Description

Technical Field

[0001] The utility model belongs to the technical field of building civil engineering, and in particular relates to a concrete floor grinding device for building civil engineering. Background Art

[0002] Civil engineering, also known as civil construction engineering, is a general term for civil engineering and construction engineering. It covers the construction of buildings, structures, and engineering objects within the facilities and places within the scope of houses, roads, railways, airports, bridges, water conservancy, ports, tunnels, water supply and drainage, protection and other projects in various categories above ground, underground, on land, on water, and underwater. It includes various technical activities such as survey, design, construction, maintenance, and management in the process of engineering construction, as well as the materials, equipment and items consumed in the construction process. Among them, the paving of concrete pavement is an indispensable part of construction.

[0003] After the current construction of building concrete floors is completed, there will be unevenness. At the same time, some floors need to be paved with floor paint after construction. Therefore, a grinding device is needed to grind the floor to ensure the flatness of the floor. However, when the current grinding device is grinding the floor, the contact between the grinding head and the ground will generate dust and small particles. In order to ensure the improvement of engineering efficiency, the dust treatment must also be considered. For this reason, we propose a concrete floor grinding device for construction and civil engineering. Utility Model Content

[0004] The utility model provides a concrete floor grinding device for building civil engineering to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a concrete floor grinding device for construction and civil engineering, comprising a fixed plate, a first protective plate fixedly connected to the lower surface of the fixed plate, a plurality of second protective plates slidably connected inside the first protective plate, the interior of the second protective plate is fixedly connected to the lower surface of the fixed plate through a spring, and a first bearing and a second bearing are fixedly connected to the lower surface of the fixed plate;

[0006] The first bearing and the second bearing are each provided with a first rotating shaft and a second rotating shaft, the surfaces of the first rotating shaft and the second rotating shaft are respectively provided with a first transmission wheel and a second transmission wheel, the first transmission wheel and the second transmission wheel are connected via a transmission belt, the surfaces of the first rotating shaft and the second rotating shaft are respectively installed with a grinding head and a fan blade, and the lower surface of the second protective plate is fixedly connected with a moving wheel and a brush.

[0007] As a further solution of the utility model: the top end of the first rotating shaft is fixedly connected to the surface of the motor output shaft, and the motor body is fixedly connected to the upper surface of the fixing plate through a mounting frame.

[0008] As a further solution of the utility model: a protective shell is provided on the upper surface of the fixing plate.

[0009] As a further solution of the utility model: a dust suction pipe is passed through the fixing plate, the bottom end of the dust suction pipe is connected to an annular groove, and the annular groove is arranged on the outside of the grinding head.

[0010] As a further solution of the utility model: through holes are provided on the upper surfaces of the fixing plate and the protective shell.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The concrete floor grinding device for building civil engineering projects can effectively prevent dust from escaping when grinding the floor through the arrangement of a fixed plate, a first protective plate, a second protective plate, a moving wheel, a brush, a dust suction pipe and an annular groove. At the same time, the dust on the floor can be cleaned by the brush, which is convenient for adsorbing dust through the dust suction pipe, thereby improving the grinding efficiency of the floor by the staff.

[0013] 2. The concrete floor grinding device for building civil engineering projects, through the arrangement of springs, transmission wheels, transmission belts, fan blades and annular grooves, utilizes the elastic effect of the springs, and cooperates with the arrangement of a single second protective plate to ensure that the device can be moved more conveniently, while effectively avoiding the escape of dust. The arrangement of the transmission wheel and the transmission belt can make the fan blades rotate, which can speed up the circulation of air and make it more convenient for the dust suction pipe to absorb dust, further improving the dust treatment effect. The annular groove is arranged on the outside of the grinding head, and the outer side edge depth of the annular groove is greater than the inner side edge. When the grinding head contacts the ground, small particles generated will splash into the annular groove, making it easier to be absorbed through the dust suction pipe.

[0026] The first bearing 5 and the second bearing 6 are both provided with a first rotating shaft 7 and a second rotating shaft 8, and the surfaces of the first rotating shaft 7 and the second rotating shaft 8 are respectively provided with a first transmission wheel 9 and a second transmission wheel 10, and the first transmission wheel 9 and the second transmission wheel 10 are connected by a transmission belt 11. The arrangement of the first transmission wheel 9, the second transmission wheel 10 and the transmission belt 11 can enable the motor 14 to simultaneously drive the grinding head 12 and the fan blades 13 to rotate, and the surfaces of the first rotating shaft 7 and the second rotating shaft 8 are respectively installed with the grinding head 12 and the fan blades 13, and the lower surface of the second protective plate 3 is fixedly connected with a moving wheel 19 and a brush 20.

[0027] Specifically, the top end of the first rotating shaft 7 is fixedly connected to the surface of the output shaft of the motor 14, and the body of the motor 14 is fixedly connected to the upper surface of the fixed plate 1 through the mounting bracket 15. When the motor 14 is working, the output shaft of the motor 14 can drive the grinding head 12 to rotate through the first rotating shaft 7, so that grinding work can be performed.

[0028] Specifically, a protective shell 16 is provided on the upper surface of the fixing plate 1 , and the motor 14 and the dust suction pipe 17 can be protected by the protective shell 16 , and the protective shell 16 can be connected to an external frame by means of threaded connection.

[0030] Specifically, the upper surfaces of the fixing plate 1 and the protective shell 16 are both provided with through holes 21 . The provision of the through holes 21 can ensure the circulation of air, making it easier for the dust suction pipe 17 to absorb dust.

[0031] The working principle of the utility model is:

[0032] When in use, it is installed on the frame through the protective shell 16. When performing grinding work, the staff can control the motor 14 to work through the control system. The output shaft of the motor 14 drives the grinding head 12 to rotate through the first rotating shaft 7.
