3results about How to "Reduce maintenance time" patented technology

This disclosure relates to the field of winding machine drum replacement fixture technology. One embodiment of this disclosure provides a winding machine drum replacement fixture, which includes a fixed base, multiple fixing screws on both sides of the fixed base, a V-shaped bracket, a clamping frame, a clamping plate, a clamping mechanism, a connecting frame, and a buffer-type pressing assembly. The V-shaped bracket is installed on the upper side of the fixed base and is used to support the drum. Multiple clamping frames are installed on the inner side of the V-shaped bracket, and the multiple clamping frames are symmetrically arranged. The clamping plate is inserted into the inside of the clamping frame and can move vertically inside the clamping frame. The clamping plate is used to limit the movement of the drum. The clamping mechanism is installed on the outer side of the clamping frame and is used to clamp the clamping plate. The connecting frame is installed on the upper side of the clamping plate and moves synchronously with the clamping plate. The above technical solution is used to solve the technical problem of excessively long maintenance and repair time in the winding area of ​​the prior art.

This application discloses a DC motor simulation detector for detecting air conditioner indoor units. The DC motor simulation detector includes: a voltage detection and light-emitting module, which has a voltage-regulating diode and a light-emitting element connected in series; and an oscillation module connected to the voltage detection and light-emitting module, used to generate a square wave oscillation signal simulating a DC motor. The voltage detection and light-emitting module and the oscillation module are used to connect to the main board of the air conditioner indoor unit to be tested. This application can simulate the square wave pulse signal generated when a DC motor is running normally, which can be used to quickly and accurately detect and determine the faulty components causing the air conditioner indoor unit to not blow air. This facilitates the repair of air conditioner indoor unit faults that do not blow air, reduces repair time, improves repair efficiency, and reduces repair costs.

The invention discloses a speed reduction driving top drive with double-layer shafts and an anti-impact function, which comprises a driving motor assembly, the driving motor assembly is in transmission connection with a reduction gearbox assembly, a top drive lifting system is arranged above the reduction gearbox assembly, the inner part of the reduction gearbox assembly is in transmission connection with a double-layer shaft system, and the inner part of the double-layer shaft system is in transmission connection with the top drive lifting system. The double-layer shaft system comprises an inner shaft and an outer shaft which are mutually independent and rotationally connected, the outer shaft is in transmission connection with the reduction gearbox assembly, and the top of the inner shaft is connected with a slurry circulating assembly; and the bottom of the reduction gearbox assembly is connected with a pipe processor. The main shaft is innovatively improved to be of a double-layer shaft structure, the inner shaft and the outer shaft are independent and rotate, the outer shaft is connected with the reduction gearbox assembly and bears torque and load, the inner shaft is connected with the drilling tool for drilling work, the main shaft can be rapidly disassembled under the condition that large components such as the reduction gearbox are not disassembled, the replacement difficulty of the inner shaft is lowered, and the maintenance time is shortened.
