Description

Technical Field

[0001] The present invention relates to the technical field of construction machinery, and particularly relates to an amphibious engineering vehicle. Background Art

[0002] An amphibious engineering vehicle is a vehicle that can travel on land and also navigate in rivers, seas, etc., and is widely used in various industries such as military, mining, and tourism.

[0003] In the prior art, a hydroplane device or a bulldozing device is provided at the front of the vehicle body. The hydroplane device is used to increase lift when the vehicle is navigating in water, and the bulldozing device is used to remove road obstacles when the vehicle is traveling on land, etc. However, the hydroplane device and the bulldozing device at the front of the vehicle usually interfere with each other during the operation process, and cannot complete the multi-functional cooperation, which affects the speed of the vehicle when navigating in water and the speed of the bulldozing work on land, so that the vehicle cannot travel at a high speed during the operation to meet the operation requirements.

[0004] Therefore, how to avoid the influence on the operation speed of the vehicle and the navigation speed in water due to the inability of the hydroplane device and the bulldozing device to complete the cooperation is a technical problem that those skilled in the art need to solve at present.

[0006] To achieve the above purpose, the present invention provides an amphibious engineering vehicle, including a vehicle body. A hydroplane device and a bulldozing device are provided at the head of the vehicle body. The bulldozing device includes a bulldozing arm movably connected to the vehicle body, and a first bulldozing driving component connected to the bulldozing arm and used to drive the bulldozing arm to move relative to the vehicle body to realize unfolding and retracting. The hydroplane device includes a hydroplane component, a hydroplane connecting rod, and a first hydroplane driving component. The two ends of the hydroplane connecting rod are respectively rotatably connected to the hydroplane component and the vehicle body. The two ends of the first hydroplane driving component are respectively rotatably connected to the hydroplane connecting rod and the vehicle body; by driving the hydroplane connecting rod through the first hydroplane driving component, the hydroplane connecting rod drives the hydroplane component away from the vehicle body to create space when the bulldozing device unfolds and retracts.

[0007] Optionally, the bulldozing arm is hinged to the vehicle body.

[0008] Optionally, the two ends of the first bulldozing driving component are respectively hinged to the bulldozing arm and the vehicle body, and the bulldozing arm is driven to extend out of the vehicle body and retract into the vehicle body respectively through the extension and retraction movements of the first bulldozing driving component.

[0009] Optionally, the bulldozer arm is provided with a main bulldozer blade which can be flipped up and down relative to the bulldozer arm.

[0010] Optionally, it further comprises a second bulldozer driving assembly, both ends of which are respectively hinged to the main bulldozer blade and the bulldozer arm, and the second bulldozer driving assembly drives the main bulldozer blade to rotate relative to the bulldozer arm.

[0012] Optionally, the upper water ski and the lower water ski are hinged on a water ski hinge seat, and further include a second water ski driving assembly, wherein two ends of the second water ski driving assembly are respectively hinged to the water ski hinge seat and the vehicle body.

[0013] Optionally, the second water ski drive assembly includes an outrigger, a main arm and a water ski extension and retraction cylinder, the outrigger and the main arm are slidably connected, one end of the water ski extension and retraction cylinder is hinged to the outrigger, and the other end is hinged to the main arm, one end of the outrigger away from the main arm is hinged to the water ski hinge seat, and one end of the main arm away from the outrigger is hinged to the vehicle body.

[0014] Optionally, a third water ski driving assembly is further included, and two ends of the third water ski driving assembly are respectively hinged to the extension arm and the upper water ski.

[0015] Optionally, the vehicle body is also provided with an excavating device for digging debris.

[0016] Compared with the above background art, the amphibious engineering vehicle provided by the embodiment of the present invention includes a vehicle body. A hydroplane device and an earthmoving device are provided at the head of the vehicle body. The earthmoving device includes an earthmoving arm and a first earthmoving driving component. Among them, the earthmoving arm is movably connected to the vehicle body, and the first earthmoving driving component is connected to the earthmoving arm. The first earthmoving driving component is used to drive the earthmoving arm to move relative to the vehicle body to realize the expansion and retraction of the earthmoving device and the adjustment of the cutting depth.

