The utility model proposes a kind of derrick crane balance maintain device.
As shown in figure 1, in one embodiment, the derrick crane includes tower body 10 and located at the top of tower body 10
Cantilever 20, the balance maintains device to include the runner 30 located at tower body 10, and the runner 30 is rotatably sheathed on the tower
On body 10, the runner 30 is connected with drive device, and is rotated under the drive of drive device, and the runner 30 is provided with counterweight
Block 40.
As shown in figure 1, in the technical scheme of the present embodiment, runner 30, the runner 30 and driving are provided with tower body 10
Device is connected so that runner 30 is rotated under drive device.When cantilever 20 rotates, can produce an axis using tower body 10 as
In first moment of torsion of axle, the technical scheme of the present embodiment, drive runner 30 to reversely rotate by drive device, form one and the
The second opposite moment of torsion of one torque direction, to balance the influence that the first moment of torsion is produced to tower body 10, makes whole derrick crane
Entirety maintains the state of a relative equilibrium, to reduce the possibility damaged to it.
The calculation formula of moment of torsion is:T=J* α, wherein T are moment of torsion, and unit is Nm (ox rice), and J is rotary inertia, unit
For Kgm2(kilogram square metre), α is angular speed, and unit is Radian per second.In order to what is produced in the rotary course of balanced cantilever 20
Moment of torsion, the moment of torsion produced by runner 30 should be equal in magnitude in opposite direction with its, therefore, is calculating the rotary inertia of cantilever 20
After the rotary inertia of runner 30, it is only necessary to which control that runner 30 and cantilever 20 rotate is in opposite direction, and the angle that runner 30 rotates
The ratio between angular speed that speed and cantilever 20 rotate can be played in the rotary course of balanced cantilever 20 for the inverse ratio of its rotary inertia and produced
Raw torque.
Second embodiment of the present utility model and 3rd embodiment are proposed below based on above-described embodiment.
In the technical scheme of second embodiment realized based on machine driving, be comparatively more applicable for highly relatively low
Derrick crane.
In some embodiments of the embodiment, the drive device include drive link and with the drive link phase
Planetary reduction gear even, the first end of the drive link is connected with the power set for stating cantilever 20, the second end and the row
The outer tooth disk of star decelerator is connected, and the sun gear of the planetary reduction gear is connected with the runner 30 so that the runner 30 and
The cantilever 20 is rotated backward.The runner 30 is fixed in the rotating shaft of the sun gear.
In the technical scheme of the present embodiment, the concrete structure of the planetary reduction gear in the present embodiment refers to prior art
Planetary reduction gear.In specific setting up procedure, the rotary inertia of cantilever 20 and runner 30 is first calculated, then according to its rotary inertia
Ratio setting sun gear and outer tooth disk diameter ratio,
The power set of cantilever 20 synchronous can drive drive rod rotation, drive link passes through band when driving cantilever 20 to rotate
Dynamic outer tooth disk is rotated, and is further driven to sun gear rotation.Because outer tooth disk and sun gear have identical line in rotation process
Speed, and the diameter of sun gear is less than outer tooth disk, so the angular speed of sun gear will be greater than outer tooth disk, so that what runner 30 was rotated
Angular speed will also be improved, simultaneously as by planet gear transmission between sun gear and outer tooth disk, also causing sun gear and outer
The rotation of fluted disc is reversely on the contrary, the runner 30 for being produces the torque opposite with cantilever 20.The technical scheme of the present embodiment can have
The rotary inertia of the balanced cantilever 20 of effect, but having a disadvantage in that can not be introduced into the quality of the article of lifting in rotational speed regulation.
The third embodiment of the present invention is to rely on Electronic Control to realize, the drive device includes motor and control mould
Block, the runner 30 is rotated under the drive of the motor, the control module respectively with the motor and the cantilever
20 controller is connected, and the control module is used to control the motor to rotate backward with the cantilever 20.
In the present embodiment, the control information of the controller of cantilever 20 is obtained using control module, and after result is calculated
With reference to the control thinking in above-mentioned first embodiment, the rotating speed and rotation direction of runner 30 are adjusted by controlling motor.
In some embodiments, the present embodiment further increases sensor to obtain the matter of sling article
Measure, and be turned inertia and be also introduced into calculating, relative to above-mentioned mechanical transmission structure, can more accurately balance tower
The stressing conditions of heavy-duty machine.
It is preferred that, the balancing weight 40 is detachably secured on the runner 30, and the quantity of the balancing weight 40 is many
Individual, multiple balancing weights 40 are angularly uniformly arranged on the runner 30.
As shown in Figure 2, it should be appreciated that in actual use, to the regulation of drive device, such as planetary reduction gear
Although the setting of device or the setting of control program, which rely on known technology, to be realized, it is contemplated that in construction site, and
Non- technical staff all the time with the presence of this area, therefore the balancing weight 40 of activity is further provided with the present embodiment.Specifically make
During, use information table can be worked out according to parameters such as model, the sizes of cantilever 20, and specifically write required under different condition exactly
The quantity of balancing weight 40 to be mounted changes the rotary inertia of runner 30, and adapts to different by adjusting the rotary inertia of runner 30
Service condition.Relative to previous embodiment, operation difficulty is lower, is more suitable for promoting the use of.It should be noted that the present embodiment
In balancing weight 40 should angularly be uniformly arranged when mounted, such as if 3 balancing weights 40, then each two balancing weight 40
Between angle should be 120 degree, if there is provided four, the angle between each two balancing weight 40 should be 90 degree.Can
To ensure the stability of rotary course.
