In road construction, roads and paths are made from various materials such as asphalt, concrete, paving, large formats or from unbound material (e.g. gravel) (top layer and base layer). For larger construction projects, the construction is carried out using a road paver for asphalt roads or a concrete paver or slipform paver for concrete roads. Small construction projects and repairs are often carried out manually.

• • Wahl der eingesetzten Maschinen,
• • Wahl des eingebauten Materials,
• • Beachtung der Umweltbedingungen (Temperatur, Regen etc.),
• • ausreichende Verdichtung bei der richtigen Asphalttemperatur.

Important points in road construction are:

• • Choice of machines used,
• • Choice of installed material,
• • Consideration of environmental conditions (temperature, rain, etc.),
• • sufficient compaction at the correct asphalt temperature.

• Die erste ist einen Kocher auf ein Trägerfahrzeug aufzubauen. Das bedeutet der Vergusskocher ist stationär und wird mittels des Trägerfahrzeugs (LKW, Anhänger usw.) auf der Baustelle bewegt. Diese Art ist sehr ungünstig, da die zu vergießende Person mit dem Fahrer des Trägerfahrzeugs kommunizieren muss. Über die Entfernung gestaltet sich das vor allem in geräuschbelasteter Umgebung problematisch und erfordert eine sorgfältige Arbeitsweise und ein gut eingespieltes Team auf der Baustelle.

As the above assessment of the state of the art shows, differently designed devices and mobile systems for individual or multiple work processes are known. The two most commonly used devices in practice to carry out joint filling on the construction site with a hose system are the following:

• The first is to install a cooker on a carrier vehicle. This means that the casting cooker is stationary and is moved around the construction site using the carrier vehicle (truck, trailer, etc.). This method is very unfavorable because the person doing the casting has to communicate with the driver of the carrier vehicle. Over a distance, this is particularly problematic in noisy environments and requires careful working methods and a well-coordinated team on the construction site.

The second type of hose or lance casting is a self-propelled trailer that is uncoupled from the towing vehicle on the construction site and can then be moved independently by an operator on the construction site, as described in the applicant's unpublished patent application EN 10 2024 001 092.0 described. Communication is good here, as the grouting operator works close to the driver. The disadvantage is the high cost of purchase. Accordingly, in practice there is no inexpensive mobile device for joint filling and repair that is equally suitable for small and medium-sized construction projects, makes the work easier for the user and is easy to transport. This is particularly important because the road construction machinery industry is seen as a progressive, development-oriented industry that quickly takes up improvements and simplifications and puts them into practice.

problem

Compared to the known devices, the innovation is based on the task of further developing them in such a way that the user is provided with a device for asphalt and/or joint repair that is easy to transport and operate.

Solution

• • ein Fahrgestell, welches mindestens drei Räder aufweist,
• • ein Hebewerk zum Anheben und Absenken der Räder,
• • einen Fahrantrieb für mindestens ein Rad,
• • eine Lenkung für mindestens ein Rad und
• • einen Aufschmelzkocher mit Förderpumpe

derart, dass im Fahrbetrieb der Benutzer den Vergusskocher zur Fugenreparatur steuert und lenkt.This problem is solved, according to claim 1, in that the casting cooker has:

• • a chassis with at least three wheels,
• • a lifting mechanism for raising and lowering the wheels,
• • a drive for at least one wheel,
• • steering for at least one wheel and
• • a melting cooker with feed pump

in such a way that the user controls and steers the grouting cooker for joint repair during operation.

Beneficial effects of the innovation

The new device enables self-sufficient and mobile joint grouting on the construction site. The device can be easily loaded using the (self-)driven drive. The device can be easily lowered at the loading location using the liftable chassis/chassis and then stands on the chassis. On the construction site, the device is self-propelled and can be used in the same way as a grouting trailer. In addition, the extremely compact design and low weight are a great advantage, as the device can be easily transported in trucks or vans as well as trailers. One, two or three wheels can be lowered, particularly for loading the device or when driving over obstacles such as curbs or similar, so that the ground clearance under the chassis is increased.

Further embodiments of the invention

In a further development of the innovation, according to claims 2 and 3, the steering is designed as a steering wheel which is arranged laterally on the casting cooker and which pivots at least one wheel via a steering gear, wherein the chassis has two wheels arranged coaxially at a distance from one another and the third wheel is steerable.

This new development has the advantage of enabling flexible and fast steering on the construction site, meaning that it can also be used for the quick, cost-effective repair of "wild" cracks. Another advantage is that the user does not stand in the lane but to the side of the grouting unit (reduced safety risk) and can safely observe the grouting of the joint or crack.

In the embodiment of the innovation, according to protection claim 4, the lifting mechanism, the travel drive and the feed pump have hydraulically operated hydraulic cylinders mounted on the chassis.

