Abstract
The invention discloses an interlocking control circuit of a coal briquette chain plate conveyor. The interlocking control circuit comprises a first branch and a second branch. The first branch is formed by connecting a first stop button SB 1, a first start button SB2 and a coil of a first contactor KM1 in sequence. The normally open contact of the first contactor KM1 is connected with the first start button SB2 in parallel. The second branch is formed by connecting a second stop button SB3, a second start button SB4 and a coil of a second contactor KM2 in sequence. The normally open contact of the second contactor KM2 is connected with the second start button SB4 in parallel. The first branch is connected with a limiting switch in series, and the second branch is connected with the limiting switch in series. According to the interlocking control circuit, the limiting switch is additionally arranged on a balance weight of the chain plate conveyor, a motor power supply of the chain plate conveyor is controlled through the limiting switch, the accident that chain plates of the chain plate conveyor are turned over is avoided, and accordingly the effect of protecting the chain plate conveyor is achieved. The interlocking control circuit of the coal briquette chain plate conveyor has the characteristics of being easy to control, easy to maintain by maintenance staff and low in cost.
Description
Technical field
The present invention relates to moulded coal chain mat machine control technology field, more particularly to a kind of moulded coal chain mat machine
Interlock control circuit.
Background technology
There is two-layer carrier bar in the coal rod drying kiln of moulded coal workshop, every layer of carrier bar two ends roller stretches tight carrier bar
Directly, wherein, there are two big counter weights on every layer of carrier bar both sides on kiln hood, and counter weight is by roller
Tense, and roller is operation, and when coal rod is more on carrier bar, carrier bar tension force is just big, counterweight
Hammer just rises, otherwise then declines.If counter weight rises to a certain extent, carrier bar can be caused
Machine is stuck.Under normal condition, the rotation of two-layer carrier bar does not interfere with each other, and upper strata carrier bar goes to will after head
Down to lower floor's carrier bar, lower floor's carrier bar goes to after head coal rod on carrier bar, by the coal rod of drying down to skin
Band machine is transported.Because moulded coal drying kiln dries coal rod, flue gas in kiln using blowing-out gas fume afterheat
Corrosion is larger, high temperature wear state is in when in addition carrier bar works, if one block of carrier bar is blocked
Track, can finally make flood carrier bar all be drawn bad, so as to affect coal rod yield, in addition in kiln
Narrow space, safeguards extremely inconvenient, and it is time-consuming take a lot of work it is laborious.
The content of the invention
The purpose of the present invention is directed to above-mentioned problem of the prior art, there is provided a kind of moulded coal chain mat machine connection
Lock control circuit, on chain mat machine counter weight limit switch is increased, and by limit switch control is gone
The motor power of chain mat machine, chain mat machine one is out of order, and counter weight rises, limit switch action,
The rapid power-off of chain mat machine, it is to avoid the accident that chain mat machine overturns carrier bar occur, so as to reach protection chain
The effect of trigger.
For achieving the above object, the technical solution used in the present invention is：
A kind of moulded coal chain mat machine interlock control circuit, including tie point and the second branch road, it is described
Tie point is the first stop button SB1, the first start button SB2, first contactor KM1
Coil is sequentially connected, and first contactor KM1 normally opened contact is in parallel with the first start button SB2 even
Connect；Second branch road is the second stop button SB3, the second start button SB4, second connects
Tentaculum KM2 coils are sequentially connected, second contactor KM2 normally opened contact and the second start button
SB4 is connected in parallel；The tie point series connection limit switches, second branch road is in series with
Limit switch.
Further, the tie point is in series with upper limit position switch SQ1 and lower position switch
The normally-closed contact of SQ2.
Further, second branch road is in series with upper limit position switch SQ3 and lower position switch
The normally-closed contact of SQ4.
Further, the tie point is in series with the normally-closed contact of the first thermorelay KH1.
Further, the second branch road series connection first contactor KM1 normally opened contact.
Further, second branch road is in series with the normally-closed contact of the second thermorelay KH2.
Beneficial effects of the present invention：A kind of moulded coal chain mat machine interlock control circuit, matches somebody with somebody in chain mat machine
Increase limit switch on weight, the motor power for controlling chain mat machine, carrier bar are removed by limit switch
Machine one is out of order, and counter weight rises, limit switch action, the rapid power-off of chain mat machine, it is to avoid go out
Existing chain mat machine overturns the accident of carrier bar, so as to reach the effect of protection chain mat machine；With control letter
The characteristics of list, attendant easy to maintain, low cost.
Description of the drawings
Fig. 1 is chain mat machine interlock control circuit electrical schematic diagram of the present invention.
Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that the present invention is realized are easy to
Understand and understand, with reference to being specifically illustrating, the present invention is expanded on further.
When being embodied as, with reference to Fig. 1, a kind of moulded coal chain mat machine interlock control circuit, including the
One branch road and the second branch road, tie point is the first stop button SB1, the first start button
SB2, first contactor KM1 coil are sequentially connected, first contactor KM1 normally opened contact and
One start button SB2 is connected in parallel.Second branch road is the second stop button SB3, the second startup
Button SB4, second contactor KM2 coil are sequentially connected, second contactor KM2 normally opened contact
It is connected in parallel with the second start button SB4.
Increase limit switch on chain mat machine counter weight, go to control chain mat machine by limit switch
Motor power, chain mat machine one is out of order, and counter weight rises, and limit switch action, chain mat machine is fast
Quick-break electricity.Tie point series connection limit switches, the second branch road series connection limit switches.First
Branch road is in series with the normally-closed contact of upper limit position switch SQ1 and lower position switch SQ2.Second branch road
It is in series with the normally-closed contact of upper limit position switch SQ3 and lower position switch SQ4.
In order to carry out overload protection to chain mat machine, in tie point the first hot relay is in series with
The normally-closed contact of device KH1；Second branch road is in series with the normally-closed contact of the second thermorelay KH2.
