Description
Technical field
The present invention relates to a kind of mechanized bridge erection time for spanning release and regain push away bridge mechanism.
Background technology
At present, the erection mode of mechanized bridge mainly contains convertible and flat push type.When using flat push type erection mode, component main time erection frame is bridge erection, erection frame is arranged and pushes away bridge mechanism, utilize the pin gear pushed away on bridge mechanism to engage with the pin tooth in spanning, releasing and regaining spanning is a key technology, and current Application comparison is extensive.
What flat push type erection was in the past applied pushes away bridge mechanism form, be, in the middle part of erection frame, a drive shaft be housed, the driving mechanism of main shaft is arranged on inside erection frame, provides power by hydraulic motor, drive driving gear to engage with the driven gear be contained on main shaft, thus drive shaft is rotated; Main shaft both sides are provided with pin gear, and pin tooth is equipped with in the both sides of spanning bottom, and driving mechanism drive shaft is rotated, thus drive the pin gear of both sides to rotate; Engaged with pin tooth by pin gear, reach the object that spanning is released and regained.
There is following technical deficiency in the bridge mechanism form that pushes away in the past: because driving mechanism during erection needs to pass from bridge span structure bottom, and for avoiding interfering, the transverse direction in spanning connects crossbeam position and can not arrange on the lower, affects the lateral stability of spanning; Drive hydraulic motor size to be restricted, the hydraulic motor of larger driving torque can not be selected, have impact on the ability that mechanized bridge erection overcomes the bank slope discrepancy in elevation; The connecting line distance bridge span structure of hydraulic motor is comparatively near, affects job security; Gear pair transmission requires all higher to the machining accuracy of component and installation accuracy, and environment for use requires higher, and reliability is poor, fault rate is higher, and the wear of gears that works long hours causes gap comparatively large, affects transmission efficiency, can only carry out replacing to gear can not adjust, maintainability is poor
.
Summary of the invention
The present invention be directed to above-mentioned the deficiencies in the prior art, there is provided one not affect bridge span structure design, provide more large driving force, raising job security, strong, the convenient manufacture processing of accommodative ability of environment and installation and maintenance, that moves spanning when setting up for mechanized bridge pushes away bridge mechanism.
The technical scheme that a kind of mechanized bridge of the present invention pushes away bridge mechanism is: comprise hydraulic motor, drive sprocket, motor mount, capping, tensioning apparatus, chain, driven sprocket, push away bridge axle, bearing support, pin gear; Drive sprocket by spline joint on hydraulic motor output shaft, hydraulic motor is laterally fixed in motor mount its right end face by bolt, motor mount is that internal and external stopper, face of cylinder windowing form of structure are worn in circular pipe type two ends, left side seam connects with erection frame, right side seam connects with hydraulic motor, face of cylinder window is used for chain to be passed through, and left end face is laterally fixed on erection frame by bolt; Driven sprocket is assemblied in by spline and pushes away the position that to keep left in the middle part of bridge axle, and pin gear is connected in by spline symmetry and pushes away bridge axle two ends, pushes away bridge axle and is supported on two bearing supports, and bearing support is arranged on erection frame by bolt symmetry; Drive sprocket is connected by chain with driven sprocket; Tensioning apparatus is dovetail slide block structure form, and be bolted on erection frame, short transverse is between drive sprocket and driven sprocket; Capping is arranged on erection frame by bolt.Wherein fluid motor-driven drive sprocket rotates, by chain connection for transmission, driven sprocket is rotated, thus drive the bridge axle that pushes away be arranged on bearing support to rotate, the pin gear that drive installation is pushing away bridge axle both sides rotates, engaged with the pin tooth in spanning by pin gear, release and regain spanning; Tensioning apparatus can move left and right certain distance along slide block, the tightness of adjustment chain.
The above-mentioned advantage pushing away bridge mechanism is, during erection, driving mechanism is not through bridge span structure bottom, so design attitude spanning laterally connecting crossbeam can move down, adds the lateral stability of spanning; Owing to not limiting by installing space, the hydraulic motor of more large driving force square can be selected, thus effectively can improve the ability that mechanized bridge overcomes the bank slope discrepancy in elevation; The connecting line distance bridge span structure of hydraulic motor is comparatively far away, improves job security; Usage chain transmission device, require lower to the machining accuracy of component and installation accuracy, environment for use requires lower, reliability is better, and fault rate is lower, and is provided with tensioning apparatus, can adjusting chain tightness after work certain hour, do not affect transmission efficiency, maintainability is better
