Description

Technical Field

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

[0002] Fire hoses are crucial flexible conduits used in firefighting operations to transport high-pressure water or foam extinguishing agents. They are typically made of wear-resistant and pressure-resistant synthetic fibers (such as polyester) or rubber composites, with an outer polyurethane coating to enhance their anti-aging properties. The design of fire hoses must meet stringent fire and explosion-proof standards, and they can withstand working pressures of 1.0 MPa or higher, with some high-pressure models even reaching 4.0 MPa. When fire hoses are bonded at high temperatures, they require fixing devices to secure the structure.

[0003] For example, patent announcement number CN216032584U discloses a high-temperature bonding device for manufacturing fire hoses, including a base, a support plate connected to the front end of the top of the base, a support connected to the rear end of the top of the base, a connecting mechanism on the top of the support, a sealing mechanism between the support plates and above the connecting mechanism, and a fixing mechanism on the top of the base and in front of the support. The sealing mechanism includes a fixing box, a cylinder, a connecting rod, a turntable, a sector gear, a rack, and a sealing clamp. The fixing box is connected between the support plates, and the cylinder is connected to the top of the fixing box. The beneficial effects are: this utility model, by setting a sealing mechanism, seals the interface of the fire hose, resulting in a good sealing effect. Furthermore, by setting a fixing mechanism, the end of the hose is fixed and further sealed, preventing the end of the hose from being flattened and deformed, and further improving the sealing performance.

[0004] In the above-mentioned technology, the fire hose joint is clamped and fixed to the sleeve pipe by two sealing clamps. However, the sealing clamps and sleeve pipe are of fixed size, which is not convenient for clamping and fixing fire hose joints of different diameters, and the applicability is low. Therefore, the market urgently needs to develop a fire hose high-temperature adhesive joint fixing device to help people solve the existing problems. Utility Model Content

[0005] The purpose of this utility model is to provide a high-temperature bonding joint fixing device for fire hoses, so as to solve the problem mentioned in the background art that the fire hose joint is fixed to the sleeve pipe by two sealing clamps, but the sealing clamps and sleeve pipe are of fixed size, which is not convenient for clamping and fixing fire hose joints of different diameters and has low applicability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature adhesive joint fixing device for fire hoses, comprising a support platform, a support column fixedly connected to one side of the upper surface of the support platform, a support pipe fixedly connected to the middle of one side of the support column, an annular pressure airbag sleeved on the outside of the support pipe, and a tightening strap provided on both sides of the middle of the annular pressure airbag. A first support frame is fixedly connected to the upper surface of the support platform and to the front end of the annular pressure airbag. A first fixing plate is fixedly connected to the upper end of the first support frame. A hydraulic rod is fixedly connected to the middle of the front end of the first fixing plate. The rear end of the telescopic end of the hydraulic rod extends out of the rear end of the first fixing plate and is fixedly connected to a pulling plate.

[0007] Preferably, a steam pipe is fixedly connected to the middle of the support column and the support tube, and the annular pressure bladder is fixedly connected to the outer wall of the support tube.

An air supply pipe is fixedly connected to the outer side of the upper vent, and an air pump is fixedly connected to the end of the air supply pipe away from the vent after passing through the support column.

[0009] Preferably, an exhaust pipe is fixedly connected to the outside of the lower vent, and an exhaust valve is fixedly connected to the end of the exhaust pipe away from the vent after passing through the support column.

[0010] Preferably, one end of each of the two straps passes through the lower end of the annular pressure airbag and is fixedly connected to the front end face of the second fixing plate, and the other end of each strap passes through the lower end of the annular pressure airbag and is fixedly connected to the rear end face of the pulling plate.

[0011] Preferably, guide tubes are fixedly connected to both sides of the middle portion of the first fixed plate, and guide rods are fixedly connected to both sides of the middle portion of the rear end face of the pull plate.

[0012] Preferably, the front ends of the two guide rods pass through the interior of the two guide tubes and extend out of the front end face of the first fixing plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) In this utility model, by setting an inflatable annular pressure airbag structure, it can adapt to fire hose joints of different diameters and achieve flexible fixation by adjusting air pressure, thus avoiding the size limitation problem of traditional rigid clamps and significantly improving the applicability and versatility of the device.

[0015] (2) In this utility model, a double fixing design is adopted, with the internal support provided by an airbag expansion and the external binding by a strapping band, forming a more stable fixing effect, effectively preventing the hose joint from shifting or deforming during the high-temperature bonding process, and ensuring the bonding quality.

