Description

Technical Field

[0001] The utility model belongs to the technical field of catenary maintenance and relates to a pantograph cable de-icing device. Background Art

[0002] In recent years, the rail transit in China has developed rapidly. The normal operation of rail transit such as high-speed railways and light rails depends on the catenary that provides power. The catenary includes a pantograph cable. In the north, as well as in Yunnan and Guizhou regions, the pantograph cable has the problem of icing, which leads to poor contact of the rail transit and reduces the driving safety. Therefore, it is necessary to remove the ice on the pantograph cable.

[0003] The existing devices for removing ice on the pantograph cable, for example, a Chinese patent document discloses a rapid removal device for foreign objects on a railway catenary [Patent No.: 202122840957.5; Publication No.: CN216215460U]. It includes a de-icing mechanism, a rail car, and a lift. The de-icing mechanism is connected to the rail car through the lift. The de-icing mechanism includes a first knocking rod, a second knocking rod, and a mounting seat. The middle of the first knocking rod and the second knocking rod are rotatably installed on the left side of the mounting seat. A tension spring is fixedly connected between the bottoms of the first knocking rod and the second knocking rod. A cam is rotatably installed on the left side of the mounting seat. An ice removal motor for driving the cam is arranged inside the mounting seat. The surfaces of the cam are respectively lapped with the surfaces of the first knocking rod and the second knocking rod.

[0004] For the removal device with such a structure, the ice removal motor drives the cam to rotate and cooperate with the tension spring to drive the first knocking rod and the second knocking rod to swing repeatedly, so as to knock the ice on the pantograph cable and make the ice break and fall off. However, in the actual environment, the pantograph cable is not a straight line but winding. Both the first knocking rod and the second knocking rod are rigid rods. For the removal device with such a structure, there is a problem that the first knocking rod cannot knock on the pantograph cable, and after the second knocking rod contacts the pantograph cable, it needs to push the pantograph cable. Moreover, the pantograph cable is relatively heavy, resulting in that the removal device with such a structure cannot clean the ice well, the de-icing effect is poor, and because the second knocking rod cannot push the pantograph cable, the ice removal motor is burned out, leading to easy damage of the removal device. Summary of the Invention

[0005] The purpose of the utility model is to propose a pantograph cable de-icing device for the above problems existing in the prior art, and the technical problem to be solved is how to ensure the de-icing effect of the de-icing device while making the de-icing device not easily damaged.

[0006] The object of the present utility model can be achieved by the following technical solutions: A catenary de-icing device, comprising a chassis, a moving structure provided at the bottom of the chassis, a lifting structure provided at the top of the chassis, and a first driver provided at the top of the lifting structure. It is characterized in that a plurality of elastic hammers arranged at intervals are fixedly connected to the output shaft of the first driver, the outer ends of the elastic hammers can touch the catenary, and a plurality of guide wheels capable of moving along the catenary are provided on the first driver.

[0007] During operation, the first driver, the elastic hammers and the guide wheels are located at an appropriate height through the lifting structure. The first driver drives the elastic hammers to rotate, so that the elastic hammers strike the ice coating, break the ice coating, and make the ice coating fall off. Moreover, the elastic hammers are elastic. When striking the ice coating, the elastic hammers will produce a certain deformation and cross over the ice coating and the catenary, which is a flexible contact, and will not damage the elastic hammers, nor will it burn out the first driver due to jamming. While ensuring the de-icing effect of the de-icing device, the de-icing device is not easily damaged. The de-icing device moves along the track through the moving structure, and the guide wheels move along the catenary, ensuring that the elastic hammers are always close to the catenary, ensuring that the elastic hammers can strike the ice coating, and improving the de-icing effect of the de-icing device.

[0008] In the above-mentioned catenary de-icing device, the elastic hammer includes a fixed column fixed on the output shaft of the first driver, a spring, and an elastic column made of rubber material. The inner end of the spring is fixedly connected to the fixed column, and the outer end is fixedly connected to the elastic column. The elastic column can touch the catenary. The setting of the spring enables the elastic column to bend, enabling the elastic column to rotate across the ice coating and the catenary, without the problem of jamming. At the same time, the elastic column has sufficient striking force. The elastic column is made of rubber material, and when the elastic column strikes, it has sufficient crushing effect and will not damage the catenary.

