Abstract
The utility model discloses a fixture for demounting and mounting an external screw thread protection cover, comprising a fixed frame, wherein a pawl is fixed to one surface of the fixed frame and a driving connecting piece is fixed to the other surface of the fixed frame. The fixture for demounting and mounting the external screw thread protection cover is high in demounting/mounting speed and capable of saving time and reducing the labor intensity, and also does not damage the thread protection cover so that the thread protection cover can be reused and the loss of the thread protection cover can be reduced.
Description
Technical field
The utility model discloses a kind of jig of demolition, installation pin thread thread protector cover, can carry out demolition, installation to the protective cover of guard circle boom end screw thread, is relevant with the jig of demolition, installation drilling well drilling bar end public screw thread thread protector cover concretely.
Background technology
The two ends of drilling well drilling bar all are shaped on screw thread, and an end is public screw thread, and the other end is female screw thread.In order to prevent that screw thread from reducing the infringement to screw thread in the process of loading-unloading vehicle, transportation, need cover on the screw thread place with the thread protector cover, in order to screw thread is protected; Behind the job site, again the thread protector cover is removed, could drilling rod be linked together and carry out probing work.It is known that to be used to adorn or tear open public screw thread end thread protector cover be with instruments such as traditional spanner, screwdrivers; Thread protector cover with the public screw thread of these conventional tool demolition, installation; Not only speed is slow, dismounting efficient is low, labour intensity is big; And cause the damage of public screw thread thread protector cover easily, and need repurchase new thread protector cover when move drilling rod next time, increase equipment cost.At present, also there is not a kind of special mould clamp that is used for the public screw thread thread protector of demolition, installation drilling well drilling bar cover on the market.
Summary of the invention
The purpose of the utility model provides the jig of the public screw thread thread protector of a kind of demolition, installation cover; Utilize the public screw thread thread protector of the jig demolition, installation cover of the public screw thread thread protector of this demolition, installation cover; Not only demolition, installation speed is fast, save time, reduce labour intensity; And do not damage the thread protector cover, and the thread protector cover can be reused, reduce the loss of thread protector cover.
For the purpose that realizes the utility model has been taked following technical scheme:
Make the jig of the public screw thread thread protector of a kind of demolition, installation cover, the jig of the public screw thread thread protector of this demolition, installation cover comprises fixed mount, is fixed with ratchet in the one side of fixed mount, is fixed with transmission connection piece at the another side of fixed mount.
The characteristics of the utility model be simple in structure, easy to manufacture, cost is low, be easy to promote; When its remarkable advantage is demolition, installation pin thread thread protector cover demolition, installation speed fast, save time, reduce labour intensity, do not damage the thread protector cover, reduce the loss of thread protector cover.
Description of drawings
Technical characterictic below in conjunction with accompanying drawing further explain the utility model:
The structural representation of Fig. 1, an embodiment of the utility model;
The plan structure sketch map of Fig. 2, embodiment Fig. 1.
Among the figure: 1, fixed mount 2, ratchet 3, transmission connection piece
The specific embodiment
Like Fig. 1, shown in Figure 2; Among the figure 1 is the fixed mount of the utility model; One side at fixed mount 1 is fixed with ratchet 2, and the ratchet 2 that the utility model is fixed is 4 ratchets, the one side that is fixed on fixed mount 1 of symmetry; Another side at fixed mount 1 is fixed with transmission connection piece 3, and transmission connection piece 3 can link to each other with outer power.
When tearing or adorning public screw thread thread protector cover open, transmission connection piece 3 is linked to each other with outer power, make ratchet 2 block public screw thread thread protector cover, can easily public screw thread thread protector cover be contained in public screw thread place or it is disassembled.
