Description

Technical Field

[0001] This utility model relates to the field of rolling door motor technology, and more specifically, it relates to a rolling door motor for fireproof rolling shutters. Background Technology

[0002] Fire-resistant roller shutters are roller shutters that, together with their frames, can meet the requirements for fire resistance stability and integrity within a certain period of time. They consist of curtain panels, roller shafts, motors, guide rails, supports, protective covers, and control mechanisms. Fire-resistant roller shutters are mainly used in walls that require fire separation, especially firewalls and fire-resistant partitions where large openings are needed for production or use, but fire doors cannot be installed. Fire-resistant roller shutters are widely used in fire-resistant partition areas of industrial and civil buildings, effectively preventing the spread of fire and protecting life and property. They are an indispensable fire protection facility in modern buildings.

[0003] Most existing fireproof rolling shutter door motors use synchronous belts for transmission. Over time, the synchronous belts inevitably deform, leading to slippage and loosening, which affects the normal operation of the device.

[0004] Furthermore, most existing fireproof rolling shutter door motors are driven by electric motors. When there is a circuit failure or power outage, this type of motor will make it difficult to raise the rolling shutter door, affecting normal use. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a fireproof rolling shutter door motor, which solves the technical problem mentioned in the background art that most existing fireproof rolling shutter door motors are driven by synchronous belts. After long-term use, the synchronous belts inevitably deform, leading to slippage and loosening.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fireproof rolling shutter door motor, comprising a door frame, a transmission housing fixedly provided on the upper end face of the door frame and located on one side, a rotating shaft rotatably provided on the inner wall of the transmission housing and located at the bottom, an adjustment hole provided on the upper end of the rotating shaft and located on the inner wall of the transmission housing, a sliding groove provided on the outer wall of the transmission housing, a sliding block slidably provided inside the sliding groove, a motor provided on the outer wall of the sliding block, the output end of the motor located inside the adjustment hole, a synchronous pulley provided on both the output end of the motor and the rotating shaft, a synchronous belt provided on the two synchronous pulleys, a threaded column fixedly provided on the upper end face of the sliding block, the threaded column being movably installed on the upper end of the transmission housing, an adjusting nut provided on the threaded column, two sets of adjusting nuts being provided and respectively abutting against the upper end of the transmission housing and the inner wall of the sliding groove, an emergency box provided on the upper end face of the door frame and located on the other side, and the other end of the rotating shaft being rotatably installed with the emergency box.

[0007] The present invention is further configured such that a worm gear is rotatably provided inside the emergency box, one end of the worm gear passes through the emergency box and is fixedly provided with a handwheel, a turbine is provided on the outer wall of the rotating shaft and located inside the emergency box, the worm gear and the turbine are meshed and installed, and an oil storage box is provided on the upper end face of the emergency box to facilitate lubrication of the connection position between the turbine and the worm gear.

[0008] The present invention is further configured such that a drip head is provided at the bottom of the oil storage box, and the drip head is located at the top of the worm and turbine, so as to facilitate the lubricating oil to drip onto the top of the turbine and worm.

[0009] The present invention is further configured such that a roller shutter door body is provided on the outer wall of the rotating shaft, and strip blocks are fixed on both sides of the inner wall of the door frame. Two sets of strip blocks are provided on both sides of the roller shutter door body. Each strip block has an installation groove inside, and a roller is rotatably provided inside the installation groove. The rollers are in contact with the outer wall of the roller shutter door body, which facilitates guiding and limiting the roller shutter door body.

[0010] The present invention is further provided with a protective shell at the upper end of the door frame, the protective shell being located at the outer end of the roller shutter door body, which facilitates the protection of the roller shutter door body.

[0011] The present invention is further provided that the upper end face of the oil storage box is provided with an oil injection pipe, and the oil injection pipe is provided with a threaded cap to facilitate the covering of the upper end of the oil storage box.

[0012] The present invention is further provided with guide rods on both sides of the inner wall of the sliding groove, and the sliding block is slidably installed with the guide rods to facilitate guiding the sliding block.

[0013] The present invention is further configured such that a strip-shaped hole is provided on the upper end face of the door frame, and the roller shutter door body is located inside the strip-shaped hole, which facilitates the raising and lowering of the roller shutter door body.

[0014] Compared with the prior art, this utility model provides a fireproof rolling shutter door motor, which has the following beneficial effects:

[0015] By incorporating a transmission housing, adjustment hole, motor, and threaded post, the user can adjust the installation height of the sliding block and motor by rotating the adjustment nut. This allows for easy adjustment of the distance between the two synchronous pulleys based on the length of the synchronous belt, preventing slippage and inability to mesh properly, thus ensuring the normal operation of the device.

[0016] By incorporating an emergency box, worm gear, handwheel, and turbine, in the event of a circuit burnout or power outage, the user can first turn the adjusting nut to loosen the timing belt, then turn the handwheel to cause the worm gear to drive the turbine, which in turn drives the rotating shaft to raise the roller shutter door body, achieving an emergency operation effect and facilitating subsequent maintenance. Furthermore, the user can periodically add lubricating oil to the oil reservoir, which then flows out from the drip nozzle, to lubricate the connection between the worm gear and turbine, ensuring convenient use later.

[0017] By setting up strip blocks, mounting slots, and rollers, the rollers will contact the outer wall of the roller shutter body when it rises or falls, so as to limit and guide the roller shutter body, making it more stable when rising and falling, and convenient for long-term use.
