Abstract
The utility model relates to a hydraulic driving radiation prevention door, which comprises an upper rail, a lower rail, a radiation preventing door and a driving mechanism. The utility model is characterized in that the driving mechanism is a hydraulic driving mechanism which adopts a hydraulic driving form. The utility model has the advantages that the service life can be enhanced by about 10 times, and the failure rate can be greatly decreased; the utility model also has the advantages of low noise, and stable and reliable operation.
Description
The utility model is the radiation protection door, is improvements over the prior art.
At the accelerator that scientific research, medical treatment, industrial flaw detection are used, Co60 machine, X-ray machine etc. can produce the place of x, γ, β ray and neutron ray, normal are equipped with special-purpose radiation-retarding door, human body are damaged preventing.And the transmission mechanism of existing radiation protection door adopts the electric gear tooth bar, or chain, lead screw transmission.The kind of drive of said structure form exists the fault rate height, noise is big, operation stability is poor, application life is short, make defectives such as difficulty is installed.
The utility model is that realization reduces noise, safety and stability is reliable and the purpose of long service life.
In order to achieve the above object, the utility model comprises rail, following rail, and radiation-retarding door and transmission mechanism is characterized in that: described transmission mechanism is a hydraulic gear.
The expansion link of the hydraulic cylinder of hydraulic gear is connected the upper end of radiation-retarding door; Or be connected the radiation-retarding door lower end.
The hydraulic cylinder of hydraulic gear is single casing or multiple casing.
The utlity model has following advantage and good effect: 1, transmission mechanism adopts the hydraulic drive form, and noise is little, and stable and reliable operation improves nearly 10 times application life, and fault rate greatly reduces.2, hydraulic gear can be gone up transmission or underdrive (being that hydraulic cylinder connects door upper end or lower end), selects flexibly, and the user can select as required, has made things convenient for the user.
Fig. 1 is a hydraulic scheme of the present utility model;
Fig. 2 is the front view of the utility model hydraulic cylinder when being multi-cylinder;
Fig. 3 is the front view of the utility model hydraulic cylinder when being single cylinder;
Fig. 4 is that the utility model hydraulic mechanism and door body are the front views when going up type of belt drive;
The front view of Fig. 5 when to be the utility model hydraulic mechanism with the door body be the underdrive form.
1, drain charge valve; 2, overflow valve; 3, three position four-way electromagnetic valve; 4, hydraulic cylinder; 5, hand-operated direction valve; 6, hand pump assembly; 7, pressure meter; 8, pressure meter switch; 9, motor; 10, gear oil pump; 11, oil cleaner; 12, go up rail; 13, following rail; 14, radiation-retarding door; 15, hydraulic gear.
Referring to Fig. 1, Fig. 2, Fig. 3, radiation-retarding door 14 is by hydraulic gear 15 transmissions.Hydraulic cylinder 4 front ends are connected door 14 upper ends.
When at closing time, shut hand-operated direction valve 5, actuating motor 9 makes gear oil pump 10 pump oil, and system pressure raises, and pressure oil enters the B oil pipe by three position four-way electromagnetic valve 3, and hydraulic cylinder 4 is stretched to a position of closing the door.
When opening the door, close hand-operated direction valve 5 equally, actuating motor 9 makes gear oil pump 10 work, and pressure oil enters the A oil pipe by three position four-way electromagnetic valve 3, and the action of opening the door is finished in hydraulic cylinder 4 withdrawals.
When having a power failure, can open hand-operated direction valve 5, just make it to be in or instead, shaking hand pump 6, finish the action of opening the door or close the door.
Referring to Fig. 4, this is the form of expansion link front end connection radiation-retarding door 14 tops of hydraulic cylinder 4, is called transmission.
Referring to Fig. 5, this is the form of expansion link front end connection radiation-retarding door 14 belows of hydraulic cylinder 4, is called underdrive.
The user can select to be suitable for upward transmission or underdrive according to the architectural feature of oneself.
The link position of hydraulic cylinder 4 and radiation-retarding door 14 can be selected according to actual conditions, as be located at positions such as reveal face, middle part or front portion.
