Problems solved by technology

[0002] With the rapid development of the underground engineering industry, the ensuing complexity of the rock formation structure, a single hob-type cutter head can no longer meet the construction needs, the new type of impact cutter head combined with impact crushing and rolling crushing is an important tool for underground engineering construction. A new direction is provided. The cutter head with the hob is a cutter head that rolls the rock formation radially at high linear speed, and the impact equipment impacts the rock formation axially. The cutter head rotates fast, the impact frequency of the impact equipment and Slow speed will lead to jamming of impact equipment, impact omission, etc., slow cutterhead speed, high impact frequency and speed of impact equipment will lead to empty strike of impact equipment
Most of the existing technologies separate the impact equipment and the rolling cutter head, and construct by breaking rocks in stages. This method reduces the efficiency of equipment use, increases the number of construction personnel, and affects the progress of construction.

Abstract

The invention discloses a control system and method of an impact type cutter head device. The control system comprises a cutter head detection device, an impact equipment detection device and a control module electrically connected with the cutter head detection device and the impact equipment detection device, wherein the cutter head detection device is used for detecting the rotating speed of acutter head; the impact equipment detection device is used for detecting the impact frequency and the rotating speed of impact equipment; and the control module is used for controlling the impact equipment or the cutter head according to the cutter head rotating speed detected by the cutter head detection device and the impact equipment impact frequency and the impact equipment rotating speed detected by the impact equipment detection device, so as to make the rotating speed of the cutter head to be matched with the impact frequency and the rotating speed of the impact equipment. According tothe control system and method, the rotating speed of the cutter head can be matched with the impact frequency and the rotating speed of the impact equipment so that the construction efficiency can begreatly improved, and the loss rate and the construction risk of the equipment are reduced.
