Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building construction technology, specifically relating to a drilling auxiliary device for avoiding metal. Background Technology
[0002] In engineering construction or renovation, drilling is a common operation in building structures or components such as beams, slabs, columns and walls using drilling equipment. However, metal objects such as steel bars and pipelines are often embedded inside buildings. If these metal objects are not removed during drilling, it will not only reduce drilling efficiency and damage the drilling equipment, but may also cause engineering safety hazards.
[0003] In existing technology, before drilling, a metal detector is used to detect the location of metal, which is then marked with a marking tool. Finally, the drilling equipment is operated to avoid the marked location. This process has the following drawbacks: 1. Frequent switching between metal detectors, marking tools, and drilling equipment is required, making the operation cumbersome and increasing the labor intensity of workers; 2. The use of multiple devices leads to high construction costs, and manual marking is prone to errors, affecting the accuracy of the work; 3. Poor process continuity severely reduces drilling efficiency.
[0004] Therefore, there is an urgent need for a device that can integrate metal detection and drilling functions, simplify operation, and reduce costs to address the shortcomings of existing technologies. Utility Model Content
[0005] This utility model aims to solve the problems of separation between metal detection and drilling operation in existing building drilling operations, frequent equipment switching, low efficiency and high cost, and provides a drilling auxiliary device that integrates metal detection positioning, dust prevention and noise reduction and convenient adaptation.
[0006] To achieve the above objectives, this utility model provides the following technical solution: A drilling aid for avoiding metal includes a housing made of flexible material. One end of the housing is provided with a connecting component for mounting the housing on a drilling device, so that the housing covers the drill bit of the drilling device. The housing is also provided with a sensing control component, which includes a power module, a sensing element, a control module, and a signal module that are electrically connected. The power module is used to provide power to the sensing element, the sensing element is used to detect the position of the metal object and send a signal to the control module, and the control module is used to receive the signal sent by the sensing element and control the signal module to issue an alarm prompt. The sensing element is installed at the end of the housing away from the connecting component.
[0007] To further enable the rapid disassembly of the drilling auxiliary device, the connecting assembly includes a connecting ring fixed to the end of the housing, a ball bearing fixed inside the connecting ring, and an annular magnet installed on the inner wall of the ball bearing through a fixing ring. The annular magnet can be attracted and fixed to the end face of the drill bit locking device of the drilling equipment, and the inner diameter of the annular magnet is larger than the diameter of the drill bit.
[0008] To further improve detection sensitivity and reduce costs, the housing is hollow inside and includes a small-diameter end and a large-diameter end. The small-diameter end is connected to the connecting assembly, and the large-diameter end is provided with a mounting ring. The sensing element is an induction coil assembly, which is installed inside the mounting ring of the housing. The induction coil assembly is connected to the power module through a power supply line located inside the housing.
[0009] To further improve ease of operation, safety, and efficiency, the power module includes a power port and a switch. The power port is used to connect to a power source, and the switch is used to turn the circuit between the power module and the sensing element on or off. The signal module includes a buzzer indicator light. When the sensing element detects a metal object, the buzzer indicator light illuminates and an alarm sound is emitted. The power port, switch, and buzzer indicator light are all mounted on the connecting ring.
[0010] Furthermore, the power module and control module are arranged in a ring on the connecting ring, and there are gaps between the power module, control module and ball bearing and ring magnet.
[0011] To further avoid the impact of the casing on drilling operations, the casing is provided with multiple continuous bends.
[0012] The working principle of this utility model is as follows: When the induction coil group is energized, it generates an electromagnetic signal. When there is a metal part in the annular area enclosed by the induction coil group, the metal will reflect the electromagnetic signal. After the control module receives the electromagnetic signal, the buzzer indicator of the control signal module lights up and emits an alarm sound, thereby determining whether there is a metal part inside the building and locating the position of the metal part.
[0013] Compared with the prior art, the present invention has the following beneficial technical effects: This utility model can be used with drilling equipment through the connecting component, which can integrate metal detection and drilling functions to realize integrated detection-drilling operation. This allows workers to operate without switching equipment, simplifying the operation process and greatly improving work efficiency. This utility model has a simple structure and low cost. It can be adapted to the drill bit locking device of common drilling equipment through the ring magnet, without the need to modify existing equipment, and has a wide range of applications. The flexible shell of this invention is always placed over the drill bit during the drilling process, which not only reduces noise but also collects construction debris and prevents dust from flying, effectively reducing construction pollution and improving the working environment. This invention provides intuitive feedback on the position of the metal by setting a buzzer indicator light, eliminating the need for manual marking, effectively reducing the difficulty of operation, and improving the accuracy and convenience of the work.

