Description

Technical Field

[0001] This utility model belongs to the technical field of obstacle crossing transport vehicles, specifically relating to a freewheel type obstacle crossing transport vehicle. Background Technology

[0002] The freewheel off-road transport vehicle is designed for situations where rescue channels are damaged or blocked during natural disasters (earthquakes, mudslides, landslides, etc.) or highway rescues. This vehicle uses a new freewheel structure, which can overcome the difficulty of large vehicles not being able to reach the rescue site, effectively cope with complex road conditions, effectively solve the last-mile problem of transporting rescue equipment, and has the advantage of being able to follow the operators to the mission site without the need for remote operation, freeing up their hands.

[0003] Existing freewheel obstacle-crossing vehicles are prone to encountering obstacles during actual operation, requiring users to frequently use wireless control to steer them. This makes the operation of the obstacle-crossing vehicle inconvenient and affects its ease of use, thus making the device less usable.

[0004] Therefore, there is a need for a freewheel obstacle crossing vehicle to solve the problem that existing freewheel obstacle crossing vehicles are prone to encountering obstacles during actual driving, requiring users to frequently use wireless control to steer the vehicle, which makes the operation of the obstacle crossing vehicle somewhat inconvenient. Utility Model Content

[0005] The purpose of this invention is to provide a freewheeled obstacle-crossing transport vehicle to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a freewheeled obstacle-crossing transport vehicle, comprising an obstacle-crossing transport vehicle body, two fixed seats fixed to one side of the surface of the obstacle-crossing transport vehicle body, a connecting seat provided on one side of the fixed seats, two scrapers provided on one side of the connecting seats, a rotating shaft rotatably connected to both sides of the top surface of the connecting seat, an L-shaped support seat fixedly sleeved at the middle position of the outer circumference of the rotating shaft, the bottom of the support seat being fixed to the top surface of the adjacent scraper, a first motor fixed at the middle position of the top surface of the connecting seat, and a first motor having a top of the first motor... A receiving shaft is provided, and support platforms are fixed on the top surface of the connecting seat at positions on both sides of the first motor. The two support platforms are rotatably connected to the receiving shaft. Three first bevel gears are fixedly sleeved on the outer circumferential surface of the receiving shaft. A second bevel gear is fixedly sleeved on the top of the outer circumferential surface of the rotating shaft. A third bevel gear is fixedly sleeved on the outer circumferential surface of the output end of the first motor. The second bevel gear is meshed with the first bevel gear at an adjacent position. The third bevel gear is meshed with the first bevel gear at an adjacent position. An observer is installed on one side of the fixed seat.

[0007] It should be noted in the solution that a movable shaft is rotatably connected at the middle position of the fixed base, and a sleeve is fixedly fitted at the middle position of the outer circumference of the movable shaft, with one side of the sleeve fixed to the surface of the connecting base.

[0008] It is worth noting that the two ends of the outer circumference of the movable shaft are fixedly fitted with spur gears, and racks are meshed on one side of the two spur gears. Threaded seats are fixed to the top of the two racks.

[0009] Furthermore, it should be noted that a second motor is fixed to one side of the obstacle-crossing transport vehicle body, and a threaded rod is threadedly connected through the middle position of the threaded seat. The top of the threaded rod passes through the obstacle-crossing transport vehicle body and is fixed to the output end of the second motor.

[0010] In a preferred embodiment, the threaded seat has two abutment grooves on the surface of the side near the obstacle crossing vehicle body, and an abutment strip is inserted through the interior of the abutment groove. The surface of the abutment strip near the obstacle crossing vehicle body is fixed to the surface of the obstacle crossing vehicle body.

[0011] In a preferred embodiment, the diameter of the bottom of the outer circumferential surface of the threaded rod is larger than that of the top of its outer circumferential surface, and the diameter of the bottom of the outer circumferential surface of the threaded rod is larger than the diameter of the hole in the inner wall of the threaded seat.

[0012] Compared with the prior art, the freewheeled obstacle-crossing transport vehicle provided by this utility model has at least the following beneficial effects:

[0013] (1) The observer observes whether there are obstacles in the direction of travel of the obstacle crossing vehicle. The first motor is started to make the receiving shaft rotate, so that the rotating shaft can drive the scraper to change the angle to the side of the obstacle crossing vehicle. This allows the scraper to push the obstacle away from the direction of travel of the obstacle crossing vehicle, so that the user does not need to frequently operate the obstacle crossing vehicle to turn, thereby improving the ease of use of the obstacle crossing vehicle and improving the practicality of the device.

