Testing table comprises the fixed support that is fixed on the turntable, the turnover bracket that is connected with fixed support by trip shaft; The turnover bracket upper end is fixedly connected to be useful on sealing liquid gasification steel cylinder bottle neck and to be with manometric packoff, and the lower end is slidingly fitted with the steel cylinder pallet;
Described packoff is connected with the tracheae of band cross-over valve and the water pipe of band cross-over valve; Wherein the water pipe with cross-over valve connects two branch branching pipes by cross-over valve, and a branch branching pipe is connected with the water under high pressure press pump, and another branch branching pipe is connected with self-priming pump;
Also comprise vertical setting and the oil cylinder that is connected with Hydraulic Station by oil pipe, its upper end is connected the trip shaft upper end, and the lower end is connected with the steel cylinder pallet.
Gas-holder also is installed on turntable; Gas-holder is connected with upset cylinder on being arranged on fixed support by tracheae; Described upset cylinder and described trip shaft are in transmission connection.
Good effect of the present invention is: cylinder for liquefied gas is finished the hydraulic testing automatically on turntable, and the process of the test turntable of finishing the work just in time rotates a week.So a people is responsible for changing bottle, all the other actions have all realized automation mechanized operation.
Through the test of many times statistics, the cylinder for liquefied gas hydraulic testing is brought up to 2400 of per tour by original per tour (8hr) 600 (steel cylinders).And alleviated operator's labour intensity significantly.Process of the test is standard more, and test findings is more reliable.
(4), description of drawings
Fig. 1 is the structural representation of turntable of the present invention.
Fig. 2 is the structural representation of testing table of the present invention.
(5), embodiment
The invention will be further described below in conjunction with specific embodiment.
As Fig. 1, this example comprises a horizontally disposed discoid turntable 9, and turntable 9 has the central shaft mechanism 3 that is connected with its installation station.Below turntable 9, be provided with the pond.The favourable turn certainly 5 that is used to drive the turntable rotation is installed on turntable 9, and this is made a connection certainly and 5 comprises motor and the speed reduction unit that is connected with drive of motor, and speed reduction unit is by 3 work of gear drive central shaft mechanism, 9 rotations of drive turntable.
At turntable 9 near the testing table 1 that several are used to test steel cylinder hydraulic pressure upwards is installed in outer peripheral position week.As shown in Figure 2, testing table 1 comprises the fixed support 16 that is fixed on the turntable 9, the turnover bracket 17 that is connected with fixed support 16 by trip shaft 18.Turnover bracket 17 upper ends are fixedly connected to be useful on sealing liquid gasification steel cylinder bottle neck and with the packoff 12 of tensimeter 10, the lower end is slidingly fitted with steel cylinder pallet 15.Tested cylinder for liquefied gas 14 is installed between packoff 12 and the steel cylinder pallet 15.
Described packoff 12 is connected with the exhaust pressure relief pipe of band exhaust pressure relief valve and the water pipe of band cross-over valve; Wherein connect two branch branching pipes with the water pipe of cross-over valve by cross-over valve, branch branching pipe is connected with water under high pressure press pump 2 on turntable 9, and another branch branching pipe is connected with self-priming pump 8 on turntable 9.
Testing table 1 also comprises vertical setting and the oil cylinder 11 that is connected with Hydraulic Station 4 by oil pipe, and its upper end is connected trip shaft 18 upper ends, and the lower end is connected with steel cylinder pallet 15.
Gas-holder 7 also is installed on turntable 9; Gas-holder 7 is connected with upset cylinder 13 on being arranged on fixed support 16 by tracheae.Described upset cylinder 13 is in transmission connection with described trip shaft 18, drive trip shaft 18 during 13 work of upset cylinder and rotate, and then the cylinder for liquefied gas 14 that drives on turnover bracket 17 and the turnover bracket 17 is done 180 ° of upsets around trip shaft 18.
The panel box 6 of numerical control form also is installed on turntable 9.
Principle of work of the present invention is as follows:
1), turntable 9 slowly rotates, oil cylinder 11 guide rods stretch out, steel cylinder pallet 15 falls, and loads onto cylinder for liquefied gas 14, and packoff 12 lower ends are installed in the bottle neck of cylinder for liquefied gas 14.
2), press the switch of oil cylinder 11, oil cylinder 11 guide rods retraction drives that cylinder for liquefied gas 14 rises and compacted.
3), self-priming pump 8 is by dividing branching pipe and packoff 12 water filling to cylinder for liquefied gas 14 in, the exhaust pressure relief pipe is with air discharge in the bottle simultaneously.
4), close the exhaust pressure relief valve, water under high pressure press pump 2 is annotated in cylinder for liquefied gas 14 by minute branching pipe and packoff 12 and is stopped filling automatically after water under high pressure reaches set pressure (force value reads from tensimeter 10).
5), pressurize is 30 seconds.
6), the work of upset cylinder 13, drive turnover bracket 17 and do 180 ° of upsets, open the pressure release of exhaust pressure relief valve simultaneously, the water in the cylinder for liquefied gas 14 are put into the pond do recycling.
7), water puts clean back turnover bracket 17 and does 180 ° of upsets, cylinder for liquefied gas 14 is righted, and takes off steel cylinder and another steel cylinder to be measured is put on this testing table.
Finish above-mentioned Work turning table 9 and just in time rotate a week.
