DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] Embodiment 1: Reference Figure 1-11A device for rapidly heating asphalt coiled material comprises a shell 1 and a placing cylinder 2 fixed inside the shell 1 for placing a coiled material 16, moving wheels are arranged on both sides of the shell 1, a handle is fixed on the back of the shell 1, a heating chamber 101 and a preheating chamber 102 are arranged inside the shell 1, the preheating chamber 102 is arranged above the heating chamber 101 and are interconnected, the preheating chamber 102 is cylindrical, the heating chamber 101 is triangular, the preheating chamber 102 is arranged tangent to the vertical surface of the heating chamber 101, the placing cylinder 2 is suspended in the preheating chamber 102 and is fixed inside the preheating chamber 102 by a plurality of supporting columns, a plurality of air holes are opened on the surface of the placing cylinder 2, an outlet 201 for pulling out the coiled material 16 is opened on the surface of the placing cylinder 2, and the outlet 201 The position corresponds to the connection between the heating chamber 101 and the preheating chamber 102. An intake port is provided on the same side of the shell 1 as the placing cylinder 2. A baffle 202 for limiting the coil 16 is fixed at the bottom of the intake port of the placing cylinder 2. A conveying roller 3 is rotated at the connection between the preheating chamber 102 and the heating chamber 101. The conveying roller 3 is away from the vertical plane of the heating chamber 101. The conveying roller 3 is driven to rotate by a driving motor, and the driving motor is fixed to the side of the shell 1. A guide plate 4 is fixed inside the heating chamber 101, and the guide plate 4 is arranged below the conveying roller 3. The front position of the bottom of the heating chamber 101 is an open structure. A cover plate 14 is hinged on the surface of the shell 1. The cover plate 14 corresponds to the position of the intake port of the shell 1. A flattening wheel 15 is fixed at the front end of the shell 1.

[0035] It can be understood that the coil 16 is placed in the placement cylinder 2 through the insertion inlet, with the asphalt side of the coil 16 facing outward, and one end of the coil 16 is inserted between the conveying roller 3 and the shell 1 through the outlet 201, and the conveying roller 3 is driven to rotate by the driving motor, so that one end of the coil 16 moves downward, and one end of the coil 16 is sent to the front end of the shell 1 through the guide plate 4. When the coil 16 touches the ground, the conveying roller 3 continues to release the coil 16, and by pulling the shell 1 to move backward, the coil 16 is laid on the ground with the asphalt side facing downward.

[0036] Specifically, a heating assembly 5 is provided on the rear side of the shell 1, and the heating assembly 5 includes a gas tank 501 installed on the back side of the shell 1. Two fixing rings are fixed on the back side of the shell 1. The gas tank 501 is installed on the back side of the shell 1 through the two fixing rings. A solenoid valve is provided on the surface of the exhaust port of the gas tank 501. The upper end of the exhaust port of the gas tank 501 is connected to a flamethrower 502 through a hose. The flamethrower 502 is fixed inside the heating chamber 101. The flamethrower 502 faces the intersection of the coil 16 and the ground. The lower end of the guide plate 4 is arranged in front of the flamethrower 502, and the lower end of the guide plate 4 is higher than the height of the flamethrower 502.

[0037] It can be understood that the gas tank 501 is opened through the solenoid valve, so that the gas in the gas tank 501 is ejected through the hose and the flamethrower 502, and the igniter ignites the gas, so that the flame ejected from the flamethrower 502 heats the asphalt on the surface of the coil 16 until it melts. During the movement of the shell 1, the flattening wheel 15 presses the coil 16 to the ground, and the residual heat of the flame rises to the preheating chamber 102 through the air, and the residual heat is used to preheat the coil 16 through the air holes on the surface of the placement tube 2. Therefore, when the flamethrower 502 heats the coil 16, the asphalt melts faster, shortens the heating time, and at the same time increases the moving speed of the shell 1, thereby increasing the efficiency of laying the asphalt coil 16.

