Abstract
Disclosed is a compensation rope anti-broken safeguard, which is characterized in that: it is equipped parallel beside a compensation device for tension cable rope and can change following the change of compensation length of the compensation device, and it can substitute the compensation device to pull the cable rope when the compensation rope is broken. The safeguard comprises a safety rope, an element inducting acceleration of the safety rope, and a latching element; the element inducting acceleration of the safety rope contains a reel, a shaft and at least one ratcher fixed on the end position of the shaft, the shaft can be actively through the elliptical holes in the two side boards, and on the ratcher at the outside of the side board is equipped with a click, the ratcher and which are comprised the locking element.
Description
Technical field
The present invention relates to contact system tension compensating mechanism in the contact nets in electrified railways system, relate to break proof safety device of compensating rope in the tension compensating mechanism particularly, belong to the electrifing railway supply technical field.
Background technology
The tension compensating of contact system is compensated rope or is strained the lead realization by assembly pulley by the compensation rope by the compensator winding in the contact nets in electrified railways system, thereby the compensation rope is a vital force-summing element in the system.Because compensation rope is bearing very big tension force working environment very severe simultaneously, so even a phenomenon that disconnected strand of broken string takes place because of tired or wearing and tearing is always generation.And compensation rope is in five, six meters aerial, both has been difficult for checking the no reserve of fork that in time change as can not in time finding defective, in case broken string takes place, the contact system that has high-tension current will lose tension force, will cause the accident of abnormal condition and be difficult to recovery in the short time.The present invention is provided with break proof safety device of compensating rope at contact system terminal tension compensating place, in case for making compensation rope broken string, contact system can not lose tension force and repair easily, guarantees the safety of railways train operation.When compensation rope normal operation, the safety rope of break proof safety device of compensating rope stretches out or indentation with the action of compensator, basically neither export tension force and also do not consume tension force, break proof safety device of compensating rope substitutes compensator tension lead immediately in case the compensation rope breaks, and reaches contact system and does not lose the purpose of safety that tension force guarantees railways train operation.
Summary of the invention
Break proof safety device of compensating rope is made up of institutes such as reel, axle, wind spring, corrosion-resistant steel safety rope, mainboard, side plate and line sense locking components, and the effect commercial weight is Tension Difference and principle of inertia.The parts of induction safety rope acceleration/accel are by reel, axle and two ratchet formations that are fixedly mounted on shaft end, axle is through in the oval axis hole of biside plate movably, oval axis hole top, the biside plate outside is equipped with three tooth papillae pawls, it and ratchet are formed locking component, just often, axle and ratchet are installed in the biside plate and act on the cover of two on the axle to be decided on the primary importance of tension spring pressure holding in axis hole, ratchet does not contact with ratchet on this position, and axle can rotate in this position, when when broken string compensation rope reel and axle sense the press force that safety rope certain acceleration and pull power are decided tension spring, axle primary importance from axis hole moves to the second place, ratchet and ratchet close on this position, the rotation of axle is lockable, and the safety rope position that is connected on the lead is fixed, thereby lead still is tightened up.
Description of drawings
For structure of the present invention is better understood, below be described in detail by accompanying drawing.
Fig. 1: scheme of installation of the present invention;
Fig. 2: the cutaway drawing of a kind of embodiment of the present invention.
Fig. 1 adds the selection embodiment that the assembly pulley tension compensating mechanism is installed side by side for the present invention in the contact nets in electrified railways system with the bob stone roller, among the figure, the bob stone roller was ganged up assembly pulley and is made lead keep certain sag for the wire compensation rated tension, when lead elongates or shortens along with variation of temperature, stretch height along with the rotation of assembly pulley or reduce the bob stone roller by the compensation rope, keeping the sag of lead still for the wire compensation rated tension.In case lead is thrown off fully with the bob stone roller but the compensation rope breaks, and causes the accident thereby lead promptly loses the power of pulling and supporting fully.Effect of the present invention is exactly to restrict just often when compensation, safety rope shortens (elongation) along with the elongation (shortening) of lead, and do not apply tension force or consume the tension force that weighs down the stone roller string basically to lead, and as when broken string compensation rope tension sheave A immediately, thereby the unlikely tension force that pulls and supports that loses of lead can not caused the accident, repair easily simultaneously.
Fig. 2 is a kind of structural representation of the present invention: mainboard (1), side plate (2), axle (3), ratchet (4), ratchet (5), wind spring (6), reel (7), safety rope (8), decide tension spring (9), briquetting (10), chock (11), shell (12), bolt (13).Safety rope (8) is fixed and is wrapped on the reel (7) by chock (11), and reel (7) is fixed on the axle (3) by chock (11) simultaneously; Be fixed on wind spring (6) on axle (3) and the mainboard (1) the winding power of safety rope is provided; Axle (3) is through in the oval axis hole (B) of two blocks of side plates (2), ratchet (4) is equipped with at the two ends of axle (3), and be installed in and decide tension spring (9) and briquetting (10) pressure holding on the bottom primary importance of oval axis hole (B) in the biside plate (2), ratchet this moment (4) does not contact with the ratchet (5) that is installed on the biside plate with bolt (13), and can freely rotate in axis hole with axle (3).Because the coiling power (0.1-0.2kN) of wind spring (6) is compared with the specified compensation tension force (10-20kN) of lead and is differed greatly, so can ignore to the influence of compensation tension force.When compensation rope broken string, lead will be suddenly with the outside towing safety rope of its rated tension (8), drive reel (7) and axle (3) upward movement, because the force of inertia that this moment, safety rope (8), reel (7) and spool (3) made progress is much larger than deciding the downward press force (0.15-0.25kN) of tension spring (9) and briquetting (10), axle 3) is pulled to the top second place of oval axis hole (B), ratchet this moment (4) and ratchet (5) engagement and locking, axle (3) can not rotate, and the position of safety rope (8) is fixed.After compensation rope was repaired, the outside tension force of safety rope (8) disappeared, and then axle (3) can be decided tension spring (9) again and pushes back primary importance.
Obviously, under design of the present invention, can also make various remodeling, for example can adopt the form of monolateral ratchet, also can adopt interior ratchet, inertia member is finished locking by mobilizable ratchet, even also can make the induction amount make above-mentioned all kinds of locking component pin reel or the like by drive disk assembly or centre part.Therefore all employings are equal to and replace or the technical scheme of equivalent transformation is all implemented protection domain in claim of the present invention.
Main feature of the present invention is that safety rope can stretch with the action of compensator when the normal operation of compensation rope, And basically do not affect compensation tension force; And when compensation rope broken string, can rely on the engagement of ratchet and pawl to lock immediately End the fixedly position of safety rope, make lead can not lose the power of pulling and supporting, avoid the generation of driving accident, thereby provide A kind of safe reserve.
