Toothed cable bucket conveyor

Abstract

The invention discloses a toothed cable bucket conveyor comprising racks, a closed box with a feeding port and a discharging port, driving devices fixed to the racks at the two ends, driving wheels mounted on output shafts of the driving devices and located in the two ends of the closed box. A plurality of equidistantly-arranged toothed cable tooth block assemblies are fixed to two parallel closed-loop type steel wire ropes, and a plurality of first grooves in the outer circumferences of the driving wheels are engaged with the toothed cable tooth block assemblies on the two parallel closed-loop type steel wire ropes. Hopper support wheels which are in rolling fit with support wheel bottom plates of the racks are rotatably connected to hoppers through shafts, and the diameter dimension of the hopper support wheels is larger than the height dimension of the hoppers; and the middle portions of the bottoms of tooth blocks in the toothed cable tooth block assemblies in the length directionare provided with anti-deviating structures which are matched with anti-deviating tracks fixed to the middles in the transverse directions of the racks and used for preventing deviating. By means of the conveyor, special guide rails do not need to be additionally arranged, the hoppers turn smoothly and stably, wear is small, the hopper anti-deviating performance is good, and the closed-loop steelwire rope stress negative influences are small.

Description

technical field [0001] The invention relates to the technical field of conveying equipment for powdery or granular materials, in particular to a toothed cable bucket conveyor. Background technique [0002] The conveying equipment for powdery or granular materials in the prior art, such as conveyors used for coal ash, coal slag or pulverized coal transportation in power plants, sometimes has a long conveying distance from the head end to the end, such as hundreds of meters or even thousands of meters , the height is sometimes higher, such as 5 to 30 meters, and it is also required that this type of equipment can operate normally in a dusty environment. [0003] But the operation condition of the tooth cable bucket conveyor of prior art is not ideal, also there is following deficiency: [0004] 1. The problem of blanking in the gap between hoppers in series and the return of accumulated material on the bottom plate of the closed box and the rapid processing of materials at th...

Problems solved by technology

[0003] But the operation condition of the tooth cable bucket conveyor of prior art is not ideal, also there is following deficiency:

In this way, two guide rails on the upper and lower layers with high precision must be set up, and the matching accuracy of the guide rails and the hopper support wheels must be high, which not only increases the material and installation costs of the high-precision guide rails, but also makes the equipment at both ends. When turning, if the guide rail or the hopper supporting wheel is slightly deformed or the matching between the hopper supporting wheel and the shaft is slightly worn, the smoothness and stability of the turning will be negatively affected, and even affect the normal operation of the equipment; due to the hopper supporting wheel The diameter is relatively small, and the speed of the hopper support wheel is relatively fast. In actual operation, the shaft of the hopper wears a lot, which increases the failure rate of the equipment, thereby shortening the service life of the equipment.

[0006] 3. The cables of the toothed cable bucket conveyor, such as the closed-loop steel wire rope, are all in the transverse middle of the hopper, while the anti-deviation structure or correction structure of the hopper, that is, the correction wheel and the limit guide rails that cooperate with each other, are all in the hopper on both sides of the hopper On the outside of the support wheel, in actual operation, the friction between the anti-deflection wheel and the limit guide rail has a negative impact on the force of the wire rope, that is, the reaction force and vibration force are increased, and the gear block assembly of the toothed cable of the closed-loop wire rope is pressed up and down. Bolts often loosen, which causes great troubles to the normal operation and use of the equipment; in addition, each hopper needs to be equipped with two anti-deflection wheels on both sides, and due to the rigidity, the diameter of the anti-deflection wheels needs to be larger. Large, the anti-deflection structure has a lot of consumables, and the cost of materials, installation and maintenance is relatively high

[0007] However, during the actual operation of the equipment, the anti-deviation structure sometimes contradicts and conflicts with the anti-deviation function or correcting function of the anti-deviation wheel or correcting wheel and the limit guide rail, thus increasing the accuracy of the deviation. The negative effect of the closed-loop wire rope is the reaction force, which objectively increases the failure rate of the equipment
