[0002] At present, the forming equipment used for the piles with branches and / or bearing plates is known, for example, a multi-part support force plate foundation load-bearing pile forming equipment is disclosed in the patent application publication of CN1108720A. The advantage of the equipment is that it can carry out two-way extrusion, but its hydraulic cylinder is only arranged on one side of the bow pressing mechanism, that is, the upper side. It is long and easy to break, so the structural safety is poor. In addition, because the two hydraulic cylinders are integrally formed, that is, they are nested together, which will cause pressure loss of the hydraulic cylinders, that is, their pushing force will decrease. In addition, the equipment's More sealing links

A forming device for piles with branches and / or bearing plates, which includes a branch hole and / or pile bearing plate slot hole shaper arranged on a bracket, the shaper includes a bow pressure extrusion forming mechanism and The hydraulic drive cylinder, the forming mechanism includes a shell, and the two ends of the shell are respectively fixed to the cylinder body of a hydraulic drive cylinder, and the top end of the piston rod in one of the hydraulic drive cylinders is connected to the paired upper bow pressing arm of the bow pressure extrusion forming mechanism. One end is hinged, the other end of the pair of upper bow pressing arms is hinged with one end of the pair of lower bow pressing arms, and the other end of the pair of lower bow pressing arms is hinged with the top end of the piston rod of another hydraulic drive cylinder located at the other end of the housing.
Description
technical field [0001] The present invention relates to construction equipment for concrete piles in civil engineering. Background technique [0002] At present, the forming equipment used for the piles with branches and / or bearing plates is known, for example, a multi-part support force plate foundation load-bearing pile forming equipment is disclosed in the patent application publication of CN1108720A. The advantage of the equipment is that it can carry out two-way extrusion, but its hydraulic cylinder is only arranged on one side of the bow pressing mechanism, that is, the upper side. It is long and easy to break, so the structural safety is poor. In addition, because the two hydraulic cylinders are integrally formed, that is, they are nested together, which will cause pressure loss of the hydraulic cylinders, that is, their pushing force will decrease. In addition, the equipment's There are many sealing links. Contents of the invention [0003] The purpose of the pre...
