Description

Technical Field

[0001] This invention relates to the field of laser technology, and in particular to a laser crushing device for nuclear power plant concrete. Background Technology

[0002] Laser technology, as a new type of environmentally friendly and non-contact technology, is widely used in aviation, aerospace, shipbuilding, petroleum, chemical, and microelectronics fields, such as laser cutting, laser cleaning, laser drilling, and laser marking. Because lasers can rapidly generate high-intensity heat, they have the ability to instantly destroy the molecular structure of concrete binders. Currently, some special enterprises using high-grade concrete, such as nuclear power plants, need to utilize the non-contact characteristics of lasers to crush and peel off high-grade concrete layer by layer to repair the interior of the walls, ensuring that the building structure and the components embedded inside the walls are not damaged. However, building repairs are usually high-altitude operations, and some building structures are quite special, requiring the device to enter narrow gaps to crush and peel off the concrete. Traditional manual excavation and rough mechanical cutting operations cannot achieve the ideal crushing and peeling effect. To meet market demand, we propose a laser crushing device for nuclear power plant concrete. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, this invention provides a laser crushing device for nuclear power plant concrete, which uses laser to destroy the molecular structure of concrete, forming a layer of silicate crystals on the concrete surface, and then uses grinding technology to crush and peel off the silicate crystals, thereby achieving the layer-by-layer peeling of concrete.

[0004] To achieve the above-mentioned technical objectives, the present invention provides the following technical solution:

[0005] A laser crushing device for nuclear power plant concrete includes a movable support base, a middle support arm, an upper support arm, a stripping working head, a high-pressure fixed suction cup, and a tank chain. The connections are as follows: the movable support base is movably connected to the side of the middle support arm; the upper support arm is movably connected above the middle support arm; the stripping working head is positioned above the upper support arm; the high-pressure fixed suction cup is mounted on the top of the upper support arm; and the tank chain is introduced from the lower end of the movable support base, passes through the middle support arm, and is fixed at its upper end inside the stripping working head.

[0006] The movable support base device consists of a support base body welded from iron blocks, which is wider at the bottom and narrower at the top, with an open interior, front, and top; a first slide rail; a first gear motor; a first universal wheel; a second universal wheel; a third universal wheel; a fourth universal wheel; a first foot cup; a second foot cup; a third foot cup; and a fourth foot cup.

[0007] The first slide rail is installed on the left and right sides inside the main body of the support base. The corresponding first slider is installed and fixed on the left and right sides near the bottom of the main body of the middle support arm. The first gear motor is installed on the left side near the top of the main body of the support base. Its gear meshes with the first rack installed on the left side of the main body of the middle support arm. When the first gear motor drives the gear to rotate, the middle support arm device can move up and down along the first slide rail. The first slide rail can make the middle support arm device move up and down more smoothly and stably, and play a guiding and auxiliary support role. The first universal wheel, the second universal wheel, the third universal wheel, the fourth universal wheel, the first foot cup, the second foot cup, the third foot cup, and the fourth foot cup are symmetrically installed at the four corners of the bottom of the main body of the support base. The universal wheel can make the movement of the entire device more convenient, while the foot cup can support and fix the device during operation, thereby making the operation more stable.

[0008] The intermediate support arm device includes an intermediate support arm body, a first rack, a first slider, a second rack, and a second slider;

[0009] The main body of the intermediate support arm is a rectangular tube with a hollow interior and open ends, welded from steel plates. A first rack is installed on the outer left side of the main body of the intermediate support arm. The first rack meshes with the gear of the first gear motor located near the top on the left side inside the support base body. The first slider is installed and fixed on the outer left and right sides of the main body of the intermediate support arm near the bottom. When the first gear motor drives the gear to rotate, the intermediate support arm can move up and down along the first slide rail. The second rack is installed on the front of the middle support arm near the right side. The second rack meshes with the gear of the second gear motor installed on the bottom right side of the upper support arm body. The second slider is installed on the outer left and right sides of the main body of the intermediate support arm near the top. The corresponding second slide rails are installed on the outer left and right sides of the upper support arm body. When the second gear motor rotates and drives the gear to rotate, the upper support arm can move up and down along the second slide rail. The second slide rail makes the upper support arm move up and down more smoothly and stably, and plays a guiding and auxiliary support role.

