Abstract
The invention discloses a lift well crawling ladder device, which is fixedly mounted on the wall of a lift well. The lift well crawling ladder device comprises a crawling ladder body and a crawling ladder handrail located above the side of the crawling ladder body, wherein the crawling ladder body comprises two bilaterally symmetric side beams, a plurality of cross beams are distributed between the side beams, and at least two fixed components are fixedly connected to the side beams and the crawling ladder handrail. The lift well crawling ladder device is relatively simple in integral structure, low in manufacturing cost and simple in manufacturing process; by arranging the specific handrail, the safety and the stability of the crawling ladder device are further improved.
Description
technical field:
the present invention relates to a kind of elevator shaft ladder device.
background technology:
Nowadays all can elevator pit be set in elevator installation, and according to related elevator requirement, need to arrange snubber in pit, the parts such as track base, and certain degree of depth will be had, with meet car rush to summit or squat the end time, there are enough spaces and safe buffering distance, the pit that enters conveniently is installed or maintenance, need to provide suitable climbing ladder apparatus can enter pit from bottom, and front climbing ladder apparatus is on the market general, and all opposed configuration is comparatively complicated, cost of manufacture is higher and do not have specific handrail to arrange, in upper and lower cat ladder process, safety factor reduces.
summary of the invention:
The technical problem to be solved in the present invention be to provide a kind of can structure simpler, sturdy and durable and relatively easy and be provided with the elevator shaft ladder device of special armrest.
For solving the problem, the present invention is achieved by the following technical solutions:
A kind of elevator shaft ladder device, be fixed on elevator shaft wall, described climbing ladder apparatus comprises cat ladder body and is positioned at the cat ladder handrail above cat ladder base side, described cat ladder body comprises symmetrical two curb girders, many crossbeams are had by arranged evenly between described curb girder, described curb girder and cat ladder handrail are all fixedly connected with at least 2 fixtures, described climbing ladder apparatus overall structure is relatively simple, cost of manufacture is low and production process simple, and specific handrail arranges the security and stability further increasing climbing ladder apparatus.
As preferably, for making described elevator shaft ladder device overall structure more firm durable, described curb girder is connected with adopting to be welded and fixed between crossbeam.
As preferably, for making described elevator shaft ladder device more firmly be fixed on well enclosure, described cat ladder body and position, cat ladder handrail upper, middle and lower are provided with 3 fixtures, the effect of multiple fixture, climbing ladder apparatus is stablized more durable, safety factor is enhanced.
As preferably, described fixture adopts steel square structure, and one end is fixed on described cat ladder body and cat ladder handrail side, and the other end is fixed on well enclosure.
As preferably, adopt between described fixture and well enclosure and cat ladder body, cat ladder handrail and be bolted connection, thus make to be connected between climbing ladder apparatus with well enclosure more closely with firmly.
As preferably, durable for making described climbing ladder apparatus can stablize in practice, nor the lifting running space of elevator itself can be had influence on, the at right angle setting distance of described cat ladder body and cat ladder handrail and well enclosure is 30mm-50mm.
Compared with prior art, usefulness of the present invention is: the structure that described elevator shaft ladder device adopts cat ladder body and special cat ladder handrail to combine, cat ladder body crossbeam and measurement are welded, cat ladder body and cat ladder handrail are anchored in well enclosure by fixture, and therefore, structure is comparatively simple, fabrication and installation operation is less, cost-saving, and enhance the safety of turnover hoistway of staff, therefore can extensively be used more widely.
accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the present invention is further described:
Fig. 1 is the plan structure schematic diagram of the present invention when being arranged on well enclosure
Fig. 2 is cat ladder body Facad structure schematic diagram of the present invention
Fig. 3 is cat ladder handrail Facad structure schematic diagram of the present invention
In figure: 1, well enclosure; 2, cat ladder body; 3, cat ladder handrail; 4, curb girder; 5, crossbeam; 6, fixture.
detailed description of the invention:
Describe the present invention below in conjunction with the drawings and the specific embodiments:
A kind of elevator shaft ladder device of the present invention, as shown in Figure 1 to Figure 3, be fixed on elevator shaft wall 1, comprise cat ladder body 2 and be positioned at the cat ladder handrail 3 above cat ladder body 2 side, described cat ladder body 2 comprises symmetrical two curb girders 4, many crossbeams 5 are fixedly connected with by arranged evenly between described curb girder 4, preferably, crossbeam 5 and to measure between 4 connected mode for being welded and fixed herein, thus make described hoistway ladder stand device overall structure more firm solid, in addition described curb girder 4 and cat ladder handrail are all fixedly connected with at least 2 fixtures 6, preferably, described fixture 6 adopts steel square structure, one end is bolted on described cat ladder body 2 and cat ladder handrail 3 side, the other end is also bolted on well enclosure 1, quantity is set to 2, namely on cat ladder body 2 and cat ladder handrail 3, lower two positions are provided with 2 fixtures, thus described elevator shaft ladder device more firmly can be fixed on well enclosure 1 and strengthen the safety factor of cat ladder, in addition, described cat ladder body 2 and cat ladder handrail 3 are 30mm-50mm with the at right angle setting distance of well enclosure 1, thus it is durable to make described climbing ladder apparatus can stablize in practice, nor the lifting running space of elevator itself can be had influence on, have more applicability, in actual fabrication, described cat ladder body 2 and cat ladder handrail 3 all adopt steel angle structure, sheet metal component bending is adopted to form, thus cost of manufacture is lower with making intensity, overall structure is relatively simple, and specific handrail arranges the security and stability further increasing climbing ladder apparatus.
It is emphasized that: be only preferred embodiment of the present invention above, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
