| titleOfInvention | A roof fall rescue device in a coal mine |
| abstract | The utility model discloses an underground coal mine roof fall rescue device, which comprises a bottom plate, a support mechanism, a lighting mechanism and a lighting lamp. The bottom of the bottom plate is provided with a universal wheel with multiple sets of universal wheels, and the upper surface of the bottom plate is fixedly connected with a The hydraulic rod is in multiple groups, one end of the hydraulic rod is fixedly connected with a connecting plate, and a support mechanism is installed on both sides of the bottom plate. The support mechanism includes an extension block, an electric telescopic rod and a support plate. The extension block The bottom is fixedly connected with an electric telescopic rod, and one end of the electric telescopic rod is fixedly connected with a support plate. The support plate of the utility model is directly in contact with the ground, which increases the force-bearing area and can support more stably, and prevents the universal wheel from being damaged due to excessive force; the operation of the lighting lamp provides a good environment for the movement of the device, which is easy to find The wounded underground can also be used as a light source prompt to inform the wounded that rescuers are coming. |
