Abstract
Description
Technical Field
[0001] This utility model belongs to the field of engineering machinery and relates to a multi-functional engineering vehicle. Background Technology
[0002] In the field of tunnel engineering construction, with the continuous advancement of infrastructure construction, tunnels, as key nodes connecting transportation networks, directly affect the progress and cost of the entire project due to their construction quality and efficiency. However, the tunnel construction environment, due to its unique spatial characteristics—narrow and complex—places extremely high demands on construction equipment. Especially in confined tunnels, the integration, adaptability, multifunctionality, and flexibility of equipment become key factors restricting construction efficiency.
[0003] Traditional tunnel construction equipment often reveals numerous shortcomings when facing confined spaces. On one hand, the limited space at the tunnel working face makes equipment installation and layout extremely difficult. Existing large-scale construction equipment is typically bulky and difficult to move and install flexibly within narrow tunnels, increasing construction difficulty and extending the construction period. On the other hand, the series of operations involved in tunnel construction, such as shoveling, loading, and transporting materials, are complex and crucial, requiring equipment with multiple functions to adapt to different construction needs. However, existing equipment on the market often has limited functionality and cannot meet the multi-functional requirements of tunnel construction. In confined tunnels, shoveling is the primary step in the construction process. Due to space constraints, traditional shoveling equipment is difficult to deploy effectively, resulting in low operating efficiency and potential damage to the tunnel walls. The loading process also faces challenges; existing loading equipment often cannot adapt to the material loading requirements within confined spaces, leading to low loading efficiency and impacting construction progress. The transport stage involves moving the shoveled and loaded materials to the designated location, requiring equipment with good maneuverability and stability to ensure the safety of the materials during transportation. However, existing material handling equipment has limited mobility in narrow tunnels and is susceptible to the influence of complex terrain within the tunnels, resulting in low transportation efficiency.
[0004] To address these issues, specialized equipment designed for tunnel construction environments has emerged on the market. However, these devices still have many shortcomings in terms of integration, adaptability, multifunctionality, and flexibility. For example, while some devices are small and can adapt to confined spaces, their functions are limited and cannot meet the diverse needs of tunnel construction. Other devices, although multifunctional, are bulky, complex to operate, and difficult to use flexibly in narrow tunnels.
[0005] In summary, the current market lacks suitable equipment capable of effectively addressing a range of challenges in tunnel environments, particularly in confined tunnels, including equipment installation, material handling, loading, and transportation. Therefore, there is an urgent need to develop a highly integrated, adaptable, multifunctional, and flexible piece of equipment to meet the specific requirements of tunnel construction. Utility Model Content
[0006] In view of this, the purpose of this utility model is to provide a multi-functional engineering vehicle that can independently complete a series of operations such as shoveling, loading and transporting materials, so as to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A multi-functional engineering vehicle includes a traveling mechanism, a hopper, a bucket, a boom, a boom tilting mechanism, and a boom telescopic mechanism. The hopper is detachably placed on the traveling mechanism. There are two booms, which are symmetrically arranged on both sides of the hopper. One end of the boom is hinged to the traveling mechanism, and the other end is hinged to the bucket, which is located in front of the hopper.
[0009] One end of the boom pitch mechanism is hinged to the traveling mechanism, and the other end is hinged to the boom to control the pitch angle of the boom.
[0010] The boom includes an inner boom sleeve and an outer boom sleeve that is slidably fitted on the inner boom sleeve. The end of the outer boom sleeve away from the inner boom sleeve is hinged to the traveling mechanism, and the end of the inner boom sleeve away from the outer boom sleeve is hinged to the bucket. An boom telescopic mechanism is provided on the outer boom sleeve, and the output end of the boom telescopic mechanism is connected to the inner boom sleeve to drive the inner boom sleeve to move axially within the outer boom sleeve, thereby controlling the length of the boom.
[0011] Furthermore, it also includes a bucket angle adjustment mechanism, which is a side-swing cylinder. The side-swing cylinder is fixedly installed on the inner sleeve of the boom, and the output end of the side-swing cylinder is hinged to the bucket. The bucket's tilting angle is controlled by the extension and retraction of the side-swing cylinder in conjunction with the hinge between the bucket and the inner sleeve of the boom, thereby realizing the scooping and unloading of materials by the bucket.
[0012] Furthermore, the side-swing cylinder is hinged to the upper part of the bucket on the side near the traveling mechanism, and the boom inner sleeve is hinged to the lower part of the bucket on the side near the traveling mechanism.
[0013] Furthermore, the bucket is equipped with removable railings.
[0014] Furthermore, the boom pitching mechanism is a pitching cylinder, and the boom telescopic mechanism is a telescopic cylinder.
[0015] Furthermore, the hopper is equipped with lifting rings to facilitate the hoisting of the hopper.
[0016] Furthermore, the walking mechanism includes tracks, track beams, chassis corner supports, and a chassis. The track beams connect the tracks arranged on both sides and are connected to the chassis via the chassis corner supports.
[0017] Furthermore, the hopper is placed on the chassis, and one end of the boom tilting mechanism is hinged to the chassis.
[0018] Furthermore, a tail support rod is hinged to the track crossbeam, and the tail support rod is hinged to the chassis via a tail cylinder, so that the tail support rod can be rotated by the tail cylinder, so that the end of the tail support rod away from the track crossbeam is supported on the ground.
[0019] The beneficial effects of this utility model are as follows:
[0020] This invention integrates shoveling, loading, and transporting functions into a single engineering vehicle through innovative structural design, solving the challenge of multi-equipment collaborative operation in narrow tunnels. Employing a symmetrically arranged double-boom structure, combined with boom pitching and telescopic mechanisms, it achieves dynamic adjustment of boom length and angle, significantly improving adaptability to confined spaces. Simultaneously, the design of a detachable bucket and bucket angle adjustment mechanism allows the equipment to quickly switch functional modules according to working conditions, completing the entire process within limited space. This highly integrated design not only reduces the number of devices and floor space but also optimizes functional expandability through modular combination, representing a groundbreaking innovation in the field of narrow tunnel construction.
[0021] This invention achieves a balance between mobility and stability by introducing a telescopic boom structure and a tail support rod. The sliding fit between the inner and outer sleeves of the boom, combined with the pitch cylinder, allows for precise control of the bucket's working range and material dumping angle. The tail support rod, driven by a cylinder, provides stable support to the ground, preventing chassis swaying during operation. Furthermore, the design of the side-swing cylinder hinged to the upper part of the bucket, combined with the lower hinge point, creates a lever effect, significantly enhancing the scooping torque and reducing energy consumption, making it particularly suitable for the rapid response requirements of complex terrain in tunnels.
[0022] This invention significantly reduces equipment purchase and maintenance costs through functional integration, with a single unit replacing the traditional combination of a forklift, loader, and transport vehicle. The hopper lifting ring design, combined with a tracked chassis, supports rapid lifting and transfer as well as autonomous movement, reducing equipment changeover time. Practical engineering applications show that this equipment can reduce the overall cost of tunnel construction, shorten the construction period, and has significant economic benefits and industry promotion value.

[0036] Furthermore, the bucket angle adjustment mechanism is a side-swing cylinder 2, which is fixedly installed on the inner sleeve of the boom, and the output end of the side-swing cylinder 2 is hinged to the bucket 4.
