Auxiliary equipment for self-power-off protection of drilling electromechanical equipment according to building resistance

Abstract

The invention relates to the technical field of electromechanical equipment, and discloses auxiliary equipment for self-power-off protection of drilling electromechanical equipment according to building resistance, the auxiliary equipment comprises a mounting seat, a protection plate is fixedly connected to the top of the mounting seat, a guide rod is fixedly connected to the top of the protection plate, and a supporting rod is fixedly connected to the top of the guide rod; the top of the supporting rod is movably connected with a reset spring, the left side and the right side of the guide rod are both movably connected with electric blocks, and the resistance borne by the mounting base is increased, so that the reset spring is compressed to drive the shunting contact to slide in the limiting cavity along the guide block till the shunting contact makes contact with the electrified contact. When the shunting contact is in contact with the electrifying contact, the circuit is switched on, at the moment, current flows into the electrifying circuit through the electric block and then flows into the shunting resistor through the electrifying circuit, so that the shunting resistor is electrified, and the effects that the rotating speed of the drill bit is automatically reduced and the drill bit is contracted to prevent the drill bit from being broken when the resistance of a hard object is too large in the drilling process are achieved.

Description

technical field [0001] The invention relates to the technical field of electromechanical equipment, in particular to an auxiliary equipment for self-power-off protection according to building resistance for drilling electromechanical equipment. Background technique [0002] Electromechanical equipment generally refers to electrical appliances, machinery, electrical automation equipment, etc. Drilling equipment is a kind of electromechanical equipment. Nowadays, drilling equipment is used in the construction of buildings and the installation of large electromechanical equipment. It has been integrated into the It has become one of the irreplaceable electromechanical devices in people's lives. [0003] The current drilling equipment needs the operator to apply a pressure to the building synchronously during the use process, and because the force is mutual, the drilling equipment at this time will also be subjected to a reaction force, and during the drilling process If you en...

Problems solved by technology

[0003] The current drilling equipment needs the operator to apply a pressure to the building synchronously during the use process, and because the force is mutual, the drilling equipment at this time will also be subjected to a reaction force, and during the drilling process If you encounter extremely solid objects such as steel bars, excessive pressure will easily cause damage to the drilling equipment, ranging from the burning of the drilling motor to the serious injury of the drill bit, and often in the process of drilling. A large amount of dust, which often needs to be cleaned from the hole after the drilling is completed, and the dust scattered in the air during the cleaning process is also a kind of pollution to the environment
