Description

Technical Field

[0001] This utility model relates to the field of sliding contact line technology, specifically an adaptive tensioning sliding contact line device. Background Technology

[0002] A sliding contact line is a power transmission device used to supply power to mobile equipment. It is also called a sliding conductor. It mainly consists of three main components: sheath, conductor, and current collector, as well as some auxiliary components. Its working principle is to lay several conductors parallel to the running track of the mobile equipment and connect them to the power supply. A current collector is installed on the mobile equipment. When the equipment moves, the current collector runs synchronously and draws power from the conductor.

[0003] In existing technologies, tensioners are typically used to apply tension to the sliding contact line so that it can maintain appropriate tension to ensure stable power transmission. However, the tension of common tensioners usually needs to be adjusted manually, and the tension is relatively fixed after adjustment. When the tension of the tensioner is too large, it is easy to break the sliding contact line, thereby affecting the stable power transmission.

[0004] Therefore, this invention provides an adaptive tensioning sliding contact line device to solve the above problems. Utility Model Content

[0022] 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.

[0023] This utility model provides an adaptive tensioning sliding contact line device, such as... Figure 1 , Figure 3 and Figure 4 As shown, the system includes a fixed plate 1, a connecting plate 2 fixedly connected to one side of the fixed plate 1, an mounting plate 5 provided on one side of the connecting plate 2, a mounting block 7 fixedly connected to one side of the mounting plate 5, a sliding rod 8 fixedly connected to the mounting block 7, a spring 9 sleeved on the side surface of the sliding rod 8, a first slider 10 slidably connected to the side surface of the sliding rod 8, a through hole 13 opened at the center of the mounting plate 5, a threaded rod 14 inserted into the through hole 13, a second slider 12 and a sliding contact line mounting box 15 respectively sleeved on the side surface of the threaded rod 14, the second slider 12 and the sliding contact line mounting box 15 are respectively located on both sides of the mounting plate 5, a connecting strip 11 is hinged to one side of the second slider 12, and the end of the connecting strip 11 away from the second slider 12 is hinged to one side of the first slider 10.

[0024] One end of the spring 9 is fixedly connected to one side of the mounting block 7, and the other end of the spring 9 is fixedly connected to one side of the first slider 10.

[0025] A first nut 16 is screwed onto the side surface of the threaded rod 14, and a rubber pad 17 is fitted onto the side surface of the threaded rod 14. One side of the rubber pad 17 is in contact with one side of the first nut 16, and the other side of the rubber pad 17 is in contact with one side of the second slider 12.

[0026] A second nut 18 is screwed onto the side surface of the threaded rod 14, and one side of the second nut 18 is in contact with one side of the sliding contact line mounting box 15.

[0027] The sliding contact line mounting box 15 of this device is used to fix the sliding contact line. After the sliding contact line is fixed, the sliding contact line mounting box 15 needs to be installed on the threaded rod 14. There are two threaded rods 14, and each threaded rod 14 has at least two second nuts 18, located on both sides of the sliding contact line mounting box 15, both used to fix the sliding contact line mounting box 15. After the two second nuts 18 come into contact with the sliding contact line mounting box 15 by rotation, the sliding contact line mounting box 15 can be fixed. After the sliding contact line mounting box 15 is fixed, the threaded rod 14 needs to pass through the mounting plate 5 and the second slider 12 in sequence, and then the first nut 16 is rotated to tension the sliding contact line. The rubber pad 17 is provided to... The first nut 16 and the second slider 12 provide a buffering effect, reducing the possibility of wear on the second slider 12 when the first nut 16 rotates, and improving the service life of the second slider 12. When the first nut 16 presses the second slider 12, the second slider 12 can slide on the threaded rod 14. When the second slider 12 slides, it can drive the first slider 10 to slide on the slide rod 8 through the connecting bar 11. When the first slider 10 slides, it will compress the spring 9. After the spring 9 is compressed, it will apply a reaction force to the first slider 10. This reaction force can be transmitted to the second slider 12 through the connecting bar 11, so that the second slider 12 can push the first nut 16.

[0028] During the tensioning of the sliding contact line, when the tension on the sliding contact line is too great, the first nut 16 will squeeze the second slider 12, thereby compressing the spring 9, providing buffer space for the sliding contact line, and reducing the possibility of the sliding contact line being pulled apart. In actual use, the operator can adjust the tightness of the first nut 16 as needed.

[0029] Furthermore, in order to improve the stability of the device, such as Figure 1 and Figure 2 As shown, the fixing plate 1 has multiple first fixing holes. A reinforcing plate 3 is fixedly connected to the side of the fixing plate 1 near the connecting plate 2. One side of the reinforcing plate 3 is fixedly connected to the side of the connecting plate 2 away from the mounting plate 5.

[0030] Fixing plates 6 are fixedly connected to both sides of the mounting plate 5. The fixing plates 6 have second fixing holes. The connecting plate 2 has a connecting groove 4 on the side away from the reinforcing plate 3. The mounting plate 5 and the fixing plates 6 are both inserted into the connecting groove 4.

[0031] The reinforcing plate 3 can strengthen the connecting plate 2, reduce the possibility of the connecting plate 2 breaking, and improve the service life of the connecting plate 2. At the same time, the setting of the first fixing hole and the second fixing hole makes it convenient for the staff to use bolts to fix the fixing plate 1 and the mounting plate 5, thus improving the stability of the device.

[0032] During assembly, the device first requires bolts to pass through the first fixing hole to fix the fixing plate 1 in the preset position. After the fixing plate 1 is installed, the mounting plate 5 needs to be installed on the connecting plate 2. When installing the connecting plate 2, the fixing piece 6 on the connecting plate 2 needs to be aligned with the connecting groove 4. Then, the mounting plate 5 and the fixing piece 6 are inserted into the connecting groove 4. Subsequently, bolts are used to pass through the second fixing hole to fix the mounting plate 5. After the mounting plate 5 is installed, the sliding contact line can be installed inside the sliding contact line mounting box 15. After the sliding contact line is installed, the sliding contact line mounting box 15 needs to be placed on the threaded rod 14. Then, the second nut 18 is rotated to reinforce the sliding contact line mounting box 15. After the sliding contact line mounting box 15 is fixed, the threaded rod 14 needs to pass through the mounting plate 5 and the second slider 12 in sequence. Then, the first nut 16 is rotated to tension the sliding contact line. When the first nut 16 compresses the second slider 12, the installation of the device is completed.

[0033] When the first nut 16 presses the second slider 12, the second slider 12 can slide on the threaded rod 14. When the second slider 12 slides, it can drive the first slider 10 to slide on the slide rod 8 through the connecting bar 11. When the first slider 10 slides, it will compress the spring 9. After the spring 9 is compressed, it will apply a reaction force to the first slider 10. This reaction force can be transmitted to the second slider 12 through the connecting bar 11, so that the second slider 12 can push the first nut 16. This setting can keep the sliding contact line in a taut state at all times, thus realizing the adaptive tensioning function of the device for the sliding contact line.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
