Specific embodiments

[0054] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0055] The core of the present invention is to provide an amphibious operation engineering vehicle, which is provided with a hydroplane device and an earthmoving device at the same time. When in the water navigation state, the earthmoving device will not generate additional resistance, so that the engineering vehicle has a relatively fast navigation speed; in the earthmoving working state, the earthmoving device extends to the earthmoving state and can perform earthmoving operations.

[0056] Please refer to Figures 1 to 18 .

[0057] This specific embodiment discloses an amphibious operation engineering vehicle, including:

[0058] The main body 1 of the engineering vehicle, on which the earthmoving device 3 and the hydroplane device 2 are installed at the front end of the vehicle head;

[0059] The hydroplane device 2, which can be retracted and folded to fit the surface of the main body 1 of the engineering vehicle or extended and unfolded to the hydroplane state; the hydroplane device 2 is provided with a through groove for accommodating the earthmoving device 3;

[0060] The earthmoving device 3, which can be telescoped to extend to the earthmoving state or folded into the through groove. When it is folded into the through groove, the water-facing surface of the earthmoving device 3 is flush with the outer surface of the hydroplane device 2.

[0061] It should be noted that the water skiing device 2 mentioned in this specific embodiment can be retracted and folded to fit the surface of the engineering vehicle body 1, which means that the water skiing device 2 can be retracted and folded to a position where it fits the outer surface of the engineering vehicle body 1, so as to reduce the space occupied by the water skiing device 2 during transportation.

[0062] Preferably, in order to achieve the lightweight of the amphibious operation engineering vehicle, the components in the water skiing device 2 can be set as hollow structures, which can increase buoyancy while reducing weight.

[0063] It should be noted that the through groove in the water skiing device 2 can be a through hole 212 or a groove with a bottom surface that does not penetrate the water skiing device 2, which is specifically determined according to the actual situation; during the process of storing the bulldozing device 3, when the bulldozing device 3 is stored in the through groove, the water-facing surface of the bulldozing device 3 can just be flush with the outer surface of the water skiing device 2, so as to avoid the bulldozing device 3 protruding from the outer surface of the water skiing device 2. During water navigation, since the bulldozing device 3 will not protrude from the water skiing device 2, no additional resistance will be brought.

[0064] During the use process, no matter whether the water skiing device 2 extends and unfolds to any position or retracts and folds to any position, the bulldozing device 3 can be adjusted to a position where the water-facing surface of the bulldozing device 3 is flush with the outer surface of the water skiing device 2, which is specifically determined according to the actual situation and will not be elaborated here.

[0065] When using the amphibious operation engineering vehicle provided in this specific embodiment, in the transportation state, the water skiing device 2 can be retracted and folded to a position where it fits the surface of the engineering vehicle body 1, and the bulldozing device 3 can be retracted and folded into the through groove to reduce the space occupied and meet the transportation requirements. When the bulldozing device 3 is retracted and folded into the through groove, the bulldozing device 3 can be completely located in the through groove, the water-facing surface of the bulldozing device 3 can be flush with the outer surface of the water skiing device 2, or the water-facing surface of the bulldozing device 3 can have a certain distance from the outer surface of the water skiing device 2; it can also be that the bulldozing device 3 is partially located in the through groove, which is specifically determined according to the actual situation; in the water navigation state, the water skiing device 2 can be extended and unfolded to the water skiing state, and the bulldozing device 3 can be retracted and folded into the through groove and the water-facing surface is flush with the outer surface of the water skiing device 2. When the water skiing device 2 extends and unfolds to the water skiing state, the extension and unfolding angle of the water skiing device 2 can be adjusted. No matter how the angle of the water skiing device 2 is adjusted, the bulldozing device 3 can be retracted and folded into the through groove and the water-facing surface is flush with the outer surface of the water skiing device 2, so as to avoid the bulldozing device 3 generating additional resistance and affecting the navigation speed; in the bulldozing working state, the water skiing device 2 can be retracted and folded to a position where it fits the surface of the engineering vehicle body 1, and the bulldozing device 3 can be extended and unfolded to the bulldozing state for bulldozing work.

[0066] Compared with the prior art, the amphibious operation engineering vehicle provided in this specific embodiment is provided with a hydroplaning device 2 and a bulldozing device 3 at the same time. When in the water navigation state, the bulldozing device 3 will not generate additional resistance. Therefore, the setting of the bulldozing device 3 will not affect the navigation speed of the engineering vehicle, so that the engineering vehicle has a relatively fast navigation speed; in the on-land working state, the bulldozing device 3 extends to the bulldozing state and can perform bulldozing operations, enabling the engineering vehicle to have a bulldozing function. In addition, the actions of the hydroplaning device 2 and the bulldozing device 3 do not affect each other, and the control process is convenient and fast.

