In the third rail power supply mode, the current receiving device is used for contacting with the third rail to smoothly slide and take current, so that the third rail DC1500V is connected to the vehicle to supply power. The collector shoe of the current collector comprises: the current collector mainly comprises a mounting plate, a back plate, a cylinder, a crank connecting rod mechanism, a spring device, an elastic bearing, a connecting plate, a current collecting arm (comprising an insulating swing rod, a supporting shoe and a current collecting carbon sliding plate) and other parts.
For the maintenance means of the collector shoe, in daily inspection and maintenance, except for inspecting the appearance of the collector shoe to be normal, parts to be free of loss, inspecting each fixing bolt to be free of looseness, clear scribing, breakage-free hose, fastening and leakage-free joint positions and fastening connector plug installation, important two steps also need to measure parameters of the distance between the upper surface of the carbon sliding plate and the rail top of the collector shoe carbon sliding plate in two states of shoe lifting and shoe lifting, and the specified parameter index is the allowable range of the shoe lifting: 142 +/-3 mm; boot allowance range: 260 (+ 0, — 15) mm; arm shaft allowable range: 193. + -. 2 mm. And when the collector shoe is jointed with the third rail (the highest position of the carbon sliding plate of the collector shoe is 200mm away from the top surface of the rail), the elastic parameter in the axial direction of the arm has a specified parameter index of 130N +/-15N of contact force. The height of the upper surface of the carbon sliding plate of the collector shoe from the rail top in the two states of the collector shoe and the collector shoe is an important index for measuring whether the collector shoe can be invaded by the limit and whether the collector shoe can be smoothly and smoothly connected into a third rail in a grid rail conversion area; when the highest position of the collector shoe carbon sliding plate is 200mm away from the top surface of the rail, the elastic parameter in the axial direction of the arm is an important index for measuring whether the collector shoe can be tightly attached to the third rail for a long time. Therefore, accurate measurement of the parameters is an important basis for ensuring that the collector shoe is kept running in a safe state.
