Description
Technical Field
The invention relates to pavement paving equipment, in particular to a cross slope angle adjusting system and method, a spiral distributor and a paver.
Background
The paver is a common equipment for road surface construction, is a construction equipment mainly used for paving various materials of road base course and surface course, and is composed of machine body, power system, hydraulic system, running system, material conveying system, material-distributing system and ironing plate. The spiral distributor of the material distributing system is an important component of the paver and comprises a hydraulic motor, a hydraulic pump, a high-pressure oil pipe, a lifting device, a speed reducer, a chain wheel, a chain, a spiral case, a spiral shaft, spiral blades, a material baffle plate, a support pull rod and the like. When the paver works, the spiral distributor is used for transversely conveying materials and mainly used for transferring the materials to be paved from the middle to two sides, and a transfer channel is a material conveying groove formed by a material baffle plate and an ironing plate of the paver. After the material conveying groove is filled with the materials, the materials are molded into an initial pavement under the action of the ironing plate. Therefore, whether the structural performance, the parameter selection and the control mode of the spiral distributor are reasonable or not directly influences the production capacity of the spiral distributor and the construction quality of the pavement.
The spiral distributor of the existing paver is basically connected with a rear wall plate of a paver body through a spiral case and a bolt, so that the spiral distributor is integrated, the spiral distributor can be driven to integrally lift by only adjusting the lifting of a main section spiral distributor so as to drive the extending sections of the two sides of the paver body to integrally lift, and the lifting adjusting device is provided with ratchet wrench mechanical adjustment, hydraulic control adjustment and the like, so that the ratchet wrench mechanical adjustment is more. When the paver works, the ground clearance of the whole spiral distributor is adjusted well through a ratchet wrench before paving according to the requirement of paving thickness so as to achieve smooth flowing and uniform distribution of materials in a material conveying groove; if the stroke of the hydraulic oil cylinder is adjusted, the control button on the operating platform is used for adjusting the stroke of the left lifting oil cylinder and the right lifting oil cylinder of the spiral distributor to adjust the ground clearance of the spiral distributor when the stroke needs to be adjusted, so that the paving thickness requirement is met. However, because the screed plate is in floating connection through the large arm oil cylinder in the paving process, when the paving thicknesses on two sides of the screed plate are inconsistent, the screed plate and the road base layer have a cross slope angle alpha. Along with the progress of paving, the cross slope angle alpha probably still can be continuous change, if the spiral tripper still horizontal arrangement does not have the cross slope contained angle with road surface basic unit, because the material of demand is more in the great one side of thickness that paves, the material can overflow the surface that the striker plate caused the material to pile up the place ahead of striker plate, and because the demand material is less in the less one side of thickness that paves, the extension section spiral can not play fine branch material effect. When the hydraulic telescopic oil cylinder is used for adjustment, the cross slope angle alpha of the screed plate may change at any time during paving, an operator of the paver cannot accurately judge when the cross slope angle of the spiral distributor needs to be adjusted, and the operator cannot accurately grasp the size of the cross slope angle of the spiral distributor.
Therefore, it is necessary to design a cross slope adjusting system and method, so that the cross slope angle of the spiral distributor changes with the change of the cross slope angle of the ironing plate, which can ensure the smooth horizontal flow of the material in the material conveying tank without material overflow, and can also ensure the material distributing function of the extension section spiral distributor, and has high practical value, time saving and labor saving.

The following is a more detailed description of the preferred embodiments of the invention, but not intended to limit the invention, as illustrated in the accompanying drawings.