One end of the hydroplane connecting rod is rotatably connected to the hydroplane component, and the other end of the hydroplane connecting rod is rotatably connected to the vehicle body. One end of the first hydroplane driving component is rotatably connected to the hydroplane connecting rod, and the other end of the first hydroplane driving component is rotatably connected to the vehicle body. In this way, under the driving action of the first hydroplane driving component, the hydroplane connecting rod can drive the hydroplane component away from the vehicle body, so as to create space when the earthmoving device expands and retracts, so as to avoid the earthmoving device. Compared with the traditional one that cannot cooperate with the earthmoving device and the hydroplane device to adapt to the switching of different states of the engineering vehicle, for the amphibious engineering vehicle provided by the embodiment of the present invention, when the earthmoving device needs to be extended from the vehicle body or retracted into the vehicle body, first, the first hydroplane driving component is used to drive the hydroplane connecting rod, and the hydroplane connecting rod drives the hydroplane component away from the vehicle body to create space when the earthmoving device expands and retracts. Then, the first earthmoving driving component is used to drive the earthmoving arm to move relative to the vehicle body to realize the expansion and retraction of the earthmoving device. When used for shipborne transportation and water navigation, the earthmoving device is retracted into the vehicle body. When earthmoving operations are carried out, the earthmoving device is extended from the vehicle body. In this way, by operating the hydroplane device and the earthmoving device successively, it is possible to prevent interference between the hydroplane device and the earthmoving device during hydroplane navigation and earthmoving operations. Therefore, through the multi-functional cooperation of the hydroplane device and the earthmoving device, it is possible to adapt to different operating states of the engineering vehicle, which can not only meet the driving speed requirements of the vehicle during shipborne transportation and water navigation, but also ensure the function of earthmoving operations, thereby greatly improving the operating efficiency of the engineering vehicle.

Specific embodiments

[0031] 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.

[0032] The core of the present invention is to provide an amphibious engineering vehicle, which can not only meet the driving speed requirements during shipboard transportation and water navigation, but also ensure the function of earthmoving operation, thereby greatly improving the operation efficiency of the engineering vehicle and the water navigation speed.

[0033] In order to enable those skilled in the art of the present technology to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] It should be noted that the orientation terms such as "upper end, lower end, left side, right side" described below are defined based on the accompanying drawings of the specification.

[0035] Please refer to Figures 1 to 9 , Figure 1 which is a schematic structural diagram of the amphibious engineering vehicle provided by the embodiment of the present invention; Figure 2 is Figure 1 a schematic structural diagram of the earthmoving device after expansion in Figure 3 a schematic diagram of the first perspective of the amphibious engineering vehicle during shipboard transportation; Figure 4 a schematic diagram of the second perspective of the amphibious engineering vehicle during shipboard transportation; Figure 5 a schematic diagram of the first perspective of the amphibious engineering vehicle during high-speed water navigation; Figure 6 a schematic diagram of the second perspective of the amphibious engineering vehicle during high-speed water navigation; Figure 7 a schematic diagram of the amphibious engineering vehicle when the earthmoving operation is in a state where the hydroplane device is partially expanded; Figure 8 a schematic diagram of the earthmoving device of the amphibious engineering vehicle extending out of the vehicle body during earthmoving operation; Figure 9 a schematic diagram of the earthmoving device of the amphibious engineering vehicle in an operating state during earthmoving operation.

[0036] As Figure 1 shown, the amphibious engineering vehicle provided by the embodiment of the present invention includes a vehicle body 1. A hydroplane device 2 and an earthmoving device 3 are provided at the head of the vehicle body 1. In this embodiment, the earthmoving device 3 is arranged below the hydroplane device 2. The hydroplane device 2 is used to lift the lift force when the vehicle body 1 sails in water, so that the vehicle body 1 can rise from the water as soon as possible. The hydroplane device 2 can also increase the water-facing area and reduce the navigation resistance, thereby facilitating the improvement of the navigation speed; the earthmoving device 3 is used to remove road obstacles when the vehicle travels on land, etc.

