Description

Technical Field

[0001] The utility model relates to the technical field of punching dustproof accessories, in particular to a steel component punching dustproof device. Background Art

[0002] Steel components are an indispensable and important part of modern buildings. In modern society, with the advancement of science and technology and the development of construction technology, steel components are used more and more widely in construction projects. They not only bear the weight of the building, but also transmit various forces to ensure the stability and safety of the building. Bolts are usually used to connect steel components, which requires drilling holes on the outer surface of the steel components.

[0003] At present, there are many types of equipment for drilling holes in steel components. For example, drilling machines with a high degree of automation are suitable for smaller steel components, which can be easily loaded onto the machine. However, large steel components are usually not convenient to be transported to the machine for drilling, so manual handheld drills are often used for drilling. This type of drill does not have a dustproof function, which causes iron chips to splash during the drilling process, which can easily cause harm to the staff. To this end, we propose a steel component drilling dustproof device to solve the above problem. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the utility model provides a dust-proof device for drilling holes in steel components, which is suitable for small drilling rigs and can automatically collect iron filings when drilling holes in steel components to prevent flying iron filings from causing harm to workers, thereby solving the above-mentioned technical problems.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a steel component drilling dust-proof device, comprising a motor, the output end of the motor is connected to a coupling, a drill bit is clamped in the coupling, a dust cover is connected to the outer shell of the motor by screws, the outer surface of the dust cover is fixedly connected to a delivery pipe, one end of the delivery pipe is fixedly connected to a collection box, the top surface of the collection box is fixedly connected to a round tube, the suction port of a suction pump is inserted in the round tube, a clamp is installed on the outer surface of the suction pump, the outer surface of the clamp is fixedly connected to a block, a rack is fixedly connected to the outer shell of the motor, sliding grooves are provided on both sides of the rack, the rack is meshed and connected to a transmission wheel, the transmission wheel is transmission-connected to a worm, and a shell is provided on the outer surface of the transmission wheel, the outer surface of the shell is fixedly connected to a slider, and the outer surface of the shell is rotatably connected to a handle.

[0008] Preferably, one end of the worm is fixedly connected to a rotating rod, and one end of the rotating rod is fixedly connected to a turning handle.

[0009] Through the above technical solution, the drill bit can be driven to rotate by starting the motor in conjunction with the coupling. At this time, the drill bit is aimed at the position where a hole needs to be drilled on the steel structure. Then, the handle is turned clockwise to drive the turning rod, the turning rod drives the worm to rotate, and the worm drives the transmission wheel to rotate. The transmission wheel drives the rack to move downward, and the rack drives the motor to move downward, so that the drill bit drills holes in the steel structure. After drilling, the handle is turned counterclockwise to reset the motor.

[0010] Preferably, a sliding block is slidably connected in the sliding groove, and a rectangular groove is provided on one side of the housing close to the rack.

[0011] Through the above technical solution, when the transmission wheel drives the rack to rise and fall, the slider moves in the slide groove, and the slider cooperates with the slide groove to limit and guide the rack. Since there is a self-locking structure between the worm and the transmission wheel, the motor and other components will not fall automatically.

[0012] Preferably, the dust cover is made of transparent plastic material, and the main body of the dust cover is a telescopic hose.

[0013] Through the above technical solution, when drilling a steel component, the bottom of the dust cover is in contact with the outer surface of the steel component, so that the debris generated during drilling will not splash everywhere, and because the dust cover is made of transparent plastic material, the drill bit inside can be easily viewed. During the drilling process, the drill bit continuously moves downward, and the dust cover can also be compressed to remain tightly attached to the outer surface of the steel component.

[0014] Preferably, the bottom of the shell is fixedly connected to the support rod, the bottom of the support rod is fixedly connected to the base, and the outer surface of the support rod is connected to the block by bolts.

[0015] Through the above technical solution, the base contacts the outer surface of the steel structure during operation, and the support rod supports the shell and other components. During the drilling process, a negative pressure is generated inside the collection box by starting the suction pump, and a negative pressure is also generated inside the dust cover through the conduction of the conveying pipe. In this way, the iron filings are sucked into the collection box for temporary storage. The overall structure avoids the generation of dust and iron filings during drilling.

[0016] Preferably, the inner thread of the base is connected to a pin rod, the top of the pin rod contacts the collection box, and the bottom of the pin rod is fixedly connected to a twist knob.

[0017] Through the above technical solution, filter cotton is arranged inside the suction end of the suction pump, which can prevent dust and iron filings from entering the interior of the suction pump. When the dust and iron filings in the collection box are saturated, the pin rod can be moved downward by rotating the twist in the opposite direction. At this time, the collection box descends under the action of gravity and separates from the suction end of the suction pump. In this way, the collection box can be removed and the dust and iron filings collected inside can be poured out.

