Description
Technical Field
The utility model relates to a mechanical equipment, especially an improved mine car.
Background
20m bottom discharge mine car is the novel ore loading equipment who commonly uses in the mining, and 8 personal font suspension rubber masses are installed to this type of mine car design, are formed by 4 layers of steel sheet and 3 layers of rubber bonding. The suspension rubber blocks are respectively arranged on the left side and the right side of 4 axle boxes of the mine car and are outwards fixed from the inside of the axle boxes by utilizing 1M 10 hexagon socket head cap bolts, and the herringbone rubber blocks have the main functions of supporting and buffering the whole mine car body and playing a certain steering role when the mine car bends in by matching with a connecting coupler knuckle of a mine workshop.
However, if oversize ore larger than 1.2m 1.6m is mixed in raw ore in the use process of the mine car, the impact on the bottom plate of the whole mine car is large, and an unbalance loading phenomenon exists in the ore loading process, so that the problem of breakage of a herringbone suspension rubber block screw rod and a fixed support connecting plate outside a wheel set axle box is easily caused, the herringbone suspension rubber block slides downwards after being damaged, a carriage sinks, the safety distance between the axle box and a mine wheel bottom plate is shortened, friction between the bottom plate of the mine car and the wheel rim is caused, the mine car turns under the condition of heavy-duty car, wheels are easily blocked, and the derailment accident of the mine car is caused.
Disclosure of Invention
The utility model aims at improving the problems of the mine car, prolonging the service life of the mine car and improving the safety of the mine car.
The novel mine car with the buffer device comprises a mine car connecting coupler knuckle, herringbone suspension rubber blocks, mine car axle boxes, mine car wheels, outer hexagon bolts, wheel supporting plates and the buffer device, and is characterized in that the herringbone suspension rubber blocks are fixed on the left side and the right side of the four mine car axle boxes, the herringbone suspension rubber blocks on each side are fixed by two outer hexagon bolts, and the upper end and the lower end of each herringbone suspension rubber block are respectively provided with one buffer device; the buffer device is a plate with a three-layer structure, the upper layer and the lower layer are steel plates, the middle interlayer is made of boiled glue and is bonded, screw holes are formed in two ends of the lower layer of steel plate, and the buffer device is fixed on a bottom plate of the mine car through bolts and nuts.
The utility model discloses a mine car has solved the chevron shape suspension of existing use and has glued the piece under intact state, though can ensure the buffering of mine car automobile body and turn to the problem, but in the use, receives the damage easily, and maintenance work volume is big, drawback that cost of maintenance is high.
The novel buffer device can effectively increase the supporting area of the whole tramcar carriage, and can absorb and filter the impact force of a large block to the bottom plate of the tramcar to the maximum extent in the process of loading. The mine car has a stable structure, is not easy to deform, is not easy to damage, is durable, and does not need to increase too much investment.
The change of chevron shape suspension rubber block mounting means to and install buffer additional after, can ensure that axle box and mine car bottom plate remain 50 mm's distance throughout, make the average life extension of mine car, reduced the time of maintenance, reduced cost of maintenance.

The mine car connecting hook bolt comprises a mine car connecting hook tongue 1, a herringbone suspension rubber block 2, a mine car axle box 3, a mine car wheel 4, an outer hexagon bolt 5, a wheel supporting plate 6, a buffer device 7, a screw hole 8, a mine car bottom plate 9, an inner hexagon bolt 10, a steel plate 11, a glue 12, a bolt and a nut 13.
Detailed Description
Example 1: the novel mine car with the buffer device comprises a mine car connecting coupler knuckle 1, a herringbone suspension rubber block 2, a mine car axle box 3, mine car wheels 4, outer hexagon bolts 5, a wheel supporting plate 6 and a buffer device 7.
The herringbone suspension rubber blocks 2 are fixed on the left side and the right side of four mine car axle boxes 3, the herringbone suspension rubber blocks 2 on each side are fixed by two outer hexagon bolts 5, and the upper end and the lower end of each herringbone suspension rubber block are respectively provided with one.
The buffer device 7 is a three-layer plate, the upper layer and the lower layer are steel plates 11, the middle interlayer is made of boiled glue 12, and the two layers are bonded. Screw holes 8 are arranged at two ends of the lower steel plate, and the buffer device 7 is fixed on a bottom plate 9 of the mine car through bolts and nuts 13.
The middle interlayer is provided with two blocks of boiled glue, the middle block is square, and the periphery is annular.
The specification of the outer hexagon bolt 5 is M12.
The thickness of the buffer device is 49mm, the length is 362mm, and the width is 130 mm.
The utility model discloses well adoption outer hexagon bolt glues the piece from the fixed chevron shape suspension in outside, adopts interior hexagon bolt from the inside external fixation of axle box relatively, and it is relatively convenient to install, and is difficult for the rupture.
After the buffer device is additionally arranged on the bottom plate of the mine car, the distance between the axle box and the bottom plate of the mine car is kept at 50mm all the time, the supporting area of the whole carriage of the mine car is effectively increased, and in the process of ore loading, the impact force of a large block on the bottom plate of the mine car can be absorbed and filtered to the greatest extent.
