Reinforced frame of full-section broken belt protection device for belt conveyor

Abstract

The invention discloses a reinforced frame of a full-section broken belt protection device for a belt conveyor and belongs to a protection device for the belt conveyor. A stable reinforced frame having a triangular structure is arranged on the two sides of a stander of the full-section broken belt protection device respectively and comprises a long connecting rod, a short connecting rod, an inclined connecting rod, a connecting rod, a big base, and a small base, wherein one end of the long connecting rod is connected with an upper part of the stander, and the other end of the long connecting rod is connected with the small base; one end of the short connecting rod and one end of the inclined connecting rod are both connected with a middle part of the stander; the other end of the short connecting rod is connected with the middle part of the long connecting rod; the other end of the inclined connecting rod is connected with the big base; and one end of the connecting rod is connected with the middle part of the long connecting rod, and the other end of the connecting rod is connected with the big base. The connections form a stable triangular structure consisting of a plurality of triangles. The reinforced frame has the advantage that: the stable triangular structure consisting of the plurality of triangles effectively resists impact force from the outside and protects the safety of equipment.

Description

technical field [0001] The invention relates to a full-section belt-breaking protection device for a belt conveyor, in particular to a reinforcing frame for the full-section belt-breaking protection device for a belt conveyor. Background technique [0002] Belt conveyors are widely used in mining, metallurgy, chemical industry, light industry, coal, ports and many other fields. Especially on large-angle conveyors, the occurrence of belt breakage accidents will basically lead to the tragedy of machine destruction and death, causing huge losses to the country and enterprises, and harm to people's lives; The distance is long, the working environment is harsh, and the maintenance is very inconvenient. The State Administration of Work Safety, the State Administration of Coal Mine Safety Supervision and Supervision, and the China Coal Industry Association have specially issued Article 375 of the "Coal Mine Safety Regulations" and "Coal Mine Safety Quality Standardization Standard...

AI Technical Summary

Problems solved by technology

[0003] In recent years, some broken belt arresting devices have appeared on the market. In summary, most of the braking mechanisms are cams, eccentric wheels, cranks, etc., which clamp the sliding tape during braking, with small braking force and high reliability. It is not high, and at the same time, the line contact is easy to cause shearing on the edges of both sides of the tape and damage the tape. In severe cases, the tape will be torn; , For example, when the belt conveyor stops normally, the belt continues to go up by inertia and then stops. Although a backstop or brake is installed, it will slide down for a certain distance under the action of gravity, which will cause false braking

The above structure cannot effectively resist the external impact force, it is easy to damage the equipment, and cause accidents in serious cases
