Abstract
Description
Technical Field
[0001] This utility model relates to the field of sliding contact line structure technology, specifically a sliding contact line structure with lower temperature rise. Background Technology
[0002] Mobile devices need to constantly change positions due to their movement. At each different position, the mobile device must be able to obtain power at any time, otherwise it will not be able to continue moving. Therefore, a sliding contact line structure is needed to move it.
[0003] However, existing technologies still have many defects in some similar structures when used in practice. For example, problems such as poor contact or insulation damage caused by vibration of the sliding contact line can cause electric shock to operators when they touch the sliding contact line or related equipment, resulting in personal injury. At the same time, the connection points of the sliding contact line with other equipment or components need to be stably supported. If the support is insufficient, the connection parts may loosen or fall off due to excessive force, affecting the normal operation of the sliding contact line and even causing safety accidents.
[0004] To address the aforementioned problems, the inventors proposed a sliding contact line structure with lower temperature rise. Utility Model Content
[0005] In order to solve the problems of the inability to reduce the impact force on the conductor rail due to vibration and the inconvenience of supporting the conductor rail, the purpose of this utility model is to provide a conductor rail structure with a lower temperature rise.
[0006] To solve the above technical problems, the present invention adopts the following technical solution: a sliding contact line structure with low temperature rise, comprising a line body, both ends of which are fixedly connected to buffer devices, and the bottom surface of the line body is fixedly connected to multiple support devices distributed at equal intervals. Each support device includes symmetrically distributed brackets, the ends of two brackets are respectively fixedly connected to connecting frames, the outer surfaces of the two lower connecting frames are jointly fitted with connecting plates, and the outer surfaces of the two upper connecting frames are respectively fitted with fixing plates.
[0007] As a preferred technical solution of this application, the buffer device includes a support plate, a plurality of support rods are fixedly connected to one side of the support plate, a positioning plate is fixedly sleeved on the outer surface of the support rod, and a spring is sleeved on the outer surface of the support rod.
[0008] With the above technical solution, when an external force is applied to the support plate, the support plate will compress and stretch the spring. The spring absorbs energy through elastic deformation and plays a buffering role. When the line is subjected to sudden tension and pressure, the spring will be stretched and compressed accordingly, reducing the instantaneous impact force on the line and effectively reducing the impact force received by the sliding contact line due to vibration.
[0009] As a preferred technical solution of this application, each of the two brackets has two semi-circular plates at one end, and the outer surfaces of the two semi-circular plates are provided with through grooves. The inner walls of the two through grooves are rotatably connected to a rotating shaft. The outer surfaces of the two rotating shafts are fitted with hollow sleeves, and the outer surfaces of the two hollow sleeves are fixedly connected to a support rod.
[0010] Through the above technical solution, the support rod can rotate at a certain angle within the through groove of the semi-circular plate via a rotating shaft, adapting to changes in the production line and ensuring its stability.
[0011] As a preferred technical solution of this application, the top surface of the connecting plate is fixedly connected to the line body.
[0012] The above technical solution can make the line more stable.
[0013] As a preferred technical solution of this application, the top surface of the fixing plate is symmetrically threaded with bolts.
[0014] Through the above technical solution, bolts can fix the support device to the equipment, further enhancing the stability of the entire sliding conductor rail structure.
[0015] As a preferred technical solution of this application, the two ends of the spring are fixedly connected to one side of the opposite surface of the support plate and the positioning plate, respectively.
[0016] Through the above technical solution, the spring absorbs energy through elastic deformation, playing a buffering role. When the line is subjected to sudden tension and pressure, the spring will be stretched and compressed accordingly.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] 1. This utility model can achieve the purpose of effectively reducing the impact force on the sliding contact line due to vibration when an external force is applied to the support plate. When an external force is applied to the support plate, the support plate will compress and stretch the spring. The spring absorbs energy through elastic deformation and plays a buffering role. When the line is subjected to sudden tension and pressure, the spring will be stretched and compressed accordingly, reducing the instantaneous impact force on the line.
