Description
Technical Field
[0001] This invention belongs to the field of fire protection equipment technology, and in particular relates to a manufacturing process for wear-resistant fire hoses. Background Technology
[0002] Fire hoses are flexible tubes used to transport high-pressure water or flame-retardant liquids such as foam. Both ends of a fire hose have metal connectors, which can be connected to another hose to extend the distance or to a nozzle to increase the liquid spray pressure. When connecting the flexible part of the fire hose to the metal connector part, a high-temperature bonding process is often required, which necessitates the use of appropriate equipment.
[0003] Utility model patent CN217258517U discloses a high-temperature bonding machine for connecting fire hoses, comprising a load-bearing platform, a first telescopic column, a heating frame, a pressure box, and a second telescopic column. Load-bearing blocks are provided at the four corners of the lower end of the load-bearing platform. A support column is provided at the front end of one side of the load-bearing platform. A surrounding plate is provided at the upper end of the load-bearing platform, and a load-bearing plate is provided at the upper end of the surrounding plate. The first telescopic column is provided on the inner surface of one side of the surrounding plate. A bonding block is provided at the telescopic end of the first telescopic column, and the heating frame is provided inside the bonding block. A support block is provided below the first telescopic column. The pressure box is provided at the upper end of the load-bearing plate, and the second telescopic column is provided inside the upper end of the pressure box. The device has a simple structure, is easy to use, and most of the components are easy to disassemble, facilitating disassembly and repair in case of malfunction.
[0004] However, the above-mentioned device has the following technical problems in actual use: 1. The above-mentioned device covers the fire hose on the outside of the adhesive block and uses the heating element on the adhesive block to heat the fire hose, thereby facilitating the bonding and installation of the joint. However, in actual use, the inner diameter of the fire hose is usually matched with the diameter of the joint end. The adhesive block of the above-mentioned device lacks a device to support the end of the fire hose, which makes it difficult to stably cover the end of the fire hose on the outside of the joint. It is not easy to ensure the installation of the joint during the covering process.
[0005] Second, in addition, the adhesive block in the above-mentioned device has a conical structure, and the diameter of its pointed end is smaller than its middle diameter. When the fire hose is sleeved on the outside of the adhesive block, the end of the fire hose and the pointed end of the adhesive block are level. However, due to the conical shape of the end of the adhesive block, the diameter of the pointed end is smaller than the inner diameter of the fire hose. As a result, the fire hose will droop on the adhesive block, and therefore cannot effectively open the fire hose, and cannot ensure that the end of the joint can be stably inserted into the end of the fire hose. Summary of the Invention
[0006] This invention provides a manufacturing process for wear-resistant fire hoses, aiming to solve the problems mentioned in the background art.
[0007] This invention is implemented as follows: a manufacturing process for a wear-resistant fire hose includes: a base, on which a clamping mechanism is movably connected, and the end of a fire hose to be processed is fixedly installed within the clamping mechanism. A support mechanism is also movably installed on the base to one side of the clamping mechanism, with its end portion inserted into the end of the fire hose. The clamping mechanism has: an annular seat, on which multiple clamping components are distributed at equal angles. Each clamping component is slidably connected to the annular seat, and the end of each clamping component near the center of the annular seat is used to clamp the fire hose. An anti-displacement component is also provided on the outer peripheral wall of the annular seat to one side of the clamping component, and the anti-displacement component and the clamping component are detachably connected. The support mechanism has: an inner tube heating component, which is rotatably connected to one side of the annular seat, and the inner tube heating component is also provided with an adjustment component for adjusting the... The centripetal distance of the inner tube heating assembly, each clamping assembly is also provided with a transmission assembly, the transmission assembly is mounted on the inner tube heating assembly, and the base is also provided with a first moving assembly and a second moving assembly for controlling the relative movement of the clamping mechanism and the support mechanism; in this scheme, the device places the end of the fire hose that needs to be loaded with the joint between multiple arc-shaped heating plates, and uses the clamping assembly to clamp the fire hose from multiple angles, so that the end of the fire hose is in contact with multiple arc-shaped heating plates. When the inner tube heating assembly is working, it can heat the fire hose end from both the inside and outside sides at the same time with the multiple arc-shaped heating plates. At the same time, the adjusting assembly will also control the inner heating tube to move from the center of the rotating plate to the edge, increasing the diameter of the inner heating tube when rotating. The connecting rod, in conjunction with the transmission assembly, controls multiple sets of clamping assemblies to gradually open the fire hose end, so as to facilitate the subsequent expansion of the fire hose end so that it can wrap around the outside of the joint end.
