Detailed Implementation

[0028] In related technologies, during the process of extending and retracting fire hoses, fire hose laying mechanisms are prone to causing fire hoses to deviate and twist, which in turn leads to fire hose tangling and knotting, affecting the efficiency of extending and retracting fire hoses.

[0029] To address the aforementioned problems, this utility model provides a hose laying mechanism that can improve the problems of displacement and twisting caused by the hose laying mechanism during the process of laying and retracting fire hoses, avoid the need to spend extra time to sort out fire hoses due to tangling and knotting, and enable fire hoses to be laid and retracted quickly.

[0035] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0036] The following describes in detail the overall structure, working principle, and technical effects of the hose laying mechanism 10 and the fire truck provided by this utility model through embodiments and in conjunction with the accompanying drawings.

[0037] Please see Figures 1 to 3 This utility model provides a hose laying mechanism 10, which is applied to fire trucks to improve the problems of displacement and twisting caused by the hose laying mechanism 10 during the process of laying and retracting fire hoses, and avoids the need to spend extra time to sort out fire hoses due to tangling and knotting.

[0038] The hose laying mechanism 10 includes a first guiding device 100, a third guiding device 500, and a winding device 700. The first guiding device 100 is used to connect to the top wall of the vehicle cab, while the second guiding device 300 and the third guiding device 500 are both used to connect to the top wall of the vehicle body. The first guiding device 100 extends along a first direction to allow the fire hose to move along that direction; the second guiding device 300 extends along a second direction perpendicular to the first direction to allow the fire hose to reciprocate along that second direction. Optionally, the first direction is the direction of travel of the fire truck, and the second direction is a left-right direction perpendicular to the fire truck.

[0039] The third guide device 500 is located between the first guide device 100 and the second guide device 300. That is, the third guide device 500 serves as a transitional guide element between the first guide device 100 and the second guide device 300. Based on this, the extension length of the third guide device 500 gradually increases along the direction close to the second guide device 300, thereby achieving a correspondence between one side and the narrower first guide device 100, and the other side and the wider second guide device 300.

[0040] Based on the above, the winding device 700 is used to connect to the inner wall of the carriage and is located on the side of the second guide device 300 away from the third guide device 500. It is used to wind up or release the fire hose. In a practical scenario, taking the winding of a fire hose as an example, after being guided by the first guide device 100, the fire hose passes through the third guide device 500 and enters the second guide device 300 along the first direction without deviation or twisting. Subsequently, under the guidance of the second guide device 300, the fire hose moves back and forth along the second direction and is evenly wound around the winding device 700.

[0041] As an optional embodiment, the hose laying mechanism 10 also includes a power unit 900. The power unit 900 is driven by the winding device 700, providing power support to ensure that the winding device 700 can smoothly and quickly wind up or unwind the fire hose. Optionally, the power unit 900 is a hydraulic system. Additionally, to ensure the cleanliness of the fire hose, the hose laying mechanism 10 also includes a cleaning device 800. The cleaning device 800 is used to clean the fire hose to remove dust, mud, and other contaminants adhering to its surface.

[0042] Figure 2 Provided for this embodiment Figure 1 A schematic diagram of the structure at point A. (See diagram below.) Figure 1 and Figure 2 As shown, the winding device 700 includes a winding element 710 and a positioning element 730. The positioning element 730 is connected to the winding element 710 and is used to fix the end of the fire hose, facilitating the positioning of the fire hose in a predetermined position and preventing slippage during winding or unwinding. The winding element 710 is used to wind or unwind the fire hose, and its axis extends along a second direction. Based on this, under the guidance of the second guiding device 300, the fire hose reciprocates along the second direction, enabling it to be evenly wound onto the winding element 710.

[0043] like Figure 1 and Figure 2 As shown, when the winding element 710 has a cylindrical structure, the positioning element 730 is connected to the end of the winding element 710, and the power unit 900 is connected to the winding element 710 via a transmission. In the application of winding fire hoses, the operator first wraps one end of the fire hose around the winding element 710, allowing it to engage with the positioning element 730. Then, the power unit 900 is activated, causing the winding element 710 to rotate, thereby rotating the fire hose wound on the winding element 710, thus achieving the winding of the fire hose.

[0044] It should also be noted that in other embodiments, the positioning element 730 can also be connected to other positions of the winding element 710, as long as it does not interfere with the winding and unwinding of the fire hose. Alternatively, the positioning element 730 can also be connected to the end of the fire hose via bolts to ensure the pre-positioning of the fire hose. Further details will not be elaborated here.

