Technical Field

[0001] This invention relates to the technical field of building engineering, and in particular to a drilling device for rebar installation in narrow pits. Background Technology

[0002] Rebar anchoring, also known as rebar installation, is a post-anchoring connection technique for reinforcing steel bars in seismic reinforcement engineering of building structures. It utilizes the locking force of structural adhesive to achieve the final bond. It is the optimal choice for structural reinforcement and heavy-load fastening applications. Chemical rebar anchoring involves drilling holes in concrete, wall, or rock substrates and then injecting high-strength anchoring adhesive (note: high-strength building anchoring adhesives are generally divided into injection-type and barrel-type adhesives). After the rebar or profile is inserted and the adhesive cures, it bonds the rebar to the substrate, making it a commonly used construction engineering technique in the reinforcement industry.

[0027] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0028] This invention discloses a drilling device for rebar installation in narrow pits.

[0029] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4A drilling device for rebar installation in narrow pits includes a vehicle body 1, a fixing device 2, a drilling and welding device, and a dust extraction assembly 22. The vehicle body 1 serves as the main load-bearing component and has a moving component, allowing it to be driven to move. The fixing device 2 is mounted on the vehicle body 1 and has a clamping part for restricting the movement of the vehicle body 1. The vehicle body 1 has a storage bin 3 for storing rebar 4, and the storage bin 3 has a feeding channel 23 through which the rebar 4 can pass. The drilling and welding device includes a drilling assembly and an electroslag pressure welding device. The electroslag pressure welding device includes an electrode part 5 and a welding box 6, which contains welding flux. The drilling assembly includes an electric drill. 7. Connecting seat 8, rotating part 9, clamping assembly 10 and telescopic rod 11. The telescopic rod 11 is drivable and is located between the connecting seat 8 and the vehicle body 1. The rotating part 9 is drivable and is rotatably fitted at the bottom of the connecting seat 8. When drilling, the clamping assembly 10 clamps or releases the electric drill 7. The rotating part 9 is used to drive the electric drill 7 to rotate. The telescopic rod 11 drives the welding box 6 to rise and fall vertically to apply downward pressure to the electric drill 7. When welding, the clamping assembly 10 clamps the reinforcing bar 4. The telescopic rod 11 moves the welding box 6 to the connection point of the reinforcing bar 4. The electrode part 5 energizes the reinforcing bar 4 located in the feeding channel 23 to complete the welding.

[0030] After starting the telescopic rod 11 and adjusting the electric drill 7 to the designated lower position, start the telescopic rod 11 and drive the electric drill 7 to rotate, so that the electric drill 7 drills a hole downwards. After drilling is completed, the clamping assembly 10 releases the electric drill 7, the vehicle body 1 rises, and the reinforcing bar 4 falls through the feeding channel 23. Then, the welding box 6 is driven to move to the connection point between the reinforcing bar 4 and the electric drill 7. The electroslag pressure welding device clamps the lower drill bit and the upper reinforcing bar 4, starts the power supply to perform welding, and then lifts upwards to continue welding to complete the rebar installation. This patent can replace welding and drilling in narrow openings that cannot be constructed manually, avoids dangerous construction for personnel, and solves the problem that people cannot enter narrow openings to weld and that rebar cannot be installed at the bottom of narrow openings.

[0031] In this embodiment, the vehicle body 1 serves as the main load-bearing component. The vehicle body 1 is divided into upper and lower split sections. The moving component is located on the lower vehicle body 1 and consists of drive wheels. The drive wheels are driven by remote control using existing technology. Here, the details of how the vehicle body 1 is driven to move and steer will not be elaborated upon.

[0032] In this embodiment, the device is placed at the opening or protruding component (a hollow, narrow steel pipe, or a deep, narrow hole). Once in the designated position, the fixing device 2 clamps the opening or both sides of the component. The fixing device 2 is located on the lower body 1. In this embodiment, the fixing device 2 includes two clamping plates spaced laterally. Each clamping plate has a clamping part for fixing the reinforcing bar 4 or the drill bit. The clamping part has balls that rotatably mount on the inner wall of the clamping part, with multiple balls spaced apart along the inner wall, allowing the clamping part to hold the reinforcing bar 4, thus allowing the drill bit to rotate without affecting its drilling. The body 1 is equipped with a driving component that drives the two clamping plates to face each other or move away from each other. In this embodiment, the driving component is a bidirectional screw.

