The invention discloses a supporting layer jacking device. The supporting layer jacking device comprises a base, one end of a first lifting rod and one end of a second lifting rod are hinged to the base, the first lifting rod and the second lifting rod are symmetrically arranged along the center line of the base, one end of a first driving rod is hinged to the other end of the first lifting rod, one end of a second driving rod is hinged to the other end of the second lifting rod, the other end of the first driving rod and the other end of the second driving rod are hinged to a top plate, and the top plate is parallel to the base. According to the supporting layer jacking device, the contact face of the jacking device is increased through cooperation of the base and the top plate, and meanwhile the stability of the jacking device in the ascending process is improved through cooperation of the first lifting rod, the second lifting rod, the first driving rod and the second driving rod. A positioning assembly and a limiting rod are matched to reduce the phenomenon of secondary damage in the jacking and reinforcing process due to falling back after jacking, meanwhile, a blocking assembly reduces the phenomenon of falling back after jacking again, and the stability in the reinforcing process is improved.

    本发明一种持力层顶升装置,包括:底座,底座铰接有第一升降杆以及第二升降杆的一端,第一升降杆与第二升降杆沿底座中心线对称设置,第一升降杆另一端铰接有一第一驱动杆的一端,第二升降杆另一点铰接有一第二驱动杆的一端,第一驱动杆以及第二驱动杆的另一端均与一顶板铰接,顶板平行于所述底座设置。通过底座与顶板配合加大顶升装置的接触面,同时通过第一升降杆、第二升降杆、第一驱动杆以及第二驱动杆配合,提高顶升装置上行过程中的稳定性。定位组件与限位杆配合减小顶升后出现回落导致,导致顶升加固过程中出现二次破坏的现象,同时阻位组件再次减小顶升后出现回落的现象,提高加固过程中的稳定性。
