Abstract
The invention discloses a kind of cardan wheel, comprise wheel, wheel shaft and wheel carrier, described wheel is fixed on below wheel carrier by wheel shaft, described wheel carrier upper end is provided with bearing seat, bearing is provided with in bearing seat, described wheel carrier is provided with wheel axis adjustment device and first round axial translation track, described axis adjustment device of taking turns is provided with anchor shaft and the second axle displacement track, this cardan wheel can be able to make wheel shaft be positioned at eccentric position and not eccentric position by regulating wheel axis adjustment device, can freely turn in the horizontal direction and walk when being positioned at eccentric position, be positioned at not eccentric position time, wheel is blocked by the brake lever in wheel carrier, can not rotate, now wheel shaft is within the bearing on heart line, strengthen when the bearing capacity of wheel is more eccentric, thus the machinery equipping this cardan wheel avoids bias within its major part rest time causes bearing capacity to decline, also the service life of cardan wheel is extended to a certain extent.
Description
Technical field
The present invention relates to a kind of cardan wheel.
Background technology
cardan wheel and so-called movable castor, its structure tolerable injury level 360 ° rotation, the machinery of equipment cardan wheel can be made to walk to any level direction, what cardan wheel was applied is eccentric center principle, namely wheel rotating shaft departs from the line of centers of wheel carrier bearing, makes wheel turn to arbitrarily, due to such structure, the bias of wheel shaft must cause the bearing capacity of wheel to decline, and this is the ubiquitous problem of current cardan wheel.Particularly portable scaffold under construction, because have personnel at scaffold top-operation, can cause rocking of scaffold, because most of wheel is all designed with eccentric throw, so the safety of the workmen on scaffold can be caused to be affected.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of cardan wheel that can switch wheel shaft position.
In order to solve the problems of the technologies described above, the invention provides a kind of cardan wheel, comprise wheel, wheel shaft and wheel carrier, described wheel is fixed on below wheel carrier by wheel shaft, described wheel carrier upper end is provided with bearing seat, is provided with bearing in bearing seat, and described wheel carrier is provided with wheel axis adjustment device and first round axial translation track, described axis adjustment device of taking turns is provided with anchor shaft and the second axle displacement track, and wheel axis adjustment device is fixed on wheel carrier by anchor shaft.
As a further improvement on the present invention, described axis adjustment device of taking turns is provided with operating handle.
As a further improvement on the present invention, brake lever is provided with in described wheel carrier.
Adopt said structure, its beneficial effect is: described wheel carrier is provided with wheel axis adjustment device and first round axial translation track, wheel axis adjustment device is provided with the second axle displacement track, wheel shaft can be made to be positioned at eccentric position and not eccentric position by regulating wheel axis adjustment device, can freely turn in the horizontal direction and walk when being positioned at eccentric position, be positioned at not eccentric position time, wheel is blocked by the brake lever in wheel carrier, can not rotate, now wheel shaft is within the bearing on heart line, strengthen when the bearing capacity of wheel is more eccentric, thus the machinery equipping this cardan wheel avoids bias within its major part rest time causes bearing capacity to decline, also the service life of cardan wheel is extended to a certain extent.
Accompanying drawing explanation
Fig. 1 is the structural representation of cardan wheel of the present invention.
In figure: 1-wheel, 2-wheel shaft, 3-wheel carrier, 4-bearing seat, 5-bearing, 6-takes turns axis adjustment device, 7-first round axial translation track, 8-anchor shaft, 9-second axle displacement track, 10-operating handle, 11-brake lever.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described in detail.
As shown in Figure 1, a kind of cardan wheel, comprise wheel 1, wheel shaft 2 and wheel carrier 3, described wheel 1 is fixed on below wheel carrier 3 by wheel shaft 2, described wheel carrier 3 upper end is provided with bearing seat 4, bearing 5 is provided with in bearing seat 4, described wheel carrier 3 is provided with wheel axis adjustment device 6 and first round axial translation track 7, described axis adjustment device 6 of taking turns is provided with anchor shaft 8 and the second axle displacement track 9, wheel axis adjustment device 6 is fixed on wheel carrier 3 by anchor shaft 8, described axis adjustment device 6 of taking turns is provided with operating handle 10, is provided with brake lever 11 in described wheel carrier 3.
This cardan wheel can be equipped on to be needed to move freely mechanically, by wheel axis adjustment device 6, cardan wheel is placed in mobile and quiescence, when needing mobile, hold operating handle 10, wheel shaft 2 is pushed to an eccentric side, wheel shaft 2 is simultaneously mobile in first round axial translation track 7 and the second axle displacement track 9, until first round axial translation track 7 and the second axle displacement track 9 overlap, wheel shaft 2 is fixed on eccentric position, wheel 1 can in the horizontal direction in turn to arbitrarily and rotate; During stopping, hold operating handle 10, wheel shaft 2 is pushed back a uninfluenced side, and wheel shaft 2 is simultaneously mobile in first round axial translation track 7 and the second axle displacement track 9, and first round axial translation track 7 and the second axle displacement track 9 stagger gradually, until wheel shaft 2 is positioned on the line of centers of bearing 5, wheel 1 is stuck by the brake lever 11 be provided with in wheel carrier 3 simultaneously, can not rotate, reach quiescence, at this moment wheel shaft 2 is positioned on the line of centers of bearing 5, avoids bias and causes bearing capacity to decline.
Any employing and the similar cardan wheel designed by technical characteristic of the present invention will fall within protection scope of the present invention.
