The specific embodiment
Whole driving machine is designed to move integral body and fixed slide rail base two parts; The both sides of slide rail base portion are two slide rail bases (201) that are arranged in parallel, and the interior survey of slide rail base (201) has upper and lower slide rail and side slide rail; The both sides, bottom of the back and front supporting plate of mobile integral part respectively are equipped with the translation position-limited wheel (111) and the restriction of a cover restriction up-and-down movement and move position-limited wheel (113) to the side of two lateral movements; Translation position-limited wheel (111) can roll along the upper and lower slide rail of surveying in the slide rail base (201), and side is moved position-limited wheel (113) and can be rolled along the side slide rail of surveying in the slide rail base (201); Make between whole mobile integral body and slide rail base two parts slide rail translation by slide rail base (201).
Be described further below in conjunction with accompanying drawing.
Fig. 1, Fig. 2 and Fig. 3 are the structural representations of the embodiment of the invention.
Between rear bearing sheet (102) and the front end panel (106) drum shaft (105) is installed; Reel (103) is installed on the drum shaft (105); Reel (103) appearance is processed with the plug helix of a constant pitch according to the stroke of the thickness of all steel ropes of topping winch (302) and suspension rod, and the just fixing back of an end of steel rope (302) is flat in these grooves, when suspension rod puts down from eminence toward the stage table top; Steel rope (302) constantly discharges again, flat around the number of turns just fewer and feweri; Motor and retarder (101) are installed in rear bearing sheet (102) and go up and to cooperate with drum shaft (105) and drive drum shaft (105), drive reel (103) rotation, pass through steel rope (302) folding and unfolding suspension rod again; Drum shaft (105) is through sprocket wheel driving wheel (107), chain (108) and sprocket wheel flower wheel (109) screw rod sprocket shaft (110) rotation.
Be set with nut support transverse slat (202) between the slide rail base (201) of the left and right sides; Nut base (203) is installed on the nut support transverse slat (202); Nut (204) is housed, nut (204) work that matches with screw rod sprocket shaft (110) on the nut base (203); During screw rod sprocket shaft (110) rotation; Drive nut (204) moves forward and backward along screw rod sprocket shaft (110) relatively; Because nut (204) is fixed, thereby screw rod sprocket shaft (110) just drives whole driving machine and moves the relative slide rail base portion of integral part and do relative translation.Because
Top in a side of slide rail base (201) is provided with assembly pulley bearing (205), is provided with pulley bracket (206) above the assembly pulley bearing (205), and quarter block (207) is installed down on the pulley bracket (206); Flat steel rope (302) on the reel (103) through quarter block (207) down, go up quarter block (301) and arrive suspension rod and remove to promote or put down suspension rod.
Because the pitch of screw rod sprocket shaft (110) goes up the consistent of steel wire rope groove pitch with reel (103); Therefore to move the speed of the speed that produces relative translation between whole and the slide rail base (201) and steel rope release consistent for whole driving machine; Following quarter block (207) remains unchanged with the position of the corresponding steel wire rope groove of reel (103), thereby steel rope is gone up stable operation in steel wire rope groove and the following quarter block (207) at reel (103) all the time.
Because the position of quarter block (207) and last quarter block (301) is fixed down; Therefore the distance between quarter block (207) and the last quarter block (301) can be provided with arbitrarily down; Promptly do not receive the influence of distance; Like this, flybar driving machine of the present invention just goes for very little installing space.
