Technical Field

[0001] The present invention relates to the technical field of engineering vehicles, and in particular to a bulldozer assembly and an amphibious engineering operation vehicle. Background Art

[0002] Amphibious engineering work vehicles are modified equipment based on the basic chassis of amphibious equipment. They are mainly used for clearing obstacles and opening up paths in complex amphibious environments. Generally, they must be equipped with working devices such as bulldozers, excavators, and grippers. They generally include land driving, water navigation, operations and other working conditions. They are important equipment that is indispensable for landing operations and emergency rescue.

[0003] The bulldozers of some amphibious engineering vehicles require increased structural strength to ensure more reliable earthmoving. However, adding additional reinforcements to the bulldozers could compromise the chassis' dynamic performance and rollover resistance, making improvements to the bulldozers difficult.

[0004] Therefore, how to enhance the structural strength of the bulldozer during bulldozing is a technical problem that those skilled in the art currently need to solve. Summary of the Invention

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] The core of the present invention is to provide a bulldozer assembly that can have higher structural strength when bulldozing. Another core of the present invention is to provide an amphibious engineering vehicle including the bulldozer assembly, wherein the bulldozer assembly can have higher structural strength when bulldozing.

[0031] In the specific embodiment of the bulldozer assembly provided by the present invention, please refer to Figures 1 to 3 , including a bulldozer device 1 and a slide device 2. One end of the bulldozer device 1 and one end of the slide device 2 are both hinged to the vehicle body axis. Specifically, the bulldozer device 1 includes a boom assembly and a bulldozer blade 1.1 connected to one end of the boom assembly, and the other end of the boom assembly is hinged to the vehicle body axis.

[0032] An assembly telescopic drive 3 is connected between the bulldozer device 1 and the slide device 2, so that the slide device 2 can swing relative to the bulldozer device 1 through the telescopic movement of the assembly telescopic drive 3. Specifically, when the telescopic drive 3 telescopes, the bulldozer device 1 remains stationary, allowing the slide device 2 to rotate around the vehicle body axis, thereby achieving the swing of the slide device 2 relative to the bulldozer device 1. The length of the assembly telescopic drive 3 can be locked and unlocked. Specifically, the assembly telescopic drive 3 is an oil cylinder. In other embodiments, the assembly telescopic drive 3 can also be an air cylinder, or it can be realized by a screw rod, push rod, bolt, rivet, welding or other structural connection.

[0033] In this embodiment, the bulldozer 1 and the slide assembly 2 are organically connected via a telescopic actuator assembly 3. When the telescopic actuator assembly 3 is locked, the bulldozer 1 and the slide assembly 2 are rigidly connected and move synchronously, effectively forming a single structure. They reinforce each other, eliminating the need for additional reinforcements on the bulldozer 1 and increasing the structural strength of the bulldozer 1 during bulldozing. When the telescopic actuator assembly 3 is unlocked, the slide assembly 2 no longer moves with the bulldozer 1. The two can move and adjust their postures independently without affecting their respective functions, thus increasing the flexibility of the bulldozer 1.

[0034] Furthermore, the slide device 2 includes a first slide 2.5, a second slide 2.1, and a tilting actuator. One end of the first slide 2.5 is hinged to the vehicle body axle, and the other end is hinged to one end of the second slide 2.1. The tilting actuator is connected between the first slide 2.5 and the second slide 2.1 to drive the second slide 2.1 to swing relative to the first slide 2.5 via the tilting actuator.

[0035] The bulldozer 1 is connected to the vehicle body 4 via a swing actuator 1.2. When the telescopic actuator 3 is locked, the swing actuator 1.2 extends or contracts, driving the bulldozer 1 and the first slide 2.5 in synchronous motion about the vehicle body axis, allowing the slide 2 to rise and fall with the bulldozer 1. When the telescopic actuator 3 is unlocked, the swing actuator 1.2 extends or contracts, but the bulldozer 1 and the first slide 2.5 do not move synchronously, and the slide 2 does not rise or fall with the bulldozer 1.

