Description
Technical Field
[0001] The utility model relates to the technical field of fire-fighting auxiliary equipment, in particular to a mobile fire-fighting hose truck. Background Art
[0002] Fire trucks and drainage trucks need to carry and lay a large number of fire hoses when they go out to perform fire extinguishing and drainage tasks. Fire hoses are hoses used to transport flame-retardant liquids such as high-pressure water or foam. Traditional fire hoses have rubber lining and the outer surface is wrapped with linen woven fabric. Mobile fire hose trucks are tools for transporting fire hoses.
[0003] When laying the water hose on most of the existing mobile fire hose trucks, firefighters are required to manually pull the front end of the water hose so that the reel rotates when the water hose is stressed and the water hose is unfolded. The laying efficiency is low, the firefighters' physical strength is consumed to a certain extent, and the water hose is easily damaged when stressed. Utility Model Content
[0004] The purpose of the utility model is to provide a mobile fire hose truck to solve the problems raised in the above background technology.

[0006] Preferably, one end of the bearing is sleeved on the outer surface of a through column extending from one end of the interface reel, so that the hose reel can rotate with the center of the through column as the center of the circle, and the fire hose can be reeled in and stored, which is convenient to use.
[0007] Preferably, the bottom end surfaces of the two tripods are commonly connected to the top end surface of the plate, and the tripod supports the hose reel and the interface reel to ensure the stability of the mobile fire hose truck.
[0008] Preferably, a pull rod is provided at the edge of one side of the top of the presentation board, and two triangular bearings are provided at both ends of the bottom of the presentation board. The triangular parts of the two triangular bearings are provided with rollers. When moving the mobile fire hose truck, the pull rod can be pulled. When moving, the rollers provided at the triangular parts of any two triangular bearings are in contact with the ground. When encountering obstacles such as steps or stones, the triangular bearings rotate to cause the rollers to roll over the obstacles. There is no need to move the mobile fire hose truck, thereby increasing the moving speed.
[0009] Preferably, a tripod is extended from one end of the support column, and a secondary pulley is provided at the extended end of the support column. A motor is detachably installed at the top edge of the presentation plate, and a main pulley is provided at one end of the motor. The outer surfaces of the main pulley and the secondary pulley are commonly connected with a crawler track. The motor drives the secondary pulley to rotate through the main pulley and the crawler track, so that the water hose reel rotates, and the water hose is automatically retracted or laid, thereby improving the efficiency of laying or storing the water hose.
[0010] Preferably, a secondary pulley extends from one end of the through column, and a clamping column is provided at the extended end of the through column. A rotating handle is sleeved on the outer surface of the clamping column, and a socket matched with the outer surface of the clamping column is provided inside the connection position between one end of the rotating handle and the clamping column. In special fire situations, when the motor cannot be used, the rotating handle can be inserted into the outer surface of the clamping column to assist in rotating the water hose reel, which saves effort.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. This mobile fire hose truck drives the secondary pulley to rotate through the motor, so that the hose reel rotates, and the hose is unfolded for laying. When the hose is stored after the rescue is completed, the hose interface is passed through the bottom of the hose reel, and then the joint is turned over, and the interface is placed on the top of the interface reel. Then the hose reel rotates, and the interface reel remains stationary, and the hose is pulled and reeled on the outer surface of the hose reel. The storage and laying efficiency is high, and the efficiency is improved. When laying, there is no need to pull the front end of the hose, which avoids damage caused by pulling the hose, and at the same time reduces the physical consumption of firefighters.
[0013] 2. The mobile fire hose truck contacts the ground through the rollers arranged at the triangular part of the triangular bearing, so that the fire hose truck can run smoothly. When encountering obstacles such as steps or stones, the triangular bearing rotates to make the rollers roll over to climb over the obstacles. There is no need to move the mobile fire hose truck, which increases the moving speed. BRIEF DESCRIPTION OF THE DRAWINGS

When storing the fire hose, the hose interface is passed through the bottom of the hose reel 9, and then the joint is turned over, and the interface is placed on the top of the interface reel 15. Then, when the hose reel 9 rotates, the hose will be pulled and reeled in The outer surface of the water hose reel 9, the center position of the water hose offset disk 6 and the interface reel 15 are jointly fixedly connected with a through column 16, and both ends of the through column 16 extend out of one end of the water hose offset disk 6 and the interface reel 15, and a bearing 14 is arranged at the center position of the water hose reel 9 to ensure that the water hose reel 9 can rotate and the interface reel 15 remains stationary, and a support column 10 is arranged at the front center position of the water hose reel 9, and the outer surfaces of the support column 10 and the through column 16 are both provided with a tripod 8, which has a supporting effect to ensure the stability of the mobile fire hose truck.
[0021] Specifically, one end of the bearing 14 is sleeved on the outer surface of a through column 16 extending from one end of the interface reel 15, so that the hose reel 9 can rotate around the center of the through column 16, and the fire hose can be reeled in for easy use.
[0022] Furthermore, the bottom end surfaces of the two tripods 8 are commonly connected to the top end surface of the presentation board 1, and the tripods 8 support the hose reel 9 and the interface reel 15 to ensure the stability of the mobile fire hose truck.
[0023] Furthermore, a pull rod 7 is provided at the edge of one side of the top of the presentation board 1, and two triangular bearings 2 are provided at both ends of the bottom of the presentation board 1.

There is no need to move the mobile fire hose truck, which increases the moving speed. When it is necessary to lay the fire hose, the hose connector is installed on the fire hose truck or the fire hydrant, and then the head end of the hose is pulled, and the motor 4 is turned on. The motor 4 drives the secondary pulley 12 to rotate through the main pulley 5 and the crawler track 11, so that The water hose reel 9 rotates to unfold the water hose for laying. In special fire situations, when the motor 4 cannot be used, the rotating handle 18 can be plugged into the outer surface of the clamping column 17 to assist in rotating the water hose reel 9, which saves effort. When storing the water hose after the rescue is completed, the water hose interface is passed through the bottom of the water hose reel 9, and then the joint is flipped over, and the interface is placed on the top of the interface reel 15. Then the water hose reel 9 rotates, and the interface reel 15 remains stationary, and the water hose is pulled and reeled onto the outer surface of the water hose reel 9.
