Abstract
The invention discloses a multi-link combined mechanism for an iron notch drill of a blast furnace. The multi-link combined mechanism mainly comprises a long connecting rod, a triangular connecting rod, a short connecting rod and a connecting pin roll, wherein a rotary arm is hinged with an iron notch drill fixing base, and the rotary arm is driven by a revolving oil cylinder to rotate; a suspending mechanism is hinged with the rotary arm; the long connecting rod is connected with the tapping machine fixing base and the triangular connecting rod; one end of the short connecting rod is connected with the triangular connecting rod; the other end of the short connecting rod is connected with the suspending mechanism; and the triangular connecting rod is hinged on the rotary arm. According to the combined link mechanism disclosed by the invention, each connecting rod is linked within an extremely small range, so that the suspending mechanism and a travelling rack rotate within a large angle; meanwhile, the angle is changed in a segmented manner, so that the space for turning the travelling rack is saved; and the multi-link combined mechanism can be conveniently applied to a narrow front furnace space of the blast furnace without occupying much of the front furnace space. An effective included angle between a counter-force arm and a force arm of each hinged point is increased through the transitional motion of the triangular connecting rod, the stress distribution of a component is optimized, the stress to each hinged point and the connecting rod is reduced, and the failure probability that the connecting rods, a hinge base and the like are broken or bent is reduced.
Description
Technical field
The present invention relates to a kind of many double cams for iron-smelting blast furnace stokehold iron perforater.
Background technology
At present for the control of iron-smelting blast furnace stokehold iron perforater hanging mechanism and walked frame (hanging mechanism and walked frame link together) track be generally adopt the control mode of monotroded bar or directly and pivoted arm fix the mode of (track designs in advance), such design connecting rod is long, stressed larger, thereby easily break or hit the curved inefficacy that causes, simultaneously less to the adjustment amount of iron perforater posture, space, the required stokehold of frame is larger, blast furnace for stokehold limited space has limitation, is not well positioned to meet such blast furnace user's service requirements and need of production.
Summary of the invention
The object of the invention is to provide a kind of combined mechanism of many connecting rods, provide large adjustment angle by the aggregate motion in the finite space between connecting rod to hanging mechanism and travel mechanism, increase the effective angle between each pin joint counter-force and the arm of force simultaneously, guaranteeing under the prerequisite of torque, to reduce the stressed of each pin joint.
Structure of the present invention is achieved in that the many double cams of a kind of blast furnace open hole machine, on three end points of triangular coupling rod, be respectively equipped with pin joint B, pin joint C and pin joint D, long connecting rod one end is connected with triangular coupling rod by pin joint B, and triangular coupling rod is connected with short connecting rod by pin joint C.
The long connecting rod the other end by pin joint A with drive iron iron perforater permanent seat and be fixedly connected with.
Triangular coupling rod is fixedly connected with iron perforater pivoted arm by pin joint D.
Short connecting rod is connected with hanging mechanism by pin joint E.
It is hinged that described pin joint B, pin joint C, pin joint D, pin joint A and pin joint E is bearing pin.
The combined mechanism of many connecting rods provided by the invention, promote the rotations such as whole pivoted arm and hanging mechanism by the angling cylinder being connected between iron perforater pivoted arm and permanent seat, by this interlock of the each connecting rod of jointed connecting rod mechanism among a small circle, drive hanging mechanism and walked frame to rotate larger angle, rapid adjustment posture is aimed at iron mouth, reduce the space that walked frame turns over, can conveniently be applied to narrow and small State of Blast Furnace front space, work accommodation scope is wide, stokehold space hold is few, can be good at meeting service requirements.Meanwhile, by the transient motion of triangular coupling rod, increase the effective angle between each pin joint counter-force and the arm of force, optimized the distribution of force of structural part, reduced the stressed of each pin joint and connecting rod, reduced that connecting rod, hinged seat are broken or bending probability of failure.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the invention will be further described.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the running trajectory diagram of pin joint, wherein, b, c, e, f represents respectively the movement locus of pin joint B, pin joint C, pin joint E and pin joint F.
Embodiment
As shown in Figure 1, the many double cams of a kind of blast furnace open hole machine, on three end points of triangular coupling rod 2, be respectively equipped with pin joint B5, pin joint C 6 and pin joint D7, long connecting rod 1 one end is connected with triangular coupling rod 2 by pin joint B5, and triangular coupling rod 2 is connected with short connecting rod 3 by pin joint C 6.Long connecting rod 1 the other end by pin joint A8 with drive iron iron perforater permanent seat 9 and be fixedly connected with.Triangular coupling rod 2 is fixedly connected with iron perforater pivoted arm 10 by pin joint D7.Short connecting rod 3 is connected with hanging mechanism 11 by pin joint E4.It is hinged that described pin joint B5, pin joint C6, pin joint D7, pin joint A8 and pin joint E4 is bearing pin.
Principle of work of the present invention is as follows: drive iron perforater pivoted arm 10 to rotate by angling cylinder 12, pivoted arm 10 drives the hanging mechanism 11 being attached thereto and the triangular coupling rod 2 being connected thereon, long connecting rod 1 is hinged between iron perforater permanent seat 9 and triangular coupling rod 2, the motion of triangular coupling rod 2 is subject to the restriction of long connecting rod 1, triangular coupling rod 2 rotates counterclockwise with respect to pin joint D7, thereby drive short connecting rod 3 to move by pin joint C6, this motion and pivoted arm 10 drive the motion synthesis of hanging mechanism 11 to form the compound motion of hanging mechanism 11, this compound motion has been determined the movement locus of walked frame, the F locus of points on hanging mechanism can image the movement locus of expressing walked frame, pin joint B, C, the track of E has reflected the motion of each connecting rod.In the process of rotating relative to pivoted arm inverse clock at triangular coupling rod 2, the angle of hanging mechanism front end and pivoted arm first becomes more greatly, this angle maximum in the time that triangular coupling rod 2 moves to pin joint C, D, E conllinear, along with reducing that this angle of rotation of pivoted arm accelerates again, in the time that the motion of triangular coupling rod 2 exceedes the stagnation point of pin joint C, B, E conllinear, the angle of hanging mechanism front end and pivoted arm reducing sharply, travel mechanism arrived the perpendicular of iron mouth medullary ray rapidly, drilling rod is aimed at iron mouth, and in accompanying drawing 2, the curvature of the F locus of points has well showed this variation.In the rotation process of pivoted arm, triangular coupling rod 2, long connecting rod 1, the motion of short connecting rod 3 in very low range, realized hanging mechanism and walked frame compared with the rotation of wide-angle, and this goniometry subsection changes simultaneously, has saved fully the space that walked frame turns over; By the transient motion of triangular coupling rod 2, increase the effective angle between each pin joint counter-force and the arm of force, optimized the distribution of force of structural part, therefore in the situation that torque is certain, reduce the stressed of each pin joint and connecting rod, reduced that connecting rod, hinged seat are broken or bending probability of failure.
