Abstract

A tapered taking device for broken ends of screws comprises a guide part, a transition part and a handheld part, wherein one end of the guide part is connected with one end of the transition part; the other end of the transition part is connected with one end of the handheld part; the longitudinal axes of the guide part, the transition part and the handheld part are on the same straight line; the area of the longitudinal cross section of the transition part becomes larger and larger from the end connected with the guide part to the end connected with the handheld part; a plurality of protruding ridges are arranged on the surface of the transition part. After the transition part of the tapered taking device is knocked into a drill hole in the center of the broken end of a screw, a tangential force is counterclockwise exerted to the tapered taking device, and the tangential force is transmitted to the broken end of the screw, so that the broken end of the screw can smoothly withdraw from a parent body along an original thread port.

Description

A kind of screw rod broken end cone is got device
Technical field
The utility model relates to a kind of flight-line maintenance utensil, especially a kind of taking-up instrument for larger-diameter screw rod broken end.
Background technology
When carrying out the plant equipment maintenance, run into sometimes the situation of bolt fracture in parent, for the screw rod broken end is taken out in parent, usually adopt drill through, hand hammer beats, flat chisel shovels out or the method such as gas cutting thawing, these methods are time-consuming, efficient is low, success rate is not high yet, the particularly screw rod broken end more difficult taking-up serious to larger diameter and corrosion, and sometimes also can damage the internal thread of parent, affect the function of equipment.
Summary of the invention
The utility model provides a kind of screw rod broken end cone to get device, its transition part is knocked in the boring at screw rod broken end center after, get device to cone in the counterclockwise direction and apply tangential force, tangential force passes to the screw rod broken end, makes it to withdraw from from parent along original mouth.
The purpose of this utility model is achieved in that a kind of screw rod broken end cone gets device, described screw rod broken end cone is got device and is comprised guide portion, transition part, Handheld Division, guide portion one end and transition part one end join, the transition part other end and Handheld Division one end join, the longitudinal central axis line of described guide portion, transition part, Handheld Division is the same straight line, the transition part longitudinal cross-section progressively increases to connecting the Handheld Division end cross-sectional area from connecting the guide portion end, and the transition part surface is provided with the ridge of many projections.
Further, cone is got device and is also comprised clamping part, and clamping part and the Handheld Division other end join, and the longitudinal central axis line of described guide portion, transition part, Handheld Division, clamping part is the same straight line.
The preferred version of Handheld Division comprises that the Handheld Division cross section is hexagon or triangle or pentagon.
Further, the preferred version of guide member is nose cone.
Further, transition part and Handheld Division join for progressive square, join and be progressive cylinder with guide portion, and the transition part surface is provided with four raised ridges, described raised ridges from the Handheld Division to guide portion direction 90 degree that turned clockwise around the axis.
The utility model has the advantage of, when bolt after parent fracture, elder generation's electricity consumption is drilled in the center of bolt broken end and bores a slightly larger in diameter in the aperture of nose cone maximum diameter, cone being got the nose cone of device and the leading portion of transition part raps in the aperture at bolt broken end center again, then get device to cone in the counterclockwise direction and apply tangential force, tangential force passes to the screw rod broken end, makes it to withdraw from from parent along original mouth.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is that screw rod broken end cone is got device master TV structure figure;
Fig. 2 be among Fig. 1 A-A to view.
Fig. 3 be among Fig. 1 B-B to view.
Fig. 4 is the 3-D view that screw rod broken end cone is got device.
The specific embodiment
Shown in Fig. 1,2,3,4, screw rod broken end cone is got device and is comprised guide portion 1, transition part 2, Handheld Division 3, clamping part 4, guide portion 1 one ends and transition part 2 one ends join, transition part 2 other ends and Handheld Division 3 one ends join, the longitudinal central axis line of described guide portion 1, transition part 2, Handheld Division 3 is the same straight line, transition part 2 longitudinal cross-sections progressively increase to connecting Handheld Division 3 end cross-sectional areas from connecting guide portion 1 end, and transition part 2 surfaces are provided with the ridge of many projections;
Clamping part 4 joins with Handheld Division 3 other ends, and the longitudinal central axis line of described guide portion 1, transition part 2, Handheld Division 3, clamping part 4 is the same straight line; Guide portion 1 is nose cone; Transition part 2 and Handheld Division 3 join to joining for progressive square, with guide portion 1 and are progressive cylinder, and transition part 2 surfaces are provided with four raised ridges, described raised ridges from the Handheld Division 3 to guide portion 1 direction 90 degree that turned clockwise around the axis; Clamping part 4 cross sections are that hexagon also can be triangle or pentagon.
Use procedure of the present utility model: when bolt after parent fracture, elder generation's electricity consumption is drilled in the center of bolt broken end and bores a slightly larger in diameter in the aperture of nose cone maximum diameter, cone being got the guide portion 1 of device and the leading portion of transition part 2 raps in the aperture at bolt broken end center again, then get device to cone in the counterclockwise direction and apply tangential force, tangential force passes to the screw rod broken end, makes it to withdraw from from parent along original mouth.
When making screw rod broken end cone and get device, the hardness of selected material must be greater than the hardness of bolt, and present preparation method is to adopt intensity height, good toughness, tool steel that wearability is strong to grind by hand on grinding tool to form.
Guide portion 1 is nose cone, and purpose is to be conducive to allow screw rod broken end cone get the device location, and the leading portion of guiding transition part 2 can enter in the aperture at bolt broken end center smoothly.
Transition part 2 and Handheld Division 3 join to joining for progressive square, with guide portion 1 and are progressive cylinder, transition part 2 surfaces are provided with four raised ridges, described raised ridges from the Handheld Division 3 to guide portion 1 direction around the axis turned clockwise 90 the degree, such design has strengthened the snap-in force that cone is got device and screw rod broken end in the course of work, cone is got between device and the bolt broken end be difficult for slippage, be conducive to apply tangential torsion.
Handheld Division 3, clamping part 4 have prolonged screw rod broken end cone and have got device length, are convenient to hold; Clamping part 4 cross sections are hexagon or triangle or pentagon, can be advantageously used in connecting the multiple force-multiplier tools such as monkey wrench or box spanner.