[0014] (2) By starting the second motor, the two racks can move in the vertical direction, thereby causing the movable shaft to drive the connecting seat to change the angle, thereby adjusting the height of the scraper. This allows the user to adjust the scraper according to the actual situation, thus adapting to various uphill, downhill and flat road conditions, thereby improving the applicability of the device.

[0020] Please see Figure 1-4This utility model provides a freewheeled obstacle-crossing transport vehicle, including an obstacle-crossing transport vehicle body 1. Two fixed seats 2 are fixed on one side of the surface of the obstacle-crossing transport vehicle body 1. A connecting seat 5 is provided on one side of the fixed seat 2. Two scrapers 6 are provided on one side of the connecting seat 5. A rotating shaft 7 is rotatably connected to both sides of the top surface of the connecting seat 5. An L-shaped support seat 8 is fixedly sleeved at the middle position of the outer circumference of the rotating shaft 7. The bottom of the support seat 8 is fixed to the top surface of the adjacent scraper 6. A first motor 9 is fixed at the middle position of the top surface of the connecting seat 5. A receiving shaft 11 is provided on the top of the first motor 9. Support platforms 10 are fixed on the top surface of the connecting seat 5 at the positions on both sides of the first motor 9. The two support platforms 10 are rotatably connected to the receiving shaft 11. Three first bevel gears 12 are fixedly sleeved on the outer circumference of the receiving shaft 11. A second bevel gear 13 is fixedly sleeved on the top of the surface, and a third bevel gear 14 is fixedly sleeved on the outer circumferential surface of the output end of the first motor 9. The second bevel gear 13 is meshed with the adjacent first bevel gear 12, and the third bevel gear 14 is meshed with the adjacent first bevel gear 12. An observer 22 is installed on one side of the fixed base 2. The observer 22 observes whether there are obstacles in the direction of travel of the obstacle crossing vehicle body 1. By starting the first motor 9, the receiving shaft 11 can be rotated, so that the rotating shaft 7 can drive the scraper 6 to change angle to the side of the obstacle crossing vehicle body 1. This allows the scraper 6 to push the obstacle away from the direction of travel of the obstacle crossing vehicle body 1, so that the user does not need to frequently operate the obstacle crossing vehicle to turn, thereby improving the ease of use of the obstacle crossing vehicle.

[0021] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that a movable shaft 3 is rotatably connected at the middle position of the fixed base 2, and a sleeve 4 is fixedly fitted at the middle position of the outer circumference of the movable shaft 3. One side of the sleeve 4 is fixed to the surface of the connecting base 5. Since the movable shaft 3 can rotate, the sleeve 4 can drive the connecting base 5 to change its angle, thereby allowing the connecting base 5 to change its angle so that the scraper 6 can be adjusted to adapt to various uphill, downhill and flat road conditions, thus improving the applicability of the device.

[0022] Further as Figure 1 and Figure 2As shown, it is worth noting that two spur gears 17 are fixedly sleeved at both ends of the outer circumference of the movable shaft 3. A rack 18 is meshed on one side of the two spur gears 17. A threaded seat 19 is fixed to the top of the two racks 18. A second motor 15 is fixed to one side of the obstacle crossing vehicle body 1. A threaded rod 16 is threaded through the middle of the threaded seat 19. The top of the threaded rod 16 passes through the obstacle crossing vehicle body 1 and is fixed to the output end of the second motor 15. Two abutment grooves 21 are formed on the surface of the threaded seat 19 near the obstacle crossing vehicle body 1. An abutment strip is inserted through the inside of the abutment grooves 21. 20. The surface of the contact bar 20 near the obstacle crossing vehicle body 1 is fixed to the surface of the obstacle crossing vehicle body 1. Due to the contact action between the contact bar 20 and the contact groove 21, the threaded seat 19 can move in the vertical direction, so that the threaded rod 16 can rotate when the second motor 15 is started. Thus, the rack 18 can move in the vertical direction under the cooperation between the internal thread structure on the inner wall of the threaded seat 19 and the external thread structure on the outer circumference of the threaded rod 16. Thus, the movable shaft 3 can rotate under the meshing action between the rack 18 and the spur gear 17.

