Description

Technical Field

[0001] This utility model relates to the field of fire hose technology, specifically a fire hose pressure resistance testing device. Background Technology

[0002] Fire hoses in building fire hydrants may develop cracks if left unused for a long time, causing them to fail when used. Therefore, it is necessary to regularly test the pressure resistance of the hoses.

[0003] A search revealed Chinese Patent Publication No. CN 222188688 U, published on December 17, 2024, which discloses a pressure resistance testing device for building fire hoses. The document states that "the testing chamber is a rectangular open box, on which a water hose to be tested is placed, filled with water and closed at both ends, and several upper pressure rollers are provided above the water hose." When the device moves to apply pressure, the water hose will be worn, and twisting or displacement will occur during the process of moving to apply pressure. In view of this, in-depth research was conducted to address the above problems, leading to this case. Utility Model Content

[0004] The purpose of this invention is to provide a fire hose pressure resistance testing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fire hose pressure resistance testing device, comprising a base, slots, and a testing structure, wherein slots are provided on both sides of the base, and a testing structure is installed on the outer side of the base;

[0006] The detection structure includes a slide table, a slider, and a first base plate. Slide tables are installed on both sides of the outer wall of the base, sliders are installed on both sides of the slide tables, and the first base plate is installed above the sliders. An electric cylinder is installed above the first base plate, and a plate is installed between the two electric cylinders. A groove is provided on the inner side of the plate, and a first fixing rod is provided on the inner side of the groove. The two sides of the first fixing rod are connected to the plate via a first bearing. A first protective pad is installed on the outer wall of the first fixing rod. The outer wall of the electric cylinder is connected to a connecting plate via a connecting rod. The two connecting plates are connected to the two sides of a second fixing rod via a second bearing. A second protective pad is installed on the outer wall of the second fixing rod. A second base plate is installed below the connecting plate, and an electric housing is installed below the second base plate. The electric housing is installed above a track, which is installed on both sides inside the base.

[0007] Preferably, the base and the slide are fixedly connected, and the slide and the slider are slidably connected.

[0008] Preferably, the first base plate is fixedly connected to the upper part of the slider and the lower part of the electric cylinder, and the plate body and the electric cylinder are arranged perpendicular to each other.

[0009] Preferably, the plate and the groove are integrally formed, and the grooves are correspondingly formed with the first fixing rod and the first protective pad.

[0010] Preferably, the first fixing rod and the first bearing are rotatably connected, and the middle position of the first fixing rod and the middle position of the second fixing rod are on the same horizontal line.

[0011] Preferably, the first fixing rod and the first protective pad are tightly fitted together, and the second fixing rod and the second protective pad are tightly fitted together.

[0012] Preferably, the second fixing rod and the second bearing are rotatably connected, and the connecting plates are fixedly connected to the connecting rod and the second base plate.

[0013] Preferably, the outer side of the connecting rod is fixedly connected to the outer wall of the electric cylinder.

[0014] Preferably, the second base plate is fixedly connected to the electric housing, and the electric housing is slidably connected to the track.

[0015] Preferably, the track and the slide are arranged parallel to each other.

[0016] Compared with existing technologies, the beneficial effects of this utility model are:

[0017] By setting up a slide table, slider, and first base plate, the two ends of the fire hose to be tested are respectively inserted into the slots to ensure stable fixation of the hose. The electric cylinder pushes the plate body downward, so that the first and second fixing rods apply radial pressure to the hose, and the first and second protective pads are in contact with the hose to prevent damage to the hose surface during the test. The electric housing is activated to move along the track, and the position is adjusted by the electric cylinder connected by the connecting rod. The electric cylinder drives the slider connected to the first base plate to move on the slide table to adjust the pressure application position and ensure that the force is evenly distributed on all parts of the hose. The first and second bearings allow the fixing rods to rotate, preventing the hose from twisting or shifting due to friction. The pressure is precisely controlled by the electric cylinder to simulate different water pressure environments. The hose is held at the set pressure for a certain period of time, and it is observed whether there is any cracking, leakage, or deformation. If the hose can withstand the specified pressure and there are no abnormalities, it is judged as qualified; otherwise, it is judged as unqualified. After the test is completed, the electric cylinder retracts, releasing the fixing rods to facilitate the removal of the hose, and the slide table and slider are adjusted to prepare for the next round of testing.
