Abstract
The utility model belongs to the technical field of mining anchor rods and provides a deviation preventing anchor rod which can avoid large deviation between the center of the anchor rod and the center of a drill hole in the anchoring process. The deviation preventing anchor rod comprises an anchor rod body and locating rings, and the locating rings are sleeved on the anchor rod body. The number of the locating rings is at least two, and the positions of the two locating rings are fixed. The two locating rings are respectively sleeved on a free section and an anchoring section of the anchor rod body. The deviation preventing anchor rod is mainly used for coal mine supporting.
Description
Technical field
A kind of anti-bias anchor pole of the utility model belongs to the mine anchor rod technical field.
Background technology
Along with the constantly bringing forth new ideas and develop of Coal Mining Technology, the coal mine support technology also develops into steel lining by initial wooden support, and steel lining is progressively substituted by anchor net beam rope spray combined supporting at present, and develops into active support by initial passive protecting.Because bolt support technology is constantly perfect; rely on its significant advantage in colliery tunnel support, to use more and more extensive; but the bore size of installing anchor pole is generally than the large 4～6mm of diameter of anchor rod body; therefore there are relatively large deviation in anchor pole center and drill center; in anchor rod anchored process, often can cause the Anchor Agent filling inhomogeneous, reduced the anchored force of anchor pole; have a strong impact on the roadway support quality, come major hidden danger for the colliery safety belt.
The utility model content
The utility model overcomes the deficiency that prior art exists, and technical problem to be solved provides and a kind ofly can prevent that in anchor rod anchored process the anchor pole of relatively large deviation from appearring in anchor pole center and drill center.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of anti-bias anchor pole, and comprise anchor rod body and be sleeved on locating ring on the anchor rod body, described locating ring is at least two and position and fixes.
Described two locating rings are set in free segment and the anchoring section of anchor rod body.
The utility model is compared with existing technology has following beneficial effect.
One, passes through at least two locating rings of anchor rod body setting, so that when anchor pole carries out anchoring, it is amesiality in boring that locating ring can limit anchor pole, and locating ring also can limit Anchor Agent along anchor rod body and boring to the inhomogeneous diffusion of whole boring, guaranteed anchor rod anchored effect and quality.
Two, the utility model is only made simple change to existing anchor rod body, reasonable in design, simple in structure, low production cost by locating ring is set at the body of rod.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, 1 is anchor rod body, and 2 is locating ring.
The specific embodiment
As shown in Figure 1, a kind of anti-bias anchor pole comprises anchor rod body 1 and is sleeved on locating ring 2 on the anchor rod body 1, and described locating ring 2 is at least two and position and fixes.
Described two locating rings 2 are set in free segment and the anchoring section of anchor rod body 1.
The installation of locating ring 2 is finished by press mounting die in the utility model: select press mounting die at the anchor rod body 1 of different size first, then press mounting die is fitted in locating ring 2 on the anchor rod body 1.
In anchor rod anchored process, first Anchor Agent is put into boring, then rapidly the utility model is inserted boring and get final product.
Claims (2)
1. anti-bias anchor pole is characterized in that: comprise anchor rod body (1) and be sleeved on locating ring (2) on the anchor rod body (1), described locating ring (2) is at least two and position and fixes.
2. a kind of anti-bias anchor pole according to claim 1, it is characterized in that: described two locating rings (2) are set in free segment and the anchoring section of anchor rod body (1).
