Abstract
The utility model relates to a tuyere middle sleeve pull rod. The tuyere middle sleeve pull rod comprises pull rods, wherein the pull rods are two double-arm parallel pull rods, the front ends of the double-arm parallel pull rods are provided with hooks, and fastening bolts are arranged at tail ends of the two pull rods to adjust the opening degrees of the hooks at the front ends. By adoption of the tuyere middle sleeve pull rod, the disassembling time is saved, namely that the original time of 40 minutes required for disassembling one middle sleeve is shortened to be about 10 minutes; the phenomenon of pull rod slipping is reduced, and potential safety hazards are reduced at the same time; and damping down caused by middle sleeve failure is shortened, the time wasted by damping down is reduced, and the production efficiency is improved.
Description
Technical field
The utility model relates to air port, a kind of stokehold service kit, specifically a kind of tuyere medium sleeve pull bar.
Background technology
The stokehold tuyere medium sleeve is changed after breaking down, and does not have in the past special tool, can only be by little cover pull bar, change one in cover need 40 minutes, and use little cover pull bar not skid to occurring easily because of size, affect the replacing time.
The utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, provides a kind of and can be convenient for changing the instrument that overlaps in the sealing, has the characteristics simple to operate that save time.
In order to solve above technical problem, the utility model provides a kind of tuyere medium sleeve pull bar, comprise pull bar, described pull bar is the both arms parallel draw bar that two pull bars consist of, the front end of described both arms parallel draw bar has hook, holding bolt is installed in order to adjust the opening and closing degree of front end hook at two pull bars ends.
The technical scheme that the utility model further limits is: aforesaid tuyere medium sleeve pull bar, the hook direction of the front end of described both arms parallel draw bar are served as reasons, and introversion is outer digs.
The beneficial effects of the utility model are: adopt the utility model to have saved the take-down time, being merely hit to overlap by original dismounting one needed about 40 minutes shorten to about 10 minutes; And reduced the phenomenon of pull bar slippage, also reduced the appearance of potential safety hazard simultaneously; Shortened because of in the damping down that causes of set of fault, reduced damping down and mistaken, enhance productivity.
