[0002] During the construction of a building, it is necessary to groove and hide all kinds of wires, water pipes and other pipelines to ensure the smoothness and beauty of the building surface, and also improve the safety of the building. During the construction, the groove cutting equipment is generally used to groove the surface of the building first, and then the water and electricity pipelines are installed; Some current construction grooving equipment, such as a patent application with authorization announcement number CN 112895176 B, discloses a building wall grooving device, including a bottom plate, a fixed plate and a soft brush, the bottom of the bottom plate is fixedly connected with a universal wheel, the top of the bottom plate is provided with a third slot, the inner wall of the third slot is fixedly installed with a fixed bracket, and the side of the fixed bracket is provided with a first slide groove. The building wall grooving device, when the grooving depth of the cutting blade is adjusted, pushes the bottom plate and moves the grooving machine to the wall through the universal wheel and opens the grooving machine, so that the cutting blade grooves the wall, the cutting blade can rotate and cut through the provided bearing, and the top plate slides in the first slide groove on the side of the fixed bracket through the provided electric push rod to perform the overall cutting of the wall, so that the worker does not need to hold the grooving device to groove the wall, and avoids the situation that the grooving device falls out of the worker's hand due to physical exhaustion when the worker holds it for a long time, causing injury to the worker, and makes the grooves opened by the worker beautiful and neat.

[0003] For another example, a patent application with the authorization announcement number CN 109176926 B discloses a wall slotting device for construction, including: a transverse adjustment block, a vertical adjustment block, a depth adjustment bolt, a bellows and a vacuum cleaner; the transverse adjustment block is slidably mounted on a slide rail through a groove at its bottom, the vertical adjustment screw rod passes downward through a through hole and is embedded in a bearing on the inner side of the transverse adjustment block, and the vertical adjustment screw rod passes through a vertical threaded hole on the vertical adjustment block, the slotted motor housing is connected to a bellows through the slotted adjustment hole, a dust hood is also provided on the bottom side of the bellows, and a dust suction hose at the bottom of the dust hood is connected to a vacuum cleaner. The slotted motor housing can be adjusted in angle in the slotted adjustment hole, the extended length of the slotted motor housing can be adjusted by the depth adjustment bolt according to the slotting depth requirement, the slotting depth can be adjusted, and the bellows can be used to completely cover the slotted position by utilizing its elasticity; Combined with the current use of slotting equipment in the construction process, we found that the current slotting equipment still has certain disadvantages, such as: 1. Manual operation will generate strong vibration during the slotting and cutting process, which will affect the construction workers' control and is not conducive to maintaining the stability of the slotting; 2. It can only be used for single-sided construction and cannot be used for grooving on walls, floors and other surfaces of different dimensions at the same time; 3. Poor protection ability.

[0022] Wherein: the diagonal brace rod 8 is fixedly connected between the right end of the horizontal support frame 1 and the top of the vertical support frame 2 in an inclined manner, the outer side of the diagonal brace rod 8 is slidably connected with a sliding sleeve 9, and the inner side of the sliding sleeve 9 is rotatably installed with a control panel 10; In a specific application scenario, by connecting the diagonal brace rod 8 to the ends of the transverse support frame 1 and the vertical support frame 2, the strength can be further increased, and by the sliding connection between the sliding sleeve 9 and the diagonal brace rod 8, the height position of the control panel 10 can be adjusted by sliding the sliding sleeve 9, and the control panel 10 can be rotated on the inner side of the sliding sleeve 9, which is convenient for adjusting the angle of the control panel 10, and convenient for the staff to stand directly on the surface of the base plate 4 to operate it, or after flipping it, move the control panel 10 to a position suitable for use.

[0023] Wherein: the mounting frame 11 is vertically slidably connected to the inner side of the vertical support frame 2, a third motor 34 is installed in the middle of the top surface of the top plate 5, the output shaft of the third motor 34 is connected to the second adjustment rod 35, the second adjustment rod 35 is vertically rotatably installed between the bottom plate 4 and the top plate 5, and the second adjustment rod 35 is correspondingly connected to the bottom of the mounting frame 11, and the inner side of the mounting frame 11 is vertically slidably connected to the first slider 14; A first motor 12 is installed in the middle of the top of the installation frame 11, and the output shaft of the first motor 12 is connected to the first adjusting rod 13. The first adjusting rod 13 is installed in the middle of the inner side of the installation frame 11 in a vertically rotatable manner.

The first slider 14 is slidably connected to the inner side of the installation frame 11 through the first slide rail 15 and the slide rod 16.

