The specific embodiment
The purpose of this utility model, technical scheme and useful technique effect are more clear to be understood in order to make, and below in conjunction with accompanying drawing technology contents of the present utility model and the specific embodiment is described in further detail.Should be understood that the specific embodiment of describing in this specification sheets only is in order to explain the utility model, is not in order to limit the utility model.
As shown in Figure 1; express elevator end station fender guard has comprised guide rail 7 from the bottom to top, the switch bracket 4 that is fixed together with guide rail and the inductive switch 3 that is installed in switch bracket 4 one ends; lower speed reducing switch S2 and upper speed reducing switch S1, smallest limit switch L2 and limes superiors switch L1.Wherein, the distance of switch bracket 4 and inductive switch 3 and lower speed reducing switch S2 shortens dramatically than 8 meters distance in the prior art between 2-5 rice.Do not draw among car 11(Fig. 1) move up and down along guide rail; Figure 3 shows that express elevator end station fender guard is at the birds-eye view of elevator hoistways upstation structural representation; by among the figure as can be known; the side of car 11 is equipped with car support 2 and hits bow 5; binary pair 1 is installed on the car support 2; binary pair 1 is corresponding with the position of inductive switch 3 in vertical direction, that is to say that binary pair 1 can be by the position at inductive switch 3 places when vertically moving with car.The support of car shown in Fig. 12 just illustrates with the position of binary pair 1, and this position is mobile along with the movement of car.According to shown in Figure 1, principle of work of the present utility model is as follows:
Car moves from the bottom to top, when the binary pair 1 on the car support 2 passes through the position of inductive switch 3, that is: be equivalent to the bow that hits of the prior art and trigger the deceleration detector switch, apparatus for controlling elevator begins to detect the car deceleration/decel and whether meets the default requirement, to judge whether forcing towing machine to slow down.When hitting of car side bent the lower speed reducing switch S2 of 5 shake-up, system again detected the car deceleration/decel and whether meets the setting requirement, to judge whether forcing towing machine to slow down.After hitting the upper speed reducing switch S1 of bow 5 shake-up, because S1 and S2 switch are connected in series, still can detect restriction signal so that hit bow system after leaving S2.If car is not out of service according to the retardation curve of default, car continues upwards operation, hits bow 5 and can touch smallest limit switch L2 and limes superiors switch L1, and this moment, elevator device took urgent measure, and stopped by force the elevator operation, guaranteed safety.
As shown in Figure 2, structure and Fig. 1 are basically identical, and difference is, switch bracket 4 and the inductive switch 3 that is installed in switch bracket 4 one ends are positioned at the top of speed reducing switch S1, and the distance of switch bracket 4 and upper speed reducing switch S1 is 2-5 rice.Its principle of work is as follows:
Car from top to bottom moves, when the position of the binary pair 1 on the car support 2 by inductive switch 3 (be equivalent to the bow that hits of the prior art and trigger the deceleration detector switch), apparatus for controlling elevator detects the car deceleration/decel and whether meets the default requirement, to judge whether to force towing machine to slow down, when hitting of car side bent the upper speed reducing switch S1 of 5 shake-up, system again detects the car deceleration/decel and whether meets the setting requirement, to judge whether forcing towing machine to slow down.After hitting the lower speed reducing switch S2 of bow 5 shake-up, because S1 and S2 switch are connected in series, still can detect restriction signal so that hit bow system after leaving S1, if car is not out of service according to the retardation curve of default, car continues operation downwards, hits bow 5 and can touch limes superiors switch L1 and smallest limit switch L2, and this moment, elevator device took urgent measure, stop by force the elevator operation, guarantee safety.
The utility model is provided with two speed reducing switch of S1, S2, and these two speed reducing switch are connected in series, advantage is when hitting the lower speed reducing switch S2 of bow 5 shake-up or upper speed reducing switch S1, both can work simultaneously, when car makes progress the operation of station, lower end in hoistway like this, only need to push down one of them speed reducing switch can detect restriction signal to hit bow, and actv. has shortened and hit length of bow's degree when guaranteeing elevator safety operation.
Further, in the fender guard at express elevator end station, can use the radio detection technology, produce restriction signal such as optoelectronic induction or ultrasonic sensing, come the alternative bow machinery triggering speed reducing switch that hits to produce restriction signal, so, binary pair 1 can be chosen as triggering magnet, or light trigger, or the super sonic binary pair; Correspondingly, inductive switch 3 is elected the bistable magnetic inductive switch as, or photoelectric sensor switch, or the ultrasonic sensing switch, and the utilization of high-tech detection technique also can further provide its accuracy of detection and work efficiency is provided.
The according to the above description announcement of book and instruction, the utility model those skilled in the art can also carry out suitable change and modification to above-mentioned embodiment.Therefore, the specific embodiment that discloses and describe above the utility model is not limited to also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.In addition, although used some specific terms in this specification sheets, these terms do not consist of any restriction to the utility model just for convenience of description.
