[0025] A telescopic rod mechanism 6 extending downward is fixedly provided on the square tube sleeve 5. The telescopic rod mechanism 6 includes a fixed sleeve 61 fixedly provided on the square tube sleeve 5 and a sliding rod 62. The sliding rod 62 slidably penetrates through the fixed sleeve 61. The sliding rod 62 has a cylindrical structure. The sliding rod 62 can rotate along the inner wall of the fixed sleeve 61. The bottom end of the sliding rod 62 can penetrate out of the fixed sleeve 61. A second locking member is provided between the sliding rod 62 and the fixed sleeve 61.

[0026] The guiding mechanism 2 is arranged at the bottom end of the telescopic rod mechanism 6. The guiding mechanism 2 is used to remind and guide the paving device 1 to maintain the correct paving direction through guiding markings, so as to prevent deviation. The guiding markings are metal wires with strong toughness. Specifically, the guiding mechanism 2 includes a contact rod 21 extending in the front-back direction. The contact rod 21 is arranged perpendicular to the guiding markings in the horizontal direction. A sliding sleeve 22 is slidably sleeved on the contact rod 21. Two limiting ring plates 23 arranged at intervals in the front-back direction are fixedly sleeved on the sliding sleeve 22. The guiding markings are located between the two limiting ring plates 23. Two mounting plates 24 arranged at intervals in the front-back direction are fixedly sleeved on the contact rod 21. The sliding sleeve 22 is located between the two mounting plates 24. A contact switch 25 is fixedly penetrated through the mounting plate 24. The trigger button of the contact switch 25 is located between the two mounting plates 24. When the limiting ring plate 23 is separated from the mounting plate 24, the contact switch 25 is in an open circuit. When the limiting ring plate 23 is in contact with the mounting plate 24, the contact switch 25 is in a closed circuit. The paving vehicle is provided with a controller and a voice module. The controller is in control connection with the voice module. The contact switch 25 is in communication connection with the controller. The voice module is used to emit a prompt sound to remind the driver that the asphalt concrete paving has deviated, so as to correct it. At the same time, voice broadcast is carried out, so that the driver does not need to continuously observe the position between the guiding mechanism 2 and the guiding markings, avoiding affecting the driver's driving and operation of the paver.

[0027] When the limiting ring plate 23 is separated from the mounting plate 24, the contact switch 25 is in an open circuit. When the front limiting ring plate 23 is in contact with the front mounting plate 24, the contact switch 25 is in a closed circuit. The contact switch 25 issues an instruction to the voice module through the controller to remind the driver that the asphalt concrete paving has deviated backward. When the rear limiting ring plate 23 is in contact with the rear mounting plate 24, the contact switch 25 is in a closed circuit. The contact switch 25 issues an instruction to the voice module through the controller to remind the driver that the asphalt concrete paving has deviated forward, so that the driver can correct it in time to prevent the asphalt concrete paving from continuing to deviate.

[0028] One end of the square rod 4 far from the fixed rod 3 is arranged in a front-back and left-right offset manner in space with respect to the paving device 1, so that the guiding mechanism 2 located at one end of the square rod 4 far from the fixed rod 3 can be offset from the paving device 1, avoiding the influence of the paving device 1 on the guiding mechanism 2 during the working process. The sliding rod 62 has a cylindrical structure. The sliding rod 62 can rotate along the inner wall of the fixed sleeve 61, so that by rotating the sliding rod 62, the angle of the contact rod 21 in the guiding mechanism 2 at the bottom of the sliding rod 62 can be adjusted, so that the contact rod 21 is always perpendicular to the guiding markings in the horizontal direction, facilitating the guiding markings to normally push the limiting ring plate 23 and the sliding sleeve 22.

[0029] By adjusting the position of the square pipe sleeve 5 on the square rod 4, the position of the guiding mechanism 2 in the front-rear direction can be adjusted according to the position of the guiding marking line, so that the sliding sleeve 22 is located in the middle between the two mounting plates 24, and at the same time, the guiding marking line can be located between the two limiting ring plates 23. When the guiding mechanism 2 deflects, the guiding marking line can push the limiting ring plate 23 and the sliding sleeve 22, and touch the sound module through contact with the contact switch 25 to give a warning, so as to prevent the asphalt concrete paving from deflecting continuously.

[0030] By controlling the length of the telescopic rod mechanism 6, the height of the guiding mechanism 2 can be adjusted according to the position of the guiding marking line, so that the guiding marking line can be located between the two limiting ring plates 23. When the guiding mechanism 2 deflects, the guiding marking line can push the limiting ring plate 23 and the sliding sleeve 22, and touch the sound module through contact with the contact switch 25 to give a warning, so as to prevent the asphalt concrete paving from deflecting continuously.

[0031] A following mechanism 7 is provided between the telescopic rod mechanism 6 and the guiding mechanism 2. The guiding mechanism 2 is arranged on the following mechanism 7. The following mechanism 7 can make the guiding mechanism 2 always adhere to the guiding marking line, avoiding that during the road surface paving process, the guiding mechanism 2 is separated from the guiding marking line due to the bump of the paving device 1 or the undulation of the guiding marking line. Specifically, the following mechanism 7 includes a fixed box 71 fixedly arranged at the bottom end of the sliding rod 62. A rotating shaft 72 is rotatably penetrated in the fixed box 71. The front end of the rotating shaft 72 penetrates out of the fixed box 71 and is fixedly provided with an inclined rod 73 arranged obliquely from top to bottom and from right to left. The front end of the contact rod 21 is fixedly arranged at the bottom end of the inclined rod 73. A torsion spring 74 is arranged in the fixed box 71. The torsion spring 74 is sleeved on the rotating shaft 72. The rear end of the torsion spring 74 is fixedly arranged on the fixed box 71. The front end of the torsion spring 74 is fixedly arranged on the outer peripheral surface of the rotating shaft 72. The torsion spring 74 is used to apply a downward force to the inclined rod 73 through the rotating shaft 72, so that the contact rod 21 always fits on the guiding marking line, avoiding that the guiding mechanism 2 is separated from the guiding marking line due to the bump of the paving device 1 or the undulation of the guiding marking line.

[0032] Working principle: When in use, according to the position of the guiding marking line, the sliding sleeve 22 is adjusted to the middle part of the front and back of the contact rod 21, and then the position of the square tube sleeve 5 on the square rod 4 is adjusted to make the guiding marking line located between the two limiting ring plates 23 in the front and back directions and fixed by the first locking member; then the length of the telescopic rod mechanism 6 is controlled to make the guiding marking line located between the two limiting ring plates 23 and fixed by the second locking member; during the process of the paving vehicle driving the paving device 1 to work, the guiding marking line passes through between the two limiting ring plates 23. When the route of the paving device 1 deviates, the guiding marking line squeezes and pushes the limiting ring plate 23 towards one side until the limiting ring plate 23 abuts against the mounting plate 24. At this time, the contact switch 25 is in a conducting state, and the contact switch 25 sends an instruction to the voice module through the controller to remind the driver that the asphalt concrete paving has deviated for correction. After correction, the guiding marking line squeezes and pushes the limiting ring plate 23 in the opposite direction, and the limiting ring plate 23 separates from the mounting plate 24, and continues to guide the paving vehicle and the paving device 1 to move normally.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
