[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] Reference Figure 1 、 Figure 2 and Figure 3 The utility model provides an embodiment of a pavement construction device for municipal road engineering, including a workbench 1. The four corners of the top wall of the workbench 1 are fixedly connected to support columns 3, which can support the top plate 4. The tops of multiple support columns 3 are fixedly connected to the top plate 4, and the middle part of the top of the top plate 4 is fixedly connected to a hydraulic oil tank 5. The hydraulic oil tank 5 can store hydraulic oil to provide power for a rammer 7. The left and right sides of the hydraulic oil tank 5 are connected with oil pipes 6. The middle parts of the two oil pipes 6 pass through the bottom ends of the left and right sides of the top plate 4. The bottom ends of the two oil pipes 6 are connected with rammers 7. The rammers 7 can compact the road surface. The bottom ends of the two rammers 7 are fixedly connected to a rammer base 8, and the middle parts of the top walls of the two rammers 7 are fixedly connected to a telescopic rod. 9. The top ends of the two telescopic rods 9 are fixedly connected to the left and right sides of the bottom wall of the top plate 4 respectively. The telescopic rods 9 can ensure that the rammer 7 can move up and down stably. Movable grooves 10 are provided on the left and right sides of the top wall of the workbench 1. The outer walls of the two rammers 7 and the movable grooves 10 are slidably connected to the inner walls of the two movable grooves 10 respectively, which can ensure the linear movement of the rammer 7. The top ends of the adjacent two rammers 7 are fixedly connected with a connecting rod 11. The middle part of the bottom wall of the connecting rod 11 is fixedly connected with a spring 12. The bottom end of the spring 12 is fixedly connected to the middle part of the inner wall of the workbench 1. The spring 12 can achieve double hammering in one drop to improve the compaction efficiency. The left and right sides of the workbench 1 are provided with a moving wheel height adjustment mechanism 2. The moving wheel height adjustment mechanism 2 can adjust the height of the device to adapt to different terrains.

[0040] Specifically, the hydraulic oil tank 5 provides power to the rammer 7 through the oil pipes 6 on the left and right sides. When the hydraulic oil enters the rammer 7 through the oil pipe 6, the rammer 7 begins to fall under the action of the hydraulic pressure. Since the top of the rammer 7 is fixedly connected to the telescopic rod 9, and the top of the telescopic rod 9 is fixedly connected to the left and right sides of the bottom wall of the top plate 4, the rammer 7 can move up and down stably within a certain range. Movable grooves 10 are provided on the left and right sides of the top wall of the workbench 1. The rammer 7 and the outer wall of the movable groove 10 are slidably connected to the inner wall of the movable groove 10. This can ensure that the rammer 7 maintains linear motion during the falling and rising process. A connecting rod 11 is fixedly connected to the top of the two adjacent rammers 7. A spring 12 is fixedly connected to the middle part of the bottom wall of the connecting rod 11, and the bottom end of the spring 12 is fixedly connected to the middle part of the inner wall of the workbench 1. When the rammer 7 falls, the rammer base 8 first contacts the road surface for the first hammering. As the rammer 7 continues to fall, the spring 12 on the connecting rod 11 is compressed. When the rammer 7 rises, the spring 12 releases elastic potential energy, driving the connecting rod 11 and the rammer 7 to fall again and perform a second hammering, forming a double hammering in one fall, which improves the compaction efficiency. The power provided by the hydraulic system makes the rammer 7 have a greater compaction strength, thereby improving the compaction efficiency of the road surface. The support column 3 and the top plate 4 provide a stable support structure for the entire device.

