Technical Field
The embodiment of the invention relates to the technical field of elevator maintenance, in particular to an elevator maintenance control circuit and an elevator.
Background
The design standard of an elevator maintenance loop mainly relates to car roof maintenance, car interior maintenance and machine room maintenance. The priority of the three maintenance loops is firstly the safety of the maintenance personnel on the top of the car, then the maintenance personnel in the car and finally the maintenance personnel in the machine room. The car roof is the most preferred, because the car roof is dangerous relative to the interior of the car and a machine room, and the safety of maintainers cannot be guaranteed. Secondly, when the maintenance personnel in the sedan are operating, if the maintenance personnel in the machine room and the sedan top perform maintenance, no reaction exists, and the safety of the maintenance personnel in the sedan is effectively protected.
However, if the maintainer enters the shaft to be overhauled, the operation can be carried out only through car top overhauling, the operation is not convenient and fast enough, and in the overhauling process, the safety of the maintainer in the pit cannot be guaranteed.

In the embodiment of the invention, when the pit and the car top of the elevator are overhauled simultaneously, firstly the safety of pit maintainers is ensured, and then the safety of car top maintainers is ensured, namely the priority of pit overhaul is higher than that of car top overhaul. Specifically, referring to fig. 1, the voltage at the first power source VCC may be set to 24V. When the normally closed first car top maintenance switch SZD-1 and the normally closed first pit maintenance switch SZP-1 are pressed down simultaneously, the 24V voltage at the first power supply VCC can not reach the point A through a loop, namely the elevator is in a maintenance state, and the car top and the pit are maintained simultaneously; the third ceiling service switch SZD-3 linked with the first ceiling service switch SZD-1 is closed, the second pit service switch SZP-2 linked with the first pit service switch SZP-1 is closed, the 24V voltage at the first power source VCC reaches the J point through the second pit service switch SZP-2, and the third ceiling service switch SZD-3.
At the moment, if the first car roof slow-up switch SDS-1 and the first pit slow-up switch SPS-1 are synchronously pressed down, the second car roof slow-up switch SDS-2 linked with the first car roof slow-up switch SDS-1 is closed, the 24V voltage at the first power supply VCC reaches a point B through the second car roof slow-up switch SDS-2 and the first pit slow-up switch SPS-1, the elevator
This application has realized when the sedan-chair top and the pit of elevator overhaul simultaneously, and only the sedan-chair top and the pit move simultaneously from top to bottom slowly, and the elevator just can move from top to bottom slowly, has effectively guaranteed pit maintainer and sedan-chair top maintainer's personal safety. In the process of simultaneously overhauling the car roof and the pit, if only the slow-up switch or the slow-down switch of the car roof is pressed and the slow-up switch or the slow-down switch of the pit is not pressed, the 24V voltage at the first power supply VCC can not reach the

In the embodiment of the invention, the
For example, referring to fig. 2, when the normally closed first car top maintenance switch SZD-1 and the normally closed first pit maintenance switch SZP-1 are pressed simultaneously, the 24V voltage at the first power source VCC cannot reach point a through the loop, that is, the elevator is in a maintenance state, and the car top and the pit are maintained simultaneously; the third ceiling service switch SZD-3 linked with the first ceiling service switch SZD-1 is closed, the second pit service switch SZP-2 linked with the first pit service switch SZP-1 is closed, the 24V voltage at the first power source VCC reaches the J point through the second pit service switch SZP-2, and the third ceiling service switch SZD-3.

Illustratively, as shown in fig. 2, when the pit of the elevator is repaired, the normally closed first pit maintenance switch SZP-1 is turned off, the 24V voltage at the first power source VCC cannot reach the point a, and the elevator is in a maintenance state. The normally open second pit maintenance switch SZP-1 and the normally open third pit maintenance switch SZP-3 are closed, the 24V voltage at the first power supply VCC reaches the H point through the normally closed fourth car top maintenance switch SZD-4, when the first pit public switch PCM-1 and the first pit slow-up switch SPS-1 are pressed simultaneously, the 24V voltage at the first power supply VCC reaches the B point through the second pit slow-up SPS-2 switch, and the elevator starts to run slowly; the same principle is operated under slow speed.
Exemplarily, as shown in fig. 2, when the car roof of the elevator is overhauled, the normally closed first car roof overhaul switch SZD-1 is turned off, the 24V voltage at the first power source VCC cannot reach the point a through the loop, the elevator is in an overhaul state, the normally open points of the normally open second car roof overhaul switch SZD-2 and the normally open third car roof overhaul switch SZD-3 are closed, the 24V voltage at the first power source VCC reaches the point E through the normally closed first pit overhaul switch SZP-1, when the first car roof common switch SCM-1 and the first car roof slow-up switch SDS-1 are pressed simultaneously, the 24V voltage at the first power source VCC reaches the point B through the loop, and the elevator starts to run slowly; the same principle is operated under slow speed.

In particular, with reference to fig. 3, the following operations can be implemented by the service control circuit of the elevator shown in fig. 3: when a pit, a car roof and a machine room of the elevator are respectively and independently maintained, the slow ascending and descending of the elevator can be realized; when the pit and the car top are maintained at the same time, and the public switches at the pit and the car top act at the same time, the elevator can act up and down slowly only when the switches at the top and the bottom are closed at the same time; when the pit and the machine room are maintained at the same time, only the relevant switches at the pit can control the operation of the maintenance control circuit; when the car roof and the machine room are in maintenance at the same time, only the relevant switch at the car roof can control the loop to operate; when the pit, the car roof and the machine room are all in maintenance, maintenance control of the machine room is not needed to be considered, the action rules when the pit and the car roof are simultaneously in maintenance are referenced, the public switches at the pit and the car roof act simultaneously, the switches on the car roof and the pit are closed at the same time, and the elevator can act up and down slowly.
The application provides an overhaul control circuit of elevator has following advantage: when the pit and the car roof of the elevator are maintained by workers at the same time, the public switches of the car roof and the pit need to be pressed down at the same time, then the slow up-down switches at the car roof and the pit are closed synchronously, the elevator can go up and down slowly, and the safety of the maintenance personnel at the pit and the car roof is guaranteed; the overhaul condition of the elevator is controlled in the pit through the overhaul control circuit by the overhaul personnel, so that the elevator can be overhauled in the pit by the overhaul personnel, and the working efficiency is improved; the safety of pit maintainers is improved; the priority of pit maintenance is higher than that of car top maintenance.
