Detailed Embodiments

[0025] The present invention will be further described below in conjunction with the embodiments shown in the drawings.

[0026] Embodiment 1

[0027] A wall grooving method includes the following steps:

[0028] Step 1: Manually draw a preset cutting line on the ceiling 1;

[0029] Step 2: Use the wall grooving equipment for building construction to cut out two parallel cutting grooves 11 on the ceiling 1;

[0030] Step 3: Manually hammer the concrete between the two grooving slots 11 using a hammering tool.

[0031] As Figures 1-5 shown, the wall grooving equipment for building construction described in Step 2 of a wall grooving method includes a vehicle body 2; the vehicle body 2 is electrically driven;

[0032] It also includes an electric push rod I 103, a connecting plate 104, a collecting hopper 105, a telescopic plate 106, an electric drive shaft 107, a cutting tool 108, an electric push rod II 109, a hammering tool 1010, a stabilizing assembly, and a cooling assembly; the vehicle body 2 is bolted with the electric push rod I 103; the telescopic end of the electric push rod I 103 is fixedly connected with the connecting plate 104; the connecting plate 104 is connected with the collecting hopper 105; the collecting hopper 105 is slidably connected with four telescopic plates 106, and a spring is arranged between the telescopic plate 106 and the collecting hopper 105; the collecting hopper 105 is rotatably connected with the electric drive shaft 107; the electric drive shaft 107 is connected with two cutting tools 108, and the cutting tools 108 are located inside the collecting hopper 105; an electric push rod II 109 is fixedly connected inside the collecting hopper 105; the telescopic end of the electric push rod II 109 is fixedly connected with the hammering tool 1010; the vehicle body 2 and the connecting plate 104 are jointly connected with the stabilizing assembly; the collecting hopper 105 is connected with the cooling assembly.

[0033] The stabilizing assembly includes a cylinder 101 and an electric vehicle 102; the vehicle body 2 is bolted with the cylinder 101; the telescopic end of the cylinder 101 is fixedly connected with the electric vehicle 102, and the electric vehicle 102 is slidably connected with the connecting plate 104.

[0034] The cooling assembly includes a spray pipe 1011, a cooling pipe 1012, and a spray head 1013; two spray pipes 1011 are fixedly connected inside the collecting hopper 105; each spray pipe 1011 is communicated with a cooling pipe 1012; the collecting hopper 105 is fixedly connected with two staggeredly arranged spray heads 1013, and the spray heads 1013 are located between the two cutting tools 108, and the spray heads 1013 face the corresponding cutting tools 108.

[0035] It also includes a camera 1015; the collecting hopper 105 is fixedly connected with the camera 1015, and by observing through the camera 1015, it is ensured that the trajectory of the cutting tool 108 coincides with the line 12 to ensure accurate grooving.

[0036] There are two electric push rods II 109 and hammering tools 101, and the two electric push rods II 109 are arranged in a staggered manner, increasing the hammering force of the hammering tool 1010 on the concrete between the two grooving slots 11 and improving the hammering efficiency.

[0037] During use, first connect the external pump to the nozzle 1011 and the nozzle head 1013 through pipelines. Then, control the electric push rod I 103 to drive the connecting plate 104 and the parts thereon to move upward. At the same time, control the electric drive shaft 107 to drive the cutting knife 108 to rotate counterclockwise from the front view, so that the cutting knife 108 cuts into the ceiling 1 upward to a predetermined depth. It should be noted that after the telescopic plate 106 contacts the ceiling 1, it slides on the collection hopper 105, and the spring is compressed, protecting the debris generated during grooving through the telescopic plate 106. Subsequently, control the vehicle body 2 to drive the electric push rod I 103 and the connected parts to the right, so that the cutting knife 108 cuts a cutting groove 11 to the right along the pre-drawn line 12 on the ceiling 1. During the grooving process, control the external pump to start, spray cooling water to the area between the two cutting knives 108 through the staggered nozzle heads 1013 for cooling, and spray atomized cooling water to the front and rear sides of the two cutting knives 108 through the nozzle 1011, and spray cooling water to the area where the cutting knife 108 contacts the ceiling 1 through the cooling pipe 1012, so as to bring the cooling water into the cutting groove 11 during the rotation of the cutting knife 108 and cool the area of the cutting knife 108 inside the cutting groove 11; it should be noted that during the process of the vehicle body 2 driving the electric push rod I 103 and the connected parts to the right, since there is a certain height between the ground and the ceiling 1 and the telescopic plate 106 is in close contact with the ceiling 1, simply driving the electric push rod I 103 and the connected parts to the right by the vehicle body 2 will cause unstable movement and affect the grooving work. Therefore, a cylinder 101 is added to the vehicle body 2, an electric vehicle 102 is added to the telescopic end of the cylinder 101, and the electric vehicle 102 is slidably connected to the connecting plate 104. During the process of the electric push rod I 103 driving the connecting plate 104 and the parts thereon to move upward, control the telescopic end of the cylinder 101 to drive the electric vehicle 102 to move upward. After the wheels of the electric vehicle 102 are pressed tightly against the ceiling 1, the electric push rod I 103 continues to drive the connecting plate 104 and the parts thereon to move upward, and the electric vehicle 102 and the connecting plate 104 generate relative sliding, so that during the process of the vehicle body 2 driving the electric push rod I 103 and the connected parts to the right, synchronously control the electric vehicle 102 to drive the connecting plate 104 and the parts thereon to move to the right, and ensure stable movement by driving parts such as the cutting knife 108 synchronously by the vehicle body 2 and the electric vehicle 102.

