[0003] For example, the Chinese patent with publication number CN217054203U discloses a concrete leveling device for construction engineering. In view of the problem that the existing leveling device will absorb impurities and particles on the surface when in contact with the ground, and cannot be cleaned in time, which will affect the leveling effect, the following scheme is proposed, which includes a connecting base plate, two adjustment seats, two leveling rollers, two cleaning components and two support plates. The two adjustment seats are fixedly installed at the bottom of the connecting base plate, and the bottoms of the two adjustment seats are provided with fixed grooves. The leveling rollers are rotatably installed in the corresponding fixed grooves. The cleaning components are arranged on the corresponding adjustment seats, and the leveling rollers corresponding to the cleaning components are connected. The two support plates are fixedly installed on the top of the connecting base plate. The leveling device of the utility model will absorb impurities and particles on the surface when in contact with the ground, and can be cleaned in time without affecting the leveling effect.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used, such as: the leveling roller and the cleaning brush roller will be worn after long-term use, the device is not convenient for replacing the leveling roller and the cleaning brush roller, and when the area of ​​some flat surfaces is large, it is not convenient for the staff to put the device in the middle of the flat surface for leveling, which is inconvenient to use. In view of this, we propose a concrete leveling device for construction engineering. Utility Model Content

[0006] The utility model aims to provide a construction engineering concrete leveling device to solve the problems raised in the above-mentioned background technology.

[0007] In view of this, the utility model provides a construction engineering concrete leveling device, comprising:

[0008] Material toggling mechanism, its both sides respectively have the support of the support frame, and the support frame has the support frame of being made up of the groove of the sliding door, and the support frame has the support frame of being made up of the groove of the sliding door, and the support frame has the support frame of being made up of the groove of the sliding door.

[0009] A connecting block, wherein the connecting block is fixedly mounted on the top of the rectangular plate, and a rotating rod is rotatably mounted in the connecting block, rubber rings are fixedly mounted on both sides of the rotating rod and located in the connecting block, a rectangular groove is opened in the rotating rod, and a pull rod is slidably mounted in the rectangular groove;

[0010] A driving assembly is located in the rotating rod and is used to drive the pull rod to slide in the rectangular groove.

[0011] In the present technical scheme, when the cleaning roller and the leveling roller are worn out after long-term use and need to be replaced, the staff manually rotates the handle on one of the two-way threaded rods in the opposite direction to drive one of the two-way threaded rods to rotate, and then, under the action of the thread, the two-way threaded rod will drive two of the sliding plates away from each other, and then, the two sliding plates will drive the corresponding two transmission wheels away from each other, and then, the limit groove on the transmission wheel will slowly move away from the limit block until the limit groove is completely moved out of the limit block, and the circular groove will also move out of the limit block, at this time, one of the cleaning rollers and one of the leveling rollers will be released, and then, they can be disassembled and replaced, and when installing a new cleaning roller and a new leveling roller, the staff first places the new cleaning roller and the new leveling roller between two of the sliding plates, and The new cleaning roller is located on the top of the new leveling roller. Then, the staff member manually turns the handle on one of the two-way threaded rods in the forward direction and causes one of the two-way threaded rods to rotate. Then, under the action of the thread, the two-way threaded rod will drive two of the sliding plates to approach each other. Then, the two sliding plates will drive the corresponding two transmission wheels to approach each other until the two limit blocks on the new cleaning roller and the two limit blocks on the new leveling roller enter the corresponding circular grooves. Then, the two sliding plates continue to approach each other until the two limit blocks on the new cleaning roller and the two limit blocks on the new leveling roller are inserted into the corresponding limit grooves. Then, the new cleaning roller and the new leveling roller will be fixed between the two sliding plates. Through the above operations, the staff can disassemble and replace the other cleaning roller and the other leveling roller.

[0012] Subsequently, when the work is being carried out, when the area of ​​some of the ground is large and the middle position of the ground needs to be leveled, the driving assembly is set to drive the pull rod to move upward in the rectangular groove until the pull rod can no longer move. Subsequently, the staff holds the top of the pull rod and drives the rotating rod to rotate in the connecting block. Under the action of the rubber ring, there is a large friction between the rubber ring and the connecting block, so that the rotating rod will not rotate too fast, ensuring the structural stability of the connecting block and the rotating rod. Subsequently, the staff can stand at the edge of the ground and push the pull rod back and forth. At this time, the two leveling rollers will rotate, and then the two limit blocks on the leveling roller will rotate. The two limit blocks respectively drive the two transmission wheels on both sides of the leveling roller to rotate, and then the two transmission wheels on both sides of the leveling roller will drive the corresponding belt drive, and then the two belts will drive the two transmission wheels on both sides of the cleaning roller to rotate, and then the two transmission wheels on both sides of the cleaning roller will drive the two limit blocks on the cleaning roller to rotate, and then the cleaning roller will rotate and clean the impurities on the leveling roller, and under the action of the scraper, the impurities on the leveling roller can be scraped off.

The top end of the worm wheel passes through the top of the power cavity, extends into the rectangular groove and is coaxially connected to the threaded rod. One end of the worm passes through one side of the rectangular groove and extends to the outside.

[0015] In this technical solution, the staff can turn the handle on the worm and make it drive the worm to rotate. Under the action of meshing, the worm will drive the worm wheel to rotate, and then the worm wheel will drive the threaded rod to rotate. Under the action of the thread, the threaded rod will drive the pull rod to move upward until the pull rod can no longer move further, ensuring that the pull rod can be displaced in the rectangular groove.

[0016] In the above technical solution, further, the upper end of the worm wheel is rotatably connected to the rectangular groove, and the length of the threaded rod is the same as the height of the rectangular groove.
