Description

Technical Field

[0002] When installing air-conditioning equipment, it is necessary to drill holes in the wall to assist the connection of the corresponding air-conditioning outdoor unit pipeline. At present, drilling is mainly assisted by a drilling device. For example, the Chinese patent with the authorization announcement number "CN218227288U" discloses a drilling device for installing air-conditioning equipment, including a transmission box, a connecting pipe is rotatably connected at the center of the transmission box, a connecting cover is fixedly connected to one end of the connecting pipe, a drill tube is fixedly connected to the side of the connecting cover away from the connecting pipe, a cooling partition is opened inside the barrel wall of the drill tube, a plurality of cooling fins are fixedly connected at the center of the inner wall of the cooling partition, a sealing cover is rotatably connected to one end of the connecting pipe away from the connecting cover, and a drain pipe is fixedly connected to the top of the sealing cover. By setting a cooling partition and a water supply pipe, this scheme can inject cooling water into the cooling partition, so that the high temperature generated by the drilling of the drill tube can be conducted to the inner wall, and cooling is achieved by cooling water. The heated cooling water is at the top, and hot water can be automatically discharged through the drain pipe to achieve circulating cooling. In this way, while ensuring cooling, the cooling water is prevented from flowing to the wall surface and polluting the wall.

The gear box 3 is used to reduce the power of the drill tube driving mechanism 8 and stagger the drill tube driving mechanism 8 and the drill tube body 2, so as to facilitate the installation of a fixing rod 10 in the drill tube body 2 to assist in fixing the whole machine.

[0038] A control display 402 is installed on the upper support plate 4, an upper limit switch 401 matching with the bottom of the upper cover assembly 5 is provided on the upper end surface of the upper support plate 4, and a lower limit switch 301 matching with the base 1 is provided on the lower part of the gear box 3.

When the upper limit switch 401 and the lower limit switch 301 touch an obstacle, the mobile drive mechanism 311 and the drill tube drive mechanism 8 can be controlled to stop working.

[0039] like Fig. 9 As shown, the upper cover assembly 5 includes a fixing plate 503, a mounting groove 504 matching the control display 402 is provided on the fixing plate 503, an upper cover body 502 is fixedly connected above the fixing plate 503, and a display screen 501 corresponding to the control display 402 is provided on the upper cover body 502. In the initial state, the gear box 3, the drill tube driving mechanism 8 and the upper supporting plate 4 can be driven to rise by the mobile driving mechanism 311, so that the control display 402 extends into the mounting groove 504, so that the control display 402 can be better protected.

[0040] like Figures 2 to 4 As shown, the gear box 3 includes a shell 302, which is formed by an upper shell and a lower shell fixedly connected. A second through hole 304 for the guide rod 7 to pass through and a first through hole 303 for the transmission rod 6 to pass through are opened on the shell 302. A linear bearing that cooperates with the guide rod 7 is installed in the second through hole 304. When the transmission rod 6 is a lead screw, a lead screw nut that cooperates with the lead screw is installed in the first through hole 303; when the transmission rod 6 is a circular rack, a linear bearing is installed in the first through hole 303.

[0041] Specifically, a power shaft 801, a transmission shaft 1 308 and a transmission shaft 2 309 are rotatably connected in the shell 302 through bearings, one end of the power shaft 801 passes through the shell 302 and is fixedly connected to the output end of the drill barrel driving mechanism 8, and the drill barrel driving mechanism 8 is preferably a motor, and a driving gear 802 is fixedly connected to the power shaft 801, and a driven gear 2 307 and a driven gear 1 306 meshing with the driving gear 802 are fixedly connected to the transmission shaft 1 308, one end of the transmission shaft 2 309 is rotatably connected to the shell 302, and the other end of the transmission shaft 2 309 is fixedly connected to a fixed cylinder 305, the bottom of the fixed cylinder 305 passes through the shell 302 and is rotatably connected to the shell 302, and a driven gear 3 310 meshing with the driven gear 2 307 is fixedly connected to the fixed cylinder 305. In this embodiment, the diameter of the driven gear three 310 is greater than the diameter of the driven gear one 306 , the diameter of the driven gear two 307 is greater than the diameter of the driving gear 802 , thereby achieving deceleration of the power of the drill tube driving mechanism 8 .

