The device can protect the water stop rubber and ensure reliable sealing between the water stop rubber and the guide channel, so the leakage of the steel gate is smaller; the device can effectively reduce the starting and closing force of the gate; and the device can greatly save the horizontal pressure charging time so as to improve the working efficiency.
Description
Technical field
The present invention 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 through 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 up of panel and framework, support running gear, suspender water sealing part.Gate guide groove embedded part is made up 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, in the aggravation hoisting capacity, also causes the turnup even the damage of watertight rubber.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 objective of the invention is to overcome above-mentioned weak point, thereby a kind of water stop rubber protection device for flat steel gate is provided, in keying, can play the effect of protection watertight rubber and can reduce hoisting capacity.
According to technical scheme provided by the invention, water stop rubber protection device for flat steel gate comprises a body, watertight rubber, guide groove, and watertight rubber is arranged on the body; Characteristic is: also comprise hydraulic jack and water-filling equalizing valve, the water-filling equalizing valve is installed on the door body, the hydraulic jack flange is welded on the body framework; Said door body framework installs and fixes hydraulic jack through the hydraulic cylinder flange; Tailpiece of the piston rod at hydraulic jack is installed guide wheel, offers a hole on the said door body framework, fills 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, and watertight rubber is separated with the guide groove wall.
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 through bolt.
Said hole is a rectangle, is positioned at the watertight rubber outside.
Compared with present technology the present invention has the following advantages:
1, the present invention can well protect 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 apparatus of the present invention; 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.
Description of drawings
Fig. 1 is a structural front view of the present invention.
Fig. 2 is a structure vertical view of the present invention.
Fig. 3 is a hydraulic jack structural representation of the present invention.
Fig. 4 is a hydraulic jack segmentation flange structural representation of the present invention.
The specific embodiment
Following the present invention will combine the embodiment in the accompanying drawing to further describe:
Like 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 present invention is employed in water-filling equalizing valve 7 is installed on the body 1, and watertight rubber 2 is arranged on the body 1, and hydraulic jack flange 6 is welded on a body 1 framework; Install and fix hydraulic jack 4 through hydraulic cylinder flange 6 on the framework of said door body 1; Tailpiece of the piston rod at hydraulic jack 4 is installed guide wheel 5, offers a slot on said 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 said hydraulic jack 4, makes segmented to the flange on the hydraulic jack 49, with oil cylinder draw-in groove 8 mating reactions shown in Figure 3, is fixedly connected with flange on being welded on a body framework through bolt.This structure is more conducive to dismounting and safeguards.
Said hydraulic jack 4 is connected the implementation Long-distance Control through the anticorrosion flexible pipe of high pressure with hydraulic power unit on the platform.When gate hangs in guide groove when closing through 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 dam and cut off the water supply with the realization of combining closely of guide groove wall under hydraulic action.When gate need be opened, through 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 receive 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.