[0037] Furthermore, the earthmoving device 3 includes an earthmoving arm 31 and a first earthmoving drive assembly 32. Among them, the earthmoving arm 31 is movably connected to the vehicle body 1, and the first earthmoving drive assembly 32 is connected to the earthmoving arm 31. The first earthmoving drive assembly 32 is used to drive the earthmoving arm 31 to move relative to the vehicle body 1 to realize the expansion and retraction of the earthmoving device 3.

[0038] The water skiing board device 2 includes a water skiing board assembly 20, a water skiing board connecting rod 22, and a first water skiing board driving assembly 23. One end of the water skiing board connecting rod 22 is rotatably connected to the water skiing board assembly 20, and the other end of the water skiing board connecting rod 22 is rotatably connected to the vehicle body 1. One end of the first water skiing board driving assembly 23 is rotatably connected to the water skiing board connecting rod 22, and the other end of the first water skiing board driving assembly 23 is rotatably connected to the vehicle body 1. In this way, under the driving action of the first water skiing board driving assembly 23, the water skiing board connecting rod 22 can drive the water skiing board assembly 20 away from the vehicle body 1, so as to create space when the earth moving device 3 is unfolded and retracted, so as to avoid the earth moving device 3.

[0039] Compared with the traditional one that cannot cooperate with the earth moving device 3 and the water skiing board device 2 to adapt to different operating states of the engineering work vehicle, for the amphibious engineering work vehicle provided by the embodiment of the present invention, when the earth moving device 3 needs to be unfolded from the vehicle body 1 or retracted into the vehicle body 1, first, the first water skiing board driving assembly 23 drives the water skiing board connecting rod 22, and the water skiing board connecting rod 22 drives the water skiing board assembly 20 away from the vehicle body 1 to create space when the earth moving device 3 is unfolded and retracted. Then, the first earth moving driving assembly 32 drives the earth moving arm 31 to move relative to the vehicle body 1 to realize the unfolding and retraction of the earth moving device 3.

[0040] It should be noted that when in shipborne transportation and water navigation, the earth moving device 3 needs to be retracted into the vehicle body 1, and when in earth moving operation, the earth moving device 3 needs to be unfolded from the vehicle body 1. The above setting method operates the water skiing board device 2 and the earth moving device 3 successively to prevent interference between the water skiing board device 2 and the earth moving device 3 during water skiing and earth moving operations. Thus, through the multi-functional cooperation of the water skiing board device 2 and the earth moving device 3, it can adapt to different operating states and navigation states of the engineering work vehicle, can not only meet the driving speed requirements of the vehicle during shipborne transportation and water navigation, but also ensure the function of earth moving operation, and thus can greatly improve the operation efficiency of the engineering work vehicle.

[0041] Preferably, the earth moving arm 31 is hinged to the vehicle body 1. Specifically, one end of the earth moving arm 31 is hinged to the vehicle body 1, one end of the first earth moving driving assembly 32 is hinged to the vehicle body 1, and the other end is hinged to the middle of the earth moving arm 31. The first earth moving driving assembly 32 is specifically a first earth moving oil cylinder. Through the extension and contraction movements of the first earth moving driving assembly 32, the earth moving arm 31 is respectively driven to be unfolded from the vehicle body 1 and retracted into the vehicle body 1, and the earth moving cutting depth is appropriately adjusted. When in shipborne transportation and water navigation, the earth moving device 3 needs to be retracted into the vehicle body 1, and when in earth moving operation, the earth moving device 3 needs to be unfolded from the vehicle body 1.

[0042] Of course, according to actual needs, the above-mentioned earth-pushing arm 31 can also be set to be slidably connected to the vehicle body 1. At this time, the earth-pushing arm 31 is coaxially arranged with the first earth-pushing drive assembly 32, and the telescopic movement of the first earth-pushing drive assembly 32 is used to realize the unfolding and retracting of the earth-pushing arm 31. In this article, the setting method of the earth-pushing arm 31 being hinged to the vehicle body 1 is preferably adopted.

