Tensioning device of steel wire rope of bulk machine

Abstract

The invention discloses a tensioning device of a steel wire rope of a bulk machine, and relates to the technical field of bulk machines. The tensioning device comprises a base, a driving motor, a speed reducer and three hollow vertical columns, wherein the driving motor, the speed reducer and the three hollow vertical columns are arranged on the base; and the driving motor is fixedly installed onthe base and is connected with a central rotating shaft through the speed reducer, three winding groove wheels are fixed on the central rotating shaft, a steel wire rope is fixedly connected to each winding groove wheel, a lifting heavy hammer is arranged in each hollow vertical column, and the three steel wire ropes wind around the three lifting heavy hammers and then are fixedly connected with the bottom of a telescopic discharging pipe. The tensioning device of the steel wire rope of the bulk machine has the technical effects that the steel wire ropes are kept in a proper tensioning state,the steel wire ropes are prevented from being loosened, twisted, knotted or too tight and even broken.

Description

technical field [0001] The invention relates to the technical field of bulk machines, in particular to a wire rope tensioning device for bulk machines. Background technique [0002] Bulk packing machine is a kind of packaging equipment, which is used to output the materials in the storage warehouse to the means of transportation such as trucks and tankers. Commonly used bulk loaders include clinker bulk loader, silo bottom bulk loader, silo side bulk loader, dry ash (slag) bulk loader, etc. Among them, dry ash (slag) bulk loader is suitable for electric power, building materials, chemical industry and other industries. The bottom of the bulk machine is usually equipped with a telescopic feeding tube, which is generally formed by a number of sleeve-type expansion joints, and a number of steel wire ropes are fixedly connected to a sleeve expansion joint at the bottom. The roll device realizes the expansion and contraction of the telescopic feeding tube. The traditional steel...

AI Technical Summary

Problems solved by technology

[0004] The existing technical solution above has the following defects: in this solution, the three steel wire ropes are driven by the motor to rotate the reel to realize synchronous rewinding and unwinding, but if the staff does not see the telescopic feeding tube in time. If the motor is not turned off in time, the wire rope will be slack, twisted, knotted or the wire rope will be too tight or even broken, which will affect the normal feeding in light cases, and cause safety accidents in severe cases
