Abstract
The invention discloses a lift car weighing device. The lift car weighing device comprises a support, a lever capable of being rotatably arranged on the support, a switch frame installed on the support through an elastic part and a micro switch which is installed on the switch frame to be able to prohibit a lift from running normally after touched. The lift car weighing device is designed according to the principle of adopting displacement changes of a hoisting rope head to reflect lift car loading conditions. When a lift car is in a state of exceeding a rated load, the lever can touch the micro switch, so that the lift is prohibited from running, and overload protection is achieved. According to the lift car weighing device, components such as the support, the lever and the micro switch are adopted to detect loading conditions of the lift car, and the lift car weighing device is simple in mechanical structure and low in cost. Rope head displacement changes reflect lift car loading changes not matter on a passenger lift or a cargo lift, and the lift car weighing device is suitable for both the passenger lift and the cargo lift.

The specific embodiment
Further set forth structure of the present invention below in conjunction with accompanying drawing.
Shown in Fig. 1-2, a kind of lift car weighting apparatus, comprise the bearing beam 1 that is fixed in the elevator hoistways, be arranged on the rope hitch plate 2 on this bearing beam 1, be arranged on the hoist ropes fag end assembly 3 on this rope hitch plate 2, be fixed on the support 5 on bearing beam 1 or the rope hitch plate 2, can be arranged on the lever 6 on the support 5 rotatably, be installed in switch frame 9 on the support 5 by elastic component 11, be contained in the micro-switch 10 that after being touched, to forbid the normal operation of elevator on the switch frame 9, in Fig. 1, by hoist ropes fag end assembly 3, make that the fag end 4 of hoist ropes can flexibly be strained under the gravity effect of parts such as car, when the car load-carrying changes, correspondingly, hoist ropes fag end 4 suffered tightening forces also can change, cause fag end 4 to rely on hoist ropes fag end assembly 3 that corresponding elastic displacement takes place, in other words, the change in displacement that fag end 4 takes place has reflected car load-carrying situation, and this belongs to the common knowledge of dawn known to a person skilled in the art.In Fig. 1, car is more heavy, and then fag end 4 downward displacements will be more big.In Fig. 2, an end of lever 6 is fixedly connected by the fag end 4 of connecting panel 7 with hoist ropes, changes in the car load-carrying like this, and when causing fag end 4 to be subjected to displacement, correspondingly, lever 6 can rotate.Here set car and have light condition, fully laden and surpass the rated load state, when car was in light condition, as shown in Figure 2, lever 6 was in horizontality, between lever 6 and the micro-switch 10 distance was arranged, and this moment, micro-switch 10 was not touched; When car was in fully laden, lever 6 contacted with micro-switch 10, but did not touch this micro-switch 10, car unloaded or fully loaded (reaching rated load) so no matter, and then elevator all can normally use; And when car was in above the rated load state, lever 6 can touch micro-switchs 10, caused the elevator operation that is under an embargo, the realization overload protection.This car weighting apparatus adopts parts such as support, lever, micro-switch to realize detecting the load-carrying situation of car, and physical construction is simple, and cost is low.No matter at elevator, or on the Cargo Lift, the phenomenon that all exists the load-carrying of fag end change in displacement reflection car to change so this car weighting apparatus can be useful on the elevator, also can be useful on the Cargo Lift.
In Fig. 2, two positions 12 and 13 that arrange are at interval arranged, on the support 6 on position 12 or 13, all lever 6 can be installed rotatably, but the different corresponding different car load in position adopt position 12 that lever 6 is installed as 1,2 ton of ladder, and 3-5 ton ladder adopts position 13 that lever 6 is installed.
In Fig. 1, connecting panel 7 is fixedly connected with the fag end 4 of hoist ropes, in Fig. 2, offer the mounting hole 71 that length direction extends along the vertical direction on the connecting panel 7, one end of lever 6 offers the mounting hole 61 that length direction extends along fore-and-aft direction, bolt 14 passes the mounting hole 61 and 71 of lever 6, connecting panel 7, is combined with nut on the position that passes, and realizes an end of lever 6 and fixing of connecting panel 7.Regulate the position of bolt 14 in mounting hole 61,71, position that then can adjustment (adjusting) lever 6 one ends guarantees that when car is in light condition lever 6 is horizontally disposed with.In Fig. 2, switch frame 9 is installed in by elastic component 11 and connects on the support plate 8, offer the mounting hole 81 that length direction extends along the vertical direction on this connection support plate 8, offer the mounting hole 51 that length direction extends along fore-and-aft direction on the support 5, bolt 15 passes the mounting hole 81 and 51 that connects support plate 8, support 5, be combined with nut on the position that passes, realize connecting support plate 8 fixing on support 5, regulate the position of bolt 15 in mounting hole 81,51, then can regulate the setting height(from bottom) that connects support plate 8, thereby regulate the elastic force size of elastic component 11.
After this car weighting apparatus installs at the scene, carry out Field adjustment, when car is unloaded, regulate the relative position of connecting panel 7 and lever 6, make lever 6 maintenance levels, and regulate elastic component 11 to suitable height; When the car at full load, by adjustment part support 5 and the relative position that is connected support plate 8 lever 6 is contacted substantially with micro-switch 10; When car load surpasses rated load, lever 6 heads will continue to rise, and cause micro-switch 10 actions, play the overload protection effect; In the time of in car load returns to rated load, lever 6 can be separated with micro-switch 10 contacts, and then elevator returns to normal operating condition.For organic machine room-free elevator, can directly arrive this car weighting apparatus of debugging in the machine room; For machine-roomless lift, operating personal can directly be debugged on the sedan-chair top.
