Abstract
The utility model discloses a cat ladder device for going in/out a lift pit, which includes a cat ladder and a mounting frame, wherein the mounting frame is provided with first supporting plates connected with a shaft enclosure of a lift and second supporting plates connected with a guiding rail of the lift; the first and the second supporting plates are connected with mounting plates through bolts; a pair of calipers is connected onto each mounting plate; and the cat ladder is clamped and mounted on the calipers. According to the utility model, the mounting space of the guiding rail bracket is utilized to improve the utilization ratio of the shaft; the cat ladder is not needed to be fixed on the shaft any longer, thereby lowering the requirement for the shaft, and compared with the cat ladder device fixed on the shaft, the cat ladder device with the structure is lower in cost.
Description
Technical field
The utility model relates to a kind of climbing ladder apparatus, relates in particular to a kind of be used to entering the elevator hoistways hole climbing ladder apparatus at the end.
Background technology
Elevator is a kind of vertical transportation instrument that runs in the building, is bearing the vital task of transport of passengers and goods.The pit of elevator hoistways is equipped with the parts such as snubber, and for ease of the installation of these parts and Inspection and maintenance in the future, every elevator must arrange can be convenient to the climbing ladder apparatus that the staff passes in and out pit.The pit ladder device is the requisite ingredient of whole elevator device.In order to satisfy some specific demands, there are some elevators to adopt six guide rail structures.The elevator of six guide rail structures, centre are backbones, and both sides are secondary rails, and secondary rail is generally all relatively near door opening.Car area and the load-carrying of this class elevator are all larger, hoistway space relative compact, the hoistway space less that remaining part can take on the elevator.The climbing ladder apparatus of turnover pit generally is that ladder is fixed on the hoistway side by expansion bolt, and it is larger to take up room, and has reduced the utilization rate of hoistway, causes the waste of hoistway space.In order to cooperate the installation of pit ladder, elevator hoistways need to have corresponding collar tie beam or concrete wall, has increased to a certain extent cost.
The utility model content
The utility model provides a kind of climbing ladder apparatus that passes in and out elevator pit in order to solve problem related in the background technology.
The technical solution of the utility model is: a kind of climbing ladder apparatus that passes in and out elevator pit, comprise cat ladder and mounting bracket, described mounting bracket is provided with the first supporting plate that is connected with elevator shaft wall and the second supporting plate that links to each other with cage guide, described the first supporting plate and the second supporting plate are bolted gripper shoe, be connected with a pair of clamp on the described gripper shoe, described cat ladder clamping is in described a pair of clamp.
As a kind of preferred, described the second supporting plate is by pressing guide plate to link to each other with cage guide.
As a kind of preferred, described the first supporting plate is provided with mutually perpendicular two locating surfaces, and a described locating surface and elevator shaft wall fit, and described another locating surface and gripper shoe fit.
As a kind of preferred, described the first supporting plate is connected with elevator shaft wall by expansion bolt.
As a kind of preferred, described the first supporting plate is made by angle steel.
As a kind of preferred, described gripper shoe is provided with the installing hole that passes for for bolt, and described installing hole is strip or long waist type.
In sum, the utlity model has following advantage:
The utility model has been used the installing space of rail brackets, thereby has improved the hoistway utilization rate; Cat ladder need not be fixed on the hoistway again, reduced to hoistway with respect to the climbing ladder apparatus that is fixed on the hoistway, the climbing ladder apparatus cost of this structure is lower.
Description of drawings
Fig. 1 is the present embodiment schematic diagram.
The specific embodiment
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of climbing ladder apparatus that passes in and out elevator pit, comprise cat ladder 1 and mounting bracket 2, described mounting bracket 2 is provided with the first supporting plate 11 that is connected with elevator shaft wall and the second supporting plate 12 that links to each other with cage guide, described the first supporting plate 11 and the second supporting plate 12 are bolted gripper shoe 13, be connected with a pair of clamp 14 on the described gripper shoe 13, described cat ladder 1 clamping is in described a pair of clamp 14.Described the second supporting plate 12 is by pressing guide plate a to link to each other with cage guide.Described the first supporting plate 11 is provided with mutually perpendicular two locating surfaces, and a described locating surface and elevator shaft wall fit, and described another locating surface and gripper shoe 13 fit.Described the first supporting plate 11 is connected with elevator shaft wall by expansion bolt.Described the first supporting plate 11 is made by angle steel.Described gripper shoe 13 is provided with the installing hole that passes for for bolt, and described installing hole is strip or long waist type.
Product of the present utility model is assembled two or more sets (can cheat end depth adjustment according to hoistway) mounting brackets 2 and install in use, then cat ladder is filled 1 and sandwiches in the clamp 14, and so cat ladder 1 just is fixed, so that the staff conveniently enters.Mounting bracket 2 when mounted, at first by expansion bolt the first supporting plate 11 is linked to each other with elevator shaft wall, and with the second supporting plate 12 by pressing guide plate a to link to each other with cage guide, install subsequently gripper shoe 13, last according to the spacing between the good a pair of clamp 14 of the width adjusting of cat ladder 1 and install, at last cat ladder 1 clamping is entered to get final product.The width that the utility model has the advantages that cat ladder is consistent with the width of lift car, has used the installing space of rail brackets, thereby has improved the hoistway utilization rate; Ladder need not be fixed on the hoistway again, has reduced the requirement to hoistway, and with respect to the climbing ladder apparatus that is fixed on the hoistway, the climbing ladder apparatus cost of this structure is lower.
More than explanation only is to explanation of the present utility model, so that complete enforcement this programme of those of ordinary skills' energy, but be not to restriction of the present utility model, those skilled in the art can make the modification that does not have creative contribution to present embodiment as required after reading this manual, these all are not creative modifications.But as long as in claim scope of the present utility model, all be subject to the protection of Patent Law.
