Abstract
The utility model relates to a lifting device for opening a balance valve of a gate; the middle of the gate is movably connected with a vertical lifting rod, on which a cover plate is arranged; two elbows are symmetrically arranged on the gate; one end of each elbow is located in the gate and the other end is upwards and buckled with the lower surface of the cover plate; the upper part of the lifting rod stretches out from the gate and a locating pin; a strip hole matching with the locating pin is arranged in the middle of an oscillating rod; a locating base is arranged above the gate; one end of the oscillating rod is connected with the locating base and the other end is connected with a steel wire rope; and the upper part of the steel wire rope is connected with the hook of the gate frame. When needed, the lifting device for opening the balance valve of the gate can be lifted artificially; the crane is not needed to be online always; and the lifting device overcomes the waste of manpower and material resources.
Description
Technical field
The utility model relates to a kind of lifting appliance of opening for gate equalizing valve, for the gate opening device of nuclear power station draining.
Background technology
At present the nuclear power station convenience of bringing to us of generating electricity has been widely known thing in its people, the generating of nuclear power has brought a lot of Gospels to us, in the process of generating, when being nuclear power maintenance, gate uses, therefore also play very important effect, its each parts, each part are vital.Present most gate still adopts artificial crane presence, has wasted a large amount of manpower and materials.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of lifting appliance of opening for gate equalizing valve, and this lifting appliance that is used for the unlatching of gate equalizing valve can manually promote when needed, does not need crane always online, has overcome the waste of manpower and materials.
For overcoming the above problems, concrete technical scheme of the present utility model is as follows: a kind of lifting appliance of opening for gate equalizing valve, be connected with vertical-lifting bar at the middle part of gate, and on lifting arm, be provided with cover plate; On gate, be arranged with two elbows, one end of elbow is positioned at the inner side of gate, and the other end of elbow upwards, and fastens with the soffit of cover plate; The top of lifting arm is stretched out gate and is stretched out alignment pin, and the middle part of fork is provided with strip hole, and this strip hole coordinates with alignment pin, above gate, be provided with positioning seat, one end of fork is connected with positioning seat, other end connecting steel wire ropes, and the top of wire rope is connected with the hook of gate framework.
The top of described wire rope is provided with connecting ring and enhancing ring successively, and connecting ring or enhancing ring are connected with the hook of gate framework.
This lifting appliance that is used for the unlatching of gate equalizing valve adopts wire rope to drive the motion of lifting arm by fork, thereby realizes the opening and closing of elbow, makes the both sides of gate form pressure reduction.
Top at wire rope is provided with connecting ring and enhancing ring successively, and the location being used for to lifting arm, to guarantee the position of cover plate opening and closing.
Accompanying drawing explanation
Fig. 1 is the structural representation for the lifting appliance of gate equalizing valve unlatching.
Fig. 2 is the concrete structure schematic diagram on wire rope top.
The specific embodiment
As shown in Figure 1, a kind of lifting appliance of opening for gate equalizing valve, is connected with vertical-lifting bar 2 at the middle part of gate 1, is provided with cover plate 3 on lifting arm 2; On gate 1, be arranged with two elbows 4, one end of elbow 4 is positioned at the inner side of gate 1, and the other end of elbow 4 upwards, and fastens with the soffit of cover plate 3; The top of lifting arm 2 is stretched out gate 1 and is stretched out alignment pin 5, the middle part of fork 6 is provided with strip hole, this strip hole coordinates with alignment pin 5, above gate 1, be provided with positioning seat 7, one end of fork 6 is connected with positioning seat 7, other end connecting steel wire ropes 8, the top of wire rope 8 is connected with the hook 9 of gate framework.In the time that wire rope 8 is upwards mentioned, fork 6 upwards rotates take positioning seat 7 as fulcrum, carries thereby drive on lifting arm 2, elbow 4 tops is opened, thereby the water in gate 1 is emitted, and the process of valve-off is contrary with unlatching phase process.
As shown in Figure 2, the top of described wire rope 8 is provided with connecting ring 11 and enhancing ring 12 successively, and connecting ring 11 or enhancing ring 12 are connected with the hook 9 of gate framework.Connecting ring 11 is connected with hook 9, and the position of cover plate 3 is closed condition, and in the time that enhancing ring 12 is connected with hook 9, the position of cover plate 3 is opening, has saved manpower.
