Abstract
A stir head for steel stranded wire roof bolt is provided, which is infused into shape with one time. Head of the utility model is composed of two planes and two special arc surfaces; three cuspidal points at the upper part form two pitch arcs; lower part of the stir head has a cone top circle and an inner hole which has two parallel planes matching with that of the roof bolt. The procedure of the stir head is as following: the three cuspidal points on the head lacerate the plastic films firstly, and then stir the resin mortar and the firming agent in between the two layers of the plastic films through the two pitch arcs, the two special arc surfaces on the head control the stiring time, thus ensuring a best stiring effect.
Description
Technical field
The utility model relates to a kind ofly in the supporting, be installed on anchor pole or the steel strand under coal mine, is used for the stirring-head of agitating resin fixing agent for anchor poles.
Background technology
At present, known anchor pole or steel strand front end do not have stirring-head, directly use, and resin-bonded mastic and curing compound in the resin anchor anchoring agent are fully mixed, and solidification effect is poor, and the anchored force value is low.
Summary of the invention
Directly stir the uneven phenomenon of anchoring agent in order to overcome existing anchor pole or steel strand, the utility model provides a kind of stirring-head of anchor pole steel strand, and it can improve mixing effect, makes the anchoring agent obtain full and uniform mixing, can increase the anchored force value.
The technical scheme that its technical problem that solves the utility model adopts is: this stirring-head is the part of single injection-molded, head is made up of two planes and two special cambered surfaces, and intersect two skew lines of head, topmost is formed two camber lines by three cusps, the bottom cylindrical is the conical surface, the bottom endoporus has two parallel planes, and two planes in two planes of endoporus and anchor pole cooperate.
The beneficial effects of the utility model are that the anchoring agent that is stirred is mixed.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the front view of the utility model stirring-head.
Among the figure, 1, the flat figure of two on head, 2, three cusps of head, 3, two camber lines of head, 4, two special cambered surfaces of head, 5, two skew lines, 6, the bottom outer conical surface, 7, two parallel facing directly of endoporus, 8, endoporus.
The specific embodiment
This stirring-head is the part of single injection-molded, head is made up of two planes (1) and two special cambered surfaces (4), topmost is formed two camber lines (3) by three cusps (2), the bottom cylindrical is the conical surface (6), bottom endoporus (8) has two parallel planes (7), and two planes in (8) two planes of endoporus (7) and anchor pole cooperate.During use, endoporus (8) is inserted in rock bolt head, two planes of anchor pole cooperate with two parallel planes of stirring-head endoporus (7), play the location clamping action.Rotation with stirring-head advances, three cusps of head (2) scratch anchoring agent plastic film bag, by two camber lines of head (3) stirring action, make and be divided in resin-bonded mastic and the curing compound of plastic film bag in two-layer and obtain full and uniform mixing, mixture will glide along two planes of head (1) and crossing two skew lines (5) of two special cambered surfaces of head (4), slide to bottom outer conical surface (6) under continuing, bottom outer conical surface (6) is up big and down small, has reduced the resistance that glides.Two special cambered surfaces of head (4) can play certain drag effect, make mixing time suitable, are unlikely to too fast, reach best mixing effect.
Claims (1)
1, a kind of stirring-head that is used for the anchor pole steel strand is characterized in that: its head is made up of two planes (1) and two special cambered surfaces (4), and intersects two skew lines of head (5), and topmost is formed two camber lines (3) by three cusps (2).