[0038] After two cutting grooves 11 are cut out by two cutting knives 108, during the process of continuing to cut grooves as the two cutting knives 108 move forward, the telescopic end of the electric push rod II 109 is controlled to drive the hammering knife 1010 to obliquely reciprocate and extend into the cutting groove 11, hammering down the concrete between the two cutting grooves 11. The fallen concrete debris and the sewage generated by cooling fall into the collecting hopper 105 under the limiting action of the telescopic plate 106 for collection. Compared with the existing method of first cutting two cutting grooves 11 on the ceiling 1 and then manually hammering down the concrete between the two cutting grooves 11, the present invention can realize automatic grooving, and automatically hammer down the concrete between the two cutting grooves 11 during the grooving process, reducing the manual workload and improving the grooving efficiency. Moreover, the collecting hopper 105 timely collects the debris and sewage generated during the grooving process, preventing the debris and sewage from falling to the ground and increasing the subsequent cleaning cost.

[0039] Embodiment 2

[0040] On the basis of Embodiment 1, as Figure 3 and Figure 4 shown, it further includes an electric push rod III 201, a baffle 202, a rotating rod 203, a motor 204, a limiting rod 205 and a retaining piece 206; the electric push rod III 201 is bolted inside the collecting hopper 105; the telescopic end of the electric push rod III 201 is fixedly connected with the baffle 202; the baffle 202 is rotatably connected with the rotating rod 203; the baffle 202 is fixedly connected with the motor 204, and the output shaft of the motor 204 is fixedly connected with the rotating rod 203; the baffle 202 is fixedly connected with several limiting rods 205; two elastic retaining pieces 206 are wound around the rotating rod 203, and the retaining pieces 206 are located between the limiting rods 205 and the baffle 202.

[0041] The retaining piece 206 is provided with a bent end 2061, and the end 2061 is arranged with a smaller upper part and a larger lower part. The bent end 2061 can increase the buffering effect of the retaining piece 206 on the splashing sewage, improve the blocking effect of the retaining piece 206 on the sewage, and at the same time, the end 2061 with a smaller upper part and a larger lower part is convenient for the retaining piece 206 to extend into the cutting groove 11.

[0042] Although the splashed sewage and debris can be intercepted by the cooperation of the collecting hopper 105 and the telescopic plate 106, after the cutting groove 11 is cut by the cutter 108, the sewage and debris will fly out along the cutting groove 11 under the high-speed drive of the cutter 108, and the collecting hopper 105 and the telescopic plate 106 cannot effectively intercept the sewage and debris flying out from the cutting groove 11. Therefore, when the cutter 108 moves upward and cuts into the ceiling 1, the control electric push rod III 201 drives the baffle 202 to move upward until the upper side of the baffle 202 contacts the ceiling 1. After the cutter 108 cuts out the cutting groove 11, the control motor 204 is started, and the output shaft of the motor 204 drives the rotating rod 203 to rotate. The rotating rod 203 winds out the retaining piece 206 upward, so that the retaining piece 206 extends into the cutting groove 11 until the retaining piece 206 contacts the top of the cutting groove 11. The retaining piece 206 blocks the splashed sewage and debris from the cutting groove 11, preventing the sewage and debris in the cutting groove 11 from flying out under the high-speed drive of the cutter 108. It should be noted that the height of the retaining piece 206 can be adjusted according to the depth of the cutting groove 11, so that the retaining piece 206 adapts to the depth of the cutting groove 11.

