Description

Hopper device for toothed cable bucket conveyor

Technical Field

The utility model relates to a powdered or granular material conveying equipment technical field specifically says a hopper arrangement for tooth cable bucket conveyor.

Background

In the prior art, powdered or granular substance conveying equipment such as a coal ash, cinder or pulverized coal conveying conveyor for a power plant has a long conveying distance from a head end to a tail end, such as hundreds of meters or even thousands of meters, and has a high height, such as 5-30 meters, and the equipment is required to normally operate in an environment with more dust.

However, the operation condition of the prior art toothed-cable bucket conveyor is not ideal, and the following defects exist:

in order to ensure that the process of the hopper from the material conveying state to the return state or from the return state to the material conveying state, namely the turning process, is smooth, the hopper riding wheels on two sides of the hopper body of the hopper device in the prior art must be matched with a special guide rail for use and objectively require that the diameter size of the riding wheels is smaller than the height size of the hopper body. Therefore, two guide rails with higher precision are required to be arranged, and the matching precision of the guide rails and the riding wheels is required to be high, so that the material and the installation cost of the high-precision guide rails are increased, and when the states of two ends of the equipment are converted, the guide rails or the hopper riding wheels are slightly deformed or the matching parts of the hopper riding wheels and the shafts are slightly worn, the conversion smoothness and the stability of the equipment are negatively influenced, and even the normal operation of the equipment is influenced; because the diameter of the hopper supporting roller is relatively small, the rotating speed of the supporting roller is relatively high, the abrasion of a shaft of the hopper device is large in actual operation, the failure rate of the equipment is increased, and the service life of the equipment is shortened.

In actual operation, friction between the anti-deviation wheel and the limiting guide rail generates negative influence on stress of the steel wire rope, namely, increases reaction force and vibration force, and screws in a gear tooth block assembly of the steel wire rope are often loosened when the screws are pressed up and down, so that great trouble is caused to normal operation and use of equipment; in addition, each hopper device needs to be provided with two anti-deviation wheels at two sides, the diameter of each anti-deviation wheel needs to be larger due to the rigid relation, the anti-deviation structure consumes more materials, and the material cost and the installation and maintenance cost are higher.

In the actual operation of the equipment, the guide action of the hopper supporting wheel and the guide rail sometimes conflicts and conflicts with the deviation prevention action of the deviation prevention wheel and the limiting guide rail, so that the negative influence, namely the reaction force, on the stress of the steel wire rope is increased, and the fault rate of the equipment is objectively increased.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a need not establish special guide rail, hopper arrangement turn smoothly and stably and hopper riding wheel and the relative little hopper arrangement that is used for tooth cable bucket conveyor of axle wearing and tearing.

The technical solution of the utility model is that, a hopper arrangement for tooth cable bucket conveyor is provided, be open-ended hopper body including the top side, the roll cooperation is connected with the hopper body rotation at the hopper riding wheel warp beam in the frame, the diameter size of hopper riding wheel be greater than the height dimension of hopper body.

After the structure above adopting, the utility model discloses a hopper arrangement for tooth cable bucket conveyor has following advantage: need not to set up special riding wheel guide rail in the closed box, when hopper body is unloaded the back return stroke or the in-process that hopper body entered into the charged state from the unloaded state is also called the turn in-process, because the diameter size of hopper riding wheel is greater than the height dimension of hopper body, the hopper body does not need accurate location, the hopper riding wheel can directly move on the riding wheel bottom plate of frame promptly, saved respectively two high-accuracy guide rails of upper strata and lower floor, material cost and installation cost have both been practiced thrift, when making equipment at the mode conversion at both ends again, make hopper arrangement's operation smooth and easy and stable, and then guarantee the normal operating of whole equipment. In addition, under the condition of running for the same distance, the rotating speed of the hopper supporting wheel is relatively slow due to the increase of the diameter of the hopper supporting wheel, and the abrasion of a shaft of the hopper device is small in actual running, so that the failure rate of the equipment is reduced, and the service life of the equipment is prolonged.
