Wired network transmission underground electric shoveling and conveying machine

Abstract

The invention discloses a wired network transmission underground electric shoveling and conveying machine. The wired network transmission underground electric shoveling and conveying machine comprisesan electric shoveling and conveying machine body and a cable rolling coiling block around which a mining cable is wound, and a rubber outer sheath of the mining cable is internally provided with three conductive cable cores, one kilomega reticle, one tensile steel wire and a grounding cable core and is fully filled with rubber filler. The cable rolling coiling block comprises a barrel and a casing pipe, and the casing pipe is connected with the electric shoveling and conveying machine body through a support plate. The casing pipe in the barrel is sleeved with a first installing plate, a reticle sliding ring, a second installing plate, three conductive cable core sliding rings and an insulating plate. The reticle sliding ring comprises a reticle sliding ring rotor, a reticle sliding ring stator, a stator installing fork, a rotor reticle port and a stator reticle port. The kilomega reticle is connected with a reticle in the electric shoveling and conveying machine body through the rotorreticle port and the stator reticle port. The conductive cable cores are connected with a power cable of the electric shoveling and conveying machine body through the conductive cable core sliding rings correspondingly. According to the wired network transmission underground electric shoveling and conveying machine, the application range is enlarged, the problem about network signal transmissionis effectively solved, and the operation efficiency and safety are greatly improved.

Description

Technical field: [0001] The invention relates to a remote control trackless device, in particular to an underground electric scraper with wired network transmission, which belongs to the technical field of mining engineering machinery. Background technique: [0002] With the continuous development of network information technology, remote control trackless equipment has gradually entered the mine. For remote control of trackless equipment, information transmission is a crucial link. Within the operating range of trackless equipment, network signals must be effectively covered, and the transmission efficiency can meet the requirements of trackless equipment, so that trackless equipment can be used remotely. . However, the section of the underground roadway is small, and the roadway has many bends, resulting in serious network signal attenuation. The signal strength and rate cannot meet the application requirements of remote control trackless equipment, which limits the use o...

AI Technical Summary

Problems solved by technology

However, the section of the underground roadway is small, and the roadway has many bends, resulting in serious network signal attenuation. The signal strength and rate cannot meet the application requirements of remote control trackless equipment, which limits the use of remote control. At present, the main means of enhancing the signal is to arrange more in the underground. Signal base stations or laying more signal antennas, but this greatly increases the cost of infrastructure construction and operation. On the other hand, trackless equipment, especially scrapers, often work in the front line of mines. If antennas are laid in advance on the working surface, after blasting, The antenna is very easy to damage, the safety hazard of personnel maintenance is great, and the network cannot be effectively covered, which limits the application range and efficiency improvement of remote control trackless equipment to a certain extent