[0038] Specifically, a plurality of fans 6 for blowing air upward are fixed at the connection between the heating chamber 101 and the preheating chamber 102. The plurality of fans 6 are arranged at intervals. A plurality of air inlets 7 are provided on the back of the shell 1. The plurality of air inlets 7 are vertically arranged long holes. The plurality of air inlets 7 are arranged below the fans 6. An air outlet 8 is provided in front of the preheating chamber 102. The air outlet 8 is a horizontally arranged long hole and extends outward. The height of the air outlet 8 is located below the placement tube 2.

[0039] It can be understood that, by operating the fan 6, the residual temperature in the heating chamber 101 is accelerated to be transported to the preheating chamber 102, so that the air in the preheating chamber 102 can flow through the outer surface of the placement tube 2, and under the action of the air inlet 7, the ambient temperature air enters the shell 1 to neutralize the residual temperature generated by the flamethrower 502, and is discharged through the air outlet 8, so that the residual temperature entering the preheating chamber 102 is reduced, avoiding excessive preheating of the coil 16 due to excessive temperature, causing the asphalt on the surface of the coil 16 to melt prematurely and make the coil 16 sticky, affecting the normal use of the coil 16.

[0040] Specifically, a temperature-sensing telescopic component 9 is fixed on the top of the shell 1, and a first adjusting component 10 and a second adjusting component 11 are respectively arranged on both sides of the temperature-sensing telescopic component 9. The first adjusting component 10 is used to adjust the size of the air outlet 8, and the second adjusting component 11 is used to adjust the size of the multiple air inlets 7. The temperature-sensing telescopic component 9 includes a U-shaped tube body 901, which is transversely arranged on the top of the shell 1, the lower end of the tube body 901 is arranged inside the shell 1, and the upper end of the tube body 901 is arranged outside the shell 1. A first piston rod 902 slides on the outer end of the tube body 901, a guide rail 903 is fixed on the top of the shell 1, and the outer end of the first piston rod 902 slides on the surface of the guide rail 903. The inside of the tube body 901 is filled with a thermal expansion flow medium, and the thermal expansion flow medium is mercury or kerosene; The first adjustment component 10 includes an air guide plate 1001 rotating inside the air outlet 8, the rotation axis of the air guide plate 1001 is arranged horizontally and close to the lower end of the air guide plate 1001, a first pull rope 1002 is fixed to the upper end of the air guide plate 1001, a plurality of first guide rings 1003 and a second guide ring 1004 are fixed to the surface of the shell 1, the other end of the first pull rope 1002 passes through the plurality of first guide rings 1003 and the second guide ring 1004 and is fixed to one side of the outer end of the first piston rod 902, the first guide rings 1003 are all arranged in the middle of the shell 1, the second guide ring 1004 is located close to the guide rail 903 and away from the end of the tube body 901, a tension spring 1005 is fixed to the lower end of the air guide plate 1001, the other end of the tension spring 1005 is fixed to the upper end of the air outlet 8, and a plurality of ventilation grooves are arranged at intervals at the lower end of the air guide plate 1001; The second adjustment component 11 includes a windshield 1101 for shielding the air inlet 7. Two slide rails 1102 are fixed on the back of the shell 1. The windshield 1101 slides vertically on the back of the shell 1 through the two slide rails 1102. There are two groups of windshields 1101, which are symmetrically arranged on both sides of the gas storage tank 501 to shield multiple air inlets 7 respectively. The two windshields 1101 are fixedly connected by a U-shaped connecting rod 1103. A winding wheel 1104 is rotatable on the top of the shell 1 and is fixedly connected to a third guide ring 1108. The winding wheel 1104 is The surface is wound with a second pull rope 1105, the other end of which passes through a third guide ring 1108 and is fixed on the upper surface of the connecting rod 