Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering, in particular to a leveling machine for concrete surface treatment. Background Art

[0002] With the progress of society and the improvement of people's living standards, the construction of infrastructure is becoming more and more perfect, and people live in more and more buildings, so the demand for concrete is also increasing. In the concrete pouring construction of flat prefabricated parts such as concrete formwork, concrete floor tiles, and cover plates, the surface of the concrete needs to be leveled immediately after pouring. At this time, a special concrete surface leveling device is needed to level the surface of the poured concrete.

[0003] At present, the concrete surface leveling machines on the market are often used directly for flat surfaces. If the precast parts after casting are a certain distance from the ground, such as the concrete cover plate or large floor tiles after casting, it is difficult for the leveling machine to level such precast parts. Often, manual leveling with a scraper or square tube is required, which results in high labor intensity for the workers, slow construction speed, low work efficiency, and difficulty in meeting construction needs.

[0004] The utility model aims to provide a leveling machine for concrete surface treatment, which has the advantage of being able to level concrete prefabricated parts at a certain distance from the ground, and solves the problem that the current concrete leveling machine is inconvenient to adjust the leveling height and has poor practicality.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a leveling machine for concrete surface treatment, comprising a mobile cart, the surface of which is provided with a leveling mechanism and a driving mechanism;

[0006] The leveling mechanism includes a movable frame, a top plate is fixed on the surface of the movable frame, an electric push rod is fixed on the top of the top plate, one end of the electric push rod passes through the top plate and is fixed with a movable plate, a spring is fixed at the bottom of the movable plate, a connecting plate is fixed at the bottom of the spring, a vibration motor is fixed on the top of the connecting plate, a sliding plate slides through the surface of the connecting plate, a scraper is fixed at the bottom of the sliding plate, two U-shaped frames are fixed on the surface of the connecting plate, a flattening roller is rotatably connected to the bottom of the U-shaped frame, two guide rails are fixed on the surface of the mobile cart, a slider is fixed on the surface of the guide rail, and the top of the slider is fixedly connected to the surface of the movable frame.

[0007] As a preferred leveling machine for concrete surface treatment of the utility model, the driving mechanism includes a mounting plate, and the number of the mounting plates is four and they are all fixed to the surface of the mobile cart, the surface of the mounting plate is rotatably connected to a rotating shaft, and two transmission wheels are fixed to the surface of the rotating shaft, and transmission belts are installed on the surfaces of the transmission wheels on the left and right sides, and a driving motor is fixed to the surface of the mounting plate on one side, and the output shaft of the driving motor is fixedly connected to one end of the rotating shaft on one side, and the surface of the transmission belt is fixedly connected to the bottom of the mounting plate.

[0008] As a preferred concrete surface treatment leveling machine of the utility model, push plates are fixed on both left and right sides of the scraper surface, and the push plates are arranged in a wedge-shaped structure.

[0009] As a preferred concrete surface treatment leveling machine of the utility model, a collecting groove is provided on the surface of the scraper.

[0010] As a preferred concrete surface treatment leveling machine of the utility model, a combined plate is fixed on the surface of the connecting plate, a fixed knob is threadedly penetrated on the surface of the combined plate, and a through hole used to cooperate with the fixed knob is opened on the surface of the sliding plate.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] The utility model can achieve an automatic leveling effect on the top surface of the concrete precast part by setting a leveling mechanism. First, the mobile cart is pushed to the top of the concrete precast part to be leveled. Specifically, the size of the movable wheels at the bottom of the mobile cart can be changed to adapt to the use requirements of concrete precast parts of different thicknesses. After the mobile cart is moved to the top of the concrete precast part, the electric push rod is adjusted to move the moving plate downward so that the scraper can contact the surface of the concrete precast part. Then, the vibration motor and the driving mechanism are started to make the scraper move. At this time, the flattening roller will first apply pressure to the surface of the wet concrete precast part. With the vibration generated by the vibration motor, the flattening roller can accelerate the discharge of water inside the concrete, so that the aggregate in the concrete is arranged more closely, thereby Improve the initial density and final strength of concrete. After being pressed by the flattening roller, the subsequently moving scraper can more accurately adjust the flatness and levelness of the concrete surface, ensuring that the final concrete surface reaches an extremely high flatness standard. After the dual treatment of the flattening roller and the scraper, the concrete surface tends to be perfect, and the subsequent workload of grinding, repairing, etc. is greatly reduced, reducing the total construction time and cost. Compared with traditional manual leveling, this device reduces the need for workers to directly contact wet concrete, reduces labor intensity and potential safety risks, and can also adapt to concrete precast parts of different thicknesses. The slider can slide on the guide rail surface to ensure the stability of the movable frame, and the spring can produce compression deformation to improve the vibration effect of the connecting plate.

