Description

Technical Field

[0001] This utility model belongs to the field of rescue equipment technology, specifically relating to a fall protection support structure for emergency rescue equipment. Background Technology

[0002] Currently, during rescue operations, in the event of an emergency such as a fire on a high-rise building, debris or other objects may fall from the upper floors, causing injuries and endangering the lives of the public and threatening the lives of rescue personnel.

[0003] In the past, some rescue sites may have relied on simple protective barriers, such as temporary wooden boards or plastic sheets. These protective measures not only had limited protection range and could not provide all-round protection, but also could cause people to be injured by the flying fragments when faced with falling objects with greater impact force, thus failing to provide reliable protection.

[0004] Some rescue equipment uses fixed protective panels, but these panels are large and extremely inconvenient to transport and store, severely hindering the rapid deployment and flexibility of rescue operations. Furthermore, some protective devices are cumbersome to deploy and retract, consuming significant time and manpower, and failing to provide effective protection for rescue personnel quickly in emergency situations.

[0005] To address this, we propose a fall protection support structure for emergency rescue equipment. This device not only provides comprehensive protection but also allows for folding and storage, taking up little space and making it easy to unfold and store. Utility Model Content

[0006] The purpose of this utility model is to provide a fall protection support structure for emergency rescue equipment. This device can not only provide comprehensive protection, but also be folded and stored, occupying a small area and being easy to unfold and store.

[0007] The specific technical solution adopted by this utility model is as follows:

[0008] An emergency rescue equipment anti-fall support structure includes a base plate, and two supports are provided on the top of the base plate. Each support is provided with a retractable and foldable arc-shaped protective plate assembly. The two arc-shaped protective plates form a semi-circular protective plate with all-round protection.

[0009] Each of the brackets is hinged to one side with a drive plate. A gear is provided at the hinge point between the drive plate and the bracket. The other end of the drive plate is connected to the arc-shaped protective component. Both sides of the base plate are provided with housings. A drive component is provided inside the housing. A sliding plate is provided on the drive component. The sliding plate is provided with meshing teeth that mesh with the gear.

[0010] Furthermore, the arc-shaped protective plate assembly includes a first arc-shaped plate connected to the bracket, the first arc-shaped plate having a first arc-shaped groove, a second arc-shaped plate being disposed inside the first arc-shaped groove, the second arc-shaped plate having a second arc-shaped groove, a third arc-shaped plate being disposed inside the second arc-shaped groove, a third arc-shaped groove being formed on the third arc-shaped plate, and a fourth arc-shaped plate being rotatably connected to the drive plate being disposed inside the third arc-shaped groove.

[0011] Furthermore, a buffer layer is provided on the first arc-shaped plate, the second arc-shaped plate, the third arc-shaped plate, and the fourth arc-shaped plate.

[0012] Furthermore, the drive assembly includes a motor mounted on the housing, a rotating rod mounted on the output end of the motor, the rotating rod having opposite threads, a matching threaded sleeve fitted on the opposite threads, and the top of the threaded sleeve being connected to the sliding plate.

[0013] Furthermore, the housing is provided with a groove that matches the threaded sleeve.

[0014] Furthermore, sliding grooves are provided on both sides of the base plate, and extension plates are provided inside the sliding grooves.

[0015] The technical effects achieved by this utility model are as follows:

[0016] When the curved protective panel assembly needs to be deployed for protection, the drive assembly is activated, pushing the two sliding plates to move relative to each other. Then, the meshing teeth on the sliding plates interact with the gear, causing the gear to rotate clockwise. Due to the hinged relationship between the gear and the drive plate, the clockwise rotation of the gear will drive the drive plate to rotate clockwise around its hinge point with the bracket, thereby pulling the connected curved protective panel assembly outward. During deployment, the internal folding structure of the arc-shaped protective panel assembly gradually extends, forming a stable semi-circular protective area. When the rescue operation is completed or protection is no longer needed, the drive assembly rotates in the opposite direction, causing the two sliding plates to move in opposite directions. The meshing teeth on the sliding plates interact with the gears again, causing the gears to rotate counterclockwise. The counterclockwise rotation of the gears causes the drive plate to rotate counterclockwise around its hinge point with the support, which in turn pushes the arc-shaped protective panel assembly to retract inward. During the retraction process, the internal folding structure of the arc-shaped protective panel assembly gradually folds up, ultimately allowing the arc-shaped protective panel assembly to be compactly stored on the support, reducing space occupation and facilitating the transportation and storage of the equipment. Through this precise and stable drive method, the arc-shaped protective panel assembly can be quickly and accurately deployed and retracted, providing timely and effective protection against falling objects for emergency rescue operations.

