Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to an obstacle-avoiding punching device for planting reinforcement bars. Background Art

[0002] In the field of construction, with the continuous changes in building functional requirements, the increase in service life and the continuous development of construction technology, the renovation and reinforcement of existing building structures have become common needs; in past construction engineering practices, when faced with changes in building structural systems, spatial layout adjustments or structural damage repairs, traditional connection methods are often difficult to meet the requirements of high efficiency, reliability and less damage to the original structure; at the same time, in some building repair projects where the structure is partially damaged due to natural disasters or long-term use, a method is needed that can accurately locate and effectively strengthen the connection of weak parts of the structure; it is in this context that rebar planting technology came into being. By implanting steel bars in existing concrete structures and using high-performance adhesives to achieve a close combination of steel bars and concrete, the overall mechanical properties, seismic performance and durability of the structure are significantly improved to meet the growing technical needs of modern building renovation and reinforcement projects.

[0003] In current operational practices, when planting rebar, it is often necessary to first detect the position of the rebar in the existing building structure, and then perform the drilling operation after the detection is completed. Patent publication number CN216434397U discloses a detection device for detecting the position of rebar; however, this step-by-step operation will increase the time span of the construction process, and the rebar detection process and the drilling operation cannot be efficiently connected, resulting in low overall construction efficiency; in addition, after the rebar detection is completed and the position is recorded, drilling is performed. During this period, the recorded position may deviate due to slight changes in the construction environment or human factors, thereby increasing the risk of inaccurate drilling position, which may pose a potential threat to the stability of the building structure.

[0004] Therefore, there is a need for a linkage device that can detect the presence of steel bars and effectively punch holes during the rebar planting process to improve the quality and efficiency of building structure renovation and reinforcement projects. Utility Model Content

[0005] In view of this, the purpose of the present invention is to provide an obstacle-avoiding punching device for anchoring, which is a linkage device that can detect the presence of steel bars and effectively punch holes during the anchoring process, thereby improving the quality and efficiency of building structure renovation and reinforcement projects.

[0006] To achieve the above-mentioned purpose, the present invention provides an obstacle-avoiding drilling device for planting steel bars, comprising a body, a drill rod provided on the body, a first driving mechanism for driving the drill rod to rotate, and a first power supply for powering.

[0007] The machine body is also connected to a steel bar detector, which is used to detect whether there is a steel bar in front of the drill rod and to provide a prompt.

[0008] As a further improvement to the technical solution of the utility model, the steel bar detector includes a detection coil, an inductance-to-digital converter, a processor, a prompter and a second power supply for power supply connected in sequence;

[0009] When a steel bar enters the alternating magnetic field generated by the detection coil, the inductance value of the detection coil changes; the inductance-to-digital converter obtains the required measurement results by detecting the change in the inductance value in the coil; the processor processes the inductance value data read from the inductance-to-digital converter and triggers the indicator after determining the distance to the steel bar according to a preset algorithm.

[0010] As a further improvement to the technical solution of the present utility model, the inductance-to-digital converter is LDC1000, and the processor is the main control chip C8T6.

[0011] As a further improvement to the technical solution of the present utility model, the prompter includes a buzzer and / or an indicator light.

[0012] As a further improvement to the technical solution of the present invention, the steel bar detector is mounted on the machine body via a detachable mounting bracket.

[0013] As a further improvement to the technical solution of the present utility model, the mounting bracket includes a first mounting plate, a second mounting plate and a plurality of telescopic rods; the second mounting plate is fixed to the machine body and is located behind the drill rod; the first mounting plate and the second mounting plate are connected and maintained parallel by telescopic rods; the length of the telescopic rods is adjustable, so that the distance between the first mounting plate and the second mounting plate can be adjusted;

[0014] A through hole for the drill rod to pass through is provided in the first mounting plate, the detection coil is also fixed in the through hole, and the inductance-to-digital converter, processor and prompter are all fixed on the first mounting plate.

[0015] As a further improvement to the technical solution of the present invention, the steel bar detector further includes a second driving mechanism for driving the telescopic rod to extend and retract.

[0016] As a further improvement to the technical solution of the present utility model, the machine body is provided with a first main switch for opening and closing the first driving mechanism and a second main switch for opening and closing the second driving mechanism.

