Description

Technical Field

[0001] The utility model relates to the technical field of fire trucks, in particular to a fast-retracting fire truck. Background Art

[0002] A fire truck, also known as a fire truck, is a vehicle designed and manufactured to accommodate firefighters and equipped with various firefighting equipment and fire extinguishing agents. It is used by firefighters for firefighting, firefighting assistance, and fire rescue operations. Fire departments in most countries, including China, also use it for other emergency rescue purposes. Fire trucks transport firefighters to disaster sites and provide a variety of tools for their relief efforts. During rescue operations, fire trucks require the connection of fire hoses to extend their reach. Existing fire hoses typically require manual reeling after installation and placement inside the fire truck.

[0003] For example, the utility model with application number 202122800690.7 discloses a fire truck that can automatically reel in a fire hose. The utility model drives the reeling assembly through a motor, so that the fire hose can be automatically wound on the reeling assembly. Moreover, through the design of the adjustment unit in the reeling assembly, the diameter of the reeling plate used for winding the fire hose can be changed, thereby loosening the rolled fire hose, that is, when the fire hose is taken out for manual docking, it is convenient to remove it from the reeling assembly.

[0004] Similar to the above application, there are still some deficiencies:

[0005] This type of fire truck that can reel in a fire hose by itself uses a motor to wind the fire hose around a reeling assembly to complete the reeling work. However, during the reeling process, the reeling fire hose is always in contact and rubbed with the ground due to the low reeling height and close to the ground. Therefore, during the reeling process, the bottom of the fire hose rubs against the ground, causing the bottom of the fire hose to wear or even break and leak, and the water in the fire hose cannot be squeezed out, affecting the reeling efficiency.

[0006] For this reason, a fast-retracting fire truck is designed to optimize the above-mentioned problems. Utility Model Content

[0007] The main purpose of the utility model is to provide a fast retracting fire truck, which can lift the fire hose part up and off the ground when retracting the fire hose, thereby reducing problems such as friction damage to the fire hose caused by winding and dragging. The fire hose is suspended in the air to facilitate the stretching and flattening of the pipe body. The suspension and manual auxiliary adjustment can reduce the workload of laying the fire hose in advance, thereby improving the retracting efficiency and the protection effect of the fire hose.

[0008] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0009] The cam is fixed on the top of the cam and is fixed with a plurality of movable plates, and the movable plates are installed on the inner side wall of the cam and are located on the side of the cam.

[0010] Preferably: the mounting mechanism includes a movable rod and a sliding hole, the movable rod is located at one end of the second roller, and the movable rod is rotatably connected to the second roller, the sliding hole is opened on one side of the movable plate, and the sliding hole and the movable rod are slidably connected, and the outer thread of the movable rod is threaded to install the screw tube three.

[0011] Preferably: a limit plate is slidably installed on the outer side of the fixed rod, and screws are symmetrically arranged on one side of the limit plate away from the fixed plate, and the ends of the screws all pass through and extend to the outside of the mounting plate, and a second screw tube is installed on the outer thread of the screw, and the second screw tube is rotatably connected to the mounting plate.

[0012] Preferably, a protective plate is hingedly mounted on the end of the vehicle body and located above the through opening, and a stopper matching the through opening is fixed to the bottom of the protective plate.

[0013] Preferably, a retaining ring is provided at one end of the first roller and one end of the second roller, and a protective layer is provided on the outer side of the first roller.

[0014] Preferably, limiting plates are evenly arranged on the outer side of the limiting disk, and a wear-resistant layer is provided on the limiting plates.

[0015] Preferably, a protective ring is provided on the outer side of the second spiral tube, and anti-slip grooves are provided on the outer side of the protective ring.

[0016] The beneficial effects of the utility model are:

[0017] The utility model provides a fast reeling fire truck. Through the coordinated use of the vehicle body, mounting seat, electric push rod, movable plate, fixing column, rotating pipe, motor, rotating shaft, mounting plate, fixing rod, fixing plate, screw tube 1, rotating roller 1 and rotating roller 2, the fire hose can be partially lifted up to make it off the ground when reeling, thereby reducing the friction damage of the fire hose caused by winding and dragging. The fire hose is suspended in the air to facilitate the stretching and flattening of the pipe body. The suspension plus manual auxiliary adjustment can reduce the workload of laying the fire hose in advance, thereby improving the efficiency of reeling and improving the protection effect of the fire hose.

[0018] By cooperating with the movable rod, the third screw tube and the sliding hole, the distance between the second roller and the first roller can be adjusted according to the thickness of the fire pipe, and then the fire pipes of different thicknesses can be squeezed to limit the position, so that the moisture inside the fire pipe can be squeezed out without manual squeezing, thereby improving the working efficiency of the fast retracting fire truck;

[0019] By cooperating with the limit plate, the screw and the second screw tube, the limit plate is turned toward the limit plate or in the opposite direction according to the width of the fire pipe, so that the limit plate moves to the right or to the left, and the distance between the limit plate and the fixed plate is adjusted to adapt to fire pipes of different widths, thereby improving the applicability of the fast retracting fire truck.

One end of the movable plate 4 is rotatably connected to a roller 17, and a roller 2 18 is provided at one end of the movable plate 4 and on one side of the roller 17. A retaining ring is provided at one end of the roller 17 and one end of the roller 2 18. The retaining ring limits one side of the fire pipe to prevent the fire pipe from being dislocated and dislocated, and a protective layer is provided on the outside of the roller 17 to protect the roller 17. A mounting mechanism 12 is provided between the roller 2 18 and the movable plate 4, and a through opening 6 is provided on the top of the vehicle body 1, which is aligned with the movable plate 4 up and down.

[0028] Specifically, one end of the fire hose near the pipe head or the middle pipe body position after the fire hose is folded in half is placed between the fixing rods 10, and the fire hose head is limited by the two fixing rods 10. Then the fixing rod 10 is inserted into the mounting plate 9 and threadedly fixed by the screw 13. Then the pipe body of the fire hose is flattened and clamped between the second roller 18 and the first roller 17. The electric push rod 3 is started, and the telescopic end of the electric push rod 3 pushes the hinge block 5 and the movable plate 4 upward, so that the movable plate 4 flips upward counterclockwise until the electric push rod 3 is started. The movable push rod 3 is extended to the longest position and the end of the movable plate 4 is at the highest position from the ground. The movable plate 4 simultaneously drives the fixed rod 10 and the fire hose head to move up, so that part of the fire hose body is off the ground and suspended in the air. The motor 7 is started to drive the rotating shaft 8 and the fixed rod 10 to rotate until the winding work of the fire hose on the outside of the fixed rod 10 is completed. The screw 13 can be loosened to remove the fixed rod 10 together with the fire hose.
