Definitions

  • the present invention relates to an apparatus for applying a joint or crack sealant, in particular to road surfaces.
  • the coatings in question may for example be of the hydrocarbon type or of the hydraulic concrete type, and the joints which should be sealed may be in particular the joints ordinarily separating, at regular intervals, two elements neighboring the concrete coating. .
  • the cracks that should be plugged they may be those that arise, especially on hydrocarbon coatings, due to the expansion or contraction constraints generated in the coating by temperature variations, ground movements or other factors.
  • sealant it may be any known product intended for this use, for example products based on bitumen or tar mixed with elastomers, and products applied hot or cold , but especially hot products whose temperature at the time of application may be - to fix ideas - of the order of 250 ° C maximum, temperature which should be within a range of about 30 ° C.
  • the invention relates more particularly to an apparatus for applying a sealant to joints or cracks, in particular on road surfaces, comprising a product injection nozzle connected to a source of sealant under pressure and at an appropriate temperature carried by self-propelled or towed auxiliary equipment, by a flexible pipe provided with an outer jacket in which a thermoregulated fluid for maintaining the temperature of said product can circulate; handles allowing an operator walking on the ground to guide and bring said nozzle, either in the lowered position for which its orifice opens out in the immediate vicinity of the covering, or in the raised position; a valve for adjusting the flow rate of the product arriving at said nozzle, and a control member for said valve.
  • this device does not include scraping means, to make the surface of the joint united and to level it with the surface of the coating, which is another serious drawback.
  • US-A-3 841 527 describes a device of the same general type, but having no means of pressing on the coating, allowing the operator to precisely adjust the position of the product injection nozzle, which is directly held by hand.
  • US-A-3 050 260 describes a device intended for tracing painted marking strips on road surfaces, and not a device for plugging cracks. Such an apparatus does not have a scraper shoe, and the product outlet nozzle is remote from the ground, which makes it completely unsuitable for dispensing a crack sealant.
  • US-A-2420410 describes a device for plugging cracks with a scraper shoe, but the product dispensing nozzle is integral with the vehicle carrying the tank, which makes the dispensing device itself (the nozzle and its accessories) extremely difficult to handle, especially in the horizontal direction; this is a serious drawback when it is necessary to plug non-linear cracks or cracks, as is frequently the case.
  • US-A-1 990 545 describes an apparatus having the same drawbacks as the previous one, with regard to precision; the outlet nozzle is associated with a scraper, but here again it is a marking device, and not a device for plugging cracks.
  • US-A-1,733,841 describes a device for plugging cracks with an equalizing shoe, but it is this device itself which also serves as a vehicle for transporting the product, since it carries the tanks. This arrangement makes the device heavy, bulky and a delicate and tiring handling for the operator.
  • US-A-1,924,636 describes a device of the same general type as the previous one, but without an equalizing device.
  • US-A-2530777 describes a device for plugging cracks in which, again, the dispensing nozzle is secured to the vehicle carrying the product reservoir; the operator, too, is carried by this vehicle.
  • US-A-3 206 125 describes an apparatus for plugging cracks which has the same kind of drawback as that of US-A-3 841 527.
  • US-A-2,161,488 describes an apparatus carried by a vehicle, generally having the same drawbacks as that of US-A-2,530,777.
  • US-A-1750104 further describes a device for filling cracks carrying the reservoir, and having the same kind of drawbacks as, for example, that of US-A-1,924,636.
  • the object of the present invention is to remedy all of these drawbacks and shortcomings of the prior art, and to obtain an apparatus of the general type described at the start, but which, moreover, is particularly light and handy, easily allows precise filling of cracks. , without particular fatigue for the operator and without downtime, and which, moreover, makes it possible to obtain smooth joints and perfectly level with the coating to be repaired.
  • This very handy device will allow the operator to easily position the injection nozzle exactly over the joint or crack to be filled and to follow its path precisely, just as it will allow him to immediately order i ' arrival of the sealant at the nozzle or interruption of the flow, as required.
  • the wheel can be used as a stand when the device is no longer in use.
