Abstract
A kind of anchor pole of quick bending relates to a kind of supporting product that the colliery underworkings uses that is used for specifically, comprises the body of rod (1), it is characterized in that: groove milling (2) is set on the body of rod (1).Owing to be provided with groove milling on the body of rod, needed power reduces when making the bending anchor pole, has reduced workman's workload, has reduced working strength of workers, has filled up the blank in this area.
Description
Technical field
The utility model relates to a kind of anchor pole of quick bending, relates to a kind of supporting product that the colliery underworkings uses that is used for specifically.
Background technology
Along with the development of mine bolt support technology, anchor pole increases gradually at the consumption of down-hole.According to mine or underground work requirement, the part anchor pole need change the fastening direction of anchor pole at different work planes.When often the workman carries out Bending Processing in the tunnel exactly bending and when the common anchor pole of bending, need bigger strength to the angle that needs, increased working strength of workers.Therefore, the twisted steel anchor rod that uses at present needs further improvement.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of and can adjust fastening direction and position as required, and can reduce the anchor pole of the quick bending of labor strength.
The technical scheme that its technical problem that solves the utility model adopts is: the anchor pole of this quick bending, comprise the body of rod, and it is characterized in that: on the body of rod, increase groove milling.The body of rod goes out groove milling by Milling Process, makes the body of rod attenuation of groove milling place.
The body of rod is screw-thread steel or fried dough twist steel, and groove milling is single-sided structure or bilateral structure.100 millimeters of the length of groove milling, the degree of depth are the 4-6 millimeter.Groove milling is arranged on the middle part of the body of rod.Or be arranged on an end of the body of rod.
Compared with prior art, the beneficial effect that the anchor pole of quick bending of the present utility model has is: owing to be provided with groove milling on the body of rod, after the anchor pole groove milling processing, meet the safety in production requirement.Do bending and tensile test according to the practical application condition, stretching resistance is not less than 120KN, crooked 90 ° of 30-45 kilograms of exerting oneself during bending.Needed power reduces when making the bending anchor pole, has reduced workman's workload, has reduced working strength of workers, has filled up the blank in this area.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
The specific embodiment
Fig. 1 is a most preferred embodiment of the present utility model, wherein: 1, the body of rod 2, groove milling
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, the body of rod 1 of twisted steel anchor rod goes out groove milling 2 by Milling Process, makes the body of rod 1 attenuation at groove milling 2 places, becomes to be thick plate-like.
Different length (1400 millimeters-2000 millimeters) according to anchor pole carries out Milling Process at 500 millimeters-800 millimeters position double thread steel anchor rods, processes 100 millimeters of the length of groove milling 2,4 millimeters-6 millimeters of the degree of depth of two-sided Milling Process.But also single face Milling Process.After the anchor pole groove milling processing, meet the safety in production requirement.Do bending and tensile test according to the practical application condition, stretching resistance is not less than 120KN, crooked 90 ° of 30-45 kilograms of exerting oneself during bending.Make workman's ratio be easier to crooked anchor pole, reduced labour intensity and workload.And improved the degree of accuracy of bending.Adjust the fastening direction of anchor pole, angle or position for the underground labour, very big benefit is arranged.
