Description

Technical Field

[0001] This utility model relates to the field of road maintenance technology, and more specifically, to a concrete road maintenance device. Background Technology

[0002] In traditional slipform construction of road shoulders, water trucks are used to spray water on the soil shoulder to moisten it. However, the water evaporates quickly, causing the soil shoulder to absorb the water in the slipform concrete. This leads to a decrease in the moisture content of the road shoulder concrete, resulting in insufficient moisture for the concrete to set and harden, which causes cracking. Therefore, to prevent cracking, it is necessary to keep the soil shoulder adequately moist to provide moisture for the concrete to set and harden, thus preventing cracking.

[0003] Existing technologies, such as a utility model of a road surface concrete curing device (authorization announcement number CN220116979U), utilize a curing membrane laid on the watered concrete surface during the watering process. This membrane acts as a water-locking agent, effectively reducing moisture evaporation and achieving a good curing effect.

[0004] Currently, there is a lack of a device that facilitates spraying water first, then covering with film, using pressure rollers to roll the film so that it adheres tightly to the road surface, and keeping the pressure rollers away from the ground when not in operation to facilitate device relocation. Utility Model Content

By using the rotation of the screw and connecting rod, the position adjustment of the pressure roller is easily realized, facilitating transfer and film rolling.

[0010] As a further limitation of this technical solution, the axle of one of the wheels and the central axis of the pressure roller are respectively fixedly connected to the central axis of the synchronous pulley. The central axes of the two synchronous pulleys are respectively bearing-connected to one end of the protective plate. The other ends of the two protective plates are respectively rotatably connected to the axle of the double rotating wheel.

[0011] As a further limitation of this technical solution, the guide circular pipe threaded connection bolt and the movable shaft are provided with positioning holes, and the bolt matches the positioning holes. By using bolts and positioning holes, the movable shaft can be easily fixed.

[0012] As a further limitation of this technical solution, the maintenance vehicle is fixedly connected to a handle to facilitate the movement of the pushing device.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Example 1: A concrete road maintenance device includes: a maintenance vehicle 2, equipped with a film installation slot, wherein the maintenance vehicle 2 is fixedly connected to a guide tube 17 corresponding to the film installation slot, and the axles of two sets of symmetrical wheels 3 are connected to the maintenance vehicle 2 by bearings; a fixed end shaft 9, connected to the maintenance vehicle 2 by bearings; a movable end shaft 19, connected to a movable shaft 18 by bearings, the movable shaft 18 being disposed within the guide tube 17; a water tank 4, fixedly connected to the maintenance vehicle 2, and a water pump 8 fixedly connected to the water tank 2; and a water pipe 5, fixedly connected to the water tank 4 by symmetrical crossbars, the water pipe 5 being fixedly connected to a set of evenly distributed nozzles 6, one end of the water pipe 5 being fixedly connected to a flexible hose 7, and the other end of the flexible hose 7 being fixedly connected to the water pump 8. By setting the nozzles 6, water is sprayed onto the road surface. The use of the movable shaft 18 facilitates the installation of the plastic film cylinder, facilitating subsequent film laying and enabling convenient road maintenance.

[0026] The guide tube 17 is threadedly connected to the bolt 16, and the movable shaft 18 is provided with a positioning hole 20, with the bolt 16 matching the positioning hole 20. By using the bolt 16 and the positioning hole 20, the movable shaft 18 can be easily fixed.

[0027] The maintenance vehicle 2 is fixedly connected to the handle 1, which facilitates the movement of the pushing device.

[0028] The working principle of the concrete road maintenance device provided by this utility model is as follows:

[0029] When installing the plastic film tube, unscrew the bolt 16, move the movable shaft 18 completely into the guide tube 17, insert one end of the plastic film tube into the fixed end shaft 9, move the movable end shaft 19 to the other end of the plastic film tube, and tighten the bolt 16 to make it enter the positioning hole 20.

[0030] Push the device forward and control the water pump 8 to work, so that the nozzle 6 sprays clean water. When the membrane moves to the water spray area, pull the end of the membrane to make it contact the ground. Workers step on the membrane to realize the membrane laying.

[0031] The maintenance vehicle 2 is fixedly connected to a U-frame 10, which in turn is fixedly connected to symmetrical guide tubes 11. Vertical rods 12 are respectively installed inside the symmetrical guide tubes 11, and each of the symmetrical vertical rods 12 is connected to the central axis of a pressure roller 13 via bearings. By using the pressure roller 13, which contacts the film, film laying is facilitated.

[0032] Example 2: The symmetrical guide tubes 11 are respectively fixedly connected to the corresponding vertical rods 12.

[0033] The working principle of the concrete road maintenance device provided by this utility model is as follows:

[0034] Push the device forward and control the water pump 8 to work, so that the nozzle 6 sprays clean water. When the film moves into the water spray area, pull the end of the film so that it passes around the pressure roller 13 and contacts the ground, push the device to continue moving, and the pressure roller 13 rolls the film to achieve film laying.

[0035] Example 3: The axle of one wheel 3 and the central shaft of the pressure roller 13 are respectively fixedly connected to the central shaft of the synchronous pulley 21. The central shafts of the two synchronous pulleys 21 are respectively bearing-connected to one end of the protective plate 24. The other ends of the two protective plates 24 are respectively rotatably connected to the axle of the double rotating wheel 23. One end of each of the two synchronous belts 22 wraps around one of the rotating wheels of the double rotating wheel 23, and the other end of each of the two synchronous belts 22 wraps around the corresponding synchronous pulley 21. By using synchronous belt drive and the bearing connection between the double rotating wheel 23 and the synchronous pulley 21 and the protective plate 24, transmission is easily achieved.

[0036] The working principle of the concrete road maintenance device provided by this utility model is as follows:

[0037] The device is propelled forward, and the water pump 8 is controlled to operate, causing the nozzle 6 to spray clean water. When the film moves into the water spray area, the end of the film is pulled so that it passes under the pressure roller 13 and contacts the ground. The screw 15 is rotated, which drives the moving ring 25 and the upper cross block 26 to move. The upper cross block 26 drives the connecting rod 27 to swing. The connecting rod 27 drives the lower cross block 26, the vertical rod 12, and the pressure roller 13 to move downward. The vertical rod 12 moves along the guide tube 11, causing the pressure roller 13 to press the film tightly. The pressure roller 13 drives the lower synchronous wheel 21 to move downward. The lower synchronous wheel 21 drives the lower protective plate 24, the lower synchronous belt 22, and the double rotating wheel 23 to swing. The double rotating wheel 23 drives the upper protective plate 24 and the upper synchronous belt 22 to swing. As the device continues to move, the wheel 3 rotates, which in turn drives the upper synchronous wheel 21 to rotate. The upper synchronous wheel 21 drives the upper synchronous belt 22 to move. The upper synchronous belt 22 drives the double rotating wheel 23 to rotate. The double rotating wheel 23 drives the lower synchronous belt 22 to move. The lower synchronous belt 22 drives the lower synchronous wheel 21 and the pressure roller 13 to rotate. The pressure roller 13 rolls the film, thus achieving film laying.
