Abstract
The utility model relates to a shaft ladder stand device for overhauling and maintaining a pit, and the device comprises ladder stand cross beams (1), ladder stand side beams (2) and fixing pieces (3), wherein the ladder stand cross beams (1) and the ladder stand side beams (2) are fixed; one ends of the fixing pieces (3) are connected with the ladder stand side beams (2) through bolt assemblies (5) and the other ends of the fixing pieces (3) are connected with steel expansion bolts (4) which are fixed on a shaft wall. According to the utility model, components of the whole shaft ladder stand are fewer, the structure is simple, and the space of the pit can be sufficiently utilized and the influences on the operation of a lift are not caused. According to the shaft ladder stand, the requirements of installation and maintenance personnel in the actual application are reasonably considered, so that the requirements of a user can be more conveniently met, the structure is simple and simultaneously the safety of the user is also ensured.
Description
Technical field
The utility model relates to a kind of hoistway cat ladder, is used for arriving elevator pit from bottom and carries out necessary parts installation or maintenance.
Background technology
Elevator pit according to the related elevator requirement, need be provided with parts such as snubber, track base, and will have certain degree of depth, when rushing to summit or squatting the end to satisfy car, enough spaces and safe buffering distance is arranged.Entering pit is for ease installed or maintenance, need provide suitable device to get into the pit from bottom.It is firm that this device needs, and simple in structure.
Summary of the invention
The utility model technical problem to be solved is, a kind of hoistway cat ladder is provided, and the hoistway cat ladder interposed structure of this structure is simple, easy to assembly, and it is smaller to occupy the space of pit.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of pit maintenance and hoistway climbing ladder apparatus of safeguarding of being used for; Comprise cat ladder crossbeam, cat ladder curb girder, fixture; Said cat ladder crossbeam, cat ladder curb girder are fixed, and said fixture one end is connected through bolt assembly with the cat ladder curb girder, and the other end is connected with the steel expansion bolt that is fixed on well enclosure.
Crossbeam of cat ladder described in the utility model and cat ladder curb girder are the angle steel section bar all, are to be formed by the sheet metal component bending that cat ladder crossbeam and the welding of cat ladder curb girder are fixing.
The climbing ladder apparatus of hoistway described in the utility model is installed on greater than the height apart from pit bottom surface 450mm.
The advantage of present technique scheme is:
1. this hoistway cat ladder simple structure, it is little to take up room.The hoistway cat ladder of present technique scheme is arranged on a side of hoistway layer door opening, and is also less apart from the distance of well enclosure, so can the operation of elevator not exerted an influence.
2. this hoistway is simple in structure, easy to assembly.In the design, crossbeam and curb girder weld together, and every crossbeam spacing is 300mm, fully take into account the convenience of vertical direction maintenance personal climbing and auxiliary movement.
3. this hoistway cat ladder structural safety is stable.Crossbeam and curb girder all are to adopt angle steel, constitute supporting frame, the weight that can bear the staff fully through welding.Fixture is fixed on well enclosure through the steel expansion bolt, satisfies requirement of strength.Integral surface all scribbles paint, can reduce the corrosion of cat ladder, avoids meeting accident.
Description of drawings
Fig. 1, Fig. 2 are the structural representations of the utility model.
Among the figure, 1 cat ladder crossbeam, 2 cat ladder curb girders, 3 fixtures, 4 steel expansion bolts and 5 bolt assemblies.
The specific embodiment
A kind of pit maintenance and hoistway climbing ladder apparatus of safeguarding of being used for; Comprise cat ladder crossbeam 1, cat ladder curb girder 2, fixture 3; Cat ladder crossbeam 1, cat ladder curb girder 2 are fixed, and fixture 3 one ends are connected through bolt assembly 5 with cat ladder curb girder 2, and the other end is connected with the steel expansion bolt 4 that is fixed on well enclosure.Cat ladder crossbeam 1 is the angle steel section bar all, is to be formed by the sheet metal component bending that cat ladder crossbeam 1 is fixing with 2 welding of cat ladder curb girder with cat ladder curb girder 2.
The hoistway climbing ladder apparatus is installed on greater than the height apart from pit bottom surface 450mm.Cat ladder crossbeam 1 constitutes the cat ladder framework with cat ladder curb girder 2 through welding, through bolt assembly 5 fixture 3 and cat ladder curb girder 2 is linked.Fixture 3 is the rectangular sheet metal component of bending, totally 4, and in the top and bottom of hoistway cat ladder, each two of left and right sides.At correct position with well pit aspect hole one side, imbed steel expansion bolt 4, fixing through the fixture in the hoistway cat ladder 3 with steel expansion bolt 4, firm being fixed on the well enclosure of then whole cat ladder.
The spirit that the utility model is created is: when satisfying the requirement of arrival well pit, adopt simple structure, and easy to assembly.In addition, the non-creativeness that those skilled in the art carries out the present technique scheme improves, and also belongs to the protection domain of this patent.
Claims (3)
1. one kind is used for pit maintenance and the hoistway climbing ladder apparatus of safeguarding; It is characterized in that: comprise cat ladder crossbeam (1), cat ladder curb girder (2), fixture (3); Said cat ladder crossbeam (1), cat ladder curb girder (2) are fixed; Said fixture (3) one ends are connected through bolt assembly (5) with cat ladder curb girder (2), and the other end is connected with the steel expansion bolt (4) that is fixed on well enclosure.
