In Fig. 1, Fig. 2, the flow process of tank car inwall characterization processes of the present invention is very simple than the prior art scheme, convenient, has overcome the problem that prior art exists.
In Fig. 3, Fig. 4, Fig. 5, Fig. 6, one embodiment of the present of invention are to have adopted following technical scheme and equipment.
This tank car detection equipment of inner wall is by support 1, rotary disk 2, by motor-driven rotary reducer 3, be made up of motor-driven stepless speed adjusting gear 4, screw rod 5, slide bar 6, slide block 7, fork arm group 8, lead 9, illuminating lamp 10, image sensor 11 (CCD), track 12, motor lifter 13, wire rope 14, tank car 15, computer control system.
At Fig. 5, among Fig. 6, by track 12,14 pairs of cars of motor lifter 13 and wire rope, support 1 is installed on the hand-hole of tank car 15, install back rotating disk 2 on the support 1, rotary disk 2 can be done gyration under rotary disk speed reduction unit 3 drives, adorning stepless speed adjusting gear 4 above the rotary disk 2, rotary disk 2 bottoms are stretched in the tank car 15, screw rod 5 is equipped with in rotary disk 2 bottoms, slide bar 6, slide block 7, fork arm group 8, fork arm group 8 one ends are hinged to be suspended on the rotary disk 2, and the axis pin base that connects fork arm group 8 on the rotary disk 2 is with 8 supportings of fork arm group, and fork arm group 8 can be single-row, also can be biserial, the other end of fork arm group 8 is hinged to be suspended on the slide block 7, but stepless speed adjusting gear 4 drive screws 5 just, counter-rotating, screw rod 5 drives on the slide block 7, move down, thereby driving fork arm group 8 is stretched out or is shunk, and drives camera (CCD) 11 and moves reciprocatingly at tank car 15 centers.Lead 9 send electricity and transmission signals to camera (CCD) 11 and illuminating lamp 10, and camera (CCD) 11 is finished the shooting task.
In Fig. 3 and Fig. 4, utilize this equipment can realize that computing machine detects and control automatically.Computer console mainly contains PC and programming controller is formed, and is installed in the pulpit, and the CZOOH Programmable Logic Controller is by program software control chart image sensor (CCD).In order to realize that many checkout equipments control simultaneously, can utilize the application program and the control chart image sensor (CCD) of computer system by computing machine and data transmission interface; The realization tank car is the position in tank car to car and control chart image sensor (CCD).
In Fig. 3, Fig. 4, the operation of tank car automatic detection device is given: tank car is to jar: a row tank car enters platform, and testing agency moves to make at track 12 aims at a jar center to the car feed mechanism.Image sensor (CCD) 11 and illuminating lamp 10 are loaded fork arm group 8 leading portions, by the car feed mechanism is contained in support 1 on the tank car hand-hole, by position and the orientation of computer console control chart image sensor CCD in tank car, comprehensive monitoring is carried out in tank car inside, and figure signal in the tank car collected on the computing machine LCD monitor, can judge by computing machine or manual observation comparison whether tank car needs to clean.Image sensor CCD and illuminating lamp can adopt the project organization of corresponding explosion proof ratings.In order to realize that computing machine detects automatically, in computing machine, pass through at the bottom of the corresponding image of graph data library storage and gas spectrogram shape and the tank car master copy and the normal condition collection of illustrative plates, by detected image in scene or figure are compared with it, if the normal conditions of not reaching, can clean, also can add simultaneously manually on display screen, to observe and judge relatively whether tank car needs to clean.
In addition, in order to realize checkout equipment is accurately controlled and reduced the weight and volume of equipment, the reduction gear that connects with motor can adopt harmonic wave drive speed reducer, accurately controls the vertical and horizontal shift of feed mechanism by the rotating speed and the revolution of program controlled motor and speed reduction unit.
Present developing rapidly of wireless transmission and Computer Control Technology can realize very easily that by the unify data transmission and processing unit that adopts wireless transmission protocol of department of computer science multipoint wireless controls.As " bluetooth " the wireless data transmission protocols of having used at present.
The application of this device in tank car self-verifying work will produce tangible economic benefit and social benefit.With certain petrochemical plant is example, 80,000 of annual carwash total amounts, 4.8 ten thousand on disposable vehicle; Shown in economic benefit sees the following form:
By last table analysis as seen:, only compare this petrochemical plant with former technology and can save 1,130,000 yuans every year if use the tank car check system.Family's tank washing point surplus the whole nation has 300 now, if all use this check system, economic benefit is very surprising.If have 1,000,000 disposable tank cars to calculate every year by the whole nation, can save cleaning charge every year with 2,354 ten thousand yuan.
| Annual disposable car amount | ????48000 | ????48000 |
| Annual total expenses | 115.4 ten thousand yuan | 2.78 ten thousand yuan |
From the social benefit angle analysis, in atmosphere, discharge 60 cubic metres of chemical industry or the calculating of oil product gas by each tank car, be example with certain general petrochemicals factory, annual 4.8 ten thousand disposable tank cars are just to airborne release 288 ten thousand stere poisonous fumes.If use a jar interior check system, discharging waste gas has only 1% of former cleaning discharging, only this item, and annual this factory can reduce toxic emission 285 ten thousand steres.If have 1,000,000 disposable tank cars to calculate every year by the whole nation, toxic emission 5938 ten thousand steres can be reduced in the annual whole nation.The more important thing is and eliminated the hidden danger that the workman poisons.
