[0003] The ironing plate of the hydraulic telescopic paving machine is usually composed of three independent mechanical structures, and the ironing plates distributed at the left and right ends can be freely telescoped through hydraulic drive during construction. When the paving machine of this form of ironing plate is in construction, the material paved out below the three ironing plates will have a height difference (not a whole level), at which time the operator needs to adjust the relative height difference of the three ironing plates by manually or through the electric control switch to adjust the mechanical structure to eliminate the height difference of the paved material.

[0023] Compared with the prior art, the advantages of the present invention are:
[0024] First, the present invention uses a controller to record the actual difference between the first and second monitoring elements, and then compares the actual difference with the initial difference to determine whether there is a height difference, or step, between the paved surface formed by the first screed and the paved surface formed by the second screed.

[0037] Figure 1 The structure of the paving pavement section difference adjusting device according to the utility model is schematically shown;
[0038] Figure 2 The structure of the first monitoring member is schematically shown.
[0039] As Figure 1 As shown in the first aspect of the utility model, a paving pavement section difference adjusting device is provided, mainly comprising a smoothing main body 110, and a first telescopic main body 120 arranged at the side end of the smoothing main body 110. Preferably, a first smoothing plate 121 is arranged on the first telescopic main body 120, and the first smoothing plate 121 is in contact with the paving pavement, for compacting the pavement. Therefore, during paving, the paving material will be compacted under the action of the first smoothing plate 121 to form the paving pavement.
[0040] In one embodiment, a second smoothing plate 111 in contact with the paving pavement is arranged on the smoothing main body 110, and during paving, the paving material will also be compacted under the action of the second smoothing plate 111 to form the paving pavement.
[0041] At present, there is a problem of affecting the paving quality during the paving process of the paver, that is, the paving pavement formed by the first telescopic main body 120 and the paving pavement formed by the smoothing main body 110 will have a height difference (section difference phenomenon), which will cause the water divide mark on the paved pavement to seriously affect the pavement quality, and this height difference will often occur when the width of the paved road changes or the driving speed of the paver changes or the paver turns to pave.
[0042] Therefore, the utility model discloses in order to solve these problems and set up monitoring mechanism and the adjustment mechanism of adaptation, below carries out the specific description and explanation.
[0043] In the utility model, the working state of the ironing main body 110 and the second ironing plate 111 is relatively stable during paving operation, so the actual height of the paving road surface formed by the ironing main body 110 is always unchanged, so the height difference between the paving road surface formed by the first telescopic main body 120 and the paving road surface formed by the ironing main body 110 can be judged by obtaining the actual data about the first ironing plate 121, which is introduced below.
[0044] According to the utility model, as Figure 1 The monitoring mechanism comprises a first monitoring piece 131, a second monitoring piece 132 and a controller. Preferably, the first monitoring piece 131 is arranged on the ironing main body 110 and is used for monitoring the actual height between the paving road surface formed by the second ironing plate 111 and the first monitoring piece 131; the second monitoring piece 132 is arranged on the first telescopic main body 120 and is used for monitoring the actual height between the paving road surface formed by the first ironing plate 121 and the second monitoring piece 132.
[0045] Preferably, the controller is connected with the first monitoring piece 131 and the second monitoring piece 132 respectively and can receive the recorded data from the first monitoring piece 131 and the second monitoring piece 132, thereby providing important technical support for subsequent judgment of whether the step difference phenomenon exists and whether the adjustment mechanism is driven to work.
[0046] Preferably, before the paving operation is performed, the initial difference measured by the first monitoring piece 131 and the second monitoring piece 132 is inputted in the controller. During the paving process, the paving road surface formed by the first ironing plate 121 and the paving road surface formed by the second ironing plate 111 will appear height difference due to the existence of the step difference phenomenon. At this time, the actual difference between the first monitoring piece 131 and the second monitoring piece 132 is changed compared with the initial difference, and if the change is not corrected within a period of time, the adjustment mechanism can be controlled to eliminate the step difference phenomenon.
