Abstract
Disclosed is a switching sleeve for a hydraulic telescoping ram main body and a hydraulic telescoping ram of a density probe in the petroleum logging field, comprising a rocker support (1), an integral type switching sleeve (2), a split type screw thread ring (3), a pin (4), a bearing plug (5) and a screw (6). The rocker support (1) is connected with the integral type switching sleeve (2) through the screw (6). The split type screw thread ring (3) is connected with the integral type switching sleeve (2) and is fixed through the pin (4). The integral type switching sleeve (2) is provided with the bearing plug (5) which only needs to replace the screw thread ring (3) without need of disassembling the hydraulic system. Thus the work efficiency and the anti-shear ability of the switching sleeve are greatly improved.
Description
Technical field
The utility model relates to the reducing sleeve in a kind of hydraulic sidewall contact device that uses in the oil well logging field, is used for hydraulic sidewall contact device main body and being connected that density is popped one's head in.
Background technology
Hydraulic sidewall contact device can satisfy the needs of logging instrument bore hole well loggings such as lithology and density logging, compensation density and focus type microballoon.Reducing sleeve is the structural member that hydraulic sidewall contact device is connected with probe.Because will repeatedly change probe during actual the well logging, the frequency of utilization of reducing sleeve is very high, the threaded connector spoilage in the reducing sleeve will raise.Similarly the syndeton of hydraulic sidewall contact device and probe adopted separate form mostly in the past, in case the part that is threaded is damaged, hydraulic sidewall contact device all need be dismantled, and workload is quite big.Field maintenance is inconvenience very, influences the field operation progress.Split type reducing sleeve anti-shear ability is poor simultaneously, and instrument reliability is poor.
Summary of the invention
The purpose of this utility model provides the novel hydraulic telescoping ram reducing sleeve that use in a kind of oil well logging field, and it only needs to change threaded collar, need not to dismantle hydraulic system.Increase work efficiency greatly.Can effectively improve simultaneously the anti-shear ability of reducing sleeve.
The utility model is achieved in that and comprises rocker arm support 1, monolithic reducing sleeve 2, split type threaded collar 3, pin 4, pressure-bearing plug 5, screw 6; rocker arm support 1 links to each other with monolithic reducing sleeve 2 by screw 6; split type threaded collar 3 is connected with monolithic reducing sleeve 2; split type threaded collar 3 usefulness pins 4 are fixing, are provided with pressure-bearing plug 5 in the monolithic reducing sleeve 2.
4 screws 6 of rocker arm support 1 usefulness link to each other with monolithic reducing sleeve 2.
Advantage of the present utility model is: the utility model need not rocker arm support 1 and 5 dismountings of pressure-bearing plug when changing split type threaded collar 3, avoided draining the oil and bonding wire, simplified working programme, monolithic reducing sleeve 2 effectively improves shear resistance simultaneously, has improved the reliability of instrument greatly.
Description of drawings
Accompanying drawing 1 is a main TV structure schematic diagram of the present utility model;
Accompanying drawing 2 be the utility model A-A to the sectional structure schematic diagram;
Accompanying drawing 3 is the mounting structure schematic diagram of the utility model screw 6.
The specific embodiment
As shown in Figure 1, comprise rocker arm support 1, monolithic reducing sleeve 2, split type threaded collar 3, pressure-bearing plug 5; rocker arm support 1 links to each other with monolithic reducing sleeve 2, split type threaded collar 3 is connected with monolithic reducing sleeve 2, is provided with pressure-bearing plug 5 in the monolithic reducing sleeve 2.
As shown in Figure 2, split type threaded collar 3 usefulness pins 4 are fixing.
As shown in Figure 3,4 screws 6 of rocker arm support 1 usefulness link to each other with monolithic reducing sleeve 2.
The utility model is made up of rocker arm support 1, monolithic reducing sleeve 2, split type threaded collar 3, pin 4, pressure-bearing plug 5 and screw 6; 4 screws 6 of rocker arm support 1 usefulness link to each other with monolithic reducing sleeve 2; monolithic reducing sleeve 2 is connected with the density probe by split type threaded collar 3 is installed; split type threaded collar 3 usefulness pins 4 are fixing; when the generation threaded collar is damaged; directly change split type threaded collar 3 and get final product, adopt monolithic reducing sleeve 2 can effectively improve shear strength.
Claims (2)
1. novel hydraulic telescoping ram reducing sleeve, comprise rocker arm support (1), monolithic reducing sleeve (2), split type threaded collar (3), pin (4), pressure-bearing plug (5), screw (6), it is characterized in that: rocker arm support (1) links to each other with monolithic reducing sleeve (2) by screw (6), split type threaded collar (3) is connected with monolithic reducing sleeve (2), split type threaded collar (3) is fixing with pin (4), is provided with pressure-bearing plug (5) in the monolithic reducing sleeve (2).
