Abstract
Description
Technical Field
[0001] This utility model relates to the field of cargo inspection, specifically to a modular gantry frame. Background Technology
[0002] Gantry cranes are widely used in port loading and unloading, container yards, and other scenarios. Demand is rising with the growth of international trade, and the current overall technological development trend is towards modularization and lightweighting. However, commonly used gantry cranes generally suffer from problems such as the inability to be modularly produced and assembled, leading to inconvenient transportation, or fixed dimensions resulting in poor versatility.
[0003] To address this issue, modular design technologies for gantry cranes exist. One approach divides the gantry crane into vertical trusses, fixed sections, horizontal beam trusses, guardrail mechanisms, and lifting covers, using fixed sections to secure these components and form the gantry frame. Another approach folds the gantry frame and unfolds it by engaging different clips into support slots. While these technologies break down the gantry crane into components that can be assembled later, alleviating some of the problem of low modularity, their reliance on fixed sections or slots for assembly results in weak stability, making it easy for components to accidentally detach and cause damage. Therefore, these technologies have low stability and safety. Furthermore, the inability to extend the gantry's width and its limited versatility and flexibility remain drawbacks.
[0004] Therefore, there is a need to provide an improved modular gantry that can solve the problems and defects existing in the prior art. Utility Model Content
[0005] The purpose of this utility model is to provide a modular gantry frame that can be easily and stably assembled in a modular manner, and whose length can be adjusted to adapt to different installation environments.
[0006] According to this disclosure, a modular gantry frame is proposed, comprising: a frame including a transverse frame and a longitudinal frame perpendicular to each other, wherein the transverse frame includes a plurality of first rods connected in series with each other, and the longitudinal frame includes a plurality of second rods parallel to each other. Furthermore, the modular gantry frame also includes at least one first connector for interconnecting the first rods and a second connector for interconnecting the first rods and second rods, wherein the first connector has insertion portions at both ends inserted and fixed into opposite ends of two first rods, and the second connector has insertion portions at both ends inserted and fixed into opposite ends of the second rod and the first rod, wherein the length of the insertion portion of at least one of the first and second connectors is adjustable, such that the length of at least one of the transverse and longitudinal frames is adjustable.
[0007] In this way, the gantry is modularly broken down into smaller, more compact parts, significantly increasing the product's modularity and thus improving transport convenience. Furthermore, the adjustable lengths of the transverse and / or longitudinal frames allow for customization of the modular gantry's dimensions to suit different usage scenarios, enhancing its versatility and flexibility.
[0008] Furthermore, the components of the gantry frame are connected by bolts. Compared to snap-fit and mortise-and-tenon connections, bolt connections are more stable, thus preventing accidental detachment of the gantry frame components and improving the overall stability of the gantry frame.
[0009] According to another aspect of the present invention, the first connector has multiple sets of screw holes along its length, and each of the first rods has an adjustment hole at the end into which the first connector is inserted. The adjustment hole can be aligned with one set of screw holes. This design allows the first connector to be aligned with the screw holes and tightened at any adjustment hole, thereby achieving the goal of ensuring the stability of the connection between the first connector and the first rod while allowing adjustment of the length of the portion of the first connector inserted into the first rod.
[0010] According to another aspect of this invention, the first connector includes two first portions that are respectively inserted into the first rod as insertion parts, and a second portion located between the two first portions and not obstructed by the first rod. The modular gantry frame further includes one or more sleeves that fit over the second portion of the first connector, making the outer surface of the transverse frame flush. Since the first connector needs to be inserted into the first rod, its outer diameter is smaller than the outer diameter of the first rod; preferably, the outer diameter of the first connector is equal to the inner diameter of the first rod. Therefore, sleeves are provided to compensate for the difference in outer diameter between the first connector and the first rod, ensuring the overall dimensions of the assembled transverse frame are consistent. This is both aesthetically pleasing and strengthens the transverse frame at the smaller portion of the first connector.
[0011] According to another aspect of this utility model, the first rod is L-shaped, wherein the opposite ends of the two first rods are the opposite horizontal ends of the two first rods, and the opposite ends of the first rod and the second rod are the vertical ends of the first rod and the upper ends of the second rod. The L-shaped shape makes the connection between the first rod forming the horizontal frame and the second rod forming the vertical frame smoother.
