Flameproof and intrinsically safe speed regulation control box control system for storage battery monorail crane

Abstract

The invention relates to the technical field of monorail cranes, and in particular relates to a flameproof and intrinsically safe speed regulation control box control system for a storage battery monorail crane. The system comprises a monitoring unit, a data analysis unit, a main controller, a display, a control key, power motors, a hydraulic telescopic rod I, a hydraulic telescopic rod II, a database and a memory, the database is used for recording forward turning radius node values, the monitoring unit is used for detecting the operation state of the power module of the monorail crane and transmitting obtained data to the data analysis unit, and the data analysis unit is used for comparing and analyzing the obtained data with data in the database. In the invention, the main controller is used for controlling the rotating speeds of two power motors respectively and accelerating the power motor on the low-speed side, so that the side with high pressure is prevented from bearing an overlarge load, and the service lives of the power motors and the storage battery are prolonged.

Description

technical field [0001] The invention relates to the technical field of monorail cranes, in particular to a control system of a flameproof and intrinsically safe speed regulation control box for battery monorail cranes. Background technique [0002] The battery monorail crane is an auxiliary transport locomotive for underground coal mines. Driving on the monorail, it can not only transport materials, personnel and equipment, but also complete simple lifting and hoisting of underground equipment. It is a multi-functional, high-efficiency, and multi-purpose underground auxiliary transport vehicle. When on a flat road or uphill, the battery provides power to complete the traction work; when going downhill, the kinetic energy and potential energy can be converted into electrical energy, recoiled to the battery, and automatic deceleration and braking are realized by energy feedback. [0003] The battery monorail crane uses the battery to supply power to the power motor. It does n...

AI Technical Summary

Problems solved by technology

[0003] The battery monorail crane uses the battery to supply power to the power motor. It does not provide power for the operation of the monorail crane. When the crane is cornering, due to the structural characteristics of the curved track, the rubbing wheel on one side is in close contact with the track, while the track on the other side is in loose contact. The speed difference between the two rubbing wheels is large. The conventional method of synchronous control of the power motor is adopted. , it will cause a high speed on one side and a small speed on the other side. In order to realize the smooth operation of the power module of the monorail crane, it is bound to drive the motor on the low speed side to increase the speed, forming a reverse current. After the speed is increased, the fast side is overloaded and power consumption The increase will affect the service life of the power motor and battery at the same time, and the existing battery monorail brake uses the power motor to convert potential energy into kinetic energy and the combination of friction and braking to decelerate, which has a low utilization rate of potential energy
