Description

Technical Field

[0001] This invention belongs to the field of new energy locomotive technology, specifically relating to an electric-electric dual-power new energy locomotive. Background Technology

[0002] The electric-electric dual-power new energy locomotive is a hybrid locomotive independently developed in my country. It adopts a dual power supply method, using both overhead contact lines and power batteries, to propel the locomotive along a predetermined track for transporting goods. Above the track on which the electric-electric dual-power new energy locomotive travels, there is an overhead contact line consisting of power transmission lines. During the locomotive's movement, the pantograph installed on the top of the locomotive comes into contact with the lines in the overhead contact line. Using the pantograph, the power from the overhead contact line is input into the electric-electric dual-power new energy locomotive for its operation.

[0003] Chinese invention patent publication number CN112172529A discloses a pantograph head, a pantograph, and a control method for the pantograph. The pantograph head includes a support structure and a contact structure. The support structure consists of a first sliding plate bracket group, a second sliding plate bracket group, and multiple sliding plate supports. The first and second sliding plate bracket groups are arranged opposite to each other, and the sliding plate supports are connected to the first and second sliding plate bracket groups. The contact structure mainly consists of a telescopic structure that adjusts the length of the pantograph head. The aforementioned pantograph head can flexibly adjust its length according to the spacing of the overhead contact line installed on the railway, expanding the applicability of the pantograph head. However, there are certain problems in actual use. Specifically, although the pantograph head can adjust its spacing, when the pantograph head comes into contact with the line in the overhead contact line of the predetermined specification, the contact position between the line and the pantograph head does not change directly. This results in severe wear on the contact part between the pantograph head and the line, while other parts of the pantograph head do not suffer excessive wear, affecting the overall service life of the pantograph head and reducing its quality of use.

The arc-shaped contact groove is bonded to the side wall of the circuit in a point contact manner.

[0011] As a preferred embodiment of the present invention, the bonding assembly includes a mounting base, a top block, and a contact block. The top block is mounted on the upper surface of the end of the mating bracket, and a fixing base is mounted on one side of the top block. The fixing base is connected to the end of the mating bracket by a screw. The contact block is mounted on the other side of the top block. An arc-shaped contact groove is formed on the side wall of the contact block. The radius of the arc-shaped contact groove is the same as the radius of the line. The arc-shaped contact groove is bonded to the side wall of the line in a surface contact manner. The arc-shaped contact groove further increases the contact area between the pantograph frame and the line.

[0012] As a preferred embodiment of the present invention, the pantograph support mainly consists of an angle adjustment component and a control component. The angle adjustment component adjusts the height of the pantograph frame, and the control component controls the horizontal angle of the pantograph frame.

[0013] As a preferred embodiment of the present invention, the angle adjustment assembly includes a bottom bracket, a fixed frame, and a support arm. The bottom bracket is installed on the upper surface of the new energy vehicle body, the fixed frame is installed on the bottom bracket, and the support arm is installed between the fixed frame and the pantograph arm. A telescopic cylinder is installed between the end of the pantograph arm and the side wall of the bottom bracket. The extension and retraction of the output end of the telescopic cylinder drives the pantograph arm to rotate about the end of the support arm as the axis.

[0014] As a preferred embodiment of the present invention, the control component includes an adjusting cylinder, which is installed between the moving mechanism and the support arm. The extension and retraction of the output end of the adjusting cylinder adjusts the horizontal angle of the pantograph frame, so that the pantograph frame fits against the bottom end of the line at an angle horizontal to the line.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The moving mechanism and the cooperating mechanism in this invention enable horizontal movement of the pantograph body as the main body of the new energy locomotive moves along the track, continuously changing the contact area between the line and the pantograph body. This allows the upper surface of the pantograph body to evenly receive friction from the line, preventing severe wear in a single area of ​​the pantograph body that could limit its overall service life. Furthermore, the cooperating mechanism allows the cleaning component to remove dust, particles, and other impurities adhering to the surface of the pantograph body during its movement, preventing these impurities from affecting its conductivity. The bonding component limits the maximum swing range of the line, and when the line's initial position is on the sidewall of the bonding component, it can further... To increase the overall conductive area and allow more stable power to enter the main body of the new energy locomotive, providing power for its operation, the bonding component of this invention includes a top plate, a bonding block, and a mounting base. The side wall of the bonding block is bonded to the side wall of the line.

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments. The present invention provides the following embodiments.

