Description
Technical field
The utility model relates to geological prospecting apparatus field, particularly relates to reamer.
Background technology
In prior art, there is following shortcoming in reamer: the reaming bar of reamer is cylindrical structural, the friction of itself and earth rubble is less, not enough to the shred-ability of earth rubble, there is relatively large earth rubble easily stuck in the middle of waistband and cross bar, cause reamer and other parts damages, cause feeding efficiency low; Bonding area between reaming bar and waistband inwall is little, and weld strength is not high; Waistband only plays a supportive role, and without fraising function, reaming efficiency is low; The reaming resistance of reamer is large, and bore edges is comparatively coarse, is unfavorable for the drilling operation in later stage.
Utility model content
The shortcoming that the applicant exists for above-mentioned prior art, carries out studying and improving, and provide a kind of reamer with cylinder fraising formula waistband, it has, and reaming is effective, reaming efficiency is high, the feature of stable connection.
The technical scheme that the utility model adopts is as follows:
A kind of reamer with cylinder fraising formula waistband, comprise belt body, the center of belt body to be connected drilling rod by cross bar, many main reaming bars are fixed with between belt body and drilling rod, the relative drilling rod Central Symmetry of main reaming bar is arranged, drilling rod, main reaming bar and cross bar are hollow-core construction, described belt body comprises upper and lower spaced belt loop, polylith gripper shoe is connected with between two belt loops, the lower end inside cornice of gripper shoe has welding groove, the upper end welding of main reaming bar is fixed in welding groove, and the cross section of main reaming bar is square structure; Be rotatably connected to multiple fraising cylinder arranged about described belt body Central Symmetry between upper and lower belt loop, the outer wall of fraising cylinder is evenly equipped with alloy block;
The outer wall of described main reaming bar is evenly equipped with alloy block; Cross bar is fixed in gripper shoe, is symmetrically connected with auxiliary reaming bar between the outer wall of cross bar and the outer wall of drilling rod, and auxiliary reaming bar is hollow structure, and its outer wall is evenly equipped with alloy block.
Further improvement as technique scheme:
Described welding groove is square groove structure.
With those widened sections on described belt loop, rotate between upper and lower those widened sections and described fraising cylinder is installed.
The cross section of described auxiliary reaming bar is square.
The beneficial effects of the utility model are as follows:
The utility model adopts main reaming bar and the auxiliary reaming bar of square structure, realizes the upper and lower both sides of waistband and reams simultaneously, improve the frictional force to saprolite ore, and raising blends, reaming effect and efficiency; Adopt fraising roller frame, reduce reaming resistance, improve reaming efficiency and reaming quality; Waistband arranges welding groove structure, is convenient to weld with reaming bar, and improves bonding strength.
Accompanying drawing explanation
Fig. 1 is three-dimensional structure diagram of the present utility model.
Fig. 2 is the three-dimensional structure diagram of waistband of the present utility model.
In figure: 1, belt loop; 11, those widened sections; 2, gripper shoe; 21, groove is welded; 3, alloy block; 4, ream cylinder; 5, drilling rod; 6, cross bar; 7, main reaming bar; 8, auxiliary reaming bar.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
As Fig. 1, shown in Fig. 2, the reamer of the band cylinder fraising formula waistband of the present embodiment, comprise belt body, the center of belt body to be connected drilling rod 5 by cross bar 6, many main reaming bars 7 are fixed with between belt body and drilling rod 5, main reaming bar 7 relatively drilling rod 5 Central Symmetry is arranged, drilling rod 5, main reaming bar 7 and cross bar 6 are hollow-core construction, belt body comprises upper and lower spaced belt loop 1, polylith gripper shoe 2 is connected with between two belt loops 1, the lower end inside cornice of gripper shoe 2 has welding groove 21, the upper end welding of main reaming bar 7 is fixed in welding groove 21, the cross section of main reaming bar 7 is square structure, be rotatably connected to multiple fraising cylinder 4 arranged about shown belt body Central Symmetry between upper and lower belt loop 1, the outer wall of fraising cylinder 4 is evenly equipped with alloy block 3.When reamer rotates reaming, belt body is rotated thereupon, and in rotation process, fraising cylinder 4 also self rotates around the center rotating of belt body, realizes fraising, and its fraising resistance is little, and bore edges planeness is high.
The outer wall of main reaming bar 7 is evenly equipped with alloy block 3; Cross bar 6 is fixed in gripper shoe 2, is symmetrically connected with auxiliary reaming bar 8 between the outer wall of cross bar 6 and the outer wall of drilling rod 5, and auxiliary reaming bar 8 is hollow structure, and its cross section is square, and its outer wall is evenly equipped with alloy block 3.Auxiliary reaming bar 8 assists main reaming bar 7 to ream, and improves fraising efficiency.
Welding groove 21 is square groove structure, and the groove bottom of welding groove 21 is plane, is beneficial to the bonding area increased with main reaming bar 7, improves weld strength.
With those widened sections 11 on belt loop 1, rotate between upper and lower those widened sections 11 and fraising cylinder 4 is installed.
The utility model adopts main reaming bar and the auxiliary reaming bar of square structure, realizes the upper and lower both sides of waistband and reams simultaneously, improve the frictional force to saprolite ore, and raising blends, reaming effect and efficiency; Adopt fraising roller frame, reduce reaming resistance, improve reaming efficiency and reaming quality; Waistband arranges welding groove structure, is convenient to weld with reaming bar, and improves bonding strength.
More than describing is to explanation of the present utility model, and be not the restriction to utility model, the utility model limited range is see claim, and when without prejudice to spirit of the present utility model, the utility model can do any type of amendment.
