AI Technical Summary

Technical Problem

In existing mechanical canvas covering devices, the traction cable is prone to sink into the coal pile on the top of the coal pile, causing the canvas to be unable to cover the entire coal pile, increasing the workload and safety risks.

Method used

A device for traction steel cables to prevent falling is designed, including two base plates that are hinged with each other. Each base plate has a set of bearing seats on the upper part of the base plate. The cable passes through the coal pile guided by the bearing seat and the roller shaft. A lead screw is arranged between the two base plates to adjust the angle between the two base plates, and a fixed rod is provided on the outside of each base plate.

Benefits of technology

Through this device, the steel cable leaves the coal pile on both sides of the coal pile, avoiding falling into it, reducing friction and wear, improving work efficiency and safety, adapting to the inclination angles of the tops of different coal piles, and being better fixed to the coal pile.

Abstract

A device for preventing a traction steel cable from falling comprises two bottom plates hinged to each other, the upper portion of each bottom plate is provided with a group of bearing seats, each group of bearing seats is rotatably connected with a roll shaft, the steel cable crosses a coal pile under the guidance of the bearing seats and the roll shafts, a lead screw for adjusting the included angle of the two bottom plates is arranged between the two bottom plates, and a fixing rod is arranged on the outer side of each bottom plate. The two hinged bottom plates are placed at the top of a coal pile, so that the steel cable can leave the coal pile on the two sides of the coal pile and is prevented from falling into the coal pile, the outer contour diameter of each bearing seat is larger than the diameter of the roller shaft, and the steel cable can slide between the bearing seats on the two sides when bypassing the device, so that the steel cable can be prevented from being separated from the device; the rotating roll shaft can isolate the steel cable from the coal pile and prevent the steel cable from falling into the coal pile, sliding friction of the steel cable and the roll shaft is converted into rolling friction, friction force is greatly reduced, abrasion of the steel cable is reduced, the included angle of the two bottom plate supports can be adjusted through the lead screw, and the device can adapt to inclination angles of the tops of different coal piles. Meanwhile, the distance between the steel cable and the top of the coal pile can be adjusted, the steel cable is further prevented from making contact with the coal pile, the fixing rods are inserted into the coal pile, the device and the coal pile can be better fixed, and the device is prevented from shaking when pressed.
