Description

Technical Field

[0001] The utility model relates to the technical field of self - propelled trolley tracks, in particular to a self - propelled trolley guide rail. Background Art

[0002] A self - propelled trolley mainly refers to a small vehicle that can walk autonomously or move according to a certain control method. Compared with traditional manual handling or fixed equipment, it can not only complete the handling task independently, reduce manual intervention, improve the degree of automation and handling efficiency, but also reduce the labor intensity of workers, and is widely used in many fields such as industrial automation, warehousing logistics, and military transportation.

[0003] As the infrastructure of the self - propelled trolley, the self - propelled trolley track provides a stable driving path and guidance for the self - propelled trolley. According to different application scenarios and requirements, different types of track materials and structures can be used for the self - propelled trolley track. Common track materials include steel rails, aluminum alloy tracks, etc. Among them, steel rails are widely used in heavy - load and high - speed operation occasions due to their high strength and strong load - bearing capacity, while aluminum alloy tracks are widely used in light - load and high - aesthetics - required places due to their beautiful appearance, corrosion resistance, and wear resistance.

[0004] However, with the progress of technology, the self - propelled trolley is constantly changing, and its walking mode has also changed. It has changed from the traditional riding - type walking to the flange - type walking. The traditional track is still suitable for the riding - type walking track and is not suitable for the new flange - type self - propelled trolley. If the flange - type self - propelled trolley is forced to run on the traditional track, not only can its due speed and stability advantages not be exerted, but also unnecessary damage may be caused to the trolley itself and the track. Summary of the Utility Model

[0005] The utility model provides a self - propelled trolley guide rail to solve the technical problem that the traditional track in the prior art cannot meet the walking requirements of the flange - type self - propelled trolley.

[0006] To solve the above problems, the self - propelled trolley guide rail provided by the utility model adopts the following technical solutions:

[0007] A self - propelled trolley guide rail, comprising:

[0008] A guide rail main body, which comprises a plurality of interconnected guide rail segments;

[0009] A guide rail segment, whose cross - section is in an I - shape. The guide rail segment includes an upper support plate and a lower support plate arranged in parallel, and the upper support plate and the lower support plate are connected by a web;

[0010] The area enclosed by the web, the upper support plate, and the lower support plate is a running wheel track;

[0011] The two ends of the upper support plate away from the web are guide wheel tracks, and the two ends of the lower support plate away from the web are also guide wheel tracks.

[0012] The beneficial effects of the self-propelled trolley guide rail provided by the present utility model are as follows:

[0013] 1. By designing the cross-section of the rail section as an I-shaped, the area enclosed by the upper support plate, the lower support plate and the web is used as the running wheel track, the two ends of the upper support plate away from the web are used as guide wheel tracks, and the two ends of the lower support plate away from the web are also used as guide wheel tracks. At the same time, it provides a running track for the running wheels and guide wheels of the self-propelled trolley. This structural design provides a special track form for the trolley with flange-type running, and realizes the compactness of the guide rail structure. It not only saves space, but also helps to reduce the weight of the entire self-propelled trolley running system and improve the running efficiency;

[0014] 2. The bent rail section is cold-pressed and integrally formed, which can ensure that it can be evenly stressed during the forming process, avoiding problems such as uneven internal stress and tissue change of the material caused by traditional hot processing. Thus, it ensures that the manufactured bent rail section has no deformation or distortion phenomenon, making it more beautiful and having a longer service life.

[0015] Through the above settings, the present utility model effectively solves the technical problem that the traditional track in the prior art cannot meet the running of the flange-type self-propelled trolley.

[0016] Furthermore, the rail section is an aluminum rail.

[0017] Beneficial effects: The aluminum rail has the advantages of light weight, high strength and good wear resistance, making it easy to transport and install, and capable of bearing a greater weight, and still maintaining a good appearance and performance during long-term use.

[0018] Furthermore, the rail section is a straight rail section or a bent rail section.

[0019] Furthermore, the bent rail section is cold-pressed and integrally formed.

[0020] Furthermore, the rail section is suspended under the auxiliary beam through a rail connection seat.

[0021] Furthermore, two upper mounting grooves opening upwards are respectively provided at both ends of the top surface of the upper support plate.

[0022] Furthermore, an upper weight reduction hole for reducing the weight of the rail section is provided between the two upper mounting grooves.

[0023] Furthermore, two lower mounting grooves opening downwards are respectively provided at both ends of the bottom surface of the lower support plate.

[0024] Further, a lower weight-reducing hole for reducing the weight of the guide rail section is formed between the two lower mounting grooves.

[0025] Further, an electrical mounting groove is also formed on the lower mounting plate. Description of the Drawings