[0042] The drill barrel driving mechanism 8 is staggered with the fixed barrel 305, and the fixed barrel 305 is fixedly connected with the drill barrel body 2. The fixed barrel 305 and the second transmission shaft 309 are provided with a drill barrel center hole 3051, and the drill barrel center hole 3051 is coaxially arranged with the drill barrel body 2. The gear box 3 makes the drill barrel driving mechanism 8 staggered with the fixed barrel 305, and adds the drill barrel center hole 3051. When in use, the fixing rod 10 is passed through the drill barrel body 2, and the end of the fixing rod 10 is fixedly connected with the wall to be punched through the flange 1001, so that the whole machine can be fixed on the wall, and it is not necessary to manually hold or lift equipment to punch, which is more convenient to use; at the same time, in this way, the punching position can be determined more accurately, avoiding displacement during the punching process, and the flange 1001 and the fixing rod 10 are located inside the drill barrel body 2, and the part of the wall that is punched and fixed is the part that is drilled out later, so after the punching, there are no other fixed holes on the wall, thereby realizing a traceless punching operation.

[0043] like Figure 4As shown, the mobile drive mechanism 311 is preferably fixedly installed inside the housing 302, the transmission rod 6 is a circular rack, and the output end of the mobile drive mechanism 311 is fixedly connected with a pinion 312 for meshing with the transmission rod 6. When the mobile drive mechanism 311 is started, the mobile drive mechanism 311 drives the pinion 312 to mesh with the transmission rod 6, and then drives the gear box 3, the drill barrel drive mechanism 8, the drill barrel body 2 and the upper support plate 4 to move up and down, so that during the drilling process, the feeding of the drill barrel body 2 does not require manual force, which greatly reduces the labor intensity of drilling.

[0044] like Figures 6 to 10 As shown, the base 1 includes a base body, and the bottom of the base body is fixedly connected with a bottom plate 109 and a bottom plate 2 110, and the bottom plate 109 and the bottom plate 2 110 are used to seal and fix the bottom of the base body. The bottom plate 109 and the base body are jointly provided with a center hole 105 for the drill tube body 2 to pass through, and a first sealing ring 106 is provided in the center hole 105 of the base body to seal with the outer wall of the drill tube body 2, and the first sealing ring 106 prevents the sewage generated by the drill tube body 2 from splashing during the drilling process. A second sealing ring 111 is provided on the center hole 105 of the bottom plate 109, and the second sealing ring 111 is used to fit tightly with the wall surface to prevent the sewage generated by the drilling from flowing out and polluting the wall surface. The two sides of the base body are rotatably connected with sewage outlets 103 connected to the inside of the base body. When in use, the sewage outlet 103 is connected to the sewage pipe. The fixing rod 10 is a hollow structure. The fixing rod 10 is deep inside the drill barrel body 2 and is provided with a water outlet. The fixing rod 10 is connected to the water supply system. The water supply system is used to supply water to the inside of the drill barrel body 2. The drill barrel body 2 can be cooled during the drilling process and has a certain lubrication effect, thereby reducing the friction during the drilling process and improving the drilling efficiency. The sewage generated by drilling is discharged in time through the sewage outlet 103 and the sewage pipe to avoid it flowing out and polluting the wall.

[0045] A correction mechanism 9 is provided in the base body to cooperate with the outer wall of the drill barrel body 2. The correction mechanism 9 is preferably divided into two groups. The two groups of correction mechanisms 9 are respectively arranged on both sides of the center hole 105 and are symmetrically arranged. When drilling, the outer wall of the drill barrel body 2 is synchronously limited to prevent it from deflecting.

[0046] Specifically, the deviation correction mechanism 9 includes a positioning shaft 903, a rotating piece 1 901 and a rotating piece 2 902. The positioning shaft 903 is connected to the base body. One end of the rotating piece 1 901 and the rotating piece 2 902 are both rotatably connected to the positioning shaft 903. A nut is threadedly connected to the positioning shaft 903. The nut can limit the rotating piece 1 901 and the rotating piece 2 902 to prevent them from falling off the positioning shaft 903. The other ends of the rotating piece 1 901 and the rotating piece 2 902 are bent toward one side of the center hole 105, and the other ends of the rotating piece 1 901 and the rotating piece 2 902 are respectively rotatably connected with a deviation correction wheel 905. An elastic component 904 is provided between the rotating piece 1 901 and the rotating piece 2 902. The elastic component 904 is preferably a tension spring. The tension spring synchronously tightens the rotating piece 1 901 and the rotating piece 2 902, so that the deviation correction wheel 905 can always clamp the outer wall of the drill tube body 2 on both sides, thereby playing a deviation correction role.

