Abstract
The invention relates to a lifting device, in particular to a lift with dual-color warning indicator lamps. A control circuit of the lift comprises a travel switch J1, a travel switch J2, the indicator lamp X1 and the indicator lamp X2. The travel switch J1 and the travel switch J2 are connected with the input end of an LM555CM timer through a nor gate output trigger. One end of the indicator lamp X1 and one end of the indicator lamp X2 are connected with a power supply through a triode Q2 and a triode Q3, and the other end of the indicator lamp X1 and the other end of the indicator lamp X2 are connected with a grounding end. The travel switch J1 is connected with the triode Q3. The working state of the lift is indicated in the ascending and descending processes in a dual-color warning mode, the red color is displayed for warning and clearance after the working state is stabilized at a high point, and therefore use is safer and more reliable. The lift has the advantages that the circuit is reasonable, simple and practical.
Description
Technical field
The present invention relates to a kind of jacking equipment, with the elevator of double-colored warning, beacon lamp.
Background technology
In the prior art, elevator adopts folding liftable arm, under oil cylinder effect, realizes lifting.Under insufficient light condition, the adjustable height of elevator, to not warning of people around, can not meet work-site safety requirements, and personal safety is caused to potential threat.
Summary of the invention
The object of the invention is provides a kind of mode of operation, position that can indicate elevator, the safe and reliable elevator with double-colored warning, beacon lamp for above-mentioned deficiency.
Technical solution of the present invention is: the control circuit with the elevator of double-colored warning, beacon lamp comprises two travel switch J1, J2, two indicator lamp X1, X2; Two travel switch J1, J2 are connected with LM555CM timer input end by joint denial gate output trigger; Two indicator lamp X1, X2 one end are connected with power supply by aerotron Q2, Q3, and the other end is connected with ground terminal; Travel switch J1 is connected with aerotron Q3.
With the elevator of double-colored warning, beacon lamp, two switches are set on the hold-down arm of elevator, by light current (12 volts of voltages) circuit, mode of operation is acted on two pieces of bulbs and usings bi-colour light form as warning indication; By the state of lamp, the mode of operation that color can be found out elevator.
Advantage of the present invention is: 1, realize and in the process of ascending, descending, with the form of double-colored warning, indicate the mode of operation of elevator, and with redness, play warning, show wide effect after being stable at high point, use more safe and reliable.2, circuit is reasonable, simple, applicable.
Below in conjunction with accompanying drawing, embodiments of the present invention are described in further detail.
Accompanying drawing explanation
Fig. 1 is structure diagram of the present invention.
Fig. 2 is control circuit schematic circuit diagram of the present invention.
The specific embodiment
Referring to Fig. 1, with the elevator of double-colored warning, beacon lamp, be that travel switch J1, J2 are set on folding liftable arm 1, to determine elevator mode of operation of living in.
Referring to Fig. 1,2, parts title is as follows: 1-folding liftable arm, LM555CM-555 timer, U1-joint denial gate output trigger, Q1-aerotron, Q2-aerotron, Q3-aerotron, D1-diode, D2-diode.In LM555CM: pin 1-power supply VCC, pin 2-reset RST, pin 3-threshold value THR, pin 4-triggers TRI, pin 5-ground connection GND, pin 6-exports OUT.
Referring to Fig. 2, with the control circuit of the elevator of double-colored warning, beacon lamp, comprise two travel switch J1, J2, two indicator lamp X1, X2; Two travel switch J1, J2 are connected with LM555CM timer input end by joint denial gate output trigger, aerotron Q1; Two indicator lamp X1, X2 one end are connected with power supply by aerotron Q2, Q3, and the other end is connected with ground terminal; Travel switch J1 is connected with aerotron Q3.
When lifting is during in process of rising or falling, switch J1, J2 all open (shown in Fig. 2), by joint denial gate, export energizing signal, aerotron Q1 conducting, now power supply can be powered to LM555CM timer, thereby make LM555CM timer send pulse to the circuit interruption conducting of aerotron Q2, two bulbs of Q3, two indicator lamp X1, X2 have had the effect of flicker, and warning is when lifting is in process of rising or falling.
When elevator outreaches, switch J1 is closed, and switch J2 opens, and aerotron Q3 obtains incoming signal and conducting, only makes beauty's indicator lamp X2 long bright, and warning lifting is in top.
When elevator is at lowermost end, switch J1 opens, and switch J2 is closed, and aerotron Q1, Q2, Q3 all do not obtain energizing signal that can conducting, thereby two indicator lamp X1, X2 are long, go out.
Describing above, is the specific embodiment of the present invention, and various casehistorys are not construed as limiting flesh and blood of the present invention.
