A radar installation structure for driverless mining trucks

Abstract

The present invention discloses a radar installation structure for driverless mining vehicles, including a bottom plate, and through holes for installing the bottom plate are provided at the four corners of the surface of the bottom plate. After an external impact acts on the top surface of the protective frame in the present invention, the protective frame moves downward, thereby driving the top of the first rotating plate to move downward. The downward movement of the protective frame causes the first rotating plate to rotate. The rotation of the first rotating plate uses the top sleeve to push the rotating rod and the inner ring to move inside the limiting frame. At this time, the two opposite inner rings gradually approach inside the limiting frame. The inner ring drives the first clamping plate to move inside the strip groove. The two first clamping plates gradually approach during the movement, and the two first clamping plates clamp the rubber block during the approaching process. By using the clamping of the two first clamping plates and the limitation of the rubber block on the radar, the stability of the radar on the top surface of the bottom plate is further improved, avoiding the wanton shaking of the radar on the top surface of the bottom plate under the action of impact force, and improving the protection of the radar.

The driving environment of autonomous mining vehicles is complex, the road surface is uneven, the dust is large, and sand and stones often fall. The falling sand and stones are likely to directly impact the surface of the radar, causing trauma to the radar, and the impact force brought by the sand and stones will also cause the radar to shift.

[0003] Therefore, it is necessary to invent a radar installation structure for driverless mining vehicles to solve the above problems. Summary of the Invention

The protective frame is correspondingly connected to the top of the buffer structure, and the buffer structure and the two limiting frames are correspondingly buckled on the side of the radar.

[0006] Further, the buffer structure includes four inner rings. The four inner rings are correspondingly located at both ends inside the two limiting frames.

A strip groove slidably matched with the first clamping plate is provided at the center of each of the two limiting frames. Rubber blocks are arranged on both sides of the radar, and the two first clamping plates are correspondingly attached to the two side faces of the radar by the two rubber blocks.

[0007] Further, a limiting rod is fixedly installed at the center of the top surface of the first clamping plate. A sleeve correspondingly matched with the limiting rod is arranged on the bottom surface of the protective frame. And the bottom surface of the protective frame is correspondingly sleeved on the top end of the limiting rod by the sleeve. The bottom end of the sleeve is fixedly connected to the top end of a first spring, and the first spring is sleeved on the surface of the limiting rod. The bottom surface of the first spring is attached to the top surface of the first clamping plate.

[0008] Further, the inner ring is sleeved inside the bottom end of the rotating rod, the top end of the rotating rod is rotatably sleeved with a top sleeve, baffles are arranged on the front and rear sides of the protection frame, and the two baffles are fixedly connected by two connecting rods. The two ends of the connecting rod are respectively correspondingly matched with the adjacent two top sleeves, and the top sleeve and the end of the connecting rod are rotatably connected by a first rotating plate. The opposite two top sleeves are movably connected to the bottoms of the opposite two first rotating plates, and the distance between the bottoms of the opposite two first rotating plates is less than the distance between their tops.

[0009] Further, convex plates are fixedly connected to the tops of the inner sides of the two ends of the first clamping plate, and an elastic plate is fixedly connected between the opposite two convex plates, and the elastic plate is inside the limiting frame.

[0010] Further, movable plates are arranged on the front and rear sides of the bottom plate, and the two movable plates are parallel to the front and rear side faces of the bottom plate. On both sides of the center of the top surface of the movable plate, vertical rods are fixedly installed, and the two vertical rods are respectively correspondingly matched with the opposite two convex plates. The vertical rod and the bottom surface of the convex plate are rotatably connected by a second rotating plate. The distance between the outer ends of the two second rotating plates is less than the distance between their inner ends.

