Utility model content
The adverse effect that conllinear does not cause of steel rope up and down existing in vertical adjustment is processed for the coupling running block in above-mentioned existing piling machinery; the utility model provides a kind of coupling running block automatic distance-adjusting mechanism; do not change the integral structure of existing machinery; can be in the situation that upper and lower steel rope produces angle the distance of automatic regulation moving assembly pulley and guide rail, protect running block not damaged.
The utility model adopts following technical scheme to realize: a kind of coupling running block automatic distance-adjusting mechanism, described coupling running block connects fixed pulley by steel rope respectively up and down, the fixed pulley that its below connects is arranged on the platform of an angle adjustable, movable pulley frame is provided with sliding component, described coupling running block is realized location and is slided up and down on the pile frame guide rail vertically arranging by sliding component, between described movable pulley frame and sliding component, by connecting rod, be connected, the two ends of described connecting rod are hinged with described movable pulley frame and sliding component respectively.
Described coupling running block comprises top sheave, lower sheave and the upper and lower pulley yoke being hinged, and described sliding component is arranged on top sheave frame and/or downslide wheel carrier.
Described top sheave is presented lower vertical setting with lower sheave.
Described sliding component is holding claw, is separately positioned on top sheave frame and/or downslide wheel carrier both sides coordinate with pile frame guide rail.
A connecting rod is at least set between described sliding component and movable pulley frame, and two and the long connecting rod such as plural be arranged in parallel.
When terrain slope, the steel rope up and down of coupling running block is not on the same line, by the utility model such scheme, connecting rod rotates around the hinge at its two ends, regulate the vertical distance of coupling running block and guide rail, realize upper and lower steel rope with being in vertical direction, eliminate the horizontal component of force F that conllinear does not produce.
Hence one can see that, adopts coupling running block automatic distance-adjusting mechanism that the utility model relates to can effectively avoid being coupled running block and the horizontal pressurized of pile frame guide rail or tension, improves the reliability of hoisting operation.
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
