Pantograph protection device for rail traffic

Abstract

The invention relates to the technical field of rail traffic equipment, and discloses a pantograph protection device for rail traffic. The pantograph protection device comprises an upper pantograph frame; a sliding plate is arranged on one side of the top end of the upper pantograph frame; the top end of the sliding plate is movably connected with a pneumatic connecting rod which is arranged in the middle of the top end of the upper pantograph frame; a supporting frame is fixedly mounted at the top end of the pneumatic connecting rod; and a fixing frame is fixedly mounted on one side of the top end of the supporting frame. According to the pantograph protection device for rail traffic, through arrangement of adjusting clamping sleeves and clearing balls, a contact net is under half cladding of the clearing balls, thus the adjusting clamping sleeves in high-speed movement drive the clearing balls in the inner walls of the adjusting clamping sleeves to rotate at a high speed under the friction effect of the relatively-static contact net, then hard burrs or contaminants on the surface of the contact net are polished and cleared, abrasion of the sliding plate in high-speed movement islowered, and the service life of the sliding plate is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of rail transit equipment, in particular to a pantograph protection device for rail transit. Background technique [0002] Pantograph such as figure 1 As shown, it is the electrical equipment installed on the roof of the motor car to obtain electric energy from the catenary. The quality of the condition can directly affect the safety of the moving train, so ensuring the good working condition of the pantograph is an important factor to maintain the stable and safe movement of the moving train. However, there are many hard burrs on the surface of the newly constructed catenary. The hard burrs will generate greater frictional resistance to the sliding plate, which intensifies the physical wear of the sliding plate on the pantograph, and because the catenary has been exposed outdoors, the surface of the catenary is easily polluted by bird droppings or other substances. At the same time, in the cold winter, th...

Problems solved by technology

[0004] The invention provides a pantograph protection device for rail transit, which can quickly polish the hard burrs on the catenary, effectively remove pollutants such as bird droppings or ice on the catenary, and avoid intermittent energization. The advantage of causing damage to the electronic components inside the motor car solves the problem that the existing pantograph cleaning protection device often uses a scraper to clean the pollutants on the catenary, but when the motor car is running at high speed, the newly built The burrs on the catenary and the pollutants on the catenary will have a severe impact on the scraper, which may easily cause the scraper to break and damage, so that the pollutants on the catenary cannot be effectively cleaned, and the device cannot be protected. At the same time, the cracked gap of the scraper is relatively sharp, and it is easy to cause scratch damage to the catenary during its high-speed movement, which seriously reduces the service life of the catenary, and the catenary has a large temperature difference or a large area span. When it is large, the catenary will fall in a different degree of arc, and the skateboard in contact with the highest point of the bottom of the catenary will squeeze and swing left and right under the high-speed motion of the pantograph, or the skateboard will fall when the train is turning. There will also be relatively violent shaking between the skateboard and the catenary, which will lead to offline and poor contact between the skateboard and the catenary in high-speed motion, which will lead to intermittent electrical connection between the skateboard and the catenary. The situation makes the bullet trains have major safety hazards in high-speed driving
