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 lifting table table top by rotating shaft.
Preferably, in the anti-falling mechanism of lifting table, rope is two, corresponding four wheel flutters of every root rope, and connects 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 in lifting table land length direction; In five swinging gear, one is arranged on the line of centers in lifting table land length direction, in all the other four, two are arranged along lifting table land length direction, be positioned on the line of centers of oblong length direction simultaneously, and symmetrical about lifting table land length direction line of centers; Two other is arranged along lifting table mesa width direction, and symmetrical about lifting table land length direction line of centers.
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 double acting Gas spring cylinder.
Beneficial effect of the present invention:
Telescoping cylinder is connected with swinging gear and multiple latch segment by rope, under the motion of flexible telescoping cylinder, drive swinging gear to move, and then control the location status of latch segment, when lifting table arrives a certain floor, a part for latch segment is inserted in the default crack of floor, when lifting table will continue motion, latch segment is fully retracted in tabletop of platform.
Accompanying drawing explanation
Fig. 1 is the structural representation that the present invention selectes embodiment.
In figure 1, telescoping cylinder, 2, wheel flutter, 3, 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 in a, lifting table land length direction, the line of centers of b, oblong length direction.
Detailed description of the invention
Better understand the present invention for the ease of those skilled in the art, be described in further details below in conjunction with the drawings and specific embodiments to the present invention, following is only exemplary do not limit protection scope of the present invention.
With reference to accompanying drawing 1, a kind of anti-falling mechanism of lifting table, comprise telescoping cylinder more than 1, one rope 6, multiple swinging gear and multiple latch segment 4, rope 6 is connected with telescoping cylinder 1 and swinging gear, latch segment 4 and lifting table table top 3 are rotationally connected, each latch segment 4 correspondence connects a swinging gear, is pulled through swinging gear drives latch segment 4 to stretch out or retraction lifting table table top 3 when telescoping cylinder 1 stretches through rope 6.
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 end is connected with connecting panel 7, and the other end is connected on connecting panel 7 after more than one wheel flutter 2 connects multiple 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, corresponding four wheel flutters 2 of every root rope 6, and connects 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 in lifting table land length direction; In five swinging gear, one is arranged on the line of centers a in lifting table land length direction, in all the other four, two are arranged along lifting table land length direction, be positioned on the line of centers b of oblong length direction simultaneously, and symmetrical about the line of centers a in lifting table land length direction; Two other is arranged along lifting table mesa width direction, and symmetrical about the line of centers a in lifting table land length direction.
In the present embodiment, telescoping cylinder 1 is double acting Gas spring cylinder, and the tracheae with normal-open electromagnetic valve 8 connects source of the gas 9.
During lifting table work, normal-open electromagnetic valve 8 is in energising closed condition, within now latch segment 4 drives rope 6 to pull swinging gear to make latch segment 4 be in lifting table table top 3 by telescoping cylinder 1 return, does not affect lifting table and normally works; To break down as lifting table or platform descending speed exceeds setting speed, this telescoping cylinder 1 stretches out swinging gear makes latch segment 4 be in outside lifting table table top 3, make lifting table table top 3 by latch segment 4 drop to set in advance be positioned in the crack of floor, prevent lifting table table top 3 from falling the end.
Above only describes 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.
