Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example 1
Please refer to fig. 1-2, in the embodiment of the utility model, a cage top shutdown mechanism, including base 1 and install trigger mechanism and the switching device on base 1, switching device passes through control scheme and main contactor switch electric connection, and the switching device of here mainly provides switching signal for the main contactor switch on the control scheme for main contactor switch can control opening and shutting on cage top trigger mechanism triggers during switching device, switching device provides switching signal for main contactor switch, main contactor switch control cage top shutdown.
Specifically, trigger mechanism includes running-board 2, connecting pin 5 and reset spring 6, the one end of running-board 2 is articulated through connecting pin 5 and base 1, running-board 2 can take place to rotate relative to base 1, preferably, base 1 is L shape structure, be convenient for install in the corner on cage top, and running-board 2 is equivalent to base 1's hypotenuse, when opening and stopping of cage top needs are controlled, directly trample running-board 2 can, it is very convenient, install reset spring 6 on connecting pin 5, here, reset spring 6 is preferred to be the torsional spring, the both ends of torsional spring butt respectively on running-board 2 and base 1, after trampling the completion, directly loosen running-board 2, running-board 2 can automatic the reseing.
Further, in order to prevent a person from treading the pedal 2 with force, which may damage the switch device, the base 1 is provided with an opening for accommodating a free end of the pedal 2, and certainly, the height of the opening is greater than the thickness of the pedal 2, so that the normal movement of the pedal 2 is not affected, preferably, the opening is a rectangular hole or a waist-shaped hole, which can limit the up-and-down movement of the pedal 2, and the pedal 2 acts within a certain range, so that the person in the cage top cannot affect the switch device even if the person treads the pedal 2 with excessive force or the pedal 2 opens, and the safety, reliability and effectiveness of the mechanism are always maintained.
In addition, the switch device here is a microswitch 4, the microswitch 4 is a KW3A type microswitch manufactured by southeast electronics corporation, the microswitch 4 is mounted on the base 1 through a support 3, the support 3 and the base 1 are welded or fixed through screws, and here, a trigger part of the microswitch 4 faces the pedal 2.
When the device is used, the support 1 is welded on the top of a cage, when a construction elevator is installed for the first time, the control line of the microswitch 4 is confirmed to be effectively connected into a control circuit of the construction elevator, when an operator adds or lowers sections or checks and maintains the operator to ride the construction elevator on the top of the cage, the feet of the operator on the top of the cage can be lightly placed on the pedal 2 or close to the pedal 2, at the moment, the microswitch 4 does not act because the pedal 2 is not stressed, and the cage continues to normally operate; when the machine needs to be stopped, a person on the top of the cage steps on the pedal 2 to touch the contact of the micro switch 4, a main contactor switch in a control circuit is cut off, and the cage stops running; when the shutdown state needs to be relieved, the feet of the personnel on the top of the cage leave the pedal plate 2, the pedal plate 2 recovers the original state after external force is removed, the contact of the micro switch 4 is reset, a control circuit is switched on, the construction elevator cage can normally run, in addition, the opening hole arranged on the base 1 better limits the action of the pedal plate 2 in a certain range, even if the personnel in the top of the cage pedal plate 2 excessively exert force or the pedal plate 2 is opened, the influence on the switch device can not be caused, and the safety, reliability and effectiveness of the mechanism are always kept.