[0043] In addition, a main earth-pushing shovel 30 that can be turned up and down relative to the earth-pushing arm 31 is provided on the earth-pushing arm 31. The main earth-pushing shovel 30 is hinged to one end of the earth-pushing arm 31 away from the vehicle body 1. At the same time, a second earth-pushing drive assembly 33 is also provided between the earth-pushing arm 31 and the main earth-pushing shovel 30. The second earth-pushing drive assembly 33 is specifically a telescopic oil cylinder assembly. One end of the second earth-pushing drive assembly 33 is hinged to the earth-pushing arm 31, and the other end is hinged to the main earth-pushing shovel 30. In this way, through the telescopic movement of the second earth-pushing drive assembly 33, the main earth-pushing shovel 30 rotates relative to the earth-pushing arm 31 to adjust the relative angle state between the main earth-pushing shovel 30 and the earth-pushing arm 31. During operation, according to the cutting depth and the cutting angle, the angle between the main earth-pushing shovel 30 and the earth-pushing arm 31 is adjusted. In the transportation state, the angle between the main earth-pushing shovel 30 and the earth-pushing arm 31 is 180 degrees (at this time, the second earth-pushing drive assembly 33 is in a fully extended state), so that the main earth-pushing shovel 30 and the earth-pushing arm 31 can be a plane on the water-facing side.

[0044] It should be noted that the hinge shafts at both ends of the above-mentioned earth-pushing arm 31, the hinge shafts at both ends of the first earth-pushing drive assembly 32, and the hinge shafts at both ends of the second earth-pushing drive assembly 33 are all horizontally arranged, and the first earth-pushing drive assembly 32 is specifically a first earth-pushing oil cylinder assembly, and the second earth-pushing drive assembly 33 is specifically a second earth-pushing oil cylinder assembly.

[0045] Furthermore, as Figure 2 shown, a right wing shovel 301 and a left wing shovel 302 are respectively provided on both sides of the main earth-pushing shovel 30. The right wing shovel 301 is hinged to the main earth-pushing shovel 30, and the left wing shovel 302 is hinged to the main earth-pushing shovel 30, and the hinge shafts of the right wing shovel 301 and the main earth-pushing shovel 30 and the hinge shafts of the left wing shovel 302 and the main earth-pushing shovel 30 are all arranged in the vertical direction.

[0046] In addition, a right wing shovel oil cylinder 303 and a left wing shovel oil cylinder 304 are also included. One end of the right wing shovel oil cylinder 303 is hinged to the right wing shovel 301, and the other end is hinged to the main earth-pushing shovel 30. In this way, through the telescopic movement of the right wing shovel oil cylinder 303, the angle between the right wing shovel 301 and the main earth-pushing shovel 30 can be changed; one end of the left wing shovel oil cylinder 304 is hinged to the left wing shovel 302, and the other end is hinged to the main earth-pushing shovel 30. In this way, through the telescopic movement of the left wing shovel oil cylinder 304, the angle between the left wing shovel 302 and the main earth-pushing shovel 30 can be changed.

[0047] That is to say, by extending and retracting the right-wing shovel oil cylinder 303 and the left-wing shovel oil cylinder 304, functions such as straight shoveling, single-side shoveling, and V-shaped shoveling of the shovel blade can be achieved. It should be noted that the so-called straight shoveling of the shovel blade means that both the right-wing shovel oil cylinder 303 and the left-wing shovel oil cylinder 304 are fully extended. At this time, the angle between the right-wing shovel 301 and the main earth-pushing shovel 30 is 180°, and the angle between the left-wing shovel 302 and the main earth-pushing shovel 30 is 180°; the so-called single-side shoveling means that either the right-wing shovel oil cylinder 303 or the left-wing shovel oil cylinder 304 is fully extended, and the other is not fully retracted. At this time, the angle between the right-wing shovel 301 (or the left-wing shovel 302) and the main earth-pushing shovel 30 is 180°, and the angle between the left-wing shovel 302 (or the right-wing shovel 301) and the main earth-pushing shovel 30 is a certain angle; the so-called V-shaped shoveling means that the angle between the right-wing shovel 301 and the main earth-pushing shovel 30 is a preset angle between 90° and 180°, and the angle between the left-wing shovel 302 and the main earth-pushing shovel 30 is a preset angle between 90° and 180°.