[0047] In order to ensure the effectiveness of the deviation correction mechanism 9 and expand the opening range of the rotating piece 1 901 and the rotating piece 2 902, a limiting hole 108 is provided in the base body, and a limiting column for limiting the deviation correction mechanism 9 is fixedly connected in the limiting hole 108, and a limiting groove 906 corresponding to the limiting column is provided on the rotating piece 1 901 or the rotating piece 2 902. The limiting groove 906 expands the rotation range of the corresponding rotating piece, and at the same time, it can be limited, which is more reliable to use.

[0048] like Fig.10 As shown, a fixing hole 101 for auxiliary fixation of the whole machine is opened on the base 1. When the fixing rod 10 is inconvenient to use, the whole machine can be fixed through the fixing hole 101 in cooperation with the expansion bolt. The upper end surface of the fixing hole 101 is provided with a plurality of anti-slip grooves 1011. The anti-slip grooves 1011 can greatly improve the reliability of the expansion bolt fixation and avoid displacement, thereby ensuring the accuracy of the drilling position.

[0049] A vacuum suction cup 104 is fixedly connected to the bottom of the base 1, and the vacuum suction cup 104 is connected to the vacuum pump 505 through a pipeline. In this embodiment, the vacuum pump 505 is preferably fixedly installed on the fixed plate 503, and the guide rod 7 is a hollow structure. The pipeline passes through the guide rod 7 and is sealed and connected to the vacuum suction cup 104. For relatively smooth walls, the vacuum pump 505 can be started and the entire machine can be fixed to the wall through the vacuum suction cup 104.

[0050] One or both ends of the base 1 are rotatably connected with a detachable moving wheel 102. In this embodiment, the moving wheel 102 is installed at one end of the base 1. The moving wheel 102 facilitates the movement of the utility model, does not require manual handling, reduces labor intensity, and is more convenient to use.

[0051] Working principle:

[0052] The utility model is suitable for punching holes on both smooth and rough walls. Fig.12 As shown, when the moving wheel 102 is used, the fixing rod 10 is passed through the center hole 3051 of the drill tube, and a threaded hole can be directly opened at the bottom of the fixing rod 10, that is, a small hole is drilled on the wall at the position where a hole needs to be drilled, and fixed with an expansion bolt, and then the fixing rod 10 is threadedly connected with the expansion bolt, so that the whole machine is fixed to the wall by the support of the fixing rod 10. This situation is suitable for the case where the diameter of the drill tube body 2 is small, that is, the hole diameter of the wall hole is small.

[0053] When the required hole diameter is large, in order to improve the positioning accuracy and avoid displacement during the drilling process, the flange 1001 can be fixedly connected to the end of the fixing rod 10, that is, a plurality of small holes are drilled on the wall at the location where holes need to be drilled, and fixed with expansion bolts, and then the expansion bolts are fixed to the flange 1001. The flange 1001 increases the contact area with the wall, thereby improving the positioning accuracy and the stability of the fixation.

[0054] When drilling, the drill barrel driving mechanism 8 and the mobile driving mechanism 311 are started. The drill barrel driving mechanism 8 drives the drill barrel body 2 to rotate rapidly through the gear box 3. During the rotation of the drill barrel body 2, the mobile driving mechanism 311 drives the drill barrel body 2 to continuously move toward the wall surface, realizing automatic feeding during the drilling process until the wall surface is punched through. After the drilling is completed, the punched wall surface and the flange 1001 are retained in the drill barrel body 2. Since the drill barrel body 2 is trapped in the hole, the utility model will not fall off. After taking the utility model out of the hole, the drill rig is raised upwards, and the punched wall surface, the flange plate and the fixing rod 10 can be taken out from the drill barrel center hole 3051. At this time, there are no extra fixing holes on the wall surface after the drilling, realizing traceless drilling.

[0055] For non-smooth walls, the fixing holes 101 can be used to assist the fixing of the utility model, that is, small holes are drilled in the wall, and after fixing with expansion bolts, the expansion bolts pass through the fixing holes 101 and are fixedly connected to the base 1 through nuts and other fasteners, so that the whole machine is fixed to the wall, and the rotation of the whole machine can be avoided during the drilling process.

[0056] In addition, the smooth wall after decoration has a higher requirement for the cleanliness of the wall after drilling. Before drilling, the vacuum pump 505 can be started so that the vacuum suction cup 104 can be firmly attached to the wall. At this time, the second sealing ring 111 is tightly fitted with the wall, and the sewage outlet 103 is connected to the sewage collection mechanism through the sewage pipe. During the drilling process, the sewage can be prevented from flowing out and collected in the sewage collection mechanism to avoid contaminating the wall; at the same time, the whole machine can be prevented from rotating during the drilling process.

[0057] Finally, although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
