Description
Technical field
The invention belongs to technical field of road maintenance facilities, be specifically related to a kind of heating arrangements of asphalt pavement heater.
Background technology
Flexible pavement after use after a while, the time regular meeting hole, hole and decentralized crackle and so on appear and cause the damage phenomenon, must in time carry out the maintenance reparation, otherwise hole, hole and crackle can enlarge gradually, cause difficulty to reparation.Often adopt oil to guarantee the repair free of charge the benefit mode to the repairing of hole, hole and decentralized crackle and so in the prior art, this repairing method has the strong point of work efficiency height, economical with materials, but because the oil bag that injects is difficult to and protobitumen between produce good affinity, therefore shelling appears, cause repairing again the rate height.And have good between the pitch that will make new interpolation and the original roadbed pitch or claim the friendly effect that combines, then need to dig open circuit surface, this method has the low advantage of the rate of repairing again, but the workload of long construction period, input reparation is big, but also causes the serious waste of material.Particularly the snow moon in severe winter, because of road surface is covered by ice and snow, the previous work of snow removing water ice brings extra labour intensity burden for maintenance team.Elimination means for the face central authorities seam of newly building the road also are very difficult in addition.
Can be seen in the many moneys technical scheme that is suitable for flexible pavement reparation maintenance in Chinese patent literature, patent No. ZL03264008.0 discloses the efficient microwave road heater; ZL03264009.9 has disclosed the microwave asphalt road heater; ZL200320117944.4 has disclosed a kind of microwave asphalt road heater; The public all safe and reliable microwave road heaters of ZL200420046641.2; ZL200420047053.0 has introduced the microwave road heater; ZL200420071607.0 has recommended microwave road heater and ZL200520055873.9 to recommend a kind of water-cooling type microwave road heater.The above-mentioned patented technology scheme of enumerating all is to use microwave that flexible pavement is heated, though can realize the maintenance reparation to flexible pavement, microwave heating equipment complex structure, and instructions for use harshness can not obtain the approval of maintenance department.
China utility model patent notice of authorization CN2856135Y provides a kind of asphalt pavement heater (by the applicant's application), this technical scheme is after applicant's industrialization, confirmed the strong point that has easy construction and can save patching material and saving of work and time, the structure of the employed heating arrangements of this patented technology scheme (patent claims the infrared rays heating unit) is by (the applicant has carried out the adjustment of non-distorting property to Reference numeral) shown in Figure 3, comprise cap 1, be fixed in the gauze wire cloth 2 on the shirt rim of cap 1 and be located at burner 3 (patent claims fuel cap) in the lid chamber of cap 1, and burner 3 occupy the central authorities in the lid chamber of cap 1, when liquefied gas is introduced burner 3, after igniting, by the burning of burner 3 with heat radiation to gauze wire cloth 2, until giving hole, hole or dispersed cracks with heat radiation corresponding to the flexible pavement of gauze wire cloth below by gauze wire cloth 2, make flexible pavement softening, implement then to repair (the 5th page of 3-11 of manual that asks for an interview this patent is capable).Not ccontaining doubt, heating arrangements is the key mechanism of asphalt pavement heater, its structure rationally whether not only can directly influence speed of application, but also can influence the reasonable consumption of the energy (liquefied gas).In view of this, the heating arrangements that relates among the CN2856135Y exists and not only is unfavorable for energy conservation but also is not enough to improve to the thermal effect that adds corresponding to the integral body heating of the flexible pavement of gauze wire cloth 2 belows, because burner 3 is located at the shell chamber central authorities of cap 1, when burner 3 work (during burning), just rise corresponding to the flexible pavement temperature in the zone of burner 3 belows is very fast, reach the pavement temperature of being repaired about 160 ℃, but the pavement temperature away from burner 3 places often needs long time just can reach suitable temperature of repairing, thereby the amount that consumes liquefied gas increases, prolong the heat time heating time of road pavement, and construction speed is affected.If the volume of burner 3 is increased, so that its area corresponding to road is increased, but so select the waste of meeting and then aggravation combustion gas, and still do not have and help in improving speed of application; Again, if increase the quantity of burner 3, for example four bights and the central authorities at cap 1 respectively establish burner 3, so not only cause complex structure, and waste energy more.Therefore how not only to save combustion gas but also obtain between the whole heating of road pavement and find the problem of rational equalization point to suffer from the industry that comprises the applicant for a long time, the exploration that reached 3 years through the applicant, finally find a way to resolve the problem, technical scheme described below produces under this background.
