[0023] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0024] See also Figure 1-6 The present invention provides an implementation scheme: In the modern building wall treatment process, the wall needs to be polished first. At the current stage, the wall polishing construction, whether manual construction or machine automatic polishing, is not equipped with corresponding polishing and dust removal equipment. Therefore, during the polishing process, it is easy to cause the problem of fly ash on the wall flying everywhere, thereby affecting and endangering the physical and mental health of the construction workers and increasing the workload of the construction workers.

[0025] In view of the above problems, the present application discloses a wall surface grinding device for construction, which adopts an automatic grinding method, wherein a support base 1 equipped with a moving component 11 is used as a support base, and the bottom of the support base 1 is provided with a moving component 11, and the moving component 11 adopts an automatic moving structure, which provides a horizontal movement method of the equipment during the grinding process, and then a fixed frame 2 is provided on the support base 1, and the fixed frame 2 is used as the installation basis of various functional components, and the various functional components are protected by the fixed frame 2, and then a guide rail 3 is provided on the fixed frame 2, and the guide rail 3 and the guide plate 4 adopt a rail matching, and the guide plate 4 is guided and controlled by the guide rail 3, so as to realize the lifting control of the grinding operation, and a grinding mechanism 5 is provided on the guide plate 4; Furthermore, a negative pressure adsorption separation device 6 is provided on one side of the grinding mechanism 5 on the guide plate 4, and a negative pressure controller 7 is provided on the support base 1. The negative pressure controller 7 cooperates with the negative pressure adsorption separation device 6 to adsorb dust generated by grinding. The negative pressure controller 7 can generate negative pressure suction. During the grinding process, the debris and flying dust generated by grinding the wall surface enter the negative pressure controller 7 under the action of the negative pressure suction. The negative pressure controller 7 can separate the gas from the flying dust to ensure the building environment around the construction. According to the instruction manual Figure 1-6 It can be seen that the above-mentioned grinding mechanism 5 includes a grinding power assembly 51, which is arranged on the guide plate 4, and a control gear box 52 is connected to one side of the grinding power assembly 51, and a grinding feed controller 53 is connected to the control gear box 52, and a grinding disc 54 is connected to the grinding feed controller 53; In the specific implementation process, the power for grinding is provided by the grinding power assembly 51, which provides power to the control gear box 52 and improves the output torque. The grinding feed controller 53 can control the grinding feed amount of the grinding disc 54. The feeding amount of the grinding disc 54 can be controlled by the grinding feed controller 53. The power provided by the grinding power assembly 51 is amplified by the control gear box 52 to make the grinding feed controller 53 rotate, so that the grinding feed controller 53 drives the grinding disc 54 to rotate, so that the grinding disc 54 grinds the wall surface to remove burrs and uneven positions; Furthermore, the fixed frame 2 is a rectangular frame, and a lifting controller 8 is provided on the guide track 3. The lifting controller 8 is connected to the guide plate 4. The lifting controller 8 can control the lifting of the guide plate 4, so that the guide plate 4 drives the grinding mechanism 5 and the negative pressure adsorption separation device 6 to move synchronously, thereby completing the grinding and separation adsorption of the wall surface; The supporting base 1 can be moved along the wall by the moving assembly 11, and the lifting controller 8 is used to control the lifting movement of the guide plate 4 to achieve the polishing of the entire wall surface; According to the instruction manual Figure 1-6 It can be known that the above-mentioned negative pressure adsorption separation device 6 includes a negative pressure deflector 61, the opening of the negative pressure deflector 61 is a trumpet-shaped structure, and the negative pressure deflector 61 is coaxially assembled on the grinding disc 54. The air intake volume is increased through the trumpet opening of the negative pressure deflector 61, and then the negative pressure deflector 61 is coaxially arranged with the grinding disc 54, and the outer periphery of the grinding disc 54 is connected with the negative pressure deflector 61 through the opening structure, and then the negative pressure deflector 61 is used to adsorb the fly ash generated by grinding from the negative pressure adsorption separation device 6.

[0026] Furthermore, the support base 1 is a rectangular structure plate, and the support base 1 and the fixed frame 2 are connected in a split manner. A pushing handrail 12 is provided on one side of the support base 1. The support base 1 can be pushed to move by pushing the handrail 12, which is convenient for layer operation during transportation.

[0027] According to the instruction manual Figure 1-6 It can be seen that the above-mentioned moving assembly 11 includes a moving motor 111, which is assembled on the supporting base 1. Two pairs of rollers 112 are arranged on both sides of the supporting base 1. The two pairs of rollers 112 and the driving end of the moving motor 111 are driven by a gear set 113. A guide roller 114 is arranged on one side of the supporting base 1. In the specific implementation process, the mobile motor 111 can drive the gear set 113 to rotate the two pairs of rollers 112 in linkage, so that the two pairs of rollers 112 can rotate, and the two pairs of rollers 112 can drive the support base 1 to move. A guide roller 114 is set on one side of the support base 1, and a reference rod is set on one side of the wall. The guide roller 114 contacts the reference rod, which can effectively support the distance between the base 1 and the wall and keep the horizontal movement of the equipment stable.

