Abstract
The utility model belongs to the technical field of roller drill equipment, and particularly relates to a rod stabilizer for a roller drill. The rod stabilizer for the roller drill comprises a rod body and a rib plate fixed on the rod body. The rod stabilizer for the roller drill is characterized in that an annular ditch groove is arranged in the rod body, the bottom surface of the annular ditch groove is in circular arc shape, the annular ditch groove is located at the position of the upper end face of the rib plate, a group of radial separating boards are evenly arranged in the annular ditch groove, and the annular ditch groove is separated into a group of grooves which are independent from each other through the radial separating boards. The number of the group of the radial separating boards is 3 to 6. According to the application of the rod stabilizer for the roller drill, a phenomenon that a rod stabilizer is scrapped due to the fact that the diameter of the upper end face of the rib plate of the rod stabilizer is abraded can be completely eradicated. The service life of the rod stabilizer is integrally prolonged, production efficiency can be improved, maintenance times of equipment are reduced, and production cost is reduced.
Description
Technical field
The utility model belongs to the technical field of rotary drill equipment, particularly a kind of rotary drill virtual calibrator for instrument transformer.
Background technology
The virtual calibrator for instrument transformer that uses both at home and abroad at present divides vane type virtual calibrator for instrument transformer, drum-type virtual calibrator for instrument transformer and damper formula virtual calibrator for instrument transformer by structure.And the rotary drill virtual calibrator for instrument transformer majority that use in domestic mine belongs to the vane type virtual calibrator for instrument transformer, its structure is comprised of the body of rod, gusset, alloy column, simple in structure, be easy to make, cost is lower, large with the hole wall contact area, good stability, the virtual calibrator for instrument transformer vibrations that can withstand shocks in perforation procedure are reversed and the operation of the complex load such as axial compression.And the ore deposit of discharging between hole wall and the virtual calibrator for instrument transformer, rock produce the sandblast corrasion to the virtual calibrator for instrument transformer surface, so exist its shortcoming to be: the ore deposit rock dust flows through in virtual calibrator for instrument transformer and the gusset end face process, because it is large that the deslagging volume becomes, the flow-passing surface of sudden enlargement slows down because of blast bust flow velocity, the flow direction changes and produces the phenomenons such as collision, whirlpool under rotating effect, be easy to cause the local heavy wear of the body of rod, must tie up timely replacing in case the local heavy wear of the body of rod occurs, otherwise easily cause virtual calibrator for instrument transformer to rupture at fray.
Summary of the invention
The utility model provides a kind of rotary drill virtual calibrator for instrument transformer, solves the wearing and tearing of virtual calibrator for instrument transformer local diameter and comparatively fast causes virtual calibrator for instrument transformer to be scrapped in advance, affect the problem of production operation efficiency and cost of idleness, is beneficial to prolong virtual calibrator for instrument transformer application life, saves cost, the raising operating efficiency.
The purpose of this utility model realizes by following technical proposals:
Rotary drill virtual calibrator for instrument transformer of the present utility model, comprise the body of rod and the gusset that is fixed on this body of rod, it is characterized in that being provided with the ring-shaped groove that basal surface is circular arc at the described body of rod, this ring-shaped groove is positioned at the upper end surface of described gusset, in described ring-shaped groove, evenly be provided with one group of radially dividing plate, this radially dividing plate described ring-shaped groove is divided into separately independently one group of groove.
Described one group radially the quantity of dividing plate be 3-6.
Advantage of the present utility model:
The phenomenon of scrapping virtual calibrator for instrument transformer because of wearing and tearing virtual calibrator for instrument transformer gusset upper surface diameter has been stopped in application of the present utility model.Integral body has prolonged the application life of virtual calibrator for instrument transformer, and can enhance productivity, and reduces plant maintenance, lowers cost of production.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A sectional view of the utility model Fig. 1.
The specific embodiment
Below in conjunction with the description of drawings specific embodiment of the present utility model.
As shown in Figure 1, rotary drill virtual calibrator for instrument transformer of the present utility model, comprise the body of rod 1 and the gusset 2 that is fixed on this body of rod, it is characterized in that being provided with the ring-shaped groove that basal surface is circular arc at the described body of rod 1, this ring-shaped groove is positioned at the upper end surface of described gusset, in described ring-shaped groove, evenly be provided with one group of radially dividing plate 3, this radially dividing plate 3 described ring-shaped groove is divided into separately independently one group of groove.Gusset 2 upper end surfaces of virtual calibrator for instrument transformer are heavy wear place in the work, by uniform welding 3-6 radially dividing plate 3, form independently one group of groove, this groove namely becomes part and deposits the isolation channel that slag enters, slag muck is isolated the groove partition so one by one, no longer swirl or relative motion, thereby avoid wearing and tearing the body of rod herein.
Described one group radially the quantity of dividing plate be 3-6.This radially the quantity of dividing plate can decide according to the body of rod 1 outside dimension size.
Claims (2)
1. rotary drill virtual calibrator for instrument transformer, comprise the body of rod and the gusset that is fixed on this body of rod, it is characterized in that being provided with the ring-shaped groove that basal surface is circular arc at the described body of rod, this ring-shaped groove is positioned at the upper end surface of described gusset, in described ring-shaped groove, evenly be provided with one group of radially dividing plate, this radially dividing plate described ring-shaped groove is divided into separately independently one group of groove.
2. rotary drill virtual calibrator for instrument transformer according to claim 1, it is characterized in that described one group radially the quantity of dividing plate be 3-6.
