Abstract
The utility model discloses a novel tool joint torque detection testing machine. A pair of clamping pincers and a pair of rotating pincers used for clamping and rotating two drilling rod segments connected with an uncoupling head are respectively arranged on a frame. The pair of clamping pincers comprises a jaw plate support. A jaw plate is arranged on the jaw plate support. The jaw plate support is connected with a piston rod of a magnetic cylinder. A pulling force sensor is arranged on the jaw plate support. Three magnetic switches arranged on the magnetic cylinder are respectively used for detecting a cylinder rising-in-place position, a cylinder middle position and a cylinder falling-in-place position. The utility model aims to provide a tool joint torque detection testing machine characterized by reasonable structure, data accuracy, safety, reliability, simple operation, and high efficiency.
Description
Technical field
The utility model relates to a kind of drill pipe sub moment of torsion and detects testing machine.
Background technology
Oil drill rocker manufacturing plant carries out for several times upper, the shackle detection test (be generally three time) of different torque values to drill pipe sub by moment of torsion is set according to customer requirement.Owing to not having at present special-purpose drill pipe sub moment of torsion to detect testing machine, each oil drill rocker manufacturing plant can only replace with common screw-on machine.Existing screw-on machine main folder clencher is generally realized clamping by six hydraulic cylinders, on a hydraulic cylinder, shackle, because this structure can only swing certain angle, can not continuous rotation, there will be moment of torsion not reach the phenomenon of setting value during above button, may need repeatedly to unclamp, clamping, upper button operation, like this equally during shackle.This screw-on machine complex operation, the easy misoperation of operating personnel, and production efficiency is low.In addition, upper, the shackle torque value of existing screw-on machine is converted and obtained by the force value of hydraulic system, and error ratio is larger.
The utility model content
The purpose of this utility model be to provide a kind of rational in infrastructure, data are accurate, safe and reliable, easy and simple to handle, high efficiency drill pipe sub moment of torsion detects testing machine.
Technical solution of the present utility model is:
A kind of drill pipe sub moment of torsion detects testing machine, comprises frame, it is characterized in that: fill respectively clamping clip, rotary clamp that two sections drilling rods that the uncoupling head is connected are clamped and rotate on frame; Clamping clip comprises jaw plate frame, fill jaw on jaw plate frame, jaw plate frame is connected with the piston rod of magnetic air cylinder, fills pulling force sensor on jaw plate frame, three magnetic switchs are housed on magnetic air cylinder, detect respectively cylinder rise put in place, cylinder meta, cylinder descend three positions that put in place
Rotary clamp, clamping clip all adopt climbing roller to clamp form.
The utility model is rational in infrastructure, and have following advantages: rotary clamp, the clamping clip of this drill pipe sub moment of torsion detection testing machine all adopt the mode of climbing roller clamping, and rotary clamp energy continuous rotation, make clamping force and moment of torsion simultaneous growth, not there will be moment of torsion not reach the phenomenon of setting value.Torque value is by the sensor measurement be arranged on the clamping clip jaw plate frame, irrelevant with pressure size and the pipeline loss of hydraulic system, thereby makes the torque value that records more accurate.Clamping clip has adopted the magnetic clamping cylinder, and three magnetic switchs are housed on magnetic air cylinder, detect respectively cylinder rise put in place, cylinder meta, cylinder descend three positions that put in place.More easily make jaw more easily fall off to meta, and jaw open maximum position, so that the advance and retreat station of drill pipe sub action and be convenient to change the jaw of different model.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the clamping clip structural representation.
Embodiment
A kind of drill pipe sub moment of torsion detects testing machine, comprises frame 1, fills respectively clamping clip 2, rotary clamp 3 that two sections drilling rods that the uncoupling head is connected are clamped and rotate on frame; Clamping clip comprises jaw plate frame 4, dress jaw 5 on jaw plate frame, jaw plate frame is connected with the piston rod of magnetic air cylinder 6, dress pulling force sensor 7 on jaw plate frame, three magnetic switchs 8 are housed on magnetic air cylinder, detect respectively cylinder rise put in place, cylinder meta, cylinder descend three positions that put in place, the lifting of magnetic air cylinder is controlled by the two automatically controlled guiding valves 9 of 3 position-5 way, rotary clamp is controlled by electro-hydraulic reversing valve 10; In drill pipe sub, the shackle torque value measured by the pulling force sensor 7 be contained on clamping clip
Rotary clamp, clamping clip all adopt climbing roller to clamp form.
