Description

Technical Field

[0001] The invention belongs to the technical field of tracked vehicles, and in particular relates to a floating system of an amphibious emergency rescue tracked vehicle. Background Art

[0002] Tracked vehicles can also use the tracks to paddle forward. When the tracks rotate in the water, the lower track paddles to generate thrust. The upper track and fender form a waterway. The fender is low in the front and high in the back. The rear fender has a guide water fence. When the lower track rotates, the water flow driven by it passes through the water fence and also generates thrust. Although the upper track paddles to generate resistance, it is much smaller than the thrust generated by the lower track and the water fence, allowing the tracked vehicle to travel on the water. The steering and reversing operations of tracked vehicles propelled by paddling in the water are the same as those of tracked vehicles traveling on land. However, in order to make the track vehicle have better driving ability on land, the thickness of the track will not be increased, which makes it difficult for the relatively smooth track to generate enough power in the water; and in order to prevent the water flow on the upper side of the track from affecting the thrust generated by the water flow on the lower side of the track, an arc-shaped fender is often set. The water flow at the end of the fender generates a downward thrust, causing the tracked vehicle to float. When the upper track floats to the surface, the thrust of the water flow at the end of the fender disappears, and the tracked vehicle dives again. This causes the tracked vehicle to frequently bump up and down, which is not conducive to the tracked vehicle floating smoothly in the water. Summary of the invention

[0003] In order to solve the above problems existing in the prior art, the present invention aims to provide a floating system for an amphibious rescue tracked vehicle.

[0004] The technical solution adopted by the present invention is:

[0006] In the above technical solution, the emergency rescue tracked vehicle can not only travel on land but also float in water. The floating power relies on paddling by the card board, which has sufficient power and does not require a jet pump to compensate for the power.

[0007] As a preferred embodiment of the present invention, the end of the fender close to the driving wheel is arc-shaped, the end of the fender close to the guide wheel is straight, and a water channel is formed between the fender and the crawler track.

[0018] In the above technical solution, the control disk rotates to guide the ejector rod to move through the arc groove, thereby driving the ejector plate to slide along the slot, which is not easy to get stuck and has a smooth transition.

[0019] As a preferred embodiment of the present invention, a rotating shaft is fixedly provided at one end of the control disk, an end of the rotating shaft away from the control disk is located on the outside of the load-bearing wheel, and a gear is fixedly provided at one end of the rotating shaft located on the outside of the load-bearing wheel, and the gear is meshed with a ring gear of a control system inside the amphibious rescue tracked vehicle.

[0023] In the above technical solution, the gas spring allows the clamping plate that is not in contact with the load-bearing wheel to be retracted into the inner side of the track, so that a large water flow is not formed on the upper side of the track, ensuring that the amphibious rescue tracked vehicle can move forward smoothly in the water.

[0024] As a preferred embodiment of the present invention, a plurality of offset ribs and through holes are provided at one end of the crawler away from the slide groove.

[0040] Combine the following Figure 1-8The specific implementation mode of the present invention is described. In one embodiment of the present invention, a floating system of an amphibious rescue tracked vehicle includes a fender 11 and a track 13.

The amphibious rescue tracked vehicle can not only travel on land, but also float in the water, relying on the tracks to paddle in the water. The water flow on the lower side of the tracks provides power for the amphibious rescue tracked vehicle, and the water flow on the upper side of the tracks is affected by the fenders and has less influence on the movement of the amphibious rescue tracked vehicle.

