O-shaped anti-skidding cable plywood for coal mining machine

Abstract

The invention provides O-shaped anti-skidding cable plywood for a coal mining machine, belonging to the technical field of cable sheath fixtures. The coal mining machine can safely works on inclined fully mechanized faces by using the O-shaped anti-skidding cable plywood. The technical points are as follows: a cable clamp is composed of a left backing plate and a right backing plate with steel core injection molding structures, as well as an upper and a lower connecting plate; the upper and the lower ends of a left support frame and a right support frame are respectively provided with symmetrical mortises; the front and the back ends of the left support frame and the right support frame are respectively provided with metal yokes and connecting pieces; the left and the right ends of the upper and the lower connecting plate are respectively provided with a tenon, and the tenons are matched with the mortises on the left and the right support frame; the tops of the left and right support frame (1) are respectively provided with an anti-skidding tooth (14), and the lower middle parts of the left and the right support frames (1) are respectively provided with an open cavity; and the open cavities are internally provided with an approximately 7-shaped non-return paw (4) respectively, wherein the non-return paws are formed by horizontally installing tapping screws at the outer sides of the left and the right support frames.

Description

technical field [0001] The invention relates to an O-shaped anti-slip cable splint for coal mining machines, belonging to the technical field of cable sheath fixtures. technical background [0002] With the development and progress of coal mining technology and mechanized fully mechanized mining technology and the improvement of production capacity, fully mechanized mining equipment and equipment are becoming more and more large-scale. The cross-section and cross-sectional diameter of shearer power cables are getting larger and heavier. Especially under the production conditions of the longer fully mechanized mining face (above 300m), the protection work of the power cable of the shearer will be more difficult. Chinese patent 200920143217.2 discloses a mortise riveting assembly type O-shaped cable clamp for mining coal mining machines. Although it solves the protection function and protection strength requirements of the power cable of large-scale fully mechanized mining eq...

Problems solved by technology

Especially under the production conditions of longer fully mechanized mining face (above 300m), the protection work of the power cable of the coal mining machine will be more difficult

Chinese patent 200920143217.2 discloses a mortise riveting assembly type O-shaped cable clamp for mining coal mining machines. Although it solves the protection function and protection strength requirements of the power cable of large-scale fully mechanized mining equipment, it is difficult to use it on an inclined (above 15°) fully mechanized mining face. Not yet mentioned on the cable slip issue

Once the slide occurs, the entire cable clamp chain and cable will slide faster and faster, forming a huge impact force, which cannot be stopped by manpower and general external force, resulting in huge damage and serious damage to the personnel and facilities of the cable and fully mechanized mining face. threaten
