Detailed description of the invention
embodiment 1:
As depicted in figs. 1 and 2, the utility model provides a kind of pumping top sheave, comprise pulley main body 2, the outside of pulley main body 2 is covered with shell 9, and the pivot shaft 3 of pulley main body 2 is provided with force snesor 4, and force snesor 4 is positioned at shell 9, shell 9 is stretched out at the two ends of pivot shaft 3, two ends of pivot shaft 3 are separately installed with the pressing plate 7 coaxial with pivot shaft 3, and the bottom of shell 9 offers symmetrically arranged steel rope entrance 11 and steel rope outlet 12, and the outside face on shell 9 top is connected with suspension ring 1.
When pulley main body 2 works; by suspension ring 1, top sheave 4 is hung on tractor hoist hook; steel rope enters in shell 9 by steel rope entrance 11; after walking around pulley; pass from steel rope outlet 12, the gravity that steel rope carries is carried on force snesor 4 by pulley main body 2, and is measured by the force snesor 4 at pivot shaft 3 two ends; steel rope drops in shell 9 after rubbing with pulley main body 2 at the upper dirt taken out of in journey that moves past, and is conducive to environmental protection.
It should be noted that, the unsplit casing 9 that pulley main body 2 is installed, the effect of shell 9 is that the dirt brought by steel rope intercepts in shell 9, it is ingenious that structure has design, the cost increased is suitable with the independent tension pick-up purchased, be applicable to batch manufacturing, and shell is installed, and is easy to dismounting and cleaning after greasy dirt gathers simple;
Steel rope moving belt movable pulley main body 2 is rotated, tension force is delivered on pivot shaft 3 simultaneously, the pivot shaft 3 of pulley main body 2 is integrated with force snesor 4, force snesor 4 monitors the change of tension force, and the tension force that force snesor 4 gathers can adopt 4-20mA standard signal to draw by cable or radio to the instrument of measurement.This kind of Structure composing is simple, does not increase new parts.With regard to top sheave structure, identical with the top sheave structure of not integrated force snesor, during work, the same with common top sheave, suspension is arranged on derrick hook, and signal cable directly causes measuring instrument place, just measures by measuring instrument and shows the change of tension force.
