[0016] The utility model provides an embodiment:

[0017] like Figure 1 As shown, a portable mutual control device for a car lifting machine in a maintenance workshop includes a car lifting machine operation indicator light, a one-to-one corresponding controller, a remote control, an electromagnetic relay and a pick operation indicator light, wherein the number of the controller, the remote control, the electromagnetic relay and the pick operation indicator light is consistent with the number of picks to be monitored by the car lifting machine; the controller, the pick operation indicator light and the coil of the electromagnetic relay corresponding to the same pick form a monitoring branch, and the monitoring branches corresponding to different picks are arranged in parallel, and the normally open contacts of all the electromagnetic relays and the car lifting machine operation indicator lights are connected in series to form a control branch, and the control branch is arranged in parallel with the above-mentioned monitoring branch; the monitoring branch and the control branch are connected in parallel at both ends of the power supply.

[0018] The portable mutual control equipment of the car crane outputs 0~220V voltage, which is connected to the voltage-stabilizing resistor and fuse. Through the controller, the pick operation indicator light, the car crane operation indicator light and the relay, it simulates the monitoring situation of the car crane's pick in place. It is used to detect the synchronous lifting of the car crane, so as to judge whether the car crane operation meets the operating conditions.

[0019] In this embodiment, the number of pickaxes to be monitored is 4, and the corresponding controllers are K1, K2, K3, and K4, the electromagnetic relays are ZJ1, ZJ2, ZJ3, and ZJ4, the pickaxe operation indicator lights are L1, L2, L3, and L4, and the locomotive operation indicator light is L5. The pickaxe operation indicator lights L1, L2, L3, and L4 are all red LED lights and are used to indicate the corresponding pickaxes are in place; the locomotive operation indicator light L5 is a green LED light and is used to indicate the synchronous position of all pickaxes.

[0020] The controller has infrared function and learning memory function and can be remotely controlled by a remote controller. The controller and electromagnetic relay are integrated inside a suitcase, and the pickaxe operation indicator light and the crane operation indicator light are integrated on the outer surface of the suitcase.

[0021] The power supply is 220V AC, and the power supply end is connected with a fuse, a voltage-stabilizing resistor, a power indicator light and a power switch, and the power switch is integrated on the outer surface of the suitcase. The voltage-stabilizing resistor is connected in series to the circuit, the fuse and the controller to stabilize the output voltage, which can prevent damage caused by excessively high or low output voltage.

[0022] Working principle: one person is responsible for specific control, and one person has one pickaxe; when the person in control determines that the pickaxe is operating normally, he / she operates the remote control, and the remote control controls the corresponding electromagnetic relay coil to be energized, the pickaxe operation indicator light of the monitoring branch where it is located lights up, and the normally open contact of the corresponding electromagnetic relay on the corresponding control branch closes. When all the normally open contacts of the electromagnetic relays are closed (that is, all the pickaxes are operating normally synchronously), the crane operation indicator light on the control branch lights up, and the crane operation can continue.

[0023] Specific steps:

[0024] 1. Connect to 220V power supply and turn the power switch to "ON";

[0025] 2. According to the operation of the crane, it will be controlled by a dedicated person, with one person using one pickaxe;

[0026] 3. When the four pickaxes of the crane are operating normally and synchronously, operate the remote control, and when the four red lights are on at the same time, the green light will be on; when the green LED light is on, the crane operation can continue.

[0027] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model shall be based on the protection scope of the claims.
