Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

Referring to fig. 1 and 2, an embodiment of the present application provides a road surface maintenance device 10 for road traffic engineering construction. The pavement maintenance device 10 for highway traffic engineering construction comprises a vehicle body 100, a heating plate 110, a driving device 120 and a control device. The heating plate 110 is movably disposed at the bottom of the vehicle body 100. That is, the heating plate 110 can move in the horizontal direction and the vertical direction at the bottom of the vehicle body 100. The driving unit 120 is provided in the vehicle body 100 and is connected to the heating plate 110 via a driving shaft 122. The driving means 120 is used for controlling the heating plate 110 to move in the vertical direction and the horizontal direction at the bottom of the vehicle body 100. The driving device 120 may be a motor, or may be a combination of multiple motors, and drives the heating plate 110 to move in the horizontal direction or the vertical direction at the bottom of the vehicle body 100. The control means is connected to the driving means 120 and the heating plate 110. The control device can be a processor such as a PLC. The control device may be provided to the vehicle body 100. The surface of the heating plate 110 near the ground is provided with a pressure sensor 124. The pressure sensor 124 is connected to the control device. That is, a pressure signal sensed by the pressure sensor 124 may be transmitted to the control device.

The driving device 120 is used for controlling the heating plate 110 to approach and contact the ground to be repaired through the driving shaft 122. When it is determined that the floor surface to be repaired is ready, the control device may send a command to the driving device 120, and the driving device 120 drives the driving shaft 122 so that the heating plate 110 approaches the floor surface to be repaired. When the pressure signal measured by the pressure sensor 124 reaches a first preset value, it indicates that the heating plate 110 has contacted the ground. The control means controls the heating plate 110 to be heated. As the heating plate 110 becomes warmer and warmer, the temperature of the ground becomes warmer and warmer, and the asphalt will gradually soften and melt. When the pressure signal measured by the pressure sensor 124 reaches a second preset value, it indicates that the asphalt has melted and softened to a certain extent. That is, the second preset value becomes smaller than the first preset value. Indicating that the asphalt pavement to be repaired has reached a level at which it can be removed. At this time, the control device controls the heating plate 110 to rise through the driving device 120, and stops heating. Therefore, the steps of cutting and shoveling the asphalt pavement can be carried out, and the efficiency of maintaining the pavement is greatly improved.

It is understood that the driving means may include a plurality of driving motors, and the driving motors may move the driving shaft 122 up or down.

Referring to fig. 3, in one embodiment, a plurality of cutting blades 130 are further disposed at intervals on the surface of the heating plate 110 close to the ground. The control device is connected with the driving motor for controlling the cutting knife 130. The driving motor may drive the cutting knife 130 to move in a vertical direction. When the heating plate 110 rises to a preset height, the control device controls the cutting knife 130 to rotate and cut the ground to be repaired close to the ground to be repaired. Because the ground has softened, the cutting blade 130 is now close to the ground and rotated to cut the asphalt pavement to be repaired. While the cutting knife 130 rotates, the driving device 120 may also control the heating plate 110 to rotate, so as to achieve sufficient cutting and crushing of the asphalt pavement. It will be appreciated that each of the cutting knives may correspond to a motor. The synchronous operation of a plurality of motors can drive the cutting knife to rotate simultaneously.

After cutting, the crushed asphalt can be removed by a shovel or a scraper.

Referring to fig. 3, in one embodiment, the road surface maintenance device 10 for road traffic engineering construction further includes a guide rail plate 200. The rail plate 200 is disposed at the bottom of the vehicle body 100. The guide plate 200 is provided with cross guides 210. The driving shaft 122 is disposed on the cross rail 210, and the control device controls the heating plate 110 to move in the horizontal direction of the cross rail 210 through the driving device 120. Thereby enabling the heating pan 110 to be moved over any position of the ground to be repaired. After the heating pan 110 is moved above the ground to be repaired, the control means controls the heating pan 110 to descend by the driving shaft 122. The driving means 120 may comprise a servo motor. The heating plate 110 can be controlled by a servo motor to move in the horizontal direction of the cross guide 210. The cross guide rail can also be provided with a sliding block. The slider can be driven to move on the cross rail 210 by a motor. The heating plate 110 may be provided to the slider.

In one embodiment, the road maintenance device 10 for road traffic engineering construction further includes an asphalt nozzle 220. The pitch nozzle 220 is disposed on the surface of the heating plate 110 near the ground. After the asphalt pavement is crushed and cleaned, the asphalt nozzle 220 can spray asphalt to the pavement to be repaired, and the heating plate 110 can be controlled to be pressed down, so that the new asphalt pavement is finished.

In one embodiment, the vehicle body 100 is provided with an asphalt storage tank 300, and the asphalt nozzle 220 is connected to the asphalt storage tank 300 through a flexible pipe 113.

Referring to fig. 4, in one embodiment, after the heating plate 110 is raised to a predetermined position, the cutting knife 130 retracts the heating plate 110. The pitch nozzle 220 can be controlled by a motor to protrude from the surface of the heating plate 110. At this time, the control device may control the asphalt spraying nozzle 220 to spray asphalt to the road surface to be repaired by controlling the compression pump. The vehicle body 100 can keep a static state in the whole repairing process, the repairing position is more accurately positioned, and the local repairing effect of the road surface is better.

Referring to fig. 5, it can be understood that the heating plate 110 can be provided with a circular hole 111. The pitch nozzle 220 extends from the heater plate. The circular hole and the outer wall of pitch nozzle 220 may be connected by bearing 112. That is, when the heating plate 110 rotates, the pitch nozzle 220 may not rotate along with the heating plate 110 and may be kept in a relatively stationary state, and thus, a problem that the pitch nozzle 220 is easily twisted due to the rotation of the heating plate 110 can be avoided. The rail plate 200 may be provided with a through hole, and the flexible pipe 113 may be connected to the asphalt storage tank 300 through the through hole.
