Description
Technical field
The utility model is related to crane support member field, more particularly to a kind of prestressing force tower crane attachment.
Background technology
It is accomplished by that attachment is installed after tower crane is higher than certain height, the purpose of tower crane attachment is exactly by tower crane and building
Thing links together, so that prevent tower crane from bending and the danger toppled occurring because of strong wind or overload, it is traditional in the market
Tower crane attachment be all preventative, can just be worked after tower crane is rocked.
Most existing traditional standard section of tower crane is all bolt connection, and bolted advantage is convenient dismounting, installation side
Just, can repeatedly it utilize, but its shortcoming is also clearly, and bolt easily loosens, and shearing resistance effect is bad, and tower crane is rocked and is easy to draw
The loosening of bolt is played, rocking, which occurs, in tower crane top especially drivers' cab causes unstable, adds the sense of insecurity of tower crane driver, especially
It is particularly hazardous in overload operation, and the swing rocked with weight by a small margin reaches during peak swing have very much in the same direction
May occur accident, cause casualties, trigger dangerous, at the same tower crane often rock can cause bolt used in connection or its
The connection of its some connector does not come off easily closely, or even the danger being broken occurs due to the effect of shearing, safety
Property is poor, and the life-span of bolt or connector also reduces significantly.The tower crane that bolt mode is attached is used for current standard knot, is needed
Hand inspection is often carried out, people need each layer for climbing to tower crane to check in turn when checking, very inconvenient, time-consuming to take
Power.
Utility model content
For above-mentioned deficiency, the utility model provides a kind of prestressing force tower crane attachment, by the tower body for giving tower crane in advance
Applying prestressing force makes it be inclined to building, solves the problem of bolted tower crane is often rocked, eliminates potential safety hazard, together
When add the service life of bolt, solve problem present in background technology.
The utility model is realized by following technology：A kind of prestressing force tower crane attachment, including pull bar, cross bar, support
Bar, push rod, adjusting screw rod, stage clip and built-in fitting, pull bar is with cross bar by hinge, and pull bar is provided with two support bars, two
The length of individual support bar differs, and its length is adjusted according to the gradient of pull bar, and support bar one end is connected other end top with pull bar
On standard section of tower crane, adjusting screw rod and push rod are attached with the built-in fitting on building respectively, and its connected mode is removable
Weld some stage clips, one end welding stage clip of push rod in the connection unloaded, the adjustable height of adjusting screw rod, cross bar side.
Further, the otic placode being connected with pull bar is respectively welded in the cross bar two ends.
Further, the pull bar two ends are provided with the pin shaft hole being connected with cross bar upper ear plate.
Further, do not contacted between the push rod compression spring and standard section of tower crane, and standoff distance is less than 10cm.Work as tower
Hang out it is existing to building direction significantly rock when, push rod and stage clip slowly the direction opposite to tower crane application can ensure tower crane
The inclination of tower body is not in bending or the danger toppled.
The utility model is compared with prior art：
The utility model has the advantage of reduce the height of adjusting screw rod, applied by pull bar, cross bar and stage clip to tower crane
One power to building direction, so that the situation that tower body occurs vibrating or rocked when preventing big wind tower crane, is effectively prevented
Often there is the situation rocked and loosened due to tower crane in bolt, eliminates potential safety hazard, while also considerably increasing bolt
Service life, saves the work for needing often to check bolt, and tower crane driver also more haves a sense of security when drivers' cab works,
The attachment is worthy to be popularized.
Brief description of the drawings
Fig. 1 is the utility model structural representation；
Fig. 2 is the structural representation of cross bar.
In figure, 1, pull bar, 2, cross bar, 21, otic placode, 3, support bar, 4, push rod, 5, adjusting screw rod, 6, stage clip, 7, pre-buried
Part, 8, standard knot, 9, building.
Embodiment
Further illustrate that the present embodiment is, it is necessary to which explanation is to the utility model with embodiment below in conjunction with the accompanying drawings
Descriptive, it is not limited, it is impossible to thus limit protection domain of the present utility model.
As shown in Figure 1-2
A kind of prestressing force tower crane attachment that the utility model is used, including pull bar 1, cross bar 2, support bar 3, push rod 4, regulation
Screw rod 5, stage clip 6 and built-in fitting 7, pull bar and cross bar by hinge, pull bar provided with two support bars, two support bars
Length differs, and its length is adjusted according to the gradient of pull bar, and support bar one end other end that is connected with pull bar withstands on tower crane standard
On section 8, adjusting screw rod and push rod are attached with the built-in fitting on building 9 respectively, and its connected mode is dismountable connection,
Two stage clips are welded in the adjustable height of adjusting screw rod, cross bar side, and stage clip position is corresponding with the main limb of tower-body standard section, push rod
Weld stage clip in one end.
It is preferred that, the otic placode 21 being connected with pull bar is respectively welded in cross bar two ends.
It is preferred that, pull bar two ends are provided with the pin shaft hole being connected with cross bar upper ear plate.
It is preferred that, do not contacted between push rod compression spring and standard section of tower crane, and standoff distance is less than 10cm, its spacing distance
Can be according to the setting height(from bottom) of tower crane attachment and tower crane model is micro- adjusts.When significantly rocking to building direction occurs in tower crane
When, push rod and stage clip slowly the inclination of the direction opposite to tower crane application to ensure tower crane tower body can be not in bending or topple
Danger.
The stage clip also can select other flexible materials, be to prevent from adding tower crane suddenly from elastomeric material
Power, causes rigid damage.
Applying prestressed process is：When mounted, reduce the height of adjusting screw rod, given by pull bar, cross bar and stage clip
Tower crane applies the power to building direction, and the size of the power, which is not to be exceeded, makes the profile of tower crane tower body deformation occur.
It should be pointed out that for those skilled in the art, before the utility model principle is not departed from
Put, some improvement can also be made, these improvement also should be regarded as protection domain of the present utility model；It is unknown in present embodiment
True each part can use prior art to be realized.
