Anti-freezing device at bottom of coal gondola car carriage

Abstract

The invention relates to an anti-freezing device for the bottom of a carriage of a coal gondola car, and discloses an anti-freezing device which supports a supporting bottom plate through a cam to generate up-and-down vibration and is matched with up-and-down movement of a piston to enable an air bag to expand and contract so as to repeatedly vibrate and fall off a frozen coal mine on the supporting bottom plate. The device is characterized in that a plurality of limiting plates are arranged on a fixed base at equal intervals, a cavity is formed by every two adjacent limiting plates, receding grooves are formed in the middles of the limiting plates, a plurality of connecting shafts are arranged on a fixed base, the connecting shafts are correspondingly located in the cavities, and transmission gears are arranged in the middles of the connecting shafts; the multiple transmission gears are connected through a transmission chain and form a transmission relation, the transmission chain is located in the receding groove, one set of cams are arranged on the connecting shaft, one set of cams are composed of at least four cams, the deflection angles of the cams in the same set are the same, and the deflection angles of the cams in the multiple sets are increased progressively.

Description

technical field [0001] The invention relates to an anti-freezing device for the bottom of a coal-transporting gondola car, relating to a device capable of preventing the bottom of a coal-transporting gondola car from freezing, and belongs to the technical field of coking coal dumping equipment. In particular, it relates to an anti-freezing device that vibrates up and down by supporting the support base plate with a cam, and cooperates with the vertical movement of the piston to make the airbag expand and contract, thereby repeatedly vibrating and falling off the frozen coal mine on the support base plate. Background technique [0002] At present, in order to avoid the coal dust in the gondola compartment of the coal train, the coal mines in the gondola car are generally sprayed and watered.

Problems solved by technology

[0002] At present, in order to avoid the coal dust in the gondola compartment of the coal train, the coal mines in the gondola car are generally sprayed and watered. However, due to the generally low temperature in winter, the bottom of the gondola compartment of the coal train is prone to coal freezing. The coal sticks and coagulates at the bottom of the carriage, so that the coal mine near the bottom of the car cannot fall normally when unloading coal, which affects the coal unloading work. Traditionally, operators usually need to use excavators to clean it, or manually use wind to clean it. Pickaxes and shovels are used to hammer and break frozen blocks, which is time-consuming and labor-intensive, and the crushing efficiency is low. However, the notification number CN208594787U in the prior art discloses a thawing shed for a train gondola car. The technical solution is: on both sides of the train track Build color steel tiles on and above the train track. The color steel tiles on one side of the train track are fixed on the column foundation. There is a curtain between the color steel tiles on the other side of the train track and the ground where the train track is located. The color steel tiles and hanging curtains constitute a thawing shed. There are multiple steam pipes in the thawing shed. There are a number of steam nozzles connected to the steam pipes on both sides of the train track in the thawing shed. The jet direction of the steam nozzles is Facing the side and bottom of the train, but the steam thawing method will firstly cause the moisture content in the coal mine to be too high and affect the subsequent treatment, and secondly, it will leave a large amount of water vapor on the floor of the carriage after thawing, and the thawed coal needs to be removed immediately Dumping to avoid secondary freezing after thawing
