Description

Rolling door rolling mechanism (2)

The present invention relates to a roll door rolling mechanism, and more particularly to a roll door rolling mechanism that is driven by a motor to retract and release a roll door.

The electric rolling door is a building door facility that is very commonly used in Taiwan. Referring to Figure 1, it is a three-dimensional schematic view of a conventional rolling door rolling mechanism. The conventional rolling door mechanism usually fixes a pair of fixing frames 91 above the gate of the building, and a central shaft 92 is placed on the fixing frame. The central shaft 92 does not need to be rotated, so that a U-shaped fastener 921 can be used to press the screw. It is locked on the fixing frame 91. The support frame 91 is further provided with a support rod seat 931 for erecting two support rods 93. The two support rods 93 are disposed on the outer surface of a fixed disc 94. The center of the fixed disc 94 is provided with a hole sleeved on the central shaft. 92, in turn, the two support rods 93 are used to abut against the fixing frame 91, and the fixing plate 94 is thereby fixed. An outer ring gear 941 is disposed on the inner surface of the fixed plate 94, and the outer ring gear 941 is an outer ring gear of the planetary gear set. The center of a rotating disk 95 is provided with a shaft hole sleeved on the central shaft 92, so that it can rotate relative to the central shaft 92. The inner surface of the rotating disk 95 is provided with a motor 951 and the speed reducer 952 can drive a planetary gear 953 to rotate (pattern The conventional configuration is a two-group power mechanism mechanism provided with two sets of motors 951 and a speed reducer 952. The two planetary gears 953 are meshed with the outer ring gear 941, and the fixed disk 94 provided with the outer ring gear 941 is stationary. When the motor 951 is in operation, the rotary disk 95 is rotated, and the outer surface of the rotary disk 95 is locked and fixed to the top end of the roll door 96. Therefore, when the rotary disk 95 is rotated, the roll door 96 is caused to be lowered or retracted. The center of the rotary disk 95 is further provided with a slip ring seat 954. The slip ring seat 954 is provided with a metal ring piece which can be electrically connected to the carbon brush in the fixed plate 94 to transmit electric power to the motor 951.

During the replacement and maintenance, the staff's hand must bypass the removal hole or gap of the rotating disk 95 to access the power mechanism such as the motor 951. It is difficult to work. Usually, most of the mechanisms must be removed to be repaired or replaced, which is extremely inconvenient. .

2. The fixed disk 94 is erected on the support rod base 931 by two support rods 93, and then the support rod base 931 abuts against the fixed frame 91, and resonance is easily generated during operation.
