Embodiment Construction

[0011] The on-line control hydraulic drilling anti-seize method described in the embodiment of the present invention, its main steps include:

[0012] ⑴First, arrange the anti-jamming circuit, which consists of impactor, propulsion motor and rotary motor. The oil circuit of the impactor is connected to a propulsion pump, and the external connection of the propulsion motor and rotary motor is connected to the online monitoring device;

[0013] ⑵This online monitoring device is connected with a remote computer to perform online testing and monitor the propulsion pressure or speed. The drill bit cuts into the cave;

[0014] (3) The remote computer tests and monitors the rotary pressure online through the sensor, and when it exceeds the normal value, adjusts the rotary pressure to gradually increase the signal to control the pressure to drop steplessly;

[0015] ⑷For the stuck drill in the crack, control the computer to automatically prevent the rock drilling process.

Abstract

The invention discloses a method for controlling anti-blocking of hydraulic drilling on line. The method comprises the following steps of: firstly, arranging an anti-blocking circuit comprising an impactor, a propulsion motor and a rotary motor; connecting a propulsion pump with an oil-way of the impactor, and connecting an online monitoring device at the outer parts of the propulsion motor and the rotary motor; connecting the online monitoring device with a remote computer to perform online test and monitor propulsion pressure or speed, and mounting a sensor capable of detecting sudden reduction of the propulsion pressure or sudden increment of the propulsion speed onto the online monitoring device to determine that a drill bit drills into a cave; and performing online test and monitoring on rotary pressure through the sensor by the remote computer, and adjusting a gradually-increasing signal of the rotary pressure to control stepless reduction of the pressure when the rotary pressure exceeds a normal value. The method provided by the invention has the beneficial effects that the blocking problem in the drilling is solved, normal drilling operation of a rock drill is ensured, the production efficiency is improved, movement accuracy of the rock drill is improved, the wear degree of the rock drill is reduced, the service life of the rock drill is prolonged, the stress of the body of the rock drill can be assisted, and the like.

Description

technical field [0001] The invention relates to the field of hydraulic technology, in particular to an online control hydraulic drilling anti-jamming method. Background technique [0002] The hydraulic system has the advantages of large power, good adjustability of working pressure and flow, and heat can be brought back to the oil tank. The hydraulic system device can generate more power than other devices. Under the same power, the hydraulic device is small in size, Light weight, high power density, compact structure. The down-the-hole drilling rig is a kind of engineering machinery for drilling minerals and rocks. It is a device in which the impactor dives into the hole and directly impacts the drill bit, and the rotary mechanism drives the drill pipe to rotate outside the hole to drill into the rock. It is mainly used for open-pit mining, Rock drilling in various projects such as building foundations, water conservancy, power stations, building materials, transportation,...
