Description

Technical Field

[0001] The present invention relates to the technical field of demolition robots, in particular to an unmanned demolition robot. Background Art

[0002] A demolition robot is a special robot used in emergency rescue, building demolition and other fields. It can replace manual labor to perform demolition tasks in dangerous, complex or human-inaccessible environments, such as clearing debris after an earthquake and removing obstacles at a fire scene. It has a powerful power system and a variety of demolition tools, which can achieve efficient demolition of various building structures.

[0003] However, when the demolition robot is not working or being transported, the camera and lighting often lack effective protection and are easily eroded by external dust, sand and stones. Dust accumulates on the surface of the lens and lampshade, seriously reducing the camera imaging clarity, making it difficult for the operator to see the working environment clearly, and also affecting the light transmittance of the lighting, resulting in poor lighting effect, which affects subsequent demolition operations; when the demolition robot is performing bulldozing operations, due to the complexity of the working environment, a large amount of soil will inevitably adhere to the surface of the bulldozer plate. The accumulation of this soil will not only reduce the effective volume of the bulldozer plate, resulting in a decrease in the single bulldozing volume, thereby affecting the bulldozing efficiency; the working environment of the demolition robot is complex and changeable, and it often encounters rugged terrain, soft sand, slopes and other terrains. The existing support legs are inconvenient to adjust their position to adapt to the ground, resulting in an unstable center of gravity when the robot works in complex terrain, prone to tilting and overturning, and poor stability.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0034] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, the unmanned demolition robot described in the present invention includes a demolition robot body 1, a protective structure 2 installed on the demolition robot body 1, a heat dissipation structure 3 installed on the protective structure 2, an adjustment structure 4 installed on the demolition robot body 1, a support structure 5 installed on the demolition robot body 1 and the adjustment structure 4, an adjustment frame 7 installed on the demolition robot body 1, a bulldozer 8 installed on the adjustment frame 7, and a scraping structure 6 installed on the bulldozer 8; the protective structure 2 includes a mounting shaft 201 rotatably connected to the demolition robot body 1 and a fixedly connected to the mounting shaft 201. The protective cover 202 is provided with a frame 204, a filter 205 is provided on the frame 204, a vertical rod 206 is provided on the demolition robot body 1, and a rack 207 is fixedly connected to the vertical rod 206; the heat dissipation structure 3 includes two connecting shafts 301 rotatably connected to the protective cover 202 and a mounting frame 302 fixedly connected between the two connecting shafts 301, a plurality of axial flow fans 303 are provided on the mounting frame 302, a torsion spring 304 is fixedly connected between the connecting shaft 301 and the protective cover 202, and a gear 305 is fixedly connected to one of the connecting shafts 301.

[0035] Specifically, such as Figure 1 and Figure 2As shown, a first servo motor 203 is installed on the demolition robot body 1, and the mounting shaft 201 is fixedly connected to the output shaft of the first servo motor 203. During the demolition operation, the axial flow fan 303 is started, and the wind generated by the axial flow fan 303 will blow toward the camera and the lighting lamp. The start of the axial flow fan 303 can effectively blow away dust and prevent it from accumulating on the lens, thereby avoiding problems such as blurred imaging and weakened lighting effects caused by lens contamination, ensuring that the operator can clearly observe the working environment, and providing a strong guarantee for the smooth progress of the demolition work. At the same time, continuous blowing can also accelerate the air flow The first servo motor 203 can be started when the demolition robot is idle for a long time, and the output shaft of the first servo motor 203 drives the installation shaft 201 to rotate synchronously, and the installation shaft 201 drives the protective cover 202 to rotate. When the protective cover 202 rotates to a certain position, it will completely cover the camera and the lighting lamp, providing reliable protection for the equipment. During the idle period of the robot, it can effectively prevent dust from falling onto the equipment to avoid dust In addition, the filter 205 on the protective cover 202 has good ventilation performance. Even when the protective cover 202 covers the device, it can maintain air circulation to prevent moisture or excessive temperature inside the device due to poor air circulation, further protecting the performance and service life of the device. During the rotation of the protective cover 202, the gear 305 is driven to move until the gear 305 is engaged with the rack 207. At this time, the gear 305 starts to rotate and drives the connecting shaft 301 to rotate. During the rotation of the connecting shaft 301, the torsion spring 304 is deformed. The elastic potential energy is stored so that the connecting shaft 301 can be reversed later. The connecting shaft 301 continues to drive the installation frame 302 to rotate, and the installation frame 302 then drives the axial flow fan 303 to rotate. When the protective cover 202 is rotated into place, the installation frame 302 just rotates one hundred and eighty degrees. At this time, the axial flow fan 303 starts blowing. The wind blown by the axial flow fan 303 can blow away the dust on the filter 205, avoiding dust accumulation on the filter 205, and preventing the ventilation and heat dissipation effects from being affected by the blockage of the filter 205, thereby ensuring the continued effectiveness of the ventilation and heat dissipation functions of the protective cover 202 and further enhancing the protection of the camera and the lighting.

