Description
Technical field
The present invention relates to the hoisting crane technical field, relate in particular to the horizontal guide piece of a kind of hoisting crane.
Background technology
Large span, the hoisting crane that running velocity is high, in actual production, cause wheel and interorbital to produce serious wearing and tearing because a variety of causes hoisting crane there will be the deflection operation, i.e. the so-called rail phenomenon of gnawing.Due to serious wear, some crane wheel workpiece life-spans are some months only, and some steel rail for crane have to change in advance.On the other hand, deflection when operation transmission device need overcome larger resistance, and in design, the load-carrying capacity of transmission device and motor capacity all need corresponding increase, and for this reason, people seek various ways and attempt to overcome and improve above-mentioned phenomenon.
At present, horizontal guide sheave often is installed on crane end carriage, but due to after existing horizontal guide sheave assembles, inconvenience is adjusted in gap between horizontal guide sheave and track, and dismounting is loaded down with trivial details, and adjustment is wasted time and energy, difficulty is larger, along with the wearing and tearing of horizontal guide sheave, distance between the two increases, and causes guiding unfavorable, when after certain degree, just must replace the horizontal guide sheave of wearing and tearing with new horizontal guide sheave, increase maintenance cost, waste time.
Summary of the invention
The object of the present invention is to provide the horizontal guide piece of a kind of hoisting crane, be intended to solve horizontal guide sheave and the adjustment inconvenience of the gap between track of prior art, along with the wearing and tearing of horizontal guide sheave, must replace with new horizontal guide sheave the horizontal guide sheave of wearing and tearing, the technical matters that cost is high.
The present invention realizes like this, the horizontal guide piece of hoisting crane, comprise the erecting frame be fixedly mounted on end carriage, be rotatablely equipped with two turning sets on described erecting frame, between each described turning set and erecting frame, be equipped with for described turning set is fixed in to the locking mechanism on described erecting frame, all be fitted with an eccentric shaft in each described turning set, described eccentric shaft comprises the extension that is installed on the installation portion in described turning set and stretches out described turning set, described installation portion and extension disalignment, described installation portion and turning set are in transmission connection by key, the two ends of described turning set are equipped with jam nut, described jam nut is threaded with described eccentric shaft, described extension is rotatablely equipped with horizontal guide sheave, two described horizontal guide sheaves lay respectively at the both sides of track.
As a kind of improvement, described locking mechanism comprises for the axial limit structure for limiting described turning set longitudinal travel with for limiting the circumferential positioning structure of described turning set rotation.
As improving further, described axial limit structure comprises and is fixedly mounted on the flange of described turning set away from an end of described extension, near described extension one end, spacing ring is installed on described turning set, described spacing ring is set on described turning set, and described spacing ring offsets with the jam nut near described extension one end.
As improving further, described flange and turning set are set to one.
As improving further, described circumferential positioning structure comprises by fastener and is fixedly mounted on the location tooth bar on described erecting frame, and described location tooth bar and flange are connected by meshing transmission.
As improving further, described installation portion is provided with and coordinates the force section in order to the described eccentric shaft of auxiliary rotary with spanner away from an end of described extension.
Owing to adopting technique scheme, the invention has the beneficial effects as follows: owing to being rotatablely equipped with turning set on erecting frame, by locking mechanism, turning set is fixed on erecting frame, be fitted with eccentric shaft in turning set, eccentric shaft and turning set are in transmission connection by key, make eccentric shaft rotate together with turning set, jam nut is established at the turning set two ends, jam nut is threaded with eccentric shaft, by adjusting jam nut to the eccentric shaft axial location, eccentric shaft is limited to suitable level height, simple in structure, easy to adjust, be rotatablely equipped with horizontal guide sheave on extension, two horizontal guide sheaves lay respectively at the both sides of track, pass through eccentric rotation axis, just can adjust the gap between horizontal guide sheave and track, screw jam nut and adjust the level height of horizontal guide sheave, with realistic technical requirements, then regulating locking mechanism locks eccentric shaft, adjust simple and convenient, wearing and tearing with horizontal guide sheave, can further adjust the gap between horizontal guide sheave and track, adjust effective, reduced the replacing of horizontal guide sheave.
Because locking mechanism comprises axial limit structure and circumferential positioning structure, in order to longitudinal travel and the slewing area that limits turning set, and then eccentric shaft is fixed on suitable level height, keep the appropriate clearance between horizontal guide sheave and track, realistic technical requirements.
Because axial limit structure comprises flange and spacing ring, flange is away from extension, spacing ring is near extension, and spacing ring is set on turning set and with the jam nut near extension and offsets, and turning set is fixed on erecting frame, the turning set that prevents from being in course of adjustment is subjected to displacement in the axial direction, flange and spacing ring are set, and simple in structure, axial location is effective, preferred flange and turning set are set to one, easier for installation.
