Description

Technical Field

[0001] This utility model relates to the field of pantograph technology, specifically to an intelligent pantograph adjustment device. Background Technology

[0002] A pantograph is an electrical device installed on the top of rail transit vehicles such as electric locomotives and EMUs. It receives electrical energy by contacting the overhead contact line to power the vehicle.

[0003] Existing pantograph intelligent adjustment devices rely on the elasticity of springs to push the pantograph arm during use. However, strong winds during vehicle movement can push the pantograph arm, causing the spring to compress. This compression can prevent the pantograph arm from connecting with the top connection line. Furthermore, the graphite plate needs to be replaced after prolonged use, and the replacement method is extremely cumbersome. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an intelligent pantograph adjustment device, which has the advantages of spring force adjustment and easy replacement of graphite plates, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a pantograph intelligent adjustment device, including a base, a first connecting rod rotatably connected to the top of the base, a second connecting rod rotatably connected to the top of the first connecting rod, a pantograph wall rotatably connected to the top of the second connecting rod, a motor fixedly installed on the outer wall of the base, a sliding groove fixedly installed on the top of the base, a sliding frame slidably connected to the top of the sliding groove, a spring seat fixedly installed on the outer wall of the sliding frame, a thrust spring fixedly installed on the outer wall of the spring seat, a threaded rod fixedly installed on the output shaft of the motor, a limit rod fixedly installed on the inner wall of the base, a fixed shell fixedly installed on the outer wall of the pantograph wall, a graphite plate provided on the top of the fixed shell, an mounting plate fixedly installed on the bottom of the graphite plate, an insert block slidably connected to the inner wall of the fixed shell, a threaded column rotatably connected to the outer wall of the insert block, a slot provided on the outer wall of the mounting plate, and a rotating head fixedly installed on the outer wall of the threaded column.

[0006] As a preferred technical solution of this utility model: the threaded column penetrates the fixed shell, and the threaded column and the fixed shell are connected by threads.

[0007] As a preferred technical solution of this utility model: the side of the insert block near the slot has the same shape as the slot, and the side of the insert block away from the slot is in contact with the inner wall of the fixing shell.

[0008] As a preferred technical solution of this utility model: there are two limiting rods, and the two limiting rods are symmetrically arranged. The two limiting rods pass through the sliding frame, and the sliding frame is slidably connected to the limiting rods.

[0009] As a preferred technical solution of this utility model: the threaded rod passes through the sliding frame, and the threaded rod and the sliding frame are connected by a thread.

[0010] As a preferred technical solution of this utility model: the bottom of the sliding frame is adapted to the inner wall of the sliding groove, and the bottom of the sliding frame is located on the inner wall of the sliding groove.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. When the train is traveling at a high speed, the wind force received by the device increases. At this time, the motor is started, which drives the threaded rod to rotate. The threaded rod moves the sliding frame through the threaded connection with the sliding frame. The sliding frame moves the spring seat, which in turn moves one end of the thrust spring. This adjusts the position of the end of the thrust spring away from the first link, thereby adjusting the elasticity of the thrust spring on the first link.

[0013] 2. The pantograph intelligent adjustment device rotates the rotating head, causing the threaded column to rotate. This causes the threaded column to move along the inner wall of the fixed shell through its threaded connection with the fixed shell. Consequently, the threaded column moves the insert block, causing it to disengage from the slot. At this point, the fixing relationship of the mounting plate disappears, and the graphite plate is pulled upward, causing it to pull the mounting plate out of the fixed shell for replacement.

[0020] 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.

[0021] Please see Figure 1 - Figure 5 The pantograph intelligent adjustment device includes a base 1, a first connecting rod 2 rotatably connected to the top of the base 1, a second connecting rod 3 rotatably connected to the top of the first connecting rod 2, a pantograph wall 11 rotatably connected to the top of the second connecting rod 3, a motor 5 fixedly installed on the outer wall of the base 1, a slide groove 4 fixedly installed on the top of the base 1, a sliding frame 6 slidably connected to the top of the slide groove 4, a spring seat 7 fixedly installed on the outer wall of the sliding frame 6, a thrust spring 8 fixedly installed on the outer wall of the spring seat 7, a threaded rod 9 fixedly installed on the output shaft of the motor 5, a limit rod 10 fixedly installed on the inner wall of the base 1, a fixed shell 12 fixedly installed on the outer wall of the pantograph wall 11, a graphite plate 13 provided on the top of the fixed shell 12, an installation plate 14 fixedly installed on the bottom of the graphite plate 13, an insert block 17 slidably connected to the inner wall of the fixed shell 12, a threaded column 15 rotatably connected to the outer wall of the insert block 17, a slot 18 opened on the outer wall of the installation plate 14, and a rotating head 16 fixedly installed on the outer wall of the threaded column 15.

