Abstract
The utility model relates to bridge building, in particular to a drive device of strand tensioning screws, which comprises a motor and a pair of tensioning screws which are arranged oppositely, wherein an output shaft of the motor is connected with a long shaft. The drive device further includes a pair of driving wheels which are disposed on the long shaft at intervals and driven by the motor. The tensioning screws are driven to be connected through a conveyor belt and the driving wheels. The drive device of strand tensioning screws can realize in and out movement of tensioning screws through a mechanical device.
Description
Technical field
The utility model relates to bridge construction, relates in particular to a kind of strand tensioning screw rod regulating device.
Background technique
Strand is the requisite constituent element of bridge construction, along with the bridge construction continuous advancement in technology, strand also proposed the requirements at the higher level of wind resistance, rain-proof.Because the increasing kind of strand specification is more and more, and the strand productivity is also had higher requirement.In traditional production process, the strand tensioning equipment in use, jacking of tensioning screw rod nut or contraction need to rely on manpower to operate and finish.Very big dangerous of existence not only arranged but also wasted manpower utilization rate efficient very low.
Summary of the invention
The purpose of this utility model is to overcome the above the deficiencies in the prior art part that proposes, and a kind of transmission device of strand tensioning screw rod is provided.The utility model can be realized the turnover action of tensioning screw rod by mechanical device.
To achieve these goals, the utility model adopts following technological scheme:
A kind of transmission device of strand tensioning screw rod, it comprises a motor and by the tensioning screw rod of this motor-driven pair of opposing, described motor output shaft is connected with a major axis, and it also comprises: a pair of drive wheel, and they are disposed on the major axis and are driven by described motor; Described tensioning screw rod is driven with drive wheel by line belt and is connected.
The transmission device of described strand tensioning screw rod, it also comprises a pair of line belt Idle wheel, is separately positioned between the drive wheel.
The conjuncted motor reducer of the utility model is supplied with the enough power of whole device, drive wheel mechanism is connected transmission by line belt with the tensioning screw rod nut, tensioning screw rod nut mechanism advances when running or shrinks, the frictional force that nut brings by belt pulley is tightened or is loosened, when whole device started, skidding appearred in belt, adjusted the line belt degree of tightness by the Idle wheel bearing up pulley, make force localization at line belt, line belt plays the power transfer function of whole device.
Description of drawings
Below, the utility model is described in further detail in conjunction with the accompanying drawings:
Fig. 1 is a schematic representation of the present utility model.
Embodiment
