Description

Technical Field

[0001] The utility model relates to the technical field of road maintenance equipment, and particularly relates to a concrete road maintenance device. Background Technique

[0002] Concrete needs to be cured because after it is freshly poured and before it is fully hardened and reaches the design strength, it is in a continuous hydration reaction and hardening process. The main purpose of curing is to ensure that the concrete can obtain sufficient strength and durability during this critical early stage, and to avoid cracks and other quality problems.

[0003] Covering and sprinkling wet curing is a common and effective concrete curing method. Wet gunny bags, plastic films or special covering materials can be used to cover the concrete surface. These coverings help prevent premature evaporation of moisture and keep the concrete surface wet. This method requires sprinkling water first, then laying the film, and then sprinkling water again, and multiple processes are required to complete it, wasting a lot of time, cost and manpower. At the same time, during the laying of the film, the film needs to be cut according to the length of the road, increasing the construction burden. Therefore, we designed a concrete road maintenance device. Content of the Utility Model

[0004] The utility model purpose of the present utility model is to provide a concrete road maintenance device, which can be automatically laid as the device moves, and can perform the sprinkling process both before and after laying, and can cut the film after laying, solving the problems raised in the background technique.

[0005] To achieve the above purpose, the present utility model is realized through the following technical solutions: A concrete road maintenance device includes a main body frame. On the upper surface of the main body frame, limiting plates are fixedly connected to both the left and right sides. Limiting grooves are opened on the sides of the limiting plates. A film roller is placed between the two limiting grooves. A limiting component is also arranged in the limiting plates. On the lower surface of the main body frame, brackets are fixedly connected to both the left and right sides. A flattening roller is movably connected between the brackets. A shearing mechanism is arranged between the brackets and above the flattening roller;

[0006] The shearing mechanism includes:

[0007] An installation groove, which is opened on the side of the bracket;

[0008] A fixing plate, which is fixedly connected between the two installation grooves;

[0009] A movable plate, which is movably connected between the two installation grooves;

[0010] A strip-shaped groove, which is opened in the fixing plate;

[0011] An electric slide rail, which is fixedly installed in a strip-shaped groove;

[0012] A cutting knife, which is fixedly connected to a slider inside the electric slide rail;

[0013] Nozzles are fixedly communicated with both the front and rear sides of the lower surface of the main body frame. A water pump is fixedly installed on the side surface of the main body frame and is communicated with the main body frame. A moving component is also arranged on the bracket corresponding to the position of the flattening roller.

[0014] Through the above technical solution, in this application, the film covering roller is placed between the limiting grooves in the two limiting plates, and then the film on the film covering roller is pulled out and passed through between the fixed plate and the movable plate, and finally passes under the flattening roller and is limited by the flattening roller. The film covering roller will roll under the friction force between the film and the road surface and the gravity of the film. Then, as the whole device moves, the film will be automatically laid. When initially laying, since the laying length of the film is short, construction workers can step on it to limit it. Then, the nozzles designed in the front and rear sprinkle water both before and after laying to ensure the maintenance effect. The main body frame is of a hollow design, so that it serves as both the overall support bracket and the water pipe to allow water to flow through. The water inlet end of the water pump is communicated with an external water source, and the water outlet end sprays through the nozzle and the main body frame. After the film laying is completed, start the electric slide rail to drive the cutting knife to move and cut the film, which saves a lot of time, cost and manpower.

[0015] Preferably, a threaded rod is movably connected between the fixed plate and the movable plate, and the threaded rod is located in the installation groove. A driving motor is fixedly installed on the side surface of the fixed plate, and the output end of the driving motor penetrates through the fixed plate and is fixedly connected to the threaded rod.

[0016] Through the above technical solution, after the film laying is completed in this application, start the driving motor to drive the movable plate to approach the fixed plate. At this time, the movable plate will pull the film to make it taut and close to the cutting knife to ensure the cutting effect of the movement of the cutting knife.

[0017] Preferably, the limiting component includes: a through hole, an electric telescopic rod and a push plate. A through hole is opened on the limiting plate and is communicated with the limiting groove. The electric telescopic rod is fixedly installed in the through hole, and the output end of the electric telescopic rod is fixedly connected to the push plate.

