Description

CURBER PAVER
TECHICAL AREA
The invention relates to the curber paver utilised on highways, tunnels, streets, ditches, country roads, and streets, as well as anywhere else a road exists.
The invention specifically relates to curber paver containing a hydraulic adjustment element that adjusts the position of the curber paver mould slides, which is used to ensure that the pressure of the hydraulic fluid to be sent to the hydraulic arms is initially adjusted according to the roughness of the floor on which the curber will be laid, and that after the hydraulic fluid is transferred to the hydraulic system according to the vertical component force coming to the hydraulic arms, the pressure of this hydraulic fluid automatically comes to the initially set pressure when pressing back on the hydraulic arms and the hydraulic arms that are used to instantly transfer these forces to the curber paver mould slides in the event that the curber paver mould slides encounter forces with a vertical component and position the curber paver mould slides according to the vertical component force coming from the ground by automatically transferring the hydraulic fluid inside to the hydraulic system with the effect of these forces.
FORMER TECHNIQUE
Globally, curber pavers are utilised on roads, tunnels, etc. Research and development on curber pavers contribute to the economy and improves the quality of work by reducing concrete waste in curber alignment and production.
The low paving quality of the curber pavers used in the current technique diminishes the quality of the curber and increases the amount of material required.
In the slides in the mould section of the current technique's curber pavers, springs are used to press the mould to the ground and create resistance against incoming vertical movements. Spring slides are incapable of adapting to the area where the curber will be installed. During placement, this condition causes concrete to escape from the right and left sides of the mould. This issue increases both concrete consumption and post-installation labour. The spring slides in the mould section of the curber pavers used in the current technique prevent the slide from positioning itself because it cannot demonstrate sensitivity when encountering an obstruction. In some instances, depending on the size of the obstruction, when these springs break, the slides become inoperable, and the curber production process comes to a halt.
In accordance with the method used in the current application in the mould section of the curber paver, excessive concrete coming out of the right and left sections of the mould during paving, the consumption of concrete, and the need for separate labour to clean the concrete that comes out later result in substantial financial losses.
In the current technique, hydraulic arms are used instead of springs to protect the curber paver mould slides from impacts from the ground. The greatest issue with these hydraulic arms is that they require constant operator-assisted adjustment to account for the unevenness of the paving area. As the roughness varies, the operator adjusts the hydraulic arms on the mould slides and then exits the slide area by adjusting two separate hydraulic levers. This situation results in both labour expenses and significant time loss.
Another issue with the current curber pavers is that they cannot make elevation adjustments and waste concrete by paving at the same rate in sloping conditions, as they are unable to respond to changes in the ground to be paved.
To solve the aforementioned issues, it was necessary to make a technological advancement.
PURPOSE OF THE INVENTION
The purpose of the invention is to ensure that concrete does not escape from the right and left sections of the mould during laying, thanks to the hydraulically operated slides in the mould section of the curber pavers, thereby reducing concrete consumption and eliminating the need for post-paving concrete removal.
A further objective of the invention is for the hydraulically operated slides in the mould section of the curber pavers to demonstrate sensitivity when they encounter an obstruction, position themselves, and continue production without halting the curber production process.
By regulating the paving quality in curber applications on roads, etc., the purpose of the invention is to improve construction quality and save material. With the help of the curber paver's sensors, an additional objective of the invention is to increase the quality of the paving by swiftly filling in any elevation gaps that suddenly appear.

DETAILED DESCRIPTION OF THE INVENTION
In Figure-1, Figure 1 depicts the curber paver (10), Figure 2 depicts the curber paver mould (20) and the curber paver mould slides (22), and Figure 3 depicts the movement of these curber paver mould slides (22) when they come into contact with a foreign object (30).
Curber pavers (10) are vehicles that are used on highways, tunnels, streets, ditches, village roads, in short, anywhere there is a road, to provide the desired form of concrete paving according to the project.
The offset bars are driven by the topographer team to adjust the level, slope, and direction of the machine in order for the curber paver (10) to work. The rope is stretched to the inserted offset rods. The sensors of the curber paver (10) are supported by the rope. The concrete mixer comes with concrete. Concrete is discharged onto a screw or conveyor. The emptied concrete is transported to the curber paver mould (20). Vibrators inside the curber paver mould (20) compress the concrete, and the curber emerges from the back of the curber paver mould (20). The invention relates to the curber paver mould slides (22) on the curber paver mould (20) used in curber pavers (10). The curber paver mould slides (22) located at the ground contact point of the curber paver mould (20) in the mould section save material by preventing concrete from coming out of the right and left sections of the curber paver mould (20) during paving.
There are hydraulic arms (21) in the mould slides (22) of the curber paver that is the subject of the invention. The pressure of these hydraulic arms (21) is adjusted once at the start, and then the hydraulic arms (21) are positioned automatically without the use of manpower. The hydraulic fluid from the hydraulic system in the curber paver (10) is pumped into the hydraulic arms (21) until the curber paver mould slides (22) make contact with the ground. After making contact with the ground, the pressure in the hydraulic arms (21) is adjusted once using the hydraulic adjustment element (40), based on the unevenness of the ground to be paved. Following this stage, the entire function is realised automatically, and the curber paver mould slides (22) that encounter the bumps without the need for human intervention transfer the vertical component force caused by the unevenness to the hydraulic arms (21) and return to their original position. There is no need for human or operator intervention during this transition. Again, the upward force exerts a pushing force on the hydraulic arms (21) during this transition, and the displacement of the hydraulic fluid in the hydraulic arms ensures a smooth transition (21). Following the transition, the displaced hydraulic fluid is automatically pumped to the hydraulic arms (21) by the effect of gravity up to the pressure set in the hydraulic adjustment element (40), and the curber paver mould slides (22) return to their original position.
