The invention relates to the technical field of hydraulic transmission, and discloses a scissor fork type forklift attachment which is characterized in that a two-side road distribution mode of oil pipe transmission is changed into a middle road distribution mode, meanwhile, an oil pipe structure is changed to enable the direction of an oil port to be changed into the upper direction, so that a hydraulic oil pipe is not prone to being damaged due to friction influence, and meanwhile, the structure is simple. The pressure control pipe is sleeved with the three-way connector in a threaded mode, so that after entering the three-way connector, hydraulic oil needs to enter the pressure control pipe firstly, vertically impacts on a cutting-shaped flow guide protrusion of an oil conveying hole and then is input into oil outlets in the two sides of the three-way connector through arc-shaped ports, and the impact force of the hydraulic oil vertically impacts on the bottom of the pressure control pipe firstly; at the moment, impact force borne by the pressure control pipe is transmitted to the vertical pipe perpendicular to the three-way connector through the pressure control pipe, so that the impact force is dispersed through the threaded connection portion of the vertical pipe, and the situation that the impact force is gathered at one position, and consequently the T-shaped corner of the three-way connector is rapidly broken is avoided.

    本申请涉及液压传动技术领域,公开了一种剪叉式叉车属具,通过将油管传动的两侧布路方式,更改为中间布路,同时更改油管结构使其油口方向改为上方,使得液压油管不易受到摩擦影响而发生损坏,同时,通过在三通接头内部螺纹套接控压管,使得液压油进入三通接头后,需要先进入控压管内,并垂直冲击在输油孔的切割形导流凸起上,然后通过弧形端口输入三通接头的两侧出油口,使得液压油的冲击力先垂直冲击在控压管的底部,此时控压管受到的冲击力将通过控压管传递给三通接头垂直的垂直管,使得垂直管通过螺纹连接的部位将冲击力分散,避免冲击力汇聚在一处,导致三通接头T字形拐角处的快速破裂。
