Abstract
The invention relates to the technical field of devices for detecting bending deviation of thin and long shafts, in particular to a device for detecting deviation of a CrMo alloy deep sea oil drill pipe. The device comprises a frame body, a screw and a guide rod which are horizontally arranged on the frame body, a sliding block which is driven by rotation of the screw to move on the guide rod, and detectors which are fixedly connected with the sliding block, wherein each detector comprises a shell, supporting blocks which are arranged at the ends of the shell and a detection head on the top of the shell; acoustic detectors are fixedly arranged on the supporting blocks; a spring is arranged between the supporting blocks and the detection head; the acoustic detectors are connected with a singlechip through a guide line; and the singlechip is connected with a display and an alarm respectively. According to the device, the detectors which are arranged on the screw are used for detecting the drill pipe, detection signals are processed by the singlechip, then a calculation result is displayed by the display, or the alarm sends out an alarm signal, so that operation staff can timely know and process the deviation condition.
Description
Technical field
The present invention relates to slender axles error measuring means technical field, be specifically related to CrMo alloy deep-sea oil drilling rod error measuring means.
Background technology
CrMo alloy deep-sea oil drilling rod need to carry out operation under complicated rugged environment, thereby have characteristics such as corrosion-resistant, high strength, high-mechanical property, usually the both ends of drilling rod are thick, middle thin, long 8～the 12m of drilling rod, CrMo alloy deep-sea drilling rod is as the slender axles parts, utilizing lathe to add man-hour, is one of typical difficult processing work kind.Mainly rely at present operator's experience for the processing of slender axles, and high to operator's technical merit requirement, production efficiency is low, and product quality is very unstable.Why the slender axles parts are difficult to processing, be due to length diameter ratio greater than 20, poor rigidity, and can produce due to the Action of Gravity Field of self the flexural deformation phenomenon if deviation surpasses 3mm, can't be carried out the cylindrical car and cut.
At present, there is no at home and detect the specialized equipment that its deviation is measured in slender axles flexural deformation, only begin feed at lathe and can know just whether whether drilling rod is crooked, can process.And the work of processing drilling rod front and continued, the Installation and Debugging of unit clamp needed more than one hour, in case drill pipe buckling must waste the time that " unit clamp " installed, this makes working (machining) efficiency greatly reduce.
Summary of the invention
The purpose of this invention is to provide a kind of CrMo alloy deep-sea oil drilling rod pick-up unit that can accurately detect the crooked deviation of drilling rod.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: CrMo alloy deep-sea oil drilling rod error measuring means, comprise support body, laterally be located at leading screw and guide rod on described support body, rotarily drive slide block mobile on guide rod, the detecting device that is fixedly connected with described slide block by described leading screw, described detecting device comprises housing, is located at the back-up block of described shell end and the detecting head of described case top respectively, be installed with acoustic detector on described back-up block, be provided with spring between described back-up block and detecting head; Described acoustic detector is connected with single-chip microcomputer by wire, and described single-chip microcomputer is connected with alarm with display respectively.
Further, described detecting device is 4.
The present invention has following beneficial effect: CrMo alloy deep-sea oil drilling rod error measuring means of the present invention, by the detecting device of being located on leading screw and guide rod, drilling rod is detected, and its detection signal is shown operation result by display after single-chip microcomputer is processed or send whether qualified signal by alarm, the convenient operation personnel can in time understand the deviation situation and process, can identify exactly the degree of deviation of drilling rod, significantly improve working (machining) efficiency.In addition, the present invention has the characteristics such as reasonable in design, that detection is accurate, cost is low.

Fig. 2 is the structural representation of the embodiment of the present invention two.
Fig. 3 is the structural representation of detecting device in the present invention.
Embodiment
Embodiment one:
As Fig. 1, shown in Figure 3, CrMo alloy deep-sea oil drilling rod error measuring means, comprise support body 1, laterally be located at leading screw 2 and guide rod 3 on described support body 1, rotarily drive slide block 4 mobile on guide rod 3, the detecting device 5 that is fixedly connected with described slide block 4 by described leading screw 2, described detecting device 5 comprises the detecting head 8 at housing 6, the back-up block 7 of being located at respectively described housing 6 ends and described housing 6 tops, be installed with acoustic detector 9 on described back-up block 7, be provided with spring 10 between described back-up block 7 and detecting head 8; Described acoustic detector 9 is connected with single-chip microcomputer 11 by wire, and described single-chip microcomputer 11 is connected with alarm with display 12 respectively and is connected; In the present embodiment, when carrying out the detection of drilling rod deviation, drilling rod 14 is located on support body, be arranged in parallel with leading screw and guide rod, choose a check point on drilling rod, check point selected on the detecting head that is arranged on detecting device on slide block and drilling rod contacts, when drilling rod rotates along its central shaft, if there is deviation in this drilling rod, detecting head will be subjected to displacement in the horizontal direction, and the acoustic detector of detecting device inside sends the displacement data of detecting head to single-chip microcomputer by sound wave.The second check point is chosen in other positions on drilling rod, thereby leading screw rotatablely moves and move to the position of the second check point with movable slider on guide rod, same method sends the displacement data of detecting head to single-chip microcomputer by acoustic detector, by that analogy, can get 8 to 10 check points on a drilling rod, send the displacement data of detecting head to single-chip microcomputer by acoustic detector.Whether qualified after single-chip microcomputer is processed, operation result shown by display or send signal by alarm, the convenient operation personnel in time understand the deviation situation and process.Because spring has retractility, thereby the effect of the present embodiment medi-spring is to make the detecting head of detecting device to contact with drilling rod always, improves measuring accuracy.Test shows, if do not adopt the structure of detection head, directly acoustic detector is aimed at drilling rod and is detected its crooked deviation, and its data are inaccurate, trace it to its cause, and is to have the foreign material such as greasy dirt on drilling rod, has affected accuracy of detection.
Embodiment two:
As shown in Figure 2, described detecting device 5 is 4, and in the present embodiment, 4 detecting devices are set can be detected drilling rod simultaneously, improves detection efficiency.
Explanation is at last, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, other modifications that those of ordinary skills make technical scheme of the present invention or be equal to replacement, only otherwise break away from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of claim scope of the present invention.
