Description

Technical Field

[0001] This utility model relates to the field of drilling equipment technology, specifically to a drilling component of an exterior wall repair climbing robot. Background Technology

[0002] Drilling holes in building exterior walls is a crucial process. Precise control over the location and size of these holes not only affects the quality and effectiveness of the repair but also directly impacts the building's safety and lifespan. In practice, drilling is often done using handheld drilling equipment, with workers standing on suspended platforms. However, these platforms are unstable and lack grip, making drilling difficult and inefficient.

[0003] The prior art (CN217345469U) discloses a drilling robot, relating to the field of drilling equipment technology, including a drilling gun, an infrared depth camera, a mounting base, a six-axis robotic arm, and a walking device. The infrared depth camera is mounted on the top of the drilling gun, and the lower part of the drilling gun is fixedly connected to the head end of the six-axis robotic arm, which is used to adjust the position of the drilling gun. The tail end of the six-axis robotic arm is fixedly connected to the walking device. The infrared depth camera includes a camera and an infrared emitter, both facing directly above the drill bit of the drilling gun. The walking device includes a chassis support and tracks, as well as guide wheels located on both sides of the front of the chassis support and drive wheels located on both sides of the rear of the chassis support. The guide wheels on one side of the chassis support are engaged with the drive wheels via the tracks. Although this solution frees up manual labor to some extent, automatically positions the drilling hole, and ensures high-precision drilling quality, in actual use, it can only operate on the ground or still relies on a suspended platform. Its walking mechanism cannot move on walls, and the drilling gun lacks cooling, making long-term operation impossible. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a drilling component suitable for a wall-climbing robot for exterior wall repair. This aims to address the existing lack of drilling tools suitable for exterior wall repair robots. Current exterior wall repair drilling processes mainly use handheld drilling tools for manual drilling. Since the person stands on a basket or hangs from ropes, there is no point of leverage during drilling, resulting in poor drilling accuracy and low efficiency. Using a drilling component suitable for a wall-climbing robot for exterior wall repair, the robot's suction force on the wall surface and its motion control can achieve stable drilling and precise drilling position. Furthermore, this drilling component uses a water-cooled drill with a water circulation system, enabling dust-free drilling, low noise, and excellent environmental friendliness.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A drilling component is used in an exterior wall repair robot. The drilling component includes a drilling mechanism and a water circulation system. The drilling mechanism includes a servo cylinder, a reducer, a motor, and a drill rod assembly. The servo cylinder is mounted on a sliding platform module of the wall-climbing robot. The reducer is connected to the servo cylinder, the motor is connected to the reducer, and the drill rod assembly is connected to the reducer. The water circulation system includes a water supply component, a water tank, a drainage component, and a filter component. The water supply component is connected to the inlet of the drill rod, and the drainage component is connected to the outlet of the drill rod assembly.

[0007] Preferably, the drill rod assembly includes a rotary joint, a water inlet, a compression spring, a drill rod bracket, an upper sealing ring, a lower sealing ring, a water outlet, a drill rod, and a drill bit. One end of the rotary joint is connected to the output shaft of the reducer, and the water inlet is connected to the rotary joint. The compression spring is placed inside the drill rod bracket and connected to the upper sealing ring, while the lower sealing ring is connected to the end of the drill rod bracket. One end of the drill rod is connected to the rotary joint, and the other end is connected to the drill bit. After the rotary joint, drill rod, and drill bit are connected, they are placed inside the drill rod bracket and can slide inside the drill bit bracket. During sliding, the compression spring is compressed, causing extension and contraction.

[0008] Preferably, the water supply component draws clean water from the water tank for drilling cooling and chip removal, and the drainage component draws wastewater to the filter component, where it is purified and then flows back to the water tank, thus realizing water recycling.

[0009] Preferably, the water outlet is connected to the drill rod bracket, the drill rod is connected to one end of the rotary joint and passes through the compression spring, the upper sealing ring and the lower sealing ring, and extends out from inside the drill rod bracket, and the drill bit is connected to the drill rod.

