comprises and is oppositely arranged permanent magnet 31 and magneto-dependent sensor 32, and be provided with gap between permanent magnet 31 and magneto-dependent sensor 32, the bucket wall of oil drum 4 is placed in gap.Whole detecting device 3 is arranged on the crossbeam 12b of cantilever 12, and in the present embodiment, the crossbeam 12b of cantilever 12 is fixedly connected with column 12a, and detecting device 3 can move or move horizontally along crossbeam 12b vertically.But this is not necessarily arrange, also can slide rail be set between crossbeam 12b and column 12a or screw pair makes crossbeam 12b move horizontally, and detecting device 3 only can do relative to crossbeam 12b and moves vertically, finally realize the horizontal and vertical displacement of detecting device 3.
During detection, oil drum 4 is fixed on pallet 21 by claw 23, pallet 21 rotates oil drum 4 and rotates thereupon, the position of adjustment detecting device 3 horizontal direction makes oil drum 4 barrels of walls just in time be between permanent magnet 31 and magneto-dependent sensor 32, reducing detecting device 3 highly makes it be in bottom oil drum 4, then pallet 21 average rate rotate while, detecting device 3 at the uniform velocity moves up, magneto-dependent sensor 32 on oil drum 4 with the sidewall of the inswept whole oil drum 4 of helical manner.If in the process detected, it is all not leak that magneto-dependent sensor 32 is not subject to the impact of permanent magnet 31 and the sidewall that sends the whole oil drum 4 of signal instruction, and the sidewall quality of oil drum 4 is intact, can carry out simple process and reuse.Otherwise oil drum 4 needs carry out further repair work.