[0008] In this device, the inner heating tube is inserted into the end of the fire hose. The first motor controls the rotation of the inner heating tube, while the second motor, in conjunction with the first screw, controls the movement of the inner heating tube. The inner heating tube moves from the center of the rotating plate to the edge, thereby increasing the diameter range of the inner heating tube during rotation. The connecting rod set on one side of the inner heating tube pushes multiple transmission components to gradually move away from the fire hose. At the same time, the transmission components drive the clamping components to move, stretching the end of the fire hose outward, thus expanding the fire hose port.
[0009] It should be noted that during one rotation of the connecting rod in this device, it will sequentially contact each transmission component. Each transmission component will gradually pull the fire hose port to expand it through the clamping component, avoiding the problem of reduced toughness or breakage of the fire hose port caused by simultaneous one-time stretching.
[0010] In addition, in this device, after the support mechanism opens the fire hose port to a certain extent, the second moving component controls the support mechanism to move away from the annular seat. The person (with the help of external tools or devices) can place the connector to be loaded inside the fire hose port. The fire hose is reset by separating the anti-displacement component and the clamping component, thereby completing the assembly of the connector. This assembly method can ensure that the fire hose is in the supported state when the connector is assembled. On the other hand, the arc heating plate is still heating the fire hose when the connector is placed, avoiding the fire hose from loosening due to loss of high temperature, which would affect the normal assembly of the connector.
[0011] Preferably, the clamping assembly includes: a sliding groove formed on the annular seat, a sliding rod slidably connected in the sliding groove, an arc-shaped heating plate fixedly installed at the bottom end of the sliding rod, the arc-shaped heating plate conforming to the outer surface of the fire hose, a clamping groove formed on the side wall of the sliding rod above the arc-shaped heating plate, a sliding rod fixedly installed in the clamping groove, a connecting plate slidably connected to the clamping groove on the sliding rod, the connecting plate being L-shaped, having a horizontal section slidably connected to the clamping groove and a vertical section fixedly connected to the end of the horizontal section, the vertical section extending to the side of the arc-shaped heating plate away from the sliding rod, and a clamping plate fixedly installed at the end of the vertical section, the clamping plate and the horizontal section being parallel to each other. A first spring is also sleeved on the sliding rod near the side of the arc-shaped heating plate on the horizontal section. In this scheme, sliding grooves are opened at equal angles on the annular seat, and a sliding rod is slidably connected in each sliding groove. An arc-shaped heating plate is fixedly installed on the end of the sliding rod near the center of the annular seat. The arc-shaped heating plate is electrically connected to an external power source. When the power is turned on, the arc-shaped heating plate heats up and heats the fire hose attached to its inner arc surface. A clamping groove is opened on the sliding rod above the arc-shaped heating plate. When the first spring is in a free and extended state, the horizontal section is located at the end of the clamping groove away from the arc-shaped heating plate. At the same time, the vertical section pulls the clamping plate to adhere to the inner arc surface of the arc-shaped heating plate, thereby clamping and fixing the fire hose.
[0012] It should be noted that the arc-shaped heating plate and the clamping plate are located at both ends of the fire hose.
[0013] When the horizontal section slides along the clamping groove toward the arc-shaped heating plate, it will compress the first spring and simultaneously control the clamping plate to move away from the arc-shaped heating plate through the vertical section, thus facilitating the loading and unloading of fire hoses.
