Description
Technical field
The utility model relates to a kind of auxiliary device of back(ing) bar, particularly relates to a kind of back(ing) bar fender guard.
Background technology
Traditional back(ing) bar; do not possess the actv. fender guard; particularly in the light of stage industry; back(ing) bar is widely used in hanging the high stage lamp of value; once the back(ing) bar wire cable rupture is pounded; relevant stage lamp just can fall, and will people's life or property be damaged or damage like this.Good settling mode is not arranged at present as yet.
The utility model content
Based on this, at the problems referred to above, the utility model proposes a kind of back(ing) bar fender guard, behind the back(ing) bar wire cable rupture, can in time stop stage lamp down to fall.
The technical solution of the utility model is: a kind of back(ing) bar fender guard; comprise base plate; the parallel left side board that is oppositely arranged and right side board; pillar stiffener; the ratchet that matches and ratchet; the ratchet anchor shaft; ratchet anchor shaft and steel wire disk; the two ends difference vertical fixing of described pillar stiffener is on left side board and right side board; described ratchet anchor shaft; the two ends of described ratchet anchor shaft rotating shaft respectively are connected on left side board and the right side board; captive joint with described ratchet in the center that described ratchet anchor shaft passes described ratchet; be connected with an end of retracing spring on the described ratchet; the other end of this retracing spring is connected on the left side board; described ratchet anchor shaft passes the centre hole of ratchet successively and the center of steel wire disk is fixed with ratchet and steel wire disk respectively, and described base plate is provided with steel rope and penetrates the hole.
The steel rope that twines on the steel wire disk and the steel rope of back(ing) bar are connected on the stage lamp respectively; when fracture takes place in the steel rope of back(ing) bar; steel rope on stage lamp and the back(ing) bar fender guard links together; just can spur the steel rope of back(ing) bar fender guard this moment; steel rope drives steel wire disk and rotates; because steel wire disk and ratchet all are fixed on the ratchet anchor shaft; therefore steel wire disk drives the rotation of ratchet anchor shaft; the ratchet anchor shaft drives ratchet and rotates; ratchet and ratchet cooperatively interact; when ratchet is followed the ratchet anchor shaft when rotating, ratchet is followed ratchet and is rotated the resistance that is subjected to retracing spring after the very little angle.Making ratchet produce resistance stops ratchet to rotate, this moment, the ratchet anchor shaft stopped operating, steel wire disk is stopped operating, thereby the assurance steel rope is not followed stage lamp and is dropped together, and stage lamp is connected on the steel rope, principle can stop stage lamp to fall downwards thus, thus the equal safety of bondsman's life and property.
In a preferred embodiment, be provided with negative thread in the centre hole of described ratchet, described ratchet anchor shaft is provided with the outside thread that matches with ratchet centre hole negative thread.Purpose is to guarantee that ratchet and ratchet anchor shaft can be for convenience detach.
In a preferred embodiment; this back(ing) bar fender guard also comprises constant force spring and the constant force cheese of being located on the ratchet anchor shaft; this constant force cheese is between described ratchet and described steel wire disk, and an end of described constant force spring connects described constant force cheese, and the other end connects described pillar stiffener.Purpose is that the contraction of constant force spring itself being arranged or draw high provides a pulling force, guarantees the normal folding and unfolding steel rope of steel wire disk by this pulling force when the normal lifting of back(ing) bar fender guard or decline.
In a preferred embodiment, described pillar stiffener level is located at the top of described left side board and right side board.Purpose is effective connection of being convenient to the constant force spring.
In a preferred embodiment, be provided with damping spring between described ratchet and the described constant force cheese, this damping spring is placed on the described ratchet anchor shaft, and the one end connects described ratchet, and the other end connects described constant force cheese.When back(ing) bar when promoting or putting down; if meet accident; wire cable rupture on the back(ing) bar; steel rope on the back(ing) bar and the application force between the steel rope on the fender guard and antagonistic force will disappear so; this moment, action of reset spring can produce a pulling force between ratchet; past drop-down ratchet; closely be buckled together mutually up to ratchet and pawl; this moment, ratchet maintained static; and ratchet because with the ratchet anchor shaft between be by being threaded; so ratchet is the squeezed air-damping spring always; because damping spring provides a positive pressure to the constant force cheese; when positive pressure was equal with the back(ing) bar own wt, this moment, stage lamp stopped to continue down to drop, thereby played the effect of protection.
In a preferred embodiment, described steel wire disk center is provided with the centre hole that passes for described ratchet anchor shaft, the centre hole of described steel wire disk and described ratchet anchor shaft surface are provided with the keyway that matches, and the centre hole of described steel wire disk is captiveed joint by the key of being located in the keyway with described ratchet anchor shaft.Purpose is to guarantee can firmly to captive joint between steel wire disk and the ratchet anchor shaft.
The beneficial effects of the utility model are: simple in structure, reasonable in design, can guarantee effectively that the steel rope when back(ing) bar breaks when falling, and in time stop stage lamp down to fall, solved an insurmountable difficult problem in the past.Description of drawings
