Abstract
The invention relates to a closing mechanism of a hydroelectric dam flood discharge valve hoist chamber, in particular to an automatic opening and closing mechanism for wire rope holes of a floodgate. The automatic opening and closing mechanism comprises a cover plate framework fixed at a reserved-hole part of steel wire ropes, a movable cover plate controlled to open and close through a reset spring is mounted on the cover plate framework, and a roller in friction fit with the steel wire ropes is mounted on the movable cover plate. When uplifted, the floodgate is pushed to move backwards through angle power produced in winding of the iron wire ropes, and the movable cover plate is driven to open; when the floodgate drops, the steel wire ropes return to the initial positions, and the movable cover plate and the roller are enabled to integrally return to the state that reserved holes of the steel wire ropes are closed by the aid of the reset spring. The automatically opening and closing mechanism can be opened and closed freely and is safe and reliable, secondary operation is omitted, opening and closing operations of the floodgate is unaffected; components of the mechanism are low in manufacturing cost and simple in manufacturing.
Description
Technical field
The present invention relates to the closing means of Hydropower Dam sluice hoist chamber, specifically the automatic on/off mechanism of a kind of floodgate wire rope hole portion.
Background technology
At present, Hydropower Dam sluice headstock gear all designs indoor.The lifting wire rope of floodgate will be connected with headstock gear through hoist chamber, and hoist chamber is provided with wire rope lift span.Wire rope vary within wide limits all around during due to lift gate, therefore needs the wire rope lift span of reserved large-size.Existing wire rope preformed hole, does not substantially install closing means and is open state, and winter temperature is low, and summer, aqueous vapor evaporation was risen, and caused and opened and closed indoor humidity, affected the application life of headstock gear; What have installation closing means is only also a simple cover plate, open by manpower transport, and bad sealing, easily operate miss, brings undesirable element to personnel and device security.
Summary of the invention
The technical problem to be solved in the present invention is, a kind of floodgate wire rope hole automatic on/off mechanism is provided, and makes floodgate not when lifting by this mechanism, can effective sealing wire rope preformed hole; When floodgate lifting, can automatically adjust with the swing of wire rope the opening size of wire rope preformed hole, and not affect the lifting of floodgate.
The present invention solves described problem, and the technical scheme of employing is:
A kind of floodgate wire rope hole automatic on/off mechanism, comprises the cover plate framework that is fixed on wire rope preformed hole portion, on described cover plate framework, the removable cover being opened and closed by back-moving spring control is housed, and the cylinder with wire rope frictional fit is housed on described removable cover.
Adopt the present invention of technique scheme, compared with prior art, its beneficial effect is:
When this mechanism mentions at floodgate, rely on wire rope roll around time angle powered cylinder move backward, drive removable cover open; When floodgate falls, wire rope is got back to initial position, utilizes back-moving spring to make removable cover and cylinder entirety revert to sealing wire rope preformed hole state.This mechanism opening, close freely, safe and reliable, without secondary operation, do not affect floodgate and open and close operation.Each assembly low cost of manufacture of mechanism, makes simple.
As preferably, the present invention further technical scheme is:
In the middle of described cover plate framework, there is a rectangle perforate through wire rope, above described rectangle perforate, by two ends fixed bearing, a pair of guide peg is housed, on each described guide peg, be slidably fitted with respectively guide pin bushing and back-moving spring thereof; Described removable cover is fixedly connected with described guide pin bushing by gripper shoe, and when back-moving spring holds out against guide pin bushing, removable cover covers rectangle perforate; The roller bearing portion at described cylinder two ends is connected with described guide pin bushing, cylinder be positioned at described removable cover top and with wire rope frictional fit, extruding drum when wire rope pulling floodgate, drives after guide pin bushing and removable cover entirety cylinder and moves and open rectangle perforate.
Described removable cover front end edge is provided with the groove embedding for wire rope, and when wire rope embeds described groove, removable cover tightly covers rectangle perforate.
Brief description of the drawings
Fig. 1 is the structural representation of the embodiment of the present invention under floodgate closed condition;
Fig. 2 is the structural representation of the embodiment of the present invention under floodgate lifting state;
In figure: cover plate framework 1, fixed bearing 2, guide peg 3, guide pin bushing 4, gripper shoe 5, back-moving spring 6, removable cover 7, cylinder 8, groove 9, wire rope 10, rectangle perforate 11.
Detailed description of the invention
The embodiment providing below in conjunction with accompanying drawing describes the present invention in detail.The present embodiment is only for technical scheme of the present invention is more clearly described, and not limits the scope of the invention.
Referring to accompanying drawing, the floodgate wire rope hole automatic on/off mechanism described in the present embodiment, entirety is fixed on the wire rope preformed hole portion of hoist chamber by its cover plate framework 1.
In the middle of cover plate framework 1, there is a rectangle perforate 11 through wire rope 10, above rectangle perforate 11, by the fixed bearing 2 at two ends, a pair of guide peg 3 is housed, on each guide peg 3, be slidably fitted with respectively guide pin bushing 4 and back-moving spring 6 thereof; On guide pin bushing 4, be fixed with gripper shoe 5, gripper shoe 5 lower ends are fixedly connected with removable cover 7, and when back-moving spring 6 holds out against guide pin bushing 4, removable cover 7 covers rectangle perforate 11; Bearing assembly is equipped with in gripper shoe 5 upper ends, removable cover 7 front end top positions are provided with cylinder 8 by this bearing assembly, cylinder 8 and wire rope 10 frictional fit, extruding drum 8 when wire rope 10 lifts floodgate, drives after guide pin bushing 4 and removable cover 7 entirety cylinder 8 and moves and open rectangle perforate 11.
Removable cover 7 front end edges are provided with the groove 9 embedding for wire rope 10, and when floodgate falls, wire rope 10 is got back to initial position, without squeezing action, now utilize the elastic force promotion guide pin bushing 4 of back-moving spring 6 to drive removable cover 7 to return closed state to cylinder 8.Wire rope 10 will make removable cover 7 tightly cover rectangle perforate 11 in embedding groove 9.
Above-mentioned floodgate wire rope hole automatic on/off mechanism repeatedly uses by scene, and open, close freely, to wire rope preformed hole good sealing effect, and good looking appearance.