[0012] According to another aspect of the present invention, the longitudinal end of the first rod and the upper end of the second rod are joined together, so that the outer surface of the longitudinal frame is flush.
[0013] According to another aspect of this invention, each of the plurality of second rods is connected to a ground cage at its lower end. The ground cage is buried underground to increase the grounding stability of the modular gantry. Preferably, the ground cage is also secured to the lower end of the second rod using fasteners such as bolts. Furthermore, it is preferable to use a larger ground cage, for example, one with a longitudinal length not less than one-quarter the length of the longitudinal frame of the modular gantry and a transverse width not less than one-fifth the length of the transverse frame of the modular gantry. This ensures that the longitudinal frame of the gantry is firmly grounded and will not accidentally shake, thus improving the stability of the device.
[0014] According to another aspect of this utility model, the frame, the first connecting member, and the second connecting member are hollow tubes, wherein each of the plurality of second rods has an inlet hole at its lower end, and wherein the frame includes a plurality of outlet holes. In this manner, cables for powering and communicating with electrical equipment mounted on the frame can enter the frame at the inlet hole, travel along the internal channels of the transverse and / or longitudinal frames, and exit the frame at the outlet hole to connect to the electrical equipment. This prevents cables from being exposed outside the frame of the modular gantry, effectively protecting the cables. Additionally, openings in the frame that are exposed to ambient air, such as adjustment holes not connected to other accessories and outlet holes, are sealed with sealants (such as rubber plugs, waterproof covers, etc.) to isolate the interior of the frame from the external ambient air, thereby preventing the gantry from being affected by changes in the external environment, such as preventing rain and snow from entering the interior of the gantry frame and causing short circuits in cables or damage to the mechanical properties of the frame. Therefore, the safety of the gantry of this utility model is further improved.
[0015] The first connector, the second connector, the sleeve, and the first and second rods constituting the frame are all standard parts, requiring no special customization. They can be hollow round tubes, hollow square tubes, or any other easily manufactured shape. Furthermore, the modular gantry frame is integrally formed into a bilaterally symmetrical axisymmetric shape, allowing for interchangeable positions of its components. There are no components with special positions or connection methods, significantly reducing assembly process requirements. Therefore, the modular gantry frame disclosed herein possesses a high degree of structural integrity and standardization.
[0016] According to another aspect of this utility model, the modular gantry also includes multiple information acquisition devices. The modular gantry further includes a slide rail fixed to a longitudinal frame and an information acquisition device mounting component installed to slide along the slide rail. The information acquisition devices are attached to the mounting component, and the information acquisition devices are attached to the mounting component via an angle adjustment component. The information acquisition devices can be, for example, cameras or radar, and the angle adjustment component can be a universal joint. Therefore, the information acquisition devices can move longitudinally relative to the modular gantry via the mounting component, and can move laterally and change angles relative to the mounting component via the angle adjustment component. The information acquisition devices are configured to allow information collection on goods and trucks passing through the modular gantry. The information acquisition devices are mounted to move vertically relative to the frame, and their angles can be adjusted via the angle adjustment component, allowing for real-time adjustment of the position and angle of the information acquisition devices according to actual needs, providing high flexibility.
[0017] According to another aspect of this invention, the modular gantry also includes a display device fixed to the top of the first pole. The display device can be an LED display screen or similar device, used to display user-customized information.
[0018] According to another aspect of this invention, the modular gantry also includes multiple lighting devices, which are respectively fixed to the transverse and longitudinal frames. The lighting devices are provided to overcome the problem of decreased recognition accuracy of the gantry in poor lighting conditions, and also to provide illumination for vehicles passing through the modular gantry, facilitating their passage.
[0019] This utility model's modular gantry uses multiple sections of rods to form the transverse and longitudinal frames. The gantry is assembled by using connectors that can be built into these rods and fixed in place by screws or bolts. This avoids non-removable fixing methods such as welding, while still ensuring that the various components of the gantry are firmly fixed in place in a convenient and quick manner. In addition, the length of the gantry frame can be adjusted by adjusting the length of the connectors inserted into the rods, so that the length of the gantry can be adapted to different working scenarios while ensuring reliable connection strength.

