Description

Technical Field

[0001] The present invention relates to the technical field of paver equipment application, and in particular to a road surface height difference adjustment device for a paver, a paver and an adjustment method. Background Art

[0002] A paver is a construction equipment mainly used for paving various materials on the base and surface layers of highways. The paving work is completed by the cooperation of various systems, mainly including the travel system, hydraulic system, material distribution system, etc.

[0003] The screed plate of a hydraulically retractable paver usually consists of three independent mechanical structures. During construction, the screed plates at the left and right ends can be freely retracted and retracted by hydraulic drive. During construction of a paver with this type of screed plate, the material paved under the three screed plates will have a height difference (the whole is not a horizontal plane). At this time, the operator needs to adjust the relative height difference of the three screed plates by manually or by controlling the hydraulic drive through an electric control switch to adjust the mechanical structure to eliminate the height difference of the paved material.

[0004] However, this height difference often occurs when the width of the paving road changes or the speed of the paver changes or when paving outside, so the operator needs to make frequent adjustments, which brings relatively high labor intensity to the operator.

[0005] Therefore, it is desired in the art to provide a road surface height difference adjustment device for a paver to solve the above technical problems. Summary of the invention

[0006] The purpose of the present invention is to provide a road surface height difference adjustment device for a paver, which can obtain the angle change data between the sensing plate and the adjustment rod in real time through a controller, so as to compare the height difference between the first ironing plate and the second ironing plate, and then quickly send an action command signal to the step difference adjustment member to adjust the height of the first ironing plate in real time until the height difference between the first ironing plate and the second ironing plate is eliminated.

[0007] According to a first aspect of the present invention, there is provided a road surface height difference adjustment device for a paving machine, comprising a paving body,

[0014] The step adjustment member is configured to adjust the height of the first ironing plate according to a signal sent by the controller, thereby eliminating a height difference between the first ironing plate and the second ironing plate.

[0015] In one embodiment, the step adjustment member includes an adjustment screw connected to the first ironing plate, a drive motor spaced apart from the adjustment screw, and a conveyor belt sleeved outside the adjustment screw and the drive motor.

[0016] In one embodiment, the sensing plate and the adjusting rod form an angle of 20-70°.

[0017] In one embodiment, the fixing member comprises a bracket arranged on a side wall of the ironing body, and an adapter plate arranged below the bracket, wherein the controller is located in the adapter plate.

[0018] In one embodiment, a support portion extending downward in the longitudinal direction is provided on the bracket, and the adapter plate is fixed to the support portion by a U-shaped screw and a butterfly nut.

[0037] The present invention will be further described below in conjunction with the accompanying drawings.

[0038] Figure 1 The structure of a road paving machine according to the invention is shown schematically.

[0039] Figure 2 for Figure 1 A partial view of the present invention shows the positional relationship between the monitoring mechanism 30 and the first ironing mechanism 20.

[0040] like Figures 1-2 As shown, according to the first aspect of the present invention, a road surface height difference adjustment device for a paving machine is provided, which mainly includes a paving body 10 and a first ironing mechanism 20 arranged on one side of the paving body 10. The first ironing mechanism 20 includes an ironing body 21 and a first ironing plate 22 arranged on the ironing body 21. Preferably, during the paving process, the paving material is compacted under the action of the first ironing plate 22 to form a paved road surface.

[0041] Preferably, a second screed plate is provided on the paving body 10, and during the paving process, the paving material is also compacted under the action of the second screed plate to form a paved road surface.

[0042] At present, there are problems affecting the paving quality during the paving process of the paver, namely, there is a height difference (step difference phenomenon) between the paved road surface formed by the first ironing mechanism 20 and the paved road surface formed by the paving body 10, which causes a watershed mark to appear on the paved road surface, seriously affecting the road surface quality. Moreover, this height difference often occurs when the width of the paving road changes, the driving speed of the paver changes, or when paving outside.

[0043] Therefore, in order to solve these problems, the present invention provides a monitoring mechanism 30 and a step adjustment member on the ironing body 21, which will be described and explained in detail below.

[0044] Figure 3 It is a front view of the monitoring mechanism 30. Figure 4 It is a right side view of the monitoring mechanism 30.

[0045] According to the present invention, Figures 2 to 4 As shown, the road surface height difference adjustment device for the paving machine further includes a monitoring mechanism 30. Preferably, the monitoring mechanism 30 includes a fixing member arranged on the ironing body 21, a sensing plate 31 spaced apart from the fixing member, and an adjusting rod 32 arranged between the fixing member and the sensing plate 31. The sensing plate 31 is in direct contact with the paving road surface, and the sensing plate 31 and the first ironing plate 22 are always at the same height, so the actual height of the first ironing plate 22 can be obtained in real time through the sensing plate 31, in other words, the actual height of the paving road surface formed by the first ironing mechanism 20 can be obtained.

[0046] During the paving process, since the working state of the second ironing plate is relatively stable, the actual height of the paved road surface formed by the paving body 10 remains unchanged. Therefore, by obtaining the actual height of the first ironing plate 22, the height difference between the paved road surface formed by the first ironing mechanism 20 and the paved road surface formed by the paving body 10 can be determined.

[0047] In one embodiment of the present invention, a controller is provided in the fixing part, and the adjusting rod 32 is movably connected to the sensing plate 31, that is, when the actual height of the paved road surface formed by the first ironing mechanism 20 changes, the sensing plate 31 will also rise or fall accordingly, thereby changing the angle between the sensing plate 31 and the adjusting rod 32, and the real-time data brought by the angle change will also be recorded by the controller to facilitate the subsequent issuance of appropriate action instructions to the step adjustment member (described below).