[0031] Example 1

[0032] like Figure 1 and Figure 2As shown, this is a structural schematic diagram of the electric-electric dual-power new energy locomotive in this embodiment. The electric-electric dual-power new energy locomotive in this embodiment can closely fit the lines in the contact network and changes the contact points with the lines in the contact network to prevent severe wear on a certain part of the pantograph head. The electric-electric dual-power new energy locomotive includes a new energy locomotive body 1 and a pantograph bracket 2 installed on the new energy locomotive body 1. A power battery is installed inside the new energy locomotive body 1 for power supply. The new energy locomotive body 1 moves along a preset track. The system is equipped with an overhead contact line. A pantograph arm 3 is mounted on the pantograph bracket 2, and a pantograph frame 4 is mounted at the end of the pantograph arm 3. The pantograph frame 4 is in contact with the line in the contact line to guide and receive the power in the line. The pantograph bracket 2 can adjust and control the position and angle of the pantograph arm 3 and the pantograph frame 4 to enhance the stability of the pantograph frame 4 in contact with the line and ensure that the power in the contact line passes stably through the pantograph frame 4 and is received by the new energy locomotive body 1. A flexible moving mechanism 5 is installed below the pantograph frame 4 to adjust the contact position between the pantograph frame 4 and the line.

[0033] As attached Figure 3 As shown, this is a structural schematic diagram of the pantograph support 2 in this embodiment. The pantograph support 2 includes a bottom support 21, a fixed frame 22, a support arm 23, and a telescopic cylinder 24. The bottom support 21 is installed on the upper surface of the new energy vehicle body 1, and the fixed frame 22 is installed on the bottom support 21. The support arm 23 is provided between the fixed frame 22 and the pantograph arm 3. The support arm 23 serves as a support point for the angular rotation of the pantograph arm 3, and its overall position and angle are fixed. The telescopic cylinder 24 is installed at the end of the bottom support 21. The end of the telescopic cylinder 24 is rotatably connected to the end of the pantograph arm 3. As the length of the telescopic cylinder 24 increases... As the pantograph arm 3 contracts, it rotates around the end of the support arm 23 as the axis, adjusting the overall tilt of the pantograph arm 3 and adjusting the horizontal height of the pantograph frame 4 at the end of the pantograph arm 3. An adjusting cylinder 25 is installed on the side of the support arm 23, and the other end of the adjusting cylinder 25 is connected to the bottom of the moving mechanism 5. As the length of the adjusting cylinder 25 changes, the angle of the pantograph frame 4 itself is adjusted, so that the pantograph frame 4 remains horizontal with the line and fits with the line, ensuring that the power of the line in the contact network can stably pass through the pantograph frame 4 to supply the new energy locomotive body 1.

[0034] It is worth noting that in this embodiment, the bottom bracket 21, the fixing frame 22, the support arm 23 and the telescopic cylinder 24 form the angle adjustment component of the pantograph arm 3, and the adjustment cylinder 25 is the control component for the horizontal angle of the pantograph frame 4.

[0035] As attached Figure 5As shown, it is a structural schematic diagram of the pantograph frame 4 in this embodiment. The pantograph frame 4 is mainly composed of a pantograph body 41, a fitting part 42 and an arc-shaped part 43. The pantograph body 41 is mounted on the moving mechanism 5. The fitting part 42 is installed on the upper surface of the pantograph body 41 to fit with the line and receive the power in the line. Arc-shaped parts 43 are installed at both ends of the pantograph body 41.

[0036] It is worth noting that the pantograph frame 4 is made of carbon-based or copper-based composite materials, which have high conductivity and self-lubricating properties, reducing friction and wear, and ensuring the conductivity of the pantograph frame 4 itself.

[0037] As attached Figure 4 The diagram shows the structure of the moving mechanism 5 in this embodiment. The moving mechanism 5 includes a lower housing 51, a lead screw 52, ​​and a guide rod 53. The lower housing 51 is installed at the end of the pantograph arm 3 and is connected to the end of the adjusting cylinder 25. A moving groove is provided inside the lower housing 51, and the lead screw 52 is rotatably installed in the moving groove. A moving end 54 is threaded onto the outside of the lead screw 52 and is connected to the bottom end of the pantograph frame 4. A drive motor is installed inside the lower housing 51, and the output end of the drive motor is connected to the end of the lead screw 52. As the drive motor rotates, the lead screw 52 rotates in the moving groove. At this time, the moving end 54 moves along the length of the lead screw 52, ​​controlling the overall position of the pantograph frame 4 and allowing the pantograph to move. The pantograph 4 moves to one side, and the rotation direction of the lead screw 52 is controlled by switching the current direction of the drive motor, thereby controlling the movement direction of the pantograph 4 and realizing the purpose of the pantograph 4 reciprocating on the lower housing 51. At this time, the pantograph 4 maintains a horizontal state and sways left and right, constantly changing the contact point between the pantograph 4 and the line, avoiding excessive wear on a certain part of the pantograph 4, which would affect the overall service life. In addition, a guide rod 53 is installed in the moving groove. The guide rod 53 is horizontal with the lead screw 52 and is slidably connected to the moving end 54. The establishment of the guide rod 53 limits the movement trajectory of the moving end 54 and ensures the stability of the moving end 54 during movement.

