[0002] Reinforced concrete is a kind of mixed material. When drilling and cutting encounters steel bars, the load current of the motor will increase by 2-3 times. If the feed speed is not lowered in time, the switch will trip, the fuse will be burned, and the motor will be burned in serious cases. , affect the construction progress. Generally, drilling and cutting equipment adopts manual feeding or automatic feeding manual speed regulation. Users often adjust according to experience. Manual adjustment requires personnel to accompany the equipment to provide feeding power at all times, while automatic feeding manual speed regulation Workers need to monitor and adjust the feed speed at all times, which is labor-intensive

Embodiment Construction
[0015] Below in conjunction with embodiment the present invention is described in further detail:
[0016] The invention is a fully automatic control box, which is suitable for automatic feed drilling and cutting equipment powered by a motor. By monitoring the current of the main motor of the drilling and cutting equipment, and then controlling the action of the feed motor, when the current exceeds the set current, the feed action can be stopped, and when the current is lower than the set, continue to move, so as to realize the control of the main motor and equipment. Protect.
[0017] Such as figure 1 with figure 2 As shown, the present invention includes a box body 1 and a leakage protection switch 2, an air switch 3, an ammeter 7, a controller 8, and a selector switch 9 that are located in the box body 1 and fixed on the box body shell, and are fixed in the box body 1 The current sensing switch 11 and the solid state relay 12 are fixed on the input plug 4, the output pl...

The invention discloses a full-automatic control box. The full-automatic control box comprises a box body and an electric control member fixed on a box body housing. Commercial power passes through an earth leakage protection switch QF1 and an ammeter PA, then one path of the commercial power is supplied to a main motor M1 through an air switch QF2, and the other path of the commercial power is supplied to a translation motor M2 and a cutting-in motor M3 respectively through a solid-state relay SSR, a controller KZQ and a selection switch. A current induction switch K1 sleeves a main power supply line, a normally-closed contact of the current induction switch K1 is serially connected in a control loop of the solid-state relay SSR. According to the invention, the earth leakage protection switch serves as a power supply loop main switch, the safety factor of water-jet cutting is increased, the current induction switch and the solid-state relay form a monitoring circuit to monitor the current change of the main circuit and control the translation motor or the cutting-in motor to act. The feeding speed can be automatically adapted to different materials and change automatically, and an operator does not need to monitor and adjust the feeding speed all the time, so that the manual labor intensity is lowered, and the damages to equipment due to untimely reaction of the operator are reduced.
Description
technical field [0001] The invention belongs to the field of control boxes, and in particular relates to a fully automatic control box. Background technique [0002] Reinforced concrete is a kind of mixed material. When drilling and cutting encounters steel bars, the load current of the motor will increase by 2-3 times. If the feed speed is not lowered in time, the switch will trip, the fuse will be burned, and the motor will be burned in serious cases. , affect the construction progress. Generally, drilling and cutting equipment adopts manual feeding or automatic feeding manual speed regulation. Users often adjust according to experience. Manual adjustment requires personnel to accompany the equipment to provide feeding power at all times, while automatic feeding manual speed regulation Workers are required to monitor and adjust the feed rate at all times, which is also labor-intensive. Contents of the invention [0003] The technical problem to be solved by the present ...
