Follow-up device of coal mine fully-mechanized coal winning machine belt support

Abstract

A follow-up device of a coal mine fully-mechanized coal winning machine belt support is characterized in that: the number of upper supports is two, both ends of an i-steel support beam (1) are fixed on two upper ends of the two upper supports, lower ends of the upper supports are provided with a connecting plate (5), the lower part of the connecting plate (5) is connected with the middle part of a shaft (7) through a damping mechanism, both ends of the shaft (7) are fixedly connected with the middle part of two fender plates (8), a follow-up of a wheel (9)-formed support is respectively arranged between two ends of each fender plate (8), and automatic adjustment shock absorption of the support is formed by the shaft (7), a damping mechanism and two wheels (9). The upper support body is manufactured by i-steel, a strong and stable support structure is formed, the damping mechanism effectively prevents the vibration phenomenon at rail joints during marching of the machine, and through the follow-up of the wheel (9)-formed support between the two fender plates, safety production of fully-mechanized coal winning machine belt support is improved.

Description

【Technical field】 [0001] The invention relates to a belt bracket, in particular to a follower device for a belt bracket of a fully mechanized excavator in coal mines. 【Background technique】 [0002] As known, fully mechanized roadheader is the abbreviation of comprehensive mechanized roadheader, which is a kind of comprehensive mechanized equipment that integrates multiple functions of tunneling, rock loading, coal transportation, even support, and nail road; after using mechanized roadheader in coal mine Compared with the previous tunneling technology of drilling and blasting, the tunneling progress can be increased by more than 30 times. While the existing fully-mechanized excavator brings efficiency improvements, the belt conveyor support cannot move forward synchronously with the excavation of the fully-mechanized excavator. It is necessary to use manual propulsion to move the bracket forward. However, due to environmental restrictions and technical constraints, the brac...

Problems solved by technology

[0002] As known, fully mechanized roadheader is the abbreviation of comprehensive mechanized roadheader, which is a kind of comprehensive mechanized equipment that integrates multiple functions of tunneling, rock loading, coal transportation, even support, and nail road; after using mechanized roadheader in coal mine Compared with the previous tunneling technology of drilling and blasting, the tunneling progress can be increased by more than 30 times. While the existing fully-mechanized excavator brings efficiency improvements, the belt conveyor support cannot move forward synchronously with the excavation of the fully-mechanized excavator. It is necessary to use manual propulsion to move the bracket forward. However, due to environmental constraints and technical constraints, the bracket of the belt conveyor cannot fluctuate greatly.
