Description

Technical Field

[0001] The utility model belongs to the technical field of fire hoses, and in particular relates to a fire hydrant hose hole repairing device. Background Art

[0002] At present, fire hydrant hoses are flexible pipes used to transport high-pressure water. After long-term use, the contact area between the fire hydrant hose and the ground will be worn. In severe cases, holes may even appear in the fire hydrant hose, resulting in a shortened range of the water jet during fire extinguishing, thereby affecting firefighting and rescue work. The damaged fire hose can be repaired before use. However, since the existing fire hydrant hose is a flexible pipe, the repair effect of the hose is poor, and it is impossible to determine whether the repair strength requirements are met after repair. Therefore, a fire hydrant hose hole repair device with good repair effect is urgently needed. Utility Model Content

[0014] Compared with the prior art, the advantages and positive effects of the present invention are:

[0015] (1) The two ends of the support spring in the length direction are detachably connected to the first sealing cylinder and the second sealing cylinder respectively. The fire hydrant hose is shaped by the support spring, and the support effect is good, which is convenient for repairing the fire hydrant hose.

[0016] (2) The inflation tube is connected to the air inlet, and gas is injected through the inflation tube to perform pressure testing on the specific position after repair. The test pressure is the squeezing force applied by the inner side of the fire hydrant hose, which can better simulate the actual effect.

The positioning bolts can be threadedly connected to different threaded holes, thereby changing the maximum stretching length of the support spring when the first sliding positioning part and the second sliding positioning part are slidably connected, thereby replacing different support springs for different gaps to be repaired, and having a wide range of applications;

[0019] (5) A first guide chamfer is provided at one end of the first sealing cylinder away from the support spring, and a second guide chamfer is provided at one end of the second sealing cylinder close to the support spring. The first guide chamfer and the second guide chamfer serve as guides to facilitate assembly;

[0020] (6) Both the first sliding body and the second sliding body are rectangular frames. The first sliding body and the second sliding body will not rotate relative to each other during relative sliding, thereby avoiding generating a torsional force on the support spring and damaging the spring.