[0011] Further, one-way rotating shafts are connected to the surface of the rotating rod, and the rotating directions of the opposite two one-way rotating shafts are opposite. Second clamping plates are movably installed on the top surfaces of the front and rear ends of the bottom plate. Tooth teeth are arranged on the inner side of the top of the second clamping plate and on the circumferential side of the one-way rotating shaft, and the one-way rotating shaft is meshed with the tooth teeth of the second clamping plate by the tooth teeth.

[0012] Further, sliding grooves corresponding to the bottoms of the two ends of the second clamping plate are arranged on the top surface of the bottom plate. The outer sides of the two ends of the second clamping plate respectively penetrate through the sliding grooves by movable rods, and the outer sides of the two ends of the second clamping plate are fixedly connected to the inner sides of the two ends of the movable plate by the movable rods. A second spring is sleeved on the surface of the movable rod. The second spring is inside the sliding groove, and the second clamping plate is fixedly connected to the inner side surface of the sliding groove by the second spring.

[0013] Technical effects and advantages of the present invention:

[0014] 1. After an external impact acts on the top surface of the protection frame in the present invention, the protection frame moves downward, thereby driving the top of the first rotating plate to move downward. The downward movement of the protection frame causes the first rotating plate to rotate. The rotation of the first rotating plate uses the top sleeve to push the rotating rod and the inner ring to move inside the limiting frame. At this time, the opposite two inner rings gradually approach inside the limiting frame. The inner ring drives the first clamping plate to move inside the strip groove. The two first clamping plates gradually approach during the movement, and the two first clamping plates clamp the rubber block during the approaching process. By the clamping of the two first clamping plates and the limitation of the rubber block on the radar, the stability of the radar on the top surface of the bottom plate is further improved, avoiding the wanton shaking of the radar on the top surface of the bottom plate under the action of the impact force, and improving the protection of the radar.

[0015] 2. When the two convex plates approach each other in the present invention, the bottom end of the convex plate drives the inner end of the second rotating plate to move. The inner ends of the two second rotating plates gradually approach during the movement of the convex plate. At this time, the two second rotating plates rotate to push the movable plate away from the bottom plate by means of the vertical rod. During the movement of the movable plate, the stones around the bottom plate are pushed, so that the front and rear sides of the bottom plate are kept clean and tidy, avoiding the collision between the falling stones and the stones on the front and rear sides of the bottom plate, preventing the fragmented stones from impacting on the front and rear sides of the radar under the action of the impact force, and further improving the protection of the radar.

[0016] 3. When the inner ring drives the rotating rod to move in the present invention, at this time, the two rotating rods gradually approach inside the limiting frame. Since the teeth of the one-way rotating shaft are meshed and matched with the teeth of the second clamping plate, the one-way rotating shaft rotates on the top of the inner side of the second clamping plate during the movement of the rotating rod, and the two opposite one-way rotating shafts rotate in opposite directions. When there is no external force to continue to impact the protection frame, at this time, the two one-way rotating shafts cannot rotate in the reverse direction, that is, the two one-way rotating shafts cannot be separated. At this time, the buckle of the one-way rotating shaft and the second clamping plate acts on the two first clamping plates through the inner ring. At this time, the two first clamping plates clamp the radar through the rubber blocks, ensuring the stability of the radar between the two first clamping plates.

[0017] 4. After the acting force on the protection frame disappears in the present invention, at this time, the first spring, the elastic plate and the second spring rebound, the two one-way rotating shafts gradually move away, the second clamping plate gradually approaches the one-way rotating shaft, and the protection frame also rises under the drive of the elastic force. The stones on the top surface of the protection frame are lifted by the force of the rapid rise of the protection frame, which is convenient for cleaning the stones on the top surface of the protection frame, avoiding too many broken stones on the top surface of the protection frame. Too many broken stones will cause the protection frame to move downward, thereby reducing the descending distance of the protection frame and ensuring the sufficiency of the elastic force of the first spring, the elastic plate and the second spring.

