Description
Technical field
The utility model belongs to tower crane attachment device accessory technical field more particularly to a kind of derrick crane attachment device
Reinforce strut.
Background technique
Derrick crane be more than unattached height after just must use attachment device tower body is connected with building, such energy
The outstanding height of tower body is reduced, reduces tower body internal force, improves the stability and tower body rigidity of tower crane.After the attachment of derrick crane multiple tracks,
The continuous beam on many supports that mechanics model can simplify as elastic support, topmost the support reaction at one of attachment is maximum for tower body.
Attachment device is generally made of adhesion frame, Anchored Bar, attaching frame and built-in fitting etc., attached at tower body attachment
Frame be connected with tower body main chord, horizontal force and torque are transmitted to building by Anchored Bar.At this point, tower body main chord is born
There is the hidden danger of local buckling due to horizontal force is excessive in corresponding reversed horizontal force, main chord.
General derrick crane adhesion frame is held out against with tower body main chord using independent surrounding or clamping structure, tower body are attached
Place without reinforcing stull or the structure of tower body main chord unstability due to horizontal force can be prevented, or be disposed with reinforcement stull, but it makes
Flexibility is poor, and assembly, disassembly, transport process are inconvenient.
Summary of the invention
Place in order to overcome the above-mentioned deficiencies of the prior art, the utility model provide a kind of derrick crane attachment device and add
Strong strut, the reinforcement strut cooperate attachment device to use, and operation is light, securely and reliably, can effectively prevent the main string of tower body at attachment
Bar unstability due to horizontal force.
To achieve the above objectives, the present invention adopts the following technical solutions: a kind of derrick crane attachment device is reinforced
Strut, including two groups of bodies of rod arrange that the body of rod includes long strut, locking nut, adjusts spiral shell between two groups of bodies of rod in right-angled intersection
Bolt, short strut and anchor ear, the anchor ear include the hoop of two sections of rectangular types, and one end of two sections of hoops is hinged, the other end
It is connected by bolt pair, one end of aforementioned long strut is connect with a hoop, one end of aforementioned short strut and another anchor ear
Body connection, long strut and the opposite endface of short strut are equipped with end plate, are equipped with reversed threaded hole at the center of two end plates,
The aforementioned surface for adjusting bolt is divided into two sections of reversed screw threads, is bolted between long strut and short strut by adjusting, and
Adjust the locking nut there are two setting on bolt with end face cooperation.
In the above-mentioned technical solutions, pass through bolt and split pin connection between the hoop.
In the above-mentioned technical solutions, the locking nut of the endface of the long strut is left-handed locking nut, short strut
The locking nut of endface is dextrorotation locking nut.
In the above-mentioned technical solutions, the length ratio of the short strut and long strut is 1/7 to 1/5.
In the above-mentioned technical solutions, the long strut, short strut and the hoop of its endface pass through welded connecting.
The beneficial effects of the utility model are: the reinforcement strut is reasonable in design and simple, operation is light, safely may be used
It leans on, can effectively prevent tower body main chord unstability due to horizontal force at attachment.
Detailed description of the invention
Fig. 1 uses structural schematic diagram for the utility model.
Fig. 2 is the overlooking structure diagram of the utility model.
Wherein: 1. long struts, 2. left-handed locking nuts, 3. adjust bolt, 4. dextrorotation locking nuts, 5. short struts, 6. spiral shells
Bolt pair, 7. hoops, 8. bolts, 9. split pins, 10. adhesion frames, 11. main chords.
Specific embodiment
With reference to the accompanying drawing and specific embodiment the utility model is described in further detail.
A kind of derrick crane attachment device as depicted in figs. 1 and 2 reinforces strut, including two groups of bodies of rod, two groups of bodies of rod
Between arranged in right-angled intersection, the body of rod includes long strut 1, locking nut, adjusts bolt 3, short strut 5 and anchor ear, the anchor ear
Hoop 7 including two sections of rectangular types, one end of two sections of hoops 7 is hinged, and the other end is connected by bolt pair 6, aforementioned length
One end of strut 1 is connect with a hoop 7, and one end of aforementioned short strut 5 is connect with another hoop 7, long strut 1 and short
The opposite endface of strut 5 is equipped with end plate, and reversed threaded hole is equipped at the center of two end plates, aforementioned adjusting bolt 3
Surface is divided into two sections of reversed screw threads, is connected between long strut 1 and short strut 5 by adjusting bolt 3, and adjusts on bolt 3
If there are two the locking nuts with end face cooperation.
In the above-mentioned technical solutions, it is connected between the hoop 7 by bolt 8 and split pin 9.
In the above-mentioned technical solutions, the locking nut of the endface of the long strut 1 is left-handed locking nut 2, short strut 5
Endface locking nut be dextrorotation locking nut 4.
In the above-mentioned technical solutions, the length ratio of the short strut 5 and long strut 1 is 1/7 to 1/5.Long strut 1 and short support
The length ratio of bar 5 is within the scope of this, is kept the stress for adjusting bolt 3 more reasonable, is prolonged the service life and guarantee safety.
In the above-mentioned technical solutions, the long strut 1, short strut 5 and the hoop 7 of its endface pass through welded connecting.
Using the utility model reinforcement strut when, long strut 1 and short strut 5 are linked together by adjusting bolt 3,
Hung in standard knot after assembling, along standard knot diagonal install, when its both ends fastly close to main chord 11 when, pass through rotation
Bolt 3 is adjusted, so that long strut 1 is withstood main chord 11 with short strut 5, is screwing left-handed locking nut 2 and dextrorotation locking screw respectively
Mother 4, fixes its length；Last clamping screw pair 6, prevents reinforcement strut from sliding downwards and falling accident occurs.Then phase is used
Same step installs another group of body of rod, makes two groups of bodies of rod in distribution up and down, and vertically.
Adhesion frame 10 is attachment device, which is used cooperatively with adhesion frame 10, and effect is more preferable.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in
Change or replacement, should be covered within the scope of the utility model.