[0014] Preferably, the anti-displacement assembly includes: a plurality of limiting protrusions fixedly installed at equal intervals along the height of the side wall of the sliding rod; each limiting protrusion has a first inclined surface extending towards its top wall on the side wall away from the sliding rod; a fixing seat is also fixedly installed on the outer peripheral wall of the annular seat; the fixing seat is located on one side of the sliding groove, and an insert rod is slidably connected inside the fixing seat; a second inclined surface adapted to the first inclined surface is provided at one end of the insert rod near the sliding rod; the end of the insert rod can be accommodated between two adjacent limiting protrusions; a limiting ring is fixedly connected to the outer side of the insert rod between the fixing seat and the second inclined surface. A second spring is sleeved on the outer side of the insertion rod between the limiting ring and the fixed seat. In this design, when the sliding rod moves away from the center of the annular seat, it will cause the end of the fire hose to expand outward. At the same time, multiple limiting protrusions on the side wall of the sliding rod gradually slide in the sliding groove. When the sliding rod is displaced, the first inclined surface on the side wall of the limiting protrusion and the second inclined surface on the end of the insertion rod come into contact. The movement of the sliding rod will drive the insertion rod to move away from the sliding rod through the limiting protrusion and squeeze the second spring. When the end of the insertion rod and the limiting protrusion are misaligned, the second spring rebounds and pushes the insertion rod to reset, limiting the limiting protrusion that it just passed and preventing the sliding rod from moving towards the center of the annular seat.
[0015] It needs to be explained that the first inclined surface extends from the side wall of the limiting protrusion toward the end face away from the center of the annular seat, while the second inclined surface faces toward the center of the annular seat. Therefore, when the sliding rod moves away from the center of the annular seat, the first inclined surface will contact the second inclined surface and push the insertion rod to move. Conversely, when the sliding rod wants to move toward the center of the annular seat, the limiting protrusion will be blocked by the insertion rod, thus restricting the movement of the sliding rod.
[0016] Preferably, an automatic reset component is also provided on the outer side of the annular seat corresponding to the multiple clamping components. The automatic reset component is connected to the clamping components and has: two support plates fixed to the outer peripheral wall of the annular seat with symmetrical sliding grooves; a horizontal plate is fixed between the ends of the two support plates away from the annular seat; one end of the sliding rod passes through the horizontal plate; an annular ring is fixedly installed on the horizontal plate; and a third spring is sleeved on the outer side of the sliding rod between the annular ring and the horizontal plate. In this scheme, after the support mechanism has completed its work, the operator only needs to pull the insertion rod to disengage its end from the limiting protrusion. Under the action of the third spring, the sliding rod will move towards the center of the annular seat, thereby resetting the clamping components.
[0017] It needs to be explained that when the sliding rod moves away from the center of the annular seat, the annular ring on the outer wall of the sliding rod will gradually approach the horizontal plate and squeeze the third spring. However, due to the restriction of the limiting protrusion and the insert rod, the third spring cannot release kinetic energy. When the insert rod loses its restriction on the limiting protrusion, the third spring can release kinetic energy to drive the sliding rod to reset.
[0018] Preferably, the inner tube heating assembly includes: a fixed platform, a rotating plate rotatably connected to the side wall of the fixed platform facing the annular seat, a first motor fixedly connected to the other side wall of the fixed platform, the output end of which is fixedly connected to the rotating plate, a connecting rod provided on the side wall of the rotating plate near the annular seat, an inner heating tube fixedly installed on the end of the connecting rod away from the rotating plate, the inner heating tube being located among the multiple clamping assemblies and inserted by the end of a fire hose; in this scheme, when the output end of the first motor rotates, it will electrically rotate the rotating plate, and the rotating plate controls the rotation of the connecting rod mounted on one side wall of its side wall, the connecting rod being connected to the inner heating tube (the outer diameter of the connecting rod is smaller than the outer diameter of the inner heating tube, the purpose of which is to facilitate subsequent operation of the clamping plate), the rotation of the rotating plate will transfer kinetic energy to the connecting rod, thereby controlling the rotation of the inner heating tube.
[0019] Preferably, the adjustment assembly includes: an adjustment groove formed on the rotating plate, the adjustment groove extending from the center of the rotating plate to the side, and a first screw rotatably connected within the adjustment groove; a second motor fixedly connected to the outer wall of the rotating plate, the output end of which is fixedly connected to the end of the first screw; one end of a connecting rod slidably connected within the adjustment groove, and the end of the connecting rod threadedly connected to the first screw; in this configuration, when the output end of the second motor rotates, it controls the first screw to rotate, and the first screw drives the end of the connecting rod screwed to the outside to move within the adjustment groove. One end of the adjustment groove is located at the center of the rotating plate, and the other end is located at the edge of the rotating plate. Therefore, when the connecting rod is displaced, it drives the inner heating tube to move from the center of the rotating plate to the edge, thereby increasing the diameter of the inner heating tube during rotation in conjunction with the rotation of the rotating plate.
