Description

Technical Field

[0001] This patent belongs to the field of railway passenger car energy device technology, and in particular relates to a pantograph device with adjustable working environment humidity for carbon sliding plates. Background Technology

[0002] The pantograph is one of the most widely used energy devices in railway passenger cars. Its working principle mainly relies on the cooperation of various linkage mechanisms to bring the carbon sliding plate of the pantograph head to a certain height, thereby achieving pantograph-catenary current collection contact and ensuring the stability of the train's power source. Currently, technological development in this field mainly focuses on improving the pantograph-catenary dynamic performance, enhancing the quality of pantograph-catenary current collection, and refining the pantograph's basic structure.

[0003] The existing technology has the following main drawbacks:

[0004] 1. The ambient humidity of the carbon contact plate has a serious impact on the friction state of the pantograph-catenary system. When the relative humidity of the air is too low, the carbon contact plate and the rigid contact wire are almost dry frictions, and it is not easy for an oxide film to form between them, which aggravates the wear of the carbon contact plate by the contact wire. The existing carbon contact plate of the pantograph device is fixed on the pantograph head mounting base and exposed to the air. The pantograph-catenary contact state under this structure is greatly affected by the air humidity, and it is impossible to adjust the friction state between the pantograph and the catenary in real time according to the ambient air humidity.

[0005] 2. After long-term use, the existing carbon sliding plate device has obvious indentation in the middle, but the carbon sliding plate material on both sides has not been effectively utilized, resulting in waste of carbon sliding plate material. The existing pantograph device cannot reasonably improve this phenomenon.

[0006] A search revealed Chinese invention patent application CN113212170A, which discloses a pantograph device with adjustable contact range. By designing a laterally extendable pantograph head and fixing it to the upper arm assembly, the pantograph head length can be controlled under different lateral wind speeds through the drive control of the upper arm assembly, thus avoiding problems such as pantograph penetration in strong crosswinds. Chinese utility model CN216861186U discloses a small lifting device for a high-speed rail pantograph. Through the design of the base and pantograph, the lifting mechanism is designed with multiple connecting blocks forming a multi-parallelogram structure. The base drive mechanism controls the raising and lowering of the pantograph head, improving the pantograph's operational stability. Summary of the Invention

[0007] The technical problem to be solved by this patent is to overcome the shortcomings of the prior art and provide a pantograph device with adjustable working environment humidity for the carbon pantograph, so as to ensure the constant humidity of the pantograph carbon pantograph under different environments, thereby improving the stability of current collection in different environments.

[0008] The technical solution adopted by this patent to solve its technical problem is: a pantograph device with adjustable working environment humidity for carbon slide plates, including a pantograph head, the pantograph head including a pantograph head bracket and a carbon slide plate, characterized in that: the pantograph head further includes a mounting base rotatably fixed to the pantograph head bracket, a carbon slide plate adjustment device disposed on the mounting base, and a slidable moisturizing chamber disposed on the pantograph head bracket, the carbon slide plate being disposed on the mounting base via the carbon slide plate adjustment device, the carbon slide plate adjustment device being used to adjust the carbon slide plate to a moisturizing position, and the moisturizing chamber being used to slide inward to allow the carbon slide plate to enter the moisturizing chamber for moisturizing operation.

[0009] Furthermore, the mounting base is provided with a pair of parallel and opposite sliding grooves. The carbon slide plate adjustment device includes a slider that is slidably disposed in the sliding groove and a rotating arm that is rotatably disposed at the top of the slider. The carbon slide plate is fixed across the rotating arm.

[0010] Furthermore, this pantograph device also has a carbon sliding plate rotating device for rotating the mounting base. The carbon sliding plate rotating device includes a telescopic cylinder, a telescopic rod, and a swing arm. The inner end of the telescopic cylinder is hinged to the middle of the pantograph head bracket. The telescopic rod is slidably engaged with the telescopic cylinder. The outer end of the telescopic rod is hinged to the movable end of the swing arm. The fixed end of the swing arm is fixed to the mounting base by a pin and rotatably connected to the pantograph head bracket.

[0011] In addition, the present invention also claims a method for moisturizing a carbon slide plate, characterized in that it is achieved by the aforementioned pantograph device, and the moisturizing method is as follows: first, the mounting base is rotated outward by 90° so that the carbon slide plate faces the middle of the pantograph head bracket; then, the carbon slide plate is adjusted to the moisturizing position by the carbon slide plate adjustment device; next, the moisturizing chamber slides inward so that the carbon slide plate enters the interior of the moisturizing chamber; finally, the carbon slide plate is moisturized by the moisturizing chamber.

[0012] Furthermore, the mounting base is driven to rotate by the carbon sliding plate rotating device. Specifically, the telescopic rod extends from the telescopic cylinder and pushes the movable end of the swing arm to rotate outward, and the mounting base moves in conjunction with the swing arm.

[0013] Furthermore, the working process of the carbon slide plate adjustment device is as follows: the slider slides out of the groove of the mounting base, and the rotating arm rotates downward at a certain angle so that the carbon slide plate reaches the opening position of the humidification chamber.

[0014] Compared to traditional pantograph structures, the beneficial effects of this patent include:

[0015] 1) Ensure the constant humidity of the pantograph carbon slide plate under different environments, thereby improving the stability of current collection in different environments;

[0016] 2) While ensuring the constant humidity effect of the carbon slide plate, the weathering effect of the carbon slide plate surface is improved, the plowing effect of the carbon slide plate surface is reduced, the wear of the pantograph is slowed down, and the service life of the carbon slide plate is increased.

