Description

Technical Field

[0001] The utility model belongs to the technical field of grinding wheels, in particular to a template grinding grinding wheel machine. Background Art

[0002] The construction of large cantilever cap beams is an efficient and commonly used construction technology for large-span bridges. Before pouring concrete, formwork is required to support the formwork, and then concrete is poured into the formwork. The inner surface of the formwork needs to be polished smooth and bright with a grinding wheel machine. If the misalignment at the formwork joints is large, the misalignment needs to be repeatedly polished to make it smooth.

[0003] In the existing technology, the operator holds the handle and grinds the template surface through the rotating grinding wheel on the machine body. The debris and dust generated in the grinding process will splash and drift outward through the rotating grinding wheel, resulting in a lot of debris and dust on the template surface and the surrounding area. On the one hand, it is difficult to clean, and on the other hand, the flying debris can easily hit people, reducing the operator's operating experience. For this reason, we propose a template grinding wheel machine. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] See also Figure 1-Figure 5 The present invention provides a technical solution: a template grinding machine, comprising a machine body 100 and a grinding wheel body 103 arranged at the bottom of the machine body 100, a protective component is provided at the bottom of the machine body 100, and the protective component includes a transparent protective cover 202, which can block and protect flying debris and floating dust;

[0029] The bottom of the transparent protective cover 202 is provided with multiple sets of rubber curtains 204, which can block and protect the area at the bottom of the transparent protective cover 202. The bottom inner wall of the transparent protective cover 202 is fixed with multiple sets of support columns 207, and the bottom of the support columns 207 is provided with rolling balls 208, which can roll on the template surface;

[0030] A fixing ring 201 is fixed to the outside of the body 100, and a fixing tube 205 is embedded in the inside of the fixing ring 201. A fixing rod 203 is slidingly set inside the fixing tube 205. The bottom of the fixing rod 203 is fixedly connected to the transparent protective cover 202, and an upper circular plate 200 is fixed to the outside of the top of the fixing rod 203. A connecting spring 206 is also sleeved on the outside of the fixing rod 203. The top of the connecting spring 206 is fixedly connected to the upper circular plate 200, and the bottom of the connecting spring 206 is fixedly connected to the fixing ring 201. When the thickness of the grinding wheel body 103 decreases and becomes thinner, the connecting spring 206 stretches to cause the upper circular plate 200 to generate a downward force to drive the rubber curtain 204 at the bottom of the transparent protective cover 202 to keep in contact with the surface of the template.

[0031] The utility model is designed with a protective component. When the high-speed rotating grinding wheel is in use, the transparent protective cover 202 and the rubber curtain 204 at the bottom can block the flying debris and the floating dust, reducing the flying of debris and the floating of dust, and facilitating cleaning. At the same time, the transparent protective cover 202 and the rubber curtain 204 can adaptively rise and fall under the action of the connecting spring 206, so that they always cover the grinding wheel body 103 to reduce the flying of debris and the floating of dust. Moreover, the situation of the grinding wheel body 103 during the grinding process of the template can be seen through the transparent protective cover 202, which improves the operating experience of the operator.

[0032] Example 2

[0033] Based on Example 1, please refer to Figure 2-Figure 6 The bottom inner wall of the transparent protective cover 202 is provided with a cleaning piece for cleaning dust and debris attached to the bottom inner wall of the transparent protective cover 202. The cleaning piece includes a support bearing 302 and a brush 303. The support bearing 302 is composed of an inner ring and an outer ring. The lower ring 301 is fixed on the inner ring, and the outer ring is fixed on the support column 207. The outer wall of the support bearing 302 is fixedly connected to the support column 207. The bottom of the support bearing 302 is fixedly provided with a lower ring 301, and the brush 303 is fixed on the inner wall of the lower ring 301.

[0034] A sealed bearing is embedded in the interior of the transparent protective cover 202, and a rotating shaft is set inside the sealed bearing. A rotating wheel 304 is fixed at the bottom of the rotating shaft. The rotating rotating wheel 304 drives the inner ring of the supporting bearing 302 to rotate, and then drives the lower ring 301 to rotate. The outer wall of the rotating wheel 304 contacts the inner wall of the supporting bearing 302. A reduction motor 300 is fixed on the top of the transparent protective cover 202, and the working end of the reduction motor 300 is fixedly connected to the top of the rotating shaft.

[0035] The cleaning part designed in the present invention starts the reduction motor 300 to drive the strip brush 303 to rotate and clean the debris and dust on the inner wall when debris and dust adhere to the bottom inner wall of the transparent protective cover 202 and affect the line of sight, so that the operator can see clearly the condition of the grinding wheel body 103 grinding the template.

[0036] In this embodiment, a wire 102 is provided on the top of the body 100 , and a handle 101 is provided on the outside of the body 100 .

[0037] The working principle and use process of this utility model:

[0038] When the present invention is in use, the high-speed rotating grinding wheel body 103 grinds the surface of the template during grinding. The debris and dust generated during the grinding process will be blocked by the transparent protective cover 202 and the multiple groups of rubber curtains 204 at the bottom, reducing the splashing of debris and the floating of dust. When the thickness of the grinding wheel body 103 decreases during the grinding process, the transparent protective cover 202 can generate a downward moving force under the action of the connecting spring 206, and can be adaptively raised and lowered according to the thickness of the grinding wheel body 103, so that the bottom of the multiple groups of rubber curtains 204 at the bottom of the transparent protective cover 202 can always contact the surface of the template. At the same time, during the grinding movement, the ball 208 at the bottom of the support column 207 rolls on the template surface, reducing the wear on the bottom of the rubber curtain 204.

[0039] During the grinding process, the reduction motor 300 is turned on to drive the rotating shaft and the rotating wheel 304 to rotate, which in turn drives the inner wall of the support bearing 302 to rotate, and drives the lower ring 301 and the strip brush 303 fixed on the lower ring 301 to rotate. At this time, the strip brush 303 can sweep away the debris and dust attached to the inner wall of the bottom of the transparent protective cover 202, reducing the situation where the debris and dust affect the line of sight.

[0040] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