[0055] The following description of specific embodiments of this utility model refers to the accompanying drawings, which illustrate particular embodiments in which the utility model can be practiced. The embodiments are intended to describe various aspects of the utility model in sufficient detail to enable those skilled in the art to practice it. Other embodiments and changes may be utilized without departing from the scope of the utility model. Therefore, the following description of specific embodiments should not be considered limiting. The scope of this utility model is defined only by the appended claims and the full scope of their equivalents. The same reference numerals are used throughout the drawings and specific embodiments to refer to the same or similar parts.
[0056] The directional terms "lateral," "longitudinal," "up," "down," and "top" used in this article refer to the working position relative to the modular gantry 100 (e.g., ...). Figure 1 , Figure 2 The terms "outer" and "inner" are defined relative to the construction of the frame 101 of the modular gantry 100. The frame 101 is hollow and has cavities. Therefore, if component A is inside component B, component A is closer to the cavity of the frame 101, while component B is closer to the atmospheric environment in which the frame 101 is located. The lateral direction X is defined in the attached drawing as the direction extending horizontally from left to right, while the longitudinal direction Y is defined in the attached drawing as the direction extending vertically from bottom to top, perpendicular to the lateral direction X.
[0057] Figures 1 to 3 The diagrams show a perspective view, a front view, and an exploded view of the modular gantry 100 of the preferred embodiment of the present invention after assembly.
[0058] As shown in the attached figure, the modular gantry 100 generally includes: a frame 101 having a transverse frame 1 and a longitudinal frame 2 extending perpendicularly to each other; at least one first connector 5 and a plurality of second connectors 6, which are inserted and fixed into the frame 101 to connect and position the components of the frame 101; and various accessories attached to the frame 101, such as a ground cage 8, a display device 10, a lighting device 11, an information acquisition device 12, etc.
[0059] The transverse frame 1 is composed of a plurality of first rods 3 connected in series, and in this preferred embodiment, there are two first rods 3. Each first rod 3 is L-shaped, having a transverse portion extending in the transverse direction X and a longitudinal portion extending in the longitudinal direction Y perpendicular to the transverse direction X. The transverse portion terminates at a transverse end 31, and the longitudinal portion terminates at a longitudinal end 32. The transverse ends 31 of the two first rods 3 are opposite each other, and a first connector 5 is inserted and fixed at both ends into the transverse ends 31 of the two first rods 3. Thus, the first connector 5 assembles the two first rods 3 into the transverse frame 1.
[0060] The first connector 5 extends laterally and has multiple sets of screw holes along its lateral extension length; correspondingly, each of the first rods 3 has an adjustment hole 30 at its horizontal end 31 (i.e. the end into which the first connector 5 is inserted). These adjustment holes 30 can be selectively aligned with a set of screw holes 50 of the first connector 5 so as to be fixed by bolts or other fasteners.
[0061] Because the first connector 5 has multiple sets of screw holes, it can be inserted into the first rod 3 at different depths or lengths, aligning and fixing the corresponding screw holes 50 and adjusting holes 30. Thus, the first connector 5 has two first parts 51 inserted into the first rod 3 as insertion portions, and a second part sandwiched between the two first parts 51 that is not obstructed by the first rod 3. As shown in the attached figures, the length of the transverse frame 1 of the modular gantry 100 is composed of the length of the transverse portion of the first rod 3 and the second part of the first connector 5. Therefore, adjusting the length of the first part 51 of the first connector 5 is equivalent to adjusting the length of its second part, thereby allowing adjustment of the overall length of the transverse frame 1, i.e., the transverse width of the frame 101. In this way, the modular gantry 100 can adjust its transverse width according to different usage scenarios, improving the product's versatility.
[0062] Preferably, the modular gantry 100 also includes a sleeve 7 that encloses the second part of the first connector 5. Figure 4 The diagram shows the connection between the first connector 5 and the first rod 3, with the first rod 3 shown in perspective to clearly illustrate the insertion connection between the first connector 5 and the first rod 3. Figure 4As shown, the first connector 5 is partially inserted into the first rod 3 with its first part 51, and its second part, which is not inserted into the first rod 3, is fitted by a sleeve 7. The outer diameter of the sleeve 7 is fixed to be the same as the outer diameter of the first rod 3 so that the outer surface of the transverse frame 1 is flush after the sleeve 7 is installed. This is beneficial to the overall appearance of the product and also strengthens the frame 101 of the modular gantry 100 at the second part of the first connector 5.
