Description
Technical field
The utility model relates to a kind of rotary test chuck.
Background technology
Test chuck is in order to guarantee the servicing unit of oil pumper testing tool operate as normal, to be installed on the oil pumper poliched rod eye, and used test chuck is divided three compositions at present: i.e. base plate, righting rod, footstock; Because structural problem, the side's of loading and unloading clamp when well head work (as bump pump, build the pressure, transfer dead space etc.), hand often neither one is concentrate on work at selected units reliably; Can only grab on the righting rod of test chuck; Because test chuck is split type, hand channel regular meeting is squeezed by chuck and hinders (upper and lower end), not only endangers personal safety; Also can damage instrument, thus improve and innovate imperative.
Summary of the invention
To above-mentioned situation, for overcoming the prior art defective, the purpose of the utility model just provides a kind of rotary test chuck, can effectively solve to use inconvenience the problem of harm personal safety and damage instrument.
The technical scheme that the utility model solves is; Comprise base plate, righting rod and footstock, there is the through hole that is communicated with up and down at the center of footstock, on the through hole inner face internal thread is arranged; External thread is arranged at righting rod top; The upper end spinning of righting rod is in the through hole of footstock, and the lower end of righting rod is contained on the base plate, jug on the base plate.
The utility model is simple in structure, and is easy to process, and cost is low, safe in utilization, reliable, high efficiency.
Description of drawings
Fig. 1 is the structural front view of the utility model.
Embodiment
Elaborate below in conjunction with the embodiment of accompanying drawing to the utility model.
Provided by Fig. 1, the structure of the utility model is to comprise base plate, righting rod and footstock; There is the through hole that is communicated with up and down at the center of footstock 1; On the through hole inner face internal thread is arranged, external thread is arranged at righting rod 2 tops, and the upper end spinning of righting rod is in the through hole of footstock; The lower end of righting rod is contained on the base plate 3, and jug 4 on the base plate.
Described righting rod 2 is the hollow body; There is hole at described base plate 3 centers, are used to assemble righting rod.
The utility model is original three parts to be formed make two parts composition into, and the base plate of prior art, righting rod and footstock are independent separately three parts, and the utility model is that righting rod and footstock are linked together and base plate formation two parts through screw thread (screw thread); Because righting rod and footstock be for being threaded, the height of scalable righting rod is after guaranteeing to test head and loading onto; Can slippage, avoid injuring operating personnel by a crashing object or breaking instrument, and installed handle on the base additional because of head falls; When the people when well head is worked, sufficient assistant space is arranged, although the incident of the side's of having clamp strip takes place; The people also can be in the very first time district out of danger, guarantee personal safety.
The characteristics of the utility model are specific as follows:
1, card is tested the more stable of head card apart from regulating;
2, the bottom installs handle additional, and is easy to operate, safe, reliable;
3, protect the person and equipment to preserve to greatest extent, effectively avoided the generation of security incident, guaranteed personal safety;
4, minimizing stops the well time, shortens the time of well head work (test, transfer dead space, bump pump etc.) greatly,
Increase work efficiency.