Specific embodiments

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] The present invention provides a radar installation structure for an unmanned mining vehicle, as Figure 1-2As shown in the figure, it includes a bottom plate 1. Through holes for installing the bottom plate 1 are provided at the four corners of the surface of the bottom plate 1. A radar 2 is correspondingly arranged at the center of the top surface of the bottom plate 1. Two limiting frames 3 are correspondingly arranged in parallel on the top surface of the bottom plate 1. The inner sides of the two limiting frames 3 are correspondingly attached to the front and rear side faces of the radar 2. A buffer structure for protecting the radar 2 is arranged at the top inner part of the two limiting frames 3. And a protective frame 4 is arranged on the top surface of the bottom plate 1. The protective frame 4 is correspondingly connected to the top of the buffer structure, and the buffer structure and the two limiting frames 3 are correspondingly buckled on the side of the radar 2. When the radar 2 needs to be installed, the orientation of the radar 2 is adjusted according to the specific size of the radar 2, so that the distance between the front and rear sides of the radar 2 can correspond to the distance between the inner sides of the two limiting frames 3, which is convenient for the radar 2 to be correspondingly placed on the top surface of the bottom plate 1 between the two limiting frames 3. After the radar 2 is correspondingly placed, a plurality of bolts are used to penetrate the through holes of the bottom plate 1 to correspondingly install the bottom plate 1 on the top of the mine car, avoiding the separation of the bottom plate 1 from the mine car. The buffer structure is used to correspondingly place the protective frame 4 on the top surface of the bottom plate 1, and the protective frame 4 is used to correspondingly protect the radar 2, avoiding stones hitting the surface of the radar 2 when the mine car is working, and improving the protection effect on the radar 2.

[0027] When stones fall on the protective frame 4, the protective frame 4 itself is used to prevent the stones from contacting the radar 2. And after the impact force carried by the stones falling on the top surface of the protective frame 4 acts on the protective frame 4, the buffer structure is used to reduce the impact force borne by the protective frame 4, avoiding the impact force acting on the surface of the radar 2.

[0028] In Figure 3 and Figure 4 Among them, the buffer structure includes four inner rings 5. The four inner rings 5 are correspondingly located at both ends of the inner sides of the two limiting frames 3. Adjacent two inner rings 5 are correspondingly connected by a first clamping plate 6. A strip groove 7 that is slidably matched with the first clamping plate 6 is arranged at the center of each of the two limiting frames 3. Rubber blocks 8 are arranged on both sides of the radar 2, and the two first clamping plates 6 are correspondingly attached to the two side faces of the radar 2 by the two rubber blocks 8. When limiting the radar 2, after the radar 2 is correspondingly placed between the two limiting frames 3, at this time, a suitable rubber block 8 is selected according to the distance between the two first clamping plates 6 and the two side faces of the radar 2, and the two rubber blocks 8 are correspondingly placed on both sides of the radar 2. Adjacent two inner rings 5 correspondingly limit the two ends of the first clamping plate 6, and the inner ring 5 is located at the inner end of the limiting frame 3. At this time, the two first clamping plates 6 can use the rubber blocks 8 to limit the radar 2 under the limitation of the inner ring 5 and the limiting frame 3, ensuring the stability of the radar 2 on the top of the bottom plate 1.

[0029] In Figures 2-4In it, a limiting rod 9 is fixedly installed at the center of the top surface of the first clamping plate 6. A sleeve 10 corresponding to the limiting rod 9 is arranged on the bottom surface of the protective frame 4. The bottom surface of the protective frame 4 is correspondingly sleeved on the top end of the limiting rod 9 by means of the sleeve 10. The bottom end of the sleeve 10 is fixedly connected to the top end of a first spring 11, and the first spring 11 is sleeved on the surface of the limiting rod 9. The bottom surface of the first spring 11 is in contact with the top surface of the first clamping plate 6. After the protective frame 4 is correspondingly placed on the top surface of the bottom plate 1, the adhesion effect between the bottom end of the first spring 11 and the top surface of the first clamping plate 6 is improved by using glue. After the protective frame 4 is placed on the top surface of the bottom plate 1, when an external stone impacts on the protective frame 4, at this time, the protective frame 4 moves downward under the action of the impact force. While the protective frame 4 gradually approaches the bottom plate 1, the first spring 11 is compressed by the cooperation of the sleeve 10 and the limiting rod 9. The impact force of the protective frame 4 is absorbed by the elastic force of the first spring 11, so as to prevent the impact force of the protective frame 4 from directly acting on the top surface of the bottom plate 1, thereby improving the protection performance of the protective frame 4 for the radar 2 and preventing an external impact force from directly acting on the surface of the radar 2.