[0045] Furthermore, the winding device 700 also includes a limiting roller 750, which is spaced apart from the winding element 710 along the first direction and located on the side of the winding element 710 away from the second guide device 300. This arrangement means that the limiting roller 750 is located between the winding element 710 and the wall of the vehicle. When the fire hose is wound to a certain thickness on the winding element 710, the limiting roller 750 abuts against the fire hose, preventing the fire hose from contacting, colliding with, or rubbing against the wall of the vehicle.

[0046] like Figure 1 As shown, the first guiding device 100 includes a guide arm 110 and two first guardrails 130. The guide arm 110 extends along a first direction, and the two first guardrails 130 are positioned opposite each other on either side of the guide arm 110 along a second direction. Based on this arrangement, the fire hose moves along the first direction under the guidance of the guide arm 110. Furthermore, during this process, the two first guardrails 130 protect the fire hose on both sides, preventing the fire hose from accidentally slipping off the roof of the vehicle and affecting the winding or releasing efficiency.

[0047] Similarly, the third guiding device 500 includes a guide seat 510 and two second guardrails 530, which are arranged opposite each other on both sides of the guide seat 510 along the second direction. Correspondingly, in the second direction, the extension length of the guide seat 510 near the first guiding device 100 is less than the extension length of the end near the second guiding device 300. That is, the guide seat has a trapezoidal structure that is smaller at the front and larger at the back. Based on this, when the fire hose is reciprocated along the second direction under the action of the second guiding device 300, the fire hose has a certain degree of swing freedom in the second direction and will not get stuck.

[0048] Please see Figure 3 , Figure 3 Provided for this embodiment Figure 1 The structural diagram at point B is shown. To further prevent the fire hose from shifting or twisting, the third guiding device 500 also includes two guide rollers 550. Both guide rollers 550 are located at the end of the guide seat 510 near the first guiding device 100 and are spaced apart along the second direction. It is easy to understand that a hose channel is formed between the two guide rollers 550, ensuring that the fire hose always moves along the first direction. In addition, the fire hose contacts the outer wall of the guide rollers 550 when passing through, reducing the resistance when the fire hose passes through the hose channel during storage.

[0049] Please see Figure 4 , Figure 4 Provided for this embodiment Figure 1A schematic diagram of the structure at point C. The second guiding device 300 includes a guide rail 310 and a guide member 330. The guide rail 310 is connected to the top arm of the carriage and extends along a second direction. As described above, the guide rail 310 provided in this application is the axial guide rail 310 of the winding element 710. Based on the above, the guide member 330 is slidably connected to the guide rail 310 and is used for threading the fire hose, so as to drive the fire hose to reciprocate along the second direction (i.e., the axial direction of the winding element 710), making it evenly wound around the winding element 710. In some embodiments, the second guiding device 300 also includes an axial drive element drivenly connected to the guide member 330. By adjusting the moving speed of the guide member 330 and the rotation speed of the reel, it is possible to further ensure that the hose is evenly wound on the winding element 710.

[0050] In summary, this utility model provides a hose laying mechanism 10, including a first guiding device 100, a second guiding device 300, a third guiding device 500, and a winding device 700. The first guiding device 100 is used to connect to the top wall of the vehicle head; the second guiding device 300 and the third guiding device 500 are both used to connect to the top wall of the vehicle compartment; and the winding device 700 is used to connect to the inner wall of the vehicle compartment. Furthermore, the first guiding device 100 extends along a first direction to allow the fire hose to move along that direction; the second guiding device 300 extends along a second direction perpendicular to the first direction to allow the fire hose to reciprocate along that direction. The third guiding device 500 is located between the first guiding device 100 and the second guiding device 300. The winding device 700 is located on the side of the second guiding device 300 away from the third guiding device 500 and is used to wind up or release the fire hose. Based on the above, the problems of deviation and twisting caused by the fire hose laying mechanism 10 during the process of retracting and extending the fire hose have been improved, avoiding the need to spend extra time to sort out the fire hose due to tangling and knotting.

[0051] In addition, this utility model embodiment also provides a fire truck. The fire truck includes a cab, a cargo compartment, and a hose laying mechanism 10 as described in the previous embodiment. Specifically, a first guiding device 100 is connected to the top wall of the cab, a second guiding device 300 is connected to the top wall of the cargo compartment, a third guiding device 500 is connected to the top wall of the cargo compartment, and a winding device 700 is connected to the inner wall of the cargo compartment. Based on the above configuration, this fire truck can also improve the problems of displacement and twisting caused by the hose laying mechanism 10 during the winding and unwinding of fire hoses, avoiding the need to spend extra time tidying up fire hoses due to tangling and knotting. Further details will not be elaborated here.

[0052] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