[0010] The upper support arm device includes an upper support arm body, a second slide rail, a third slide rail, a third rack, and a second gear motor. The upper support arm body is a hollow cuboid welded from steel plates. The second slide rail is installed and fixed on the left and right sides of the upper support arm body, providing support and guidance for the lifting and lowering of the upper support arm device, and also providing auxiliary support for the peeling head device, making it more stable when the peeling head device is in operation. The third slide rail is installed and fixed at the front center of the upper support arm body, used to support and guide the peeling head device to move up and down. The third rack is installed between the two rails of the third slide rail and meshes with the gear of the third gear motor installed on the peeling head device. When the third gear motor rotates, it drives the gear to rotate, which can make the entire peeling head device move up and down, thereby realizing the longitudinal operation of the device. The second gear motor is installed on the right side of the upper support arm body near the bottom, and its gear meshes with the second rack installed inside the front of the middle support arm device, providing power for the up and down movement of the upper support arm device.

[0011] The peeling head device includes a lead screw motor, an upper slider mounting base, an upper support arm, a lead screw, a peeling head, a lower support arm, a lower slider mounting base, a third gear motor, a first support block, a second support block, a first fixed bracket, a second fixed bracket, and a fourth gear motor.

[0012] One end of the upper support arm is movably connected to the upper slider mounting seat. The upper slider mounting seat has sliders on its left and right sides corresponding to the third slide rail on each side of its bottom. One end of the lower support arm is movably connected to the lower slider mounting seat. The lower slider mounting seat has sliders on its left and right sides corresponding to the third slide rail on each side of its bottom, and sliders on its inner sides corresponding to the second slide rail on each side. The other ends of the upper and lower support arms are movably connected to the first fixed bracket. The second fixed bracket is fixed to the first fixed bracket, forming a bracket capable of supporting the peeling head. A fourth gear motor is mounted on the second fixed bracket, and its gear meshes with a fourth rack mounted behind the peeling head. When the fourth gear motor rotates, it drives the gear to rotate, causing the peeling head to move left and right along the fourth slide rail mounted behind the head mounting seat, thus achieving lateral operation of the peeling head. The screw motor is installed... The lead screw, fixed to the left side of the upper slider mounting base and connected to the lead screw motor, is fixed at the top hollow position of the lower slider mounting base. When the lead screw motor rotates, it drives the upper slider mounting base to move up and down along the third slide rail, thereby allowing the peeling head to move in the depth direction for depth-oriented operation. The upper and lower support arms are respectively provided with a first support block and a second support block at the middle position below, to prevent the upper and lower support arms from overlapping and damaging the lines and pipes when the upper slider mounting base moves to the lower slider mounting base. It also makes the bracket carrying the peeling head more stable during operation. The third gear motor is fixed to the lower side of the lower slider mounting base, and its gear meshes with the third rack. When the third gear motor rotates, it drives the gear to rotate, which can drive the entire peeling head device to move up and down along the third slide rail, thereby achieving longitudinal operation of the peeling head.

[0013] The stripping head includes 4 sharpening blades, 4 water nozzles, a pneumatic sliding cover, a head mounting base, an annular air blowing hole, a laser emission hole, a rear cover, a reflector drive motor, a reflector, a protective lens, a camera, a laser head fixing hole, a fourth slide rail, a fourth rack, and a pipeline inlet.