[0033] In this embodiment, the upper vehicle body 1 and the lower vehicle body 1 are connected by an electric push rod and a guide rod. The electric push rod is used to drive the upper vehicle body 1 to move up and down. A drilling and welding device is installed on the upper vehicle body 1. When the upper vehicle body 1 is pushed up and down by the electric push rod, the drilling and welding device moves up and down along with it.

[0034] In this embodiment, a pressure detection sensor 17 is provided at the movable end of the telescopic rod 11. The pressure detection sensor 17 is used to detect the pressure on the connecting seat 8. A control system is provided inside the vehicle body 1. The control system uses a CPU and its peripheral circuits, which are existing technologies and will not be described in detail here. The control system has a preset pre-tightening pressure value, which is used to detect whether the electric drill 7 is kept in a tight state against the hole or component, and the electric drill 7 can be detected to have disengaged by the corresponding pressure value.

[0035] After drilling is completed, the clamping assembly 10 separates from the drill 7, fixing the drill 7 to the hole or component. The clamping assembly 10 and the telescopic rod 11 are connected and extended. In this embodiment, the telescopic rod 11 is an electric cylinder. The telescopic rod 11 is located between the connecting seat 8 and the vehicle body 1. When drilling, the telescopic rod 11 expands, applying downward pressure to the drill 7, causing the drill 7 to press firmly against the hole or component, making drilling more convenient and efficient.

[0036] In this embodiment, the rotating part 9 is rotatably mounted on the bottom of the connecting seat 8. In this embodiment, the connecting seat 8 is provided with a driving member 12, which is a motor, a driving gear, and a driven gear. The motor drives the driving gear to rotate, and the driven gear is coaxially mounted on the rotating part 9. The driving gear and the driven gear mesh, thereby driving the rotating part 9 to rotate. The axis of the rotating part 9 and the connecting seat 8 is provided with a feeding channel 23 that communicates with the feeding channel 23. The steel bar 4 located in the feeding channel 23 falls into the feeding channel 23 and can continue to fall from the feeding channel 23.

[0037] When drilling, the clamping assembly 10 clamps or releases the electric drill 7, the rotating part 9 drives the electric drill 7 to rotate, and the telescopic rod 11 drives the welding box 6 to rise and fall in the vertical direction to apply downward pressure to the electric drill 7; when welding, the clamping assembly 10 clamps the reinforcing bar 4, the telescopic rod 11 moves the welding box 6 to the connection point of the reinforcing bar 4, and the electrode part 5 energizes the reinforcing bar 4 located in the feeding channel 23 to complete the welding.

[0038] In this embodiment, the electrode part 5 is located at the outlet of the feeding channel 23, and the vehicle body 1 has a built-in power supply for charging the electrode part 5. An insulating layer is provided inside the vehicle body 1. After the electrode part 5 is energized, the insulating layer insulates the interior of the vehicle body 1, ensuring that current can only be conducted through the reinforcing bar 4, thus guaranteeing the safety of the interior of the vehicle body 1. During welding, the welding box 6 is first moved to the joint, then filled with welding flux, and then moved upwards a certain distance. The power is then turned on, causing the welding box 6 to form an electroslag pool, melting the reinforcing bar 4. Then, the telescopic component extends, slowly lowering the reinforcing bar 4. After the power is cut off, the telescopic component quickly extends, extruding the molten metal and slag to form a joint. A pressure sensor is used during this process to detect the pressure of the reinforcing bar 4 during welding, thereby determining whether the welding of the reinforcing bar 4 is secure. At this time, the fixing device 2 fixes the welded reinforcing bar 4 or the electric drill 7 to ensure concentricity.

[0039] In this embodiment, the welding box 6 includes a first welding box 6 and a second welding box 6. A connecting member 13 is provided on the connecting seat 8. The first welding box 6 and the second welding box 6 are disposed on the connecting seat 8 through corresponding connecting members 13. The connecting members 13 can drive the first welding box 6 and the second welding box 6 to move towards or away from each other. In this embodiment, the connecting member 13 is an L-shaped part, with an electric cylinder arranged in both the horizontal and vertical directions, together forming an L-shape. This allows the welding box 6 to move in both the vertical and horizontal directions, closing or opening the welding box 6, and simultaneously adjusting the height of the welding box 6.

