Stall protection device for electrician handheld motor

Abstract

The invention relates to the technical field of electrician equipment, and discloses a stall protection device for an electrician hand-held motor, which comprises a housing, wherein a supporting housing is fixedly connected to the interior of the housing, a semicircular housing is fixedly connected to the interior of the supporting housing, a coil is fixedly connected to the interior of the semicircular housing, an electrorheological fluid is disposed in the semicircular housing, a rotating gear is movably connected to the interior of the semicircular housing, a conductor is fixedly connectedto the exterior of the rotating gear, and a push rod is movably connected to the exterior of the semicircular housing. According to the invention, under the interaction of all structures of the device, the rotating shaft can be decelerated in time when stalling, a driving power supply can be timely controlled by a control center not to drive the rotating shaft to rotate any more, and an operator can be timely informed that the rotating shaft is stalled, so that the life and property safety of the operator is better protected, and the operator is prevented from being accidentally injured due tothe fact that the operator knows nothing about the stalling of the rotating shaft.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a stall protection device for electric hand-held motors. Background technique [0002] Today's electrician operators need to adapt to various working environments, but in some relatively remote areas, sometimes large motors cannot be used due to certain factors. At this time, it is necessary to use a hand-held motor to meet the basic needs. However, if a stall occurs due to external factors, if the motor is not adjusted in time at this time, it will easily cause irreparable impact on the external equipment, and if the motor drives dangerous items such as knives, the Without the operator's knowledge, the stall rotation at this time is extremely likely to cause the operator to be injured. [0003] Therefore, in view of these problems, we need a stall protection device for electrician's hand-held motor to solve. Contents of the invention [0004] (1) Solved technical ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a stall protection device for an electrician's hand-held motor, which can decelerate the rotating shaft until it stops in time when the shaft stalls, and can control the drive power supply through the control center in time to no longer stop when the shaft stalls. The advantage of driving the rotating shaft and notifying the operator that the rotating shaft has stalled in time solves the problem that when the rotating shaft stalls, the speed is too high to easily cause irreparable damage to the external equipment, and when the rotating shaft stalls out of control, it is easy to cause injury to the operator.