[0030] In Figure 2 and Figure 3 In it, the inner ring 5 is sleeved inside the bottom end of the rotating rod 12. The top end of the rotating rod 12 is rotatably sleeved with a top sleeve 13. Baffles 14 are arranged on the front and rear side surfaces of the protective frame 4. Two connecting rods 15 are fixedly connected between the inner side surfaces of the two baffles 14. The two ends of the connecting rod 15 respectively correspond to and cooperate with the adjacent two top sleeves 13. The top sleeve 13 and the end of the connecting rod 15 are rotatably connected by means of a first rotating plate 16. The opposite two top sleeves 13 are movably connected to the bottoms of the opposite two first rotating plates 16. The distance between the bottoms of the opposite two first rotating plates 16 is less than the distance between their tops. After the inner ring 5 is correspondingly placed inside the limiting frame 3, the adjacent two inner rings 5 are correspondingly connected by means of the first clamping plate 6. The sliding fit between the first clamping plate 6 and the strip groove 7 can ensure the connection effect between the inner ring 5 and the limiting frame 3 and prevent the inner ring 5 from separating from the inside of the limiting frame 3. The inner ring 5 is movably sleeved on the bottom end of the rotating rod 12, which can prevent the rotating rod 12 from separating from the inside of the inner ring 5. After an external impact acts on the top surface of the protective frame 4, the protective frame 4 moves downward, thereby driving the top of the first rotating plate 16 to move downward. Due to the limitation of the top of the first rotating plate 16 by the connecting rod 15 on the protective frame 4 itself, the downward movement of the protective frame 4 causes the first rotating plate 16 to rotate. The rotation of the first rotating plate 16 uses the top sleeve 13 to push the rotating rod 12 and the inner ring 5 to move inside the limiting frame 3. At this time, the opposite two inner rings 5 gradually approach inside the limiting frame 3.

[0031] In Figure 3 and Figure 4Among them, convex plates 17 are fixedly connected to the tops of the inner sides of both ends of the first clamping plate 6. An elastic plate 18 is fixedly connected between two opposite convex plates 17, and the elastic plate 18 is located inside the limiting frame 3. When the two inner rings 5 gradually approach inside the limiting frame 3, at this time, the inner ring 5 drives the first clamping plate 6 to move inside the strip groove 7. The two first clamping plates 6 gradually approach during the movement, and the two first clamping plates 6 clamp the rubber block 8 during the approaching process. By using the clamping of the two first clamping plates 6 and the limitation of the rubber block 8 on the radar 2, the stability of the radar 2 on the top surface of the bottom plate 1 is further improved, avoiding the wanton shaking of the radar 2 on the top surface of the bottom plate 1 under the action of impact force, and improving the protection of the radar 2. When the two first clamping plates 6 approach each other, the first clamping plate 6 drives the convex plate 17 to move synchronously, that is, when the two opposite convex plates 17 approach each other, the elastic plate 18 is squeezed. By using the elastic force of the elastic plate 18, the impact force of the downward movement of the protective frame 4 can be further reduced.