As shown in Figure-3, when the curber paver mould slides (22) encounter a foreign object (30) during curber laying, the hydraulic arms (21) are activated, and the curber paver mould slides (22) continue paving by jumping over the foreign object (30) with hydraulic fluid balance automatically.
The hydraulic system in the curber paver mould slide (22) has a hydraulic adjustment element (40) connected to the hydraulic arms (21) and these hydraulic arms (21), which is used to adjust the pressure that the hydraulic fluid will create on the hydraulic arms (21) according to the roughness of the area to be laid, which is initially adjusted to prevent the need for operator assistance again.
After the hydraulic arms (21) are installed on the curber paver mould slides (22), the hydraulic fluid is pumped from the hydraulic system and the pressure bar of the hydraulic fluid pumped from the hydraulic adjustment element (40) is adjusted. The hydraulic fluid to be pumped on this hydraulic adjustment element (40) may vary according to the field conditions, the roughness of the floor to be laid on the curber, etc. The hydraulic fluid from the hydraulic system is pumped once on the hydraulic arms (21) and the pressure value is adjusted with the hydraulic adjustment element (40). Thus, the pressure balance of the hydraulic fluid on the hydraulic arms (21) is ensured. Facing a foreign object (30) without the need for any electronic automation, the curber paver mould slides (22) receive the thrust force, which is the vertical component of the foreign object (30) and position the curber paver mould slides (22) according to this force as far as the hydraulic arms (21) allow. The position of the curber paver mould slides (22) as the foreign object (30) passes over is given in Figure-3. The force from the foreign object (30) is first transferred to the curber paver mould slides (22) and then to the hydraulic arms (21) in the curber paver mould slides (22). The hydraulic arms (21) position themselves automatically according to the effect of the incoming force and provide flexibility to the curber paver mould slides (22), allowing the curber paver mould slides (22) to pass over the foreign object (30). During this transition, the hydraulic fluid pumped into the hydraulic arms (21) passes through the hydraulic adjustment element (40) area and is displaced towards the hydraulic system.
It is ensured that the hydraulic system is independent of any electronic automation and responds instantly to changes in the variable elevation difference and the location where paving will be performed on the road, etc. curber laying area, without affecting the smoothness of the curber laying.
The invention is the curber paver (10), which is utilised on highways, tunnels, streets, ditches, village roads, and streets, as well as anywhere else where there are roads. In the invention, there exist hydraulic arms (21) used to instantly transfer these forces to the curber paver mould slides (22) in the event that the curber paver mould slides (22) encounter forces and which position the curber paver mould slides (22) according to the vertical component force coming from the ground by automatically switching the hydraulic fluid inside to the hydraulic system under the influence of these forces (21) and hydraulic adjustment element (40) that adjusts the position of the curber paver mould slides (22) used to ensure that the pressure of the hydraulic fluid to be sent to the hydraulic arms (21) is initially adjusted according to the roughness of the floor on which the curber is to be laid and that the pressure of this hydraulic fluid automatically reaches the originally set pressure when the hydraulic fluid is pumped back to the hydraulic arms (21) according to the vertical component force coming to the hydraulic arms (21).
In the curber paver (10) working method used in the invention, the following steps are followed to continue the curber laying process: the hydraulic fluid is pumped into the hydraulic arms (21) in order for the curber paver mould slides (22) to contact the ground according to the surface to be laid the curber, the hydraulic pressure is adjusted from the area of the hydraulic adjustment element (40) initially according to the ground conditions before the laying process begins, the pressure set from the hydraulic adjustment element (40) is transferred to the hydraulic arms (21), and stabilization of the hydraulic fluid, the curber paver mould slides (22) in the curber paver encounter the foreign object (30) during curber paving; the curber paver mould slides (22) abut against the foreign object (30) and the vertical component force generated by the foreign object (30) is instantly transferred to the hydraulic arms (21) in order not to impair the curber paving quality; ensuring that the hydraulic fluid inside the hydraulic arms (21) passes automatically to the hydraulic system with the effect of the force; moving the hydraulic arms (21) in the upward direction; passing over the foreign object (30) and again under the influence of gravity of the hydraulic arms (21) and the hydraulic fluid initially pumped according to the pressure value set by the hydraulic adjustment element (40), again lowering the curber paver mould slides (22) to the ground and continuing the curber laying process.
In the working method of hydraulic arms (21) in curber paver mould slides (22), in order for the activation of the hydraulic arms (21) to occur without being dependent on automation, it is ensured that the first movement comes from the repulsive force, which is the vertical component of the foreign object (30), and is balanced and absorbed by the hydraulic fluid, and the last movement is taken from the gravitational force caused by the effect of gravity and the force generated by the compression of the hydraulic fluid.
Again, in the method followed in the invention, in determining the hydraulic fluid pressure value to be pumped into the hydraulic arms (21) and adjusting this pressure by the hydraulic adjustment element (40), the hydraulic fluid pressure pumped into the hydraulic arms (21) at the moment the curber paver mould slides (22) contact the ground is provided. At the moment the curber paver mould slides (22) touch the ground, the hydraulic fluid pressure in the hydraulic arms (21) is the pressure element that is referenced and adjusted by the hydraulic adjustment element (40).
All these hydraulic fluid transitions employed by the invention are performed without human intervention. In addition, it does not rely on any type of automation. The invention uses a method of mechanical automation. In accordance with the invention, it is ensured that the hydraulic fluid in the hydraulic arms (21) moves and returns to its original position. The hydraulic fluid in the hydraulic arms (21) is displaced by the vertical component force originating from the ground, and the hydraulic fluid is directed towards the hydraulic arms (21) by the hydraulic adjustment element (40) reaching the pressure value determined at the outset, thereby repositioning the hydraulic arms (21).
