Technical field
The present invention relates to hoisting crane technical field, particularly relate to a kind of hoisting crane horizontally-guided device.
Background technology
The hoisting crane that large span, running velocity are high, in actual production, runs cause wheel and interorbital to produce serious wearing and tearing because a variety of causes hoisting crane there will be deflection, namely so-calledly gnaw rail phenomenon.Due to serious wear, some crane wheel workpiece life-span only some months, some steel rail for crane have to change in advance.On the other hand, when deflection is run, transmission device need overcome larger resistance, and the load-carrying capacity of transmission device and motor capacity all need corresponding increase in the design, and for this reason, people seek various way and attempt to overcome and improve above-mentioned phenomenon.
At present, often on crane end carriage, horizontal guide sheave is installed, but due to after existing horizontal guide sheave assembles, gap adjustment inconvenience between horizontal guide sheave and track, 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 a kind of hoisting crane horizontally-guided device, be intended to the gap solved between the horizontal guide sheave of prior art and track and adjust inconvenience, along with the wearing and tearing of horizontal guide sheave, the horizontal guide sheave of wearing and tearing must be replaced with new horizontal guide sheave, the technical matters that cost is high.
The present invention realizes like this, hoisting crane horizontally-guided device, comprise the erecting frame be fixedly mounted on end carriage, described erecting frame is rotatablely equipped with two turning sets, the locking mechanism for being fixed on by described turning set on described erecting frame is equipped with between each described turning set and erecting frame, an eccentric shaft is all fitted with in each described turning set, described eccentric shaft comprises the installation portion be installed in described turning set and the extension stretching 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, horizontal guide sheave described in two lays respectively at the both sides of track.
Improve as one, described locking mechanism comprises for the axial limit structure for limiting described turning set longitudinal travel with for limiting the circumferential positioning structure that described turning set rotates.
As improving further, described axial limit structure comprises and is fixedly mounted on the flange of described turning set away from one end of described extension, described turning set is provided with spacing ring near described extension one end, 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 the location tooth bar be fixedly mounted on by fastener 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 the force section coordinated with spanner in order to eccentric shaft described in auxiliary rotary away from one end of described extension.
Owing to adopting technique scheme, the invention has the beneficial effects as follows: due to erecting frame being rotatablely equipped with turning set, by locking mechanism, turning set is fixed on erecting frame, eccentric shaft is fitted with in turning set, eccentric shaft and turning set are in transmission connection by key, eccentric shaft is rotated together with turning set, jam nut is established at turning set two ends, jam nut is threaded with eccentric shaft, by adjustment jam nut to eccentric shaft axial location, eccentric shaft is limited to suitable level height, structure is simple, easy to adjust, extension is rotatablely equipped with horizontal guide sheave, 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 the level height of jam nut adjustment horizontal guide sheave, with realistic technical requirements, then locking mechanism is regulated to be locked by eccentric shaft, adjust simple and convenient, with the wearing and tearing of horizontal guide sheave, the gap between horizontal guide sheave and track can be adjusted further, Adjustment effect is good, decrease the replacing of horizontal guide sheave.
Because locking mechanism comprises axial limit structure and circumferential positioning structure, in order to limit longitudinal travel and the slewing area of turning set, and then eccentric shaft is fixed in 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 to be set on turning set and to offset with the jam nut near extension, is fixed on by turning set on erecting frame, the turning set that prevents from being in course of adjustment is subjected to displacement in the axial direction, arrange flange and spacing ring, structure is simple, and axial location is effective, preferred flange and turning set are set to one, easier for installation.
Because circumferential positioning structure comprises location tooth bar, location tooth bar is fixedly mounted on erecting frame by fastener, when eccentric shaft turns is to correct position, regulate location tooth bar to make it engage with flange, eccentric shaft is fixed in the circumferential, and structure is simple, easy to operate, good positioning effect.
Because the instruments such as installation portion is provided with force section, spanner easy to use are with eccentric rotation axis, regulate the gap between horizontal guide sheave and track, make adjustment convenient.