[0016] (3) In this utility model, the precise control of the binding strap is achieved by hydraulic drive and guide mechanism. Combined with the air pressure adjustment mechanism, the entire fixing process is simple, stable and reliable. At the same time, the integrated design of steam pipe facilitates the simultaneous high-temperature bonding operation, which improves production efficiency. Attached Figure Description

[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 fixing device for fire hoses, comprising a support platform 1, a support column 2 fixedly connected to one side of the upper end face of the support platform 1, a support pipe 201 fixedly connected to the middle of one side of the support column 2, an annular pressure airbag 203 sleeved on the outside of the support pipe 201, and vents 204 provided at both the upper and lower ends of the middle of the side end face of the annular pressure airbag 203 adjacent to the support column 2, an air supply pipe 205 fixedly connected to the outside of the upper vent 204, and the end of the air supply pipe 205 away from the vent 204 passing through the support column 201. An air pump 206 is fixedly connected to the support column 2. An exhaust pipe 207 is fixedly connected to the outside of the lower vent 204. The end of the exhaust pipe 207 away from the vent 204 passes through the support column 2 and is fixedly connected to an exhaust valve 208. The fire hose connector is put into the outside of the annular pressure airbag 203. The air pump 206 pressurizes and supplies air to the inside of the annular pressure airbag 203 through the air supply pipe 205, causing the annular pressure airbag 203 to expand and contact the inner wall of the fire hose connector. When the annular pressure airbag 203 continues to expand, it opens and fixes the fire hose connector and achieves a seal.

[0024] Please see Figure 1 and Figure 3 Both sides of the annular pressure airbag 203 are provided with tightening straps 3. A first support frame 4 is fixedly connected to the upper end of the support platform 1 and the front end of the annular pressure airbag 203. A first fixing plate 401 is fixedly connected to the upper end of the first support frame 4. A hydraulic rod 403 is fixedly connected to the middle of the front end of the first fixing plate 401. The rear end of the telescopic end of the hydraulic rod 403 extends out of the rear end of the first fixing plate 401 and is fixedly connected to a pulling plate 404. One end of each of the two tightening straps 3 passes through the lower end of the annular pressure airbag 203 and is connected to the second fixing plate 50. 1. The front end is fixedly connected. The other ends of the two tie straps 3 pass through the lower end of the annular pressure airbag 203 and are fixedly connected to the rear end of the pull plate 404. When the annular pressure airbag 203 expands and opens and fixes the fire hose joint, the hydraulic rod 403 pulls one end of the two tie straps 3 to move, so that the tie straps 3 are gathered and bound to the outside of the fire hose joint. The expansion of the two annular pressure airbags 203 supports the fire hose joint and the two tie straps 3 are gathered and fixed to make the fire hose joint stably fixed on the annular pressure airbag 203.

[0025] Please see Figure 2 A steam pipe 202 is fixedly connected to the middle of the support column 2 and the support pipe 201. The annular pressure airbag 203 is fixedly connected to the outer wall of the support pipe 201. High-temperature steam is delivered to the interior of the fire hose through the steam pipe 202 to achieve high-temperature bonding.

[0026] Please see Figure 3 and Figure 4The first fixed plate 401 has guide tubes 402 fixedly connected to both sides of the middle part, and the pull plate 404 has guide rods 405 fixedly connected to both sides of the middle part of the rear end face. The front ends of the two guide rods 405 pass through the interior of the two guide tubes 402 and extend out of the front end face of the first fixed plate 401. When the pull plate 404 moves, it is guided by sliding along the interior of the guide tubes 402 through the guide rods 405.

[0027] Working Principle: In use, first, the fire hose connector is fitted onto the annular pressure bladder 203 outside the support pipe 201. The air pump 206 is started, and air is pumped into the annular pressure bladder 203 through the air supply pipe 205, causing the bladder to expand and tightly adhere to the inner wall of the hose connector, achieving radial fixation and sealing. Simultaneously, the hydraulic rod 403 pushes the pulling plate 404 backward, and the tightening straps 3 circumferentially bind the hose connector, forming a double fixation. After fixation, high-temperature steam is introduced through the steam pipe 202 to heat the bonded area. The exhaust valve 208 adjusts the internal pressure of the bladder. After the bonding operation is completed, the tension of the tightening straps 3 is released first, and then the gas inside the bladder is discharged through the exhaust valve 208 to remove the hose connector. The cooperation between the guide rod 405 and the guide pipe 402 ensures smooth movement of the pulling plate 404. The entire device achieves adaptive fixation of hose connectors with different pipe diameters through air pressure and mechanical linkage.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. 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. No reference numerals in the claims should be construed as limiting the scope of the claims.
