Description
Technical field
The present invention relates to hydraulic structure gantry gate hoists, especially relate to the one-way door type headstock gear possessing two-way gantry gate hoists function.
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 the gate suspension centre needing operation is positioned on several axis, preferably select two-way gantry gate hoists；When the gate suspension centre needing operation is positioned on the same axis consistent with headstock gear direction of travel, 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., and dolly is located on door frame, and the direction of travel of dolly is perpendicular with cart traffic direction.For large hydropower station project, dam bulk is big, aperture is many, equipment runs frequently, the water inlet Parallel to the flow direction in power station is disposed with trash rack, maintenance door and cleaning door etc., cleaning door uses a machine to arrange, so trash rack and maintenance door typically use two-way gantry gate hoists to operate by specification.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 medium waterpower generator station project, consider on the whole, arrange for simplifying import, shorten inlet pipeline length, being arranged with trash rack groove altogether by bulkhead gate, trash rack and maintenance door typically use one-way door type headstock gear to operate.
When operating many monoliths, many apertures bulkhead gate (or the trash racks) such as wasteway, flood discharging tunnel and powerplant intakes when one-way door type headstock gear, need to ensure that the lifting center of gravity position in every hole bulkhead gate (or trash rack) is consistent with the suspension centre center of one-way door type headstock gear, the most also need 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 differs, therefore, gate to be ensured 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.It is highly difficult that this allows for using one-way door type headstock gear to operate when lifting by crane the bulkhead gate of each monolith, greatly affects the operation safety in power station.If using two-way gantry gate hoists to replace one-way door type headstock gear to operate, although the lifting center of gravity COINCIDENCE PROBLEMS at suspension centre center and gate can effectively be solved, but there are two-way gantry gate hoists and arrange difficulty is big, construction costs is high problem, this is because when the consistent two-way gantry gate hoists of the parameters such as lifting capacity and lift compared with one-way door type headstock gear from weighing about big 30%-50%.
On the premise of reducing construction costs, how to solve the misaligned lifting difficult problem brought of porous port strobe center of gravity, be the problems always studied of those skilled in the art.
Summary of the invention
Present invention aim at providing a kind of one-way door type headstock gear possessing two-way gantry gate hoists function.
For achieving the above object, the present invention takes following technical proposals:
The one-way door type headstock gear possessing two-way gantry gate hoists function of the present invention, including door frame, it is arranged on the traveling mechanism of the larger traveller bottom described door frame, with the OPS being arranged on door frame, and it being arranged on the lifting mechanism on door frame crossbeam, described lifting mechanism is made up of the cable drum of motor-driven, running block, fixed pulley group and balance assembly pulley；Described cable drum fixes with door frame crossbeam, 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, described track is perpendicular to door frame traffic direction and is fixed on door frame crossbeam, being horizontally fixed with the electric pushrod with stroke inductive switch on door frame crossbeam, the expansion link end of described electric pushrod is hinged with horizontal bearing beam；Or: described cable drum and fixed pulley group fix with door frame crossbeam, described equalizer pulley group is fixed on horizontal bearing beam, described horizontal bearing beam slides or rolls and arranges in orbit, described track is perpendicular to door frame traffic direction and is fixed on door frame crossbeam, being horizontally fixed with the electric pushrod with stroke inductive switch on door frame crossbeam, the expansion link end of described electric pushrod is hinged with horizontal bearing beam.
Described horizontal bearing beam is slidably arranged on described track, it is fixed with slide block at horizontal bearing beam lower surface, the lower surface of described slide block offers mounting groove corresponding at orbital position, being fixed with self-lubricating abrasion-resistant block in described mounting groove, the side being positioned at guide rail on horizontal bearing beam is provided with directive wheel.
The invention has the advantages that the improvement to existing one-way door type headstock gear lifting mechanism, drive described horizontal bearing beam edge to be perpendicular to door frame traffic direction by described electric pushrod to move back and forth, described running block lifting center is carried out the position adjustment in direction, upstream and downstream, thus efficiently solves the porous bulkhead gate center of gravity non-overlapping problem that power station one-way door type headstock gear is frequently encountered by.Also make when arranging many apertures bulkhead gate (or trash rack) gate slot and wharf portal crane track simultaneously, the suspension centre center of every fan brake door and the deviation at gate slot center can not be considered, and directly the gate slot of all bulkhead gates is centrally disposed on a machine cart and runs orbit centre, enormously simplify the design of hydroulic sturcture, reduce the cost of hydroulic sturcture.
