Description

Technical Field

[0001] The utility model relates to the technical field of connection structures, in particular to a connection structure for replacing a broken steel wire rope of a coal conveying belt. Background Art

[0002] At present, the method of replacing the belt of a coal conveyor is generally to pull a wire rope on the old belt, and manually pull the wire rope with a hand winch to drag the old belt out section by section. When laying a new belt, pull the wire rope on the new belt, and manually drag the new belt with a hand winch to lay it on the coal conveyor.

[0003] The above method leads to a long operation time. After searching, the prior art (application number: CN202010270039.0) records "a method for replacing a coal conveyor belt, comprising the following steps: cutting off the old belt and dividing the old belt into a replacement part and a retained part; hoisting a new belt, pulling the end of the new belt to one of the cut-offs of the replacement part for connection; connecting a steel wire rope to the other cut-off of the replacement part, and connecting one end of the steel wire rope to a power component; starting the power component, the old belt is pulled out from the roller of the coal conveyor under the traction of the steel wire rope, and at the same time, the replacement part pulls the new belt to be laid on the roller of the coal conveyor; and the new belt is connected to the retained part. When replacing the old belt, the new belt and the old belt can be replaced at the same time, which effectively shortens the replacement time of the coal conveyor belt and reduces the downtime of the coal conveyor."

[0004] The clamping device involved in the above technology does not have a related structure, and the clamping device usually used for the broken end of the coal conveyor belt is tightened after being pierced by screws, or directly two clamping blocks are clamped close together and then connected to the outer pulling mechanism through a wire rope. The use of screw piercing leads to low efficiency, and at the same time, the connection end of the belt will be damaged on the new belt used for replacement. Secondly, the use of clamping blocks for clamping will lead to poor stability of the belt and easy loosening during the pulling process. Utility Model Content
