[0035] In the drawings, like parts are designated by like reference numerals. The drawings are not drawn to actual scale. Detailed implementation manners

[0036] The features and exemplary embodiments of various aspects of the present utility model will be described in detail below. In the following detailed description, many specific details are set forth in order to provide a thorough understanding of the present utility model. However, it will be apparent to those skilled in the art that the present utility model may be practiced without some of these specific details. The following description of the embodiments is only provided to better understand the present utility model by showing examples of the present utility model. In the drawings and the following description, at least some of the well - known structures and technologies are not shown in order to avoid unnecessarily obscuring the present utility model; and, for clarity, the dimensions of some structures may be exaggerated. In addition, the features, structures or characteristics described below may be combined in any suitable manner in one or more embodiments.

[0037] The directional terms appearing in the following description are all the directions shown in the drawings, and do not limit the specific structures of the gantry structure and the detection system of the present utility model. In the description of the present utility model, it should also be noted that, unless otherwise clearly specified and limited, the terms "mounted", "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be directly connected, or indirectly connected. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0038] In fields such as measurement channels, security checkpoints, highway intersections, etc., it is usually necessary to set up some components for dimension detection and prohibited item detection, such as external detection devices like imaging components, ray scanning components, etc. The external detection devices need to be fixed at a predetermined position through a support structure. The gantry structure, as the support for the external detection device, is widely used in the above - mentioned fields.

[0039] In the gantry structure in the related art, its various components are usually connected by on-site construction and welding or by vertical flanges. When the gantry is fixed to the ground, the position accuracy requirements for the ground cage are relatively high. For example, when there is an error between the fixed position of the first beam and the docking position of the second beam, the second beam cannot be assembled. Otherwise, sealing gaskets need to be added at the vertical flange connection. The assembly accuracy requirements for the gantry structure are high, increasing the construction difficulty.

[0040] To solve the above technical problems, an embodiment of the present application provides a new gantry structure and a detection system. The gantry structure can not only ensure the support requirements for external detection equipment, but also reduce its own assembly accuracy requirements, thereby reducing the construction difficulty.

[0041] To better understand the present utility model, the following combines Figures 1 to 6 The gantry structure and the detection system according to the embodiments of the present utility model are described in detail.

[0042] As Figures 1 to 3 As shown, an embodiment of the present application provides a gantry structure 100, including a frame body 10 and a connection assembly 20. The frame body 10 includes a first beam 12 and a second beam 11 intersecting with the first beam 12. The connection assembly 20 includes a first support 21 and a second support 22. The first support 21 is connected to the first beam 12 and the second support 22 is connected to the second beam 11. The first support 21 is connected to the second support 22 and their relative positions are adjustable.

[0043] The number of the first beam 12 and the second beam 11 can be one respectively, or can be two, three or more, and two are preferably selected.

[0044] The first support 21 and the first beam 12 can be connected by welding, an integral structure or a fastener connection. The second support 22 and the second beam 11 can be connected by welding, an integral structure or a fastener connection.

[0045] The first support 21 and the second support 22 can be connected by a fastener connection, a snap connection, etc. When their positions are adjusted to appropriate positions, they can be fixed by fastener locking or snap connection.

[0046] In an embodiment of the present application, the gantry structure 100 can support the second beam 11 to a predetermined height through the first beam 12. External detection devices 200 such as imaging components and ray scanning components can be installed on at least one of the second beam 11 and the first beam 12 to meet the detection requirements when the device to be detected passes through the gantry structure 100. Since a connection assembly 20 is provided between the first beam 12 and the second beam 11, the connection assembly 20 includes a first support 21 and a second support 22. The first support 21 is connected to the first beam 12 and the second support 22 is connected to the second beam 11. At the same time, the first support 21 and the second support 22 are connected and their relative positions are adjustable. Even when there is an error between the fixed position of the first beam 12 and the docking position of the second beam 11 during construction, the relative position between the first support 21 and the second support 22 can be adjusted to make up for it, reducing the assembly accuracy requirements of the gantry structure 100, thereby greatly reducing the on-site construction difficulty and improving the operation efficiency.

[0047] In some alternative embodiments, an embodiment of the present application provides a gantry structure 100. A first connection hole 211 is provided on the first support 21, and a second connection hole 221 is provided on the second support 22.

Of course, in some embodiments, the first connection hole 211 and the second connection hole 221 can also be made into strip-shaped holes extending along the length direction X. When the first connection hole 211 and the second connection hole 221 are both strip-shaped holes, their lengths can be equal, or the length of one can be greater than the length of the other.

[0052] In an embodiment of the present application, for the gantry structure 100, by making at least one of the first connection hole 211 and the second connection hole 221 a strip-shaped hole extending along the length direction X, when assembling the second beam 11 and the first beam 12 of the gantry structure 100, the first support 21 and the second support 22 can move relative to each other in the length direction X to an appropriate position and then be locked by the first fastener, so as to compensate for the error between the distance between the two outermost second beams 11 after installation and the length of the second beam 11, effectively reducing the assembly precision requirements of the gantry structure 100, and further greatly reducing the on-site construction difficulty and improving the operation efficiency.