[0018] Compared with the prior art, the utility model provides a steel member punching dust prevention device, which has the following beneficial effects:

[0019] 1. The utility model provides a dust cover and other components. During the drilling process, the bottom of the dust cover contacts the outer surface of the steel member to prevent iron chips from splashing. By starting the suction pump, negative pressure is generated inside the collection box. Through the conduction of the conveying pipe, negative pressure is also generated inside the dust cover. In this way, the iron chips are sucked into the collection box for temporary storage. The overall structure avoids the generation of dust and iron chips during drilling.

[0020] 2. The utility model can drive the drill bit to rotate by starting the motor in conjunction with the coupling. At this time, the drill bit is aimed at the position where a hole needs to be drilled on the steel structure. Then, the handle is turned clockwise to drive the rotating rod, the rotating rod drives the worm to rotate, and the worm drives the transmission wheel to rotate. The transmission wheel drives the rack to move downward, and the rack drives the motor to move downward, so that the drill bit drills holes in the steel structure. After drilling, the handle is turned counterclockwise to reset the motor. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Specifically, one end of the worm 14 is fixedly connected to the rotating rod 18, and one end of the rotating rod 18 is fixedly connected to the turning handle 17. The advantage is that the drill bit 3 can be driven to rotate by starting the motor 1 in cooperation with the coupling 2. At this time, the drill bit 3 is aligned with the position where the steel structure needs to be drilled, and then the turning handle 17 is turned clockwise to drive the rotating rod 18, and the rotating rod 18 drives the worm 14 to rotate, and the worm 14 drives the transmission wheel 13 to rotate, and the transmission wheel 13 drives the rack 11 to move downward, and the rack 11 drives the motor 1 to move downward, so that the drill bit 3 drills holes in the steel member, and after the drilling is completed, the turning handle 17 is turned counterclockwise to reset the motor 1.

[0030] Specifically, the slide block 16 is slidably connected in the slide groove 12, and a rectangular groove is provided on one side of the housing 15 close to the rack 11. The advantage is that when the transmission wheel 13 drives the rack 11 to rise and fall, the slide block 16 moves in the slide groove 12, and the slide block 16 cooperates with the slide groove 12 to limit and guide the rack 11. Since there is a self-locking structure between the worm 14 and the transmission wheel 13, the motor 1 and other components will not fall automatically.

[0031] Specifically, the dust cover 4 is made of transparent plastic material, and the main body of the dust cover 4 is a telescopic hose. The advantage is that when drilling a steel member, the bottom of the dust cover 4 abuts against the outer surface of the steel member, so that the debris generated during drilling will not splash everywhere, and because the dust cover 4 is made of transparent plastic material, the drill bit 3 inside can be easily viewed, and the drill bit 3 continuously moves downward during the drilling process, and the dust cover 4 can also be compressed to keep close to the outer surface of the steel member.

The advantage is that a filter cotton is arranged inside the suction end of the suction pump 8, which can prevent dust and iron filings from entering the suction pump 8. When the dust and iron filings in the collection box 6 are saturated, the pin rod 21 can be moved downward by rotating the twist 22 in the opposite direction. At this time, the collection box 6 descends under the action of gravity and separates from the suction end of the suction pump 8, so that the collection box 6 can be removed to pour out the dust and iron filings collected inside.

[0034] When in use, first align the drill bit 3 with the position where a hole is required on the steel structure, then start the motor 1, and rotate the handle 17 clockwise to drive the rotating rod 18, and the rotating rod 18 drives the worm 14 to rotate, and the worm 14 drives the transmission wheel 13 to rotate, and the transmission wheel 13 drives the rack 11 to move downward, and the rack 11 drives the motor 1 to move downward, so that the drill bit 3 drills a hole in the steel member. Since the bottom of the dust cover 4 abuts against the outer surface of the steel member, the debris generated during drilling will not splash everywhere. By starting the suction pump 8, a negative pressure is generated inside the collection box 6, and a negative pressure is also generated inside the dust cover 4 through the conduction of the conveying pipe 5, so that the iron filings are sucked into the collection box 6 for temporary storage, and the overall structure avoids dust and iron filings generated during drilling. When the dust and iron filings in the collection box 6 are saturated, the pin 21 can be moved downward by rotating the knob 22 in the opposite direction. At this time, the collection box 6 descends under the action of gravity and separates from the suction end of the suction pump 8, so that the collection box 6 can be removed to pour out the dust and iron filings collected inside.