[0014] The working head mounting base is fixed on the second fixed bracket and consists of two parts: a lens and a grinding section. To reduce contamination of the lens during the grinding process, the lens is located at the upper end of the working head mounting base, and the grinding section is located at the lower end. The lens has a laser head fixing hole inside for fixing the laser head. A laser emission hole is located above the laser head fixing hole. A rear cover for protection and fixation is installed behind the laser emission hole. A reflector is installed inside the rear cover, and a reflector drive motor connected to the reflector is installed outside the rear cover. When light is emitted, the reflector, driven by the reflector drive motor, allows the incident laser to be emitted from the laser emission hole and scan the concrete to be crushed and peeled. The laser is applied to the soil surface, enabling non-contact laser operation. The laser emission port is equipped with a protective lens to prevent dust and impurities from entering the laser lens cavity. An annular air blowing hole is provided on the outer side of the protective lens. During operation, a high-pressure air pump is connected to generate an outward airflow from the annular air blowing hole, thereby reducing lens contamination. A camera is provided below the laser emission port, which can achieve precise positioning before operation and monitor the peeling effect after operation. A pneumatic sliding cover is provided below the camera. The pneumatic sliding cover is connected to the high-pressure air pump. When laser operation or camera observation is performed, the pneumatic sliding cover is opened. When laser operation or observation is stopped, the pneumatic sliding cover is closed to prevent the laser lens and camera from being contaminated.

[0015] The four grinding blades are installed in front of the working head mounting base and are used to grind the concrete surface to form silicate crystals after being subjected to high temperature by the laser. Each grinding blade is equipped with a water nozzle at the rear top. When laser operation and grinding are performed, the water nozzle sprays water onto the wall surface at the same time. This serves two purposes: first, to cool the wall surface, which can quickly form silicate crystals in the concrete after being subjected to high temperature by the laser, and at the same time prevent the wall temperature from being too high and damaging the electronic components embedded in the wall; second, to allow the large amount of smoke and dust generated during laser operation and grinding to settle quickly, reducing pollution.

[0016] The fourth slide rail passes through the first and second fixed brackets and is fixedly installed behind the working head mounting base. The fourth rack also passes through the first and second fixed brackets and is fixedly installed behind the working head mounting base, meshing with the gear of the fourth gear motor mounted on the second fixed bracket. When the fourth gear motor rotates, it drives the gear to rotate, allowing the peeling working head to move left and right along the fourth slide rail, thereby realizing the lateral operation of the peeling working head. A pipeline inlet is provided at the center of the bottom of the working head mounting base for connecting the laser head, camera, and air pipeline.

[0017] The high-pressure fixed suction cup device is located on the top of the upper support arm device and includes a high-pressure suction cup base and a high-pressure suction cup. The high-pressure suction cup base is fixedly installed on the top of the upper support arm device and has a lead screw motor connected to the high-pressure suction cup installed inside. The high-pressure suction cup is installed in front of the high-pressure suction cup base and connected to the vacuum generator on the high-pressure air pump. The high-pressure suction cup can extend and retract back and forth through the lead screw motor inside the high-pressure suction cup base. Before grinding, the high-pressure suction cup is extended and pressed against the wall, and the air pump is turned on to make the high-pressure suction cup firmly adsorbed on the wall, which can make the grinding operation of the peeling head more stable. After grinding, the high-pressure suction cup is retracted back to its original position.

[0018] The tank chain is introduced from the lower end of the support base body, passes through the middle support arm device, and is fixed to the working head mounting seat at the upper end. It is used to pull and protect the air pipes, water pipes and cables built into the equipment, so as to prevent the air pipes, water pipes and cables from falling off or being damaged during the up and down reciprocating motion. This can ensure the normal operation of the equipment, reduce the occurrence of equipment failures, and increase the safety of the equipment.

[0019] The surfaces of the main body of the support base, the main body of the middle support arm, the main body of the upper support arm, the high-pressure suction cup base, the working head mounting seat, etc. are all provided with anti-rust coating, which can improve their corrosion resistance and help increase their service life.

[0020] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0021] 1. The device of the present invention can perform operations at different height positions, and simultaneously achieve precise longitudinal operation of the stripping head, precise depth operation of the stripping head, and precise lateral operation of the stripping head.

[0022] 2. The device of this invention enables rapid stripping of concrete during operation and reduces the dust generated during laser and grinding operations, effectively improving the working environment. It also cools the wall, preventing high-temperature damage to components embedded within the wall. It can not only perform pulverization and stripping operations at any height of the concrete wall, but also pulverize and strip it at any shape and depth. The operation process is highly controllable, causes no damage to the entire building structure, is safe and reliable, and produces a smooth and aesthetically pleasing stripped surface. It not only replaces inefficient manual excavation and rough mechanical cutting operations, but also reduces the high-intensity work of personnel, helping to alleviate work pressure. Furthermore, it eliminates the need for manual high-altitude operations, thus improving work safety.

