Technical scheme of the present invention is: a kind of two fork angles keep and the instantaneous relase device, mainly comprise upper pendulum bar, swivel plate, draft link, lower beam register pin, draft link block, voussoir, pin, pin seat etc.; The top of upper pendulum bar is connected with balance staff, and the lower end of upper pendulum bar and a kind of special swivel plate are hinged; The center of rotation of swivel plate is hinged on the upper pendulum bar, and an end is connected with the register pin of draft link, makes the double pendulum bar keep angle constant in motion process; Draft link and upper pendulum bar are hinged, can rotate mutually; Fixedly there is block the side of draft link, can regulate angle between two bars by the voussoir of different angles; The pin device comprises pin seat and pin, and the pin seat is fixed on the side frame; Pin is connected with the pin seat, and when pin collided the other end of swivel plate, swivel plate rotated and register pin breaks away from, and makes two forks be in free state in moment; Pin is bent, does not influence the swing of two bars in the process of the test.
Two fork angles of the present invention keep being formed by the plow-steel making with the upper pendulum bar of instantaneous relase device, and the upper end of upper pendulum bar is connected with balance staff, can relatively rotate; The lower end of upper pendulum bar is connected by bearing pin with draft link, also can relatively rotate.
Two fork angles of the present invention keep being formed by the plow-steel making with the swivel plate of instantaneous relase device, and swivel plate is two pronged shape, and rotation center is connected by bearing pin with upper pendulum bar, can relatively rotate; One end of swivel plate has U-shaped groove, may be stuck on the register pin of draft link, and with the fixed angle of last draft link, when swivel plate rotated, the swivel plate draw-in groove can leave the draft link register pin, made draft link moment freedom.
Two fork angles of the present invention keep being formed by the plow-steel making with the draft link assembly of instantaneous relase device, comprise compositions such as draft link, draft link register pin, draft link block; Draft link is connected with upper pendulum bar by bearing pin, and the draft link register pin is fixed on a side of draft link; The draft link block is fixed on the opposite side of draft link.
Two fork angles of the present invention keep being made by plow-steel with the voussoir of instantaneous relase device and form, and are placed between draft link and the draft link block, and the deadweight by draft link is pressed in voussoir on the draft link block; Voussoir is provided with different models, by changing the voussoir of different model, can regulate the angle between the fork up and down.
Two fork angles of the present invention keep being formed by the plow-steel making with the pin device of instantaneous relase device, comprise pin, pin seat etc.; The lever seat is fixed on the frame of side; Pin is connected on the pin seat, when pin is stirred swivel plate, swivel plate is rotated, and pin bending does not automatically simultaneously influence the continuation swing of two bars.
