Swing arm drive device for spraying antifreeze on coal-carrying train

Abstract

The invention relates to a swing arm drive device for spraying antifreeze on a coal-carrying train, belonging to the field of machinery design. The swing arm drive device for spraying the antifreeze on the coal-carrying train is characterized by being of a structure of changing a shaft diameter by means of shaft sleeves and arranging a drive mechanism in the middle of a shaft, and the swing arm drive device comprises a square upright, a clamp device, a slewing mechanism, a driving mechanism, a stop block, an upper arm assembly and a lower arm assembly. One shaft sleeve is designed at each end of the shaft of the swing arm drive device, and the drive mechanism is arranged in the middle area of a rotating shaft, thus the distance between an upper support plate and a lower support plate in a limited space is increased, and the force applied by the supported swing arm to the rotating shaft is reduced. According to the invention, the diameter of the rotating shaft is changed by means of the shaft sleeves, and the position of the drive mechanism is rationally arranged, therefore volume and weight of the swing arm drive device are reduced, cost is saved and field installation is convenient. The swing arm drive device for spraying the antifreeze on the coal-carrying train has the characteristics of lower horizontal rotating speed, smaller rotating driving torque and strong radial carrying capacity at two ends of the rotating shaft, is in particular suitable for support and horizontal rotating drive to the swing arm for spraying the antifreeze on the coal-carrying train.

Description

technical field [0001] The invention relates to a swing arm drive device for antifreeze spraying of coal trains, belonging to the field of mechanical design, and in particular to a device capable of supporting and driving the antifreeze spray swing arms of coal trains to rotate horizontally. Background technique [0002] The current high-efficiency coal production methods all use fully mechanized mining equipment. During the mining process, water spraying is required to reduce dust and control the high temperature of the equipment. During the deep processing of coal, water is used to wash the ore, and a large amount of water is used in the process of coal washing. These reasons cause coal to contain a large amount of moisture. The railway is the main channel for coal transportation in my country. According to statistics, the railway transportation volume of hydrous coal is close to more than 50% of the total transportation volume. The weather in northern my country is cold ...

AI Technical Summary

Problems solved by technology

Due to the provisions of the national standard "Standard Gauge Railway Building Limits" (GB146.2-83) on the basic building limits of railways, antifreeze spraying equipment can only be installed at a higher position, resulting in high-level spraying of antifreeze, which is difficult to accurately control In the spraying area, part of the antifreeze is sprayed outside the compartment, especially when the wind is strong, a large amount of antifreeze floats outside the compartment, which greatly reduces the coverage of the antifreeze in the compartment, wasting a lot of antifreeze, and sprayed outside the compartment Antifreeze pollutes the environment

[0005] Patent No. ZL201020127246.2 swing arm lifting antifreeze spraying device, the lifting mechanism adopts the vertical swing arm method, because the loading area of ​​some coal preparation plants is a ceiling building structure, which limits the upward space of the spraying arm, so it cannot be used. The device described in the patent

The patent No. ZL200910074337.6 is a swing-arm type antifreeze spraying device for a two-lane coal-carrying train. Due to structural design, the mechanism is large in size and difficult to install and disassemble. The force is very large, so the strength and rigidity of the support of the device are very high, which limits the application in some occasions
