Self-triggering magnetic control type anti-overspeed system for moving wheel rail

Abstract

The invention discloses a self-triggering magnetic control type anti-overspeed system for a moving wheel rail. The system comprises a mounting block, a rotatable wheel shaft is arranged on the side wall of the mounting block in a penetrating mode, a rotating wheel is fixedly connected to the side wall of the wheel shaft, and two permanent magnet rings are fixedly embedded in the side wall of the mounting block. Two containing cavities are formed in the rotating wheel, fixing plates are fixedly connected to the inner walls of the two containing cavities correspondingly, first copper wires and second copper wires are fixedly inserted into the side walls of the two fixing plates correspondingly, resistor rods are fixedly connected to the inner walls of the two containing cavities correspondingly, and the side walls of the two resistor rods are slidably sleeved with conductive plates correspondingly. Two circular cavities are formed in the rotating wheel. When the running speed of a deviceis too high, a good deceleration effect can be achieved, the situation that the device deviates from a rail due to the too high running speed is prevented, the safety performance of the device is improved, an external power source is not needed, and the economic cost of the device is saved.

Description

technical field [0001] The invention relates to the related technical field of moving wheel-rail equipment, in particular to a self-triggering magnetically controlled overspeed prevention system for moving wheel-rail. Background technique [0002] In the environment of building construction and factory workshops, it is often necessary to transport some objects or goods, and some wheel-rail transportation tools are usually used in the transportation process, such as some roadway trolleys used to transport coal mines and steel products etc. During transportation, in order to prevent these transportation equipment from being too fast, some safety devices for deceleration are usually set. [0003] The existing safety devices are generally mechanical anti-overspeed hooks arranged on the moving wheels. These anti-overspeed hooks are prone to deformation due to repeated strong impacts after long-term use, resulting in the failure of the device. The overall anti-overspeed performan...

Problems solved by technology

[0003] The existing safety devices are generally mechanical anti-overspeed hooks arranged on the moving wheels. These anti-overspeed hooks are prone to deformation due to repeated strong impacts after long-term use, resulting in the failure of the device. The overall anti-overspeed performance is reduced, and some electronic brake devices have appeared later. Compared with the anti-overspeed hook, these devices have improved anti-overspeed performance, but they need an external power supply when used, so the economic cost of the device is greatly increased. , in order to solve the above problems, it is necessary to design a self-triggering magnetic control anti-overspeed system for moving wheel rails
