Abstract
The utility model relates to the technical field of elevator cars and particularly relates to a folding type foot protection device for a shallow pit, which comprises a car body. A foot protection board is composed of a horizontal foot board and a vertical foot board. One end of the vertical foot board is fixedly connected with a sill support in the car body, and the other end of the vertical foot board is hinged to the horizontal foot board through a hinge. The horizontal foot board is symmetrically provided with two large bosses and two small bosses. The bottom of the car body is symmetrically provided with two guide sliding grooves. One end of each supporting rod is provided with a slider matched with one corresponding sliding groove, and the other end of the supporting rod is hinged to one corresponding large boss. Each supporting rod is connected with a corresponding U-shaped rod through a corresponding connection rod. One end of each U-shaped rod is hinged to one corresponding small boss, and the other end of the U-shaped rod is connected with a foot wheel. According to the technical scheme of the utility model, the folding type foot protection device for the shallow pit can be applied to elevators with the shaft pits thereof equal to or smaller than 400 mm. In this way, not only the national regulation in Regulation on Special Equipment Safety Inspection can be met, but also the function of a foot protection bottom board in an elevator car is realized. In addition, the device is simple in structure and reasonable in setting.
Description
Technical field
The utility model relates to lift car technical field, particularly the collapsible feet guard apparatus of a kind of shallow pit.
Background technology
Elevator pit is for the parts such as energy disperser and guiderail base being installed, so both can having been ensured that lower hole operated the personal security of these parts, also can playing good buffer action.Along with the scale in city is sharply expanding, land resources is more and more deficienter, today that land price is surging, how to reduce building area that elevator takies, how to reduce the elevator pit degree of depth and become the much-talked-about topic of research in the industry.
The volume of the parts such as existing energy disperser and guiderail base is all huger, is so just difficult to use in the very shallow elevator of well pit, especially in well pit is less than or equal to the elevator of 400mm, is difficult to be applied.
Therefore be necessary existing lift car toeguard to carry out technical innovation further.
Utility model content
The purpose of this utility model is for the defect of prior art and deficiency, provides a kind of simple in structure, the collapsible feet guard apparatus of shallow pit reasonable in design, easy to use.
For achieving the above object, the technical solution adopted in the utility model is:
The collapsible feet guard apparatus of a kind of shallow pit described in the utility model, comprise car cab, two strut bars, toeguard and two U-shaped bars, described toeguard is comprised of horizontal sole and longitudinal sole, longitudinally the ground sill bracket of sole one end and car is fixedly connected, longitudinally the sole other end is hinged by hinge and horizontal sole, on described horizontal sole, be symmetrically arranged with two large boss and two small boss, large boss is all positioned at the left side of small boss; Described car cab bottom is symmetrically arranged with two guide chutes, and strut bar one end is provided with the slippery fellow who matches with guide chute, and the described strut bar other end is hinged with large boss; Strut bar is connected with U-shaped bar by connecting rod, and described U-shaped bar one end and small boss are hinged, and the described U-shaped bar other end is connected with castor.
Adopt after said structure, the utility model beneficial effect is: the collapsible feet guard apparatus of a kind of shallow pit described in the utility model, comprise car cab, two strut bars, toeguard and two U-shaped bars, described toeguard is comprised of horizontal sole and longitudinal sole, longitudinally the ground sill bracket of sole one end and car is fixedly connected, longitudinally the sole other end is hinged by hinge and horizontal sole, on described horizontal sole, be symmetrically arranged with two large boss and two small boss, large boss is all positioned at the left side of small boss; Described car cab bottom is symmetrically arranged with two guide chutes, and strut bar one end is provided with the slippery fellow who matches with guide chute, and the described strut bar other end is hinged with large boss; Strut bar is connected with U-shaped bar by connecting rod, and described U-shaped bar one end and small boss are hinged, and the described U-shaped bar other end is connected with castor.The utlity model has simple in structurely, arrange rationally.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, the collapsible feet guard apparatus of a kind of shallow pit described in the utility model, comprise car cab 1, two strut bars 3, toeguard 4 and two U-shaped bars 5, described toeguard 4 is comprised of horizontal sole 4-1 and longitudinal sole 4-2, longitudinally the ground sill bracket of sole 4-2 one end and car 1 is fixedly connected, longitudinally the sole 4-2 other end is hinged with horizontal sole 4-1 by hinge 7, on described horizontal sole 4-1, be symmetrically arranged with two large boss 8 and two small boss 9, large boss 8 is all positioned at the left side of small boss 9; Described car cab 1 bottom is symmetrically arranged with two guide chutes 2, and strut bar 3 one end are provided with the slippery fellow who matches with guide chute 2, and described strut bar 3 other ends are hinged with large boss 8; Strut bar 3 is connected with U-shaped bar 5 by connecting rod 10, and described U-shaped bar 5 one end and small boss 9 are hinged, and described U-shaped bar 5 other ends are connected with castor 6.
Principle of work of the present utility model: as shown in Fig. 2～3, in car cab 1 decline process, when castor 6 touches terrace surface, castor 6 is subject to the antagonistic force of terrace surface, this antagonistic force moves right castor 6, drive horizontal sole 4-1 to move right, until horizontal sole 4-1 and when longitudinally sole 4-2 becomes 90 to spend right angle, car cab 1 decline process finishes simultaneously.
In car cab 1 uphill process, car cab 1 is drawing laterally sole 4-1 and is being moved to the left, and castor 6 now is also and then moved to the left, until castor 6 is while leaving terrace surface, this collapsible feet guard apparatus all launches.Reciprocation cycle thus.
The utility model can be applied in well pit is less than or equal to the elevator of 400mm, the regulation that had so both met the < < special safety equipment inspection regulations > > of national regulation, can play again the function of lift car spats lower plate.In addition, this is simple in structure, reasonable in design.
The above is only preferred embodiments of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
