Abstract
The utility model discloses a cap locator is pressed to oil well packing box, include that two semicircular are used for holding tightly the slips of polished rod, tile and the affiliated card tile of giving first place to respectively, the articulated of self both ends is do not carried out with two pins to main slips and affiliated card watt -minute. Radially set up a screw hole on main tile or the affiliated card tile, the threaded hole mounting adjustment screw. Main slips or affiliated card tile be the one end connection screw lantern ring wherein, turnbuckle intra -annular installation fastening screw. Still include nut set section of thick bamboo spanner, nut set section of thick bamboo spanner cover is on fastening screw. The utility model discloses the locator is used repeatedly many times, and the installation is dismantled, and is convenient fast. A press the cap crowded wounded, injure by a crashing object that fixes when being used for the oil well packing box to change the filler packing and lift the pressure cap on the polished rod, can effectively avoid operating personnel by the landing. improve field operation's security performance to can be by 2 3 the people operates the change and is one -man operation. It is safe convenient, improve labor efficiency.
Description
Technical field
This utility model relates to packing box pressing cap, specifically oil well packing box pressing cap localizer.
Background technology
Oil field development is exploited, by crude oil from underground by equipment such as mechanical oil recovery i.e. oil pumper-sucker rod-oil well pumps
Exploitation is to ground.In oil recovery process, production wellhead sealing packing box and eccentric abrasion prevention wellhead packing box change airtight and watertight padding
Packing is a regular maintenance work.Need to be unloaded by packing box pressing cap during operation is pushed into above polished rod, the most once
With the rope made of hemp, iron wire is tied up and fixing was the most once occurred pressure cap landing to cause to squeeze wound, the accident such as injures by a crashing object, there is bigger potential safety hazard.
The stupid way additionally using personnel to lift pressure cap then causes personnel's cross-operation, operation inconvenience and the waste of manpower.
Utility model content
The purpose of this utility model is to provide oil well packing box pressing cap localizer, and it is solid and reliable fixed to carry out packing box pressing cap
The features such as position, the most also has installation, and convenient disassembly is quick.
In order to reach above-mentioned purpose, this utility model have employed following technical scheme, oil well packing box pressing cap localizer, bag
Include two semicircular slips for holding polished rod tightly, respectively main card watt and vice card watt, described main card watt and vice card watt-minute
Do not carry out the hinged of self two ends with two pins.
Described main card watt or the upper radial direction of vice card watt offer a screwed hole, mounting and adjusting screw in screwed hole.
Screw washer is installed in described main card watt or vice card watt wherein one end.
Also include that screw cap sleeve spanner, described screw cap sleeve spanner are enclosed within fastening screw.
Described screw cap sleeve spanner is 7 fonts.
Compared to prior art, this utility model has the advantages that
This utility model localizer can repeatedly use, and installs, dismounting, rapid and convenient.Change for oil-well packing box
It is fixed on polished rod during filler packing and lifts pressure cap, operator can be prevented effectively from and squeezed wound by the pressure cap of landing, injure by a crashing object.Carry
The security performance of high execute-in-place, and can be operated by 2-3 people and be changed to one man operation.Safe and convenient, raises labour efficiency.

Detailed description of the invention
Relevant detailed description of the present utility model and technology contents, coordinate accompanying drawing to be described as follows, but accompanying drawing only provide reference
With purposes of discussion, not it is used for this utility model is any limitation as.
According to Fig. 1, oil well packing box pressing cap localizer, including two semicircular slips for holding polished rod tightly, respectively
Forming for main card watt 1 and vice card watt 3, described main card watt and vice card watt-minute do not carry out self two ends with two pins 2,5
Hinged.An adjustment screw 4 is had at vice card watt convex surface center.Described main card watt outerplanar end installs screw washer.The most also include
Screw cap sleeve spanner coordinates with bolt to play and unclamps and fixation.
This localizer is by two panels height 35mm, the major-minor slips composition of thick 6mm, long 100mm, through two by pin, one end
The alignment pin of tile is fixed and keeps two card tile foldings flexible.There is a 8mm to adjust at vice card tile convex surface center
Set screw, is used for adjusting this localizer internal clearance to be common to the fixing common polished rod packing box pressing cap of Φ 22 and Φ 42
Thermal cycle heating Polish rod packing box pressing cap, 7 word screw cap sleeve handles coordinate with fastening screw and fasten holding card and play and fixedly positioning
Effect, fastening screw rod is effectively prevented air slaking corrosion by 7 word sleeves protections all the time, and machinery collides with the effect of leading screw.7
Word sleeve handle can rotation the most suitable, counterclockwise play parbuckle screw switch holding card function.
When changing packing box filler packing pressure cap unloaded and be upwards pushed into about 50cm and be in below pressure cap, on polished rod, this be installed
Device.During as it can be seen, install, this localizer is fixed on the polished rod below packing box pressing cap, by adjusting pair
Slips 3 cambered surface centralized positioning screw reaches to closely cooperate with polished rod gap.Then 7 font screw cap sleeve spanner up times are adjusted
Pin rotates and localizer can be fixed on the polished rod below packing box pressing cap.
The foregoing is only preferred embodiment of the present utility model, be not used to limit the scope of the claims of the present utility model, other
Use the equivalence change of patent spirit of the present utility model, all should all belong to the scope of the claims of the present utility model.