[0017] 3) By cooperating with the bow head lifting mechanism, the bow head can move laterally at different heights, thereby improving the utilization rate of both sides of the carbon skateboard. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] like Figure 1 As shown, the pantograph device with adjustable working environment humidity for carbon sliding plates includes a pantograph head 1, a pantograph head lifting mechanism 2, and a base frame 3. The pantograph head 1 is connected to the pantograph head lifting mechanism 2 and the base frame 3. Figure 5As shown, a bow head lifting device 1-7 is fixed to the bottom of the middle part of the bow head bracket 1-2. The bow head lifting device 1-7 is connected to the bow head lifting mechanism 2 via a rotating joint, facilitating its cooperation with the bow head lifting mechanism 2 and enabling the pantograph head to complete the basic bow lifting operation. Based on the above structure, during the basic bow lifting process in this patent, the bow head lifting mechanism 2 gradually increases in vertical length and gradually decreases in horizontal width under the action of driving force, thereby driving the bow head assembly 1 to reach the specified height and realizing the friction current collection of the pantograph.

[0027] like Figure 2 , Figure 3 , Figure 4 As shown, the bow head 1 includes a bow head bracket 1-2, a carbon slide plate 1-1, a mounting base 1-4 rotatably fixed to the bow head bracket 1-2, a carbon slide plate rotating device 1-6 for rotating the mounting base 1-4, a carbon slide plate adjusting device 1-5 disposed on the mounting base 1-4, and a slidable moisturizing chamber 1-8 disposed on the bow head bracket 1-2. The moisturizing chamber 1-8 is used to slide inward to allow the carbon slide plate 1-1 to enter the interior of the moisturizing chamber 1-8 for moisturizing operations. The moisturizing chamber 1-8 is a box with an inward-facing opening, suitable for the carbon slide plate 1-1 to enter the interior of the box.

[0028] The carbon slide plate 1-1 is mounted on the mounting base 1-4 via a carbon slide plate adjustment device 1-5, which is used to adjust the carbon slide plate 1-1 to the moisture-retaining position. In this embodiment, the mounting base 1-4 is provided with a pair of parallel and opposite slide grooves. The carbon slide plate adjustment device 1-5 includes a slider 1-52 slidably disposed in the slide groove and a rotating arm 1-51 rotatably disposed at the top of the slider 1-52. The carbon slide plate 1-1 is fixed across the rotating arm 1-51. The carbon slide plate rotating device 1-6 includes a telescopic cylinder 1-63, a telescopic rod 1-62, and a swing arm 1-61. The inner end of the telescopic cylinder 1-63 is hinged to the middle of the bow head bracket 1-2. The telescopic rod 1-62 is slidably engaged with the telescopic cylinder 1-63. The outer end of the telescopic rod 1-62 is hinged to the movable end of the swing arm 1-61. The fixed end of the swing arm 1-61 is fixed to the mounting base 1-4 via a pin and rotatably connected to the bow head bracket 1-2.

[0029] The method for achieving carbon plate moisture retention using the pantograph device in this embodiment is as follows:

[0030] Step 1: Rotate the mounting base 1-4 outward by 90° so that the carbon slide plate 1-1 faces the middle of the bow head bracket 1-2. Specifically, in this step, the mounting base 1-4 is driven to rotate by the carbon slide plate rotating device 1-6. Specifically, the telescopic rod 1-62 extends from the telescopic cylinder 1-63 and pushes the movable end of the swing arm 1-61 to rotate outward. The mounting base 1-4 moves in conjunction with the swing arm (1-61).

[0031] Step 2: Adjust the carbon slide plate 1-1 to the humidification position using the carbon slide plate adjustment device 1-5. The working process of the carbon slide plate adjustment device 1-5 is as follows: the slider 1-52 slides out from the groove of the mounting base 1-4, and the rotating arm 1-51 rotates downward at a certain angle so that the carbon slide plate 1-1 reaches the opening position of the humidification chamber 1-8.

[0032] Step 3: Slide the humidification chamber 1-8 inward to allow the carbon slide plate 1-1 to enter the humidification chamber 1-8;

[0033] Step 4: Moisturize the carbon slide plate 1-1 through the moisturizing chamber 1-8;

[0034] Step 5: After the moisturizing operation is completed, the above operation is performed in reverse so that the carbon slide plate 1-1 can re-enter the flow receiving working state.

[0035] In addition, to ensure that the pantograph receives current normally during train operation, the two carbon sliding plates 1-1 will sequentially perform the above-mentioned moisturizing operation procedure. While ensuring that one carbon sliding plate 1-1 is moisturized, the other carbon sliding plate 1-1 can be in a normal current receiving state, so as to ensure the continuity of the train's power source and ensure the stability and safety of train operation.

[0036] Based on the above structure, during train operation, the pantograph lifting mechanism 2 will drive the pantograph head to move laterally along the direction of the car body in real time according to the pantograph-catenary contact situation, and adjust the position of the pantograph-catenary contact point in real time. In conjunction with the "Z"-shaped catenary arrangement, it ensures the uniformity of the overall force on the carbon sliding plate 1-1, further avoids the generation of local pits in the carbon sliding plate 1-1, and improves its overall utilization rate.

[0037] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