[0020] Preferably, the transmission assembly includes: a support rod fixedly connected to the side wall of the sliding rod near the fixed platform; a top rod fixedly connected to the end of the support rod; the top rod extending towards the connecting rod; a stop plate fixedly connected to the end of the top rod near the connecting rod, abutting against the connecting rod; an extension rod fixedly connected to the side wall of the annular seat below the support rod; a limit sleeve fixedly connected to the end of the extension rod; and the limit sleeve sleeved outside the top rod. In this embodiment, a support rod is fixedly installed on the outer wall of the sliding rod, and a top rod perpendicular to it is provided. A stop plate is fixedly installed on the end of the top rod near the connecting rod, and the stop plate fits against the outside of the connecting rod. When the connecting rod is adjusted by the adjusting assembly to control its rotation range, the connecting rod will gradually contact the transmission assemblies on multiple clamping assemblies in sequence, and push the transmission assemblies one by one to move away from the center of the annular seat. The transmission assembly controls the synchronous displacement of the clamping assemblies, thereby using the clamping assemblies to flare and stretch the fire hose.
[0021] It should be explained that setting the limit sleeve can ensure the stability of the push rod during its movement, while preventing the push rod from shifting or becoming misaligned.
[0022] Preferably, the first moving component includes: a first moving groove formed on the base, a second screw rotatably connected in the first moving groove, a third motor fixedly connected to the side wall of the base, the output end of which is fixedly connected to the end of the second screw, a first moving seat slidably connected in the first moving groove and threadedly connected to the second screw, and two support seats symmetrically fixedly connected to the outer side of the annular seat, both of which are fixedly installed on the first moving seat; in this scheme, the output end of the third motor controls the rotation of the second screw, thereby causing the first moving seat to move horizontally in the first moving groove through the second screw, thereby adjusting the distance between the annular seat and the support mechanism.
[0023] It should be noted that, in the initial state, the first movable seat is located on the side of the first movable slot that is closer to the second movable slot.
[0024] Preferably, the second moving component includes: a second moving groove formed on the base, a third screw rotatably connected in the second moving groove, a fourth motor fixedly connected to the side wall of the base, the output end of which is fixedly connected to the end of the third screw, a second moving seat slidably connected in the second moving groove, the second moving seat and the third screw being threadedly connected, and the top end of the second moving seat being fixedly connected to the fixed platform; in this scheme, the output end of the fourth motor controls the rotation of the third screw, and the third screw drives the second moving seat to move horizontally in the second moving groove, thereby adjusting the distance between the support mechanism and the annular seat.
[0025] In the initial state, the support mechanism is located on the side of the second moving groove closer to the first moving groove. After the support mechanism has completed its work, it moves laterally along the second moving groove in a direction away from the first moving groove.
[0026] Compared with the prior art, the beneficial effects of the present invention are: a manufacturing process for a wear-resistant fire hose according to the present invention: 1. In this device, the inner heating pipe is inserted from the end of the fire hose. The first motor controls the rotation of the inner heating pipe, while the second motor, in conjunction with the first screw, controls the movement of the inner heating pipe. The inner heating pipe moves from the center of the rotating plate to the edge, thereby increasing the diameter range of the inner heating pipe during rotation. The connecting rod set on one side of the inner heating pipe will push multiple transmission components to gradually move away from the fire hose. At the same time, the transmission components drive the clamping components to move, stretching the end of the fire hose outward, thereby expanding the fire hose port.
