Embodiment Construction
[0019] The flameproof cable rolling device of the present invention can be applied to various mobile devices that need to be powered by power cables in underground coal mines. The layout of each unit should be designed in a targeted manner. The size and structural strength of the device should meet the explosion-proof requirements, the overall size (especially the height) of the device should meet the height requirements of the underground roadway, and the number of cables stored in the cable drum structure should meet the needs of the excavation depth.
[0020] Hereinafter, taking the American JOY12CM series continuous coal mining machine (hereinafter referred to as the continuous mining machine) as an example, the preferred embodiment of the present invention will be described in detail in conjunction with the accompanying drawings. In this preferred embodiment, the coiled cable device is installed in the middle of the upper part of the continuous mining machine, and each co...

An explosion-proof cable coiling device comprises a cable drum assembly, an explosion-proof current-collecting device and a drive device. Wherein, the cable drum assembly is composed of a cable drum, a baffle plate and a hollow principal shaft. The baffle plate is arranged at both ends of the cable drum. The drive device is composed of a motor and a drive mechanism. The cable drum is driven by the drive device to rotate along the principal shaft. In addition, the explosion-proof current-collecting device is arranged in the cable drum and composed of an explosion-proof box, an electric brush assembly and a slide ring assembly. The electric brush assembly is arranged on the explosion-prevention box and rotates on the slide ring assembly fixed on the principal shaft along the cable drum. The electric brush assembly is electrically connected with the cable. Besides, the slide ring assembly is connected with a device waiting for power supply through a cable. The present invention is suitable for coal mines and other specific environments and coils and uncoils power cables of mobile devices with large transmission current and high voltage.
Description
technical field [0001] The invention relates to a cable rolling device, in particular to a flameproof cable rolling device used for retracting and retracting power cables of underground mobile equipment in coal mines. Background technique [0002] In recent years, in the coal industry, more and more large-scale mobile equipment has been used in short-wall mechanized mining and working face tunneling, such as imported 12CM series continuous coal mining machines, shuttle cars, and continuous transportation systems. These devices also have disadvantages when speeding up mining speed and improving operating efficiency, that is, their power cables need to be retracted along with the movement of the device. For example, the American JOY12CM continuous coal mining machine has a cable cross-sectional area of about 95mm 2 , is more than 100 meters long, and transmits a current of 1140 volts and 400 amps. However, it can only be dragged manually when moving, which is labor-intensiv...
