Description

[Technical field]

[0001] The utility model relates to the technical field of grinding robots, in particular to a portable magnetic-absorption type automatic grinding robot for embedded plates. [Background technology]

[0002] There is a large demand for high-altitude work in the construction of embedded plates inside the nuclear island. At present, the construction of embedded plates inside the nuclear island still relies mainly on human work. In the actual construction process, due to the generally high ceilings in the nuclear island, workers need to set up scaffolding and climb up the scaffolding to perform high-altitude work, which can easily cause people to fall and threaten their safety. At the same time, during conventional grinding operations, the grinding equipment has no dust collection function, and the dust generated during the operation will endanger the health of personnel. Although some personnel will wear masks during work, in the environment of poor air flow in the nuclear island, wearing masks will greatly reduce the comfort of personnel at work, and there is no need to effectively prevent the harm of dust.

[0003] Of course, with the continuous development of science and technology, in order to free people from dangerous high-altitude operations, grinding robots have been developed, such as a remote-controlled wall grinding device disclosed in the Chinese utility model patent application number 201420194461.2.

[0054] The guide electric push rod 12 is installed on the movable adjustment mechanism 2, and the output end of the guide electric push rod 12 is set toward the movable opening 41, and the movable mounting seat 14 is connected to the output end of the guide electric push rod 12, so as to use the guide electric push rod 12 to adjust the pressure of the grinding plate 11 on the grinding position; the elastic floating component 15 is connected to the movable mounting seat 14, and the drive motor 13 is set on the elastic floating component 15, and the output end of the drive motor 13 is set toward the movable opening 41, and the grinding plate 11 is connected to the output end of the drive motor 13, so as to use the drive motor 13 to drive the grinding plate 11 to rotate to achieve grinding.

[0055] The utility model arranges a driving motor 13 on an elastic floating component 15, and connects the grinding sheet 11 to the output end of the driving motor 13, so that when the driving motor 13 drives the grinding sheet 11 to rotate and grind, the grinding sheet 11 can float freely within a certain range under the action of the elastic floating component 15, thereby achieving a more efficient and better grinding effect; at the same time, the elastic floating component 15 is connected to the output end of the guide electric push rod 12 through the movable mounting seat 14, so that during operation, the telescopic activity of the guide electric push rod 12 can be used to adjust the pressure of the grinding sheet 11 on the grinding position, thereby adjusting the grinding torque of the grinding sheet 11.

[0056] More specifically, in order to achieve the floating effect, the elastic floating assembly 15 includes a floating plate 151, a floating column 152 and a floating spring 153;

[0057] The driving motor 13 is arranged on a floating plate 151, and a plurality of floating columns 152 are arranged on the floating plate 151 around the driving motor 13; one end of each of the floating columns 152 is fixedly connected to the floating plate 151, and the other end of each of the floating columns 152 passes through the movable mounting seat 14 and is provided with a limiter 154, and the floating column 152 can move up and down relative to the movable mounting seat 14; the outside of each of the floating columns 152 is sleeved with the floating spring 153, one end of the floating spring 153 abuts against the movable mounting seat 14, and the other end of the floating spring 153 abuts against the floating plate 151.

At the same time, a threaded section (not shown) is formed at the other end of the floating column 152, and the limiting member 154 adopts a nut, and the nut is screwed on the threaded section. In this way, not only can the other end of the floating column 152 be limited to ensure that the other end of the floating column 152 will not be separated from the movable mounting seat 14, but also the compression amount of the floating spring 153 can be adjusted by rotating the limiting member 154 to better meet the actual use requirements.

[0059] More specifically, the floating grinding mechanism 1 further includes a vertical guide column 16 and a vertical guide sleeve 17; the vertical guide sleeve 17 is fixed to the movable adjustment mechanism 2, one end of the vertical guide column 16 is connected to the movable mounting seat 14, and the other end of the vertical guide column 16 is slidably assembled in the vertical guide sleeve 17.

In addition, it should be noted that the electric guide rail is a very mature product in the prior art, and the X-axis electric slide rail 21 and the Y-axis electric slide rail 22 can directly adopt the existing electric guide rails, and their specific structures and working principles are well known to those skilled in the art, so the X-axis electric slide rail 21 and the Y-axis electric slide rail 22 will not be introduced in detail here.

[0067] For more details, please refer to Figure 5 As shown, a dust box 46 is detachably provided on the inner side of the flip cover 43. In a specific implementation, the dust box 46 can be provided on a side of the flip cover 43 near the buckle structure 45. Considering the weight of the whole machine to be carried and the convenience of disassembly, the utility model adopts a detachable dust box 46 provided on the inner side of the flip cover 43, so that after the grinding is finished, the operator can tilt the entire grinding robot 100 so that most of the dust enters the dust box 46 under the action of gravity, and manually open the flip cover 43 to clean the dust box 46 and the dust trapped on the inner side of the flip cover 43.

[0069] When the utility model is used in a specific application, the grinding robot 100 can be used to perform construction work on the embedded plate inside the nuclear island (the embedded plate is a steel plate). The specific process is as follows: the operator manually adjusts the position of the electromagnet 31 of the adjustable adsorption mechanism 3 so that the electromagnet 31 can be reliably adsorbed on the embedded plate inside the nuclear island; after the adjustment is completed, the operator manually grabs the grinding robot 100 to the embedded plate inside the nuclear island, and makes the electromagnet 31 of the adjustable adsorption mechanism 3 fit with the embedded plate inside the nuclear island, and at the same time controls the electromagnet 31 to be energized so that the entire grinding robot 100 is adsorbed on the embedded plate inside the nuclear island; controls the mobile adjustment mechanism 2 to drive the floating grinding mechanism 1 to perform a specific grinding operation, and after the grinding is completed, the operator manually grabs the grinding robot 100 and controls the electromagnet 31 to be powered off to achieve the removal of the grinding robot 100.
