Abstract
The utility model discloses a kind of cage top overhauling automatic switch, comprise body, described body is provided with the rotor switch of normally closed output and the human inductor module of normally closed output, and described rotor switch is divided into normal and maintenance two grades, and described human inductor module is arranged on just to the position of gate.During the utility model normal condition, rotor switch is in human inductor module normally closed output state of connecting, before being in service mode door and being opened and maintainer do not enter elevator, the normally closed output of human inductor module becomes open circuit and exports, then elevator enters service mode, and the safety of maintainer is guaranteed.
Description
Technical field
The utility model relates to a kind of lift appliance, is specifically related to a kind of cage top overhauling automatic switch.
Background technology
Elevator, as a special equipment, needs regular maintenance, M R.Usually all service switch is provided with, in order to regulate running state at machine room control housing and sedan-chair top.Usually when elevator is after entering service mode, can only run with the speed of maintenance (low speed), to ensure the safety of maintainer.Therefore, necessarily require maintainer after entering sedan-chair top, during Men Weiguan, elevator will enter service mode.Can have following situation: 1, maintainer's general idea, enter elevator and first close the door, close in front of the door for service switch is dialed into service mode, elevator moves with normal speed; 2, door switch lost efficacy, and enter elevator door and do not close, elevator also can proper motion.Maintainer is in abnormally dangerous working environment.
Summary of the invention
For solving the problem, the purpose of this utility model is to provide a kind of cage top overhauling automatic switch, realizes automatically entering inspecting state by the connection form of rotor switch and human inductor module, not only convenient but also safety.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of cage top overhauling automatic switch, comprise body, described body is provided with the rotor switch of normally closed output and the human inductor module of normally closed output, and described rotor switch is divided into normal and maintenance two grades, and described human inductor module is arranged on just to the position of gate.
The beneficial effects of the utility model are:
During the utility model normal condition, rotor switch is in human inductor module normally closed output state of connecting, before being in service mode door and being opened and maintainer do not enter elevator, the normally closed output of human inductor module becomes open circuit and exports, then elevator enters service mode, and the safety of maintainer is guaranteed.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of specification sheets, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.Detailed description of the invention of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the connection schematic diagram of rotor switch and human inductor module in Fig. 1.
Number in the figure illustrates:
1, body, 2, rotor switch, 3, human inductor module.
Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
See Fig. 1, shown in Fig. 2, a kind of cage top overhauling automatic switch, comprise body 1, described body 1 is provided with the rotor switch 2 of normally closed output and the human inductor module 3 of normally closed output, described rotor switch 2 is divided into normal and maintenance two grades, described human inductor module 3 is arranged on just to the position of gate, described rotor switch 2 is normally closed output state of connecting with described human inductor module 3 connection, it is now normal condition, before being in service mode door and being opened and maintainer do not enter elevator, the normally closed output of human inductor module becomes open circuit and exports, then elevator enters service mode, ensure that the safety of maintainer.
The foregoing is only the preferred embodiment of utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
