TH613A3 - Motor rotation assistant When there is an error - Google Patents

Abstract

When the motor has a failure Will cause the motor to rotate Freezes and stays put But when there are assistive devices Rotate this motor Can be used normally But must be used in conjunction with the trigger Which this device helps to rotate the motor set Must be used in conjunction with a device called a trigger. Because this trigger will It can only be used when the trigger axis is inserted into the motor-drive assist. And when the trigger is inserted Turn it into the slot and push the trigger slightly forward to free it from the groove. Then it can be performed Rotate the motor rotor axis normally. It is controlled by human rotation force, for example electric motor-controlled patient bed.

Claims (2)

1.This motor rotation aid device It consists of pipes (1) intended for connecting the rotor axis of the The motor on the A side, where the end of the tube (1) has holes (2) on both sides, to attach the motor rotor axis to the tube (1) together by means of a nut or screw to fix it. And the other end of the pipe (1) is connected to a plastic piece (16) that has been machined into shape and angle. Which can turn around Or called Universal Joint (Universal Joint) and fastened by pins (17). The other side of the plastic (16) was fixed by the pipe end (3) by using pins (15). same Then the end of the pipe (3) where the pipe has been reduced. Size down and then inserted into the larger tube (14), where inside the tube (14) is composed of bearings (4) that provide smooth rotation and a plastic (5) that helps to provide Tube (3) that is inserted Spinning in place And at the end of the pipe (3), when it leaves the pipe (14), it is inserted into the pipe (13) and secured with a nut or screw (6), and the end of the pipe (13) has a pipe (8). The smaller one is also inserted and is secured with a nut or screw (7) so that the pipe (8) and the pipe (13) are bolted together. And inside the tube (8), another smaller tube (9) is inserted. But will be driven by a spring (12) to the right (B) principle of operation of this device. That is, when the trigger axis is pushed in to the left (B) to the end of the trigger axis, the pipe (9), which is pushed by the spring (12), moves forward. And will push the steel pin (11) away from the groove of the plastic (10). The trigger can then be rotated and the motor rotor axis rotation can be controlled as needed. 2. Motor rotation equipment according to item 1 can increase / decrease the number of pipes.
