Description

Technical Field

[0001] The present invention relates to the technical field of rolling shutters, and specifically refers to an emergency manual door opening device. Background Art

[0002] Due to advantages such as rapid opening and closing, space saving, safety and reliability, fast rolling shutters are widely used in commercial, industrial, and warehousing places. Traditional fast rolling shutters usually rely on electric control systems for operation, such as variable frequency motors and programmable logic controllers (PLCs). These electric control systems can precisely control the lifting speed, position, and opening and closing time of the rolling shutter, featuring high efficiency and convenience.

[0003] However, traditional fast rolling shutters have significant technical defects in the following situations:

[0004] 1. Power outage or motor failure:

[0005] When a power outage or motor failure occurs, the electric control system cannot work properly, and the rolling shutter cannot be opened in the conventional way. In emergency situations, such as fires and emergencies, this may prevent people from quickly escaping or rescue personnel from entering in a timely manner, posing a serious safety hazard.

[0006] 2. Limitations of backup power supplies:

[0007] To solve the power outage problem, some fast rolling shutters are equipped with backup power supplies, such as batteries or generators. However, backup power supplies have the following problems:

[0008] Long switching time: The switching of backup power supplies takes a certain amount of time, which may result in the inability to supply power in a timely manner in emergency situations.

[0009] Limited coverage: In some scenarios, such as remote areas or places with unstable power supply, backup power supplies may not be able to cover or work properly.

[0010] 3. Risks of manual crank operation:

[0011] To cope with the failure of the electric control system, some fast rolling shutters are equipped with manual cranks. However, manual crank operation has the following problems:

[0012] Risk of working at height: Manual cranks are usually installed at the top or a relatively high position of the rolling shutter, and climbing is required during operation, posing a risk of falling and threatening the personal safety of operators.

[0013] Inconvenient operation: Manual crank operation requires a certain amount of physical strength and time, and may not be able to quickly and effectively open the rolling shutter in emergency situations.

[0014] 4. Destructiveness of violent demolition:

[0015] In extreme cases, such as fires or emergency evacuations, it may be necessary to forcibly break open the rolling shutter door. However, forced breaking will cause deformation or damage to the door body, not only affecting the normal use of the rolling shutter door, but also potentially damaging the building structure and increasing the repair cost.

[0016] Therefore, in the case of the failure of the electric control system of the existing fast rolling shutter door, it mainly relies on the backup power supply or manual rocker operation, and has the following deficiencies:

[0017] Insufficient safety: There is a risk of falling when operating the manual rocker at height, and forced breaking causes damage to the door body.

[0018] Low reliability: The switching time of the backup power supply is long, and it cannot be covered in some scenarios.

[0019] Inconvenient operation: Operating the manual rocker requires time and physical strength and cannot be quickly opened in an emergency.

[0020] Therefore, an emergency manual door opening device is proposed to solve the existing deficiencies. Summary of the Invention

[0021] The technical problem to be solved by the present invention is to overcome the above-mentioned technical defects and provide an emergency manual door opening device.

[0022] To solve the above technical problem, the technical solution provided by the present invention is an emergency manual door opening device, including

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the invention can be understood according to specific situations.

[0050] Combined with the attachedFigures 1-5 As shown in the figure, an emergency manual door opening device can achieve rapid door opening without power support in case of power failure or malfunction. It solves the problem that traditional fast rolling shutters cannot be quickly opened due to their dependence on electric control systems, and at the same time avoids the safety hazards of manual rocker climbing operations and the damage to the door body caused by violent demolition. It truly enables single-person operation to safely, quickly, time-savingly and labor-savingly open the door body, ensuring that people can quickly pass through or escape in case of emergency.