[0041] Reference Figure 1 and Figure 4 The left movable wheel height adjustment mechanism 2 includes a supporting angle iron 201, which is fixed to the left side of the workbench 1 by a plurality of fixing bolts 202, which can play a role of stable support. The right ends of the plurality of fixing bolts 202 pass through the left inner side of the workbench 1 to strengthen the firmness of the connection. The front and rear sides of the top wall of the supporting angle iron 201 are fixedly connected with an adjusting column 203, which can provide support and guidance. The inner walls of the two adjusting columns 203 are threaded with an adjusting screw rod 204, which can adjust the height of the universal wheel 205. The bottom ends of the two adjusting screw rods 204 are rotatably connected to the universal wheel 205, which facilitates the movement of the device. A plurality of adjusting holes 206 are equidistantly provided on the left side of the two adjusting screw rods 204 and the adjusting column 203. The adjusting hole 206 can be used to accurately adjust the height. The left sides of the two adjusting columns 203 are penetrated and threaded with an adjusting bolt 207, which can fix the adjusted height.

[0042] Specifically, the left and right sides of the workbench 1 are provided with a moving wheel height adjustment mechanism 2. Taking the left moving wheel height adjustment mechanism 2 as an example, the supporting angle iron 201 is fixed to the left side of the workbench 1 by multiple fixing bolts 202. The inner wall of the adjusting column 203 fixedly connected to the front and rear sides of the top wall of the supporting angle iron 201 is threadedly connected to the adjusting screw rod 204. The bottom end of the adjusting screw rod 204 is rotatably connected to the universal wheel 205. By rotating the adjusting screw rod 204, the height position of the universal wheel 205 can be changed. When it is necessary to accurately adjust the height, the adjusting column 203 and the adjusting screw rod 204 can be used to fix the multiple adjusting holes 206 and adjusting bolts 207 equidistantly opened on the left side of the adjusting column 203 and the adjusting screw rod 204. The adjusting bolts 207 are passed through the adjusting holes 206 at the appropriate position and tightened, so as to achieve precise adjustment of the height of the universal wheel 205. The right moving wheel height adjustment mechanism 2 is the same as the left side. It can flexibly adjust the height and level of the workbench 1 according to the needs of the actual construction site, facilitate the construction device to perform road construction operations under different terrain conditions, and improve the adaptability and stability of the construction device.

[0043] Reference Figure 1 、 Figure 2 and Figure 5 , a pressure gauge 13 is fixedly connected to the front side of the hydraulic oil tank 5, and the pressure gauge 13 is electrically connected to the hydraulic oil tank 5. The pressure gauge 13 can display the pressure value in the hydraulic oil tank 5 in real time so that construction personnel can understand the working status of the hydraulic system. The top ends of multiple adjusting screws 204 are fixedly connected to knobs 14. The knobs 14 facilitate construction personnel to rotate the adjusting screws 204 to adjust the height of the universal wheels 205. The outer walls of multiple knobs 14 are fixedly connected with anti-skid particles 15. The anti-skid particles 15 can increase the friction of the outer wall of the knob 14 to prevent slipping during operation. A towing hook 16 is fixedly connected to the top end of the front side of the workbench 1. The towing hook 16 can be used to connect external traction equipment to facilitate the movement and transportation of the device. The left and right sides of the towing hook 16 are fixedly connected with towing rings 17. The towing ring 17 can increase the stability and reliability of the connection;

[0044] Specifically, the pressure gauge 13 is electrically connected to the hydraulic oil tank 5 and can display the hydraulic pressure value in the hydraulic oil tank 5 in real time. The working status of the hydraulic system can be intuitively understood through the pressure gauge 13 so as to adjust the hydraulic pressure in time. The knob 14 is fixed to the top of the adjusting screw 204, which is convenient for construction personnel to rotate the adjusting screw 204 to adjust the height of the universal wheel 205. The anti-slip particles 15 increase the friction force of the outer wall of the knob 14, making it easier for construction personnel to exert force when operating the knob 14. The tow hook 16 and the tow ring 17 can be easily connected to external traction equipment, so that the construction device can be easily dragged to different construction sites. When the construction device needs to be transferred, the tow hook 16 and the tow ring 17 provide a reliable connection point, which improves the maneuverability of the construction device.

