Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
As Figure 1-3, for an embodiment of a kind of scraper of this utility model, including:
Main body sleeve 1, mud-scraping ring 2.The outer ring at main body sleeve 1 two ends is provided with mud-scraping ring 2 the most uniformly, and mud-scraping ring 2 is for striking off the foreign material mud within drilling rod.It is provided with installing hole 3 in the middle part of main body sleeve 1, for being connected (it is internal that drive mechanism stretches into main body sleeve 1, is connected with installing hole 3 from inside) with other drive mechanisms, drives scraper to move inside drilling rod.The plane that mud-scraping ring 2 is formed is vertical with the axis of main body sleeve 1, scrapes mud efficiency height, and makes simpler, and location is convenient.Preferably, drive mechanism can also drive scraper to rotate, and strengthens the effect scraping mud.
Main body sleeve 1 two ends and position in the middle part of main body sleeve 1, mud-scraping ring 2 junction are respectively equipped with back-up ring 4.Match with the external diameter of drive mechanism, for the junction of scraper with drive mechanism is played a protective role so that equipment serviceability is more stable.
Main body sleeve 1 two ends are provided with mud-scraping ring installing hole, are used for installing mud-scraping ring 2.Mud-scraping ring 2 is respectively arranged at two ends with a circle at main body sleeve 1, can not only ensure to scrape mud effect, and reduce scraper weight, improves serviceability, maintenance convenient for cleaning.
Preferably, mud-scraping ring 2 is steel strand wires material, has certain toughness, it is possible to adapt to the change of the inwall of article to be cleaned, it may have corresponding working strength, draws materials conveniently, and makes simple.Steel strand wires coherent and roundabout through mud-scraping ring installing hole, formed in main body sleeve 1 end and be interspersed, the multi-turn circulus being made up of some ringlets, such mud-scraping ring 2 simple in construction, easy to make, it is possible to be greatly shortened fabrication cycle, and easy to maintenance, reduce use cost.Being positioned at the multi-turn circulus at main body sleeve 1 two ends along the orthographic projection of main body sleeve 1 axis is the radially staggered distribution along main body sleeve 1.After the mud-scraping ring 2 of front end scrapes mud, the mud-scraping ring 2 of rear end strike off the position that front end does not scrape, scrape mud effect more preferable.
Preferably, installing hole 3 is uniformly distributed around main body sleeve 1 axis, and each installing hole 3 is internal is equipped with installation connecting element 5.
Further, installing hole 3 is provided with five.The stress produced during scraping mud can be dispersed in, prevent stress concentrations, cause scraper and the damage fracture of drive mechanism junction, improve service life of equipment.
Further, installation connecting element 5 connects seat for female thread.This installation connecting element 5 is welded on main body sleeve 1, penetrating mounting holes 3, and connecting of drive mechanism has corresponding hole on end, can be firmly installed on drive mechanism by scraper by threaded connectors such as bolts, and easy to loading and unloading, work efficiency is higher.
Preferably, mud-scraping ring 2 includes the front mud-scraping ring 6 being located at main body sleeve 1 front end and is located at the rear mud-scraping ring 7 of main body sleeve 1 rear end, the number of turns of the multi-turn circulus of front mud-scraping ring 6 is less than the number of turns of the multi-turn circulus of rear mud-scraping ring 7, the more crypto set that i.e. rear mud-scraping ring 7 is distributed than the multi-turn circulus of front mud-scraping ring 6.The inwall that front mud-scraping ring 6 treats cleaning member slightly cleans, and subsequently, rear mud-scraping ring 7 carries out finer cleaning to the inwall after thick cleaning, improves the effect of cleaning.
Main body sleeve 1 and mud-scraping ring 2 outer surface are equipped with corrosion-resistant finishes, are possible to prevent the external environment corrosion to scraper, the service life of extension device.
After using said structure, scraper simple in construction, easy to use and stable performance, it is possible to effectively cleaning foreign material within drilling rod, improves the work efficiency of equipment, reduces the mud corrosion to equipment, improve the service life of equipment.
