Description

Technical Field

[0001] The utility model relates to the technical field of road engineering machinery, in particular to a smoothing device with adjustable angle. Background Art

[0002] The leveling device is the core working device of the slipform paver. By adjusting the height of the leveling beam and the front and rear legs of the slipform paver, the slurry can be rolled evenly without aggregate lifting. It can level and shape the surface of the cement slurry pavement at a certain angle, raise the cement slurry surface, and repair the pores and defects on the surface. The operating function and quality of the paver are ultimately achieved by the leveling device. When the paver is paving, the arch angle of the leveling device directly acts on the paved road surface, which has a huge impact on the road construction quality.

[0003] However, most of the flattening devices on the market still use manual crown adjustment, which has obvious limitations:

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0023] The angle-adjustable flattening device of the utility model is described below in conjunction with the accompanying drawings.

[0024] like Figure 1-Figure 2 As shown, the angle-adjustable flattening device of the embodiment of the utility model may include two symmetrically arranged fixing frames 1, an angle adjustment component 2, two flattening mechanisms 3, two articulated shaft seats 4 and two inclination sensors 5.

[0025] The two fixing frames 1 are detachably connected to the slipform paving machine frame (not shown in the figure).

[0026] It should be noted that the slipform paver frame described in this embodiment is prior art and will not be described in detail here.

[0027] The angle adjustment assembly 2 may include a first height adjustment mechanism 20 , a second height adjustment mechanism 21 , two inclination adjustment mechanisms 22 , a third height adjustment mechanism 23 , a solenoid valve group 24 , and an electrical control cabinet 25 .

[0028] The first height adjustment mechanism 20 and the second height adjustment mechanism 21 are respectively fixed on the corresponding fixing frame 1 , and one end of the two first height adjustment mechanisms 20 and the second height adjustment mechanism 21 are respectively detachably connected to the corresponding flattening mechanism 3 .

[0029] One ends of the two inclination adjustment mechanisms 22 are respectively connected to the corresponding first height adjustment mechanisms 20 , and the other ends of the two inclination adjustment mechanisms 22 are respectively in contact with the corresponding flattening mechanisms 3 .

[0030] The solenoid valve group 24 is respectively connected to the first height adjustment mechanism 20, the second height adjustment mechanism 21, the inclination adjustment mechanism 22 and the third height adjustment mechanism 23 through multiple hydraulic high-pressure rubber pipelines. The solenoid valve group 24 is also connected to the liquid supply oil circuit (not shown in the figure) on the main machine of the slipform paver through hydraulic high-pressure rubber pipelines.

[0031] It should be noted that the liquid supply oil circuit on the main machine of the slipform paver described in this embodiment may include an oil tank, an oil pump, an overflow valve, etc. Since it is a prior art, it will not be described in detail here.

[0032] The electrical control cabinet 25 is connected to the electromagnetic valve group 24 and the inclination sensor 5 respectively.

[0033] It should be noted that the electrical control cabinet 25 described in this embodiment integrates a programmable logic controller (Programmab le Logi c Controller), a display and an operation panel. At the same time, the electrical control cabinet 25 can also be connected to an external host computer, and the preset road crown transverse slope (the angle between the working surface of the flattening mechanism and the formed road surface) can be entered into the electrical control cabinet 25 in advance. The electrical control cabinet 25 can fine-tune the first height adjustment mechanism 20, the second height adjustment mechanism 21, and the third height adjustment mechanism 23 through the solenoid valve group 24 according to the preset road crown transverse slope.

[0034] Among them, the cross slope of the road humps refers to the road surface on the cross section of the road, which is high in the middle and low on both sides, with a certain slope. Its function is to facilitate the lateral drainage of the road surface. The cross slope of the road humps is generally 1.5% to 4.0%, which varies with the type of road surface. The cross slope of high-grade road surface is small, and the cross slope of low-grade road surface is large. The road humps slope depends on the type of road surface: asphalt concrete and cement concrete road surface is 1% to 2%; other black road surface, neat stone road surface is 1.5% to 2.5%; semi-neat stone, irregular stone road surface is 2% to 3%; crushed, gravel and other granular road surface is 2.5% to 3.5%; low-grade road surface is 3% to 4%.

[0035] Adjacent ends of the two smoothing mechanisms 3 are respectively fixedly connected with articulated shaft seats 4 , and the two articulated shaft seats 4 are pivotally connected to each other. Two inclination sensors 5 are respectively arranged on the smoothing mechanisms 3 , and the inclination sensors 5 are arranged adjacent to the articulated shaft seats 4 .

