Abstract
Description
Technical Field
[0001] The present application relates to the technical field of construction equipment, and in particular to a ceiling drilling auxiliary tool operated by a single person on the ground. Background Art
[0002] Currently, when drilling holes on indoor ceilings, construction workers usually stand on top of a ladder and use a handheld impact drill to drill holes. This method not only causes the drilling dust to fly freely, causing dust pollution to the construction environment; secondly, when construction workers stand on top of a ladder and use a heavy impact drill to drill holes, they need to apply a certain amount of force, and the force is mutual, which may cause the construction workers to shake and fall off the ladder, thus causing safety accidents.
[0003] In the prior art, a high-altitude mobile top plate hole-turning device is disclosed (authorization announcement number: CN204470652U). The device is provided with an operating bracket, a cable tie is used to tie the impact drill on the top of the bracket, and a dust collector is provided on the drill head of the impact drill to collect dust, thereby enabling the operator to drill holes on the top surface and collect dust on the ground. However, the device uses cable ties to tie the impact drill, and the impact drill will generate large vibrations during operation. The cable tie tying method may cause the impact drill to move or loosen. When drilling more holes, the impact drill may need to be frequently re-fixed. Secondly, a bellows is provided in the middle of the chip collector. After repeated use, the bellows may be compressed and deformed and cannot be restored to its original position. If the bellows cannot be reset, chips may fly out from the gap between the chip collector and the top surface when drilling. Utility Model Content

DETAILED DESCRIPTION
[0017] The present application will be described in detail below with reference to the exemplary embodiments in the accompanying drawings. However, it should be understood that the present application can be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. These embodiments are provided here to make the disclosure of the present application more complete and to fully convey the concept of the present application to those skilled in the art.
[0018] In the description of the present application, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the scope of protection of the present application.
[0019] The inventors of the prior art have the defects that the impact drill may become loose and dust may fly out easily during operation. After careful analysis, they found that the main reason for the above problems is that the current way to fix the impact drill is generally to use cable ties for binding. When drilling, the drill bit of the impact drill applies force upward, and the surface of the hole will also give the impact drill a reaction force. Secondly, the impact drill is in a state of vibration during the drilling process. When both the reaction force and vibration exist, the impact drill may become loose, the stability will deteriorate, and the drilling work will be affected. Secondly, in the scheme disclosed in the prior art, a dust collector is designed at the drill bit. The middle part of the collector is a bellows structure. The working principle is that when the drill bit moves upward, the top of the dust collector contacts the surface of the hole. As the drill bit moves upward, the dust collector is compressed, the drill bit moves downward, and the dust collector recovers. However, the bellows is a plastic structure. After drilling many times, the bellows deforms and may not be able to reset itself. At this time, the top of the dust collector becomes lower and lower, resulting in the top surface of the dust collector not being able to contact the drilling surface at the beginning of drilling, which eventually causes dust to fly. Based on the above analysis, the inventors improved the structure of the drilling tool.
[0020] Combination Figure 1 and Figure 2 As shown, in one embodiment of a single-person ground-operated ceiling drilling auxiliary tool of the present application, the tool includes a lifting frame that drives the impact drill 11 to move up and down, and the structure of the lifting frame includes a first support rod 1, a handrail 2, a connecting rod 3 and a second support rod 8. The middle part of the first support rod 1 is hinged to the middle part of the handrail 2, the top of the first support rod 1 is hinged to one end of the connecting rod 3, the bottom of the second support rod 8 is hinged to the right end of the handrail 2, and the middle part is hinged to one end of the connecting rod 3. When the handrail 2 swings counterclockwise, the second support rod 8 moves upward, and vice versa. The bottom of the first support rod 1 is connected to a base 9, and the bottom of the base 9 is provided with wheels 10, and the tool can be transported by the wheels 10 and the brake pads of the wheels 10 can be used to limit the movement of the wheels 10 to perform top surface drilling work.
[0021] The tool also includes a bracket 5 for placing and fixing the impact drill 11, and a dust collection hood 4 for collecting dust; the bracket 5 is bolted to the top side wall of the second support rod 8 of the lifting frame, and the width of the bracket 5 is greater than the second support rod 8. The front and rear end faces of the bracket 5 are respectively provided with a pressure plate assembly 6 to prevent the impact drill 11 from moving forward and backward, and the left side of the bracket 5 is provided with a fixed hook strip 13 to prevent the impact drill 11 from moving horizontally; the dust collection hood 4 is installed on the top of the lifting frame by bolts, and the dust collection hood 4 includes a bottom plate 41, and a retractable cover body is provided on the bottom plate 41, and a spray head 44 and a suction head 42 are provided on the cover body, and the exposed end of the spray head 44 is connected to the water pipe, and the exposed end of the suction head 42 is connected to the negative pressure air source; the bottom plate 41 is provided with an elastic component to guide the cover body to restore after being compressed. When in use, place the impact drill 11 on the bracket 5, and then use the pressure plate assembly 6 and the fixing hook strip 13 to fix the impact drill 11 on the bracket 5. The lifting frame lifts the bracket 5 to the top surface of the hole to be drilled. When drilling, the drill bit rises and contacts the top surface. In the early stage of drilling, the top surface of the dust collection hood 4 contacts the top surface of the drilled hole to cover the drill bit. When the drill bit continues to rise, the dust collection hood 4 is compressed, and the bellows 47 in the middle section is compressed and deformed. At this time, the spray head 44 sprays water mist to settle the dust and reduce dust flying. The negative pressure of the suction head 42 sucks away the dust. After the drilling is completed, the lifting frame descends, and the dust collection hood 4 is reset by the elastic component.
