Multiscrew multi-storey building elevator safety provided by the utility model is high, particularly with regard to provided by the utility model more The safety analysis of screw rod multi-storey building elevator is as follows:

A, anti-fall ladder

(1) the rated load 300KG of multiscrew multi-storey building elevator provided by the utility model, lifting speed 0.25m/S, It is used enough for resident in old-fashioned residential building.

(2) as design object, the self weight of carriage 2 plus rated load are total to about 8KN.

(3) when the selection short screw of T50 × 8 connects into long bolt and by the vehicle of M30 × 2 both ends male and female head, single length The pulling force that allows to carry of screw rod is 180KN.Four screw mechanisms, then 180 × 4/8=90(times of safety coefficient)

(4) carriage self weight 300kg and manned load 300kg be by 12 428 power transmissions of long filament bolt to climb nut and Screw rod.The 428 use grade bolt of M16/8.8, it is 35KN that single branch, which allows to carry pulling force,.Then 35 × 12/(3+3)=70 (times safety coefficient).

Therefore, carriage is absolutely not because more screw rods 3 are broken or stripped thread, or because 12 long filament bolts 428 are broken or Stripped thread and free falling, therefore there is no the possibility of pendant ladder for the utility model elevator.

B, preventing colliding with top

T50 stop nut is equipped at derrick top plate 50cm on every 3 top of screw rod, when carriage is out of control to derrick top plate When close, this nut oppresses machine seat board 41 and damping spring 420 first, and spring-compressed touches uplink limit switch, four limits Any one is touched i.e. to motor implementation pressure power-off in switch, and warning indicator light lights.

Therefore, this double shield of uplink is blocked with stop nut by forcing power-off to be shut down, the utility model elevator can not It rushes to summit.Since forced stoppage signal is compressed from damping spring 420, personnel have no impact feeling in carriage.

C, anti-reduction of speed

(1) drive motor uses 4 pole motors, and revolving speed can not be more than rated speed, therefore it can not draw Nut be more than design speed and rotate.Therefore, carriage can only at the uniform velocity rise under motor energized state or uniform descent moves.

(2) when motor is with carriage uniform descent, if accident power-off and motor stall, or unexpected chain rupture and Freely, carriage will continue to glide driven sprocket because of inertia at this time.Inertia force at this time=aforementioned motor power calculation In P=0.442KN, and because inertia downslide need to overcome force of sliding friction=aforementioned F=0.798KN, due to inertia force 0.442KN < force of sliding friction 0.798KN, if meet with this two accidents during cage descending, carriage can be soon Slow down and stops.

D, anti-crouching bottom

According to the analysis of above-mentioned A and C, for carriage it is not possible that bottom of squatting at a high speed due to out of control, there is no need to high crouching bottom is arranged Buffer spring, i.e., no setting is required foundation pit.(there is the space of 15cm distance between car floor and derrick footing surface, to hold Receive the cable for hanging on cage bottom.)

In order to guard against cage descending to the first floor, because of leveling electric appliance failure, still will cause slight " crouching bottom ".It uses thus Above-mentioned set 19# section end four " buffer springs " work as a buffer, be located at this time near screw end " lower limit is opened Close " can the total electricity of cutting in time, motor stalling, carriage, which is just lifted in the elasticity of " buffer spring ", lower without impacting to be stopped.

E, power failure

When drive system is damaged in operation, the phenomenon of the failure that carriage stops lifting only occurring, will not lead to any Serious accident.

It to sum up analyzes, the design of multiscrew multi-storey building elevator provided by the utility model is safe.

In addition, it is necessary to explanation, multiscrew multi-storey building elevator provided by the utility model, wherein what is used is automatically controlled System and call display box etc. can be ordered by specialized factory.

To sum up, multiscrew multi-storey building elevator provided by the utility model compared with prior art, has below beneficial to effect Fruit:

(1) elevator structure is significantly simplified, manufacturing cost is reduced；

(2) adaptability to old multi-storey building in installation and use process is improved, and can adapt to the different numbers of plies Multi-storey building installation and use；

(3) by the screw rod of four corners setting guiding carriage elevating movement in derrick, the steady of elevator operation is improved Qualitative and reliability.

It is understood that embodiment of above is merely to illustrate that the principles of the present invention and uses exemplary Embodiment, however the utility model is not limited thereto.For those skilled in the art, this is not being departed from In the case where the spirit and essence of utility model, various changes and modifications can be made therein, these variations and modifications are also considered as this reality With novel protection scope.