[0027] 2. In this device, after the support mechanism opens the fire hose port to a certain extent, the second moving component controls the support mechanism to move away from the annular seat. The person (with the help of external tools or devices) can place the connector to be loaded inside the fire hose port. The fire hose is reset by separating the anti-displacement component and the clamping component, thereby completing the assembly of the connector. This assembly method can ensure that the fire hose is in the supported state when the connector is assembled. On the other hand, the arc heating plate is still heating the fire hose when the connector is placed, avoiding the fire hose from loosening due to loss of high temperature, which would affect the normal assembly of the connector.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0034] Please see Figure 1-6This invention provides a technical solution: a manufacturing process for wear-resistant fire hoses, comprising: a base 1, a clamping mechanism 2 movably connected to the base 1, an end of a fire hose to be processed fixedly installed inside the clamping mechanism 2, and a support mechanism 3 movably installed on one side of the base 1 of the clamping mechanism 2, the end portion of the support mechanism 3 being inserted into the end of the fire hose. The clamping mechanism 2 has: an annular seat 21, on which multiple clamping components 22 are distributed at equal angles, each clamping component 22 being slidably connected to the annular seat 21, and the end of the clamping component 22 near the center of the annular seat 21 being used to clamp the fire hose. An anti-displacement component 23 is also provided on the outer peripheral wall of the annular seat 21 on one side. The anti-displacement component 23 and the clamping component 22 are detachably connected. The support mechanism 3 has an inner tube heating component 31, which is rotatably connected to one side of the annular seat 21. An adjustment component 32 is also provided on the inner tube heating component 31. The adjustment component 32 is used to adjust the centripetal distance of the inner tube heating component 31. A transmission component 24 is also provided on each clamping component 22. The transmission component 24 is placed on the inner tube heating component 31. A first moving component 11 and a second moving component 12 are respectively provided on the base 1 to control the relative movement of the clamping mechanism 2 and the support mechanism 3.
[0035] Specifically, this device also includes: a cooling mechanism set on the base 1. The cooling mechanism includes two columns symmetrically set on the base 1. The columns are located on both sides of the inner heating pipe 315, and a lifting groove is vertically opened on the side wall of the column facing the inner heating pipe 315. A lifting seat is slidably connected in the lifting groove. At the same time, an electric push rod is fixedly installed at the top of the column. The output end of the electric push rod extends into the lifting groove and is fixedly connected to the lifting seat. The extension and retraction of the output end of the electric push rod drives the lifting seat to move up and down in the lifting groove. Meanwhile, a nozzle is also installed on the lifting platform. The nozzle is connected to an external coolant delivery device through a delivery pipe. The outlet of the coolant delivery device is equipped with a pump body. The pump body pumps the coolant into the delivery pipe and then delivers it to the nozzle position through the delivery pipe. The nozzle sprays the coolant to the fire hose port position, thereby ensuring rapid cooling of the fire hose after the joint assembly is completed.
[0036] In addition, a water receiving tank is provided on the base 1 between the first moving groove 111 and the second moving groove 121. After the coolant is sprayed onto the surface of the fire hose, it will drip down. The water receiving tank is used to collect the dripping coolant.
[0037] Furthermore, the clamping assembly 22 includes: a sliding groove 221 formed on the annular seat 21; a sliding rod 222 slidably connected within the sliding groove 221; an arc-shaped heating plate 223 fixedly installed at the bottom end of the sliding rod 222; the arc-shaped heating plate 223 conforming to the outer surface of the fire hose; a clamping groove 224 formed on the side wall of the sliding rod 222 above the arc-shaped heating plate 223; a sliding rod 225 fixedly installed within the clamping groove 224; and a clamping groove 224 fitted onto the sliding rod 225. 4. A sliding connection plate 226 is L-shaped and has a horizontal section that is slidably connected to the clamping groove 224 and a vertical section fixed to the end of the horizontal section. The vertical section extends to the side of the arc-shaped heating plate 223 away from the sliding rod 222, and a clamping plate 227 is fixedly installed on the end of the vertical section. The clamping plate 227 and the horizontal section are parallel to each other. A first spring 228 is also sleeved on the sliding rod 225 on the side of the horizontal section near the arc-shaped heating plate 223.
[0038] Specifically, such as Figure 2 As shown in the enlarged view, the inner arc surface of the arc-shaped heating plate 223 near the support mechanism 3 is provided with an arc-shaped groove. When the fire hose is assembled, its end is located in the arc-shaped groove. At the same time, the depth of the arc-shaped groove matches the height of the clamping plate 227. When the clamping plate 227 presses the end of the fire hose into the arc-shaped groove, the side wall of the clamping plate 227 away from the fire hose is flush with the inner surface of the arc-shaped heating plate 223, which effectively ensures the stable insertion of the inner heating pipe 315 and avoids the problem that the inner heating pipe 315 cannot be inserted due to the restriction of the position of the clamping plate 227.
[0039] This method also ensures that the internal heating pipe 315 is stably attached to the inner surface of the fire hose, and the heat generated by the internal heating pipe 315 after being connected to an external power source can be stably transferred to the fire hose.
