Description

Technical Field

[0001] This utility model relates to the field of fire hose testing, specifically a fire hose high-temperature adhesive joint testing device. Background Technology

[0002] Fire hoses are crucial flexible conduits in fire extinguishing systems used to transport high-pressure water or foam extinguishing agents. They are typically made of abrasion-resistant and pressure-resistant synthetic fibers (such as polyester) or rubber materials, with an outer polyurethane or PVC coating to enhance waterproofing and corrosion resistance. Standard lengths are generally 20 or 25 meters, with diameters ranging from 25 mm to 150 mm. Both ends are equipped with metal or plastic quick-connect fittings for easy connection to fire hydrants, pumps, or spray guns. Fire hoses must possess high-temperature resistance and burst-resistant properties, and their visibility in dark environments can be improved with fluorescent strips or reflective tape. After high-temperature bonding, fire hoses require leak detection using a leak testing device.

[0003] For example, authorization announcement number CN220960456U discloses a fire hose detection device, belonging to the field of fire hose technology. This fire hose detection device includes a detection component and a rotating component. A first positioning plate and a second positioning plate are used to better fix the fire hose to be tested. An air pump can inflate the fire hose through the first positioning plate, allowing the leak detection strip to adhere better to the fire hose. If leaks occur on different sides of the fire hose, rotating the first and second handles simultaneously will rotate the first and second positioning plates, thus rotating the fire hose and facilitating the adhesion of the leak detection strip to different sides. This allows for more comprehensive and accurate detection of leaks. Furthermore, the device facilitates flipping the fire hose for subsequent leak detection strip adhesion, reducing labor and improving practicality.

[0004] The aforementioned detection device uses a compression ring and a snap ring to fix both ends of the fire hose. However, the size of the compression ring and snap ring cannot be adjusted, making it inconvenient to detect fire hoses of different diameters. Therefore, there is an urgent market need to develop a high-temperature adhesive joint detection device for fire hoses to help people solve the existing problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4This utility model provides an embodiment of a high-temperature adhesive joint detection device for fire hoses, comprising a support platform 1. A first cylindrical support 101 and a second cylindrical support 102 are fixedly connected to the front and rear ends of one side of the upper surface of the support platform 1, respectively. A connecting post 2 is connected to the middle of one side end of both the first cylindrical support 101 and the second cylindrical support 102. A sealing strap 3 is spirally wound around the middle of the connecting post 2. One end of the sealing strap 3 is fixedly connected to the upper surface of the support platform 1 via a fixing post 301, and the other end of the sealing strap 3 is connected to the upper surface of the support platform 1 via a hydraulic rod 302. The lower end of the hydraulic rod 302 is fixedly connected to the upper surface of the support platform 1, and the upper end of the telescopic end of the upper surface of the support platform 1 is fixedly connected to the sealing strap 3. A conveying pipe 5 is jointly provided in the middle of the first cylindrical support 101 and the connecting post 2 on one side. A pressure detection device 6 is fixedly connected to the middle of the side end of the second cylindrical support 102 away from the connecting post 2. The conveying pipe 5 is connected to the first cylindrical support 101. The support members 101 are fixedly connected. One end of the delivery pipe 5 extends from the end face of the first cylindrical support member 101 away from the sleeve post 2 and is fixedly connected to an air pump 501. A detection probe 601 is fixedly connected to the middle of one side of the pressure detection device 6. The detection end of the detection probe 601 passes through the middle of the second cylindrical support member 102 and the sleeve post 2 on one side and extends out of the sleeve post 2. The two ends of the fire hose to be tested are respectively put onto the two sleeve posts 2. The hydraulic rod 302 pulls one end of the sealing strap 3, so that the spiral winding part of the sealing strap 3 is tightened on the fire hose. The fire hose is tightened and sealed on the sleeve post 2 by the gradual tightening of the sealing strap 3, so that the two ends of the fire hose are fixed and sealed. Air is injected into one end of the fire hose by the air pump 501 to expand the fire hose. When the fire hose is fully expanded, the air supply is stopped. The pressure detection device 6 detects whether the internal air pressure of the fire hose is stable through the detection probe 601, so as to realize the air leakage detection after the fire hose is bonded.

[0024] Please see Figure 1 A connecting ring 201 is fixedly connected to one side of the sleeve post 2. The connecting rings 201 on one side of the two sleeve posts 2 are respectively fixedly connected to the end face of the first cylindrical support 101 and the second cylindrical support 102 by multiple bolts 202. By removing the multiple bolts 202, the sleeve post 2 can be separated from the first cylindrical support 101 or the second cylindrical support 102, which facilitates the replacement of sleeve posts 2 with different diameters according to the inner diameter of the fire hose to be tested, so as to realize the testing of fire hoses with different inner diameters.

[0025] Please see Figure 2 and Figure 4A connecting rod 4 and a fixing clamp 401 are respectively provided at the upper and lower ends of one side of the outer wall of the sleeve post 2. The front and rear ends of the connecting rod 4 and the fixing clamp 401 are fixedly connected by guide posts 402. A lifting clamp 405 is connected to both guide posts 402 and the upper end of the sleeve post 2. An internal threaded tube 403 is fixedly connected to the middle of the connecting rod 4. A screw 404 is threadedly connected to the inside of the internal threaded tube 403. The upper end of the screw 404 extends out of the upper end of the internal threaded tube 403 and is fixedly connected to a knob. The lower end of the screw 404 extends out of the lower end of the internal threaded tube 403 and is connected to the middle of the upper end face of the lifting clamp 405 through a rotating seat 406. Anti-detachment grooves 203 are provided at both the top and bottom ends of one side of the wall. When the fire hose is sleeved on the connecting post 2 and fixed and sealed by the sealing strap 3, the screw 404 is rotated by rotating the knob. The screw 404 drives the lifting clamp 405 to descend through the threaded connection with the internal threaded pipe 403, thereby causing the fixed clamp 401 and the lifting clamp 405 to move relative to each other. When the fixed clamp 401 and the lifting clamp 405 move relative to each other, they respectively clamp the top and bottom ends of the fire hose and press the clamping position into the anti-detachment grooves 203 at both the top and bottom ends of the outer wall of the connecting post 2 for fixation, so as to prevent the end of the fire hose from slipping off the connecting post 2 when it is inflated.

[0026] Working Principle: In use, first select a suitable connecting post 2 according to the inner diameter of the fire hose to be tested. Fix the connecting ring 201 of the connecting post 2 to the first cylindrical support 101 and the second cylindrical support 102 respectively using bolts 202. After fitting both ends of the fire hose into the two connecting posts 2 respectively, activate the hydraulic rod 302 to retract, causing the sealing strap 3 to tighten spirally, forming a sealed connection between the hose end and the connecting post 2. Then, rotate the knob to drive the screw 404 to rotate, causing the lifting clamp 405 to move downwards through threaded transmission, cooperating with the fixed clamp 401 to press the hose end into the anti-detachment groove 203 for fixation. Start the air pump 501 to inflate the hose through the delivery pipe 5. After full expansion, stop inflating. The pressure detection device 6 monitors the internal air pressure changes of the hose in real time through the detection probe 601. If the air pressure remains stable, it indicates a good seal at the joint; if the air pressure drops, it indicates a leak, requiring repair of the high-temperature bonded joint. This device enables rapid detection of fire hose joints of different specifications through replaceable sockets and an adaptive sealing structure.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
