Description
技术领域technical field
本发明涉及起重设备技术领域，尤其是一种船用起重机远程液压控制系统。The invention relates to the technical field of lifting equipment, in particular to a remote hydraulic control system for a marine crane.
背景技术Background technique
现有技术中，船用液压起重机中，起重机的各个动作采用机械手柄直接在多路阀上操作控制，该操作虽然简单方便，成本低。但由于多路阀的体积较大不适宜安装在司机室内，对于一些带有司机室的起重机，该操作方式就无法不能满足使用要求。影响液压起重机的正常工作。In the prior art, in marine hydraulic cranes, each movement of the crane is directly operated and controlled by a mechanical handle on a multi-way valve. Although the operation is simple and convenient, the cost is low. However, due to the large volume of the multi-way valve, it is not suitable to be installed in the driver's cab. For some cranes with a driver's cab, this operation method cannot fail to meet the use requirements. Affect the normal work of the hydraulic crane.

作为上述技术方案的进一步改进：As a further improvement of the above technical solution:
还包括手动泵，所述手动泵的输出端与电磁换向阀连接；It also includes a manual pump, the output end of which is connected to the electromagnetic reversing valve;
所述起升装置的回油口通过管路连接有风冷器。The oil return port of the lifting device is connected with an air cooler through a pipeline.
本发明的有益效果如下：The beneficial effects of the present invention are as follows:
本发明结构紧凑、合理，通过远程液压控制手柄与比列多路阀组合的控制方式实现起重机各动作的远程控制操作，该远程液压控制手柄体积小不占用空间，操作简便，该远程控制手柄的控制压力低安全性更可靠。The present invention has a compact and reasonable structure, and realizes the remote control operation of each action of the crane through the control mode of the combination of the remote hydraulic control handle and the proportional multi-way valve. Low control pressure is more reliable for safety.
本发明减小了控制手柄的安装体积，可以将比例多路阀安装在司机室外进行远程控制，节省了司机室内部紧凑的空间。用低压控制操作替代了原先的高压直接操作，安全性提高。The invention reduces the installation volume of the control handle, can install the proportional multi-way valve outside the driver's room for remote control, and saves the compact space inside the driver's cab. The original high-pressure direct operation is replaced by low-pressure control operation, which improves safety.
