Description

Technical Field

[0001] The utility model belongs to the technical field of asphalt pavement construction machinery and equipment, and in particular relates to a modified paver capable of adjusting the paving angle. Background Art

[0002] Based on the actual situation that hard shoulders are not used for vehicles, the owners of expressways and some national highways have proposed a plan to add overlay to the main lanes while not overlaying the hard shoulders in order to save maintenance costs when designing the pavement maintenance and overlay reinforcement (such as Figure 1 As shown). In order to achieve a smooth connection between the main lane and the hard shoulder, an 80cm wide slope transition section is designed between the two. The existing paver ironing plate cannot be bent in the vertical direction, and cannot pave the required slope transition section with the main line at one time. The initial solution was to weld a triangular steel plate under the original paver ironing plate, but this destroyed the original ironing plate of the paver and caused damage to the paver. Another method is to make a separate extension block and assemble it on the outside of the paver, and achieve paving of the slope transition section by adjusting the vertical angle, but this assembled extension block does not have a vibration compaction and heating device, and the surface of the paved asphalt concrete is rough, and the initial compaction degree does not meet the requirements. The utility model realizes the adjustment of the angle of the ironing plate in the vertical direction, which solves the problem of one-time paving and forming of the slope transition section between the main lane and the hard shoulder and the paving surface quality is completely consistent. Utility Model Content

[0003] In order to solve the problems in the background technology, the utility model provides a modified paver with adjustable paving angle, and the splicing mechanism installed on the paver has all the functions of heating, vibration, compaction, etc. The splicing mechanism is modified by assembling and lengthening blocks of the ironing board of the same model paver. The heating, vibration, and compaction mechanisms of the original assembled blocks are retained during the modification process, and all the functions of heating, vibration, compaction, etc. can be realized after connecting the circuit and oil circuit of the paver.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A splicing mechanism is installed on the left or right side of the paver, and the splicing mechanism includes an assembled ironing plate, a hydraulic motor, and a vibration rammer drive shaft; the side of the paver is hingedly connected to the assembled ironing plate through a rotating hinge, and a vibration rammer drive shaft is installed on the assembled ironing plate, and the vibration rammer drive shaft is connected to the output shaft of the hydraulic motor through a pulley.

[0006] A steel plate is installed on the side of the paver, and a rotating hinge is welded on the bottom of the steel plate.

[0007] The splicing mechanism is connected to the paver through an angle adjustment screw and a rotating hinge; one end of the angle adjustment screw is hingedly connected to the top of the steel plate, and the other end is hingedly connected to a side of the splicing mechanism away from the main ironing plate.

[0008] The angle adjustment screw is adjusted to extend and retract to drive the splicing mechanism to rotate, thereby achieving angle adjustment between the main ironing plate and the assembled ironing plate of the paver. The angle adjustment range is: 0 to 5 degrees.

[0009] A rotating handle is welded on the angle adjusting screw rod to assist in manually rotating the angle adjusting screw rod.

[0010] A hydraulic motor is fixed to the side of the splicing mechanism away from the main ironing plate through a welded mounting plate. The hydraulic motor is provided with hydraulic oil by adding a branch oil circuit to the main oil circuit of the paving machine ironing plate, and the hydraulic oil is transported through a rubber tube.

[0011] The hydraulic motor provides vibration force to the rotating shaft of the vibration rammer drive shaft, thereby realizing the compaction function of the assembled ironing board.

[0012] The assembled screed plate can lay out a broken line segment with an angle of 0 to 5 degrees with the main screed plate and a width of about 80 cm. It is suitable for paving the main lane with an additional 4 to 6 cm, while the hard shoulder is not paved, and paving the slope transition section between the two.

[0013] The beneficial effects of the utility model are:

[0014] The utility model is designed with a splicing mechanism modified by assembling and lengthening blocks of the screed plate of the same type of paver, which realizes the adjustment of the folding angle of the screed plate in the vertical direction, and solves the problem of paving and forming the slope transition section between the main lane and the hard shoulder in one time. The heating, vibration, and compaction mechanisms of the original assembly blocks are retained during the modification process. After connecting the circuit and oil circuit of the paver, all functions such as heating, vibration, and compaction can be realized, achieving the effect of making the paving surface of the slope transition section completely consistent with the main lane, and will not cause structural and functional damage to the screed plate assembly blocks. When the folding angle is adjusted to 0 degrees, it can be used as an extension block of the screed plate to pave a plane consistent with the main screed plate; when the folding angle is adjusted downward, a slope transition section with a certain angle to the main lane can be paved.

[0017] In the figure: paver 1, assembled ironing board 2, hydraulic motor 3, vibratory rammer drive shaft 4, pulley 5, angle adjustment screw 6, lower connecting plate 7, rotating hinge 8, upper connecting plate 9 DETAILED DESCRIPTION

[0018] The utility model is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 2 As shown, the utility model device is modified by using two pieces of Vögele paver assembly blocks. The assembly blocks can be installed on the left and right sides of the paver, and the assembly mechanisms on both sides cannot be replaced. The utility model adds an upper connecting plate 9 and a lower connecting plate 7 to the assembly surface where the original paver assembly block connects with the ironing plate, and uses this steel plate to connect with the main ironing plate of the paver. The upper connecting plate 9 and the assembled ironing plate 2 are connected by an angle adjustment screw 6 to achieve the paving angle adjustment of the assembled ironing plate. The bottom end of the lower connecting plate is welded by a rotating hinge, and the bottom of the assembled ironing plate 2 close to the main ironing plate is connected to the rotating hinge.

[0020] The assembly ironing board 2 is equipped with a hydraulic motor 3, and the hydraulic oil is transported from the main machine to the hydraulic motor 3 through a rubber tube. The hydraulic motor provides vibration force for the rotating shaft of the assembly ironing board to achieve compaction. Since the assembly block has corresponding heating, vibration, and compaction devices, it only needs to process the connecting oil pipe to connect the hydraulic oil circuit and turn on the heating circuit to work normally.

[0021] Before the modification, the vibration and compaction power source of the original assembly block of the paver was the connecting main shaft of the main ironing plate, and the power was connected through the connecting gear. In order to adjust the paving angle, the method of connecting the main shaft power through the gear was not feasible, so a steel plate was welded on the right end of the assembly mechanism, a hydraulic motor was installed on this steel plate, a branch pipe quick connector was added to the main ironing plate, and the oil pipe was processed to connect the hydraulic motor output power, and then the vibration and compaction shaft was driven to rotate through the pulley. Specific embodiment:

[0023] The assembled screed plate 2 has all the functions of the main screed plate of the paver, such as heating, vibration, and compaction. It can also adjust the slope angle of the transition section up and down. When it is adjusted to the highest point (at this time, the main screed plate and the assembled screed plate 2 are on the same horizontal plane), it is equivalent to adding a section of screed assembly blocks to pave a paving surface that is exactly the same as the main lane, thereby improving the paving quality of the slope connection section and meeting the slope connection requirements of the transition section of the hard shoulder without a mask.

[0024] The main screed plate is used for paving the main lane, and the assembled screed plate 2 is used for paving the transition section between the main lane and the hard shoulder. The transition section between the main lane and the hard shoulder is paved using the assembled screed plate 2 with a certain inclination angle, so that the main lane and the hard shoulder can be smoothly connected after paving, which is convenient for driving and avoids the problem of height difference between the main lane and the hard shoulder after paving.
