Document Type and Number:
WIPO Patent Application WO/2024/045380
Kind Code:
A1
Abstract:
A current collector shoe lifting and descending device, comprising a shoe descending mechanism and a shoe lifting mechanism. The shoe descending mechanism comprises a shoe descending insulation rope assembly, a support plate (11) and a support plate spring (10). The shoe lifting mechanism comprises a shoe lifting insulation rope assembly, a lock hook (5) and a lock hook spring (3). The shoe lifting insulation rope assembly and the shoe descending insulation rope assembly comprise a shoe lifting handle and shoe descending handle (13, 14), a shoe lifting insulation rope (2), a shoe descending insulation rope (1), a spring barrel (15) and end rings (21); the spring barrel (15) penetrates through a vehicle body (18) and is fixedly connected to the vehicle body (18); the shoe lifting insulation rope (2) and the shoe descending insulation rope (1) pass through the spring barrel (15) to extend out; one end of the shoe lifting insulation rope (2) and one end of the shoe descending insulation rope (1) are connected to the shoe lifting handle and shoe descending handle (13, 14); the other end of the shoe descending insulation rope (1) is connected to the support plate (11) by means of an end ring (21); rotation of the support plate (11) can drive an upper arm rod (9) to rotate, so as to enable a sliding plate (7) of the current collector shoe to separate from a power supply rail (6); the other end of the shoe lifting insulation rope (2) is connected to the lock hook (5) by means of an end ring (21); and rotation of the lock hook (5) can relieve a constraint thereof on a sliding-plate shaft (8) of the current collector shoe, so as to enable the sliding plate (7) of the current collector shoe to be in contact with the power supply rail (6). By means of using the insulation ropes to transmit acting force, the lifting and descending device can be conveniently arranged at different positions, and operators can conveniently perform operation in vehicles, thereby improving the safety of the operators.
