Embodiment Construction

[0010] see figure 1 , The elevator with two-color warning and indicator lights is equipped with travel switches J1 and J2 on the folding lifting arm 1 to determine the working state of the elevator.

[0011] see figure 1 , 2 , The names of the parts are as follows: 1-folding lifting arm, LM555CM-555 timer, U1-NOR gate output trigger, Q1-transistor, Q2-transistor, Q3-transistor, D1-diode, D2-diode. In LM555CM: pin 1-power supply VCC, pin 2-reset RST, pin 3-threshold THR, pin 4-trigger TRI, pin 5-ground GND, pin 6-output OUT.

[0012] see figure 2 , the control circuit of the elevator with two-color warning and indicator lights includes two travel switches J1, J2, two indicator lights X1, X2; two travel switches J1, J2 output trigger through NOR gate, transistor Q1 and LM555CM timer The input terminal is connected; one end of the two indicator lights X1 and X2 is connected to the power supply through the triode Q2 and Q3, and the other end is connected to the ground termina...

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 [0001] The invention relates to a lifting device, that is, a lift with two-color warning and index lights. Background technique [0002] In the prior art, the lift adopts a folding lifting arm to realize lifting under the action of an oil cylinder. Under the condition of insufficient light, the lifting height of the elevator does not warn the surrounding people, which cannot meet the safety requirements of the work site and poses a potential threat to personal safety. Contents of the invention [0003] The object of the present invention is to provide a safe and reliable elevator with two-color warning and index lights that can indicate the working state and position of the elevator. [0004] The technical solution of the present invention is: the control circuit of the elevator with two-color warning and index lights includes two travel switches J1, J2, two indicator lights X1, X2; the two travel switches J1, J2 pass through the NOR gate output trigger I...
