Embodiment 1

[0049] combine figure 2 , image 3 as well as Figure 4 As shown, the present application is an emergency control device, which is used for the emergency mechanism 104; it includes a driving member 100, a pump body 101, an emergency oil tank 102 and a closed oil tank 103;

[0050] The driving member 100, the pump body 101, the emergency mechanism 104, and the emergency oil tank 102 form an emergency oil circuit 105 through pipelines, and the emergency oil circuit 105 is used to make the emergency mechanism 104 act. , the action described here refers to lowering the emergency response mechanism 104 .

[0051] The driving member 100, the pump body 101 and the closed oil tank 103 form a non-emergency oil circuit 106 through pipelines, and the non-emergency oil circuit 106 is used for the operation of the actuator.

[0052] Specifically, the present application is provided with an emergency oil circuit 105 and the non-emergency oil circuit 106, wherein a pump body 101 and a cl...

Embodiment 2

[0070] The present application also provides an emergency control method based on the above-mentioned emergency control device, including the following steps:

[0071] In case of emergency, connect the second oil suction passage 109 to the first pressure oil passage 107 and the emergency oil tank 102, and connect the third pressure oil passage 111 to the first pressure oil passage 107 and the emergency oil passage 102 respectively. The emergency mechanism 104 connects the third oil return circuit 112 to the first oil return circuit 108 and the emergency mechanism 104 respectively, connects the second oil return circuit 110 to the The first oil return oil circuit 108 and the emergency oil tank 102;

[0072] Open the second shut-off valve 122, empty the air in the second oil suction oil passage 109 and the second oil return oil passage 110, and prevent the pump body 101 from inhaling air;

[0073] Close the second cut-off valve 122, start the driving member 100, the pump body 1...

Abstract

The invention relates to the technical field of engineering machinery, in particular to an emergency control device and a control system. The emergency control device comprises a drive part, a pump body, an oil tank for emergency and a sealed type oil tank, wherein the drive part, the pump body, a mechanism for emergency and the oil tank for emergency define an emergency oil path; and the drive part, the pump body and the sealed type oil tank define an internal oil path of the emergency control device. while the emergency oil path is not started, a performing mechanism automatically operates;while the emergency oil path is started, the sealed type oil tank only achieves oil return back pressure effect, the pump body sucks oil from the oil tank for emergency; and the sealed type oil tank returns to the oil tank for emergency after the mechanism for emergency realizes emergency, so that conversion, between the emergency control device and the oil tank for emergency, of non-isovolemic hydraulic oil is realized. Besides, while the emergency device is started, the performing mechanism automatically operates and works while the pump body is started once a pipeline is not in communication, so that the pump body does not have a suction-air or idle phenomenon, and therefore, the pump body is not burnt.

Description

technical field [0001] The present application relates to the technical field of engineering machinery, in particular to an emergency control device and a control method. Background technique [0002] When the crane system fails, it is necessary to use the emergency power system for rescue, so as to safely release the hoisted load and realize the recovery of the vehicle. Most of the existing ones work in the following ways: [0003] combine figure 1 As shown, the emergency system includes a first oil suction pipeline 113' and a first oil return pipeline 114', one end of the first oil suction pipeline 113' communicates with the oil tank 111', and the other end passes through a joint and the second oil suction pipeline 115' It communicates with the emergency mechanism 112'; one end of the second oil return pipeline 116' communicates with the emergency mechanism 112', and the other end communicates with the oil tank 111' through the joint and the first oil return pipeline 114...
