Problems solved by technology
Drill pipe tongs also need to be fully remote operated or to realize PLC programmable program operation; the two positioning handles used to align the notch of the original drill pipe tongs are rotating parts, and the rotating parts follow the drill wire during rotation. The screwing in and out of the buckle is used for axial displacement, so manual operation has been used for many years. Manual operation is relatively cumbersome, inefficient and has safety risks. Therefore, it is necessary to develop a remote alignment of drill pipe tongs without manual operation. Notch positioning device and its control method, after searching, no cases identical with the technical solution of the present invention were found

Embodiment Construction
[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0029] Such as Figure 1 to Figure 7 The drill pipe tongs remote notch positioning device shown in the upper tong notch is in the aligned state, the shackle positioning cylinder 11 has no rod cavity ventilation, the piston rod and the pressing rod A13 are hinged and protruded by the cylinder connecting pin A27, and the pressing rod A13 is pushed Rotate around the pressure rod pin A25, the free end of the pressure rod A13 is from the E position to the F position, press the shackle pin A6 from the side hole of the bracket A7 into the groove A fixed on the upper limit plate 10 of the floating body 23, and pass through one end of the cylinder 11 The built-in sensor confirms that the breakout pin A6 is inserted into the limit plate 10, the cylinder 11 is automatically retracted, and the free end of the pressure rod A13 is lifted to the E position, which is confirm...

The invention relates to a drill pipe tong remote notch aligning and positioning device, which is characterized by comprising a support plate, an upper positioning assembly, a lower positioning assembly, a floating body and a position limiting plate, wherein the support plate is arranged at the side surface of a lower case of a drill pipe tong; the upper positioning assembly and the lower positioning assembly are fixedly arranged on the support plate; and the position limiting plate is arranged on the floating body. The drill pipe tong remote notch aligning and positioning device has the advantages that according to the technical scheme, two press rods are pushed through two positioning air cylinders fixed on a lower casing of the drill pipe tong; and the action of two plug pins is realized. The two plug pins respectively realize buckling and unbuckling notch aligning actions; the two plug pins are connected through a connecting rod; the effects that one plug pin is inserted, but the other plug pin is automatically pulled out are achieved; the air cylinder can be automatically reset, so that the two positioning press rods are lifted to leave a space for the axial displacement of a rotating element of the drill pipe tong; a back tong positioning device uses a single positioning air cylinder to realize the plugging and unplugging of the two plug pins; and the remote control accuracy and automatic operation of the remote control can be realized through sensors of the positioning air cylinders.
Description
technical field [0001] The invention relates to a remote notch positioning device for drill pipe tongs, in particular to a remote notch positioning device for drill pipe tongs without manual operation and a control method thereof. Background technique [0002] In oil drilling operations, drill pipe tongs are frequently used to make and break drill pipes, drill collars and other drilling tools; with the continuous advancement of drilling technology and drilling rigs and other equipment, the degree of automation of drilling operations has been continuously improved. Drill pipe tongs also need to be fully remote operated or to realize PLC programmable program operation; the two positioning handles used to align the notch of the original drill pipe tongs are rotating parts, and the rotating parts follow the drill wire during rotation. The screwing in and out of the buckle is used for axial displacement, so manual operation has been used for many years. Manual operation is relati...
