A leakage circuit breaker is also connected to the first terminal board. The remote control system used for the crane has simple structure and high automation degree, replaces the manual operation in the prior art, and ensures the operation accuracy of the crane.

Description

A kind of hoisting crane command and control system

Technical field

The utility model relates to the telecontrol engineering field, relates in particular to a kind of hoisting crane wireless remote-control system.

Background technology

Hoisting crane of the prior art in lifting work because the structure of hoisting crane self, can there be some dead angles in driver's sight line, in order to address this problem, need to be equipped with a staff and commanders such as the driver is propagandaed directed to communicate or makes a gesture, this mode is difficult to guarantee that the preparation of linking up is errorless, cause operating inaccurate, not in place, and have great potential safety hazard.

The utility model content

The utility model is intended to overcome above the deficiencies in the prior art, and a kind of hoisting crane command and control system is provided.

The utility model technical solution problem adopts following technical scheme:

A kind of hoisting crane command and control system comprises:

Digiplex is used for sending instruction;

Wireless receiver is used to receive the instruction that Digiplex sends;

Internal circuit, described internal circuit comprises first touch block, the four pairs of AC contactor and second touch block, described wireless receiver is connected with four pairs of AC contactor by first touch block, described four pairs of AC contactor respectively by second touch block with move forward and backward motor, bridge motor, steer motor, the corresponding connection of lifting motor.

Further, also be connected with Electrical leakage on described second touch block.

Principle of work of the present utility model is as follows: send action command by corresponding button on the Digiplex to receptor, receptor converts signal to automatically controlled signal after receiving signal, automatically controlled signal is connected corresponding AC contactor by first touch block, AC contactor starts lifting motor, steer motor, front and back movable motor or bridge motor by second touch block, so finish corresponding lifting, turn to, front and back walking or handling work.

The beneficial effects of the utility model are as follows: hoisting crane of the present utility model is simple in structure with command and control system, and the degree of automation height has replaced artificial commander of the prior art, makes that the operation of hoisting crane is precisely errorless.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Figure is labeled as: 1-Digiplex, 2-wireless receiver, 3-first touch block, 4-AC contactor, 5-second touch block, 6-move forward and backward motor, 7-bridge motor, 8-steer motor, 9-lifting motor 10-Electrical leakage.

The specific embodiment

Referring to Fig. 1, a kind of hoisting crane command and control system comprises: Digiplex 1 is used for sending instruction; Wireless receiver 2 is used to receive the instruction that Digiplex 1 sends; Internal circuit, described internal circuit comprises first touch block 3, four pairs of AC contactor 4 and second touchs block 5, wireless receiver 2 is connected with four pairs of AC contactor 4 by first touch block 3, the four pairs of AC contactor 4 respectively by second touch block 5 with move forward and backward motor 6, bridge motor 7, steer motor 8, lifting motor 9 corresponding connections.

Further, also be connected with Electrical leakage 10 on second line connector 5.

The above is preferred embodiment of the present utility model only, is not to be used to limit protection domain of the present utility model.

Claims (2)

1. a hoisting crane command and control system is characterized in that, comprising:
