Embodiment Construction

[0036] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be pointed out that the description and sequence of specific structures in this section are only descriptions of specific embodiments, and should not be considered as limiting the protection scope of the present invention.

[0037] The main improvement of the embodiment of the present invention is that support seats are provided at both ends of the main shaft, so that the explosion-proof cable reel can be supported on both sides, so that the overall force is uniform, and the main shaft uses a partial hollow structure, which can effectively realize the working chamber. The isolation from the wiring cavity meets the national coal mine production requirements, and the flameproof effect is better; the wiring cavity is f...

Abstract

The invention relates to a flameproof cable reel and coal mine machinery. The flameproof cable reel includes a cylinder body, a baffle plate and a main shaft; the baffle plate includes a first baffle plate and a second baffle plate, and the first baffle plate and the second The baffles are respectively arranged at both ends of the barrel; the main shaft is set as a partial hollow structure, and the two ends of the main shaft are movably mounted on the first baffle and the second baffle through bearings; the two ends of the main shaft are respectively fixedly installed with left and right supports. seat. The main shaft is movably installed on the first and second stop discs through bearings, and the main shaft is supported by the left support and the right support to realize double support for the main shaft, so that the explosion-proof cable reel is not easy to tilt and the force is even.

Description

technical field [0001] The invention relates to coal mine machinery, in particular to a flameproof cable reel and coal mine machinery. Background technique [0002] At present, in the coal mining industry, the coal mining machinery that is often used in the roadway construction process includes continuous coal mining machines, shuttle cars, and continuous transportation systems. These equipments also have shortcomings while accelerating mining speed and improving operating efficiency. It is their power cables that need to be retracted as the equipment moves. For example, the JOY12CM continuous coal mining machine in the United States has a cable cross-sectional area of ​​about 95 square millimeters and a length of 100 meters, which transmits a current of 1140 volts and 400 amperes. However, it can only be dragged manually when moving, which is labor-intensive. It is extremely inconvenient, and it is completely exposed under the empty roof during the production process, and ...