[0051] The emergency manual door opening device includes

[0052] A rolling shutter door main body 1, the rolling shutter door main body 1 includes a frame 11, the frame 11 serves as a support structure for the rolling shutter door main body 1, one end of the frame 11 is provided with a driving motor 12, a rotating frame 13 connected to the driving motor 12 is arranged inside the frame 11, and a rolling shutter door curtain 14 is wound on the surface of the rotating frame;

[0053] Under normal circumstances, the driving motor 12 controls the rotation direction of the rotating frame 13 through forward and reverse rotation, thereby realizing the control of the lifting of the rolling shutter door curtain 14. When it is necessary to close the rolling shutter door curtain 14, the driving motor 12 rotates forward to make the rotating frame 13 rotate, so as to wind the rolling shutter door curtain 14 on the rotating frame 13 to realize the closing of the door body; otherwise, the opening of the rolling shutter door curtain 14 is realized.

[0054] An emergency opening mechanism 2, which applies an opening force to the rolling shutter door curtain 14 in the closed state in case of power failure or malfunction, ensuring that a single person can easily, quickly and safely open the rolling shutter door in an emergency.

[0055] Specifically, the emergency opening mechanism 2 is arranged inside the frame 11 and is connected to the rotating frame 13 for applying an opening force to the rolling shutter door curtain 14 in the closed state;

[0056] Specifically, the emergency opening mechanism 2 is arranged on both sides of the frame 11. Cavities are provided on both sides of the frame 11 to realize the arrangement of the emergency opening mechanism 2, which not only saves space but also ensures the concealment and safety of the emergency opening mechanism 2 during normal operation.

[0057] At the same time, the emergency opening mechanism 2 is symmetrically arranged on both sides of the frame 11, which can effectively prevent the rolling shutter door curtain 14 from being skewed or stuck during the opening process.

[0058] The emergency opening mechanism 2 includes a sling 21 and a spring 22. One end of the sling 21 is connected to the rotating frame 13, and the sling 21 is wound on the rotating frame 13 and is retracted and released as the rotating frame 13 rotates; the other end of the sling 11 is connected to one end of the spring 22 through a connecting buckle 23, and the other end of the spring 22 is connected to the bottom of the frame 11 through a fixed seat 24,

[0059] Under normal circumstances, the sling 21 is wound around the rotating frame 13. As the rolling shutter curtain 14 closes, the rotating frame 13 rotates. At this time, the sling 21 is wound around its surface accordingly, thereby realizing the stretching of the spring 22.

[0060] When emergency opening is required, the braking function of the driving motor 12 is released. At this time, the spring 22 starts to rebound; the resilience of the spring 22 is transmitted to the sling 21 through the connecting buckle 23. The sling 21 is released from the rotating frame 13. After being released, the sling 21 is no longer wound around the rotating frame 13, but is pulled by the elasticity of the spring 22, driving the rotating frame 13 to rotate reversely, thereby realizing the opening of the rolling shutter curtain 14.

[0061] In this embodiment, the sling 21 and the spring 22 are linearly arranged along the height direction of the frame 11. The linear arrangement ensures that the resilience of the spring 22 can be directly and effectively transmitted to the rotating frame 13, reducing the loss and deviation of force, and improving the structural stability of the emergency opening mechanism 2, ensuring that there will be no loosening or jamming during the emergency opening process, making the entire opening process smoother and more stable, and improving the safety and reliability of the operation.

[0062] A guide wheel 25 cooperating with the sling 21 is provided at the upper part of the frame 11 to ensure the stability of the sling 21 during movement. By providing a stable guiding path through the guide wheel 25, it is ensured that the sling 21 always moves in the correct direction, reducing the vibration and swaying during the movement of the sling 21, and improving the operation stability of the entire device.

[0063] Furthermore, a guide cylinder 26 is further included. The guide cylinder 26 is sleeved on the spring 22 and fixedly connected to the frame 11. The setting of the guide cylinder 26 can prevent the spring from shifting and improve the operation stability.

[0064] During the emergency opening process, the spring 22 will quickly rebound and release the stored elastic potential energy. If the spring 22 shifts during the rebounding process, it may cause uneven force transmission or even jamming, affecting the normal opening of the rolling shutter. By restricting the lateral movement of the spring 22 through the guide cylinder 26, it is ensured that it can only move along the axial direction, thereby preventing the occurrence of the shifting phenomenon.