The four first screw rods 401 are respectively threadedly connected to four adjusting rods 501. Four worms 403 are rotatably connected in the demolition robot body 1. The four worms 403 are respectively engaged with four worm gears 402. There are two rotating shafts 404 rotatably connected in the demolition robot body 1. Two slide rods 409 are slidably connected in the rotating shaft 404. A spline shaft 410 is fixedly connected to the slide rod 409. A spline groove 408 is provided on the worm 403. A connecting block 411 is rotatably connected to the spline shaft 410. Four first hydraulic rods 412 are installed in the robot body 1, and the four connecting blocks 411 are fixedly connected to the telescopic ends of the four first hydraulic rods 412 respectively. A first pulley 405 is fixedly connected to the rotating shaft 404, and two second servo motors 407 are installed on the demolition robot body 1. A second pulley 406 is installed on the output shaft of the second servo motor 407. The first pulley 405 and the second pulley 406 are driven by a belt. When the support legs 506 are needed to support the demolition robot body 1 of the demolition robot, the hydraulic motor 504 is started, and the output shaft of the hydraulic motor 504 rotates, thereby driving the adjusting shaft 503 to rotate, and the adjusting shaft 503 drives the adjusting sleeve 505 to rotate, and the rotation of the adjusting sleeve 505 makes The four supporting legs 506 move synchronously, thereby cooperating to support the demolition robot body 1 and provide stable support for the demolition robot. In actual operation, if the position of a single supporting leg 506 needs to be adjusted, before the supporting leg 506 contacts the ground, the first hydraulic rod 412 can be started, and the telescopic end of the first hydraulic rod 412 extends to drive the connecting block 411 to move, and the connecting block 411 moves the spline shaft 410, and the spline shaft 410 drives the sliding rod 409 to slide with the rotating shaft 404. At the same time, the spline shaft 410 is plugged into the spline groove 408 on the worm 403. At this time, the second servo motor 407 is started, and its output shaft rotates to drive the second pulley 406 to rotate, and the second pulley 406 drives the first pulley 405 to rotate through the belt.The first pulley 405 drives the rotating shaft 404 to rotate, and the rotating shaft 404 is linked with the spline shaft 410 through the sliding rod 409 to rotate the worm 403, and the worm 403 drives the worm wheel 402 to rotate, and the worm wheel 402 drives the first screw rod 401 to rotate. When the first screw rod 401 rotates, the adjusting rod 501 is driven to extend out of the demolition robot body 1 through the thread, thereby adjusting the position of a single support leg 506 to ensure that each support leg 506 can better contact the ground and enhance the stability of the demolition robot. In addition, the third servo motor 508 can also be started, and its output shaft rotates to drive the second screw rod 507 to rotate, and the third servo motor 508 can be started. The second screw rod 507 drives the support leg 506 to slide within the adjustment sleeve 505 through a threaded connection. This sliding cooperation between the support leg 506 and the adjustment sleeve 505 further improves the support effect. When the support leg 506 extends outward from the adjustment sleeve 505 and cooperates with it, the angle of the adjustment sleeve 505 can be changed. The position and angle of the support leg 506 can be flexibly adjusted according to different working scenarios and terrain conditions. On uneven ground, by changing the angle of the adjustment sleeve 505 and extending the support leg 506 outward, the robot's center of gravity is better maintained within the support surface, preventing tilting or tipping, and enhancing stability on complex terrain.