[0017] As a further improvement to the technical solution of the present invention, a first sub-switch for controlling the connection of the second power supply circuit and a second sub-switch for controlling the detection opening and closing are provided on the first mounting plate.

[0018] As a further improvement to the technical solution of the present utility model, the first power source and the second power source are both battery structures.

[0019] Compared with the prior art, the present invention has the following beneficial technical effects:

[0020] The utility model provides an obstacle-avoiding punching device for rebar planting. Due to the addition of a rebar detector, the rebar detector can detect whether there is a rebar in front of the drill rod and give a prompt. If the detected area detects the presence of rebar, the operator is prompted that this area cannot be punched. If the detected area does not detect the presence of rebar, the operator is prompted that this area can be punched normally, and the drill rod can be driven to rotate at this time. The utility model realizes the linkage control of the detection unit and the punching unit, effectively avoiding the errors that may be caused by first detecting the mark and then punching in the traditional rebar planting process, improving the construction quality, reducing the number of processes, and improving the construction efficiency.

[0021] Advantages of additional aspects of the present invention will be partially given in the following description, and partially become apparent from the following description, or learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings of the present invention.

[0027] Example 1

[0028] like Figure 1 As shown: This embodiment provides a punching device, which is mainly used for rebar planting operations and can avoid being obstructed by the original steel bars. Therefore, it is an obstacle-avoiding punching device for rebar planting, including a body 1, a drill rod 2 arranged on the body 1, a first driving mechanism (not shown in the figure) for driving the drill rod 2 to rotate, and a first power supply 3 for powering.

[0029] The body 1, the drill rod 2 and the first drive mechanism can be the structure of an existing hand-held wall punch, and its structure and principle will not be described in detail here; the body 1 can be "T"-shaped or "L"-shaped, the first drive mechanism and the first power supply 3 are arranged inside the body 1, and most of the drill rod 2 is exposed from the front end; the first power supply 3 can be AC ​​power or a battery; the body 1 is provided with a first main switch 15 for turning on and off the first drive mechanism.

[0030] The present embodiment provides an obstacle-avoiding punching device for planting rebar, the main improvement of which is that a rebar detector is also connected to the machine body 1, and the rebar detector is used to detect whether there is a rebar in front of the drill rod 2 and provide a prompt.

[0031] Due to the addition of a steel bar detector, the steel bar detector can detect whether there are steel bars in front of the drill rod 2 and give a prompt. If steel bars are detected in the detected area, the operator is prompted that this area cannot be drilled. If no steel bars are detected in the detected area, the operator is prompted that this area can be drilled normally, and the drill rod 2 can be driven to rotate.

[0032] The steel bar detector can adopt a variety of structures. For example, in this embodiment, the steel bar detector includes a detection coil 4, an inductance-to-digital converter 5, a processor 6, an indicator and a second power supply for power supply connected in sequence; when the steel bar enters the alternating magnetic field generated by the detection coil 4, the inductance value of the detection coil 4 changes; the inductance-to-digital converter 5 obtains the required measurement results by detecting the change in the inductance value in the coil 4; the processor 6 processes the inductance value data read from the inductance-to-digital converter 5, and triggers the indicator after determining the steel bar distance according to a preset algorithm.

[0033] The detection coil 4 serves as a sensor probe. When a metal object (mainly steel bars in this embodiment) approaches, the inductance value of the detection coil 4 will change. This is because when the metal object enters the alternating magnetic field generated by the detection coil 4, eddy currents will be generated on the surface of the metal object. The reverse magnetic field generated by the eddy currents interacts with the electromagnetic field of the coil, causing the inductance value of the coil to change.

[0034] The inductance-to-digital converter 5 is preferably LDC1000, which detects the position of the metal object by detecting the change in the inductance value of the detection coil 4. The processor 6 is preferably the main control chip C8T6, which processes the inductance value data read from the LDC1000 and determines the distance between the object and the probe or other relevant parameters according to a pre-set algorithm. The output result can be used to trigger an alarm, start a device, etc. In this embodiment, a prompter is triggered, which can include a buzzer 7 and an indicator light 8. The buzzer 7 emits an audible alarm, and the indicator light 8 can be an LED light with different color combinations (for example, if no steel bars are detected in the detected area, the indicator light 8 lights up in green, prompting the operator to stop the detection first. If the detection component works normally, the indicator light 8 lights up in green. If the detection component fails to work normally, the indicator light 8 lights up in blue and the buzzer 7 is powered on to sound an alarm).