[0067] In another specific embodiment, as Figures 1-5 shown, the hydroplaning device 2 includes: a skateboard assembly provided with at least two relatively rotatably connected skateboards; a folding assembly which is telescopically arranged and connected to the skateboard assembly for controlling the angle between adjacent skateboards in the skateboard assembly; an extending and retracting assembly which is telescopically arranged on the main body 1 of the engineering vehicle and connected to the skateboard assembly for driving the skateboard assembly to extend to the hydroplaning state or retract to fit the surface of the main body 1 of the engineering vehicle.

[0068] It should be noted that the folding assembly can be any telescopic structural component such as an electric cylinder, a pneumatic cylinder, or an oil cylinder, and the extending and retracting assembly can be any telescopic structural component such as an electric cylinder, a pneumatic cylinder, or an oil cylinder, which is specifically determined according to the actual situation.

[0069] During the use process, the angle between adjacent skateboards can be controlled through the folding assembly so that the skateboard assembly contracts to different angles; the extending and retracting assembly drives the entire skateboard assembly to extend to the hydroplaning state or retract to a position where it fits the surface of the main body 1 of the engineering vehicle, simplifying the control process of the contraction and folding of the skateboard assembly and facilitating the operation.

[0070] Preferably, two sets of hydroplane boards can be provided, so that the skateboard assembly includes an upper hydroplane board 22 and a lower hydroplane board 21 which are hinged, and the other end of the lower hydroplane board 21 is hinged to the main body 1 of the engineering vehicle.

[0071] As Figure 1 shown, the folding assembly includes a connecting rod 23, a first folding oil cylinder 24, and a second folding oil cylinder 25. One end of the connecting rod 23 is hinged to the hinge connection between the upper hydroplane board 22 and the lower hydroplane board 21, and the other end is hinged to both the first folding oil cylinder 24 and the second folding oil cylinder 25, and the connecting rod 23, the first folding oil cylinder 24, and the second folding oil cylinder 25 are hinged at the same position. The other end of the first folding oil cylinder 24 is hinged to the first oil cylinder hinge seat 221 of the upper hydroplane board 22, and the other end of the second folding oil cylinder 25 is hinged to the second oil cylinder hinge seat 211 of the lower hydroplane board 21; the extending and retracting assembly includes a skateboard extending and retracting oil cylinder 26 with one end hinged to the skateboard assembly and the other end hinged to the main body 1 of the engineering vehicle.

[0072] During use, the angle between the upper water slide plate 22 and the lower water slide plate 21 can be adjusted by controlling the extension and retraction of the first folding oil cylinder 24 and the second folding oil cylinder 25. By adjusting the extension and retraction of the slide plate deployment and retraction oil cylinder 26, the upper water slide plate 22 and the lower water slide plate 21 can be rotated around the hinge axis at the hinge where the lower water slide plate 21 is hinged to the main body 1 of the engineering vehicle, so that the water slide device 2 can be retracted and folded to fit the surface of the main body 1 of the engineering vehicle or extended to the water slide state.

[0073] Preferably, the through groove can be set as a through hole 212, and the through hole 212 is arranged on the lower water slide plate 21.

[0074] As Figures 1-5 shown, the earthmoving device 3 includes: an earthmoving shovel assembly for earthmoving operations; an earthmoving arm 31, one end of which is rotatably connected to the main body 1 of the engineering vehicle, and the other end is connected to the earthmoving shovel assembly; an angle adjustment assembly for adjusting the angle between the earthmoving shovel and the earthmoving arm 31 of the assembly; a telescopic assembly connected to the main body 1 of the engineering vehicle for driving the earthmoving arm 31 to rotate relative to the main body 1 of the engineering vehicle.

[0075] The angle adjustment assembly can be any telescopic structural assembly such as an electric cylinder, a cylinder, an oil cylinder, etc., and the telescopic assembly can be any telescopic structural assembly such as an electric cylinder, a cylinder, an oil cylinder, etc., which is specifically determined according to the actual situation.

[0076] During use, the earthmoving shovel assembly is connected to the main body 1 of the engineering vehicle through the earthmoving arm 31. The angle between the earthmoving shovel and the earthmoving arm 31 of the assembly is adjusted by the angle adjustment assembly so that the earthmoving shovel assembly can adapt to earthmoving operations on different road surfaces or in different road conditions; the telescopic assembly drives the earthmoving arm 31 to rotate relative to the main body 1 of the engineering vehicle so that the earthmoving shovel assembly can be moved to a suitable earthmoving position or a suitable storage position, which is specifically determined according to the actual situation.

