Description

Technical Field

[0001] The present application relates to the field of engineering construction, and in particular to a multifunctional rapid construction equipment vehicle. Background Art

[0002] In the construction field, there are various multifunctional engineering vehicles, such as: a new type of engineering vehicle (CN202021252014.X), which belongs to the field of engineering machinery technology, including a body, a wheel mechanism, a support mechanism and an excavation mechanism; the body is square, and four wheel mechanisms are provided at the four corners of the lower end of the body, support mechanisms are provided on the front and rear sides of the body, and an excavation mechanism is provided on the upper end of the body; the wheel mechanism is hinged to the body, which can raise or lower the height of the body, or raise or lower the height of the wheel mechanism alone, that is, the excavation mechanism can adjust the height of the excavation mechanism, and the support mechanism serves as a support when raising or lowering the height of the wheel mechanism alone. The vehicle wheels can be adjusted in height, and when encountering obstacles, the wheels can be strided. The four support mechanisms also increase the stability of climbing, and the excavation mechanism can operate at an ultra-low level, which is suitable for cleaning garbage pollutants under low bridges.

[0003] For example: a crawler trolley (CN201720070943.0), particularly relating to the field of cranes, aims to be adaptable to a variety of road conditions and places, with high power, low fuel consumption and strong loading capacity, and the whole machine is flexible and stable. It includes a trolley body, a boom, a boom support column, a lifting device and a universal wheel. The boom is connected to the lifting device, and a retractable telescopic boom is provided in the boom. The lifting device is fixedly connected to the boom support column, and the boom support column is fixed at the center of the trolley body; the trolley body is provided with a power system device, which is connected to the universal wheel to drive the universal wheel to rotate, and the universal wheel drives the crawler to rotate and drives the chassis to move; the front and rear ends of the trolley body are provided with folding platforms, and hydraulic support legs are provided on the left and right sides of the folding platform respectively, and the transmission of the whole machine is stable.

[0004] Specifically, existing construction vehicles are not suitable for excavation and lifting operations in specialized scenarios like tunnels. Even when operating in tunnels, separate support structures are required to ensure site safety. Traditional formwork technology has long relied on wooden supports or steel pipe scaffolding systems, resulting in cumbersome construction processes, high resource consumption, and high safety risks. Although modern engineering has introduced improved technologies such as hydraulically adjustable supports and modular steel formwork, existing solutions still have significant limitations in terms of adaptability to complex terrain, rapid assembly efficiency, and versatility in multiple scenarios.

[0005] Especially in special scenarios such as tunnels and wartime emergency fortifications, traditional formwork systems are difficult to meet the needs of efficient construction due to problems such as long disassembly and assembly cycles, poor support accuracy, and weak terrain matching capabilities.

A plurality of telescopic support wheel assemblies 2 are provided on the outer arc surface of the support frame 3, and each telescopic support wheel assemblies 2 is arranged in a divergent structure relative to the support frame 3. One end of each telescopic support wheel assemblies 2 is rigidly connected to the support frame 3, and the other end contacts the arch structure 7 in the tunnel, thereby providing support for the arch structure 7.

[0042] Wheels 6 and tracks 10 are provided on the bottom side of the body 5. The tracks 10 are sleeved on the outside of the wheels 6 to provide the equipment vehicle with a walking function.

[0043] Preferably, the telescopic support wheel group 2 includes: a roller 201, a roller 201 base, a telescopic rod 203 and a mold base 204; the mold base 204 is fixed on the support frame 3; the telescopic rod 203 is fixed on the mold base 204 and is driven by a hydraulic cylinder arranged in the bracket; the roller 201 base is arranged at the end of the telescopic rod 203, and the roller 201 is arranged on the roller 201 base.

[0044] Furthermore, the telescopic support wheel set 2 is in contact with the arch structure 7 via the roller 201, and the roller 201 can roll relative to the arch structure 7. Furthermore, the rolling direction of the roller 201 is parallel to the axial direction of the arch structure 7.

[0045] When the multifunctional rapid construction equipment vehicle is performing excavation operations in the tunnel, the equipment vehicle controls the telescopic support wheel groups 2 on the support frame 3 to perform telescopic movements based on the shape of the arch structure 7 in the tunnel and the distance information from the equipment vehicle to complete the support of the arch structure 7, thereby ensuring the safety of the construction site and avoiding the need to temporarily build a formwork structure.

[0046] Furthermore, when the arch structure 7 of the excavation working surface is completed, the equipment vehicle moves toward the excavation working surface and completes the support of the newly constructed arch structure 7.

[0049] How it works

[0050] 1. Soil excavation and movement

[0051] (1) Open Excavation: The excavation mechanism at the front of the vehicle is used to excavate the ground or ditches. It can be used to excavate tunnels and ditches. The movement of the vehicle and the excavation work can form a continuous working channel. The wheels of the vehicle are equipped with tracks, which can be used in various complex terrains.

[0052] (2) Underground excavation: When the equipment vehicle is conducting underground excavation, the support frame is extended forward and backward so that the assembly vehicle including the excavation structure and the vehicle-mounted platform crane is completely covered within the frame. After the excavation mechanism has excavated a short distance, the arch structure 7 is supported at the front end of the excavation working surface by the telescopic roller group. As the equipment vehicle continues to excavate forward, the telescopic roller group forms a continuous enclosure structure through continuous movement to support the newly formed tunnel surface, thereby realizing the integrated operation of excavation and tunnel construction while protecting the operation of the excavation mechanism.

[0053] 2. Dynamic fitting of structural surfaces

[0054] The support frame controls the telescopic roller assembly's telescopic rods, allowing the rollers to dynamically adjust their position based on the geometry of the arch, achieving conformity to irregular arches. The telescopic rollers are evenly spaced around the support frame's outer surface, ensuring the vehicle's stability on complex terrain.

[0055] 3. Integrated formwork and hoisting operations

[0056] The platform crane can be used to hoist modular structural units, which are connected by plug-in connection (grooves and bumps). The support frame in the middle of the equipment vehicle provides power support for the telescopic roller assembly and the platform crane, realizing the integrated operation of formwork support and hoisting.

[0057] 4. Streamlined frame module

[0058] The vehicle's wheels are equipped with left and right deflection capabilities, allowing for linear twisting. The assembly modules are pre-assembled through BIM simulation, requiring only block size adjustments. When a tunnel curve requires formwork, the vehicle can follow the curve's curvature, completing the curve construction in multiple steps by replacing curves with turns.

[0059] 5. Transportation function

[0060] The equipment vehicle's support frame protects the vehicle when deployed, and its ample interior accommodates a large amount of rescue supplies. Its tracked travel mechanism adapts to the diverse and complex terrain encountered during wartime. If obstacles or gullies obstruct the route, the excavation mechanism and onboard crane work together to ensure smooth transport. During transport, the retractable roller assembly also provides impact cushioning, offering secondary protection against unexpected external impacts such as landslides and stray bullet fragments.

[0061] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