  • control member of the valve for adjusting the flow rate of arrival of the product at the injection nozzle it can advantageously be carried by one of the aforementioned handles of the device and be connected to the valve by a Bowden type cable, the traction of which is adapted to open the valve, the closing thereof being also ensured by a return spring.
  • the chassis of the device can also carry, in front of the nozzle - having regard to the normal direction of advance for the device - a compressed air blowing nozzle, the flow of which can optionally be controlled from the other handle. , with possibly also, behind the nozzle, means for projecting gravel or the like.
  • an improvement of the device could also consist in that said chassis further carries a motor, preferably hydraulic, coupled to said wheel, or to at least one of the wheels when the chassis carries several.
  • the chassis of the device has been generally referenced in 1.
  • This chassis can be made up of welded flat bars, referenced in 2, braced in 3, to which is fixed, by means of a clevis 4 and welded rods 5, a rolling eye 6.
  • the upper end of the chassis 1 carries welded handles 7, and its opposite end is shaped as a scraper shoe 8 having the general shape of a triangle open towards the front, having regard to the normal direction of movement of the device, shown by arrow F.
  • an injection nozzle 9 In the apex angle of said scraper shoe 8 is fixed an injection nozzle 9, the outlet of which opens in the immediate vicinity of the surface of the coating 10 when the apparatus occupies the position shown in the figure, for which said scraper shoe 8 carries on the coating.
  • the injection nozzle 9 is connected to a source of sealant under pressure and at an appropriate temperature (not shown but carried for example by a self-propelled auxiliary device), by means of a flow control valve 11 and a flexible supply line 12.
  • Line 12 is provided with an outer jacket in which, under the action of a pump also carried by said self-propelled apparatus, can circulate a thermoregulated fluid for maintaining the temperature of the sealant, which fluid can be constituted for example with oil.
  • the oil return line has been designated at 13.
  • the lines 12 and 13 are suitably insulated, for example + asbestos.
  • the flow control of the regulating valve 11 can be carried out from a control handle 14 carried by one of the handles 7 and connected by a cable of the Bowden type 15 to the opening or closing lever 16 of the adjusting valve 11.
  • the opening of the valve being controlled by a pressure exerted on the lever 14, its closing can be ensured by a return spring 17 stretched between the lever 16 and a welded support 18.
  • another spacer 19 of the scraper shoe 8 carries a compressed air blowing nozzle 20 connected, via a flow control valve 21 and a flexible pipe 22, to an air source tablet also carried by said self-propelled auxiliary equipment.
  • the adjustment of the opening or the closing of the valve 21 can be ensured by another control lever 23, carried by the other handle 7 and connected, by a Bowden type cable 24 , to a lever 25 of the valve, the valve being closed by another return spring, referenced at 26.
  • the apparatus could also carry, behind the nozzle 9, means for projecting gravel or the like, preheated or not, just as the chassis could also carry a motor, preferably hydraulic, coupled to the wheel 6.
  • the operator grasping the apparatus by the handles 7, and walking backwards in the direction of the arrow F, will be able to easily observe the superposition of the injection nozzle 9 and of the joint or of the crack to be filled 27, and also correct filling of the joint by appropriately adjusting the pressure exerted on the adjusting handle 14, controlling the flow of arrival of the sealant under pressure at the nozzle 9, and possibly by adjusting the speed of its operation, this to avoid excess product arrival inside the scraper shoe 8 or, on the contrary, a lack of product.
  • a pressure exerted on the control handle 23 will allow cleaning of the seal 27 or similar crack to be filled, before injection of the sealant.
  • running wheel 6 can also serve as a stand, when the device is not in use.
  • the scraper shoe 8 could be opened in the opposite direction, it that is to say on the side opposite to the direction indicated by the arrow F, the device then being designed to move in this opposite direction.
  • the compressed air blowing nozzle 20 would be placed in front of the sealant injection nozzle 9, and on the contrary the spray nozzle for gravel or the like, preheated or not, would be placed behind the nozzle 9 (practically at the location that the nozzle 20 currently occupies in the figure).
