Description

Technical Field

[0001] The invention relates to the technical field of rolling shutter doors, in particular to a stopping device for a rolling shutter door motor. Background Art

[0002] In existing rolling door systems, the stopping function of the motor is usually achieved by traditional mechanical brakes or electromagnetic locks. Although these traditional methods can meet the stopping needs to a certain extent, they often have problems such as complex operation, high maintenance costs, and insufficient lubrication leading to increased wear of transmission parts.

[0003] The transmission components of existing rolling door systems, such as transmission gears and transmission chains, often lack effective lubrication measures. Long-term lack of lubrication will lead to increased wear of transmission components, reduced system performance, and even cause failures. Although this problem can be solved by manually applying lubricating oil regularly, manual lubrication is not only cumbersome, but also difficult to ensure uniformity and timeliness of lubrication. Summary of the invention

[0004] In view of the problems existing in the above-mentioned background technology, the present invention aims to propose an innovative solution, namely, a stopping device for a rolling door motor.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a stopping device for a rolling shutter door motor, comprising a rolling shutter door body, a roller, a first motor, a second motor and an oiling brush, the rolling shutter door body being rolled up on the outer surface of the roller, both ends of the roller being fixedly connected to a fixing plate, a mounting plate being arranged above the roller, the first motor being fixedly connected to the bottom of the mounting plate, a driving end of the first motor being fixedly connected to a driving rod, an end of the driving rod away from the first motor and one end of the roller being penetrated and fixedly connected to a transmission gear, the outer surfaces of the two transmission gears being meshed and connected to a transmission chain, the second motor being fixedly connected to the bottom of the mounting plate, and the driving end of the second motor A screw rod is fixedly connected, and the screw rod is threadedly connected to a stop plate, and the stop plate is located on one side of the transmission chain, and the stop plate is fixedly connected to a fixed block near the side wall of the transmission chain, and a movable plate is arranged under the fixed block, and the movable plate contacts the side wall of the stop plate, and the movable plate passes through the transmission chain, and the movable plate is located between two transmission gears, and the two oiling brushes are respectively fixedly connected to the upper and lower surfaces of the movable plate, and the two oiling brushes correspond to the two transmission gears respectively, and two movable rods are fixedly connected to the top of the movable plate, and the movable rod passes through the fixed block, and a connecting spring is sleeved on the outer surface of the movable rod, and the two ends of the connecting spring are respectively fixedly connected to the fixed block and the movable plate.

[0006] Preferably, the blocking plate is located directly below the driving rod.

[0007] Preferably, a limit rod is fixedly connected to the bottom of the mounting plate, the limit rod passes through the blocking plate, and the driving rod is located between the screw rod and the limit rod.

[0008] Preferably, the bottom of the mounting plate is fixedly connected to a fixing rod, the fixing rod is located on the other side of the transmission chain, and the fixing rod is located directly above the movable plate.

[0009] Preferably, an oil storage tank is provided inside the movable plate, the interior of the oil storage tank is filled with lubricating oil, and the two oiling brushes are both connected to the oil storage tank.

[0010] Working principle: When a stopping device of a rolling door motor is used, the driving rod is driven to rotate by the first motor. The transmission gear on the driving rod is connected to the transmission gear on the roller through a transmission chain. When the driving rod rotates, the transmission gear on the roller is driven to rotate through the transmission chain, thereby driving the roller to retract and release the rolling door body. When it is necessary to add lubricating oil to the transmission gear and the transmission chain, the second motor is started. The second motor drives the screw rod to rotate, and under the constraint of the limit rod, the screw rod can ensure that the stopping plate moves smoothly in the vertical direction. When the stopping plate moves up and down, the fixed block on it drives the movable plate to move synchronously through the connecting spring. The oiling brush on the upper surface of the movable plate contacts the upper transmission gear, and the oiling brush on the lower surface contacts the lower transmission gear, thereby evenly applying lubricating oil. The lubricating oil on the transmission gear is transferred to the transmission chain during the contact process between the transmission chain and the transmission gear, thereby realizing the lubrication of the transmission chain. When it is necessary to stop the rolling door body, the second motor is started again to drive the screw rod to drive the stopping plate to move upward. The stop plate contacts the driving rod on the first motor, and prevents the driving rod from continuing to rotate by physical blocking, thereby stopping the rolling door body. During the stopping process, the stop plate drives the movable plate to move upward. When the movable plate contacts the fixed rod, the fixed rod prevents the movable plate from continuing to move upward, preventing the oiling brush from excessively contacting the rotating transmission gear and being damaged. The movable plate is connected to the fixed block on the stop plate by a connecting spring. This design ensures that even if the fixed rod prevents the movement of the movable plate, it will not affect the normal movement of the screw-driven stop plate.

[0011] The present invention provides a stopping device for a rolling door motor, which has the following beneficial effects: 1. By driving the screw rod through the second motor, the blocking plate can be quickly and accurately moved to the predetermined position, contacting and blocking the driving rod of the first motor, thereby effectively preventing the rolling door from opening or closing in an uncontrolled manner, thereby enhancing safety and stability.

[0012] 2. The device integrates a lubrication system, which can automatically and evenly apply lubricating oil through the contact between the oiling brush and the transmission gear and transmission chain, reducing the tediousness and cost of manual lubrication, while extending the service life of the transmission parts and improving the overall performance and reliability of the system.

[0013] 3. The design of the stop plate and the movable plate fully considers the interaction and protection requirements of the moving parts. The contact between the movable plate and the fixed rod during the stop process can prevent the oiling brush from excessive contact with the transmission gear and damage. At the same time, the design of the connecting spring makes the stop plate and the movable plate have a certain buffer and adaptability, avoiding damage or noise caused by hard contact.

[0014] 4. The blocking device of the present invention is driven by a motor, which realizes automatic control and simplifies the operation process. At the same time, the structural design of the device makes the lubrication and blocking functions relatively independent, which is convenient for daily maintenance and troubleshooting, and reduces maintenance costs and time.

The two ends of the connecting spring 17 are fixedly connected to the fixed block 15 and the movable plate 13, respectively.

[0019] The stop plate 12 is located directly below the driving rod 7. This design ensures that the stop plate 12 can directly and effectively contact the driving rod 7 when moving upward, thus achieving a fast and reliable stop function.
