Abstract

The utility model discloses a movable lifting operating platform, which comprises a square base. Four universal wheels are installed at the four corners of the square base. Four steel angles with an inward groove respectively are welded at the four corners of the square base. Two handles are respectively welded at the upper ends of the two steel angles on the front side and at the upper ends of the two steel angles on the rear side. A square table top which can slide up and down is inlaid in the grooves of the four steel angles. A lifting mechanism which is used for driving the table top to be lifted up and lowered down is arranged between the square base and the square table top. Since the square table top is inlaid on the internal sides of the four steel angles, is lifted up and lowered down through the lifting mechanism and can be lowered down when various containers are carried, the square table top is convenient, effort-saving, safe and reliable to operate; the square table top can also be adjusted to different heights to meet different operation requirements; and since the lifting mechanism consists of a lead screw, two transverse shafts, four upper supporting rods and four lower supporting rods, the structure is simple, the design is ingenious and lifting operation can be realized by manually rocking a rocking handle.

Description

Mobile descending operation platform

Technical field

The utility model relates to a kind of elevating instrument, relates to a kind of mobile descending operation platform specifically.

Background technology

In the laboratory or the workshop of the biochemical processes container that often needs liquid will be housed move to certain position and height, but the container that liquid in most cases is housed is all very heavy, need the several people jointly it to be lifted, sometimes in the container that needs to move dangerous chemical is housed, operating has certain danger, so just need the container that a kind of elevating instrument is equipped with liquid to lift.The workshop of laboratory or biochemical processes often uses a kind of hydaulic lift platform in the prior art, its formation comprises base, drive surface and hydraulic-driven part, there is following problems in the hydaulic lift platform of conventional confguration in the prior art: the bay-lift unbalance stress, poor stability, cause bearing surface to rock through regular meeting, thereby influence the reliability of hydaulic lift platform operation; Hydaulic lift platform of the prior art often all is to be fixed on a place, and is immovable, uses just very inconvenient like this.How to provide a kind of simple in structure, good stability and transportable descending operation platform to become the urgent demand of people.

The utility model content

The purpose of this utility model is to overcome bay-lift unbalance stress of the prior art, poor stability, and immovable defective provides a kind of mobile descending operation platform of simple in structure, good stability.

The purpose of this utility model realizes by following scheme: a kind of mobile descending operation platform, comprise plinth, four cardan wheels are installed under four angles of plinth, four angle steel that groove is inside of welding on four angles of plinth, weld handle respectively at two angle steel of front side and two angle steel upper ends of rear side, groove at four angle steel is embedded in a square mesa that can slide up and down, and is a lifting mechanism that drives the table top lifting between plinth and square mesa.

Described lifting mechanism comprises a long transverse axis and a short horizontal, the two ends of long transverse axis and short horizontal are a hinged lower fulcrum bar and a upper rack posts respectively, four lower fulcrum bars are hinged on the plinth, four upper rack posts are hinged under the square mesa, and the top has wind and the opposite leading screw of two ends hand of spiral to be installed on the nut pipe of long transverse axis and short horizontal centre.

Described cardan wheel is the cardan wheel with braking mechanism.

Advantage of the present utility model is: square mesa of the inboard embedding of four angle steel of the present utility model, square mesa can reduce table top by the lifting mechanism Lifting platform when loading various container, easy to operate, saves strength, and is safe and reliable.It can also adjust square mesa to different height, adapts to different job requirements.Described lifting mechanism is made of a leading screw, two transverse axis, four lower fulcrum bars and four lower fulcrum bars, simple in structure, design ingenious, manually wind can be realized descending operation, and need not join lockout mechanism in addition square mesa is stably stopped at various height, horizontal and vertically can both keep stable.

Description of drawings

Fig. 1 moves the perspective view of descending operation platform for the utility model;

Among the figure: 1. cardan wheel, 2. plinth, 3. angle steel, 4. square mesa, 5. handle, 6. wind, 7. leading screw, 8. short horizontal, 9. long transverse axis, 10. nut pipe, 11. lower fulcrum bars, 12. upper rack posts.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further.

As shown in Figure 1, a kind of mobile descending operation platform, comprise plinth 2, four cardan wheels 1 with braking mechanism are installed under four angles of plinth 2, four angle steel 3 that groove is inside of welding on four angles of plinth 2, welding handle 5 respectively at two angle steel 3 of front side and two angle steel 3 upper ends of rear side, be embedded in a square mesa that can slide up and down 4 at the groove of four angle steel 3, is a lifting mechanism that drives the table top lifting between plinth 2 and square mesa 4.Described lifting mechanism comprises a long transverse axis 9 and a short horizontal 8, the two ends of long transverse axis 9 and short horizontal 8 are a hinged lower fulcrum bar 11 and a upper rack posts 12 respectively, four lower fulcrum bars 11 are hinged on the plinth 2, four upper rack posts 12 are hinged on square mesa 4 times, and the top has wind 6 and the opposite leading screw 7 of two ends hand of spiral to be installed on the nut pipe 10 of long transverse axis 9 and short horizontal 8 centres.

Should be noted that at last; above content is only in order to the explanation the technical solution of the utility model; but not to the restriction of the utility model protection domain; the simple modification that those of ordinary skill in the art carries out the technical solution of the utility model or be equal to replacement does not all break away from the essence and the scope of technical solutions of the utility model.
