Description
Technical field
The utility model belongs to the device used in commercial advertising, displaying, mark etc., and in particular to a kind of heavy rotating
Device.
Background technique
Current many companies generally can indicate the billboard or mark tower of Business Name in its roof installing of handling official business.Our company
The mark tower (application number CN201520216391.0) that a ground uses was devised in 2015, since it is shaft underneath type
Driving and shaft are assemblied on frame, shaft is elongated thick-wall hollow rotating member, and the tower body section of mark is triangle in addition,
It is affected by the wind interference rotation, is not appropriate for the high roof of wind-force is big, wind speed is high ten multilayers, often three months or so shafts go out
It is now bent, the bearing of shaft the top has apparent deformation.3 meters of height of mark tower, in addition shaft gross weight reaches 800kg, if shaft mistake
Short support strength necessarily declines, and is easy to happen mark tower collapse accident.Decelerating motor directly drives shaft, and torque is necessary when starting
In 1000kg or more, cost is too high, be easy to cause motor load is excessive the bad phenomenons, very influence motor longevity such as to occur overheating
Life.
Summary of the invention
To solve the above-mentioned problems, the utility model provides a kind of heavy rotating device, and stability of rotation, wind resistance are good
It is good, it processes, is easy for installation.
A kind of heavy rotating device is stated in bracket and is pacified vertically including rotatable tower body and the bracket for being used to support tower body
Equipped with lower rotary shaft and upper shaft, under the upper end connection tower body of the upper shaft, lower end are sloping shaft tail and are connected by universal joint
Shaft, the lower end of the lower rotary shaft is located at pedestal, upper end is inclination spindle nose to cooperate with universal joint, and the pedestal is installed in bracket
Bottom, axis where the connecting shaft of the universal joint and upper lower rotary shaft and vertical direction are in being obliquely installed for 45 ° of angles, and described ten thousand
Telescopic oil cylinder is connected on the left of to section to drive universal joint swing rotary, the oil cylinder is located on pedestal vertically.
The extension end of the oil cylinder is equipped with connecting rod, the upper end and universal joint articulated, lower end and oil cylinder extension end of the connecting rod
Hingedly.
The extension end of the oil cylinder is equipped with fixing sleeve.
The tower body arc-shaped, central hollow structure positive tetrahedron for surface, the outermost layer of the tower body are equipped with display
Screen.
The utility model has the following beneficial effects: the heavy rotating device oil cylinder is realized in the universal joint of side drive incline
The rotation of upper shaft, for staring torque convenient for control, starting is very steady and is suitable for the environment of this large driving force.Shaft is set
It is set to two sections form, greatly facilitates processing, installation and maintenance.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment；
Fig. 2 is the transmission principle schematic diagram of the utility model embodiment；
Fig. 3 is the tower body schematic cross-section of the utility model embodiment.
In figure: 1 being tower body, 2 be bracket, 3 be pedestal, 4 be lower rotary shaft, 5 be upper shaft, 6 be oil cylinder, 7 be universal joint, 8
It is fixing sleeve for connecting rod, 9,11 is display screen.
Specific embodiment
The utility model is further explained with reference to the accompanying drawing.
The present embodiment is a kind of heavy rotating device, including rotatable tower body 1 and the bracket 2 for being used to support tower body 1, is stated
It is vertically-mounted in bracket 2 to have a lower rotary shaft 4 and upper shaft 5, the upper end connection tower body 1 of the upper shaft 5, lower end be sloping shaft tail and
Lower rotary shaft 4 is connected by universal joint 7, the lower end of the lower rotary shaft 4 is located at pedestal 3, upper end is inclination spindle nose to match with universal joint 7
It closes, the pedestal 3 is installed in 2 bottom of bracket, the universal joint 7 and axis where the connecting shaft of upper lower rotary shaft 5,4 and vertical side
To being in being obliquely installed for 45 ° of angles, the left side of the universal joint 7 is connected with telescopic oil cylinder 6 to drive universal joint 7 to swing rotation
Turn, the oil cylinder 6 is set on the base 3 vertically.Upper lower rotary shaft 5,4 is all made of 45# steel modifier treatment, is fixed with tree-pointb earing, in
Between bearing be fixed on bracket 2 with flanged joint and the centre of location, bearing block is thickeied, bracket 2 welded with 16# I-steel and
At structure welding must be secured.
The extension end of the oil cylinder 6 is equipped with connecting rod 8, and the upper end of the connecting rod 8 and universal joint 7 are hingedly, lower end and oil cylinder 6 stretch
Outlet is hinged.With reference to Fig. 2, tie point motion profile when universal joint 7 rotates on the left of it can not be total with the telescopic direction of oil cylinder 6
Line can adapt to the motion profile of universal joint 7 by hinged connecting rod 8, greatly improve the stability of rotation of lower rotary shaft 5,4
Property.
The extension end of the oil cylinder 6 is equipped with fixing sleeve 9, to oil cylinder 6 and the flexible guiding of connecting rod 8, dustproof and waterproof.
The tower body 1 arc-shaped, central hollow structure positive tetrahedron for surface, the outermost layer of the tower body 1 are equipped with aobvious
Display screen 11.It avoids tower body 1 from bearing too big wind-force effect, reduces the rotation to upper lower rotary shaft 5,4 and interfere, improve each bearing etc.
The service life of components.
