Abstract
The invention relates to a telescopic guardrail for a household elevator. The telescopic guardrail comprises a car, the top end of the car is fixedly connected with a lower guardrail and an upper guardrail nested in the lower guardrail, upper uprights and lower uprights are provided with circular through holes, and bolts are arranged between the upper uprights and the lower uprights. The lower guardrail is composed of the lower uprights connected by angular steel and a lower crossbeam fixedly connected on the sides of the lower uprights, the upper guardrail is composed of the upper uprights connected by angular steel and an upper crossbeam fixedly connected on the sides of the upper uprights, the upper uprights are nested in the lower uprights, the upper crossbeam is provided with a long switch baffle plate and a short switch stopper, the lower crossbeam is provided with a plurality of safety switches, and a warning sign is arranged on the lower crossbeam. The telescopic guardrail has the advantages that safety in use is enhanced, and depth of the elevator shaft can be reduced by adjustment of the up-down structure.
Description
technical field:
The present invention is a kind of household ladder car top guard, relates to elevator technology field.
background technology:
in elevator industry, due to the particularity of household ladder structure, car top guard is generally whole car vertex, and secondary high point general distance guardrail top also has one section of larger distance.In order to meet safety requirements, during maintenance, guardrail height is at least 700mm, has a significant impact elevator hoistways headroom height.
summary of the invention:
Technical matters to be solved by this invention is: provide a kind of household ladder car top guard device, to strengthen the safety of elevator reparing and to reduce the height of elevator hoistways top layer.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of household ladder Telescopic guardrail, include car, conveniently use, further, the top of described car is fixedly connected with lower guardrail and is nested on upper pillar stand and lower pillar stand described in the upper guardrail in lower guardrail and is provided with multiple manhole, is provided with latch between upper pillar stand and lower pillar stand.
In order to strengthen the intensity of guardrail, further, described lower guardrail forms by with the interconnective lower pillar stand of angle steel and the cross sill that is fixedly connected on lower pillar stand side, described upper guardrail forms by with the interconnective upper pillar stand of angle steel and the entablatrance that is fixedly connected on upper pillar stand side, and described upper pillar stand is nested in lower pillar stand.
In order to strengthen safety, further, described entablatrance is provided with long switch baffle plate, short switch block, described cross sill is provided with multiple safety switch, described cross sill is provided with Warning board.
Compared with prior art, usefulness of the present invention is: provide a kind of household ladder Telescopic guardrail, enhance the safety of use, by the adjustment of up-down structure, also can decrease the degree of depth of elevator hoistways.
accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is axonometric drawing of the present invention.
In figure: 1, car; 2, lower guardrail; 3, upper guardrail; 4, angle steel; 5, lower pillar stand; 6, cross sill; 7, upper pillar stand; 8, entablatrance; 9, long switch baffle plate; 10, short switch block; 11, safety switch; 12, Warning board; 13, manhole; 14, latch.
detailed description of the invention:
Describe the present invention below in conjunction with the drawings and the specific embodiments:
A kind of household ladder Telescopic guardrail according to Fig. 1, include car 1, the top of described car 1 is fixedly connected with lower guardrail 2 and the upper guardrail 3 be nested in lower guardrail 2, described lower guardrail 2 forms by with the interconnective lower pillar stand 5 of angle steel 4 and the cross sill 6 that is fixedly connected on lower pillar stand 5 side, described upper guardrail 3 forms by with the interconnective upper pillar stand 7 of angle steel 4 and the entablatrance 8 that is fixedly connected on upper pillar stand 7 side, described upper pillar stand 7 is nested in lower pillar stand 5, described entablatrance 8 is provided with long switch baffle plate 9, short switch block 10, described cross sill 6 is provided with multiple safety switch 11, described cross sill 6 is provided with Warning board 12, described upper pillar stand 7 and lower pillar stand 5 are provided with multiple manhole 13, latch 14 is provided with between upper pillar stand 7 and lower pillar stand 5.
During use, in time being in normal operating condition, upper pillar stand 7 is retracted in lower pillar stand 5 completely, going up guardrail 3 so is just properly fit onto on lower guardrail 2, long switch baffle plate 9 and short switch block 10 just touch on safety switch 11 completely, and latch 14 will be inserted in the circular hole through hole 13 of the coincidence of upper pillar stand 7 and lower pillar stand 5; If elevator will overhaul, just upper pillar stand 7 is extracted in lower pillar stand 5, until long switch block 9 and short switch block 10 depart from safety switch 11 completely, now whole electric loop is cut off, elevator is in maintenance halted state, then is inserted into by latch 14 in the manhole 13 of coincidence of upper pillar stand 7 and lower pillar stand 5.
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.
