Preferably, the anti-falling mechanism of lifting table also includes connecting panel, and telescoping cylinder is connected with connecting panel, and rope one end is connected with connecting panel, and the other end is connected on connecting panel after an above wheel flutter connects a plurality of swinging gear.
Preferably, in the anti-falling mechanism of lifting table, telescoping cylinder is in the center of lifting table table top.
Preferably, in the anti-falling mechanism of lifting table, swinging gear and latch segment are arranged symmetrically with about lifting table table top line of centers.
Preferably, in the anti-falling mechanism of lifting table, swinging gear is two steering track rods, and each steering track rod one end is fixedly connected with rope, and the other end and latch segment are articulated as one, and latch segment is connected with the lifting table table top by rotating shaft.
Preferably, in the anti-falling mechanism of lifting table, rope is two, every corresponding four wheel flutters of rope, and connect five swinging gear.
Preferably, in the anti-falling mechanism of lifting table, four wheel flutters are positioned at rectangular four angles, and the line of centers of oblong Width overlaps with the line of centers of lifting table table top length direction; On the line of centers that in five swinging gear, is arranged on lifting table table top length direction, in all the other four, two arrange along lifting table table top length direction, be positioned on the line of centers of oblong length direction simultaneously, and about lifting table table top length direction line of centers symmetry; Two other arranges along lifting table mesa width direction, and about lifting table table top length direction line of centers symmetry.
Preferably, in the anti-falling mechanism of lifting table, telescoping cylinder is connected with normal-open electromagnetic valve.
Preferably, in the anti-falling mechanism of lifting table, telescoping cylinder is the double acting Gas spring cylinder.
Beneficial effect of the present invention:
Telescoping cylinder is connected with a plurality of latch segments with swinging gear by rope, drive the swinging gear motion under the motion of flexible telescoping cylinder, and then the location status of control latch segment, when lifting table arrives a certain floor, the part of latch segment is inserted in the default crack of floor, when lifting table will continue to move, latch segment is fully retracted in the platform table top.
The accompanying drawing explanation
The structural representation that Fig. 1 is the selected embodiment of the present invention.
In figure 1, telescoping cylinder, 2, wheel flutter, 3, the lifting table table top, 4, latch segment, 5, steering track rod, 6, rope, 7, connecting panel, 8, normal-open electromagnetic valve, 9, source of the gas, 10, rotating shaft, the line of centers of a, lifting table table top length direction, the line of centers of b, oblong length direction.
The specific embodiment
Better understand the present invention for the ease of those skilled in the art, below in conjunction with the drawings and specific embodiments, the present invention is described in further details, following is only the exemplary protection scope of the present invention that do not limit.
With reference to accompanying drawing 1, a kind of anti-falling mechanism of lifting table, comprise telescoping cylinder 1, above rope 6, a plurality of swinging gear and an a plurality of latch segment 4, rope 6 is connected with telescoping cylinder 1 and swinging gear, latch segment 4 is rotationally connected with lifting table table top 3, each latch segment 4 is corresponding connects a swinging gear, when telescoping cylinder 1 is flexible, through rope 6, pulls and drives by swinging gear that latch segment 4 stretches out or retraction lifting table table top 3.
In the present embodiment, anti-falling mechanism also includes connecting panel 7, and telescoping cylinder 1 is connected with connecting panel 7, and rope 6 one ends are connected with connecting panel 7, and the other end is connected on connecting panel 7 after an above wheel flutter 2 connects a plurality of swinging gear.
In the present embodiment, telescoping cylinder 1 is in the center of lifting table table top 3.
In the present embodiment, swinging gear and latch segment 4 are arranged symmetrically with about lifting table table top line of centers.
In the present embodiment, swinging gear is two steering track rods 5, and each steering track rod 5 one end is fixedly connected with rope 6, and the other end and latch segment 4 are articulated as one, and latch segment 4 is connected with lifting table table top 3 by rotating shaft 10.
In the present embodiment, rope 6 is two, every corresponding four wheel flutters 2 of rope 6, and connect five swinging gear.Four wheel flutters 2 are positioned at rectangular four angles, and the line of centers of oblong Width overlaps with the line of centers a of lifting table table top length direction; On the line of centers a that in five swinging gear, is arranged on lifting table table top length direction, in all the other four, two arrange along lifting table table top length direction, the line of centers b that simultaneously is positioned at the oblong length direction is upper, and about the line of centers a symmetry of lifting table table top length direction; Two other arranges along lifting table mesa width direction, and about the line of centers a symmetry of lifting table table top length direction.
In the present embodiment, telescoping cylinder 1 is the double acting Gas spring cylinder, with the tracheae connection source of the gas 9 of normal-open electromagnetic valve 8.
During lifting table work, normal-open electromagnetic valve 8 is in the energising closed condition, and now latch segment 4 pulls swinging gear to make latch segment 4 in lifting table table top 3 by telescoping cylinder 1 return drive rope 6, does not affect the lifting table normal operation; As lifting table breaks down or the platform descending speed exceeds setting speed, this telescoping cylinder 1 stretches out swinging gear makes latch segment 4 outside lifting table table top 3, lifting table table top 3 is drop in the crack that is positioned at floor set in advance by latch segment 4, prevent the 3 pendant ends of lifting table table top.
Below only described groundwork of the present invention and preferred implementation, those skilled in the art can make many changes and improvements according to foregoing description, and these changes and improvements should belong to protection scope of the present invention.