[0023] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: a fall protection support structure for emergency rescue equipment, including a base plate 1, two supports 2 are provided on the top of the base plate 1, and each support 2 is provided with a retractable and foldable arc-shaped protective plate assembly. The two arc-shaped protective plates form a semi-circular protective plate with all-round protection.

[0025] Each bracket 2 has a drive plate 3 hinged to one side. A gear 4 is provided at the hinge point between the drive plate 3 and the bracket 2. The other end of the drive plate 3 is connected to the arc-shaped protective component. Both sides of the base plate 1 are provided with a housing 6. The housing 6 is provided with a drive component. The drive component is provided with a sliding plate 5. The sliding plate 5 is provided with meshing teeth 7 that mesh with the gear 4.

[0026] The arc-shaped protective plate assembly includes a first arc-shaped plate 8 connected to the bracket 2, a first arc-shaped groove on the first arc-shaped plate 8, a second arc-shaped plate 9 inside the first arc-shaped groove, a second arc-shaped groove on the second arc-shaped plate 9, a third arc-shaped plate 10 inside the second arc-shaped groove, a third arc-shaped groove on the third arc-shaped plate 10, and a fourth arc-shaped plate 11 rotatably connected to the drive plate 3 inside the third arc-shaped groove.

[0027] The drive plate 3 drives the fourth arc plate 11 into the third arc groove, the third arc plate 10 into the second arc groove, and the second arc plate 9 into the first arc groove, thus completing the folding and storage.

[0028] Furthermore, the first arc-shaped plate 8, the second arc-shaped plate 9, the third arc-shaped plate 10, and the fourth arc-shaped plate 11 are all equipped with a buffer layer. The buffer layer can reduce the impact force of falling objects from a height and prevent people from being injured. At the same time, the first arc-shaped plate 8, the second arc-shaped plate 9, the third arc-shaped plate 10, and the fourth arc-shaped plate 11 are all made of high-strength materials, such as plexiglass (PC board) and tempered glass, so that staff can observe the external situation and take corresponding measures.

[0029] Furthermore, a buffer plate (not shown in the figure) can be installed on the first arc-shaped plate 8 to further prevent objects from falling from heights.

[0030] The arc-shaped arrangement of the first arc plate 8, the second arc plate 9, the third arc plate 10, and the fourth arc plate 11 can decompose the impact force, thereby reducing the impact force.

[0031] Meanwhile, the drive assembly includes a motor 12 mounted on the housing 6. A rotating rod 13 is mounted on the output end of the motor 12. The rotating rod 13 has opposite threads, and a matching threaded sleeve 14 is fitted on the opposite threads. The top of the threaded sleeve 14 is connected to the sliding plate 5. The rotating rod 13 is driven to rotate by the motor 12, and the rotating rod 13 drives the two threaded sleeves 14 to make the two sliding plates 5 move relative to each other or in opposite directions.

[0032] The housing 6 has a groove 15 that matches the threaded sleeve 14, through which the threaded sleeve 14 can be moved.

[0033] The base plate 1 has sliding grooves 16 on both sides, and an extension plate 17 is provided inside the sliding groove 16. The extension plate 17 can improve the stability of the entire device and can be stored when not in use, reducing the floor space occupied.

[0034] The bottom of the base plate 1 is equipped with pulleys, which can facilitate movement and fixation.

[0035] The working principle of this utility model is as follows: When the arc-shaped protective plate assembly needs to be deployed for protection, the drive assembly is activated, pushing the two sliding plates 5 to move relative to each other. Then, the meshing teeth 7 on the sliding plates 5 interact with the gear 4, causing the gear 4 to rotate clockwise. Due to the hinged relationship between the gear 4 and the drive plate 3, the clockwise rotation of the gear 4 will drive the drive plate 3 to rotate clockwise around its hinge point with the bracket 2, thereby pulling the arc-shaped protective plate assembly connected to it to unfold outward. During the unfolding process, the internal folding structure of the arc-shaped protective plate assembly gradually extends, forming a stable semi-circular protective area. When the rescue work is completed or the protection is no longer needed, the drive assembly rotates in the opposite direction, thereby driving the two sliding plates 5 to move in opposite directions. The meshing teeth 7 on the sliding plates 5 interact with the gear 4 again, driving the gear 4 to rotate counterclockwise. The counterclockwise rotation of the gear 4 causes the drive plate 3 to rotate counterclockwise around its hinge point with the bracket 2, thereby pushing the arc-shaped protective plate assembly to retract inward. During the retraction process, the internal folding structure of the arc-shaped protective plate assembly gradually folds up, ultimately allowing the arc-shaped protective plate assembly to be compactly stored on the bracket 2, reducing space occupation and facilitating the transportation and storage of the equipment. Through this precise and stable drive method, the arc-shaped protective plate assembly can be quickly and accurately unfolded and retracted, providing timely and effective protection against falling objects for emergency rescue work.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