[0047] It is worth noting that the change of the difference between the first monitoring piece 131 and the second monitoring piece 132 is usually caused by the height difference (i.e. the step difference phenomenon) between the paving road surface formed by the first ironing plate 121 and the paving road surface formed by the second ironing plate 111.
[0048] Preferably, when the first monitoring member 131 and the second monitoring member 132 are at the initial difference value, the paving road surface formed by the first screed 121 and the paving road surface formed by the second screed 111 do not have a height difference, that is, the height of the first screed 121 and the height of the second screed 111 are completely consistent.
[0049] In an embodiment of the present application, the first monitoring member 131 and the second monitoring member 132 are both configured as ultrasonic sensors. In this way, the height between the paving road surface and the monitoring member (i.e. the first monitoring member 131 or the second monitoring member 132) can be quickly and accurately measured, and according to whether the actual difference value of the first monitoring member 131 and the second monitoring member 132 has changed compared with the initial difference value, it can be judged whether the paving road surface formed by the first screed 121 and the paving road surface formed by the second screed 111 have a step phenomenon.
[0050] In an embodiment, as shown in Figure 2 , the first monitoring member 131 and the second monitoring member 132 are both configured in a U-shaped structure, and both include a main body 133 configured in a plate form. Preferably, at least five first distance measurement probes 134 are provided on the lower end surface of the main body 133 in the transverse direction. Therefore, the actual height difference between the paving road surface formed by the first screed 121 and the paving road surface formed by the second screed 111 can be accurately measured by the first distance measurement probe 134.
[0051] In an embodiment, as shown in Figure 2 , the first monitoring member 131 and the second monitoring member 132 both include a first mounting plate 135 and a second mounting plate 136 provided on both sides of the main body 133. Preferably, a second distance measurement probe 137 is provided on the first mounting plate 135.
[0052] In the present application, the second distance measurement probe 137 emits an ultrasonic signal, which returns to the original route after encountering the second mounting plate 136 to obtain the time required for the entire transmission process. Since the distance between the first mounting plate 135 and the second mounting plate 136 is a fixed value, the ultrasonic flight speed under actual working conditions can be calculated in this way.
[0053] It is worth noting that since the ultrasonic signal is affected by environmental factors such as temperature and wind, the ultrasonic flight speed obtained by the above method is the most accurate value under the current scenario.
[0054] In the utility model, the ultrasonic wave signals emitted by the first distance measuring probe 134 all contact the paving ground and return along the original path, so that the five distance values are obtained according to the ultrasonic wave flight speed obtained above. Preferably, the five values are first removed two values with larger deviations, and the remaining three relatively similar data are summed and averaged to further obtain the actual distance of the ultrasonic sensor from the paving surface, thereby helping to improve the accuracy of the operation of the device to eliminate the step difference phenomenon to the greatest extent.
[0055] In one embodiment, as shown in Figure 1 The paving surface step difference adjusting device comprises a supporting mechanism for fixing the first monitoring member 131 and the second monitoring member 132. Preferably, the supporting mechanism comprises a support rod 141 arranged in the transverse direction, two fixed rods 142 arranged on the support rod 141 in the longitudinal direction, and an adjusting frame matched with the fixed rods 142.
[0056] In the utility model, as shown in Figure 1 The fixed rods 142 are fixedly connected with the support rod 141. There are two adjusting frames, i.e. adjusting frame 144 and adjusting frame 145. Preferably, the adjusting frame 144 is fixedly installed on the smoothing main body 110, and the adjusting frame 145 is fixedly installed on the first telescopic main body 120. In addition, the fixed rods 142 are movably connected with the two adjusting frames, i.e. the height of the first monitoring member 131 or the second monitoring member 132 can be adjusted.
[0057] In one embodiment, as shown in Figure 1 A fixing seat is arranged at the top end of the first monitoring member 131 and the second monitoring member 132. Preferably, the first monitoring member 131 and the second monitoring member 132 are fixedly installed on the support rod 141 through the fixing seat, so as to improve the stability and firmness of the supporting mechanism.
