The main functions are heat preservation, dust prevention, insect prevention, sound insulation, windproof, etc., so that the workshop can maintain constant temperature, humidity and clean working environment. Nowadays, fast doors are increasingly used in various occasions, but emergency opening after power failure has always been a common problem in the industry. Once encountering emergencies such as fire, if the fast door is in a closed state, it will cause certain problems for emergency escape and evacuation of personnel.

[0003] At present, the general solution to the above problems is to set up a swing door for personnel to pass next to the rapid door, so that people can pass through the swing door in an emergency. However, due to environmental, space, cost and other constraints, this cannot be achieved in many cases.

[0004] If the current fast door loses power, it is usually necessary to use a crank or other tool to shake the motor to slowly raise the door. It is necessary to find a ladder to climb up, which is very laborious and slow, and difficult to achieve in an emergency.

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] The utility model provides Figure 1-5 The electric emergency escape fast door which can be opened without power supply as shown in the figure comprises a first column 1 and a second column 11, the first column 1 and the second column 11 are used as the supporting structure of the door body, the distance and height between the two can be adjusted according to actual needs to meet the use requirements of different scenes, the interior of the second column 11 is a hollow structure, the top of the first column 1 and the second column 11 is fixedly installed with a cover shell 2, the cover shell 2 protects the door curtain 4 from the influence of the external environment, and at the same time enhances the overall stability of the door body, and a cover shell 2 is provided between the first column 1 and the second column 11 and below the cover shell 2. A door curtain 4 is provided, and the door curtain 4 needs to be made of high-quality materials, so that it has good heat preservation, dustproof, insect-proof, soundproof and windproof functions, so as to ensure the cleanliness and constant temperature of the workshop environment. A driving box 3 is fixedly installed on the top outer wall of the No. 1 column 1, and a release mechanism 5 is provided inside the top of the No. 2 column 11 and located at the same end of the cover 2. In an emergency, such as fire, the release mechanism 5 can automatically rotate through the counterweight block 51, the winding wheel 52 and the support rod 53, and drive the shaft rod 6 to automatically rotate, so that the door curtain 4 is quickly raised to ensure that the personnel evacuation passage is unobstructed;

[0028] The release mechanism 5 comprises:

[0029] A counterweight block 51 is disposed at the lower part of the second column 11, and a sling 54 is connected to the upper part of the counterweight block 51;

[0030] The support rod 53 is arranged on the top of the second column 11 and is located inside one end of the cover shell 2. The support rod 53 is fixedly sleeved with a reel 52, and the upper end of the sling 54 is wound around the reel 52.

[0031] Furthermore, in the above technical solution, a shaft 6 is provided inside the cover shell 2, and the upper end of the door curtain 4 is wound on the shaft 6. The winding direction of the door curtain 4 and the shaft 6 is opposite to the winding direction of the sling 54 and the winding wheel 52. Therefore, when the shaft 6 rotates forward and drives the door curtain 4 to be wound, the forward rotation of the winding wheel 52 drives the sling 54 to be released in the reverse direction. When the shaft 6 rotates reversely and drives the door curtain 4 to be released, the reverse rotation of the winding wheel 52 drives the sling 54 to be wound in the forward direction.

[0032] Furthermore, in the above technical solution, the driving box 3 is fixedly installed with a support frame 31, and a bidirectional motor 7 is fixedly installed on the support frame 31. The position of the bidirectional motor 7 corresponds to the position of the shaft rod 6. The bidirectional motor 7 provides power to make the door curtain 4 rise and fall quickly, and the output end of the bidirectional motor 7 is fixedly connected to one end of the shaft rod 6.

[0033] Furthermore, in the above technical solution, a motor brake 8 is installed on the output end of the bidirectional motor 7, and a brake 81 is installed on the outside of the brake disc of the motor brake 8. The tail end of the brake 81 is connected with a pull rope 9. The motor brake 8 brakes to prevent the shaft rod 6 and the output end of the bidirectional motor 7 from rotating under the action of the gravity of the door curtain 4, causing the door curtain 4 to slide down.

[0034] Furthermore, in the above technical solution, a through slot 32 is provided at the bottom of the driving box 3, and the lower end of the pull rope 9 passes through the through slot 32, so that the brake 81 of the motor brake 8 can be manually opened by controlling the pull rope 9, thereby starting the release mechanism 5 to quickly raise the door curtain 4.

[0035] Furthermore, in the above technical solution, one end of the shaft 6 away from the bidirectional motor 7 is fixedly connected to one end of the support rod 53 , and one end of the support rod 53 away from the shaft 6 is rotatably connected to the inner wall of the cover shell 2 .

[0036] The utility model provides an electric emergency escape fast door that can be opened when power is off. When in use, its working process is as follows:

[0037] When the power is on, the fast rolling door controls the forward and reverse rotation of the shaft 6 through the two-way motor 7 in the driving box 3, so that the door curtain 4 can be automatically lifted, opened or closed. When the power is on, when the two-way motor 7 controls the forward and reverse rotation of the shaft 6, the end of the shaft 6 away from the two-way motor 7 synchronously drives the support rod 53 and the winding wheel 52 to perform forward and reverse rotation. Since the upper end of the sling 54 is wound around the winding wheel 52, when the winding wheel 52 follows the forward and reverse rotation of the two-way motor 7, the sling 54 is wound or released on the winding wheel 52. Since the counterweight 51 is connected to the lower end of the sling 54, when the sling 54 is wound or released on the winding wheel 52, the counterweight 51 is lifted and lowered inside the second column 11.

[0038] When the door curtain 4 of the fast door is in a closed state, the reel 52 reels the sling 54 so that the counterweight 51 is suspended above the inside of the second column 11. If a power outage suddenly occurs at this time, the two-way motor 7 cannot control the door curtain 4 to open. At this time, the pull rope 9 under the drive box 3 is pulled, and the pull rope 9 pulls the brake 81 to release the brake of the motor brake 8, and then the counterweight 51 falls freely under the action of gravity. Since the torque generated by the counterweight 51 is always greater than the torque generated by the door curtain 4, the counterweight 51 pulls the sling 54 to rotate the reel 52. As the reel 52 rotates, the shaft 6 rotates synchronously, driving the door curtain 4 to be retracted at this time, thereby quickly opening the door curtain 4, solving the problem that the door curtain 4 of the fast door cannot be opened or is too time-consuming and laborious to open in the event of an unexpected power outage.

[0039] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