1103. A gear 1107 is fixedly mounted on the lower end of the winding wheel 1104. A rack 1106 is fixed on the outer end of the first piston rod 902 close to the winding wheel 1104. The rack 1106 is meshed with the gear 1107. When the windshield 1101 is at the lowest point, the bottom end of the windshield 1101 is higher than the lower ends of the multiple air inlets 7. The first pull rope 1002 and the second pull rope 1105 are both made of steel wire ropes. It can be understood that, in the initial state, the first piston rod 902 is located inside the tube body 901, and the first pull rope 1002 is in a tightened state. The first pull rope 1002 is tightened to drive the air guide plate 1001 to block the air outlet 8, and basic exhaust is performed through multiple ventilation grooves, while the wind shield plate 1101 is located at the lowest point, and the multiple air inlets 7 are not completely blocked, and basic air intake can be performed. By arranging a heat-expanding flow medium in the tube body 901, when the temperature in the preheating chamber 102 rises, the heat-expanding flow medium expands due to the heat, pushing the first piston rod 902 to slide toward the outer end, which will drive the first pull rope 1 The upper end of the first pull rope 1002 is close to the second guide ring 1004, so that the first pull rope 1002 is relaxed, and under the action of the tension spring 1005, the air guide plate 1001 is driven to rotate, increasing the air outlet width of the air outlet 8, and at the same time, the upper end of the air guide plate 1001 is rotated into the preheating chamber 102, and the circulating air is intercepted and circulated to the outside, thereby improving the efficiency of hot air outflow. At the same time, the first piston rod 902 drives the rack 1106 to move, and under the cooperation of the gear 1107 and the rack 1106, the gear 1107 and the winding wheel 1104 are driven to rotate, thereby contracting the second pull rope 1105. The second pull rope 1105 drives the connecting rod 1103 and the two wind shields 1101 to slide upward on the surface of the slide rail 1102, thereby expanding the air inlet channel of the air inlet 7, allowing more room temperature air to enter, and further reducing the residual temperature rising into the preheating chamber 102, so as to achieve the effect of real-time regulation of the size of the air inlet 7 and the air outlet 8 as the temperature in the preheating chamber 102 rises, and keep the temperature in the preheating chamber 102 within the range before the asphalt melts, avoiding excessive preheating of the asphalt due to excessive temperature. Since the multiple air inlets 7 are vertically arranged long holes, the wind shield 1101 needs to be raised within the required distance The distance required to rotate is greater than the distance required to pull the wind guide plate 1001. Therefore, a gear 1107 and a winding wheel 1104 are provided. The rack 1106 moves to drive the gear 1107 to rotate, so that the winding wheel 1104 rotates to wind the second pull rope 1105, thereby increasing the transmission ratio. The winding wheel 1104 can drive the second pull rope 1105 to tighten a greater length than the first pull rope 1002. By providing a plurality of ventilation grooves at the lower end of the wind guide plate 1001, and when the wind shield plate 1101 is at the lowest point, the air inlet 7 is not completely closed, so that the air inlet 7 and the air outlet 8 remain open, thereby achieving the ventilation effect.

[0041] Specifically, a lifting assembly 12 is provided on the top of the shell 1, and the lifting assembly 12 includes a lifting rod 1201 that slides vertically on the top of the shell 1 and a second piston rod 1204 that slides horizontally on the inner end of the tube body 901. The outer end of the second piston rod 1204 is hinged with a pull rod 1203, and the other end of the pull rod 1203 is hinged to one side of the lower end of the lifting rod 1201. A roller 1202 is fixed to the lower end of the lifting rod 1201. A spring 1205 is provided at the lower end of the lifting rod 1201 located inside the shell 1, which is used to drive the lifting rod 1201 to slide downward into the inside of the placing tube 2. A through groove for the pull rod 1203 to move is provided at the top of the placing tube 2.

