In the figure: the device comprises a distributing trolley 1, a frame 1.1, wheels 1.2, rollers 1.3, a speed reducer 2, a generator 3, a load circuit 4, a load resistor 4.1, a switch 4.2, a belt conveyor 5 and a storage bin 6.
The specific implementation mode is as follows:
as shown in fig. 1 to 3, an inertia slippage prevention device for a cloth trolley comprises a speed reducer 2, a generator 3 and a load; the speed reducer 2 and the generator 3 are fixed on a frame 1.1 of the material distribution trolley 1, any wheel 1.2 of the material distribution trolley 1 is in transmission connection with an input shaft of the speed reducer 2, and an output shaft of the speed reducer 2 is in transmission connection with a power input shaft of the generator 3; the power output end of the generator 3 is electrically connected with a load, the load is formed by connecting a plurality of load circuits 4 in parallel, each group of load circuits 4 is electrically connected with the power output end of the generator 3, each group of load circuits 4 is formed by connecting load resistors 4.1 and switches 4.2 in series, the resistance values of the load resistors 4.1 in each group of load circuits 4 are different, when the moving direction of the cloth trolley 1 is consistent with the belt conveying direction of the belt conveyor 5, the load circuit 4 to be connected is selected according to the belt conveying speed of the belt conveyor 5, and the larger the belt conveying speed of the belt conveyor 5 is, the larger the resistance value of the connected load circuit 4 is, and the larger the consumed energy is; the wheel 1.2 of the cloth trolley 1 drives the input shaft of the speed reducer 2 to rotate through a chain, after the torque is increased through the speed reducer 2, the output shaft of the speed reducer 2 drives the generator 3 to rotate through a belt to generate electricity, the electricity generated by the generator 3 is transmitted to the switched-on load circuit 4 to do work and be consumed, the larger the resistance value of the load circuit 4 is, the larger the torque required by the power input shaft of the generator 3 is, the larger the torque output by the wheel 1.2 to the input shaft of the speed reducer 2 is, and the cloth trolley 1 and the wheel 1.2 move together, so that the kinetic energy of the consumed cloth trolley 1 is increased; therefore, the work generated by the generator 3 is almost offset with the kinetic energy of inertial slippage transmitted to the cloth trolley 1 by the belt conveyor 5, so that the moving speed of the cloth trolley 1 is almost the same as the driving speed of a driving device of the cloth trolley 1, the friction time of a brake pad is reduced in the parking process, the abrasion of the brake pad is reduced, the service life of the brake pad is prolonged, the replacement frequency of the brake pad is reduced, and the normal operation of a mineral separation production line is ensured;
because the cloth trolley 1 needs to stop cloth, the generator 3 cannot rotate when the cloth trolley is stopped, the generator 3 cannot generate stable current and can only directly consume, and the cloth workshop has no temperature requirement, so that the resistor is selected to generate heat and do work to consume, and the load resistors 4.1 with different resistance values are selected according to different belt speeds, the corresponding switches 4.2 are switched on, the load resistors 4.1 are connected into a circuit to do work to consume electric energy, and further the kinetic energy of the cloth trolley 1 is consumed.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
