Description

Technical Field

[0001] The utility model belongs to the technical field of support frames, and in particular relates to an emergency support frame for a rolling shutter door. Background Art

[0002] According to the analysis of the time required for emergency repairs of rolling shutter doors at subway station entrances and exits, when the roller of the rolling shutter door breaks or the connection point falls off, it will be impossible to quickly handle it by lifting the door body, and the rolling shutter door can only be opened by demolition. However, the demolition method has a great impact on the time required for fault handling, seriously affecting the opening and operation time of the station. According to statistics, the demolition method takes an average of 60 minutes, which directly causes the station entrance and exit to be unable to be put into normal use for more than one hour.

[0003] At the same time, when encountering a roller detachment failure, since the ordinary jack only serves as an auxiliary lifting function, it is impossible to effectively fix the bottom of the device and the roller of the rolling door, nor can it drive the roller of the rolling door to rotate. Therefore, it is necessary to use the door body dismantling method to cut the rolling door guide rail, door body connecting piece, and decorative panel, and finally pull the cut and separated rolling door out of the guide rail to restore normal operation of the entrance and exit.

[0004] Therefore, it is particularly important to change the fault handling method of the detachment of the reel connection point. A tool is needed to quickly lift the detachment point so that the reel can restore the horizontal position of the door body in a normal state. Utility Model Content

[0005] The utility model aims to solve the above technical problems at least to a certain extent. To this end, the utility model aims to provide a rolling shutter door emergency support frame.

[0006] The technical solution adopted by the utility model is:

[0007] A rolling door rescue support frame comprises a base, which is connected to the fixed end of a jack. A U-shaped frame is arranged on the movable end of the jack. Two support rods are symmetrically arranged on the U-shaped frame. Pulleys are rotatably installed on the support rods, and the axes of the pulleys are perpendicular to the plane where the U-shaped frame is located.

[0008] Preferably, the base includes a plurality of fixing rods located in the same plane, the fixing rods are all connected to the fixed ends of the scissor jacks, and a movable rod is installed in each fixing rod.

[0009] The beneficial effects of the utility model are:

[0010] The utility model provides a rolling shutter door rescue support frame, which changes the fault handling method of breaking and dismantling into a jacking method, that is, by jacking up the rolling shutter door body, the door body is rotated along with the roller shaft to achieve the purpose of opening the entrance and exit. When the support frame lifts the detached rolling shutter door roller shaft to a horizontal state, the rescue personnel can carry out rescue work by jacking up the rolling shutter door body.

[0011] Compared with the prior art where ordinary jacks cannot ensure the rotation of the reel, the support frame uses a U-shaped frame with a pulley to drive the reel to rotate while fixing the reel, so that the rolling door simulates the normal door opening action and gradually opens the entrance and exit, directly avoiding the need for rescue personnel to cut the rolling door reel connection parts, guide rails, door bodies, decorations and other equipment, and then disassemble the cut door bodies, reducing the original handling time of 60 minutes to 20 minutes, and also reducing the demand for rescue personnel required for rolling door failure handling.

[0015] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention. The components of the embodiments of the present invention generally described and shown in the accompanying drawings herein can be arranged and designed in a variety of different configurations.

[0016] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. 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 a direct connection or an indirect connection through an intermediate medium, or it can be the internal connection of two elements.

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] like Figure 1 and Figure 2As shown, a rolling shutter door rescue support frame of this embodiment includes a base 1, which is the foundation of the entire support frame and is used to support the support frame as a whole and maintain stability. The lower end of the jack 2 is a fixed end, and the upper end is a movable end. The base 1 is connected to the fixed end of the jack 2. A U-shaped frame 3 is provided on the movable end of the jack 2. The jack is used to lift the roller of the rolling shutter door and push the rolling shutter door to a normal horizontal position to facilitate the rotation of the rolling shutter door. Two support rods 4 are symmetrically provided on the U-shaped frame 3, and a pulley 5 is rotatably installed on each support rod 4. The axis of the pulley 5 is perpendicular to the plane where the U-shaped frame 3 is located. The U-shaped frame 3 is used to fix the roller of the rolling shutter door and drive the rolling shutter door to rotate through the pulley 5.

[0019] In this embodiment, the base 1 includes four fixed rods 11 located in the same plane, one end of each fixed rod is connected to the fixed end of the scissor jack 2 to form a cross-shaped structure, and a retractable movable rod 12 is installed in each fixed rod 11. The cross-sections of the fixed rod 11 and the movable rod 12 are both square. The retractable base 1 can be actually adjusted according to the space inside the rolling door decorative panel.

[0020] In this embodiment, the jack 2 is a scissor jack.

[0021] The support frame is designed to be 400*400*250mm in length, width and height respectively. The equipment has a small appearance and size, which is convenient to carry and transport, and meets the internal space of the rolling door inspection port.

[0022] When the rolling door emergency support frame is working, the device is placed according to the position where the rolling door reel falls off, and the support frame is placed in the rolling door decorative package board through the retractable base 1, and the internal space is adjusted by telescoping to ensure the stability of the entire device.

[0023] Then the shutter door reel is clamped in the U-shaped frame 3, and the pulley 5 is ensured to be in a rotatable state. The scissor jack in the middle is shaken by the labor-saving wrench to lift the detached reel to the normal horizontal state of the door body, and the lifting is stopped when the reel is in the normal horizontal state. Finally, the rescue personnel use the jacking fast method to lift the shutter door body. The door body is squeezed upward under the force. With the squeezing of the door body, the shutter door reel rotates under the fixation of the support frame, and the rotational force drives the shutter door body to reel up, so that the faulty door body can be opened.

[0024] The rolling shutter door rescue support frame has obvious functions. It can restore the rolling shutter door reel failure state in a relatively short time, reducing the fault handling time of 60 minutes to 20 minutes. It directly changes the original demolition handling method and adjusts it to open the rolling shutter door by jacking with the assistance of this patent, thereby optimizing the emergency rescue handling steps.

[0025] The present utility model is not limited to the above-mentioned optional implementation modes. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all technical solutions that fall within the scope defined by the claims of the present utility model fall within the protection scope of the present utility model.
