The invention relates to an
electric trolley frequency conversion speed-regulating locomotive. The device mainly overcomes the defects that as the existing pneumatic or handwheel mechanisms
brake and respond slowly, the
braking distance is long, the braking performance is poor, the
brake block is easy to wear, etc. The device also solves the technical problems that owning to large braking force or mechanical reasons, the locomotive wheels lock so as to cause
derailment phenomenon and the like. The keys of the technical scheme of the invention are as follows: the locomotive comprises a car frame
assembly and a sanding device, wherein a cab
assembly is arranged on the front end of the car frame
assembly, a walking device and a
frequency conversion speed-regulating
electric control system are arranged on the car frame assembly, two anti-lock
brake devices are separately arranged on the two sides of the walking device; and each anti-lock brake device adopts a normally closed electromagnetic time
delay braking device, and the braking device mainly comprises a brake disc spring, a cylinder body, a cylinder column, an electromagnetic iron core, a brake lever, a clamping plate brake body, a brake disc, an electromagnetic
pressure switch device and an
electric trolley locomotive power-off anti-lock brake device. The
electric trolley frequency conversion speed-regulating locomotive can adapt to various hauling operating conditions of the industrial-mineral
electric locomotive and the technology of the invention can be used to modify old industrial-mineral electric locomotives.