[0019] 2. This utility model allows the support rod to rotate at a certain angle within the through groove of the semi-circular plate when the conductor undergoes slight displacement during operation. This adapts to changes in the conductor and ensures its stability, thereby effectively supporting the sliding contact line. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Example: Figure 1-4 As shown, this utility model provides a sliding contact line structure with low temperature rise, including a line body 1. Both ends of the line body 1 are fixedly connected to buffer devices 2. The bottom surface of the line body 1 is fixedly connected to multiple support devices 3 distributed at equal intervals. The support devices 3 include symmetrically distributed brackets 31. The two ends of the two brackets 31 are respectively fixedly connected to connecting frames 32. The outer surfaces of the two lower connecting frames 32 are jointly fitted with connecting plates 33. The top surface of the connecting plates 33 is fixedly connected to the line body 1. The outer surfaces of the two upper connecting frames 32 are respectively fitted with fixing plates 34. The top surfaces of the fixing plates 34 are symmetrically threaded with bolts.
[0028] Through the cooperation of the connecting frame 32 and the connecting plate 33, the supporting force is transferred from the bracket 31 to the line body 1, which plays the role of supporting the line body. The bolts can fix the support device 3 to the equipment, further enhancing the stability of the entire sliding contact line structure.
[0029] The buffer device 2 includes a support plate 21. A plurality of support rods 22 are fixedly connected to one side of the support plate 21. A positioning plate 23 is fixedly sleeved on the outer surface of the support rod 22. A spring 24 is sleeved on the outer surface of the support rod 22. The two ends of the spring 24 are fixedly connected to one side of the opposite surface of the support plate 21 and the positioning plate 23, respectively.
[0030] When an external force is applied to the support plate 21, the support plate 21 will compress and stretch the spring 24. The spring 24 absorbs energy through elastic deformation and plays a buffering role. When the line is subjected to sudden tension and pressure, the spring 24 will be stretched and compressed accordingly, reducing the instantaneous impact force on the line and effectively reducing the impact force received by the sliding contact line due to vibration.
[0031] Two semicircular plates 35 are provided at one end of each of the two brackets 31. The outer surfaces of the two semicircular plates 35 are provided with through grooves 36. The inner walls of the two through grooves 36 are rotatably connected to a rotating shaft 37. Hollow sleeves 38 are fitted onto the outer surfaces of the two rotating shafts 37. Support rods 39 are fixedly connected to the outer surfaces of the two hollow sleeves 38.
[0032] When the conductor 1 undergoes a slight displacement during operation, the support rod 39 can rotate at a certain angle within the through groove 36 of the semicircular plate 35 via the rotating shaft 37 to adapt to the changes in the conductor 1, ensure the stability of the conductor 1, and effectively support the sliding contact line.
[0033] The working principle of a sliding contact line structure with low temperature rise in this embodiment is as follows: The support plate 21 in the buffer device 2 is the main force-bearing component. When the line 1 is subjected to external force, the external force is transmitted to the support plate 21. Multiple support rods 22 provide support for the positioning plate 23 and the spring 24. The positioning plate 23 is sleeved on the outer surface of the support rod 22 and acts as a positioning spring 24. The spring 24 is sleeved on the outer surface of the support rod 22. When an external force is applied to the support plate 21, the support plate 21 will compress and stretch the spring 24. The spring 24 absorbs energy through elastic deformation and plays a buffering role. When the line is subjected to sudden tension and pressure, the spring 24 will be stretched and compressed accordingly, reducing the instantaneous impact force borne by the line, thereby achieving the purpose of effectively reducing the impact force received by the sliding contact line due to vibration.
[0034] Through the cooperation of the connecting frame 32 and the connecting plate 33, the supporting force is transferred from the bracket 31 to the conductor 1, which plays the role of supporting the conductor. The bolts can fix the support device 3 to the equipment, further enhancing the stability of the entire sliding contact line structure. When the conductor 1 undergoes a slight displacement during operation, the support rod 39 can rotate at a certain angle in the through groove 36 of the semi-circular plate 35 through the rotating shaft 37 to adapt to the changes in the conductor 1 and ensure the stability of the conductor 1, thereby achieving the purpose of effectively supporting the sliding contact line.
[0035] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