[0037] Specifically, such as Figure 5As shown, the scraping structure 6 includes a second hydraulic rod 601 installed on the bulldozer blade 8 and an adjusting plate 602 installed on the telescopic end of the second hydraulic rod 601, the adjusting plate 602 is fixedly connected to the mounting plate 603, the mounting plate 603 is installed with a third hydraulic rod 604, the telescopic end of the third hydraulic rod 604 is installed with a scraper rod 605, and the bulldozer blade 8 is installed with a guide plate 606, and the adjusting plate 602 is slidably connected with the guide plate 606. First, when too much mud adheres to the surface of the bulldozer blade 8 on the demolition robot body 1 and needs to be cleaned, the second hydraulic rod 601 can be started. When the telescopic end of the second hydraulic rod 601 is extended, the adjusting plate 602 is driven to move. During the movement of the adjusting plate 602, it will slide and cooperate with the guide plate 606. The setting of the guide plate 606 plays a role of stable guidance, so that the adjusting plate 602 can slide smoothly. When the third hydraulic rod 604 is extended, the scraper rod 605 is driven to move. When the scraper rod 605 moves to the specified position, the adjusting plate 602 continues to move. At this time, the scraper rod 605 will scrape the soil on the bulldozer blade 8, avoiding a large amount of soil from continuously adhering to the bulldozer blade 8 and preventing the bulldozer resistance from increasing due to soil accumulation, thereby ensuring that the bulldozer operation can be carried out efficiently. After completing the soil scraping work, it is only necessary to fully retract the second hydraulic rod 601 and then retract the third hydraulic rod 604 to allow the scraper rod 605 to cooperate with the edge of the bulldozer blade 8. At this time, the remaining soil on the scraper rod 605 will fall under the action of its own gravity, allowing the scraper rod 605 to return to a clean state and prepare for the next cleaning work, ensuring that each cleaning can achieve good results.

[0038] When the present invention is in use, first, when too much mud adheres to the surface of the bulldozer blade 8 on the demolition robot body 1 and needs to be cleaned, the second hydraulic rod 601 can be started. When the telescopic end of the second hydraulic rod 601 is extended, it will drive the adjustment plate 602 to move. During the movement of the adjustment plate 602, it will slide with the guide plate 606. The setting of the guide plate 606 plays a role of stable guidance, so that the adjustment plate 602 can slide smoothly, thereby driving the mounting plate 603 to move synchronously. At the same time, the third hydraulic rod 604 can be started. When the telescopic end of the third hydraulic rod 604 is extended, it will drive the scraper rod 605 to move. When the scraper rod 605 moves to the specified position After that, the regulating plate 602 continues to move, and the scraper rod 605 will scrape the soil on the bulldozing blade 8, avoiding a large amount of soil from continuously adhering to the bulldozing blade 8, preventing the bulldozing resistance from increasing due to soil accumulation, and thus ensuring that the bulldozing operation can be carried out efficiently. After completing the soil scraping work, it is only necessary to fully retract the second hydraulic rod 601, and then retract the third hydraulic rod 604 to allow the scraper rod 605 to cooperate with the edge of the bulldozing blade 8. At this time, the remaining soil on the scraper rod 605 will fall under the action of its own gravity, allowing the scraper rod 605 to return to a clean state and prepare for the next cleaning work, ensuring that each cleaning can achieve a good effect.

