Description

Technical Field

[0001] The present invention relates to the technical field of civil engineering equipment. Specifically, it relates to a ground leveling device for civil engineering. Background Technique

[0002] Civil engineering is the general term for civil engineering and construction engineering. It is an engineering discipline that builds various facilities and places for human life, production, protection, etc. It covers the construction of buildings, structures, and engineering works within facilities and places in various engineering scopes such as above ground, underground, on land, on water, and underwater, including houses, roads, railways, airports, bridges, water conservancy, ports, tunnels, water supply and drainage, protection, etc. When laying cement on the ground, in order to ensure the flatness of the ground, a road leveling machine is needed to complete the leveling work of the ground. The actual use has the advantages of simple operation, stable structure, and high working efficiency.

[0003] However, the existing road leveling machines have the following problems when applied: When actually carrying out the leveling work, the protruding positions on the ground will be leveled by the scraper structure, but the sunken positions on the ground cannot be paved. The sunken positions are far from the operators, and it is difficult for the operators to pave the sunken positions at these locations. Secondly, when carrying out the ground leveling work, the operators need to use a variety of tools to repair the ground. When the tools accidentally break away from the hands of the operators, the tools will fall into the wet concrete. The tools need to be cleaned after being contaminated with concrete, and the sunken positions formed by the tools need to be leveled again, increasing the workload of the operators. Finally, there is no cleaning structure. After the road leveling machine finishes working, its surface will be contaminated with a large amount of dust and wet concrete. Due to the large number of surface structures of the road leveling machine, the concave and convex positions are prone to accumulate dust and wet concrete, making it difficult to clean.

[0004] In response to the problems in the related technologies, no effective solutions have been proposed yet. Summary of the Invention

[0005] (1) Technical Problems to be Solved

[0006] In view of the deficiencies of the prior art, the present invention provides the advantages of being able to transfer the operators to the expected positions without affecting the ground leveling work, avoiding the tools from falling into the wet concrete without affecting the use of the tools, and having a cleaning structure that facilitates self-cleaning work, thereby solving the problems in the above background technique.

[0019] (III) Beneficial effects

[0020] Compared with the prior art, the present invention provides a ground leveling device for civil engineering projects, which has the following

[0021] Beneficial effects:

[0022] (1) In the present invention, through the connecting rods, when actually using the ground leveling equipment for civil engineering projects, the operator selects the expected number of connecting rods. By means of the threaded engagement of multiple sets of blind threaded holes with multiple sets of connecting screws and multiple sets of fixing screws, the operator connects the multiple sets of connecting rods end to end in sequence. After the two sets of connecting rods are connected, one end of each of the two sets of connecting rods is respectively passed through the two sets of guide holes, and then one end of each of the four sets of connecting rods is respectively inserted into the interior of the four sets of mounting pipes. By means of the threaded engagement of eight sets of second threaded through holes with eight sets of fastening bolts, the operator rotates the eight sets of fastening bolts clockwise and counterclockwise by hand. When one end of each of the eight sets of fastening bolts is in close contact with the side wall of one end of the four sets of connecting rods, the connection of the scraper is completed. At this time, by means of the eight sets of rollers, the multiple sets of connecting rods can be moved to the expected position. Then the operator stands on the upper part of the scraper. At this time, when the operator pulls the side wall of the multiple sets of connecting rods by hand, it will drive the scraper to move horizontally. During this process, the scraper can level the uncured concrete. When the scraper moves to the sunken position, the operator standing on the upper part of the scraper can level the sunken position at this location. When the scraper moves, the multiple sets of balls roll respectively inside the multiple sets of ball sockets. Due to the smooth surfaces of the multiple sets of balls, the multiple sets of connecting rods do not interfere with the movement and use of the scraper. For the remaining connecting rods, they can be sleeved clockwise on the multiple sets of fixing screws. Through the provided connecting rods, without affecting the ground leveling work, the operator can be transferred to the expected position, improving the adaptability of the ground leveling equipment for civil engineering projects.

[0023] (2) In the present invention, through the mounting frame plate, before actually using the ground leveling equipment for civil engineering projects, the operator moves a set of I-shaped rods upward by hand. The limiting end of this set of I-shaped rods will compress a set of telescopic springs on the same side. When this set of I-shaped rods is moved to the expected position, the operator can place the tool inside this set of mounting frame plates. After the placement is completed, the operator releases the I-shaped rods, and a set of telescopic springs on the same side will push a set of I-shaped rods on the same side to perform a reset movement. This set of I-shaped rods will press down on the tool, making the tool stably fixed inside this set of mounting frame plates. At this time, this set of mounting frame plates can be rotated clockwise and counterclockwise to adjust the length of the same side of a set of pull ropes wound around the same side of a set of fixed shafts. When the winding length of the same side of a set of pull ropes reaches the expected value, the operator can use this set of tools by hand. Due to the pulling of the same side of a set of pull ropes, this set of tools will not fall into the uncured concrete. The use of the remaining sets of tools can be obtained in the same way by operation. Through the provided mounting frame plates, without affecting the use of the tools, it is avoided that the tools fall into the uncured concrete, bringing a guarantee for the ground leveling work of the ground leveling equipment for civil engineering projects.