[0038] As attached Figure 6 and Figure 7As shown, this is a schematic diagram of the mating mechanism 6 in this embodiment. The mating mechanism 6 includes symmetrically mounted mating mechanisms 6 on both sides of the lower housing 51 to limit the movement range of the line. The mating mechanism 6 includes a mounting bracket 61, a mating bracket 62, and a bonding component 63. The mounting bracket 61 is symmetrically mounted on both sides of the lower housing 51, and the mating bracket 62 is mounted on the mounting bracket 61. A cleaning component 64 is mounted on the lower surface of the end of the mating bracket 62. The cleaning component 64 is a cleaning brush for cleaning dust and particles from the surface of the pantograph frame 4. When the pantograph frame 4 sways left and right under the movement of the moving mechanism 5, the cleaning brush can stably clean the impurities attached to the surface of the pantograph frame 4, ensuring the cleanliness of the pantograph frame 4 surface and preventing a large amount of impurities from adhering to the surface of the pantograph frame 4 due to dust stirred up by strong winds, which would otherwise damage the pantograph. The conductivity of the pantograph frame 4 itself has a direct impact, and a conductive slider 65 is installed on the side wall of the mounting bracket 61. The conductive slider 65 is in contact with the side wall of the pantograph frame 4 and slides along the side wall of the pantograph frame 4. A bonding component 63 is installed on the upper surface of the end of the cooperating bracket 62. The bonding component 63 is in contact with the side wall of the line, limiting the position of the line and ensuring that the line is always in contact with the upper surface of the pantograph frame 4. It is worth noting that the bonding component 63, cooperating bracket 62, mounting bracket 61 and conductive slider 65 in this embodiment are made of the same materials and have the same properties as the pantograph frame 4. The power received by the side wall of the bonding component 63 passes through the mounting bracket 61, cooperating bracket 62 and conductive slider 65 and also enters the pantograph frame 4, increasing the overall contact area between the pantograph and the line and ensuring the conductivity stability of the pantograph frame 4.

[0039] It is worth noting that when the initial position of the line is between multiple sets of bonding components 63, the bonding components 63 limit the position of the line. When the main body 1 of the new energy locomotive turns along the track, the line will deflect to one side due to the curvature of the line and the track itself. At this time, the bonding components 63 will block and limit the position of the line, allowing the line to move within a predetermined range. By using the movement of the line itself, the contact surface between the line and the pantograph frame 4 is further adjusted, ensuring the effectiveness of the pantograph frame 4.

[0040] As attached Figure 8As shown, this is a schematic diagram of the bonding component 63 in this embodiment. The bonding component 63 includes a top plate 631, a bonding block 632, and a mounting base 633. The top plate 631 is provided on the upper surface of the end of the bracket 62. The mounting base 633 is installed on one side of the top plate 631 and is fixed to the bracket 62 by a screw. The bonding block 632 is installed on the other side of the top plate 631. The bonding block 632 is bonded to the side wall of the line. The bonding block 632 is bonded to the side wall of the line in a point contact manner. By utilizing the material characteristics of the bonding component 63 as a whole, the overall conductivity of the pantograph frame 4 is further enhanced.

[0041] Example 2

[0042] As attached Figure 9 and Figure 10 As shown, this is a schematic diagram of the bonding component 63 in this embodiment. The difference between this embodiment and Embodiment 1 is that the bonding component 63 includes a top block 634, a contact block 635, and a fixing seat 636. The top block 634 is provided on the upper surface of the end of the bracket 62. The fixing seat 636 is installed on one side of the top block 634, and the contact block 635 is installed on the other side of the top block 634. An arc-shaped contact groove is provided on the side wall of the contact block 635. The contact block 635 is bonded to the side wall of the circuit in a point contact manner. When the radius of the circuit is the same as the radius of the arc-shaped contact groove, the contact block 635 is bonded to the side wall of the circuit in a surface contact manner, which further increases the contact area between the contact block 635 and the circuit and improves its conductivity.

[0043] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present invention, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted herein.