[0058] In one embodiment, as shown in Figure 1 The adjusting mechanism is installed on the smoothing main body 110 and comprises an adjusting screw 151 connected with the first smoothing plate 121, a driving motor 152 arranged in the longitudinal direction and spaced apart from the adjusting screw 151, and a conveyor belt 153 sleeved outside the adjusting screw 151 and the driving motor 152. Therefore, by forward rotation or reverse rotation of the driving motor 152, the actual height of the first smoothing plate 121 can be adjusted through the conveyor belt 153 and the adjusting screw 151, so that the height difference between the first smoothing plate 121 and the second smoothing plate 111 can be more easily eliminated.
[0059] According to the second aspect of the utility model, a paving machine is provided, which comprises the paving surface step difference adjusting device according to the above and a second telescopic main body arranged on the side of the smoothing main body 110 away from the first telescopic main body 120.
[0060] In the utility model, vehicle-mounted control system is further arranged in the paver, the system sets a reference in initial state (namely, the initial difference measured by the first monitoring member 131 and the second monitoring member 132 is recorded by the controller), then the actual difference of the first monitoring member 131 and the second monitoring member 132 is obtained by the controller in real time, so that the actual difference and the initial difference are compared to judge whether the segment difference phenomenon appears between the paving road surface formed by the first screed 121 and the paving road surface formed by the second screed 111, if the segment difference phenomenon appears, the action command is sent to the adjusting mechanism after analysis and operation by the vehicle-mounted control system.
[0061] Furthermore, the adjusting mechanism can control the first screed 121 according to the action command after receiving the action command from the controller, in other words, the adjusting mechanism can adjust the height of the first screed 121 in real time according to the signal from the controller, so that the height difference between the first screed 121 and the second screed 111 is eliminated.
[0062] Preferably, the vehicle-mounted control system uploads all data to the cloud server through the DataBox data remote terminal and stores the data, and the construction site can be monitored and viewed through the mobile phone APP or the web terminal of the command room.
[0063] According to the third aspect of the utility model, a kind of adjusting method is provided, which utilizes the paver according to the above, including the following steps:
[0064] First, the initial difference of the first monitoring member 131 and the second monitoring member 132 is recorded by the controller, and then the actual difference of the first monitoring member 131 and the second monitoring member 132 is recorded by the controller in real time, so that the height difference of the paving road surface formed by the first screed 121 and the second screed 111 is judged to send the indicating signal to the adjusting mechanism.
[0065] Then, the adjusting mechanism adjusts the height of the first screed 121 by driving motor 152 and adjusting screw 151, until the height difference between the first screed 121 and the second screed 111 is eliminated.
[0066] Compared with prior art, the utility model has the advantages that:
[0067] First, the actual difference between the first monitoring member 131 and the second monitoring member 132 can be recorded by the controller, so that the change of the actual difference compared with the initial difference is compared to determine whether there is a height difference, i.e. a step phenomenon, between the paving surface formed by the first leveling plate 121 and the paving surface formed by the second leveling plate 111. In addition, if there is a step phenomenon, the motor 152 and the adjusting screw 151 can be driven to adjust the height of the first leveling plate 121 until the height difference between the first leveling plate 121 and the second leveling plate 111 is eliminated.
[0068] Second, the monitoring mechanism and the adjusting mechanism realize full automatic control and adjustment, so as to solve the error or delay problem caused by manual operation. In addition, this way not only can greatly reduce the labor intensity, but also can make the control more accurate, so as to obtain more comprehensive data.
[0069] In addition, since the monitoring member in the device is an ultrasonic sensor, the height of the paving surface can be measured quickly and accurately. Since the ultrasonic signal is affected by temperature, wind and other environmental factors, the first distance measuring probe 136 and the second distance measuring probe 137 are used to cooperate to obtain the most accurate value in the current scene.
[0070] Third, the data of the device can be displayed synchronously in the construction site and the rear command room, which is more flexible and diverse, reduces the density of on-site construction personnel, improves the safety of the construction site, and the data can be stored in the on-site controller and the cloud server, which is convenient for storage and later tracking and tracing.
