Abstract
The utility model discloses an elevator cage weighing device. The elevator cage weighing device comprises a bracket, a lever, a switch frame and an inching switch, wherein the lever is arranged on the bracket in a rotating manner; the switch frame is arranged on the bracket through an elastic member; the inching switch is arranged on the switch frame and can stop normal operation of an elevator after being triggered. The elevator cage weighing device is designed by using the principle that the displacement change of the rope head of a hauling rope reflects the cage loading condition; when the cage is in a state exceeding rated load, the inching switch is triggered by the lever to stop the operation of the elevator so as to realize overload protection. According to the cage weighing device, the loading condition of the cage is detected through components such as the bracket, the lever and the inching switch; the cage weighing device has a simple mechanical structure and is low in cost. In spite of passenger elevators and goods elevators, the phenomenon that the displacement change of the rope head reflects the loading change of the cage exists, so that the cage weighing device is suitable for both the passenger elevators and the goods elevators.

utilization due to technique scheme; the utility model compared with prior art has following advantages: this lift car weighting apparatus; the change in displacement that adopts hoist ropes fag end to occur has reflected that the principle of car load condition designs; at car when surpassing rated load state; lever can touch micro-switch; cause elevator to be prohibited to move, realize overload protection.This car weighting apparatus adopts the parts such as support, lever, micro-switch to realize the load condition that detects car, and physical construction is simple, and cost is low.No matter at elevator, or on Cargo Lift, the phenomenon that all exists the load-carrying of fag end change in displacement reflection car to change, therefore this car weighting apparatus can be useful on elevator, also can be useful on Cargo Lift.
Accompanying drawing explanation
accompanying drawing 1 is looked schematic diagram for master of the present utility model;
accompanying drawing 2 is schematic side view of the present utility model.
The specific embodiment
below in conjunction with accompanying drawing, further set forth structure of the present utility model.
shown in Fig. 1-2, a kind of lift car weighting apparatus, comprise the bearing beam 1 being fixed in 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 rope hitch plate 2, can be arranged on rotatably the lever 6 on support 5, by elastic component 11, be arranged on the switch frame 9 on support 5, be contained in the micro-switch 10 that can forbid the normal operation of elevator on switch frame 9 after being touched, in Fig. 1, by hoist ropes fag end assembly 3, the fag end 4 of hoist ropes can flexibly be strained under the Action of Gravity Field of the parts such as car, when car load-carrying changes, correspondingly, the suffered tightening force of hoist ropes fag end 4 also can change, cause fag end 4 to rely on hoist ropes fag end assembly 3 that corresponding elastic displacement occurs, in other words, the change in displacement that fag end 4 occurs has reflected car load condition, this belongs to the common knowledge of dawn known to a person skilled in the art.In Fig. 1, car is heavier, and the downward displacement of fag end 4 will be larger.In Fig. 2, one end of lever 6 is fixedly connected by connecting panel 7 and the fag end 4 of hoist ropes, changes like this in car load-carrying, and while 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 rated load state, when car is during in light condition, as shown in Figure 2, lever 6, in horizontality, has distance between lever 6 and micro-switch 10, and now micro-switch 10 is not touched; When car is during in fully laden, lever 6 contacts with micro-switch 10, but does not touch this micro-switch 10, and so no matter car is unloaded or fully loaded (reaching rated load), and elevator all can normally be used; And when car is when surpassing rated load state, lever 6 can touch micro-switch 10, cause elevator to be prohibited to move, realize overload protection.This car weighting apparatus adopts the parts such as support, lever, micro-switch to realize the load condition that detects car, and physical construction is simple, and cost is low.No matter at elevator, or on Cargo Lift, the phenomenon that all exists the load-carrying of fag end change in displacement reflection car to change, therefore this car weighting apparatus can be useful on elevator, also can be useful on Cargo Lift.
in Fig. 2, on support 6, have on 12 He13， positions 12 or 13, two spaced positions, all lever 6 can be installed rotatably, but the different corresponding different car load in position, install lever 6 as 1,2 ton of ladder adopts position 12, 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, on connecting panel 7, offer the mounting hole 71 that length direction extends along the vertical direction, one end of lever 6 offers the mounting hole 61 that length direction extends along fore-and-aft direction, bolt 14, through the mounting hole 61 and 71 of lever 6, connecting panel 7, is combined with nut on the position passing, and realizes one end of lever 6 and fixing of connecting panel 7.Adjusting bolt 14 is in mounting hole 61 ,71Zhong positions, and position that can adjustment (adjusting) lever 6 one end guarantees that at car lever 6 is horizontally disposed with during in light condition.In Fig. 2, switch frame 9 is arranged on and is connected on support plate 8 by elastic component 11, on this connection support plate 8, offer the mounting hole 81 that length direction extends along the vertical direction, on support 5, offer the mounting hole 51 that length direction extends along fore-and-aft direction, bolt 15 is through the mounting hole 81 and 51 that connects support plate 8, support 5, on the position passing, be combined with nut, realize and connect support plate 8 fixing on support 5, adjusting bolt 15 is in mounting hole 81 ,51Zhong positions, can regulate the setting height(from bottom) that connects support plate 8, thereby the elastic force of adjustable elastic part 11 is big or small.
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 adjustable elastic part 11 is to suitable height; When 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 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 elevator returns to normal operating condition.For there being machine room elevator, can directly arrive this car weighting apparatus of debugging in machine room; For machine-roomless lift, operating personal can directly be debugged on sedan-chair top.