As shown in fig. 1 and 2, a cross slope angle adjusting system according to an embodiment of the present invention is applied to a paving machine, and includes: the device comprises a first transverse slope sensor 101, a second transverse slope sensor 102 and a controller 103, wherein the first transverse slope sensor 101 and the second transverse slope sensor 102 are electrically connected with the controller 103, the controller 103 is electrically connected with an electromagnetic valve for controlling a telescopic adjusting oil cylinder of the spiral distributor, and the inlet and outlet of hydraulic oil of an oil inlet and outlet of the telescopic adjusting oil cylinder are controlled by controlling the electromagnetic valve to be powered on or powered off so as to control the telescopic adjusting oil cylinder to stretch. The first cross slope sensor 101 is used for acquiring a cross slope angle alpha of an ironing plate of the paver in real time; the second cross slope sensor 102 is used for acquiring the cross slope angle beta of the spiral distributor in real time. The first cross slope sensor 101 transmits a cross slope angle alpha of an ironing plate of the paver acquired in real time to the controller 103, the second cross slope sensor 102 also transmits a cross slope angle beta of the spiral distributor acquired in real time to the controller 103, the controller 103 has a comparative analysis function, after the controller 103 compares the cross slope angle alpha with the cross slope angle beta, an electric signal (a voltage signal or a current signal) is sent to an electromagnetic valve of the telescopic adjusting oil cylinder, the electromagnetic valve controls hydraulic oil flowing of an oil inlet and an oil outlet of the telescopic adjusting oil cylinder so as to stretch the telescopic adjusting oil cylinder, the inclination direction of the spiral distributor is the same as the inclination direction of the ironing plate, and the cross slope angle beta of the spiral distributor is the same as the cross slope angle alpha of the ironing plate.
The first cross slope sensor 101 and the second cross slope sensor 102 in this embodiment are both angle sensors, and can acquire a cross slope angle value in real time.
The spiral distributor disclosed by the invention as shown in fig. 3 comprises a hydraulic left telescopic adjusting cylinder 11, a hydraulic right telescopic adjusting cylinder 12, a left driving device 21, a right driving device 22, a left spiral striker plate 31, a right spiral striker plate 32, a supporting device 4, a frame 5, a spiral case 6, a left main section spiral 71, a right main section spiral 72, a left spiral hanging seat 81, a right spiral hanging seat 82, a left extension section spiral 91 and a right extension section spiral 92. As shown in figure 3, the spiral distributor is connected with the frame 5 through a left telescopic adjusting oil cylinder 11 and a right telescopic adjusting oil cylinder 12, and the ground clearance of the spiral distributor can be adjusted by adjusting the strokes of the left telescopic adjusting oil cylinder 11 and the right telescopic adjusting oil cylinder 12. The left extension helix 91 and the right extension helix 92 are connected to the frame 5 by the support means 4. The left extension section spiral 91 is connected with the left spiral striker plate 31 through the left spiral hanging seat 81, and the right extension section spiral 92 is connected with the right spiral striker plate 32 through the right spiral hanging seat 82.
The spiral distributor of the present invention further comprises the above described cross slope angle adjusting system, wherein the second cross slope sensor 102 is disposed on the spiral casing 6, in this embodiment, the second cross slope sensor 102 is disposed at the middle position of the upper portion of the spiral casing 6. In fact, the second traverse slope sensor 102 can obtain the traverse slope angle β of the spiral distributor in real time as long as it is arranged on the spiral distributor, and there is no special requirement for the specific arrangement position. But is generally disposed on the screw housing 6 in consideration of convenience of installation and undisturbed detection. Since other parts of the spiral distributor are generally in direct contact with the paving material, the second slope sensor 102 disposed on other parts may be buried in the paving material, which may affect the accuracy of the detection result.