[0040] It should be explained that the clamping plate 227 can be made of a thermally conductive material, thereby ensuring that the heat from the internal heating pipe 315 can be transferred to the fire hose that is blocked by the clamping plate 227.
[0041] Furthermore, the anti-displacement component 23 includes: a plurality of limiting protrusions 231 fixedly installed at equal intervals along the height of the side wall of the sliding rod 222; each limiting protrusion 231 has a first inclined surface 232 extending toward its top wall on the side wall away from the sliding rod 222; a fixing seat 233 is also fixedly installed on the outer peripheral wall of the annular seat 21; the fixing seat 233 is located on one side of the sliding groove 221; and a plug rod 234 is slidably connected inside the fixing seat 233; a second inclined surface 235 adapted to the first inclined surface 232 is provided at one end of the plug rod 234 near the sliding rod 222; the end of the plug rod 234 can be accommodated between two adjacent limiting protrusions 231; a limiting ring 236 is fixedly connected to the outside of the plug rod 234 between the fixing seat 233 and the second inclined surface 235; and a second spring 237 is sleeved on the outside of the plug rod 234 between the limiting ring 236 and the fixing seat 233.
[0042] Specifically, two sets of anti-displacement components 23 can be provided, which are symmetrically arranged on both sides of the sliding groove 221. The two sets of anti-displacement components 23 can stably ensure that the sliding rod 222 will not be displaced after being limited, thereby avoiding affecting the tensioning effect of the fire hose port.
[0043] Furthermore, an automatic reset assembly 25 is also provided on the outer side of the annular seat 21 corresponding to multiple clamping assemblies 22. The automatic reset assembly 25 is connected to the clamping assembly 22 and has: two support plates 251 fixedly connected to the outer peripheral wall of the annular seat 21 by a symmetrical sliding groove 221; a horizontal plate 252 is fixedly connected between the ends of the two support plates 251 away from the annular seat 21; one end of the sliding rod 222 passes through the horizontal plate 252; an annular ring 253 is also fixedly installed on the horizontal plate 252; and a third spring 254 is sleeved on the outer side of the sliding rod 222 between the annular ring 253 and the horizontal plate 252.
[0044] Specifically, the support rod 241 is installed below the annular ring 253. When the sliding rod 222 moves, it drives the annular ring 253 to move upward and simultaneously compresses the third spring 254. When the sliding rod 222 moves, it can also drive the support rod 241 to move upward synchronously.
[0045] Furthermore, the inner tube heating assembly 31 includes: a fixed platform 311, a rotating plate 312 rotatably connected to the side wall of the fixed platform 311 facing the annular seat 21, a first motor 313 fixedly connected to the other side wall of the fixed platform 311, the output end of which is fixedly connected to the rotating plate 312, a connecting rod 314 provided on the side wall of the rotating plate 312 near the annular seat 21, an inner heating tube 315 fixedly installed on the end of the connecting rod 314 away from the rotating plate 312, the inner heating tube 315 being located between multiple clamping assemblies 22 and inserted by the end of a fire hose.
[0046] Specifically, the internal heating pipe 315 is electrically connected to an external power source. At the same time, the diameter of the internal heating pipe 315 is slightly smaller than the inner diameter of the fire hose to ensure that the internal heating pipe 315 can be stably inserted into the fire hose during assembly.
[0047] Furthermore, the adjustment assembly 32 includes: an adjustment groove 321 formed on the rotating plate 312, the adjustment groove 321 extending from the center of the rotating plate 312 to the side, and a first screw 322 rotatably connected inside the adjustment groove 321; a second motor 323 fixedly connected to the outer wall of the rotating plate 312, the output end of which is fixedly connected to the end of the first screw 322; and one end of a connecting rod 314 slidably connected inside the adjustment groove 321, and the end of the connecting rod 314 threadedly connected to the first screw 322.
[0048] Furthermore, the transmission assembly 24 includes: a support rod 241 fixedly connected to the side wall of the sliding rod 222 near the fixed platform 311; a top rod 242 fixedly connected to the end of the support rod 241; the top rod 242 extending towards the connecting rod 314; a stop plate 243 abutting against the connecting rod 314 fixedly connected to the end of the top rod 242 near the connecting rod 314; an extension rod 244 fixedly connected to the side wall of the annular seat 21 below the support rod 241; a limit sleeve 245 fixedly connected to the end of the extension rod 244; and the limit sleeve 245 sleeved outside the top rod 242.