[0018] Through the above technical solution, after the film laying is completed in this application, start the electric telescopic rod to drive the push plate to move to limit the film covering roller. At this time, the film covering roller is difficult to rotate, and the whole device will not move either. The film is in a taut state. Cooperating with the threaded rod and the driving motor, the cutting effect is further enhanced to ensure complete cutting.

[0019] Preferably, the moving component includes: a strip-shaped hole, a sliding block, and an electric push rod. The strip-shaped hole is formed in the bracket. The sliding block is slidably connected in the strip-shaped hole. Both ends of the flattening roller extend into the corresponding sliding blocks and are movably connected to the sliding blocks. The inner top wall of the strip-shaped hole is fixedly installed with an electric push rod, and the output end of the electric push rod is fixedly connected to the top of the sliding block.

[0020] Through the above technical solution, when the electric push rod is started in this application to drive the sliding block to move, that is, the flattening roller can move up and down to adapt to the laying of different materials of the film, and at the same time, it can also prevent the flattening roller from contacting the sand and gravel on the road surface when not in use, which will cause an impact.

[0021] Preferably, a cutting groove is formed on one side of the movable plate close to the fixed plate, and the cutting knife extends into the cutting groove.

[0022] Through the above technical solution, the movable plate in this application gradually approaches the fixed plate as the threaded rod rotates. At this time, the cutting knife will gradually insert into the cutting groove, giving the cutting knife enough cutting space, making the cutting knife move and cut more quickly and completely, and ensuring the cutting effect.

[0023] Preferably, the inner wall of the limiting groove is movably connected with a plurality of balls, and the balls are in contact with the film covering roller.

[0024] Through the above technical solution, the balls in this application enable the film covering roller to rotate normally in the limiting groove without affecting the limiting effect of the film covering roller.

[0025] By adopting the foregoing technical solutions, the beneficial effects of the present utility model are as follows:

[0026] 1. For this concrete road maintenance device, place the film covering roller in the limiting plate, then pass the film in the film covering roller through the space between the fixed plate and the limiting plate and roll along the flattening roller, and then it can automatically cover the film as the whole device moves, reducing the pressure on construction workers. And it can sprinkle water before and after laying to ensure the maintenance effect. After laying, the film can be sheared by the shearing mechanism to complete the laying process, saving a lot of time, manpower and cost, and solving the problems raised in the background technology.

[0027] 2. For this concrete road maintenance device, through the design of the limiting component, the film covering roller can be limited, so that the film is in a taut state during shearing, ensuring the completeness of shearing. Through the design of the moving component, the flattening roller can move up and down. On the one hand, it can be adjusted to cooperate with different materials of the film. On the other hand, it can prevent the flattening roller from contacting the road surface sand and gravel when not in use, which will cause an impact. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] A cutting knife 86 is fixedly connected to the slider in the electric slide rail 85;

[0042] Nozzles 9 are fixedly communicated with both the front and rear sides of the lower surface of the main body frame 1. A water pump 10 is fixedly installed on the side surface of the main body frame 1 and is communicated with the main body frame 1. A moving assembly 14 is further provided at the position of the flattening roller 7 on the bracket 6.

[0043] Through the above technical solutions, in this application, the film covering roller 4 is placed between the limiting grooves 3 in the two limiting plates 2, and then the film on the film covering roller 4 is pulled out through between the fixed plate 82 and the movable plate 83, and finally passes under the flattening roller 7 and is limited by the flattening roller 7. The film covering roller 4 will roll due to the friction between the film and the road surface and the gravity of the film. Then, as the whole device moves, the film will be automatically laid. When initially laying, since the laying length of the film is short, construction workers can step on it to limit it. Then, the nozzles 9 designed in the front and back sprinkle water both before and after laying to ensure the maintenance effect. The main body frame 1 is of a hollow design, so that it not only serves as the overall support bracket 6 but also serves as a water pipe to allow water to flow through. The water inlet end of the water pump 10 is communicated with an external water source, and the water outlet end sprays through the nozzle 9 with the main body frame 1. When the film laying is completed, start the electric slide rail 85 to drive the cutting knife 86 to move to cut the film, which saves a lot of time, cost and manpower.

