Description

Technical Field

[0001] This invention relates to the field of fire-fighting equipment technology, and in particular to a fire hose anti-crushing protection support device. Background Technology

[0002] Fire hoses are crucial water delivery equipment in fire fighting and rescue operations. In actual fire fighting, fire hoses often need to be laid across highways, factory roads, and other areas with high vehicle traffic. However, fire trucks and other vehicles traveling on the road inevitably run over the fire hoses that are crossing the road.

[0003] Currently, in order to prevent vehicles from running over the fire hoses, the traditional approach is to use simple metal guard bridges for protection. These metal guard bridges are usually installed directly across the fire hoses, using the strength of the metal frame to physically isolate the wheel load from the hoses.

[0004] However, existing metal guardrails are usually unable to effectively secure fire hoses under the impact of high-pressure water flow. After high-pressure water flow is introduced, the fire hoses are prone to twisting and rolling due to the back pressure, which may affect their normal use. In addition, traditional metal guardrails are mostly single structures with fixed lengths, making it difficult to adjust the protection length according to the actual road width.

[0005] Therefore, it is necessary to design a fire hose anti-crushing protection support device to solve the problems existing in the above-mentioned prior art. Summary of the Invention

Detailed Implementation

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] Example This invention provides a fire hose anti-rollover protection support device. Please refer to [link / reference]. Figures 1-7 It includes multiple support units 1, and adjacent support units 1 are connected by a detachable connection structure 2; the support unit 1 includes a support shell 11, and the support shell 11 is provided with a clamping component 12 for clamping fire hoses, and the clamping components 12 of adjacent support units 1 are correspondingly provided.

[0025] In this embodiment, the vertical cross-section of the support shell 11 is an isosceles trapezoidal structure, the inclined surfaces 111 on both sides serve as guide surfaces for vehicles to pass through, and the bottom surface is provided with anti-slip textures or fixed anti-slip rubber pads to increase the friction between the support shell and the road surface.

[0026] An inclined plate 112 is fixed inside the support shell 11 to support and fix the inclined surface 111; a first vertical plate 113 is fixed at the junction of the inclined surface 111 and the top surface, and the lower end of the first vertical plate 113 is fixed to the inner bottom wall of the support shell 11; the clamping assembly 12 is arranged in the middle area of ​​the two first vertical plates 113.

[0027] The clamping assembly 12 includes two corresponding clamping bodies 121, which are slidably connected to the support shell 11 via a guide structure 122. The clamping surfaces of the clamping bodies 121 are provided with anti-slip textures or fixed with anti-slip rubber pads to improve the clamping effect on the fire hose. The support shell 11 is provided with an adjustment structure 123, which drives the two clamping bodies 121 to move away from or closer to each other.

[0028] A second vertical plate 114 is fixed between the first vertical plate 113 and the inclined plate 112. The second vertical plate 114 is used to increase the stability of the support shell 11 structure on the one hand, and to cooperate with the first vertical plate 113 to jointly install the adjustment structure 123 on the other hand.

[0029] Specifically, the adjustment structure 123 includes adjustment bolts 1231 on both sides of each clamping body 121. The adjustment bolts 1231 are threadedly connected to threaded sleeves 1232, which are horizontally fixed between the first vertical plate 113 and the second vertical plate 114. Both the first vertical plate 113 and the second vertical plate 114 are provided with through holes for the adjustment bolts 1231 to pass through. The ends of the adjustment bolts 1231 are rotatably connected to the corresponding clamping bodies 121. By turning the adjustment bolts 1231 on both sides of each clamping body 121, under the action of the guide structure 122, the clamping body 121 can achieve the effect of horizontal linear movement. This allows the distance between the two clamping bodies 121 to be adjusted, thus enabling the clamping of fire hoses of different specifications.

[0030] Furthermore, the guide structure 122 includes a guide rod 1221 disposed on the clamping body 121, the end of the guide rod 1221 extending into the guide groove 1222 on the support shell 11 and slidably connected thereto.

[0031] In this embodiment, each clamping body 121 has multiple guide rods 1221 fixed at intervals along its length at both its upper and lower ends. Each guide rod 1221 corresponds to a guide groove 1222, and the guide rod 1221 slides in cooperation with the corresponding guide groove 1222. The multiple guide rods 1221 arranged vertically can guide the adjustment of the distance between the two clamping bodies 121 and provide structural support for the support shell 11 to ensure the overall structural stability of the support shell 11 when a vehicle passes by.

[0032] The present invention effectively improves the overall compressive strength and structural rigidity of the device by using the trapezoidal inclined surface structure of the supporting shell 11 and the cooperation of the internal inclined plate 112, the first vertical plate 113, and the second vertical plate 114. At the same time, the guide rod 1221 on the clamping body 121 further acts as an internal support rod during the clamping process, so that the device can maintain structural stability when facing repeated crushing by vehicles, and is not prone to deformation or breakage, thus extending its service life.

