The invention provides a variable-frequency heating system for a draw gear buffer system. The variable-frequency heating system mainly comprises a controller, a memory, a working circuit, a feedback circuit, a debugging computer and a heating device. According to the invention, the original mode of only heating a coupling end surface of the draw gear buffer device is changed into the mode of heating all key parts of the draw gear buffer device in a full-range grading manner, so the problem that the coupling end surface of the draw gear buffer device cannot be coupled and grouped due to freezing, clamping and stagnation and the like can be prevented; meanwhile, the loss or reduction of the function of the draw gear buffer device in the low-temperature environment or the loss or reduction of the function of the draw gear buffer device due to insufficient thrust of a pneumatic assembly are avoided; and function implementation and driving safety of the draw gear buffer device in the high and cold environment are guaranteed.
Description
technical field [0001] The invention relates to a heating device for a coupler device, in particular to a frequency conversion heating system and a heating device for a coupler buffer system, belonging to the technical field of coupler buffering. Background technique [0002] The coupler buffer device is one of the key parts of the rail transit vehicle. In order to ensure the normal use of the coupler buffer device in a low temperature environment, an electric heating device is usually used to heat the coupling end face. [0003] At present, the conventional heating system for the coupler buffer device usually adopts a constant pressure and constant power heating method. Image 6 , 7 As shown, switch knife 1 and circuit breaker 2 are used to control the overall on-off control of the heating system, the state of the electric heating belt 5 installed on the hook body 6 is controlled through the normally open contactor 3, and the pin 4 is used to realize the division of the hea...
