Embodiment 1

[0049] This embodiment provides a crane idling flameout system, the crane idling flameout system uses a controller to control the engine of the crane in the idling state to perform flameout operation.

[0050] see figure 1 The crane idling flameout system is shown in the structural diagram, the crane idling flameout system includes: controller 1, idle flameout mode switching switch 3, hydraulic oil temperature sensor 4, throttle module, actuator 10, start relay 11, flameout relay 12, Engine electronic control unit 7, rotational speed sensor 8 and water temperature sensor 9;

[0051] The above-mentioned controller 1 is respectively connected with the above-mentioned idle stop mode switching switch 3, the above-mentioned hydraulic oil temperature sensor 4, the above-mentioned throttle module, the above-mentioned actuator 10, the above-mentioned starting relay 11, the above-mentioned flame-out relay 12, and the above-mentioned engine electronic control unit 7; The electronic con...

Embodiment 2

[0076] This embodiment provides a crane idling flameout method, which is used in the crane idling flameout system of the above embodiment.

[0077] see figure 2 , a crane idling flameout method, comprising the following specific steps:

[0078] Step 200, when the engine is started, the controller judges whether the idle stop switch is on, if yes, execute step 202, if not, execute step 204.

[0079] Specifically, the above step 200 includes the following steps (1) to (3):

[0080] (1) After the engine is started, the controller sends a switch state acquisition instruction to the idle stop switch, so that the idle stop switch feeds back the current switch state information of the idle stop switch to the controller, and the previous switch state information records the switch state identification;

[0081] (2) Obtain the switch state information fed back by the above-mentioned idle flameout switch;

[0082] (3) Judging whether the switch state identification recorded in the s...

Embodiment 3

[0131] see Figure 4 , this embodiment proposes a crane idling flameout device, which is used in the controller described in the above embodiment; the crane idling flameout device includes:

[0132] Judging module 400, used for judging whether the idle stop switch is on after the engine is started;

[0133] The idle stop module 402 is configured to perform a stop operation on the engine when the engine is in an idle state, so that the engine enters an idle stop state if the judgment result obtained by the judgment module is yes.

[0134] In summary, the crane idling flameout device provided in this embodiment, in the "idling automatic flameout" mode, controls the engine of the crane in the idling state through the controller to perform flameout operation, which can only be manually operated by the crane driver in the prior art Compared with engine flameout, the engine can be turned off in time without manual operation, avoiding fuel consumption and wear caused by long-term id...

Abstract

The invention provides an idling-stop system, method and device for crane. An engine of the crane in an idling state is controlled by a controller to perform a stop operation. Compared with manual operation of stopping the engine by a crane driver in the prior art, the invention has the advantages that the engine can be immediately stopped without manual operation, so that fuel consumption and wear caused by long-term idling of the engine are avoided, and the service life of the engine is prolonged.

Description

technical field [0001] The present invention relates to the technical field of cranes, in particular to a crane idle stop system, method and device. Background technique [0002] A crane refers to a multi-action hoisting machine that vertically lifts and horizontally transports heavy objects within a certain range, also known as a crane. During the use of the crane, it is necessary to frequently start and stop the engine of the crane to operate the crane. [0003] In related technologies, the start and stop of the crane engine are all actively operated by the driver, that is, the driver decides when to start and stop the engine. When the engine is to be started, the driver turns the ignition switch to start the engine when the starting conditions are met; when the engine is to be stopped, the driver first reduces the engine speed to an idle speed, then turns off the ignition switch to shut down the engine. [0004] In the course of realizing the present invention, the inve...
