Abstract
The utility model discloses the swing mechanism of a kind of tunnel descaling machine working arm, it mainly includes underframe, rotating base, hydraulic pressure worm screw, worm gear and working arm, described rotating base entirety is in peviform, hydraulic pressure worm screw is movably arranged on the sidewall of rotating base, this rotating base is fixedly mounted on underframe, described worm gear is movably arranged in rotating base, and this worm gear is connected with hydraulic pressure worm-drive, described working arm is arranged on worm gear, the utility model advantage is: under the rotation control action of hydraulic pressure worm screw, rotate adjusting range controllable precise, and stability of rotation, produce without greater impact power during rotation, rotation limit, limit can be realized and carry out prune job, effectively improve the operating efficiency of prune job.
Description
Technical field
The utility model relates to the technical field of mine machinery, more particularly relates to the technical field of tunnel, mine cleaning machinery.
Background technology
In the recovery process in mine; when hole, ore deposit is excavated, after explosion, its roof and sidewall often there will be loosening stone; these stones are as cleared up not in time; just have the danger split away off at any time; the stone split away off is easy to injure staff by a crashing object, thus brings many potential safety hazards to production.At present, the employing tunnel descaling machine that people have is cleared up the stone that these may split away off at any time, but the weak point that existing tunnel descaling machine in use exists is, tunnel descaling machine is in operation process, working arm can adjust angle often along with the change of cleaning point, the adjustment of this angle is at present the mode rotating base relying on paired hydraulic cylinder to adopt push-and-pull, reach the object that adjustment is positioned at working arm angle on base, when this adjustment mode is rotated on the one hand, the angle position of adjustment can not accurately be held, and adjusting play is large; During adjustment, impact force is comparatively large on the other hand, is positioned at working arm cleaning hammer shaking amplitude foremost comparatively large, is unfavorable for operation, also has influence on operating efficiency simultaneously.
Utility model content
The purpose of this utility model is exactly provide a kind of rotation adjusting range controllable precise to solve above-mentioned deficiency, and stability of rotation, does not affect prune job during rotation, effectively can improve the swing mechanism of the tunnel descaling machine working arm of prune job efficiency.
The technical solution that the utility model adopts to solve the problems of the technologies described above is as follows:
The swing mechanism of tunnel descaling machine working arm, it mainly includes underframe, rotating base, hydraulic pressure worm screw, worm gear and working arm, described rotating base entirety is in peviform, hydraulic pressure worm screw is movably arranged on the sidewall of rotating base, this rotating base is fixedly mounted on underframe, described worm gear is movably arranged in rotating base, and this worm gear is connected with hydraulic pressure worm-drive, and described working arm is arranged on worm gear.
On described worm gear with hydraulic pressure worm-drive connecting portion in the form of a ring.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: under the rotation control action of hydraulic pressure worm screw, rotate adjusting range controllable precise, and stability of rotation, produce without greater impact power during rotation, rotation limit, limit can be realized and carry out prune job, effectively improve the operating efficiency of prune job.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, the swing mechanism of tunnel descaling machine working arm, it mainly includes underframe 1, rotating base 2, hydraulic pressure worm screw 3, worm gear 4 and working arm 5, described rotating base 2 entirety is in peviform, hydraulic pressure worm screw 3 is movably arranged on the sidewall of rotating base 2, this rotating base 2 is fixedly mounted on underframe 1, described worm gear 4 is movably arranged in rotating base 2, and this worm gear 4 is in transmission connection with hydraulic pressure worm screw 3, worm gear 4 is driven to rotate in rotating base 1 by hydraulic pressure worm screw 3, the position that wherein worm gear 4 is in transmission connection with hydraulic pressure worm screw 3 makes and is advisable in the form of a ring, described working arm 5 is arranged on worm gear 4, when worm gear 4 rotates, the working arm 5 be positioned on worm gear 4 also just can swing thereupon.Above-mentioned hydraulic pressure worm screw 3 is prior art, commercially directly can buy and obtain, its structure this without the need to describe in detail.
