Description
Technical Field
The utility model relates to the field of safety protection equipment for tire production, in particular to a safety interlock control device for identifying the number of personnel in an overhead garage.
Background
As is well known, factory maintenance personnel enter an elevated warehouse to work, safety lock devices are generally used for guaranteeing the safety of the operators, after an elevated warehouse door is opened, operation cannot be started through interlocking devices, the personnel are effectively protected, injury to the personnel is avoided, but the safety locks are used for enabling multiple persons to enter the elevated warehouse to work, and when the persons leave the elevated warehouse, the risks of closing the safety locks and starting equipment when other persons leave exist. At this time, it is important to determine whether all the entering persons have left, and the safety lock device is not activated by any person in the overhead garage.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides the safety interlocking control device for identifying the number of people in the overhead warehouse, which not only can display the number of people in the overhead warehouse, but also can judge the number of people entering and exiting the overhead warehouse through a system, and when people continue to work or patrol in the overhead warehouse, the equipment cannot start to operate, so that the personal safety of the work is ensured.
The technical scheme adopted for solving the technical problems is as follows: a safety interlocking control device for identifying the number of personnel in an overhead vertical warehouse is provided with an overhead vertical warehouse safety door and is characterized in that an overhead vertical warehouse door safety lock is arranged on a door page and a door frame of the Gao Jiali warehouse safety door, a personnel in-out collector support is arranged on the inner side of the Gao Jiali warehouse safety door and is leveled with the door frame, a personnel in-out count collector is arranged on the personnel in-out collector support, the personnel in-out count collector is provided with an inner detection switch and an outer detection switch, an audible-visual alarm is arranged above the Gao Jiali warehouse safety door, an electronic screen is arranged outside the door page, a door closing identification switch is arranged on the door page and the door frame of the Gao Jiali warehouse safety door, and the door closing identification switch, the personnel in-out count collector, the audible-visual alarm and the electronic screen are communicated with a PLC control system.
The utility model has the advantages that the equipment is forbidden to be started under the condition that personnel exist in the warehouse through system interlocking by judging the personnel number of inspection, maintenance and the like entering and exiting the Gao Jiali warehouse and displaying the real-time personnel number in the warehouse through the electronic screen, so that the safety of the personnel in the warehouse is ensured.
Drawings
The utility model will be further described with reference to the drawings and examples.
FIG. 1 is a schematic diagram of the structure of the present utility model.
In the figure, 1, an overhead vertical warehouse safety door, 2, an overhead vertical warehouse door safety lock, 3, a door closing identification switch, 4, an in-out personnel counting collector, 5, an in-out personnel collector bracket, 6, an audible and visual alarm, 7, a PLC control system and 8, an electronic screen.
Detailed Description
In the figure, the overhead vertical garage safety door 1, the overhead vertical garage door safety lock 2, the door closing identification switch 3, the personnel counting and collecting device 4, the personnel collecting device bracket 5, the audible and visual alarm 6, the PLC control system 7 and the electronic screen 8 are in communication with the PLC control system 7.
The Gao Jiali warehouse door safety lock 2 is arranged on a door page and a door frame of the Gao Jiali warehouse safety door 1 and is communicated with the PLC control system 7, when inspection and maintenance personnel need to enter an overhead warehouse for operation, after the Gao Jiali warehouse door safety lock 2 is opened, an opening signal of the overhead warehouse door safety lock 2 is communicated to the PLC control system 7, and the PLC control system 7 sends out an instruction to stop the operation of equipment; the personnel inlet and outlet collector bracket 5 is arranged in the interior of the Gao Jiali warehouse safety door 1 and is leveled with door frames on two sides, and the personnel inlet and outlet collector 4 is arranged above the personnel inlet and outlet collector bracket; the in-out personnel counting collector 4 is provided with an inner detection switch and an outer detection switch, when the outer switch detects signals firstly and the inner switch detects signals later, the situation that personnel enter the overhead vertical warehouse is judged, the number of personnel in the overhead vertical warehouse is increased by 1, when the inner switch detects signals firstly and the outer switch detects signals later, the situation that the personnel leave the overhead vertical warehouse is judged, the number of the personnel in the overhead vertical warehouse is reduced by 1, the existing number of the personnel in the overhead vertical warehouse is calculated and recorded, the number is communicated to the PLC control system 7, and the prompt is carried out through the electronic screen 8; the door closing identification switch 3 is arranged on a door page and a door frame of the Gao Jiali garage safety door 1 and detects the closing action of the overhead garage safety door 1; when the inspection and maintenance personnel work is completed, the overhead vertical garage safety door 1 is ready to exit, when the overhead vertical garage safety door 1 is closed, the detection range of a door closing identification switch is reached, the door closing identification switch sends a signal and communicates to the PLC control system 7, if other personnel in the Gao Jiali garage still are inspecting or working at the moment, the calculated personnel number in the overhead vertical garage is not zero, the audible and visual alarm 6 is arranged above the Gao Jiali garage safety door 1, the audible and visual alarm 6 sends warning light and voice that the Gao Jiali garage is occupied, the door closing is forbidden, and the door closing and the operation personnel are warned; the electronic screen 8 is arranged outside the door page, and the number of people in the overhead garage is checked by observing the electronic screen 8; the control device cannot start operation through the PLC control system 7. If no other personnel in the Gao Jiali warehouse are patrolling or working at this time, the number of personnel in the warehouse is zero, the door locking condition is met, no warning is sent out, the personnel can close the overhead vertical warehouse door safety lock 2, and the equipment is started.
