Truss-like hydraulic lifting apparatus with plugs

A truss-like hydraulic lifting apparatus with plugs, comprising:

• a pile reinforcing frame;
• a truss structure extending through and mounted within the pile reinforcing frame, wherein the truss structure comprises a first number of uniformly disposed support legs, and each of the support legs is provided with a support leg inserting hole;
• a first number of power source devices each provided with a plug corresponding to a support leg inserting hole of each of the support legs;
• a detachable mechanism for detachably fixing each of the power source devices to the pile reinforcing frame,
• wherein the detachable mechanism comprises:
• a base plate which is laterally fixed relative to the pile reinforcing frame, is provided with an opening through which the support leg vertically passes, and forms a protective cap above the power source device, wherein the lateral dimension of the protective cap is larger than the lateral dimension of the power source device, and
• a) wherein in an option A, the base plate is detachably mounted on the pile reinforcing frame via a plug structure, with a mounting plug hole being arranged on the base plate, and the pile reinforcing frame is provided with a mounting plug corresponding to the mounting plug hole;
• or
• b) wherein in an option B, the base plate is detachably mounted on the pile reinforcing frame via a tenon-mortise structure in which a tenon is provided on each of two ends of the base plate connected with the pile reinforcing frame.