[0010] Preferably, the reducer is equipped with a guide mechanism, which is an oil-free bushing, a slide rail, or a guide hole.

[0011] Preferably, the reducer includes a water inlet connector limiting plate and a linear guide rail cover plate, which are connected to the reducer base plate.

[0012] Preferably, the drill pipe support structure is used in conjunction with the guide structure on the reducer, and the drill pipe support has a guide rod or a slider.

[0013] Preferably, the reducer includes an output shaft, an electric cylinder connecting plate, a reducer base plate, a linear guide cover plate, a linear guide, and a water pipe connector limiting plate, wherein the output shaft is connected to the drill rod assembly, the electric cylinder connecting plate is connected to the servo electric cylinder, the reducer base plate is connected to the motor, and the linear guide is connected to the drill rod support.

[0014] Preferably, the reducer includes an output shaft, an electric cylinder connecting plate, and a reducer base plate, wherein the output shaft is connected to the drill rod assembly, the electric cylinder connecting plate is connected to the servo electric cylinder, and the reducer base plate is connected to the motor and the drill rod support.

[0015] Preferably, the lower sealing ring is compressible, and after compression, it adheres to the wall surface to form a seal.

[0016] The above provides several alternative methods, but these are not intended as additional limitations on the overall solution. They are merely further additions or optimizations. Provided there are no technical or logical contradictions, each alternative method can be combined individually with respect to the overall solution, or multiple alternative methods can be combined with each other.

[0017] The present invention provides a drilling component suitable for an exterior wall repair robot, which has the following advantages compared with the prior art:

[0018] 1) This utility model solves the problems of poor drilling accuracy and low efficiency caused by combining a wall-climbing robot with a drilling mechanism. In addition, the existing wall drilling is mostly done manually using hand-held drilling tools. Since people stand on the basket or hang on the rope, there is no point of force during the drilling process. At the same time, there are also great safety risks for people to work at height.

[0019] 2) The drilling component of this utility model adopts a combination of servo electric cylinder, drill rod support guide, and compression spring. The drill rod is fed by the reaction force of the servo electric cylinder and the wall surface on the drill rod support. When it leaves the wall surface, it is reset by the action of the compression spring inside the drill rod support. Unlike manual operation based on experience, the servo electric cylinder can effectively control the feed speed and feed depth, ensuring the consistency of the size and depth of each hole and ensuring the construction quality.

[0020] 3) The drilling component of this utility model adopts a flexible sealing ring and a water circulation system. When the motor drill rod rotates, the water circulation system is started at the same time. On the one hand, the water reduces the temperature of the drill bit and increases the life of the drill bit. On the other hand, the drilled debris can be discharged through the water outlet and enter the filter component to filter and recycle the sewage. The flexible sealing ring can fit the wall surface with different curvatures to ensure that sewage does not seep out from the wall surface, thereby achieving clean and efficient drilling.

[0033] Example 1

[0034] like Figure 1 As shown, this embodiment provides a drilling component suitable for a wall-climbing robot for exterior wall repair, including a drilling mechanism 1 and a sewage circulation system 2.

[0035] The drilling mechanism 1 and the sewage circulation system 2 of this drilling component are mounted on the wall-climbing robot 3, enabling wall movement and positioning, such as... Figure 2 As shown, during the drilling process, clean water is drawn from the water tank 22 through the water supply component 21 in the water circulation system 2 for drilling cooling and chip removal. Wastewater is drawn from the drainage component 23 to the filter component 24, purified, and then flows back to the water tank 22, thus realizing water recycling.

[0036] Drilling structure 1 has telescopic drilling and end sealing functions, thus enabling drilling into walls with varying curvatures. For example... Figure 3 As shown, the drilling mechanism 1 in this embodiment includes a servo electric cylinder 11, a reducer 12, a motor 13, and a drill rod assembly 14, wherein the reducer 12 is connected to the servo electric cylinder 11, the motor 13, and the drill rod assembly 14 respectively.

