Abstract
The invention provides a rotation turns limit protective device, which is applied in the industry of circular stockyard prehomogenization equipment. The whole device consists of a bracket, a screw rod, a nut, a driven gear, a pointer, a scale and a rotary gear ring, wherein the driven gear is arranged on the rotary gear ring under a piling device of a circular stockyard stacker-reclaimer, is engaged with an open gear to rotate, and drives the nut in a screw pair to axially move; the device drives the driven gear to rotate through the rotation of the piling device, and converts angular displacement of the driven gear into linear displacement of the nut and the pointer through a screw mechanism, and controls the rotation turns and the limit position of the piling device by detecting and limiting the linear displacement; and the bracket is fixed on the piling device to support the device, the screw is driven to rotate through the rotation of the driven gear along with the rotation of the piling device. The device overcomes the limit and protection of the rotation turns of the circular stockyard stacker-reclaimer in a severe environment so as to ensure the safety of fiber slip rings.
Description
Technical field:
The present invention relates to be applied to the pre-homogenization installation of circular stockyard turns round the restriction of the number of turns and protection or other need device to restriction of the revolution number of turns and protection in harsh environment in harsh environment.
Background technology:
Advantages such as at present, the application of circular stockyard stacker-reclaimer enlarges gradually, and its occupation of land is little, reserves are big more and more are subjected to client's favor.Circular stockyard stacker-reclaimer and master control system adopt the mode of radio communication and ferry optics comunication usually, but a lot of user wishes to adopt optical fiber to come transmitting signal, and because fiber optic shunt and coupling are very difficult, so need the revolution number of turns of control optical fiber slip ring.Therefore, develop a kind of number of turns limiting protector that turns round is new problem anxious to be solved always.
Summary of the invention:
The object of the present invention is to provide a kind of circular stockyard stocker turns round the number of turns in harsh environment restriction and protection that solve, guarantee a kind of revolution number of turns limiting protector of the safety of optical fiber slip ring.
The object of the present invention is achieved like this: a kind of revolution number of turns limiting protector, whole device is made up of support, thread rod, nut, driven gear, pointer, scale, gyration gear ring, a driven gear is installed on the gyration gear ring of the windrow device bottom of circular stockyard stacker-reclaimer, by being rotated, and drive moving axially of nut in the screw pair with exposed gear engagement; Device drives the rotation of driven gear by the rotation of windrow device, convert the angular transposition of driven gear the displacement of the lines of nut and pointer to by screw mechanism then, finally by detecting and the rotating cycle and the end position of windrow device are controlled in the restraining line displacement; Support is fixed on this device of windrow device upper support, drives the rotation of driven gear during along with the rotation of windrow device, and then drive the rotation of thread rod; Force nut to move axially because of support has limited freely rotating of thread rod upper nut, thereby drive pen travel; When the windrow device rotates, drive the rotation of driven gear, thereby drive the rotation of thread rod; , and drive pen travel because of thereby support forces nut to move axially by the rotation that pointer has limited the thread rod upper nut; Because of the structure of gear and screw pair known, so can calculate the angular transposition of gear rotation and nut shaft relation to displacement of the lines, and then can calculate the anglec of rotation of windrow device by the axial displacement of nut, just can determine the revolution number of turns of stocker, thereby just can limit the displacement of thread rod upper nut and the revolution number of turns and the end position that the limit limits the windrow device by the position of setting impact switch by the total indicator reading on the scale.
Main points of the present invention are its structure and principle of work.Principle of work is when the windrow device rotates, to drive the rotation of driven gear, thereby drive the rotation of thread rod; , and drive pen travel because of thereby support forces nut to move axially by the rotation that pointer has limited the thread rod upper nut; Because of the structure of gear and screw pair known, so can calculate the angular transposition of gear rotation and nut shaft relation to displacement of the lines, and then can calculate the anglec of rotation of windrow device by the axial displacement of nut, just can determine the revolution number of turns of stocker, thereby just can limit the displacement of thread rod upper nut and the revolution number of turns and the end position that the limit limits the windrow device by the position of setting impact switch by the total indicator reading on the scale.
A kind of revolution number of turns limiting protector compared with prior art; have and solve the circular stockyard stocker turns round the number of turns in harsh environment restriction and protection; guarantee the advantages such as safety of optical fiber slip ring, will be widely used in the pre-homogenization installation industry of circular stockyard.
Description of drawings
The present invention is described in detail below in conjunction with accompanying drawing and example.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is principle of the invention figure.
Fig. 3 is a circular stockyard stacker-reclaimer overall structure scheme drawing.
The specific embodiment:
With reference to accompanying drawing, a kind of revolution number of turns limiting protector, whole device is made up of support 1, thread rod 2, nut 3, driven gear 4, pointer 5, scale 6, gyration gear ring 7, a driven gear 4 is installed on the windrow device bottom of circular stockyard stacker-reclaimer gyration gear ring 7, by being rotated, and drive moving axially of nut 3 in the screw pair with exposed gear engagement; Device drives the rotation of driven gear 4 by the rotation of windrow device, convert the angular transposition of driven gear 4 displacement of the lines of nut 3 and pointer 5 to by screw mechanism then, finally by detecting and the rotating cycle and the end position of windrow device are controlled in the restraining line displacement; Support 1 is fixed on this device of windrow device upper support, drives the rotation of driven gear 4 during along with the rotation of windrow device, and then drive the rotation of thread rod 2; Force nut 3 to move axially because of support 1 has limited freely rotating of thread rod 2 upper nuts 3, move thereby drive pointer 5; When the windrow device rotates, drive the rotation of driven gear 4, thereby drive the rotation of thread rod 2; Because of thereby support 1 forces nut 3 to move axially by the rotation that pointer 5 has limited thread rod 2 upper nuts 3, and drive pointer 5 moves; Because of the structure of gear and screw pair known, so can calculate the angular transposition of gear rotation and nut shaft relation to displacement of the lines, and then can calculate the anglec of rotation of windrow device by the axial displacement of nut, just can determine the revolution number of turns of stocker, thereby just can limit the displacement of thread rod 2 upper nuts 3 and the revolution number of turns and the end position that the limit limits the windrow device by the position of setting impact switch by the total indicator reading on the scale 6.Thereby the rotation that drives driven gear 4 by the revolution of windrow device makes nut 3 produce the novel rotation number of turns limiting protector that moves axially and can move in harsh environment; read and calculate the number of turns by pointer, limit the number of turns and preventive device by impact switch.
