Description

Technical Field

[0001] The utility model relates to the technical field of water hose reeling mechanisms, in particular to a special self-propelled water hose reeling mechanism. Background Art

[0002] A self-propelled hose is a specially designed firefighting device, usually used to respond to fire emergencies. It is a flexible pipe with a high-pressure water source that can be towed or automatically moved to the fire scene to quickly provide water to the fire source for fire extinguishing.

[0003] In the prior art, the winding and laying of water hoses mainly rely on manpower, which greatly increases the labor intensity of firefighters and has low work efficiency. The winding mechanism currently on the market mainly adopts an electric wheeled chassis, on which a swing arm and a manual clamping device are installed. The size is large, and after the water hose is wound, it is difficult to load and unload the winding mechanism and the transport vehicle. It requires third-party auxiliary mechanisms and personnel to complete, which is not only time-consuming, but also increases the loading and unloading costs, which is very inconvenient. For this reason, we specially propose a self-propelled water hose winding mechanism. Utility Model Content

[0004] The utility model aims to solve the problems existing in the background technology and proposes a self-propelled hose reeling mechanism with the function of quick loading and unloading.

[0006] Preferably, mounting pins are provided between the output end and the mounting end of the hydraulic cylinder A and the frame body of the mounting frame and the plate body of the mounting seat, respectively.

[0009] Preferably, the roller is located in the clamping cavity of the guide column.

[0010] Compared with the prior art, the utility model has the following beneficial technical effects:

[0011] The utility model has a simple overall structure and is easy to operate. The telescopic arm can be pushed and extended under the action of the hydraulic cylinder B, so that the telescopic arm drives the reeled water hose to move and place it in the transport vehicle by itself. The hydraulic push rod A can be used to adjust the angle of the flip arm so that the flip arm drives the telescopic arm to move, thereby making it more convenient to load and unload the reeled water hose in the transport vehicle without consuming extra manpower and material resources, greatly reducing the work intensity of firefighters and improving work efficiency.

DETAILED DESCRIPTION

[0016] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] Embodiment 1

[0018] like Figure 1-3As shown, the utility model proposes a self-propelled water hose winding special mechanism, including a water guide shell 1 and a crawler chassis 4 installed at the bottom of the front and rear sides of the water guide shell 1, a wheel cover 2 is installed on the top of the crawler chassis 4, and one side of the wheel cover 2 is fixedly connected to the water guide shell 1. The setting of the wheel cover 2 can protect the crawler chassis, and the shell of the wheel cover 2 is equipped with a mounting frame 10, and the lower part of the mounting frame 10 is fixedly connected to the upper part of the wheel cover 2. A flip arm 7 is installed in the frame body of the mounting frame 10, and one end of the flip arm 7 is rotatably connected to the mounting frame 10. A hydraulic cylinder B14 of an extendable telescopic arm 6 is installed in the inner cavity of the flip arm 7, and the mounting end of the telescopic arm 6 is fixedly connected to the top of the flip arm 7. A mounting seat 15 is provided in the shell of the wheel cover 2, and one side of the mounting seat 15 is fixedly connected to the inner wall of the wheel cover 2, and a hydraulic cylinder A3 is installed between one end of the plate body of the mounting seat 15 and the bottom frame body of the mounting frame 10.

[0019] In this embodiment, the crawler chassis 4 is mainly used to facilitate the movement of the special hose winding mechanism in areas with complex terrain. Since the hose is often used in flood disaster areas, and the terrain environment in these areas is relatively harsh, it is difficult for ordinary winding mechanisms to move in such complex terrains. Therefore, installing the crawler chassis 4 is beneficial to improving the practicality of the special hose winding mechanism. A wheel cover 2 is installed on the top of the crawler chassis 4, which not only protects the crawler chassis 4, but also facilitates the installation of subsequent functional structures. The housing of the wheel cover 2 is provided with a mounting frame 10, and a flip arm 7 is installed in the frame of the mounting frame 10. One end of the mounting frame 10 is installed in the wheel cover 2 through a pin shaft, so that the mounting frame 10 can rotate around a fixed point and adjust the angle conveniently. The end of the flip arm 7 away from the mounting frame 10 is connected with a telescopic arm 6, and a hydraulic cylinder B14 that can extend the telescopic arm 6 is installed in the inner cavity of the flip arm 7. A mounting seat 15 is provided in the housing of the wheel cover 2, and a hydraulic cylinder A3 is installed between one end of the plate body of the mounting seat 15 and the bottom frame of the mounting frame 10. Under the action of the hydraulic cylinder B14, the telescopic arm 6 can be pushed and extended, so that the telescopic arm 6 drives the rolled-up water hose to move and place it in the transport vehicle by itself, so as to facilitate the loading and unloading of the rolled-up water hose in the transport vehicle without consuming extra manpower and material resources, greatly reducing the work intensity of firefighters and improving work efficiency.
