[0037] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0038] This application provides a rebar drilling device.

[0039] Example 1, such as Figures 1-6 As shown.

[0040] A rebar drilling device, including a mobile frame 1.

[0041] Furthermore, the mobile frame 1 includes a frame body 101, casters 102, and handrails 103. The frame body 101 is a cuboid frame structure. The casters 102 are installed at each corner of the bottom surface of the frame body 101, and the handrails 103 are installed on the rear side of the frame body 101.

[0042] The device is moved to the drilling position using the movable frame 1 for drilling operations. During movement, the worker can easily push the device by holding the handle 103. The casters 102 are preferably casters with brakes, and are preferably casters from Shanghai Bidi Industrial Aluminum Profile Accessories Co., Ltd., model CE-W75D-12C. This model of caster 102 has a braking function, making it more convenient to use.

[0043] It also includes a drilling device 2, which is installed inside the movable frame 1 to complete the drilling operation.

[0044] Further, the drilling device 2 includes a front top plate 201, a rear top plate 202, a lifting push rod 203, a positioning rod 204, a positioning wheel 205, a support wheel 206, a connecting belt 207, a positioning frame 208, a lifting plate 209, a drilling motor 210, and a drill bit 211. The front top plate 201 and the rear top plate 202 are arranged on the top of the movable frame 1. The drilling motor 210 is installed on the bottom surface of the front top plate 201. The positioning rod 204 is arranged at the output end of the drilling motor 210. The two ends of the positioning rod 204 are rotatably connected to the positioning wheel 205. 5. The support wheel 206 is rotatably connected to the top front side of the movable frame 1. A pair of positioning frames 208 are provided on the front side of the movable frame 1. The lifting plate 209 is slidably connected between the two positioning frames 208. The drilling motor 210 is installed on the lifting plate 209. The drill bit 211 is installed at the output end of the drilling motor 210. The connecting belt 207 is provided on the bottom surface of the rear top plate 202. The connecting belt 207 passes around the outer side of the positioning wheel 205 and the support wheel 206 in sequence, and its other end is fixedly connected to the lifting plate 209.

[0045] The drilling motor 210 drives the drill bit 211 to rotate, performing drilling operations. The output end of the lifting push rod 203 drives the positioning rod 204, which, through the positioning wheel 205, lifts the connecting belt 207, thereby causing the lifting plate 209 at the other end of the connecting belt 207 to move up and down, performing drilling operations to control the drilling depth. When the output end of the lifting push rod 203 retracts, the lifting plate 209 descends, and the drill bit 211 descends; when the output end of the lifting push rod 203 extends, the lifting plate 209 rises, and the drill bit 211 rises.

[0046] The drill bit 211 has a variable diameter. The variable diameter of the drill bit 211 allows for drilling holes of various sizes to meet the needs of rebar installation.

[0047] The drill bit 211 includes a connecting rod 2111, a central shaft 2112, an outer sleeve 2113, a sliding shaft 2114, a lever sleeve 2115, a telescopic slider 2116, a cutting body 2117, and a fixing bolt 2118. The output shaft of the drilling motor is connected to the connecting rod 2111. The central shaft 2112 is located at the bottom end of the connecting rod 2111. The outer sleeve 2113 is located at the bottom end of the central shaft 2112. The upper part of the central shaft 2112 is threaded and screwed to the lever sleeve 2115. The bottom end of the lever sleeve 2115 is rotatably connected to the sliding shaft 2114. The outer wall of the sliding shaft 2114 is tapered. The outer sleeve 2113 has several telescopic grooves extending through its sidewall. A telescopic slider 2116 is slidably connected within each groove. A blade 2117 is mounted on the outer side of the telescopic slider 2116. The inner side of the telescopic slider 2116 is inclined, and a drive groove is formed on its inner surface. A drive slider is located on the outer side of the sliding shaft 2114, and is slidably connected to the drive groove. The drive slider is a T-shaped slider. The drive slider moves up and down along the drive groove, thereby allowing the sliding shaft 2114 to push or pull the telescopic slider 2116, extending it outwards or inwards. A threaded hole extends through the top wall of the telescopic groove to the top of the sidewall of the outer sleeve 2113. A fixing bolt 2118 is screwed into the threaded hole, with its bottom end contacting the telescopic slider 2116, thus fixing the position of the telescopic slider 2116.

[0048] The outer side of the lever sleeve 2115 is provided with a scale, which can be used to distinguish the diameter of the drill bit 211.

[0049] When the diameter of the drill bit 211 needs to be adjusted, several fixing bolts 2118 are unscrewed and removed. Then, the wrench is used to rotate the actuating sleeve 2115, causing the sliding shaft 2114 to move upward or downward. This, in turn, through the cooperation of the telescopic slider 2116 and the telescopic groove, pushes or pulls the telescopic slider 2116 outward or inward, thereby changing the diameter of the drill bit 211. After adjustment, the fixing bolts 2118 are screwed back in to fix the position of the telescopic slider 2116.

