Detailed description of the invention
below in conjunction with accompanying drawing, technical scheme of the present invention is further elaborated.
shown in Fig. 1, Fig. 2, a connecting device for building hoist drive system 200 and cage 100, comprises cage girder 1, is positioned at bogie girder 2 above cage girder 1, is arranged between cage girder 1 with bogie girder 2 for boatswain chair 3 that both are connected.
this boatswain chair 3 is made up of screw rod and the boatswain chair plate body be located on screw rod bottom, and here, this screw rod and boatswain chair plate body are that to have employed the mode of welding integrated, thus make boatswain chair 3 reliably safer.The upper end of this cage girder 1 offers mounting groove 10, boatswain chair 3 is longitudinally plugged in mounting groove 10 by boatswain chair plate body and is connected with cage girder 1, firm in order to ensure installation, here, boatswain chair plate body and mounting groove 10 all offer pin shaft hole, and by bearing pin 6, boatswain chair plate body and mounting groove 10 is fixedly connected.This bogie girder 2 is also provided with base plate 20, and the screw rod on this boatswain chair 3 axially wears by after base plate 20 along self, adopts hexagonal opening nut to be positioned on bogie girder 2 by boatswain chair 3.This connecting device also comprises and being set on screw rod for preventing the elastic component 4 of cage 100 and drive system 200 hard contact.Here elastic component 4 comprises and being set on screw rod and the many groups belleville spring 4 laid respectively on base plate about 20 two side position.
here, boatswain chair 3 is adopted to be connected (shown in Figure 2) between cage girder 1 with bogie girder 2, make elevator in operational process, the inconsistent phenomenon produced between drive system 200 and cage 100 can servo-actuated adjustment voluntarily, eliminate impedance phenomenon, simultaneously, by arranging belleville spring 4 on boatswain chair 3, make elevator in operational process, for flexibly connecting between drive system 200 and cage 100, effectively prevent drive system 200 focus of producing when work and be directly passed to cage 100, cause significantly vibrations and noise, alleviate seismaesthesia during braking, improve cage 100 and run central comfort level, particularly in the process of high-speed cruising, feel particularly outstanding.
in order to prevent, boatswain chair 3 ruptures, bearing pin 6 lost efficacy, the phenomenon causing cage 100 to fall occurs, in the present embodiment, this connecting device also comprises the cage otic placode 11 be installed on cage girder 1, be installed in the connecting panel 5 that bogie otic placode 21 on bogie girder 2 and two ends are connected with cage otic placode 11, bogie otic placode 21 respectively.This connecting panel 5 has two pieces, lays respectively at the left and right sides of cage otic placode 11 and is connected (shown in Figure 2) by bearing pin.This bogie otic placode 21 also offers strip shape mounting hole, and one end of this connecting panel 5 is slidably connected on bogie otic placode 21 along the length bearing of trend of this mounting hole, and the other end of this connecting panel 5 is connected on cage otic placode 11 rotationally.By above set-up mode, make that there is between connecting panel 5 and bogie otic placode 21 certain upstream and downstream momentum, when elevator normally works, connecting panel 5 does not stress, when occur that bearing pin 6 lost efficacy, boatswain chair 3 ruptures or the screw rod on boatswain chair 3 and occur between jam nut sliding tooth etc. unexpected time, this connecting panel 5 can slippage on bogie otic placode 21, guarantees that drive system 200 can not be separated with cage 100, avoids the phenomenon that cage 100 falls and occurs.
here, this cage girder 1 and bogie girder 2 all have employed interior lipped channel and make, thus achieve boatswain chair 3 and be arranged on cage girder 1 in the mode of straight cutting, adopt which to install boatswain chair 3, make boatswain chair 3 reliably safer.Meanwhile, what here this boatswain chair 3 adopted is that 45# steel after modifier treatment is made, and makes the intensity enhancing of boatswain chair 3.
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.
