Abstract
The utility model relates to a drilling rod mud scraper used for the well drilling operation of petroleum ore yards, wherein an upper and a lower sets of mud scraping devices are arranged in an open type barrel body. The open type barrel body can be opened or closed so as to loosen or hold the drilling rod. The outer end of a scraper frame of the mud scraping device is connected with the open type barrel body via hinges and can be upwards pushed when the scraper frame passes through a drill rod joint with a large diameter, and the upper part of the scraper frame is pressed by a spring. A mud scraping plate is in an inner chamber of the scraper frame, and the front end of the mud scraping plate is limited by screws. The mud scraping plate is a wavy structure and has the functions of elasticity, unwinding and righting. With the self weight, the utility model can efficiently and automatically scrap the mud on the drilling rod and the joint of which the diameter is larger than the drilling rod on the same drilling rod, the utility model can conveniently change the mud scraping plates with different standards and the utility model is suitable for the mud scraping operation of various standard drilling rods. The utility model has the advantages of simple structure and high safety, and the utility model can lighten oilfield workers' labor intensity.
Description
Technical field
The utility model relates to the drilling rod of oilfield drillng operation and scrapes the mud device.
Background technology
During the oilfield drillng operation, adhering to alkaline mud on the drilling rod, drilling rod and bank head machinery such as drill pipe tong etc. are being corrosive, and bank head machinery operations such as drill pipe tong are brought influence, therefore the mud of removing on the drilling rod is very important.The joint diameter of two ends of drill is bigger than drill pipe diameter, brings certain difficulty to removing mud, and mud on the drilling rod is manually struck off in the most employing in oil field at present, and labor strength is big, and is also dangerous.
Summary of the invention
In order to change the deficiency of manually striking off mud on the drilling rod at present, the utility model provides a kind of open type drilling rod to scrape the mud device, when the oilfield drillng operation, can strike off the mud in drilling rod and the tool joint effectively automatically, and can change the cleaning shoe of different size easily, adapt to the drilling mud practice that strikes off of plurality of specifications drilling rod.
The technical scheme that its technical problem that solves the utility model adopts is: scrape mud device for two groups about being provided with in the open type staving.The open type staving forms with bucket sheet hinge clamping ring circle, and bucket is outer to have two handgrips to be used for opening or to close the open type staving.The blade holder outer end of scraping mud device is connected with open type staving hinge, upwards starts by large diameter tool joint the time, and blade holder top has spring to push down; The blade holder inner chamber is installed cleaning shoe, and its front end is spacing with screw.When drilling rod lifts by crane, open the open type staving, scrape and close after mud device is embraced drilling rod, under spring action, scrape the cleaning shoe of mud device up and down and be close to drilling rod all the time, cleaning shoe is a waveform configuration, the function that has elasticity, launches and set upright, add that drilling rod scrapes the deadweight of mud device, just can strike off on drilling rod and the same drilling rod diameter effectively automatically greater than the mud on the joint of drilling rod.When drillng operation is finished the lifting drilling rod,, scrape and just can take out after the mud device is thrown off drilling rod as long as catch two handgrips that the open type staving is drawn back.Can change after the cleaning shoe wearing and tearing, to the different size drilling rod, as long as the cleaning shoe of the corresponding specification of adapted, accomplish that one scrapes the drilling mud practice of scraping that the mud device adapts to the plurality of specifications drilling rod, the open type staving is opened, screw out the screw of front end on the blade holder, just can take out and install cleaning shoe, just can scrape drilling mud practice after screwing screw.
The beneficial effects of the utility model are: scrape mud device for two groups about being provided with in the open type staving, can strike off on drilling rod and the same drilling rod diameter effectively automatically greater than the mud on the joint of drilling rod, and can change the cleaning shoe of different size easily, adapt to the drilling mud practice that strikes off of plurality of specifications drilling rod.The utility model drilling rod is scraped mud device features simple structure, and is safe and reliable, alleviates oil worker's labour intensity.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a broken section front view of the present utility model.
Fig. 2 is a vertical view of the present utility model.
1. springs among the figure, 2. hinge, 3. blade holder, 4. cleaning shoe, 5. handgrip, 6. screw, 7. hinge, 8. open type staving.
The specific embodiment
The open type staving (8) that drilling rod is scraped the mud device forms through hinge (7) clamping ring circle with the bucket sheet, and the outer handgrip (5) of bucket can open or close open type staving (8), is used for throwing off or embracing drilling rod.Scrape mud device for two groups about being provided with in the open type staving (8), blade holder (3) outer end of scraping mud device is connected with hinge (2) with open type staving (8), by large diameter tool joint the time, upwards starts, and blade holder (3) top has spring (1) to push down; The inner chamber of blade holder (3) is installed cleaning shoe (4), and its front end is spacing with screw (6).Under the effect of spring (1), cleaning shoe (4) is close to drilling rod all the time, and cleaning shoe (4) is a waveform configuration, the function that has elasticity, opens and set upright, add that drilling rod scrapes the deadweight of mud device, just can strike off on drilling rod and the same drilling rod diameter effectively automatically greater than the mud on the joint of drilling rod.As long as screw out or screw the screw (6) on the blade holder (3), just can change the cleaning shoe (4) of different size easily, adapt to the drilling mud practice that strikes off of plurality of specifications drilling rod.
Claims (2)
1. a drilling rod is scraped the mud device, it is characterized in that: scrape mud device for two groups about being provided with in the open type staving, the blade holder outer end of scraping mud device is connected with open type staving hinge, and top has spring to push down; The inner chamber of blade holder is installed cleaning shoe, and its front end is spacing with screw.
2. drilling rod according to claim 1 is scraped the mud device, it is characterized in that cleaning shoe is a waveform configuration.
