Abstract
The utility model relates to a cover plate, in particular to a dam hoist chamber lifting hole plugging cover plate for lifting the ponding dam radial gate, comprising a lifting hole frame, a plugging cover plate arranged on the lifting hole frame, and a wire rope which is arranged in the lifting hole frame and used for lifting the dam radial gate; one side of the sealing cover plate is provided with a wire rope groove; the two sides of the lifting hole frame are provided with fixing angle irons; a support shaft is arranged between the fixing angle irons, and the support shaft is sleeved with a sleeve and a spring; a movable cover plate is fixedly connected under the sleeve and is also provided with a wire rope groove; and a roller is arranged between the sleeves by a connecting shaft. Compared with the prior art, the utility model can plug and open the lifting hole during the lifting process of the hoist radial gate, and has the advantages of convenient operation, simple structure, low manufacturing cost, no damage on the device and high safety.
Description
Technical field
The utility model relates to a kind of cover plate, specifically a kind of lower storage reservoir dam arc gantry crane when dress dam hoist chamber lifting hole(eyelet) shutoff cover plate that is used for.
Background technology
Lifting hole(eyelet) when the hoist chamber of present lower storage reservoir dam arc door lifts is difficult to by shutoff, in the long-play process of headstock gear, dust is easy to enter, and causes the headstock gear indoor environment relatively poor, in case dust enter machinery and electric in, its application life can be shortened, winter, room temperature was lower, also can influence headstock gear operation, summer water evaporation, moist in the hoist chamber, also can influence the operation of a machine.
The utility model content
The utility model is at the deficiency of hoist chamber's lifting hole(eyelet) portion sealing in the prior art, provides a kind of simple in structure, can finish the dam hoist chamber lifting hole(eyelet) shutoff cover plate of lifting hole(eyelet) shutoff in headstock gear arc door motion process.
Realize that above-mentioned purpose by the following technical solutions: a kind of dam hoist chamber lifting hole(eyelet) shutoff cover plate, comprise the lifting hole(eyelet) framework, place the closed cover on the lifting hole(eyelet) framework and place lifting hole(eyelet) framework inside, be used to lift the wire rope of dam arc door, a side of described closed cover is provided with the wire rope draw-in groove; Fixedly angle bar is equipped with in described lifting hole(eyelet) framework both sides, and fulcrum fixedly is housed between the angle bar, is set with sleeve pipe and spring on this fulcrum, is connected with removable cover below the sleeve pipe, also is provided with the wire rope draw-in groove on this removable cover; With connecting axle cylinder is housed between the sleeve pipe.
Compared with prior art, the utility model is in the lifting process of headstock gear arc door, and the shutoff that just can finish lifting hole(eyelet) is with unlimited, and easy to operate, simple in structure, cost of manufacture is low, does not damage equipment, and is safe.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing 1, in the present embodiment, the circular arc dotted line is the movement locus of wire rope 9 among the figure.This dam hoist chamber lifting hole(eyelet) shutoff cover plate, a side of its closed cover 1 is provided with two semicircular wire rope draw-in grooves 3, two groups of fixedly angle bar 10 are equipped with in described lifting hole(eyelet) framework both sides, all be fixed on the closed cover 1 and lifting hole(eyelet) framework 11 on.Fulcrum 2 fixedly all is being housed between the angle bar 10, and the middle part of fulcrum 2 all is set with sleeve pipe 8, on the fulcrum 2 of these sleeve pipe 8 bottoms, also is set with spring 7.The soffit of sleeve pipe 8 is welded with rectangle removable cover 4, also is provided with semicircular wire rope draw-in groove 3 on this removable cover 4.Between two sleeve pipes 8 connecting axle 6 is housed, is set with cylinder 5 on this connecting axle 6, the top edge of this cylinder 5 is a little more than the top edge of removable cover 4.Wire rope 9 places between closed cover 1 and the removable cover 4.
Operating principle of the present utility model is: because on headstock gear in the ascending, descending process, the angle between the wire rope 9 changes, i.e. and same point on the wire rope 9, when vertical displacement taking place changing, variation has also taken place in horizontal movement.In its lifting process, wire rope 9 rubs with cylinder 5, cause cylinder 5 occurred level displacement when rolling, thereby under the drive of connecting axle 6, sleeve pipe 8 compression or loosen extruding to spring 7, horizontal movement has taken place in the removable cover 4 that is fixed in sleeve pipe 8 soffits, has realized the shutoff of lifting hole(eyelet) and opens wide.When removable cover 4 is in the complete closed position, owing to be equipped with wire rope draw-in groove 3 on closed cover 1 and the removable cover 4, make wire rope 9 place in this draw-in groove, all the other position sealings.
The two ends of cylinder 5 are made circular-arc, and its surface finish is smooth, guarantee that wire rope 9 rises, in the decline process, the lubrication oil on the wire rope 9 is unlikely to come off, and also can avoid damage equipment.