[0063] Similarly, the sleeve 7 is also perforated to align with the threaded hole 50 of the first connector 5 for bolt tightening. To improve product standardization, such as... Figure 4 As shown, multiple sleeves 7 of the same length can be set, so that different numbers of sleeves 7 can be selected for fitting according to the length of the second part of the first connector 5, without the need to customize sleeves 7 of different lengths.
[0064] Although the transverse frame 1 in this preferred embodiment uses two L-shaped first rods 3 and one first connector 5, this disclosure is not limited thereto. In alternative embodiments, it is conceivable to use multiple first rods 3 of straight shape or other suitable shape, and multiple first connectors 5 that connect these first rods 3 in series. The connection relationship between the multiple first rods 3 and the multiple first connectors 5 is as described above, and the overall length of the transverse frame 1 can be adjusted by adjusting the depth of the insertion portion of the first connector 5 into the first rod 3.
[0065] The longitudinal frame 2 of the frame 101 of the modular gantry 100 includes a plurality of second rods 4 parallel to each other. In this preferred embodiment, two second rods 4 are included. Each of the two second rods 4 extends in the longitudinal direction Y and has an upper end 41 and a lower end 42. A plurality of second connectors 6 are provided to connect the second rods 4 to the first rods 3 of the transverse frame 1. Each of the second connectors 6 is inserted and fixed at both ends into the second rod 4 and the first rod 3, respectively, specifically into the upper end 41 of the second rod 4 and the longitudinal end 32 of the first rod 3.
[0066] Figure 5 A second connector 6 is shown, connecting a first rod 3 and a second rod 4 together. To clearly illustrate the connection, the first rod 3 and the second rod 4 are drawn in perspective view. It can be seen that, similar to the first connector 5, the second connector 6 has multiple sets of screw holes, while the longitudinal end 32 of the first rod 3 and the upper end 41 of the second rod 4 have corresponding sets of adjustment holes to align with the screw holes of the second connector 6. After assembly, the longitudinal end 32 of the first rod 3 is tightly abutted against the upper end 41 of the second rod 4, and the second connector 6 is completely concealed by the longitudinal end 32 of the first rod 3 and the upper end 41 of the second rod 4, residing inside the frame 101. Here, fasteners such as bolts and screws are used to secure the second connector 6 within the frame 101.
[0067] Although in this preferred embodiment, the second connector 6 is only used to connect the first rod 3 and the second rod 4 and is not used to adjust the size of the frame 101, this disclosure is not limited thereto. In alternative embodiments, it is conceivable that the second connector 6, similar to the first connector 5, can adjust the length of the portion inserted into the frame 101, thereby adjusting the length of the portion exposed outside the frame 101. Since the second connector 6 is arranged longitudinally, it mainly affects the length of the longitudinal frame 2, i.e., the longitudinal height of the frame 101. Therefore, it is conceivable that the longitudinal height of the frame 101 can be adjusted according to actual usage needs, further expanding the applicability of the product.
[0068] Although in this preferred embodiment, the first rod 3 constituting the transverse frame 1 is bent into an L-shape to facilitate the connection of the first rod 3 to the second rod 4 constituting the longitudinal frame 2 using a straight second connector 6, it is also conceivable in alternative embodiments that the first rod 3 is a horizontally extending straight rod and the second rod 4 is a longitudinally extending straight rod; instead of a straight second connector 6, the second connector 6 is shaped into an L-shape or a bent shape, with its horizontal end connected to the first rod 3 and its vertical end connected to the second rod 4, thereby connecting the first rod 3 and the second rod 4 perpendicularly to each other.
[0069] Furthermore, in this preferred embodiment, two parallel second rods 4 are used as the longitudinal frame 2. These two second rods 4 are respectively connected to the first rod 3 by means of second connectors 6, specifically to the longitudinal end 32 of the first rod 3, thereby assembling a complete frame 101. However, this disclosure is not limited to this, and in alternative embodiments, it is conceivable that each second rod 4 includes multiple second sub-rods connected end-to-end by means of connectors. This allows for a further reduction in the volume of the components of the modular gantry 100, facilitating transportation and carrying.
