Abstract

A collapsible lifting platform of the utility model is an overhead operation facility suitable for power supply and construction companies. The collapsible lifting platform is composed of interlinked staircase frames. The platform is characterized in that the staircase frame mentioned is interlinked two or three sections; the external staircase frame of handrail (3) is positioned on the support (6) through the shaft (5); a manual winch machine (2) is positioned on the support (6) and the rope (12) is connected with the internal staircase frame of handrail (4) through the crown block (11) on the staircase frame; a horn guide hook (10) limiting downward movement is positioned on the internal staircase frame of handrail (4); and a universal truckle (8) and an adjustable localizing support column (7) are positioned below the support (6). The platform is characterized in that the platform is made of light-weighted, high-strength, erosion-resistant and insulated fiberglass reinforced materials, which can be used at a high operation height and adjustable, and can be moved within a big scope. Therefore, the platform is of high efficiency and big scope of adaptability, and is an ideal overhead operation facility for power supply, construction and other companies.

Description

The formula of can falling lifting table

Technical field

The utility model relates to the building maintenance facility, promptly a kind of inspection platform of ascending a height.

Background technology

In departments such as building, electric power, usually needing ascends a height installs, upkeep operation, this just need by, use staircase, the platform of the usefulness of ascending a height.Existing method is to use simple long ladder or takes temporarily and make the landing stage of scaffold of ascending a height, but simply long terraced operation height is limited, takes temporarily that to make the landing stage of scaffold time-consuming again.

Summary of the invention

The utility model to provide exactly a kind of can be in a big way ascend operation, need not take the job platform of making again temporarily.This formula lifting table that can fall is made up of the staircase frame that is nested with.The staircase frame is two joint or three joints that are nested with, outer staircase frame places on the base through rotating shaft, base is provided with the hand winch machine, twisted rope is connected with interior staircase frame through the fixed pulley on the outer staircase frame, interior staircase frame is provided with and limits the goat's horn location hook that it freely glides, and universal caster wheel and adjustable positioning supports post are arranged under the base.There are antiskid pedal and guardrail in interior staircase frame upper end.This ascend operation platform is made of the galss fiber reinforced resin section bar, in light weight, intensity is high, insulation, withstanding corrosion, its base area is big, adopt adjustable positioning supports post more can enlarge Area of bearing, thereby can save the liftings in a big way of frame staircase by two joints even three, operation height is higher relatively, and can arbitrarily adjust.Another advantage is that platform and staircase part can be fallen on base around the rotating shaft on the base, and is more convenient reaching carrying on the road, displacement in a big way, to increase work efficiency.

Description of drawings

Fig. 1 is the utility model status architecture scheme drawing that fell.

Fig. 2 is the upright operating condition scheme drawing of the utility model.

Fig. 3 is a goat's horn location hook principle of work scheme drawing of the present utility model.

Among the figure, 1 capstan engine crank, 2 capstan enginees, 3 outer staircase frames, staircase frame in 4,5 base shafts, 6 bases, 7 adjustable positioning supports posts, 8 universal caster wheels, 9 antiskid pedals, 10 goat's horn location hooks, 11 fixed pulleys, 12 twisted ropes, 13 torsion springs, 14 rotating shafts, 15 swing frames, 16 rocking pins, the straight plate of 17 goat's horn location hooks, 18 decline backplates, 19 goat's horns, 21 stiles.

As shown in Figure 1 and Figure 2, the utility model formula lifting table that can fall is made up of the staircase frame that is nested with.The staircase frame is two joint or three joints that are nested with.Outer staircase frame 3 places on the base 6 through rotating shaft 5, base 6 is provided with hand winch machine 2, twisted rope 12 is connected with interior staircase frame 4 through the fixed pulley 11 on the outer staircase frame 3, and outer staircase frame 3 is provided with and limits the goat's horn location hook 10 that it freely glides, and base has universal caster wheel 8 and adjustable positioning supports post 7 for 6 times.There are antiskid pedal 9 and guardrail 12 in interior staircase frame 4 upper ends.

As Fig. 2, shown in Figure 3, during staircase frame 4, twisted rope 12 is drawn high interior staircase frame 4 in raising, and goat's horn location hook 10 is not stopped on the ground to move thereupon yet, and stile 21 location that at any time can the outer terraced frame 3 of goat's horn 19 hooks, and manhole ladder frame 4 can not descended.When needing to reduce platform manhole ladder frame 4, as long as close back earlier rope 12 slightly, the decline backplate 18 of goat's horn location hook 10 is placed on the stile 21, when staircase frame 4 descends in making again, decline backplate 18 promptly protects goat's horn 19, goat's horn location hook 10 is inwardly turned round partially, and goat's horn 19 just can slip over stile 21 unimpededly like this, and staircase frame 4 descends smoothly in making.

The utility model job platform is lifting arbitrarily both, satisfies the requirement of ascend operation, the random running fix of can falling again.Thereby be a kind of desirable practical ascend operation facility.

Claims

1, the formula lifting table that can fall, form by the staircase frame that is nested with, it is characterized in that said staircase frame is two joint or three joints that are nested with, outer staircase frame (3) places on the base (6) through rotating shaft (5), base (6) is provided with hand winch machine (2), the fixed pulley (11) of twisted rope (12) on outer staircase frame (3) is connected with interior staircase frame (4), and interior staircase frame (4) is provided with and limits the goat's horn location hook (10) that it freely glides, and universal caster wheel (8) and adjustable positioning supports post (7) are arranged under the base (6).

2, the formula lifting table that fell according to claim 1 has antiskid pedal (9) and guardrail (12) on the staircase frame (4) in it is characterized in that.
