The invention discloses a pile clamping box support device which is convenient for disassembly and assembly of a pile pressing oil cylinder, which comprises a hanging plate and a cushion block, and the hanging plate is fixedly arranged on one side of a guide column and below the stroke of the pile clamping box driven downward by the pile pressing oil cylinder; The cushion block includes a supporting part for supporting the pile clamping box and a connecting part for connecting with the hanging board, the connecting part is provided with a waist-shaped hole arranged in the vertical direction, the connecting part is connected with the hanging board through a connecting shaft, and The spacer can rotate in the vertical plane with the connecting shaft as the rotating shaft; the present invention can obtain a supporting device with lighter weight, more convenient operation and lower cost through the reasonable design of the hanging plate, the L-shaped spacer and the connecting pin. The invention also discloses a pile driver. When the pile driver is in normal operation, the pile clamping box does not contact the support device, but only when the pile clamping box is disassembled during transportation, maintenance, etc., the pile clamping box contacts the support device. The service life of the supporting device of the pile clamping box is prolonged, and the production cost is effectively reduced.
Description
technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a clamping box support device and a pile driver which facilitate the disassembly and assembly of pile-pressing oil cylinders. Background technique [0002] Hydraulic static pile driver is a pile machine that uses static pressure to press piles into the ground. Hydraulic static pile pressing is a pile pressing method that uses static pressure (the self-weight and counterweight of the pile press machine) to press the prefabricated pile into the soil one by one. This method can save steel bars and concrete, reduce the cost of the project, the concrete strength grade can be reduced by 1 to 2 grades, and the reinforcement can save about 40% of the steel bars than the hammering method, and there is no noise, no vibration, and no pollution during construction. It has little interference to the surrounding environment and is suitable for pile foundation engineering in soft...