[0009] In the above-mentioned catenary de-icing device, a guide groove recessed in a circular shape is provided on the outer peripheral wall of the guide wheel, and a part of the catenary is embedded in the guide groove. This structure enables the guide wheel to move better along the catenary, enabling the elastic hammer to break the ice coating better.

[0010] In the above-mentioned catenary de-icing device, a following bracket is provided at the top of the lifting structure. A second driver is hinged on the following bracket. A plurality of first hinge rods are provided between the following bracket and the first driver. One end of the first hinge rod is hinged to the following bracket, and the other end is hinged to the first driver. All the first hinge rods are parallel, and the second driver is hinged to one of the first hinge rods. This structure can finely adjust the height of the first driver through the second driver, ensure that the guide wheels move along the catenary, ensure that the elastic hammers can break the ice coating, and ensure the de-icing effect of the de-icing device while making the de-icing device not easily damaged.

[0011] In the above-mentioned ice removal device for catenary, the following support includes a plurality of parallel sliding rods and a sliding plate slidably disposed on the sliding rods. The sliding rods are perpendicular to the output shaft of the first driver, and both the second driver and the first articulated rod are articulated to the sliding plate. With this structure, the first driver can translate left and right along the track, which can better cooperate with the curved catenary, keep the first driver always directly below the catenary, and ensure that the elastic hammer can always strike the ice coating, guaranteeing the ice removal effect of the ice removal device while making the ice removal device not easily damaged.

[0012] In the above-mentioned ice removal device for catenary, a plurality of sets of rotating brushes spaced apart are also fixedly connected to the output shaft of the first driver. The outer ends of the rotating brushes can touch the catenary, and the elastic hammers and the rotating brushes are alternately spaced along the axial direction of the output shaft of the first driver. With this structure, the ice coating is broken by the elastic hammers, and the residual ice on the catenary is cleaned by the rotating brushes, ensuring that the ice coating on the catenary is cleaned thoroughly; the outer ends of the rotating brushes are brush hairs, which can be bent and deformed and can cross the catenary after contacting it.

[0013] As another case, in the above-mentioned ice removal device for catenary, a plurality of sets of rotating brushes spaced apart are also fixedly connected to the output shaft of the first driver. The outer ends of the rotating brushes can touch the catenary, all the elastic hammers are located at the outer end of the output shaft of the first driver, and all the rotating brushes are located between the elastic hammers and the housing of the first driver.

[0014] In the above-mentioned ice removal device for catenary, the moving structure includes land wheels disposed on both sides of the bottom of the chassis, a third driver disposed in the chassis, second articulated rods hinged to the front and rear ends of the bottom of the chassis, and track wheels disposed at the bottom of the second articulated rods. The output shaft of the third driver is articulated to the top of the second articulated rod, and the third driver can drive the second articulated rod to rotate so that the track wheels are located above or below the land wheels. When the track wheels are located above the land wheels, the ice removal device can move on flat ground through the land wheels; when the track wheels are located below the land wheels, the ice removal device can move on the track through the track wheels.

[0015] As another case, in the above-mentioned overhead contact line de-icing device, the moving structure includes land wheels arranged on both sides of the bottom of the chassis, a third driver arranged in the chassis, and track wheels arranged on the output shaft of the third driver. The third driver can drive the track wheels to be located above or below the land wheels. When the track wheels are located above the land wheels, the de-icing device can walk on flat ground through the land wheels. When the track wheels are located below the land wheels, the de-icing device can walk on the track through the track wheels.

[0016] In the above-mentioned overhead contact line de-icing device, a hot air blower is provided on the first driver. The air outlet of the hot air blower faces the overhead contact line, and the hot air blower is located within the area surrounded by the guide wheels. By blowing hot air onto the overhead contact line with the hot air blower, the residual ice on the overhead contact line can be melted, ensuring the de-icing effect of the de-icing device.

[0017] Compared with the prior art, the overhead contact line de-icing device provided by the present utility model has the following advantages:

[0018] 1. The elastic hammer of this de-icing device knocks the ice coating flexibly, which will not damage the elastic hammer nor burn out the first driver due to jamming, making the de-icing device not easily damaged while ensuring the de-icing effect of the de-icing device.

[0019] 2. This de-icing device moves along the overhead contact line through the guide wheels, and the first driver can translate in the left-right direction of the track, which can better cooperate with the curved overhead contact line, keep the first driver always directly below the overhead contact line, and enable the elastic hammer to always knock the ice coating, making the de-icing device not easily damaged while ensuring the de-icing effect of the de-icing device.