[0032] In Figures 1-3 Among them, movable plates 19 are arranged on the front and rear sides of the bottom plate 1, and the two movable plates 19 are parallel to the front and rear side faces of the bottom plate 1 correspondingly. On both sides of the center of the top surface of the movable plate 19, vertical rods 20 are fixedly installed, and the two vertical rods 20 are correspondingly matched with two opposite convex plates 17 respectively. The bottom surfaces of the vertical rods 20 and the convex plates 17 are rotatably connected by second rotating plates 21. The distance between the outer ends of the two second rotating plates 21 is less than the distance between their inner ends. When the two convex plates 17 approach each other, the bottom ends of the convex plates 17 drive the inner ends of the second rotating plates 21 to move. The inner ends of the two second rotating plates 21 gradually approach during the movement of the convex plates 17. At this time, the two second rotating plates 21 rotate to push the movable plate 19 to gradually move away from the bottom plate 1 by using the vertical rods 20. The movable plate 19 pushes the stones around the bottom plate 1 during the movement, so that the front and rear sides of the bottom plate 1 are kept clean and tidy, avoiding the collision between the fallen stones and the stones on the front and rear sides of the bottom plate 1, and preventing the broken stones from impacting the front and rear side faces of the radar 2 under the action of impact force, further improving the protection of the radar 2.

[0033] In Figures 1-3In it, a one-way rotating shaft 22 is connected to the surface of the rotating rod 12. The rotating directions of two opposite one-way rotating shafts 22 are opposite. Second clamping plates 23 are movably installed on the top surfaces of the front and rear ends of the bottom plate 1. Tooth teeth are provided on the inner side surfaces of the tops of the second clamping plates 23 and on the circumferential sides of the one-way rotating shafts 22. And the one-way rotating shaft 22 is meshed and matched with the tooth teeth of the second clamping plate 23 by means of the tooth teeth. A sliding groove corresponding to the bottom of both ends of the second clamping plate 23 is arranged on the top surface of the bottom plate 1. Outer side surfaces of both ends of the second clamping plate 23 penetrate through the sliding groove by means of movable rods 24. And outer side surfaces of both ends of the second clamping plate 23 are fixedly connected to inner side surfaces of both ends of a movable plate 19 by means of the movable rods 24. A second spring 25 is sleeved on the surface of the movable rod 24. The second spring 25 is located inside the sliding groove. And the second clamping plate 23 is fixedly connected to the inner side surface of the sliding groove by means of the second spring 25. When the inner ring 5 drives the rotating rod 12 to move, at this time the two rotating rods 12 gradually approach inside the limiting frame 3. Due to the meshing and matching of the tooth teeth of the one-way rotating shaft 22 and the tooth teeth of the second clamping plate 23, the one-way rotating shaft 22 rotates on the top inner side surface of the second clamping plate 23 during the movement of the rotating rod 12. And the rotating directions of two opposite one-way rotating shafts 22 are opposite. When there is no external force to continue to impact the protective frame 4, at this time the two one-way rotating shafts 22 cannot rotate in the reverse direction, that is, the two one-way rotating shafts 22 cannot be separated. At this time, the buckles of the one-way rotating shaft 22 and the second clamping plate 23 act on the two first clamping plates 6 through the inner ring 5. At this time, the two first clamping plates 6 clamp the radar 2 through the rubber blocks 8, ensuring the stability of the radar 2 between the two first clamping plates 6.

[0034] When the two convex plates 17 approach each other, at this time the two convex plates 17 drive the inner ends of the two second rotating plates 21 to gradually approach. The second rotating plates 21 rotate and then push the movable plate 19 to gradually move away from the bottom plate 1. When the movable plate 19 moves away from the bottom plate 1, at this time the movable plate 19 pulls the second clamping plate 23 by means of the movable rod 24. The second clamping plate 23 moves synchronously with the movable plate 19. And when the second clamping plate 23 moves inside the sliding groove, it compresses the second spring 25. The elastic force of the second spring 25 can further absorb the impact force absorbed by the protective frame 4. When the second clamping plate 23 moves away from the one-way rotating shaft 22, at this time the two rotating rods 12 cannot rotate. The elastic forces of the first spring 11, the elastic plate 18 and the second spring 25 are used to prevent the impact force of the gravel from directly acting on the radar 2, improving the protection of the radar 2.