[0045] Through the above technical solutions, after the film laying is completed in this application, start the driving motor 12 to drive the movable plate 83 to approach the fixed plate 82. At this time, the movable plate 83 will pull the film to make it taut and close to the cutting knife 86 to ensure the cutting effect of the movement of the cutting knife 86.

[0046] The limiting assembly 5 includes: a through hole 51, an electric telescopic rod 52 and a push plate 53.

An electric telescopic rod 52 is fixedly installed in the through hole 51, and the output end of the electric telescopic rod 52 is fixedly connected to the push plate 53.

[0047] Through the above technical solution, after the film covering is laid, the electric telescopic rod 52 is activated to drive the push plate 53 to move and limit the film covering roller 4. At this time, it is difficult for the film covering roller 4 to rotate, and the whole device will not move either. The film covering is in a tight state. Then, in cooperation with the threaded rod 11 and the driving motor 12, the cutting effect is further enhanced to ensure complete cutting.

[0048] The moving component 14 includes: a strip-shaped hole 141, a sliding block 142, and an electric push rod 143. A strip-shaped hole 141 is formed in the bracket 6. A sliding block 142 is slidably connected in the strip-shaped hole 141. Both ends of the flattening roller 7 extend into the corresponding sliding blocks 142 and are movably connected to the sliding blocks 142. The inner top wall of the strip-shaped hole 141 is fixedly provided with an electric push rod 143, and the output end of the electric push rod 143 is fixedly connected to the top of the sliding block 142.

[0049] Through the above technical solution, the present application activates the electric push rod 143 to drive the sliding block 142 to move, that is, the flattening roller 7 can move up and down to adapt to the laying of film coverings of different materials. At the same time, it can also prevent the flattening roller 7 from contacting the sand and gravel on the road surface when not in use, which may cause an impact.

[0050] A cutting groove 13 is formed on one side of the movable plate 83 close to the fixed plate 82, and the cutting knife 86 extends into the cutting groove 13.

[0051] Through the above technical solution, the movable plate 83 of the present application gradually approaches the fixed plate 82 following the rotation of the threaded rod 11. At this time, the cutting knife 86 will gradually insert into the cutting groove 13, giving the cutting knife 13 sufficient cutting space, making the cutting knife 86 move and cut more quickly and completely, and ensuring the cutting effect.

[0052] The inner wall of the limiting groove 3 is movably connected with a plurality of balls 15, and the balls 15 are in contact with the film covering roller 4.

[0053] Through the above technical solution, the balls 15 of the present application enable the film covering roller 4 to rotate normally in the limiting groove 3 without affecting the limiting effect on the film covering roller 4.

[0054] When the concrete road maintenance device is working, the film covering roller 4 is placed between the limiting grooves 3 in the two limiting plates 2. The electric push rod 143 is started to drive the sliding block 142 to move, that is, the flattening roller 7 can move up and down to adjust the distance from the road surface, so as to adapt to the material covered on the film covering roller 4 for laying. Then, the film covered on the film covering roller 4 is pulled out through the space between the fixed plate 82 and the movable plate 83, and finally passes under the flattening roller 7 and is limited by the flattening roller 7. The film covering roller 4 will roll due to the friction between the film and the road surface and the gravity of the film, that is, as the whole device moves, the film will be automatically laid. The water pump 10 is started to spray water on the road surface before and after laying through the main body frame 1 and the front and rear nozzles 9, so as to ensure the maintenance effect. After laying is completed, the electric telescopic rod 52 is started to drive the push plate 53 to move to limit the film covering roller 4. At this time, the film is in a taut state. Then, the driving motor 12 is started to drive the movable plate 83 to approach the fixed plate 82. The movable plate 83 will pull the film to make it taut and close to the cutting knife 86. The cutting knife 86 is inserted into the cutting groove 13 and moves along with the slider in the electric slide rail 85 to cut the film, so as to ensure the completeness of cutting.
