Efficient rock stratum punching pile mechanical equipment

Abstract

The invention relates to the field of punching pile machinery, in particular to rock stratum efficient punching pile mechanical equipment which comprises a fixing frame, a base body, a traction device, a rocker arm, a pile hammer, a pile body and a steel sheath, the fixing frame is fixedly arranged on the ground, the base body is fixedly installed on the fixing frame, the base body is hinged to the rocker arm, and the rocker arm is controlled by a hydraulic cylinder during pile driving. The steel sheath rotates around a hinge point to form an angle of 90 degrees with the horizontal plane from the state of leaning against the base body, the steel sheath is pre-arranged in the ground at the position for piling before piling, a pile body is arranged in the steel sheath, the pile hammer is arranged on the side face of the rocker arm through a sliding mechanism, and the pile hammer is controlled by the sliding mechanism to move in the direction flush with the rocker arm. The bottom of the pile hammer is arranged on the pile body in a sleeving mode, the pile body is impacted through an impact core in the pile hammer to achieve piling, the impact core is controlled by a traction device to be lifted to a preset position and then falls down, and auxiliary power is provided through a diesel burning explosion reaction of the pile hammer.

Description

technical field [0001] The invention specifically relates to the technical field of perforated pile machinery, in particular to a high-efficiency perforated pile mechanical equipment for rock formations. Background technique [0002] In modern engineering construction, in production activities such as house construction, bridge laying and tunnel excavation, perforated piles are required to ensure the stability of the building. Therefore, the efficiency of piling machinery and the quality of holes directly affect the construction time and the quality of the building. Quality Standard. [0003] The current perforated pile machinery mainly uses a diesel pile driver for piling. Its working principle is similar to that of a single-cylinder two-stroke diesel engine. The hammer head is lifted by a spreader, and the air in the combustion chamber below is squeezed after falling to form high pressure and high temperature. The atomized diesel is ignited and exploded to form a strong p...

Problems solved by technology

[0003] The current perforated pile machinery mainly uses a diesel pile driver for piling. Its working principle is similar to that of a single-cylinder two-stroke diesel engine. The hammer head is lifted by a spreader, and the air in the combustion chamber below is squeezed after falling to form high pressure and high temperature. The atomized diesel is ignited and exploded to form a strong pressure for piling, and the hammer head rises. This piling method makes the gravitational potential energy of the hammer head itself meaningless and wastes its energy. The efficiency is not high, and because of its orientation problem , the hammer head tends to deviate during the up and down movement, which makes the pile body eccentric when sinking