[0036] Specifically, taking cement concrete road as an example, the transverse slope of the road crown of cement concrete road is 1% to 2%. During the actual operation, the inclination angle of the smoothing mechanism 3 is monitored in real time by using the inclination sensor 5, and this key data is quickly transmitted to the electrical control cabinet 25. The electrical control cabinet 25 then accurately calculates the horizontal arch angle between the two smoothing mechanisms 3 based on the received data, and fine-tunes the first height adjustment mechanism 20, the second height adjustment mechanism 21, and the third height adjustment mechanism 23 through the solenoid valve group 24 in real time, and changes the horizontal arch angle between the two smoothing mechanisms 3 in real time, so that the transverse slope of the road crown of the cement concrete road after forming is always within the range of 1% to 2%, meeting the pavement engineering standards and quality requirements.

[0037] At the same time, the device also gives the operator great flexibility. The relevant personnel can also manually operate the electrical control cabinet 25 to control the inclination adjustment mechanism 22 through the solenoid valve group 24, and then fine-tune the elevation angle of the smoothing mechanism 3, effectively adjust the amount of cement slurry rubbed up, and further improve the surface quality of the cement formed pavement.

[0038] Therefore, the device can adjust the vertical elevation angle of the smoothing mechanism 3 and the horizontal arch angle of the two smoothing mechanisms 3 in real time according to the real-time road conditions through a combination of manual and automatic methods, thereby controlling the size of the rolled slurry roll and the arch angle of the road surface, meeting the high-quality paving requirements, being simple to operate, saving time and effort, and greatly improving work efficiency.

[0041] The second height adjustment mechanism 21 may include a fourth connecting frame 210, a second hydraulic cylinder 211 and a second slide 212, wherein the fourth connecting frame 210 can be detachably connected to the corresponding fixed frame 1, the second hydraulic cylinder 211 is fixed on the fourth connecting frame 210, and one end of the second hydraulic cylinder 211 is slidably connected to the second slide 212, and the second slide 212 is fixed on the corresponding flattening mechanism 3.

[0042] Specifically, the electrical control cabinet 25 can control the telescopic distance of the piston rods in the first hydraulic cylinder 201 and the second hydraulic cylinder 211 through the solenoid valve group 24 according to the data signal transmitted by the inclination sensor 5 to change the inclination angle of the corresponding flattening mechanism 3 .

[0045] Specifically, relevant personnel can control the electrical control cabinet 25 to control the telescopic distance of the piston rod in the third hydraulic cylinder 221 through the solenoid valve group 24. The piston rod in the third hydraulic cylinder 221 can push the smoothing mechanism 3 to rotate through the fifth connecting frame 222 and the rolling stop wheel 223, thereby changing the elevation angle of the smoothing mechanism 3.

[0046] In one embodiment of the present invention, Figure 1 As shown, the third height adjustment mechanism 23 may include a fourth hydraulic cylinder 230 and two symmetrically arranged mounting seats 231 .

[0047] The two mounting seats 231 are respectively fixed on the corresponding flattening mechanisms 3 , and the mounting seats 231 are arranged adjacent to the inclination sensor 5 , and the fourth hydraulic cylinder 230 is hinged to the two mounting seats 231 , respectively.

[0048] Specifically, the electrical control cabinet 25 can control the telescopic distance of the piston rod in the fourth hydraulic cylinder 230 through the solenoid valve group 24 according to the data signal transmitted by the inclination sensor 5 to change the inclination angle of the corresponding flattening mechanism 3 .

[0049] In one embodiment of the present invention, Figure 1 As shown, the smoothing mechanism 3 may include a plurality of smoothing beams of different lengths, and the plurality of smoothing beams may be detachably connected together, and a smoothing plate 30 is fixedly connected below the smoothing beams.

[0050] It can be understood that by setting a plurality of rubbing beams of different lengths and detachably connecting the plurality of rubbing beams together, a corresponding number of rubbing beams can be accurately selected and assembled according to the different widths of the road surface. This flexible configuration not only greatly broadens the scope of application of the device, enabling it to easily cope with various road conditions, but also through the clever use of the rubbing plate 30, it can also efficiently roll cement to ensure the stability of construction quality.

[0051] Furthermore, if Figure 1 As shown, the above-mentioned adjustable angle smoothing device also includes a smoothing drive mechanism 6 including a sixth connecting frame 60, a motor 61, a swing arm 62, a fixed arm 63 and an eccentric wheel (not shown in the figure).

[0054] Specifically, relevant personnel control the operation of the motor 61, and the output shaft of the motor 61 drives the swing arm 62 to move back and forth through the eccentric wheel, and the swing arm 62 drives the smoothing mechanism 3 to slide back and forth in a direction perpendicular to the forward direction of the paver through the fixed arm 63.