[0025] First, push the mobile cart 1 to the top of the concrete precast part to be leveled. Specifically, the size of the movable wheels at the bottom of the mobile cart 1 can be changed to adapt to the use requirements of concrete precast parts of different thicknesses. After the mobile cart 1 is moved to the top of the concrete precast part, adjust the electric push rod 203 to move the movable plate 204 downward so that the scraper 209 can contact the surface of the concrete precast part, and then start the vibration motor 207 and the drive mechanism 3 to move the scraper 209. At this time, the flattening roller 211 will first apply pressure to the surface of the wet concrete precast part, and with the vibration generated by the vibration motor 207, the flattening roller 211 can accelerate the discharge of moisture inside the concrete, so that the aggregates in the concrete are arranged more closely, thereby improving the initial density and final strength of the concrete. After being pressed by the flattening roller 211, the subsequently moving scraper 209 can more accurately adjust the flatness and levelness of the concrete surface, ensuring that the final concrete surface reaches an extremely high flatness standard. After the dual treatment of the flattening roller 211 and the scraper 209, the concrete surface tends to be perfect, and the subsequent workload of grinding, repairing, etc. is greatly reduced, reducing the total construction time and cost. Compared with traditional manual leveling, this device reduces the need for workers to directly contact wet concrete, reduces labor intensity and potential safety risks, and can also adapt to concrete precast parts of different thicknesses. The slider 217 can slide on the surface of the guide rail 216 to ensure the stability of the movable frame 201, and the spring 205 can produce compression deformation to improve the vibration effect of the connecting plate 206.

[0026] Further, the driving mechanism 3 includes a mounting plate 301, the number of the mounting plates 301 is four and they are all fixed to the surface of the mobile cart 1, the surface of the mounting plate 301 is rotatably connected with a rotating shaft 302, the surface of the rotating shaft 302 is fixed with two transmission wheels 303, the surfaces of the transmission wheels 303 on the left and right sides are installed with transmission belts 304, a driving motor 305 is fixed to the surface of one side of the mounting plate 301, the output shaft of the driving motor 305 is fixedly connected to one end of the rotating shaft 302 on one side, and the surface of the transmission belt 304 is fixedly connected to the bottom of the mounting plate 301;

[0027] When the driving motor 305 is started, the two transmission wheels 303 on the surface of the rotating shaft 302 on one side will rotate, and the transmission belt 304 will drive the transmission wheel 303 on the surface of the rotating shaft 302 on the other side to rotate. When the transmission belt 304 is moving, the movable frame 201 can move with the transmission belt 304, thereby achieving the effect of changing the position of the scraper 209, thereby completing the leveling of the surface of the concrete precast part.

[0028] Furthermore, push plates 212 are fixed on both sides of the scraper 209, and the push plates 212 are wedge-shaped.

[0029] The wedge-shaped design of the push plate 212 helps to more accurately control the distribution of concrete, especially when dealing with edges and corners, and can more effectively scrape and push the concrete onto the scraper 209 to ensure the uniformity and flatness of the concrete surface.

[0030] Furthermore, a collection groove 213 is provided on the surface of the scraper 209;

[0031] The concrete scraped off by the push plate 212 can be accumulated on the surface of the scraper 209 and then fall into the collecting tank 213, thereby realizing the collection and processing of the excess concrete material.

[0032] Furthermore, a combination plate 214 is fixed on the surface of the connection plate 206, a fixing knob 215 is threadedly penetrated on the surface of the combination plate 214, and a through hole is opened on the surface of the sliding plate 208 for use with the fixing knob 215;

[0033] After the fixing knob 215 is twisted into the combination plate 214, the fixing knob 215 can enter the through hole to complete the fixing of the sliding plate 208, so that the scraper 209 can be removed from the connecting plate 206, thereby facilitating the replacement and maintenance of the scraper 209.

[0034] Further, the transmission wheel 303 is a timing pulley, and the transmission belt 304 is a timing belt;

[0035] The combination of the timing pulley and the timing belt can increase the friction between the transmission belt 304 and the transmission wheel 303, thereby ensuring that the movable frames 201 on both sides can move normally and synchronously.

[0036] Furthermore, two guide rods 218 are passed through the surface of the top plate 202, and the bottom of the guide rods 218 is fixedly connected to the top of the movable plate 204;

[0037] When the movable plate 204 moves, the guide rod 218 can slide on the surface of the top plate 202, so that the movable plate 204 can obtain a guiding effect, thereby improving the stability of the movable plate 204 when moving.

[0038] Furthermore, a controller 4 is fixed on the surface of the mobile cart 1, and the controller 4 is electrically connected to the electric push rod 203, the vibration motor 207 and the drive motor 305;
