Technical field
This utility model relates to a kind of vertical ship lift many ring flanges equilibrium oil cylinder, belongs to the equilibrium of vertical ship lift ship reception chamber
Oil cylinder technical field.
Background technology
Vertical ship lift is the mechanical facility of a kind of lift vessel, and its work process is as follows: downstream ship is sailed through approach channel
Enter the ship reception chamber of vertical ship lift, be then shut off aft-gate, by vertical ship lift, ship reception chamber is promoted at upper gate,
Then opening upper gate, ship sails upstream into.Equilibrium oil cylinder is connected between ship reception chamber and steel wire rope, by regulation equilibrium oil
The collapsing length of cylinder adjusts the levelness of boat supporting case.Owing to ship lift bearing capacity is usually more than kiloton, in order to ensure huge
Bearing capacity is not exclusively born by hydraulic means, and hydraulic jack locks by oil pressure simultaneously, for flexibly connecting, may go out after long-term work
Stretching the most in various degree, affects the levelness of ship reception chamber, therefore after each equilibrium oil cylinder is adjusted in place, at equilibrium cylinder block
And additionally use 4 screw rods between expansion link and be rigidly connected.Ship reception chamber levelness is had influence on, directly in order to avoid bolt and nut loosens
Connect and nut is welded extremely with screw rod.
After ship lift longtime running, unavoidable steel wire rope self exists flexible, needs after the certain time limit of ship elevator simultaneously
Carry out repair and maintenance.Owing to screw rod is the most welded extremely, it is impossible to again with, screw rod can only be cut off, the equilibrium oil the most more renewed
Cylinder, causes the wasting of resources.
In order to overcome above-mentioned deficiency, Chinese patent " ZL201520753508.9 " one reuses vertical ship lift equilibrium
The device of oil cylinder, by increasing the quantity of fixing hole on ring flange, it is achieved being used for multiple times of equilibrium oil cylinder.But above-mentioned patent is still deposited
In deficiency.Owing to the quantity of fixing hole increases on ring flange, the size quantity also with fixing hole of ring flange will certainly be caused
Increasing and become big, in the case of bearing equal load, the moment of flexure that ring flange bears also can become big.Owing to being limited by the strength of materials
System, ring flange size can not unrestrictedly increase, and directly affect equilibrium oil cylinder reuses number of times.
Summary of the invention
The purpose of this utility model is, it is provided that a kind of vertical ship lift many ring flanges equilibrium oil cylinder, so that equilibrium oil cylinder
Access times be multiplied, improve resource utilization further, thus overcome the ring flange size in prior art can not be unlimited
The restriction that system increases.
The technical solution of the utility model is achieved in that
A kind of vertical ship lift many ring flanges equilibrium oil cylinder of the present utility model, including cylinder body and expansion link；Cylinder ends
It is provided with hanger；Expansion link end is provided with suspension ring；One group of ring flange it is respectively equipped with, on cylinder body and expansion link on cylinder body and expansion link
Ring flange quantity is equal；Ring flange is provided with one group of fixing hole being uniformly distributed along the circumference.
In aforementioned many ring flanges equilibrium oil cylinder, the spacing between described one group of ring flange is slightly larger than the thickness of two fixing nuts
Degree.
Owing to have employed technique scheme, compared with prior art, this utility model is by increasing method for this utility model
The mode of blue dish quantity realizes equalizing oil cylinder and utilizes being multiplied of number of times, improves resource utilization, is greatly saved cost；Flange
Depending on dish, the quantity in hole can be according to requirement of engineering and the strength of materials, motility is strong；This utility model can according to requirement of engineering and
Aesthetic property, is designed to square, circular or other shapes by ring flange.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of prior art；
Fig. 3 is using method schematic diagram.
Figure is labeled as: 1-cylinder body, 2-expansion link, 3-hanger, 4-suspension ring, 5-ring flange, 6-fixing hole, 7-fix spiral shell
Mother, 8-screw rod, 9-steel wire rope, 10-flap seat, 11-ship reception chamber, 12-equilibrium oil cylinder, screw rod cut-off for 13-, 14-pad.
Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings, but not as new to this practicality
Any restriction of type.
A kind of vertical ship lift many ring flanges equilibrium oil cylinder of the present utility model, as it is shown in figure 1, include cylinder body 1 and stretch
Bar 2；Cylinder body 1 end is provided with hanger 3；Expansion link 2 end is provided with suspension ring 4；One group of flange it is respectively equipped with on cylinder body 1 and expansion link 2
Ring flange 5 quantity on dish 5, cylinder body 1 and expansion link 2 is equal；Ring flange 5 is provided with one group of fixing hole being uniformly distributed along the circumference 6.One
Spacing between group ring flange 5 is slightly larger than the thickness of two fixing nuts 7.
A kind of repeated using method for above-mentioned vertical ship lift many ring flanges equilibrium oil cylinder is, the method is when rising ship
When machine carries out repair and maintenance, first ship reception chamber 11 is positioned on locking device, then loosens steel wire rope 9；Will equilibrium cylinder flange dish
Between connection screw rod cut off；Regulate the oil pressure of each equilibrium oil cylinder, make ship reception chamber 11 again become level；Then at outermost
On the ring flange of a pair, side, 4 centrosymmetric fixing holes 6 are chosen in remaining hole and screw rod 8 and fixing nut 7 are installed, oil cylinder will be equalized
