Description

Technical Field

[0001] This utility model relates to the field of fire-fighting equipment technology, and in particular to an adjustable fire hose bracket. Background Technology

[0002] Fire hoses are water-spraying tools used for firefighting. When connected to a fire hose, they spray a dense and powerful stream of water. They have advantages such as long range and large water volume. Based on different jet patterns and characteristics, they can be divided into: straight stream hoses, spray hoses, and multi-purpose hoses. The most commonly used hoses are straight stream and spray hoses. During firefighting operations, when performing cooling and firefighting tasks at fixed points, fixed brackets are used to secure the fire hoses.

[0003] Patent application number CN202322911064.4 discloses a fire hose fixing bracket, including a hose body, a frame externally mounted on the hose body, an anti-slip plate at the bottom of the frame, and a processing component externally mounted on the frame. The processing component includes a disassembly / assembly component located inside the frame, and an adjustment component at the bottom of the disassembly / assembly component. This fire hose fixing bracket, with the adjustment component as one part, allows for height adjustment of the frame when fixed-point fire extinguishing is required. A screw is rotated within a sleeve rod to adjust the fire extinguishing height. While the frame structure for fixing the hose body is rotatably located inside the bracket, and the adjustment component supports the frame for angle adjustment, the single-axis design of the frame and the entire bracket means that adjusting the nozzle spray direction during fire extinguishing requires moving the entire bracket, which is time-consuming, labor-intensive, and affects fire extinguishing efficiency.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes an adjustable fire hose bracket, including a trolley 1, an adjusting column 4 at the upper end of the trolley 1, the adjusting column 4 being rotatably connected to the trolley 1, and a first power component for controlling the rotation of the adjusting column 4 on the inner side of the trolley 1.

[0024] An adjustment frame 2 is provided at the upper end of the adjustment column 4. The adjustment frame 2 is fixedly connected to the adjustment column 4. A gun head clamp 9 for fixing the gun head is provided on the inner side of the adjustment frame 2. The left and right sides of the gun head clamp 9 are rotatably connected to the adjustment frame 2 through the adjustment shaft 14. A second power component for controlling the rotation of the gun head clamp 9 is provided on the outer side of the adjustment frame 2.

[0025] The water gun nozzle is fixed on the nozzle clamp 9. The second power component controls the rotation of the nozzle clamp 9 to adjust the nozzle spray angle. The first power component controls the rotation of the adjusting column 4 to adjust the water gun spray direction, ensuring that the sprayed water can fully cover the fire source and has good flexibility.

[0026] The upper end of the trolley 1 is equipped with a fixed plate 3, which is fixedly connected to the trolley 1. The lower end of the adjusting frame 2 is equipped with at least two roller assemblies, which are slidably connected to an annular groove 12 on the upper end of the fixed plate 3. The adjusting frame 2 is fixed to the adjusting column 4. The first power component drives the adjusting frame 2 to rotate through the adjusting column 4. When adjusting the direction of the water gun, the roller assembly fixed at the lower end of the adjusting frame 2 will also rotate. The annular groove 12 on the upper end of the fixed plate 3 cooperates with the roller assembly to support and limit the adjusting frame 2 from the bottom, ensuring that the adjusting frame 2 will not tilt during rotation and improving the stability of the water gun spray.

[0027] Specifically, the roller assembly includes a support rod 10, the upper end of which is fixedly connected to the adjusting frame 2, and a ball bearing 11 at the lower end of the support rod 10, which is slidably connected to the annular groove 12. The support rods 10 are evenly arranged circumferentially along the axis of the adjusting column 4. When the adjusting column 4 drives the adjusting frame 2 to rotate, the adjusting frame 2 will rotate along with the support rods 10. The ball bearing 11 at the bottom of the support rod 10 slides along the annular groove 12, which guides the support rod 10. During the movement of the support rod 10, it supports the adjusting frame 2 from the bottom, preventing the adjusting frame 2 from tilting during rotation.

