Background
In the building installation engineering, many kinds of hoisting machinery capable of simultaneously completing vertical lifting and horizontal moving of a heavy object are available, wherein tower cranes are widely applied, and become indispensable main construction machinery in mechanization and equipment of modern high-rise industry and civil buildings. However, the collapse accident of the tower crane in the construction site happens occasionally, the later fruit is often disastrous, and at present, most of the crane jib joints of the tower crane are connected by adopting a half-split pin shaft and are fixed by a triangular baffle and a split pin. The disadvantages of this approach are: in the use process of the tower crane, the triangular baffle is easily ejected out by the semi-open type pin shaft to cause the jib connecting chord pin to fall off, and at the moment, the jib bears huge lateral force instantly, so that the jib is easily broken to cause the collapse of the tower crane.
SUMMERY OF THE UTILITY MODEL
In order to solve the above-mentioned problem that prior art exists, the utility model provides a tower crane jib loading boom chord pin anticreep device, the tower crane of avoiding that can be fine is in the use, and half open type round pin axle is ejecting with the triangle-shaped baffle and is caused the danger that the tower crane jib loading boom drops, through adjustment accommodate the lead screw, can fine match multiple specification and dimension tower crane moreover, can accomplish safe and reliable and the tight triangle-shaped baffle in efficient top, fixed connection round pin axle under various operating modes.
The technical scheme of the utility model as follows:
the utility model provides a tower crane jib loading boom chord pin anticreep device, includes two anticreep steel pipes, two anticreep steel pipe one end is equipped with triangle-shaped baffle and inlays mouthful, two one of anticreep steel pipe is close to triangle-shaped baffle and inlays mouthful serves and be equipped with the opening pinhole, two the one end that triangle-shaped baffle inlays mouthful is kept away from to the anticreep steel pipe is connected with accommodate the lead screw.
The anti-falling steel pipe is connected with the adjusting screw rod through the screw rod connector.
The adjusting screw rod is characterized in that adjusting threads in opposite rotating directions are respectively arranged at two ends of the adjusting screw rod, and a screw rod adjusting hole is formed in the middle of the adjusting screw rod.
The utility model discloses following beneficial effect has:
1. the utility model relates to a tower crane boom chord pin anti-drop device, which can well match tower cranes with various specifications and sizes by adjusting the adjusting screw rod, and can safely and reliably jack the triangular baffle plate and fixedly connect the pin shaft with high efficiency under various working conditions; the danger that a tower crane boom falls off due to the fact that the triangular baffle is ejected out by the semi-open type pin shaft in the use process of the tower crane can be well avoided.
2. The utility model relates to a tower crane jib loading boom chord pin anticreep device should be through anticreep steel pipe top swizzle axle and baffle, even be a whole with the tower crane jib loading boom after penetrating the split pin, the effect of load when can playing the operation of equipartition jib loading boom to the effect of guarantee round pin hub connection fastening, satisfied user demand that can be fine.
3. The utility model relates to a tower crane jib loading boom chord pin anticreep device through be assembled between/be connected between, need not the scene and welds, requires lowly to the operation environment, and is low to site operation personnel's operating skill and quality dependence, is convenient for inspect and monitor in the high altitude.
