A kind of water jet cutting equipment with magnetic reinforcement for mining

Abstract

The invention discloses mining magnetic reinforcing type anchor removing water jet cutting equipment. The equipment comprises a single hydraulic prop, an abrasive jet launching device and an anchor removing device, wherein the anchor removing device comprises an annular cylinder base and a magnetic force starting and stopping thread rod; the right side of the annular cylinder base is provided with an automatic regulation and control device which comprises a spray head stair base, a fixed base, a transmission worm and a spring energy accumulator, the upper end of the spray head stair base is provided with a spray head jacket which is obliquely arranged, the left side of the annular cylinder base is provided with a left-leaning notch, the right side of the annular cylinder base is provided with a right-leaning notch, and the axis of the left-leaning notch, the axis of the right-leaning notch and the axis of the spray head jacket are located on the same straight line. According to the equipment, the cutting angle of a cutting spray head can be automatically regulated, the position of the cutting spray head can be automatically changed, the target distance between a nozzle at the end of the cutting spray head and an anchor rod is effectively guaranteed, and the condition that the annular cylinder base is damaged to be failed due to the fact that water directly cuts the interior of the annular cylinder base is avoided.

Description

technical field [0001] The invention relates to the technical field of abrasive water jet mechanical equipment design, in particular to a mine-used magnetic force reinforced anchor withdrawal water jet cutting equipment. Background technique [0002] The water jet is a high-speed water stream of different shapes formed by the nozzle, and the flow rate of the jet depends on the pressure drop before and after the nozzle outlet section. Water jetting is the simplest form of energy transformation and application. Usually, the power-driven pump completes a suction and discharge process of water, pumps a certain amount of water to the high-pressure pipeline, and makes it reach the nozzle with a certain amount of energy. The hole diameter of the nozzle is required to be much smaller than that of the high-pressure pipeline, so this certain amount of water reaching the nozzle must be accelerated if it wants to flow out of the nozzle hole. In this way, the water that accelerates con...

Problems solved by technology

However, the existing water-jet cutting equipment for mine anchor removal cannot automatically adjust the cutting angle of the cutting nozzle and automatically change the position of the cutting nozzle. It cannot be continuously fixed manually, and the fixing effect of the clamping part of the bolt cutting device is poor. Avoid water directly cutting the inside of the annular cylinder seat and cause premature damage to the annular cylinder seat, which will affect the service life of the equipment