[0022] In the above structure, the mounting plate 14 is adapted to the inner wall of the fixed shell 12, so that the mounting plate 14 is aligned with the inner wall of the fixed shell 12 and the mounting plate 14 is pushed down, so that the mounting plate 14 enters the inner wall of the fixed shell 12, thereby forming a connection between the mounting plate 14 and the fixed shell 12.

[0023] In a preferred embodiment: the threaded post 15 penetrates the fixed shell 12, and the threaded post 15 and the fixed shell 12 are threadedly connected.

[0024] In the above structure, by rotating the rotating head 16, the rotating head 16 drives the threaded column 15 to rotate, so that the threaded column 15 moves on the inner wall of the fixed shell 12 through the threaded connection with the fixed shell 12, thereby causing the threaded column 15 to drive the insert block 17 to move.

[0025] In a preferred embodiment: the side of the insert 17 closest to the slot 18 has the same shape as the slot 18, and the side of the insert 17 furthest from the slot 18 is in contact with the inner wall of the fixing shell 12;

[0026] In the above structure, the insertion block 17 is adapted to the inner wall of the slot 18, so that after the insertion block 17 enters the interior of the slot 18, the insertion block 17 fixes the position of the slot 18, thereby fixing the position of the graphite plate 13. At the same time, the slot 18 fits against the inner wall of the fixing shell 12, so that the slot 18 will not tilt when it moves.

[0027] In a preferred embodiment: there are two limiting rods 10, and the two limiting rods 10 are symmetrically arranged. The two limiting rods 10 pass through the sliding frame 6, and the sliding frame 6 is slidably connected to the limiting rods 10.

[0028] In the above structure, the two sides of the sliding frame 6 are limited by two limiting rods 10, so that the sliding frame 6 can only slide on the outer wall of the two limiting rods 10 when it moves, thus preventing the sliding frame 6 from tilting when it moves.

[0029] In a preferred embodiment: the threaded rod 9 passes through the sliding frame 6, and the threaded rod 9 and the sliding frame 6 are threadedly connected;

[0030] In the above structure, by starting the motor 5, the motor 5 drives the threaded rod 9 to rotate, and the threaded rod 9 drives the sliding frame 6 to move through the threaded connection with the sliding frame 6, which in turn drives the spring seat 7 to move.

[0031] In a preferred embodiment: the bottom of the sliding frame 6 is adapted to the inner wall of the slide groove 4, and the bottom of the sliding frame 6 is located on the inner wall of the slide groove 4;

[0032] In the above structure, when the sliding frame 6 moves, since its bottom is located in the inner wall of the sliding groove 4, the sliding groove 4 supports the bottom of the sliding frame 6, so that the sliding frame 6 will not move up and down when it moves.

[0033] Working principle: When the equipment is in use, the graphite plate 13 connects to the top wiring, and then the power is transmitted to the vehicle through the first connecting rod 2. At higher vehicle speeds, the equipment is affected by wind speed. Starting the motor 5 causes the threaded rod 9 to rotate, which in turn moves the sliding frame 6 via its threaded connection. This, in turn, moves the spring seat 7, which in turn moves one end of the thrust spring 8. This adjusts the position of the end of the thrust spring 8 furthest from the first connecting rod 2, thus adjusting the position of the first connecting rod. The elasticity of the thrust spring 8 on the connecting rod 2 is adjusted. When the graphite plate 13 needs to be replaced, the rotating head 16 is rotated, causing the threaded column 15 to rotate. This causes the threaded column 15 to move through the threaded connection with the fixed shell 12 to the inner wall of the fixed shell 12. This causes the threaded column 15 to move the insert block 17, causing the insert block 17 to disengage from the slot 18. At this time, the fixing relationship of the mounting plate 14 is lost, and the graphite plate 13 is pulled upward, causing the graphite plate 13 to pull the mounting plate 14 out of the fixed shell 12 for replacement.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