[0048] Meanwhile, when both the right-wing shovel oil cylinder 303 and the left-wing shovel oil cylinder 304 are in the fully retracted state, the right-wing shovel 301 can be closely attached to the earth-pushing arm 31, and the left-wing shovel 302 can be closely attached to the earth-pushing arm 31, ensuring that the wing shovels do not exceed the width during transportation and in the water state, thereby achieving the effect of reducing water resistance.

[0049] To optimize the structure of the hydroplane assembly 20, the above-mentioned hydroplane assembly 20 includes an upper hydroplane 201 and a lower hydroplane 202. The upper hydroplane 201 is hinged to the lower hydroplane 202, and the lower hydroplane 202 is hinged to the hydroplane link 22. Specifically, the upper hydroplane 201 is hinged to the lower hydroplane 202 on the hydroplane hinge seat 21. Meanwhile, it also includes a second hydroplane drive assembly 24. One end of the second hydroplane drive assembly 24 is hinged to the hydroplane hinge seat 21, and the other end is hinged to the vehicle body 1.

[0050] That is to say, one end of the hydroplane link 22 is hinged to the lower hydroplane 202, and the other end is hinged to the vehicle body 1. Meanwhile, one end of the first hydroplane drive assembly 23 is hinged to a certain position in the middle section of the hydroplane link 22, and the other end is hinged to the vehicle body 1. In this way, by extending and retracting the first hydroplane drive assembly 23, the distance between the lower end of the lower hydroplane 202 and the front of the vehicle can be adjusted. When the first hydroplane drive assembly 23 is fully retracted, the lower end of the lower hydroplane 202 is equivalent to a fixed hinge point. During hydroplaning, the lower hydroplane 202 plays the role of the main load-bearing point.

[0051] More specifically, the second water ski board drive assembly 24 includes an extension arm 241, a main arm 242, and a water ski board deployment and retraction oil cylinder 243. The water ski board deployment and retraction oil cylinder 243 is disposed within the main arm 242. The extension arm 241 and the main arm 242 are slidably connected. One end of the water ski board deployment and retraction oil cylinder 243 is hinged to the extension arm 241, and the other end is hinged to the main arm 242. The end of the extension arm 241 remote from the main arm 242 is hinged to the water ski board hinge seat 21, and the end of the main arm 242 remote from the extension arm 241 is hinged to the vehicle body 1. In this way, through the telescopic movement of the water ski board deployment and retraction oil cylinder 243, partial deployment and retraction of the water ski board device 2 can be achieved.

[0052] It should be noted that the lower water ski board 202, the second water ski board drive assembly 24, the water ski board connecting rod 22, and the vehicle body 1 together form a quadrilateral mechanism, which is beneficial to the deployment and retraction effect of the water ski board assembly 20.

[0053] On the above basis, a third water ski board drive assembly 25 is further included. One end of the third water ski board drive assembly 25 is hinged to the extension arm 241, and the other end is hinged to the upper water ski board 201. The third water ski board drive assembly 25 is specifically an upper water ski board deployment and retraction oil cylinder for enabling the upper water ski board 201 to be deployed and retracted. By the telescopic movement of the third water ski board drive assembly 25 and the telescopic movement of the water ski board deployment and retraction oil cylinder 243, the angle between the upper water ski board 201 and the lower water ski board 202 can be changed. When both the third water ski board drive assembly 25 and the water ski board deployment and retraction oil cylinder 243 are fully extended, the upper water ski board 201 and the lower water ski board 202 are flattened, that is, the angle between them is 180°, and the water-facing surfaces of the upper water ski board 201 and the lower water ski board 202 form a plane.