[0028] According to the instruction manual Figure 1-3 It can be seen that the negative pressure adsorption separation device 6 further includes a separation air inlet pipe 62, one end of the separation air inlet pipe 62 is connected to the negative pressure deflector 61, and the other end of the separation air inlet pipe 62 is connected to the negative pressure controller 7, and the end opening of the negative pressure deflector 61 is connected to the outer periphery of the grinding disc 54; During the specific implementation process, when the grinding disc 54 is rotating, most of the debris and flying dust generated by grinding are thrown outward, so a number of air guide ports 63 are arranged in a ring array on the outer circumference of the grinding disc 54, and the end opening of the negative pressure deflector 61 is connected to the number of air guide ports 63. Through the negative pressure diversion effect of the negative pressure deflector 61, the debris and flying dust are passed from the air guide ports 63 to the side of the negative pressure controller 7. Through the separation air inlet pipe 62, it can play a connecting and diverting role with the end of the negative pressure deflector 61, and the material is discharged to the side of the negative pressure controller 7.

[0029] According to the instruction manual Figure 1-6 It can be seen that the negative pressure controller 7 includes a negative pressure suction motor 71, which is mounted on the support base 1. The driving end of the negative pressure suction motor 71 is connected to a negative pressure pump housing 72, and an air inlet 73 is provided on one side of the negative pressure pump housing 72. A filter 74 is connected to one side of the air inlet 73, and a telescopic transfer pipe 75 is connected to one side of the filter 74. The telescopic transfer pipe 75 is a hard multi-stage telescopic pipe 531. The end of the separation air inlet pipe 62 is connected to the telescopic end of the telescopic transfer pipe 75, and the bottom end of the telescopic transfer pipe 75 is connected to the filter 74. During the specific implementation process, the fan blades in the negative pressure pump housing 72 are driven to rotate by the negative pressure suction motor 71, thereby generating a negative pressure effect. The negative pressure effect is connected to the filter 74 through the air inlet 73, and negative pressure is generated on one side of the filter 74. Then, this negative pressure effect is transmitted through the telescopic transfer tube 75 and the separation air inlet pipe 62, so that the fly ash entering the grinding disc 54 enters the telescopic transfer tube 75 from the separation air inlet pipe 62. The multi-stage telescopic structure of the telescopic transfer tube 75 is utilized. Since the telescopic transfer tube 75 adopts a hard multi-stage telescopic tube 531, and the separation air inlet pipe 62 is also a hard structure, the telescopic trajectory movement of the telescopic transfer tube 75 is also relatively fixed, thereby avoiding interference with the grinding mechanism 5.

[0030] According to the instruction manual Figure 1-6 It can be known that the above-mentioned grinding power assembly 51 includes a motor frame 511, which extends integrally from one side of the guide plate 4. The motor frame 511 is connected to a driving motor 512. In the specific implementation process, the driving motor 512 is installed through the motor frame 511, and the driving motor 512 is used as a specific power source.

[0031] According to the instruction manual Figure 1-6 It can be seen that the control gear box 52 includes a gear box body 521, which is mounted on the guide plate 4. A transmission gear set 522 is provided in the gear box. The input end of the transmission gear set 522 is connected to the driving end of the driving motor 512, and the output end of the transmission gear set 522 is provided with a control cylinder 523. In the specific implementation process, the gear box body 521 is used as the structural body of the control gear box 52, and the transmission gear group 522 inside the gear box body 521 plays the role of transmitting and increasing the torque. The rotational torque is transmitted from one side of the control cylinder 523, and then the control cylinder 523 is used to drive the grinding feed controller 53 to rotate.

[0032] According to the instruction manual Figure 1-6 It can be known that the above-mentioned grinding feed controller 53 includes a telescopic tube 531, which is assembled in the control cylinder 523. The end of the telescopic tube 531 is connected to the grinding disc 54. The telescopic tube 531 is a cylindrical pipe fitting. A shaft key extends from one side of the telescopic tube 531. A shaft key sleeve is provided on the inner side of the control cylinder 523, and the shaft key sleeve is engaged with the shaft key. One end of the telescopic tube 531 is connected to a control track 532, and a pushing slider 533 is provided on the control track 532. A rotating shaft sleeve 534 is provided on the pushing slider. The rotating shaft sleeve 534 is movably connected to the end of the telescopic tube 531. A control screw 535 is provided on the control track 532, and the control screw 535 is threadedly engaged with the pushing slider 533.

[0033] During the specific implementation process, the telescopic tube 531 is inserted into the control cylinder 523, and the telescopic tube 531 and the control cylinder 523 realize power transmission through the cooperation of the shaft key and the shaft key sleeve. The rotation of the control cylinder 523 synchronously drives the telescopic tube 531 to rotate, and then drives the grinding disc 54 to rotate, thereby realizing the function of power transmission. At the same time, in order to adjust the feed amount of the grinding disc 54, the control screw 535 is rotated by rotating, and then the control screw 535 is engaged with the pushing slider 533 to make the pushing slider 533 move linearly, and the rotating shaft sleeve 534 moves linearly, and cooperates with the end of the telescopic tube 531 to axially push the telescopic tube 531 to move, so that the telescopic tube 531 drives the grinding disc 54 to control the feed amount.

[0034] From the above, it can be generally known that the wall grinding device for construction adopts a movable base arranged on one side of the wall and moves parallel to the wall. The movable base drives the guide track 3 to make horizontal movement, and cooperates with the guide track 3 to drive the guide plate 4 to rise and fall, so as to grind the entire wall. Then, a grinding mechanism 5 and a negative pressure adsorption and separation device 6 are arranged on the guide plate 4 to move synchronously. Then, the negative pressure adsorption and separation device 6 can be used to negatively adsorb and separate the grinding dust. The negative pressure adsorption and separation device 6 is coaxially arranged with the grinding mechanism 5 and is a telescopic tube 531 made of hard material to avoid interference with the grinding mechanism 5. The structure is simple and the environment of the grinding operation is effectively protected.