[0042] It can be understood that as the coil 16 is used inside the placement tube 2, the diameter of the coil 16 gradually decreases, and the height inside the placement tube 2 decreases accordingly. The temperature-sensitive telescopic component 9 is arranged at the top of the shell 1. The temperature at the top of the shell 1 is usually the highest, and the temperature decreases as it goes down. The temperature-sensitive telescopic component 9 is heated to increase the ventilation speed, resulting in the temperature at the bottom of the placement tube 2 being insufficient for preheating the coil 16. By arranging the lifting rod 1201 and the pull rod 1203, the spring 1205 drives the lower end of the lifting rod 1201 to always press against the lower end of the lifting rod 1201. It touches the top of the coil 16 and slides downward as the diameter of the coil 16 decreases, thereby driving the end of the pull rod 1203 located on the surface of the lifting rod 1201 to descend, pulling the second piston rod 1204 to slide outward in the tube body 901, thereby increasing the space in the tube body 901 for storing the heat-expanding flow medium, allowing the heat-expanding flow medium to expand to the temperature required to push the first piston rod 902 to slide, so that more heat can be stored in the preheating chamber 102, and the temperature in the bottom of the placement tube 2 is sufficient to preheat the coil 16.

[0043] Specifically, a lifting plate 13 is hinged on the top of the inner wall of the placing cylinder 2 for driving the lifting rod 1201 to slide upward, and the hinged end of the lifting plate 13 is close to the side of the placing entrance of the placing cylinder 2. The inner end of the lifting plate 13 is bent upward, and a groove for the movement of the roller 1202 is provided on the upper surface of the lifting plate 13. When the lifting rod 1201 slides down to the bottom, the roller 1202 is located at the bending part of the inner end of the lifting plate 13.

[0044] It can be understood that when the coil 16 is pushed into the placement cylinder 2 through the insertion port, the coil 16 pushes the inner end of the lifting plate 13 to rotate upward, and at the same time, the roller 1202 moves on the surface of the lifting plate 13, thereby pushing the lifting rod 1201 upward through the lifting plate 13, thereby facilitating the placement of the coil 16.

[0045] Specifically, a scale line 17 is provided on the side of the lifting rod 1201 close to the gas storage tank 501 .

[0046] It can be understood that since the lifting rod 1201 will slide downward as the coil 16 decreases, the remaining amount of the coil 16 inside the placement tube 2 can be judged by observing the length of the lifting rod 1201 located outside the shell 1. Under the action of the scale line 17, the descending height of the lifting rod 1201 can be observed more accurately, thereby accurately judging the remaining amount of the coil 16.

[0047] Embodiment 2: Reference Fig.12 , which is different from the above-mentioned embodiment, the temperature-sensing telescopic component 9 includes a U-shaped tube body 901, the tube body 901 is stepped, the diameters of the two ends of the tube body 901 are smaller than the diameter of the middle part of the tube body 901, the larger diameter part of the tube body 901 is used to store the thermal expansion flow medium, the tube body 901 is transversely arranged on the top of the shell 1, the lower end of the tube body 901 is arranged inside the shell 1, the upper end of the tube body 901 is arranged outside the shell 1, and the first piston rod 902 is slidably arranged at the small diameter part of the outer end of the tube body 901; The second piston rod 1204 slides in the small diameter portion of the inner end of the tube body 901 .

[0048] It can be understood that by setting a larger diameter portion in the middle of the tube body 901 and filling the interior with a heat-expanding flow medium, the heat-expanding flow medium, after expanding due to heat, enters the smaller diameter portion, which can provide greater pressure for the first piston rod 902. At the same time, after the heat-expanding flow medium enters the small diameter tube body 901, the change in diameter can increase the flow distance of the heat-expanding flow medium, increase the moving stroke of the first piston rod 902, and achieve the distance that the first piston rod 902 needs to slide.