[0049] Specifically, a rotating ring is provided on the outer periphery of the connecting rod 314. The rotating ring is rotatably sleeved on the outside of the connecting rod 314. By providing the rotating ring, the friction when the connecting rod 314 and the abutment 243 come into contact can be reduced, thereby reducing the wear on the abutment 243.
[0050] Furthermore, the first moving component 11 includes: a first moving groove 111 formed on the base 1, a second screw 112 rotatably connected in the first moving groove 111, a third motor 113 fixedly connected to the side wall of the base 1, the output end of which is fixedly connected to the end of the second screw 112, a first moving seat 114 slidably connected in the first moving groove 111 and threadedly connected to the second screw 112, and two support seats 115 symmetrically fixedly connected to the outer side of the annular seat 21, both support seats 115 being fixedly installed on the first moving seat 114.
[0051] Specifically, the purpose of setting the first moving component 11 is as follows: when the device is in its initial state, the first moving component 11 controls the annular seat 21 to move to the side of the first moving groove 111 close to the second moving groove 121. When the support mechanism 3 completes its work and moves away from the annular seat 21, the assembly of the connector can be realized. When the port of the fire hose is completely wrapped around the outside of the connector end, the first moving component 11 can control the annular seat 21 to move along the first moving groove 111 away from the second moving groove 121, thereby facilitating the removal of the clamping plate 227 from the fire hose port.
[0052] Furthermore, the second moving component 12 includes: a second moving groove 121 formed on the base 1, a third screw 122 rotatably connected in the second moving groove 121, a fourth motor 123 fixedly connected to the side wall of the base 1, the output end of which is fixedly connected to the end of the third screw 122, a second moving seat 124 slidably connected in the second moving groove 121, the second moving seat 124 and the third screw 122 being threadedly connected, and the top end of the second moving seat 124 being fixedly connected to the fixed platform 311.
[0053] Specifically, the purpose of setting the second moving component 12 is that after the support mechanism 3 has completed its work, the second moving component 12 can be used to control the support mechanism 3 to move away from the annular seat 21, so that the internal heating pipe 315 can be moved out from the fire hose port, which will facilitate the subsequent assembly of the connector.
[0054] Working principle and usage process of this invention: After the invention is installed, The fire hose port is placed between multiple clamping components 22 and the outer peripheral wall of the fire hose port is attached to the arc heating plate 223. The fire hose port is fixed by the cooperation of the clamping plate 227 and the arc heating plate 223. Subsequently, the output of the fourth motor 123 controls the third screw 122 to rotate and drives the second moving seat 124 to move closer to the ring seat 21, so that the inner heating pipe 315 is inserted from the fire hose port, and the inner heating pipe 315 and multiple arc-shaped heating plates 223 heat the fire hose. The output of the first motor 313 controls the rotation of the rotating plate 312. The rotating plate 312 drives the internal heating tube 315 to rotate through the connecting rod 314. At the same time, the second motor 323 controls the rotation of the first screw 322. The first screw 322 drives the connecting rod 314 to move gradually from the center of the rotating plate 312 to the edge (the first screw 322 has a relatively dense number of threads, so it can slowly drive the connecting rod 314 to move). The connecting rod 314, together with multiple abutments 243, controls the sliding rod 222 to move gradually away from the center of the annular seat 21. When the sliding rod 222 is displaced, it pulls the fire hose port through the clamping assembly 22 to expand it, so that the diameter of the fire hose port is larger than the diameter of the connector end, which facilitates assembly. After the expansion is completed, the second moving component 12 controls the support mechanism 3 to move out from the fire hose port and place the connector inside the fire hose port. At the same time, the anti-retraction component 23 is pulled to cooperate with the automatic reset component 25 to drive multiple sliding rods 222 closer to the center of the annular seat 21, so that the fire hose port is wrapped around the outside of the connector end. Then, the first moving component 11 controls the annular seat 21 to move away from the second moving groove 121, and the clamping plate 227 is withdrawn from the arc-shaped heating plate 223, completing the assembly of the connector.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
