Abstract
The utility model discloses a return wheel device used for a rope railway, comprising a base, a hollow shaft, a solid shaft, a return wheel and an end cover, wherein the hollow shaft is arranged on the base; the solid shaft is sheathed in the hollow shaft; the return wheel is rotatablely arranged on the hollow shaft; and the end cover is arranged at the lower end of the hollow shaft, and the end cover is connected with the lower end of the solid shaft. According to the return wheel device used for the rope railway, when in a normal state, the hollow shaft is a working shaft and the solid shaft is a protective shaft. When the hollow shaft is broken owning to fatigue or accident, the solid shaft can effectively bear whole weight of the return wheel, therefore, the accident of the return wheel owning to the fly-out and dropping on the ground can be prevented, thus playing a role in shaft-breaking protection.
Description
Technical field
The utility model relates to a kind of roundabout wheel device, especially relates to a kind of roundabout wheel device cableway, that have the off-axis defencive function that is used for.
Background technology
The transmission shaft of roundabout wheel device of tradition cableway is a single shaft, because the return sheave bearing is subjected to the steel cable pulling force, very easily because of tired or meet with an accidet and rupture, make return sheave fly out or falls earthward and cause the accident.
The off-axis fender guard of tradition cableway is the mode that adopts the outer protection of wheel, promptly on the base of roundabout wheel device or anchor foundation blocking arm is set, and the end of this blocking arm extends inward into the return sheave outer end, return sheave is blocked by blocking arm after it takes turns axle fracture do not come off.But this off-axis protected mode is also unreliable, and at first, owing to there is not other anchor fitting, when return sheave was blocked by blocking arm, the position that will hang with the blocking arm retaining was that rock at the center behind the wheel axle fracture, and protection is unstable, has great accident potential; Secondly, because the total weight of return sheave and associated components thereof will be born by blocking arm behind the drive shafts fracture, so blocking arm very easily damages or comes off, thereby do not have the protective effect of failure-free off-axis.In addition, this response time of taking turns outer protection mode is longer, and after blocking arm is set the volume of driving machine is increased, and required installing space is big, and profile is inharmonious.

The specific embodiment
Describe embodiment of the present utility model below in detail, the example of described embodiment is shown in the drawings, and wherein identical from start to finish or similar label is represented identical or similar elements or the element with identical or similar functions.Below by the embodiment that is described with reference to the drawings is exemplary, only is used to explain the utility model, and can not be interpreted as restriction of the present utility model.
In description of the present utility model, term " on ", close the orientation of indications such as D score, " top ", " end " or position is based on orientation shown in the drawings or position relation, it only is the utility model rather than require the utility model therefore can not be interpreted as for convenience of description with specific orientation structure and operation to restriction of the present utility model.
Below in conjunction with the roundabout wheel device that be used for cableway of accompanying drawing detailed description according to an embodiment of the utility model.
As shown in Figure 1, according to the roundabout wheel device of an embodiment of the present utility model, comprise base 1, hollow shaft 2, solid axle 3, return sheave 4, end cap 5 and pressing plate 6.
The lower end of hollow shaft 2 is fixedly mounted on the base 1.Solid axle 3 is sleeved in the hollow shaft 2, and in an example of the present utility model, the top and bottom of hollow shaft 2 and solid axle 3 are concordant respectively, so that end cap 5 and pressing plate 6 are installed.
Return sheave 4 is rotatably installed on the hollow shaft 2 by bearing, and the following baffle ring 42 that is used for catch bearing is installed on the lower surface of return sheave 4, and also be equipped with on the upper surface of return sheave 4 be used for catch bearing on baffle ring 41.Wherein, be provided with seal ring 43 between baffle ring 42 and the hollow shaft 2 down.
Pressing plate 6 links to each other with the upper end of hollow shaft 2 with solid axle 3 respectively, for example links to each other with the upper end of hollow shaft 2 with solid axle 3 respectively by bolt 62.In addition, on the lower surface of pressing plate 6, also be formed with the flange 61 that is used for encircling in the catch bearing.
By pressing plate 6 is set solid axle 3 is connected with return sheave 4 with hollow shaft 2, and end cap 5 makes solid axle 3 be connected with base 1 with hollow shaft 2, make solid axle 3 when hollow shaft 2 damages, can effectively bear the total weight of return sheave 4 like this, prevent return sheave 4 slippages.
In addition, on pressing plate 6, can also be provided with the driving lever 71 that is used to stir travel switch 7, and travel switch 7 is connected with the control system signal, can reaches the function that monitoring bearing damages.Particularly, when bearing failure and hollow shaft 2 when disconnected, though can not cause return sheave 4 to fly out, bearing failure is very big to the damage of equipment, needs in time to find.Therefore, when the stuck drive hollow shaft 2 of bearing failure rotated, the driving lever 71 that drives on the pressing plate 6 was stirred travel switch 7, and travel switch 7 reaches control system with signal, and then the control cableway quits work.
As shown in Figures 2 and 3, the bottom of base 1 is fixed on the anchor foundation 9.Steel cable 10 is on return sheave 4, and when cableway was worked, steel cable 10 was pulled, and return sheave 4 is rotated, and the transmission shaft of pulling force by return sheave 4 is passed on the anchor foundation 9 through base 1.
Specifically describe off-axis protection process below with reference to Fig. 1-Fig. 3 according to the roundabout wheel device that is used for cableway of an embodiment of the utility model.
When roundabout wheel device was in normal condition, under the steel cable effect, return sheave 4 rotated, and rotate the outer ring that drives bearing, and bearing inner ring is motionless, and promptly hollow shaft 2 maintains static moving.Hollow shaft 2 is a working shaft, and it bears the steel cable pulling force, and pulling force reaches anchor foundation through base again.Solid axle 3 is a prevention shaft, does not stress basically under the normal working.
When hollow shaft 2 fatigues or when anything crops up so after the fracture; because solid axle 3 is connected with return sheave 4 with base 1 with pressing plate 6 by end cap 5 respectively; make solid axle 3 can effectively bear the total weight of return sheave 4, prevent from that return sheave 4 from flying out and falling earthward to cause the accident, thereby play the effect of off-axis protection.
In addition, when bearing failure and hollow shaft 2 when disconnected, the stuck drive hollow shaft 2 of bearing failure rotates, and the driving lever 71 that drives on the pressing plate 6 is stirred travel switch 7, and travel switch 7 reaches control system with signal then, and then the control cableway quits work.
Adopt the twin shaft protection to reach the off-axis defencive function according to roundabout wheel device of the present utility model, novel structure, the device response time is short, protect reliable and stable, good looking appearance.
Although illustrated and described embodiment of the present utility model, those having ordinary skill in the art will appreciate that: can carry out multiple variation, modification, replacement and modification to these embodiment under the situation that does not break away from principle of the present utility model and aim, scope of the present utility model is limited by claim and equivalent thereof.