[0041] In another embodiment of the present invention, the slot 20 is flared, and a plurality of the slots 20 are evenly distributed along the circumference of the load-bearing wheel 18. The diameter of the slot 20 at one end away from the axis of the load-bearing wheel 18 is larger than the diameter of the end close to the axis of the load-bearing wheel 18. A top plate 21 is slidably provided in each of the slots 20. A limiting device is provided at one end of the top plate 21 close to the axis of the load-bearing wheel 18, and the maximum sliding range of the top plate 21 will not exceed the range of the slot 20; the limiting device includes a push rod 27 and a control pin 28, the push rod 27 is fixedly connected to the top plate 21, the control pin 28 is located at one end of the push rod 27 away from the top plate 21, and the control pin 28 is fixedly connected to the push rod 27; the width of the top plate 21 is larger than the width of the card plate 14, and the diameter of the push rod 27 is smaller than the width of the top plate 21; the load-bearing wheel 18 is hollow cylindrical as a whole, and the inner part of the load-bearing wheel 18 is provided with a stopper 27; There is a control disk 22, which is rotatably connected to the control pin 28. The control disk 22 is provided with a plurality of arc grooves 23, which are evenly distributed along the circumference of the control disk 22, the number of the arc grooves 23 is equal to the number of the top plate 21, and the distances from the two ends of the arc grooves 23 to the center of the control disk 22 are not equal; a rotating shaft 25 is fixedly provided at one end of the control disk 22, and the end of the rotating shaft 25 away from the control disk 22 is located on the outside of the load-bearing wheel 18, and a gear 26 is fixedly provided at the end of the rotating shaft 25 located on the outside of the load-bearing wheel 18, and the gear 26 is meshed with the gear ring of the control system inside the amphibious rescue tracked vehicle; a sleeve 24 is provided between the control disk 22 and the gear 26, the sleeve 24 is rotatably connected to the rotating shaft 25, the sleeve 24 is fixedly connected to the top plate 21, and the sleeve 24 is rotatably connected to the outer wall of the amphibious rescue tracked vehicle. The control plate 22 and the top rod 27 cooperate with each other to be equivalent to a cam diameter reducing mechanism, which controls the extension and retraction of the top plate 21. When the top plate 21 is retracted, the card plate 14 can be inserted into the card slot 20. When the top plate 21 is extended, the card plate 14 cannot be inserted into the card slot 20.

The track can be designed to be relatively smooth, relying on the card plate to paddle, and the card plate that does not participate in paddling is retracted into the track, which will not generate a large water flow, so that the water flow in the waterway does not affect the movement of the amphibious rescue tracked vehicle (the water in front of the fender sprays downward and backward, which will cause the amphibious rescue tracked vehicle to swing up and down).

[0042] In another embodiment of the present invention, a slide groove 29 is fixedly provided on each section of the crawler 13, and the slide groove 29 is slidably connected to the clamping plate 14. A gas spring 30 is provided on one side of the clamping plate 14, and one end of the gas spring 30 is fixedly connected to the clamping plate 14, and the other end of the gas spring 30 is fixedly connected to the crawler 13; a plurality of dislocation ribs 31 and through holes are provided on one end of the crawler 13 away from the slide groove 29; an end cover 19 is provided on one side of the load-bearing wheel 18, and the end cover 19 is fixedly connected to the load-bearing wheel 18. Only the clamping plate 14 in contact with the load-bearing wheel 18 on the lower side will extend, and the clamping plate 14 in contact with the towing wheel 12 on the upper side will shrink inside the crawler 13 under the action of the gas spring 30. The part of the crawler 13 in which the clamping plate 14 is in a shrinking state is relatively smooth, and has a small rotation resistance in the water. The water flows slowly through the waterway 15, and will not interfere with the floating of the amphibious rescue crawler vehicle.

[0043] Working principle of the present invention:

[0044] When traveling on land, the gear ring controlled by the control system inside the amphibious rescue tracked vehicle drives the gear 26 to rotate, the gear 26 drives the rotating shaft 25 to rotate, and the control plate 22 rotates along with the rotating shaft 25, and under the action of the top rod 27 and the control pin 28, the top plate 21 is close to the axis of the load-bearing wheel 18; the power system drives the driving wheel 17, and the driving wheel 17 drives the track 13 to rotate, and the amphibious rescue tracked vehicle moves normally on land.

[0045] When floating in the water, the ring gear controlled by the control system inside the amphibious rescue tracked vehicle drives the gear 26 to rotate, the gear 26 drives the rotating shaft 25 to rotate, and the control disk 22 rotates together with the rotating shaft 25. Under the action of the top rod 27 and the control pin 28, the top plate 21 is moved away from the axis of the load-bearing wheel 18; the top plate 21 blocks the slot 20, causing the corresponding card plate 14 at the load-bearing wheel 18 to slide relative to the track 13, and multiple load-bearing wheels 18 cause multiple card plates 14 on the lower track 13 to extend outward from the track 13, providing unidirectional stable power for the amphibious rescue tracked vehicle in the water.
