具体实施方式 Detailed ways

下面结合具体实施例对本实用新型进一步加以阐述。Below in conjunction with specific embodiment the utility model is further elaborated.

如图1所示的一种具有安全防护功能的柴油机紧急停车系统，它包括控制装置1、紧急停车电磁阀2停车气缸3，紧急停车电磁阀2的控制端与控制装置1的紧急停车控制端相连；本实施例中，控制装置1具有控制面板11，控制面板11上设有手动控制或远程控制的紧急停车按钮111，该紧急停车按钮111可作为为紧急停车控制端，而控制装置的远程控制箱的控制端与紧急停车按钮111相连，用于远程自动控制紧急停车。As shown in Figure 1, a diesel engine emergency stop system with safety protection function, it includes a control device 1, an emergency stop solenoid valve 2, a parking cylinder 3, the control end of the emergency stop solenoid valve 2 and the emergency stop control end of the control device 1 In this embodiment, the control device 1 has a control panel 11, and the control panel 11 is provided with a manual control or remote control emergency stop button 111. The emergency stop button 111 can be used as an emergency stop control terminal, and the remote control device The control end of the control box is connected with the emergency stop button 111 for remote automatic control of emergency stop.

外部压缩空气经紧急停车电磁阀2后进入停车气缸3，其中，紧急停车电磁阀2受紧急停车按钮111控制，用于控制柴油机紧急停车；停车气缸3为多个，呈并联状分布。The external compressed air enters the parking cylinder 3 through the emergency stop solenoid valve 2, wherein the emergency stop solenoid valve 2 is controlled by the emergency stop button 111, and is used to control the emergency stop of the diesel engine; there are multiple parking cylinders 3, which are distributed in parallel.

紧急停车电磁阀2由两个并联设置的二位三通电磁阀21组成，两二位三通电磁阀21构成或门形式，即，两二位三通电磁阀21的进气口均接入同一外部压缩空气，两二位三通电磁阀21的出气口均接至停车气缸3的进气口，两个二位三通电磁阀21的控制端均与紧急停车控制端相连。The emergency stop solenoid valve 2 is composed of two two-position three-way solenoid valves 21 arranged in parallel. With the same external compressed air, the air outlets of the two two-position three-way solenoid valves 21 are connected to the air inlet of the parking cylinder 3, and the control ends of the two two-position three-way solenoid valves 21 are connected to the emergency stop control end.

在柴油机正常运转时，两二位三通电磁阀21处于闭合状态，此时外部压缩空气不进入停车气缸；当需要紧急停车时，按下紧急停车按钮111或通过控制装置1的远程控制箱远程遥控紧急停车按钮111接通，正常情况下两二位三通电磁阀21均换向变成接通状态，外部压缩空气可经紧急停车电磁阀2进入停车气缸3，使停车气缸3的顶柱顶出，把柴油机的喷油泵油齿打到零供油位置，使柴油机紧急停车(停止运转)；但当按下紧急停车按钮111或通过控制装置1的远程控制箱远程遥控紧急停车按钮111接通后，两二位三通电磁阀21的其中一个无法完成换向工作时，另一个可确保外部压缩空气进入停车气缸3，从而确保柴油机停车，实现安全防护功能。When the diesel engine is running normally, the two-two-position three-way solenoid valve 21 is in a closed state, and the external compressed air does not enter the parking cylinder at this time; when an emergency stop is required, press the emergency stop button 111 or remotely The remote control emergency stop button 111 is turned on. Under normal circumstances, the two two-position three-way solenoid valves 21 are switched to the on state, and the external compressed air can enter the parking cylinder 3 through the emergency stop solenoid valve 2, so that the top column of the parking cylinder 3 Push out, put the fuel injection pump oil teeth of the diesel engine to the zero fuel supply position, and make the diesel engine emergency stop (stop running); but when the emergency stop button 111 is pressed or the remote control box of the control device After passing through, when one of the two two-position three-way solenoid valves 21 cannot complete the reversing work, the other can ensure that the external compressed air enters the parking cylinder 3, thereby ensuring that the diesel engine stops and realizes the safety protection function.

当然，本实用新型并不局限于上述实施方式，熟悉本领域的技术人员在不违背本实用新型精神的前提下还可作出等同变形或替换，这些等同的变型或替换均包含在本申请权利要求所限定的范围。Certainly, the present utility model is not limited to the above-mentioned embodiments, and those skilled in the art can also make equivalent modifications or replacements without violating the spirit of the utility model, and these equivalent modifications or replacements are included in the claims of this application. limited range.
