Abstract
The utility model relates to a water-stopping rubber protective device of a flat steel gate, in particular to water-stopping rubber of the flat steel gate and an opening/closing method of the flat steel gate. The water-stopping rubber protective device is characterized in that a hydraulic oil cylinder flange is welded on a frame of a door body; a hydraulic oil cylinder is fixedly arranged on the frame of the door body through a hydraulic cylinder flange; a guide wheel is mounted to the piston rod of the hydraulic oil cylinder; a hole is formed on the frame of the door body; the piston rod of the hydraulic oil cylinder and the guide wheel are embedded in the hole; the piston rod of the hydraulic oil cylinder and the guide wheel are higher than the water-stopping rubber and propped against the wall of a guide slot above, so that the water-stopping rubber is separated from the wall of the guide slot; and the hydraulic oil cylinder is connected with a hydraulic pump station on a platform through a high pressure corrosion-proof hose. The utility model has the advantages that the water-stopping rubber can be protected to ensure reliable sealing between the water-stopping rubber and the guide slot, which further reduces the leakage of the steel gate; the force of opening or closing the gate can be effectively reduced; and the time of water filling and pressure balancing can be greatly reduced, so as to improve the work efficiency.
Description
Technical field
The utility model relates to a kind of water stop rubber protection device for flat steel gate, specifically the keying of the watertight rubber of plane steel gate and gate.
Background technology
Watertight rubber is the important component part of plane steel gate, realizes gate damming to water by the sealing function of it and gate guide groove.The opening/shutting mode of general closed planar gate is divided into hydrostatic and opens and closes and move the water keying.
Plane steel gate comprises compositions such as gate guide groove, steel sluice gate body and water-filling equalizing valve.Be applicable in the engineerings such as power plant's water intaking, draining, sewerage treatment, cooperate with the gate guide groove to be installed on pump works water inlet or conduit entrance position, delivery port etc.
The plane steel gate simple structure, it is little to take up room, and is convenient to safeguard.Generally comprise a body and gate guide groove embedded part two parts, the door body is made of panel and framework, support running gear, suspender water sealing part.Gate guide groove embedded part is made of guide groove, ground sill, lintel.
In prior art, watertight rubber does not have protective device in opening-closing process, and watertight rubber is easy to carry out violent friction with the guide groove wall under the effect of hydraulic pressure, also causes the turnup even the damage of watertight rubber in the aggravation hoisting capacity.Special containing at some in the bad water of water quality such as a large amount of foreign material grains of sand, slight friction just can cause pulling, scratching of watertight rubber, cause sealing bad, the leakage rate increasing.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of water stop rubber protection device for flat steel gate is provided, and can play the effect of protection watertight rubber and can reduce hoisting capacity in keying.
The technical scheme that provides according to the utility model; water stop rubber protection device for flat steel gate comprises a body; watertight rubber; guide groove; hydraulic jack and water-filling equalizing valve; the water-filling equalizing valve is installed on the door body; watertight rubber is arranged on the body; feature is: the hydraulic jack flange is welded on the body framework; install and fix hydraulic jack by the hydraulic cylinder flange on the framework of described door body; tailpiece of the piston rod at hydraulic jack is installed guide wheel; offer a hole on the described door body framework; fill in the piston rod and the guide wheel of hydraulic jack in the hole; the height that the piston rod of hydraulic jack and guide wheel exceed watertight rubber withstands on the guide groove wall; watertight rubber is separated with the guide groove wall, and hydraulic jack is connected with hydraulic power unit on the platform by the anticorrosion flexible pipe of high pressure.
Offer draw-in groove above the described hydraulic jack, draw-in groove and the clamping of segmented flange are connected with the flange of door on the body by bolt, have made things convenient for the dismounting maintenance.Described hole is a rectangle, is positioned at the watertight rubber outside.
Compared with the prior art the utility model has the following advantages:
1, the utility model can well be protected watertight rubber, can make the sealing of watertight rubber and guide groove reliable, thereby make the leakage rate of steel gate littler.
2, when opening and closing owing to overcome the direct friction of watertight rubber and guide groove, and the hydraulic jack rod end has guide wheel, becomes rolling friction by original sliding friction, thereby effectively reduced the hoisting capacity of gate.
3. during starting gate, before gate both sides water-head does not reach permissible value, open the utility model device, the formula of can also leaking concora crush, cooperate the water-filling equalizing valve to make the meet water water of side of a body flow into land side rapidly, saved the water-filling concora crush time greatly, thereby improved operating efficiency.

Fig. 2 is the utility model structure vertical view.
Fig. 3 is the utility model hydraulic jack structural representation.
Fig. 4 is the utility model hydraulic jack segmentation flange structural representation.
The specific embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
As Fig. 1～shown in Figure 4: comprise a body 1, watertight rubber 2, guide groove 3, hydraulic jack 4 guide wheels 5, hydraulic jack flange 6, water-filling equalizing valve 7, draw-in groove 8 and segmented flange 9.
The utility model adopts water-filling equalizing valve 7 is installed on door body 1, watertight rubber 2 is arranged on the body 1, hydraulic jack flange 6 is welded on a body 1 framework, install and fix hydraulic jack 4 by hydraulic cylinder flange 6 on the framework of described door body 1, tailpiece of the piston rod at hydraulic jack 4 is installed guide wheel 5, offers a slot on described door body 1 framework, and hole size can be filled in the piston rod and the guide wheel 5 of hydraulic jack 4, the hole is positioned at watertight rubber 2 outsides, can seal for avoiding leaking like this.When the steel gate opening/closing, Open valve makes hydraulic cylinder jack-up, and the height that the piston rod of hydraulic jack 4 and guide wheel 5 exceed watertight rubber 2 withstands on guide groove 3 walls, and watertight rubber 2 is separated with guide groove 3 walls, thereby has avoided the friction of watertight rubber and guide groove wall.
Fig. 3, shown in Figure 4 offers draw-in groove 8 above the described hydraulic jack 4, and the flange on the hydraulic jack 49 is made segmented, with oil cylinder draw-in groove 8 mating reactions shown in Figure 3, fixedlys connected with the flange on being welded on a body framework by bolt.This structure is more conducive to dismounting and safeguards.
Described hydraulic jack 4 is connected the implementation Long-distance Control by the anticorrosion flexible pipe of high pressure with hydraulic power unit on the platform.When gate hangs in guide groove when closing by suspender, open hydraulic jack, the rod end guide wheel ejects, and the protection watertight rubber is not rubbed.The gate back control hydraulic jack retraction that puts in place, gate are combined closely with the guide groove wall under hydraulic action, and realizing dams cuts off the water supply.When gate need be opened, by bath equalizing valve water-filling or internode water-filling realize both sides concora crush or water-head reach allow design load after, open hydraulic jack, in gate is sling process, protect watertight rubber not to be subjected to violent friction once again.Under specific permission situation, open in advance and can also use as the water-filling surge suppressor, saved the gate land side filling time greatly.