[0028] Regarding the gun head clip 9:

[0029] The nozzle clamp 9 includes an arc-shaped support plate 91, with an arc-shaped pressure plate 92 at its upper end. One side of the arc-shaped support plate 91 is rotatably connected to one side of the arc-shaped pressure plate 92. The other side of the arc-shaped support plate 91 and the arc-shaped pressure plate 92 has a latch 93, and a fixing bolt 94 is fitted onto the latch 93. The top of the arc-shaped pressure plate 92 has a tensioning and anti-detachment component. By rotating the fixing bolt 94, the fixing bolt 94 is unscrewed from the latch 93, releasing the fixation between the two latches 93. The arc-shaped pressure plate 92 can then be opened from above the arc-shaped support plate 91, allowing the water gun nozzle to be placed inside the arc-shaped support plate 91.

[0030] Specifically, the anti-detachment assembly includes multiple adjusting bolts 95 mounted on the top of the arc-shaped pressure plate 92. The adjusting bolts 95 pass through the arc-shaped pressure plate 92 and are threadedly connected to it. Rotating the adjusting bolts 95 screws them into the arc-shaped support plate 91, causing them to contact the top of the gun head. By applying pressure, this prevents the gun head from detaching from the arc-shaped support plate 91 and the arc-shaped pressure plate 92.

[0031] It is worth explaining in detail that one end of the adjusting shaft 14 is fixedly connected to the arc-shaped support plate 91, and the other end of the adjusting shaft 14 is rotatably connected to the adjusting frame 2. The arc-shaped support plate 91 is rotatably set in the center of the adjusting frame 2 through the two adjusting shafts 14. The second power component controls the rotation of the adjusting shafts 14, and the arc-shaped support plate 91 will also rotate accordingly.

[0032] Regarding the first and second power components:

[0033] The first power component includes a worm gear 5, a worm 6, and a first motor 7. The worm gear 5 and worm 6 are rotatably mounted inside the trolley 1. The worm gear 5 is fixedly connected to the adjusting column 4 via a connecting shaft. The worm 6 is positioned to one side of the worm gear 5 and meshes with it. The first motor 7 is fixedly mounted inside the trolley 1, and its output end is fixedly connected to the worm 6. The first motor 7 controls the rotation of the worm 6. As the worm 6 rotates, it meshes with the worm gear 5, causing the worm gear 5 to rotate. Since the worm gear 5 is fixed to the adjusting column 4 via the connecting shaft, the adjusting column 4 will also rotate when the worm gear 5 rotates. The worm gear transmission has a self-locking property. When the worm 6 stops rotating, the adjusting frame 2 and the adjusting column 4 will not rotate due to the meshing of the threads of the worm gear 5 and worm 6, thus improving the stability of the water gun spray.

[0034] The second power component includes a second motor 13, which is fixedly mounted on the outside of the adjusting frame 2. The output end of the second motor 13 is fixedly connected to the adjusting shaft 14. The rotation of the adjusting shaft 14 is controlled by the second motor 13, which will not be described in detail here.

[0035] A bracket 15 is provided below the arc-shaped support plate 91. The lower end of the bracket 15 is fixedly connected to the lower end of the adjusting frame 2. A U-shaped support plate is provided at the upper end of the bracket 15, which cooperates with the outer wall of the arc-shaped support plate 91. In the idle state, the arc-shaped support plate 91 retracts downward under the influence of gravity. At this time, the bracket 15 fixed at the lower end of the adjusting frame 2 will support the arc-shaped support plate 91 from below through the U-shaped support plate, ensuring that the arc-shaped support plate 91 will not shake when the support is moved.

[0036] How this application works:

[0037] The water gun nozzle is fixed to the nozzle clamp 9. The second motor 13 controls the rotation of the adjusting shaft 14, which in turn adjusts the spray angle of the nozzle clamp 9. The first motor 7 drives the worm gear 6 to mesh with the worm wheel 5, causing the adjusting column 4 and the adjusting frame 2 to rotate, thus adjusting the spray direction. When the adjusting frame 2 rotates, the ball bearings 11 at the bottom of the support rod 10 slide along the annular groove 12 of the fixed plate 3, providing support and guidance. The self-locking property of the worm gear ensures that it will not rotate back after being fixed in position. The bracket 15 supports the nozzle clamp 9 when not in use, improving overall stability.
