[0034] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0035] The core of the utility model is to provide a bogie frame and an engineering inspection vehicle, which greatly compresses the vertical size of the bogie frame while ensuring the strength of the bogie frame itself, providing space for installing large equipment under the bogie frame.

[0036] In order to enable those skilled in the art to better understand the technical solution provided by the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] Specifically, please refer to Figures 1-6 The present invention provides a bogie frame A, comprising two side beams 100 and a cross beam 200 connected between the two side beams 100. The two side beams 100 and the cross beam 200 are welded together to form an H-shaped structure as a whole.

[0038] like Figure 3 As shown, each side member 100 is a flat structure, comprising a hollow spring mounting base 130, and a first half-beam 110 and a second half-beam 120 connected to either side of the hollow spring mounting base 130. The hollow spring mounting base 130 is a one-piece forging. It should be noted that, unlike conventional side members that feature a recessed center for mounting hollow springs, the center section of the side member has the largest cross-section, designed to carry vertical loads.

[0039] The overall shape of the side beam in the present application is changed to a flat structure, and the middle load-bearing position (i.e., the empty spring mounting seat 130) is made of forgings. Under the premise of ensuring strength, the vertical size of the side beam is greatly reduced, and space for installing equipment is reserved. NDT equipment can be installed in the reserved installation space to realize the NDT function. It can also make the entire integrated bogie a complete module, which can be interchanged with ordinary bogies as a whole, facilitating vehicle design.

[0040] The crossbeam 200 comprises two transverse beams and two longitudinal beams. Each transverse beam is connected to two side beams 100 at both ends, and each longitudinal beam is connected to two transverse beams at both ends. The two transverse beams and two longitudinal beams form a crisscross pattern. The crisscross pattern has a through-groove running vertically through the center, which can be used to accommodate a traction device. By optimizing the traction device's structure and compressing its vertical dimensions, sufficient space is reserved for the lower portion of the bogie. A longitudinal stop seat 210 is provided on the inner side of each transverse beam, specifically within the through-groove of the crisscross pattern. A brake hanger 220 for mounting a brake device is provided on the outer side of each transverse beam. The transverse beams are box-shaped, and each longitudinal beam is provided with a transverse stop rib 230 on the outer side. The longitudinal beams are I-shaped. The primary function of the transverse stop rib 230 on the bogie is to prevent excessive lateral displacement between the bogie and the vehicle body when negotiating curves.

[0041] Specifically, the crossbeam 200 can be welded together from an upper cover plate, a lower cover plate, and vertical plates, forming a crisscross pattern. Specifically, the transverse beam primarily comprises the upper and lower cover plates, with vertical plates positioned on either side of the upper and lower cover plates, forming a box-shaped structure that enhances structural strength. The longitudinal beam primarily comprises the upper and lower cover plates, with vertical plates positioned on the inner sides of the upper and lower cover plates, forming an I-shaped structure that reduces weight at the longitudinal beam.

[0042] Compared with the cross beam 200, the structural change of the side beam 100 is more obvious in the vertical dimension compression, such as Figure 3 As shown, by optimizing the structures of the side beams 100 and cross beams 200 of the bogie frame A, and adaptively selecting and optimizing the corresponding empty springs and traction devices, it is possible to meet the requirements of vertically installing inspection equipment such as flaw detection equipment B on the bogie frame A (e.g. Figure 5 and Figure 6 shown).

[0043] The bogie frame A provided by the present invention features a straight overall design for the side beams 100. The empty spring mounting seats 130 on the side beams 100 are forged. This significantly reduces the vertical dimensions of the side beams 100 while ensuring strength, leaving space for the installation of flaw detection equipment. A crossbeam 200 is positioned between the two side beams 100. The crossbeam 200 comprises two transverse beams and two longitudinal beams in a crisscross configuration. The transverse beams are box-shaped, each with a longitudinal stop seat 210 positioned on its inner side. Each transverse beam has a brake hanger 220 positioned on its outer side for mounting a brake device. The longitudinal beams are I-shaped, each with a transverse stop rib 230 positioned on its outer side. The crossbeam 200 utilizes a combination of box and I beams to create a crisscross configuration. The center of the crisscross configuration can be used to accommodate a traction device. By optimizing the traction device's structure and reducing its vertical dimensions, sufficient space is reserved for the lower portion of the bogie. By optimizing the structures of the side beams 100 and cross beams 200 of the bogie frame A, the vertical dimensions and overall weight of the entire bogie frame A are greatly reduced, leaving sufficient space for installing equipment below the bogie frame A.