[0054] To facilitate the excavation function, an excavation device is also provided on the vehicle body 1. The excavation device is used to excavate soil when the vehicle body 1 is not moving. Of course, other working attachments can also be provided on the vehicle body 1 to achieve excavation operations in shallow water. The excavation device and the attachments can be arranged on the head of the vehicle body 1 with reference to the arrangement method of the bulldozing device 3.

[0055] The operation state of the amphibious engineering operation vehicle will be specifically described below with reference to the accompanying drawings.

[0056] When in shipborne transportation, the third water ski board drive assembly 25 is fully retracted, the water ski board deployment and retraction oil cylinder 243 is fully retracted, the first water ski board drive assembly 23 is fully retracted, the water ski board assembly 20 is folded on the front surface of the vehicle head, and the corresponding approach angle is ensured. The upper water ski board 201 fits on the inclined surface of the vehicle head. In addition, the bulldozing device 3 is folded and retracted into the vehicle head. At this time, the right wing shovel oil cylinder 303 and the left wing shovel oil cylinder 304 are fully retracted, so that the left and right wing shovels are in a fully folded state. The second bulldozing oil cylinder assembly is fully extended, so that the bulldozing arm 31 and the main bulldozing shovel 30 are in a plane on the water-facing surface. The first bulldozing oil cylinder assembly is fully retracted, so that the entire bulldozing device 3 is hidden in the vehicle head, as shown in Figure 3 and 4 shown.

[0057] When navigating at high speed on water, the water ski assembly 20 is deployed by the hydraulic cylinder and is ensured to have a certain angle with the horizontal plane (generally 8-10°). At this time, the third water ski drive assembly 25 is fully extended, and the water ski deployment and retraction hydraulic cylinder 243 is fully extended, so that the upper water ski 201 and the lower water ski 202 form a plane. The first water ski drive assembly 23 is fully retracted, so that the lower hinge point of the lower water ski 202 fits against the front of the vehicle head. In addition, the bulldozing device 3 is folded and retracted into the vehicle head. At this time, the right wing shovel hydraulic cylinder 303 and the left wing shovel hydraulic cylinder 304 are fully retracted, so that the left and right wing shovels are in a fully folded state. The second bulldozing hydraulic cylinder assembly is fully extended, so that the bulldozing arm 31 and the main bulldozing shovel 30 are in a plane on the water-facing side, which is beneficial to reducing the navigation resistance and increasing the navigation speed. The first bulldozing hydraulic cylinder assembly is fully retracted, so that the entire bulldozing device 3 is hidden in the vehicle head, as Figure 5 and 6 shown.

[0058] When performing bulldozing operations, first open the water ski device 2, then deploy the bulldozing device 3, and then fold the water ski device 2. The specific process is as follows:

[0059] The first water ski drive assembly 23 is fully extended, and the water ski deployment and retraction hydraulic cylinder 243 is fully extended, so that the lower water ski 202 moves away from the vehicle head to create space for the deployment of the bulldozing device 3, as Figure 7 shown;

[0060] The first bulldozing hydraulic cylinder assembly is fully extended, so that the entire bulldozing device 3 is deployed from the vehicle head, that is, the main bulldozing shovel 30, the left wing shovel 302, and the right wing shovel 301 are extended out of the vehicle head, as Figure 8 shown;

[0061] By the telescoping of the two wing shovel hydraulic cylinders, functions such as straight shoveling, single-side shoveling, and V-shaped shoveling of the shovel blade are realized. Specifically, the second bulldozing hydraulic cylinder assembly is fully retracted, so that the main bulldozing shovel 30 maintains a horizontal state and a certain cutting angle. When straight shoveling is required, the two wing shovel hydraulic cylinders are fully extended. When V-shaped shoveling is required, the two wing shovel hydraulic cylinders are half-extended. When single-side shoveling is required, one of the two wing shovel hydraulic cylinders extends and the other does not extend, as Figure 9 shown.

[0062] It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0063] The above has introduced the amphibious engineering operation vehicle provided by the present invention in detail. Specific examples are used in this article to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the solution of the present invention and its core idea. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
