Abstract
The utility model discloses a portable quick piston moving device. The portable quick piston moving device comprises two semicylindrical snap rings which are identical in size, one ends of the two snap rings are mutually hinged while the other ends of the same are connected via a fastening bolt, the two snap rings form a cylinder after being fastened together, and one of the snap rings is provided with an air inlet. The snap rings can snap a mud opening of an air cylinder so as to pressurize a balance piston, so that the balance piston is enabled to return to an initial position quickly. In addition, the portable quick piston moving device is simple in structure and convenient to carry.
Description
Technical field
The utility model is the device that uses in a kind of oil well logging instrument, particularly, relates to a kind of portable piston quick moving device.
Background technology
As described in Figure 1, dummy piston 1 is the critical component of little electric the approximate ratio of the circumference of a circle to its diameter as calculated by Zu Chongzhi i.e. between 3.1415926 and 3.1415927 scanning and imaging logging instrument, for reliability and the life-span of improving dummy piston 1, increased the design of wear ring and mud-scraping ring 2 during design on dummy piston 1, but this has also increased dummy piston 1 that wear ring and mud-scraping ring 2 are housed and the frictional force between piston rod 3, make instrument after maintaining during oiling dummy piston 1 can not get back to initial position, affect oiling and the circulation of instrument; For the ease of the turnover of mud, mud mouth 1 designs greatlyr, is not easy to push back piston from mud mouth 1 simultaneously.
The utility model content
In order to solve the problems of the technologies described above, the utility model discloses a kind of portable piston quick moving device, can make dummy piston get back to rapidly initial position.
The disclosed portable piston quick moving device of the utility model, the snap ring that comprises two semicircle tubulars that two sizes are identical, one end of two snap rings is hinged, the other end is connected by clamping bolt, form a cylinder after described two snap rings fasten, be provided with air inlet on one of them snap ring.
Preferably, described portable piston quick moving device also comprises two rubber gaskets, described two rubber gaskets fit tightly with the inwall of described two snap rings respectively, and the through hole relative with described air inlet is set on the rubber gasket that the inwall of described snap ring with air inlet is set is fitted.
Preferably, described portable piston quick moving device also comprises brace, and an end of described two snap rings is connected with described brace by pin respectively.
Preferably, described portable piston quick moving device also comprises hinge, and an end of described two snap rings is fixedly connected with two hinges of described hinge respectively.
The mud mouth that two snap rings of the present utility model can block cylinder balances piston pressurization, makes dummy piston get back to rapidly initial position, and simple in structure, is easy to carry.
Description of drawings
Fig. 1 is the part-structure schematic diagram of microresistivity scanning and imaging logging instrument in prior art;
Fig. 2 is the structural representation of portable piston quick moving device in the utility model embodiment.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, hereinafter in connection with accompanying drawing, embodiment of the present utility model is elaborated.Need to prove, in the situation that do not conflict, the feature in the present embodiment and embodiment is any combination mutually.
In an embodiment of the present utility model, a kind of portable piston quick moving device is disclosed, as shown in Figure 2, the snap ring 1,2 that comprises two semicircle tubulars that two sizes are identical, two snap rings 1, an end of 2 are hinged, the other end is connected by clamping bolt 3, and two snap rings 1,2 fastenings form a cylinder afterwards, are provided with air inlet 9 on one of them snap ring 1.
In use, first two snap rings 1,2 are opened, snap ring 1,2 is enclosed within on piston rod, make simultaneously the air inlet port 9 on snap ring 1 aim at arbitrary mud mouths, two snap rings 1,2 that close fix two snap rings 1,2 the other end by clamping bolt 3, add air pressure by air inlet port 9 to piston rod with air gun or inflator, until dummy piston is got back to initial position, turn at last clamping bolt 3, take off two snap rings 1,2.
Further improvement as above-described embodiment, portable piston quick moving device also comprises two rubber gaskets 7,8, two rubber gaskets 7,8 fit tightly with two snap rings 1,2 inwall respectively, and on rubber gasket 7 that the inwall of the snap ring 1 that air inlet 9 is set is fitted, the through hole 10 relative with air inlet 9 are set.Rubber gasket 7,8 can increase snap ring 1,2 and cylinder between seal, improve the effect of pressurization.
In the above-described embodiments, two snap rings 1,2 can adopt various ways hinged, for example, 4, two snap rings 1 of brace can be set on portable piston quick moving device, an end of 2 is connected with brace 4 by pin 5,6 respectively.
As the embodiment that can be out of shape, also hinge (not shown in Fig. 2) can be set on portable piston quick moving device, two snap rings 1, an end of 2 are fixedly connected with two hinges of hinge respectively.
Although the disclosed embodiment of the utility model as above, the embodiment that described content just adopts for the ease of understanding the utility model is not to limit the utility model.Technician under any the utility model in technical field; under the prerequisite that does not break away from the disclosed spirit and scope of the utility model; can do any modification and variation what implement in form and on details; but scope of patent protection of the present utility model still must be as the criterion with the scope that appending claims was defined.