[0022] In order to facilitate the placement of the impact drill 11, the bracket 5 body is a cavity, and its top and right end are open. The impact drill 11 can be placed from top to bottom or from the side.
[0023] In order to facilitate the fixing of the impact drill 11, refer to Figure 1 and Figure 3 , through holes are respectively opened on both sides of the bracket 5, and a threaded sleeve 14 is welded on the end surface of the through hole. The pressure plate assembly 6 includes a screw 61, a pressure plate 62 and a handle 63. The screw 61 is arranged in the threaded sleeve 14 and extends into the bracket 5; the pressure plate 62 is arranged at one end of the screw 61 extending into the bracket 5. The main body of the pressure plate 62 is a metal plate, and a rubber layer is provided on its end surface. When the pressure plate 62 contacts the impact drill 11, the rubber layer is deformed and wraps part of the surface of the impact drill 11, increasing the pressure and friction, thereby limiting the impact drill 11 from moving forward or backward or shaking; the handle 63 is arranged at the other end of the screw 61, and the handle 63 is a metal block with a through hole on the end surface. An extension rod can be inserted into the through hole to facilitate rotation to tighten the screw 61.
[0024] The function of the fixed hook strip 13 is to limit the lateral movement or shaking of the impact drill 11. Figure 3As shown, the fixing hook strip 13 is an L-shaped structure, which is divided into a long rod and a short rod, and the long rod is provided with a thread; a through hole is provided on the left side of the bracket 5, and the long rod of the fixing hook strip 13 is arranged in the through hole, and a nut 12 is provided on the long rod, and the short rod is located in the bracket 5 to prevent the impact drill 11 from being tightly inserted into the bracket 5, and the short rod is downward, and the direction of the short rod is as shown in FIG. Figure 3 As shown, the long rod of the fixed hook strip 13 is then moved to the left, so that the short rod contacts the impact drill 11, and then the nut 12 on the long rod is tightened, so that the fixed hook strip 13 cannot move left or right (that is, when the fixed hook strip 13 moves to the left, it is restricted by the impact drill 11, and when it moves to the right, it is restricted by the nut 12), thereby fixing the impact drill 11 to move left or right or shake. Among them, the fixed hook strip 13 is at least two places.
[0025] As mentioned above, the middle part of the cover body is a bellows 47, and the bottom and top surfaces of the bellows 47 are respectively bonded with hard plastic tubes 46, such as PVC tubes, and the top surface of the hard plastic tube 46 at the top of the bellows 47 is provided with a flange surface 45; the spray head 44 is connected to the side of the hard plastic tube 46 at the top of the bellows 47, and the suction head 42 is connected to the hard plastic tube 46 at the bottom of the bellows 47.
[0026] The spray head 44 is an atomizing nozzle, and the suction head 42 body is a plastic tube, and a sealing nut connected to the negative pressure tube is provided at the exposed end.
[0027] The elastic component is used to guide the hood to reset. The elastic component includes a guide rod 48 and a spring 43. A coaxial through hole is provided on the bottom plate 41 and the flange surface 45 of the hard plastic tube 46 at the top of the bellows 47. A guide rod 48 is provided in the coaxial through hole. The top surface of the guide rod 48 is provided with a flange to prevent it from escaping from the flange surface 45. The bottom of the guide rod 48 is provided with a thread, and a nut 12 is screwed on the thread. The spring 43 is sleeved on the guide rod 48 and is located between the bottom plate 41 and the flange surface 45. When the dust collection hood 4 is pressurized, the guide rod 48 moves downward and the spring 43 is pressurized. After the pressure of the dust collection hood 4 disappears, the reaction force of the spring 43 pushes the flange surface 45 provided on the top surface of the hard plastic tube 46 at the top of the bellows 47 upward, and the flange surface 45 drives the guide rod 48 to reset.
[0028] A diagonally braced reinforcing rib 7 is bolted to the side wall of the second support rod 8 and the bottom of the bracket 5 to improve the fixing strength of the bracket 5 .
[0029] When using the auxiliary tool, install the impact drill 11 on the bracket 5, lock the pressure plate assembly 6 and the fixed hook strip 13, and install the dust collection cover 4 on the top of the second support rod 8 of the lifting frame, wherein the through hole of the bottom plate 41 is sleeved on the drill bit, and then move the auxiliary tool to the specified position through the wheel 10. After locking the wheel 10, press the handrail 2 downward, the second support rod 8 will move upward, driving the drill bit to move upward. After the drill bit contacts the surface to be drilled, it is the initial stage of drilling. After the drill bit enters the drilling surface, the corrugation of the dust collection cover 4 The top flange surface 45 of the hard plastic tube 46 above the tube 47 contacts the surface of the drill hole, covering the drilled dust. Then, during the drilling process, the spray head 44 connected to the water source sprays water mist to settle the dust. Most of the settled dust is sucked away by the negative pressure of the suction head 42, reducing the dust residue in the cover. In the later stage of drilling, the drill bit penetrates into the surface of the drill hole. At this time, the bellows 47 in the middle section of the cover body has been compressed. When the drill bit is moved down, the cover body regularly moves the flange surface 45 through the reaction force of the spring 43 of the elastic component, thereby restoring the cover body. Then, the second drilling can be performed.
[0030] It should be understood that all the above embodiments are illustrative rather than restrictive, and various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of the present application should be within the protection scope of the present application.