[0035] After the force acting on the protection frame 4 disappears, the first spring 11, the elastic plate 18 and the second spring 25 rebound at this time. The two one-way rotating shafts 22 gradually move away from each other, and the second clamping plate 23 gradually approaches the one-way rotating shaft 22. Moreover, the protection frame 4 also rises under the drive of the elastic force. The stones on the top surface of the protection frame 4 are lifted by the force of the rapid rise of the protection frame 4, which facilitates the cleaning of the stones on the top surface of the protection frame 4 and avoids excessive gravel on the top surface of the protection frame 4. Excessive gravel will cause the protection frame 4 to move downward, thereby reducing the distance of the downward movement of the protection frame 4 and ensuring the sufficiency of the elastic force of the first spring 11, the elastic plate 18 and the second spring 25.

[0036] The working principle of the present invention:

[0037] Refer to the attached Figures 1-4 According to the specific size of the radar 2, the orientation of the radar 2 is adjusted so that the distance between the front and rear sides of the radar 2 can correspond to the distance between the inner sides of the two limiting frames 3, which facilitates the radar 2 to be correspondingly placed on the top surface of the bottom plate 1 between the two limiting frames 3. After the radar 2 is correspondingly placed, a plurality of bolts are used to penetrate the through holes of the bottom plate 1 to correspondingly install the bottom plate 1 on the top of the mine car, avoiding the separation of the bottom plate 1 from the mine car.

[0038] After an external impact acts on the top surface of the protection frame 4, the protection frame 4 moves downward and then drives the top of the first rotating plate 16 to move downward. Since the protection frame 4 itself limits the top end of the first rotating plate 16 by means of the connecting rod 15, the downward movement of the protection frame 4 causes the first rotating plate 16 to rotate. The rotation of the first rotating plate 16 uses the top sleeve 13 to push the rotating rod 12 and the inner ring 5 to move inside the limiting frame 3. At this time, the two opposite inner rings 5 gradually approach each other inside the limiting frame 3, and the inner ring 5 drives the first clamping plate 6 to move inside the strip groove 7. The two first clamping plates 6 gradually approach each other during the movement, and the two first clamping plates 6 clamp the rubber block 8 during the approaching process. By using the clamping of the two first clamping plates 6 and the limitation of the rubber block 8 on the radar 2, the stability of the radar 2 on the top surface of the bottom plate 1 is further improved, avoiding the wanton shaking of the radar 2 on the top surface of the bottom plate 1 under the action of the impact force, and improving the protection of the radar 2. When the two first clamping plates 6 approach each other, the first clamping plate 6 drives the convex plate 17 to move synchronously, that is, the two opposite convex plates 17 squeeze the elastic plate 18 during the approaching process. The elastic force of the elastic plate 18 can further reduce the impact force of the downward movement of the protection frame 4.

[0039] When the two convex plates 17 approach each other, the inner ends of the two second rotating plates 21 are gradually driven to approach by the two convex plates 17. The second rotating plates 21 rotate and then push the movable plate 19 to gradually move away from the bottom plate 1. When the movable plate 19 moves away from the bottom plate 1, the movable plate 19 uses the movable rod 24 to pull the second clamping plate 23 at this time. The second clamping plate 23 moves synchronously with the movable plate 19, and the second clamping plate 23 squeezes the second spring 25 when moving inside the chute. The elastic force of the second spring 25 can further absorb the impact force absorbed by the protection frame 4. When the second clamping plate 23 moves away from the one-way rotating shaft 22, the two rotating rods 12 cannot rotate at this time. The elastic forces of the first spring 11, the elastic plate 18 and the second spring 25 are used to prevent the impact force of the stone from directly acting on the radar 2, thereby improving the protection of the radar 2.
