Description

Technical Field

[0001] This utility model relates to the field of excavator equipment technology, and in particular to a hydraulic steel pipe folding transfer frame for excavators. Background Technology

[0002] Excavators rely on multiple hydraulic steel pipe systems to transmit oil pressure signals during operation. These hydraulic steel pipes are characterized by their slender structure, curved shape, and irregular size, making them difficult to manufacture and requiring strict transportation and storage conditions. If the hydraulic steel pipes are not properly placed or protected during production, storage, and assembly, they are highly susceptible to quality problems such as impacts, scratches, bending, and deformation, which can affect assembly accuracy and service life.

[0003] To reduce the risk of damage during handling and storage, the industry commonly uses customized workstation equipment or dedicated transfer racks for the classified storage and orderly transfer of hydraulic steel pipes. However, existing transfer racks are generally fixed or rigid frame structures, unable to be shrunk or folded according to usage requirements, leading to problems during the recycling and transportation of the steel pipes after unloading:

[0004] The frame itself occupies a large space, which is not suitable for the actual transport load;

[0005] Low utilization rate of transport vehicles and high recycling costs;

[0006] The equipment has poor versatility and lacks flexibility and modularity.

[0007] In addition, some existing technologies attempt to introduce detachable parts, but most of them are simple parts insertion or fixed plate disassembly, which still makes it difficult to achieve a balance between structural strength, ease of operation and folding efficiency, and is difficult to meet the current industrial demand for multi-category, multi-size and high-efficiency assembly of steel pipes for excavators.

[0008] Therefore, there is an urgent need to provide a special transfer device that is structurally reasonable, has reliable strength, can be easily folded, and can adapt to the dual needs of hydraulic steel pipe storage and transportation, so as to reduce recycling and transportation costs, improve space utilization efficiency, and thus ensure the product quality and process continuity of hydraulic steel pipes. Utility Model Content

[0009] The technical problem this utility model aims to solve is: addressing the issues of excavator hydraulic steel pipes being slender, curved, and irregular in shape, making them susceptible to damage during manufacturing, storage, and transportation, as well as the problems of existing transfer frames being bulky, non-foldable, and wasting significant space during recycling and transportation. This invention provides an excavator hydraulic steel pipe transfer frame with a reasonable structure, reliable support, and convenient folding and storage, thereby achieving orderly support and protective storage of the hydraulic steel pipes, significantly reducing their volume during unloaded recycling, improving transportation efficiency, and lowering usage costs.

[0060] In this embodiment, the main components are connected by bolts or pins, which facilitates loading, unloading, maintenance and replacement, and improves the modular assembly efficiency and maintenance convenience of the device.

[0061] The following description will further illustrate the characteristics and functions of this utility model.

[0062] The transfer frame in this embodiment is composed of multiple components, including a base welded component, a left side frame welded component, a right side frame welded component, a left center support assembly, a right center support assembly, diagonal braces, a central crossbeam, a crossbeam welded component, steel pipes, hinge connecting plates, and left and right bending limiting plates. These components are assembled using standard connectors such as guide keys, hinge pins, pins, or bolts to form a modular structure that can be unfolded and folded. The base welded component serves as the basic support platform for this device, located at the bottom of the entire assembly. Its upper surface has multiple sets of guide grooves and hinge holes for positioning and installing other components. The left and right side frame welded components are located at both ends of the base, forming the left and right columns of the main support body. Their tops have multiple insertion holes for installing the crossbeams and limiting structures. The left and right center support assemblies are located in the middle area of ​​the base, connecting the central crossbeam and steel pipe respectively, providing central support. They are divided into upper and lower column structures by a hinge connecting plate located in the middle. The upper column of each central support assembly can rotate 180 degrees around the hinge connecting plate and overlap with the lower column, thereby compressing the overall height space when folded.

[0063] In the assembled state, the left and right side frames and the central support assembly are all inserted into the base guide grooves via guide keys and positioned and locked by hinge pins, forming a stable column structure. Diagonal braces connect the base to the left and right side frames respectively, enhancing lateral support rigidity and preventing structural swaying or deformation during use. The steel pipes are pluggable and installed in the column holes of the left, right, and central support assemblies, supporting irregularly shaped hydraulic steel pipe workpieces. Operators can flexibly adjust the number and position of the inserted steel pipes according to the size and quantity of the workpieces to achieve optimal support. The central crossbeam is installed between the tops of the left and right central support assemblies, and the welded crossbeam is connected to the tops of the left and right side frames. Together, they form the top connecting frame of the device, improving overall rigidity and facilitating manual handling, hoisting, and stable support.

[0064] During use, the operator first places the base on a flat surface, unfolds each column component in sequence, and inserts the guide keys into the guide slots on the base to complete the insertion and positioning. Then, the diagonal braces, steel pipes, intermediate crossbeams, and welded crossbeam components are installed to form a complete frame. Hydraulic steel pipe workpieces are placed sequentially on each inserted steel pipe, with buffer pads or limiting components added as needed to prevent rolling or compression deformation. During transport and recovery, the operator removes all steel pipes, crossbeams, and diagonal braces, pulls the guide keys on each column to disengage it from the guide slots, and the side frame and central support assembly can then rotate around the hinge pin to lie flat above the base. The upper column of the central support assembly rotates 180 degrees around the hinge connecting plate and overlaps with the lower column, then folds inward to fit against the base surface, forming a compact folded state. At this point, the overall height and lateral width of the transfer frame are significantly reduced, allowing for efficient stacking or loading for transport, significantly improving vehicle utilization and reducing transportation costs.

[0065] In this embodiment, the structural components can be made of high-strength carbon steel, stainless steel, or other metals with good weldability and impact resistance, meeting strength requirements while ensuring long-term durability. This transfer frame has a simple and reasonable structure, efficient assembly, and strong adaptability, making it widely applicable to the support and transportation needs of hydraulic steel pipes for excavators of different specifications. In practical engineering applications, this device has been verified to effectively reduce workpiece wear and improve operational efficiency, demonstrating significant potential for widespread application.

[0066] In summary, the excavator hydraulic steel pipe folding transfer frame provided by this utility model has a reasonable structure, which can effectively support and orderly store irregularly shaped hydraulic steel pipes, avoiding quality problems such as bumps and deformation during manufacturing, storage and transportation. Through the guide keys and hinge pins connecting the various support components, as well as the hinge folding structure of the central support column, the entire device can be quickly folded and retracted when unloaded, significantly reducing volume, saving transportation space, improving loading and unloading efficiency, and reducing transportation and turnover costs. The device has a simple structure, is easy to assemble, and has strong adaptability, possessing good engineering application value and promotion prospects.
