The invention discloses an automatic retractable hydraulic pushing device, which belongs to the field of hydraulic equipment and comprises a base, a hydraulic push rod is mounted at the upper end of the base, and a pushing head is movably connected to one end, away from the base, of the hydraulic push rod. According to the invention, when the extension stroke of the hydraulic push rod reaches the maximum, the hydraulic push rod is shrunk, when the hydraulic push rod is shrunk, the base and the pushing head are subjected to a force which is close to each other, the pushing head tightly grabs the ground through the ground gripping nails when the pushing head is subjected to the force towards the base, and the ground gripping nails are pulled out when the base is subjected to the force towards the pushing head. After the ground gripping nails at the lower end of the base are pulled out, the base is pulled towards the pushing head, then the base is made to be close to the pushing head, when the hydraulic push rod shrinks to the shortest length, the hydraulic push rod stretches, the ground gripping nails at the lower end of the base grip the ground, the pushing head is made to be away from the base, and therefore the moving frame continues to be pushed. And the moving frame can be continuously pushed by repeating the steps, so that the belt conveyor can be continuously pushed.

    本发明公开了一种自动收缩式液压推移装置,属于液压设备领域,包括底座,所述底座的上端安装有液压推杆,所述液压推杆远离底座的一端活动连接有推动头。本发明,当液压推杆的伸展行程达到最大后在使液压推杆收缩,液压推杆收缩时会使底座和推动头受到相互靠近的力,推动头受到向底座方向的力时会通过抓地钉紧紧的抓住地面,而底座受到向推动头方向的力时会将抓地钉拔出,随着底座下端的抓地钉被拔出后,底座便会被向推动头的方向拉动,进而使底座靠近推动头,当液压推杆收缩到最短后在使液压推杆伸展,使得底座下端的抓地钉抓住地面,使推动头向底座的方向远离,从而继续推动移动架,如此反复即可持续的推动移动架,进而可对皮带机进行持续推动。
