Abstract
The utility model relates to a movable elevating mechanism for vertical-lift gate with multi-lift-points, belonging to the water conservancy machinery class. The utility model is able to be used on large dams of small and medium hydraulic power plants to start and stop entrance gates of generator set, large dam flood gates and bottom hole sand gates. The mechanism is equipped with an inclined lift hook, able to be deflected toward an upstream direction of a large dam and do trash screen lifting operations. When operated the utility model is cooperated with a flexible wire rope and makes a machine and the large dam speedily fixed into one body, realizing the safe inclined hoisting and uplifting work. The utility model expands uplifting ranges of a headstock gear, reduces engineering matching lifting implements and debases cost. Besides, the utility model is more suitable for construction requirements of small and medium hydraulic power plants, worth popularization applications.
Description
The utility model has related to a kind of many suspension centres of movable type gantry gate hoists, and it is mechanical to belong to water conservancy project.Can be used for making the entrance gate of water wheels unit on the medium waterpower generator station dam, floodgate, and the keying usefulness of the husky gate of bottom outlet, and can make oblique suspension hook make unit trashrack lifting operation by auxiliary body to the deflection of dam updrift side.
The structural shape of employed portable gantry gate hoists and the utility model are extremely similar on the present domestic Large River.This class is applied in the headstock gear on the Large River, acts on singlely, disposes singlely, and quantity is a lot.Because construction costs is big doubly more a lot of than purchasing an opening and closing device expense far away, therefore never considers taking into account of work, so long as safety, reliable, zero defects.Do not stint again, add lifting operation, seldom allow, so the selection of lifting facility also is a kind of so single principle of vertical lifting not in the operation of vertical orientation.
But along with development of science and technology, and the needs of China's national situation, the lifting appliance of this single homework uses passable on the large hydropower station engineering, then can not take into account but use on medium waterpower generator station.Particularly economy has become under the important indicator situation, the scale of investment of building, and the pattern of investment all can not be compared with large-scale power station, the deficiency of fund, but the needs on the engineering can not reduce again, thereby have just produced safe in utilization, reliably a tractor serves several purposes in the scope, the machinery of multimachine coupling, the regulation on the standard also will be slightly flexible to some extent.This with regard to exposed lifting appliance on the dam of existing big power station be applied in weak point in the small plant.
The purpose of this utility model avoids the lifting appliance on the above-mentioned existing large-scale power station dam to be applied to the deficiency of lifting by crane in the middle small plant with regard to being, and a kind of a tractor serves several purposes is provided, and can carry out coaxial respectively and unit entrance gate that put.The keying of dam flood-discharge gate, the bottom outlet scouring sluice opens and closes, and can carry out portable many suspension centres gantry gate hoists of unit entrance gate upstream trashrack lifting operation again.
The utility model can reach by following measure: by machine room, door frame, main suspension hook, oblique suspension hook, walking mechanism, the utility model that insurance institution etc. form, by cable power supply is input in the machine, under the driver's cabin centralized control, machine is by the walking gear, any one the unit place on dam of can travelling, carry out the unit entrance gate by main suspension hook, the lifting of the husky gate of floodgate bottom outlet with close, and can use oblique suspension hook, the trashrack of unit import updrift side is carried out lifting operation, and by insurance institution, can make complete machine safe and reliable carry out the inclined pull hoisting operation.
The utility model can also reach by following measure, is provided with to make main suspension hook tiltedly suspension hook deceleration, gear machine room at the uniform velocity above machine, driver's cabin is equipped with, cable drum, balance weight in the middle part, by staircase, operator or maintainer can be gone to full machine everywhere.With rail clamping device full machine is fixed on the rail during machinery operation.
The accompanying drawing drawing is described as follows:
Fig. 1 is the portable many suspension centres gantry gate hoists of the utility model elevations
Fig. 2 is the portable many suspension centres gantry gate hoists of the utility model left side views
The utility model is described in further detail below in conjunction with accompanying drawing embodiment:
Shown in Fig. 1, Fig. 2: the utility model is a kind of tower structure, as the pattern of same door, is provided with the machine room (1) of main suspension hook (3) and oblique suspension hook (11) lifting with gear on door frame (2) top, main suspension hook (3) can be 2, also can be one, generally be designed to two, on the lifting amount, on the lifting speed, basically be consistent, in constant speed, synchronously, carry out lifting operation at the uniform velocity down, main suspension hook operation is along vertically.Tiltedly suspension hook (11) can be to the big embankment lifting of upstream tilting, maximum 10 ° of angle of inclination, and with the trashrack in lifting unit the place ahead, production line is by tiltedly hanging center line (14) lifting operation, the lifting amount flood retention grid of should be able to slinging are foundation.Have driver's cabin (4) that full machine is carried out centralized control at door frame (2) middle part, also have cable drum (5), balance weight (6) can freely be involved on the reel machine cable in walking.Along staircase (7), operating personnel can arrive driver's cabin (4), and the maintenance personal can arrive machine operation everywhere.Walking dolly (8) is arranged at door frame (2) bottom, can be along track travel on dam.The left alone without help industry that gives in each unit place by walking gear (10), changes the speed of travel, and by rail clamping device (9) walking dolly (8) is fixed on the rail.
The utility model uses main suspension hook (3) when vertical lifting, when oblique suspension hook (11) operation, to filling out roam all around the would lifts trashrack from every hole unit to oblique 10 ° of angles greatly.By calculate, tiltedly hang stable by assurance for the closed-in construction of machine itself, safety, reliable.But to be on the safe side, be provided with hook (16), and on dam foundation, be provided with hook (15) on door frame (2) top, by flexible steel cable (12), with quick loading and unloading head (17), door frame (2) and dam foundation are combined as a whole, the accident of providing against any misfortune occurs.
The utility model has following advantages compared to existing technology:
1), adopted oblique suspension hook, enlarged the machine scope of application.
2), a machine dual-purpose, saved the facility of a lifting trash rack, saved engineering cost, and cost of use.
3), adopted insurance institution, make that tiltedly to hang safety more secure, eliminate unsafe factor.
4), adopted quick loading and unloading chuck, saved the non-cutting time in using, changes convenient and reliable quick.
This reality is novel has some change to the lifting standard owing to adopted oblique suspension hook operation, owing to adopted the security insurance measure, makes in the enforcement more reliable.Because a machine dual-purpose has enlarged the scope of application, is the design with prospect, particularly middle small plant will make some facility couplings thus, reduces construction costs greatly,