[0024] In a specific application scenario, the first motor 12 is started to drive the first adjusting rod 13 to rotate, so that the first adjusting rod 13 can drive the first slider 14 to be raised and lowered along the limit of the first slide rail 15 and the slide rod 16, so as to move the cutting blade 22 set on the outside of the first slider 14 in height. At the same time, the second adjusting rod 35 is started by the third motor 34, so that the installation frame 11 can be raised and lowered by the second adjusting rod 35, thereby further increasing the lifting range of the cutting blade 22 to adapt to long-distance grooving.

[0025] Among them: the outer side of the first slider 14 is symmetrically fixedly installed with a second slide rail 17, the outer side of the second slide rail 17 is slidably connected with a second slider 18, a first telescopic rod 19 is fixed to the middle part of the outer side of the first slider 14, and the telescopic end of the first telescopic rod 19 is fixedly connected to the second slider 18, a mounting plate 20 is rotatably installed on the outer side of the second slider 18, a second motor 21 is fixedly installed on the end of the mounting plate 20, the output shaft of the second motor 21 is fixedly connected to the cutting blade 22, a second telescopic rod 23 is rotatably installed on the outer side of the second slider 18, and the telescopic end of the second telescopic rod 23 is correspondingly rotatably connected to the mounting plate 20.

[0026] In a specific application scenario, the extension and retraction of the first telescopic rod 19 can drive the second slider 18 to slide forward and backward on the outside of the second slide rail 17 to adjust the front and rear position of the cutting blade 22. The extension and retraction of the second telescopic rod 23 can pull the mounting plate 20 so that the mounting plate 20 rotates on the outside of the second slider 18, and the angle of the cutting blade 22 can be adjusted to adapt to the opening of different groove types.

[0027] The top of the first sliding block 14 is penetrated by a telescopic tube 24 , and the end of the telescopic tube 24 is connected to a dust box 25 via a pump. The dust box 25 is arranged on the surface of the bottom plate 4 .

[0028] In a specific application scenario, a pump is used to absorb dust generated during the grooving process through the telescopic tube 24 to maintain the on-site environment.

[0029] Among them: the fixed plate 27 is arranged below the first slider 14, and a shell 28 is installed on the top surface of the fixed plate 27, a reel 29 is rotatably installed inside the shell 28, and a shielding cloth 26 is coiled on the outer side of the reel 29, the end of the reel 29 is connected with a coil spring 30, and the reel 29 is elastically connected to the shell 28 through the coil spring 30, the shielding cloth 26 on the outer side of the reel 29 is fixedly connected to the bottom surface of the first slider 14, a third slider 31 is symmetrically fixedly installed on the outer side of the fixed plate 27, and the fixed plate 27 is slidably connected to the outer side of the slide rod 16 through the third slider 31, a damping pad 32 tightly fitting with the slide rod 16 is fixed on the inner side of the third slider 31, a spring 33 is connected to the bottom surface of the third slider 31, and the bottom end of the spring 33 is connected to the bottom surface of the mounting frame 11.

[0030] When the first slider 14 is lifted up, the shielding cloth 26 is pulled by the first slider 14, so that the shielding cloth 26 is unwound on the outside of the reel 29, wherein the fixed plate 27 is slidably connected to the outside of the slide bar 16 by the third slider 31, and the third slider 31 increases the friction with the slide bar 16 through the damping pad 32. When the top of the shielding cloth 26 starts to be pulled up, the fixed plate 27 will not move. After the shielding cloth 26 is rolled up a certain distance, its pulling force is greater than the friction between the damping pad 32 and the slide bar 16, which can drive the fixed plate 27 to slide up synchronously, and it does not affect the unwinding and use of the shielding cloth 26. The shielding cloth 26 can be used for stable protection to prevent sand and gravel from splashing. When the first slider 14 descends, the fixed plate 27 is directly pulled down and reset by the elastic action of the spring 33. When the first slider 14 continues to descend, the reel 29 can synchronously rewind the shielding cloth 26 through the winding spring 30, so as to automatically adapt to different heights.

[0031] Among them: the outer side surface of the vertical support frame 2 and the outer side surface of the installation frame 11 are symmetrically installed with the third telescopic rod 36, and the telescopic end of the third telescopic rod 36 is correspondingly fixedly installed with the second universal wheel 37 in a specific application scenario.

[0032] In specific application scenarios, such as Figure 1 When the device is vertically placed for slotting, the second universal wheel 37 is adapted to the wall surface by the extension and contraction of the third telescopic rod 36, which can help maintain the device in stable use. Fig. 9 When the middle level slot is opened, the slot depth can be adjusted by extending and retracting the third telescopic rod 36, which is convenient for slot opening.