[0077] The angle adjustment assembly can include at least one set of variable shovel oil cylinders 37. One end of the variable shovel oil cylinder 37 is hinged to the earthmoving arm 31, and the other end is hinged to the earthmoving shovel assembly; the telescopic assembly includes a telescopic oil cylinder 38 with one end hinged to the main body 1 of the engineering vehicle and the other end hinged to the earthmoving arm 31; as Figure 9 shown, two sets of variable shovel oil cylinders 37 are provided, and both sets of variable shovel oil cylinders 37 have one end hinged to the earthmoving arm 31 and the other end hinged to the earthmoving shovel assembly. During use, preferably, when the variable shovel oil cylinder 37 is in the fully extended state, the earthmoving shovel assembly and the earthmoving arm 31 are in the same straight line. When the variable shovel oil cylinder 37 is in the retracted state, the angle between the earthmoving shovel assembly and the earthmoving arm 31 becomes smaller; the specific angle adjustment range needs to be determined according to the actual situation.

[0078] As Figure 1, the downslide plate 21 and the earthmoving arm 31 are hinged to the same position of the construction vehicle body 1, and this position is the hinge position 11.

[0079] In another specific embodiment, the earthmoving blade assembly includes an earthmoving blade main body 32 and a wing blade assembly, and at least one of the two ends in the length direction of the earthmoving blade main body 32 is hingedly connected with a wing blade assembly.

[0080] Furthermore, the wing blade assembly can include a left wing blade 34, a left wing blade adjusting oil cylinder 35 for driving the left wing blade 34 to rotate relative to the earthmoving blade main body 32, a right wing blade 33, and a right wing blade adjusting oil cylinder 36 for driving the right wing blade 33 to rotate relative to the earthmoving blade main body 32; the left wing blade 34 is hingedly connected to one end in the length direction of the earthmoving blade main body 32, and the right wing blade 33 is hingedly connected to the other end in the length direction of the earthmoving blade main body 32.

[0081] In order to further reduce the mass of the amphibious operation construction vehicle, the earthmoving blade main body 32, the left wing blade 34, the right wing blade 33, and the earthmoving arm 31 can all be set as hollow structures.

[0082] As Figures 7-9 shown, it is a schematic diagram of the earthmoving blade assembly in the straight blade state. In this state, both the left wing blade adjusting oil cylinder 35 and the right wing blade adjusting oil cylinder 36 extend, so that the earthmoving blade main body 32, the left wing blade 34, and the right wing blade 33 are in the same plane, and the length of the earthmoving blade assembly is adjusted to the longest state, which can be used in scenarios with larger requirements for the operation width and improve the obstacle clearing speed.

[0083] As Figures 10-12 shown, it is a schematic diagram of the earthmoving blade assembly in the V-blade state. In this state, both the left wing blade adjusting oil cylinder 35 and the right wing blade adjusting oil cylinder 36 extend a part of their lengths, so that the earthmoving blade main body 32, the left wing blade 34, and the right wing blade 33 form a similar V-shaped structure, and there are certain angles between the earthmoving blade main body 32 and the left wing blade 34, and the right wing blade 33, which can make the cleared obstacles move backward along the left wing blade 34 and the right wing blade 33, and are suitable for occasions with special requirements.

[0084] As Figures 13-15 shown, it is a schematic diagram of the earthmoving blade assembly in the single-side blade state. In this state, one of the left wing blade adjusting oil cylinder 35 and the right wing blade adjusting oil cylinder 36 extends a part of its length, and the other extends completely, so that one of the left wing blade 34 and the right wing blade 33 is flush with the earthmoving blade main body 32, and the other has a certain angle with the earthmoving blade main body 32. During the use process, the length of the earthmoving blade assembly is increased to a certain extent, and at the same time, the cleared obstacles can move backward along one of the left wing blade 34 and the right wing blade 33, and are suitable for occasions with special requirements.

[0085] As Figures 16-18As shown, it is a schematic diagram of the bulldozing blade assembly in the folded state. In this state, the left-wing blade adjusting cylinder 35 and the right-wing blade adjusting cylinder 36 both retract, causing the left-wing blade 34 and the right-wing blade 33 to rotate to positions where they are in contact with the side surface of the bulldozing arm 31. Figures 16-18 When the left-wing blade 34 and the right-wing blade 33 rotate to positions where they are in contact with the side surface of the bulldozing arm 31, the rotation angle relative to the straight-blade state is 90°. Of course, depending on the actual situation, it can also be other rotation angles, which are specifically determined according to the actual situation. In this state, the length of the bulldozing blade assembly reaches the minimum, and it can be applicable to occasions with a relatively narrow width or other occasions with special requirements.

