Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
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 safe fall-proof lifting table, comprises 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 at three edges, is provided with protective grille 11, and one side guardrail is wherein 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 to walk 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 a part for 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 at three edges, is provided with protective grille, and the main platform of Area Ratio is smaller, inside that can the main platform of indentation.On main platform and assistance platform, be all provided with flat board.A plurality of antifriction-bearing boxs 21 are installed in the both sides of assistance platform 2, antifriction-bearing box installation direction has vertical and horizontal, coordinate formation linear guide rail structure with the straight line chute on main platform, can realize like this assistance platform to the pull of 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 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 is during in indentation state, overall volume is very little, and compact conformation is convenient to walking; When the two is when stretching out state, can actv. expand 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 is during in erectility, the other end of strut bar 5 is 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.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 picks up the ears to be formed by the annular steel ring welding, and can conveniently fasten the safety belt.
Using method is as follows:
First lifting table integral body is transported to work place, then will in assistance platform autonomous platform, extract out, form a table top that work top is wider, then main platform is risen to suitable position, workman can carry out work in assistance platform, also can move to assistance platform and carry out operation outward, in this course, workman need to use auxiliary safety strap, and safety strap is tied up on picking up the ears of door-shaped frame, can prevent the generation of personnel's falling accident.
Embodiment recited above is described preferred implementation of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; relevant technical staff in the field, to various distortion of the present utility model and improvement, all should expand in protection domain as determined in the utility model claims.
