A kind of rock stratum drilling machine equipment

Abstract

The invention relates to the field of hole-pulling machinery, in particular to a kind of rock-layer hole-pulling machinery equipment, comprising a fixing frame, a base body, a traction device, a rocker arm, a pile hammer, a pile body and a steel sheath, and the fixing frame is fixedly arranged on the On the ground, a base body is fixedly installed on the base body, and the base body is hingedly connected with the rocker arm. The rocker arm is controlled by a hydraulic cylinder during piling, and in the state of leaning on the base body, rotates around the hinge point to 90° with the horizontal plane, The steel sheath is preset in the ground where the pile is to be driven before the pile is driven, and a pile body is arranged inside. The pile hammer is set on the side of the rocker arm through a sliding mechanism. The arm moves in the direction of being flush, the bottom of the pile hammer is sleeved on the pile body, and the pile is driven by the impact core inside the pile body. The impact core is controlled and lifted by the traction device. , and the auxiliary power is provided by the diesel explosion reaction of the pile hammer.

Description

technical field [0001] The invention specifically relates to the technical field of drilling pile machinery, in particular to a mechanical device for drilling a hole pile in rock formations. Background technique [0002] In modern engineering construction, in the production activities such as house construction, bridge laying, and tunnel excavation, it is necessary to drill hole piles to ensure the stability of the building. Therefore, the efficiency of the piling machinery and the quality of the holes directly affect the construction time and length of the building. Quality Standard. [0003] The current drilling machine mainly uses diesel piling machine 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 after falling, the air in the combustion chamber below is squeezed to form a high pressure and high temperature and then pass through. The atomized diesel fuel explodes to form a ...

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