[0036] Furthermore, the flip driver can drive the second slide 2.1 to fold to fit the first slide 2.5, and drive the second slide 2.1 to unfold to form a flat plate structure with the first slide 2.5. Specifically, the first slide 2.5 and the second slide 2.1 can flip relative to each other at an angle of 180 degrees. Specifically, the second slide 2.1 unfolding to form a flat plate structure with the first slide 2.5 can mean that a predetermined plane of the second slide 2.1 and a predetermined plane of the first slide 2.5 are coplanar. Figure 2As shown, under the water navigation condition, the second slide plate 2.1 is unfolded to form a flat plate structure with the first slide plate 2.5, and the bulldozer blade 1.1 can be completely exposed to the water surface. Figure 3 As shown, in the bulldozing operation, the second slide plate 2.1 is folded to fit the first slide plate 2.5, so that the slide plate device 2 is folded and retracted above the bulldozing plane without affecting the bulldozing operation.

[0037] Of course, in other embodiments, the relative turning range of the first slide 2.5 and the second slide 2.1 can also be set to other settings. For example, the relative turning angle of the first slide 2.5 and the second slide 2.1 can be 350 degrees.

[0038] Furthermore, the tilt actuator includes a connecting plate, a first telescopic actuator 2.4, and a second telescopic actuator 2.2. The first telescopic actuator 2.4 is hinged at both ends to the connecting plate and the first slide 2.5, respectively. The second telescopic actuator 2.2 is hinged at both ends to the connecting plate and the second slide 2.1, respectively. The connecting plate is hinged to the first slide 2.5. Specifically, the first telescopic actuator 2.4 and the second telescopic actuator 2.2 are hydraulic cylinders. In other embodiments, the first telescopic actuator 2.4 and the second telescopic actuator 2.2 can also be pneumatic cylinders, or alternatively, they can be connected using a screw rod, push rod, bolt, rivet, welding, or other structural connection.

[0039] Preferably, the connecting plate is a tripod 2.3, and the first telescopic driver 2.4, the second telescopic driver 2.2 and the first slide plate 2.5 are hinged to the three vertex positions of the tripod 2.3 respectively.

[0040] The double oil cylinders of the first telescopic drive 2.4 and the second telescopic drive 2.2 can increase the stroke, and the tripod 2.3 can increase the lever arm and angle, so as to achieve a large-angle amplitude change of the second slide 2.1, forming a large-scale folding slide device 2, which can meet the requirements of unfolding during water navigation without affecting the navigation posture and anti-overturning ability of the original equipment.

[0041] Of course, in other embodiments, the tripod 2.3 can be replaced by a quadrilateral, pentagonal, or more polygonal frame, or the connecting plate can be replaced by a connecting rod rocker mechanism. In addition, the flip driver can also be configured as a rotation drive motor connected between the first slide 2.5 and the second slide 2.1.

[0042] Furthermore, the bulldozer 1 is made of titanium alloy. Of course, the slide plate 2 and other pin structures, such as the vehicle body axle, can also be made of the same material as the bulldozer 1 to further achieve lightweighting. Furthermore, the bulldozer 1 and pins can also be made of other alloys and non-metallic materials.

[0043] The bulldozer assembly provided in this embodiment is used in amphibious engineering vehicles. During water navigation, the bulldozer blade 1.1 is fully exposed above the water surface, without affecting the water performance of the original slide plate. During bulldozing operations, the second slide plate 2.1 folds downward and maintains a certain distance from the bulldozing plane. It can be raised or lowered with or without following the bulldozer 1 without affecting the bulldozer 1's bulldozing operation. The bulldozer 1 and slide plate 2 are combined into an organic whole, retaining their respective functions while increasing their strength and rigidity, achieving lightweight design without affecting the original equipment's navigational attitude and anti-overturning capability. During bulldozing operations, the slide plate does not affect the bulldozer 1's bulldozing operation.

[0044] In addition to the above bulldozer components, such as Figure 1 As shown, the present invention further provides an amphibious engineering vehicle, comprising a bulldozer assembly and a vehicle body 4. The bulldozer assembly may be any of the bulldozer assemblies described in the above embodiments. A vehicle body axle is provided on the vehicle body 4, and a bulldozer device 1 is connected to the vehicle body 4 via a swing actuator 1.2, which drives the bulldozer device 1 to swing about the vehicle body axle.

[0045] The swing actuator 1.2 is a telescopic actuator, specifically a hydraulic cylinder, with its ends hinged to the vehicle body 4 and the bulldozer 1, respectively. Alternatively, the swing actuator 1.2 can be a pneumatic cylinder, or it can be implemented using a screw, push rod, bolt, rivet, weld, or other structural connection. Of course, in other embodiments, the swing actuator 1.2 can also be a rotary drive motor connected between the vehicle body shaft and the bulldozer 1.