[0044] In a specific embodiment, the first half beam 110 and the second half beam 120 are straight box-shaped half beams. The side beam 100 has a three-section structure, with the ends of the hollow spring mounting base 130 welded to the two straight box-shaped half beams, further reducing the vertical size of the side beam 100.

[0045] The empty spring mounting seat 130 can be designed as an integrally formed forging. Simultaneously, a mounting groove can be provided above the empty spring mounting seat 130 and a reinforcing rib can be provided below the empty spring mounting seat 130.

[0046] The above arrangement allows forgings to meet strength requirements with smaller structural dimensions than welded steel plates, making flatter designs possible. The addition of ribs further reduces forging weight while still meeting strength requirements, achieving the goal of lightweight design.

[0047] In order to achieve the stability of the connection, the hollow spring mounting seat 130 is welded to the first half beam 110 and the second half beam 120. The ends of the hollow spring mounting seat 130 are welded to the straight half beams of the box structure on both sides, further reducing the vertical size of the side beam.

[0048] In a specific implementation, a first-order vertical shock absorber mounting seat 140, a swing arm positioning seat 150, and an anti-snaking shock absorber seat 160 are provided on the side of the side beam 100. The first-order vertical shock absorber mounting seat 140 and the anti-snaking shock absorber seat 160 are connected to the first half beam 110 / second half beam 120 via a rib plate. In particular, when the first half beam 110 / second half beam 120 is a box-type half beam consisting of an upper cover plate and a lower cover plate, the upper cover plate and the lower cover plate are connected via a rib plate, and a mounting position is provided for the first-order vertical shock absorber mounting seat 140 / anti-snaking shock absorber seat 160. Figure 2 It can be seen that there are two anti-snaking damper seats 160 and four primary vertical damper mounting seats 140 on a bogie frame A, and the first half beam 110 and the second half beam 120 are both provided with a primary vertical damper mounting seat 140.

[0049] In a specific embodiment, the two side beams 100 are symmetrically arranged, and the two side beams 100 are mirror images of each other.

[0050] The upper surfaces of the first half beam 110 and / or the second half beam 120 are provided with transverse vibration damper mounts 300 and lifting lugs 400. Equipment safety lifting lugs 600 are provided on the sides of the first half beam 110 and / or the second half beam 120. A height valve mounting seat 500 is provided on the outer side of the crossbeam 200. Mounting holes or mounting locations can be provided on the transverse vibration damper mounts 300, lifting lugs 400, equipment safety lifting lugs 600, and height valve mounting seat 500.

[0051] In summary, by redesigning the structure of bogie frame A, the present invention significantly reduces the vertical dimensions of bogie frame A while maintaining strength, providing space for installing large equipment underneath. The design of bogie frame A facilitates the integration of the bogie and testing equipment, saving installation space for under-vehicle equipment. Subsequent vehicle development can also utilize the bogie frame designed in this invention as the bogie body, enabling modular replacement without requiring a complete bogie redesign.

[0052] The present invention also provides an engineering inspection vehicle, including the bogie frame A described in the above-mentioned embodiment. Specifically, the bogie frame A can be a Type B bogie frame. This engineering inspection vehicle is not an ordinary passenger rail vehicle, but rather an engineering inspection vehicle for inspecting and repairing rail lines. Of course, the bogie frame A can also be applied to other types of engineering inspection vehicles, which will not be discussed here.

[0053] Obviously, the engineering inspection vehicle including the above-mentioned bogie frame has the same beneficial effects, which will not be described in detail here.