[0039] When the support legs 506 are needed to prop up the demolition robot body 1, the hydraulic motor 504 is started, and the output shaft of the hydraulic motor 504 rotates, thereby driving the adjustment shaft 503 to rotate, and the adjustment shaft 503 in turn drives the adjustment sleeve 505 to rotate. The rotation of the adjustment sleeve 505 causes the four support legs 506 to move synchronously, thereby cooperating to prop up the demolition robot body 1 and provide stable support for the demolition robot. In actual operation, if the position of a single support leg 506 needs to be adjusted, the first hydraulic rod can be started before the support leg 506 contacts the ground. 412, the telescopic end of the first hydraulic rod 412 extends to drive the connecting block 411 to move, and the connecting block 411 causes the spline shaft 410 to move, and the spline shaft 410 drives the slide bar 409 to slide with the rotating shaft 404. At the same time, the spline shaft 410 is plugged into the spline groove 408 on the worm 403. At this time, the second servo motor 407 is started, and its output shaft rotates to drive the second pulley 406 to rotate. The second pulley 406 drives the first pulley 405 to rotate through the belt, and the first pulley 405 drives the rotating shaft 404 to rotate. The rotating shaft 404 rotates through the slide bar 409 The linkage with the spline shaft 410 causes the worm 403 to rotate, the worm 403 drives the worm wheel 402 to rotate, and the worm wheel 402 drives the first screw rod 401 to rotate. When the first screw rod 401 rotates, the adjusting rod 501 is driven to extend out of the demolition robot body 1 through the thread, thereby adjusting the position of a single support leg 506, ensuring that each support leg 506 can better contact the ground and enhance the stability of the demolition robot. In addition, the third servo motor 508 can also be started, and its output shaft rotates to drive the second screw rod 507 to rotate, and the second screw rod 507 drives the support leg through the thread. 506 slides in the adjustment sleeve 505. This sliding cooperation between the support leg 506 and the adjustment sleeve 505 further improves the support effect. When the support leg 506 extends out of the adjustment sleeve 505 and extends outward, the angle of the adjustment sleeve 505 can be changed. The position and angle of the support leg 506 can be flexibly adjusted according to different working scenarios and terrain conditions. On uneven ground, by changing the angle of the adjustment sleeve 505 and extending the support leg 506 outward, the center of gravity of the robot is better maintained within the support surface, preventing tilting or tipping, and enhancing stability on complex terrain.

[0040] During the demolition operation, the axial flow fan 303 is started, and the wind generated by the axial flow fan 303 will blow towards the camera and the lighting lamp. The start of the axial flow fan 303 can effectively blow away the dust and prevent it from accumulating on the lens, thereby avoiding problems such as blurred imaging and weakened lighting effects caused by lens contamination, ensuring that the operator can clearly observe the working environment, and providing strong guarantees for the smooth progress of the demolition work. At the same time, continuous blowing can also accelerate the air flow, and promptly take away the heat generated by the camera and the lighting lamp during operation, so that the equipment is always in a suitable working temperature range, maintaining To maintain its stable performance and extend the service life of the equipment, when the demolition robot is idle for a long time, the first servo motor 203 can be started, and the output shaft of the first servo motor 203 rotates to drive the installation shaft 201 to rotate synchronously, and the installation shaft 201 then drives the protective cover 202 to rotate. When the protective cover 202 rotates to a certain position, it will completely cover the camera and the lighting, providing reliable protection for the equipment. During the idle period of the robot, it can effectively prevent dust from falling onto the equipment, preventing dust from damaging the equipment or affecting the normal use of the equipment next time. In addition, the protective cover 202 The filter 205 on 02 has good ventilation performance. Even when the protective cover 202 covers the equipment, it can maintain air circulation to prevent moisture or excessive temperature inside the equipment due to poor air circulation, further protecting the performance and service life of the equipment. During the rotation of the protective cover 202, it will drive the gear 305 to move until the gear 305 is engaged with the rack 207. At this time, the gear 305 starts to rotate and drives the connecting shaft 301 to rotate. During the rotation of the connecting shaft 301, the torsion spring 304 is deformed to store elastic potential energy for the subsequent connecting shaft 301 is reversed, and the connecting shaft 301 continues to drive the installation frame 302 to rotate, and the installation frame 302 then drives the axial flow fan 303 to rotate. When the protective cover 202 is rotated into place, the installation frame 302 is rotated exactly one hundred and eighty degrees. At this time, the axial flow fan 303 starts blowing. The wind blown by the axial flow fan 303 can blow away the dust on the filter 205, avoid dust accumulation on the filter 205, and prevent the ventilation and heat dissipation effects from being affected by the blockage of the filter 205, thereby ensuring the continued effectiveness of the ventilation and heat dissipation functions of the protective cover 202 and further enhancing the protection of the camera and the lighting.