[0037] like Figure 4 As shown, the reducer 12 includes an oilless bushing 121, an output shaft 122, an electric cylinder connecting plate 123, and a reducer base plate 124. The oilless bushing 121 and the output shaft 122 are connected to the drill rod assembly 14, the electric cylinder connecting plate 123 is connected to the servo electric cylinder 11, and the reducer base plate 124 is connected to the motor 13.

[0038] The drill pipe assembly 14 includes a rotary joint 141, a water inlet 142, a compression spring 143, a drill pipe bracket 144, an upper sealing ring 145, a lower sealing ring 146, a water outlet 147, a drill pipe 148, and a drill bit 149.

The lower sealing ring 146 is connected to the end of the drill pipe bracket 144. Figure 5 One end of the drill rod 148 is connected to the rotary joint 141, and the other end is connected to the drill bit 149. After the rotary joint 141, drill rod 148, and drill bit are connected, they are placed inside the drill rod support 144 and can slide inside the drill bit support 144. When sliding, the spring 143 is compressed to generate extension and contraction.

[0039] The drill rod support 144 is connected to the oil-free bushing 121 via a guide rod, ensuring that the drill rod support 144 slides axially along the oil-free bushing 121. When the servo cylinder 11 advances forward, the lower end sealing ring 146 of the drill rod support 144 contacts the wall surface. The lower end sealing ring 146 is compressed and forms a sealed space with the upper end sealing ring 145 and the wall surface inside the drill rod support 144. When the servo cylinder 11 continues to advance, the drill rod support 144 slides backward, and the drill bit 149 advances forward to grind and drill a hole in the wall surface.

[0040] The lower sealing ring 146 has good compression performance, good adhesion to the wall surface, and excellent sealing effect.

[0041] Example 2

[0042] This embodiment provides a drilling component suitable for a wall-climbing robot for exterior wall repair, including a drilling mechanism 1 and a sewage circulation system 2.

[0043] The drilling mechanism 1 and the sewage circulation system 2 of the drilling component are mounted on the wall-climbing robot 3 to achieve wall movement and positioning. During the drilling process, clean water is drawn from the water tank 22 through the water supply component 21 in the water circulation system 2 for drilling cooling and chip removal. Sewage is drawn from the drainage component 23 to the filter component 24, and after purification, it flows back to the water tank 22 to achieve water recycling.

[0044] The drilling structure 1 has telescopic drilling function and end sealing function, so it can drill holes in walls with different curvatures. The drilling mechanism 1 in this embodiment includes a servo electric cylinder 11, a reducer 12, a motor 13, and a drill rod assembly 14, wherein the reducer 12 is connected to the servo electric cylinder 11, the motor 13, and the drill rod assembly 14 respectively.

[0046] The linear guide cover 125 can prevent dust from entering the linear guide 126 and affecting the sliding effect.

[0047] The drill pipe assembly 14 includes a rotary joint 141, a water inlet 142, a compression spring 143, a drill pipe bracket 144, an upper sealing ring 145, a lower sealing ring 146, a water outlet 147, a drill pipe 148, and a drill bit 149.

After the rotary joint 141, drill pipe 148, and drill bit are connected, they are placed inside the drill pipe bracket 144 and can slide inside the drill bit bracket 144. During sliding, the compression spring 143 expands and contracts.

[0048] The drill rod support 144 is equipped with a slider that is connected to the slide rail 126 to ensure that the drill rod support 144 slides along the linear slide rail 126. When the servo electric cylinder 11 moves forward, the lower end sealing ring 146 of the drill rod support 144 contacts the wall surface. The lower end sealing ring 146 is compressed and forms a sealed space with the upper end sealing ring 145 and the wall surface inside the drill rod support 144. When the servo electric cylinder 11 continues to move forward, the drill rod support 144 slides backward and the drill bit 149 moves forward to grind and drill a hole in the wall surface.

[0049] The water pipe joint limiting plate 127 can restrict the water inlet 142 from rotating with the rotary joint 145.

[0050] The lower sealing ring 146 has good compression performance, good adhesion to the wall surface, and excellent sealing effect.
