Description
Technical field
This utility model relates to hydraulic structure gantry gate hoists, especially relates to possess two-way gantry gate hoists function
One-way door type headstock gear.
Background technology
At present, power station gantry headstock gear is divided into two-way gantry gate hoists and one-way door type headstock gear.When needing operation
When gate suspension centre is positioned on several axis, preferably select two-way gantry gate hoists；When the gate suspension centre needing operation is positioned at and opens and closes
Time on the same axis that machine direction of travel is consistent, the most preferably select one-way door type headstock gear.
Two-way gantry gate hoists are formed by being provided with the walking dolly of lifting mechanism, door frame, traveling mechanism of the larger traveller etc., dolly
Being located on door frame, the direction of travel of dolly is perpendicular with cart traffic direction.For large hydropower station project, dam bulk
Greatly, aperture is many, and equipment runs frequently, and the water inlet Parallel to the flow direction in power station is disposed with trash rack, maintenance door and cleaning door
Deng, cleaning door uses a machine to arrange by specification, so trash rack and maintenance door typically use two-way gantry gate hoists to operate.
In view of the maintenance of the hydraulic headstock gear opening and closing main gate, the most also revolution is set on two-way gantry gate hoists and hang.
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 relying on traveling mechanism of the larger traveller to run along cart orbital direction, for middle-size and small-size water
Power station project, considers on the whole, arranges for simplifying import, shortens inlet pipeline length, by bulkhead gate and trash rack groove altogether
Arranging, trash rack and maintenance door typically use one-way door type headstock gear to operate.
Many monoliths, many apertures bulkhead gates such as wasteway, flood discharging tunnel and powerplant intakes is operated when one-way door type headstock gear
Time (or trash rack), the lifting center of gravity position in every hole bulkhead gate (or trash rack) and the suspension centre of one-way door type headstock gear need to be ensured
Center is consistent, the most also needs to ensure the error that the deviation of dam cast-in-place concrete gate slot or gate embedded part are installed.But,
Owing to the structure of bulkhead gate (or trash rack) is asymmetric arrangement in direction, upstream and downstream, and each monolith bulkhead gate size is big
Little differ, thus, it is ensured that gate and the design of embedded part, manufacture and installation deviation the most more difficulty, gate slot
Concreting deviation is difficult to hold especially, and dam height is the highest, and its deviation is the biggest.This allows for using one-way door type headstock gear
Operate highly difficult when lifting by crane the bulkhead gate of each monolith, greatly affect the operation safety in power station.If employing bidirectional gate
Formula headstock gear replaces one-way door type headstock gear to operate, although can effectively solve suspension centre center and overlap with the lifting center of gravity of gate
Problem, but there is the problem that two-way gantry gate hoists arrange that difficulty is big, construction costs is high, this is because work as lifting capacity and raise
The two-way gantry gate hoists that the parameters such as journey are consistent weigh about big 30%-50% compared with one-way door type headstock gear certainly.
How on the premise of reducing construction costs, to solve the misaligned lifting difficult problem brought of porous port strobe center of gravity, be this
The problem that skilled person studies always.
Summary of the invention
This utility model purpose is to provide a kind of one-way door type headstock gear possessing two-way gantry gate hoists function.
For achieving the above object, this utility model takes following technical proposals:
The one-way door type headstock gear possessing two-way gantry gate hoists function described in the utility model, including door frame, is arranged on
Traveling mechanism of the larger traveller bottom described door frame, and the OPS being arranged on door frame, and it is arranged on hoisting on door frame crossbeam
Mechanism, described lifting mechanism is by the cable drum of motor-driven, running block, fixed pulley group and balance assembly pulley structure
Become；Described cable drum fixes with door frame crossbeam, and described fixed pulley group and balance assembly pulley are fixed on horizontal bearing beam,
Described horizontal bearing beam slides or rolls and arranges in orbit, and described track is perpendicular to door frame traffic direction and is fixed on door frame crossbeam
On, door frame crossbeam is horizontally fixed with the electric pushrod with stroke inductive switch, the expansion link end of described electric pushrod
It is hinged with horizontal bearing beam；Or: described cable drum and fixed pulley group fix with door frame crossbeam, described equalizer pulley group
Being fixed on horizontal bearing beam, described horizontal bearing beam slides or rolls and arranges in orbit, and described track is perpendicular to door frame fortune
Line direction is fixed on door frame crossbeam, is horizontally fixed with the electric pushrod with stroke inductive switch on door frame crossbeam, described
The expansion link end of electric pushrod is hinged with horizontal bearing beam.
Described horizontal bearing beam is slidably arranged on described track, is fixed with slide block at horizontal bearing beam lower surface, described
The lower surface of slide block offers mounting groove corresponding at orbital position, is fixed with self-lubricating abrasion-resistant block, at water in described mounting groove
The side being positioned at guide rail on flat carrier bar is provided with directive wheel.
This utility model advantage is the improvement to existing one-way door type headstock gear lifting mechanism, by described electric pushrod
Drive described horizontal bearing beam edge to be perpendicular to door frame traffic direction to move back and forth, described running block lifting center is carried out above,
The position adjustment of downstream direction, thus efficiently solve the porous bulkhead gate that power station one-way door type headstock gear is frequently encountered by
Center of gravity non-overlapping problem.Also make when arranging many apertures bulkhead gate (or trash rack) gate slot and wharf portal crane track simultaneously, permissible
Do not consider the suspension centre center of every fan brake door and the deviation at gate slot center, and directly the gate slot of all bulkhead gates is centrally disposed on
Door machine cart runs orbit centre, enormously simplify the design of hydroulic sturcture, reduces power station water conservancy project and build
Build the cost of thing.