[0023] 3. The peeling head of this invention adopts a miniaturized design, which allows it to operate in narrow gaps in special building structures where personnel cannot access them; the equipment is equipped with a camera, which can achieve precise positioning before operation and real-time observation of the peeling effect, preventing excessive crushing and peeling that could damage components buried inside the building walls; the equipment uses tank chains to protect air pipes, water pipes and cables, reducing equipment failures and increasing equipment safety; the equipment surface is coated with an anti-rust coating, which increases the equipment's corrosion resistance and thus extends its lifespan.

[0024] 4. The integrated design of this invention features a high degree of automation, stable operation, safety and reliability, simple structure, easy operation, low cost, corrosion resistance, long service life, and easy disassembly, maintenance and repair. It can also adapt to more scenarios of crushing and stripping concrete in building walls and complete concrete crushing and stripping operations with different requirements.

The third slide rail 303 is installed and fixed on the upper support arm body 301. The front middle position of 1 is used to support and guide the peeling head device 4 to move up and down. The third rack 304 is installed between the two rails of the third slide rail 303 and meshes with the gear of the third gear motor 408 installed on the peeling head device 4. When the third gear motor 408 rotates and drives the gear to rotate, the entire peeling head device 4 can move up and down, thereby realizing the longitudinal operation of the device. The second gear motor 305 is installed on the right side of the upper support arm body 301 near the bottom, and its gear meshes with the second rack 205 installed inside the middle support arm device 2 near the right side of the front.

Its gear meshes with the third rack 304. When the third gear motor 408 rotates and drives the gear to rotate, it can drive the entire peeling head device 4 to move up and down along the third slide rail 303, thereby realizing the longitudinal (Y) operation of the peeling head 405. Through the above-mentioned automated control, the peeling head can reach any height and realize crushing and peeling operations at any position, shape and depth.

The head mounting base 4054 is fixedly mounted on the second fixed bracket 412 and consists of two parts: lens and grinding. To reduce contamination of the lens during the grinding process... The lens portion is positioned at the upper end of the working head mounting base 4054, and the grinding portion is positioned at the lower end of the working head mounting base 4054. The lens portion has a laser head fixing hole 40512 inside for fixing the laser head. A laser emission hole 4056 is located above the laser head fixing hole 40512. A rear cover 4057, which provides protection and fixation, is installed behind the laser emission hole 4056. A reflector 4059 is installed inside the rear cover 4057, and a reflector drive motor 4058 connected to the reflector 4059 is installed outside the rear cover 4057. When light is emitted, the reflector 4059 is driven by the reflector drive motor 4058. The laser beam can be emitted from the laser emission hole 4056 and swept onto the surface of the concrete to be crushed and peeled, thus achieving non-contact laser operation. The laser emission hole 4056 is equipped with a protective lens 40510 to prevent dust and impurities from entering the laser lens cavity. An annular air blowing hole 4055 is located on the outer side of the protective lens 40510. During operation, a high-pressure air pump is connected to generate an outward airflow from the annular air blowing hole 4055, thereby reducing lens contamination. A camera 40511 is located below the laser emission hole 4056, enabling precise positioning before operation and real-time monitoring of the peeling effect after operation. A pneumatic sliding cover 4052 is provided at the lower position. The pneumatic sliding cover 4052 is connected to a high-pressure air pump. When laser operation or camera observation is performed, the pneumatic sliding cover 4052 is opened. When laser operation or observation is stopped, the pneumatic sliding cover 4052 is closed to prevent the laser lens and camera 40511 from being contaminated. The grinding part has four grinding blades 4051 installed in front of the working head mounting base 4054. These blades are used to grind the silicate crystals formed on the concrete surface after being subjected to high temperature by the laser. A water pipe nozzle 4053 is installed above and behind each grinding blade 4051. When laser operation and grinding are performed, the water pipe nozzle 4053 sprays water onto the wall surface at the same time.The fourth slide rail 40513 passes through the first fixed bracket 411 and the second fixed bracket 412 and is fixedly installed behind the working head mounting base 4054. The fourth rack 40514 also passes through the first fixed bracket 411 and the second fixed bracket 412 and is fixedly installed behind the working head mounting base 4054, meshing with the gear of the fourth gear motor 413 mounted on the second fixed bracket 412. When the fourth gear motor 413 rotates, it drives the gear to rotate, which allows the peeling working head 405 to move left and right along the fourth slide rail 40513, thereby realizing the lateral (X) operation of the peeling working head 405. A pipeline inlet 40515 is provided at the center of the bottom of the working head mounting base 4054 for the connection of the laser head, camera, and air pipeline. The annular vent and pneumatic sliding cover on the lens section of the 4054 working head mounting base prevent lens contamination, thereby effectively reducing equipment failure rate and greatly saving maintenance costs. Concrete forms easily grindable silicate crystals under the combined action of laser and water, and then is precisely ground with a grinding knife, which can effectively improve crushing and peeling efficiency.