[0045] Reference Figure 1 、 Figure 2and Figure 5 , a horizontal frame 18 is fixedly connected to the front side of the top wall of the workbench 1, and a spirit level 19 can be installed and fixed on the horizontal frame 18. A plurality of spirit levels 19 are fixedly connected to the inner wall of the horizontal frame 18. The spirit level 19 can help construction workers judge whether the workbench 1 is in a horizontal state to ensure the quality of construction. The outer walls of the plurality of universal wheels 205 are provided with anti-slip grooves 20. The anti-slip grooves 20 can increase the friction between the universal wheels 205 and the ground and improve the stability of the device. The plurality of anti-slip grooves 20 are arranged in an eight-shaped cross-arrangement. This arrangement can further enhance the anti-slip effect. A pressure hole 21 is provided on the adjacent side of the plurality of knobs 14. The pressure hole 21 can be connected to an external pressure device when needed to facilitate adjustment of the adjustment screw 204. The plurality of pressure holes 21 respectively pass through the inner walls of the plurality of knobs 14;

[0046] Specifically, the multiple spirit levels 19 on the horizontal frame 18 can help construction workers determine whether the workbench 1 is in a horizontal state. During the road construction process, it can ensure that the rammer 7 falls vertically, thereby improving the quality and uniformity of compaction. The anti-slip grooves 20 arranged in an eight-shaped cross shape increase the friction between the universal wheel 205 and the ground, thereby improving the stability of the construction device during movement and preventing the construction device from sliding due to wet or uneven ground during construction. The pressure hole 21 can be connected to an external pressure device when needed to provide additional pressure for the adjustment of the adjusting screw 204, thereby completing the adjustment operation conveniently and quickly.

[0047] Working principle: The hydraulic oil tank 5 provides power to the rammer 7 through the oil pipes 6 on the left and right sides. When the hydraulic oil enters the rammer 7 through the oil pipe 6, the rammer 7 begins to fall under the action of the hydraulic pressure. Since the top of the rammer 7 is fixedly connected with the telescopic rod 9, and the top of the telescopic rod 9 is fixedly connected to the left and right sides of the bottom wall of the top plate 4, the rammer 7 can move up and down stably within a certain range. The left and right sides of the top wall of the workbench 1 are provided with movable grooves 10. The outer wall of the rammer 7 and the movable groove 10 are slidably connected to the inner wall of the movable groove 10, which can ensure that the rammer 7 is falling and During the rising process, the two rammers 7 maintain linear motion. The top ends of the two adjacent rammers 7 are fixedly connected with a connecting rod 11. The middle part of the bottom wall of the connecting rod 11 is fixedly connected with a spring 12. The bottom end of the spring 12 is fixedly connected to the middle part of the inner wall of the workbench 1. When the rammer 7 falls, the ramming base 8 first contacts the road surface for the first hammering. As the rammer 7 continues to fall, the spring 12 on the connecting rod 11 is compressed. When the rammer 7 rises, the spring 12 releases its elastic potential energy, driving the connecting rod 11 and the rammer 7 to fall again for the second hammering, forming a double hammering in one fall.

[0048] In addition, the left and right sides of the workbench 1 are provided with a moving wheel height adjustment mechanism 2. Taking the left moving wheel height adjustment mechanism 2 as an example, the supporting angle iron 201 is fixed to the left side of the workbench 1 by multiple fixing bolts 202. The inner wall of the adjusting column 203 fixedly connected to the front and rear sides of the top wall of the supporting angle iron 201 is threadedly connected to the adjusting screw rod 204. The bottom end of the adjusting screw rod 204 is rotatably connected to the universal wheel 205. The height position of the universal wheel 205 can be changed by rotating the adjusting screw rod 204. When the height needs to be precisely adjusted, the adjusting column 203 and the adjusting screw rod 204 can be used to fix them. The adjusting bolt 207 is passed through the adjusting hole 206 at the appropriate position and tightened, thereby achieving precise adjustment of the height of the universal wheel 205. The right moving wheel height adjustment mechanism 2 is the same as the left side, and can flexibly adjust the height and levelness of the workbench 1 according to the needs of the actual construction site.