[0065] During the use process, the guide cylinder 26 prevents the spring 22 from shifting, improving the reliability of the entire emergency opening mechanism 2 and ensuring its normal operation in case of emergency. At the same time, the protection of the guide cylinder 26 can reduce the wear and fatigue of the spring 22 and extend its service life.

[0066] In the initial state, the rolling shutter curtain 14 is in the closed state, the sling 21 is wound around the rotating frame 13, and the spring 22 is in the stretched state.

[0067] In specific implementation,

[0068] Normal state:

[0069] The rolling door curtain 14 is in a closed state, at which time the spring 22 is in a stretched state, storing elastic potential energy, and the drive motor 12 controls the lifting and lowering of the rolling door through the rotating frame 13. At this time, the stretching force of the spring 22 is balanced by the braking function of the drive motor 12, keeping the rolling door curtain 14 stationary.

[0070] Emergency opening status:

[0071] 1) When a power outage or failure occurs, the drive motor 12 cannot work and the rolling door curtain 14 cannot be opened in a conventional manner.

[0072] 2) By manually operating the inner door releaser 31 or the outer door releaser 32, the braking function of the drive motor 12 is released. At this time, the tensile force of the spring 22 is released, and the spring 22 rebounds, driving the sling 21 to be released from the rotating frame 13, thereby driving the reverse rotation of the rotating frame 13, so that the rolling door curtain 14 is rolled up, and the rolling door curtain 14 is quickly opened.

[0073] 3) The guide wheel 25 and the guide cylinder 26 respectively constrain the movement trajectory of the sling 21 and the spring 22 to prevent deviation or stagnation, thereby ensuring a smooth opening process. The sleeve of the guide cylinder 26 further improves the stability of the spring 22.

[0074] The manual releaser 3 is arranged on the wall 4 , and the manual releaser 3 is connected to the driving motor 12 . Specifically, the manual releaser 3 is linked to the braking system of the driving motor 12 .

[0075] Specifically, the manual release 3 includes an inner door release 31 and an outer door release 32 , and both the inner door release 31 and the outer door release 32 are connected to the drive motor 12 , and the brake function of the drive motor 12 is released through manual operation.

[0076] Specifically, the inner door releaser 31 is installed inside the door, and the outer door releaser 32 is installed outside the door, and is used to manually release the braking function of the drive motor 12. Operating any releaser can release the braking effect of the drive motor 12 and trigger the spring 22 to release.

[0077] When implementing:

[0078] Under normal circumstances, the braking function of the driving motor 12 keeps the rolling door curtain 14 in a stationary state. When emergency opening is required, the braking function of the driving motor 12 is released by manually operating the in-door releaser 31 or the out-door releaser 32, so that the emergency opening mechanism 2 can work smoothly.

[0079] When the present invention is specifically implemented, in case of an emergency such as a power outage or a malfunction, first operate the manual releaser 3, and manually operate it through the in-door releaser 31 or the out-door releaser 32 to release the braking function of the driving motor 12.

[0080] At this time, since the spring 22 is pre-stretched and stores elastic potential energy, after the driving motor 12 loses its braking, the elastic force of the spring 22 acts on the rotating frame 13 through the sling 21, providing rotational power for the rotating frame 13 and causing the rotating frame 13 to start rotating. As the rotating frame 13 rotates, the rolling door curtain 14 wound around its surface rolls up upward to achieve the opening of the door body. The guide wheel 25 and the guide cylinder 26 respectively play the roles of guiding the movement direction of the sling 21 and stabilizing the movement of the spring 22, ensuring that the entire opening process is smooth and unobstructed.

[0081] When specifically implemented, a torsion spring can also be used to replace the spring, and in cooperation with a drive shaft connected to the rotating frame, it is arranged at the upper end of the frame. The release force of the torsion spring is used to drive the drive shaft to drive the rotating frame to rotate reversely, thereby realizing the rapid and safe opening of the rolling door without electricity in case of a power outage or a malfunction.

[0082] The above describes the present invention and its implementation manners. Such a description is not restrictive, and what is shown in the drawings is only one of the implementation manners of the present invention. The actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the present invention, design similar structural modes and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