[0033] Furthermore, the clamping assembly 12 also includes a telescopic support assembly 124, the two ends of which are connected to the bottom surfaces of the two clamping bodies 121 respectively. When the two clamping bodies 121 move away from or closer to each other, the telescopic support assembly 124 extends and retracts synchronously.

[0034] In this embodiment, the telescopic support assembly 124 includes two correspondingly arranged mounting slots 1241, which are fixedly connected to the bottom surface of the clamping body 121; a support plate 1242 is provided between the two mounting slots 1241, and both ends of the support plate 1242 extend into the corresponding mounting slots 1241 and are slidably connected thereto.

[0035] When the two clamping bodies 121 move away from or closer to each other, the distance between the two mounting slots 1241 changes synchronously, and the exposed length of the support plate 1242 also increases or decreases. By setting the support plate 1242, the bottom of the fire hose can be supported when the distance between the two clamping bodies 121 is far, so as to improve the stability of clamping the fire hose.

[0036] In addition, to prevent the end of the support plate 1242 from coming out of the corresponding mounting groove 1241, limit strips 1243 are fixed at both ends of the support plate 1242. The limit strips 1243 slide in contact with the inner wall of the mounting groove 1241 and are limited in fit with one side of the opening of the mounting groove 1241.

[0037] This invention provides a telescopic support component 124 that extends and retracts synchronously with the clamping component 12. When clamping fire hoses of different specifications, the bottom of each hose receives appropriate support. This telescopic support component 124 effectively prevents the fire hose from sagging and excessive bending due to its own weight and internal water pressure after high-pressure water flow is introduced. This protects the hose's rubber layer from fatigue damage and ensures that the hose remains straight and unobstructed for a long time, thus guaranteeing the water delivery efficiency.

[0038] Furthermore, the connecting structure 2 includes a first ear plate 21 and a second ear plate 22. The first ear plate 21 and the second ear plate 22 are respectively fixedly connected to the adjacent side of the adjacent support shell 11 and are connected through a shaft 23. One end of the shaft 23 is fixed with a limit cap 24, and the other end is provided with a driving structure 25. The driving structure 25 drives the stop block 26 to move radially along the shaft 23, so that the stop block 26 passes through to the outside of the shaft 23 or retracts into the shaft 23.

[0039] In this embodiment, a guide hole 230 is provided on the side wall of the shaft 23, and the stop block 26 is slidably connected in the guide hole 230; the drive structure 25 includes a connecting rod 251 fixedly connected to the stop block 26, and the connecting rod 251 is slidably connected to the shaft plate 252 fixed inside the shaft 23; a reset member 253 is provided on the shaft plate 252, the reset member 253 is connected to one side of the connecting rod 251, and the other side of the connecting rod 251 is connected to the drive part 254. The drive part 254 and the reset member 253 together drive the connecting rod 251 to move radially along the shaft 23.

[0040] Specifically, the reset component 253 is a tension spring, which is sleeved on the connecting rod 251. One end of the tension spring is fixed to the shaft plate 252, and the other end is fixed to the connecting rod 251. The drive unit 254 includes a drive rod 2541 connected to the shaft 23. A cone 2542 is fixed to the end of the drive rod 2541. The conical surface of the cone 2542 contacts and engages with the connecting rod 251 at the end away from the stop block 26. Driven by the drive rod 2541, the cone 2542 moves towards the connecting rod 251. Under the action of the cone surface of the cone 2542, the connecting rod 251 moves radially away from the axis of the shaft 23. The connecting rod 251 drives the stop block 26 to move synchronously, so that the stop block 26 is exposed outside the guide hole 230. The stop block 26 and the limit cap 24 respectively contact and cooperate with the corresponding first ear plate 21 or second ear plate 22 to achieve the effect of fixing the shaft 23. When it is necessary to disassemble the shaft 23, the drive rod 2541 drives the cone 2542 to move in the opposite direction. Under the action of the spring return force, the stop block 26 and the connecting rod 251 move radially towards the axis of the shaft 23, so that the stop block 26 retracts into the guide hole 230, and the shaft 23 can be disassembled.

[0041] By setting the connection structure 2 as described above, it is convenient to assemble and disassemble the support shell 11. On the other hand, it also makes the adjacent support shells 11 hinged, so that the support shells 11 can make adaptive slight swings when the vehicle passes by, effectively relieving and releasing the concentrated stress caused by uneven road surface or uneven wheel rolling, and improving the overall compressive bearing capacity and service life.

[0042] Furthermore, the drive rod 2541 is a threaded rod, which is threaded to the inner wall of the shaft 23, and the threaded rod has a groove-shaped structure at the end away from the cone 2542 for cooperating with an external screwing tool.

[0043] In this embodiment, by using an external screwing tool in conjunction with a grooved structure to drive the threaded rod to rotate, the cone 2542 can rotate while simultaneously moving in a straight line, thus achieving the effect of driving the stop block 26 to move radially.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
