Accompanying drawing explanation
Accompanying drawing 1 is the schematic front view of the present invention;
Accompanying drawing 2 is the schematic side view of the present invention.
Embodiment
The structure of the present invention is set forth further below in conjunction with accompanying drawing.
Shown in Fig. 1-2, a kind of lift car weighing device, comprise the bearing beam 1 being fixed in elevator hoistways, the fag end plate 2 being arranged on this bearing beam 1, the hoist ropes rope head component 3 being arranged on this fag end plate 2, the support 5 being fixed on bearing beam 1 or fag end plate 2, the lever 6 that can be arranged on support 5 with rotating, the switch frame 9 being arranged on support 5 by elasticity part 11, it is contained on switch frame 9 and can forbid the vernier switch 10 that elevator normally runs after being touched, in FIG, by hoist ropes rope head component 3, the fag end 4 of hoist ropes can flexibly be strained under the action of gravity of the parts such as sedan-chair railway carriage or compartment, when the load-carrying of sedan-chair railway carriage or compartment changes, correspondingly, tension power suffered by hoist ropes fag end 4 also can change, fag end 4 is caused to rely on hoist ropes rope head component 3 that corresponding elasticity displacement occurs, in other words, the change in displacement that fag end 4 occurs reflects sedan-chair railway carriage or compartment load-carrying situation, this belongs to the conventional knowledge of dawn known to a person skilled in the art. in FIG, sedan-chair railway carriage or compartment is more heavy, then the displacement amount that fag end 4 is downward will be more big. in fig. 2, one end of lever 6 is fixedly connected by the fag end 4 of web plate 7 with hoist ropes, and like this in sedan-chair railway carriage or compartment load-carrying change, when causing fag end 4 to be subjected to displacement, correspondingly, lever 6 can rotate.Here setting sedan-chair railway carriage or compartment have no cargo conditions, loaded condition and exceed specified rated load state, when sedan-chair railway carriage or compartment is in no cargo conditions, as shown in Figure 2, lever 6 is in horizontality, has distance between lever 6 and vernier switch 10, and now vernier switch 10 is not touched; So no matter when sedan-chair railway carriage or compartment is in loaded condition, lever 6 contacts with vernier switch 10, but does not touch this vernier switch 10, the zero load of sedan-chair railway carriage or compartment or fully loaded (reaching specified rated load), then elevator all can normally use; And when sedan-chair railway carriage or compartment be in exceed specified rated load state time, lever 6 can touch vernier switch 10, cause elevator forbidden run, it is achieved overload protection. This sedan-chair railway carriage or compartment weighing device adopts the parts such as support, lever, vernier switch to realize the load-carrying situation in detection sedan-chair railway carriage or compartment, and physical construction is simple, and cost is low. No matter terraced visitor, or on goods ladder, all there is the phenomenon of fag end change in displacement reflection sedan-chair railway carriage or compartment load-carrying change, therefore this sedan-chair railway carriage or compartment weighing device can be useful on visitor's ladder, also can be useful on goods ladder.
In fig. 2, support 6 has two spaced positions 12 and 13, on position 12 or 13, lever 6 all can be installed with rotating, but the different corresponding different car load in position, adopts position 13 to install lever 6 as 1,2 ton of ladder adopts position 12 to install lever 6,3-5 ton ladder.
In FIG, web plate 7 is fixedly connected with the fag end 4 of hoist ropes, in fig. 2, web plate 7 is offered the open holes 71 that length direction extends along the vertical direction, the open holes 61 that length direction extends along the longitudinal direction is offered in one end of lever 6, bolt 14, through the open holes 61 and 71 of lever 6, web plate 7, the position passed is combined with nut, it is achieved one end of lever 6 and the fixing of web plate 7. The position of adjusting bolt 14 in open holes 61,71, then can the position of adjustment (adjusting) lever 6 one end, ensure that lever 6 is horizontally disposed with when sedan-chair railway carriage or compartment is in no cargo conditions. In fig. 2, switch frame 9 is arranged on by elasticity part 11 and connects on support plate 8, this connection support plate 8 is offered the open holes 81 that length direction extends along the vertical direction, support 5 is offered the open holes 51 that length direction extends along the longitudinal direction, bolt 15 is through the open holes 81 and 51 connecting support plate 8, support 5, the position passed is combined with nut, realize connecting support plate 8 fixing on support 5, the position of adjusting bolt 15 in open holes 81,51, then can regulate the mounting height connecting support plate 8, thus the elastic force size of adjustable elastic part 11.
This sedan-chair railway carriage or compartment weighing device, after in-site installation is good, carries out Field adjustment, regulates the relative position of web plate 7 with lever 6 when sedan-chair railway carriage or compartment is unloaded, makes lever 6 maintenance level, and adjustable elastic part 11 is to suitable height; When the car is fully loaded, with the relative position connecting support plate 8, lever 6 is substantially contacted by adjustment part support 5 with vernier switch 10; When car load exceedes specified rated load, continuation is risen by lever 6 head, causes vernier switch 10 action, plays overload provide protection; When car load returns within specified rated load, lever 6 can be separated with vernier switch 10 contact, then elevator returns to normal service condition. For organic machine room-free elevator, it is possible to directly arrive this sedan-chair railway carriage or compartment weighing device of debugging in machine room; For machine-roomless lift, operator can directly debug on sedan-chair top.
