Described lifting mechanism is scissor-type lifting mechanism.
In the lower end of described lifting mechanism, be provided with an automatic traveling mechanism.
The invention has the beneficial effects as follows: at first possess the flexible function of horizontal direction, platform can be extended to the place ahead, personnel are delivered to the place ahead, meet the requirement of certain span construction.Have a upright door-shaped frame, can hang staff's safety line, and be connected with safety rope, assistance platform or the operating personal of walking out assistance platform form an actv. protection, prevent falling accident.By this anti-fall platform is arranged on any jacking equipment and can uses, be particularly useful for having on the jacking equipment of automatic walking function, greatly improved the scope of its use.
The accompanying drawing explanation
Fig. 1 is front view of the present invention;
Fig. 2 is the front view of anti-fall platform;
Fig. 3 is the transparent view of anti-fall platform;
Fig. 4 is the schematic diagram of the platform after simplifying.
In figure: 1 main platform, 11 protective grille, 12 bodies, 13 foot of ladders, 2 assistance platforms, 21 antifriction-bearing boxs, 3 lifting mechanisms, 4 door-shaped frames, 41 pivot joints, 42 pick up the ears, 5 strut bars, 51 pins.
The specific embodiment
As shown in Figures 1 to 4,
A kind of safe fall-proof lifting table, comprise main platform 1 and assistance platform 2.
Main platform 1 is a steel structure, adopts square steel steel pipe and Plate Welding to form, and is provided with protective grille 11 at three edges, and one side guardrail wherein is provided with a body 12, and is provided with auxiliary upper and lower foot of ladder 13, facilitates that personnel's is upper and lower.These structures and existing platform are basic identical.Main platform lower end is for being connected with lifting mechanism, and lifting mechanism 3 is scissor-type lifting mechanism.In the lower end of lifting mechanism, be provided with an automatic traveling mechanism, form self-propelled safe fall-proof lifting table.By traveling gear, can drive lifting table walks arbitrarily.Traveling gear wherein can be existing friction-type, chain-type traveling gear, and any traveling gear with automatic walking function can be used, and is the part of prior art, can select according to client or actual requirement of engineering.
Assistance platform 2 is also a steel structure, adopts square steel steel pipe and Plate Welding to form, and is provided with protective grille at three edges, and Area Ratio master platform is smaller, inside that can indentation master platform.On main platform and assistance platform, all be provided with flat board.A plurality of antifriction-bearing boxs 21 are installed in the both sides of assistance platform 2, the antifriction-bearing box installation direction has vertical and horizontal, with the straight line chute on main platform, coordinate the formation linear guide rail structure, can realize like this pull of assistance platform to a side, form the drawing structure of drawer-like formula.And the flexible end position between two platforms arranges the dowel hole of pairing, by a locating dowel pin, just can realize both are fixed into to one, form locating pin structure.Hold intelligiblely, assistance platform has two states with respect to main platform: stretch out state and indentation state, when the two was in the indentation state, overall volume was very little, and compact conformation is convenient to walking; When the two is in while stretching out state, can actv. enlarge the area of work top.
At door-shaped frame 4 of the outer end of assistance platform 2 pivot joint, door-shaped frame 4 comprises two columns and a crossbeam, the bottom of two columns and assistance platform pivot joint 41, and door-shaped frame is collapsible, has level and upright two kinds of ultimate limit states.At two strut bars 5 of inner pivot joint of assistance platform 2, when door-shaped frame was in erectility, the other end of strut bar 5 was by pin 51 and door-shaped frame slip-knot, form an oblique support, improve the strong degree of door-shaped frame, when needs keep flat door-shaped frame, cancel strut bar and get final product.Door-shaped frame has folding and upright two states like this.On door-shaped frame, have fasten the safety belt pick up the ears 42, this pick up the ears by the welding annular steel ring form, can conveniently fasten the safety belt.
Using method is as follows:
At first lifting table integral body is transported to work place, then will in the assistance platform autonomous platform, extract out, form the table top that work top is wider, then main platform is risen to suitable position, the workman can carry out work in assistance platform, also can move to assistance platform and carry out operation outward, in this course, the workman need to use auxiliary safety strap, safety strap is tied up to upper the getting final product of picking up the ears of door-shaped frame, can prevent the generation of personnel's falling accident.
Embodiment recited above is described the preferred embodiment of the present invention; not scope of the present invention is limited; design under the prerequisite of spirit not breaking away from the present invention; the relevant technical staff in the field, to various distortion of the present invention and improvement, all should expand in protection domain as determined as the claims in the present invention book.
