Description

Technical Field

[0001] The utility model relates to the field of security, in particular to a special rolling shutter door deceleration brake system for silver pavilions and a special rolling shutter door for banks. Background Art

[0002] Rolling shutter doors are made of multi-jointed door panels connected in series. The doors rotate up and down around the scroll above the door in a fixed slide. Rolling shutter doors are commonly used in shops, supermarkets, shopping malls, banks and other occasions.

[0003] Among them, rolling shutters are also needed in silver kiosks. Due to the particularity of silver kiosks, they have higher requirements for security, and their strength requirements are higher than ordinary rolling shutters. However, its overall structure is not much different from conventional rolling shutters. In the silver kiosk, if some special circumstances occur, the rolling shutters will be quickly released to quickly close the silver kiosk. Among them, in order to realize the retraction and extension of the rolling shutters, a motor is used to drive the retraction and extension of the rolling shutters. Since the rolling shutters are heavy, a combination of motors and reducers will be used. This structure cannot achieve the rapid descent of the rolling shutters. It is considered that when unwinding, the motor and reducer will be separated from the roller of the rolling shutters, so that the rolling shutters can be quickly released. However, this method can achieve the rapid release of the rolling shutters, but this structure has the following problems:

[0004] 1. In order to achieve the rapid release of the rolling door, since the rolling door dedicated to the silver pavilion is stronger, most of them are reinforced, that is, the weight of the rolling door will be greater. When the rolling door is released quickly, its downward speed will be particularly fast. Under the action of acceleration, when the rolling door falls to the ground, there will be a collision, causing damage to the ground;

[0005] 2. When the shutter door is released quickly, if there is someone waiting under it, there will be a safety hazard;

[0006] 3. When quick release is not required, if the motor and reducer combination is separated from the reel, the rolling door will close quickly, which is unsafe.

DETAILED DESCRIPTION

[0033] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0034] Example 1: See Figures 1 to 3 As shown, a rolling door deceleration brake system for silver pavilions includes a rotating shaft 115 and a brake disc 118 coaxially mounted on one end of the rotating shaft 115, and the end of the rotating shaft 115 is rotatably mounted on the top of the column 116 through a supporting component;

[0035] The brake disc 118 is also provided with a brake component 2 outside thereof, which can clamp and limit the brake disc 118. The brake component 2 is connected to the column 116 via a connecting mechanism 21.

[0036] One end of the connecting mechanism 2 is connected to the upper side wall of the column 116 , and the brake component 2 is connected to the other end of the connecting mechanism 21 .

[0037] The utility model also provides a bank-specific rolling door, which includes the above-mentioned silver pavilion-specific rolling door deceleration brake system. The two ends of the rotating shaft are respectively connected through the support component and the top of a column, a brake disc is arranged at one end of the rotating shaft, and a driving connection disc is arranged at the other end, and the driving connection disc is used to connect with the driving mechanism, and the rotation of the rotating shaft is driven by the driving mechanism and the driving connection disc, and the door body of the rolling door is installed on the rotating shaft, and the door body is rolled up or released by the rotation of the rotating shaft.

[0038] Among them, when it is necessary to unwind the door body, especially when it is necessary to unwind quickly, the driving mechanism will directly separate from the driving connection disk at the end of the rotating shaft, and the door body will be released due to its own weight. In this process, the rotating shaft will rotate, thereby realizing the release of the door body, that is, the unwinding of the rolling door. When unwinding, when the bottom of the door body is close to the ground, the brake component clamps the brake disc, thereby reducing the unwinding speed of the door body, and even the brake component completely clamps the brake disc, so that the brake disc stops, that is, the door body is braked, so that the door body is no longer unwound. Of course, when the door body is unwinding, the brake component can also use a certain clamping force on the brake disc, but it will not completely clamp the brake disc, so as to reduce the rotation speed of the rotating shaft and reduce the unwinding speed of the door body. The setting of the connecting mechanism can install the brake component so that the brake component can be away from the column and will not be interfered by the supporting component. Among them, in this embodiment, the top plane of the brake disc will be above the top surface of the supporting component, and the bottom of the brake disc will be close to the top of the column. In this way, the brake component cannot be below the brake disc, but can only be set on the front side, rear side or above between the front and rear sides of the brake disc axis. Since these positions are far away from the column, in order to facilitate the installation of the brake component, the brake component and the column are connected through a connecting mechanism, and the brake component is directly supported and positioned by the column.

[0039] The brake component 2 is provided with a brake groove, the outer edge of the brake disc 118 is inserted into the brake groove, and there is a gap between the two side walls of the brake disc 118 and the inner wall of the brake groove.

[0040] In the present invention, the brake component 2 is a brake caliper. The brake groove is arranged in the middle of the brake caliper. In this embodiment, the top of the brake disc 118 is located in the brake groove, that is, the brake component 2 is located at the top of the brake disc 118.

[0041] The brake caliper is a hydraulic disc brake caliper, and an oil pipe access pipe 22 is provided on the hydraulic disc brake caliper. The hydraulic disc brake caliper is connected to a hydraulic drive control component via the oil pipe access pipe 22;

[0042] The hydraulic drive control component is configured to control the hydraulic disc brake caliper to clamp or release the brake disc.

[0043] Among them, brake pads are respectively arranged on the inner and outer sides of the brake groove. In the initial state, there is a distance between the inner and outer sides of the brake disc and the brake pads on both sides. When the brake disc needs to be clamped and limited, the hydraulic drive control component supplies hydraulic oil through the oil pipe access pipe, thereby driving the brake pads on both sides to clamp the brake disc, and the brake pads rub the brake disc, thereby clamping the brake disc and limiting the rotation speed of the rotating shaft. Among them, the greater the force of the brake pad on the brake disc, the slower the rotation speed of the brake disc and the rotating shaft, and the slower the unwinding speed of the door body. The hydraulic drive control component is used to control the oil supply pressure to the brake component, thereby adjusting the clamping force of the brake component on the brake disc, thereby realizing the unwinding speed adjustment of the rotating shaft and adjusting the unwinding speed of the door body.

[0044] See also Figure 1 , 2 As shown, the connecting mechanism 21 includes a lower connecting portion 210 and an upper connecting portion 211, the lower connecting portion 210 is fixedly connected to the side wall of the column 116, one end of the upper connecting portion 211 is connected to the side wall of the lower connecting portion 210, and the brake component 2 is connected to the other end of the upper connecting portion 211.

[0045] Among them, in this embodiment, since it is applied to a rolling door, the size of the rotating shaft will not be very small, the size of the brake pad is larger than the size of the rotating shaft, and the brake component is arranged on the top of the brake disc, so that there is a certain distance between the brake component and the column.

Therefore, the connection between the connecting mechanism and the column is under great pressure and is prone to cracking, bending, etc. Therefore, an intermediate positioning component is also provided on the connecting mechanism to increase the connection support points of the connecting mechanism, thereby increasing the strength of the connecting mechanism, preventing problems such as cracking and deformation at the connection between the connecting mechanism and the column, extending the service life, and ensuring the stability of use. Among them, in this embodiment, the intermediate positioning component is provided on the upper first connecting plate.