[0053] In some optional embodiments, for the gantry structure 100 provided in an embodiment of the present application, the number of at least one of the first connection hole 211 and the second connection hole 221 is more than two and they are spaced apart in the length direction X.

[0054] The number of the first connection holes 211 can be more than two and at least some of the first connection holes 211 are spaced apart in the length direction X, or the number of the second connection holes 221 can be more than two and at least some of the second connection holes 221 are spaced apart in the length direction X. Of course, the number of the first connection holes 211 and the number of the second connection holes 221 can both be more than two and at least some of them are respectively spaced apart in the length direction X.

[0055] When the number of the first connection holes 211 is more than two, the two or more first connection holes 211 can be round holes or strip-shaped holes. At this time, the second connection hole 221 can be a round hole or a strip-shaped hole, and the number of the second connection holes 221 can be one or more than two.

At the same time, when the number of both the first connection holes 211 and the second connection holes 221 is more than two, they can be connected and fixed by multiple first fasteners, and can also improve the connection strength and connection stability between the second beam 11 and the first beam 12.

[0058] Such as Figures 1 to 3As shown, in some alternative embodiments, for the gantry structure 100 provided by an embodiment of the present application, the number of the first beams 12 is more than two, and the two or more first beams 12 are spaced apart along the length direction X of the second beam 11. In the length direction X, at least one of the outermost first beams 12 and the second beam 11 are provided with a connection assembly 20.

[0059] The number of the first beams 12 is more than two and they are spaced apart along the length direction X of the second beam 11. At least one of the second beam 11 and the first beams 12 is used for connecting with an external detection device 200. In the length direction X, a connection assembly 20 is provided between at least one of the outermost first beams 12 and the second beam 11.

[0062] Through the above arrangement, it is beneficial to adjust the assembly position between the first beam 12 and the second beam 11 and reduce the assembly difficulty between the two.

[0063] In some alternative embodiments, for the gantry structure 100 provided by an embodiment of the present application, the length of the second beam 11 can be D2, and the inner facade distance between the two first beams 12 is D1. For the convenience of installation, during design, D2 < D1, that is, a gap L1 = (D1 - D2) / 2 is reserved between the second beam 11 and the first beam 12, so that both ends of the second beam 11 have a certain degree of position adjustment freedom relative to the paired first beams 12, effectively reducing the assembly difficulty.

[0064] In some alternative embodiments, for the gantry structure 100 provided by an embodiment of the present application, when the first connection hole 211 or the second connection hole 221 is a strip-shaped hole, the strip-shaped hole can include a straight hole section and semi-circular hole sections located on both sides of the two straight hole ends. The vertical distance between the centers of the two semi-circular hole sections in the length direction X is c, and the distance tolerance between the paired first beams 12 can be between (-c, +c) to ensure the assembly requirements between the second beam 11 and the paired first beams 12.

[0070] The reinforcing plate 131 and the portion of the first support 21 protruding from the first beam 12 and the first beam 12 may be connected by welding or the like.

[0071] In a portal frame structure 100 provided by an embodiment of the present application, the reinforcement component 13 includes a plurality of reinforcement plates 131.

[0089] As Figure 6 shown, on the other hand, an embodiment of the present application also provides a detection system, including the gantry structure 100 provided by any one of the above embodiments and an external detection device 200. The external detection device 200 is disposed on and connected to the gantry structure 100. The external detection device 200 includes, but is not limited to, an imaging component, a ray scanning component, an illumination component, etc.

[0090] During use, the device to be detected can pass through the space formed by the second beam 11 and the first beam 12. During the passing process, the external detection device 200 can perform detections such as imaging on the device to be detected.

[0091] The number of the external detection devices 200 can be one or multiple. The external detection device 200 can be provided on the second beam 11, can be provided on the first beam 12. Of course, the external detection device 200 can also be provided on both the second beam 11 and the first beam 12.

[0092] A detection system provided by an embodiment of the present application can be used in fields such as measurement channels, security checkpoints, highway intersections, etc. Since it includes the gantry structure 100 and the external detection device 200 provided in the above embodiments, the second beam 11 can be supported to a predetermined height by the first beam 12, and the external detection device 200 such as an imaging component and a ray scanning component can be installed on at least one of the second beam 11 and the first beam 12 to meet the detection requirements when the external detection device 200 passes through the gantry structure 100. Since a connection assembly 20 is provided between the first beam 12 and the second beam 11, the connection assembly 20 includes a first support 21 and a second support 22. The first support 21 is connected to the first beam 12 and the second support 22 is connected to the second beam 11. At the same time, the first support 21 and the second support 22 are connected and their relative positions are adjustable, so that even when there is an error between the fixed position of the first beam 12 and the docking position of the second beam 11 during construction, the relative positions of the first support 21 and the second support 22 can be adjusted to make up for it, reducing the assembly accuracy requirements of the gantry structure 100, thereby greatly reducing the on-site construction difficulty and improving the operation efficiency.

[0093] Although the present invention has been described with reference to the preferred embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way. The present invention is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
