Description
Technical field
The utility model relates to a kind of blocking apparatus that building hoist and the interlock system between the floor protective door are tackled the travel switch of the corresponding installation of building hoist upper and lower sides face of being used for.
Background technology
5.2.15 regulation " the electric or mechanical interlock of layer Men Yingyu cage of GB10055-2007 " building hoist safety procedure ".Only when the cage base plate was in a certain flat-bed vertical distance ± 0.25m that boards, this flat-bed layer door can be opened.", a large amount of technical schemes has appearred for satisfying this mandatory provision.Yet investigation finds, conventional art is less to find application in reality is implemented (in actual the enforcement 80% above building hoist not mounting layer door and cage interlock system).Analysis conventional technology, its groundwork all are to allow or stop the lifting operation of building hoist to reach the purpose that layer door and cage are interlocked by the induction and the open and-shut mode of carrier bed door.Can be divided into according to its conduction pattern: photo-electric, electromagnetic type, mechanical type etc.Wherein photo-electric and electromagnetic type are owing to the reliability that exists camp site operating environment abominable (mortar, dust, sewage are more) that its conducted interference is caused reduces, abominable operating environment causes that its fault rate is higher, technical sophistication, the more high reason of cost are failed by extensive promotion and application.The traditional mechanical formula is owing to adopt direct rigidity induction conduction, and the alerting ability that has limited flip flop equipment causes the series technique defective." construction elevator and the introduction of floor protective door interlock system " (author: Han Bing, Li Weiyi) designed solution (hereinafter referred " prior art scheme ") of publishing just like " building safety " 2004 the 9th phases of available technology adopting mechanical type conduction.Prior art construction elevator and floor protective door interlock system are as shown in Figure 1, at the inboard of elevator cage 1 ' (avoiding cable side) welding one metallic support, the suitable position of support is installed a limit switch 4 ', and the normally closed contact of limit switch 4 ' is connected with elevator cage 1 ' gate interlock limit switch, on the door pillar 3 ' that elevator adheres to or on the floor flat-bed shelf, fix a spring stop 5 ' then.The principle of work of this interlock system is: when floor protective door 2 ' is closed, spring stop 5 ' is by 2 ' the extruding rotation of floor protective door, bump less than limit switch 4 ', elevator cage 1 ' can start, when floor protective door 2 ' is not closed, under the effect of the back stretch of spring 6 ', spring stop 5 ' rotation presses limit switch 4 ' and cuts off lift circuit, and elevator cage 1 ' can't be started.
Because its conduction pattern is owing to adopt direct rigidity inductive layer door open and-shut mode, its flip flop equipment must be installed (the prior art scheme is arranged on the door pillar limit with it) near layer door.Analyze the prior art scheme, there is following technological deficiency in it: it is the single open-door situation that the prior art scheme only adapts to the floor door, and influenced by place, camp site space-constrained, field investigation is found to be set to double door more than 70%, thereby its range of use is subjected to bigger restriction; Oad is big, constant installation.
To sum up, prior art mechanical type layer door interlock extensively promoted and used owing to the series technique defective.
