A double-clamp function hydraulic piling hammer for excavating machinery

Abstract

The invention relates to a double-clamping function hydraulic pile hammer matched with an excavating machine. According to the double-clamping function hydraulic pile hammer, kinetic energy is provided through the excavating machine, and a hydraulic vibrating device is driven; side clamps and a bottom clamp are adopted to work alternately according to different piling working conditions; a rod piece is clamped through a clamping device so that the rod piece can vibrate together with the hydraulic vibrating device; and by means of vibration, soil on the surface of a driven pile is liquefied, and after the side grinding resistance is reduced, the pile is driven into the ground or pulled out of the ground. The double-clamping function hydraulic pile hammer comprises an excavating machine transitional connection device, a vibration reduction device, the vibrating device and the clamping device, wherein the excavating machine transitional connection device is used for being in transitionalconnection with the excavating machine and conducting rotation and shifting; the vibration reduction device is used for being connected with the transitional connection device and the vibration deviceand reducing the influence of the excavating machine; the vibrating device is connected with the clamping device; and the clamping device is fixed to the vibrating device through side clamping rotating and locating shafts, and the clamping function is achieved through self-adaptive clamping jaws.

Description

technical field [0001] The invention relates to a hydraulic piling hammer with double-clamp function matched with an excavating machine. Specifically, it is a hydraulic vibrating device driven by the kinetic energy provided by the excavating machine, and the soil driven into the surface of the pile is liquefied through vibration and the side friction resistance is reduced. A device that is driven into the ground or pulled out of the ground. Background technique [0002] In the existing hydraulic pile driving equipment, the clamping device of the bottom fixed fixture is usually used to clamp the object to be driven into the ground. The activities are free to connect, and it is difficult to operate during the pile clamping and lifting process, and the verticality of the pile cannot be guaranteed. The height of the pile is greatly restricted by the volume of the auxiliary main engine. Positioning, poor security performance. [0003] In addition, for specific forms of objects ...

Problems solved by technology

[0002] In the existing hydraulic pile pulling equipment, the clamping device of the bottom fixed fixture is usually used to clamp the object to be driven into the ground. The activities are free to connect, it is difficult to operate during the pile clamping and lifting process, and the verticality of the pile cannot be guaranteed. The height of the pile is greatly restricted by the volume of the auxiliary main engine. Positioning, poor safety performance

[0003] In addition, for specific forms of objects that need to be driven into the ground, such as plates, due to their specific shapes, they are usually stacked together before use, which makes it difficult to clamp, and they need to be manually or otherwise stood on their sides during clamping or partially overhead
