The invention belongs to the field of hydraulic lifting of commercial vehicle cabs, in particular to an anti-collision lifting device for a front panel of a commercial vehicle cab, which is characterized in that a two-position two-way valve (4) is connected in parallel on a valve rear high-pressure oil pipe (10), and an oil pipe at one end of the two-position two-way valve (4) is communicated with the valve rear high-pressure oil pipe (10) between a two-position four-way reversing valve (11) and a throttle valve (6); the oil pipe at the other end is communicated with the hydraulic oil tank (1); a reversing switch of the two-position two-way valve (4) is in contact with a front panel (15) of a cab of the commercial vehicle, when the front panel (15) is closed, the two-position two-way valve (4) is in an open state, and when the front panel (15) is opened, the two-position two-way valve (4) is in a normally closed state; according to the lifting device, the cab of the commercial vehicle can be lifted only by opening the front panel (15) of the cab of the commercial vehicle, and the design can prevent the front panel (15) of the cab from colliding with a bumper to cause unnecessary loss.

    本发明属于商用车驾驶室液压举升领域,具体为一种商用车驾驶室前面板防撞举升装置,其中阀后高压油管(10)上并联有一个两位两通阀(4),两位两通阀(4)一端的油管与两位四通换向阀(11)和节流阀(6)之间的阀后高压油管(10)连通,另一端的油管与液压油箱(1)连通;所述两位两通阀(4)的换向开关与商用车驾驶室前面板(15)接触,当前面板(15)闭合时,两位两通阀(4)处于开启状态,当前面板(15)打开时,两位两通阀(4)处于常闭状态;本发明首先要打开商用车驾驶室前面板(15)才能实现商用车驾驶室的举升,这种设计可以防止驾驶室前面板(15)与保险杠碰撞,造成不必要的损失。