[0024] (3) Before actually using the ground leveling equipment for civil engineering projects, the present invention utilizes the threaded engagement between two sets of third threaded through-holes and two sets of threaded caps. The operator rotates the two sets of threaded caps counterclockwise by hand. When the two sets of threaded caps are separated from the two mobile carts, the operator can add clear water into the interiors of the two water storage chambers through the two sets of third threaded through-holes. After the clear water is added, the operator resets the two sets of threaded caps. Then, the operator moves one end of the two water spray pipes to the expected position. At this time, when the operator presses down the two T-shaped rods, it can drive the two plug plates to squeeze the clear water inside the two water storage chambers. The clear water sprayed through the two water spray pipes can wash away the dust and uncured concrete adhered to the surface of the ground leveling equipment for civil engineering projects. After the cleaning work is completed, the two magnet plates can adsorb to the end faces of the two mobile carts, fixing one end of the two water spray pipes and preventing the accidental discharge of the clear water inside the two water storage chambers. Through the provided water spray pipes, a cleaning structure is available, facilitating self-cleaning work and adding a cleaning function to the ground leveling equipment for civil engineering projects.

[0047] In one embodiment, all eight rollers 7 are on the same horizontal plane, preventing the scraping plate 3 from being non-parallel to the ground due to the misalignment of the eight rollers 7.

[0048] Working principle:

[0049] When actually using the ground leveling equipment for civil engineering projects, the operator selects an expected number of connecting rods 2. By using the threaded blind holes 16, connecting screws 17 and fixing screws 37 in multiple groups to cooperate with each other in a threaded manner, the operator connects the multiple groups of connecting rods 2 end to end in sequence. After the multiple groups of connecting rods 2 are divided into two groups and connected, one end of each of the two groups of connecting rods 2 penetrates through the two groups of guide holes 18 respectively. Then, the end parts of one end of the four groups of connecting rods 2 are respectively inserted into the interiors of the four groups of mounting pipes 13. By using the eight second threaded through holes 14 and the eight fastening bolts 15 to cooperate with each other in a threaded manner, the operator rotates the eight fastening bolts 15 clockwise and counterclockwise by hand. When the end parts of one end of the eight fastening bolts 15 are in close contact with the side walls of one end of the four groups of connecting rods 2, the connection work of the scraping plate 3 is completed. At this time, by using the eight rollers 7, the multiple groups of connecting rods 2 can be moved to the expected position. Then the operator stands on the upper part of the scraping plate 3. At this time, when the operator pulls the side walls of the multiple groups of connecting rods 2 by hand, it will drive the scraping plate 3 to perform a transverse movement. During this process, the scraping plate 3 can level the uncured concrete. When the scraping plate 3 moves to the sunken position, the operator located on the upper part of the scraping plate 3 can level the sunken position at this place. When the scraping plate 3 moves, the multiple groups of balls 20 roll respectively inside the multiple groups of ball sockets 19. Since the surfaces of the multiple groups of balls 20 are smooth, the multiple groups of connecting rods 2 do not hinder the movement and use of the scraping plate 3. For the remaining connecting rods 2, they can be sleeved clockwise on the multiple groups of fixing screws 37. By setting the connecting rods 2, without affecting the ground leveling work, the operator can be transferred to the expected position, improving the use adaptability of the ground leveling equipment for civil engineering projects. At the same time, before actually using the ground leveling equipment for civil engineering projects, the operator moves a group of I-shaped rods 25 upward by hand. The limiting end of this group of I-shaped rods 25 will compress a group of telescopic springs 26 on the same side. When this group of I-shaped rods 25 moves to the expected position, the operator can put the tool into the interior of this group of mounting frame plates 4. After placing it, the operator releases the I-shaped rod 25, and a group of telescopic springs 26 on the same side will push a group of I-shaped rods 25 on the same side to perform a reset movement. This group of I-shaped rods 25 will press down the tool, making the tool stably fixed inside this group of mounting frame plates 4. At this time, this group of mounting frame plates 4 can be rotated clockwise and counterclockwise to adjust the length of the same side group of pull ropes 23 wound around the same side group of fixed shafts 22. When the winding length of the same side group of pull ropes 23 reaches the expected value, the operator can use this group of tools by hand. Due to the pulling of the same side group of pull ropes 23, this group of tools will not fall into the uncured concrete. The use of the remaining groups of tools can be obtained in the same operation. By setting the mounting frame plates 4, without affecting the use of the tools, it is avoided that the tools fall into the uncured concrete, bringing a guarantee for the ground leveling work of the ground leveling equipment for civil engineering projects. At the same time, before actually using the ground leveling equipment for civil engineering projects, by using the two third threaded through holes 29 and the two threaded caps 30 to cooperate with each other in a threaded manner, the operator rotates the two threaded caps 30 counterclockwise by hand. When the two threaded caps 30 are separated from the two moving carts 1,The operator can add clean water to the interiors of the two water storage chambers 31 through two sets of third threaded through holes 29. After the clean water is added, the operator resets the two threaded caps 30. Then, the operator moves one end of the two water spray pipes 27 to the desired position. At this time, the operator presses down on the two T-shaped rods 33, which can drive the two plug plates 34 to squeeze the clean water inside the two water storage chambers 31. The clean water sprayed through the two water spray pipes 27 can wash away the dust and uncured concrete adhering to the surface of the ground leveling equipment for civil engineering. After the cleaning work is completed, the two magnet plates 28 can adsorb to the end faces of the two moving carts 1, fixing one end of the two water spray pipes 27 and preventing the accidental discharge of the clean water inside the two water storage chambers 31. By providing the water spray pipes 27, a cleaning structure is available, facilitating self-cleaning work and adding a cleaning function to the ground leveling equipment for civil engineering.
