The specific embodiment
Embodiment: the utility model patent disclosure a kind of anti-fall device of the vertical lifting equipment with channled rail guiding, as shown in drawings, comprise that lock actuater is connected leverage with control of braking.The realization of the utility model anti-drop function is bay-lift to be stopped and be stuck in flute profile guiding rail inside by the friction force that produces between lock actuater and flute profile guiding rail medial surface to realize.
The anti-fall device of the vertical lifting equipment of present embodiment as shown in Figure 1, the lock actuater among Fig. 2 is the right elevation of the lock actuater among Fig. 1, Fig. 3 is the birds-eye view of Fig. 2.The anti-fall device of present embodiment comprises that control of braking connects lever 3 and the lock actuater 19 that is arranged in the flute profile guiding rail 1; Lock actuater 19 comprises wedge shape inside brake piece 4, two the outer slipper 5 of wedge shape, friction lining 6, pull bar 7, the outer slipper pin 8 of wedge shape, extension springs 9, goes up extension spring pull bar 10 and permanent seat 21.Control of braking connects lever 3 and comprises articulation piece 11, lever shaft 12, steel rope 14, nut 16, packing ring 20, stage clip 17 and lifter drawing bar 18.
Wedge shape inside brake piece 4, two outer slipper 5 of wedge shape all are arranged in flute profile guiding rail 1, and axially relative motion between inside and outside wedge shape slipper can not separate.Wedge shape inside brake piece 4 is captiveed joint with bay-lift 2 by permanent seat 21, and permanent seat 21 is Connection Blocks of lock actuater 19 and bay-lift 2.Two outer slipper 5 of wedge shape are arranged at the both sides of wedge shape inside brake piece 4 respectively, wedge shape inside brake piece 4 is provided with T type projection near a side of wedge shape inside brake piece 4, embed in the groove of outer slipper 5 sides of wedge shape, T type projection constitutes T type guide frame and links with groove is in the same place.The cross section of wedge shape inside brake piece 4 is trapezoidal that upper bottom surface is wide, bottom surface is narrow, and the cross section of the outer slipper 4 of wedge shape is at right angles trapezoidal, and the square edge of right-angled trapezium is parallel with flute profile guiding rail 1.It is hinged with the outer slipper pin 8 of wedge shape by the waist shaped hole of its underpart to be provided with the outer slipper 5 of 6, two wedge shapes of friction lining near a side of flute profile guiding rail 1 inner side edge on the slipper 5 outside wedge shape.The outer slipper pin 8 of wedge shape connects the lower end of extension spring 9, thereby extension spring 9 is connect with the outer slipper 5 of two wedge shapes indirectly.The upper end of extension spring 9 is connected on the wedge shape inside brake piece 4, captives joint with bay-lift 2 indirectly.
The lower end of the outer slipper pin 8 of the wedge shape of lock actuater 19 shown in Figure 2 is provided with pull bar 7, and is connected the left end that control of braking connects lever 3 by articulation piece 11.Control of braking connects lever 3 and is supported on the lever shaft 12, and lever shaft 12 is fixed on the bay-lift 2.The right-hand member that control of braking connects lever 3 is connected to lifter drawing bar 18 by steel rope 14.Be specially steel rope 14 strings between upper lift ring 15 and lower lift ring 13, lower lift ring 13 is fixed on the right-hand member that control of braking connects lever 3, and upper lift ring 15 is fixed in the lifter drawing bar 18.Lifter drawing bar 18 inserts in the hole at lifting acting point position of bay-lift 2 from the top down, and be provided with stage clip 17 in the annular space between the hole of lifter drawing bar 18 and bay-lift 2, the upper end of stage clip 17 acts on the bay-lift 2, and the lower end acts on the lifter drawing bar 18.Lifter drawing bar 18 is spacing in the space of bay-lift 2 by nut 16 and packing ring 20, and lifter drawing bar 18 and bay-lift 2 are linked together.Lifter drawing bar 18 at nut 16 and packing ring the part more than 20 can be in the hole of bay-lift 2 axial motion.Lifter drawing bar 18 upper ends link to each other with elevating chain, and when lifter drawing bar 18 was moving upward, stage clip 17 was compressed, and give bay-lift 2 force transmission by nut 16 and packing ring 20.
The working process of the anti-fall device of this vertical lifting equipment is as follows:
When bay-lift normally is connected with driving system, lifter drawing bar is moved up by the pulling force of the lifting chain of bay-lift, make the stage clip compression, under the effect of nuts and washers, the masterpiece of lifter drawing bar is used on the acting point of bay-lift, steel rope is tightened, control of braking connects lever and make counter-clockwise swing around lever shaft under the effect of steel rope, the articulation piece that control of braking connects the lever left end moves down, the pull bar that drives lock actuater moves downward, pull bar acts on the outer slipper pin of wedge shape, the outer slipper of wedge shape two wedge shapes of outer slipper pin drive moves down along the T slot of wedge shape inside brake piece, the extension spring that is connected on the outer slipper pin of wedge shape is elongated simultaneously, the reduced width of lock actuater 19, do not contact with the inner side edge of channled rail, when bay-lift normally moves up and down, do not produce friction force, the bay-lift normal operation.In this case,, guarantee to leave enough gaps between slipper and the channled rail, guarantee that lifting table moves up and down by the distance of extension spring control brake piece and guide rail inboard.
When bay-lift and driving system disconnection or the fracture of lifting chain, lifter drawing bar loses hoisting force upwards, and the stage clip of compression recovers distortion rapidly, and promotion packing ring and nut move downward lifter drawing bar, and the lineoutofservice signal pull of control of braking connection lever disappears; Control of braking connects the ineffective power of right-hand member of lever, meanwhile, extension spring is shunk because of losing pulling force, the outer slipper pin of pulling wedge shape is shunk in extension spring, driving the outer slipper of two wedge shapes moves up along T shape guide groove, outer slipper of wedge shape and wedge shape inside brake piece are moved to axial, the width of lock actuater 19 increases, and the distance between the dual-side of channled rail guide rail reduces fast, the friction lining of a side of close flute profile guiding rail contacts with the guide-track groove medial surface on the slipper outside wedge shape, produce friction, make the outer slipper of two wedge shapes, wedge shape inside brake piece and guide rail are solidified as a whole under the effect of horizontal force.Because channled rail is to maintain static, so lock actuater also with regard to stop motion, because the anti-fall device and the bay-lift of vertical lifting equipment are solidified as a whole, so bay-lift stops falling, has reached anti-fall, purpose of safety.Because the outside of the outer slipper of wedge shape is parallel with the inside groove of channled rail groove, contacting between slipper and the guide-track groove is the face contact outside the glancing impact wedge shape, its load-carrying capacity is big, channled rail there is not obvious impression, be not easy distortion, arrest accurately reliable operation, highly sensitive, can not produce excessive impact; And simple in structure, be convenient to make, be easy to realize normalisation, producing in serial form.
The above only is a preferred embodiment of the present utility model, can not limit the scope that the utility model is implemented with this, and all simple conversion of doing according to the utility model claim and description all should still belong to protection domain of the present utility model.
