Detailed description of the invention
During traditional bituminous paving rake pine, need road pavement to preheat, then carry out rake pine, need two
Process.But, during the preheating of road surface, it is beneficial to rake pine for fully making bituminous paving obtain softening, frequently with to same
One place carries out long-time heating or the method improving heating-up temperature: the common defects of both approaches is, consumption
Taking the more energy, effect is unsatisfactory simultaneously, reason be long-time or under the effect of high temperature, asphalt road
Easily there is coking phenomenon in face, has influence on rake pine process on the contrary；It addition, carry out rake pine after preheated, need more
Coordinate closely, but can not accomplish effectively to coordinate in actual mechanical process so that road surface is multiple after softening to be become again
Firmly, many troubles are brought to actual mechanical process.
For these problems, the present invention proposes a kind of spike up apparatus, uses integral structure, preheats and harrow pine
Process slitless connection, makes road surface fully soften and is beneficial to harrow pine process, effectively protect pavement structure simultaneously, make
Road surface operation can be carried out without any confusion.
As it is shown in figure 1, a kind of spike up apparatus that can simultaneously heat old asphalt concrete, including chassis, the end
Road surface pre-heating system, Hot-blast Heating induction system are installed on the vehicle frame 25 of jiggering and harrow pine heating system:
Rake pine heating system includes being arranged on bottom vehicle frame 25 and heating rake teeth 19 adjustable with ground distance, heating rake
Tooth 19 inner hollow, heating rake teeth 19 can move along the direction being parallel to ground；Hot-blast Heating induction system bag
Including air stove 6, the pressurization hot blast that air stove 6 provides flows to heat rake teeth 19 and from heating rake teeth 19 inside
Act on ground；Road surface pre-heating system includes the heating pad wall 22 being arranged on bottom vehicle frame 25, heating pad wall 22
Between heating rake teeth 19 and driver's cabin 1, the distance scalable between itself and ground.
The operation principle of the present invention is, bituminous paving is carried out by the infrared ray produced by bituminous paving pre-heating system
Rapidly pre-warming, then stretches into the deep layer of the bituminous paving being preheated softening by heating rake teeth 19, and Hot-blast Heating is defeated
The hot blast sending system feed is discharged by the end of heating rake teeth 19 and bituminous paving deep layer is carried out post bake,
By moving left and right of heating rake teeth 19, the bituminous paving softened is carried out rake pine simultaneously.
Road surface pre-heating system and rake pine heating system are integrated on the vehicle frame 25 of chassis, one in front and one in back arrange,
Along with travelling forward of chassis, as long as adjusting preheating rate and speed, in the situation that chassis speed stabilizing travels
Under, preheating and rake pine process can be made to closely cooperate, along with the traveling of vehicle, the rake pine on road surface can be completed, relatively
Traditional mode is compared, and only can complete overall work by an equipment.
For road pavement carry out preheating for heating pad wall 22, heating pad wall 22 acts on by the way of infra-red radiation
Road surface, infrared ray can reach the penetration capacity of 2～3 inches to bituminous concrete, wanting when meeting actually used
Ask；And the distance between heating pad wall 22 and road surface can adjust, road conditions structure preferably in the case of, can be by
Heating pad wall 22 adjust to road surface degree relatively, make infrared energy useful effect in ground, improve
The pre-thermal efficiency；The position of heating pad wall 22 is relatively heated rake teeth 19 and is being transported forward closer to driver's cabin 1, such vehicle
Cooperation is easily facilitated time dynamic.
In rake pine heating system, act on road surface for heating rake teeth 19, this is a kind of to arrange in rake teeth
The structure of empty passage, the high-temperature hot-air of pressurization, when turning over rake road surface, is acted on it by its hollow structure by rake teeth
In the pavement structure opened, make pavement structure obtain post bake and soften；Owing to pressurization hot blast directly acts on road
Inside face, make hot blast and pavement structure can have contact area more abundant, wider array of, in the feelings ensureing hot blast temperature
Under condition, post bake can make road surface reach good softening degree, so that rake pine process efficiency is higher.
For for heating rake teeth 19 provide high-pressure hot wind for Hot-blast Heating induction system, this system utilizes and arranges
Air stove 6 on vehicle frame 25, the high temperature and high pressure gas produced in air stove 6 is supplied to heat rake teeth 19,
By heating rake teeth 19 internal action on road surface.High temperature and high pressure gas can be produced by fuel oil burning and air mixing
Raw, fuel oil volume after combustion increases generation high temperature, with the form of high pressure mixing flue gas after mixing with the air of conveying
Output, makes road surface sufficiently be heated.
By integrated for said system on a chassis, the engagement process being not only convenient between system, also improve whole
The mobility of device, it is simple to be transferred to operation section, can utilize the mode of automatic Pilot simultaneously, makes whole rake pine
Process is automatically performed, and saves a large amount of manpower.