[0040] In this embodiment, a flux storage chamber for storing welding flux is provided inside the vehicle body 1. The welding flux is loaded into the flux storage chamber. A material conveying channel is provided inside the connecting seat 8. A pipe 15 is provided between the flux storage chamber and the material conveying channel. In this embodiment, the pipe 15 is a corrugated pipe that can extend and retract vertically. The rotating part 9 has a discharge hole communicating with the material conveying channel. When discharging welding flux, the rotating part 9 is activated to ensure that the welding flux falls evenly into the welding box 6, avoiding uneven accumulation of welding flux and affecting the welding effect.

[0041] The inner wall of the welding box 6 is provided with a guide surface 14. The welding flux inside the welding box 6 can be separated from the welding box 6 through the guide surface 14. After the first welding box 6 and the second welding box 6 are separated, the welding flux inside the welding box 6 falls to the ground through the guide surface 14. With the rapid extension and retraction of the telescopic rod 11, the welding flux inside the welding box 6 is shaken off, making it convenient for the next use.

[0042] A ball bearing 16 is provided on the inner wall of the welding box 6 where it contacts the electric drill 7. A fixing groove is provided on the inner wall of the electric drill 7, and an elastic element is provided in the fixing groove. The elastic element is used to drive the ball bearing 16 to move outward. When the elastic element is in a fully compressed state, the ball bearing 16 protrudes slightly from the inner wall. When the welding box 6 is closed, the ball bearing 16 contacts the electric drill 7. When the electric drill 7 rotates, the ball bearing 16 acts as a bearing to facilitate the rotation of the electric drill 7.

[0043] In this embodiment, a limiting member 18 is provided on the side wall of the feeding channel 23. The drivable extension of the limiting member 18 causes the movable end of the limiting member 18 to press against the steel bar 4 in the feeding channel 23. Specifically, the limiting member 18 includes an electric cylinder and a rubber pad. When drilling and welding are performed, it prevents the remaining steel bar 4 from falling out of the feeding channel 23 and restricts its sliding in the feeding channel 23, ensuring that the steel bar 4 located in the feeding channel 23 rises and falls together with the vehicle body 1 during the welding process.

[0044] In this embodiment, a moving assembly for moving the steel bar 4 to the feeding channel 23 is provided in the storage bin 3. The moving assembly includes a moving plate 19 and a spring 20. The moving plate 19 is slidably disposed in the storage bin 3. The spring 20 is used to drive the moving plate 19 to move towards the feeding channel 23, so that the steel bar 4 moves closer to the feeding channel 23 under the action of the moving plate 19 and falls out from the dropping channel.

[0045] In this embodiment, a limiting member 21 is provided inside the storage chamber 3. The limiting member 21 can be manipulated to restrict the movement of the reinforcing bars 4 inside the storage chamber 3 towards the feeding channel 23. Specifically, the limiting member 21 is an electric cylinder and a rubber pad. When one of the reinforcing bars 4 falls into the feeding channel 23, the limiting member 21 extends to press against the remaining reinforcing bars 4 in the storage chamber 3, preventing them from entering the feeding channel 23 and separating the two to prevent electrical conductivity.

[0046] In this embodiment, a sensor, specifically an infrared sensor, is installed in the material drop channel to detect whether a steel bar 4 has fallen into the material drop channel. When detected, the limiting component 21 is activated.

[0047] The dust collection component 22 includes an adsorption element and a debris compartment disposed on the vehicle body 1. The adsorption element is used to suck debris into the debris compartment. The adsorption element is a vacuum cleaner. The debris compartment is built into the vehicle body 1 and is used to absorb fallen electroslag. This is existing technology and will not be described in detail here.

[0048] By adopting the above technical solution, the drilling and rebar installation process has been automated, which not only solves the problem of drilling and rebar installation in narrow spaces, but also enables automatic rebar installation and improves work efficiency.

[0049] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