Detailed Implementation
[0015] The following detailed description illustrates the specific implementation method: Example
[0016] like Figure 1 and 2 As shown, a drilling auxiliary device for avoiding metal includes a housing 1 made of flexible rubber material. The housing 1 is hollow and has multiple continuous bends. One end of the housing 1 is a small-diameter end, and a connecting component 2 is fixed on the small-diameter end. The connecting component 2 is used to install the housing 1 on a drilling device 4, so that the housing 1 covers the outside of the drill bit 42 of the drilling device 4. The other end of the housing 1 is a large-diameter end, and a mounting ring 11 is formed on the large-diameter end.
[0017] like Figure 2-4 As shown, the connecting assembly 2 includes a connecting ring 21 fixed to the small diameter end of the housing 1. A ball bearing 22 is fixed to the inner wall of the connecting ring 21. An annular magnet 24 is installed on the inner wall of the ball bearing 22 through a fixing ring 23. The annular magnet 24 can be attracted and fixed to the end face of the drill bit locking device 41 of the drilling equipment 4. The inner diameter of the annular magnet 24 is larger than the diameter of the drill bit 42.
[0018] like Figure 1-4As shown, the housing 1 is also provided with a sensing control assembly 3, which includes a power module, a sensing element, a control module, and a signal module that are electrically connected. The power module and the control module are arranged in a ring on the connecting ring 21, and there are gaps between the power module, the control module, the ball bearing 22, and the ring magnet 24. The power module is used to provide power to the sensing element, the sensing element is used to detect the position of the metal part and send a signal to the control module, and the control module is used to receive the signal sent by the sensing element and control the signal module to issue an alarm prompt. The sensing element adopts an induction coil group 31, which is installed in the mounting ring 11 of the housing 1. The current is transmitted between the induction coil group 31 and the power module through a power supply line 32, which is located inside the housing 1. The power module includes a power port 33 and a switch 34. The power port 33 is used to connect the power supply, and the switch 34 is used to turn the circuit between the power module and the sensing element on or off. The signal module includes a buzzer indicator 35. The power port 33, the switch 34, and the buzzer indicator 35 are all installed on the connecting ring 21.
[0019] When switch 34 is turned on, power is supplied to the induction coil group 31 through the power module. After the induction coil group 31 is powered on, it generates an electromagnetic signal. When there is a metal part in the annular area enclosed by the induction coil group 31, the metal will reflect the electromagnetic signal. After the control module receives the electromagnetic signal, the buzzer indicator 35 of the control signal module lights up and emits an alarm sound, thereby determining whether there is a metal part inside the building and locating the position of the metal part.
[0020] The specific working process of this utility model is as follows: 1. Installation (e.g.) Figure 4 (As shown) 1.1 Turn on switch 34 to supply power to the induction coil group 31. Bring the mounting ring 11 at the front end of housing 1 close to metal (such as drill bit 42 of drilling equipment 4) to test the function. After confirming that the buzzer indicator 35 responds normally, turn off switch 34. 1.2 Lock the drill bit 42 onto the drilling equipment 4 using the drill bit locking device 41; 1.3 Pass the drill bit 42 through the center of the annular magnet 24, align the annular magnet 24 with the drill bit locking device 41, and fix the drilling auxiliary device and the drilling equipment 4 by magnetic force; 1.4 Rotate housing 1 to check connection reliability and ensure that ball bearing 22 can rotate normally relative to each other (during drilling, the annular magnet 24 and the inner ring of ball bearing 22 rotate with the drill bit 42, while housing 1 and the outer ring of bearing remain stationary).
[0021] 2. Metal detection positioning 2.1 Turn on switch 34, hold the drilling equipment 4 and move the induction coil group 31 of housing 1 to the area of the building to be drilled; 2.2 Observe the buzzer indicator 35: If the buzzer indicator 35 is lit and emits a sound, it indicates that there is metal in the area and drilling is not advisable. The drilling position needs to be adjusted. Otherwise, there is no metal and drilling can proceed.
[0022] 3. Drilling operations For areas without metal, the drilling equipment 4 is started and applied in the positive direction. The housing 1 adheres to the building surface under pressure to prevent dust from spreading and reduce noise. The construction debris generated during drilling is collected inside the housing 1.
[0023] 4. Disassembly 4.1 After drilling is completed, turn off switch 34; 4.2 Dump the construction debris inside shell 1; 4.3 Manually separate the annular magnet 24 from the drill bit locking device 41 and remove the drilling auxiliary device.
[0024] This invention integrates metal detection and drilling functions, eliminating the need for frequent equipment switching during drilling operations, thus simplifying the process and improving efficiency. It also features a simple structure, low cost, compatibility with common drilling equipment, and a wide range of applications. The flexible shell combines dustproof, noise reduction, and debris collection functions, improving the working environment. Furthermore, the buzzer indicator light provides intuitive feedback on the metal location, eliminating the need for manual marking, reducing operational difficulty, and improving accuracy.