[0035] The second power supply 8 can also be a mains power supply or a battery structure.

[0036] Example 2

[0037] The obstacle-avoiding punching device for planting rebar provided in this embodiment is a further improvement on the structure shown in the first embodiment, so the same structure and principles between the two will not be repeated here.

[0038] In this embodiment, the steel bar detector can be connected to the body 1 in an existing reasonable manner; for example, in this embodiment, the steel bar detector is mounted on the body 1 through a detachable mounting bracket; specifically, the mounting bracket includes a first mounting plate 9, a second mounting plate 10 and a plurality of telescopic rods 11; the second mounting plate 10 is fixed on the body 1 and is located on the rear side of the drill rod 2; the first mounting plate 9 and the second mounting plate 10 are connected and kept parallel by the telescopic rod 11; the length of the telescopic rod 11 is adjustable, so that the distance between the first mounting plate 9 and the second mounting plate 10 is adjustable; a through hole is opened in the first mounting plate 9 for the drill rod 2 to pass through, and the detection coil 4 is also fixed in the through hole, and the inductance-to-digital converter 5, processor 6 and prompter are all fixed on the first mounting plate 9.

[0039] The first mounting plate 9 and the second mounting plate 10 can be rectangular plates, circular plates or other structures with a central opening structure; the second mounting plate 10 can be connected to the body 1 through a corresponding threaded pair; the middle part of the detection coil 4 is also an open structure, so that the drill rod 2 can pass through; the detection coil 4 can be fixed to the first mounting plate 9 by embedding, bonding or other methods; the inductance-to-digital converter 5, processor 6 and prompter are all installed on the side of the first mounting plate 9 close to the body 1, and the installation method can be screw fixing.

[0040] The number of telescopic rods 11 can be, for example, three, and preferably they are evenly distributed (for example, they can be evenly distributed along the circumference); the telescopic rod 11 can be a manually adjustable or electrically adjustable structure. Preferably, the steel bar detector also includes a second drive mechanism (not shown in the figure) for driving the telescopic rod 11 to extend and retract; the second drive mechanism can adopt an existing reasonable structure, for example, an electric push rod can be additionally provided, or one or all of the telescopic rods 11 can be provided with an electric push rod structure; at this time, a second main switch 14 for opening and closing the second drive mechanism can also be provided on the body 1 to facilitate control of the extension and retraction of the telescopic rod 11.

[0041] In this embodiment, the first mounting plate 9 may be provided with a first auxiliary switch 12 for controlling the connection of the power supply circuit of the second power source 8 and a second auxiliary switch 13 for controlling the detection on and off.

[0042] During use, the operator only needs to hold the handle of the body 1, place the device close to the wall, first press the first auxiliary switch 12, and then press the second auxiliary switch 13. The steel bar detector starts working and detects whether there are steel bars in the area in front of the drill bit. If steel bars are detected, the buzzer 7 will alarm and the indicator light 8 will light up in red. If no steel bars are detected, the indicator light 8 will light up in green. The operator decides whether to drill according to the signal prompt of the indicator light 8. If drilling, it is only necessary to first press the first auxiliary switch 12 to stop the detection, then press the second main switch to retract the first mounting plate 9, and then press the first main switch to drill. After drilling is completed, if you want to continue the detection, you only need to first press the second main switch to extend the first mounting plate 9, then press the second auxiliary switch 13 to start the detection, and repeat the above operation. To end the detection, you only need to press the first auxiliary switch 12 to stop the power supply to the detector. During this operation, if the detector is operating normally, the indicator light 8 will light up in green. If the detector is operating abnormally, the buzzer 7 will alarm and the indicator light 8 will light up in blue.

[0043] The above is only an embodiment of the present invention, and the commonly known specific structures and characteristics of the scheme are not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, and these should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection claimed by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