[0086] Preferably, the through hole 212 in the lower water slide plate 21 cooperates with Figures 16-18 the bulldozing blade assembly in the state shown. That is, during the process of the bulldozing device 3 contracting and folding, it is necessary to retract both the left-wing blade adjusting cylinder 35 and the right-wing blade adjusting cylinder 36, causing the left-wing blade 34 and the right-wing blade 33 to rotate to positions where they are in contact with the side surface of the bulldozing blade main body 32, and then control the retraction of the telescopic cylinder 38 so that the bulldozing device 3 passes through the through hole 212 and enters the cavity.

[0087] In another specific embodiment, as Figure 3 shown, it is a schematic structural diagram of the amphibious operation engineering vehicle in the transportation state. In this state, the crawlers extend out of the vehicle body, the ground clearance of the whole vehicle is about 400 millimeters, the upper water slide plate 22 and the lower water slide plate 21 are folded, the first folding cylinder 24 and the second folding cylinder 25 are fully retracted, causing the upper water slide plate 22 and the lower water slide plate 21 to fold at an angle, and then the slide plate expansion and retraction cylinder 26 is fully retracted, causing the lower water slide plate 21 to fit the lower inclined surface of the vehicle body and the upper water slide plate 22 to fit the upper inclined surface of the vehicle body. The left-wing blade adjusting cylinder 35 and the right-wing blade adjusting cylinder 36 are fully retracted, and the variable blade cylinder 37 is fully extended, causing the right-wing blade 33 and the left-wing blade 34 to closely fit the bulldozing arm 31; the water-facing surfaces of the right-wing blade 33, the left-wing blade 34, the bulldozing arm 31, and the bulldozing blade main body 32 are in the same plane, and then the telescopic cylinder 38 is fully retracted, causing the entire bulldozing device 3 to be fully retracted into the front of the vehicle head; in this way, the bulldozing device 3 and the lower water slide plate 21 are in the same plane, without affecting the approach angle of the whole vehicle.

[0088] As Figure 4 、 5As shown in the figure, it is a schematic structural diagram of an amphibious operation engineering vehicle in the water navigation state. In this state, the crawlers are retracted into the main body 1 of the engineering vehicle. The left-wing shovel adjustment cylinder 35 and the right-wing shovel adjustment cylinder 36 are fully retracted, and the variable shovel cylinder 37 is fully extended, which can make the right-wing shovel 33, the left-wing shovel 34 and the bulldozing arm 31 fit closely; the water-facing surfaces of the right-wing shovel 33, the left-wing shovel 34, the bulldozing arm 31 and the main body 32 of the bulldozing shovel are in the same plane, and at the same time, the bulldozing shovel assembly and the bulldozing arm 31 in the folded state are just the same size as the through hole 212 dug by the lower water slide 21. When the first folding cylinder 24 and the second folding cylinder 25 are fully extended to ensure that the upper water slide 22 and the lower water slide 21 are in the same plane, when the opening angle of the slide plate assembly is the same as the opening angle of the bulldozing shovel assembly, the right-wing shovel 33, the left-wing shovel 34, the bulldozing arm 31, the main bulldozing shovel, the upper water slide 22 and the lower water slide 21 are in the same plane. When there is a water jet propeller at the rear of the whole vehicle, it can achieve the water skiing effect.

[0089] As Figure 6 As shown in the figure, it is a schematic structural diagram of an amphibious operation engineering vehicle in the bulldozing working state. In this state, the crawlers extend out of the vehicle body, and the ground clearance of the whole vehicle is about 400 mm. The first folding cylinder 24 and the second folding cylinder 25 are fully retracted, so that the upper water slide 22 and the lower water slide 21 are folded at an angle. Then the slide plate expansion and retraction cylinder 26 is fully retracted, so that the lower water slide 21 fits the lower inclined surface of the vehicle body, and the upper water slide 22 fits the upper inclined surface of the vehicle body. The telescopic cylinder 38 extends, and the extension length is adjusted according to the actual situation. The variable shovel cylinder 37 contracts, and the contraction length is adjusted according to the cutting soil back angle. Then the left-wing shovel adjustment cylinder 35 and the right-wing shovel adjustment cylinder 36 are fully extended to achieve straight shovel operation. The extended parts of the left-wing shovel adjustment cylinder 35 and the right-wing shovel adjustment cylinder 36 achieve V-shovel operation. Only one of the left-wing shovel adjustment cylinder 35 and the right-wing shovel adjustment cylinder 36 extends to achieve single-side shovel operation.
