Description
Technical field
The present invention relates to hydraulic structure gantry gate hoists, more particularly, to the list for possessing two-way gantry gate hoists function
To gantry gate hoists.
Background technology
At present, power station gantry headstock gear is divided into two-way gantry gate hoists and one-way door type headstock gear.Operated when needs
When gate suspension centre is located on several axis, preferably from two-way gantry gate hoists；When the gate suspension centre for needing to operate is located at and keying
When on the consistent same axis of machine direction of travel, one-way door type headstock gear is typically preferably selected.
The walking dolly, door frame, traveling mechanism of the larger traveller of two-way gantry gate hoists by being provided with lifting mechanism etc. forms, dolly
It is located on door frame, the direction of travel and cart traffic direction of dolly are perpendicular.For large hydropower station project, dam bulk
Greatly, aperture is more, and equipment operation is frequent, and the water inlet Parallel to the flow direction in power station is disposed with trash rack, maintenance door and cleaning door
Arranged Deng, cleaning door using a machine by specification, so trash rack and maintenance door are typically operated using two-way gantry gate hoists.
In view of the maintenance for the hydraulic headstock gear for opening and closing main gate, typically also revolution is set to hang on two-way gantry gate hoists.
One-way door type headstock gear is made up of lifting mechanism, door frame and traveling mechanism of the larger traveller etc., and lifting mechanism is directly arranged at
Plane on door frame.One-way door type headstock gear is only capable of running along cart orbital direction by traveling mechanism of the larger traveller, for middle-size and small-size water
Power station project, considers on the whole, to simplify import arrangement, shortens inlet pipeline length, by bulkhead gate and the common groove of trash rack
Arrangement, trash rack and maintenance door are typically operated using one-way door type headstock gear.
When one-way door type headstock gear operates more monoliths, more aperture bulkhead gates such as wasteway, flood discharging tunnel and powerplant intakes
（Or trash rack）When, every hole bulkhead gate need to be ensured（Or trash rack）Lifting center of gravity position and one-way door type headstock gear suspension centre
Center is consistent, while also needs to ensure the deviation of dam cast-in-place concrete gate slot or the error of gate embedded part installation.But
Due to bulkhead gate（Or trash rack）Structure in upstream and downstream direction be asymmetric arrangement, and each monolith bulkhead gate size is big
It is small to differ, thus, it is ensured that the design of gate and embedded part, manufacture and installation deviation are more difficult within the limits prescribed, gate slot
Concreting deviation is even more to be difficult to hold, and dam height is higher, and its deviation is bigger.This allows for using one-way door type headstock gear
Operated during the bulkhead gate for lifting by crane each monolith it is highly difficult, greatly influence power station it is safe for operation.If using bidirectional gate
Formula headstock gear is operated instead of one-way door type headstock gear, is overlapped although suspension centre center can effectively be solved with the lifting center of gravity of gate
Problem, but the problem of two-way gantry gate hoists arrangement difficulty is big, construction costs is high be present, because when lifting capacity is with raising
The consistent two-way gantry gate hoists of the parameters such as journey weigh about big 30%-50% certainly compared with one-way door type headstock gear.
How to solve the misaligned lifting problem brought of porous port strobe center of gravity on the premise of construction costs is reduced, be this
The problem that art personnel study always.
The content of the invention

Cable drum, running block, fixed pulley group and the balance assembly pulley that described lifting mechanism is driven by motor are formed；It is described
Cable drum is mutually fixed with door frame crossbeam, and the fixed pulley group and balance assembly pulley are fixed on horizontal bearing beam, the water
Flat carrier bar is slided or rolled and sets in orbit, and the track is fixed on door frame crossbeam perpendicular to door frame traffic direction,
The electric pushrod with stroke inductive switch, telescopic rod end and the level of the electric pushrod are horizontally fixed with door frame crossbeam
Carrier bar is hinged；Or：The cable drum and fixed pulley group are mutually fixed with door frame crossbeam, and the equalizer pulley group is fixed on
On horizontal bearing beam, the horizontal bearing beam is slided or rolled and sets in orbit, and the track is perpendicular to door frame traffic direction
It is fixed on door frame crossbeam, is horizontally fixed with the electric pushrod with stroke inductive switch on door frame crossbeam, it is described electronic to push away
The telescopic rod end of bar is hinged with horizontal bearing beam.
The horizontal bearing beam is slidably arranged on the track, and sliding block is fixed with horizontal bearing beam lower surface, described
The lower surface of sliding block, which corresponds at orbital position, offers mounting groove, self-lubricating abrasion-resistant block is fixed with the mounting groove, in water
Side on flat carrier bar positioned at guide rail is provided with directive wheel.
The invention has the advantages that the improvement to existing one-way door type headstock gear lifting mechanism, is driven by the electric pushrod
The horizontal bearing beam carries out upstream and downstream along being moved back and forth perpendicular to door frame traffic direction, to running block lifting center
The position adjustment in direction, so as to efficiently solve the porous bulkhead gate center of gravity that power station one-way door type headstock gear frequently encounters
Non-overlapping problem.Also cause arranging more aperture bulkhead gates simultaneously（Or trash rack）When gate slot and wharf portal crane track, it can not examine
Consider the deviation at the suspension centre center and gate slot center per fan brake door, and the gate slot of all bulkhead gates is directly centrally disposed on a machine
Cart running track center, enormously simplify the design of hydroulic sturcture, reduces hydroulic sturcture
Cost.
