[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] like Figure 1 As shown:

[0029] A rolling door machine with a UPS power supply comprises a mounting plate 1 and a receiving cover shell 2. A winding drum 5 is rotatably connected to the surface of the mounting plate 1.

[0030] In this embodiment: the existing public (announcement) number: CN213418921U discloses a rolling door machine for fireproof rolling shutters; in order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "rolling door machines on the market mostly use brake coils to brake the rolling doors, and the existing brake coils are mostly powered by external power supplies. When the brake coil is in a short circuit or open circuit state after a long time or the coil is in abnormal contact, the rolling door will fall rapidly under its own gravity when it lacks brakes, which can easily cause casualties and property casualties, and lacks an effective emergency brake structure." In combination with use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve this technical problem, a locking component 3 and an adjustment component 4 are added to the application document.

[0031] More specifically:

[0032] like Figure 1-Figure 4 As shown:

[0033] In combination with the above content, the locking assembly 3 includes a large gear 35 fixedly connected to the surface of the winding drum 5 and a small gear 32 rotatably connected to the surface of the mounting plate 1. The surfaces of the small gear 32 and the large gear 35 are meshed and connected with a chain 33. A moving block 37 is symmetrically arranged on one side of the mounting plate 1 surface close to the chain 33. The surface of the moving block 37 is rotatably connected to the limiting gear 36 through a bearing seat, and a tooth plate 39 is arranged inside the moving block 37.

[0034] In this embodiment: when the rolling door machine is in use, the motor 31 can drive the small gear 32 to rotate, and then the small gear 32 drives the large gear 35 to rotate through the chain 33, and then drives the winding drum 5 to rotate, so as to realize the lifting and lowering of the rolling curtain. When the rolling door machine is powered off, the tooth plate 39 will lock the limit gear 36, and then lock the large gear 35 through the chain 33 to prevent the rolling door from falling rapidly under the action of its own gravity.

[0035] Going further:

[0036] like Figure 1-Figure 4 As shown:

[0037] In order to control the limiting position of the limit gear 36 by the tooth plate 39, in an optional embodiment: a sliding groove is opened on the side of the movable block 37 close to the tooth plate 39, and bolt holes 34 are opened at the four corners of the surface of the mounting plate 1; an electromagnet 311 is installed inside the movable block 37, a magnetic block 310 is fixedly connected to the side of the surface of the tooth plate 39 close to the electromagnet 311, and a spring 38 is symmetrically fixedly connected between the tooth plate 39 and the movable block 37; a motor 31 is installed on the side of the interior of the receiving cover 2 close to the pinion 32, and the output end of the motor 31 is fixedly connected to the pinion 32.

[0038] In this embodiment: when the motor 31 is started to lift the curtain piece, the electromagnet 311 is energized to attract the magnetic block 310 to move and squeeze the spring 38 to contract, so that the tooth plate 39 is separated from the limit gear 36, ensuring the normal rotation of the limit gear 36. When the motor 31 is not started or the power supply is stopped, the power supply to the electromagnet 311 will be stopped at the same time, and the attraction of the electromagnet 311 to the magnetic block 310 will be released. The tooth plate 39 is engaged with the limit gear 36 by the elastic force of the spring 38, and the limit gear 36 is locked, and then the large gear 35 is locked through the chain 33 to prevent the rolling door from falling rapidly under the action of its own gravity. The bolts are inserted into the bolt holes 34 to facilitate the fixing of the mounting plate 1.

[0039] It should be noted that the motor 31 and the electromagnet 311 are electrically connected to the external power supply through a wire, and the electromagnet 311 is connected in series with the motor 31 . When the motor 31 is started, the electromagnet 311 can attract the magnetic block 310 to ensure the normal operation of the chain 33 .

[0040] More specifically:

[0041] like Figure 1-Figure 4 As shown:

[0042] In combination with the above content, an adjustment component 4 is provided on the surface of the mounting plate 1, and the adjustment component 4 includes a fixed block 41 fixedly connected to the surface of the mounting plate 1 close to the moving block 37 and a screw 42 screwed inside the fixed block 41, and the screw 42 is rotatably connected to the moving block 37 through a bearing; a moving groove is opened on the side of the fixed block 41 close to the moving block 37, and a handle is fixedly connected to the end of the screw 42 away from the moving block 37.

[0043] In this embodiment: when the tightness of the chain 33 needs to be adjusted, the movable block 37 can be pushed to move by rotating the screw rod 42, thereby pushing the limit gear 36 to engage with the chain 33, and the chain 33 is pushed by the limit gear 36 to adjust the tension of the chain 33, and the limit gear 36 is driven to separate from the chain 33 by reversing the screw rod 42, thereby releasing the limit of the chain 33 by the limit gear 36, and the chain 33 can be disassembled to facilitate the replacement of the chain 33.

[0044] Going further:

[0045] like Figure 1 As shown:

[0046] In order to enable the rolling door machine to work normally during a power outage or emergency, in an optional embodiment: an emergency power supply wiring 53 is installed inside the mounting plate 1, an auxiliary cable drum 51 is installed below the emergency power supply wiring 53, and an emergency power supply line 52 is wound around the surface of the auxiliary cable drum 51.

[0047] In this embodiment: an auxiliary cable reel 51 is provided at the bottom of the mounting plate 1. When the main power supply is interrupted, the emergency power supply connection 53 is connected to the emergency power supply line 52, and the rolling door machine is powered through the emergency power supply line 52 to ensure the normal operation of the rolling door machine and ensure the safe closing or opening of the rolling door machine in the event of a power outage or emergency, thereby reducing the probability of accidents, improving the safety of the workplace, and ensuring the continuity of the machine and the smooth operation of the production line.

[0048] It should be noted that the emergency power supply wiring 53 uses a 4-core 125A connection head to electrically connect to the roller shutter machine body, and the emergency power supply wiring 53 and the emergency power supply line 52 are connected using a 4-core 125A connector set (waterproof plug and waterproof socket).

[0049] It should be noted that: according to the use requirements, the staff can connect the emergency power supply line 52 with a power supply module (voltage: 440V, current 1250A), and use the incoming power supply method to ensure that the device can work normally even when the power is off.

[0050] Working principle: When the rolling door machine is in use, the motor 31 is first started to drive the small gear 32 to rotate. At the same time, the electromagnet 311 is energized to attract the magnetic block 310 to move and squeeze the spring 38 to contract, so that the tooth plate 39 is separated from the limit gear 36 to ensure the normal rotation of the limit gear 36. Then the chain 33 is used to drive the large gear 35 to rotate, and then the winding drum 5 is driven to rotate to realize the lifting and lowering of the rolling curtain. When the motor 31 is not started or the power supply is stopped, the power supply to the electromagnet 311 will be stopped at the same time, and the attraction of the electromagnet 311 to the magnetic block 310 will be released. The tooth plate 39 is engaged with the limit gear 36 by the elastic force of the spring 38, and the limit gear 36 is engaged with the limit gear 36. The chain 33 is locked, and then the large gear 35 is locked by the chain 33 to prevent the rolling door from falling rapidly under its own gravity. The bolt is inserted into the bolt hole 34 to fix the mounting plate 1. When the tightness of the chain 33 needs to be adjusted, the moving block 37 can be pushed to move by rotating the screw rod 42, thereby pushing the limit gear 36 to engage with the chain 33, and the chain 33 is pushed by the limit gear 36 to adjust the tension of the chain 33. The limit gear 36 is driven to separate from the chain 33 by reversing the screw rod 42, and the limit gear 36 on the chain 33 is released, so that the chain 33 can be disassembled and replaced easily.

[0051] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein with equivalents.