[0041] like Figure 4 As shown, the high-pressure fixed suction cup device 5 is located on the top of the upper support arm device 3, including a high-pressure suction cup base 501 and a high-pressure suction cup 502. The high-pressure suction cup base 501 is fixedly installed on the top of the upper support arm device 3, and a screw motor connected to the high-pressure suction cup 502 is installed inside. The high-pressure suction cup 502 is installed in front of the high-pressure suction cup base 501 and connected to the vacuum generator on the high-pressure air pump. The high-pressure suction cup 502 can extend and retract back and forth through the screw motor inside the high-pressure suction cup base 501. Before the grinding operation, the high-pressure suction cup 502 is extended and pressed against the wall, and the air pump is turned on so that the high-pressure suction cup 502 is firmly attached to the wall, which can make the peeling head 405 more stable during the grinding operation. After the grinding is completed, the high-pressure suction cup 502 is retracted back to its original position.

[0042] like Figure 1 As shown, the tank chain 6 is introduced from the lower end of the support base body 101, passes through the intermediate support arm device 2, and is fixed at the upper end to the working head mounting seat 4054. It is used to pull and protect the built-in air pipes, water pipes, and cables of the equipment, preventing them from falling off or being damaged during the up-and-down reciprocating motion. This ensures the normal operation of the equipment, effectively reducing the equipment failure rate and increasing its safety. The surfaces of the support base body 101, intermediate support arm body 201, upper support arm body 301, high-pressure suction cup base 501, and working head mounting seat 4054 are all coated with an anti-rust coating, which improves their corrosion resistance and effectively extends the service life of the equipment.

[0043] During operation, first determine the location to be crushed and peeled. Then, activate the second gear motor 305 to raise the upper support arm 3. Next, activate the first gear motor 103 to raise the middle support arm 2 to the desired position. Open the pneumatic sliding cover 4052 and camera 40511 to observe and position the work area. Driven by the fourth gear motor 413, third gear motor 408, and lead screw motor 401, the peeling head 405 reciprocates laterally (X), longitudinally (Y), and in the depth direction (Z). After adjusting the peeling head 405 to the optimal position, turn on the laser switch. The laser head emits red light, which is reflected by the reflector 4059 onto the concrete surface to be crushed and peeled. The process is then adjusted according to the required parameters. The rotation angle of the reflector drive motor 4058 and the lateral (X) displacement distance of the peeling head 405 are set. After setting, the laser is turned on to perform high-temperature laser operation on the set concrete surface. At the same time, the four water pipe nozzles 4053 are turned on to spray the work area. When silicate crystals form on the concrete surface, the pneumatic sliding cover 4052 is closed, and the high-pressure suction cup 502 is attached to the wall. The four grinding blades 4051 are adjusted to the position to be ground, and the grinding blade motor is turned on to grind away the silicate crystals. This achieves layer-by-layer crushing and peeling operation at any position, shape, and depth. After grinding, the four water pipe nozzles are turned off, and the pneumatic sliding cover is turned on again. The crushing and peeling effect is observed through the camera.

[0044] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
