The invention discloses a novel telescopic cylinder arm pin control system which comprises a cylinder arm pin control valve, a cylinder arm pin control pump, a telescopic oil cylinder, a cylinder arm pin switching valve, a cylinder head body and an emergency ball valve, a P opening in a cylinder arm pin control valve body is connected with an oil outlet of the cylinder arm pin control pump, a T opening in the cylinder arm pin control valve body is connected with an oil tank, and a B opening in the cylinder arm pin control valve body is connected with the emergency ball valve. The other end of the emergency ball valve is respectively connected with an arm pin control oil cylinder and a cylinder pin control oil cylinder in the cylinder head body, a P'port is connected with a core tube on the telescopic oil cylinder, and the other end of the core tube is connected with a P port of an arm pin switching valve; a port A on the valve body of the cylinder arm pin switching valve is connected with a cylinder pin control oil cylinder on the cylinder head body, and a port B is connected with an arm pin control oil cylinder; an electromagnetic proportional overflow valve is arranged in a valve body of the cylinder arm pin control valve, an oil inlet of the electromagnetic proportional overflow valve is communicated with the first oil channel, and an oil outlet of the electromagnetic proportional overflow valve is communicated with the oil return channel. On one hand, the problem that abnormal sound is generated when an arm pin is inserted into an arm pin hole can be solved, meanwhile, the optional multi-configuration optional design of two telescopic systems of a single cylinder bolt and a double-cylinder rope row in the same vehicle type can be achieved, the overall modularization degree is higher, and the research and development cost is reduced.

    本发明公开了一种新型伸缩缸臂销控制系统,包括缸臂销控制阀、缸臂销控制泵、伸缩油缸、缸臂销切换阀、缸头体、应急球阀,缸臂销控制阀阀体上的P口与缸臂销控制泵的出油口连接,T口与油箱连接,B口与应急球阀连接,应急球阀另一端分别与缸头体中的臂销控制油缸与缸销控制油缸连接,P′口与伸缩油缸上的芯管连接,芯管另一端与臂销切换阀的P口连接;缸臂销切换阀阀体上的A口与缸头体上的缸销控制油缸连接,B口与臂销控制油缸连接;缸臂销控制阀的阀体内部设置有电磁比例溢流阀,电磁比例溢流阀的进油口与第一油道相通,出油口与回油油道相通。本发明一方面可以解决臂销插入到臂销孔中产生异响的问题,同时可以实现同一车型下单缸插销和双缸绳排两种伸缩系统的可选多配置选装设计,整体模块化程度更高,降低研发成本。
