Description

Automatic lifting rotation wheels

Technical field

The utility model relates to a kind of wheels, and especially a kind of being applied on the three-dimensional localization car can be made lifting action with load, and can make the automatic lifting rotation wheels of 360 degree rotations.

Background technology

In the man-hour that adds of carrying out this class main equipment of hull, need to utilize and can the three-dimensional localization car that the strong point is adjusted on three dimensions be supported equipment, the function of this three-dimensional localization car has determined that car body needs to make lifting action with respect to wheel, but the wheel of existing three-dimensional localization car can't rotate, therefore when needing the whole direct of travel of adjustment car body, extremely bother, car body need be pulled away from the supported object below, after in a bigger space, adjusting attitude, again it is transported to the bottom of main equipment, this adjustment mode is very loaded down with trivial details, takes time and effort.Therefore need a kind ofly can address the above problem now, can realize that wheel rotates in the scopes of 360 degree, finally reach and adjust wheel or the dependency structure that the direction purpose is advanced by three-dimensional localization garage by simple operations.

Summary of the invention

The utility model is in order to solve the above-mentioned deficiency of existing in prior technology, proposes a kind of simple in structurely, and modern design can be made lifting action with load, and can make the automatic lifting rotation wheels of 360 degree rotations according to actual needs.

Concrete solution of the present utility model is: a kind of automatic lifting rotation wheels, comprise wheel 1, the rotating shaft of wheel 1 is connected with wheels 2, wheels 2 and car body 3 structure that is connected to one, it is characterized in that: be set with axle 4 on the described wheels 2, the bottom slip cap of axle 4 is connected in the bottom bearing 5, and bottom bearing 5 is fixedlyed connected with car body 3; Adjusting nut 6 has been threaded on the axle 4 above the bottom bearing 5, be socketed with spring 7 on the axle 4 of adjusting nut 6 tops, the upper end of spring 7 withstands on the below of the top bearing 8 of fixedlying connected with car body 3 equally, the axle 4 of top bearing 8 tops is socketed among the worm gear 9, and the axle 4 with worm gear 9 between be connected by key, worm screw 10 rotational support that are meshed with worm gear 9 are on car body 3.

The utility model is compared with prior art, has following advantage:

The automatic lifting rotation wheels of this kind of version, it is simple in structure, design ingenious, novel, except possessing, can also pass through shirtsleeve operation along with do the action of vertical lifting with respect to car body car body carrying back, just can realize the action that wheel rotates with respect to ground work 360 degree, be supported on the angle of a plurality of automatic lifting rotation wheels of three-dimensional localization car vehicle body side by adjustment, control the direct of travel of three-dimensional localization car, saved a large amount of work; It is simple in structure simultaneously, easy to make, with low cost, therefore we can say that this automatic lifting rotation wheels have possessed multiple advantage, be particularly suitable for and the supporting use of three-dimensional localization car, be applied in the field that weight supports and three dimensions is regulated in the heavy industry such as boats and ships production, manufacturing, its market prospects are very wide.

Fig. 1 is the structural representation of the utility model embodiment.

The specific embodiment

Below in conjunction with the description of drawings specific embodiment of the present utility model.As shown in Figure 1: a kind of automatic lifting rotation wheels, comprise wheel 1, the rotating shaft of wheel 1 is connected with wheels 2, wheels 2 and car body 3 structure that is connected to one, the upper end of wheels 2 is vertically arranged with axle 4, axle 4 bottom slip cap is connected among the bottom bearing 5, and bottom bearing 5 is bolted to connection with car body 3 and is one; Bottom bearing 5 tops the axle 4 on by the adjusting nut 6 that has been threaded, by the height of adjusting nut 4, the bottom surface of car body 3 and the distance between the ground in the time of can regulating no-load; The axle of adjusting nut 6 tops is socketed with spring 7 on 4, and the top of spring 7 withstands on the below of top bearing 8, and top bearing 8 is equally by bolt and car body 3 structure that is connected to one; The axle of top bearing 8 tops 4 is socketed among the worm gear 9, and axially is provided with key on top bearing 8, and axle 4 and worm gear 9 are connected by key, and the worm screw 10 that has been meshed with worm gear 9, worm screw 10 rotational support are on car body 3.

The course of work of the automatic lifting rotation wheels of the utility model embodiment is as follows: the wheels of this kind version are fixedlyed connected with the car body 3 of three-dimensional localization car, when three-dimensional localization car bearing load, the pressure that car body 3 is born is transmitted on the wheels, spring 7 is compressed, car body 3 moves downward with respect to wheel 1, bottom surface until car body 3 contacts with the bottom surface, structure by three-dimensional localization car itself is carried out adjustment on the three dimensions to the strong point, in this process, spring 7 is in compressed state all the time; After the load on the three-dimensional localization car shed, spring 7 restPosed, and car body 3 disengages with ground;

When needs are adjusted the direct of travel of wheel 1, utilize instrument that worm screw 10 is rotated, worm screw 10 can drive worm gear 9 actions that are meshed with it, and the endoporus of worm gear 9 is connected by key with axle 4, therefore can drive axle 4 and rotate, and all fixedly connected with wheels 2, wheel 1 in the lower end of axle 4, thereby realize the rotation of wheels 2 and wheel 1, by adjusting the rotational angle of a plurality of wheels 1 be connected with three-dimensional localization car car body 3, realize adjusting the purpose of the direct of travel of car body 3; Abundant when the quantity of wheel 1 like this, when the bearing capacity of spring 7 is enough big, can realize that also heavy duty is mobile.