[0050] Furthermore, a movable component 3 is installed within the drilling device 2 to adjust the drilling position of the drilling device 2. The movable component 3 is used to adjust the position of the drill bit 211, thereby adjusting the position of the drill bit 211.

[0051] Furthermore, the moving component 3 includes an ear plate 301, a rotating roller 302, a transmission belt 303, and a moving motor 304. A lifting groove 2091 is provided through the middle of the lifting plate 209. A set of ear plates 301 are respectively provided on both sides of the lifting groove 2091. The rotating roller 302 is rotatably connected between the ear plates 301. The transmission belt 303 is wrapped between the two rotating rollers 302. The drilling motor 210 is installed on the transmission belt 303 near the lifting groove 2091. The moving motor 304 is installed on the outside of the ear plate 301. The output shaft of the moving motor 304 is fixedly connected to any of the rotating rollers 302.

[0052] The mobile motor 304 operates, driving the rotating roller 302 to rotate, which in turn drives the transmission belt 303 covering its outer side to move, ultimately causing the drilling motor 210 to move its position to the left or right.

[0053] It also includes a hole cleaning device 4, which is installed on the front side of the drilling device 2 to clean the drilled holes.

[0054] Furthermore, the hole cleaning device 4 includes a limiting plate 401, a top rod 402, a sliding rod 403, a cleaning roller 404, and a pressing handle 405. The limiting plate 401 is disposed on the front side of the positioning frame 208. The limiting plate 401 has several sliding holes 4011 extending through it. The sliding rod 403 is slidably connected within the sliding holes 4011. The cleaning roller 404 is installed at the bottom end of the sliding rod 403. The top rod 402 is disposed at the top end of the sliding rod 403. The pressing handle 405 is disposed at the top end of the top rod 402. Several cleaning rollers 404 are provided, with their diameters increasing sequentially, each corresponding to a hole of a different diameter. By holding the pressing handle 405, the cleaning roller 404 is inserted into the pre-drilled hole and moved up and down to clean the pre-drilled hole.

[0055] Furthermore, a barrier plate 406 is provided on the front side of the limiting plate 401, and an extension groove 4061 is provided through the surface of the barrier plate 406, which is located directly below the cleaning roller 404.

[0056] The cleaning roller 404 is located above the barrier plate 406. When the pressing handle 405 is pressed, the cleaning roller 404 will squeeze through the protrusion groove 4061 and then extend into the hole of the drilled hole for cleaning. After completion, the cleaning roller 404 is pulled out above the barrier plate 406.

[0057] The hole cleaning device 4 is equipped with a blower device 5 to further clean the drilled holes.

[0058] Furthermore, the blowing device 5 includes a filter box 501, a blowing fan 502, and a back suction fan 503. The filter box 501 is disposed on the front side of the limiting plate 401, and the blowing fan 502 and the back suction fan 503 are installed on the outside of the filter box 501.

[0059] The top rod 402 has an inlet hole 4021 and an outlet hole 4022. The inlet hole 4021 passes through the sliding rod 403 and the cleaning roller 404 in sequence. The bottom end of the cleaning roller 404 has a blowing hole 4023, which is connected to the inlet hole 4021. The inlet hole 4021 passes through the sliding rod 403 and the cleaning roller 404 in sequence. The side wall of the cleaning roller 404 has a plurality of suction holes 4024, which are connected to the outlet hole 4022.

[0060] The output end of the blower 502 is connected to the inlet hole 4021 via a pipe, the input end of the back suction fan 503 is connected to the outlet hole 4022 via a pipe, and the output end of the back suction fan 503 is connected to the inner cavity of the filter box 501 via a pipe.

[0061] When the cleaning roller 404 extends into the drilled hole for cleaning, the blower 502 and the suction fan 503 are started. The blower 502 introduces air into the inlet hole 4021 and blows it out through the blower hole 4023 to blow air into the hole. The suction fan 503 sucks out the air from the outlet hole 4022, making the outlet hole 4022 a negative pressure state. The debris and dust blown up from the drilled hole are sucked into the outlet hole 4022 through the suction hole 4024 and discharged. The suction fan 503 then guides it into the filter box 501.

[0062] An electrical box is installed inside the mobile frame 1, and a controller is installed inside the electrical box. The controller is connected to each electrical component via circuits.

[0063] When using this invention:

[0064] The process of installing rebar involves drilling, cleaning the holes, blowing the holes, curing, installing the rebar, and injecting adhesive.

[0065] When drilling, push the device to the position to be drilled, start the drilling motor, and then start the lifting push rod to adjust the height of the drill bit and control the drilling depth.

[0066] After drilling is complete, begin the hole cleaning operation. Adjust the position of the equipment and align the cleaning roller with the drilled hole. Press the pressing handle to insert the cleaning roller into the drilled hole and move it up and down to clean the hole.

[0067] At the same time, the blower and the suction fan are started to blow the holes while cleaning them.

[0068] The hole cleaning is now complete, and the subsequent rebar installation can proceed.
