Detailed description of the invention
below in conjunction with accompanying drawing, technical scheme of the present invention is further elaborated.
following in the description in direction, all with in operating personal operating process, the viewed top of sight line for " on ", below is D score, left side is " left side ", right side is " right side ", be just " front " to dead ahead viewed during elevator with operating personal, otherwise be " afterwards ".
a kind of building hoist derailing safety guard; this elevator comprises the bogie girder 3 and cage girder 2 that arrange along the vertical direction, and this safety guard comprises the some safety catch axis mechanisms 1 be arranged on bogie girder 3 and cage girder 2 leading flank.
shown in Figure 1, each safety catch axis mechanism 1 includes gear shaft 10 and stay bearing plate 11, and this gear shaft 10 is arranged on cage girder 2 or bogie girder 3 along self axial on even keel, and this stay bearing plate 11 is supported on the axle side of gear shaft 10.Here, this gear shaft 10 has two at least, and described gear shaft 10 is uniform intervals distribution along the longitudinal direction on stay bearing plate 11.
this bogie girder 3, cage girder 2 are also provided with the positioning support frame plate group for installing gear shaft 10, shown in Fig. 2, Fig. 3, this positioning support frame plate group is corresponding with the position of safety catch axis mechanism 1.Each positioning support frame plate group includes otic placode 20, two pieces location, the two pieces of location otic placode 20 be located on bogie girder 3 or cage girder 2 arranged on left and right sides plate and extends forward along the Width of respective place side plate respectively.Location otic placode 20 is also provided with mounting hole 201 for installing gear shaft 10, this mounting hole 201 to offer position corresponding with the installation site of gear shaft 10.
in this example, one end of gear shaft 10 offers outside thread, and this protection device for installing also comprises the jam nut matched with the outside thread on gear shaft 10.After gear shaft 10 is successively through two pieces of location otic placodes 20 of both sides relative on bogie girder 3 or cage girder 2, by jam nut, gear shaft 10 is locked, thus this safety catch axis mechanism 1 is fixed on bogie girder 3 or cage girder 2.
in this example, this bogie girder 3, cage girder 2 are all be made up of the channel-section steel of interior crimping.In order to improve the fastness of safety catch axis mechanism 1 further, strengthen the safety of this safety guard, here, at bogie girder 3, the Width of the involute avris of cage girder 2 is also welded with brace panel 21, see Fig. 2, shown in Fig. 3, the setting position of this brace panel 21 and the installation site phase one_to_one corresponding of safety catch axis mechanism 1, railway carriage or compartment type structure is formed between this brace panel 21 and bogie girder 3 or cage girder 2, when making this safety catch axis mechanism 1 stressed, acting point is whole bogie girder 3 or cage girder 2, thus effectively improve the holding capacity of this safety guard, make this safety catch axis mechanism 1 not yielding, safety is higher.In this example, two gear shafts 10 are included in each safety catch axis mechanism 1, this gear shaft 10 have employed that diameter is Φ 30,45# steel after modifier treatment is made, make the intensity enhancing of gear shaft 10, itself and integrally welded rear insertion of stay bearing plate 11 locate otic placode 20, are fixed by jam nut and bogie girder 3 or cage girder 2.Have employed the safety catch axis mechanism 1 that many gear shafts 10 are made, its intensity is higher, and safety factor is better.
above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
