Self-adaptive intelligent hydraulic and pneumatic impact breaking hammer

Abstract

The invention discloses a self-adaptive intelligent hydraulic and pneumatic impact breaking hammer. The self-adaptive intelligent hydraulic and pneumatic impact breaking hammer comprises a drill rod, a drill rod reciprocating guiding centering mechanism, a piston reciprocating mechanism, an airtight nitrogen volume changing mechanism, an optical grating position sensor, an optical grating signal processing device and a servo driving system. The optical grating position sensor is composed of a movable ruler and two fixed rulers, the movable ruler is installed on the drill rod and reciprocates synchronously along with the drill rod, the two fixed rulers are fixed to a guiding sleeve of the drill rod reciprocating guiding centering mechanism in the feeding direction of the drill rod, the fixed ruler A is located above the fixed ruler B, the fixed ruler A is used for detecting the time of passing through a detecting point of the fixed ruler A of the movable ruler in feeding and bouncing, and controlling the hitting speed and frequency of the drill rod, and a detecting point of the fixed ruler B is used for detecting the feeding limit position of the drill rod. The optical grating position sensor is connected with the optical grating signal processing device. The optical grating signal processing device is connected with the servo driving system which enables the drill rod to change the frequency and speed of hitting an object in a self-adaptive mode according to the hardness of the hit object. According to the self-adaptive intelligent hydraulic and pneumatic impact breaking hammer, the tool use efficiency is improved.

Description

technical field [0001] The invention relates to an intelligent construction machine, in particular to an adaptive intelligent hydraulic-pneumatic impact breaker. A breaking hammer with a certain adaptive ability can output different striking energy and frequency according to the hardness of the object being broken. Background technique [0002] The function of the breaking hammer is to quickly change a large or solid object into a small object that can be moved. The construction of roads, bridges, and high-speed railways is the basic project of national construction. It is often necessary to dismantle reinforced concrete buildings during engineering construction. When maintaining expressways, it is necessary to remove the original cement and mixed asphalt pavement. During the construction of high-speed railways, mountains and rivers must be encountered. For bridge building, a breaker is an essential construction tool. Breaking hammers are generally installed on engineering...

AI Technical Summary

Problems solved by technology

The change of the hitting speed and frequency of the traditional breaking hammer must be manually operated. The hardness of the hit object can only be judged empirically through the appearance observation and the hitting sound. The appropriate strike speed and frequency can only be selected after manual operation, resulting in low work efficiency and waste of energy
