3 results about "Pile driver" patented technology

A vibration generator for a vibration pile driver has imbalance masses that can rotate and which are disposed on shafts. The rotational position of the imbalance masses can be adjusted relative to one another. A control and regulation circuit is provided, which has the following components: a memory unit for storing ground composition data sets or task-specific default data sets with defined operational characteristic variables; sensors for continuous detection of the defined operational characteristic variables; an evaluation unit for comparing the operational characteristic variables that are determined with the operational characteristic variables of the selected default data set; a regulation device for regulating the vibration generator; and a control device for controlling the means for adjusting the rotational position of the imbalance masses relative to one another. The vibration generator is part of a vibration pile driver.

The invention discloses a pile driver. The pile driver comprises a platform, a pile driving device, a walking device and a clamping device. Wherein the piling device is connected to the upper portion of the platform and comprises a piling device used for installing a pile and a pressurizing device connected with the piling device, and the pressurizing device is used for providing vertical acting force for the piling device to pile the pile; the walking device is connected below the platform and used for walking on the ground; the clamping device is connected to the lower portion of the platform and comprises a fixed clamping device, a sliding clamping device and a clamping driving part, the fixed clamping device and the sliding clamping device are both used for clamping the pile wall, the fixed clamping device is fixedly connected to the platform, the sliding clamping device is slidably connected to the platform, and the clamping driving part is connected to the platform. The clamping driving part is connected with the sliding clamping device so as to drive the sliding clamping device to slide along the platform. By applying the pile driver provided by the invention, ground construction and water construction can be realized, the breaches of a polder embankment can be quickly blocked, the life safety of construction rescue personnel is guaranteed, and the life and property loss of people in a flood discharge area is reduced.

The invention provides a pile shoe of a drainage plate pile driver. The pile shoe comprises a pile shoe shell, a fixing pin and a connecting chain. A fixing part is arranged on one side of the pile shoe shell. The fixing pin is clamped in a shoe slot. One end of the connecting chain is connected with the fixing part, and the other end of the connecting chain is fixed to the fixing pin. The upper end of the pile shoe shell is fixed to a pile pipe. A drainage plate back-drawing preventing assembly comprises an arc elastic plate, an eccentric shaft and a compression part. The inner wall of the pile shoe shell is provided with a penetrating slot. The arc elastic plate penetrates through the penetrating slot, the upper end of the arc elastic plate is clamped into the penetrating slot, and the lower end of the arc elastic plate is fixed to the inner wall of the pile shoe shell through a fastener. The compression part compresses the upper end of the arc elastic plate, and the two ends of the compression part are fixed to the inner wall of the pile shoe shell. The eccentric shaft abuts against the inner side of the arc elastic plate, and the two ends of the eccentric shaft are rotationally connected with the pile shoe shell. A plate penetrating groove is formed between the outer side of the arc elastic plate and the inner wall, opposite to the outer side of the arc elastic plate, of the pile shoe shell. By means of the pile shoe, the back-drawing rate is effectively reduced, and working efficiency is improved.
