Abstract
The utility model discloses a mining stock bar straightener. This mining stock bar straightener's structure does: the afterbody of frame (1) is provided with protection casing (2), is provided with the dolly that moves about (3) on frame (1), and frame (1) both sides are provided with two -way pneumatic cylinder (4), is provided with tensile furniture a (5) and tensile furniture b (5') on the dolly that moves about (3), and the head of frame (1) is provided with spacing protection device (6). The utility model discloses convenient operation operates steadily, and the security is good, and what realization that can be quick was crooked flare -outs, strikes straight speed than the manual work and improves more than 5 times.
Description
Technical field
The utility model belongs to support apparatus in coal mine recovery technique field, a kind of mine anchor rod straightening machine of special design.
Background technology
Along with coal mine roadway suspension roof support application more and more general, the bolt deformation reclaimed in stope drift active workings is serious, if do not repair, use will cause the waste of very large support material, but the anchor pole flexibility after reclaiming is larger, general employing manually uses sledgehammer to carry out beaing the repair of straightening, cause remediation efficiency low, multiplexing requirement is not reached by the anchor pole smashed, what is more important adopts manually carries out the speed of repairing and quality is unable to catch up with the instructions for use of coal mining enterprise to repair materials, therefore, multiplexing in order to better improve anchor recovering, economize expense and reduce expend effect, save each root anchor pole and all can bring benefit to bargh, when requiring for reparation anchor pole, not only need to increase work efficiency, when needing distortion and don't the reduction performance controlling anchor pole simultaneously, a kind of mine anchor rod straightener needed.
Summary of the invention
For solving the problem; the utility model spy provides a kind of mine anchor rod straightener; it is characterized in that: the afterbody of frame (1) is provided with protective cover (2); frame (1) is provided with travelling dolly (3); frame (1) both sides are provided with two-way hydraulic cylinder (4); travelling dolly (3) is provided with stretching furniture a(5) and stretching furniture b(5 '), the head of frame (1) is provided with limiting and protecting device (6).Frame of the present utility model and protective cover adopt closedown structure design, when accomplishing protective cover not locking, hydraulic system can not start, magnetic valve must not be electric, locking is carried out to two-way hydraulic cylinder liquid feeding pipeline, after ensureing anchor pole clamping, if do not put down protective cover, oil cylinder akinesia, employing two-way hydraulic cylinder is arranged, on cylinder system, use safety valve and two-way hydraulic valve are protected, limiting and protecting device adopts photoelectric sensor to position control, to the overvoltage of oil cylinder and position is protected and relevant function controls, travelling volume the car design is connected with two-way hydraulic cylinder in frame, Main Function drives bending anchor pole to carry out the operation stretched, stretching clamp is arranged on travelling dolly, its effect steps up anchor pole other end stretching clamp to have self-locking action, press from both sides tighter and tighter along with the elongation of horizontal hydraulic cylinder.
The utility model is easy to operate, operates steadily, and what can realize fast bending is stretching, more manually strikes straight speed and improves more than 5 times.Three people repaired 40 anchor poles in one day in the past, and labour intensity is large, and anchor-bar stretch-straightening both saved manpower, accelerates again the speed of repairing anchor pole.Effectively can ensure the quality of anchor pole, overcome the phenomenon of manually striking straight anchor pole linearity.Security is good.Roof-bolter self-locking jig, anchor pole reliable clamping, not easily deviates from.One people one day on average can repair about 220 a man-hour.
