Description

Technical Field

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

[0002] After the concrete pavement is constructed, it needs to be watered and covered with felt for curing; the order of watering and laying felt varies in different construction sections.

[0003] Sprinkle water before laying felt: After concrete is poured or laid, water should be sprinkled in time to keep the surface moist, and then covered with felt to lock in the moisture. To prevent the moisture from evaporating quickly, covering with felt after sprinkling water can prolong the moisturizing time. The advantages are that the road surface is directly wetted before covering, which reduces moisture loss and promotes the hydration or curing reaction of materials (such as the development of concrete strength). The wet surface makes it easier to fix the felt (such as by pressing the edges with heavy objects) and reduces the risk of it being blown away by the wind.

[0004] Laying felt first and then sprinkling water: This method is suitable for the stage of protecting the stability of the roadbed. After laying the felt as a temporary protective layer, water is sprinkled to reinforce loose soil or prevent rainwater erosion (such as slope protection). Water needs to be evenly permeated through the felt (such as graded crushed stone base maintenance). The advantage is that the felt can disperse the water flow pressure and avoid local erosion. It is suitable for loose or highly permeable bases.

[0005] According to the existing technology announcement number CN221663354U, a road surface maintenance device for highway engineering construction adopts a maintenance method of first laying a felt cloth and then sprinkling water. After the felt cloth is laid, the conveying component drives the pressing component to press the felt cloth firmly onto the road surface, and then the watering component sprays water for maintenance.

[0006] However, in this solution, the roll assembly can only accommodate felt fabric of standard width. It cannot be fully applied to felt fabric of different widths. Wider felt fabric rollers cannot be installed. For roads with excessive width, multiple back-and-forth passes are required to complete the paving and maintenance. Secondly, when the felt fabric is being released, its own weight or sudden stops during the process may prevent the felt fabric roller from stopping in time, resulting in a large amount of excess fabric being released and causing the laid felt fabric to accumulate on the road surface.

[0007] Therefore, in view of the above problems, the present invention proposes a solution. Summary of the Invention

[0008] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a concrete pavement maintenance device for road construction, which can adapt to spraying and tarpaulin laying on pavements of different widths, and can orderly control the tarpaulin feeding process through a top pressing mechanism.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0010] A concrete pavement maintenance device for road construction includes a locomotive and a spraying mechanism, a water tank, a support mechanism, a pressing mechanism, and a felt roller mounted on the locomotive.

A water pump conventionally installed in the water tank supplies water to the spraying mechanism to spray the pavement, and felt is laid on the felt roller to cover the pavement. The pressing mechanism presses down on the felt roller to prevent excessive rotational inertia from causing the felt to be laid out too quickly and resulting in excessive felt redundancy.

[0011] The spraying mechanism includes a pair of first support arms, a pair of symmetrically arranged spray pipes, a first electric actuator, and a control plate. The first support arms are fixedly connected to the front end of the locomotive, the first electric actuator is fixedly fixed to the front end of the locomotive, and the control plate is fixedly connected to the top shaft of the first electric actuator. The control plate is provided with a guide shaft and slidably connected to the support plate at the front end of the locomotive. The control plate is provided with a control shaft. The spray pipes are provided with a rotating shaft and rotatably connected to the first support arms. One set of spray pipes is set at a higher height than the other set of spray pipes. The spray pipes are provided with control arms, and the control arms are provided with through grooves. The control shaft is located in the through grooves. One end of the spray pipe is connected to a water tank through a water pipe. The first electric actuator pushes the control plate, and then the control plate and the control shaft push the spray pipes to rotate around the rotating shaft as the axis, so as to achieve the effect of converging the spray pipes towards the center and dispersing them to both sides, thereby adjusting the spraying range.

[0012] The support mechanism includes a motor, a double-acting lead screw, a support shaft, a fixed plate, and mounting arms. A pair of fixed plates are provided and fixed to the rear end of the locomotive. The two ends of the double-acting lead screw are rotatably connected to the fixed plates via bearings, and the support shaft is fixedly connected to the fixed plates. One end of the double-acting lead screw is equipped with a sprocket. The motor is fixed to the rear end of the locomotive, and the motor shaft end is equipped with a sprocket connected to the sprocket at the end of the double-acting lead screw via a chain. A pair of mounting arms are provided and symmetrically arranged. The mounting arms are slidably connected to the support shaft and threadedly connected to the double-acting lead screw. A first mounting groove is provided on the mounting arm for supporting the roller shaft of the felt fabric roller.

[0013] The pressing mechanism includes a roller shaft and a pair of second support arms; the second support arms are fixed on the mounting arms, and the second support arms are provided with a slidingly connected top shaft. The top shaft has a thread and a nut at its top end; a limiting plate is provided at one end of the top shaft, and a sleeve spring is provided on the top shaft. The spring contacts the second support arm and the limiting plate; the two ends of the roller shaft are rotatably connected to the ends of the top shaft; the roller shaft is formed by the insertion of a first pressure roller and a second pressure roller. The first pressure roller has a connecting shaft, and the second pressure roller has a mounting hole. The connecting shaft is inserted into the mounting hole, and the depth of the mounting hole is greater than the length of the connecting shaft.

[0014] Furthermore, the locomotive tail end is also provided with an auxiliary mechanism, which includes a third support arm, a second electric push rod, and a pressure arm; the third support arm is fixed on the locomotive and is provided with a second mounting groove; the pressure arm is provided with a rotating shaft and rotatably connected to the third support arm, and the pressure arm is located in the second mounting groove; the base of the second electric push rod is hinged to the third support arm, and the top shaft of the second electric push rod is hinged to one end of the pressure arm; one end of the pressure arm is provided with a rotatably connected third pressure roller.

[0015] Furthermore, the locomotive is equipped with a storage battery and electrically connected to a first electric actuator and a second electric actuator to supply power to it, and the locomotive supplies power to the storage battery.

[0016] The advantages of this utility model compared with the prior art are as follows:

[0017] 1) The spraying mechanism can push the control plate through the first electric push rod, so that the control shaft and control arm drive the spray pipe to rotate, so that the spray pipe can rotate to expand the spraying range and rotate to shrink the spraying range towards the center, so as to adapt to the spraying requirements of different road widths.

[0018] 2) The top pressing mechanism can use springs to push the limit plate and the top shaft to press down, so that the roller shaft can adaptively contact the felt roller as the felt roller is unloaded. This avoids the felt roller from being unable to stop abruptly due to its own weight or the sudden stop of the locomotive, which would cause a large amount of redundant felt unloaded and the felt to pile up on the ground. At the same time, the first and second pressure rollers on the roller shaft can change positions as the mounting arm moves to adapt to the top pressing of felt rollers of different widths. The cooperation between the connecting shaft and the mounting hole can ensure the integrity of the roller shaft and the top pressing effect. Attached Figure Description
