A fully mechanized excavator foam dust suppression device installation mechanism

Abstract

The invention provides an installation mechanism of a roadheader foam dust removal device. The installation mechanism comprises a lower hoop, a lower clamping plate, a two-way lead screw, an upper clamping pate, a fixed frame, an upper hoop, a lower support plate, an upper support plate, a sliding groove and a moving clamping plate; the fixed frame is fixed on the left end face of the upper hoop;the two-way lead screw is fixed in the fixed frame; the upper clamping plate is connected with the two-way lead screw through a ball nut I; the ball nut I is assembled at a position of the upper portion of an annular side face of the two-way lead screw; the lower clamping plate is connected with the two-way lead screw located at the lower side of the lower hoop through a ball nut II, and the stability of the mechanism installation is improved; the lower clamping plate is fixed on the upper side of an annular side face of the upper hoop, and the buffer function of the mechanism is realized by the design; the moving clamping plate is fixed on the upper end face of a sliding block, and the design facilitates the installation of the foam dust removal device; and the installation mechanism of the roadheader foam dust removal device is good in stability, convenient to operate, long in service life, and high in reliability after installing.

Description

Technical field [0001] The invention is an installation mechanism of a foam dust suppression device for a comprehensive excavator, which belongs to the field of coal mining equipment. Background technique [0002] In the prior art, the foam dust suppression device is installed on the fixed bolts of the cantilever section of the comprehensive excavator and the reducer. Because the roadway rock is relatively hard, the cutting arm vibration of the comprehensive excavator during tunneling is relatively large, and the fixed bolt may be caused after installation. In the prior art, the foam dust reduction device is easily damaged by long-term vibration during use, and the service life is shortened; in the prior art, the installation and operation of the foam dust reduction device It is cumbersome, time-consuming and laborious, so a foam dust reduction device installation mechanism of a comprehensive excavator is needed to solve the above problems. Summary of the invention [0003] In vi...

AI Technical Summary

Problems solved by technology

[0002] In the prior art, the foam dust suppression device is installed on the fixing bolts of the cantilever section of the fully mechanized excavator and the reducer. Due to the relatively high hardness of the rock in the roadway, the vibration of the cutting arm of the fully mechanized excavator is relatively large during excavation. After installation, the fixing bolts may be damaged. The damage of the reducer or the cantilever section affects production; in the prior art, the foam dust suppression device is easily damaged due to long-term vibration during use, and the service life is shortened; in the prior art, the installation and operation of the foam dust suppression device It is cumbersome, time-consuming and labor-intensive, so a fully mechanized excavator foam dust suppression device installation mechanism is needed to solve the above problems
