Embodiment Construction

[0041] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0042] The composition of the mine trackless transport locomotive according to the invention is shown in FIG. 1 . It is mainly composed of driver's cab 5, driving device 6, battery box 7, electric control box 8, carrying trolley 9, lifting device, connecting rod 3, hydraulic system, and electric control system. The trackless transport locomotive relies on the carrying trolley 9 to hang and run under the guide rail.

[0043] 1. Driver's cab 5: There are two front and rear cabs, which are respectively installed at the two ends of the trackless transport locomotive. In the driver's cab 5, there is a control display stand 10, and a control panel and a display panel are housed on the control display stand 10 for the driver to operate. There is no distinction between the two cabs, and the operating rights are equal. Whichever operates first will ge...

Abstract

The invention relates to a mine trackless transport locomotive used for underground subsidiary transport, which comprises a pre driver chamber and a post driver chamber, a driving device, a battery, a load-bearing wheelbarrow, a hoist apparatus, a hydraulic system, an electrical control system, etc. A traction motor in the driving device and a hydraulic pump motor of the hydraulic system both adopt three-phase AC motors, which are provided with AC by the battery through a transducer. The electrical control system comprises of a programmable controller, the transducer, a speed and direction sensor, a pressure sensor, a photoelectric conversion isolation plate, a dashboard, a display board, an intrinsic safety power source, an explosion septal and intrinsic safe electric control box, etc. The traction motor of the trackless motor and the hydraulic pump motor adopt alternating current motors which have the advantages of light weight, small size, low price, convenient maintenance and wide application. The direct current in the battery is transferred into three-phase alternating current by the transducer to reduce attack of starting current on the motors and the battery, prolong the service life of the motors and improve power factor. When the transport locomotive is running declivous, the kinetic energy can be transferred into electric power to charge the battery, so as to realize power regenerative braking.

Description

technical field [0001] The invention relates to a mine auxiliary transport system, in particular to an electric traction mine trackless transport locomotive, or a monorail crane, for auxiliary transport, simple lifting and hoisting in the mine underground level and inclined lanes. Background technique [0002] The trackless transportation system is a trackless transportation system that runs on a suspended monorail system, mainly for the auxiliary transportation of coal mines. It can not only transport materials, personnel and equipment, but also complete tasks such as simple lifting and hoisting of underground equipment; it is a multi-functional, high-efficiency, and multi-purpose underground auxiliary transportation equipment. A trackless transport locomotive is powered by a battery, and a DC motor is used to complete the traction work; the other trackless transport locomotive is drawn by an internal combustion engine. Explosion-proof DC motors are used for traction. The ...
