Double-boot linkage side contact current collector for manually and pneumatically taking off boots

Abstract

The invention discloses a double-boot linkage side contact current collector for manually and pneumatically taking off boots. The current collector comprises a base assembly, an upper arm assembly, alower arm assembly, a carbon sliding plate bracket, a carbon sliding plate assembly, a stretching assembly and a boot taking-off assembly, the tail end of the upper arm assembly is hinged to the baseassembly, the tail end of the lower arm assembly is hinged to the base assembly, the stretching assembly is connected between the bottom of the middle of the upper arm assembly and the base assembly,and the two ends of the stretching assembly are hinged to the upper arm assembly and the base assembly respectively. Two carbon sliding plate brackets are arranged at the head ends of the upper arm assembly and the lower arm assembly, each carbon sliding plate bracket is simultaneously hinged with the head ends of the upper arm assembly and the lower arm assembly, and the carbon sliding plate assemblies are arranged at the bottoms of the carbon sliding plate brackets; the boot taking-off assembly is arranged on the base assembly; the device is provided with a manual and pneumatic integrated shoe taking-off mechanism, the structure is simple, operation is convenient, the stability of the contact force between the carbon sliding plate assembly and the third rail is guaranteed through the tension of the stretching assembly, the side contact current collection effect is good, and later inspection and maintenance are facilitated.

Description

technical field [0001] The invention relates to a side contact current collector for manual and pneumatic shoe removal, which belongs to the technical field of rail transportation. Background technique [0002] Rail transit is becoming more and more popular with its advantages of fast, punctual, large capacity, low energy consumption and less pollution; because the contact rail system has the characteristics of large carrying capacity and low maintenance cost, it is widely used in electrified rail transit The contact rail power supply system is a power supply method that transmits the electric energy on the transmission line to the vehicle through the current receiver installed on the vehicle bogie; for the qualified current receiver, it is required to be in the process of movement, Always keep the contact force with the power supply contact rail stable, too large or too small contact force will affect the quality of current receiving, increase the wear of the carbon slide p...

[0002] Rail transit is becoming more and more popular with its advantages of fast, punctual, large capacity, low energy consumption and less pollution; because the contact rail system has the characteristics of large carrying capacity and low maintenance cost, it is widely used in electrified rail transit The contact rail power supply system is a power supply method that transmits the electric energy on the transmission line to the vehicle through the current receiver installed on the vehicle bogie; for the qualified current receiver, it is required to be in the process of movement, Always keep the contact force with the power supply contact rail stable, too large or too small contact force will affect the quality of current receiving, increase the wear of the carbon slide plate of the current collector and the power supply contact rail, and increase the operation and maintenance costs; according to the installation method of the current collector According to the difference, current collectors can be divided into upper contact current collectors, lower contact current collectors and side contact current collectors. At present, rail transit mainly uses upper contact current collectors and lower contact current collectors. However, the side contact current collector has not been widely used due to the inconvenient operation, and most of the existing side contact current collectors take off the boots without boot operation or manual boot removal, which is not easy to use, and it is not convenient for the later stage inspection and maintenance
