The hydraulic balancing device comprises a hydraulic oil cylinder composed of a piston rod and a cylinder body, as well as an upper bearing plate and a lower bearing plate, wherein the upper bearing plate and the lower bearing plate are respectively fixed on the piston rod and the cylinder body, a plurality of locking screw rods are uniformly distributed in the circumferential direction of the hydraulic oil cylinder, and the two ends of each locking screw rod are respectively connected with the upper bearing plate and the lower bearing plate through an upper locking nut and a lower locking nut. The hydraulic balancing device disclosed by the utility model is simple in structure, reasonable in design, safe and reliable, thereby capable of being widely applied in the field of hydraulic and hydroelectric engineering ship lifts.
Description
Technical field
The utility model relates to Hydraulic and Hydro-Power Engineering ship lift field, particularly relates to a kind of ship lift wire rope hydraulic pressure balancer with mechanical interlocking function.
Background technology
The ship railway carriage or compartment of wire rope elevator lift-type vertical ship lift is by many wire rope suspensionings, maintenance level and guarantee respectively to organize the balancing tension of boom hoist cable when making the lifting of ship railway carriage or compartment, need the connecting portion in every boom hoist cable and ship railway carriage or compartment that one cover hydraulic pressure balancer is set respectively, adjusting the level in ship railway carriage or compartment by hydraulic system and balanced oil cylinder, and reach the purpose of respectively organizing the steel wire rope tension equilibrium after the adjustment.
The steel wire rope tension balancer that adopts on the ship lift before this all is not with mechanical interlocking, because can there be leakage in hydraulic jack inevitably under the steel wire rope tension effect, will cause inclination and the steel wire rope tension overload in ship railway carriage or compartment, thereby influence the safe operation of ship lift, have potential safety hazard.
The utility model content
The purpose of this utility model is in order to overcome the deficiency of above-mentioned background technology, a kind of ship lift wire rope hydraulic pressure balancer with mechanical interlocking function to be provided, making it have simple in structure, reasonable in design, safe and reliable characteristics.
A kind of ship lift wire rope hydraulic pressure balancer with mechanical interlocking function that the utility model provides, comprise the hydraulic jack that piston rod and cylinder body are formed, also comprise the last loaded plate and the following loaded plate that are individually fixed on piston rod and the cylinder body, described hydraulic jack circumferentially is evenly equipped with a plurality of tie down screws, and described tie down screw two ends link to each other with following loaded plate with last loaded plate respectively with lower locking nut by upper locking nut.
In technique scheme, the piston rod of described hydraulic jack down, described is gone up loaded plate and following loaded plate is individually fixed on piston rod and the cylinder body at last and cylinder body.
In technique scheme, described tie down screw, upper locking nut and lower locking nut are four.
Ship lift wire rope hydraulic pressure balancer with mechanical interlocking function of the present utility model, has following beneficial effect: by set up many group mechanical locking devices at hydraulic jack, removal mechanical interlocking in the process of leveling ship railway carriage or compartment, after the leveling of ship railway carriage or compartment with the mechanical locking device manual locking, to avoid leaking because of hydraulic jack during the ship elevator or booster causes the ship railway carriage or compartment to tilt and steel wire rope tension is unbalance, have simple in structure, reasonable in design, safe and reliable characteristics.
Description of drawings
Fig. 1 is the overall structure schematic diagram that the utlity model has the ship lift wire rope hydraulic pressure balancer of mechanical interlocking function.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail, but this embodiment should not be construed as restriction of the present utility model.
Referring to Fig. 1, the end of wire rope 7 is provided with wire rope tapered sleeve 8, be connected by gaily decorated basket nut 9 between described wire rope tapered sleeve 8 and the ship lift wire rope hydraulic pressure balancer that the utlity model has the mechanical interlocking function, the ship lift wire rope hydraulic pressure balancer bottom with mechanical interlocking function links to each other with ship railway carriage or compartment shackle plate 11 by hinge 10.
The ship lift wire rope hydraulic pressure balancer that the utlity model has the mechanical interlocking function comprises hydraulic jack 1, last loaded plate 2, following loaded plate 3, tie down screw 4, upper locking nut 5 and lower locking nut 6.
Described hydraulic jack 1 comprises piston rod 1.1 and cylinder body 1.2, the described loaded plate 2 of going up is individually fixed on piston rod 1.1 and the cylinder body 1.2 with following loaded plate 3, a plurality of tie down screws 4 are circumferentially uniform along hydraulic jack 1, and described tie down screw 4 links to each other with following loaded plate 3 with last loaded plate 2 respectively with lower locking nut 6 by upper locking nut 5.In the present embodiment, the piston rod 1.1 of described hydraulic jack 1 down, described is gone up loaded plate 2 and following loaded plate 3 is individually fixed on piston rod 1.1 and the cylinder body 1.2 at last and cylinder body 1.2; Described tie down screw 4, upper locking nut 5 and lower locking nut 6 are four.
Before by the (not shown) leveling of 1 pair of ship railway carriage or compartment of hydraulic jack, balanced each wire rope 7 tension force, the ship railway carriage or compartment is placed latched position and locking.
Unclamp the lower locking nut 6 of tie down screw 4 lower ends, open the switch valve (not shown) between each hydraulic jack 1, making on the same group, the identical oil pocket of hydraulic jack 1 is interconnected.Carry out leveling by hydraulic control system (not shown) and 1 pair of ship railway carriage or compartment of hydraulic jack, make simultaneously and respectively organize wire rope 7 with identical pulling force tensioning.After finishing the hydraulic pressure adjustment, the switch valve between the locking hydraulic jack 1.
Tighten the lower locking nut 6 of tie down screw 4 lower ends at last, piston rod 1.1 and the relative position of cylinder body 1.2 are remained unchanged.
When leakage or booster take place in hydraulic jack 1, can be guaranteed can not change because the change of piston rod 1.1 positions causes wire rope 7 tension force by the mechanical locking device that last loaded plate 2, following loaded plate 3, tie down screw 4, upper locking nut 5 and lower locking nut 6 are formed, thereby guarantee the level in ship railway carriage or compartment and the balancing tension of wire rope 7, improved the security reliability of ship elevator.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and modification interior.
The content that is not described in detail in this manual belongs to this area professional and technical personnel's known prior art.
