Abstract
The utility model discloses a sling used for a concrete box girder, which comprises a movable pulley block assembly and a sling assembly, wherein the movable pulley block assembly is articulated with the sling assembly. According to the sling used for the concrete box girder, the sling is designed into a double-layer structure being composed of the movable pulley block assembly and the sling assembly, and a mode of hinge joint is adopted by the double layers; when a girder elevator cannot operate synchronously to lead to the position deviation of a girder lifting trolley, the upper layer and the lower layer of the sling assembly rotate relatively, thereby avoiding the torsion of the concrete box girder and guaranteeing the security of lifting a girder.
Description
Technical field
The utility model relates to the lifting machine technical field, particularly relates to a kind of suspender that is used for concrete box girder.
Background technology
At beam making field, along with the continuous increase of concrete box beam length and deadweight, adopt the separate unit lifting beam machine to lift fortune, it is very big that it vertically reaches horizontal span, and this just causes the horizontal door frame of lifting beam machine and girder very big, has greatly increased deadweight, and then has improved manufacturing cost; So the normal mode that adopts two lifting beam machines to lift fortune is lifted fortune; That is: two rubber-tyred lifting beam machines of the normal employing of large-tonnage concrete box girder are lifted the mode of fortune; Every lifting beam machine disposes identical hanging beam cart system, accomplish from template bale handle, in carrying and to the function of beam transportation vehicle dress beam.Lift the fortune concrete box girder when traversing at lifting beam machine, if the operation of two lifting beam machines is asynchronous, then two hanging beam dolly positions can produce deviation.
The suspender of hanging beam dolly adopts single layer structure in the prior art, and running block beam, suspender beam connect through bolt or welding manner, are the structure that is rigidly connected.Therefore, lift the fortune concrete box girder when lifting beam machine and carry out when traversing,, cause hanging beam dolly position deviation, concrete box girder is reversed if operation is asynchronous; And then causing the distortion of suspender suspension rod, steel rope produces deflection.Not only influence the life-span of suspension rod and steel rope; If reverse severity, possibly cause safety misadventure.
The utility model content
The order of the utility model provides a kind of suspender that is used for concrete box girder, to solve owing to the asynchronous problem that causes the distortion of suspender suspension rod of two lifting beam machines operation.
For the technical scheme of the utility model that achieves the above object provides a kind of suspender that is used for concrete box girder, this suspender comprises running block assembly and lifting assembly, and wherein, said running block assembly and lifting assembly are articulated and connected.
Wherein, said running block assembly comprises running block, running block longeron and running block crossbeam; Wherein, said running block is installed on the running block longeron; Said running block longeron is installed on the running block crossbeam.
Wherein, said lifting assembly comprises suspender beam, equalizing bar, Lian Liang, arm and suspension rod assembly; Said suspension rod assembly is installed on the said arm; Said arm is installed in said the company on the beam; The said beam that connects is installed on the said equalizing bar; Said equalizing bar is installed on the said suspender beam; Said suspender beam and running block crossbeam are articulated and connected.
Technique scheme has following advantage:
The utility model is through being designed to suspender running block assembly and lifting assembly double-decker; And adopt the mode that is articulated and connected between the double-decker; Asynchronous when the lifting beam machine operation, when causing hanging beam dolly position deviation, lifting assembly is two-layer producing relative rotation up and down; Effectively prevent reversing of concrete box girder, guaranteed the safety of bale handle.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is described in further detail.Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model.
Shown in Fig. 1～8, the utility model embodiment relates to a kind of suspender that is used for concrete box girder, and this suspender comprises running block assembly 2 and lifting assembly 3, and wherein, running block assembly 2 is articulated and connected with lifting assembly 3.Running block assembly 2 is installed on the lifting beam machine through the fixed pulley group 1 that is provided with on the lifting beam machine.
Running block assembly 2 comprises running block 4, running block longeron 5 and running block crossbeam 6, and wherein, running block 4 is installed on the running block longeron 5, and running block longeron 5 is installed on the running block crossbeam 6.
Lifting assembly 3 comprises suspender beam 7, equalizing bar 8, Lian Liang 9, arm 10 and suspension rod assembly 11.Suspension rod assembly 11 is installed on the arm 10, and arm 10 is installed on the Lian Liang 9, and Lian Liang 9 is installed on the equalizing bar 8, and equalizing bar 8 is installed on the suspender beam 7.Suspender beam 7 is articulated and connected with running block crossbeam 6.
The utility model decomposes the integral structure of suspender in the prior art, adopts double deck hinged connection mode, and the realization suspender is followed concrete box girder and reversed, and dissolves the case beam and reverses the harmful effect that suspender is produced.
The suspender of the prevented concrete box torsion beam suspension that the utility model provides, it adopts double-decker, and the upper strata is a suspender beam 7, and lower floor is a running block beam 6, and the two connects through articulated manner.When two lifting beam machines move asynchronous; When causing hanging beam dolly position deviation, concrete box girder reverses, but is articulated and connected with adopting between the running block crossbeam 6 because of suspender beam 7; Suspender beam 7 will reverse in company with concrete box girder, and promptly suspender beam 7 rotates relative running block crossbeam 6.This efficiently solves beams of concrete impact to suspension rod when reversing; Running block beam horizontal 6 keeps static relatively simultaneously, has effectively prevented the deflection of steel rope, has improved whole safety of lifting the traversing walking of fortune concrete box girder.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
