Rapid retraction method for belt conveyer and tape handler for retraction

Abstract

The invention provides a rapid retraction method for a belt conveyer and a tape handler for retraction, and belongs to the technical field of underground coal mine fully-mechanized excavation face belt conveyers. The problems that a traditional belt demounting process mainly depends on manual operation, so that the labor intensity is large, the retraction time is long, and the work efficiency is low are mainly solved. The rapid retraction method includes the steps of selecting subsection cut-off points or butt joint points, cutting off a belt, tape winding and recovering a belt piece. The rapid retraction method is characterized by comprising the following specific steps: (1) selecting the subsection cut-off points or the butt joint points; (2) cutting off the belt at the cut-off points; (3) retracting AC belt sections at the lower portions; (4) retracting AD belt sections, and meanwhile recovering an upper carrier roller; (5) retracting CD belt sections, and meanwhile recovering the belt piece; and (6) retracting a driving part and a belt conveyor head large frame after retraction of all belts is finished, and retracting the tape handler. The tape handler for retraction comprises a power device, a tape winding shaft and a machine frame. The tape handler is characterized by further comprising filter belt centering devices symmetrically arranged on stand columns of the machine frame.

Description

technical field [0001] The invention belongs to the technical field of belt conveyors in fully mechanized excavation working faces in coal mines, and in particular relates to a method for fast retraction of belt conveyors in fully mechanized excavation working faces in coal mines and a belt winder for retracing. Background technique [0002] Comprehensive mechanized tunneling must involve the installation and withdrawal of tunneling belts. The installation of the belt is carried out step by step with the advancement of the working face, and the extension will generally not affect the progress of the project; after the excavation of the roadway, the belt retraction of more than 1,000 meters, or even two to three kilometers, will be a very heavy task. Work, the speed of its retracement and the choice of retracement method often have a great impact on the follow-up work. [0003] The traditional process of removing the belt mainly relies on manual operation. After the belt is ...

The installation of the belt is carried out step by step with the advancement of the working face, and the extension will generally not affect the progress of the project; after the excavation of the roadway, the belt retraction of more than 1,000 meters, or even two to three kilometers, will be a very heavy task. Work, the speed of its withdrawal and the choice of withdrawal method often have a great impact on the follow-up work

[0003] The traditional process of removing the belt mainly relies on manual operation. After the belt is pulled out and threaded, the belt is placed on the side of the roadway, and the belt is manually rolled up and then loaded and transported out. Low level defects
