Technical Field

[0001] The utility model relates to the technical field of drilling equipment, in particular to a connecting mechanism connecting a water source drilling rig and a logging winch sensor device. Background Art

[0002] Water source drilling rigs are mainly used in drilling projects such as water source development and mine construction.

[0003] The water source drilling rig is used to enter the relatively shallow exploration depth of coalbed methane and shale gas fields. These fields require full-well logging work. Tracking the well depth is very important for logging work. If the well depth tracking is inaccurate, all other parameters will be wrong. Therefore, it is particularly important to connect the water source drilling rig with the logging winch sensor device.

[0004] However, the existing water source drilling equipment does not have a mature device to connect with the logging winch sensor, which results in inaccurate well depth tracking. Sometimes, it is necessary to manually calculate the well depth by measuring the length of the drilling tool, which brings great inconvenience to the construction. Utility Model Content

Through this device, the rotation of the TSJ3000 / 445 water source drilling rig winch transmits a signal to the logging sensor, so as to track the well depth.

[0026] Both ends of one side of the bottom end of the steel plate 1 are rotatably connected with articulated frames 12, and the two articulated frames 12 are rotatably connected to the two ends of one side of the top end of the bottom plate 13, and a slide groove 18 is provided on the other side of the bottom end of the steel plate 1 and the other side of the top end of the bottom plate 13.

Through this device, the rotation of the TSJ3000 / 445 water source drilling rig winch is used to transmit a signal to the logging winch sensor 11, so as to track the well depth. This device consists of four bearing seats and three large, medium and small gears. The four bearing seats are fixed to a 14cm×33cm steel plate 1 by bolts. The two ends of one transmission shaft are connected to the medium and small gears, and one end of the other transmission shaft is connected to the large gear 6.
