Embodiment 1

[0035] like Figure 4 As shown in the figure, urban underground logistics vehicles operate in underground pipelines, and drainage ditches for draining sewage or accumulated water are usually set in the pipelines. In the present invention, the top of the drainage ditch is used as the running surface 81 , and the side wall of the drainage ditch is used as the guide surface 82 .

[0036] The present invention provides a beam-type bogie frame, such as Figure 1 to Figure 3 As shown, it includes a beam-type frame, and the beam-type frame includes a longitudinal beam 10 , a cross beam 11 and a connecting beam 12 . The longitudinal beam 10 includes a first straight section 101 , a second straight section 102 and a third straight section 103 , the middle of the longitudinal beam 10 is the third straight section 103 , and both ends of the longitudinal beam 10 are the first flat section 103 . For the straight section 101 , the first straight section 101 at both ends is symmetrically a...

Embodiment 2

[0042] The present invention also provides a beam-type bogie, such as Figure 1 to Figure 3 As shown, it includes the beam-type bogie frame, the running wheel 20 and the guide wheel 30 in the above-mentioned embodiment. A wheel axle 24 is connected between the running wheel frame 13 at the bottom of the second straight section 102 between the two longitudinal beams 10 through a bearing, and the wheel axle 24 is connected to the running wheel 20 after extending outward. As a power bogie, the beam-type bogie frame is also connected with a drive motor 21 for driving the traveling wheels 20 to travel. The drive motor 21 is connected with a gear box 23 through a coupling 22. The drive motor 21 drives the gear box 23 to run, and the gear box 23 runs. The box 23 drives the traveling wheel 20 to travel through the axle 24 .

[0043] like Figure 1 to Figure 3 As shown, specifically, two supporting plates 211 are connected on both sides of the driving motor 21 by welding or bolting, ...

Abstract

The invention discloses a beam-type bogie frame and a beam-type bogie, which relate to the technical field of underground pipeline transportation and solve the technical problem that the existing underground pipeline transportation vehicle's bogie relies on guide rails to travel and has a large external dimension. It includes a beam-type frame, the beam-type frame is connected with a bolster for connecting with the vehicle body, and the two bottoms of the beam-type frame are respectively provided with a running part and a guide part. The invention cleverly uses the drainage ditch in the pipeline as the guide rail of the bogie, installs running wheels through the running parts at the bottoms of the two sides of the beam-type frame, and then walks on the running surface of the drainage ditch. After the guide wheel is installed at the first part, it walks on the guide surface of the drainage ditch, and there is no need to set additional guide rails. In addition, the overall size of the bogie is reduced by the reasonable arrangement of the beam frame itself and the bolster, spring assembly, shock absorber and current receiver on the beam frame, which is beneficial to the overall design of the underground pipeline.

Description

technical field [0001] The invention relates to the technical field of underground pipeline transportation, in particular to a beam-type bogie frame and a beam-type bogie. Background technique [0002] With the increasing development of urban underground logistics system, the design of underground pipeline transportation vehicles has gradually become an important research topic. In the prior art, when the urban underground logistics vehicle is running in the underground pipeline, the wheels on the vehicle bogie usually adopt the rubber wheel structure, which can effectively reduce the impact force on the pipeline when the vehicle is running. However, the wheels using the rubber wheel structure need to be provided with guide wheels on the vehicle, which requires a separate guide rail for guiding the guide wheels in the pipeline. The design and construction of the guide wheels and the guide rails are complicated, and the number of guide rails is also increased. construction c...