This innovative design has the advantage that the requirements of rough operation are met by means of the hydraulic cylinders. In particular, for loading the casting cooker or when driving over obstacles such as This can be raised hydraulically when the melting cooker is placed on a curb or similar, so that the ground clearance under the melting cooker is increased. The additional ground clearance makes it possible to load the melting cooker over very steep ramps and also to seal joints on sloped roads. In particular, this allows the fill level in the melting cooker to be corrected to the horizontal. When the desired position is reached, the hydraulic cylinders are held in this position by means of a locking valve.

In a further development of the innovation, according to claim 5, the chassis is constructed from a tubular frame.

This innovative development has the advantage that the chassis can be built up and expanded cost-effectively and enables a compact and robust design, resulting in a longer service life, which is desirable and important under the harsh conditions of road construction.

In an embodiment of the innovation, according to claims 6 and 7, the chassis has a handlebar arranged on the front side of the device, wherein the handlebar is adjustable in length and can be coupled to the steerable wheel.

This innovative design has the advantage that even without operating the device, an inexperienced user can easily and quickly control the steering when moving the device.

1 until 7 show an embodiment of a casting cooker V according to the innovation. In detail, the casting cooker V has a chassis F with at least three wheels R1, R2, R3. Furthermore, a lifting mechanism H for raising and lowering the wheels R1, R2, R3 of the chassis is integrated in the chassis F.

5 the landing gear in the retracted position FAE and 6 the chassis in the extended position FA1. The chassis F preferably has two wheels arranged coaxially at a distance from one another, wheels R1, R2, hereinafter referred to as individual wheels, which are pivotably mounted on the chassis by the lifting mechanism H by means of telescopic cylinders Z. The third wheel R3 is steerable and can be extended and retracted by means of telescopic cylinders Z of the lifting mechanism H, which are designed as lifting cylinders.

Furthermore, the casting cooker V has a drive FA for at least the steerable wheel R3. The steering L for this wheel R3 is designed as a steering wheel L, which is arranged on the side of the casting cooker V and which pivots the wheel R3 via a steering gear LG. Furthermore, the chassis F has a steering rod LS arranged on the front side of the device V (see 2 ), which is adjustable in length and can be coupled to the steerable wheel R3.

1 until 4 show the arrangement of a melting cooker K, which is equipped with a feed pump, in the rear upper area of the casting cooker V. The melting cooker K enables fast and material-friendly melting and can have a safety filling flap with agitator stop. An automatic agitator stop is also provided when the flap is open. This enables simple and ergonomic loading of the melting cooker K, preferably with casting compound cubes, handling is safer and the risk of accidents is significantly reduced. A special boiler design for indirect heating via hot air protects the casting compound from thermal overload and ensures even, rapid melting. Automatic temperature control of the melting cooker K ensures constant and precise working temperatures.

Furthermore, the melting cooker K is connected to the heating element by means of an electrically heated hose line ES with a hand-operated application tool A for filling the casting compound into the joint (see 7 ). In conjunction with the suction mode of the feed pump, cleaning of the hose line ES is hardly necessary. Furthermore, the V grouting cooker can be equipped with a hot air lance, the ignition of which, the gas supply from propane gas bottles via a control panel, as well as that of the grouting pump can be set by the user. This can ensure both rapid drying of the joint and rapid preheating. The ES grouting hose can also be suspended from a push rod hose holder KR with spring suspension, which relieves the user of weight and does not restrict mobility (see 7 , with the hydraulic lifting mechanism H in the retracted position).

The drive FA is infinitely variable and has, in particular, a continuously variable forward gear and a reverse gear. The steering L can also be adjusted from easy to turn for quick steering movements to more difficult to turn (for straight cuts). The drive FA is also equipped with a hydraulic brake, which further improves safe transport and stability when the casting cooker V is not in use.

The chassis F has at least one crane eye KÖ for safe loading and unloading of the casting cooker V. 1 until 4 show four crane eyes KÖ fastened to the top of the tubular frame of the chassis F by force or form-fitting. In addition, the chassis F of the casting cooker V can have forklift lugs S /open tubular frame R for easy loading.

Finally, the casting cooker V can have an LED light tower with rotating lights, which is controlled by the user from the control panel B. For this purpose, a separate power supply is provided for controlling valves, heating the hose line and the LED light tower/lighting, whereby the control panel B has an emergency stop switch.

The innovation is not limited to the combinations of features defined in claim 1, but can also be defined by any other combination of specific features of all the individual features disclosed. This means that in principle practically every individual feature of claim 1 can be omitted or replaced by at least one individual feature disclosed elsewhere in the application, i.e. the innovation is only limited by the claims.
