Background
With the advance and development of the coal bed gas industry, a plurality of exploration teams of coal fields also participate in the exploration and development of the coal bed gas. At present, most coal field drilling machines adopt a rope coring mode (XY-6, XY-8 and the like), when the drilling machines are used for logging coal bed gas, a winch sensor of a logging instrument (SK 2000C and the like) on the market at present is found to be designed based on the oil field drilling machines, and the winch sensor is installed on a roller of the drilling machine, monitors the rotation condition of the roller and converts the rotation condition into a drilling footage to log the coal bed gas; however, the existing rope core drilling machines (XY-6, XY-8, etc.) widely used for coal field exploration cannot obtain effective data if the winch sensors are forcibly installed according to the installation method of the oil field drilling machines because the rollers do not necessarily rotate during drilling. Therefore, in order to mount the winch sensor on the wire-line core drill (XY-6, XY-8, etc.) and smoothly perform logging work, a device capable of solving the above-mentioned technical problem is required so that a coal field exploration team can perform exploration work of coal bed gas using the existing wire-line core drill (XY-6, XY-8, etc.).
Disclosure of Invention
The utility model discloses a solve the winch sensor of present logging instrument (SK 2000C etc.) can't use the technical problem on the rope coring drilling machine of coal field exploration, provide an auxiliary installation device that is used for the logging winch sensor of rope coring drilling machine.
The utility model discloses an adopt following technical scheme to realize: an auxiliary mounting device for a logging winch sensor of a rope core drilling machine comprises a winch frame; a transmission shaft is horizontally and rotatably supported on the winch frame, and a large hub and a small hub are fixed on the transmission shaft; the large hub and the small hub are respectively wound with a first steel wire rope and a second steel wire rope, one end of each steel wire rope is fixed with the hub, and the other end of each steel wire rope is led out of the winch frame after bypassing the hubs; the leading-out end of the first steel wire rope is connected with a drilling machine, and the leading-out end of the second steel wire rope is connected with a weight; one end of the transmission shaft extends out of the installation position; the winch sensor is fixed with the winch frame, and the inner ring of the winch sensor is fixedly connected with the extending end of the transmission shaft.
The working principle is as follows: when the drilling machine drills downwards, the first steel wire rope is driven to move, and the large hub and the transmission shaft on the winch frame are correspondingly driven to rotate, so that the winch sensor can obtain a pulse electric signal, and the pulse electric signal can be converted into drilling footage data through the computer; when the drilling machine drills a drill upwards and connects a single, the second steel wire rope wound around the small hub moves downwards quickly under the pull of the balance weight to drive the transmission shaft to rotate together, so that the winch sensor can also obtain a pulse electric signal, the pulse electric signal is transmitted back to the logging house and then converted into the rotating speed of the transmission shaft through computer operation, and then the computer is combined with other drilling information such as hook pull force to judge the drilling state such as drill lifting or single connection.
The device can effectively solve the problem that logging winch sensor can't be installed in the supporting of coal field rig for its function is measured in the performance of winch sensor, and installs succinctly quick, convenient to use.
The device is directly welded on the logging roof, is simple, practical, firm, reliable and economical, and improves the installation efficiency of logging instruments in coal bed gas exploration.
