Abstract
The utility model provides a torque wrench accessory used for the torque test of a thread protector; the torque wrench accessory comprises a transferring rod and two clamping jaws which can slide on the transferring rod; fastening bolt holes are arranged on both surfaces of the clamping jaws; a square hole is arranged in the middle part of the transferring rod; calibrations which are symmetrical to the center of the transferring rod are arranged on both sides of the transferring rod; the calibrations are used for indicating the fixing positions of the clamping jaws. The torque wrench accessory has the advantages that the torque wrench accessory can connect the torque wrench with the thread protector conveniently; the torque tests which fulfill the API 5CT requirements are achieved; the accessory is applicable to the situation that the petroleum casing pipe protector is screwed up according to certain torque.
Description
Technical field
The utility model relates to a kind of testing tool, particularly a kind of dial torque wrench annex that is used for the torsional moment test of screw thread protection device.
Background technology
Before the petroleum casing pipe shipping, the screw thread protection device is installed, exempt from transportation and shipment in order to protective casing screw thread and thread end actinal surface and damage.By petroleum casing pipe standard API 5CT requirement; petroleum casing pipe screw thread protection device before use; do torsional moment test, be also included within and do before and after screw thread protection device vibration test, slippage test and the salt spray corrosion test, the moment of torsion when needing test to tighten and dismantle the screw thread protection device.At present, can't buy from the market and be specifically designed to the dial torque wrench of tightening and dismantle the screw thread protection device, the dial torque wrench that can buy uses when only being used to tighten or dismantle common screw, nut, can't be used to tighten and dismantle the screw thread protection device.
Summary of the invention
For solving the problem that exists in the above-mentioned technology, the purpose of this utility model provides a kind of dial torque wrench annex that is used for the torsional moment test of screw thread protection device, and by means of this annex, the screw thread protection device of all size is tightened and dismantled to available common dial torque wrench.
For achieving the above object; technical solution of the present utility model provides a kind of dial torque wrench annex that is used for the torsional moment test of screw thread protection device; wherein: this annex comprises an adapting rod 1 and two jaws 2 that can slide on adapting rod 1; on jaw 2, be provided with fastening screw keyhole 3 and fastening screw keyhole 4; on the middle part of adapting rod 1, be provided with a square hole 5; also be carved with on adapting rod 1 both sides and the centrosymmetric scale 6 of adapting rod, be used to indicate the position location of jaw 2.
Effect of the present utility model is to use this annex quickly and easily dial torque wrench and screw thread protection device to be coupled together, and finishes to meet the torsional moment test that API 5CT requires, or is used for requirement tightens petroleum casing pipe screw thread protection device by certain moment of torsion occasion.If there is not this or similar this fastening means, can't finish the torsional moment test of screw thread protection device.

Embodiment
Reaching embodiment in conjunction with the accompanying drawings is illustrated dial torque wrench accessory structure and the use that is used for the torsional moment test of screw thread protection device of the present utility model.
As shown in Figure 1; the dial torque wrench annex that is used for the torsional moment test of screw thread protection device of the present utility model; this annex comprises an adapting rod 1 and two jaws 2 that can slide on adapting rod 1; be provided with fastening screw keyhole 3 and fastening screw keyhole 4 on jaw 2, fastening screw keyhole 3 is used for by fastening bolt jaw 2 being fastened on the screw thread protection device.Fastening screw keyhole 4 is used for by fastening bolt jaw 2 being fastened on adapting rod 1.On the middle part of adapting rod 1, be provided with a square hole 5, be used for connecting with four angle heads of dial torque wrench.Also be carved with on adapting rod 1 both sides and the centrosymmetric scale 6 of adapting rod, be used to indicate the position location of jaw 2.
When using this dial torque wrench annex; at first two jaws 2 are enclosed within on the adapting rod 1; symmetrical scale 6 according to screw thread protection device diameter and both sides, adapting rod 1 center; position to two jaws 2 is adjusted; screw and be screwed in two fastening bolts in the fastening screw keyhole 3 on the jaw 2; two jaws 2 are fastened on the screw thread protection device; screw again and be screwed in two fastening bolts in the fastening screw keyhole 4 on the jaw 2; two jaws 2 are locked on the adapting rod 1; simultaneously four angle heads on the dial torque wrench are inserted in the square hole 5 of adapting rod, but carry out torsional moment test with regard to the double thread protector.
Dial torque wrench annex of the present utility model is mainly used in the torsional moment test of petroleum casing pipe screw thread protection device, also can be used for requirement tightens petroleum casing pipe screw thread protection device by certain moment of torsion occasion.