[0043] Embodiment 3

[0044] On the basis of Embodiment 2, as Figures 3-5 shown, it further includes an electric push rod IV 301, a push plate 302, a rectangular plate 303 and a dial block 305; one of the cutters 108 is slidably connected to the electric drive shaft 107 by a spline; one of the cutters 108 is provided with an annular groove 1081; the collecting hopper 105 is fixedly connected with the electric push rod IV 301, and the telescopic end of the electric push rod IV 301 penetrates through the collecting hopper 105 and is slidably connected with the annular groove 1081; a rectangular groove is provided on the baffle 202; the baffle 202 is slidably connected with the push plate 302, and the push plate 302 slides in the rectangular groove of the baffle 202; a chute 3021 is provided on the push plate 302; the telescopic end of the electric push rod IV 301 is fixedly connected with the rectangular plate 303, and the rectangular plate 303 slides in the chute 3021; the push plate 302 is fixedly connected with a plurality of dial blocks 305, and the dial blocks 305 are slidably connected with the rotating rod 203 and the limiting rod 205, and one of the retaining pieces 206 is slidably connected with the rotating rod 203; the retaining piece 206 slidably connected with the rotating rod 203 contacts the dial block 305.

[0045] It further includes a motor 304; the connecting plate 104 is rotatably connected with the collecting hopper 105; the connecting plate 104 is bolted with the motor 304, and the output shaft of the motor 304 is fixedly connected with the collecting hopper 105.

[0046] When the width of the grooving is relatively large, it is necessary to adjust the distance between the two cutting grooves 11, that is, to adjust the distance between the two cutting knives 108. At this time, control the telescopic end of the electric push rod Ⅳ 301 to drive one of the cutting knives 108 to move, thereby adjusting the distance between the two cutting knives 108. The telescopic end of the electric push rod Ⅳ 301 simultaneously drives the rectangular plate 303 to move horizontally. The rectangular plate 303 drives the push plate 302 to slide in the rectangular groove opened on the baffle 202. The push plate 302 drives the block 305 to slide on the rotating rod 203 and the limiting rod 205, so that the block 305 drives the corresponding retaining piece 206 to move on the rotating rod 203, so as to adjust the distance between the two retaining pieces 206 and make the retaining piece 206 and the cutting knife 108 face each other. When the normal cutting knife 108 rotates, the telescopic end of the electric push rod Ⅳ 301 slides in the annular groove 1081. When the electric push rod Ⅲ 201 drives the baffle 202 and the parts thereon to move upward, the rectangular plate 303 slides in the chute 3021.

[0047] When the cutting knife 108 moves to the corner of the ceiling 1, at this time, since the hammering knife 1010 is on the left side of the cutting knife 108, after the cutting knife 108 has cut out all the cutting grooves 11, the hammering knife 1010 has not yet hammered down all the concrete between the two cutting grooves 11. Therefore, first control the electric push rod Ⅰ 103 to drive the connecting plate 104 and the parts thereon to move downward, so that the cutting knife 108 is separated from the ceiling 1. Then, control the motor 304 to start, and drive the collecting hopper 105 and the parts thereon to rotate 180 degrees through the output shaft of the motor 304, so that the hammering knife 1010 is located at the right end of the cutting groove 11, as Figure 5 shown. Then, control the electric push rod Ⅱ 109 to drive the hammering knife 1010 to move upward, so that the hammering knife 1010 extends into the cutting groove 11. Subsequently, control the electric vehicle 102 to drive the connecting plate 104 and the parts thereon to move to the left. At the same time, control the electric push rod Ⅱ 109 to drive the hammering knife 1010 to move reciprocally, so that the hammering knife 1010 hammers down the remaining concrete between the two cutting grooves 11.

[0048] The above are only examples of the present invention and are not used to limit the present invention. All equivalent replacements made within the principle of the present invention shall be included in the protection scope of the present invention. The content not elaborated in detail in the present invention belongs to the prior art well known to those skilled in the art.