[0048] In the present invention, the controller is constructed as a step difference sensor, and the controller can judge the height difference between the paving road surface formed by the paving body 10 and the paving road surface formed by the first ironing mechanism 20 through the angle change data between the sensing plate 31 and the adjusting rod 32, so as to accurately and timely issue action instructions to the step difference adjusting part.

[0049] Preferably, the induction plate 31 and the adjustment rod 32 form an angle of 20 to 70 degrees. Preferably, the initial setting value of the induction plate 31 and the adjustment rod 32 is 45 degrees. Therefore, when the angle formed by the induction plate 31 and the adjustment rod 32 is greater than 45 degrees, the first ironing plate 22 can be adjusted upward to eliminate the height difference between the first ironing plate 22 and the second ironing plate; when the angle formed by the induction plate 31 and the adjustment rod 32 is less than 45 degrees, the first ironing plate 22 can be adjusted downward to eliminate the height difference between the first ironing plate 22 and the second ironing plate.

[0050] In one embodiment, Figures 3-4 As shown, the fixing member includes a bracket 301 disposed on the side wall of the ironing body 21, and an adapter plate 302 disposed below the bracket 301. Preferably, the controller is located in the adapter plate 302, so that the change in the angle between the induction plate 31 and the adjustment rod 32 can be accurately recorded.

[0051] In one embodiment, Figure 3 As shown, a support portion 303 extending downward in the longitudinal direction is provided on the bracket 301. Preferably, the adapter plate 302 is fixed to the support portion 303 by a U-shaped screw 304 and a butterfly nut 305, so as to improve the firmness and stability between the monitoring mechanism 30 and the ironing body 21.

[0052] According to the present invention, the first ironing mechanism 20 further includes a step adjustment member disposed on the ironing body 21. Preferably, the step adjustment member can receive an action instruction from the controller, and can control the first ironing plate 22 according to the action instruction. In other words, the step adjustment member can adjust the height of the first ironing plate 22 in real time according to the signal sent by the controller, thereby eliminating the height difference between the first ironing plate 22 and the second ironing plate.

[0053] In one embodiment, Figure 2 As shown, the step adjustment member includes an adjustment screw 41 connected to the first ironing plate 22, a drive motor 42 arranged at a distance from the adjustment screw 41, and a conveyor belt 43 sleeved outside the adjustment screw 41 and the drive motor 42. Therefore, by rotating the drive motor 42 forward or reversely, the actual height of the first ironing plate 22 can be adjusted through the conveyor belt 43 and the adjustment screw 41, so that the height difference between the first ironing plate 22 and the second ironing plate can be eliminated more easily and quickly.

[0054] According to a second aspect of the present invention, Figure 1 As shown, a paving machine is provided, comprising the road surface height difference adjustment device as described above, and a second ironing mechanism 50 arranged on a side of the paving body 10 away from the first ironing mechanism 20.

[0055] In the present invention, a vehicle-mounted control system is also provided in the paver. The system sets a reference in the initial state, and then obtains the angle change data between the induction plate 31 and the adjustment rod 32 in real time through the controller, so as to compare the height difference between the first ironing plate 22 and the second ironing plate (that is, to compare the height difference between the paving road surface formed by the paving body 10 and the paving road surface formed by the first ironing mechanism 20), and then sends the action command to the step adjustment member after analysis and calculation by the vehicle-mounted control system;

[0056] Furthermore, after receiving the action command from the controller, the step adjustment member can control the first ironing plate 22 according to the action command. In other words, the step adjustment member can adjust the height of the first ironing plate 22 in real time according to the signal sent by the controller, thereby eliminating the height difference between the first ironing plate 22 and the second ironing plate.

[0057] Preferably, the vehicle control system will upload all data to the cloud server through the DataBox data transmission terminal and store it, and the construction site can be monitored and viewed through the mobile phone APP or the command room web terminal.

[0058] According to a third aspect of the present invention, there is provided a method for adjusting the paving machine as described above, comprising the following steps:

[0059] First, the controller records the angle change data between the sensing plate 31 and the adjusting rod 32 in real time, thereby determining the height difference between the paving body 10 and the first ironing mechanism 20, and then sending an action command signal to the step adjustment member.

[0060] Then, the step adjustment member adjusts the height of the first ironing plate 22 in real time according to the signal sent by the controller until the height difference between the first ironing plate 22 and the second ironing plate is eliminated.

[0061] Compared with the prior art, the advantages of the present invention are:

[0062] First, the device obtains the angle change data between the sensing plate 31 and the adjusting rod 32 in real time through the controller, thereby comparing the height difference between the first ironing plate 22 and the second ironing plate, and further comparing the height difference between the paving road surface formed by the paving body 10 and the paving road surface formed by the first ironing mechanism 20, and then can quickly send an action command signal to the step adjustment member to adjust the height of the first ironing plate 22 in real time until the height difference between the first ironing plate 22 and the second ironing plate is eliminated.

[0063] Second, the device realizes fully automatic control and adjustment through the monitoring mechanism 30 and the step adjustment member, thereby solving the error or delay problem caused by manual operation. In addition, this method can not only greatly reduce the labor intensity of manual operation, but also make the control more accurate, so as to obtain more comprehensive data.

[0064] Third, the data of this device can be displayed simultaneously at the construction site and the rear command room, which makes the display more flexible and diverse, reduces the density of on-site construction personnel, and improves the safety of the construction site. In addition, the data can be stored synchronously in the on-site controller and the cloud server, which is convenient for storage and later tracking and tracing.

[0065] The above are only preferred embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art can easily make changes or modifications within the disclosure scope of the present invention, and such changes or modifications should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
