Problems solved by technology

[0003] 1. The process is complex and the project takes a long time
[0004] 2. The entire construction process is manually operated, which consumes a lot of manpower and has low work efficiency
[0005] 3. Recycled old tapes have been destroyed, cannot be reused, and are wasted
[0006] 4. The lifting of new tapes and the recycling of old tapes require the cooperation of many people in the construction, and the safety is low

Embodiment Construction

[0020] The present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0021] like figure 1 As shown, the main belt conveyor 1 of the north wing is driven by two 160KW three-phase asynchronous motors, with a designed transportation capacity of 400t / h and a total length of 1200 meters; the main belt conveyor 2 of the second north wing is a 250-type small belt conveyor. Type conveyor, driven by two 125kw three-stage asynchronous motors, with a total length of 460 meters; the main conveyor belt conveyor 3 of the third part of the north wing, with the same installed capacity and driving mode as the main conveyor belt conveyor of the second part of the north wing, with a total length of 1100 meters; No. 2 coal bunker 4, the lower port is connected to the coal feeder in the loading chamber, and then lifted to the ground through the skip of the main shaft. The entire north wing belt conveyor transportation system is sta...

Abstract

The invention discloses a belt replacing method for coal mine belt conveyors. According to the method, the system structure of the two existing belt conveyors and the roadway environment structure are utilized, a double-speed prop pulling hoist is mounted on each conveyor head, new belts and used belts are mechanically connected by fully utilizing traction force of the prop pulling hoists and the two belt conveyors, and the used belts slide to drag the new belts to slowly enter the belt conveyors; and after the new belts and the used belts are circulated for a circle, replacing of the used belts with the new belts is achieved, and meanwhile, recycling of the whole used belts is achieved. By means of the method, synchronous replacement of the belts of the two cross-heading conveyors for a coal mine is achieved, and the method has the construction advantages of safety, high efficiency and time and labor saving, and promotes safety production of the mine.

Description

technical field [0001] The invention relates to the technical field of mine transportation machinery and equipment, in particular to a method for replacing a belt of a coal mine belt conveyor. Background technique [0002] At present, large and medium-sized coal mines at home and abroad are equipped with raw coal transportation systems. The belt conveyor is the main artery of raw coal transportation, and it continuously transports the recovered raw coal out of the mine every day. Roll-by-roll replacement is commonly used to replace tapes of underground tape machines in coal mines, and it is only applicable to the construction of a single tape machine. The specific method of replacement is as follows: firstly, hoist a bundle of new tape facing the head or tail of the tape machine, pull the new belt to the old tape machine with a hand chain hoist or manpower, turn the tape machine upside down or forward, and bring the new tape into the The conveyor lane overlaps with the old ...