[0023] This solution has the following working process: In actual use, when the obstacle-crossing transport vehicle 1 encounters an obstacle during operation, the height and angle of the scraper 6 are adjusted according to the road conditions traveled by the obstacle-crossing transport vehicle 1. Due to the contact action between the contact strip 20 and the contact groove 21, the threaded seat 19 can only move in the vertical direction. When the second motor 15 is started, the threaded rod 16 can rotate. Thus, under the cooperation between the internal thread structure on the inner wall of the threaded seat 19 and the external thread structure on the outer circumference of the threaded rod 16, the rack 18 can move in the vertical direction. Thus, under the meshing action between the rack 18 and the spur gear 17, the movable shaft 3 can rotate, thereby driving the sleeve 4 to rotate to adjust the height angle between the connecting seat 5 and the scraper 6. The system adjusts to the road conditions on which the obstacle crossing vehicle 1 travels. Then, the first motor 9 is started, causing the third bevel gear 14 to rotate. This allows the receiving shaft 11 to rotate due to the meshing between the third bevel gear 14 and one of the first bevel gears 12. This, in turn, drives the remaining two first bevel gears 12 to rotate. This, in turn, allows the rotating shaft 7 to rotate due to the meshing between the first bevel gear 12 and the second bevel gear 13. The two rotating shafts 7 rotate in opposite directions, allowing the two scrapers 6 to push the obstacle away from the obstacle crossing vehicle 1 under the drive of the support seat 8. This eliminates the need for the user to frequently operate the obstacle crossing vehicle to steer, thus improving the ease of use of the obstacle crossing vehicle.

[0024] According to the above working process: the observer 22 observes whether there are obstacles in the direction of travel of the obstacle crossing vehicle 1, and the first motor 9 is started to make the receiving shaft 11 rotate, so that the rotating shaft 7 can drive the scraper 6 to change the angle to the side of the obstacle crossing vehicle 1, so that the scraper 6 can push the obstacle away from the direction of travel of the obstacle crossing vehicle 1. Therefore, the user does not need to frequently operate the obstacle crossing vehicle to turn, thus improving the ease of use of the obstacle crossing vehicle and improving the practicality of the device. The second motor 15 is started to make the two racks 18 move in the vertical direction, so that the movable shaft 3 can drive the connecting seat 5 to change the angle, thereby adjusting the height of the scraper 6. This allows the user to adjust the scraper 6 according to the actual situation, thus adapting to various uphill, downhill and flat road conditions, thereby improving the applicability of the device.

[0025] Further as Figure 1 As shown, it is worth noting that the diameter of the bottom of the outer peripheral surface of the threaded rod 16 is larger than that of the top of its outer peripheral surface, and the diameter of the bottom of the outer peripheral surface of the threaded rod 16 is larger than the diameter of the hole in the inner wall of the threaded seat 19. Due to the shape of the threaded rod 16, the threaded seat 19 can be prevented from separating from the outer peripheral surface of the threaded rod 16 by the contact action between the bottom of the outer peripheral surface of the threaded rod 16 and the surface of the threaded seat 19.

[0026] In summary: The observer 22 monitors whether there are obstacles in the direction of travel of the obstacle crossing vehicle 1. By starting the first motor 9, the receiving shaft 11 can be rotated, which in turn causes the rotating shaft 7 to drive the scraper 6 to change angle to the side of the obstacle crossing vehicle 1. This allows the scraper 6 to push the obstacle away from the direction of travel of the obstacle crossing vehicle 1, thus eliminating the need for the user to frequently operate the obstacle crossing vehicle to turn, thereby improving the ease of use of the obstacle crossing vehicle and enhancing the practicality of the device. By starting the second motor 15, the two racks 18 can move vertically, which causes the movable shaft 3 to drive the connecting seat 5 to change angle, thereby adjusting the height of the scraper 6. This allows the user to adjust the scraper 6 according to the actual situation, making it suitable for various uphill, downhill, and flat road conditions, thus improving the applicability of the device. Due to the shape of the threaded rod 16, the bottom of the outer peripheral surface of the threaded rod 16 can be prevented from detaching from the outer peripheral surface of the threaded seat 19 by the contact action between the bottom of the outer peripheral surface of the threaded rod 16 and the surface of the threaded seat 19.

[0027] The first motor 9, the second motor 15, and the observer 22 can be purchased from the market. The first motor 9, the second motor 15, and the observer 22 are equipped with power supplies. This is a mature technology in the field and has been fully disclosed. Therefore, it will not be repeated in the specification.