[0049] In the present invention, the coil 16 is placed into the placing cylinder 2 through the introduction port, one end of the coil 16 is pulled out through the outlet 201 and inserted between the conveying roller 3 and the shell 1, and the conveying roller 3 is driven by the driving motor to rotate, so that one end of the coil 16 moves downward, and one end of the coil 16 is sent to the front end of the shell 1 through the guide plate 4. When the coil 16 touches the ground, the gas storage tank 501 is opened through the solenoid valve, and the gas in the gas storage tank 501 is sprayed out through the hose and the flame-spraying pipe 502, and the igniter ignites the gas, so that the flame sprayed from the flame-spraying pipe 502 heats the asphalt on the surface of the coil 16 until it melts, and then the conveying roller 3 continues to release the coil 16, and the shell 1 is pulled to move backward, so that the coil 16 is laid on the ground, and the shell 1 moves backward. During the process, the coil 16 is pressed against the ground by the flattening wheel 15, and the coil 16 is laid, and the residual heat of the flame rises to the preheating chamber 102 through the air, and the residual heat is used to preheat the coil 16 through the air holes on the surface of the placement tube 2, so that when the flame tube 502 heats the coil 16, the asphalt melts faster, shortens the heating time, and improves the moving speed of the shell 1, thereby increasing the efficiency of laying the asphalt coil 16. At the same time, the fan 6 accelerates the transmission of the residual temperature in the heating chamber 101 to the preheating chamber 102, so that the air in the preheating chamber 102 circulates through the outer surface of the placement tube 2, and the ambient temperature air enters the shell 1 through the air inlet 7 to neutralize the residual temperature generated by the flame tube 502, and is discharged through the air outlet 8, so that the air entering the preheating chamber 102 is heated. The residual temperature in the cavity 102 is reduced to avoid excessive preheating of the coil 16 due to excessive temperature, which may cause the asphalt on the surface of the coil 16 to melt prematurely and make the coil 16 sticky, affecting the normal use of the coil 16. By setting the temperature-sensing telescopic component 9, when the temperature in the preheating cavity 102 rises, the thermal expansion flow medium expands due to the heat, pushing the first piston rod 902 to slide toward the outer end, so that the first pull rope 1002 is relaxed, and under the action of the tension spring 1005, the air guide plate 1001 is driven to rotate, increasing the air outlet width of the air outlet 8 and improving the exhaust speed. At the same time, the winding wheel 1104 reels the second pull rope 1105, so that the second pull rope 1105 drives the connecting rod 1103 and the two wind shields 1101 to slide upward on the surface of the slide rail 1102, expanding the air intake The air inlet passage of port 7 allows more room temperature air to enter, further reducing the residual temperature that rises into the preheating chamber 102. When the temperature inside the preheating chamber 102 decreases, the thermally expanded flow medium contracts, driving the first piston rod 902 to retract, and the air guide plate 1001 is pulled to rotate by the first pull rope 1002 to reduce the size of the air outlet 8. The winding wheel 1104 releases the second pull rope 1105, causing the windshield plate 1101 to drop according to its own gravity, reducing the size of the air inlet, thereby reducing the entry of room temperature air and maintaining the temperature in the preheating chamber 102. As the coil 16 is used, the diameter of the coil 16 gradually decreases, causing the spring 1205 to drive the lower end of the lifting rod 1201 to always contact the top of the coil 16, and slide downward as the diameter of the coil 16 decreases.The pull rod 1203 pulls the second piston rod 1204 to slide outward in the tube body 901, thereby increasing the space of the tube body 901 for storing the heat-expanding fluid medium, so that the heat-expanding fluid medium expands to the temperature required to push the first piston rod 902 to slide, so that more heat can be stored in the preheating chamber 102, so that the temperature at the bottom of the placement cylinder 2 is sufficient to preheat the coil 16, achieving the purpose of precise temperature control, and by observing the height of the lifting rod 1201, the remaining amount of the coil 16 can be judged and the coil 16 can be added in time.