[0070] The frame 101 of the modular gantry 100, as well as the first connector 5 and the second connector 6, are preferably made of high-strength lightweight alloys, such as aluminum alloys, thereby reducing the weight of the product and also enhancing its durability.
[0071] As mentioned above, the modular assembly design of the Modular Gantry 100 allows for the transport of individual parts in a disassembled state, followed by reassembly into a complete gantry at the site of use. This reduces the transportation burden of the gantry and enhances its flexibility.
[0072] Additionally, the modular gantry 100 also includes ground cages 8. These ground cages 8 are buried underground to increase the stability of the modular gantry 100. Figure 6 As shown, each cage 8 is fastened to the lower end 42 of the second rod 4 of the longitudinal frame 2 using fasteners such as bolts.
[0073] Since the modular gantry 100 also houses electrical equipment such as display devices 10, lighting devices 11, and information acquisition devices 12, the robustness of the cabling providing communication and / or electrical connections for these devices also needs to be considered. Therefore, the frame 101 of the modular gantry 100, as well as the first connector 5 and the second connector 6, are all hollow tubes with cavities, and as... Figure 6 As shown, each second rod 4 has an inlet hole 91 at its lower end 42, and the frame 101 has multiple outlet holes 92 on its transverse frame 1 and longitudinal frame 2. In this way, cables can pass through the inlet holes 91 into the frame 101, pass through the cavity, and exit from the outlet holes 92 to connect to electrical equipment. For simplicity, Figure 1 and Figure 2 Only one outlet hole, 92, is marked.
[0074] In this way, the cables are routed inside the frame 101, thereby greatly reducing the exposure of cables and improving cable protection performance.
[0075] like Figure 1 and Figure 2 As shown, a display device 10 is mounted on top of the horizontal frame 1 of the modular gantry 100. The display device 10 is, for example, an LED display screen, and the displayed content can be customized, such as information about detected goods, information about the site where the gantry is used, etc. The display device 10 is fastened to the horizontal frame 1, especially to the first rod 3, using fastening methods such as snap-fit and bolt connection.
[0076] To facilitate operation in environments with low visibility, lighting devices 11 can also be provided. In this preferred embodiment, three lighting devices 11 are provided, as follows: Figure 1 and Figure 2 The light fixture 11 is fixed to the transverse frame 1 and the longitudinal frame 2, respectively. The light fixture 11 can use any suitable lighting tool, such as a strip light, a lamp tube, or a light bulb. Similarly, fasteners such as bolts are used to secure the light fixture 11 to the frame 101.
[0077] The modular gantry 100 also includes multiple information acquisition devices 12, such as cameras and radar, to allow information collection on trucks and cargo passing through the modular gantry 100. Preferably, multiple slide rails 13 are fastened to the longitudinal frame 2, and information acquisition device mounting pieces 14 are provided, which are mounted on the slide rails 13 and can be fixed or moved along the slide rails 13. The information acquisition devices 12 are attached to the information acquisition device mounting pieces 14, thereby moving relative to the longitudinal frame 2, allowing the position of the information acquisition devices 12 to be easily adjusted according to actual needs. Additionally, angle adjustment pieces 15, such as universal joints, can be added to the information acquisition devices 12 to allow for real-time adjustment of the angle of the information acquisition devices 12. For the sake of simplicity in the accompanying drawings, not all information acquisition devices 12 are labeled.
[0078] This utility model's modular gantry uses built-in connectors to quickly assemble the first and second rods into a frame. During the assembly process, only fasteners such as bolts are needed, without any welding operations. The length of the modular gantry frame, especially the length of the transverse frame, can be adjusted by adjusting the length of the connectors inserted into the frame, making the operation convenient. Therefore, it solves the problems of low modularity of existing gantry frames, which leads to inconvenient installation, and the inability to adjust the width, which leads to poor versatility.
[0079] As used herein, the terms “comprising,” “including,” “having,” or any other variation thereof are intended to cover non-exclusive inclusion. For example, a method, article, or apparatus that includes a list of elements is not necessarily limited to those elements and may also include other elements not expressly listed or inherent to the method, article, or apparatus.
[0080] This utility model is not limited to the above embodiments, which are merely illustrative and not restrictive. Those skilled in the art, under the guidance of this utility model, can make any possible changes and modifications without departing from the spirit and scope of the claims. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model, without departing from its scope of protection, fall within the scope defined by the claims.