Further analysis when the thickness of the pavement being formed is not uniform on both sides, as shown in fig. 4, the base pavement layer 104 is horizontal, while the paved pavement forming layer 105 is non-uniform on both sides, i.e., thicker on the left and thinner on the right in fig. 4. Because the screed plate of the paver is connected with the large arm, the cross slope angle alpha of the screed plate is adjusted by controlling the telescopic stroke of the large arm oil cylinder, and the paving requirement is met. Before paving, the requirement of paving thickness is met by adjusting the proper ground clearance of the spiral distributor. When the height of shaping road surface both sides is highly inconsistent, if keep spiral tripper and road bed level, the material demand of the thick one side of paving will be satisfied this moment, must improve the terrain clearance of spiral tripper, guarantee to pave the material supply ability of thick one side, nevertheless at the thin one side of paving, because the material demand is less, spiral tripper ground clearance is too high, causes helical blade to keep away from the material and can not be the even and smooth width direction that will pave with the material branch. Certainly, under this condition, if in order to satisfy the material smooth cloth that paves the less direction, can suitably reduce the ground clearance of spiral tripper, another problem has also appeared simultaneously, that is to pave thick one side, because the material demand is too much, the helical blade is fully buried in the mixture (or called the material that paves), probably can't accomplish to divide the material and appear piling up of mixture, divides the material too slowly or the mixture spills over phenomenon such as on the surface of spiral striker plate.
The cross slope angle adjusting system is arranged, so that the cross slope angle beta of the spiral distributor can be always consistent with the cross slope angle alpha of the ironing plate, and smooth paving is guaranteed. The following describes the specific operation process.
Before the paver works, constructors control the direction and the thickness of a paved road surface by arranging steel wires and the like on two sides of the road surface to be paved. According to the investigation, design and concrete condition of roadbed, the height of two sides of the paved road surface can be determined. The spiral distributor is horizontally arranged, and the proper height of the spiral ground is preset according to the paving thickness requirement. A first cross slope sensor 101 is arranged on a paver screed plate, a second cross slope sensor 102 is arranged on a spiral distributor, the first cross slope sensor 101 and the second cross slope sensor 102 are electrically connected with a controller 103, and angle values acquired by the first cross slope sensor 101 and the second cross slope sensor 102 are transmitted to the controller 103. The screed plate of the paver is connected with the frame through the lifting oil cylinder, the paving requirement can be smoothly met through the leveling system, and a cross slope angle alpha is formed between the bottom surface of the screed plate and a road base layer. The more material of thick one side demand of paving this moment, and the material demand of the thin one side of paving is less relatively, still keeps initial level setting if the spiral tripper, will lead to the thick one side material of paving to spill over the surface of spiral striker plate, and the thin one side of paving can not play fine branch material effect because the less extension spiral of material demand. Due to the additional arrangement of the cross slope angle adjusting system, the first cross slope sensor 101 can transmit the cross slope angle alpha of the ironing plate to the controller 103 in real time, and the second cross slope sensor 102 arranged on the spiral distributor can transmit the cross slope angle beta of the spiral distributor to the controller 103 in real time. The controller 103 compares whether the cross slope angle beta of the spiral distributor is the same as the cross slope angle alpha of the ironing plate, if so, the left telescopic adjusting oil cylinder 11 and the right telescopic adjusting oil cylinder 12 keep the set telescopic stroke unchanged, and the paving is continued; if the cross slope angle beta of the spiral distributor is different from the cross slope angle alpha of the ironing plate, the controller 103 sends control signals to the electromagnetic valves for controlling and adjusting the left telescopic adjusting oil cylinder 11 and the right telescopic adjusting oil cylinder 12, and the telescopic strokes of the left telescopic adjusting oil cylinder 11 and the right telescopic adjusting oil cylinder 12 are adjusted, so that the cross slope angle beta of the spiral distributor can be adjusted, the cross slope angle beta of the spiral distributor can be adjusted through the strokes of the telescopic adjusting oil cylinders until the cross slope angle beta is the same as the cross slope angle alpha, and the inclination directions of the spiral separator and the ironing plate are also the same. Therefore, by arranging the cross slope angle adjusting system, the cross slope angle of the spiral separator is adjusted in real time according to the cross slope angle of the ironing plate, namely the cross slope angle beta of the spiral distributor is kept to be the same as the cross slope angle alpha of the ironing plate all the time, smooth flowing and uniform distribution of materials in the trough can be ensured, and smooth spreading is guaranteed. Through setting up the cross slope angle governing system, make the cross slope angle beta of spiral tripper change along with the change of the cross slope angle alpha of screed, both keep unanimous automatically all the time, so both can guarantee the smooth circulation of mixture material in spiral tripper both sides and do not the flash, also can be fine guarantee to extend the branch material effect of section spiral, guaranteed also that the material can not influence the process of paving because of too much or too little simultaneously. Has high practical value.
