Abstract
A TSP mixer safety interlock device comprises a first alternating current contactor, wherein a mixer driving motor is connected in series with a first alternating current contactor contact, and a first alternating current contactor coil is connected in series with at least two key switches. The utility model is used for solving the problem of personal casualty accidents caused by mistaken power transmission of the stirrer.
Description
Technical Field
The utility model relates to a safety interlocking device of a TSP (TSP) stirrer.
Background
A TSP (environmental protection impervious material) stirrer has to be manually moved into a stirring bin for cleaning because the TSP material is sticky and often easily stuck on stirring blades, resulting in a great reduction in stirring efficiency. Normally, people can cut off power and hang up a card before entering a warehouse to ensure the personal safety of the personnel entering the warehouse, but the personnel can often cause false power transmission due to various negligence to cause personal casualty accidents.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a TSP (TSP) stirrer safety interlocking device which is used for solving the problem of personal casualty accidents caused by mistaken power transmission of a stirrer.
In order to solve the problems, the technical scheme of the utility model is as follows:
a TSP mixer safety interlock device comprises a first alternating current contactor, wherein a mixer driving motor is connected in series with a first alternating current contactor contact, and a first alternating current contactor coil is connected in series with at least two key switches.
The stirrer further comprises a first alternating current contactor, a second alternating current contactor contact is connected with the first alternating current contactor contact in series, a second alternating current contactor coil is connected with a travel switch in series, the travel switch is installed on the stirrer, and a stirrer access cover triggers the travel switch.
The beneficial effects of the utility model are as follows: the two key switches are adopted to control the start and stop of the driving motor of the stirrer, so that the power supply is absolutely disconnected when personnel enter the bin, the stirring blades cannot be started, and the safety of the personnel is ensured.
Drawings
The utility model is further described with reference to the accompanying drawings:
figure 1 is a schematic view of the structure of the present utility model,
fig. 2 is a circuit diagram of the present utility model.
In the figure: a first alternating current contactor 1, a second alternating current contactor 2, a driving motor 3, a key switch 4, a travel switch 5, a stirrer 6 and an access cover 7.
Detailed Description
As shown in fig. 1 and 2, a TSP mixer safety interlock device includes a first ac contactor 1, a mixer 6 drive motor 3 connected in series with the contacts of the first ac contactor 1, and a first ac contactor 1 coil connected in series with two key switches 4.
When the automatic switching device is used, after a dispatcher and an maintainer arrive at the scene at the same time, the two key switches 4 are disconnected and the keys are pulled out, so that the contacts of the first alternating current contactor 1 are disconnected, then two keys in the two key switches 4 are respectively handed to the hands of the warehouse-in maintainer and the dispatcher, so that the maintainer can enter the stirrer 6 to clean the stirrer 6, if other people need to switch on the stirrer 6, the maintainer and the dispatcher must be found, only the maintainer comes out from the stirrer 6 and is informed of the arrival of the dispatcher, the stirrer 6 can be started only by switching on the two key switches 4, and the safety of the personnel is guaranteed.
The stirrer also comprises a first alternating current contactor 1, a contact of a second alternating current contactor 2 is connected with the contact of the first alternating current contactor 1 in series, a coil of the second alternating current contactor 2 is connected with a travel switch 5 in series, the travel switch 5 is arranged on a stirrer 6, and a stirrer access cover 7 triggers the travel switch 5. When many people get into the mixer 6 and clear up, as long as open access cover 7 at a time, then travel switch 5 just opens, makes second alternating current contactor 2 contact disconnection, and mixer 6 can't start, even like this even the maintainer that carries the key comes out from mixer 6, as long as access cover 7 does not cover, mixer 6 also can't start, only confirm in the mixer 6 to the scene nobody to the lock is gone up access cover 7, just can start mixer 6, has further ensured maintainer safety from this.
