Background

The railway gondola car is the railway transportation equipment of enterprise transportation goods and materials, and the gondola car that metallurgical enterprise used mainly is transportation coal, mineral substance, and the gondola car is provided with a plurality of wicket, and a plurality of wicket are installed respectively in the both sides of gondola car, the loading and unloading of the goods and materials of being convenient for, and wicket is the device of closing the wicket, prevents that the wicket from closing not tight and leading to the goods and materials leakage loss of loading. Each small door is provided with two door belts and two hasp locking devices, the hasps are tightly pressed on the door belts to realize the locking function, a round sleeve is arranged in each hasp and is fixed on the hasp seat through a bolt inserted into the round sleeve, a common gasket is arranged between the round sleeve and the bolt, the installation and the use of the hasps are met, and the hasps rotate by taking the round sleeves as shafts. However, the coal and mineral substances loaded on the gondola car of the metallurgical enterprise have high corrosivity, and the round sleeve and the gasket of the small door hasp of the gondola car are mutually independent and have gaps, so that the inner part and the outer part of the gasket of the hasp sleeve are corroded easily, the hasp loses the function of locking the small door, even the hasp falls off and is lost, and the small door is opened to cause the accident of material leakage.

At present, the maintenance period of the railway open wagon is mainly divided into two types, one is first repair every year and is called section repair, and the other is first repair every five years and is called overhaul repair. The maintenance of the small door hasp of the open wagon belongs to the field of overhaul, but the hasp cannot be maintained for a period of section maintenance due to the loading of coal and mineral substances, the sleeve gasket of the hasp is corroded, and the hasp directly falls off in severe cases. There is therefore a need for an improved arrangement for a pocket for a door hasp.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims at providing a railway spacious door hasp sleeve gasket structure, with interior round cover and outer gasket fixed connection, and both spaces are minimum, have effectively solved the easy problem of corroding of present hasp sleeve gasket junction.

The above technical object of the present invention can be achieved by the following technical solutions:

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

As shown in fig. 1-2, the utility model provides a railway spacious door hasp cover pad structure, include the cover pad 1 with the through-hole adaptation of hasp 3, cover pad 1 includes interior circle cover 12 and outer gasket 11, the outer end side of interior circle cover 12 is provided with annular step 14, the annular step 14 outside is provided with the external screw thread, the interior bottom surface of outer gasket 11 is provided with the connecting portion 13 with the cylinder of annular step 14 adaptation, the inner wall of connecting portion 13 is provided with the internal thread with the adaptation of annular step 14, and connecting portion 13 and the 14 threaded connection of annular step make interior circle cover 12 and outer gasket 11 fixed connection, preferably, the external diameter of connecting portion 13 is the same with the biggest external diameter of interior circle cover 12.

It should be noted that, in interior circle cover 12 was the through-hole of embedding hasp 3, interior circle cover 12 is whole to be the drum shape, and the biggest external diameter of interior circle cover 12 is the same with the through-hole internal diameter, and the degree of depth that highly is not more than the through-hole generally of interior circle cover 12 the utility model discloses, the outer end side department of interior circle cover 12 is provided with annular step 14, forms and dodges the vacancy, and when connecting portion 13 and the 12 step threaded connection of interior circle cover of outer gasket 11, connecting portion 13 played the effect of filling this vacancy of dodging, made the through-hole of hasp 3 cover interior circle cover 12 and connecting portion 13 completely, at this moment, outer gasket 11 exposes in the outside, nevertheless because outer gasket 11 and connecting portion 13 are integrated into one piece, consequently, the junction of outer gasket 11 and interior circle cover 12 is covered, not contacted with by the colliery material, reduces the possibility of being corroded.

As shown in figure 1, a hasp seat 2 is fixed on the side surface of the open wagon, a sleeve gasket 1 formed by fixedly connecting an inner circular sleeve 12 and an outer gasket 11 is plugged into a through hole of a hasp 3, then a fixing bolt 4 penetrates through the sleeve gasket 1 to be connected with the hasp seat 2, the hasp 3 is limited to be separated outwards, the hasp 3 rotates by taking the sleeve gasket 1 as a shaft, and after the hasp 3 is clamped with a clamping seat 5 on the other side, a small door 6 of the open wagon is closed.

Further, the bottom surface of the annular step 14 is provided with a first annular protrusion 15, the bottom surface of the connecting portion 13 is provided with an annular groove 17 matched with the first annular protrusion 15, and when the inner circular sleeve 12 is connected with the outer gasket 11, the first annular protrusion 15 is embedded into the annular groove 17.

Specifically, first annular protrusion 15 plays the effect of further blockking corrosive substance, because interior round cover 12 is threaded connection with outer gasket 11, when corrosive liquids infiltrates the junction, still probably make the interior outer corrosion of the junction of interior round cover 12 and outer gasket 11, the utility model discloses an gomphosis of first annular protrusion 15 and annular groove 17 blocks corrosive liquids outside, ensures that the threaded connection department of interior round cover 12 and outer gasket 11 is not corroded.

Preferably, the annular step 14 is provided with a corrosion-resistant layer, which is located outside the first annular projection 15 and is a soft material.

When the annular step 14 is in threaded connection with the connecting part 13, the soft corrosion-resistant layer is extruded to fill all gaps at the connecting part of the annular step 14 and the connecting part 13, so that corrosive liquid is prevented from permeating better.

Further, the outer bottom surface of the gasket is provided with a second annular bulge 16, the inner diameter of the second annular bulge 16 is greater than or equal to the outer diameter of the head of the fixing bolt 4, and the height of the second annular bulge 16 is smaller than the thickness of the head of the fixing bolt 4. In order to prevent that fixing bolt 4 and outer gasket 11 contact department also permeate corrosive liquid, set up second annular bulge 16 in the outer bottom surface of outer gasket 11, play the effect that blocks corrosive liquid, second annular bulge 16 highly needs to be less than the thickness of fixing bolt 4 head, does not influence dismouting fixing bolt 4.

The utility model discloses an outer gasket 11 and interior round cover 12 fixed connection, and the space is minimum, and the junction of outer gasket 11 and interior round cover 12 is covered by the hasp, blocks effectively that corrosive substance invades inside the cover fills up 1, has solved the problem of 1 inside corrosion of hasp cover pad.