The invention also discloses a cross slope angle adjusting method, which comprises the following steps:
the method comprises the following steps that a first cross slope sensor acquires a cross slope angle alpha of an ironing plate of the paver in real time and transmits the cross slope angle alpha to a controller;
the second cross slope sensor acquires the cross slope angle beta of the spiral distributor in real time and transmits the cross slope angle beta to the controller;
the controller analyzes and compares the cross slope angle alpha and the cross slope angle beta, and controls the left telescopic adjusting oil cylinder and/or the right telescopic adjusting oil cylinder of the spiral distributor to stretch according to the analysis and comparison result so as to adjust the spiral distributor to enable the inclination direction of the spiral distributor to be the same as that of the ironing plate, and the cross slope angle beta is equal to the cross slope angle alpha.
Since the screw shafts of the paver have different permissible ground clearance ranges for paving under different conditions, the ground clearance of the screw shafts should be adjusted within the permissible ground clearance ranges. Generally, the allowable ground clearance range of the spiral shaft is related to factors such as paving thickness and paving width, and needs to be determined according to actual conditions. Studies have shown that when large thickness paving (paving thickness of 350mm or more) is carried out, the helical blades are sometimes buried, but generally the helical blade diameter 2/3 is buried in the mix. And usually the lowest elevation of the blade is between 80mm and 150mm, and the allowable elevation range of the screw shaft can be obtained according to the radius of the blade and the lowest elevation of the blade. According to the allowable ground clearance range of the screw shaft, the travel ranges of the left telescopic adjusting cylinder 11 and the right telescopic adjusting cylinder 12 need to be set in advance to ensure that the ground clearance of the screw shaft is within the allowable ground clearance range.
Before paving, the ground clearance of the screw shaft is set within the allowable ground clearance range, but as paving progresses, the paving thickness of the paved road surface changes continuously, and the ground clearance of the screw shaft deviates from the allowable ground clearance range.
Therefore, the adjusting method of the invention needs to firstly judge whether the ground clearance of the spiral shaft of the spiral distributor is in the allowable ground clearance range, and if the ground clearance of the spiral shaft of the spiral distributor is beyond the allowable ground clearance range, the controller controls the left telescopic adjusting oil cylinder and the right telescopic adjusting oil cylinder to simultaneously extend and retract so as to adjust the ground clearance of the spiral shaft to the allowable ground clearance range.
And when the ground clearance of the spiral shaft is adjusted to be within the range of the permitted ground clearance and the cross slope angle alpha is larger than or smaller than the cross slope angle beta, the controller continuously controls the left telescopic adjusting oil cylinder and/or the right telescopic adjusting oil cylinder to stretch until the cross slope angle beta is equal to the cross slope angle alpha.
Because there are many different situations in the positional relationship of the spiral distributor and the ironing plate and the cross slope angle relationship between the spiral distributor and the ironing plate, the following description is provided in detail with reference to the accompanying drawings: first, it should be noted that: between the two dotted lines in fig. 5 to 13, i.e. the upper limit axial line position 2011 and the lower limit axial line position 2012, is the allowable ground clearance height range 202, the screw shaft should be located in the allowable ground clearance height range 202 and parallel to the dotted line where the upper limit axial line position 2011 and the lower limit axial line position 2012 are located, that is, the axis of the screw shaft at the highest position cannot exceed the upper limit axial line position 2011, and the axis of the screw shaft at the lowest position cannot be lower than the lower limit axial line position 2012.
